OBJECTIVE: Numerous studies have indicated nephrotoxic effects of sevoflurane because of its two bioproducts compound A and fluoride. Cystatin C (CyC) is a more sensitive biomarker than creatinine to show early and mild changes in kidney function. We designed this prospective randomised study to compare the effects of low-flow sevoflurane anaesthesia and low-flow desflurane anaesthesia on renal functions based on CyC levels. No studies have evaluated the effects of low-flow sevoflurane anaesthesia on renal functions based on CyC levels to date...

Because hepatic dysfunction is common in patients with heart failure (HF), the Model for End-Stage Liver Disease (MELD) may be attractive for risk stratification. Although alternative scores such as the MELD-XI or MELD-Na may be more appropriate in HF populations, the short-term clinical implications of these in patients with acute heart failure (AHF) are unknown. The MELD-XI and MELD-Na were calculated at baseline in 453 patients with AHF in the DOSE-AHF and ROSE-AHF trials. The correlations and associations for each score with cardiorenal biomarkers, short-term end points at 72 hours including worsening renal function and clinical events to 60 days were determined...

BACKGROUND: Acute kidney injury (AKI) following cardiopulmonary bypass affects 5% of patients, representing significant postoperative morbidity and mortality. Animal models have shown an increased uptake of lipid microemboli (LME) into the renal vasculature, potentially indicating ischaemic causation. This study tested a new lipid filtration system (RemoweLL) against a conventional system with no lipid-depleting capacity to determine the efficacy of the filtration system and its effects on renal function...

Competing endogenous RNA (ceRNA) is a newly proposed mechanism that describes a crosstalk among lncRNAs, mRNAs and their shared miRNAs. In this study, the role of miR-338-3p (miR-338) in the progression of esophageal cancer and its involve in the ceRNA regulatory circuit lncRNA-Snhg1/CST3 were explored. MiR-338 displayed a 30% decreased expression in esophageal squamous cell carcinoma tissues compared with the adjacent. Then, proto-oncogene CST3 was predicted and validated as a target gene of miR-338. Gain-and-loss-function experiments indicated that miR-338 suppressed expression of CST3 protein (also Cystatin C, CysC), promoted expression of apoptotic proteins caspase-8/3, attenuated esophageal carcinoma cell growth and induced its apoptosis...

Bioadhesion and bio-adsorption of proteins, glycoproteins and other biomolecules are ubiquitous phenomena in the oral cavity. While the protective role of the adsorbed salivary biomolecules on teeth (the acquired enamel pellicle) is well established, it has yet to be defined whether comparable processes occur on the desquamating oral soft tissues. The general term for these layers is pellicle, but due to the different characteristics of the coated surfaces the enamel pellicle and mucosal pellicle are their own entities...

Understanding the genetic basis of phenotypic plasticity is crucial for predicting and managing climate change effects on wild plants and crops. Here, we combined crop modeling and quantitative genetics to study the genetic control of oil yield plasticity for multiple abiotic stresses in sunflower. First we developed stress indicators to characterize 14 environments for three abiotic stresses (cold, drought and nitrogen) using the SUNFLO crop model and phenotypic variations of three commercial varieties. The computed plant stress indicators better explain yield variation than descriptors at the climatic or crop levels...

BACKGROUND: Cystatin-C (CyC) is a middle molecule that is freely filtered at the glomerulus and almost completely reabsorbed by the proximal tubules. The aim of this study was to evaluate serum CyC and its reduction ratio as a biomarker for assessing the adequacy of the hemodialysis (HD) sessions in children with end-stage renal disease on maintenance HD. We also compared levels of CyC in patients on low-flux HD (LFH) and high-flux HD (HFH). METHODS: Forty patients were included in the study and divided into two groups, with one group (16 patients) receiving HFH and the other group receiving LFH (24 patients) (high-flux and low-flux polysulfone filters, respectively)...

BACKGROUND: The risk of incorrect medication dosing is high in frail older people. Therefore, accurate assessment of the glomerular filtration rate is important. OBJECTIVE: The objective of this study was to compare the estimated glomerular filtration rate using creatinine- and cystatin C-based formulae, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations, in frail older people. We hypothesized that frailty determines the difference between the creatinine- and cystatin C-based formulae...

Discovery of new protease inhibitors may result in potential therapeutic agents or useful biotechnological tools. Obtainment of these molecules from natural sources requires simple, economic and highly efficient purification protocols. The aim of this work was the obtainment of affinity matrices by the covalent immobilization of dipeptidyl peptidase IV (DPP-IV) and papain onto cellulose membranes, previously activated with formyl (FCM) or glyoxyl groups (GCM). GCM showed the highest activation grade (10.2 µmol aldehyde/cm(2))...

BACKGROUND: The monocled cobra (Naja kaouthia) is a medically important venomous snake in Southeast Asia. Its venom has been shown to vary geographically in relation to venom composition and neurotoxic activity, indicating vast diversity of the toxin genes within the species. To investigate the polygenic trait of the venom and its locale-specific variation, we profiled and compared the venom gland transcriptomes of N. kaouthia from Malaysia (NK-M) and Thailand (NK-T) applying next-generation sequencing (NGS) technology...

Two cysteine proteinase inhibitors from cowpea, VuCys1 and VuCys2, were produced in E. coli ArcticExpress (DE3). The recombinant products strongly inhibited papain and chymopapain as well as the midgut proteases from Callosobruchus maculatus larvae, a bruchid that uses cysteine proteases as major digestive enzymes. Heat treatment at 100°C for up to 60min or incubation at various pH values caused little reduction in the papain inhibitory activity of both inhibitors. Moreover, minor conformational variations, as probed by circular dichroism spectroscopy, were observed after VuCys1 and VuCys2 were subjected to these treatments...
