Flow cytometry of lesional skin enhances the evaluation of cutaneous B-cell lymphomas. BACKGROUND: Cutaneous B-cell lymphoproliferative lesions can pose diagnostic challenges. This study investigates the utlility of flow cytometry in 42 cases of suspected cutaneous B-cell lymphoma. METHODS: All available cases were reviewed [World Health Organization-European Organization for Research and Treatment of Cancer (WHO-EORTC) classification]. Flow cytometry, immunohistochemistry and polymerase chain reaction-immunoglobulin H (PCR-IgH) analysis of blood and/or lesional skin were performed on primary cutaneous B-cell lymphoma (pcBCL, 17 cases), secondary cutaneous BCL (scBCL, 8 cases) and atypical lymphoid hyperplasia (ALH, 17 cases). RESULTS: Flow cytometry of skin detected a B-cell clone in 3/13 cases of ALH, 8/8 cases of pcBCL and 4/4 cases of scBCL, while PCR detected a clone in 3/14 cases of ALH, 4/15 cases of pcBCL and 6/8 cases of scBCL. Of eight cases of pcBCL analyzed by both methods, all eight were positive by flow while only three were positive by PCR. All cases positive by PCR were also positive by flow. Of five cases with both flow and light chain immunohistochemistry, all five showed light chain restriction by flow, while only two were positive by immunohistochemistry. CONCLUSION: Flow cytometry is more sensitive than PCR in detecting B-cell lymphoproliferative disorders (12/12 cases, 100% vs. 10/23 cases, 43%; p < 0.001). Furthermore, flow cytometry complements immunohistochemistry in the detection of light chain restriction.

Prevalence and risk factors of erectile dysfunction in three cities of China: a community-based study. AIM: To determine the age-adjusted prevalence of erectile dysfunction (ED) in 3 big cities of China and to explore its potential sociodemographic, medical and lifestyle correlates. METHODS: A cross-sectional, population-based survey was conducted in three cities of China. Structured questionnaires were administered to 2 226 men, aged 20 - 86 years, by trained interviewers. RESULTS: The age-adjusted prevalence of ED was 28.34 % (mild 15.99 %, moderate 7.14 %, severe 5.21 %). In the men above 40, the prevalence was 40.2 %. Age was positively correlated with ED (P<0.01). Education was negatively correlated with ED (P<0.01). Spouse companionship, living condition were positively correlated with ED (P<0.01). Histories of cardiovascular disease, diabetes, and hyperlipidemia were positively correlated with ED (P<0.01). Cigarette smoking was not correlated with ED (P>0.05), while the cigarette consumption and duration were positively correlated with ED (P<0.01). Alcohol drinking is negatively correlated with ED (P<0.01). The duration of drinking was positively correlated with ED (P<0.01). Weekly alcohol consumption was not correlated with ED (P>0.05). CONCLUSION: The prevalence of ED increased with age. Cardiovascular disease, diabetes and hyperlipidemia were positively correlated with the increased prevalence. Sociodemographic and lifestyle factors, such as education, spouse companionship, living condition, cigarette and alcohol consumption or duration also have association with the prevalence of ED.

Treatment of the postwarming oocytes with 10 muM Y-27632 for 2 h resulted in the significantly higher oocyte survival rate before IVF as well as higher cleavage rate and blastocyst formation rate. Quality analysis of the resultant blastocysts in terms of total cell number and apoptotic cell ratio also showed the positive effect of the Y-27632 treatment. Time-dependent change in mitochondrial activity of the vitrified-warmed oocytes was not influenced by ROCK inhibition during the period of recovery culture. However, the ability of ooplasm to support single-aster formation was improved by the ROCK inhibition. Thus, inhibition of ROCK activity in vitrified-warmed bovine oocytes during a short-term recovery culture can lead to higher developmental competence, probably due to decreased apoptosis and normalized function of the microtubule-organizing center." ], "offsets": [ [ 92, 1470 ] ] } ]

Rescue of vitrified-warmed bovine oocytes with rho-associated coiled-coil kinase inhibitor. Cryotolerance of matured bovine oocytes is not fully practical even though a promising vitrification procedure with a ultrarapid cooling rate was applied. The present study was conducted to investigate whether recovery culture of vitrified-warmed bovine oocytes with an inhibitor (Y-27632) of Rho-associated coiled-coil kinase (ROCK) can improve the developmental potential after in vitro fertilization (IVF) and in vitro culture.

The hindbrain (brainstem) of all vertebrates follows a segmental developmental strategy and has been the focus of intense study not only for its intrinsic interest but also as a model for how more complex regions of the brain are patterned. Segmentation ultimately serves to organize the development of neuronal populations and their projections, and regional diversity is achieved through each segment having its own identity.

The authors of this study analyzed immunohistochemical distributions of Types I, II, III and VI collagen, in situ localization of apoptotic disc cells, and tartrate-resistant acid phosphatase localization. OBJECTIVES: To quantify the incidence of apoptotic cell death in the anulus; examine the collagen distribution in the pericellular, territorial, and interterritorial matrix; examine matrix cell degeneration; and compare diseased tissue with normal tissue from control individuals. SUMMARY OF THE BACKGROUND DATA: Previous studies of disc histopathology have focused on extracellular matrix morphology and on biochemical synthetic and degenerative changes, but little is understood about the cell populations within the disc that are responsible for these changes. METHODS: In this study light microscopy, immunohistochemistry, enzyme histochemistry, and in situ hybridization were used to examine 33 patient and 39 control specimens of human anulus obtained either via surgical procedures or from donors to the Cooperative Human Tissue Network. RESULTS: The high incidence of apoptotic cell death was significantly greater in the control group (73.1 +/- 5.1% [mean +/- SEM]; n = 20) than among surgical specimens (53.5 +/- 5.6%; n = 20; P < 0.001); this was probably a result of the significantly greater average age in the control population (57.2 +/- 3.1 years) compared with that in the patient population (44.3 +/- 3.2 years; P < 0.001). Immunohistochemistry yielded findings that led to an expanded appreciation of the greatly modified extracellular domains that surrounded disc cells during aging and degeneration in both study groups. Enzyme histochemistry revealed the presence of tartrate-resistant acid phosphatase activity in human disc cells. CONCLUSIONS: These findings reveal that there is a high incidence of apoptosis in the intervertebral disc. Surviving cells are not synthetically inactive but are, rather, producing inappropriate matrix products during aging and degeneration. In certain instances it appears that the matrix surrounding the cell may form an isolation barrier, which may influence individual cell activity and intercellular communication. These results point to the need to 1) more fully understand the cause of disc cell death via apoptosis and to determine whether this programmed cell death can be reversed or halted, and 2) more fully understand the dynamic relation between disc cells and the surrounding extracellular matrix, which they produce and remodel. The factors regulating extracellular matrix-disc cell homeostasis in the disc are unknown, as is the relation between extracellular matrix and disc cell functional modulation. The morphologic findings of this study suggest that these issues are important considerations in disc cell biology. The identification of tartrate-resistant acid phosphatase activity in disc cells allows for a new area of study of disc extracellular matrix remodelling. In summary, these new perspectives provide new parameters with which to assess disc cell health and function." ], "offsets": [ [ 124, 3382 ] ] } ]

Analysis of aging and degeneration of the human intervertebral disc. Comparison of surgical specimens with normal controls. STUDY DESIGN: A prospective analysis of 33 control and 39 surgical human lumbar disc specimens from the anulus was undertaken to assess disc cell extracellular matrix production and cell function. The authors of this study analyzed immunohistochemical distributions of Types I, II, III and VI collagen, in situ localization of apoptotic disc cells, and tartrate-resistant acid phosphatase localization. OBJECTIVES: To quantify the incidence of apoptotic cell death in the anulus; examine the collagen distribution in the pericellular, territorial, and interterritorial matrix; examine matrix cell degeneration; and compare diseased tissue with normal tissue from control individuals. SUMMARY OF THE BACKGROUND DATA: Previous studies of disc histopathology have focused on extracellular matrix morphology and on biochemical synthetic and degenerative changes, but little is understood about the cell populations within the disc that are responsible for these changes. METHODS: In this study light microscopy, immunohistochemistry, enzyme histochemistry, and in situ hybridization were used to examine 33 patient and 39 control specimens of human anulus obtained either via surgical procedures or from donors to the Cooperative Human Tissue Network.

Although the high concentration of PCr in glycolytic fast-twitch fibers supports the role of PCr as a buffer of ATP, the primary importance of the creatine kinase (CK) reaction may in fact be to counteract large increases in ADP, which could otherwise inhibit cellular ATPase-mediated systems. A primary role for CK in the maintenance of ADP homeostasis may explain why, in many conditions, there is an inverse relationship between PCr and muscle contractility but not between ATP and muscle contractility.

The presence of CK, structurally bound in close vicinity to the sites of ATP utilization, will reduce the amplitude and duration of the ADP spikes through PCr-mediated phosphotransfer. When PCr is reduced, the efficiency of CK as an ATP buffer will be reduced and the changes in ADP will become more prominent. The presence of ADP spikes is supported by the finding that other processes known to be activated by ADP (i.e. AMP deamination and glycolysis) are stimulated during exercise but not during anoxia, despite the same low global energy state.

Spartin: At the crossroad between ubiquitination and metabolism in cancer. SPART is a gene coding for a multifunctional protein called spartin, localized in various organelles of human cells. Mutations in the coding region are responsible for a hereditary form of spastic paraplegia called Troyer syndrome while the epigenetic silencing has been demonstrated for some types of tumors. The main functions of this gene are associated to endosomic trafficking and receptor degradation, microtubule interaction, cytokinesis, fatty acids and oxidative metabolism. Spartin has been shown to be a target regulated by STAT3 and localizes also at the level of the mitochondrial outer membrane, where it forms part of a complex maintaining the integrity of the membrane potential. The most recent evidences report a downregulation of spartin in tumor tissues when compared to adjacent normal samples. This intriguing evidence supports further research aimed at clarifying the role of this protein in cancer development and metabolism.

However, owing to the viscoelastic properties of respiratory tissues, Rrs and Ers exhibit frequency dependence below 2 Hz. The goal of this study was to investigate the bias and statistical accuracy of various time-domain approaches with respect to model properties, as well as the estimated impedance spectra. Particular emphasis was placed on establishing the tracking capability using a standard step ventilation. A simulation study compared continuous-time versus discrete-time approaches for both the single-compartment and two-compartment models. Data were acquired in four healthy humans and two dogs before and after induced severe pulmonary edema while applying sinusoidal and standard ventilator forcing. Rrs and Ers were estimated either by the standard Fast Fourier Transform (FFT) approach or by a time-domain least square estimation. Results show that the continuous-time model form produced the least bias and smallest parameter uncertainty for a single-compartment analysis and is quite amenable for reliable on-line tracking. The discrete-time approach exhibits large uncertainty and bias, particularly with increasing noise in the flow data. In humans, the time-domain approach produced smooth estimates of Rrs and Ers spectra, but they were statistically unreliable at the lower frequencies. In dogs, both the FFT and time-domain analysis produced reliable and stable estimates for Rrs or Ers spectra for frequencies out to 2 Hz in all conditions.

Assessment of time-domain analyses for estimation of low-frequency respiratory mechanical properties and impedance spectra. Time-domain estimation has been invoked for tracking of respiratory mechanical properties using primarily a simple single-compartment model containing a series resistance (Rrs) and elastance (Ers). However, owing to the viscoelastic properties of respiratory tissues, Rrs and Ers exhibit frequency dependence below 2 Hz. The goal of this study was to investigate the bias and statistical accuracy of various time-domain approaches with respect to model properties, as well as the estimated impedance spectra. Particular emphasis was placed on establishing the tracking capability using a standard step ventilation. A simulation study compared continuous-time versus discrete-time approaches for both the single-compartment and two-compartment models. Data were acquired in four healthy humans and two dogs before and after induced severe pulmonary edema while applying sinusoidal and standard ventilator forcing. Rrs and Ers were estimated either by the standard Fast Fourier Transform (FFT) approach or by a time-domain least square estimation. Results show that the continuous-time model form produced the least bias and smallest parameter uncertainty for a single-compartment analysis and is quite amenable for reliable on-line tracking. The discrete-time approach exhibits large uncertainty and bias, particularly with increasing noise in the flow data. In humans, the time-domain approach produced smooth estimates of Rrs and Ers spectra, but they were statistically unreliable at the lower frequencies. In dogs, both the FFT and time-domain analysis produced reliable and stable estimates for Rrs or Ers spectra for frequencies out to 2 Hz in all conditions. Nevertheless, obtaining stable on-line parameter estimates for the two-compartment viscoelastic models remained difficult. We conclude that time-domain analysis of respiratory mechanics should invoke a continuous-time model form.

Changes in macroscopic viscosity do not affect the release of aroma aldehydes from a pectinaceous food model system of low sucrose content. The effects of pectin and viscosity on the release of a systematic series of aldehydes (alkanals, methyl-alkanals, alkenals, and alkandienals) were studied in a food model system of low sucrose content (10% w/w). The viscosity was varied by adding different amounts of Ca(2+) (0, 13.5, and 27 mg/g pectin) to the model system of constant pectin concentration (0.4% w/w). Air-liquid partition coefficients, K (37 degrees C), of the aroma compounds were determined in aqueous and pectin-thickened solutions. Diffusivities of the aroma compounds in water and three pectin-thickened solutions were estimated from release rate constants that were obtained via timed collection of volatiles in the gas phase and quantifications by dynamic headspace-gas chromatography.

The three kinases differ in their abilities to phosphorylate substrates such as histones (calf thymus), casein, and S. cerevisiae ribosomes; two of the kinases showed increased activity in the presence of cyclic adenosine 3',5'-monophosphate when histones and 40S ribosomal subunits were used as substrates. The protein kinases catalyzed phosphorylation of certain proteins of the 40S and 60S ribosomal subunits, and 80S ribosomes in vitro. Nine proteins of the 80S ribosome, seven proteins of the 40S subunit, and eleven of the 60S subunit were phosphorylated; different proteins were modified to various extents when different kinases were used. We have identified several proteins of 40S and 60S ribosomal subunits which are not available to the kinases in the 80S particles. Ribosomes isolated from S. cerevisiae cells growing in logarithmic phase of growth were found to contain a number of phosphorylated proteins. Studies by two-dimensional polyacrylamide gel electrophoresis indicated that the ribosomal proteins phosphorylated in vivo correspond with those phosphorylated in vitro. The relationship of in vivo phsophorylation of ribosomes to the growth and physiology of S. cerevisiae is not known.

Autophagy-deficient mice develop multiple liver tumors. Autophagy is a major pathway for degradation of cytoplasmic proteins and organelles, and has been implicated in tumor suppression. Here, we report that mice with systemic mosaic deletion of Atg5 and liver-specific Atg7-/- mice develop benign liver adenomas. These tumor cells originate autophagy-deficient hepatocytes and show mitochondrial swelling, p62 accumulation, and oxidative stress and genomic damage responses. The size of the Atg7-/- liver tumors is reduced by simultaneous deletion of p62. These results suggest that autophagy is important for the suppression of spontaneous tumorigenesis through a cell-intrinsic mechanism, particularly in the liver, and that p62 accumulation contributes to tumor progression.

The Prognostic Value of Varying Definitions of Positive Resection Margin in Patients with Colorectal Cancer Liver Metastases. BACKGROUND: Varying definitions of resection margin clearance are currently employed among patients with colorectal cancer liver metastases (CRLM). Specifically, a microscopically positive margin (R1) has alternatively been equated with an involved margin (margin width = 0 mm) or a margin width < 1 mm. Consequently, patients with a margin width of 0-1 mm (sub-mm) are inconsistently classified in either the R0 or R1 categories, thus obscuring the prognostic implications of sub-mm margins. METHODS: Six hundred thirty-three patients who underwent resection of CRLM were identified. Both R1 definitions were alternatively employed and multivariable analysis was used to determine the predictive power of each definition, as well as the prognostic implications of a sub-mm margin. RESULTS: Five hundred thirty-nine (85.2%) patients had a margin width >= 1 mm, 42 had a sub-mm margin width, and 52 had an involved margin (0 mm). A margin width >= 1 mm was associated with improved survival vs. a sub-mm margin (65 vs. 36 months; P = 0.03) or an involved margin (65 vs. 33 months; P < 0.001). No significant difference in survival was detected between patients with involved vs. sub-mm margins (P = 0.31). A sub-mm margin and an involved margin were both independent predictors of worse OS (HR 1.66, 1.04-2.67; P = 0.04, and HR 2.14, 1.46-3.16; P < 0.001, respectively) in multivariable analysis. Importantly, after combining the two definitions, patients with either an involved margin or a sub-mm margin were associated with worse OS in multivariable analysis (HR 1.94, 1.41-2.65; P < 0.001). CONCLUSIONS: Patients with involved or sub-mm margins demonstrated a similar inferior OS vs. patients with a margin width > 1 mm. Consequently, a uniform definition of R1 as a margin width < 1 mm should perhaps be employed by future studies.

Substituted heterocyclic naphthalene diimides with unexpected acidity. Synthesis, properties, and reactivity. Naphthalene bisimides (NDIs) with a heterocyclic 1,4-dihydro-2,3-pyrazinedione moiety have been synthesized from both 2,6-dibromonaphthalene and 2,3,6,7-tetrabromonaphthalene bisanhydrides by means of a stepwise protocol including imidization, nucleophilic displacement of the bromine atoms by ethane-1,2-diamine, in situ reductive dehalogenation, and further oxidation. These heterocycles (R = n-pentyl, cyclohexyl) are yellow dyes with green emission in organic solvent, where the acid form dominates. The orange nonfluorescent conjugate base can be generated quantitatively by CH(3)COONBu(4) addition in DMSO, where it exhibits a pK(a) = 7.63. The conjugate base becomes the only detectable species (by UV-vis spectroscopy), in water solution, even under acid conditions (pH 1). In aqueous DMSO the acid/base equilibrium is a function of the DMSO/water ratio. The unexpected acidity of these heterocyclic NDIs, which justifies the reactivity with CH(2)N(2), has been rationalized by DFT computational means [PBE0/6-31+G(d,p)] in aqueous solvent (PCM models) as a result of a strong specific solvation effect, modeled by the inclusion of three water molecules.

Rapamycin at subimmunosuppressive levels inhibits mesangial cell proliferation and extracellular matrix production. In view of its proven antiproliferative effects, rapamycin offers potential in the treatment of mesangioproliferative disease.

Therefore, we explored the effects and mechanism of action of low levels of rapamycin on mesangial cell proliferation.

Influence of stimulation of the medial hypothalamus on the interaction of neurons of the rabbit neocortex. The interaction of neurons of the visual and sensory motor areas of the neocortex of the rabbit before and after stimulation of some medial nuclei of the hypothalamus was investigated by plotting cross- and autocorrelation histograms. Stimulation through bipolar electrodes using bursts of biphasic pulses at a frequency of 100 Hz, current strength 50-200 microA, led to the appearance in freely behaving rabbits of the reaction of avoidance of the place of stimulation. Following stimulation, as compared with resting wakefulness, the number of pairs of neurons functioning in correlation increased to 45%; at the same time, discharges of neurons of the sensory motor area ran ahead of discharges of visual neurons in the pairs up to 120 msec; the periodicity of the coupled discharges was mainly in the theta frequency range. A conclusion regarding the reflection of defense motivation in certain indices of the interaction of the cortical cells in the presence of a tonic conditioned reflex is reached on the basis of a comparison of the interaction of neurons following stimulation of the medial hypothalamus and the midbrain reticular formation, in the intersignal periods during the development of a defense conditioned reflex as well.

Calcineurin, a Ca-dependent phosphatase critically involved in synaptic plasticity, is activated after isoflurane exposure, but its role in the neurological response to anesthesia is unclear. METHODS: We investigated the effect of chronic calcineurin inhibition on postanesthetic cognitive function. Mice were treated with 30 minutes of isoflurane anesthesia during a chronic cyclosporine A regimen. Behavioral end points during the perianesthesia period were quantified. Visuospatial learning was assessed with the water radial arm maze. Total and biotinylated surface protein expression of the alpha5beta3gamma2 gamma-aminobutyric acid (GABA) type A receptors was measured.

A modern approach to prevention and treatment of oral bleeding in patients with hepatocellular disease. Dental treatment for patients with hepatocellular disease constitutes a very complex problem because of their severe bleeding tendency. It seems that bleeding from the oral structures follows organ-specific patterns. The use of systemically administered antifibrinolytic agents, together with the local use of Gelfoam, cyanoacrylate spray, and intraligamentary anesthesia make possible bleeding-inducing procedures without exaggerated hemorrhage. This approach avoids the need for transfusion and hospitalization for dental treatment, making such treatment cheaper and more accessible.

Accumulation of NACP/alpha-synuclein in lewy body disease and multiple system atrophy. OBJECTIVES: NACP/alpha-synuclein is an aetiological gene product in familial Parkinson's disease. To clarify the pathological role of NACP/alpha-synuclein in sporadic Parkinson's disease and other related disorders including diffuse Lewy body disease (DLBD) and multiple system atrophy (MSA), paraffin sections were examined immunocytochemically using anti-NACP/alpha-synuclein antibodies. METHODS: A total of 58 necropsied brains, from seven patients with Parkinson's disease, five with DLBD, six with MSA, 12 with Alzheimer's disease, one with Down's syndrome, one with amyotrophic lateral sclerosis (ALS), three with ALS and dementia, one with Huntington's disease, two with progressive supranuclear palsy (PSP), one with Pick's disease, one with myotonic dystrophy, and three with late cerebellar cortical atrophy (LCCA), and 15 elderly normal controls were examined. RESULTS: In addition to immunoreactive Lewy bodies, widespread accumulation of NACP/alpha-synuclein was found in neurons and astrocytes from the brainstem and basal ganglia to the cerebral cortices in Parkinson's disease/DLBD. NACP/alpha-synuclein accumulates in oligodendrocytes from the spinal cord, the brain stem to the cerebellar white matter, and inferior olivary neurons in MSA. These widespread accumulations were not seen in other types of dementia or spinocerebellar ataxia. CONCLUSION: Completely different types of NACP/alpha-synuclein accumulation in Parkinson's disease/DLBD and MSA suggest that accumulation is a major step in the pathological cascade of both diseases and provides novel strategies for the development of therapies.

After tracheal intubation, the isoflurane was inhalated to maintain anesthesia. The concentration of isoflurane was elevated to reduce MAP by 30%-40% during dissection and occlusion of tumor and the level maintained for 30-45 min.

In the context of chronic liver disease (CLD), insults that drive hepatic inflammation and fibrogenesis (alcohol, fat) can drastically increase intestinal permeability, hence flooding the liver with gut-derived microbiota. Consequently, this may result in exacerbated liver inflammation and fibrosis through activation of liver-resident Kupffer and stellate cells by bacterial, viral, and fungal antigens transported to the liver via the portal vein.

The Role of Gut-Derived Microbial Antigens on Liver Fibrosis Initiation and Progression. Intestinal dysbiosis has recently become known as an important driver of gastrointestinal and liver disease. It remains poorly understood, however, how gastrointestinal microbes bypass the intestinal mucosa and enter systemic circulation to enact an inflammatory immune response. In the context of chronic liver disease (CLD), insults that drive hepatic inflammation and fibrogenesis (alcohol, fat) can drastically increase intestinal permeability, hence flooding the liver with gut-derived microbiota. Consequently, this may result in exacerbated liver inflammation and fibrosis through activation of liver-resident Kupffer and stellate cells by bacterial, viral, and fungal antigens transported to the liver via the portal vein. This review summarizes the current understanding of microbial translocation in CLD, the cell-specific hepatic response to intestinal antigens, and how this drives the development and progression of hepatic inflammation and fibrosis. Further, we reviewed current and future therapies targeting intestinal permeability and the associated, potentially harmful anti-microbial immune response with respect to their potential in terms of limiting the development and progression of liver fibrosis and end-stage cirrhosis.

The heterogeneous photo-Fenton reaction using goethite as catalyst. In the present work the degradation of 2-chlorophenol (2-CP) used as model compound, applying the Heterogeneous photo-Fenton reaction, was studied. Small particles of goethite or iron oxyhydroxide were used as a source of iron. The influence of catalyst loading, radiation intensity and the molar ratio between hydrogen peroxide and contaminant were examined. Improvement by illumination is highly significant. During the progress of 2-CP degradation, the reaction shows an unusual acceleration. This autocatalytic comportment, with stronger tendencies at higher temperatures, implies a completely different behaviour from the one typically expected. The autocatalytic performance is successfully explained by the joint action of two factors: (i) the evolution of the available iron in the homogeneous phase during the course of the reaction and (ii) the autocatalytic contribution of some of the reaction intermediates in the iron cycle. The small iron concentration leaching into the solution is produced by two typical liquid medium - solid goethite surface dissolution processes. A reaction mechanism has been proposed and, in a first stage, parameters have been obtained for the dark reaction. In a second step, the complete data for the irradiated operation were obtained.

This study aims to clarify the effect of metabolic nuclear receptors on Lgr5 + cell fate in liver. Methods: We performed cell experiments with primary hepatocytes, Hep 1-6, Hep G2, and Huh 7 cells, and animal studies with wild-type (WT), farnesoid X receptor (FXR) knockout mice, peroxisome proliferator-activated receptor alpha (PPARalpha) knockout mice and Lgr5-CreERT2; Rosa26-mTmG mice. GW4064 and CDCA were used to activate FXR. And GW7647 or Wy14643 was used for PPARalpha activation. Regulation of Lgr5 by FXR and PPARalpha was determined by QRT-PCR, western blot (WB) and RNAscope in situ hybridization (ISH) and immunofluorescence (IF), luciferase reporter assay, electrophoretic mobility shift assay (EMSA) and chromatin immunoprecipitation (ChIP). Diethyl 1,4-dihydro-2,4,6-trimethyl-3,5-pyridinedicarboxylate (DDC) diet was used to induce liver injury. Results: Pharmacologic activation of FXR induced Lgr5 expression, whereas activation of PPARalpha suppressed Lgr5 expression. Furthermore, FXR and PPARalpha competed for binding to shared site on Lgr5 promoter with opposite transcriptional outputs. DDC diet triggered the transition of Lgr5 + cells from resting state to proliferation. FXR activation enhanced Lgr5 + cell expansion mainly by symmetric cell division, but PPARalpha activation prevented Lgr5 + cell proliferation along with asymmetric cell division.

In this article, the effects of prescription drug coverage on use are analyzed for beneficiaries of a large retiree health benefit fund in a quasi-experiment comparing new and established enrollees. Newer enrollees show an 18-percentage point greater increase in prescription drug expenditures per capita than established enrollees during the 3-year period following enrollment. This differential is interpreted as the insurance effect of prescription coverage. The impact was greater among high-cost drugs than among low-cost drugs, and also greater among low users of prescription drugs than among high users. No clear patterns were discerned across therapeutic categories.

Dominance rank, cortisol concentrations, and reproductive maturation in male rhesus macaques. Among adolescent male rhesus macaques, Macaca mulatta, the highest ranking individual within a cohort has higher testosterone concentrations at a younger age, earlier in the mating season, and for a longer duration than his lower ranking conspecifics. We sought to determine whether such a rank-related pattern of reproductive maturation could be a function of differences in glucocorticoid levels. A 2-yr longitudinal study of a cohort of adolescent males living in a heterosexual group in a one acre outdoor enclosure revealed no differences in cortisol concentrations between high and low status males. Cortisol was not inversely correlated with testosterone in either adolescent or adult males. Young pubescent males had increases in cortisol levels coincident with maturation, while older adolescent males had cortisol concentrations comparable to those of adult males. Low ranking males tended to have more variable cortisol concentrations across time. We conclude that cortisol concentrations are not a function of dominance status and that the timing of reproductive maturation in male rhesus macaques is independent of cortisol concentrations.

Whip spiders (Amblypygi) become water-repellent by a colloidal secretion that self-assembles into hierarchical microstructures. BACKGROUND: Among both plants and arthropods, super-hydrophobic surfaces have evolved that enable self-cleaning, locomotion on water surfaces, or plastron respiration. Super-hydrophobicity is achieved by a combination of non-polar substances and complex micro- and nano-structures, usually acquired by growing processes or the deposition of powder-like materials. RESULTS: Here we report on a multi-phasic secretion in whip spiders (Arachnida, Amblypygi), which externally forms durable, hierarchical microstructures on the basically smooth cuticle. The solidified secretion crust makes the previously highly wettable cuticle super-hydrophobic. We describe the ultrastructure of secretory cells, and the maturation and secretion of the different products involved. CONCLUSION: Whip spiders represent intriguing objects of study for revealing the mechanisms of the formation of complex microstructures in non-living systems. Understanding the physical and chemical processes involved may, further, be of interest for bio-inspired design of functional surface coatings.

Genistein is a natural inhibitor of hexose and dehydroascorbic acid transport through the glucose transporter, GLUT1. Genistein is a dietary-derived plant product that inhibits the activity of protein-tyrosine kinases. We show here that it is a potent inhibitor of the mammalian facilitative hexose transporter GLUT1. In human HL-60 cells, which express GLUT1, genistein inhibited the transport of dehydroascorbic acid, deoxyglucose, and methylglucose in a dose-dependent manner. Transport was not affected by daidzein, an inactive genistein analog that does not inhibit protein-tyrosine kinase activity, or by the general protein kinase inhibitor staurosporine. Genistein inhibited the uptake of deoxyglucose and dehydroascorbic acid in Chinese hamster ovary (CHO) cells overexpressing GLUT1 in a similar dose-dependent manner.

Correlates of serum lycopene in older women. Experimental and epidemiological evidence suggests that lycopene, a predominant carotenoid found in human serum, may reduce the risk of certain cancers. We examined the association of dietary, physiological, and other factors with serum lycopene concentrations in a subsample of 946 postmenopausal women participating in the Women's Health Initiative. Pearson partial correlation coefficients and linear regression coefficients were calculated after adjustment for age, ethnicity, and serum low-density-lipoprotein (LDL) cholesterol. Serum lycopene was correlated with serum LDL cholesterol (r = 0.23) and dietary lycopene (r = 0.17, both p < 0.001). Individual food items found to be correlated with serum lycopene after adjustment included fresh tomatoes or tomato juice (r = 0.11), cooked tomatoes, tomato sauce, or salsa (r = 0.17), and spaghetti with meat sauce (r = 0.19, all p < 0.01).

Cisternal CSF cytologic examination should be considered in patients suspected of having leptomeningeal metastasis if lumbar CSF is nondiagnostic.

The Evolution of the Human Hand From an Anthropologic Perspective. Coupled with the developing brain and freed from ambulatory responsibilities, the human hand has experienced osteologic and myologic changes throughout evolutionary time that have permitted manipulative capacities of social, functional, and cultural importance in modern-day human life.

Resolution of the phosphoenolpyruvate: fructose phosphotransferase system of Escherichia coli into two components: enzyme IIfructose and fructose-induced HPr-like protein (FPr). A protein that substitutes for histidine-containing protein (HPr) in the phosphoenolpyruvate, fructose phosphotransferase system has been found in Escherichia coli grown on fructose. The impure preparation of the fructose-induced HPr-like protein (FPr) appears to be an extrinsic membrane protein which differs from HPr on the basis of its apparent molecular weight (45 000 vs. 9600, respectively), its affinity for DEAE-cellulose and its ability to promote sugar phosphorylation which is specific for fructose, rather than for glucose.

METHODS: Isometric contractions and relaxations in isolated rabbit strip were observed in response to changes in oxygen tension and effect of various drugs was noted on them. RESULTS: Change in oxygen tension from high [pO2 =(618.9 +/- 0.4) mmHg; 1 mmHg = 133.3 Pa] to low [pO2 = (117.6+/-0.6) mmHg] was observed to convert the relaxant effect of acetylcholine (ACh), in rabbit aorta precontracted with phenylephrine, to a marked contractile response. As the aerating gas was changed from 100 % to 20 % oxygen, the relaxant effect to ACh, recorded every hour, gradually decreased till it gave way to a significant contraction over a period of 3.5 h. On reoxygenation the relaxant effect to ACh was irreversibly inhibited, however, the relaxant effect to SOD (40 kU/L) was not. The per se constrictor effect to ACh was abolished by endothelium removal and by combination of SOD (40 kU/L), catalase (1000 kU/L) and indomethacin (1 x 10(-5 ) mol/L).

CONCLUSION: The above results implicate that some functional change occurs in the endothelium exposed to low p(O2) such that the stimulated release of endothelium-derived relaxing factor (EDRF) in response to ACh is completely and irreversibly inhibited, whereas, the basally released EDRF in response to SOD is not and marked increase in prostaglandin synthesis is stimulated." ], "offsets": [ [ 125, 1825 ] ] } ]

By scanning electron microscopy we followed: the platelet morphology and aggregation, the macrophage (M) morphology and the lymphocyte (T, B) count and structure in 11 patients with AMI and in 18 patients with unstable angina (UA). Generally, in the patients with AMI, most of the platelets presented relatively frequent (42.5%) or very frequent pseudopodia (35.27%) and the network of surface extensions was associated with several huge platelet aggregates in 6 patients. The mean lymphocyte count was: T = 40.36 +/- 23.95%; B = 28.09 +/- 7.38%; M = 31.54 +/- 21.25%. In the patients with unstable angina the proportion of platelets with pseudopodia was more reduced, namely, that of platelets with relatively frequent pseudopodia was 33.8% and with very frequent pseudopodia was 27.8%. The mean lymphocyte count was: T = 40.30 +/- 20.24%; B = 34.6 +/- 14.39%; M = 25 +/- 10.50%. These data indicate that platelet changes and the formation of aggregates can be an important factor in the occurrence of AMI. The change of immunocompetent cell count in both groups of coronary patients suggests the association of an immunologic process in coronary atherosclerosis.

Biomimetic Organic-Inorganic Hybrid Membranes for Removal of Fluoride Ions. Carbon nanofibers (CaNFs) exhibit promising applications in the fields of environmental science and nanotechnology, and self-assembled peptide nanofibers (PNFs) are useful for the biomimetic synthesis of organic-inorganic hybrid nanomaterials and the fabrication of functional hybrid membranes for the removal of various pollutants from water. In this work, we report the biomimetic synthesis of hybrid nanomaterials by the interweaving of CaNFs and PNFs.
