A whole-organ regeneration approach, using a decellularised xenogeneic liver as a scaffold for the construction of a transplantable liver was recently reported. Deriving suitable scaffolds was the first step towards clinical application; however, effective recellularisation remains to be achieved. This report presents a strategy for the improvement of the recellularisation process, using novel cell-seeding technique and cell source. We evaluated recellularised liver grafts repopulated through the portal vein or the biliary duct with mice adult hepatocytes or E14...

Cow's milk is an important source of proteins in human nutrition. On average, cow's milk contains 3.5% protein. The most abundant proteins in bovine milk are caseins and some of the whey proteins, namely beta-lactoglobulin, alpha-lactalbumin, and serum albumin. A number of allelic variants and post-translationally modified forms of these proteins have been identified. Their occurrence varies with breed, individuality, stage of lactation, and health and nutritional status of the animal. It is therefore essential to have reliable methods of detection and quantitation of these proteins...

BACKGROUND: Carbonylated proteins (CPs) are generated by the reaction of basic amino acid residues in proteins with aldehyde compounds produced during lipid peroxidation. CPs in the stratum corneum (SC) impact skin conditions such as skin moisture functions including water content and transepidermal water loss (TEWL). In addition, CPs can be frequently seen in the SC from sun-exposed sites compared with sun-protected sites. OBJECTIVE: The aim of this study was to reveal whether CPs could be a generation source of reactive oxygen species (ROS) in the SC following exposure to ultraviolet (UV) radiation and to identify the type of ROS and its generation mechanism...

The reaction products and intermediates of the three CO-releasing manganese(i) coordination compounds [Mn(tpm)(CO)3](+), [Mn(bpza)(CO)3] and [Mn(tpa)(CO)3](+) were analysed by combining IR-spectroscopy, electrochemical measurements and single-crystal XRD. The intermediate formation of manganese(i) biscarbonyl compounds and the rather facile oxidation of these species were identified as key reaction steps that accompany CO liberation. For the use of [Mn(I)(CO)3] complexes as light-triggered CO sources, the results indicate that in this case photo- and redox-chemistry seem to be strongly coupled which could be important and potentially even useful in the pharmacological context...

Extracts of leaves, seeds, roots, and stem from a tropical legume, C. ensiformis, were prepared employing buffers and detergent in aqueous solution. Leaf extracts had the highest protein content and the most pronounced peptidase activity with optimal pH in the neutral to alkaline range. All extracts exhibited peaks of activity at various pH values, suggesting the presence of distinctive classes of proteases. N-α-Tosyl-L-arginine methyl ester hydrolysis was maximal at 30°C to 60°C and peptidase activity from all extracts presented very good thermal stability after 24 h incubation at 70°C...

INTRODUCTION: Post-operative bile leak (BL) and post hepatectomy liver failure (PHLF) are the major potential sources of morbidity among patients undergoing liver resection. We sought to define the incidence of BL and PHLF among a large cohort of patients, as well as examine the prognostic impact of model for end-stage liver disease (MELD) and albumin-bilirubin (ALBI) scores to predict these short-term outcomes. MATERIALS AND METHODS: Patients who underwent a hepatectomy between January 1, 2014 and December 31, 2014 were identified using the National Surgical Quality Improvement Program (NSQIP) liver-targeted database...

PURPOSE: One of the most important events leading to morbidity and mortality in patients with severe sepsis is the development of global tissue hypoperfusion and oxidative damage. Ischemia-modified albumin (IMA), an albumin generated under ischemic and oxidative conditions, is a marker of oxidative stress and hypoperfusion. Here, we investigated whether IMA level could predict short-term mortality with severe sepsis. METHODS: A prospective cohort study was conducted from April 2014 to October 2014 in intensive care units in a tertiary hospital...

Plasminogen is a major plasma protein and the zymogen of the broad spectrum protease plasmin. Plasmin activity leads to tissue degradation, direct and through activation of metalloproteinases. Infected tooth root canals, as a consequence of the inflammatory response and eventual necrosis, contain tissue fluid and blood components. These will coat the root canal walls and act as conditioning films that allow bacterial biofilms to grow and be a potential source of hematogenously spreading bacteria. We investigated the effect of in vitro surface conditioning with human plasminogen on the initial adhesion of bacteria...

Cholestatic itch is a feature of numerous hepatobiliary disorders such as primary biliary cirrhosis, primary sclerosing cholangitis, the inherited form of cholestasis, and intrahepatic cholestasis of pregnancy. Although undervalued by physicians, cholestatic itch can be a source of great discomfort to the patient and significantly affects quality of life. Many pruritogens such as bile salts, opioids, serotonin, and histamine have been implicated in the pathogenesis of cholestatic itch, but no causative link has ever been established...

The aim of this study was to identify the source of haze formation in red wine after the addition of carboxymethyl cellulose (CMC) and to characterize the dynamics of precipitation. Ninety commercial wines representing eight grape varieties were collected, tested with two commercial CMC products, and analyzed for susceptibility to haze formation. Seventy-four of these wines showed a precipitation within 14 days independent of the CMC product used. The precipitates of four representative samples were further analyzed for elemental composition (CHNS analysis) and solubility under different conditions to determine the nature of the solids...

Hydrogen sulfide (H2S) is an important gaseous signaling molecule in the cardiovascular system. In addition to free H2S, H2S can be oxidized to polysulfide which can be biologically active. Since the impact of H2S on endothelial solute barrier function is not known, we sought to determine whether H2S and its various metabolites affect endothelial permeability. In vitro permeability was evaluated using albumin flux and transendothelial electrical resistance. Different H2S donors were used to examine the effects of exogenous H2S...

AIM: Since the discontinuation of a commercially available liquid calcium medicine, there have been various local strategies to obtain adequate calcium levels, particularly in suspected 22Q11.2 deletion syndrome children post cardiothoracic surgery. Pharmacy obtained on special order a Calcium Liquid food supplement (0.5 mmol calcium/ml) for use in those children whom effervescent tablets did not appear to improve corrected calcium. Anecdotally it was thought that calcium liquid was better tolerated and absorbed, resulting in quicker recovery time of corrected calcium than use of the effervescent tablets...

Optimal dietary protocols for the athletic canine are often defined by requirements for endurance athletes that do not always translate into optimal dietary interventions for all canine athletes. Prior research studying detection dogs suggests that dietary fat sources can influence olfaction; however, as fat is added to the diet the protein calories can be diminished potentially resulting in decreased red blood cell counts or albumin status. Optimal macronutrient profile for detection dogs may be different considering the unique work they engage in...
