Apolipoprotein A-I of hyperlipidemia atherosclerosis prone (LAP) quail: cDNA sequence and tissue expression. (1/926)

Apolipoprotein A-I (apo A-I) has an important role in the transport of cholesterol. This study describes the complete nucleotide and deduced amino acid sequence for apo A-I of LAP quail. A full length apo A-I cDNA clone for hyperlipidemia atherosclerosis prone (LAP) quail was isolated from a lambda gt10 liver cDNA library. The DNA sequence of LAP apo A-I cDNA was similar to that of normal Japanese quail. The deduced amino acid sequence of LAP apo A-I was hence identical to that of normal Japanese quail. LAP apo A-I mRNA is about 1.4 kilobases in length and expressed in a variety of tissues including small intestine, liver, lung, breast muscle, testis, and heart. Although the tissue distribution of apo A-I was similar between strains, LAP quail expressed more apo A-I mRNA than normal Japanese quail in all tissues examined. This tendency was pronounced with the small intestine. Although the concentration of serum apo A-I did not correlate with the tissue expression of mRNA, the observation may suggest that the increased apo A-I expression in LAP strain had some relevance to the susceptibility of this strain to the experimental atherosclerosis.  (+info)

Production of donor-derived offspring by transfer of primordial germ cells in Japanese quail. (2/926)

We transfused concentrated primordial germ cells (PGCs) of the black strain (D: homozygous for the autosomal incomplete dominant gene, D) of quail into the embryos of the wild-type plumage strain (WP: d+/d+) of quail. The recipient quail were raised until sexual maturity and a progeny test of the putative germline chimeras was performed to examine the donor gamete-derived offspring (D/d+). Thirty-one percent (36/115) of the transfused quail hatched and 21 (13 females and 8 males) of them reached maturity. Five females and 2 males were germline chimeras producing donor gamete-derived offspring. Transmission rates of the donor derived gametes in the chimeric females and males were 1.8-8.3% and 2.6-63.0%, respectively. Germline chimeric and the other putative chimeric males were also test-mated with females from the sex-linked imperfect albino strain (AL: d+/d+, al/W, where al indicates the sex-linked imperfect albino gene on the Z chromosome, and W indicates the W chromosome) for autosexing of W-bearing spermatozoa: No albino offspring were born.  (+info)

Protective effects of type I and type II interferons toward Rous sarcoma virus-induced tumors in chickens. (3/926)

Growth of tumors induced by Rous sarcoma virus (RSV) is controlled by alleles at the major histocompatibility complex locus in chickens, indicating that immunological host defense mechanisms play a major role. We show here that the resistance phenotype of CB regressor chickens can be partially reverted by treating the animals with a monoclonal antibody that neutralizes the major serotype of chicken type I interferon, ChIFN-alpha. Injection of recombinant ChIFN-alpha into susceptible CC progressor chickens resulted in a dose-dependent inhibition of RSV-induced tumor development. This treatment was not effective, however, in CC chickens challenged with a DNA construct expressing the v-src oncogene, suggesting that the beneficial effect of type I interferon in this system resulted from its intrinsic antiviral activity and probably not from indirect immunmodulatory effects. By contrast, recombinant chicken interferon-gamma strongly inhibited tumor growth when given to CC chickens that were challenged with the v-src oncogene, indicating that the two cytokines target different steps of tumor development.  (+info)

Quantitative changes in integrin and focal adhesion signaling regulate myoblast cell cycle withdrawal. (4/926)

We previously demonstrated contrasting roles for integrin alpha subunits and their cytoplasmic domains in controlling cell cycle withdrawal and the onset of terminal differentiation (Sastry, S., M. Lakonishok, D. Thomas, J. Muschler, and A.F. Horwitz. 1996. J. Cell Biol. 133:169-184). Ectopic expression of the integrin alpha5 or alpha6A subunit in primary quail myoblasts either decreases or enhances the probability of cell cycle withdrawal, respectively. In this study, we addressed the mechanisms by which changes in integrin alpha subunit ratios regulate this decision. Ectopic expression of truncated alpha5 or alpha6A indicate that the alpha5 cytoplasmic domain is permissive for the proliferative pathway whereas the COOH-terminal 11 amino acids of alpha6A cytoplasmic domain inhibit proliferation and promote differentiation. The alpha5 and alpha6A cytoplasmic domains do not appear to initiate these signals directly, but instead regulate beta1 signaling. Ectopically expressed IL2R-alpha5 or IL2R-alpha6A have no detectable effect on the myoblast phenotype. However, ectopic expression of the beta1A integrin subunit or IL2R-beta1A, autonomously inhibits differentiation and maintains a proliferative state. Perturbing alpha5 or alpha6A ratios also significantly affects activation of beta1 integrin signaling pathways. Ectopic alpha5 expression enhances expression and activation of paxillin as well as mitogen-activated protein (MAP) kinase with little effect on focal adhesion kinase (FAK). In contrast, ectopic alpha6A expression suppresses FAK and MAP kinase activation with a lesser effect on paxillin. Ectopic expression of wild-type and mutant forms of FAK, paxillin, and MAP/erk kinase (MEK) confirm these correlations. These data demonstrate that (a) proliferative signaling (i.e., inhibition of cell cycle withdrawal and the onset of terminal differentiation) occurs through the beta1A subunit and is modulated by the alpha subunit cytoplasmic domains; (b) perturbing alpha subunit ratios alters paxillin expression and phosphorylation and FAK and MAP kinase activation; (c) quantitative changes in the level of adhesive signaling through integrins and focal adhesion components regulate the decision of myoblasts to withdraw from the cell cycle, in part via MAP kinase.  (+info)

Myotube heterogeneity in developing chick craniofacial skeletal muscles. (5/926)

Avian skeletal muscles consist of myotubes that can be categorized according to contraction and fatigue properties, which are based largely on the types of myosins and metabolic enzymes present in the cells. Most mature muscles in the head are mixed, but they display a variety of ratios and distributions of fast and slow muscle cells. We examine the development of all head muscles in chick and quail embryos, using immunohistochemical assays that distinguish between fast and slow myosin heavy chain (MyHC) isoforms. Some muscles exhibit the mature spatial organization from the onset of primary myotube differentiation (e.g., jaw adductor complex). Many other muscles undergo substantial transformation during the transition from primary to secondary myogenesis, becoming mixed after having started as exclusively slow (e.g., oculorotatory, neck muscles) or fast (e.g., mandibular depressor) myotube populations. A few muscles are comprised exclusively of fast myotubes throughout their development and in the adult (e.g., the quail quadratus and pyramidalis muscles, chick stylohyoideus muscles). Most developing quail and chick head muscles exhibit identical fiber type composition; exceptions include the genioglossal (chick: initially slow, quail: mixed), quadratus and pyramidalis (chick: mixed, quail: fast), and stylohyoid (chick: fast, quail: mixed). The great diversity of spatial and temporal scenarios during myogenesis of head muscles exceeds that observed in the limbs and trunk, and these observations, coupled with the results of precursor mapping studies, make it unlikely that a lineage based model, in which individual myoblasts are restricted to fast or slow fates, is in operation. More likely, spatiotemporal patterning of muscle fiber types is coupled with the interactions that direct the movements of muscle precursors and subsequent segregation of individual muscles from common myogenic condensations. In the head, most of these events are facilitated by connective tissue precursors derived from the neural crest. Whether these influences act upon uncommitted, or biased but not restricted, myogenic mesenchymal cells remains to be tested.  (+info)

Retinal TUNEL-positive cells and high glutamate levels in vitreous humor of mutant quail with a glaucoma-like disorder. (6/926)

PURPOSE: To investigate whether retinal cell death observed in an avian glaucoma-like disorder occurs by apoptosis and whether an increase in excitotoxic amino acid concentration in the vitreous humor is associated temporally with cell death in the retina. METHODS: Presumptive retinal apoptotic nuclei were identified by histochemical detection of DNA fragmentation (by TdT-dUTP terminal nick-end labeling [TUNEL]), and vitreal concentrations of glutamate and several other amino acids were determined by high-pressure liquid chromatography with fluorometric detection in the al mutant quail (Coturnix coturnix japonica) in which a glaucoma-like disorder develops spontaneously. RESULTS: TUNEL-labeled nuclei were located mostly in the ganglion cell layer (GCL) in the retina of mutant quails 3 months after hatching. However, labeled nuclei were also observed in the inner and outer nuclear layers. At 7 months, most TUNEL-positive nuclei were detected in the inner nuclear layer, whereas labeled cells in the GCL were reduced in number. No TUNEL-labeled nuclei were detected in the retina of control quails at any age. Vitreal concentrations of glutamate and aspartate were significantly increased in 1-month-old mutant quails compared with control animals. Concentrations decreased at 3 months, and no significant differences were observed between strains at 7 months. CONCLUSIONS: Presumptive apoptotic cell death is detected from 3 months after hatching in mutant quails and is not restricted to retinal ganglion cells. Cell death appears just after a significant increase in excitotoxic amino acid concentrations in the vitreous humor, suggesting a correlation between both events.  (+info)

Connexin 43 expression reflects neural crest patterns during cardiovascular development. (7/926)

We used transgenic mice in which the promoter sequence for connexin 43 linked to a lacZ reporter was expressed in neural crest but not myocardial cells to document the pattern of cardiac neural crest cells in the caudal pharyngeal arches and cardiac outflow tract. Expression of lacZ was strikingly similar to that of cardiac neural crest cells in quail-chick chimeras. By using this transgenic mouse line to compare cardiac neural crest involvement in cardiac outflow septation and aortic arch artery development in mouse and chick, we were able to note differences and similarities in their cardiovascular development. Similar to neural crest cells in the chick, lacZ-positive cells formed a sheath around the persisting aortic arch arteries, comprised the aorticopulmonary septation complex, were located at the site of final fusion of the conal cushions, and populated the cardiac ganglia. In quail-chick chimeras generated for this study, neural crest cells entered the outflow tract by two pathways, submyocardially and subendocardially. In the mouse only the subendocardial population of lacZ-positive cells could be seen as the cells entered the outflow tract. In addition lacZ-positive cells completely surrounded the aortic sac prior to septation, while in the chick, neural crest cells were scattered around the aortic sac with the bulk of cells distributed in the bridging portion of the aorticopulmonary septation complex. In the chick, submyocardial populations of neural crest cells assembled on opposite sides of the aortic sac and entered the conotruncal ridges. Even though the aortic sac in the mouse was initially surrounded by lacZ-positive cells, the two outflow vessels that resulted from its septation showed differential lacZ expression. The ascending aorta was invested by lacZ-positive cells while the pulmonary trunk was devoid of lacZ staining. In the chick, both of these vessels were invested by neural crest cells, but the cells arrived secondarily by displacement from the aortic arch arteries during vessel elongation. This may indicate a difference in derivation of the pulmonary trunk in the mouse or a difference in distribution of cardiac neural crest cells. An independent mouse neural crest marker is needed to confirm whether the differences are indeed due to species differences in cardiovascular and/or neural crest development. Nevertheless, with the differences noted, we believe that this mouse model faithfully represents the location of cardiac neural crest cells. The similarities in location of lacZ-expressing cells in the mouse to that of cardiac neural crest cells in the chick suggest that this mouse is a good model for studying mammalian cardiac neural crest and that the mammalian cardiac neural crest performs functions similar to those shown for chick.  (+info)

Neural crest can form cartilages normally derived from mesoderm during development of the avian head skeleton. (8/926)

The lateral wall of the avian braincase, which is indicative of the primitive amniote condition, is formed from mesoderm. In contrast, mammals have replaced this portion of their head skeleton with a nonhomologous bone of neural crest origin. Features that characterize the local developmental environment may have enabled a neural crest-derived skeletal element to be integrated into a mesodermal region of the braincase during the course of evolution. The lateral wall of the braincase lies along a boundary in the head that separates neural crest from mesoderm, and also, neural crest cells migrate through this region on their way to the first visceral arch. Differences in the availability of one skeletogenic population versus the other may determine the final composition of the lateral wall of the braincase. Using the quail-chick chimeric system, this investigation tests if populations of neural crest, when augmented and expanded within populations of mesoderm, will give rise to the lateral wall of the braincase. Results demonstrate that neural crest can produce cartilages that are morphologically indistinguishable from elements normally generated by mesoderm. These findings (1) indicate that neural crest can respond to the same cues that both promote skeletogenesis and enable proper patterning in mesoderm, (2) challenge hypotheses on the nature of the boundary between neural crest and mesoderm in the head, and (3) suggest that changes in the allocation of migrating cells could have enabled a neural crest-derived skeletal element to replace a mesodermal portion of the braincase during evolution.  (+info)

INTRODUCTION. Reproduction of birds depends on photoperiod, rainfall, humidity, temperature and food as well as intrinsic factors (Lake, 1981; Lofts & Murton, 1968). In temperate zones, seasonal day length variation serves as the primary role of timing reproductive periodicity (Lofts & Murton). The majority of species outside the tropics rely on a food resource for their young that become available for a predictable period each year. The length of the breeding season varies between species, but in the vast majority, the breeding season is asymmetrical with changes in photoperiod. When mature male coturnix were exposed to short photoperiods (6L: 18D) a rapid testicular weight reduction was recorded (Follett & Farner, 1966). Reduction of testicular weight in the common coturnix, exposed to short days (8 h of light), was more rapid in a colder than in a warmer environment (Wilson et al., 1971). The two most critical features in the seasonality of an environment are the amplitude of the seasonal ...

The present studyinvestigated the impact of selection for body weight (BW) on productive performance, predicted BW and genetic improvement of related traits in Japanese quail. Base population, selected parent and F1 progeny were tested. Pens and cages were used for rearing and breeding. A total of 240 birds in two successive generations, 27 sires and 54 dams (as selected parents) were used. Body weight from multiple regression equation, covariance analysis and combining models were estimated, response to selection, realized heritability and genetic correlation were computed for BW, weight gain (WG), feed intake (FI) and feed conversion ratio (FCR). The results showed that the response to selection for BW, WG, FI and FCR were 11.48 g, 27.04 g, 37 g and -0.2, respectively. The estimated heritabilities for the same traits were 0.78, 0.67, 0.52 and 0.77, respectively. Predicted equation (DUHOK equation) for BW as dependent variable on the initial body weight and sex ratio was derived. The final response for

In this work we have determined molecular signatures of oviduct epithelial and progenitor cells. We have proposed a panel of selected marker genes, which correspond with the phenotype of oviduct cells of a laying hen (Gallus gallus domesticus) and quail (Coturnix japonica). We demonstrated differences in characteristics of those cells, in tissue and in vitro, with respect to different anatomical and functional parts of the oviduct (infundibulum (INF), distal magnum (DM, and proximal magnum (PM)). The following gene expression signatures were studied: (1) oviduct markers (estrogen receptor 1, ovalbumin, and SPINK7 - ovomucoid), (2) epithelial markers (keratin 5, keratin 14, and occludin) and (3) stem-like/progenitor markers (CD44 glycoprotein, LGR5, Musashi-1, and sex determining region Y-box 9, Nanog homebox, OCT4/cPOUV gene encoding transcription factor POU5F3). In chicken, the expression of oviduct markers increased toward the proximal oviduct. Epithelial markers keratin14 and occludin were high in

The variability in toxic response of Japanese quail (Coturnix coturnix japonica) to a standardized 5-day subacute feeding trial was studied while age was increased at weekly intervals from 1 to 21 days and at different times with 14-day-old birds. The objectives were to identify the strengths and limitations of this subacute toxicity protocol and to provide possible explanations for differences in response among the various classes of pesticides. The variables included the median lethal concentration (LC50), the dose-response slope, food consumption, mortality patterns, and procedures of preparing toxic diets. Carbamate, organophosphate, chlorinated hydrocarbon, and organic mercury compounds were represented. A total of 60 subacute tests were involved in this evaluation. The general conclusions of the study are as follows: (1) The basic protocol yields good within-laboratory reproducibility of results. (2) The LC50s increase as birds grow older, and the change was reasonably predictable between 7 and 21

and heart rate between experimental and control groups in the current study do not manifest until the last third of incubation.. The secondary development period, or last few days of incubation, in reptiles and precocial birds is where organogenesis is complete and neuromuscular activity is increasing to prepare the neonate for complex movement immediately after hatching. This period has been proposed as the phase of incubation that can be shortened if necessary to reduce incubation period for group emergence from the nest. Japanese quail chicks (Coturnix coturnix japonica) with accelerated development take 1-2 h more to stand than normal chicks [20], and neuromuscular function of less-developed embryonic painted turtles (C. picta) is reduced for up to 9 months after hatching [14]. However, increases in metabolic rate in E. macquarii translated directly into increased rates of embryonic development because (i) more yolk reserves were used by experimental groups and (ii) neuromuscular ...
In our recent studies domesticated fowl species in the range from 150 g (Japanese quail, Coturnix coturnix japonica) to 19 kg (turkey, Meleagris gallopavo) were analysed, to elucidate supposed allometric relationship of the membrane lipid fatty acids (FA). The basis of all studies was the „membranes as pacemakers of metabolism" by Hulbert (Lipids, 2007, 42, 811-819). First in the myocardium (B=-0.6), later in the avian kidney (-0.18) and lung (-0.24), as well as liver (-0.2) negative allometric scaling was found for docosahexaenoic acid (DHA). In the membrane FAs of all these tissues rather balanced polyunsaturation, negatively scaling n3 and unsaturation index and oppositely related n6 and monounsaturated FA molar proportions were described. In the lavaged avian lung surfactant phopsholipids we reported similar negative allometry for DHA. In contarst, avian brain phospholipid FA composition failed to provide body mass relation. We found unexpected results (positive allometry for n3 FAs, DHA, ...
Diphasic Analysis of Growth in Japanese Quail Japanese Quail;Growth Curves;Monophasic Function;Diphasic Function;Asymptotic Weight;Growth Rate; A line of Japanese quail selected for increased body weight for 15 generations (C) and an unselected control line (K) were used to examine the impact of selection for body weight on the growth curve of Japanese quail. In addition, the effect of sex on the growth curve in each line was also studied, namely females of C (CF), males of C (CM), females of K (KF) and males of K (KM). The monophasic and diphasic growth models were studied for adequacy in describing growth curves of quail in both sexes of the C and K lines. The monophasic function provided almost the same growth rate for both sexes in both lines. However, the growth rates calculated by means of the diphasic function differed between sexes for both lines, except for those calculated for C during the second growth phase. While there were 2-3 days difference between sexes in age at maximum gain in both

Quail show social behaviors close to those observed in the chicken. Moreover, Japanese Quail and chickens have the same number of chromosomes despite showing several morphological differences [39]. As such, the Japanese Quail can be considered as a reliable model for the chicken in the field of genetics [40]. However, a previous study by Inoue-Murayama et al. [41] showed that genetic markers used in the genetic mapping for the chicken were ineffective in Japanese Quail, which highlighted the need to develop quail-specific markers. Consequently several maps were developed using AFLP markers [18], microsatellite markers [19] and both [20]. Comparisons between the information from the quail genetic map and from the assembled chicken sequence showed that the macrochromosomes of the two species had a highly conserved synteny [42]. Similarly, cytogenetic comparisons by Shibusawa et al. [43], showed conservation of the chromosomal organization between the two species. Nevertheless, Kayang et al. [42] ...
Japanese quail are hardy birds that thrive in small cages and are inexpensive to keep. They are affected by common poultry diseases but are fairly disease resistant. Japanese quail mature in about 6 weeks and are usually in full egg production by 50 days of age. With proper care, hens should lay 200 eggs in their first year of lay. Life expectancy is only 2 to 2½ years.. This illustrated Primefact includes information on breeding Japanese quail, incubation and hatching of eggs, brooding and care of young birds, housing, nutritional requirements, husbandry, disease prevention and control, and commercial processing and marketing.. ...

Vertebrates release glucocorticoids during stressful events. If stress occurs during reproduction, the resulting offspring can show altered phenotypes that are thought to arise from increased exposure to maternal glucocorticoids. Developing offspring can metabolize maternal glucocorticoids, which can alter the pattern of exposure they encounter. For egg laying vertebrates, we are just beginning to understand how embryonic steroid metabolism impacts embryonic exposure to maternal glucocorticoids. Here we injected three doses of radioactive corticosterone into Japanese quail (Coturnix japonica) eggs to determine the degree of embryonic exposure at days six and nine of development. We found that increasing injection dose increased the amount of radioactivity found in the embryo at day six but by day nine the effect of injection dose disappeared as the amount of radioactivity within the embryo dropped to equivalent levels for all three doses. Interestingly, when examined as a percentage of initial dose,

[more ▼]. A series of 4 experiments was designed to study the relationships between the activity of the aromatase (AA) in the preoptic area (POA) and the activation by testosterone (T) of copulatory behavior in gonadectomized male and female Japanese quail. The induction of AA by T in the POA is dose- and time-dependent. Levels of AA seen in sexually mature males are restored in castrated birds by a treatment with 20 to 40 mm silastic T capsules which produce physiological levels of steroid in the plasma. The minimal dose of T (10 mm implant) which reliably restores copulatory behavior approximately doubles the AA in the POA. The induction of AA is significantly larger in males than in females. A significant increase in AA is observed within 16 ...

In vivo administration of estradiol benzoate (E2B) or parathyroid hormone (PTH) stimulates in vitro renal conversion of 25-hydroxyvitamin D3 [25-(OH)D3] to 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3] in birds. In the present investigation, the effect of PTH on 1,25-(OH)2D3 production was studied in female Japanese quail pretreated with the antiestrogen, tamoxifen citrate (30 mg/kg) daily for 7 days. PTH was injected at two different doses (92 and 275 U.S.P. units/kg) every 8 hours during the last two days of tamoxifen treatment. E2B (0.1 and 1.0 mg/kg) was injected 24 hours before sacrifice. Control groups received vehicle only. All injections were given intramuscularly. Kidney homogenates were prepared and incubated with tritiated 25-(OH)D3. E2B-induced stimulation of 1,25-(OH)2D3 production was completely blocked by prior treatment with tamoxifen, but PTH-induced stimulation of 1,25-(OH)2D3 production was unaffected by antiestrogen treatment. When PTH and E2B were injected together, no additive ...

en] In Japanese quail, testosterone (T) increases the Nissl staining density in the medial preoptic nucleus (POM) in relation to the differential activation by T of copulatory behavior. The effect of T on protein synthesis was quantified here in 97 discrete brain regions by the in vivo autoradio-graphic C-14-leucine (Leu) incorporation method in adult gonadectomized male and female quail that had been treated for 4 weeks with T or left without hormone. T activated male sexual behaviors in males but not females. Overall Leu incorporation was increased by T in five brain regions, many of which contain sex steroid receptors such as the POM, archistriatum and lateral hypothalamus. T decreased Leu incorporation in the medial septum. Leu incorporation was higher in males than females in two nuclei but higher in females in three nuclei including the hypothalamic ventromedial nucleus. Significant interactions between effects of T and sex were seen in 13 nuclei: in most nuclei (n=12), T increased Leu ...
Coturnism is an illness featuring muscle tenderness and rhabdomyolysis (muscle cell breakdown) after consuming quail (usually common quail, Coturnix coturnix, from which the name derives) that have fed on poisonous plants. From case histories it is known that the toxin is stable as four-month-old pickled quail have been poisonous. Humans vary in their susceptibility; only one in four people who consumed quail soup containing the toxin fell ill. The toxin is apparently fat-soluble as potatoes fried in quail fat have proved poisonous. Coniine from hemlock consumed by quail has been suggested as the cause, though quail resist eating hemlock. Hellebore has also been suggested as the source of the toxin. It has also been asserted that this evidence points to the seeds of the annual woundwort (Stachys annua) being the causal agent. It has been suggested that Galeopsis ladanum seeds are not responsible. Migration routes and season may affect quail risk. Quail are never poisonous outside the migration ...
Abstract: In humans and other animals, melatonin is involved in the control of circadian biological rhythms. Here, we show that melatonin affects the temporal pattern of behavioral sequences in a noncircadian manner. The zebra finch (Taeniopygia guttata) song and the crow of the Japanese quail (Coturnix japonica) are courtship vocalizations composed of a stereotyped sequence of syllables. The zebra finch song is learned from conspecifics during infancy, whereas the Japanese quail crow develops normally without auditory input. We recorded and analyzed the complete vocal activity of adult birds of both species kept in social isolation for several weeks. In both species, we observed a shortening of signal duration following the transfer from a light-dark (LD) cycle to constant light (LL), a condition known to abolish melatonin production and to disrupt circadian rhythmicity. This effect was reversible because signal duration increased when the photoperiod was returned to the previous LD schedule. ...
There can be no doubt that the Hebrew word in the Pentateuch (Exodus 16:13; Numbers 11:31,32) and in the 105th Psalm, denotes the common quail, Coturnix dactylisonans . (The enormous quantity of quails taken by the Israelites has its parallel in modern times. Pliny states that they sometimes alight on vessels in the Mediterranean and sink them. Colenel Sykes states that 160,000 quails have been netted in one season on the island of Capri.--ED.) The expression "as it were two cubits (high) upon the face of the earth," (Numbers 11:31) refers probably to the height at which the quails flew above the ground, in their exhausted condition from their long flight. As to the enormous quantities which the least-successful Israelite is said to have taken viz. "ten homers" (i.e. eighty bushels) in the space of a night and two days, there is every reason for believing that the "homers here spoken of do not denote strictly the measure of that name but simply "a heap." The Israelites would have had little ...
Everyone has heard of chicken eggs as they are the most popular types of eggs consumed. But did you know that quail eggs, which taste pretty similar to chicken eggs though they are a little stronger, due to a higher yolk-to-white ratio, have a much higher nutritional value than its counterpart? Thats right! Quail eggs have an abundance of health benefits, and, with regular consumption, will help combat a number of illnesses and diseases. Quail eggs are smaller in size than chicken eggs but they are packed with tons of nutrients and have more than double the nutritional value than chicken eggs. They dont contain any bad cholesterol, known as LDL, only the good kind of cholesterol, called HDL.. If you consume quail eggs regularly, you will get a boost in energy, thanks to the amount of antioxidants, minerals and protein they contain.

Neural crest cells (NCCs) are a multipotent, migratory cell population that generates an astonishingly diverse array of cell types during vertebrate development. The trunk neural crest has long been considered of particular significance. First, it has been held that the trunk neural crest has a morphogenetic role, acting to coordinate the development of the peripheral nervous system, secretory cells of the endocrine system and pigment cells of the skin. Second, the trunk neural crest additionally has skeletal potential. However, it has been demonstrated that a key role of the trunk neural crest streams is to organize the innervation of the intestine. Although trunk NCCs have a limited capacity for self-renewal, sometimes they become neural-crest-derived tumor cells and reveal the fact that that NCCs and tumor cells share the same molecular machinery. In this review we describe the routes taken by trunk NCCs and consider the signals and cues that pattern these trajectories. We also discuss recent

The tiny, speckled eggs of Japanese quail should be easy targets for hungry predators. But these quail have a survival advantage - each goes out of her way, research suggests, to choose a nesting location that best matches the particular color pattern of her eggs.
The statistical analysis was performed using the General Linear Model function of the SPSS (2007) Ver. 16.0.1 statistical package (SPSS Inc., Chigaco, IL, USA). The experimentation was based on a factorial model 2 x 2 (MOS x acidifier) or 2 x 2 x 2 (MOS x acidifier x sex). The one-way analysis of variance for the four experimental groups was performed. Also, the two-way analysis of variance and three-way analysis of variance (when applicable) were performed, using as main effects the inclusion of MOS in the feed (two levels), the inclusion of CPr in the feed (two levels) and the sex of the birds (two levels, when applicable). A value of P ,0.050 was considered significant. The Levenes test was applied to test the homogeneity of the variances. Tukeys test was applied to determine statistical differences between the means.. Results and Discussion. The effect of sex and dietary supplementation of MOS and CPr on the body weight is presented in Table 2. During the six weeks of the experimentation ...

Once upon a time, this was a quail hunters Avalon. Now all thats left of those splendid days are the reveries of old men.. Many of those hunters are too afflicted by the ravages of time to hunt anymore, and some are dead. The few who are still fit say it makes no sense to traipse across those russet and sable fields and draws anymore, because our quail are no more.. How glorious were those days of old? Compared to today, beyond belief.. For instance, Arkie Covert of McLouth remembers how he and the late Bruce Tate of Lawrence and their pointers used to hunt a farmstead near Clinton in the 1960s.. By noon they would flush 10 big coveys, and Covert said: "There were so dang many coveys that we never bothered hunting and shooting the single birds.".

Youll normally see California Quail walking, running, or scratching at the ground and leaf litter for seeds and other food. They occasionally forage in trees. California Quail generally forage in open areas but stay close to cover. When running, they can move amazingly quickly despite their short legs. If pressed by a predator they will burst into flight with rapid, whirring wingbeats. California Quail form flocks known as coveys in fall and winter; these usually contain family groups and can number more than 75 individuals. They roost in trees and feed mainly in the morning and evening, spending most of the day in shrubs that shade them from the sun and protect them from predators. ...

The attached patch fixes the quail Inscript (Indian language family) input methods when the underlying keyboard layout is not qwerty. The inscript layout is positional---the vowels should be under the left hand. quail-keyboard-layout should be consulted to ensure this happens. Each of the inscript layouts is defined by calling quail-define-inscript-package, so one change should fix them all.

An experiment was conducted to evaluate the additional effects of two ground medicinal herbs oat bran (OB) and dill seed (DS) on serum lipids, carcass characteristics and growth performance in Japanese quails. A total of 240-twenty one day of age male Japanese quails were allocated randomly to 3 treatments with 4 replicates of 20 birds per cage. Birds during the 22-49 days on trial received 3 dietary treatments: 1) control diet, 2) diets with 3% OB and 3) diets with 3% DS. From 4-7 weeks of age, body weight gain was higher for OB-fed birds (P|0.05) compared to other treatments, while the body weight gain of DS-fed birds was intermediate (P|0.05). Birds that received diet containing DS consumed significantly (P|0.05) lower feed compared to two other groups. Over the experimental periodfeed conversion ratio (FCR) was significantly improved in the group that received 3% DS compared to other treatments (P|0.05). Carcass weight and carcass components was not positively influenced by the dietary treatments (P
Results of recent studies showed that 2,3,4,7,8-pentachlorodibenzofuran (PeCDF) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) are equipotent in domestic chicken (Gallus gallus domesticus) while PeCDF is more potent than TCDD in ring-necked pheasant (Phasianus colchicus) and Japanese quail (Coturnix japonica). To elucidate the mechanism(s) underlying these differences in relative potency of PeCDF among avian species, we tested the hypothesis that this is due to species-specific differential binding affinity of PeCDF to the aryl hydrocarbon receptor 1 (AHR1). Here, we modified a cell-based binding assay that allowed us to measure the binding affinity of dioxin-like compounds (DLCs) to avian AHR1 expressed in COS-7 (fibroblast-like cells). The results of the binding assay show that PeCDF and TCDD bind with equal affinity to chicken AHR1, but PeCDF binds with greater affinity than TCDD to pheasant (3-fold) and Japanese quail (5-fold) AHR1. The current report introduces a COS-7 whole-cell binding ...
A 2 × 2 × 3 factorial arrangement of treatments was used to investigate the effects of two levels of dietary crude protein (200 or 240 g kg-1) and two inclusion rates of phytase enzyme supplementation (with or without) on performance, jejunum morphology, and some hematological parameters of Japanese quails fed diets based on three graded levels of sesame (Sesamum indicum) meal (0, 120, and 240 g kg-1 of the diet). A total of 480 Japanese quail chicks were randomly allocated to 12 treatments with 4 replicates of 10 Japanese quails. The results showed that feed intake was decreased in quails fed diets containing 240 g kg-1 of sesame meal (P , 0.05). Diets with 120 and 240 g kg-1 inclusion rates of sesame meal improved feed conversion ratio (FCR) in Japanese quail (P , 0.05). Results indicated that the higher level of crude protein improved protein efficiency ratio (PER) and increased feed intake (P , 0.05). The results of jejunum morphology showed that diets containing 120 and 240 g kg-1 sesame ...
1OVO: Crystallographic refinement of Japanese quail ovomucoid, a Kazal-type inhibitor, and model building studies of complexes with serine proteases.
A technique appropriate to investigation of the developmental fates of distinct embryonic cell types is described and the fate of a particular type of chick myoblast (CMR-I) examined. CMR-I myoblast clones are morphologically different from other chick myoblast clone types and can readily be identified in living cultures.. After two weeks of culture CMR-I myoblast clones were collected, aggregated, and transplanted into the prospective dorsal thigh region of young quail embryos. After four days of growth, cells of the transplant-containing quail legs were grown as clones. Chick clones were located by Feulgen staining and identified as muscle or non-muscle and, if muscle, as CMR-I or not; 91% of the chick clones recovered from transplants were muscle clones, and of these 97% were CMR-I. It was concluded that CMR-I myoblasts do not undergo a change in differentiated state identifiable by clonal analysis.. Other transplant-containing quail legs were fixed, sectioned, and Feulgen stained. The ...
Massachusetts General Hospital and Harvard Medical School Purpose: Vertebrate neural crest development depends on pluripotent, migratory neural crest (NC) cells. Isolation and culture of zebrafish NC cells has not been previously reported. In vitro culture of NC cells allows evaluation of in vivo findings in a more controlled environment. Here we report for the first time the isolation, in vitro culture and characterization of NC cells from zebrafish embryos. We apply the NC culture to determine if these cells possess stem cell or progenitor cell properties of multi-lineage differentiation, maintenance and renewal.. Methods: NC cells were isolated from transgenic sox10::egfp embryos using FACS and cultured in a complex proliferation medium, on substrates coated with extra cellular matrix proteins, with growth factors to induce differentiation into various lineages. NC multi-lineage differentiation was determined by immunocytochemistry and RT-PCR, cell migration was assessed by wound healing ...
I work as a research associate studying avian reproduction. We are currently working on a model system to aid in preserving endangered birds by transferring gonadal stem cells (self-renewing cells that are located in the gonads and produce sperm or eggs) into chicken embryos. The cells that I inject, or transfer, are adult gonadal stem cells collected from male quails. I inject quail cells to develop the method, because it is easier to get quail testes than testes from exotic birds.. Let me give you a little background in the development of birds as it relates to our project. Their gonadal stem cells circulate throughout the bloodstream before they migrate to the gonad, where they mature and produce either sperm or eggs. Because we inject the adult male quail gonadal stem cells into early stage chicken embryos, they will also migrate to the gonadal ridge. When this rooster reaches maturity, he will produce both chicken sperm and quail sperm derived from the injected cells. The goal is to be able ...
Neural crest cells were transplanted from one position in the body to another position. They developed into neural crest derivates from their new position. Neural crest cells are apparently pluripotent, as they give rise to the cell types expected from the position to which they have been transplanted.. For example, any neural crest cell can give rise to parasympathetic ganglia if transplanted to a certain position. Thus, neural crest cells must respond to environmental cues during their migration and subsequent differentiation. These environmental cues are often identical to the cues used by axons. ...
The neural crest is an embryonic cell population that gives rise to much of the vertebrate craniofacial skeleton, and its evolutionary origin is generally regarded as a key step in the diversification of vertebrates. Neural crest fate maps have been generated for a number of osteichthyan model systems (e.g. mouse, chick, frog and zebrafish). However, nothing is known about the fates of neural crest cells in chondrichthyans. We have developed methods for long-term lineage tracing of cell populations in early skate embryos, and we are using these methods to generate fate maps of chondrichthyan cranial and trunk neural crest cells. This work will allow us to infer primitive fates of neural crest cells in the last common ancestor of jawed vertebrates (e.g. neural crest vs. mesodermal contributions to the craniofacial skeleton and pectoral girdle, and the skeletogenic potential of trunk neural crest cells), thereby resolving a number of outstanding controversies relating to the early evolution of the ...
I also have quail and chickens, and it is the same setup as most replies here. I let my chickens run during the day, whereas my quail are penned 24/7. They are always kept separate for several reasons. The most important would be the disease factor, where chickens could bring a virus, etc. into your quail population. Secondly important would be the fact that the chickens are pretty carefree when it comes to being around other animals and humans, where the quail are very high strung, flighty, and not too inviting to outsiders. Having this combination together would put a great deal of stress on your quail, which would in turn hinder egg production, feeding, etc. I can tell you that my quail have finally gotten used to the chickens coming around their pen to clean up the loose waste feed underneath(one benefit). So, I would say raise them separately, and avoid housing both together as best as you can. Replacing a few chickens wouldnt be near as costly as your quail. Navigation. [0] Message ...
Step 1: Preheat the oven to 220C fan-forced (240C conventional). Place the grape leaves (if using) on a baking tray and set aside.. Step 2: Place half the figs in a bowl, then drizzle with a little olive oil and add the lemon thyme and lemon zest. Stuff each quail cavity evenly with this mixture. Tuck the wings of each quail behind the bird. Rub the quail skin with a little olive oil and season with salt and pepper.. Step 3: Melt the butter in a heavy-based frying pan over high heat and cook for 2-3 minutes until nut brown, adding the olive oil when the butter starts to bubble to prevent it from burning. Reduce the heat to low-medium, then very gently seal the quail on all sides for 8 minutes, turning until just light-golden all over. Place the quail, breast side up, on top of the grape leaves (if using) on the baking ray, then put a slice of bacon over each quail breast and place the remaining figs on the tray.. Step 4: Roast the quails for 6-8 minutes or until just cooked. To test if the ...
Because of its unique ability to generate a wide variety of both neural and nonneural derivatives, the neural crest is an ideal model system to study the factors regulating cell lineage decisions in stem and progenitor cells. The use of various cell culture techniques and in vivo functional assays, including cell type-specific gene manipulation in mouse, helped to identify signaling factors involved in this process. Moreover, it became apparent that the biological functions of growth factors acting on neural crest cells depend on the context provided by the extracellular microenvironment. Thus, signaling molecules have to be viewed as parts of complex networks that change with time and location. Neural crest cells have to integrate these signals to ensure the generation of appropriate numbers of differentiating progeny. It will be important to determine how such signaling networks are established and how they elicit multiple signaling responses in neural crest cells to activate appropriate ...
The first objective of this thesis was to investigate effects of endocrine disruptors on the developing brain and gonads of bird embryos. The substances studied were the insecticide methoxychlor, and nine UV-filters (3-benzylidene camphor (3BC), 4 methyl benzylidene camphor (4MBC), benzophenone (BP) 1,2 and 3, 4 hydroxy benzophenone (4 HB), 4 dihydroxy benzophenone (4DHB), benzyl salicylate (BS), and ethyl-4-aminobenzoate Et-PABA)), commonly used in cosmetic products. Some of these substances have no estrogenic effect in vitro, but have been shown to be estrogenic in vivo. The PCB-mixture Clophen A50 is a well-known inducer of biotransformation enzymes and was co-administered with methoxychlor and the UV-filters 3BC and 4MBC.. Exposure to 3BC or 4MBC caused ovotestis formation and malformations of the Müllerian ducts in Japanese quail embryos. Co-exposure to one of these compounds and Clophen A50 enhanced the effects, indicating that Clophen A50 potentiates the effects of the UV-filters. ...
The effect of fenitrothion exposure on birds was examined by measuring aerobic metabolism, blood hemoglobin content, plasma cholinesterases, and body weight for up to 21 d postdose. Peak metabolic rate was measured in a flight chamber in three-dose groups of house sparrows (Passer domesticus; 100 mg/kg = high, 60 mg/kg = medium, 30 mg/kg = low) and one-dose groups of zebra finches (Taeniopygia guttata; 3 mg/kg) and king quails (Coturnix chinensis; 26 mg/kg). Aerobic metabolism was measured during 1 h of exposure to subfreezing thermal conditions in low-dose house sparrows and king quails (26 mg/kg). Fenitrothion had no effect on metabolic rate during cold exposure or on blood hemoglobin at any time. By contrast, aerobic performance during exercise in sparrows was reduced by 58% (high), 18% (medium), and 20% (low), respectively, 2 d postdose. House sparrows (high) had the longest recovery period for peak metabolic rate (21 d) and plasma cholinesterase activity (14 d). House sparrows (high) and treated
Soybean oil (SBO), menhaden fish oil (FO), chicken fat (CF) or hydrogenated soybean oil (HSBO) were incorporated at 5% of the total diet to study changes in the immunological status of both Japanese quail (JAP) and Bobwhite quail (BOB). The SBO diet, in which 66% of the total fatty acids were polyunsaturated fatty acids (PUFA), was rich in linoleic acid (LA 18:2 n-6), alpha-linolenic acid (ALA 18:3 n-3) and low in saturated fatty acid (SFA). The FO diet which contained about 50% PUFA, had only 40% n-6 fatty acids and 8% n-3 PUFA. The trans fatty acid isomers and other monounsaturated fatty acids (MUFA) were high in the HSBO diet. The diet containing CF provided a relatively balanced fatty acid composition with 18% SFA, 31% MUFA and 50% PUFA. Plasma fatty acid and hepatic fatty acid profiles consistently reflected their respective dietary lipid treatments. There were no differences in the fatty acid profile between blood and liver within respective dietary treatments in the two species. Dietary ...
Within the hindbrain region, neural crest cell migration is organized into three streams that follow the segmentation of the neuroepithelium into distinct rhombomeric compartments. Although the streaming of neural crest cells is known to involve signals derived from the neuroepithelium, the molecular properties underlying this process are poorly understood. Here, we have mapped the expression of the signaling component of two secreted class III Semaphorins, Semaphorin (Sema) 3A and Sema 3F, at time points that correspond to neural crest cell migration within the hindbrain region of the chick. Both Semaphorins are expressed within rhombomeres at levels adjacent to crest-free mesenchyme and expression of the receptor components essential for Semaphorin activity by neural crest cells suggests a function in restricting neural crest cell migration. By using bead implantation and electroporation in ovo, we define a role for both Semaphorins in the maintenance of neural crest cell streams in proximity to the
This study assessed the presence of sialic acid α-2,3 and α-2,6 linked glycan receptors in seven avian species. The respiratory and intestinal tracts of the chicken, common quail, red-legged partridge, turkey, golden pheasant, ostrich, and mallard were tested by means of lectin histochemistry, using the lectins Maackia amurensis agglutinin II and Sambucus nigra agglutinin, which show affinity for α-2,3 and α-2,6 receptors, respectively. Additionally, the pattern of virus attachment (PVA) was evaluated with virus histochemistry, using an avian-origin H4N5 virus and a human-origin seasonal H1N1 virus. There was a great variation of receptor distribution among the tissues and avian species studied. Both α-2,3 and α-2,6 receptors were present in the respiratory and intestinal tracts of the chicken, common quail, red-legged partridge, turkey, and golden pheasant. In ostriches, the expression of the receptor was basically restricted to α-2,3 in both the respiratory and intestinal tracts and in mallards
Autoradiographic study of early stages of the anterior limb-bud in two species of chelonian embryos Embryos of two chelonian species (Testudo graeca L., Emys orbicularis L.) from 20-somites stage to 34-somites stage, fixed 2-4 h after an injection of tritiated thymidine or uridine or leucine, then emulsion-exposed 12-14 days, showed the following results:. (1) When the labelling index was determined in the mesoderm of the somatopleure, the labelling index in the flank region (S13-S16) remained at about 0·3 but the labelling index in the prospective anterior limb region rose to 0·4-0·5 when the processes of the somites S6-S13 reached the somatopleure. The somites seem to induce the proliferation of the somatopleure and the transformation of the somatopleural cells in mesoblastic basophilic cells.. (2) The dilated extremities of the processes of somites S6-S12 proliferate cells which become free from the somite and multiply. Thus, the somites S6-S12 participate materially in the constitution of ...
Austin, TX - The drought has taken a toll on all Texas wildlife resources, but among the hardest hit is the bobwhite quail. This iconic grassland game bird already faces mounting obstacles to recovery and state wildlife officials say the drought is exacerbating the problem.. "Weve been on point monitoring quail declines well before this current drought," said Clayton Wolf, Wildlife Director for the Texas Parks and Wildlife Department. "Weve been taking steps to address the problem, but the drought is raising the sense of urgency.". The Breeding Bird Survey (BBS), an annual field census survey used to track quail productivity, shows a decline in Texas bobwhite quail breeding numbers at a rate of 3.9 percent per year from 1970 to 2009. Texas bobwhite harvest has declined by 80 percent during the past three decades. Although this decline is not as steep as seen in southeastern states, it is still cause for concern.. Many reasons are cited for these declines, but evidence points to changes in the ...
