Dietary Quercetin Regulates Gut Microbiome Diversity and Abundance in (Hymenoptera Apidae).

Honeybee gut microbiota plays a crucial role in maintaining their health and digestive function. Studies have confirmed that quercetin improves honeybee health by enhancing their pesticide tolerance and survival rates. This study aimed to examine the effects of quercetin on the bee gut microbiome by absolute quantification sequencing.

Generating diagnostic report for medical image by high-middle-level visual information incorporation on double deep learning models.

Background And Objectives: Writing diagnostic reports for medical images is a heavy and tedious work. The automatic generation of medical image diagnostic reports can assist doctors to reduce their workload and improve diagnosis efficiency. It is of great significance to introduce image caption algorithm into medical image processing.

Candidate chemosensory genes identified from the greater wax moth, Galleria mellonella, through a transcriptomic analysis.

The greater wax moth, Galleria mellonella Linnaeus (Lepidoptera: Galleriinae), is a ubiquitous pest of the honeybee, and poses a serious threat to the global honeybee industry. G. mellonella pheromone system is unusual compared to other lepidopterans and provides a unique olfactory model for pheromone perception.

Prevalence and genome characteristics of canine astrovirus in southwest China.

The aim of this study was to investigate canine astrovirus (CaAstV) infection in southwest China. We collected 107 faecal samples from domestic dogs with obvious diarrhoea. Forty-two diarrhoeic samples (39.

Design, synthesis and biological evaluation of 1H-pyrrolo[2,3-b]pyridine and 1H-pyrazolo[3,4-b]pyridine derivatives as c-Met inhibitors.

Five novel 1H-pyrrolo[2,3-b]pyridine or 1H-pyrazolo[3,4-b]pyridine derivatives, with a methylene, sulfur, sulfoxide or cyclopropyl group as a linker, were designed, synthesized and biologically evaluated against c-Met and ALK. The development of these methods of compound synthesis may provide an important reference for the construction of novel 7-azaindole and 7-azaindazole derivatives with a single atom linker. The enzyme assay and cell assay in vitro showed that compound 9 displayed strong c-Met kinase inhibition with IC50 of 22.

Synthesis and anticancer activities of novel 1,2,4-triazolo[3,4-a]phthalazine derivatives.

Trying to develop potent and selective anticancer agents, two series of novel 1,2,4-triazolo[3,4-a]phthalazine derivatives were designed and synthesized. Their antitumor activities were evaluated by MTT method against four selected human cancer cell lines (MGC-803, EC-9706, HeLa and MCF-7). Our results showed that compound 11h exhibited good anticancer activities compared to 5-fluorouracil against the four tested cell lines, with IC50 values ranging from 2.
