Ming Xie, Wenhai Luo, Stephen R Gray
We described a synchrotron-based infrared (IR) microscopic method to characterize fouling layer induced by organic foulants and colloidal silica in membrane distillation (MD). This technique, utilizing the ultrahigh brightness of synchrotron infrared source, enables spectra with high signal-to-noise ratio that was obtained from micrometer-sized samples. Our results showed that synchrotron IR mapping was able to resolve the foulant spatial distribution in combined fouling in MD. Synchrotron IR mapping showed the spatial distribution of binary foulant (i...

Margaret E Thompson, Mary Barth Noel
The assessment of nutritional status in adults should begin with a complete history, including intake of fruits and vegetables, sources of fat, and added sugar (eg, sugar-sweetened beverages). The history should include social factors that may impede a patient's ability to obtain food, as well as any factors that might interfere with preparing, chewing, and digesting food and absorbing nutrients. The physical examination should include measurement of height and weight and calculation of body mass index. It also may include measurements of waist circumference and waist to hip ratio, and an evaluation of strength...

BACKGROUND: Surgical site infections (SSI) remain a major source of morbidity and cost after resection of intra-abdominal malignancies. Negative pressure wound therapy (NPWT) has been reported to significantly reduce SSI when applied to the closed laparotomy incision. This paper reports results of a randomized clinical trial examining the effect of NPWT on SSI rates in surgical oncology patients with increased risk for infectious complications. STUDY DESIGN: From 2012-2016, 265 patients underwent open resection of intra-abdominal neoplasms stratified into three groups: gastrointestinal (n=57), pancreas (n=73), and peritoneal surface malignancy (n=135)...

Human infections with highly pathogenic avian influenza A (H5N1) virus are frequently fatal but the mechanisms of disease remain ill-defined. H5N1 infection is associated with intense production of proinflammatory cytokines, but whether this cytokine storm is the main cause of fatality or is a consequence of extensive virus replication that itself drives disease remains controversial. Conventional intratracheal inoculation of a liquid suspension of H5N1 influenza virus in nonhuman primates likely results in efficient clearance of virus within the upper respiratory tract and rarely produces severe disease...

Mammalian tissues rely on a variety of nutrients to support their physiological functions. It is known that altered metabolism is involved in the pathogenesis of cancer, but which nutrients support the inappropriate growth of intact malignant tumors is incompletely understood. Amino acids are essential nutrients for many cancer cells that can be obtained through the scavenging and catabolism of extracellular protein via macropinocytosis. In particular, macropinocytosis can be a nutrient source for pancreatic cancer cells, but it is not fully understood how the tumor environment influences metabolic phenotypes and whether macropinocytosis supports the maintenance of amino acid levels within pancreatic tumors...

BACKGROUND: The prognostic significance of serum albumin levels in patients with sepsis has previously been reported; however, these studies have not excluded the potential confounding effect of exogenous albumin administration. In this study, we investigate the predictive value of serum albumin for the prognosis of severe sepsis without the interference of exogenous albumin administration. METHODS: A prospective cohort study was conducted from April to November 2014 in the internal and surgical intensive care units of a tertiary care hospital...

Ionic organic chemicals are a class of chemicals that is released in the environment in a large amount from anthropogenic sources. Among various chemical and biological processes, binding to serum albumin is particularly relevant for the toxicokinetic behavior of ionic chemicals. Several experimental studies showed that steric effects have a crucial influence on the sorption to bovine serum albumin (BSA). In this study, we investigated whether a 3D quantitative structure-activity relationship (3D-QSAR) model can accurately account for these steric effects by predicting the BSA-water partition coefficients (KBSA/water) of neutral and anionic organic chemicals...

Chemical warfare agents represent a continuous and considerable threat to military personnel and the civilian population. Such compounds are prohibited by the Chemical Weapons Convention, to which adherence by the member states is strictly controlled. Therefore, reliable analytical methods for verification of an alleged use of banned substances are required. Accordingly, current research focuses on long-term biomarkers derived from covalent adducts with biomolecules such as proteins. Recently, we have introduced a microbore liquid chromatography/electrospray ionization high-resolution tandem mass spectrometry method allowing for the investigation of two different classes of adducts of the nerve agent VX with human serum albumin (HSA)...

Nutrient transporters have been explored for biomimetic delivery targeting the brain. The albumin-binding proteins (e.g., SPARC and gp60) are overexpressed in many tumors for transport of albumin as an amino acid and an energy source for fast-growing cancer cells. However, their application in brain delivery has rarely been investigated. In this work, SPARC and gp60 overexpression was found on glioma and tumor vessel endothelium; therefore, such pathways were explored for use in brain-targeting biomimetic delivery...

This retrospective study examined the effect of time to intervention on outcome in cases of dogs with secondary septic peritonitis, and also searched for other potential prognostic factors. The medical records of 55 dogs were reviewed. No association was found between outcome and the time from hospital admission to surgical source control. However, several other factors were found to influence survival, including: age, needing vasopressors, lactate, pre-operative packed cell volume, serum alkaline phosphatase, serum total bilirubin, and post-operative serum albumin...

The underutilized Kenyan variety of Dolichos lablab bean seeds serve as a good source of natural antioxidants, which can probably be effective in reducing the risk of occurrence of several diseases. This study was undertaken for the first time to address the limited knowledge regarding the antioxidant activities of lablab beans. Moreover, their DNA damage inhibitory activity, bovine serum albumin (BSA) damage inhibitory activity, and the inhibition of acetylcholinesterase and porcine α-amylase were also investigated...

Long-chain fatty acids cross a few membranes on their way from the capillary blood to the cardiomyocyte cytosol, where they are utilized as an essential source of energy. Details of the transport mechanism across those membranes remained elusive despite decades of laboratory and theoretical work. Here we inspect several optional scenarios for the crossing of the luminal membrane of the endothelial cell, the first barrier that should be crossed: a passive diffusion, facilitation by receptors for albumin and facilitation by fatty acids transporters...

The renal proximal tubules are a key functional component of the kidney and express the angiotensin precursor angiotensinogen; however, it is unclear the extent that tubular angiotensinogen reflects local synthesis or internalization. Therefore, the current study established the extent that angiotensinogen is internalized by proximal tubules and the intracellular distribution. Proximal tubules were isolated from the kidney cortex of male sheep by enzymatic digestion and a discontinuous Percoll gradient. Tubules were incubated with radiolabeled 125I-angiotensinogen for 2 hrs at 37°C in serum/phenol-free DMEM/F12 media...

BACKGROUND: Human follicular fluid (FF) is a unique biological fluid in which the oocyte develops in vivo, and presents an optimal source for non-invasive biochemical predictors. Oocyte quality directly influences the embryo development and hence, may be used as a predictor of embryo quality. Peptide profiling of FF and its potential use as a biomarker for oocyte quality has never been reported. METHODS: This study screened FF for peptide biomarkers that predict the outcome of in vitro fertilization (IVF)...

Renal proximal tubule epithelial cells (PTECs) are known to reabsorb salts and small plasma proteins filtered through Bowman's capsule. Following acute kidney injury, PTECs assume some characteristics of hepatocytes in producing various plasma proteins. We now demonstrate that even at a resting state, a PTEC cell line, HK2 expresses mRNAs for and synthesizes and secretes plasma proteins in a complex with complement C3, an α2 -macroglobulin family chaperone, including albumin, transferrin, α1 -antitrypsin, α1 -antichymotrypsin, α2 -HS-glycoprotein, ceruloplasmin, haptoglobin, C1-inhibitor, secreted phosphoprotein-24, and insulin-like growth factor-1...
