Hierarchical assembly and modeling of DNA nanotube networks using Y-shaped DNA origami seeds.

DNA nanotechnology offers many means to synthesize custom nanostructured materials from the ground up in a hierarchical fashion. While the assembly of DNA nanostructures from small (nanometer-scale) monomeric components has been studied extensively, how the hierarchical assembly of rigid or semi-flexible units produces multi-micron scale structures is less understood. Here we demonstrate a mechanism for assembling micron-scale semi-flexible DNA nanotubes into extended structures.

SW207 alleviates enterotoxigenic -induced inflammatory responses in weaned piglets by modulating the intestinal epithelial barrier, the TLR4/MyD88/NF-κB pathway, and intestinal microbiota.

Enterotoxigenic (ETEC) is one of the major pathogens contributing to piglet diarrhea, with significant implications for both piglet health and the economic aspects of the livestock industry. SW207 is an isolate of isolated from the cold- and disease-resistant Leixiang pigs in Northeastern China. We have discovered that SW207 can survive in the pig's gastrointestinal fluid and under conditions of high bile salt concentration, displaying potent antagonistic activity against ETEC.

Heavy metal migration dynamics and solid-liquid distribution strategy in abandoned tailing soils.

The tailings soil originating from an abandoned sulfur-iron mine in Sichuan Province, China, exhibits elevated concentrations of heavy metals (HMs) and possesses limited soil conservation capacity. Variability soil particle size fractions (PSFs) contributes to an increased risk of HMs ion migration. Existing research on HMs behavior has focused on the bulk soil scale, resulting in a dearth of comprehensive information concerning different particle sizes and colloid scales.

Neonicotinoids residues in cow milk and health risks to the Chinese general population.

The application of neonicotinoid insecticides (NEOs) has increased dramatically in the world since being introduced in 1990s, yet the extent of human exposure and potential health risk is not fully unraveled. In this study, the residues were analyzed of 16 NEOs and their metabolites in 205 commercial cow milk samples circulating in Chinese market. All the milk samples contained at least one quantified NEO, and over 90% of samples contained a cocktail of NEOs.

The consumption of chili peppers and the risk of colorectal cancer: a matched case-control study.

Background: Chili peppers have properties that plausibly could either increase or decrease a person's risk of developing colorectal cancer, but their consumption in relation to disease risk has not been well studied. We sought to explore the association between chili peppers intake and the risk of colorectal cancer.

Methods: Eight hundred subjects (400 cases with colorectal cancer and 400 controls) were enrolled in this study.

[Association of rs659366 polymorphisms with the outcomes of patients after surgery for colorectal cancer].

Objective: To explore the association between rs659366 polymorphisms and the outcomes of patients after surgery for colorectal cancer.

Methods: The study was conducted among a cohort of 501 patients with primary colorectal cancer who had surgery in Sichuan Cancer Hospital during March 2010 and July 2013. The outcomes of the patients were followed up.

Fabrication and molecular dynamics analyses of highly thermal conductive reduced graphene oxide films at ultra-high temperatures.

Thin films with high thermal conductivity are urgently needed as heat dissipation materials for electronic devices. In this study, we developed a readily scalable roller coating method followed by ultra-high temperature annealing to prepare large-sized, free-standing, and flexible reduced graphene oxide (rGO) films with high thermal conductivity. The in-plane thermal conductivity measured by a laser flash method for the sample annealed at 2800 °C was 826.
