Bimetallic Au and Pd Nanoparticles Modified WO Nanosheets for Enhancing the Sensitivity and Selectivity of Formaldehyde Assessment in Aquatic Products.

Formaldehyde, a common illegal additive in aquatic products, poses a threat to people's health and lives. In this study, a novel metal oxide semiconductor gas sensor based on AuPd-modified WO nanosheets (NSs) had been developed for the highly efficient detection of formaldehyde. WO NS modified with 2.

Molecular characteristics of gastric cancer with amplification.

Gastric cancer is a prevalent malignancy with a high degree of heterogeneity, which has led to a poor therapeutic response. Though there are numerous HER2-targeted medicines for HER2+ gastric cancer, many trials have not indicated an improvement in overall survival. Here 29 amplification (-Amp) type gastric cancer samples with WES and RNA-seq data were selected for investigation, which copy-number aberration (CNA) was +2.

Self-Assembling Cyclodextrin-Based Nanoparticles Enhance the Cellular Delivery of Hydrophobic Allicin.

Most chemotherapeutics are hydrophobic molecules and need to be converted into hydrophilic formulations before administration. To address this issue, a novel cyclodextrin-based nanoparticle was proposed as a versatile carrier for cellular delivery of hydrophobic molecules. First, the effect of the polylysine (PL)/NH-β-cyclodextrin (NH-β-CD) ratio on particle size and encapsulation efficiency in prepared complexes was investigated.

Allicin Regulates Energy Homeostasis through Brown Adipose Tissue.

Brown adipose tissue (BAT) is a promising potential therapeutic target for the treatment of obesity and related metabolic diseases. Allicin, a natural product in garlic, has multiple biological and pharmacological functions. However, the role of allicin in the regulation of metabolic organs, particularly BAT activation, has not been well studied.

Reduced adiposity by compensatory WAT browning upon iBAT removal in mice.

The strong effects of classic brown adipose tissue (BAT) and recruited beige adipocytes in treatment of obesity and metabolic syndrome have been attracting increasing research interest. Cold treatment is an effective, convenient approach to stimulate BAT activity and induce white adipose tissue (WAT) browning. Here, we utilized prolonged cold exposure (from 2 h to 2 weeks in a 4° cold chamber) to elucidate dynamic changes in BAT and in WAT browning during acute and chronic cold exposure in mice.

Hypoglycemic and hypolipidemic effect of S-allyl-cysteine sulfoxide (alliin) in DIO mice.

Alliin (S-allyl cysteine sulfoxide) is a bioactive sulfoxide compound derived from garlic. To evaluate the preventive effect of alliin against metabolic risk factors in diet induced obese (DIO) mice, we treated the C57BL/6J DIO mice with drinking water with or without alliin (0.1 mg/ml) for 8 weeks.

A Viral Satellite DNA Vector (TYLCCNV) for Functional Analysis of miRNAs and siRNAs in Plants.

With experimental and bioinformatical methods, numerous small RNAs, including microRNAs (miRNAs) and short interfering RNAs (siRNAs), have been found in plants, and they play vital roles in various biological regulation processes. However, most of these small RNAs remain to be functionally characterized. Until now, only several viral vectors were developed to overexpress miRNAs with limited application in plants.

Rutin ameliorates obesity through brown fat activation.

Increasing energy expenditure through activation of brown adipose tissue (BAT) is a critical approach to treating obesity and diabetes. In this study, rutin, a natural compound extracted from mulberry and a drug used as a capillary stabilizer clinically for many years without any side effects, regulated whole-body energy metabolism by enhancing BAT activity. Rutin treatment significantly reduced adiposity, increased energy expenditure, and improved glucose homeostasis in both genetically obese (Db/Db) and diet-induced obesity (DIO) mice.

MicroRNA profiling analysis throughout tomato fruit development and ripening reveals potential regulatory role of RIN on microRNAs accumulation.

The development and ripening of tomato fruit are complex processes involving many gene regulatory pathways at the transcriptional and post-transcriptional level. Ripening inhibitor (RIN) is a vital transcription factor, which targets numerous ripening-related genes at the transcriptional level during tomato fruit ripening. MicroRNAs (miRNAs) are a class of short noncoding RNAs that play important roles in post-transcriptional gene regulation.

SRNAome parsing yields insights into tomato fruit ripening control.

Small RNAs have emerged as critical regulators in the expression and function of eukaryotic genomes at the post-transcriptional level. To elucidate the functions of microRNA (miRNAs) and endogenous small-interfering RNAs (siRNAs) in tomato fruit ripening process, the deep sequencing and bioinformatics methods were combined to parse the small RNAs landscape in three fruit-ripening stages (mature green, breaker and red-ripe) on a whole genome. Two species-specific miRNAs and two members of TAS3 family were identified, 590 putative phased small RNAs and 125 cis-natural antisense (nat-siRNAs) were also found in our results which enriched the tomato small RNAs repository and all of them showed differential expression patterns during fruit ripening.

A universal primer multiplex PCR method for typing of toxinogenic Pseudomonas aeruginosa.

Pseudomonas aeruginosa is a well-known opportunistic pathogen that can cause acute nosocomial necrotizing pneumonia and genetic disorder cystic fibrosis of lung patients. Pathogenic interactions between P. aeruginosa and hosts are often guided by the secreted virulence determinants that interact with specific host targets.

Sculpting the maturation, softening and ethylene pathway: the influences of microRNAs on tomato fruits.

Background: MicroRNAs (miRNAs), a ubiquitous class of short RNAs, play vital roles in physiological and biochemical processes in plants by mediating gene silencing at post-transcriptional (PTGS) level. Tomato is a model system to study molecular basis of fleshy fruit ripening and senescence, ethylene biosynthesis and signal transduction owing to its genetic and molecular tractability. To study the functions of miRNAs in tomato fruit ripening and senescence, and their possible roles in ethylene response, the next generation sequencing method was employed to identify miRNAs in tomato fruit.

MicroRNAs in tomato plants.

MicroRNAs (miRNAs) are a specialized class of small silencing RNAs that regulate gene expression in eukaryotes. In plants, miRNAs negatively regulate target mRNAs containing a highly complementary sequence by either mRNA cleavage or translational repression. As a model plant to study fleshy fruit ripening, miRNA studies in tomato have made great progress recently.
