A novel pH-sensitive antibacterial bilayer film for intelligent packaging.

Intelligent single-layer packaging is widely used in food monitoring and storage. However, most single-layer intelligent packaging has poor mechanical strength and water barrier properties. In this study, a bilayer intelligent detector film based on polyvinyl alcohol-chitosan (PVA-CS)/nano-ZnO/sodium alginate (SA) combined with anthocyanin extract (cyanidin chloride) was prepared using a layer-by-layer solution casting assembly technique.

Anchoring black phosphorous quantum dots on BiWO porous hollow spheres: A novel 0D/3D S-scheme photocatalyst for efficient degradation of amoxicillin under visible light.

Reasonable regulation of the micro-morphology of material can significantly enhance the related performance. Herein, bismuth tungstate (BiWO, simplified as BWO) porous hollow spheres with flower-like surface were prepared successfully, and this unique morphology endowed BWO with improved photocatalytic performance by reflecting and absorbing the light multiple times inside the cavity. To inhibit the rapid recombination of photogenerated e-h pairs within BWO itself, black phosphorous quantum dots (BPQDs) were anchored onto the nanosheets of BWO sphere closely by a facile self-assembly process, which will not shade the pores of BWO owing to the small size of BPQDs, but the BP nanosheets have the chance to do that.

Mutual interaction between endoplasmic reticulum and mitochondria in nonalcoholic fatty liver disease.

Nonalcoholic fatty liver disease (NAFLD) is a common metabolic syndrome. Imbalances between liver lipid output and input are the direct causes of NAFLD, and hepatic steatosis is the pathological premise and basis for NAFLD progression. Mutual interaction between endoplasmic reticulum stress (ERS) and oxidative stress play important roles in NAFLD pathogenesis.

Beneficial Metabolic Effects of Chitosan and Chitosan Oligosaccharide on Epididymal WAT Browning and Thermogenesis in Obese Rats.

Many anti-obesity chemicals have been withdrawn from the market due to serious adverse reactions, and the researchers have turned their attention to low-toxic natural products. Previous studies have demonstrated that chitosan (CTS) and chitosan oligosaccharide (COS) were low-toxic natural products for the use of weight loss. However, it is still unclear whether CTS and COS have positive effects on the thermogenesis.

Modulation effect of vaginal mucosal microflora and susceptibility to Neisseria gonorrhoeae infections: a systematic review and meta-analysis.

Objective: The vaginal microbiota may modulate susceptibility to Neisseria gonorrhea (NG) infections. The objective of this meta-analysis was to evaluate the association between these NG infections and the vaginal microbiota.

Method: A systematic review and meta-analysis was conducted to investigate the correlation of vaginal microbiota and NG risk.

Over reporting of congenital syphilis in Guangzhou, China.

The purpose of this study was to evaluate the rationality of congenital syphilis (CS) cases reported by physicians in hospitals of various levels in Guangzhou, China. The over-reporting rate was calculated. The results suggested that 49.

Awareness and knowledge of syphilis among different populations in Guangzhou, Guangdong Province, China.

The purpose of this study was to investigate the awareness of different populations about syphilis in Guangzhou, the capital city of Guangdong Province, China. A questionnaire survey was conducted, and awareness rates of different groups were calculated. The results suggested that the awareness rates of syphilis knowledge in the surveyed subjects were low, and targeted health education and health promotion should be strengthened.

Double-minute MYC amplification and deletion of MTAP, CDKN2A, CDKN2B, and ELAVL2 in an acute myeloid leukemia characterized by oligonucleotide-array comparative genomic hybridization.

Chromosomal analysis and fluorescence in situ hybridization (FISH) have been routinely used in detecting recurrent chromosomal abnormalities in patients with various hematological malignancies. However, the genomic imbalances underlying many recurrent abnormalities could not be delineated due to the low resolution of chromosome analysis. We have performed oligonucleotide-array comparative genomic hybridization (oaCGH) in an AML case with a 15p/17p translocation, a suspected 9p21 deletion, monosomies of chromosomes X and 9, and 2 to 60 double minutes.
