Summary We evaluated the population structure and temporal dynamics of dominant community members within sewage influent from two wastewater treatment plants (WWTPs) in Milwaukee, WI. generated > 1.1 M bacterial pyrotag sequences V6 hypervariable region 16S rRNA genes 38 samples taken upstream sanitary sewer system. Only a small fraction pyrotags (∼ 15%) matched human faecal samples. The components included enriched populations Lactococcus Enterobacteriaceae relative to their fractional...

The increasing abundance of fine particulate matter (PM2.5) in the environment has increased susceptibility to acute exacerbation COPD (AECOPD). During PM2.5 exposure, excessive reactive oxygen species (ROS) production triggers a redox imbalance, which contributes damage organelles and disruption homeostasis. At present, there are limited data on whether NOX4/Nrf2 imbalance increases (AECOPD), underlying mechanism is unclear. Therefore, current study was aimed evaluate role balance AECOPD...

How different stress responses by male and female plants are influenced interactions with rhizosphere microbes remains unclear. In this study, we employed poplar as a dioecious model plant quantified biotic associations between microorganisms to explore the relationship microbial adaptation. We propose health index (HI) comprehensively characterize physiological characteristics adaptive capacity of under stress. It was found that poplars demonstrated higher salt tolerance than females,...

Abstract The prevalence of TW I-type infectious bronchitis virus (IBV) has been increasing rapidly, and it become the second most common genotype IBV in China threatening poultry industry. In this study, 1-day-old specific-pathogen-free (SPF) chickens infected with were continuously observed for 200 days. affected respiratory, urinary, female reproductive systems, resulting a mortality rate 10% as well decrease egg quantity an increase inferior eggs. During monitoring period, serious lesions...

The QX-type infectious bronchitis virus (IBV) has become the predominant genotype worldwide in recent years and caused serious economic losses to chicken industry. most significant feature of QX IBV is that its infection early growing stage can cause abnormal oviduct development, resulting a high proportion 'false layers' poultry flocks laying hens breeders. However, few studies have evaluated whether infections stages also severe pathological changes oviduct.In this study, 300-day-old...

Abstract Sexual dimorphism of plants shapes the different morphology and physiology between males females. However, it is still unclear whether influences belowground ecological processes. In this study, rhizosphere soil male female Populus deltoides bulk were collected from an 18-year plantation (male trees mix-planted) grouped into three compartments. Soil carbon (C), nitrogen (N) phosphorus (P) levels determined, bacterial communities analyzed by high-throughput sequencing. The results...

Since its discovery, QX-type avian infectious bronchitis virus (IBV) has rapidly spread worldwide and become the most prevalent dominant genotype in Asia Europe. Currently, although pathogenicity of IBV reproductive system hens is widely deeply understood, roosters remains largely unknown. In this study, 30-week-old specific pathogen-free (SPF) were used to investigate after infection. The results showed that infection caused abnormal testicular morphology, moderate atrophy obvious...

Oxidative stress and inflammation play important roles in pleurisy. Leonurine (Leo) has been confirmed to exert antioxidative antiinflammatory effects many preclinical experiments, but these have not studied The aim of this study was explore the therapeutic effect mechanism Leo a carrageenan (CAR)-induced pleurisy model. In study, we found that increase reactive oxygen species (ROS), myeloperoxidase (MPO), malondialdehyde (MDA) decrease glutathione (GSH) induced by CAR could be reversed...

Abstract Background Lignin’s valorization plays a critical role in refining the bioresource. Considering that β-aryl ether linkage (β-O-4 bond) accounts for 50–70% of lignin chemical between aromatic rings, hydrolase linkage, especially β -etherase, provided promising way depolymerization and valorization. As result, it is essential to develop effective high-throughput methods screening mutant library -etherase from directed evolution. Results Based on enzymatic mechanism β-O-4 bond’s...

The interaction between plants and microbes dominates plant growth fitness in specific environments. study of the relationship genotypes rhizobacterial community structure would provide a deep insight into recruitment strategies toward soil bacteria. In this study, three 18-year-old mature poplar (H1, H2, H3) derived from four different parents were selected germplasm nursery Populus deltoides. Rhizosphere carbon, nitrogen, phosphorus properties as well 16S rDNA sequences communities...
