Atrazine (ATR) is one of the most extensively used herbicide that eventually leaches into groundwater and surface water from agricultural areas. Exposure to ATR does harm to the health of human and animals, especially the heart. However, ATR exposure caused cardiotoxicity in bird remains unclear. To evaluate ATR-exerted potential cardiotoxicity in heart, quail were exposed with 0, 50, 250, and 500 mg/kg BW/day ATR by gavage treatment for 45 days. Cardiac histopathological alternation was observed in ATR-induced quail...

Role of estrogen and photoperiod is well-established in avian reproduction. In addition, the distribution and the expression of arginine vasotocin (AVT) and its receptor VT3 to ensure reproductive/breeding conditions in Japanese quail influenced by them has been the main focus of this review. To consider this aspect the mRNA expression of VT3 receptor and its ligand AVT in the shell gland has been emphasized. In birds, AVT performs a dual role as an anti-diuretic hormone and the functions accomplished by oxytocin in mammals...

The emergence of Middle East respiratory syndrome showed once again that coronaviruses (CoVs) in animals are potential source for epidemics in humans. To explore the diversity of deltacoronaviruses in animals in the Middle East, we tested fecal samples from 1,356 mammals and birds in Dubai. Four novel deltacoronaviruses were detected from eight birds of four species by RT-PCR: FalCoV UAE-HKU27 from a falcon, HouCoV UAE-HKU28 from a houbara bustard, PiCoV UAE-HKU29 from a pigeon and QuaCoV UAE-HKU30 from five quails...

The aim of this study was to investigate the role of heat shock protein 70 (Hsp70) in oxidative stress and inflammatory damage in the spleen of quails which were induced by cold stress. One hundred ninety-two 15-day-old male quails were randomly divided into 12 groups and kept at 12 ± 1 °C to examine acute and chronic cold stress. We first detected the changes in activities of antioxidant enzymes in the spleen tissue under acute and chronic cold stress. The activities of glutathione peroxidase (GSH-Px) fluctuated in acute cold stress groups, while they were significantly decreased (p < 0...

Background: Japanese quail (Coturnix japonica), a recently domesticated poultry species, is important not only as an agricultural product, but also as a model bird species for genetic research. However, most of the biological questions concerning genomics, phylogenetics and genetics of some important economic traits have not been answered. It is thus necessary to complete a high-quality genome sequence as well as a series of comparative genomics, evolution and functional studies. Results: Here, we present a quail genome assembly spanning 1...

How does form arise during development and change during evolution? How does form relate to function, and what enables embryonic structures to presage their later use in adults? To address these questions, we leverage the distinct functional morphology of the jaw in duck, chick, and quail. In connection with their specialized mode of feeding, duck develop a secondary cartilage at the tendon insertion of their jaw adductor muscle on the mandible. An equivalent cartilage is absent in chick and quail. We hypothesize that species-specific jaw architecture and mechanical forces promote secondary cartilage in duck through the differential regulation of FGF and TGFβ signaling...

Quail meat is an emerging source of high-quality animal protein. Quails are exposed to a wide range of xenobiotics such as heavy metals. In this study, residual concentrations of four toxic metals, of significant public health importance, including cadmium (Cd), lead (Pb), arsenic (As), and nickel (Ni), were determined in edible tissues of quails. In addition, metal loads were measured in water, feed, and litter samples collected from same quail farms as possible sources for quail exposure to heavy metals. The possible use of metallothionein (MT) and heat shock protein 70 (Hsp70) as molecular biomarkers of exposure to heavy metals was further investigated...

BACKGROUND: Most trials regarding catheter-based renal sympathetic denervation (RDN) describe a proportion of patients without blood pressure response. Recently, we were able to show arterial stiffness, measured by invasive pulse wave velocity (IPWV), seems to be an excellent predictor for blood pressure response. However, given the invasiveness, IPWV is less suitable as a selection criterion for patients undergoing RDN. Consequently, we aimed to investigate the value of cardiac magnetic resonance (CMR) based measures of arterial stiffness in predicting the outcome of RDN compared to IPWV as reference...

A captive-bred Bobwhite Quail ( Colinus virginianus) ranch in southern Utah experienced high mortality rates in the late summer and fall of 2012. Nine juvenile birds were necropsied at the Utah Veterinary Diagnostic Laboratory. Gross lesions included pale skeletal muscle with multifocal hemorrhages and petechiae in the air sacs and serosal surfaces of most organs. Histologically there was moderate to severe, multifocal, degenerative myositis with intramyofiber schizonts and minimal lymphoplasmacytic infiltrates in the proventriculus, ventriculus, heart, and skeletal muscle...

Samples from 45 chickens, two turkeys, one peacock and one quail with symptoms of fowlpox were collected in Mozambique between November 2016 and January 2018. Phylogenetic analysis revealed that the samples contained avipoxviruses belonging to both clade A1 and clade A2. In addition, all of the Clade A1 viruses were positive by PCR for the integration of reticuloendotheliosis virus, while the clade A2 avipoxvirus samples were negative. This study confirms the circulation of clade A1 avipoxviruses in Mozambique in addition to identifying clade A2 for the first time in the country...

Aldose reductase (AR) is a rate-limiting enzyme in the polyol pathway and is also the key enzyme involved in diabetic complications. The silkworm purple quail-like mutant (q-lp ) exhibits pigmented dots on its epidermis. The q-lp mutant also shows developmental abnormalities and decreased vitality. In this study, fat bodies from the q-lp mutant and the wildtype 932VR strain were subjected to two-dimensional gel electrophoresis (2-DE) analysis, and the Bombyx mori AR (BmAR) protein was found to be significantly downregulated in the q-lp mutant...

This study investigated the relationship between sperm kinematics and egg fertility in Japanese quail in an attempt to identify a semen trait that could be used to predict male fertility. Males (n=45) and females (n=180) from five strains (A, B, C, D, E) were used. Ejaculates (n=720) were collected from 8 to 38 weeks of male age. Semen volume and sperm concentration were recorded and sperm motility was analyzed using Sperm Class Analyzer (SCA® -CASA). At the time of ejaculate collection, males were allowed to mate with females in order to obtain egg fertility data: percent fertile eggs and the numbers of sperm (SpermOPVL ) and sperm-holes (HolesIPVL ) present on the egg perivitelline membranes...

Two methodological criticisms of our paper "Synchronizing biological cycles as key to survival under a scenario of global change: The Common quail (Coturnix coturnix) strategy" (Nadal et al., 2018) were proposed in the comment by Rodriguez-Teijeiro et al. (2018) regarding: 1) our estimates of the mean date of arrival, duration of stay and departure stages in the different regions studied; and 2) the analyses carried out to correlate the phenology of the species with changes in the climate variables...

The social environment of reproducing females can cause physiological changes, with consequences for reproductive investment and offspring development. These prenatal maternal effects are often found to be sex-specific and may have evolved as adaptations, maximizing fitness of male and female offspring for their future environment. Female hormone levels during reproduction are considered a potential mechanism regulating sex allocation in vertebrates: high maternal androgens have repeatedly been linked to increased investment in sons, whereas high glucocorticoid levels are usually related to increased investment in daughters...

Lighting is crucial in poultry rearing and the subjects with light intensity, source, and color having been addressed in numerous studies. Numerous studies with monochromatic light from light-emitting diode (LED) bulbs have been reported. In the current study, fertile Japanese quail eggs were exposed to a dark environment (Control) or monochromatic green (560 nm) and blue (480 nm) lighting throughout incubation. There were no significant differences in hatch weight, hatchability, total embryonic mortality, hatch time, growth performance, and slaughter-carcass traits in the study (P > 0...

Northern bobwhite quail (Colinus virginianus) are a highly sought-after game bird in the Rolling Plains of West Texas. Unfortunately, bobwhite populations in this area are subject to dramatic fluctuations and have been steadily decreasing over the past several decades. While many factors have been investigated as potential mechanisms of cyclic and declining bobwhite numbers, the effect of parasites on bobwhite populations has historically been undervalued. Between December 2017 and February 2018, we received 21 hunter-shot bobwhite from Garza and Mitchell counties in Texas and found peak caecal worm (Aulonocephalus pennula) and eyeworm (Oxyspirura petrowi) burdens averaging 599 and 44, respectively...
