Transcriptomics Reveals the Killing Mechanism by Which Entomopathogenic Fungi Manipulate the RNA Expression Profiles of Termites and Provides Inspiration for Green Pest Management.

As chemical pesticides have caused serious environmental pollution, fungus-based biological control has become a developing alternative to chemical control. Here, we aimed to determine the molecular mechanism underlying how facilitated invasive infection. We found that the fungus increased its virulence by downregulating () and () throughout termite bodies.

Reconstruction of polarization images from a multimode light-field imaging system.

The multimode light-field camera can capture spatial location and spectral and polarization characteristics of a target simultaneously. There is an aliasing effect, which causes the directly extracted image of a certain filter to include information from other filters. The reconstruction method proposed by Li (Jingzhen Li, thesis of Beihang University, 2015) can improve the accuracy of the polarization images, but the gray values still have gradient variations.

The toll-like receptor 4 antagonist transforming growth factor-β-activated kinase(TAK)-242 attenuates taurocholate-induced oxidative stress through regulating mitochondrial function in mice pancreatic acinar cells.

Background: Acute pancreatitis (AP) is a commonly occurring and potentially life-threatening disease. Recently, toll-like receptor 4 (TLR4) has been considered as a new clue for studying the pathogenesis of AP due to its important role in inflammatory response cascade.

Materials And Methods: The aim of this study was to investigate the potential protective effect of transforming growth factor-β-activated kinase (TAK)-242, a novel TLR4 antagonist, in taurocholate-treated mice pancreatic acinar cells.

Comparative Gut Microbiomes of Four Species Representing the Higher and the Lower Termites.

Aiming at learning the association between the gut microbiota and termites with different diet habits and phylogenetic positions, the gut bacteria of three populations for each of the two higher termites (wood-feeding Mironasutitermes shangchengensis and fungus-feeding Odontotermes formosanus) and two wood-feeding lower termites (Tsaitermes ampliceps and Reticulitermes flaviceps) were analyzed by high-throughput 454 pyrosequencing of 16S V1-V3 amplicons. As results, 132 bacterial genera and some unidentified operational taxonomic units within 29 phyla in the gut bacteria were detected, with Spirochaetes (11-55%), Firmicutes (7-18%), Bacteroidetes (7-31%), and Proteobacteria (8-14%) as the main phyla, and Treponema, TG5, Dysgonomonas, Tannerella, za29, Lactococcus, Pseudomonas, and SJA-88 as the common genera in all the four termites. The diversity of gut bacterial communities in the higher termite guts was significantly greater than that in the lower termites; while the gut microbiota in M.

Molecular epidemiology of PRRSV from China's Guangxi Province between 2007 and 2009.

Porcine reproductive and respiratory syndrome (PRRS) is considered to be one of the most important infectious diseases affecting livestock. This study used gene sequence analysis of ORF5 and Nsp2 to determine the molecular epidemiology of PRRSV in different parts of the Guangxi province of China. These genes were selected due to their extensive variation within the genome.

In vitro infection with classical swine fever virus inhibits the transcription of immune response genes.

Background: Classical swine fever virus (CSFV) can evade the immune response and establish chronic infection under natural and experimental conditions. Some genes related to antigen processing and presentation and to cytokine regulation are known to be involved in this response, but the precise mechanism through which each gene responds to CSFV infection remains unclear.

Results: In this study, the amplification standard curve and corresponding linear regression equations for the genes SLA-2, TAP1, SLA-DR, Ii, CD40, CD80, CD86, IFN-α, and IFN-β were established successfully.

Galangin induces apoptosis in hepatocellular carcinoma cells through the caspase 8/t-Bid mitochondrial pathway.

This study has investigated whether galangin, a flavonol derived from Alpinia officinarum Hance and used as food additives in southern China, induces apoptosis in hepatocellular carcinoma cells (HCCs) by activation of the caspase-8 and Bid pathway. The apoptosis of HCCs was evaluated by in situ uptake of propidium iodide and Hoechst 33258. Protein expressions were detected by Western blotting.

Protective effect of supplemental anthocyanins on Arabidopsis leaves under high light.

Ten anthocyanin components have been detected in roots of purple sweet potato (Ipomoea batatas Lam.) by high-performance liquid chromatography coupled to diode array detection and electrospray ionization tandem mass spectrometry. All the anthocyanins were exclusively cyanidins or peonidin 3-sophoroside-5-glucosides and their acylated derivatives.

Expression patterns and action analysis of genes associated with hepatitis virus infection during rat liver regeneration.

Aim: To study the action of hepatitis virus infection-associated genes at transcription level during liver regeneration (LR).

Methods: Hepatitis virus infection-associated genes were obtained by collecting the data from databases and retrieving the correlated articles, and their expression changes in the regenerating rat liver were detected with the rat genome 230 2.0 array.

[Analysis of changes about hsbp1, hsf1, hsf2 AND hsp70's expression levels in rat's regenerating liver].

Heat shock factor binding protein 1 (HSBP1), a recently discovered protein, weakens and blocks transcription of the heat shock protein 70 (HSP70) gene when binding to HSF1, but HSBP1 can promote cell growth, cell development and cell differentiation when binding to HSF2. Partial hepatectomy (PH) in rat creates injury stimulation and induces liver regeneration. How does hsbp1 coordinate two processes sequently is extremely interesting.
