Feline leukemia virus (FeLV) is an oncogenic retrovirus of cats. Immunoassays for the p27 core protein of FeLV aid in the detection of FeLV infections. Commercial microtiter-plate ELISAs have rapid protocols and visual result interpretation, limiting their usefulness in high-throughput situations. The purpose of our study was to validate the PetChek FeLV 15 ELISA, which is designed for the reference laboratory, and incorporates sequential, orthogonal screening and confirmatory protocols. A cutoff for the screening assay was established with 100% accuracy using 309 feline samples (244 negative, 65 positive) defined by the combined results of FeLV PCR and an independent reference p27 antigen ELISA...

Inflammatory bowel disease (IBD) is a devastating disease that is associated with excessive inflammation in the intestinal tract in genetically susceptible individuals and potentially triggered by microbial dysbiosis. This illness markedly predisposes patients to thrombophilia and chronic debility as well as bowel, lymphatic, and liver cancers. Development of new therapies is needed to re-establish long-term immune tolerance in IBD patients without increasing the risk of opportunistic infections and cancer...

The alterations and low levels of circulating branched chain amino acids (BCAAs), leucine, isoleucine and valine, are associated with liver diseases. The study was designed to evaluate hepatoprotective effect of BCAAs on CCl4 -induced liver fibrosis and to investigate the molecular mechanisms underlying these effects in rats. Thirty male rats were divided into three groups. Control group (n=10), CCl4 group (n=10); rats were injected with CCl4 (1 mL/kg of 0.5:1 v/v injected i.p. twice weekly for 12 weeks). CCl4 +BCAAs group (n=10); rats were injected with similar doses of CCl4 and supplemented with a mixture of 600 mg/kg BCAAs (2: 1: 1...

Metabolic syndrome (MetS) has become one of the main concerns for public health because of its link to cardiovascular disease. Murine models have been used to study the effect of MetS on the cardiovascular system, but they have limitations for studying cardiac electrophysiology. In contrast, the rabbit cardiac electrophysiology is similar to human, but a detailed characterization of the different components of MetS in this animal is still needed. Our objective was to develop and characterize a diet-induced experimental model of MetS that allows the study of cardiovascular remodeling and arrhythmogenesis...

To establish an animal model of acute-on-chronic liver failure (ACLF) that would replicate the pathological process of ACLF in humans, rats were administered porcine serum (PS) for 11 weeks. Liver fibrosis was determined by pathological and biochemical assessments. The animals then were injected with d-galactosamine (d-gal) and lipopolysaccharide (LPS). The survival times of animals with cirrhosis and ACLF were determined over 48 h. Other animals were killed at 0, 4, 8 and 12 h after administration of d-gal/LPS...

For many years, there has been a search for a set of biochemical parameters that could facilitate the assessment of severity, prognosis, and administration of early and appropriate treatment in acute pancreatitis. Administration of treatment within the first 48 hours since admission is associated with many problems of distinguishing patients with a mild form of acute pancreatitis (AP) from those with a severe form of acute pancreatitis. STUDY AIM: To assess the relationship between the extent of change in the concentration of 10 selected biochemical indicators: amylase, lipase, total bilirubin, creatinine, uric acid, aspartate transaminase, alanine transaminase, glucose, magnesium, and iron and histopathological lesions in the pancreas within 2 and 6 hours since induction of AP...

Cilostazol undergoes extensive liver metabolism. However, the transporter-mediated hepatic disposition of cilostazol remains unknown. The present study was performed to investigate the hepatic uptake and biliary excretion of cilostazol and its metabolites (OPC-13015 and OPC-13213) using rat liver and human transporter-transfected cells in vitro. Cilostazol uptake by rat liver slices and isolated rat hepatocytes exhibited time-, concentration-, and temperature-dependency and was decreased by Oatp inhibitors, which suggested that Oatp was involved in the hepatic uptake of cilostazol...

Coupled plasma filtration and adsorption (CPFA) is a detoxification system that combines a plasma adsorption circuit and a continuous renal replacement therapy circuit. Its main application is for sepsis and septic shock with or without acute renal failure. Several recent studies have suggested that CPFA can reduce the mortality when the volume of plasma absorbed on the styrenic resin is at least >0.18 L/kg/day. At present, new applications for CPFA are under investigation, also in patients without significant kidney failure...

Rosemary ( Rosmarinus officinalis; RM) and thyme ( Thymus vulgaris; TV) are used as remedies. We designed this work to investigate the preventive effect of aqueous extracts of RM or TV on the gentamicin (GM)-induced hepatotoxicity and abnormalities of lipid profile in rats. Both plant extracts exhibited an in vitro antioxidant activity as determined by the 1,1-diphenyl-2-picrylhydrazyl assay. Radical scavenging activity for TV extract was 48.7% and for RM extract was 25.6%. Polyphenolic determination by high-performance liquid chromatography for both extracts revealed that catechin, coumarin, cinnamic acid and rutin were detected in both extracts...

Despite widespread use of bromuconazole as a pesticide for food crops and fruits, limited studies have been done to evaluate its toxic effects. Here, we evaluated the hepatotoxic effect of bromuconazole using classical toxicological (biochemical analysis and histopathological examination) and gene-based molecular methods. Male rats were treated either orally or topically with bromuconazole at doses equal to no observed adverse effect level (NOAEL) and 1/10 LD50 for 90 days. Bromuconazole increased activities of liver enzymes (ALT, AST, ALP, and ACP), and levels of bilirubin...

Perihilar cholangiocarcinoma (pCC, also known as a Klatskin tumor) is the most common type of cholangiocarcinoma (CC). Preoperative biliary drainage (PBD) is indicated for pCC patients with acute cholangitis or patients who need portal vein embolization (PVE). However, the routine performance of PBD in other patients with pCC is still controversial. The current study retrospectively examined patients with pCC who did not undergo PVE and who did not have cholangitis who were seen at this Hospital to assess the advantages and disadvantages of PBD...

Partial correlation and regression analyses were used in this study. We showed that there is a linear relationship between bone mineral density and serum uric acid within the normal physiologic range, and higher serum uric acid levels had a protective effect on bone loss in postmenopausal osteoporosis. PURPOSE: The significance of the relationship between lumbar bone mineral density (()BMD) and serum uric acid (SUA) levels is unclear. The aims of this study were to investigate on a population-level the association between lumbar BMD and SUA within the normal physiologic range and to determine whether SUA plays a protective role in bone loss in healthy postmenopausal Chinese women...

In liver transplant (LT) recipients, the cause of graft dysfunction in pregnancy is often difficult to ascertain. Moreover, a liver biopsy in late pregnancy is often avoided as a consequence of patient and physician factors. Management of graft dysfunction can be difficult in this setting. We report a 30-year-old female LT recipient who developed acutely deranged liver biochemistry during the third trimester of her first pregnancy. At 29 weeks gestation, her liver function test (LFT) became abnormal; AST peaked at 978 IU/L (normal range 10-50), GGT 25 IU/L (normal range 1-55), bilirubin 1...
