PROBLEM TO BE SOLVED: To efficiently obtain a thin flaky glass having a smooth surface and high transparency by applying a sol contg. an organometallic compd.-base polymer on a metallic substrate, drying and contracting the sol to release a gel and heating the gel at a high temp. SOLUTION: A sol contg. a polymer resulting from an organometallic compd. (e.g. Si methoxide) and having 3,000-1,000,000 mol.wt. is prepared. The sol is then applied on a substrate having <=50nm surface roughness Ra, heat-treated at a high temp. in an oxygen-contg. atmosphere and with the outermost surface made of a metal to form a sol film. The sol film is then dried, contracted and released from the substrate to obtain a flaky gel. The flaky gel is then heated at a high temp. to obtain a flaky glass having 0.1-1μm mean thickness, 5-150 aspect ratio and <=50nm surface roughness Ra and transmitting >=80% of the light of 550nm wavelength. This flake is appropriately used to produce a facing material, etc.
The propensity to metastasize is the most important prognostic indicator for solid cancers. New insights into the mechanisms of early carcinogenesis have revealed micrometastases are generated far earlier than previously thought. Evidence supports a synergistic relationship between vascular and lymphatic seeding which can occur before there is clinical evidence of a primary tumour. Early vascular seeding prepares distal sites for colonisation while regional lymphatics are co-opted to promote facilitative cancer cell mutations. In response, the host mounts a global inflammatory and immunomodulatory response towards these cells supporting the concept that cancer is a systemic disease. Cancer staging systems should be refined to better reflect cancer cell loads in various tissue compartments while clinical perspectives should be broadened to encompass this view when approaching high-risk cancers. Measured adjunctive therapies implemented earlier for low-volume, in-transit cancer offers the prospect of preventing advanced disease and the need for heroic therapeutic interventions. This review seeks to re-appraise how we view the metastatic process for solid cancers. It will explore in-transit metastasis in the context of high-risk skin cancer and how it dictates disease progression. It will also discuss how these implications will influence our current staging systems and its consequences on management.
A fluorosis-free ingestible fluoride ion-containing composition comprising a mixture of pharmaceutically acceptable fluoride and monofluorophosphate in a weight ratio to provide not more than about fifty percent, and preferably not more than about twenty-five percent, of available fluoride ion from the fluoride and the balance from the monofluorophosphate. By "fluorosis-free" composition is meant one which, when ingested, minimizes of obviates the occurrence of fluorosis which is a common effect when fluoride is ingested. The composition may contain additional pharmaceutically acceptable adjuvants, such as vitamins, coloring, flavoring, carriers, stabilizers, preservatives, medicants and the like, and may be in the form of a powder, tablet, capsule, pill or a liquid in a suitable ingestible carrier. Preferred compounds are alkali metal, ammonium and amine fluorides and monofluorophosphates. Most preferred compounds are sodium fluoride (NaF) and sodium monofluorophosphate (MFP), whose formula is Na2FPO3 and the corresponding potassium salts. The compositions are especially adapted for use as a dietary supplement to provide substantially instantaneous low-dosage fluoride ion from the fluoride compound upon ingestion and a slow, prolonged release of fluoride ion from the monofluorophosphate.
The training program was applied by the researcher who also work as an academic nurse. The contact information of the patients was obtained and the contact information of the researcher was also given to the patients. In order to consolidate the information given, the training guide was given to the patients in the intervention group. After the training, the patients in the intervention group were contacted again in the 2nd week by using face-to-face interview and in the 4th-8th and 12th weeks by phone calls. During these interviews, the questions of the patients, if any, were answered and the problems they faced regarding the disease management were tried to be solved. In the last interview, an appointment day was determined to meet face-to-face at home, workplaces or hospital according to the preferences of the patients.
Darifenacin was not teratogenic in rats and rabbits at doses up to 50 and 30 mg/kg/day, respectively. At the dose of 50 mg/kg in rats, there was a delay in the ossification of the sacral and caudal vertebrae which was not observed at 10 mg/kg (approximately 13 times the AUC of free plasma concentration at MRHD). Exposure in this study at 50 mg/kg corresponds to approximately 59 times the AUC of free plasma concentration at MRHD. Dystocia was observed in dams at 10 mg/kg/day (17 times the AUC of free plasma concentration at MRHD). Slight developmental delays were observed in pups at this dose. At 3 mg/kg/day (five times the AUC of free plasma concentration at MRHD) there were no effects on dams or pups. At the dose of 30 mg/kg in rabbits, darifenacin was shown to increase postimplantation loss but not at 10 mg/kg (nine times the AUC of free plasma concentration at MRHD). Exposure to unbound drug at 30 mg/kg in this study corresponds to approximately 28 times the AUC at MRHD. In rabbits, dilated ureter and/or kidney pelvis was observed in offspring at 30 mg/kg/day and one case was observed at 10 mg/kg/day along with urinary bladder dilation consistent with pharmacological action of darifenacin. No effect was observed at 3 mg/kg/day (2.8 times the AUC of free plasma concentration at MRHD). There are no studies of darifenacin in pregnant women. Because animal reproduction studies are not always predictive of human response, ENABLEX should be used during pregnancy only if the benefit to the mother outweighs the potential risk to the fetus.
A process modifies the adsorption properties of the inner surface of a substance with macro and/or meso and/or micro and/or sub-micro-pores (MMMS-porous). The adsorbent surfaces are brought into contact with a fluid which is under super-critical conditions and contains one or more dissolved or dispersed modification agents. The modification agent is dissolved or dispersed in the fluid prior to or during contact with the fluid.  Examples are the use of zirconium(IV) oxide, palmitic acid, or oleic acid to modify active carbon or coke in a process to manufacture a molecular sieve and in which the fine-pored adsorbent is activated following heat treatment. In a process to modify active carbon with oleic acid, 0.5 g of grains of non-dried and untreated gas filter form-active carbon are weighed and introduced into a solution of 0.25 g oleic acid in 4.5 ml super-critical carbon dioxide at a temperature of 50C and pressure of 200 bar for 30 min. The pressure is then relaxed at the rate of 2 bar/min, desorbing carbon dioxide from the carbon, leaving the oleic acid in the active carbon.
Dysregulation and hyperactivation of innate immune responses can lead to the onset of systemic autoinflammatory diseases. Monogenic autoinflammatory diseases are caused by inborn genetic errors and based on molecular mechanisms at play, can be divided into inflammasomopathies, interferonopathies, relopathies, protein misfolding, and endogenous antagonist deficiencies. On the other hand, more common autoinflammatory diseases are multifactorial, with both genetic and non-genetic factors playing an important role. During the last decade, long-term memory characteristics of innate immune responses have been described (also called trained immunity) that in physiological conditions provide enhanced host protection from pathogenic re-infection. However, if dysregulated, induction of trained immunity can become maladaptive, perpetuating chronic inflammatory activation. Here, we describe the mechanisms of genetic and epigenetic dysregulation of the innate immune system and maladaptive trained immunity that leads to the onset and perpetuation of the most common and recently described systemic autoinflammatory diseases.
BACKGROUND: Pancreaticoduodenectomy is a highly morbid operation with significant resource utilization. Using a national cohort, we examined the interhospital variation in pancreaticoduodenectomy hospitalization cost in the United States.
METHODS: Adults undergoing elective pancreaticoduodenectomy in the setting of pancreatic cancer were tabulated from the 2016-2020 Nationwide Readmissions Database. A 2-level mixed-effects model was developed to evaluate the interhospital variation in pancreaticoduodenectomy hospitalization costs. Institutions within the top decile of risk-adjusted expenditures were defined as high-cost hospitals. Multivariable regression models were fitted to examine the association between high-cost hospital status and outcomes of interest. To account for the effects of complications on expenditures, a subgroup analysis comprising of patients with no adverse events was conducted.
RESULTS: The study included an estimated 24,779 patients with a median hospitalization cost of $38,800. After mixed-effects modeling, 40.9% of the cost variation was attributable to hospital, rather than patient, factors. Multivariable regression models revealed an association between high-cost hospital status and greater odds of complications and longer length of stay. Among patients without an adverse event, interhospital cost variation remained significant at 61.0%, and treatment at high-cost hospitals was similarly linked to longer length of stay.
CONCLUSION: Our study identified significant interhospital variation in pancreaticoduodenectomy hospitalization costs in the United States. Although high-cost hospital status was associated with increased odds of complications, variation remained significant even among patients without an adverse event. These results suggest the important role of hospital practices as contributors to expenditures. Further efforts to identify drivers of costs and standardize pancreatic surgical care are warranted.
Chronic cough is characterized by a state of cough hypersensitivity. We analyze the process of transpiration, by which water appears to evaporate from laryngeal and tracheal mucus as from the surface of a leaf, as a potential cause of cough hypersensitivity. In this process, osmotic pressure differences form across mucus, pulling water toward the air, and preventing mucus dehydration. Recent research suggests that these osmotic differences grow on encounter with dry and dirty air, amplifying pressure on upper airway epithelia and initiating a cascade of biophysical events that potentially elevate levels of ATP, promote inflammation and acidity, threaten water condensation, and diminish mucus water permeability. Among consequences of this inflammatory cascade is tendency to cough. Studies of isotonic, hypotonic, and hypertonic aerosols targeted to the upper airways give insights to the nature of mucus transpiration and its relationship to a water layer that forms by condensation in the upper airways on exhalation. They also suggest that, while hypertonic NaCl and mannitol may provoke cough and bronchoconstriction, hypertonic salts with permeating anions and non-permeating cations may relieve these same upper respiratory dysfunctions. Understanding of mucus transpiration and its role in cough hypersensitivity can lead to new treatment modalities for chronic cough and other airway dysfunctions promoted by the breathing of dry and dirty air.
Here we show that epigenetic control of Neuregulin-1 (NRG1) affects adipose differentiation of stem cells in vitro. Building on this finding, we established a model in which NRG1 is a white adipose tissue (WAT) specific regulator analogous to the role of NRG4 in black adipose tissue (BAT). In this light, NRG1 functions in a paracrine or autocrine manner to regulate formation of new adipocytes from stem populations, both in vitro and in vivo. In neurons, NRG1 has been shown already to play a similar role, promoting neuronal cell differentiation from progenitors in the vertebrate cortex and retina and even promoting neuronal differentiation in vitro. Similarly, in the heart, NRG1 promotes differentiation of cardiomyocytes from their stem cell progenitors both in vivo and in vitro and for this reason has been successfully tested in clinical trials for heart failure. Our model extends these findings to adipose biology and indicates that epigenetic control of NRG1 may constitute an intrinsic mechanism limiting the expansion of WAT depots, potentially elucidating important health implications for the comorbidities of obesity and providing treatment for obesity-related diseases.
Asthma is a chronic respiratory disease characterized by airway inflammation and airway hyperresponsiveness, which causes airflow obstruction. It is extremely prevalent, affecting an estimated 22 million Americans, and costly with loss of productivity and direct healthcare costs in the billions of dollars. The incidence and prevalence of asthma are increasing, both in the US and around the world. This increase comes despite greater understanding of the inflammatory and allergic basis for asthma, and despite better antiinflammatory medications. One explanation for the increasing prevalence of asthma is the concomitant increase in obesity, with the majority of Americans now overweight or obese. Numerous studies have convincingly linked asthma and obesity, and demonstrated increased obstruction with weight gain and decreased obstruction with weight loss. However, the mechanisms that underlie this linkage are not known.

We believe that low lung volumes contribute to the pathogenesis and severity of asthma. End-expiratory lung volume is decreased in obesity, and likely falls further during sleep, particularly in overweight and obese patients. Both upper and lower airway resistance increase with decreasing lung volumes, as airways become smaller. However, prior work has shown that lower airway resistance increases out of proportion to the decrease in lung volume that occurs during sleep in asthma patients. This difference between controls and people with asthma has not been further explored, yet may provide insight into asthma pathogenesis and provide potential targets for therapy.

Therefore, we propose a series of experiments to define the impact of lung volumes during sleep on airway resistance. One of these experiments will be to to test the hypothesis that lung stretch can be used therapeutically by tonically and dynamically increasing lung volumes during sleep using bi-level positive airway pressure. This research can help delineate asthma pathogenesis and may help improve therapeutic options in this exceedingly common disease.
Treatment group: start jejunostomy feeds from day 1, with target of 1000ml = 1000kCal (= 40cc/hour). To equilibrate energy intake during build up fase, Glucose 20% is given at a total cumulative dose taking into account the dose of j-drip, cumulative not exceeding 40cc/hr. Oral feeds are started at the same time as in the control group (reg. day 5) Jejunostomy feeds are then continued for 6 weeks together with oral intake with a continuous energy administration of 1000kCal, and then stopped. After this time, patients should be on regular full diet in both groups. If failure and step-back needed, temporary switch to Glc 20% is done to maintain fluid and calory administration.

Hypoxia plays an important role in several pathologies, e.g. chronic obstructive pulmonary disease and obstructive sleep apnea syndrome, and is linked to an increased thrombosis risk. Furthermore, oxygen deprivation is associated with hypercoagulability. In this study, we investigated the effect of gender and exercise on the coagulation potential under hypoxic conditions at high altitude by assessing thrombin generation (TG) and platelet activation. Hereto, ten healthy volunteers were included (50 % male, median age of 27.5 years). The measurements were conducted first at sea level and then twice at high altitude (3883 m), first after a passive ascent by cable car and second after an active ascent by a mountain hike. As expected, both the passive and active ascent resulted in a decreased oxygen saturation and an increased heart rate at high altitude. Acute mountain sickness symptoms were observed independently of the ascent method. After the active ascent, platelet, white blood cell and granulocyte count were increased, and lymphocytes were decreased, without a gender-related difference. FVIII and von Willebrand factor were significantly increased after the active ascent for both men and women. Platelet activation was reduced and delayed under hypobaric conditions, especially in women. TG analysis showed a prothrombotic trend at high altitude, especially after the active ascent. Women had a hypercoagulable phenotype, compared to men at all 3 timepoints, indicated by a higher peak height and endogenous thrombin potential (ETP), and shorter lag time and time-to-peak. In addition, ETP and peak inhibition by thrombomodulin was lower in women after the active ascent, compared to men. Interestingly, data normalisation for subject baseline values indicated an opposing effect of altitude-induced hypoxia on α2-macroglobulin levels and TG lag time between men and women, decreasing in men and increasing in women. We conclude that hypoxia increases TG, as well as FVIII and VWF levels in combination with exercise. In contrast, platelets lose their responsiveness at high altitude, which is most pronounced after heavy exercise. Women had a more pronounced prothrombotic phenotype compared to men, which we theorize is counterbalanced under hypobaric conditions by decreased platelet activation.
Ischemic stroke is a major cause of death and disability in adults. Hypothermic treatment is successful in treating neonatal cerebral ischemia, but its application is restricted in adult patients due to complex management strategies and severe adverse effects. Two homologous RNA-binding proteins, RBM3 and CIRP, are the only known cold-inducible proteins in vertebrates, and their expression levels are robustly elevated by mild to moderate hypothermia. In previous studies, we and others have demonstrated that both RBM3 and CIRP mediate the neuroprotective and neurogenic effects of hypothermia in cell and animal models. However, CIRP can also be detrimental to neurons by triggering neuroinflammatory responses, complicating its post-stroke functions. In this study, we compared the properties of the two cold-inducible RNA-binding proteins after ischemic stroke. Our results indicated that RBM3 expression was stimulated in the ischemic brain of stroke patients, while CIRP expression was not. In an experimental model, RBM3 can ameliorate ischemic-like insult by promoting neuronal survival and eliciting anti-inflammatory responses in activated microglia, while the impact of CIRP was intriguing. Collectively, our data supported the notion that RBM3 may be a more promising therapeutic target than CIRP for treating ischemic stroke. We further demonstrated that zr17-2, a small molecule initially identified to target CIRP, can specifically target RBM3 but not CIRP in microglia. zr17-2 demonstrated anti-inflammatory and neuroprotective effects after ischemic stroke both in vitro and in vivo, suggesting its potential therapeutic value.
Low pH in the gut is associated with severe inflammation, fibrosis, and colorectal cancer (CRC) and is a hallmark of active inflammatory bowel disease (IBD). Subsequently, pH-sensing mechanisms are of interest for the understanding of IBD pathophysiology. Tissue hypoxia and acidosis-two contributing factors to disease pathophysiology-are linked to IBD, and understanding their interplay is highly relevant for the development of new therapeutic options. One member of the proton-sensing G protein-coupled receptor (GPCR) family, GPR65 (T-cell death-associated gene 8, TDAG8), was identified as a susceptibility gene for IBD in a large genome-wide association study. In response to acidic extracellular pH, GPR65 induces an anti-inflammatory response, whereas the two other proton-sensing receptors, GPR4 and GPR68 (ovarian cancer G protein-coupled receptor 1, OGR1), mediate pro-inflammatory responses. Here, we review the current knowledge on the role of these proton-sensing receptors in IBD and IBD-associated fibrosis and cancer, as well as colitis-associated cancer (CAC). We also describe emerging small molecule modulators of these receptors as therapeutic opportunities for the treatment of IBD.
