Peroxisome proliferator activated receptor-alpha (PPARα) and Egl nine homolog 3 (EGLN3) play critical roles in facilitating the adaptation to a hypoxic environment. However, the relationship between EGLN3 and PPARα variants and hypoxic adaptation remains poorly understood in Tibetan chickens. To better understand the effects of genetic variation, we sequenced exons of PPARα and EGLN3 in 138 Lowland chickens (LC) from 7 breeds that were located in Emei, Miyi, Shimian, Wanyuan, Pengxian, and Muchuan in the Sichuan province, and Wenchang in the Hainan province (altitudes for these locations are below 1800 meters)...

The constant failure of single-target drug therapies for ischemic stroke necessitates the development of novel pleiotropic pharmacological treatment approaches, to effectively combat the aftermath of this devastating disorder. The major objective of our study involves a multi-target drug repurposing strategy to stabilize hypoxia-inducible factor-1 α (HIF-1α) via a structure-based screening approach to simultaneously inhibit its regulatory proteins, PHD2, FIH, and pVHL. Out of 1424 Food and Drug Administration (FDA)-approved drugs that were screened, folic acid (FA) emerged as the top hit and its binding potential to PHD2, FIH, and pVHL was further verified by re-docking, molecular dynamics (MD) simulation and by Drug Affinity Responsive Target Stability (DARTS) assay...

Realgar (As4 S4 ), as an arsenic sulfide mineral drug, has a good therapeutic reputation for anticancer in Traditional Chinese Medicine, and has recently been reported to inhibit angiogenesis in tumor growth. However, considering the poor solubility and low bioavailability of realgar, large dose of realgar and long period of treatment are necessary for achieving the effective blood medicine concentration. In present study, we resolved the crucial problem of poor solubility of realgar by using intrinsic biotransformation in microorganism, and investigated underlying mechanisms of realgar transforming solution (RTS) for antiangiogenesis...

Oxidative stress is an important inducement in ovarian aging which results in fecundity decline in human and diverse animals. As a potent antioxidant, grape seed proanthocyanidin extract (GSPE) was investigated to ameliorate chicken ovarian aging in this study. Firstly, ovarian antioxidant capacity of hens at different ages (90, 150, 280, and 580 days old) was compared to elucidate its age-related changes. Subsequently, a D-gal-induced (2.5 mg/mL) aging ovarian model was established and the cultured ovarian tissues were treated with GSPE at 5  μ g/mL for 72 h to evaluate the putative attenuating effects of GSPE on ovarian aging...

Broiler chickens are increasingly at the forefront of global meat production but the consequences of fast growth and selection for an increase in body mass on bird health are an ongoing concern for industry and consumers. To better understand the implications of selection we evaluated energetics and behaviour over the 6-week hatch-to-slaughter developmental period in a commercial broiler. The effect of posture on resting metabolic rate becomes increasingly significant as broilers grow, as standing became more energetically expensive than sitting...

By assisting in the proteolysis, disaggregation and refolding of the aggregated proteins, Caseinolytic proteases (Clps) enhance the cellular survival under stress conditions. In the current study, comparative roles of two such Clps, ClpA (involved in proteolysis) and ClpB (involved in protein disaggregation and refolding) in the survival of Salmonella Typhimurium (S. Typhimurium) under different stresses and in virulence have been investigated. clpA and clpB gene deletion mutant strains (∆clpA and ∆clpB) of S...

Infectious bursal disease virus (IBDV) belongs to the Birnaviridae family and is the etiological agent of a highly contagious and immunosuppressive disease (IBD) that affects domestic chickens ( Gallus gallus ). IBD or Gumboro disease leads to high morbidity and mortality of infected animals, and is responsible for major economic losses to the poultry industry world-wide. IBD is characterized by a massive loss of IgM-bearing B lymphocytes and the destruction of the bursa of Fabricius. The molecular bases of the IBDV pathogenicity are still poorly understood, nonetheless, an exacerbated cytokine immune response and B cell depletion due to apoptosis are considered main factors contributing to the severity of the disease...

Birnaviruses are unconventional members of the double-stranded RNA (dsRNA) viruses group that are characterized by the lack of a transcriptionally active inner core. Instead, the birnaviral particles organize their genome in ribonucleoprotein complexes (RNPs) composed by dsRNA segments, the dsRNA-binding VP3 protein, and the viral encoded RNA-dependent RNA-polymerase (RdRp). This and other structural features suggests that birnaviruses may follow a completely different replication program from that followed by members of the Reoviridae family, supporting the hypothesis that birnaviruses are the evolutionary link between single-stranded positive RNA (+ssRNA) and dsRNA viruses...

Historically, fowl adenovirus (FAdV) associated inclusion body hepatitis (IBH) was considered a secondary disease in broiler chickens associated with immunosuppression. However, we previously reported the occurrence of IBH as a primary disease in the broiler chicken industry in Canada as a result of infections with various FAdV serotypes. Therefore, the objectives of this study were to develop an immunization strategy in broiler breeders using live FAdV 11-1047 and FAdV8a-TR59 to confer homologous and heterologous protection in broiler progeny against IBH and to study the efficacy of natural exposure of naïve broiler breeders to a vaccine virus from live FAdV vaccinated birds as an immunization technique...

Three hundred birds (1 day old) were randomly assigned to 6 groups (n = 50 birds/treatment) and fed a basal diet (control) or basal diet supplemented with Allium hookeri (AH) root (1 or 3%). At day 14, half of the birds in each group were orally challenged with E. maxima 41A (1 × 104 cells/chicken), followed by C. perfringens infection (1 × 109 cfu/chicken) on day 18. Necrotic enteritis (NE)-associated infections and intestinal immune response were assessed by average body weight gain, lesion score, and oocyst shedding...

Poultry production is among the most rapidly growing industries around the globe, and poultry is one of the major sources of meat. Poultry farmers use disease preventive and growth promoter antibiotics for faster growth of chickens in the shortest possible time to increase the rate of feed assimilation and to lower the incidence of mortality caused by a pathogen attack. Antibiotics may result in dysfunctionality of beneficial gut microbiota and increase resistance among microbial pathogens in poultry. Residues of these antibiotics in poultry meat have been determined in many of the studies globally and are considered one of the possible causes of antibacterial resistance in human pathogens...

PURPOSE: To characterize and suppress stripe artifact associated with velocity-selective (VS) magnetization for unenhanced MRA. METHODS: Extended phase graph formalism was used to show that the stripe artifact contains multiples of the fundamental frequency that is determined by the area of unipolar VS gradient. Four VS preparation pulses whose excitation profiles are spatially shifted by quarter the fundamental period of the stripes, were applied alternately. For further suppression of the artifact, k-space data at kz  = 0 were averaged over the 4 VS preparations...

The breeding of wild birds in captivity assumes an increasingly important role in conservation due to the loss of species and their habitats. Providing the environmental and nutritional needs of species kept in captivity is the key for achieving success in such initiatives. Among the flock health practices, we highlight here wild bird vaccination, a scarcely studied subject. This study clinically and serologically evaluates the effect of applying a vaccination protocol against Newcastle disease in three groups of ornamental wild birds...

Traditional approaches to assess the immune response of chickens to infection are through animal trials, which are expensive, require enhanced biosecurity, compromise welfare, and are frequently influenced by confounding variables. Since the chicken embryo becomes immunocompetent prior to hatch, we here characterized the transcriptional response of selected innate immune genes to Newcastle disease virus (NDV) infection in chicken embryos at days 10, 14, and 18 of embryonic development. The results suggest that the innate immune response 72 h after challenge of 18-day chicken embryo is both consistent and robust...
