Subsequently, eight complete genome sequences were amplified using overlapping primers and sequenced.

Chlorogenic acid mitigates avian pathogenic Escherichia coli-induced intestinal barrier damage in broiler chickens via anti-inflammatory and antioxidant effects: CHLOROGENIC ACID AND BROILER CHICKENS.

This study was conducted to investigate the protective effects of chlorogenic acid (CGA) on intestinal health in broilers challenged with avian pathogenic Escherichia coli (APEC). One hundred and eighty one-day-old male broiler chicks were divided into three groups with six replicates of ten chicks each for a 21-day trial. The birds in the control and APEC groups were fed a basal diet, while birds in the CGA-treated group received a basal diet supplemented with 1000 mg/kg of CGA.

Prediction of acute toxicity of organic contaminants to fish: Model development and a novel approach to identify reactive substructures.

In this study, count-based Morgan fingerprints (CMF) were employed to represent the fundamental chemical structures of contaminants, and a neural network model (R² = 0.76) was developed to predict acute fish toxicity (AFT) of organic compounds. Models based on CMF consistently outperformed those based on binary Morgan fingerprints (BMF), likely due to the latter's inefficiency in describing homologous structures.

Spatiotemporal dissipation, metabolic dynamics and bumblebees' toxicity risk of the neonicotinoid insecticide thiacloprid in greenhouse conditions.

Some neonicotinoids have been restricted in outdoor environments due to their risks to pollinating insects, yet their safety for non-target organisms in greenhouses is still unknown.

Niche differentiation shaped the evolution of rhizobacterial antibiotic resistance in paddy fields: Evidences from spatial-temporal and chemical-biological scaling.

The rhizosphere serves as both a hotspot and an entry point for the proliferation and transformation of antibiotic resistance genes (ARGs). However, the ecological mechanisms governing the evolution of ARGs in rhizosphere soils remain poorly understood. This study showed that ARGs associated with efflux pumps were found to be significantly enriched in the rice rhizosphere, compared to bulk soils, with a deterministic assembly process.

Dendritic fibrous nanosilica supported Zn-based sorbents towards enhanced hot-coal-gas desulfurization: Structural design and metal modification.

Designing suitable carriers of sorbents for hot-coal-gas desulfurization is still a challenging task so far. In this study, dendritic fibrous nanosilica (DFNS) carriers with central radial pore structures were synthesized via microemulsion method, and the formation mechanism was proposed. The mean particle diameter (MPD) and mean surface wrinkle spacing (MSWS) of DFNS could be directionally controlled by regulating the emulsion phase behavior during DFNS synthesis.

Genome-wide identification of the HIPPs gene family and functional validation of MsHIPP12 in enhancing cadmium tolerance in Medicago sativa.

Heavy metal-associated isoprenylated plant proteins (HIPPs) are crucial for metal ion homeostasis and stress responses in plants exposed to heavy metals. They bind heavy metal ions via their HMA domains, sequestering them to prevent cellular toxicity. The C-terminal isoprenylation enhances interactions with membrane proteins, aiding in ion transport and compartmentalization.

Circadian rhythm modulation in heart rate variability as potential biomarkers for major depressive disorder: A machine learning approach.

Major depressive disorder (MDD) is associated with reduced heart rate variability (HRV), but its link to circadian rhythm modulation (CRM) of HRV is unclear. Given that depression disrupts circadian rhythms, assessing HRV fluctuations may better capture the CRM and the related autonomic nervous system (ANS) alterations, potentially enhancing our understanding of the pathophysiological mechanisms of MDD. This study aimed to explore the relationship between CRM of HRV and MDD, and to identify potential biomarkers for MDD using machine learning (ML).

Photoelectric activity of titania nanotube by dimensionality control for neural-stimulated osteoblast activation.

Simultaneous bone and nerve regeneration is important in facilitating osseointegration. However, regeneration of neural elements is often overlooked when designing orthopedic implants. Since nerves are electroactive tissues that regulate bone formation via neuropeptide release, developing photoelectric coating material on implants is optimal for neural-stimulated osteoblast activation.

Controlled-release of cinnamaldehyde from MXene/ZIF8/gelatin composite coatings: An integrated strategy to combat implant-associated infection.

Infections and chronic inflammation surrounding titanium implants frequently impair angiogenesis and osseointegration, substantially heightening the risk of implant failure. In this study, titanium dioxide nanotube arrays (TN) were fabricated on titanium metal substrates to serve as reservoirs for cinnamaldehyde (CA). Subsequently, MXene and ZIF-8 were deposited onto the TN surface to seal the nanotube pores.

Critical role of ferroptosis in viral infection and host responses.

Ferroptosis is an iron-dependent form of programmed cell death that plays a crucial role in regulating intracellular redox homeostasis and lipid metabolism, and in combating viral infections. Viruses have persistently evolved and adapted synergistically with their hosts over a long period and, to some extent, have been able to utilize ferroptosis to promote viral replication. Herein, we summarize the characteristics, mechanisms, and regulatory networks of ferroptosis and provide an overview of the key regulatory steps of ferroptosis involved in viral infection, together with the changes in host indicators and key regulatory signaling pathways.

Coinfection with bacterial pathogens and genetic modification of PRRSV-2 for suppression of NF-κB and attenuation of proinflammatory responses.

Porcine reproductive and respiratory syndrome virus (PRRSV) infects pulmonary alveolar macrophages and induces inflammation in the respiratory system. In swine farms, coinfection with PRRSV and bacterial pathogens is common and can result in clinically complicated outcomes, including porcine respiratory disease complex. Coinfection can cause excessive expressions of proinflammatory mediators and may lead to cytokine-storm-like syndrome.
