Perceptual image quality metrics have explicitly accounted for human visual system (HVS) sensitivity to subband noise by estimating just noticeable distortion (JND) thresholds. A recently proposed class of metrics, known as structural similarity (SSIM), models perception implicitly taking into account the fact that HVS is adapted extracting information from images. We evaluate SSIM and compare their performance traditional approaches in context realistic distortions arise compression error...

Vibrio cholerae quorum sensing controls expression of four redundant sRNAs, Qrr1-4. The Qrr sRNAs are predicted to alter the translation several mRNAs, including, hapR, which encodes a transcription factor that genes for virulence factors, biofilm formation, protease production and DNA uptake. Each contains 21 nucleotide region absolutely conserved among pathogenic Vibrios, base pair with mRNA targets, like aided by RNA chaperone Hfq. This molecular mechanism was not experimentally tested...

A total of 154 non-duplicate Salmonella isolates were recovered from 1,105 rectal swabs collected three large-scale chicken farms (78/325, 24.0%), duck (56/600, 9.3%) and pig (20/180, 11.1%) between April July 2016. Seven serotypes identified among the isolates, with most common serotype in chickens ducks being enteritidis pigs typhimurium. Antimicrobial susceptibility testing revealed that high antimicrobial resistance rates observed for tetracycline (72.0%) ampicillin (69.4%) all sources....

The liver plays a central role in cholesterol homeostasis. It exclusively receives and metabolizes oxysterols, which are important metabolites of more cytotoxic than free cholesterol, from all extrahepatic tissues. Hepatocellular carcinomas (HCCs) impair certain functions cause pathological alterations many processes including metabolism. However, the link between an altered metabolism HCC development is unclear. Human ACAT2 abundantly expressed intestine fetal liver. Our previous studies...

Gallbladder cancer (GBC) is the most common malignancy in biliary tract with poor prognosis. Due to its high chemoresistance, systemic chemotherapies have had limited success treating GBC patients. MicroRNAs (miRNAs) are emerging novel regulators of which modulate expression drug resistance-related genes. In this study, we investigated association between miR-145 and cisplatin sensitivity by both vivo vitro analysis. Quantitative PCR (q-PCR) analysis indicated an increased tissues. addition,...

Abstract Dysembryoplastic neuroepithelial tumors (DNT) lacking key diagnostic criteria are challenging to diagnose and sometimes fall into the broader category of mixed neuronal-glial (MNGT) or recently described polymorphous low-grade tumor young (PLNTY). We examined 41 patients with DNT, MNGT, PLNTY for histologic features, genomic findings, progression-free survival (PFS). Genomic analysis included sequence copy number variants RNA-sequencing. Classic DNT (n = 26) was compared those...

This study was aimed to investigate the effects of Clostridium butyricum (C. butyricum) immunity and intestinal epithelial barrier function at mucosal level, by using Salmonella enteritidis (S. enteritidis) infect specific-pathogen-free (SPF) chickens cells (IEC). We found that C. could decrease cytokine levels (IFN-γ, IL-1β, IL-8 TNF-α) via TLR4-, MyD88-, NF-κB-dependent pathways in tissues cells. Additionally, attenuate bacteria-induced damage increase expression level muc-2 ZO-1 intestine...

Spammers are constantly creating sophisticated new weapons in their arms race with anti-spam technology, the latest of which is image-based spam. The newest spam uses simple image processing technologies to vary content individual messages, e.g. by changing foreground colors, backgrounds, font types, or even rotating and adding artifacts images. Thus, they pose great challenges conventional filters. In this paper, we propose a system using probabilistic boosting tree determine whether an...
