Stereoselective Iron-Catalyzed Alkylation of Enamides with Cyclopropanols via Oxidative C(sp2)-H Functionalization. Established herein is a radical-mediated C-H alkylation of enamides with cyclopropanols. An environmentally benign catalytic system with iron salt and air is used to permit the oxidative coupling process. The protocol demonstrates a broad substrate scope, allowing the stereoselective synthesis of alkylated enamides. The value of this strategy is further reflected by late-stage diversification of complex cyclopropanol-containing molecules and downstream transformations. Mechanistic studies reveal the dual role of iron salt in the reaction.

METHODS: Serial sections were evaluated by immunohistochemistry after staining with antibodies against p27/Kip1 and Ki-67 in surgical material obtained from 36 patients with GIST. p27kip1 staining intensity and the percentage of positive cells were investigated for association with the malignancy risk, pathological features, overall survival, and disease-free survival.

Intestinal epithelial cell differentiation: new insights from mice, flies and nematodes. Decisions commonly made during development that affect proliferation, cell fate specification, differentiation, migration, and death are made repeatedly in the mouse small intestinal epithelium throughout adulthood.

Mononuclear nickel(III) and nickel(II) thiolate complexes with intramolecular S-H proton interacting with both sulfur and nickel: relevance to the [NiFe]/[NiFeSe] hydrogenases. Mononuclear, distorted square planar [Ni(II)(ER)(P(o-C(6)H(4)S)(2)(o-C(6)H(4)SH))](-) (ER = SePh (1), 2-S-C(4)H(3)S (2)) with a S-H proton directly interacting with both nickel and sulfur atoms were prepared by reaction of [Ni(CO)(SePh)(3)](-)/[Ni(CO)(2-S-C(4)H(3)S)(3)](-) and P(o-C(6)H(4)SH)(3), individually. The presence of combinations of intramolecular [Ni-S...H-SR]/[Ni...H-SR] interactions was verified in the solid state by the observation of an IR nu(SH) stretching band (2273 and 2283 cm(-)(1) (KBr) for complexes 1 and 2, individually) and (1)H NMR spectra (delta 8.079 (d) (CD(2)Cl(2)) and 8.39 (d) (C(4)D(8)O) ppm (-SH) for complexes 1 and 2, respectively) and subsequently confirmed by X-ray diffraction study. The exo-thiol proton (o-C(6)H(4)SH) in complexes 1 and 2 was identified as a D(2)O exchangeable proton from NMR and IR studies and was quantitatively removed by Lewis base Et(3)N to yield Ni(II) dimer [Ni(II)(P(o-C(6)H(4)S)(3))](2)(2)(-) (5). Instead of the ligand-based oxidation to form dinuclear Ni(II) complexes and dichalcogenide, oxidation of THF-CH(3)CN solution of complexes 1 and 2 by O(2) resulted in the formation of the mononuclear, distorted trigonal bipyramidal [Ni(III)(ER)(P(o-C(6)H(4)S)(3))](-) (ER = SePh (3), 2-S-C(4)H(3)S (4)) accompanied by byproduct H(2)O identified by (1)H NMR, respectively. The 4.2 K EPR spectra of complexes 3 and 4 exhibiting high rhombicities with three principal g values of 2.304, 2.091, and 2.0 are consonant with Ni(III) with the odd electron in the d(z)(2) orbital.

RP is documented to affect up to 5% of the general population, but variation in its prevalence is commonly recognized owing to many factors, including varied definitions, gender, genetics, hormones, and region. Furthermore, RP may be idiopathic or be a clinical manifestation of an underlying illness. Patients with RP classically describe a triphasic discoloration of the affected area, beginning with pallor, followed by cyanosis, and finally ending with erythema. This change in color spares the thumb and is often associated with pain. Each attack may persist from several minutes to hours. Moreover, the transient cessation of blood flow in RP is postulated to be mediated by neural and vascular mechanisms. Both structural and functional alterations observed in the blood vessels contribute to the vascular abnormalities documented in RP. However, functional impairment serves as a primary contributor to the pathophysiology of primary Raynaud's. Substances like endothelin-1, angiotensin, and angiopoietin-2 play a significant role in the vessel-mediated pathophysiology of RP. The role of nitric oxide in the development of this phenomenon is still complex. Neural abnormalities resulting in RP are recognized as either being concerned with central mechanisms or peripheral mechanisms. CNS involvement in RP may be suggested by the fact that emotional distress and low temperature serve as major triggers for an attack, but recent observations have highlighted the importance of locally produced factors in this regard as well. Impaired vasodilation, increased vasoconstriction, and several intravascular abnormalities have been documented as potential contributors to the development of this disorder. RP has also been observed to occur as a side effect of various drugs. Recent advances in understanding the mechanism of RP have yielded better pharmacological therapies. However, general lifestyle modifications along with other nonpharmacological interventions remain first-line in the management of these patients.

Raynaud's Phenomenon: Reviewing the Pathophysiology and Management Strategies. Raynaud's phenomenon (RP) is a multifactorial vasospastic disorder characterized by a transient, recurrent, and reversible constriction of peripheral blood vessels. RP is documented to affect up to 5% of the general population, but variation in its prevalence is commonly recognized owing to many factors, including varied definitions, gender, genetics, hormones, and region. Furthermore, RP may be idiopathic or be a clinical manifestation of an underlying illness. Patients with RP classically describe a triphasic discoloration of the affected area, beginning with pallor, followed by cyanosis, and finally ending with erythema. This change in color spares the thumb and is often associated with pain. Each attack may persist from several minutes to hours. Moreover, the transient cessation of blood flow in RP is postulated to be mediated by neural and vascular mechanisms. Both structural and functional alterations observed in the blood vessels contribute to the vascular abnormalities documented in RP. However, functional impairment serves as a primary contributor to the pathophysiology of primary Raynaud's. Substances like endothelin-1, angiotensin, and angiopoietin-2 play a significant role in the vessel-mediated pathophysiology of RP. The role of nitric oxide in the development of this phenomenon is still complex. Neural abnormalities resulting in RP are recognized as either being concerned with central mechanisms or peripheral mechanisms. CNS involvement in RP may be suggested by the fact that emotional distress and low temperature serve as major triggers for an attack, but recent observations have highlighted the importance of locally produced factors in this regard as well. Impaired vasodilation, increased vasoconstriction, and several intravascular abnormalities have been documented as potential contributors to the development of this disorder. RP has also been observed to occur as a side effect of various drugs. Recent advances in understanding the mechanism of RP have yielded better pharmacological therapies. However, general lifestyle modifications along with other nonpharmacological interventions remain first-line in the management of these patients. Calcium channel blockers, alpha-1 adrenoreceptor antagonists, angiotensin-converting enzyme inhibitors, nitric oxide, prostaglandin analogs, and phosphodiesterase inhibitors are some of the common classes of drugs that have been found to be therapeutically significant in the management of RP. Additionally, anxiety management, measures to avoid colder temperatures, and smoking cessation, along with other simple modifications, have proven to be effective non-drug strategies in patients experiencing milder symptoms.

The surface chemistry of medical device coatings is important in controlling and/or preventing fouling. In this study, we have shown that a combination of nitric oxide releasing hydrophobic polymer with a hydrophilic polymer topcoat can significantly reduce protein attachment and subsequently reduce bacterial adhesion as a result of the synergistic effect. Nitric oxide (NO) is a well-known potent antibacterial agent due to its adverse reactions on microbial cell components. Owing to the surface chemistry of hydrophilic polymers, they are suitable as antifouling topcoats. In this study, four biomedical grade polymers were compared for protein adhesion and NO-release behavior: CarboSil 2080A, silicone rubber, SP60D60, and SG80A. SP60D60 was found to resist protein adsorption up to 80% when compared to the other polymers while CarboSil 2080A maintained a steady NO flux even after 24 hours (~0.50 x 10-10 mol cm-2 min-1) of soaking in buffer solution with a loss of less than 3% S-nitroso-N-acetylpenicillamine (SNAP), the NO donor molecule, in the leaching analysis. Therefore, CarboSil 2080A incorporated with SNAP and top-coated with SP60D60 was tested for antibacterial efficacy after exposure to fibrinogen, an abundantly found protein in blood. The NO-releasing CarboSil 2080A with the SP60D60 top-coated polymer showed a 96% reduction in Staphylococcus aureus viable cell count compared to the control samples.

Enhanced antibacterial efficacy of nitric oxide releasing thermoplastic polyurethanes with antifouling hydrophilic topcoats. Surface fouling is one of the leading causes of infection associated with implants, stents, catheters, and other medical devices. The surface chemistry of medical device coatings is important in controlling and/or preventing fouling. In this study, we have shown that a combination of nitric oxide releasing hydrophobic polymer with a hydrophilic polymer topcoat can significantly reduce protein attachment and subsequently reduce bacterial adhesion as a result of the synergistic effect. Nitric oxide (NO) is a well-known potent antibacterial agent due to its adverse reactions on microbial cell components. Owing to the surface chemistry of hydrophilic polymers, they are suitable as antifouling topcoats. In this study, four biomedical grade polymers were compared for protein adhesion and NO-release behavior: CarboSil 2080A, silicone rubber, SP60D60, and SG80A. SP60D60 was found to resist protein adsorption up to 80% when compared to the other polymers while CarboSil 2080A maintained a steady NO flux even after 24 hours (~0.50 x 10-10 mol cm-2 min-1) of soaking in buffer solution with a loss of less than 3% S-nitroso-N-acetylpenicillamine (SNAP), the NO donor molecule, in the leaching analysis. Therefore, CarboSil 2080A incorporated with SNAP and top-coated with SP60D60 was tested for antibacterial efficacy after exposure to fibrinogen, an abundantly found protein in blood. The NO-releasing CarboSil 2080A with the SP60D60 top-coated polymer showed a 96% reduction in Staphylococcus aureus viable cell count compared to the control samples. Hence, the study demonstrated that a hydrophilic polymer topcoat, when applied to a polymer with sustained NO release from an underlying SNAP incorporated hydrophobic polymer, can reduce bacterial adhesion and be used as a highly efficient antifouling, antibacterial polymer for biomedical applications.

[Anti-arrhythmia and electrophysiological effects of encainide in supraventricular tachycardias]. In order to assess the electrophysiologic effects and anti-arrhythmia effects of encainide after acute IV injection and chronic oral therapy, a group of 10 patients (mean age 54) with recurrent supraventricular tachycardia was studied. Seven patients had more than 2 attacks per month, and supraventricular tachycardia (SVT) resulted in severe symptoms in the three remaining SVT was due to AV nodal re-entry in 6 patients and to concealed accessory pathway in 4. After a control study, SVT was initiated, and encainide (0.75 mg/kg) was infused intravenously in attempt to stop the tachycardia. A second study was achieved. After 4 days of oral therapy (25 or 50 mg T.I.D.) a third study was performed, including SVT initiation attempts. Encainide depressed conduction in all cardiac tissues, and this effect was more evident after oral administration. Antegrade I:I conduction cycle length increased of 13.9% (p less than 0.05), and the same parameter in retrograde conduction increased of 30.03% (p less than 0.05). IV injection interrupted 2 of 10 SVT only. However, after 30 minutes, 5 re-initiated SVT were nonsustained, and mean cycle length increased from 326 +/- 21 to 397 +/- 51 (p less than 0.01). After oral therapy, SVT was initiated in 4 of 10 patients, nonsustained in 3. During long term follow-up (one year or more), no severe adverse effect has been reported. Three patients are still experiencing short events of well-tolerated SVT. Hence, moderate or low doses or oral encainide may safely control recurrent supraventricular tachycardia.

There was a trend for the capillary diffusion areas (the muscle area supplied by each capillary) to be larger in the IGT group for the IIa (1,132+/-286 vs. 1,013+/-240 microm2, P = 0.061) and IIx fibers (1,020+/-246 vs. 906+/-240 microm2, P = 0.058). In the entire group, insulin sensitivity correlated with the size of the type IIa fibers (r = -0.28, P = 0.013), but not with the percentages of muscle fiber types. In a multiple regression, insulin sensitivity was determined by body fat content and HDL cholesterol level, while the size of the IIa fibers was not included in the model. Glucose tolerance was independently predicted by the number of capillaries/type I fiber, as well as by insulin sensitivity and triglyceride levels. CONCLUSIONS: We conclude that although muscle fiber composition is not altered, women with IGT have larger type IIa and IIx muscle fibers and a trend for increased capillary diffusion areas for these fibers, compared with women with NGT. In the entire group, insulin sensitivity was determined mainly by body fat content, while muscle fiber capillarization may be of importance for glucose tolerance." ], "offsets": [ [ 96, 2138 ] ] } ]

Muscle fiber characteristics in postmenopausal women with normal or impaired glucose tolerance. OBJECTIVE: Muscle fiber characteristics are altered in type 2 diabetes. We studied whether these alterations also exist in impaired glucose tolerance (IGT) and whether they are determinants of insulin sensitivity and glucose tolerance in postmenopausal women. RESEARCH DESIGN AND METHODS: Percutaneous muscle biopsies from the vastus lateralis muscle were obtained from 77 postmenopausal women aged 57-59 years: 50 women with normal glucose tolerance (NGT) and 27 with IGT. The IGT group had a reduced insulin sensitivity compared with the NGT group (euglycemic-hyperinsulinemic clamp) (P = 0.003). RESULTS: The groups did not differ in muscle fiber composition, as judged by the percentage of type I, IIa, or IIx fibers. In contrast, the IGT group had increased size of the IIa (mean +/-SD 3,776+/-987 vs. 3,078+/-862 microm2, P = 0.002) and IIx fibers (2,730+/-1,037 vs. 2,253+/-672 microm2, P = 0.017). There was a trend for the capillary diffusion areas (the muscle area supplied by each capillary) to be larger in the IGT group for the IIa (1,132+/-286 vs. 1,013+/-240 microm2, P = 0.061) and IIx fibers (1,020+/-246 vs. 906+/-240 microm2, P = 0.058). In the entire group, insulin sensitivity correlated with the size of the type IIa fibers (r = -0.28, P = 0.013), but not with the percentages of muscle fiber types. In a multiple regression, insulin sensitivity was determined by body fat content and HDL cholesterol level, while the size of the IIa fibers was not included in the model. Glucose tolerance was independently predicted by the number of capillaries/type I fiber, as well as by insulin sensitivity and triglyceride levels. CONCLUSIONS: We conclude that although muscle fiber composition is not altered, women with IGT have larger type IIa and IIx muscle fibers and a trend for increased capillary diffusion areas for these fibers, compared with women with NGT. In the entire group, insulin sensitivity was determined mainly by body fat content, while muscle fiber capillarization may be of importance for glucose tolerance.

Candesartan cilexetil-induced severe hepatotoxicity. We report a case of severe hepatotoxicity associated with ductopenia in a 61-year-old woman. The patient developed jaundice, vomiting, and abdominal pain a few weeks after the beginning of treatment with candesartan cilexetil, 16 mg/d, for essential hypertension. Liver biopsy showed parenchymal bilirubinostasis with portal cholangitis and ductopenia. The drug was immediately withdrawn, and in the following weeks, aminotransferases and serum bilirubin returned to normal levels. The clinical-histologic data and the exclusion of known causes of liver disease led us to make a diagnosis of drug-induced cholestasis. To our knowledge, this is the first description of severe hepatotoxicity associated with ductopenia caused by an adverse reaction to candesartan cilexetil.

Methods: The product was a water-in-oil (W/O) emulsion containing the active ingredients Avene thermal spring water, sucralfate, and copper and zinc sulfates. In total, 32 subjects suffering from either contact dermatitis or climatic dermatitis participated in the trial. The modified total lesion symptom score and physician global assessment scores were used to describe the severity of HE. The safety of the product was assessed through clinical scoring. The subjective tolerance, and acceptance, were documented using a self-assessment questionnaire completed by the subjects. The impact of the dermatosis on QoL was evaluated using the Dermatology Life Quality Index. Results: After 7 days of application, both the physician and subjects noticed a significant improvement in HE. The formula was very well tolerated and accepted.

A novel dermo-cosmetic product containing thermal spring water, sucralfate, copper sulfate, and zinc sulfate in the management of hand eczema. Background: The regular use of cosmetic products plays a role in the management of hand eczema (HE) and aids in improving barrier function reducing dryness, roughness, pruritus and improving quality of life (QoL). The aim of this open-label study was to assess the efficacy and the reparative effect of a dermo-cosmetic product on subjects suffering from HE after 7 and 21 days of daily application. Methods: The product was a water-in-oil (W/O) emulsion containing the active ingredients Avene thermal spring water, sucralfate, and copper and zinc sulfates. In total, 32 subjects suffering from either contact dermatitis or climatic dermatitis participated in the trial. The modified total lesion symptom score and physician global assessment scores were used to describe the severity of HE. The safety of the product was assessed through clinical scoring. The subjective tolerance, and acceptance, were documented using a self-assessment questionnaire completed by the subjects. The impact of the dermatosis on QoL was evaluated using the Dermatology Life Quality Index. Results: After 7 days of application, both the physician and subjects noticed a significant improvement in HE. The formula was very well tolerated and accepted. These benefits were correlated with a significant improvement in QoL. Conclusion: The W/O emulsion used in this study demonstrated real benefits for the subjects suffering from contact dermatitis and climatic dermatitis.

Which role for EGFR therapy in breast cancer? EGFR and HER2 are highly expressed in 15-30% of breast cancer tissues. Therefore, EGFR and its downstream signaling pathways are promising anti-tumour targets. HER2 overexpression is often associated with estrogen receptor (ER) and progesterone receptor (PR) negativity, high histological grade, high rates of cell proliferation and lymph node involvement. Moreover, it is correlated with disease aggressiveness, increased rates of recurrence and poorer survival in node-positive breast cancer patients, whereas the prognostic significance in patients with node-negative tumors remains somewhat controversial. This paper focuses on the therapeutic strategy for treatment of HER2 overexpressing breast cancer in advanced stages of disease, as well as in the adjuvant and neo-adjuvant settings.

The increased incidence of PTC in patients with thyroiditis and the frequent immune infiltrate found in PTC suggest that inflammation might be a risk factor for PTC development. The CXCR3-ligand system is involved in thyroid inflammation and CXCR3 has been found upregulated in many tumors, suggesting its pro-tumorigenic role under the inflammatory microenvironment. CXCR3 ligands (CXCL4, CXCL9, CXCL10 and CXCL11) trigger antagonistic responses partly due to the presence of two splice variants, CXCR3A and CXCR3B. Whereas CXCR3A promotes cell proliferation, CXCR3B induces apoptosis. However, the relation between CXCR3 variant expression with chronic inflammation and PTC development remains unknown. Here, we characterized the expression pattern of CXCR3 variants and their ligands in benign tumors and PTC. We found that CXCR3A and CXCL10 mRNA levels were increased in non-metastatic PTC when compared to non-neoplastic tissue. This increment was also observed in a PTC epithelial cell line (TPC-1). Although elevated protein levels of both isoforms were detected in benign and malignant tumors, the CXCR3A expression remained greater than CXCR3B and promoted proliferation in Nthy-ori-3-1 cells. In non-metastatic PTC, inflammation was conditioning for the CXCR3 ligands increased availability. Consistently, CXCL10 was strongly induced by interferon gamma in normal and tumor thyrocytes. Our results suggest that persistent inflammation upregulates CXCL10 expression favoring tumor development via enhanced CXCR3A-CXCL10 signaling. These findings may help to further understand the contribution of inflammation as a risk factor in PTC development and set the basis for potential therapeutic studies." ], "offsets": [ [ 156, 1937 ] ] } ]

Differential expression profile of CXCR3 splicing variants is associated with thyroid neoplasia. Potential role in papillary thyroid carcinoma oncogenesis? Papillary thyroid cancer (PTC) is the most prevalent endocrine neoplasia. The increased incidence of PTC in patients with thyroiditis and the frequent immune infiltrate found in PTC suggest that inflammation might be a risk factor for PTC development. The CXCR3-ligand system is involved in thyroid inflammation and CXCR3 has been found upregulated in many tumors, suggesting its pro-tumorigenic role under the inflammatory microenvironment. CXCR3 ligands (CXCL4, CXCL9, CXCL10 and CXCL11) trigger antagonistic responses partly due to the presence of two splice variants, CXCR3A and CXCR3B. Whereas CXCR3A promotes cell proliferation, CXCR3B induces apoptosis. However, the relation between CXCR3 variant expression with chronic inflammation and PTC development remains unknown. Here, we characterized the expression pattern of CXCR3 variants and their ligands in benign tumors and PTC. We found that CXCR3A and CXCL10 mRNA levels were increased in non-metastatic PTC when compared to non-neoplastic tissue. This increment was also observed in a PTC epithelial cell line (TPC-1). Although elevated protein levels of both isoforms were detected in benign and malignant tumors, the CXCR3A expression remained greater than CXCR3B and promoted proliferation in Nthy-ori-3-1 cells. In non-metastatic PTC, inflammation was conditioning for the CXCR3 ligands increased availability. Consistently, CXCL10 was strongly induced by interferon gamma in normal and tumor thyrocytes. Our results suggest that persistent inflammation upregulates CXCL10 expression favoring tumor development via enhanced CXCR3A-CXCL10 signaling. These findings may help to further understand the contribution of inflammation as a risk factor in PTC development and set the basis for potential therapeutic studies.

The complex nature of behavioral, psychological, emotional, and neuropathological characteristics associated with alcoholism is likely a reflection of the network of proteins that are affected by alcohol-induced gene expression patterns in specific brain regions.

Thus, novel techniques that allow a comprehensive assessment of this complexity will enable the simultaneous assessment of changes across a group of proteins in the relevant neural circuitry. METHODS: A proteomics analysis was performed using antibody microarrays to determine differential protein levels in superior frontal cortices between chronic alcoholics and age- and gender-matched control subjects. Seventeen proteins related to the catenin signaling pathway were analyzed, including alpha-, beta-, and delta-catenins, their upstream activators cadherin-3 (type I cadherin) and cadherin-5 (type II cadherin), and 5 cytoplasmic regulators c-Src, CK1 epsilon, GSK-3beta, PP2A-C alpha, and APC, as well as the nuclear complex partner of beta-catenin CBP and 2 downstream genes Myc and cyclin D1. ILK, G(alpha1), G(beta1), and G(beta2), which are activity regulators of GSK-3beta, were also analyzed. RESULTS: Both alpha- and beta-catenin showed significantly increased levels, while delta-catenin did not change significantly, in chronic alcoholics. In addition, the level of the beta-catenin downstream gene product Myc was significantly increased. Average levels of the catenin regulators c-Src, CK1 epsilon, and APC were also increased in chronic alcoholics, but the changes were not statistically significant. CONCLUSION: Chronic and excessive alcohol consumption leads to an upregulation of alpha- and beta-catenin levels, which in turn increase downstream gene expressions such as Myc that is controlled by beta-catenin signaling.

Assessment of the extent to which the program achieves its aims will depend on a full understanding of how individual, organizational, and environmental factors align (or fail to align) to achieve these improvements, and at what cost.

METHODS: A multi-database electronic search was performed to provide an overview of curcumin as an adjunct therapy and miRNA modulator in breast cancer and highlight the significance of observations for the treatment of cancer therapies.

A single arm prospective feasibility study evaluating wound closure with a unique wearable device that provides intermittent plantar compression and offloading in the treatment of non-healing diabetic foot ulcers. The incidence and economic burden of diabetic foot ulcers continues to rise throughout the world. In this prospective study, a unique device designed to offload the wound, enhance circulation and monitor patient compliance was evaluated for safety and efficacy. The device provides offloading and intermittent plantar compression to improve the pedal flow of oxygenated blood and support wound healing while recording patient use. Ten patients with non-healing diabetic foot ulcers UTgrade 1A/Wagner grade 1 were treated weekly for up to 12 weeks. The primary endpoint was complete wound closure at 12 weeks, and secondary endpoints included healing time, percent area reduction and changes in pain using the visual analogue pain scale. Eight out of ten wounds healed within 12 weeks(80%), and the mean healing time was 41 days(95% CI:24.3-58.3). The percent area reduction was 75(SD:53.9). The baseline visual analogue pain scale was 4.5(2.9) as compared with 3.3(3.4) at end of study. No device-related or serious adverse events were reported. This unique intermediate plantar compression and offloading device may be considered as an alternative for safe and effective for treatment of non-healing diabetic foot ulcers. During treatment, wound healing was significantly accelerated, and pain was improved. Larger randomised controlled trials are underway to validate these early findings.

Factors Associated With the Performance of Extended Colonic Resection vs. Segmental Resection in Early-Onset Colorectal Cancer: A Population-Based Study. OBJECTIVES: Early-onset colorectal cancer (CRC) incidence rates are rising.

RESULTS: Of 2,427 CRC patients, 274 were aged <=50 years. In all, 234 underwent surgery at 53 unique facilities and 6.8% underwent ECR. Statistically significant ECR-associated factors included age <=45 years, polyposis, synchronous/metachronous LS-associated cancers, and IBD. Abnormal microsatellite instability (MSI) was not ECR-associated. ECR was not performed in sporadic CRC.

A super-shedder host may produce up to 10,000 times more pathogens than other infectious hosts. Super-shedders have been reported for multiple human and animal diseases. If their contribution to infection dynamics was linear to the pathogen load, they would dominate infection dynamics. We here focus on quantifying the effect of super-shedders on the spread of infection in natural environments to test if such an effect actually occurs in Mycobacterium avium subspecies paratuberculosis (MAP). We study a case where the infection dynamics and the bacterial load shed by each host at every point in time are known. Using a maximum likelihood approach, we estimate the parameters of a model with multiple transmission routes, including direct contact, indirect contact and a background infection risk. We use longitudinal data from persistent infections (MAP), where infectious individuals have a wide distribution of infectious loads, ranging upward of three orders of magnitude.

Impact of the shedding level on transmission of persistent infections in Mycobacterium avium subspecies paratuberculosis (MAP). Super-shedders are infectious individuals that contribute a disproportionate amount of infectious pathogen load to the environment. A super-shedder host may produce up to 10,000 times more pathogens than other infectious hosts. Super-shedders have been reported for multiple human and animal diseases. If their contribution to infection dynamics was linear to the pathogen load, they would dominate infection dynamics. We here focus on quantifying the effect of super-shedders on the spread of infection in natural environments to test if such an effect actually occurs in Mycobacterium avium subspecies paratuberculosis (MAP). We study a case where the infection dynamics and the bacterial load shed by each host at every point in time are known. Using a maximum likelihood approach, we estimate the parameters of a model with multiple transmission routes, including direct contact, indirect contact and a background infection risk. We use longitudinal data from persistent infections (MAP), where infectious individuals have a wide distribution of infectious loads, ranging upward of three orders of magnitude. We show based on these parameters that the effect of super-shedders for MAP is limited and that the effect of the individual bacterial load is limited and the relationship between bacterial load and the infectiousness is highly concave. A 1000-fold increase in the bacterial contribution is equivalent to up to a 2-3 fold increase in infectiousness.

Manifestations of fasting-induced fatty liver and rapid recovery from steatosis in voles fed lard or flaxseed oil lipids. Long-chain n-3 polyunsaturated fatty acids (PUFA) can have beneficial effects against fat deposition, cardiovascular diseases, and liver steatosis.

The dietary fatty acid composition was manifested in the liver fatty acid signatures. Fasting for 18 h induced macrovesicular steatosis and the liver fat-% increased to 22% independent of the preceding diet.

Food deprivation modified the liver fatty acid signatures to resemble more closely the diets. Fasting reduced the proportions of long-chain n-3 PUFA in both dietary regimes and n-3/n-6 PUFA ratios in the lard-fed voles. Decreases in long-chain n-3 PUFA may promote lipid accumulation by modulating the expression of lipid-metabolizing genes.

Type 2 Myocardial Infarction: CURRENT CONCEPTS AND OUR EXPERIENCE WITH CARDIAC REHABILITATION. BACKGROUND: Type 2 myocardial infarction (T2MI) is commonly encountered in clinical practice, yet little is known about this challenging condition. Outpatient cardiac rehabilitation (CR) is an integral component in the care of patients with MI. However, specific recommendations for CR, information on the feasibility of participation, and outcome measures for patients with T2MI are lacking. CLINICAL CONSIDERATIONS: The frequency of T2MI is markedly variable and depends on the studied population, disease definition, adjudication process, cardiac troponin assays, and cutoff values used to make the diagnosis of T2MI. Clinically, it is difficult to distinguish T2MI from type 1 MI or myocardial injury. Type 2 myocardial infarction occurs due to myocardial oxygen supply-demand mismatch without acute atherothrombotic plaque disruption and is associated with adverse short- and long-term prognoses. Currently, there are substantial gaps in knowledge regarding T2MI and there are no clear guidelines for the optimal management of these patients. SUMMARY: In this article, we present important current concepts surrounding T2MI including the definition, pathophysiology, epidemiology, diagnosis, prognosis, and management. We also discuss referral patterns to CR and participation rates and provide our experience with a case series of 17 patients. Very few patients with T2MI are referred to and participate in CR. Our small case series indicated that patients with T2MI respond favorably to CR and that exercise training following standard guidelines appears safe and is well tolerated.

STUDY DESIGN: The demographic, genetic, and immunologic features of 108 infants with SCID who were treated consecutively at Duke University Medical Center were analyzed. RESULTS: Eighty-nine subjects were boys and 19 were girls; there were 84 white infants, 16 black infants, and 8 Hispanic infants. Forty-nine had X-linked SCID with mutations of common cytokine receptor gamma chain (gamma c), 16 had adenosine deaminase (ADA) deficiency, 8 had Janus kinase 3 (Jak3) deficiency, 21 had unknown autosomal recessive mutations, 1 had reticular dysgenesis, 1 had cartilage hair hypoplasia, and 12 (all boys) had SCID of undetermined type. Deficiency of ADA caused the most profound lymphopenia; gamma c or Jak3 deficiency resulted in the most B cells and fewest natural killer (NK) cells; NK cells and function were highest in autosomal recessive and unknown types of SCID. CONCLUSIONS: Different SCID genotypes are associated with distinctive lymphocyte characteristics. The presence of NK function in ADA-deficient, autosomal recessive, and unknown type SCIDs, and low NK function in a majority of gamma c and Jak3 SCIDs indicates that some molecular lesions affect T, B, and NK cells (gamma c and Jak3), others primarily T cells (ADA deficiency), and others just T and B cells." ], "offsets": [ [ 116, 1595 ] ] } ]

Human severe combined immunodeficiency: genetic, phenotypic, and functional diversity in one hundred eight infants. OBJECTIVE: To determine the relative frequencies of the different genetic forms of severe combined immunodeficiency (SCID) and whether there are distinctive characteristics of the particular genotypes. STUDY DESIGN: The demographic, genetic, and immunologic features of 108 infants with SCID who were treated consecutively at Duke University Medical Center were analyzed. RESULTS: Eighty-nine subjects were boys and 19 were girls; there were 84 white infants, 16 black infants, and 8 Hispanic infants. Forty-nine had X-linked SCID with mutations of common cytokine receptor gamma chain (gamma c), 16 had adenosine deaminase (ADA) deficiency, 8 had Janus kinase 3 (Jak3) deficiency, 21 had unknown autosomal recessive mutations, 1 had reticular dysgenesis, 1 had cartilage hair hypoplasia, and 12 (all boys) had SCID of undetermined type. Deficiency of ADA caused the most profound lymphopenia; gamma c or Jak3 deficiency resulted in the most B cells and fewest natural killer (NK) cells; NK cells and function were highest in autosomal recessive and unknown types of SCID. CONCLUSIONS: Different SCID genotypes are associated with distinctive lymphocyte characteristics. The presence of NK function in ADA-deficient, autosomal recessive, and unknown type SCIDs, and low NK function in a majority of gamma c and Jak3 SCIDs indicates that some molecular lesions affect T, B, and NK cells (gamma c and Jak3), others primarily T cells (ADA deficiency), and others just T and B cells.

Emergence of Ceftolozane-Tazobactam-Resistant Pseudomonas aeruginosa during Treatment Is Mediated by a Single AmpC Structural Mutation. Ceftolozane-tazobactam is a cephalosporin-beta-lactamase inhibitor combination that exhibits potent in vitro activity against Pseudomonas aeruginosa, including strains that are resistant to other beta-lactams. The emergence of ceftolozane-tazobactam resistance among clinical isolates of P. aeruginosa has rarely been described. Here we characterized ceftolozane-tazobactam-resistant P. aeruginosa strains recovered from a patient who was treated with this agent for 6 weeks for a recurrent wound infection. The results showed that the resistance was mediated by a single AmpC structural mutation.

Moreover, SPAK contributes to the regulation of cell volume. Little is known, however, about a role of SPAK in the regulation or organic solutes. The present study thus addressed the influence of SPAK on the peptide transporters PEPT1 and PEPT2. METHODS: To this end, cRNA encoding PEPT1 or PEPT2 were injected into Xenopus laevis oocytes without or with additional injection of cRNA encoding wild-type, SPAK, WNK1 insensitive inactive (T233A)SPAK, constitutively active (T233E)SPAK, and catalytically inactive (D212A)SPAK. Electrogenic peptide (glycine-glycine) transport was determined by dual electrode voltage clamp and PEPT2 protein abundance in the cell membrane by chemiluminescence. Intestinal electrogenic peptide transport was estimated from peptide induced current in Ussing chamber experiments of jejunal segments isolated from gene targeted mice expressing SPAK resistant to WNK-dependent activation (spak(tg/tg)) and respective wild-type mice (spak(+/+)). RESULTS: In PEPT1 and in PEPT2 expressing oocytes, but not in oocytes injected with water, the dipeptide gly-gly (2 mM) generated an inward current, which was significantly decreased following coexpression of SPAK. The effect of SPAK on PEPT1 was mimicked by (T233E)SPAK, but not by (D212A)SPAK or (T233A)SPAK. SPAK decreased maximal peptide induced current of PEPT1. Moreover, SPAK decreased carrier protein abundance in the cell membrane of PEPT2 expressing oocytes. In intestinal segments gly-gly generated a current, which was significantly higher in spak(tg/tg) than in spak(+/+) mice. CONCLUSION: SPAK is a powerful regulator of peptide transporters PEPT1 and PEPT2." ], "offsets": [ [ 67, 1850 ] ] } ]

SPAK dependent regulation of peptide transporters PEPT1 and PEPT2. BACKGROUND/AIMS: SPAK (STE20-related proline/alanine-rich kinase) is a powerful regulator of renal tubular ion transport and blood pressure. Moreover, SPAK contributes to the regulation of cell volume. Little is known, however, about a role of SPAK in the regulation or organic solutes. The present study thus addressed the influence of SPAK on the peptide transporters PEPT1 and PEPT2. METHODS: To this end, cRNA encoding PEPT1 or PEPT2 were injected into Xenopus laevis oocytes without or with additional injection of cRNA encoding wild-type, SPAK, WNK1 insensitive inactive (T233A)SPAK, constitutively active (T233E)SPAK, and catalytically inactive (D212A)SPAK. Electrogenic peptide (glycine-glycine) transport was determined by dual electrode voltage clamp and PEPT2 protein abundance in the cell membrane by chemiluminescence. Intestinal electrogenic peptide transport was estimated from peptide induced current in Ussing chamber experiments of jejunal segments isolated from gene targeted mice expressing SPAK resistant to WNK-dependent activation (spak(tg/tg)) and respective wild-type mice (spak(+/+)). RESULTS: In PEPT1 and in PEPT2 expressing oocytes, but not in oocytes injected with water, the dipeptide gly-gly (2 mM) generated an inward current, which was significantly decreased following coexpression of SPAK. The effect of SPAK on PEPT1 was mimicked by (T233E)SPAK, but not by (D212A)SPAK or (T233A)SPAK. SPAK decreased maximal peptide induced current of PEPT1. Moreover, SPAK decreased carrier protein abundance in the cell membrane of PEPT2 expressing oocytes. In intestinal segments gly-gly generated a current, which was significantly higher in spak(tg/tg) than in spak(+/+) mice. CONCLUSION: SPAK is a powerful regulator of peptide transporters PEPT1 and PEPT2.

The role of neurosteroids and nongenomic effects of progestins in the ventral tegmental area in mediating sexual receptivity of rodents. Progesterone (P(4)) in the ventromedial hypothalamus (VMH) and ventral tegmental (VTA) is important for facilitation of lordosis; however, P(4)'s actions in these brain areas are different. Using lordosis in rodents as in vivo experimental models, we have examined the effects progestins exert in the midbrain and hypothalamus. Localization and blocker studies indicate that P(4)'s actions in the VMH require intracellular progestin receptors (PRs) but in the VTA they do not. Progestins that have rapid, membrane effects, and/or are devoid of affinity for PRs, facilitate lordosis when applied to the VTA. Manipulation of GABA and/or GABA(A)/benzodiazepine receptor complexes (GBRs) in the VTA alter lordosis, which suggests that progestins may interact with GBRs to facilitate receptivity by enhancing the function of GABAergic neurons. Interfering with P(4)'s metabolism to 5 alpha-pregnan-3 alpha-ol-20-one (3 alpha,5 alpha-THP), the most effective endogenous positive modulator of GBRs, or the biosynthesis of the neurosteroid 3 alpha,5 alpha-THP in the VTA attenuates female sexual behavior in rodents. Stimulation of mitochondrial benzodiazepine receptors (MBRs), which enhance neurosteroid production, by infusions of a MBR agonist to the VTA enhances lordosis. 3 alpha,5 alpha-THP is increased in the midbrain of mated > proestrous > diestrous rodents. These data suggest that 3 alpha,5 alpha-THP has a proximate modulatory role on lordosis. In summary, the actions of P(4) in the VTA are different from those in the VMH that involve PRs. In the VTA, P(4) may facilitate lordosis following metabolism to and/or biosynthesis of 3 alpha,5 alpha-THP, which may have subsequent actions at GBRs and/or MBRs to acutely modulate female sexual behavior in rodents.

The synthesized compounds were screened for their in vitro anti-microbial, anti-oxidant, anti-cancer activities and theoretical molecular docking studies. MATERIAL AND METHODS: Structural elucidation of the synthesized compounds was determined on the basis of various spectroscopic methods. Synthesized compounds have been evaluated for their in vitro antimicrobial activity (MIC) against various microbial strains. After the primary screening, synthesised compounds are further studied for anti-oxidant activity using DPPH assay method, anticancer activity against MCF-7 cell line using MTT assay and molecular docking studies. Moreover, molecular dynamics and simulation was done for best compound using GROMACS. RESULTS: A series of 2-chloro-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidine derivatives 6(a-f), 7(a-c) and 8(a-c) were synthesised using solvent-free microwave irradiation technique. Among all the synthesized compounds, compounds 6e (51.35 mug/mL) and 6f (60.14 microg/mL) showed better activity profile against MCF-7 cell line for breast cancer activity. Compounds 6f and 6d have shown potent antibacterial activity against most of the employed strains, especially against S. pneumoniae, B. cerus and S. aureus. Compound 7a (52.21 microg/mL) showed high potential activity for antioxidant using DPPH assay. Molecular docking study showed good binding of these compounds to the active site of ER- alpha with binding energy ranging from -7.12 kcal/mol to -1.21 kcal/mol. Furthermore, molecular dynamics and simulation was conducted for best pose interacted compound 6e with active site of protein to study its stability and behaviour in nanoscale. CONCLUSION: The present research work is intended for facile and efficient green synthesis of various biologically useful potent bio-active molecules from inexpensive and readily available starting substrates under mild reaction condition. These classes of synthesized various heterocyclic compounds holds a great importance to discover newer anti-microbial, anti-oxidant and anti-cancer drugs in future prospects. Further structural modification in these structures will be of interest and may result in compounds having a better therapeutic and biological activity.

Molecular Dynamics and Biological Evaluation of 2-chloro-7-cyclopentyl- 7H-pyrrolo[2,3-d]pyrimidine Derivatives Against Breast Cancer. AIM AND OBJECTIVE: Inspired by the impressive biological properties of pyrrolo[2,3- d]pyrimidine units, the objective of this study was to synthesize some new derivatives of heterocyclic compounds with different substituent's using solvent-free microwave irradiation conditions from readily available starting material. The synthesized compounds were screened for their in vitro anti-microbial, anti-oxidant, anti-cancer activities and theoretical molecular docking studies. MATERIAL AND METHODS: Structural elucidation of the synthesized compounds was determined on the basis of various spectroscopic methods. Synthesized compounds have been evaluated for their in vitro antimicrobial activity (MIC) against various microbial strains. After the primary screening, synthesised compounds are further studied for anti-oxidant activity using DPPH assay method, anticancer activity against MCF-7 cell line using MTT assay and molecular docking studies. Moreover, molecular dynamics and simulation was done for best compound using GROMACS. RESULTS: A series of 2-chloro-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidine derivatives 6(a-f), 7(a-c) and 8(a-c) were synthesised using solvent-free microwave irradiation technique. Among all the synthesized compounds, compounds 6e (51.35 mug/mL) and 6f (60.14 microg/mL) showed better activity profile against MCF-7 cell line for breast cancer activity. Compounds 6f and 6d have shown potent antibacterial activity against most of the employed strains, especially against S. pneumoniae, B. cerus and S. aureus. Compound 7a (52.21 microg/mL) showed high potential activity for antioxidant using DPPH assay. Molecular docking study showed good binding of these compounds to the active site of ER- alpha with binding energy ranging from -7.12 kcal/mol to -1.21 kcal/mol. Furthermore, molecular dynamics and simulation was conducted for best pose interacted compound 6e with active site of protein to study its stability and behaviour in nanoscale. CONCLUSION: The present research work is intended for facile and efficient green synthesis of various biologically useful potent bio-active molecules from inexpensive and readily available starting substrates under mild reaction condition. These classes of synthesized various heterocyclic compounds holds a great importance to discover newer anti-microbial, anti-oxidant and anti-cancer drugs in future prospects. Further structural modification in these structures will be of interest and may result in compounds having a better therapeutic and biological activity. Hence, this efficient green synthetic protocol and biological results of newly synthesized heterocyclic derivatives are found to be interesting lead molecules for bioactivity in the near future. It could be considered for investigation of their mode of action and for further development.

For example, hospitalizations were relatively stable from 2008 to 2011 (approximately 3.9 to 5.2 per 100 patients per year) but decreased in the PCMH group in 2012 (incidence rate ratio, 0.79 [95% CI, 0.69 to 0.90] compared with paper records). Emergency department visits were highest for the PCMH group (16.7 per 100 patients at baseline and 15.4 per 100 patients at the end of the study period) and lowest for the paper group (14.3 per 100 patients at baseline and 12.2 per 100 patients at the end of the study period), but the rate of change did not differ across groups. LIMITATION: Possible unmeasured confounding. CONCLUSION: The PCMH was associated with modest changes in most utilization measures and provided similar quality compared with EHRs and paper records.

Anthrax protective antigen binds to the receptors on the surface of target cells and facilitates the entry of edema factor into these target cells. Edema factor (EF) is an adenylate cyclase that catalyzes the synthesis of cyclic AMP (cAMP) in the cytosol of the host cells. In this study, we examined the requirement of extracellular calcium for anthrax edema toxin-induced toxicity in host cells. The cAMP response generated by edema toxin was analyzed in a variety of cells, including CHO, macrophage-like RAW264.7, human neutrophils, and human lymphocytes. Our investigations reveal that after EF reaches the cell cytosol, a rapid influx of calcium is triggered in the host cell that has a pivotal role in determining the cAMP response of the affected cells. Although the cAMP response generated by edema toxin in different cell types varied in intensity and in the time of initiation, the influx of calcium invariably preceded cAMP accumulation. Agents that blocked the uptake of calcium also inhibited edema toxin-induced accumulation of cAMP in the host cells. This is the first report that demonstrates that edema toxin induces accumulation of cAMP in lymphocytes. By accumulating cAMP, a potent inhibitor of immune cell function, edema toxin may actually be poisoning the immune system and thus facilitating the survival of the bacteria in the host." ], "offsets": [ [ 97, 1539 ] ] } ]

Anthrax edema toxin requires influx of calcium for inducing cyclic AMP toxicity in target cells. The anthrax edema toxin comprises two proteins: protective antigen and edema factor. Anthrax protective antigen binds to the receptors on the surface of target cells and facilitates the entry of edema factor into these target cells. Edema factor (EF) is an adenylate cyclase that catalyzes the synthesis of cyclic AMP (cAMP) in the cytosol of the host cells. In this study, we examined the requirement of extracellular calcium for anthrax edema toxin-induced toxicity in host cells. The cAMP response generated by edema toxin was analyzed in a variety of cells, including CHO, macrophage-like RAW264.7, human neutrophils, and human lymphocytes. Our investigations reveal that after EF reaches the cell cytosol, a rapid influx of calcium is triggered in the host cell that has a pivotal role in determining the cAMP response of the affected cells. Although the cAMP response generated by edema toxin in different cell types varied in intensity and in the time of initiation, the influx of calcium invariably preceded cAMP accumulation. Agents that blocked the uptake of calcium also inhibited edema toxin-induced accumulation of cAMP in the host cells. This is the first report that demonstrates that edema toxin induces accumulation of cAMP in lymphocytes. By accumulating cAMP, a potent inhibitor of immune cell function, edema toxin may actually be poisoning the immune system and thus facilitating the survival of the bacteria in the host.

Paradoxical embolism through a patent foramen ovale from central venous catheter thrombosis: A potential cause of stroke. Paradoxical embolism refers to a potential condition in which an embolus arising from a venous source crosses into the systemic circulation through a right-to-left cardiac shunt causing an arterial embolism. A 39-year-old woman carrier of a central venous catheter (CVC) without evident risk factors for stroke, developed an acute right homonymous hemianopia during hemodialysis. On neuroimaging, an infarct in the territory of the left posterior cerebral artery was demonstrated. Transesophageal echocardiography revealed a patent foramen ovale (PFO) and a large fluctuating thrombus in the right atrium on the tip of the CVC, thus allowing a diagnosis of ischemic stroke from paradoxical embolism. Oral anticoagulation therapy was started and the PFO was closed. This case emphasizes the potential risk of paradoxical embolism in patients with CVCs and PFO. This condition should be prevented and identified in patients with specific risk factors, such as long-term catheterization and hemodialysis.
