AimsElevated levels of endogenous opioids play a pivotal role in several deleterious consequences of cholestasis. Renal dysfunction occurs in cholestasis but its exact mechanism is still unknown. In this study, we investigated the role of endogenous opioids in cholestasis induced nephrotoxicity.Main methodsThirty-five rats were divided into five groups. In groups 1 and 2 BDL rats received either daily subcutaneous 20 mg/kg of naltrexone or its vehicle, for 7 days after BDL. In groups 3 and 4, BDL or Sham rats received no injections. In group 5, normal rats received subcutaneous injections of 20 mg/kg/day of naltrexone for 7 days. At the 7th day, 24 h urine was collected to measure urinary N-acetyl-β-D-glucosaminidase (NAG) as an early marker of renal tubular injury. Kidney samples were then collected for light and electron microscopic studies.Key findingsBDL significantly increased NAG activity compared to sham groups. Naltrexone significantly reversed NAG activity to normal levels in BDL animals. Naltrexone treatment in BDL animals also significantly reversed ALT and AST to their normal levels. In light and electron microscopic studies, there were significant structural alterations in BDL samples, which were mostly prevented in naltrexone treated BDL animals.SignificanceSignificant changes in urinary NAG activity and renal morphology of cholestatic rats were reversed by naltrexone treatment. These results suggest a possible role for endogenous opioids in inducing cholestatic nephrotoxicity. 相似文献

Enzymic hydrolysis of “polygalacturonic acid” gave a mixture of oligomers which was fractionated by ion-exchange chromatography. The resulting di- and tri-saccharides were treated, respectively, with methanol and ethylene oxide, and the resulting esters were reduced with sodium borohydride. Treatment of the products with acetic anhydride and sulfuric acid, followed by deacetylation, produced the title compound. 相似文献

Inner and outer membranes of Escherichia coli and contact zones were isolated and fused separately with giant liposomes amenable to patch-clamp recording. Different types of large pressure-activated channels were localized in the inner membrane fraction which also contained smaller, pressure-insensitive channels. The outer membrane contained pressure-insensitive channels with large conductances and long opening and closing times which are likely to be porins. Large channels were also observed in contact zones. 相似文献

Bioconjugate formats provide alternative strategies for antigen targeting with bispecific antibodies. Here, PSMA-targeted Fab conjugates were generated using different bispecific formats. Interchain disulfide bridging of an αCD3 Fab enabled installation of either the PSMA-targeting small molecule DUPA (SynFab) or the attachment of an αPSMA Fab (BisFab) by covalent linkage. Optimization of the reducing conditions was critical for selective interchain disulfide reduction and good bioconjugate yield. Activity of αPSMA/CD3 Fab conjugates was tested by in vitro cytotoxicity assays using prostate cancer cell lines. Both bispecific formats demonstrated excellent potency and antigen selectivity. 相似文献

Circulating microRNAs (miRNAs) have been shown as promising biomarkers for various diseases. We investigated the predictive potential of circulating endothelium-enriched miR-126 in type 2 diabetes patients (T2D) without chronic complications and T2D patients with coronary artery diseases (CAD). The expression levels of circulating miR-126, determined by quantitative real time PCR, were decrease in peripheral blood of T2D patients and T2D with CAD compared with healthy controls. MiR-126 strongly associated with T2D and CAD, negatively correlated with LDL in CAD patients and differentiated between T2D patients, T2D patients with CAD and healthy subjects. Circulating miR-126 may serve as a biomarker for predicting patients with T2D and diabetic CAD. 相似文献

Glucose and lipid metabolic parameters play crucial roles in metabolic syndrome and its major feature of insulin resistance. This study was designed to investigate whether dietary astaxanthin oil (ASX-O) has potential effects on metabolic syndrome features in an SHR/NDmcr-cp (cp/cp) rat model. Oral administration of ASX (50 mg/kg/day) for 22 weeks induced a significant reduction in arterial blood pressure in SHRcp. It also significantly reduced the fasting blood glucose level, homeostasis index of insulin resistance (HOMA-IR), and improved insulin sensitivity. The results also showed an improved adiponectin level, a significant increase in high-density lipoprotein cholesterol, a significant decrease in plasma levels of triglycerides, and non-esterified fatty acids. Additionally, ASX showed significant effects on the white adipose tissue by decreasing the size of the fat cells. These results suggest that ASX ameliorates insulin resistance by mechanisms involving the increase of glucose uptake, and by modulating the level of circulating lipid metabolites and adiponectin. 相似文献

In keeping with a long-standing tradition, Yale Medical and Physician Associate students gather at a ceremony each year after the completion of the anatomy course. The ceremony is a chance to reflect and to give thanks. It gives students the opportunity to articulate their gratitude to the selfless individuals who donated their bodies for the benefit of education. Many family members of the donors attend the ceremony. By reading poetry, performing musical pieces, and presenting works of art, the students and their teachers express some of the emotions and thoughts that the anatomy course has evoked. The following are some of the contributions presented at this year's ceremony. 相似文献
