NYC Rats Are Even Grosser Than You Thought

Rats are a part of daily life in New York as they scurry about subway tracks and garbage heaps. However, even though the creatures been neighbors of New Yorkers for centuries, researchers are still learning exactly how these rodents could affect the health of millions. In a recently released study from scientists at Columbia University, researchers confirmed the fears of every New Yorker. These ubiquitous pests are housing dangerous bacteria including E. Coli, Salmonella and viruses including the deadly Seoul Hantavirus.

Al-Ghurabi, Shilpi Agarwal, Vinod Kumar Gupta Nanohydrogel of tragacanth gum using microwave radiations is used for the controlled release of ampicillin. Tragacanth gum was grafted with itaconic acid, employing graft copolymerization in the presence of N, N1–methylene-bis-acrylamide (MBA) as cross linker, and potassium persulphate as initiator. The prepared nanohydrogel was characterized using FTIR, XRD, SEM, and TEM. Besid...

Authors: Jung HK, Talley NJ Abstract Functional dyspepsia (FD) is a common disorder characterized by chronic epigastric pain or burning, or bothersome postprandial fullness or early satiation, without a definitive organic cause. The pathogenesis of FD is likely heterogeneous. Classically, motor disorders, visceral hypersensitivity, and brain-gut interactions have been implicated in the pathophysiology of FD, but recently an important role for chronic low-grade inflammation and post-infectious gastroenteritis in FD has been reported and confirmed. Duodenal low-grade inflammation is frequently observed in FD in those...

Series Type : Expression profiling by high throughput sequencingOrganism : Mus musculusPurpose: No gene expression profiles for the placenta in LPS-induced preterm labor mouse model have been published. The goal of this study was to obtain a comprehensive catalog of differentially expressed genes (DEGs) in the placenta using RNA-seq.Methods: Preterm labor mouse model (P) and control pregnancy group (C) were gained using a protocol from R. Migale, et al., BMC MED 14 (2016):86. Briefly, on day 15.5 of gestation, an abdominal minilaparotomy was performed. The upper right uterine horn between the first and second sacs received...

In this study, we investigated the chemical composition, and antioxidant and antibacterial properties of ethanolic extracts of propolis (EEP) from Melipona quadrifasciata quadrifasciata and Tetragonisca angustula. Chemical composition of EEP was determined by colorimetry and chromatographic (HPLC-DAD and UPLC-Q/TOF-MS/MS) analysis. Antimicrobial activity of EEP was evaluated against gram-positive (S. aureus, methicillin-resistant S. aureus, E. faecalis) and gram-negative (E. coli and K. pneumoniae) bacteria by the minimal inhibitory concentration (MIC) test using the microdilution method. Furthermore, the growth curve and ...

In this study, we used the yeast Pichia caribbica to degrade patulin effectively. The intermediate degradation products of patulin by P. caribbica were identified as (E)- and (Z)-ascladiol using high performance liquid chromatography and liquid chromatography-tandem mass spectroscopy. Only (E)-ascladiol was detected in the products of patulin degradation by intracellular enzymes. Toxic analyses on Escherichia coli Top10 cells, Arabidopsis thaliana, and human esophageal epithelial cells (Het-1a) showed that the intermediate degradation product ascladiol and the final degradation products were significantly less toxic and al...

Velthuis, G. van Schaik From 2009 to 2012 a gradual increase in on-farm mortality of Dutch veal calves was observed. In 2012, the cattle industry decided that more information was needed on risk factors for mortality in both veal herds and herds of origin to enable implementation of risk mitigating measures. Routinely collected data were available from seven different data sources and contained information from 2.4 million white veal calves that were fattened ...

However, the conventional exfoliation strategy is incapable for fast and clean preparation of such highly-quality g-C3N4 nanosheets from their bulk-type counterparts. Herein, highly-crystalline few-layer g-C3N4 nanosheets were synthesized only within 10...

Fomites are reservoirs of drug-resistant pathogens found in the unhygienic clinical environment, which can infect patients and leading to high nosocomial infection rates and use of antimicrobial drugs. The use of and search for drugs and dietary supplements derived from plants have accelerated various therapeutic app...

Chehimi The efficacy of surfactants in stabilizing CuO-NPs onto the surface of the cotton fibers and their ability to produce homogeneous CuO-coated cotton composite was studied using different types of surfactants. The use of surfactants provides better adhesion of the CuO NPs and consequence, enhanced its coating stability during exploitation. The optical structure and morphology of the coated cotton fabrics were examined by sev...
