BACKGROUND/AIMS: Pancreatic cancer (PC) is ranked as the fourth leading cause of cancer-related deaths worldwide. Despite recent advances in treatment options, a modest impact on the outcome of the disease is observed so far. We have previously demonstrated that short-term fasting cycles have the potential to improve the efficacy of chemotherapy against PC. The aim of this study was to assess the effect of an engineered resistant-starch (ERS) mimicking diet on the growth of cancer cell lines in vitro, on the composition of fecal microbiota, and on tumor growth in an in vivo pancreatic cancer mouse xenograft model...

Pd-Cu/palygorskite catalysts were prepared by a wet impregnation method using palygorskite (PC/N-Pal) and ultrasonic treated palygorskite (PC/U-Pal) as the support. Their catalytic activities toward CO oxidation at room temperature and in humid circumstances were investigated. PC/U-Pal exhibits much higher catalytic activity and stability than PC/N-Pal under the conditions of 1.0 vol.% CO and 3.3 vol.% H2O in the feed gas. The XRD results indicate that quartz impurities were eliminated from the palygorskite after the ultrasonic treatment, and more copper species exist in the form of Cu2Cl(OH)3 in PC/U-Pal...

Nitridosilicates represent an intriguing class of materials and are typically made up of highly condensed tetrahedral network structures. Alkaline-earth nitridosilicates emerged as unique host materials for Eu(2+) doped luminophores which found broad application in phosphor-converted (pc)-LEDs. In contrast to common strategies of preparing nitridosilicates by bottom-up syntheses, we have now succeeded to post-synthetically design nitridosilicates by ion exchange in metal halide melts. We describe the syntheses of hitherto unknown but predicted alkaline-earth nitridosilicates, Mg2 Si5 N8 and β-Ca2 Si5 N8 ...

Today, the functional and risk assessment of stenosed arteries is mostly based on ultrasound Doppler blood flow velocity measurements or catheter pressure measurements, which rely on several assumptions. Alternatively, blood velocity including turbulent kinetic energy (TKE) may be measured using MRI. The aim of the present study is to validate a TKE-based approach that relies on the fact that turbulence production is dominated by the flow's shear to determine the total irreversible energy loss from MRI scans...

Background.: The kidney plays a central role in elimination of metabolic waste products and regulation of low-molecular weight metabolites via glomerular filtration, tubular secretion and reabsorption. Disruption of these processes results in profound changes in the biochemical milieu of the body fluids, which contribute to complications of chronic kidney disease (CKD) by inducing cytotoxicity and inflammation. Insight into the changes of the composition of metabolites and dysregulation of target genes and proteins enhances the understanding of the pathophysiology of CKD and its complications, and the development of novel therapeutic strategies...

SUMMARYCluster of differentiation 36 (CD36) is a transmembrane protein that recognizes multiple diverse ligands. It is believed that (i) oxidized glycerophosphocholine species having a terminal γ-hydroxyl(or oxo)-α,β-unsaturated carbonyl on the sn-2 acyl group (oxGPCCD36), which can occur on the surface of lipoprotein particles, serve as high-affinity ligands for CD36, and (ii) the amino acid 150-168 of CD36 (CD36150-168) is responsible for recognizing oxGPCCD36. However, it remains uncertain whether CD36150-168 directly interacts with oxGPCCD36 alone...
