Full Text Available This study aimed at evaluating the use of scanning electron microscopy in the study of the post-vaccinal respiratory reaction of the tracheal epithelium of quails (Coturnix coturnix japonica immunized against Newcastle disease. A number of 36 quails were distributed into four groups: T1 fraction three-quarters control birds (non-vaccinated; T2 fraction three-quarters birds vaccinated with Ulster 2C strain; t3 fraction three-quarters birds vaccinated with B1 strain; t4 fraction three-quarters birds vaccinated with LaSota strain. Regardless the experimental group, birds did not show detectable clinical signs of post-vaccinal respiratory reaction. However, the analysis of tracheal fragments by scanning electron microscopy showed that birds vaccinated with B1 and LaSota strains developed epithelial sloughing of the trachea, whereas those vaccinated Ulster 2C strain did not develop this change, demonstrating intact tracheal epithelium, similar to the control group.

The impact of endocrine-disrupting chemicals (EDCs) has been demonstrated in mammalian models, but less research is available for avian species. The effects of vinclozolin (VIN), an antiandrogenic fungicide, on sexual differentiation and maturation were investigated in Japanese quail (Coturnix coturnix japonica). On day 4 of incubation, embryos were exposed to no treatment, oil, or 25, 50, or 100 ppm of VIN. Endpoints measured included adult male reproductive behavior, hypothalamic gonadotropin-releasing hormone I (GnRH-I) content in hatchlings and adults, plasma steroid levels in hatchlings and adults, proctodeal gland growth during maturation, and relative testicular weight at seven weeks of age. Results showed that exposure to VIN significantly (p < 0.05) altered GnRH-I in male hatchlings, whereas GnRH-I levels in females remained unaffected. Although steroid levels were unaltered by any VIN treatment, the display of male reproductive behavior seemed delayed, with the number of mounts and the number of cloacal contacts being significantly (p < 0.05) lower in the VIN-treated males. This could have an extreme negative impact on wild avian species that are routinely exposed to similar EDCs.

Full Text Available O estudo de corporações de uma das maiores economias mundiais se justifica em um mundo sem fronteiras no qual hoje vivemos e onde diferenças culturais afetam relações negociais. O objetivo é explicitar como as casas comerciais e outras corporações tradicionais japonesas conseguiram enorme longevidade. Foi privilegiado o papel desempenhado pelo kakun nessas corporações; ou seja, o papel desempenhado por um conjunto de preceitos e normas internas que, tendo surgido nos séculos XVII e XVIII, tem viva a sua força até os dias correntes. O método escolhido para o estudo foi a historiografia, que visa ao resgate dos acontecimentos e das atividades humanas ao longo do tempo. Chegamos à conclusão de que muito do que pregava o kakun está hoje presente em estudos sobre organizações e gestão e que, associado a questões éticas, o kakun é, em grande parte, o responsável pela longevidade das empresas japonesas.

The objective of this study was to evaluate the effect of feed supplement (FS) contained earthworm meal (EWM) on production performance of laying quails. Twenty weeks-old of 360 Coturnix coturnix japonica quails were used in a Completely Randomized Design (CRD) with three dietary treatments A = CD (control without FS), B = CD + 0.250 % of FS, and C = CD + 0.375 % of FS during 6 weeks of experimental period. Each treatment in 4 equal replicates in which 30 quails were randomly allocated into 12 units of cages. Variable measured were feed intake, feed conversion ratio, feed efficiency, mortality rate, hen day production, egg weight, and egg uniformity. Data were statistically analyzed by One Way ANOVA and the differences among mean treatments are analysed using Duncan’s Multiple Range Test (DMRT). The results showed that administration of 0.375% FS based on earthworm meal, fermented rice bran, and skim milk impaired the feed conversion ratio and increased the feed efficiency. The experimental treatments did not effect on feed intake, mortality, hen day production, egg weight, and egg uniformity of quail. It is concluded that administration of feed supplement improved the growth performance of quail.

An analysis of the mutability of developmental stages of male gametes of the japanese quail (Coturnix coturnix japonica), after irradiation with /sup 60/Co exposures (5.16; 15.48; and 30.96)x10/sup -2/C kg/sup -1/, i.e. 200, 600 and 1200 R, at an exposure rate of 8.59x10/sup -5/C kg/sup -1/s/sup -1/, i.e. O.33 R s/sup -1/, has shown that the rate of overall induced dominant lethality as well as the rate of mutation were highest in spermatocytes of the second order at all exposures. Starting from an exposure of 200 R the following values were found for lethal interference per 1 gamete for 1 R: spermatozoa 2.0x10/sup -3/, spermatides 1.95x10/sup -3/, spermatocytes II 6.1x10/sup -3/, spermatocytes I 4.06x10/sup -3/, spermatogonia in the process of differentiation 6.8x10/sup -3/. When analysing overall embryonic lethality, according to early and late lethality, dominant lethal mutations mainly manifested themsel--ves in the oviductal and germinal developmental periods, so that these periods can be considered as sensitive indices of genetic changes. The spermatogenic epithelium of the japanese quail was found to be greatly radioresistant since not even an exposure to 1200 R caused complete and permanent sterility.

Full Text Available ABSTRACT Often, in pet birds, any stimulus to lay eggs is unwanted in order to reduce reproductive diseases and disorders. The objectives of this study were: to determine the time necessary to promote ovary involution after an eight hour photoperiod using laying Japanese quails (Coturnix coturnix japonica; to connect the ovarian radiographic measurements with egg production; and to compare these measurements with direct ovary data obtained at necropsy. Birds were separated into three groups: 12h/24d (control group - 12h photoperiod for 24 days, 8h/24d and 8h/36d (8h photoperiod for 24 and 36 days. After euthanasia, all cadavers were x-rayed to measure ovary length and height. Birds were necropsied to measure ovarian length and weight. Results: radiographic ovary length demonstrated strong and positive correlation (r=0.96 with direct ovary length of all three groups; laying quails showed higher ovary height (p=0.025 and length (p=0.009 than non-laying quails; eight hours of artificial light per day promotes ovary length (p=0.025 and weight (p=0.009 reduction. Conclusions: radiography can estimate the ovary measure and indicate posture; an eight hour photoperiod of 24 days is not enough to promote ovarian regression, while the use of reduced photoperiod for 36 days promotes significant ovary involution.

The aim of the present study was to evaluate the effect of lighting programs for male and female meat quails raised in an equatorial region on performance and carcass traits. A total of 1,500 sexed quails (Coturnix coturnix) was distributed in a completely randomized design in a 2 × 3 factorial arrangement, with 2 sexes (male and female) and 3 lighting programs (natural, intermittent, and continuous) with 5 replicates of 50 birds. The lighting programs were applied in the period from 7 to 49 d of age, being natural (12 h and 30 min of natural light and 11 h and 30 min of dark), intermittent (12 h and 30 min of natural light and 5 h and 30 min of artificial light, alternating lighting periods with one h and 06 min and periods of darkness with one h and 12 min), and continuous (23 h of natural + artificial light and one h of dark). Regardless of lighting program, female quails were heavier than males, and birds subjected to natural light weighed less than those exposed to continuous and intermittent lighting programs. Quails exposed to intermittent and continuous light presented higher weight gain and feed intake, and worse feed conversion ratio compared to birds under a natural light regimen. It is concluded that in an equatorial region, it is possible to use a lighting program with only natural light for raising male and female meat quails from 7 to 49 d of age. © 2017 Poultry Science Association Inc.

Ludke, J.L.

1977-01-01

Adult male Japanese quail (Coturnix coturnix) were exposed to DDE or chlordane in the diet and subsequently dosed with parathion or paraoxon. Pretreatment with 5 or 50 ppm DDE in the diet for 12 weeks resulted in increased cholinesterase (ChE) activity in plasma, but not in the brain. Dietary concentrations of 5 and 50 ppm DDE caused increased susceptibility of quail that were challenged with parathion or paraoxon. The increased mortality resulting from DDE pretreatment was reflected in brain ChE inhibition. The synergistic action of DDE was apparent after 3 days of exposure to 50 ppm DDE and 1 week of exposure to 5 ppm DDE. Birds exposed for 3 weeks to 5 or 50 ppm DDE retained their DDE-potentiated sensitivity to parathion after 2 weeks on clean diet. Chlordane pretreatment resulted in decreased susceptibility (antagonism) to parathion, but not to paraoxon dosage. Implications of differing responses in ChE and mortality among controls, DDE-, and chlordane-pretreated birds after parathion or paraoxon dosage are discussed.

A population approach was used to evaluate the pharmacokinetic parameters of 3 fluoroquinolones administered to Japanese quail (Coturnix coturnix japonica). Healthy adult quail (n = 50) were divided into 3 groups, each administered a separate intravenous and oral dose of the compounded drug: enrofloxacin at 10 mg/kg (n = 18; 9 male, 9 female), danofloxacin at 10 mg/kg (n = 12; 6 male, 6 female), and marbofloxacin at 5 mg/kg (n = 20; 10 male, 10 female). A fourth group was used as a control (n = 5). Enrofloxacin was metabolized extensively to ciprofloxacin, while no metabolites of either danofloxacin or marbofloxacin were detected. The volume of distribution was high, greater than 1 in all cases, and highest for danofloxacin, followed by enrofloxacin, then marbofloxacin. The total body clearance was higher in quail than that reported for other avian species with the exception of ostriches. As in mammals, the lowest clearance rate of the 3 fluoroquinolones was observed for marbofloxacin. Enrofloxacin was absorbed most rapidly, followed by marbofloxacin, then danofloxacin. The highest bioavailability was observed for danofloxacin followed by marbofloxacin, while very low bioavailability with significant conversion to ciprofloxacin was observed for enrofloxacin. Population analysis showed low intersubject variability for danofloxacin and marbofloxacin in contrast to that for enrofloxacin and its main metabolite, ciprofloxacin. Because of their more favorable pharmacokinetic properties after oral administration, either danofloxacin or marbofloxacin appears to be preferable to enrofloxacin for the treatment of susceptible bacterial infection in Japanese quail.

This study was conducted in two separate experiments. Experiment I was conducted to investigate the effects of hemp seed (HS) on meat quality traits, and experiment II was designed to determine egg fatty acid (FA) composition in Japanese quail (Coturnix coturnix japonica). In experiment I and experiment II treatments, groups were as follows: (i) control (not included HS0), (ii) 5% HS inclusion to diets, (iii) 10% HS inclusion to diets and (iv) 20% HS inclusion to diets. In experiment I, a total of 192 7-day-old-quail were fed with HS diets for 5 weeks, and end of the experiment I, a total of 64 quail (16 each) slaughtered and meat samples were analysed for meat colour, pH, cooking and thawing loss and FA composition. In experiment II, a total of 120 8-week-old laying quail were fed with experimental diets for 6 weeks and egg FA composition were determined.

Detrended Fluctuation Analysis (DFA) is a method that has been frequently used to determine the presence of long-range correlations in human and animal behaviors. However, according to previous authors using statistical model systems, in order to correctly use DFA different aspects should be taken into account such as: (1) the establishment by hypothesis testing of the absence of short term correlation, (2) an accurate estimation of a straight line in the log-log plot of the fluctuation function, (3) the elimination of artificial crossovers in the fluctuation function, and (4) the length of the time series. Taking into consideration these factors, herein we evaluated the presence of long-range correlation in the temporal pattern of locomotor activity of Japanese quail (Coturnix coturnix) and mosquito larva (Culex quinquefasciatus). In our study, modeling the data with the general autoregressive integrated moving average (ARFIMA) model, we rejected the hypothesis of short-range correlations (d=0) in all cases. We also observed that DFA was able to distinguish between the artificial crossover observed in the temporal pattern of locomotion of Japanese quail and the crossovers in the correlation behavior observed in mosquito larvae locomotion. Although the test duration can slightly influence the parameter estimation, no qualitative differences were observed between different test durations.

Inorganic and organic mercury chloride toxicity to Coturnix: Sensitivity related to age and quantal assessment of physiologic responses

Hill, E.F.

1982-01-01

The toxicities of mercuric chloride (HgCl(,2)) and methylmercuric chloride (CH(,3)HgCl) were compared for coturnix (Coturnix coturnix japonica) from hatching to adulthood. Comparisons were based on: (1) Median lethal dosages (LD50) derived by administering single peroral and single intramuscular dosages of mercury, (2) median lethal concentrations (LC50) derived by feeding mercury for 5 days, (3) median toxic concentrations (TC50) derived by feeding mercury 9 weeks and measuring plasma enzyme activity, plasma electrolytes, and other blood constituents, and (4) transient changes of various blood chemistries following a single peroral dose of mercury. Acute peroral and intramuscular LD50s for HgCl(,2) and CH(,3)HgCl increased by two- to threefold for coturnix chicks from hatching to 4 weeks of age. Concomitantly, the LC50s also increased, but the important difference between test procedures was that with both single dose routes of exposure the toxicity ratios, i.e., HgCl(,2)/CH(,3)HgCl, at each age were about 2 to 2.5 compared to about 100 for the LC50s. For example, at 2 weeks of age the peroral LD50s for HgCl(,2) and CH(,3)HgCl were 42 and 18 mg/kg; the dietary LC50s were 5086 and 47 ppm for HgCl(,2) and CH(,3)HgCl. The 9 week feeding trial was not associated with gross effects from either HgCl(,2) at 0.5 to 32 ppm or CH(,3)HgCl at 0.125 to 8 ppm. However, subtle responses were detected for the plasma enzymes aspartate aminotransferase, lactate dehydrogenase, and ornithine carbamoyl transferase and could be quantified by probit analysis. This quantal procedure was based on establishment of a normal value for each enzyme and classing outliers as respondents. A 'hazard index' based on the TC50 for an enzyme divided by the LD50 or LC50 was introduced. The single oral dosages of HgCl(,2) and CH(,3)HgCl showed that ratios of alanine aminotransferase, lactate dehydrogenase, and orinthine carbamoyl transferase for the liver and kidneys of adult coturnix were opposite from

Full Text Available ABSTRACT This study was designed to find the effect of vitamin E supplementation on growth, serum antioxidant enzymes, and some trace elements in Japanese quail (Coturnix coturnix japonica under low ambient temperature. A total of 180 day-old Japanese quails were randomly divided into four groups and provided with 0 (group A, 50 (group B, 100 (group C, and 150 IU/kg (group D vitamin E (dl-α-tocopherol acetate under an average temperature of 9±0.5 °C for an experimental period of 42 days. The result showed that feed intake per day, body weight, weight gain per day, and feed conversion ratio did not differ significantly between the groups. Serum concentrations of superoxide and glutathione peroxidase were significantly high in birds supplemented with 150 mg/kg of vitamin E. The concentration of aspartate aminotransferase was not significantly affected between the control and treated groups; however, alanine transaminase concentration significantly reduced in group D. Zinc concentration in the blood increased significantly in group D, with no significant effect on copper and manganese between the control and treated groups. Vitamin E at the level of 150 IU/kg of feed improves the blood antioxidant status and zinc concentration, with no effect on the performance traits of quail reared under low ambient temperature.

Comprehensive Identification of Sexual Dimorphism-Associated Differentially Expressed Genes in Two-Way Factorial Designed RNA-Seq Data on Japanese Quail (Coturnix coturnix japonica.

Directory of Open Access Journals (Sweden)

Kelsey Caetano-Anolles

Full Text Available Japanese quail (Coturnix coturnix japonica reach sexual maturity earlier, breed rapidly and successfully, and cost less and require less space than other birds raised commercially. Given the value of this species for food production and experimental use, more studies are necessary to determine chromosomal regions and genes associated with gender and breed-differentiation. This study employed Trinity and edgeR for transcriptome analysis of next-generation RNA-seq data, which included 4 tissues obtained from 3 different breeding lines of Japanese quail (random bred control, heavy weight, low weight. Differentially expressed genes shared between female and male tissue contrast groups were analyzed to identify genes related to sexual dimorphism as well as potential novel candidate genes for molecular sexing. Several of the genes identified in the present study as significant sex-related genes have been previously found in avian gene expression analyses (NIPBL, UBAP2, and other genes found differentially expressed in this study and not previously associated with sex-related differences may be considered potential candidates for molecular sexing (TERA, MYP0, PPR17, CASQ2. Additionally, other genes likely associated with neuronal and brain development (CHKA, NYAP, as well as body development and size differentiation (ANKRD26, GRP87 in quail were identified. Expression of homeobox protein regulating genes (HXC4, ISL1 shared between our two sex-related contrast groups (Female Brain vs. Male Brain and Ovary vs. Testis indicates that these genes may regulate sex-specific anatomical development. Results reveal genetic features of the quail breed and could allow for more effective molecular sexing as well as selective breeding for traits important in commercial production.

To investigate the status, problems and prospects of Japanese quail (Coturnix coturnix japonica) farming in selected areas of Bangladesh. The study was conducted in 14 districts of Bangladesh, viz., Dhaka, Narayanganj, Munshiganj, Mymensingh, Netrakona, Faridpur, Jessore, Khulna, Satkhira, Kushtia, Bogra, Naogaon, Comilla, and Sylhet during the period from July 2011 to June 2012. A total of 52 quail farmers were interviewed for data collection using a structured questionnaire. Focus group discussions were also carried out with unsuccessful farmers and those want to start quail farming. Workers of quail farms, quail feeds and medicine suppliers, quail eggs and meat sellers were also interviewed regarding the issue. Out of 52 farms, 86.5% were operated by male, 67.3% farmers did not receive any training and 92.3% farmers had no earlier experience of quail farming although 58.0% farmers primary occupation was quail farming. Most of the farms (63.4%) were mixed in type having ≤5000 birds of two or three varieties. About 80.7% farms were operated separately round the year with no other poultry and 83.0% farmers wanted to expand their farming. The average pullet weight 145.0±0.12, 110.0±0.07, 120.0±0.22, and 128.0±0.17 g; age at the first lay 46.0±0.04, 42.0±0.31, 42.0±0.09, and 45.2±0.05 days; rearing period 15.0±0.01, 12.0±0.14, 15.0±0.32, and 15.2±0.18 months; culling period 15.5±0.14, 13.0±0.06, 15.0±0.03, and 15.4±0.26 months were for layer, parent stock, hatchery, and mixed farms, respectively. Most of the layer farms had an average egg production of ≤5000/day and net profit BDT 0.75/egg. However, an average number of birds, hatchability and net profit per day-old-chick were ≤5000, 76.8% and BDT 2.75, respectively, in the hatchery. Broiler quails were sold at 30 days with mean weight of 110.8 g and net profit BDT 9.02/bird. The major constraints of quail farming were higher feed price, outbreak of endemic diseases, lack of proper knowledge

Pairing Behavior of the Monogamous King Quail, Coturnix chinensis.

Directory of Open Access Journals (Sweden)

Elizabeth Adkins-Regan

Full Text Available Animals with socially monogamous mating systems are valuable for discovering proximate mechanisms of prosocial behavior and close social relationships. Especially powerful are comparisons between related species that differ in monogamous tendency. Birds are the most socially monogamous vertebrates. Thus far most research on mechanisms of pairing has used zebra finches, which do not have a relative with a different mating system, however. The goal of the experiments reported here was to develop a new comparative avian system by studying the pairing behavior of a reportedly strongly monogamous quail, the king quail (Coturnix chinensis, a species in the same clade as the less monogamous Japanese quail (Coturnix japonica, the subject of much prior research. In Experiment 1 male-female pairs of king quail housed together were initially avoidant or aggressive but most rapidly progressed to allopreening and huddling. A separation-reunion paradigm reliably elicited both of these behaviors in males that had cohabited for one week. In Experiment 2 the allopreening and huddling behavior of males in cohabiting pairs was highly selective, and a majority of the males were aggressive toward a familiar female that was not the cohabitation partner. In Experiment 3 males were separated from their female cohabitation partners for 9-10 weeks and then given two-choice tests. All but one male spent more time near an unfamiliar female, which may have reflected aggression and shows recognition of and memory for the past pairing experience. Thus king quail show robust, selective and easy to measure pairing behavior that can be reliably elicited with simple separation-reunion testing procedures. Copulation is rarely seen during tests. The behavior of king quail is a striking contrast to that of Japanese quail, providing a new comparative system for discovering mechanisms of behavior related to close social relationships and monogamy.

Full Text Available Aim: The present study was conducted to evaluate the performance of gray, brown, and white varieties of Japanese quail (Coturnix coturnix japonica with respect to body weight, egg production, and egg quality traits in the coastal climatic condition of Odisha. Materials and Methods: A total of 500-day-old straight run Japanese quail chicks of three varieties, viz., gray, brown, and white were randomly selected and reared in deep litter system at Central Poultry Development Organization, Eastern Region, Bhubaneswar. The weekly body weight of the birds was recorded till their egg production stage (up to 6 weeks of age. The average egg production was recorded every biweekly from 6th to 20th week. Exterior and interior quality of eggs from each variety was determined at 6 weeks of age. Results: The initial average weekly body weight of three varieties did not differ (p>0.05 among the varieties. However, from 1st to 6th week significantly higher body weight was observed in gray than white and brown. Brown varieties had reached 50% egg production 1 week earlier than gray and white.

Full Text Available Aim: The objective of this study was to evaluate the effect of feeding fermented fish silage (FFS on serum biochemical parameters of Japanese quails (Coturnix coturnix japonica. Materials and Methods: A total of 192, 7-day-old broiler Japanese quail chicks of either sex, were randomly distributed into four dietary treatments with four replicates in each group having 12 chicks in each replicate pen. The dietary treatments were T1 - Control diet, T2 - Diet containing 5% FFS, T3 - Diet containing 10% FFS, and T4 - Diet containing 15% FFS. Group body weight and feed consumption were recorded at weekly intervals. Feed conversion ratio (FCR was derived by dividing the feed consumed with the weekly body weight gain. At the end of the experiment, 8 birds from each treatment were selected randomly and sacrificed by cervical dislocation to study the carcass traits expressed as % pre-slaughter live weight. At 5 weeks of age, about 2 ml of blood was taken from the jugular vein of each selected bird, and serum samples were separated after centrifugation. Total protein, albumin/globulin (A/G ratio, calcium, phosphorus, triglyceride, total cholesterol, high density lipoprotein-cholesterol (HDL-C, very low density lipoprotein-cholesterol (VLDL-C, low density lipoprotein-cholesterol (LDL-C, alanine aminotransferase (ALT, and aspartate aminotransferase (AST were estimated in the serum. Results: The cumulative body weight gains from 1 to 5 weeks of age did not vary significantly between control and 5% FFS group. However, a linear decrease in body weight gain was observed by increasing the levels of FFS beyond 5% in the diet. The cumulative feed consumption was significantly higher in case of birds under control group during 1-5 weeks of age as compared to birds fed FFS based diet (5%, 10%, and 15%. No statistical difference in cumulative feed conversion ratio could be noticed during 1-5 weeks of age. The eviscerated yield decreased and giblet weight increased due

Reproductive disease in captive avian species is common, and medical management is often chosen over surgical removal of the reproductive tract. In a previous study with Japanese quail, a single 4.7-mg deslorelin acetate implant reversibly decreased egg production in 6 out 10 birds for 70 days. The objective of the current study was to evaluate the effects of two 4.7-mg deslorelin acetate implants versus one 9.4-mg implant on egg production and plasma progesterone concentrations in Japanese quail ( Coturnix coturnix japonica). Following a 10-day period of consistent egg laying, 30 adult female Japanese quail were anesthetized and received two 4.7-mg deslorelin implants (n = 10), one 9.4-mg deslorelin implant (n = 10), or a single, identical placebo implant (n = 10) s.c. between the scapulae. Egg production was monitored daily, and plasma progesterone concentrations were measured on days 0, 14, 29, 120, 148, and 182 via enzyme-linked immunoassay. All birds were weighed periodically and euthanized at day 182, after which their reproductive tracts were evaluated at gross necropsy. Seven out of 10 birds treated with two 4.7-mg implants ceased egg laying 1 wk after implantation and remained nonovulatory for approximately 100 days. Cessation of egg laying for the 9.4-mg treatment group occurred in 7 out of 10 birds; onset was variable (weeks 5-12) and continued for the remainder of the study period. Plasma progesterone concentrations for deslorelin treatment groups were not significantly different compared to the placebo group at any time point. In conclusion, the two 4.7-mg and the one 9.4-mg implant treatments ceased egg laying in a similar number of birds, but the 9.4-mg implant had a slower onset of action and the effects on egg laying were inconsistent throughout the study period. Further studies evaluating use of deslorelin acetate in other avian species are needed.

Coturnix chinensis (blue-breasted quail) has been classically grouped in Galliformes Phasianidae Coturnix, based on morphologic features and biochemical evidence. Since the blue-breasted quail has the smallest body size among the species of Galliformes, in addition to a short generation time and an excellent reproductive performance, it is a possible model fowl for breeding and physiological studies of the Coturnix japonica (Japanese quail) and Gallus gallus domesticus (chicken), which are classified in the same family as blue-breasted quail. However, since its phylogenetic position in the family Phasianidae has not been determined conclusively, the sequence of the entire blue-breasted quail mitochondria (mt) genome was obtained to provide genetic information for phylogenetic analysis in the present study. The blue-breasted quail mtDNA was found to be a circular DNA of 16,687 base pairs (bp) with the same genomic structure as the mtDNAs of Japanese quail and chicken, though it is smaller than Japanese quail and chicken mtDNAs by 10 bp and 88 bp, respectively. The sequence identity of all mitochondrial genes, including those for 12S and 16S ribosomal RNAs, between blue-breasted quail and Japanese quail ranged from 84.5% to 93.5%; between blue-breasted quail and chicken, sequence identity ranged from 78.0% to 89.6%. In order to obtain information on the phylogenetic position of blue-breasted quail in Galliformes Phasianidae, the 2,184 bp sequence comprising NADH dehydrogenase subunit 2 and cytochrome b genes available for eight species in Galliformes [Japanese quail, chicken, Gallus varius (green junglefowl), Bambusicola thoracica (Chinese bamboo partridge), Pavo cristatus (Indian peafowl), Perdix perdix (gray partridge), Phasianus colchicus (ring-neck pheasant), and Tympanchus phasianellus (sharp-tailed grouse)] together with that of Aythya americana (redhead) were examined using a maximum likelihood (ML) method.

Full Text Available La globalización cultural propia de nuestros tiempos produce un camino con doble sentido: no sólo Occidente exporta al resto del mundo sus modelos culturales, sino que el modo de hacer de otras culturas entra en Europa y EEUU. Y una de las culturas que más interés despierta en los últimos años es la cultura japonesa. Esto es, en parte, gracias a la excelente exportación que se ha realizado del manga. Al igual que el cómic occidental refleja los valores de la sociedad que lo crea, el cómic japonés es un reflejo de la sociedad japonesa. Se refleja en las historias que cuenta y en el modo que tiene de hacerlo. Como cualquier otro medio de expresión, el manga tiene su propio lenguaje icónico y textual, condicionado por los cánones estéticos y éticos de la cultura en la que se produce. Así, nos vamos a acercar a la sociedad japonesa por medio del manga, de su historia, su origen y desarrollo, y de sus cualidades estéticas y narrativas.Cultural globalization in our days creates a twofold road: not only have the West exported their cultural models to the rest of the world, but there is also an influence from other cultures in Europe and the USA. And one of the cultures that have attracted more interest is the Japanese culture. This is, in part, due to the great contribution made by Manga. In the same way that western comic is a reflection of the society that creates it, Japanese comic is a reflection of the Japanese society. This influence can be seen both in the stories told and the way to do so. As any other way of expression, Manga have its own iconic and textual language, influenced by the aesthetic and ethical canons from the culture where it comes from. Therefore, we will try to approach the Japanese society through Manga, its history, origin and development, and also its narrative and aesthetic qualities.

Full Text Available Cincuenta años más tarde de la llegada de las primeras cinco familias de japoneses al puerto de Buenaventura, Eugenio Bamey dio fin a la elaboración de una obra en la que rastrea las posibles influencias de los diferentes grupos de inmigrantes en los hábitos alimentarios de la población vallecaucana. Al núcleo japonés, aunque le reconoce su destacado papel en la evolución de la técnica agricola regional, no le encuentra mayor significado como elemento aportante en las costumbres culinarias. Sin embargo, ya era frecuente en Cali el consumo popular de helado de soya, que se expende empacado en bolsas de polietileno, a bajos precios, en diferentes esquinas de la ciudad. ¿Y el seviche de camarón, que procede de la cocina japonesa, y que ha hecho su tránsito al valle caucano desde la costa peruana, no ha llegado para instalarse definitivamente como plato típico? Estos dos ejemplos muestran cómo la influencia cultural japonesa es más fuerte de lo que comúnmente se piensa y abarca territorios que van más allá de los habituales referentes a la actividad agropecuaria.

Full Text Available The Japanese quail Coturnix japonica originated from North Africa, Europe and Asia, is used worldwide as an experimental animal and model for aviculture. The current paper characterizes Eimeria bateri, Eimeria tsunodai and Eimeria uzura recovered from C. japonica. Based on the fact that quails have a global distribution, as are their coccidia, the findings of this study should provide the means for diagnosis of those Eimeria spp. in other regions and continents. Eimeria bateri showed the greatest intensity of infection and shed oocysts from the fourth day after infection; in contrast, E. tsunodai and E. uzura shed oocysts from the fifth day after infection. The three species shared a high degree of similarity and were all polymorphic. Yet, the application of line regressions, histograms and ANOVA provided means for the identification of these species. Finally, the algorithm was very efficient since verified that resultant values were not superimposed.

Três foram as principais causas desse processo: 1 Uma política contínua em prol da imigração japonesa para o Peru durante as primeiras décadas do século XX voltada para prover mão-de-obra nas fazendas de cana-de-açúcar e algodão da costa; 2 Envolvimento dos imigrantes japoneses em atividades econômicas demandadas durante a expansão da exploração da borracha na Amazônia peruana; e 3 Fortalecimento dessas atividades após a queda da economia da borracha para garantir o fornecimento de produtos necessários à população remanescente, inclusive, substituindo produtos não mais importados ou fornecidos por grandes empresas. A Amazônia peruana tornou-se cada vez mais atrativa para os imigrantes japoneses inconformados com as más condições de trabalho nas fazendas da costa, engrossando assim a migração para essa região. A própria existência de uma comunidade mais ou menos organizada que serviu de suporte na Amazônia peruana permitiu fortalecer a vinda de mais migrantes. Em Puerto Maldonado, os japoneses se dedicaram à produção de hortifrutigranjeiros e outros produtos agrícolas para suprir o mercado local, estabeleceram pequenos comércios, e forneciam alguns serviços especializados

The authors describe a spontaneous case of amyloid A (AA) amyloidosis in an adult female Japanese quail ( Coturnix japonica). The bird developed AA amyloidosis secondary to chronic peritonitis caused by a Gram-negative bacillus infection. Mild amyloid deposition was also identified in the intestinal tract of apparently healthy adult individuals, suggesting that quail may develop intestinal amyloidosis with age. Based on these observations, it was hypothesized that quail can develop AA amyloidosis following inflammatory stimulation with lipopolysaccharide (LPS). Therefore, adult quail were repeatedly injected with LPS and the development of AA amyloidosis was confirmed. The amyloid deposition in this model increased when quail amyloid was intravenously injected as an amyloid-enhancing factor. The experiments were repeated with young quail, but amyloid deposits were not observed following LPS injections. However, AA amyloidosis did develop when quail amyloid was injected in addition to LPS. These results indicated that adult quail develop AA amyloidosis after inflammatory stimulation with LPS. Furthermore, quail AA amyloidosis was shown to have transmissibility regardless of age. Interestingly, the authors found that administration of chicken amyloid fibrils also induced AA amyloidosis in young quail. This is the first report of cross-species transmission of avian AA amyloidosis.

Full Text Available Objetivou-se avaliar o desempenho de codornas japonesas na fase de postura alimentadas com dietas contendo soja integral processada. Utilizaram-se 320 codornas japonesas fêmeas com 29 semanas de idade e peso inicial de 186,1 ± 4,0 g, distribuídas em delineamento inteiramente casualizado, com oito repetições, cada uma com dez aves por unidade experimental. As dietas foram isocalóricas e isonutritivas para proteína bruta, lisina digestível, metionina + cistina digestível, cálcio, fósforo disponível e sódio. Assim, foram avaliadas uma dieta controle, à base de milho e farelo de soja, e outras três, com substituição parcial do farelo de soja por soja integral tostada, extrusada ou micronizada, de modo que a soja integral forneceu 50% da proteína bruta proporcionada pelo farelo de soja na dieta controle. Não foram observadas diferenças na produção e na massa de ovos, na conversão alimentar, na viabilidade das aves, na porcentagem de ovos comercializáveis, no peso específico dos ovos, na porcentagem de gema e de albúmen nem na porcentagem de casca dos ovos. A substituição de farelo de soja por soja integral tostada ocasionou redução no consumo de ração. Não foram observadas diferenças nos parâmetros estudados quando o farelo de soja foi substituído por soja integral extrusada. A substituição de farelo de soja por soja integral micronizada reduziu a variação de peso corporal das codornas, resultando em perda de peso das aves. O farelo de soja pode ser substituído, em 50% da proteína, por soja integral tostada ou extrusada em dietas para codornas japonesas em postura. Entretanto, a substituição do farelo de soja por soja integral micronizada, em 50% da proteína, é desaconselhável, pois piora o desempenho, ocasionando principalmente perda de peso das aves.This work aimed at evaluating the performance of Japanese quails fed diets with processed whole soybean during the laying phase.

Os níveis avaliados foram: 16, 18, 20 e 22% de proteína bruta e 2.585, 2.685, 2.785 e 2.885 kcal de energia metabolizável/kg de ração. Não houve efeito significativo dos tratamentos sobre a ingestão de energia e a produção de ovos. Entretanto, o aumento do nível de energia da ração promoveu redução linear no consumo de ração, na ingestão diária de proteína bruta, no peso do ovo e na massa de ovos, enquanto o de proteína proporcionou aumento linear na ingestão diária de proteína bruta, na massa de ovos, na conversão alimentar e no ganho de peso corporal e efeito quadrático sobre o peso do ovo, sendo 21,16% o nível de proteína bruta estimado para a obtenção do máximo peso do ovo. Pode-se concluir que as codornas japonesas têm o consumo regulado em função do nível de energia da ração. Para se obter maior produção de ovos e melhor conversão alimentar, a ração de postura deve conter 18% de proteína bruta e 2.585 kcal de EM/kg. Entretanto, se o objetivo for a obtenção de ovos com peso mais elevado, o nível de proteína bruta da ração deve aumentar para 21,16%.This work was developed to evaluate the effect of different levels of crude protein (CP and metabolizable energy (ME on the performance of laying quails.

The sublethal toxicity of inorganic (HgCI 2) and organic (CH3HgCI) mercury chloride was studied in coturnix (Corurnix japonica) by feeding them mercuric compounds (CH3HgCI at concentrations of 0.125,0.5,2 and 8 ppm; HgCI2 at 0.5, 2, 8 and 32 ppm) in ad libitum diets from hatching to adulthood. Differences of response to the mercurials were compared on the basis of selected indicator enzymes and plasma chemistries. Comparisons of response to equivalent concentrations of the two mercurials and dose-response relationships were made at 1,3,5,7 and 9 weeks. Changes of activity were detected for brain acetylcholinesterase (AChE) and the plasma enzymes aspartate aminotransferase (ASA T), butyrylcholinesterase (BChE), lactate dehydrogenase (LDH) and ornithine carbamoyl transferase (OCT). Changes of ASA T, LDH and OCT were then quantified by probit analysis and the mercurials were compared through their median effective concentrations (EC50). This quantal procedure was based on the establishment of normal control values for each enzyme and then classifying mercury-treated outliers (more than + 2 SD) as respondents. The EC50 values at 9 weeks for ASA T, LDH and OCT, respectively, were 9, 3 and 63 ppm for HgCl 2, and 5, 1 and 4 ppm for CH3HgCI. These results provided the basis for two hazard indices that were calculated by dividing the EC50 into the oral LD50 and the 5-d dietary LC50. Mercury also had contradictory effects on gonadal maturation in both sexes.

Full Text Available Antibacterial, anti-inflammatory and antiparasitic properties have been associated with the extract of pomegranate (Punica granatum in several animals and conditions. The Japanese quail (Coturnix japonica, originated from North Africa, Europe and Asia, is used worldwide as an experimental animal and model for aviculture. The current study investigated the effects of the pomegranate pericarp aqueous extract on the shedding, viability and morphometry of three Eimeria spp. from Japanese quails, besides the weight gain and genotoxic activity. Although the pomegranate is recognized by multiple properties, including anti-coccidial, in the current study the results are contrary. The treated group shed greater amount of oocysts; the sporulation times and viability were similar in both groups; despite some morphometric differences, these were not expressive; weight gains were similar; and the pomegranate had insignificant effect genotoxic. Finally, these results suggest that the pomegranate pericarp extract did not influence on Eimeira spp. from Japanese quails; therefore, the pomegranate pericarp extract is not suggested in the prevention/treatment of coccidiosis in Japanese quails, or at least not using methods of preparation and administration applied in this study.

Aspergillosis is a common fungal infection in both wild and pet birds. Although effective antifungal medications are available, treatment of aspergillosis can require months of medication administration, which entails stressful handling one or more times per day. This study examined the delivery of the antifungal drugs itraconazole, voriconazole, and terbinafine to Japanese quail ( Coturnix japonica ) via an impregnated implant. Implants contained 0.5, 3, 8, or 24 mg of itraconazole, voriconazole, or terbinafine. The implants were administered subcutaneously over the dorsum and between the scapulae. Blood was collected from birds before and 2, 7, 21, 42, and 56 days after implant placement. Plasma was analyzed by high-performance liquid chromatography for concentrations of itraconazole, voriconazole, or terbinafine, as appropriate. During the course of the study, targeted terbinafine concentrations were achieved in some birds at various time points, but concentrations were inconsistent. Itraconazole and voriconazole concentrations were also inconsistent and did not reach targeted concentrations. Currently, the implant examined in this study cannot be recommended for treatment of aspergillosis in avian species.

Divergent lines of Japanese quail Coturnix japonica showing high (HSR) or low (LSR) levels of social reinstatement (SR) behaviour (as measured in a treadmill apparatus) have been developed. However, it was not known if selection had influenced social reinstatement tendencies in a general or a species-specific fashion. Therefore, the present study compared the SR behaviour of quail chicks of the HSR and LSR lines and of a Control line when the goal box of the treadmill was empty or when it contained small, same-species groups of either Japanese quail, domestic fowl or Guinea fowl chicks. The results clearly demonstrated that the SR behaviour of Japanese quail chicks is species-specific and that this specificity has not been influenced during genetic selection, over sixteen generations, of the HSR and LSR lines. The HSR chicks showed more locomotor activity in the treadmill than did those of the other lines regardless of the nature of the goal-box stimulus. The results are discussed in terms of general activity, underlying fearfulness and social motivation.

Phenotypic plasticity of organ size allows some animals to manage fluctuations of resource quality or availability. Here, we examined the phenotypic plasticity of the gastrointestinal tract of king quail (Coturnix chinensis) in a diet-fibre manipulation study. Quail were offered either a control low-fibre (high-quality) food (8.5% neutral-detergent fibre; NDF), or one of two experimental diets of higher fibre contents of 16% NDF (i.e. low-quality food). To examine whether phenotypic plasticity of organ size was associated with the fibre content per se, or as a consequence of diluting the diet energy contents by adding fibre, one of the high-fibre feeds was 'balanced' with additional energy to match that of the low-fibre control diet. Total empty dry mass of the gastrointestinal tract was significantly heavier among birds offered the unbalanced high-fibre diet as compared with those offered the control diet, with birds offered the fibrous but energy-balanced diet having guts of intermediate size. The heavier entire-gut mass (dry) of quail offered the unbalanced high-fibre diet was associated mainly with these birds having significantly heavier gizzards. Notably, the larger gizzard in the birds offered the unbalanced high-fibre diet was associated with marked increases in their metabolisability (digestion) of diet fibre. Our findings suggest that the available energy in the diet may be more important for eliciting phenotypic changes in the gut of these herbivorous birds rather than simple physical effects of diet fibre on feed intakes or on muscular compensation to fibrous ingesta. © 2014.

No evidence for sex-specific effects of the maternal social environment on offspring development in Japanese quail (Coturnix japonica).

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. However, results are not consistent across studies and therefore still inconclusive. In Japanese quail (Coturnix japonica), we previously found that pair-housed females had higher plasma androgen levels and tended to have higher plasma corticosterone levels than group-housed females. In the current study we investigate whether these differences in maternal social environment and physiology affect offspring sex allocation and physiology. Counter to our expectations, we find no effects of the maternal social environment on offspring sex ratio, sex-specific mortality, growth, circulating androgen or corticosterone levels. Also, maternal corticosterone or androgen levels do not correlate with offspring sex ratio or mortality. The social environment during reproduction therefore does not necessarily modify sex allocation and offspring physiology, even if it causes differences in maternal physiology. We propose that maternal effects of the social environment strongly depend upon the type of social stimuli and the timing of changes in the social environment and hormones with respect to the reproductive cycle and meiosis.

Veritable identification and differentiation of avian species is a vital step in conservative, taxonomic, forensic, legal and other ornithological interventions. Therefore, this study involved the application of molecular approach to identify some avian species i.e. Chicken (Gallus gallus), Muskovy duck (Cairina moschata), Japanese quail (Coturnix japonica), Laughing dove (Streptopelia senegalensis), and Rock pigeon (Columba livia). Genomic DNA was extracted from blood samples and partial sequence of the mitochondrial cytochrome b gene (358 bp) was amplified and sequenced using universal primers. Sequences alignment and phylogenetic analyses were performed by CLC main workbench program. The obtained five sequences were deposited in GenBank and compared with those previously registered in GenBank. The similarity percentage was 88.60% between Gallus gallus and Coturnix japonica and 80.46% between Gallus gallus and Columba livia. The percentage of identity between the studied species and GenBank species ranged from 77.20% (Columba oenas and Anas platyrhynchos) to 100% (Gallus gallus and Gallus sonneratii, Coturnix coturnix and Coturnix japonica, Meleagris gallopavo and Columba livia). Amplification of the partial sequence of mitochondrial cytochrome b gene proved to be practical for identification of an avian species unambiguously. PMID:27175180

This study relates tissue concentrations and toxic effects of Pb in Japanese quail (Coturnix japonica) to the dietary exposure of soil-borne Pb associated with mining and smelting. From 0% to 12% contaminated soil, by weight, was added to 5 experimental diets (0.12 to 382 mg Pb/kg, dry wt) and fed to the quail for 6 weeks. Benchmark doses associated with a 50% reduction in delta-aminolevulinic acid dehydratase activity were 0.62 mg Pb/kg in the blood, dry wt, and 27 mg Pb/kg in the diet. Benchmark doses associated with a 20% increase in the concentration of erythrocyte protoporphyrin were 2.7 mg Pb/kg in the blood and 152 mg Pb/kg in the diet. The quail showed no other signs of toxicity (histopathological lesions, alterations in plasma–testosterone concentration, and body and organ weights). The relation of the blood Pb concentration to the soil Pb concentration was linear, with a slope of 0.013 mg Pb/kg of blood (dry wt) divided by mg Pb/kg of diet. We suggest that this slope is potentially useful in ecological risk assessments on birds in the same way that the intake slope factor is an important parameter in risk assessments of children exposed to Pb. The slope may also be used in a tissue-residue approach as an additional line of evidence in ecological risk assessment, supplementary to an estimate of hazard based on dietary toxicity reference values.

Full Text Available ABSTRACT Quail is an important and interesting group of galliform birds. The Common quail (Coturnix coturnix; the Japanese quail (Coturnix japonica; the Panda quail (Coturnix japonica; the Dotted white quail (Coturnix japonica and the Bobwhite quail (Colinus virginianus were used in this study. PCR-RFLP and SDS-proteins were performed to reveal the genetic characterization and genetic relationship of the studied quails. Analysis of fragments generated by digestion of PCR product with restriction enzyme NlaIII recorded highly polymorphic restriction profiles. There is a wide intraspecific COI, SEMA3E and TLX genes variability among the studied quails. Protein bands varied from10 to 18 between quails with minimum number of bands were in the Dotted white quail (10 bands and the maximum were in the Japanese quail (18 bands as measured by SDS-polyacrylamide gel electrophoresis. The Dotted white quail revealed the lowest similarity to the Bobwhite with a coefficient of 0.18 while The similarity coefficients between the Common quail and each one of the other quails were 0.67, 0.62, 0.45 and 0.42 for the Japanese, Panda, Dotted white and the Bobwhite quails, respectively. The results indicate that, PCR-RFLP and protein analyses are good techniques to evaluate genetic characterization and genetic relationship of these quails.

¿Más allá de “subcultura”? Apuntes sobre el fanatismo por la animación japonesa desde los planteos de Dick Hebdige

Full Text Available El presente texto se propone problematizar la aplicación del concepto de subcultura en el análisis de las dinámicas de construcción identitaria y producción simbólica que tienen lugar a partir del consumo fan de series animadas japonesas –anime– por parte de jóvenes habitantes de Buenos Aires. Dicho objetivo responde a que se considera que el abordaje de los grupos o colectivos de fanáticos en general, y de los otakus en particular –fans de los objetos de la cultura de masas proveniente de Japón–, en términos de subculturas, tiende a prescribirles cierta orientación de “resistencia”, influida por los estudios culturales británicos y la obra de Hebdige. A su vez, se entiende que en el campo académico de estudios sobre estos fans, aún en vías de constitución, suele predominar la utilización de dicha noción sin desarrollar una problematización teórico-conceptual al respecto. Las reflexiones que aquí se plantean, entonces, parten de una investigación propia sobre las identidades culturales que construyen y los sentidos que producen los otakus sobre sus prácticas de consumo, la cual asume una perspectiva comunicacional y socioantropológica, e implica la aplicación de técnicas de observación participante y entrevistas abiertas, tanto cara a cara como vía plataformas digitales, para reconstruir su propio punto de vista.

Social environment during egg laying: Changes in plasma hormones with no consequences for yolk hormones or fecundity in female Japanese quail, Coturnix japonica.

Directory of Open Access Journals (Sweden)

Esther M A Langen

Full Text Available The social environment can have profound effects on an individual's physiology and behaviour and on the transfer of resources to the next generation, with potential consequences for fecundity and reproduction. However, few studies investigate all of these aspects at once. The present study housed female Japanese quail (Coturnix japonica in pairs or groups to examine the effects on hormone concentrations in plasma and yolk and on reproductive performance. Circulating levels of androgens (testosterone and 5-α-dihydrotestosterone and corticosterone were measured in baseline samples and after standardised challenges to assess the responsiveness of the females' endocrine axes. Effects of the social environment on female fecundity were analysed by measuring egg production, egg mass, fertilization rates, and number of hatched offspring. Counter to expectation, females housed in pairs had higher plasma androgen concentrations and slightly higher corticosterone concentrations than females housed in groups, although the latter was not statistically significant. Pair vs. group housing did not affect the females' hormonal response to standardised challenges or yolk testosterone levels. In contrast to previous studies, the females' androgen response to a gonadotropin-releasing hormone challenge was not related to yolk testosterone levels. Non-significant trends emerged for pair-housed females to have higher egg-laying rates and higher fertility, but no differences arose in egg weight or in the number, weight or size of hatchlings. We propose that our unexpected findings are due to differences in the adult sex ratio in our social treatments. In pairs, the male may stimulate female circulating hormone levels more strongly than in groups where effects are diluted due to the presence of several females. Future studies should vary both group size and sex composition to disentangle the significance of sexual, competitive and affiliative social interactions for

The current research was conducted to compare growth, carcass traits, pH, intramuscular collagen (IMC) properties, and genetic bases of IMC and carcasses (breast-muscle weight) of different lines and generations of adult males and females of Japanese quail (Coturnix japonica). Forty-four quails (generation F0), 22 Pharaoh (F-33) meat-type males and 22 Standard (S-22) laying-type females, were crossed to produce the F1 hybrids generation. The F2 generation was created by mating one F1 male with one F1 female, full siblings. The birds, randomly chosen from F0 (22 males and 22 females), F1 (22 males and 22 females), and F2 (84 males and 152 females) were raised to 20 wk of age in collective cages. Quails were fed ad libitum commercial diets. At slaughter, all birds were individually weighed (after a fasting period of 12 h) and dressing yield (without giblets) was calculated. The carcasses were then dissected. Genomic DNA was extracted from all of the blood, and 30 microsatellite markers located on 2 quail chromosomes were genotyped. The F -: 33 quails had higher in vivo and postmortem performances and a higher abdominal fat percentage than those of the egg line. Meat from S -: 22 quails had a slower collagen maturation (hydroxylysylpyridinoline crosslink/collagen) and a higher ultimate pH. The F1 and F2 generations showed an evident sexual dimorphism, and an additional effect could be due to hybrid heterosis evident in F2. Meat from quails of F1 and F2 generations had a lower IMC amount with a higher degree of collagen maturation compared with parental lines. Two statistically significant QTL have been detected on quail chromosome 2 (CJA02): a QTL with an additive effect (0.50) for IMC in the marker bracket GUJ0037 and GUJ0093; a second QTL with additive (1.32) and dominant (1.91) effects for breast-muscle weight in the marker bracket GUJ0084 and GUJ0073. To our knowledge, this is the first report of a QTL associated with breast-muscle weight and IMC in quail and

Foram utilizadas 350 codornas, com 313 dias de idade, distribuídas em 35 unidades experimentais de 10 aves. O delineamento foi inteiramente ao acaso, composto de cinco níveis de Ca - 2,2; 2,6; 3,0; 3,4; 3,8% -, com sete repetições. O aumento do Ca na dieta melhorou linearmente a conversão por massa e por dúzia de ovos, melhorou a espessura de casca e influenciou o peso da gema e da casca dos ovos, além da porcentagem da casca. Observou-se redução nos teores de P, Ca e Mg na casca com o aumento dos níveis de Ca da dieta. Para os demais parâmetros, não houve efeito do teor de Ca da dieta. Considerando-se a importância da conversão alimentar, em termos econômicos e de desempenho, o teor de 3,8% de Ca na dieta mostrou-se satisfatório em atender às demais variáveis relacionadas com a qualidade dos ovos. Dieta que contenha 3,8% de Ca, correspondendo ao consumo diário de 982mg por ave, melhora a conversão alimentar e a qualidade da casca dos ovos de codornas japonesas no terço final do ciclo de produção (45 a 57 semanas de idade.The effect of calcium (Ca levels in the diet on performance and egg quality of Japanese quail during the final third of the production cycle was evaluated.

The effects of increasing levels of soybean acid oil in diets of quails on the quality of eggs were evaluated over a period of 56 days. A completely randomized design with five treatment levels of soybean acid oil (0, 2, 4, 6, and 8%) as a replacer for soybean oil and eight replicates of two quails each were used. A total of 240 fresh eggs were used for quality analysis, and 400 eggs were stored at 23ºC over a period of 0, 7, 14, 21, and 28 days for analysis of shelf-life. Polynomial regression and ANOVA with repeated measurements and Tukey´s tests were used. Soybean acid oil linearly increased the intensity of red (a* = -5.26 + 0.14 x, R2 = 0.89, P = 0.01) and yellow (b* = 42.32 + 0.44 x, R2 = 0.88 P = 0.01). All other variables of egg quality were not affected by the treatments, with the exception of sensory attributes, such as odor and aftertaste, which were more pronounced with soybean acid oil. In conclusion, soybean acid oil affects the intensity of yellow and red color of the yolk. Trained assessors detected differences in odor and aftertaste of eggs when soybean acid oil was included in the quail diet.

Full Text Available The objective of this work was to evaluate the relationships of methionine plus cystine with lysine for Japanese quails in the laying phase. Thus, it was used 480 birds at initial age of 65 days, distributed in randomized block design with 6 treatments, 10 replicates and 8 birds per experimental unit. The treatments consisted of basal diet deficient in methionine plus cystine (0.65%, with 19.6% of crude protein and 2800 kcal of metabolizable energy/kg of ration, supplemented with six levels of DL-methionine 98% (0.116; 0.167; 0.218; 0.269; 0.320 and 0.371%, corresponding to methionine plus cystine with lysine ratio of 0.65, 0.70, 0.75, 0.80, 0.85 and 0.90, and the digestible lysine set at a suboptimal level of 1.00. The parameters studied were: feed intake, egg production per hen day, egg production per housed hen, commercial egg production, egg weight, egg mass, feed conversion per egg mass, feed conversion per dozen eggs, viability of birds, weight of the egg components (yolk, albumen and shell, percentage of components of eggs, diameter and height of the eggs and specific gravity. It was observed an increasing linear effect for feed intake, egg diameter, shell weight and percentage of yolk. For eggshell percentage, it was observed a decreasing linear effect. For the weight of the eggs, the best adjustment was obtained by using the Linear Response Plateau model. A quadratic effect was observed for egg mass, feed conversion per egg mass, egg production per hen day, egg production per housed hen, yolk weight, albumen weight and height of the eggs. The relationship of methionine plus cystine with lysine of 0.84 which corresponds to the consumption of 221.0 mg/bird/day of methionine + cystine provides better performance and satisfactory quality of Japanese quail eggs.Com o objetivo de avaliar o efeito de relações entre metionina mais cistina com lisina para codornas japonesas na fase de postura, 480 aves com idade inicial de 65 dias foram

Full Text Available In the present study Salmonella spp. was surveyed in four flocks of meat-type quails reared in a farm that also had processing plant on site, located in the region of Bastos, state of São Paulo, Brazil. Meconium samples of one-day-old quail chicks were collected from transport cardboard boxes. Cecal content was collected on days 7, 14, 21, 28 and 35 of rearing. At 36 days of age, birds were slaughtered in the farm's processing plant, where two samples of water from the scalding and the chilling tanks and four carcasses per flock were collected. All samples were examined for Salmonella spp. using traditional bacteriological methods. Salmonella spp. was present in meconium samples of three flocks and in cecal feces of the four flocks. This bacterium was also isolated in the chiller water and in the carcasses of three of the evaluated flocks and in the scalding water of one flock. In this study, S. enterica subspecies enterica 4, 5, 12; S. Corvalis; S. Give; S. Lexington; S. Minnesota; S. Schwarzengrund; S. Rissen and S. Typhimurium were the eight serovars identified.

The present study sought to assess the potential application of avian models with different developmental modes to studies on cognition and neuroscience. Six altricial Bengalese finches (Lonchura striata var. domestica), and eight precocial blue-breasted quails (Coturnix chinensis) were presented with color discrimination tasks to compare their respective faculties for learning and memory retention within the context of the two developmental modes. Tasks consisted of presenting birds with discriminative cues in the form of colored feeder lids, and birds were considered to have learned a task when 80% of their attempts at selecting the correctly colored lid in two consecutive blocks of 10 trials were successful. All of the finches successfully performed the required experimental tasks, whereas only half of the quails were able to execute the same tasks. In the learning test, finches required significantly fewer trials than quails to learn the task (finches: 13.5 ± 9.14 trials, quails: 45.8 ± 4.35 trials, P memory retention tests, which were conducted 45 days after the learning test, finches retained the ability to discriminate between colors correctly (95.0 ± 4.47%), whereas quails did not retain any memory of the experimental procedure and so could not be tested. These results suggested that altricial and precocial birds both possess the faculty for learning and retaining discrimination-type tasks, but that altricial birds perform better than precocial birds in both faculties. The present findings imply that developmental mode is an important consideration for assessing the suitability of bird species for particular experiments. © 2013 Japanese Society of Animal Science.

Particular emphasis was placed on testing the hy pothesis that there would be differences between household use of HPS prevention measures based on the head-of-household's knowledge of HPS. METHODS: A questionnaire was designed in three sections: (1 household demographic char acteristics, (2 HPS knowledge, and (3 HPS preventive measures. Questionnaires were given to the household head or other adult representing the household at an HPS prevention semi nar sponsored by the Japanese Association of La Plata in February 2007. Total HPS knowl edge scores were dichotomized into high (equal to or more than the median knowledge score and low (less than the median. Differences between the two household groups were catego rized, according to the degree of HPS knowledge, and analyzed. RESULTS: The 86 households that responded accounted for about 72% of the total study households in the area. The median knowledge score of 5 (range: 0-9, of 10 divided the study households into two groups: high knowledge score group (n = 40 and low knowledge score group (n = 46. The findings suggest an association between a household's accurate HPS knowledge and its respective use of HPS preventive measures.

Full Text Available Na cirurgia ortopédica, são freqüentes as situações em que o cirurgião se depara com grandes perdas ósseas, provocadas especialmente por traumatismos de alta energia, tumores ou infecções. A reparação dessas fraturas requer grande conhecimento a respeito de materiais que possam ser utilizados para preencher essas falhas. Esses materiais podem ser derivados biológicos, sintéticos ou metálicos. Dentre eles, destacam-se os enxertos ósseos e os implantes de biomateriais. Com o aumento dos animais exóticos, utilizados como animais de estimação, a casuística clínica e cirúrgica dessa especialidade vem crescendo, tanto em clínicas quanto em hospitais veterinários. Particularmente, as aves constituem a maioria desses animais, e entre seus problemas cirúrgicos as fraturas são os de maior destaque. O objetivo deste trabalho foi estudar o efeito clínico, radiológico, macroscópico e histológico da poliuretana derivada do polímero de mamona (Ricinnus communis implantada no úmero de codornas domésticas (Coturnix japonica. Para isso, foram utilizadas 20 codornas, machos e fêmeas, separadas aleatoriamente em quatro grupos de cinco animais, os quais receberam o implante no úmero esquerdo, com exame clínico diário durante o período pós-operatório, avaliações radiológica imediata e quinzenal e macroscópica e histológica aos 15, 30, 60 e 90 dias.

There has been a gradual increase in production and consumption of atrazine (ATR) in agriculture to meet the population rising demands. Female reproduction is necessary for growth and maintenance of population. However, ATR impact on females and particularly ovarian developmental toxicity is less clear. The aim of this study was to define the pathways by which ATR exerted toxic effects on ovarian development of ovary and hypothalamo-pituitary-ovarian (HPO) axis. Female quails were dosed by oral gavage from sexual immaturity to maturity with 0, 50, 250 and 500 mg ATR/kg/d for 45 days. ATR had no effect on mortality but depressed feed intake and growth and influenced the biochemical parameters. Notably, the arrested development of ovaries and oviducts were observed in ATR-exposed quails. The circulating concentrations of E2, P, LH and PRL were unregulated and FSH and T was downregulated in ATR-treated quails. The mRNA expression of GnRH in hypothalamo and LH in pituitary and FSH in ovary was downregulated significantly by ATR exposure and FSH and PRL in pituitary were upregulated. ATR exposure upregulated the level of P450scc, P450arom, 3β-HSD and 17β-HSD in ovary and downregulated ERβ expression in female quails. However, ATR did not change ERα expression in ovary. This study provides new insights regarding female productive toxicology of ATR exposure. Ovary and oviduct in sexually maturing females were target organs of ATR-induced developmental toxicity. We propose that ATR-induced developmental abnormality of ovary and oviduct is associated with disruption of gonadal hormone balance and HPO axis in female quails. - Highlights: • ATR triggers arrested development of ovarian and oviduct. • Ovary and oviduct are target organs of ATR-induced developmental toxicity. • Atrazine causes hormone adjustment disorder in female quails. • Atrazine upregulates steroidogenic factor and downregulates ERβ factor in ovary. • Atrazine disrupted the hypothalamo-pituitary-ovarian axis in famles. - Atrazine triggers arrested development of ovarian and oviduct via affected the steroidogenic and ERβ factor in ovary and disrupted the gonadal hormone balance and HPO axis in famles.

Full Text Available The difficulty of sex determination in most poultry species causes significant financial losses for poultry production as birds cannot be separated at early stages of growth for meat or egg production. Therefore it is important to determine bird’s sex with zoometric parameters. This study was carried out to determine the sex of Japanese quails with zoometric measurements, such as live weight, body length, chest depth and chest width. Eighty-eight male and female Japanese quail chicks were used individually for live weight, chest depth (mm, chest width (mm and body length (mm with using digital scaled balance and caliper for every week over a period of six weeks. The weekly collected data were applied to t test for estimating the sex discrimination. The Pearson’s correlation was applied for examining the interrelationship between sex and biometric traits. The results indicated that there was a significant positive correlation between live weight and body length beginning with the 2nd week. Therefore, zoometric measurement of these body traits is suitable for discriminating the sex of Japanese quails in early phase of life.

Investigated were effects of gas mixture with up to 3.0 kgs/cm2 of krypton on the embryonic development of domesticated Japanese quail (Coturnix coturnix japonica dom.). Results demonstrated absence of a serious krypton effect on Japanese quail embryos. Development of embryos proceeded in due course; morphometrically the experimental embryos were essentially similar to controls. It should be noted that despite exposure to acute hypoxic hypoxia during the initial 12 hours of development in the krypton-containing gas mixture, viability of quail embryos was high enough which can be ascribed to the krypton protective action. Besides, an additional experiment showed that krypton partial pressure of 5-5.5 kgs/cm2 produces the narcotic effect on adult Japanese quails.

Full Text Available Resumo O fenômeno do retorno dos dekasseguis - fluxo migratório de descendentes de japoneses ao Japão - ganhou visibilidade no Brasil, principalmente a partir da crise econômica mundial de 2008, quando aumentaram os retornos dos brasileiros. O objetivo da pesquisa foi investigar a experiência migratória dos filhos de dekasseguis que acompanharam seus pais no retorno ao Brasil. Para tanto, apresentamos um estudo de caso com uma menina de treze anos, nascida no Japão e que havia chegado recentemente ao Brasil com seus pais. Os resultados indicam que a infância vivida no Japão produz identificações profundas com a cultura japonesa. Algumas sequer falam o português, se consideram japonesas e se sentem estrangeiras no Brasil. As sensações de estranhamento e o desamparo predominam na experiência desses filhos de dekasseguis.

The distribution of 14 C-labelled chloramphenicol after oral and intravenous administration to egg laying Japanese quail was studied by whole-body autoradiography. In the liver, kidneys, gizzard, intestinal contents (bile) and oviduct, the 14 C-concentration was higher than that of the blood short time after injection and remained higher than the blood up to 4 days. From 4 hrs, the concentration of 14 C in the egg yolks was higher than that of the blood and from 24 hrs the radioactivity in the albumen of the eggs in the oviduct was also higher than that of the blood. The peak concentration in the egg yolk was found in the second egg laid 2-4 days after administration of 14 C-chloramphenicol. In the albumen the maximum concentration was found in the first laid egg 24-48 hrs after administration. In the egg yolks, about 30% of the radioactivity represented unchanged chloramphenicol up to 5 days after administration. It was also shown that about 5% of the injected 14 c-chloramphenicol was exhaled as 14 CO 2 during the first 12 hrs and about 37% of the dose was excreted in the combined faeces and urine during the same period of time.

The incorporation of 65 Zn into eggs was investigated after single or daily intraperitoneal administration to laying Japanese quails. After a single intraperitoneal administration, 65 Zn appeared first in the 2nd egg yolks and reached the highest level in the 3rd and 4th ones, followed by a gradual decrease. The cumulative amount of 65 Zn in the egg yolks over a period of 3 weeks accounted for about 40% of dose. After daily intraperitoneal administration, the 6th-9th egg's yolks contained the highest radioactivity of the eggs examined. Whole-body retention patterns were also observed in both of the experiments. (auth.)

COMPARATIVE EFFICACY OF DETOMIDINE AND DETOMIDINE - KETAMINE COCKTAIL IN QUAILS

Directory of Open Access Journals (Sweden)

U. F. Durrani, M. Ashraf and A. Khalid¹

2005-10-01

Full Text Available Twenty adult healthy quails (Coturnix coturnix were divided into two equal groups. One group was administered detomidine (2.4 mg/kg, I/M and other group was administered detomidine-ketamine cocktail (1.2 mg/kg + 30 mg/kg, I/M. Detomidine slowly and smoothly induced a light sedation accompanied by superficial analgesia, hypoventilation, hypothermia and bradycardia in all birds. Detomidine-ketamine cocktail rapidly and smoothly induced a deep anaesthesia accompanied by deep analgesia, hypoventilation, hypothermia and bradycardia and complete loss of all reflexes in all birds. In both groups, recovery from sedation and anaesthesia was smooth and of short duration. From this study it was concluded that for minor and least painful procedures in quails detomidine can be used alone, while for major and painful surgical procedures detomidine-ketamine combination should be preferred.

Full Text Available The main purpose of this study is to extend the microscopic investigations of the pecten oculi in the quail in order to add some information on the unresolved functional anatomy of this unique avian organ. The pecten oculi of the quail was studied by scanning electron microscopy. Eighteen- to-twenty two highly vascularised accordion-like folds were joined apically by a heavily pigmented bridge of tissue, which holds the pecten in a fanlike shape, widest at the base. The structure of the double layered limiting membrane was recorded. The presence of hyalocytes with macrophage-like appearance was illustrated. It is assumed that the pecten oculi of the quail resembles that of the chicken. Illustrated morphological features of this species may add information on the active physiological role of the pecten. But still, the functional significance of this organ is a matter of controversies.

Meat adulteration by substitution with lower value products and/or mislabeling involves economic, health, quality and socio-religious issues. Therefore, identification and traceability of meat species has become an important subject to detect possible fraudulent practices. In the present study the development of a high resolution melt (HRM) screening method for the identification of eight common meat species is reported. Samples from Bos taurus, Ovis aries, Sus scrofa domestica, Equus caballus, Oryctolagus cuniculus, Gallus gallus domesticus, Meleagris gallopavo and Coturnix coturnix were analyzed through the amplification of a 148 bp fragment from the cyt b gene with a universal primer pair in HRM analyses. Melting profiles from each species, as well as from several DNA mixtures of these species and blind samples, allowed a successful species differentiation. The results demonstrated that the HRM method here proposed is a fast, reliable, and low-cost screening technique. Copyright © 2017 Elsevier Ltd. All rights reserved.

Full Text Available O conceito de natureza tem sido caracterizado por uma série de dicotomias, como natureza externa/natureza interna e ambiente natural/corpo. De uma forma geral, a crítica ambientalista japonesa tem ignorado o lado direito desses dualismos - natureza interna e corpo. Este trabalho enfoca essas dimensões suprimidas através do exame do ecopoema de Hiromi Ito "Chitô [Tito]", retirado do livro Noro to Saniwa [Noro e Saniwa], que escreveu com Chizuko Ueno. Ao falar sobre natureza interna e corpo, o presente estudo ocupa-se especialmente da sexualidade e da queeridade. Hiromi Ito é perspectivada como uma ecopoeta queer, porque em "Chitô", ao questionar implicitamente a 'naturalidade' da heterossexualidade universal, ela problematiza as fronteiras entre heterossexualidade e homossexualidade, mostra sem inibições sua significação erótica retida do estágio anal pré-edipiano em suas explorações sexuais adultas, assim como uma utopia onanista sadomasoquista (SM reservada apenas a uma mulher, e trata os homens no poema como sendo meros corpos desmembrados e órgãos sexuais objetificados; mais ainda, sua queeridade encontra outras encorporações significantes em sua recusa de se deixar cair na armadilha de identidades sexuais ou sexualidades fixas. Nesse sentido, este trabalho ilumina as dimensões esquecidas das dicotomias natureza externa/ natureza interna e ambiente natural/corpo em "Chitô".The concept of nature has been characterized by a number of dichotomies such as outer nature/inner nature and the natural environment/body.

Full Text Available Tanto la arquitectura tradicional japonesa como los pensamientos del filósofo chino Lao zi son referencias fundamentales en la obra de Miguel Fisac, uno de los arquitectos españoles más destacados de la segunda mitad del siglo XX. A pesar de haber reconocido estas influencias en numerosas ocasiones, este hecho todavía no ha sido objeto de un estudio profundo. Sin embargo, el análisis de su obra y de su interés por Japón, a donde viajó varias veces, pone de relieve que la arquitectura española fue permeable a este influjo. El presente artículo aporta una visión más completa de la evolución de Fisac y ofrece un panorama histórico de su desarrollo durante las décadas de los años cuarenta y cincuenta, cuando concibió su personal concepto de la arquitectura tomando ideas de diferentes fuentes, entre las que Oriente se encuentra en un lugar principal. Además, se examina en detalle la repercusión que el contacto con la arquitectura japonesa tuvo en su producción.

Adult Japanese quail were administered 100 mg/kg chlorophenyl-labeled [ 14 C]fenvalerate, α-cyano-3-phenoxybenzyl 2-(4-chlorophenyl)isovalerate, for study of its distribution, elimination, and metabolism. Ninety percent of the administered dose was eliminated in the excreta within the first 24 h. In addition to fenvalerate, the following metabolites were present: benzeneacetic acid, 4-chloro-α-(1-methylethyl)-,cyano(3-phenoxy-4-hydroxyphenyl)methyl ester [4'-OH-fenvalerate]; benzeneacetic acid, 4-chloro-α-(1-methylethyl)-,(aminocarbonyl)(3-phenoxyphenyl)methyl ester [CONH 2 -fenvalerate]; 4-chloro-α-(1-methylethyl)benzeneacetic acid[Cl-V acid]; 4-chloro-α-(2-hydroxy-1-methylethyl)benzeneacetic acid[4-OH-Cl-V acid]. In time course studies radiocarbon peaked at 3 h (9μg/g) in the liver and gradually declined, while in the blood it peaked within 2 h and fell quickly to an equilibrium value of 1.5 μg/mL blood. In liver microsomal and isolated heptatocyte preparations of Japanese quail and rat, the following metabolites were identified: Cl-V acid, 4-OH-Cl-V acid, 4'-OH-fenvalerate, CONH 2 -fenvalerate. Oxidation was found to be the predominant route of degradation either pre- or post-hydrolysis of the parent compound. Rapid excretion, lesser absorption, and faster metabolism probably explain the lower toxicity of fenvalerate to birds compared to rats

Aflatoxins (AFs) contamination of foods and live-stock feeds is an ongoing problem. In this research, the amelioration of aflatoxicosis in Japanese quails was examined by the radiation processing of their contaminated-diets, as a physical detoxifying method. Diets contaminated with two different levels of AFB 1 (2 or 5 mg kg -1 diet) were subjected to 10, 20, or 30 kGy and fed to growing Japanese quails for 5 weeks. The physiological and biochemical responses were evaluated for irradiation ability to reduce the deleterious effects of 2 and 5 mg AFB 1 kg -1 diet. A total of 270 seven-day-old Japanese quail chicks were assigned to 2 factorial arrangements of nine treatments (level of toxin and radiation dose) each consisted of three replicates with 10 quails per pen. The significant adverse effect of AFB 1 on the food consumption, body-weight gain, food conversion ratio, mortality rate and internal organ weights, from the first week onwards, were determined. Radiation processing reduced concentration of AFB 1 in all experimental diets and significantly reduced the deleterious effects of AFB 1 on food consumption, body-weight gain, food conversion ratio, and the relative weights of most observed organs, as a function of radiation dose. Muscles, liver, kidneys and heart tissues were analyzed for aflatoxin (AF) residues. The residual level of AFB 1 was significantly higher in liver than in kidneys, muscles or heart. The level in the observed organs and the muscles was lower in those received irradiated diet at high 30 kGy. Plasma samples were tested for glucose, triglyceride, cholesterol, aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), urea and creatinine. They were significantly increased in AF treated groups in comparison with those received AF-containing diet and irradiated up to 30 kGy. Birds ate contaminated diet with both level of toxin were suffered from the lower level of total proteins, albumin, globulin, phosphorus and calcium. A function of radiation doses the physiological and biochemical responses in quails fed irradiated AF-containing diets were significantly improved, 30-kGy radiation dose was more effective in this respect.The current study showed that the use of radiation processing in AF-contaminated feed (2 or 5 mg kg -1 diet), significantly reduced negative effects of AF on toxicity. This effect can be related to the change in the AF molecule structure by the irradiation treatment into less toxic forms. AFs contamination in birds feed may cause economic losses by lowering body wt gain. Therefore, lower levels of AFs in the bird feeds should be required if all acceptable risk is to be avoided. Additionally, the risk of AFs in birds as a food appears to remain very low, although the levels of AFs in human food should be kept as low as possible to reduce the incidence of hepatic cancer

Full Text Available Threonine, like most amino acids, is traditionally noted for its role in protein synthesis. However, dietary threonine concentration required for the maximum performance of Japanese quails is yet to be determined, therefore, a study was conducted to determine the optimum threonine requirement of Japanese quail chicks in the tropical environment. A total of four hundred and fifty, two weeks old quail chicks (mixed sexes were randomly allocated to five dietary treatments (0.67, 0.81, 0.95, 1.08 and 1.22 % total threonine and replicated thrice in a completely randomized design (CRD. There were no significant differences (P>0.05 in average weight gain, average feed intake, feed conversion ratio and age at first lay of quails fed the dietary treatments. Weight of first egg laid was significantly (P0.05 similar for all treatments. There were significant differences (P0.05. It was concluded that the performance of birds were not influenced by the dietary treatments up to the highest dietary level of threonine studied (1.22%. Therefore, it is possible that the optimum dietary level of threonine may be above 1.22 %. Further studies will be necessary to establish higher doses of dietary threonine requirement of Japanese quails reared under tropical climatic environment.

Castle, Marc D.; Christensen, Beth A.; Rocke, Tonie E.

1988-01-01

One hundred twenty-three of 300 blood samples (41%) taken from Rio Grande wild turkeys (Meleagris gallopavo intermedia) from three locations in southern Texas (Welder Wildlife Refuge, Chaparrosa Ranch, and Campo Alegre Ranch) and subinoculated into domestic broad-breasted white turkey poults were positive for a Plasmodium (Novyella) sp. Analysis of blood films from 350 turkeys revealed Haemoproteus meleagridis in 76% of the birds. A significantly greater mean parasite intensity was observed in birds from Welder Wildlife Refuge. Birds from the Campo Alegre Ranch exhibited a significantly higher prevalence of H. meleagridis than birds from Chaparrosa. The Plasmodium sp. was infective for canaries (Serinus canaria), bobwhites (Colinus virginianus), and ring-necked pheasants (Phasianus colchicus), but would not produce infection in white leghorn chickens (Gallus gallus) or Coturnix quail (Coturnix coturnix). Attempts to infect Culex tarsalis and C. pipiens pipiens were unsuccessful. Asexual erythrocytic synchrony was not observed when blood-induced infections were monitored in two domestic turkey poults every 4 hr for 72 hr. Exoerythrocytic stages were not found upon examination of impression smears and tissue samples taken from brain, liver, spleen, kidney, lung, and bone marrow. The Plasmodium sp. is most similar morphologically to three species in the subgenus Novyella, P. hexamerium, P. vaughani, and P. kempi. The most striking similarities are to P. hexamerium, and involve mean merozoite number, erythrocytic schizont location, and vertebrate host susceptibility. It differs from P. vaughani in being able to infect turkeys and in type of parasitized erythrocytes. Differences to P. kempi include mean merozoite number, and ability to infect pheasants, and its inability to develop inC. pipiens and C. tarsalis.

The study was conducted to evaluate the feed efficiency of quail diets containing different concentrations of metabolizable energy (ME) and crude protein (CP) with constant ratio and supplemented with methionine. Four hundred laying quails (Coturnix coturnix japonica) were randomly assigned to four experimental diets in a 2×2 factorial arrangement. Each dietary treatment used 5 replicates of 20 quails. Two basal diets were formulated to contain 2,800 kcal kg-1 ME and 18.7% CP (High ME-CP) and 2,600 kcal kg-1 ME and 17.3% CP (Low ME-CP). Each basal diet was supplemented with 0 and 0.12% methionine. The High ME-CP diets generated lower feed consumption but higher egg mass and feed efficiency (Pprotein efficiency ratio (PHigh ME-CP supplemented with methionine resulted the highest feed efficiency followed by the Low ME-CP supplemented with methionine, while both High ME-CP and Low ME-CP without methionine supplementation resulted the lowest feed efficiency (PHigh ME-CP supplemented with 0.12% methionine provided benefit to improve the feed efficiency in laying quails.

Processos de consumo cultural e midiático: imagem dos 'Otakus', do Japão ao mundo

Directory of Open Access Journals (Sweden)

Yuji Gushiken

Full Text Available Na perspectiva teórica da Comunicação como cultura, este artigo tem como tema central a dimensão comunicacional dos processos culturais na contemporaneidade. O objetivo é narrar e discutir a imagem difundida do grupo social denominado de Otaku, carregada de ambivalência a partir de sua origem no Japão e sua inserção no imaginário midiatizado em escala mundial. No Japão, o imaginário Otaku carrega a conotação negativa de indivíduos fanáticos pelo consumo de produtos da cultura pop, de pouca tendência para a vida social e associados a comportamentos psicopatológicos e criminosos. Em países da Ásia e no Brasil, o termo Otaku passou a designar os fãs de cultura pop japonesa, mas com características de uma juventude em busca de troca de informações e de novos modos de sociabilidade na vida urbana. Na cultura mundializada, conclui-se que o imaginário Otaku se transforma na medida em que segmentos da juventude em diferentes países, a partir de suas matrizes culturais, reinventam processos de consumo de produtos da cultura pop japonesa e lhes atribuem distintos sentidos.

Carbon-14-ochratoxin A distribution in the Japanese quail (Coturnix coturnix japonica) monitored by whole body autoradiography

International Nuclear Information System (INIS)

Fuchs, R.; Appelgren, L.E.; Hagelberg, S.; Hult, K.

1988-01-01

Tissue distribution of the nephrotoxic mycotoxin ochratoxin A was characterized in laying Japanese quail by whole body autoradiography and scintillation counting using 14 C-labelled toxin. Periodically for 8 days after one intravenous injection of 14 microCi/bird, corresponding to 70 ng/g body weight, birds were killed, frozen, and sagittal sections of the whole body were placed on X-ray film. In general, the ochratoxin disappeared from the avian body rapidly. Specific retention of radioactivity was seen as a ring-like distribution in yolks and growing follicles. After sectioning, organs and intestinal contents were removed from carcasses in a frozen condition, homogenized, extracted, chromatographed, and the radioactivity in fractions was measured by scintillation spectroscopy. High concentrations of ochratoxin A were found in gastric intestinal contents, probably originating from toxin excreted in the bile

Full Text Available Aim: Genotype VII Newcastle disease virus (NDV is the most predominant NDV strains that circulating in Malaysia; thus, this study was aimed to determine the susceptibility of Japanese quails toward genotype VII NDV. Clinical signs, gross pathological lesions of organs, positive detection of virus in organs and cloacal swabs, as well as the expression of the antibody titer, were used as parameters to assess the susceptibility of Japanese quails following infection of genotype VII NDV. Materials and Methods: About 20 quails were divided into three groups (n=8 for Groups A and B; n=4 for the control group. The quails in the Groups A and B were infected via intraocular route with 0.03 ml of 103.5 ELD50 and 107.0 ELD50 of NDV strain IBS 002, respectively, while the control group received 1x phosphate-buffered saline. Cloacal swabs and necropsy were taken on day 7 post-infection for all quails were subjected to one-step reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR for detection of virus and examination for gross pathological lesion, respectively. Blood serums of infected quails were taken on day 10, 14, and 21 post-day infections and were subjected for hemagglutination inhibition (HI assay. Results: Depression and ruffled feathers, trachea rales, leg paralysis, and torticollis were shown in some of the quails in both infected groups. Based on statistical analysis, there was no significant difference (p>0.05 in clinical signs between the infected groups. The results for RT-qPCR were found to be negative for all groups, and no gross pathological lesions of organs observed for quails in both infected groups. Trachea, proventriculus, and cecal tonsil were taken for the detection of NDV by RT-qPCR, and some of the organ samples showed positive detection of virus in both infected groups. HI assay showed an increase in mean titers of antibody across time and between infected groups. Conclusion: In summary, Japanese quails are susceptible to genotype VII NDV based on parameters assessed.

A PCR assay was developed for the identification of meats and commercial meat products from quail (Coturnix coturnix), pheasant (Phasianus colchicus), partridge (Alectoris spp.), guinea fowl (Numida meleagris), pigeon (Columba spp.), Eurasian woodcock (Scolopax rusticola), and song thrush (Turdus philomelos) based on oligonucleotide primers targeting specific sequences from the mitochondrial D-loop region. The primers designed generated specific fragments of 96, 100, 104, 106, 147, 127, and 154 bp in length for quail, pheasant, partridge, guinea fowl, pigeon, Eurasian woodcock, and song thrush tissues, respectively. The specificity of each primer pair was tested against DNA from various game and domestic species. In this work, satisfactory amplification was accomplished in the analysis of experimentally pasteurized (72 degrees C for 30 min) and sterilized (121 degrees C for 20 min) meats, as well as in commercial meat products from the target species. The technique was also applied to raw and sterilized muscular binary mixtures, with a detection limit of 0.1% (wt/wt) for each of the targeted species. The proposed PCR assay represents a rapid and straightforward method for the detection of possible mislabeling in game bird meat products.

Ratriyanto, A.; Indreswari, R.; Dewanti, R.; Wahyuningsih, S.

2018-03-01

This experiment investigated the effect of betaine supplementation to low methionine diet on egg quality of quails. A total of 340 laying quails (Coturnix coturnix japonica) was divided into 4 dietary treatments with 5 replicates of 17 quails each. The experiment was assigned in a completely randomized design. The four dietary treatments were the low methionine diet (0.3% methionine) without betaine supplementation and the low methionine diet supplemented with 0.07, 0.14, and 0.21% betaine. The experimental diets were applied for 8 weeks and the egg quality traits were measured at the age of 16 and 20 weeks. The data were subjected to analysis of variance, and when the treatment indicated significant effect, it was continued to orthogonal polynomial test to determine the optimum level of betaine. Increasing dietary levels of betaine increased the fat content of the egg with the linear regression of y = 11.0949 + 4.1914x (R2 = 0.18). However, supplementation of betaine did not affect protein content, yolk, albumen, and eggshell percentage. It can be concluded that betaine supplementation up to 0.21% to low methionine diet only had little effect in improving the quality traits of quail eggs.

Genetic changes were studied in economically significant species of birds and the impact of gamma radiation on their organisms in general. The impact is dealt with of small, medium and high doses of radiation on gonadal cells in vivo and in vitro and on fertilized eggs, and the total impact on the organism. During the irradiation of embryos toxic effects were unambiguously found for exposures to more than 100 R. The embryo was most sensitive between the 2nd and 4th day of development. No cytotoxic effect of radiation was observed in sperms exposed in vitro to less than 10,000 R. Irradiation of gonads affected the reproduction capacity of male birds substantially more than that of female birds. (M.D.)

Detecting slow introgression of invasive alleles in an extensively restocked game bird

Directory of Open Access Journals (Sweden)

Ines eSanchez-Donoso

2014-04-01

Full Text Available Interbreeding of two species in the wild implies introgression of alleles from one species into the other only when admixed individuals survive and successfully backcross with the parental species. Consequently, estimating the proportion of first generation hybrids in a population may not inform about the evolutionary impact of hybridization. Samples obtained over a long time span may offer a more accurate view of the spreading of introgressed alleles in a species’ gene pool. Common quail (Coturnix coturnix populations in Europe have been restocked extensively with farm quails of hybrid origin (crosses with Japanese quails, C. japonica. We genetically monitored a common quail population over 15 years to investigate whether genetic introgression is occurring and used simulations to investigate our power to detect it. Our results revealed that some introgression has occurred, but we did not observe a significant increase over time in the proportion of admixed individuals. However, simulations showed that the degree of admixture may be larger than anticipated due to the limited power of analyses over a short time span, and that observed data was compatible with a low rate of introgression, probably resulting from reduced fitness of admixed individuals. Simulations predicted this could result in extensive admixture in the near future.

The purpose of this study was to know the production performance and economic analysis in quail which use probiotic supplementation to alternate antibiotic growth promoter (AGP) to feed consumption, water consumption, egg production, egg mass, feed conversion, and feed efficiency. About 240 quails ( Coturnix coturnix japonica) at 14 weeks of age were completely randomized into four treatments, each treatment consisted of six replications and each replication consisted by 10 heads. The treatment was T0 (organic feed without AGP and without probiotic), T1 (organic feed + 0.001% AGP), T2 (organic feed + 0.005% probiotic in feed), and T3 (organic feed + 0.005% probiotic in drinking water). The probiotic consist of 1.2×10 5 CFU/g of Lactobacillus casei and Lactobacillus rhamnosus . The results showed that the probiotic supplementation both in feed and water give a significant impact to feed consumption, water intake, feed conversion, feed efficiency, and quail day production, but no statistical difference of egg mass. The T3 also show the most profitable business analysis, which has the best result in income, profit, break-even point, return cost ratio, benefit-cost ratio, and return on investment. It can be concluded that giving 0.005% probiotic in drinking water to get the best egg production and profit.

Full Text Available The objective of this study was to determine and compare the levels of amino acids (AAs in breast and thigh muscles of six species of feathered game of the same age. The experiment involved the following species: wild turkey (Meleagris gallopavo, guinea fowl (Numida meleagris, chukar partridge (Alectoris chucar, Japanese quail (Coturnix coturnix japonica, common pheasant (Phasianus colchicus and grey partridge (Perdix perdix. The highest content of AAs was found in the chukar partridge (breast: 815.7 ± 47.71 g/kg; thigh: 771.4 ± 107.0 g/kg, on a dry matter basis, the lowest levels of AAs were found in Japanese quail (breast: 734.2 ± 45.07 g/kg and grey partridge (thigh: 614.9 ± 49.66 g/kg. In all examined species, the level of histidine in breast muscles differed (P ≤ 0.01 from that in thigh muscles. In all investigated species, the levels of essential AAs in breast muscles were higher (P ≤ 0.01 than those in thigh muscles, whereas the levels of non-essential AAs in breast muscles were lower (P ≤ 0.01 than those in thigh muscles. Breast muscles are therefore more valuable than thigh muscles because of the content of essential AAs.

The optic gland, which is analogous to the anterior pituitary in the context of gonadal maturation, is found on the upper posterior edge of the optic tract of the octopus Octopus vulgaris. In mature octopus, the optic glands enlarge and secrete a gonadotrophic hormone. A peptide with structural features similar to that of vertebrate gonadotrophin-releasing hormone (GnRH) was isolated from the brain of octopus and was named oct-GnRH. Oct-GnRH showed luteinising hormone-releasing activity in the anterior pituitary cells of the Japanese quail Coturnix coturnix. Oct-GnRH immunoreactive signals were observed in the glandular cells of the mature optic gland. Oct-GnRH stimulated the synthesis and release of sex steroids from the ovary and testis, and elicited contractions of the oviduct. Oct-GnRH receptor was expressed in the gonads and accessory organs, such as the oviduct and oviducal gland. These results suggest that oct-GnRH induces the gonadal maturation and oviposition by regulating sex steroidogenesis and a series of egg-laying behaviours via the oct-GnRH receptor. The distribution and expression of oct-GnRH in the central and peripheral nervous systems suggest that oct-GnRH acts as a multifunctional modulatory factor in feeding, memory processing, sensory, movement and autonomic functions.

Full Text Available A study was conducted to determine the effect of foam extract on sperm motility in the male Japanese quail (Coturnix coturnix japonica. Adult male quails (<12 weeks of heavy body weight strain were housed in individual cages and divided into 5 groups according to the size of their cloacal glands. The data indicated that the size of the cloacal gland was positively correlated with the frequency of foam secretion and total foam production. One gram of freshly collected clean foam was mixed with 1.0 mL of normal saline and homogenized for 10 minutes. After centrifugation at 35 000 rpm, the supernatant was used as 100% foam extract. The extract was diluted to 1:40, 1:20, 1:10, and 1:4 with normal saline to produce 2.5, 5.0, 10, and 25% foam extracts, respectively. 5% foam extract enhanced sperm survival at room temperature (30°–35°C for 2 to 3 hrs, whereas higher concentrations (10% and above suppressed sperm motility. From this study, it may be concluded that foam secretion and quantity of foam are directly proportional to the size of the cloacal gland and that the foam enhances and prolongs sperm motility, in vitro at an optimum concentration of 5%.

In the present study we detailed the distribution of GFAP-immunopositive structures within the central nervous system of the Japanese quail. Different fixation and embedding procedures were applied. The best results were obtained on frozen cryostatic sections from freshly dissected brains subsequently fixed by a short immersion in cold acetone. Immunopositive structures were observed both with immunofluorescence, and with immunoperoxidase methods. Immunoreactive cell bodies and processes were observed within the whole central nervous system, and different cell types can be identified on the basis of their topographical location and morphology. A first class of astrocytes is composed of intensely stained unipolar cells lining the inner surface of the pia mater and the large blood vessels. A second type is represented by multipolar astrocytes of variable size, provided with an irregular cell body. The last type is represented by similar elements, showing an immunonegative cell body, that can be identified only by the presence of converging processes. These three types of cells, and several isolated processes, show a differential distribution within the quail central nervous system, both in the grey and in the white matter. Present results suggest that GFAP may represent a good marker for at least part of the astroglial population in quail.

Avian require comfortable temperatures for optimal development and heat stress is a high concern in warm weather countries. We aimed to assess the dynamics of immunoendocrine and biochemical variables responses of birds exposed to a heat stressor applied during daylight hours, during the chronic stress and the recovery periods. We hypothesize that variables involved in the birds response will be differentially and gradually modified during those periods. Female quail (n = 210) were housed in six rearing boxes. At 29 days of age, the temperature in three boxes was increased from 24 to 34 °C during the light period throughout the nine days (Stress Treatment). The other three boxes remained at 24 °C and were used as controls. The subsequent 12 days were considered as recovery period. Different sets of 12 birds/treatment were blood-sampled at 29 (basal), 32, 35, 38 (stress), 41, 44, 47, and 50 (recovery) days of age, respectively. Immunoendocrine (corticosterone, lymphoproliferation, heterophil/lymphocyte ratio (H/L), and antibody response) and biochemical (glucose, total proteins, globulins, and albumin) variables were assessed. During stress, progressive corticosterone and H/L increments, and antibody titers and lymphoproliferation decreases were detected. No clear pattern of changes was found in biochemical variables. During recovery, while corticosterone and lymphoproliferation had recovered three days after the stressor ended, H/L and antibody responses required respectively nine and 12 days to recover to their basal levels, respectively. Findings suggest that immunity is already threatened when heat stress is sustained for three or more days. However, the system appears resilient, needing six to 12 days to recover to their basal responses.

Full Text Available H9N2 avian influenza A viruses are endemic in poultry of many Eurasian countries and have caused repeated human infections in Asia since 1998. It has been also reported that H9N2 can cause high mortality in commercial broiler farms in Iran previously. However there was no report of H9N2 outbreak in any other species. In order to evaluate the pathogenicity of H9N2 virus in Japanese quail, 145 Japanese quail were randomly divided into 5 separate groups (116 quails in the treatment and 29 quails in the control groups. The experimental groups infected via oral rout, eye drop, intramuscular injection and spray method at the age of 32 days with 106.5 EID50/bird. The virus A/chicken/Iran/ZMT-101/98(H9N2 was kindly provided obtained from Razi vaccine& serum institute with EID50=108. The blood samples were experimented the day before use to show freedom from antibodies to influenza A and more specifically, the H9 subtype. The clinical signs and antibody titer of the infected chicks were also monitored. Five birds of each group were bled at 10 and 20 days post infection (DPI, and 20 birds of each group at 30 DPI were bled. The immune response to infection was measured by Haemmaglutination Inhibition (HI test using the H9N2 virus as antigen. Feed & water consumption were recorded on daily bases before and after inoculation. Body weight of each group was also recorded on weekly bases before and after inoculation. During the current study clinical signs such as sneezing, gasping, depression observed in challenged groups followed by decreasing in laying (1-17%. High HI antibody titers of AIV subtype H9 was seen in 10 DPI. The quails exhibited no decrease in food and water consumption and all quails were growing well and did not show any abnormality.

Full Text Available Objective: To investigate the effect of wild black mustard seed meal on thyroid hormones (thyroxine and thyroid-stimulating hormone in Japanese quails and also study the ability of FeSO4 to alleviate the possible negative effect of mustard meal on thyroid hormones in these birds for the first time. Methods: The experimental procedure was undertaken on 28 quails which were randomly assigned to a control and 6 test groups with 4 quails in each group for 28 days, during which the control group received basic diet with no mustard meal whereas the test groups (No. 2, 3 and 4 received mustard meal (5%, 10% and 15%, respectively and test groups (No. 5, 6 and 7 received FeSO4 (1%-treated mustard meal (5%, 10% and 15%, respectively on the basic of basic diet. Results: The group fed on 15% non-treated mustard seed meal had the least thyroxine level and its level backed to normal in group fed on 15% FeSO4-treated mustard seed meal although this group had the highest alanine transaminase and aspartate transaminase levels. Conclusions: We concluded that up to 10% FeSO4 mustard seed meal could be incorporated in the quail diet successfully with the least damage to thyroids and livers, but further investigations on these birds are still needed to confirm this hypothesis.

Eight species representing 8 genera of gallinaceous birds were used: Alectoris graeca; Colinus virginianus; Coturnix coturnix; Gallus gallus; Meleagris gallopavo; Numidia meleagris; Pavo cristatus; Phasianus colchicus. Three week-old birds were dosed with sporulated oocysts of Eimeria tenella Beltsville strain. At 4, 24, 48, 72, 96, 120 and 144, and 168 hr after inoculation, 1-3 infected birds and uninoculated controls of each species were killed by cardiac exsanguination. Pieces of intestines were fixed and examined for stages of E. tenella as stained paraffin sections or indirect fluorescent antibody preparations. Oocyst counts were made in droppings collected for the first 6 days of the patent period. Sporozoites were found in the lamina propria of some birds of 5 species at 4 hr postinoculation, but no stages were found thereafter except in the breeds of G. gallus and A. gracea. At 144 and 168 hr postinoculation, a few macrogametes were found in the ceca of 2 A. gracea, but no oocysts were found in the feces. No statistical difference was found between the number of oocysts produced/bird in the breeds of G. gallus examined. It is evident from these observations the E. tenella did not complete its life cycle in several close phylogenetic relatives of G. gallus, even though in other studies this parasite was found to complete its life cycle in cell cultures derived from the same birds.

To define the process of karyotypic evolution in the Galliformes on a molecular basis, we conducted genome-wide comparative chromosome painting for eight species, i.e. silver pheasant (Lophura nycthemera), Lady Amherst's pheasant (Chrysolophus amherstiae), ring-necked pheasant (Phasianus colchicus), turkey (Meleagris gallopavo), Western capercaillie (Tetrao urogallus), Chinese bamboo-partridge (Bambusicola thoracica) and common peafowl (Pavo cristatus) of the Phasianidae, and plain chachalaca (Ortalis vetula) of the Cracidae, with chicken DNA probes of chromosomes 1-9 and Z. Including our previous data from five other species, chicken (Gallus gallus), Japanese quail (Coturnix japonica) and blue-breasted quail (Coturnix chinensis) of the Phasianidae, guinea fowl (Numida meleagris) of the Numididae and California quail (Callipepla californica) of the Odontophoridae, we represented the evolutionary changes of karyotypes in the 13 species of the Galliformes. In addition, we compared the cytogenetic data with the molecular phylogeny of the 13 species constructed with the nucleotide sequences of the mitochondrial cytochrome b gene, and discussed the process of karyotypic evolution in the Galliformes. Comparative chromosome painting confirmed the previous data on chromosome rearrangements obtained by G-banding analysis, and identified several novel chromosome rearrangements. The process of the evolutionary changes of macrochromosomes in the 13 species was in good accordance with the molecular phylogeny, and the ancestral karyotype of the Galliformes is represented.

The experimental work aimed at the quantitative ultrastructure of the myocardial cells of the Japanese quail Coturnix coturnix japonica during hypergravitation, hypodynamism and space flight in a Soviet satellite. For the determination of quantitative changes of the myocardial ultrastructure a morphometrical method was used with parameters like the number of mitochondria, average mitochondrial size, relative mitochondrial volume, deficiency of cristae and relative volume of myofibrils. The quails were observed in 3 groups. The absolute control consisted of quails living in normal Earth conditions, in the laboratory group the quails were exposed to conditions of hypergravitation and hypodynamism in a specially constructed centrifuge, and in the flying group the quails were exposed to space flight in a Soviet orbital station MIR. In the group of absolute controls no pathological changes of the myocardial ultrastructure were found. In the flying group there were no significant changes, with the exception of decreased relative volume of myofibrils, which however agrees with the findings on symptoms corresponding to human and animal heart weakness during space flights. In the laboratory group, pathological changes were observed in each of the fractions. The most significant pathological findings were found in the group controls in the center and in hypergravitation combined with hypodynamism. It can be concluded that the laboratories can simulate conditions induced by the start and flight of space ships. (Fig. 2, Ref, 8.)

Apart from clinical observations, experiments were evaluated in terms of histopathology, immunofluorescence, serology and recovery of virus. Only peafowl and pheasants were found to be susceptible, pheasants responding more strongly than chickens to ocular vaccination and intratracheal inoculation. The other species were found to be refractory.

Full Text Available No urbanismo ocidental sempre tiveram relevância o emprego da perspectiva e o destaque das praças, monumentos e ruas. Porém essa noção de cidade como estrutura hierarquizada e linear é a antítese da idéia espacial urbana nipônica. O espaço sempre reflete os princípios de uma cultura. Os japoneses conseguiram, ao aprenderem a cultura e a técnica de outros povos, preservar suas próprias tradições. A nossa enorme dificuldade de percepção e leitura dos espaços orientais é explicada pelo desconhecimento. Para superar esse obstáculo é necessário o emprego de uma gramática espacial não-linear. Para entender o sistema espacial do Japão é preciso pesquisar as complexas relações entre o mundo visível e invisível. Esses princípios que definem as características do espaço são: ku - vazio, oku - profundidade e ma - intervalo. Eles criam uma ordem mais orgânica, natural, com estrutura aberta e movimentada, comum à expansão das típicas cidades japonesas. Finalmente, o objetivo deste artigo é a compreensão desses conceitos. Hoje, diante das dificuldades no Ocidente para conceber um ambiente urbano adequado, é muito apropriada a busca de uma nova visão, como a japonesa, aqui sinteticamente apresentada.

Foram utilizadas 200 codornas japonesas fêmeas com 251 dias de idade, peso médio de 187,2 ± 6,0 g e taxa de produção de ovos de 84,8%, distribuídas em delineamento inteiramente casualizado com quatro dietas experimentais e cinco repetições de dez aves por unidade experimental. As dietas experimentais consistiram de uma ração basal à base de milho e farelo de soja, formulada para atender às exigências nutricionais das codornas e às recomendações da matriz da fitase, suplementada com 0, 200, 400 ou 600 unidades de fitase (uf/kg. Utilizando-se o método de coleta total de excretas, foram determinados os valores de matéria seca ingerida, matéria seca excretada, energia metabolizável aparente (EMA, energia metabolizável aparente corrigida pela retenção de nitrogênio (EMAn e os coeficientes de metabolizabilidade da energia corrigida ou não pelo balanço de nitrogênio. Foi calculada também a quantidade de fósforo, cálcio e nitrogênio retido por ave/dia. De maneira geral, houve melhora no aproveitamento da energia das rações com a suplementação de fitase. Os níveis de 195 e 186 uf/kg resultaram em maior aproveitamento da EMA e EMAn. Não houve diferença na retenção de fósforo e cálcio. O nível de 600 (uf/kg promove menor excreção de nitrogênio, porém o de 368 uF/kg é suficiente para máxima retenção de nitrogênio pelas codornas.This experiment was conducted to evaluate the effect of phytase addition on the use of feeding ingredients for laying quails.

Graded levels of phytic acid (PA) were fed to day-old Japanese quail (Coturnix coturnix japonica) for 7 d to establish responses for evaluating effects of inositol tri-, tetra-, and pentaphosphates. Sodium phytate was added to supply 1.4, 2.8, 5.5, 8.4, 11.0, and 13.8 g PA/kg adequate casein-gelatin diet containing 20 mg Zn/kg. Eleven g phytic acid approximates that in diets containing defatted soy flour as the protein source. PA:Zn molar ratios were 7, 14, 27, 41, 54, and 68. The effects and graded response ranges (g PA/kg diet) were as follows: decreased body weight, 2.8-13.8; defective feathering, 1.4-5.5; decreased tibia Zn, 1.4-5.5; decreased tibia ash, 1.4-13.8; and decreased pancreas Zn, 1.4-5.5. The lowest level of PA produced marked decreases in tibia and pancreas Zn; thus the PA ranges can be extended to even lower levels. The effects of PA were reproducible between experiments and the mean values were reproducible except for tibia ash and liver Mn, which varied somewhat. There were no effects of PA on liver Zn and Mg, or on pancreas Fe and Mg; the effects on liver Fe and Cu, and tibia Fe and Mg were small and inconsistent. The responses to PA and the dose ranges provide a realistic basis for assessing the biological effects of other inositol phosphates that can be formed during food processing

This study was designed to evaluate the protective effects of Arctium lappa L. root extracts (AREs) from different extraction methods (aqueous, ethanol, chloroform and flavone) on atherosclerosis. Quails (Coturnix coturnix) were subjected to high fat diet, with or without one of the four different AREs or positive control simvastatin. Blood samples were collected before treatment, after 4.5 weeks or ten weeks to assess lipid profile (Levels of total cholesterol (TC), Triacylglycerol (TG), low-density lipoprotein (LDL) and high-density lipoprotein (HDL)). After ten weeks, the serum levels of nitric oxide (NO) as well as antioxidant and pro-oxidative status (Levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), nicotinamide adenine dinucleotide phosphate (NADPH) and glutathione peroxidase (GSH-Px)) were measured. Furthermore, aortas were collected after ten weeks treatment, aorta lipid contents (TC, TG and LDL) were assessed, and histology was used to confirm atherosclerotic changes. The results indicated that high fat diet significantly deteriorated lipid profile and antioxidant status in quail serum, while all the extracts significantly reverted the changes similar to simvastatin. Aorta lipid profile assessment revealed similar results. Histology on aortas from quails treated for ten weeks confirmed atherosclerotic changes in high fat diet group, while the extracts significantly alleviated the atherosclerotic changes similar to simvastatin. Among the different extracts, flavones fraction exerted best protective effects. Our data suggest that the protective effects of AREs were medicated via hypolipidemic and anti-oxidant effects. Underlying molecular mechanisms are under investigation.

Full Text Available The objective of this study was to estimate the nutrient requirements of digestible threonine for meat-type quails (Coturnix coturnix sp in the growth phase. A total of 1350 not sexed meat-type quails were distributed in a completely randomized design with six threonine levels (10.80, 11.50, 12.20, 12.90, 13.60 and 14.30 g/kg as fed, five replications and 45 quails per experimental unit, from 1 to 14 days of age. The threonine levels in the diet had a quadratic effect on body weight, feed intake and weight gain. Estimates for highest body weight (79.41 g, feed intake (128.96 g/bird and weight gain (70.73 g were observed with diets containing 12.60 g/kg of digestible threonine. According to the LRP model, the threonine intake was estimated at 13.40 g/kg of digestible threonine. Protein deposition rate and energy retained in the carcass showed quadratic effect, with estimated digestible threonine levels of 11.80 and 12.00 g/kg in the diet for maximum protein deposition rate (2.00 g/bird and retained energy in the carcass (15.88 kcal/g, respectively. There was a linear effect on feed cost per kg of live weight gain as threonine levels were increased. Nutritional requirement of digestible threonine for meat-type quails for maximum growth is 12.60 g/kg, corresponding to a digestible threonine:digestible lysine ratio of 67.02.

By counting and measuring the major ova of breeding birds at autopsy and combining these data with time intervals between ovipositions, rough estimates have been made of the time required to form yolk in some non-captive birds (King 1973). Direct studies have been made in domestic fowl (Gallus gallus var. domesticus; Gilbert 1972), turkeys (Meleagris galloparvo; Bacon and Cherms 1968), and Common quail (Coturnix coturnix; Bacon and Koontz 1971), by feeding the birds a capsule containing dye each day, and counting dye rings in the yolks after the eggs have been hardcooked. Recently developed methods of fixing and staining eggs have revealed differences in yolk deposited during day and night, thus permitting another estimation of the number of days during which yolk was deposited, and without direct contact with the female (Grau 1976). In eggs from chickens and quail that have been fed dyes, yolk that stained darkly with dichromate was shown to be deposited during the active daytime feeding periods, while pale-staining yolk was deposited during the night. Thus, pairs of light and dark rings, which together take a day to be deposited, may be counted to estimate time of yolk formation.In the present study we have applied the yolk ring method of estimating the number of days during which the bulk of the yolk is deposited around the central white core (Grau 1976) to the eggs of some shorebirds, gulls, terns and alcids.

Calorimetric analysis revealed significant (P ≤ 0.05 and highly significant (P ≤ 0.01 differences between individual species in the content of energy in breast and thigh muscles. The highest content of energy (recalculated to dry matter was found in breast muscles from wild turkey (24.75 MJ·kg-1 and Japanese quail (24.57 MJ·kg-1 whereas the highest content of energy (recalculated to dry matter in thigh muscles was found in Japanese quail and grey partridge. Highly significant (P ≤ 0.01 differences in the energy content were also found between breast and thigh muscles in all studied game species except for wild turkey. Differences in the content of energy in muscles between individual species occur mainly due to different contents of fat in muscles. This is also confirmed by high correlation coefficients between the content of energy and the content of fat in breast (r = 0.912 and thigh muscles (r = 0.878. Our study provides more specific data on the amount of energy in muscles of major species of feathered game reared in Europe and significantly extends current knowledge in this field.

This experiment was carried out to determine the effects of the usage of dried brewing yeast in quail diets on laying performance, egg traits and blood parameters. A total of 240 Japanese quails (Coturnix coturnix japonica) aged 10 weeks were randomly allocated into one control group and three treatment groups. Each group was divided into five replicates as subgroups, comprising 12 quails each. Dried brewing yeast (Saccharomyces cerevisiae) was used at the levels of 1.5%, 3.0% and 4.5% in the diets of the first, second and third treatment groups, respectively. Soyabean meal was replaced with dried brewing yeast. The diets were formulated to be isocaloric and isonitrogenous. The experimental period lasted 18 weeks. Dietary treatments did not significantly affect body weight, daily feed intake, daily protein intake, egg production, egg weight, feed efficiency, mortality, egg shell thickness, egg albumen index, egg yolk index, egg Haugh unit, the percentages of egg shell, albumen and yolk, excreta moisture and small intestinal pH. Inclusion of 3% and 4.5% dried brewing yeast in diets reduced egg yolk cholesterol concentration as mg per yolk and mg per g yolk (P brewing yeast was significantly lower (P brewing yeast resulted in significant increases (P brewing yeast. It is concluded that dried brewing yeast can be used up to 4.5% in the diets of laying quails without adverse effects on the measured parameters.

Full Text Available ABSTRACT The objective of this study was to determine the effect of dietary symbiotic supplementation on the growth performance and duodenum histological parameters of quail reared in different flooring systems. A total of 160 mixed-sex healthy quail (47±0.32 g aged 14 days were used in a 2 × 2 factorial experimental design with four replicates, each including five males and five females. Two flooring systems (wire floor as control and wood shavings bedding and two dietary treatments (symbiotic supplementation and no supplementation were tested. Birds were transferred to four-tier cages for the trial. Each kilogram of the commercial diet included 224 g crude protein and 3,080 kcal metabolizable energy. The experiment lasted 21 days. Daily weight gain and gastrointestinal tract weight were statistically higher in the wood shavings and wood shavings + symbiotic-supplemented groups than in control group. Villi length was higher in the wood shavings + symbiotic and symbiotic-supplemented groups than in control and wood shavings groups. The wood shavings groups had longer villi than control group. Villi width was higher in wood shaving + symbiotic-supplemented groups compared with the other treatment groups. The litter system of wood shavings and symbiotic supplementation provide better growth performance to quail by developing their duodenum histomorphological parameters and digestive tract.

2012-05-01

Full Text Available Este artigo busca analisar o papel da religiosidade e o impacto da rede de apoio social na vida dos migrantes brasileiros no Japão. Apesar dos brasileiros estarem no Japão por aproximadamente duas décadas, estes não se integraram à sociedade japonesa. Este estado de alienação social na sociedade japonesa exerce um efeito negativo sobre nas condições de saúde dos migrantes, tornando-os vulneráveis a distúrbios físicos e mentais. Eles se sentem encurralados, pois mesmo que busquem ajuda de profissionais da saúde a falta de fluência na língua japonesa os impedem de se expressarem corretamente. Neste contexto os migrantes buscam apoio e solidariedade entre seus compatriotas e nos grupos religiosos. Este estudo foi baseado em um trabalho etnográfico realizado no Japão no período de janeiro de 2003 a dezembro de 2006, e enfocou as atividades de um grupo de católicos entre os brasileiros no Japão. No total foram realizadas 15 entrevistas com os membros. Veremos que os migrantes encontram no grupo além de serviços religiosos uma rede de apoio social que os ajudam a lidar com o sentimento de vulnerabilidade. Entretanto, por trás desta atividade de orientação e apoio religioso existe um poder eclesiástico que, indiretamente, controla a conduta pessoal e moral e exerce uma ação regulatória na vida dos migrantes.This paper analyzes the role of religiosity and the impact of social support in the lives of Brazilian migrants in Japan. Despite being in Japan for over two decades, the Brazilians are not integrated into the local society. This social alienation has a negative effect on the health of the migrants, making them prone to mental and physical distress. The lack of language skills prevents the migrants from looking for professional help, and even if they seek for it they cannot express themselves properly. In this context, the migrants found support among their compatriots and religious groups. This essay is based on

Developmental post-natal stress can alter the effects of pre-natal stress on the adult redox balance.

2013-09-15

Across diverse vertebrate taxa, stressful environmental conditions during development can shape phenotypic trajectories of developing individuals, which, while adaptive in the short-term, may impair health and survival in adulthood. Regardless, the long-lasting benefits or costs of early life stress are likely to depend on the conditions experienced across differing stages of development. Here, we used the Japanese quail (Coturnix coturnix japonica) to experimentally manipulate exposure to stress hormones in developing individuals. We tested the hypothesis that interactions occurring between pre- and post-natal developmental periods can induce long-term shifts on the adult oxidant phenotype in non-breeding sexually mature individuals. We showed that early life stress can induce long-term alterations in the basal antioxidant defences. The magnitude of these effects depended upon the timing of glucocorticoid exposure and upon interactions between the pre- and post-natal stressful stimuli. We also found differences among tissues with stronger effects in the erythrocytes than in the brain in which the long-term effects of glucocorticoids on antioxidant biomarkers appeared to be region-specific. Recent experimental work has demonstrated that early life exposure to stress hormones can markedly reduce adult survival (Monaghan et al., 2012). Our results suggest that long-term shifts in basal antioxidant defences might be one of the potential mechanisms driving such accelerated ageing processes and that post-natal interventions during development may be a potential tool to shape the effects induced by pre-natally glucococorticoid-exposed phenotypes.

Full Text Available Niemodlin countryside (c. 300 km2 is situated in the south-western part of Opole Silesia, SW Poland. Forests occupy c. 40%, arable grounds – 1/3, and meadows and pastures – 7%. There are 31 fish-ponds with a total diked surface of 663 ha. The paper presents results of field investigations carried out during the years 2002-2007 and an analysis of changes in the breeding avifauna over the last 56 years. During the years 2002-2007, 123 breeding and 11 probably breeding bird species were recorded in this area. During the years 1962-2007 151 species were recorded as breeding residents; and additional five species – as probably breeding resident. The following species were recorded as breeding for the first time in 1962-2007: Haliaeetus albicilla, Larus canus, Motacilla cinerea, Saxicola torquata, Locustella luscinioides, Ficedula albicollis, Corvus corax and Carpodacus erythrinus. In the same period the following species became extinct: Podiceps nigricollis, Anas clypeata, Milvus milvus, and Tringa glareola. The following species increaed in numbers in 1962-2007: Coturnix coturnix, Grus grus, Columba oenas, Apus apus, Dryocopus martius, Dendrocopos medius, Motacilla cinerea, Saxicola torquata and Corvus corax. In the same period, Tachybaptus ruficollis, Podiceps cristatus, Podiceps grisegena, Ciconia ciconia, Aythya nyroca, Perdix perdix, Gallinago gallinago, Larus ridibundus, Tyto alba, Alcedo atthis, Picus viridis, Riparia riparia and Corvus cornix decreased in numbers. The areas with the highest concentration of rare and endangered species are postulated to be protected as nature reserves, landscape parks and other spatial forms of nature conservation.

A Method for Fast Assessment of OP/CB Exposure in the Japanese Quail (Coturnix coturnix japonica Using Combined Esterases Enzyme Activity as Biomarkers

Full Text Available The aims of this study were to investigate the presence of different esterase activities in plasma and liver for Japanese quail and to combine determination of both carboxylesterase and cholinesterase as biochemical biomarker in order to identify the effects of carbamate and organophosphate compounds exposure. Carboxylesterase exhibits larger sensitivity to carbamate and organophosphate compounds than to cholinesterase and is present at higher levels. This permitted nature and distribution of carboxylesterase or cholinesterase to be measured. One predominant toxicological form of enzyme level constant in its patterns of motivation and inhibition with cholinesterase was identified in plasma with an apparent Michaelis constant for butyrylthiocholine iodide of 0.394 mM. Carboxylesterase activity in liver was considered by its preferential hydrolysis of the S-phenyl thioacetate. A concentration dependent decrease of carboxylesterase and cholinesterase has demonstrated during in vitro incubation of malathion, parathion, and trichlorfon in the range 0.125–2 mM, while with methomyl was in the range 0.25–4 mM. When quail (n=15 was exposed orally for 48 h to concentrations of carbamate or organophosphate compounds of 3–200 mg/kg, the percentage inhibition of cholinesterase was in each case larger than that of carboxylesterase and reached statistical significance (P<0.05 at lower concentrations.

Full Text Available Dans cet article, on cherche à analyser le système politique japonais moderne depuis une structure comparée - depuis celle surtout des multiples modernités et de leurs racines civilisatrices. On part du fait que, alors que le système politique japonais moderne est en termes organisationnels un système constitutionnel moderne, semblable à celui de l'Europe, sa dynamique politique se manifeste dans la structure et les orientations des mouvements revendicatifs, dans la constitution du problème de la communauté et de la société civile, ainsi que dans la dynamique des changements de régime très différente de celle des européens. Ces différences se trouvent ancrées dans des prémisses non-axiales de la civilisation japonaise, qui se sont figées tout au long de son expérience historique et qui modèlent quelques-unes des principales différences entre la Révolution de Meiji et les grandes Révolutions.

There is a lack of information concerning the prevalence of Toxoplasma gondii infection in wild birds in Mexico. In the present study, serum samples and tissues from 653 birds from Durango State, Mexico, were evaluated for T. gondii infection. Antibodies to T. gondii (modified agglutination test, titer 1∶25 or higher) were found in 17 (2.6%) of the 653 birds, including 1 of 2 curve-billed thrashers (Toxostoma curvirostre), 2 (1 Anas platyrhynchos, 1 Anas diazi) of 4 ducks, 1 of 2 eagles (Aquila sp.), 5 (27.8%) of 18 great-tailed grackles (Quiscalus mexicanus), 7 (1.3%) of 521 rock pigeons (Columba livia), and 1 (14.3%) of 7 quail (Coturnix coturnix). The seroprevalence of T. gondii infection in birds captured in a park outside the city zoo (11.6%, 8/69) was significantly higher than that found in birds from other regions (1.5%, 9/584, OR  =  8.38; 95% CI: 2.82-24.77; P  =  0.0001). Brains and hearts of 23 birds (17 seropositive, 6 seronegative) were bioassayed in mice for the isolation of T. gondii . Viable T. gondii was isolated from 1 of 7 seropositive pigeons. The DNA obtained from the T. gondii isolate from the pigeon was genotyped using the PCR-RFLP typing using 11 markers (B1, SAG1, SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, and Apico) and revealed an atypical genotype. This is the first report of T. gondii infection in great-tailed grackles, the Mexican duck, and curved-billed thrashers and the first survey of wild birds in Mexico.

Wild birds are continually exposed to many anthropogenic and natural stressors in their habitats. Over the last decades, mass mortalities of wild birds constitute a serious problem and may possibly have more causations such as natural toxins including cyanotoxins, parasitic diseases, industrial chemicals and other anthropogenic contaminants. This study brings new knowledge on the effects of controlled exposure to multiple stressors in birds. The aim was to test the hypothesis that influence of cyanobacterial biomass, lead and antigenic load may combine to enhance the effects on birds, including modulation of antioxidative and detoxification responses. Eight treatment groups of model species Japanese quail (Coturnix coturnix japonica) were exposed to various combinations of these stressors. The parameters of detoxification and oxidative stress were studied in liver and heart after 30 days of exposure. The antioxidative enzymatic defense in birds seems to be activated quite efficiently, which was documented by the elevated levels and activities of antioxidative and detoxification compounds and by the low incidence of damage to lipid membranes. The greatest modulations of glutathione level and activities of glutathione-S-transferase, glutathione peroxidase, glutathione reductase, superoxide dismutase, catalase and lipid peroxidation were shown mostly in the groups with combined multiple exposures. The results indicate that the antioxidative system plays an important role in the protective response of the tissues to applied stressors and that its greater induction helps to protect the birds from more serious damage. Most significant changes of these "defense" parameters in case of multiple stressors suggest activation of this universal mechanism in situation with complex exposure and its crucial role in protection of the bird health in the environment.

Full Text Available The objective of this study was to estimate the variance components for body weight in Japanese quails by Bayesian procedures. The body weight at hatch (BWH and at 7 (BW07, 14 (BW14, 21 (BW21 and 28 days of age (BW28 of 3,520 quails was recorded from August 2001 to June 2002. A multiple-trait animal model with additive genetic, maternal environment and residual effects was implemented by Gibbs sampling methodology. A single Gibbs sampling with 80,000 rounds was generated by the program MTGSAM (Multiple Trait Gibbs Sampling in Animal Model. Normal and inverted Wishart distributions were used as prior distributions for the random effects and the variance components, respectively. Variance components were estimated based on the 500 samples that were left after elimination of 30,000 rounds in the burn-in period and 100 rounds of each thinning interval. The posterior means of additive genetic variance components were 0.15; 4.18; 14.62; 27.18 and 32.68; the posterior means of maternal environment variance components were 0.23; 1.29; 2.76; 4.12 and 5.16; and the posterior means of residual variance components were 0.084; 6.43; 22.66; 31.21 and 30.85, at hatch, 7, 14, 21 and 28 days old, respectively. The posterior means of heritability were 0.33; 0.35; 0.36; 0.43 and 0.47 at hatch, 7, 14, 21 and 28 days old, respectively. These results indicate that heritability increased with age. On the other hand, after hatch there was a marked reduction in the maternal environment variance proportion of the phenotypic variance, whose estimates were 0.50; 0.11; 0.07; 0.07 and 0.08 for BWH, BW07, BW14, BW21 and BW28, respectively. The genetic correlation between weights at different ages was high, except for those estimates between BWH and weight at other ages. Changes in body weight of quails can be efficiently achieved by selection.

Full Text Available Background: Early nutrition of chicks with beneficial bacteria might help in occupying the inner surface of the intestinal tract. Interference of pathogens in intestinal microbiota is well known as barrier effect, bacterial interference, and competitive exclusion. Objectives: It was hypothesized that competitive exclusion in Japanese quails with a blend of beneficial bacteria (Aquablend Avian® probiotic would enhance quails’ growth performance and intestinal mucosal morphology. Furthermore, the study was performed at 2100 m above sea level at Shahrekord University, so another hypothesis was the capability of the probiotic for inhibiting right heart failure. Materials and Methods: One hundred fifty-six Japanese quails were divided into 4 groups: 2 groups (Aquablend and control at standard environmental temperature and 2 (Aqua-stress and Cont-stress at cold-hypoxic environmental situation. Aquablend groups received the probiotic in the first 3 days of life in drinking water (0.5 g/100 birds/day. Results: Feed conversion ratio (FCR was significantly reduced at the end of the experiment (day 35 in both Aquablend and aqua-stress groups compared to control and cont-stress groups, respectively (P 0.05. Cont-stress group had higher RV: TV ratio (0.28 and heterophil: lymphocyte (H: L ratio (1.22 than aqua-stress group: (0.25 and (1.20, respectively (P > 0.05. Data regarding to intestinal mucosa morphology was controversial but the probiotic was able to elevate duodenum villi surface (P < 0.05 and also jejunum and ileum lamina propria thickness. Conclusion: Obtained data suggests that addition of Aquablend Avian® probiotic in the first 3 days of life may improve growth performance and some intestinal mucosa characteristics of Japanese quails. Moreover, the probiotic might reduce right heart failure and stress induced by cold-hypoxic situation.

Full Text Available A total of 240, one-day-old quail chicks (Coturnix coturnix japonica were used to study the effects of Artichoke leaf meal (ALM and vitamin E in diet on growth performance, ileal microbial populations and intestinal morphology in a 42-d trial. This experiment was performed as a completely randomized design with 4 replicates of 15 quails each, using a 4 × 2 factorial arrangement with diet and gender as the main effects. Four dietary treatments were formulated by addition of 2 levels (1.5 and 3 percent of ALM and 300 mg/Kg vitamin E to the basal diet. Supplementing basal diet with ALM did not improve growth performance at different rearing periods, whereas dietary vitamin E increased feed intake and body weight gain at day 21 of age (P. The ileal populations of lactobacillus and coliforms was not affected by dietary ALM treatments, whereas vitamin E increased the population of total aerobic bacteria (P≤0.04. The ileal villus height (P≤0.01 and crypt depth (P≤0.008 were reduced in quails fed on diets with ALM and vitamin E. The quails fed diets containing 3 percent ALM and 300 mg/Kg vitamin E had higher villus height:crypt depth ratio. The thickness of muscularies (P≤0.04 and mucosa (P≤0.0007 layers were decreased in birds fed diets containing ALM than control birds. Birds treated with ALM and vitamin E showed a shorter intestinal length (P≤0.02 and a lower pancereas relative weight. The results of this study showed that supplementing diet by ALM (1.5 and 3% and 300 mg/Kg vitamin E did not improve growth performance, ileal microbiota pupolations and intestinal morphometric indices in Japanese quail.

Multilocus profiles were investigated in five different species of Galliformes (ring-necked pheasant Phasianus colchicus, Indian peafowl Pavo cristatus, Japanese quail Coturnix coturnix japonica, domestic chicken Gallus gallus, and red grouse Lagopus lagopus scoticus) using two human multilocus probes (33.6 and 33.15) in combination with each of four restriction enzymes (AluI, DdeI, HaeIII or HinfI). All the species show a DNA fingerprint-like pattern using at least one restriction enzyme in combination with each multilocus probe. The number of bands detected and the value of the index of similarity for each species differ significantly between the profiles obtained with each multilocus probe. Some enzyme/probe combinations reveal strong cross-hybridization of the multilocus probes with satellite or satellite-like DNA sequences in pheasant, peacock, quail and chicken, which partially or completely prevented scoring of the profile. The choice of restriction enzyme was found to influence the number of bands, the value of the index of similarity and the probability of obtaining an identical fingerprint between unrelated individuals. The Mendelian inheritance and independent segregation of the fragments detected using AluI was investigated in three species (ring-necked pheasant, Indian peafowl and red grouse). Some bands were shown to be tightly linked. An extreme case was encountered in the red grouse, where 12 of the 15 bands scored in one parent represented only two, apparently allelic, haplotypes and so derived from a single locus. However, fingerprint patterns will often be adequate for use in paternity analyses, such as in behavioural studies, despite the occurrence of haplotypic sets of bands. Identical DNA multilocus profiles were sometimes observed between captive-bred siblings in one species. These results emphasize the desirability of determining, in each new species, the optimal experimental conditions as a preliminary to any behavioural or population

Although, use of animal species in disease treatment and culture practices is as ancient as that of plant species; however ethnomedicinal uses and cultural values of animal species have rarely been reported. Present study is the first report on the medicinal uses of mammals and bird species in Pakistan. Questionnaires and semi-structured interviews were applied to collect qualitative and quantitative data from local informants (N = 109). Relative frequency of mention (RFM), fidelity level (FL), relative popularity level (RPL), similarity index (SI) and rank order priority (ROP) indices were used to analyzed the data. One hundred and eight species of animals, which include: 83% birds and 17% mammals were documented. In total 30 mammalian and 28 birds' species were used to treat various diseases such as rheumatic disorders, skin infections and sexual weakness among several others. Fats, flesh, blood, milk and eggs were the most commonly utilized body parts. Bos taurus, Bubalus bubalis, Capra aegagrus hircus, Felis domesticus, Lepus nigricollis dayanus and Ovis aries (mammals) and Anas platyrhynchos domesticus, Columba livia, Coturnix coturnix, Gallus gallus and Passer domesticus (birds) were the highly utilized species. Medicinal and cultural uses of 30% mammals and 46% birds were reported for the first time, whereas 33% mammals and 79% birds depicted zero similarity with previous reports. Present study exhibits significant ethnozoological knowledge of local inhabitants and their strong association with animal species, which could be helpful in sustainable use of biodiversity of the region. Additionally, in vitro and in vivo evaluation of biological activities in the mammalian and birds' species with maximum fidelity level and frequency of mention could be important to discover animal based novel drugs.

Full Text Available ABSTRACT This study was carried out to investigate the effects of eggshell colour and spot properties (colour and size of the spot area on growth performance and carcass traits of Japanese quail (Coturnix coturnix japonica eggs. Study material were allocated to five groups according to their eggshell and spot colours: black spots on greyish white coloured eggshell (I, blue spots on greyish white coloured eggshell (II, diffuse brown spots on greyish brown coloured eggshell (III, brown spots on light green colored eggshell (IV, and small brown spots on greyish brown coloured eggshell (V. The size of the spotted area was determined in each egg group using digital image analysis. The groups did not differ for body weight and length of the shank at the end of the growth period. However, the groups differed significantly for carcass yield after slaughter (not eviscerated and carcass yield. These parameters were highest in Group I (82.08 and 76.09% and lowest in Group III (80.20 and 73.86%. Digital image analysis demonstrated that heart length, cardiac fat area, gizzard width, and intestine length varied between the groups. Cardiac fat area was largest in Group III (0.86 cm2 and smallest in Group V (0.65 cm2. Gizzard width was greatest in Group I (2.63 cm and smallest in Group V (2.47 cm. Intestine length was greatest in Group V (78.45 cm and smallest in Group IV (72.39 cm. Body weight, shank length, and slaughter and carcass weight do not vary in relation to eggshell colour or the size of the spotted area. The lengths of intestine and heart, gizzard width, and cardiac fat area do vary in relation to eggshell colour or the size of the spotted area.

Effects of first formant onset frequency on [-voice] judgments result from auditory processes not specific to humans.

Science.gov (United States)

Kluender, K R; Lotto, A J

1994-02-01

When F1-onset frequency is lower, longer F1 cut-back (VOT) is required for human listeners to perceive synthesized stop consonants as voiceless. K. R. Kluender [J. Acoust. Soc. Am. 90, 83-96 (1991)] found comparable effects of F1-onset frequency on the "labeling" of stop consonants by Japanese quail (coturnix coturnix japonica) trained to distinguish stop consonants varying in F1 cut-back. In that study, CVs were synthesized with natural-like rising F1 transitions, and endpoint training stimuli differed in the onset frequency of F1 because a longer cut-back resulted in a higher F1 onset. In order to assess whether earlier results were due to auditory predispositions or due to animals having learned the natural covariance between F1 cut-back and F1-onset frequency, the present experiment was conducted with synthetic continua having either a relatively low (375 Hz) or high (750 Hz) constant-frequency F1. Six birds were trained to respond differentially to endpoint stimuli from three series of synthesized /CV/s varying in duration of F1 cut-back. Second and third formant transitions were appropriate for labial, alveolar, or velar stops. Despite the fact that there was no opportunity for animal subjects to use experienced covariation of F1-onset frequency and F1 cut-back, quail typically exhibited shorter labeling boundaries (more voiceless stops) for intermediate stimuli of the continua when F1 frequency was higher. Responses by human subjects listening to the same stimuli were also collected. Results lend support to the earlier conclusion that part or all of the effect of F1 onset frequency on perception of voicing may be adequately explained by general auditory processes.(ABSTRACT TRUNCATED AT 250 WORDS)

Full Text Available Este trabajo es una contribución al debate acerca de la transferibilidad del sistema japonés de producción (S J P a otros contextos culturales, y en particular a México. El debate ha estado polarizado entre los que afirman que el SJP no es transferible a otras culturas por ser específico a la cultura japonesa y los que, por el contrario, argumentan que el S J P sí es transferible en la medida en que consiste en una serie de innovaciones organizacionales que bien pueden funcionar en otros contextos culturales. Desde luego, esta descripción del debate es más bien típico-ideal de las posiciones opuestas en el mismo, pero la mayoría de los participantes han planteado argumentos y datos que apoyan ya sea su posición ? culturalista? o la ?organizacional? , como aquí las hemos designado. Nuestro argumento es que lo más promisorio sobre la transferibilidad del S J P es un enfoque sintético que combine ambas perspectiva s. Más específicamente, sostenemos que la tesis organizacional es la más fuerte de las dos. Dadas ciertas similitudes culturales a las japonesas, sin embargo, el S J P se puede transferir más exitosamente y en un menor periodo de tiempo. Para apoyar nuestra argumentación, utilizamos tanto materiales secundarios como un estudio de caso de la planta automotriz de Honda de México. A partir de la información existente, primero discutimos varios estudios de caso sobre la transferencia del S J P a otros países de capitalismo avanzado, en los que los resultados son ambivalentes, pero tienden a apoyar la tesis organizacional. Luego presentamos nuestro material de campo y los datos de una encuesta que aplicamos a los obreros de la Honda de México en 1997,mismos que apoyan nuestra hipótesis sintética.

Full Text Available Com o objetivo de avaliar o efeito da debicagem e do tipo de bebedouro sobre o desempenho produtivo de codornas japonesas, 672 fêmeas de codornas de um dia foram usadas em um delineamento inteiramente casualizado e distribuídas em um dos três tratamentos como não-debicagem; debicagem até 1/3 dos bicos; e cauterização, com oito repetições de 28 aves na fase de cria. As aves foram debicadas aos 21 dias de idade e, no 35 dia, foram avaliados o ganho de peso, o consumo de ração, a conversão alimentar e a taxa de mortalidade. Aos 39 dias, 576 codornas foram remanejadas para gaiolas de postura, distribuídas em esquema fatorial 3 × 2, composto de três tipos de debicagem e dois tipos de bebedouro (taça e nipple, de modo que cada combinação foi avaliada com quatro repetições de 24 aves. A fase de produção teve início quando as aves atingiram 50% de produção de ovos, aos 60 dias de idade. As codornas submetidas a debicagem por cauterização apresentaram menor ganho de peso e menor consumo de ração na fase de cria. O estresse pela dor com a debicagem por cauterização pode justificar não só o menor consumo e o menor ganho de peso, como também a maior mortalidade. Infere-se que este método, por ser mais demorado, tenha provocado mais dor e maior nível de estresse, piorando o desempenho das aves. A debicagem de 1/3 dos bicos cortados pode ter ocasionado estresse menos intenso às aves, não interferindo no desempenho. Não se observaram diferenças no desempenho das aves e na qualidade de ovos entre os tipos de bebedouro e métodos de debicagem utilizado na fase de produção. O método de debicagem por cauterização influencia o desempenho de codornas na fase de cria, mas, na fase de produção, assim como o tipo de bebedouro utilizado, não interfere no desempenho das aves nem na qualidade de ovos.A total of 672 one day old- female quails was allotted to a completely randomized experimental design, with three treatments

Culturas fan y cultura masiva: prácticas e identidades juveniles de otakus y gamers

Full Text Available [es] El objetivo de este trabajo es dar cuenta de cómo, en torno de productos mediáticos y prácticas socioculturales comunes, los fans del anime o series animadas japonesas –autodenominados otakus– y los fans de los videojuegos japoneses –autodenominados gamers– elaboran un universo simbólico propio y compartido sobre el cual pueden construir identidades juveniles que son diferentes entre sí. El interés por las significaciones que producen estos fans surge del auge de la cultura masiva japonesa en la Argentina, evidenciado, por ejemplo, en la transmisión de distintos animes por las emisoras nacionales de televisión por aire Telefe y Canal 9, en ciclos organizados por la Facultad de Ciencias Sociales de la Universidad de Buenos Aires y en documentales del Canal Encuentro –gestionado por el Ministerio de Educación de la Nación Argentina–, así como en la promoción institucional de dichas series animadas y de los videojuegos en Tecnópolis –muestra nacional de arte, ciencia y tecnología–, la Feria Internacional del Libro de Buenos Aires y la Agenda Cultural del Gobierno de la Ciudad de Buenos Aires. Es así como, desde una perspectiva socioantropológica y comunicacional, cabe reflexionar sobre los usos y reapropiaciones que hacen los jóvenes fans de los objetos de la cultura de masas japonesa que viven en la Ciudad de Buenos Aires. Asimismo, hay que tener en cuenta que las distintas prácticas desarrolladas en torno del consumo de estos productos están encuadradas dentro de flujos globales que generan procesos interculturales de construcción de identidades, inscriptos a la vez en relaciones de poder intraculturales y procesos alternativos de producción cultural.

Pharmaceuticals and heavy metals such as diclofenac and lead, respectively, have been identified as environmental contaminants toxic to birds and posing serious threats to declining populations of raptors worldwide. The aim of the present study was to test the hypothesis that a sublethal combination of non-steroidal anti-inflammatory drugs and lead induces more pronounced effects than single exposures in birds. A total of 40 Japanese quails (Coturnix coturnix japonica) at the age of 2 months and average weight of 180g were on a random basis divided into four experimental groups of 10 specimens (i.e., control, diclofenac, lead, and lead+diclofenac exposures). Six lead shots in the total weight of 1.5 grams were inserted into the crop on day 0 of the experiment, while a total of 5 mg/kg of diclofenac administered intramuscularly were divided into treatments on days 0 and 5. Group responses were compared using haematology and biochemistry after 10 days. There was no mortality in control and both single and combined diclofenac and lead exposure groups, nor did the birds show any clinical signs of intoxication. Univariate analyses of blood parameters yielded a decrease in haematocrit in birds exposed to both substances when compared with the control, a lower haemoglobin level of the lead-exposed group, increased activity of aspartate aminotransferase in the NSAIDs-exposed group, increased activity of alkaline phosphatase in birds exposed to a combination of diclofenac and lead, and a higher phosphorus level in the lead-exposed group. The principal component analysis revealed no multivariate pattern of responses of blood parameters and did not allow separation of exposure groups from controls when the variables and samples were projected onto a two dimensional space. Results of the present study can enhance understanding of combination toxicity of veterinary drugs and heavy metals in birds, i.e. a scenario that has become environmentally relevant in recent decades

The objective of this study was to examine the hypothesis that a combination of cyanobacterial biomass containing microcystins, acetylcholinesterase inhibitor and anticoagulant can enhance avian toxic effects produced by single exposures only. A total of 48 two-month-old Japanese quails (Coturnix coturnix japonica) with average body weight of 160 g were randomly divided into 8 experimental groups of six birds and sex ratio of 1:1. Experimental groups of control Japanese quails (C) and birds exposed to single and combined sub-lethal doses of paraoxon (P), bromadiolone (B), and microcystins in cyanobacterial biomass (M) included: C, P, P+B, B, B+M, P+M, M, and P+B+M. During the 10-day exposure birds in the respective groups received biomass containing 61.62 µg microcystins daily (i.e. 26.54 µg MC-RR, 7.62 µg MC-YR and 27.39 µg MC-LR), two 250 μg/kg doses of paraoxon, and two 500 mg/kg doses of bromadiolone. Group responses were compared using standard plasma biochemistry and antioxidant/oxidative stress parameters in tissues. While single and double combinations of toxicants induced responses in individual biochemical parameters measured and evaluated using univariate statistical analysis, those in the triple exposure were most extensive. The principal component analysis of antioxidant/oxidative stress parameters (glutathione reductase, lipid peroxidation, and ferric reducing antioxidant power) in tissues (liver, kidney, heart, brain, lungs, gonads, and pectoralis major muscle) clearly separated the triple group (P+B+M) from all single and double exposure groups and the control and indicated thus marked joint effects in the overall pattern of antioxidant/oxidative stress responses of this group. The separation was driven by the modification of the ferric reducing antioxidant power levels in heart and brain and the cardiac lipid peroxidation level, in particular. This experiment contributes to the understanding of the pathogenic mechanisms of combined sub

Vertebrate host specificity, experimental laboratory vectors, and a description of Plasmodium (Novyella) kempi sp. n. from eastern wild turkeys (Meleagris gallopavo silvestris Vieillot) in Iowa are presented. Plasmodium kempi is infective for domestic turkeys, bobwhites (Colinus virginianus), chukars (Alectoris graeca), guinea fowl (Numida meleagris), peacocks (Pavo cristatus), and canaries (Serinus canaria), produces a transient infection in mallards (Anas platyrhynchos) and domestic geese (Anser anser), but will not infect ring-necked pheasants (Phasianus colchicus), pigeons (Columba livia), Japanese quail (Coturnix coturnix), leghorn white chickens (Gallus gallus), or starlings (Sturnus vulgaris). Oocysts and (or) sporozoites were recovered from 68% (84/124) and 98% (60/61) of the Culex pipiens pipiens and C. tarsalis examined, respectively. Oocysts developed faster and sporozoites invaded the salivary glands sooner in C. tarsalis (6 days) than in C. p. pipiens (7 days). Culex tarsalis transmitted P. kempi more effectively than C. p. pipiens, although both species were capable of transmitting the parasite by natural feeding. Oocysts developed and sporozoites also were produced in C. restuans, but its ability to transmit the parasite was not determined. Aedes aegypti (Rockefeller strain) and A. triseriatus were refractive to P. kempi. Plasmodium kempi produces trophozoites with large refractile globules and fine cytoplasmic extensions, mature schizonts in the form of a condensed fan containing four to eight nuclei (usually 5), and elongate gametocytes with irregular borders. All stages are confined almost exclusively to mature erythrocytes, with no effect on host cell size or position of host cell nucleus. Plasmodium kempi is most similar morphologically to P. (Novyella) hexamerium and P. (Novyella) vaughani. It differs from P. hexamerium in having large refractile globules in trophozoites and immature schizonts, an inability to infect starlings, an absence of

Full Text Available The aim of this research is to characterise the wild rabbit (Oryctolagus cuniculus commercial game farms in Spain using variables related to structure, management and marketing. To this end, a structured survey was administered in 2009 to 21 privately-owned farms. This subsector was an average age of 13. The average size of the breeding stock of the farms was 431 does and 64 bucks. Eighty-five percent of the farms kept all or part of the breeding stock in cages and 38.1% used artificial insemination. All the farms carried out breeder self-replacement, 4.8% by buying wild rabbits from other farms, whereas 38.1% captured wild rabbits for this purpose. Nineteen percent of the wild rabbit game farms also produced other game species, mainly red-legged partridge (Alectoris rufa, pheasant (Phasianus colchicus and quail (Coturnix coturnix. Fourteen percent of the farms supplied wild rabbits to be used as prey to be released in programmes for the conservation of endangered predators, and 38.1% supplied breeding rabbits to be used by other farms to replace culled animals. Eighty-six percent of the farms offered the service of transporting the animals from the farm to the hunting grounds to their clients, and 14.3% advised customers on how to successfully release and restock hunting grounds. Seventy-six percent of the farms marketed their products throughout Spain, and 38.1% exported wild rabbits to neighbouring countries, mainly Portugal and France. Forty-three percent of the farms advertised themselves in hunting magazines, 19.1% promoted themselves by attending livestock and game fairs, and 38.1% had their own websites. In conclusion, this alternative rabbit production system constitutes a well-established subsector in Spain, despite being only 2 decades old. It also seems that it has not yet reached its development maturity. It shows wide diversity in terms of farm size and structure, as well as marketing and promotional activities.

1. The effects of ascorbic acid (L-ascorbic acid) and melatonin supplementation on performance, carcase characteristics, malondialdehyde (MDA) as lipid peroxidation indicator, ascorbic acid, retinol, tocopherol and mineral status in the Japanese quail (Coturnix coturnix japonica) exposed to high ambient temperature were evaluated. 2. Two hundred and forty Japanese quails (10 d old) were randomly assigned to 8 treatment groups consisting of 10 replicates of three birds each. The birds were kept in a temperature-controlled room at 22 degrees C (Thermoneutral, TN groups) or 34 degrees C (for 8 h/d; 09:00 to 17:00 h; Heat stress, HS groups). Birds in both TN and HS were fed either a basal (control) diet or the basal diet supplemented with 250 mg of L-ascorbic acid/kg of diet (Ascorbic acid group), 40 mg of melatonin/kg of diet (Melatonin group) or both (Ascorbic acid + Melatonin group). 3. Supplementing heat-stressed quails with ascorbic acid and melatonin improved performance compared with the control group. Effects generally were greatest in quails supplemented with both ascorbic acid and melatonin. 4. Although supplementation did not consistently restore the concentrations of serum ascorbic acid, retinol and tocopherol to those of TN groups, these concentrations increased significantly with supplementation. Furthermore, serum and liver MDA and serum cholesterol and glucose concentrations were lower in the supplemented groups than in the heat-stressed controls. 5. Within each environment, excretion of Ca, P, Mg, Zn, Fe and Cr were lowest in the combination group and, in all cases, highest in the HS group. Interactions between diet and temperature were detected for live weight gain, cold carcase weight, MDA, ascorbic acid, tocopherol concentrations and excretion of zinc. 6. The results of the study indicate that ascorbic acid and melatonin supplementation attenuate the decline in performance and antioxidant and mineral status caused by heat stress and such

Young Japanese quail (Coturnix japonica) were administered NaF for 16 d either in their diet or by esophageal intubation. Based on the total fluoride ion (Emg F-) intake over the l6-d experimental period, fluoride administered by intubation was at least six times more toxic than that fed in the diet. Dietary concentrations of 1,000 ppm F- (Emg F- for 16 d = approx. 144) produced no mortality, whereas intubated doses produced 73% or greater mortality in all groups administered 54 mg F- /kg/d or more (Emg F- for 16 d _ approx. 23 mg). GraphIc companson of the regression of log F- ppm in femurs/mg F- intake showed that fluoride levels in the femurs of quail administered fluoride by intubation were higher than in those administered fluoride in the diet.

Ninety quails were used, distributed in randomized blocks with 3 treatments (0 – control; 250 and 750 mg symbiotic and plant extract/kg of diet, five repetitions and six birds per cage. Feed intake, feed conversion, production and weight of eggs, viability, TIT, II and H:L were evaluated. Results showed that the addition of the product to the diet did not affect the performance, however, it decreased the TIT, II and the H:L of quails which received the highest level of the product in the diet. Thus, the use of symbiotic and plant extract in the diet has been promising regarding the behavioral and physiological parameters, decreasing the stress of the animals, mainly for the level of 750 mg/kg diet.

Full Text Available The objective of this review was to present aspects related to maintaining the quality of quail eggs addressing the main parameters that must be evaluated and pointing their importance in order to characterize its commercial quality. The excellent performance of quails in posture process depends on a complex interaction between nutrition and a variety of internal factors. The quail egg weight ranges from 9 to 13 grams and is of considerable importance for the assessment of quality. During storage there is loss of egg weight. This loss is associated with the evaporation of water by means the pores of the shell which also determines the increase of the air chamber that affects the specific gravity. The Haugh Unit is the parameter most commonly used to express the quality of the eggs. The higher the value of the Haugh unit, better the quality of the eggs. As regards the quality of eggs, it becomes evident that longer periods of storage, the internal egg quality tends to decrease linearly and sharply to the no refrigerated. The storage temperature is shown associated the rate of changes occurring in the egg during storage.

Estas inversiones tuvieron altos rendimientos no sólo en términos de producción de arroz sino también en términos de construcción de capacidad institucional y creación de infraestructura. El caso koreano no es una anomalía sino un ejemplo algo singular e interesante de desarrollo agrícola que antecede a una rápida expansión industrial.

Population trends of Goričko agricultural landscape birds

2017-12-01

Full Text Available Due to numerous bird surveys in the past 20 years, the avifauna of Goričko is relatively well known. For some species, the very first national ecological researches were conducted in this area. The article summarizes all bird surveys so far. It presents population trends of farmland species which is one of the most threatened bird groups in Europe. Most of the qualifying species of this habitat that are protected within the Natura 2000 network have suffered a decline at Goričko, specifically Quail Coturnix coturnix, Scops Owl Otus scops, Hoopoe Upupa epops, Woodlark Lullula arborea and White Stork Ciconia ciconia. The number of breeding pairs of the latter has not changed, but its fecundity has decreased. Furthermore, populations of other farmland bird species have decreased, for example Skylark Alauda arvensis, Stonechat Saxicola rubicola, Serin Serinus serinus and Common Linnet Linaria cannabina, as well as butterfly populations and tracts of grassland habitat types. National agricultural and nature conservation policies are evidently inefficient in protecting the biodiversity of Goričko. The most probable cause for bird population decline is agricultural intensification, which manifests itself at Goričko as disappearance and intensification of meadows, land consolidation, degradation of traditional orchards and use of pesticides. As a result of land consolidation hedges, uncultivated strips between fields, individual trees and bushes and minority habitat types are disappearing, whereas the surface of arable fields is increasing. Nature conservation measures performed by the Public Institute Goričko Nature Park with the support of DOPPS – BirdLife Slovenia volunteers seem to be efficient, but are spatially and temporally constrained. For this reason, they cannot serve as a substitute for insufficient systemic financing which could be improved by substantive and financial reform of the agri-environmental scheme. Currently, a negligible

Chromium picolinate is used in the poultry diet because of its antistress effects in addition to the fact that the requirement for it is increased during stress. This study was conducted to determine if the negative effects of high ambient temperature (34 degrees C) on egg production, egg quality, antioxidant status, and cholesterol and mineral content of egg yolk could be alleviated by combination of chromium picolinate and biotin (0.6/2.0; Diachrome, as formulated by Nutrition 21 Inc.), in laying Japanese quails (Coturnix coturnix japanica). Quails (n= 240; 50 d old) were divided into 8 groups, 30 birds per group. The quails were fed either a basal diet or the basal diet supplemented with 2, 4, or 8 mg of Diachrome/kg diet. Birds were kept at 22 degrees C and 53% relative humidity (RH). At 14 wk of age, the thermoneutral (TN) group remained in the same temperature as at the beginning of experiment, whereas the heat stress (HS) group was kept in an environment-controlled room (34 degrees C and 41% RH) for 3 wk. Heat exposure decreased performance when the basal diet was fed (p = 0.001). Diachrome supplementation at 4 and 8 mg/kg diet, increased feed intake (p = 0.05), egg production (p = 0.05), feed efficiency (p = 0.01), egg weight (p = 0.05), and Haugh unit (p = 0.01) in quails reared under heat stress conditions. Heat exposure increased concentrations of serum malondialdehyde (MDA) (p = 0.001), glucose, and cholesterol (p = 0.01), which were elevated by supplemental Diachrome (p < or = 0.05). Egg yolk Cr, Zn, and Fe (p = 0.01) concentrations increased linearly, whereas MDA and cholesterol concentrations decreased (p = 0.05) as dietary Diachrome supplementation increased in HS groups. Similar effects of supplementation on serum levels of glucose and cholesterol (p = 0.05) and egg yolk concentrations of cholesterol (p = 0.05) and Cr (p = 0.01) were observed in TN groups. No significant differences in other values were observed in the TN groups. Results of the

Full Text Available Os mangás representam um modelo textual originado no Japão, que vem cada vez mais ocupando espaço na mídia ocidental. Em meados de 1980, surgiram os primeiros mangás Yaoi. Inicialmente, este subgênero de “shojo manga” marcou seu espaço por ter sido desenhado, escrito e publicado por fãs de mangás, ironizando a hegemonia masculina nesta mídia. A receptividade do público feminino contribui para a consolidação do yaoi como um mangá “escrito por mulheres para mulheres”. Sua principal especificidade está no tema: o romance entre homens. O uso do tema homoerótico masculino desponta como expressão feminina, subvertendo as hierarquias sociais de uma sociedade marcada pelo machismo. As mulheres japonesas passam a utilizar a relação homoerótica como a*espaço expressivo para suas vozes abafadas, apoiando-se na equidade hierárquica entre os parceiros.

The potential effects of spaceflight on the processes of mammalian fertilizaton, implantation and embryonic development are investigated. Five female and two male rats were placed together on Day 2 of the flight. By R+17, it was determined that both flight and synchronous females were not carrying normal pregnancies and three of the flight animals were laparotomized. The uterus and ovaries were processed for microscopic analyses. The two remaining flight females were allowed to recover from the exploratory operation, rebred with flight males and delivered normal litters. As a control for potential transplacental effects that might be interpreted as direct spaceflight effects, a series of fertilized Japanese quail (Coturnix japonica) eggs was flown on Cosmos 1129. Although all of the eggs were adversely impacted by an inflight failure of the incubator humidifier on flight Day 13, several embryos were able to progress to a developmental stage equivalent to that of a control 10-12 Day embryo.

1989-01-01

Steroid autoradiography and systematic and intracranial steroid treatment were undertaken to determine the neuroanatomical loci which are sufficient to activate steroid sensitive behaviors in the Japanese quail. (1) Autoradiographic localization of steroid binding cells was performed on male and female quail brains using tritiated ( 3 H) testosterone (T), estradiol (E2), or 5α-dihydrotestosterone (DHT). The distributions of labelled cells in the quail brain following 3 H-T or 3 H-E2 injection and autoradiography were similar to one another. The distribution of labelled cells following 3 H-DHT autoradiography was limited in comparison to that following 3 H-T autoradiography. Males were found to have more labelled cells than females in nucleus taeniae. (2) Intracranial implantation of minute pellets of testoterone propionate (TP) and estradiol benzoate (EB) was performed to determine neuroanatomical loci at which steroids activate sexual behavior. Both TP and EB implants in the preoptic area (POA) activated male copulatory behavior. (3) Systematic injection of aromatase inhibitor prior to and concurrent with implantation completely blocked copulatory behavior in males with TP implants in the POA but failed to block copulation in males with EB implants in the POA. (4) Intact males and castrated males given 5 dosages of systematic EB treatment were tested for sexual behavior, and blood samples from each group were assayed for E2 concentration. (5) Midbrain DHTP implants were activated crowing without significantly stimulating peripheral androgen-sensitive tissues, but the effect on crowing was not localized to any one nucleus

Instituições e desenvolvimento no Japão: modelo de capitalismo, trajetória pós 1990, desafios atuais

Full Text Available Resumo O objeto principal do artigo é a mudança de trajetória do capitalismo japonês, procurando entender por que um modelo tão bem-sucedido nas décadas de 1950 a 1980 passou a enfrentar sérias dificuldades a partir dos anos 1990. Para isso, trabalha a interação entre fatores institucionais, econômicos e políticos, dando atenção especial às instituições típicas do capitalismo japonês, incluindo as relações de trabalho, a governança corporativa, a organização do sistema financeiro e o papel do Estado. Procura-se destacar o papel que essas instituições tiveram na fase de prosperidade e também as pressões que passaram a sofrem a partir das mudanças domésticas e internacionais. Um aspecto central é interpretar até que ponto o modelo japonês continua distintivo, preservando as características de um “modelo de capitalismo coordenado”. O artigo adota um enfoque de economia política centrado nas teorias do institucionalismo histórico e das variedades de capitalismo. Essas teorias, ao mostrar como as instituições nacionais condicionam o padrão de resposta, fornecem um invólucro para interpretar as mudanças, ampliando a compreensão das interações entre economia, política e instituições. A partir do referencial mais geral, o artigo incorpora também teorias mais específicas voltadas a interpretar a crise econômica e alguns desafios enfrentados pela economia japonesa. O artigo mostra que o Japão vem passando por muitas mudanças institucionais, mas vem também preservando aspectos distintivos do modelo tradicional japonês, com a constituição de um modelo híbrido. Além dos problemas macroeconômicos, ligados à insuficiência de demanda efetiva, ao envelhecimento da população e aos desafios fiscais, há também muitos desafios sociais e políticos, que incluem a forte dualidade no mercado de trabalho e as dificuldades enfrentadas por jovens e mulheres. Em face de todas essas questões, o sistema pol

The anabolic steroid 17β trenbolone (17β-TB), a known endocrine disrupting chemical, may influence reproductive functions in avian wildlife. We evaluated the effects of dietary exposure to 17β-TB at 5 and 20 ppm on reproductive functional endpoints in Japanese quail during and after sexual maturation. In the male, 5 and 20 ppm treatments revealed no differences in body and testes weight, testes histology, plasma testosterone concentrations, or size and weight of the foam glands. However, the onset of foam production was significantly earlier (days of age) in the 20 ppm males. In females, dietary 17β-TB at 20 ppm caused a reduction in the number of maturing yellow yolk follicles and overall egg production. Plasma testosterone concentrations were reduced compared to controls. Histology of the oviductal sperm storage tubules was normal in all treatments. The number of sperm holes, sites on the perivitelline layer (PVL) where sperm bound and hydrolyzed a path through the PVL, was significantly greater in the 10th egg laid compared to the 1st egg laid in the 20 ppm treatment. Potential effects, albeit transient, on endpoints associated with male maturation warrant further investigation into the sensitivity of these measures in the event of embryonic and/or trans-generational exposure to 17β-TB.

Screening for acyanogenic somatic mutations in cassava (Manihot esculenta Crantz)

Moh, C.C.

1976-01-01

By irradiating the young stem cuttings (6-8 months old wood) of a cassava cultivar, Japonesa, (Manihot esculenta Crantz) with an acute dose of 4 kR from a 60 CO source, it was found that in a number of cases, the induced mutant characters appeared in the whole R 1 plants or in large chimeric sectors. This result suggested that a cassava plant could develop from one or two initial cells in the shoot apex of a bud. This unusual biological response to radiation provides a great advantage for selection in mutation breeding. By using the sodium picrate method, 2676 leaves from 1338 R 1 plants irradiated with 4 kR were screened for hydrocyanic acid content (HCN). As compared with the control, some leaves had higher and some had lower HCN level, indicating that the radiation broadened the variability. Whether or not those R 1 plants producing a lower level of HCN in the leaves are truly a genetic mutant cannot be ascertained at present. Further screening of the selected R 1 plants in the subsequent vegetative propagation generations will help to distinguish whether they are genetic mutants. (author)

Effects of ambient temperature on the acute oral toxicity of parathion were investigated in Japanese quail (Coturnix japonica) maintained at thermoneutral temperature (26.degree. C) or exposed to elevated (37.degree. C) or reduced (4.degree. C) temperatures commonly encountered by free-ranging wild birds. Based upon estimates of the median lethal dosage, there was up to a two-fold enhancement of parathion toxicity in birds chronically exposed to heat or cold. Twenty-four hours after administration of a low dosage (4 mg/kg body wt, po), there was markedly greater cholinesterase inhibition in surviving heat-exposed quail compared with those reared at 26.degree. C (e.g., brain acetylcholinesterase depression of 42% versus 12%). There were no differences in hepatic activities of parathion oxidase, paraoxonase, or paraoxon deethylase which could account for greater toxicity to chronically heat-exposed birds. In contrast, 4 mg parathion/kg wt elicited less plasma cholinesterase inhibition in cold-exposed quail compared to thermoneutral controls (e.g., birds is substantially influenced by environmental temperature.

Full Text Available This study seeks to reconcile two issues, totally opposite a priori: religion and videogames. One of the most turbulent fields of biblical studies is the apocryphal literature, and within it, the apocalyptic genre is the most developed, with the Ethiopic Book of Enoch to the head. This work has puzzled investigators over the years due to the intriguing figure of his protagonist and issues such as the origin of evil, the transmission of knowledge, angels and demons. Therefore, it is not surprising that the work has come to interest people outside the Judeo-Christian culture. El Shaddai: Ascension of the Metatron is the biggest example of this, a Japanese version of this Jewish work, leaving the literary field to get into videogames.

Full Text Available The objective of the study was to observe the effect of experimental hypodynamy simulating weightlessness in space on the structure, ultrastructure and alkaline phosphatase activity of kidney in Japanese quail (Coturnix coturnix japonica. Two days after hatching, the quails were suspended in special shirts below the cage ceiling so their feet did not touch the floor. They could consume food and water ad libitum. Experimental animals were sacrificed after 14, 21, 28, 35, 42, 49 and 56 days of hypodynamy. Birds of the same age, hatched at the same time, and fed the same diet were used as a control. Samples of kidney were processed for light (LM and transmission electron microscopy (TEM, and alkaline phosphatase (AP analysis. Short-term (14–28 days hypodynamy caused no marked damage to the structure and ultrastructure of kidneys. However, after long-term (35–59 days hypodynamy, morphological changes were observed in some cells of the proximal and distal tubules. The dying cells in proximal tubules, observed in semi-thin sections by LM, were dark and contained a nucleus of irregular shape. Observation by TEM showed that their nucleus was dark and shrivelled and the electron-dense cytoplasm contained long, dense, rod-shaped mitochondria with thin mitochondrial cristae. Microvilli were present on the apical surface of cells and formed a brush border. Sporadic dying cells were also observed in distal tubules. Large, light vacuoles were found in the cytoplasm of cells of collecting tubules, however, the structure of renal corpuscles and medullary loops remained undisturbed. Microscopical analysis by means of a direct TUNEL reaction on days 35 to 59 of hypodynamy showed a moderate occurrence of cellular apoptosis in the proximal and distal tubules of experimental Japanese quail. The activity of AP in the brush border of the proximal tubules on days 14–29 of hypodynamy was normal in experimental animals and showed no significant differences in

An experiment was conducted to evaluate egg quality and ultrastuctural measurements of eggshell using a Scanning Electron Microscope (SEM) in 2 lines (selected and control) of Japanese quail. A selection program was applied over 22 consecutive generations for higher egg production and lower broken egg percentage. The results revealed that the females of the selected line produced significantly (P < 0.01) higher egg mass compared to that of the control line. Also, the selection procedure significantly improved feed conversion ratio. The eggshells of the selected line had a higher breaking strength compared to those of the control line, although there was no difference between them in shell thickness. Significantly higher wet (P < 0.01) and dry (P < 0.05) eggshell percentages were found in the selected line. In general, the eggshells of the selected line had a lower total score (good) of ultrastructural evaluation compared to the control line. According to scanning electron microscope data, the incidence of certain structural variants was more common in eggshells of the control line suggesting poor shell strength. The incidence of alignment was more prevalent in control eggshells compared to selected ones, suggesting lower resistance to breakage. Late fusion and large interstitial spaces of the palisade layer indicating decreased resistance to fracture were observed in control eggshells. It could be concluded that the improvement eggshell quality may be caused by the long-term selection for lower cracked and broken egg rates from generation to generation. © 2016 Poultry Science Association Inc.

Behavioral and neuropharmacological evidence that serotonin crosses the blood-brain barrier in Coturnix japonica (Galliformes; Aves

Full Text Available This study was carried out aiming to reach behavioral and neuropharmacological evidence of the permeability of the blood-brain barrier (BBB to serotonin systemically administered in quails. Serotonin injected by a parenteral route (250-1000 µg.kg-1, sc elicited a sequence of behavioral events concerned with a sleeping-like state. Sleeping-like behaviors began with feather bristling, rapid oral movements, blinking and finally crouching and closure of the eyes. Previous administration of 5-HT2C antagonist, LY53857 (3 mg.kg-1, sc reduced the episodes of feather bristling and rapid oral movements significantly but without altering the frequency of blinking and closure of the eyes. Treatment with the 5-HT2A/2C antagonist, ketanserin (3 mg.kg-1, sc did not affect any of the responses evoked by the serotonin. Quipazine (5 mg.kg-1, sc a 5-HT2A/2C/3 agonist induced intense hypomotility, long periods of yawning-like and sleeping-like states. Previous ketanserin suppressed gaping responses and reduced hypomotility, rapid oral movements and bristling but was ineffective for remaining responses induced by quipazine. Results showed that unlike mammals, serotonin permeates the BBB and activates hypnogenic mechanisms in quails. Studies using serotoninergic agonist and antagonists have disclosed that among the actions of the serotonin, feather bristling, rapid oral movements and yawning-like state originated from activation of 5-HT2 receptors while blinking and closure of the eyes possibly require other subtypes of receptors.

High Yolk Testosterone Transfer Is Associated with an Increased Female Metabolic Rate.

2016-01-01

Yolk androgens of maternal origin are important mediators of prenatal maternal effects. Although in many species short-term benefits of exposure to high yolk androgen concentrations for the offspring have been observed, females differ substantially in the amount of androgens they transfer to their eggs. It suggests that costs for the offspring or the mother constrain the evolution of maternal hormone transfer. However, to date, the nature of these costs remains poorly understood. Unlike most previous work that focused on potential costs for the offspring, we here investigated whether high yolk testosterone transfer is associated with metabolic costs (i.e., a higher metabolic rate) for the mother. We show that Japanese quail (Coturnix japonica) females that deposit higher testosterone concentrations into their eggs have a higher resting metabolic rate. Because a higher metabolic rate is often associated with a shorter life span, this relationship may explain the negative association between yolk testosterone transfer and female longevity observed in the wild. Our results suggest that metabolic costs for the mother can balance the short-term benefits of yolk testosterone exposure for the offspring, thereby contributing to the maintenance of variation in maternal yolk hormone transfer in natural populations.

The implementation of uniform organization methods in diverse workplace contexts, regardless of local cultural patterns, may result in the imposition of foreign work concepts and views on workplace relations, cognitive processes, the company's hierarchy, etc. If the encounter between the International and the local is not handled with enough care, tensions and conflicts might ensue that could hinder the company's performance. The author gives the example of Suzuki Corporation and its affiliated Santana Motor in the town of Linares, province of Jaén, Spain.En un mundo cada vez más globalizado, las firmas transnacionales tienden a introducir importantes cambios en sus empresas filiales, incluidos los que afectan a la dimensión cultural. La aplicación de sus métodos organizativos sobre los diversos contextos socioculturales, ignorando los patrones culturales locales, puede conducir a la imposición de unos nuevos conceptos laborales, una visión diferente de las relaciones socioculturales, de los procesos cognitivos, de la estructura jerárquica, etc. Si esta dinámica de entrecruzamiento entre valores foráneos y autóctonos no se lleva a efecto con la suficiente precaución, el proceso de intersección podría originar no pocas fricciones y conflictos que podrían poner en peligro la marcha de la compañía. Este artículo se centra en el caso particular de la Suzuki Corporation y su filial andaluza, Santana Motor, en la ciudad jiennense de Linares.

Effects of gamma irradiation on histomorphology of some endocrine glands of the rain quail, Coturnix coromandelica (Gmelin)

Deshmukh, B.D.; Suryawanshi, S.A.

1989-01-01

Effects of single, whole-body 60 Co-gamma irradiation in different doses (250 rad to 15 k rad) on histology of thyroid, adrenal and pancreatic islets of the rain quail were studied. A low dose of 250 rad failed to evoke any change in histology of the glands studied. Doses of 500 rad and 1 k rad resulted in hypoactivity of thyroid but could not affect adrenal and pancreatic islets. Exposure to 1.5 k rad and higher doses caused hyperplasia and hypertrophy of thyroid and hypertrophy of adrenal gland. Thyroid was injured by heavy irradiation. Doses up to 3 k rad did not bring about any change in islet cells, however, higher doses resulted in degenerative changes in islet cells. α-islets were affected by 7 and 15 k rad but necrotic changes in β-islets were observed only after exposure to 15 k rad. The results indicate that thyroid is the most sensitive and pancreatic islet, highly resistant to gamma radiation. (author). 20 refs., 4 figs

A Hi-Vision do Japão: mudança de paradigma técnico ou estético?

Full Text Available No Japão, a transmissão em HDTV tem uma história de quase quatro décadas com a criação de uma tecnologia chamada Hi-Vision e seu sistema MUSE, que apresenta pequenas diferenças em relação aos outros dois sistemas mundiais, o europeu, HD-MAC, e o americano, ATV. O que tem mais visibilidade nesse campo é o fato de que a HDTV traz em si paradigmas técnicos que mexem com a qualidade da imagem. O que não se vê muito, no entanto, é o alinhamento entre os paradigmas técnicos e estéticos. Isto é, fatos que mostrem mudanças na linguagem da programação de televisão trazidas pela mudança tecnológica. Por isso, o que faço neste texto não é simplesmente destacar a tecnologia de HDTV desenvolvida pelo Japão, e sim entender o casamento entre técnicae estética na geração do produto televisivo. Ou seja, a partir de um programa gerado pela NHK, rede pública de televisão japonesa, abordo a influência dessa nova tecnologia na criação artí­stica e técnica de TV. Tomando mão das teorias da semiótica da cultura, pensada a partir dos pressupostos da Escola de Tártu, verifico se há e onde há processos que podem ser entendidos como sistema modelizante e em que modelos artí­sticos da cultura japonesa eles se apóiam.Abstract: In Japan, the transmission in HDTV has a history of almost four decades, with the creation of a technology termed Hi-Vision, and its MUSE system, which presents small differences in relation to another two world systems, the European, HD-MAC, and the American, ATV.

What is not commonly found, however, is the alignment between the technical and aesthetic paradigms, that is, facts that show changes in the language of television programs brought by the technological change. For that reason, what I do in this text is not to simply highlight the technology of HDTV

NUTRITIONAL ENHANCEMENT OF ALFALFA THROUGH GENETIC ENGINEERING

Full Text Available Alfalfa (Medicago sativa L. is a pasture legume crop of primary importance to animal production throughout the world. The nutritional quality of alfalfa, as of other leguminous forage crops, is mainly determined by their content in selected essential amino acids (EAAs, such as methionine (Met and cysteine (Cys. In alfalfa, however, these S-containing amino acids constitute only about 1% or less of crude proteins (Frame et al., 1998. This is significantly less than the 3.5% Met+Cys content in the recommended FAO reference protein (FAO, 1973. Recent advances in genetic engineering allow to use the transgenic approach to increase the content of specific essential amino acids in target plant species. A number of different molecular approaches have been developed to address this issue, such as over-expression of a heterologous or homologous Met-rich protein, expression of a synthetic protein, modification of protein sequence, and metabolic engineering of the free amino acid pool and protein sink. To study the possibility of transgenic enhancement of nutritional quality of alfalfa, we used the approach of expression of a heterologous protein rich in Met+Cys in cells of alfalfa. The T-DNA introduced into the genome of alfalfa, using Agrobacterium tumefaciens-mediated genetic transformation, contained the selectable merker gene nptII for kanamycin (Kn resistance, and a cDNA of Ov gene from Japanese quail (Coturnix coturnix coding for a high Met+Cys containing ovalbumine (Mucha et al., 1991, both under constitutive promoters. After cocultivation of petiole segment- and leaf blade-explants of two highly embryogenic alfalfa genotypes Rg9/I-14-22 and Rg11/I-10-68 (Faragó et al., 1997 with cells of A. tumefaciens strain AGL1 carrying the nptII and Ov genes, and selection of transgenic cells on Kn containing selective media, more than one hundred putatively transgenic regenerants were obtained through somatic embryogenesis.

Disentangling Genetic and Prenatal Maternal Effects on Offspring Size and Survival.

Organizational processes during prenatal development can have long-term effects on an individual's phenotype. Because these early developmental stages are sensitive to environmental influences, mothers are in a unique position to alter their offspring's phenotype by differentially allocating resources to their developing young. However, such prenatal maternal effects are difficult to disentangle from other forms of parental care, additive genetic effects, and/or other forms of maternal inheritance, hampering our understanding of their evolutionary consequences. Here we used divergent selection lines for high and low prenatal maternal investment and their reciprocal line crosses in a precocial bird-the Japanese quail (Coturnix japonica)-to quantify the relative importance of genes and prenatal maternal effects in shaping offspring phenotype. Maternal but not paternal origin strongly affected offspring body size and survival throughout development. Although the effects of maternal egg investment faded over time, they were large at key life stages. Additionally, there was evidence for other forms of maternal inheritance affecting offspring phenotype at later stages of development. Our study is among the first to successfully disentangle prenatal maternal effects from all other sources of confounding variation and highlights the important role of prenatal maternal provisioning in shaping offspring traits closely linked to fitness.

Egg-laying substrate selection for optimal camouflage by quail.

Camouflage is conferred by background matching and disruption, which are both affected by microhabitat. However, microhabitat selection that enhances camouflage has only been demonstrated in species with discrete phenotypic morphs. For most animals, phenotypic variation is continuous; here we explore whether such individuals can select microhabitats to best exploit camouflage. We use substrate selection in a ground-nesting bird (Japanese quail, Coturnix japonica). For such species, threat from visual predators is high and egg appearance shows strong between-female variation. In quail, variation in appearance is particularly obvious in the amount of dark maculation on the light-colored shell. When given a choice, birds consistently selected laying substrates that made visual detection of their egg outline most challenging. However, the strategy for maximizing camouflage varied with the degree of egg maculation. Females laying heavily maculated eggs selected the substrate that more closely matched egg maculation color properties, leading to camouflage through disruptive coloration. For lightly maculated eggs, females chose a substrate that best matched their egg background coloration, suggesting background matching. Our results show that quail "know" their individual egg patterning and seek out a nest position that provides most effective camouflage for their individual phenotype. Copyright © 2013 Elsevier Ltd.

One of the basic steps in objective analysis of sperm motility is the subdivision of a motile sperm population into slow, medium and rapid categories based on their velocity. However, for CASA analysis of quail sperm, the velocity values for categorization of slow, medium and rapid sperm have not yet been standardized. To identify the cut-off values of "velocity curvilinear" (VCL) for quail sperm categorization, we captured and analysed 22,300 tracks of quail sperm using SCA ® -CASA. The median and mean VCL values were 85 and 97 μm/s. To define the VCL cut-off values, we used two methods. In the first, we identified the upper (rapid sperm) and lower (slow sperm) cut-off values using: (i) median VCL ± 25% or ± 50% or ± 75% of median VCL value; (ii) first and third quartile values of VCL data (i.e. 25% cut-off setting); and (iii) 33% and 66% of VCL data. Among these settings, sperm categories and their corresponding motility characteristics recorded using the "25%" setting (i.e. slow ≤36 ≤ medium ≤154 ≤ rapid) were found the most realistic and coherent with male ranking by fertility. In the second method, we calculated heteroscedasticity in the total VCL data using PCA and the two-step clustering method. With this approach, the mean of the high and low clusters was 165 and 51 μm/s, respectively. Together, the mean from two methods suggested that, for SCA ® -CASA categorization of quail sperm, sperm should be classed as "rapid" at VCL ≥160 μm/s and "slow" at VCL ≤45 μm/s. © 2017 Blackwell Verlag GmbH.

Full Text Available La casa de Halldor Gunnløgsson, una de las obras más refinadas de la Edad de Oro de la arquitectura moderna danesa, es el resultado de una fuerte voluntad y disciplina artística personal. La cubierta plana, suspendida sobre una gran plataforma pavimentada –que continúa la construcción del lugar– tiene una gran presencia. En el interior, un espacio único, fluye libremente y se extiende al paisaje. Hay una extraordinaria sofisticación de la construcción vernácula; y una fuerte conexión con la arquitectura tradicional japonesa, revelada por el deseo de vivir en estrecho contacto con la naturaleza, la búsqueda del refinamiento mediante la moderación, la eliminación de los elementos superfluos y la preocupación por la luz y la sombra –estableciéndose un paralelismo con el oscuro invierno nórdico. Su característica abstracción es un ejemplo de modernidad. El edificio se acerca a la belleza clásica, por la aparición de proporción, simetría y orden, pero también por el tratamiento suave de las superficies de los materiales. Se reconoce un ritmo en diferentes dimensiones. Se valora la escala. Los colores aplicados o inherentes al material, alcanzan intensidad. La experiencia del espacio arquitectónico es global. Es una casa mágica y maravillosa.

O CAMINHO DA NEGATIVIDADE ENTRE OCIDENTE E ORIENTE: A RECEPÇÃO CONTEMPORÂNEA DE MESTRE ECKHART EM KEIJI NISHITANI

Full Text Available O diálogo entre Ocidente e Oriente faz parte da mais recente história da filosofia contemporânea. Frente aos esforços de apresentar o Budismo japonês aos ocidentais, Teitarō Suzuki, chamado Daisetsu, comentou que, dentre os pensadores da filosofia ocidental, “Eckhart é aquele que está guiando o Zen para dentro do Ocidente”. O interesse da filosofia japonesa contemporânea por Mestre Eckhart, sobretudo dentre os autores da chamada Escola de Kyōto, representa não apenas uma mera aproximação por empatia, mas uma profunda introspecção da mística medieval como possibilidade de manifestar filosoficamente as bases do Zen Budismo, abrindo caminho para uma interculturalidade filosófica inédita no século XX. A despeito de sua presença constante (por vezes explícita, por vezes implícitas em diversos filósofos japoneses contemporâneos, foi Keiji Nishitani o pensador que com maior devoção refletiu sobre a obra de Eckhart. A partir desse diálogo, talvez seja possível investigar até que ponto uma recepção contemporânea de Mestre Eckhart possa porventura reverberar uma meditação pertinente aos problemas cotidianos do século XXI e este é, sem embargo, o intuito deste trabalho.

Full Text Available La casa de invitados de Niels Bohr fue el primer edificio del arquitecto danés Vilhelm Wohlert (1920-2007. Arraigado a la tradición danesa, representa una renovación basada en la absorción de influencias extranjeras: la arquitectura americana y la tradición japonesa. La caja de madera tiene el carácter sensible de un organismo vivo, siempre cambiante según las variaciones de luz del día o temperatura. Puertas plegables y contraventanas generan extensiones de las habitaciones. Cuando se abren, crean una prolongación del espacio interior, que se extiende a la naturaleza circundante, y se expande hacia el espacio exterior, permitiendo su movilización. Se establece una arquitectura de flujos. Protagoniza un ejemplo de la modernidad como refinamiento en la técnica de los límites y la idea de que la arquitectura no es un objeto material, sino el espacio generado en su interior. Podría ser visto como un ikebana; “el arte del espacio”, donde se produce una circulación de aire entre sus componentes; algo vivo que expresa la tercera dimensión, el equilibrio asimétrico, un interés por la materia, su textura y efecto emocional que emana. Hay armonía y equilibrio, que transmiten serenidad y belleza; un encuentro con la naturaleza; un mundo de relaciones amable al ser humano.

Arquitecturas reversibles de Japón. Las casas de Shirakawa-go

Paula Jaén Caparrós

2017-04-01

Full Text Available “Minka” significa literalmente “casas de la gente” en japonés, y se refiere a la casa tradicional japonesa construida fundamentalmente desde las épocas más antiguas hasta finales del siglo XIX. Se trata de construcciones sencillas y ligeras hechas habitualmente con elementos de madera, bambú, y paja, unidos por juntas de madera y cuerdas. Las regiones montañosas de Shirakawa-go y Gokayama, en la zona central de Japón, al Oeste de Tokio, permanecieron aisladas durante un largo periodo de tiempo. Como consecuencia de ello, allí se desarrolló un tipo específico de minka, las llamadas Gassho-zukuri, caracterizadas por el uso de un sistema extremadamente lógico y racional en su construcción resultado de una adaptación natural a las difíciles condiciones del entorno. Construidas como estructuras permanentes, estas casas tradicionales son sin embargo desmontables: sus distintos componentes permiten ser desarmados, recuperados y ensamblados de nuevo sin mayor dificultad. El alto potencial de desmontaje contenido en estas pequeñas construcciones invita a reflexionar acerca de las pautas proyectuales y constructivas presentes en sus soluciones que podrían ser recuperadas y aplicadas en propuestas actuales que integraran el desmontaje, la recuperación y el traslado de todo el objeto construido como factor clave para un diseño arquitectónico sostenible.

Y por último, en el capítulo siete del anime Kanamemo (2009, se estudió el ritual de conmemoración de los muertos a través de la celebración del Obon, una costumbre de origen budista que se ha arraigado en la cultura japonesa. Se realiza un análisis comparativo en búsqueda de regularidades y rupturas que den cuenta del entramado de relaciones e influencias culturales, políticas, religiosas y el papel de las industrias culturales en las representaciones de la muerte.

Full Text Available Filiación, o el compartir de un legado de generación a generación, es más evidente al considerar los principios específicos de la arquitectura. Este artículo examina cómo el legado de Le Corbusier fue transmitido a Reiko Hayama, mujer japonesa, pionera en arquitectura, y quien desde 1959 a 1965, forjó su carrera en Tokio trabajando para Kunio Maekawa, uno de los previos colaboradores “del Maestro” de la Rue de Sèvres 35. Posteriormente, decidió mudarse a París y trabajar para Charlotte Perriand y Jean Prouvé, previo a establecer su propio estudio de trabajo en los años 1976 a 2013. Este artículo se centra en las repercusiones del patrimonio de Le Corbusier en la práctica personal de Hayama. Sus reflexiones señalan que Maekawa y Prouvé le dieron paso a un camino que se situaba por fuera de los principios de Le Corbusier, entre los cuales se encuentran: una preocupación ética por el medio ambiente; un proceso en el diseño que deliberadamente tuvo en cuenta un contexto cultural y una forma arquitectónica derivada de un proceso tecnológico de razonamiento. El patrimonio del Modulor fue directamente asumido por Hayama, siendo este una herramienta operativa de suma importancia en la metodología Le Corbusiana.

Nucleoli are the product of nucleolus organizing region activity (NOR) of specific chromosomes. Their basic function is to synthetise ribosomal RNA precursors and promote the maturation and assemblage of preribosomal RNP molecules. Information on rRNA-coding gene activity can be provided by the analysis of the number and size of nucleoli in the prophase of the first meiotic division. The morphology and ultrastructure of a nucleolus depends, among others, on the species and cell growth cycle as well as the physiological and pathological state of an organism. The purpose of this research was to determine the number and size of nucleoli in the spermatocytes of the domestic chicken and the Japanese quail. Diverse numbers and sizes of nucleoli in the cells of the analysed birds were observed. 1-4 nucleoli were identified in chicken cells (1.91 +/- 0.63 on average) and 1-2 in quail cells (1.13 +/- 0.33 on average). For the total of 957 nucleoli observed in Gallus cells, 329 were classified as large and 628 as small. In Coturnix cells, 563 nucleoli were identified (66 large and 497 small ones). An analysis of the numbers and sizes of nucleoli can be performed at the cytogenetic level and serve as an alternative source of information on rRNA encoding gene and nucleolus organising region (NOR) activities.

Japanese quail (Coturnix c. japonica) were fed 0, 8, 16 or 32 p.p.m. of mercury as mercuric chloride from 3 days of age through 20 weeks of age. The onset of egg production generally occurred earlier for hens fed HgCl2. Average age in days at first oviposition for the control, 8 p.p.m., 16 p.p.m. and 32 p.p.m. was 48.4, 50.9, 46.9 and 44.0 respectively. The average rate of egg productivity from first oviposition to attainment of full growth (9 weeks of age) correlated positively with in increased dietary mercury (controls, 8 p.p.m., 16 p.p.m., 32 p.p.m. ? 75.2, 69.3, 86.1 and 93.3% respectively). By 20 weeks of age productivity was 81.0, 80.6, 87.5 and 92.9% for control, 8, 16 and 32 p.p.m. groups respectively. Fertility was depressed when hens were fed HgCl2. At 9 weeks of age average control fertility was 59% contrasted with 25% for the 32 p.p.m. group. At 12 weeks fertility increased to 89% and 57% for these groups. From this study it is apparent. that the onset and rate of egg production was stimulated by HgCl2, but fertility was adversely affected.

Full Text Available Experimentos com ninhos artificiais são utilizados para testar hipóteses ecológicas e comportamentais que influenciam na predação de ninhos naturais. O tamanho do ovo, a textura da casca e a cor podem influenciar na taxa de predação, porém poucos estudos avaliam qual modelo de ovo é o mais adequado para simular a predação de ninhos em áreas tropicais. O objetivo deste trabalho foi comparar a predação de diferentes modelos de ovos (ovos de codorna, massa de modelar e canários no solo e a 1,30 m de altura no sub-bosque. O experimento foi realizado Ilha Anchieta, Ubatuba, São Paulo, Brasil. Foi encontrada uma diferença significativa na taxa de predação entre os ovos de codorna (71,87% e sintéticos (93,75% e entre os ovos de codorna e de canário (100% no solo. Entretanto, não houve diferença significativa entre os ovos sintéticos e de canário. Os ninhos no sub-bosque apresentaram um padrão diferenciado do solo quando se refere aos ovos de codorna (25% e sintéticos (28,1%, mas houve diferenças significativas quando os ovos de canário foram comparados com os ovos sintéticos e de codorna. Nosso trabalho demonstrou que diferentes tipos de ovos sobre uma mesma pressão de mesopredadores apresentaram taxas de predação diferentes. Portanto, estudos que avaliam o sucesso reprodutivo da avifauna baseado na predação de ninhos artificiais devem considerar a utilização de diferentes tipos de ovos e estratos na vegetação.Experiments on artificial nests are usually used to test ecological hypothesis and behavioural that affects the predation of natural bird nests.

Biological data on PCBs in animals other than man

Stickel, L.F.

SUMMARY: Polychlorinated biphenyls have become ubiquitous in the world ecosystem in quantities similar to those of DDE. Experimental studies have shown that PCBs have a toxicity to mallards, pheasants, bobwhite quail, coturnix quail, red-winged blackbirds, starlings, cowbirds, and grackles that is of the same order as the toxicity of DDE to these species. Overt signs of poisoning also are similar to those caused by compounds of the DDT group. Toxic effects of DDE and Aroclor 1254 to coturnix chicks were additive, but not synergistic. PCBs containing higher percentages of chlorine are more toxic to birds than those containing lower percentages. PCBs of foreign manufacture contained contaminants to an extent that greatly increased their toxicity. Residues of PCBs in the brains of birds killed by these compounds measure in the hundreds of parts per million. PCBs may have contributed to mortality of some birds in the field. Toxicity to insects of PCBs of different degrees of chlorination is the reverse of the pattern in birds: the lower chlorinations are more toxic to insects. PCBs enhanced the toxicity of dieldrin and DDT to insects. Shrimp are very sensitive to PCBs and most will die as a result of 20-day exposure to a concentration of 5 ppb. PCBs also inhibit shell growth of oysters. Crabs are less sensitive; all accumulate residues to many times the concentrations in the water, and a test with crabs showed that they lost the residues very slowly. Growth of certain species of marine diatoms was experimentally inhibited by PCBs, but algae were not affected. The small marine crustacean, Gammarus, is sensitive to PCBs in concentrations of thousandths to tenths of a part per billion. Exposure to 5 ppb of Aroclor 1254 caused mortality of two species of fish in 14-45 days. Onset of death was delayed and was accompanied by fungus-like lesions. Rainbow trout were quickly killed by terphenyls at 10 ppb under normal oxygen conditions and at 2 ppb with reduced oxygen

Late Pleistocene (23,000-10,000 14 C yr BP) and Holocene (10,000 14 C yr - present BP) avifaunas are described from the Henry Lambert and associated passages in Gardners Gut Cave, Waitomo Caves, North Island, New Zealand. Nine radiocarbon dates on bones and three uranium series dates on speleothems support the dating of the sites. These data are augmented by six new dates and reanalysis of the avifaunas from F1c Cave, also in the Waitomo karst. A distinctive Pleistocene avifauna characterised by the moa Euryapterix curtus and Pachyornis mappini and the North Island goose (Cnemiornis gracilis) with common associates including New Zealand coot (Fulica prisca), North Island takahe (Porphyrio mantelli), Finsch's duck (Euryanas finschi), and North Island kokako (Callaeas wilsoni) was present. The presence of kokako, saddleback (Philesturnus rufusater), and robin (Petroica longipes) in the Pleistocene deposits and the absence of grassland taxa such as pipit (Anthus noveaseelandiae) and quail (Coturnix novaezelandiae) indicate that the vegetation about Gardners Gut Cave included tall shrubland and probably lacked much grassland, even over the Last Glacial Maximum. The Holocene at Waitomo was characterised by a moa fauna dominated by Anomalopteryx didiformis, although both Euryapteryx curtus and Pachyornis mappini persisted in small numbers. The frequent occurrence of kakapo (Strigops habroptilus), weka (Gallirallus australis), and brown teal (Anas chlorotis) typifies Holocene avifaunas; Cnemiornis and Fulica are unknown from Holocene deposits in the area.

The effects of testosterone on immune function in quail selected for divergent plasma corticosterone response.

2009-10-01

The immunocompetence handicap hypothesis (ICHH) suggests that the male sex hormone testosterone has a dual effect; it controls the development and expression of male sexually selected signals, and it suppresses the immune system. Therefore only high quality males are able to fully express secondary sexual traits because only they can tolerate the immunosuppressive qualities of testosterone. A modified version of the ICHH suggests that testosterone causes immunosuppression indirectly by increasing the stress hormone corticosterone (CORT). Lines of Japanese quail (Coturnix japonica) selected for divergent responses in levels of plasma CORT were used to test these hypotheses. Within each CORT response line (as well as in a control stock) we manipulated levels of testosterone in castrated quail by treatment with zero (sham), low or high testosterone implants, before testing the birds' humoral immunity and phytohaemagglutinin (PHA)-induced immune response, as well as body condition. The PHA-induced response was not significantly affected by CORT selected line, testosterone treatment or their interaction. There was, however, a significant effect of CORT line on humoral immunity in that the control birds exhibited the greatest antibody production, but there was no significant effect of testosterone manipulation on humoral immunity. The males in the sham implant treatment group had significantly greater mass than the males in the high testosterone group, suggesting a negative effect of high testosterone on general body condition. We discuss these results in the context of current hypotheses in the field of sexual selection.

We investigated the effects of the androgenic growth promoter 17β-trenbolone (17βTB) on adult Japanese quail (Coturnix japonica) exposed across three generations. The F0 generation was exposed after sexual maturity to 0, 1, 5, 10, 20, and 40 ppm through feed. The F1 generation was exposed in ovo by maternal transfer and through feed at the same doses as their parents. The F2 generation was exposed in ovo only. Levels of plasma sex steroids, gonadal Cytochrome P450 aromatase (CYP19A1) mRNA and select brain neuroendocrine peptide mRNAs were measured. In males, testosterone levels did not differ in any generation from those in controls. Estradiol was significantly elevated in 17βTB treated F0 and F1 males. In F0 and F1 females, testosterone was suppressed by 17βTB, whereas estradiol was significantly higher at 40 ppm in F0 and at 10 ppm in F1 females. CYP19A1 expression in F1 males and females increased suggesting a compensatory response to the androgenic effects of 17βTB. Few significant effects were observed in the F2 birds indicating that in ovo exposure had limited effects on the monitored endpoints. Overall, our results confirmed endocrine disrupting effects of dietary 17βTB in Japanese quail but the response was dependent on sex, developmental stage at initiation of exposure, and dose.

In search of genetic constraints limiting the evolution of egg size: direct and correlated responses to artificial selection on a prenatal maternal effector.

Maternal effects are an important force in nature, but the evolutionary dynamics of the traits that cause them are not well understood. Egg size is known to be a key mediator of prenatal maternal effects with an established genetic basis. In contrast to theoretical expectations for fitness-related traits, there is a large amount of additive genetic variation in egg size observed in natural populations. One possible mechanism for the maintenance of this variation is through genetic constraints caused by a shared genetic basis among traits. Here we created replicated, divergent selection lines for maternal egg investment in Japanese quail (Coturnix japonica) to quantify the role of genetic constraints in the evolution of egg size. We found that egg size responds rapidly to selection, accompanied by a strong response in all egg components. Initially, we observed a correlated response in body size, but this response declined over time, showing that egg size and body size can evolve independently. Furthermore, no correlated response in fecundity (measured as the proportion of days on which a female laid an egg) was observed. However, the response to selection was asymmetrical, with egg size plateauing after one generation of selection in the high but not the low investment lines. We attribute this pattern to the presence of genetic asymmetries, caused by directional dominance or unequal allele frequencies. Such asymmetries may contribute to the evolutionary stasis in egg size observed in natural populations, despite a positive association between egg size and fitness.

Por isso os emigrantes, certos de que voltem ao Brasil, não consideram uma eventual perda de identidade de seus filhos como um problema. Mas já existem dois grupos no Japão que começam a alarmar-se com o avanço da socialização japonesa dos seus filhos: mulheres nipo-brasileiras casadas com japoneses e famílias brasileiras com filhos em idade escolar. Trata-se então de apresentar neste trabalho duas estratégias conscientes para a preservação da identidade brasileira, focalisadas na manutenção do domínio da língua portuguesa. Refiro-me às atividades da associação "Grupo Brasil" em Tóquio, fundada por brasileiras casadas com japoneses, e as atividades da associação nipo-brasileira de Oizume.Brazilian emigration to Japan is a recent phenomenon. Therefore identity problems of the second generation, socialized in the country of emigration, don't seem yet very urgent. The first generation still believes that they will return to Brazil, and thus the possibility of an identity loss of their children seems far fetched. Nevertheless, there are already two different groups of Brazilian emigrants in Japan that begin to worry about the japanese socialization of their children: Brazilian women married to Japanese and Brazilian families with children in school age. This article analyses two different strategies of Brazilian associations trying to preserve the Brazilian identity by holding on to the Portuguese language: `Grupo Brasil' in Tokyo and the association of Brazilians in the town of Oizume.

Full Text Available El continuo auge económico y geopolítico de China nos recuerda que lo que actualmente se denomina China fue hace un tiempo el Reino del Centro, el centro del mundo. La implicación de esta afirmación es que al igual que la China histórica fue centro gravitacional global en Asia, su trayectoria actual puede reposicionar a China inexorablemente en el centro del orden mundial. El análisis histórico de Zhongguo o Zhonghua , la “Tierra del Medio” o la “Civilización Central”, y su postulación a convertirse en referencia moral universal, sin contar con la hegemonía geopolítica real sobre la región circundante, puede arrojar luz sobre este tema. La ambición de China se asemejaba a epítetos como “la Tierra de los hombres libres”, “la Nueva Roma” o “Zión”. Históricamente, la fuerza gravitacional que constituyó lo que algunos han denominado la sinoesfera procedía de esta postulación moral universal a la cual aspiraba. Dentro de la sinoesfera , en una compleja historia de negociación de relaciones con las sucesivas dinastías imperiales que gobernaban en el continente, Japón ha sido durante tiempo el punto focal de discusión sobre el significado y objetivo de la postulación china de representar el Reino del Centro. Efectivamente, a lo largo de su historia, Japón se ha definido a sí mismo a través del reconocimiento, la negación, la emulación o la demanda de esa centralidad. Quizás podamos entender mejor lo que China ha significado profundizando en las aspiraciones japonesas de ser China.

Is sexual motivational state linked to dopamine release in the medial preoptic area?

Science.gov (United States)

Kleitz-Nelson, H K; Dominguez, J M; Cornil, C A; Ball, G F

2010-04-01

The medial preoptic area (mPOA) is a key site for the dopaminergic enhancement of male sexual behavior. Dopamine release increases in the rat mPOA with mating, supporting the critical stimulatory role played by preoptic dopamine on male sexual behavior. However, it has been questioned whether dopamine is specifically related to the occurrence of male sexual behavior and not simply involved in general arousal. To address this question, we asked whether dopamine release in the mPOA is linked to the production of male sexual behavior in Japanese quail (Coturnix japonica), a species that exhibits a much shorter temporal pattern of copulation than rats and does not have an intermittent organ, resulting in a very different topography of their sexual response. Extracellular samples from the mPOA of adult sexually experienced male quail were collected every 6 min before, during, and after exposure to a female using in vivo microdialysis and analyzed using high-performance liquid chromatography with electrochemical detection. Extracellular dopamine significantly increased in the presence of a female and returned to baseline after removal of the female. However, quail that failed to copulate did not display this increased release. These findings indicate that it is not solely the presence of a female that drives dopamine release in males, but how a male responds to her. Furthermore, in quail that copulated, dopamine release did not change in samples collected during periods of no copulation. Together, these findings support the hypothesis that dopamine action in the mPOA is specifically linked to sexual motivation and not only to copulatory behavior or physical arousal.

Modified saponification and HPLC methods for analyzing carotenoids from the retina of quail: implications for its use as a nonprimate model species.

To investigate carotenoid content in the retina of Japanese quail (Coturnix japonica), for comparison with carotenoids in human retina, and to assess the effects of different saponification procedures on the recovery of quail retinal carotenoids. Extracted retinal carotenoids were saponified with methods adapted from recent studies, then identified and quantified with reverse-phase high-performance liquid chromatography (HPLC). To assess the effects of saponification conditions on carotenoid recovery from quail retina, we varied base concentration and the total time of saponification across a wide range and again used HPLC to compare carotenoid concentrations among conditions. Astaxanthin and galloxanthin were the dominant carotenoids recovered in the quail retina, along with smaller amounts of five other carotenoids (lutein, zeaxanthin, 3'-epilutein, epsilon-carotene, and an unidentified carotenoid). Astaxanthin was sensitive to saponification conditions; recovery was poor with strong bases (0.2 and 0.5 M KOH) and best with weak bases (0.01 and 0.2 M KOH). In contrast, xanthophyll carotenoids (galloxanthin, zeaxanthin, lutein, 3'-epilutein, and the unknown) were best recovered with strong base after 6 hours of saponification at room temperature. The recovery of epsilon-carotene was not affected by saponification conditions. Separate chemical hydrolysis procedures--using a strong base to recover xanthophylls and a weak base to recover astaxanthin--should be used for maximizing recovery of quail retinal carotenoids. Because the dominant carotenoids in quail retina are absent in human retina, and because of their different packaging (e.g., esterified in oil droplets) and light-absorbance properties compared with xanthophylls in the human eye, use of the quail as a model organism for studying human retinal carotenoids should be approached with caution.

State dependent learning effects have been widely studied in a variety of drugs of abuse. However, they have yet to be studied in relation to sexual motivation. The current study investigated state-dependent learning effects of cocaine in male Japanese quail (Coturnix japonica) using a sexual conditioning paradigm. Cocaine-induced state-dependent learning effects were investigated using a 2×2 factorial design with training state as one factor and test state as the other factor. During a 14-day training phase, male quail were injected once daily with 10mg/kg cocaine or saline and then placed in a test chamber after 15min. In the test chamber, sexual conditioning trials consisted of presentation of a light conditioned stimulus (CS) followed by sexual reinforcement. During the state dependent test, half of the birds received a shift in drug state from training to testing (Coc→Sal or Sal→Coc) while the other half remained in the same drug state (Coc→Coc or Sal→Sal). Results showed that male quail that were trained and tested in the same state (Coc→Coc or Sal→Sal) showed greater sexual conditioning than male quail that were trained and tested in different states (Sal→Coc) except when cocaine was administered chronically prior to the test (Coc→Sal). For the latter condition, sexual conditioning persisted from cocaine training to the saline test. The findings suggest that state dependent effects may alter sexual motivation and that repeated exposure to cocaine during sexual activity may increase sexual motivation which, in turn, may lead to high risk sexual activities. An alternative explanation for the findings is also discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

SUMMARY: Polychlorinated biphenyls constitute a group of chlorine-bearing compounds of industrial origin that have permeated the natural environment throughout the world. Their chemical structure resembles that of some of the organochlorine pesticides. They are troublesome interferences in gas chromatographic analysis of these pesticides. Although methods have been developed to overcome analytical problems, measurements of quantity still are only approximate. Special studies in the United States, Netherlands, and Great Britain have traced PCB's to industrial effluent, but other possible sources have not been followed. Their use in paints, cartons, and insulating fluids suggests that environmental pollution may be from many different sources. PCB's are present in fish and wildlife in many countries of the world. Quantities are higher in animals living near industrial areas. PCB's build up in biological food chains with increases of tens to thousands of times from lower to higher organisms. Experimental studies have shown that PCB's have a toxicity to mallards, pheasants, bobwhite quail, coturnix quail, red-winged blackbirds, starlings, cowbirds, and grackles that is of the same order as the toxicity of DDE to these species. Overt signs of poisoning also are similar to those caused by compounds of the DDT group. Toxic effects of DDE and Aroclor 1254 to coturnix chicks were additive, but not synergistic. PCB's containing higher percentages of chlorine are more toxic to birds than those containing lower percentages. PCB's of foreign manufacture contained contaminants to an extent that greatly increased their toxicity Aroclor 1242. Statistical evaluations of the role that different chemicals may play in thinning of eggshells of brown pelicans show that DDE residues correlate better with shell thinning than do residues of dieldrin or PCB's. Studies of the effects of PCB's in the environment are as yet insufficient for well-rounded conclusions. The evidence available

Full Text Available Le secteur appelé San Gabán/lnambari (district de San Gabán, province de Carabaya, Puno situé sur les derniers contreforts de la Cordillère Nevada de Carabaya, est peuplé par des immigrants des hauts plateaux - plus particulièrement des provinces de Melgar et de Carabaya mais aussi de quelques districts de la province d'Azangaro - qui y sont confrontés, en l'absence d'une voie de communication, avec des conditions particulières d'isolement géographique, culturel, économique et politique. Cette transplantation dans la forêt vierge - mouvement migratoire spontané - pose aux immigrants, qu'ils soient permanents ou temporaires, de nombreux problèmes d'adaptation, problèmes d'autant plus importants que les colons abordent les terres basses sans aucune préparation psychologique, éducative et technique. On examine ici le comportement et les réactions des individus dans le domaine de l'alimentation. La première partie de l'étude est consacrée aux composants de l'alimentation. Cette dernière repose avant tout sur les végétaux cultivés et plus particulièrement sur le riz, le manioc, le maïs, les « papas japonesas » et les bananes. Elle est irrégulièrement complétée par les produits de la basse-cour, par un peu de gibier et de poisson et par des denrées que les immigrants font venir ou rapportent de leur village d'origine à l'occasion de leurs voyages périodiques. Parmi ces denrées figurent surtout le chuño, la farine de chuño, la farine d'orge, la cañihua, le charqui, les pâtes, l'huile, le sucre et le sel. On ne peut manquer d'être frappé par le parallélisme existant entre les aliments adoptés et ceux dont l'immigrant se nourrissait dans son district d'origine. On remarque que la satisfaction des besoins alimentaires pose à l'individu un sérieux problème d'adaptation aux ressources locales. Cette adaptation est lente car l'immigrant adopte envers le milieu, semble-t-il, une attitude défensive. Sa m

Full Text Available This paper describes a historical study combined with a non-destructive chemical and molecular characterisation (using ESEM-EDS and Raman spectroscopy of nine small sculptures. The specimens kept in the National Museum of Natural Sciences (MNCN institution are composed of steatite or soapstone, a soft and unctuous mineral containing talc and pyrophyllite. We found that two of the specimens are made of pyrophyllite from Japan while the other seven are talc carved with Chinese-style ornamentation. These talc specimens from China include calcite formed by dolomite metamorphism, while the pyrophyllite samples show Pb, Fe, Cl, As, P, S, Na and Ca, chemical elements more characteristic of hydrothermal alterations of felsic rocks from Japan. The statuettes were brought to what was then the RGHN from Philippines in the eighteenth century by Juan de Cuellar. The paper includes a short biography of this Spanish explorer and botanist and an account of his scientific and economic activities. These specimens are an excellent example of the Enlightenment fashion for collecting Asian objects.Se presenta un estudio histórico y de caracterización química y molecular por técnicas no destructivas, ESEMEDS y Raman, de nueve esculturas de pequeño tamaño, fabricadas en esteatita, antigua denominación de minerales blandos y untuosos como talco y pirofilita, conservadas en el Museo Nacional de Ciencias Naturales (MNCN. Se concluye que dos especímenes son de pirofilita y procedentes de Japón, mientras que las otras siete son de talco con ornamentación de procedencia China. Las muestras de talco de China tienen calcita con algo de cobre, típica de metamorfismo de dolomías, mientras que las pirofilitas tienen Pb, Fe, Cl, As, P, S, Na y Ca, elementos químicos de origen hidrotermal de rocas félsicas más característico de Japón. Las estatuillas fueron aportadas al RGHN desde Filipinas, en el siglo XVIII, por D. Juan de Cuellar, expedicionario y botánico español, de quien se incluye un recorrido por su biografía y actividades científico-económicas.

Wild-trapped starlings (Sturnus vulgaris) were fed concentrations of Morsodren (2, 4, and 8 ppm), DDE or Aroclor 1254 (5, 25, and 100 ppm), or malathion (8, 35, and 160 ppm) that were found to be sublethal in pen-reared Coturnix quail fed these amounts for 12 weeks. Plasma enzymes had to be measured earlier than planned in starlings fed Morsodren (at three weeks) or the organochlorine compounds (at seven weeks) because of unexpected, subsequent mortality. Variations in enzyme response were greater in wild than in pen-reared birds, but not enough to mask the toxicant-induced changes in enzyme activity. Cholinesterase activities decreased in birds fed Morsodren or malathion, and increased in those fed the organochlorine compounds. Lactate dehydrogenase activities increased two-fold in starlings fed Morsodren and two- to four-fold in those fed the organochlorine compounds, but only 50% in those fed malathion. Further examination of enzyme profiles showed that creatine kinase and aspartate aminotransferase activities increased two-to four-fold in birds fed Morsodren or the organochlorine compounds but not at all in those fed malathion. Thus the classes of environmental contaminants fed to starlings could be easily distinguished by these enzymatic parameters. Evaluation of enzymatic profiles appears to be a potentially valuable technique to monitor the presence of toxicants in wild populations, especially if used to complement standard chemical residue analyses. Here the residue analyses showed, after three weeks feeding, that mercury in the carcasses reflected the concentrations fed daily, whereas accumulation in the livers was two- to four-fold greater. After seven weeks feeding, liver residues of either organochlorine compound were about three-fold higher than the concentrations fed daily. However, four times as much DDE as Aroclor 1254 had accumulated in the carcasses.

Full Text Available Abstract Background Two atherosclerosis-susceptible and -resistant Japanese quail (Coturnix japonica strains obtained by divergent selection are commonly used as models to study atherosclerosis, but no genetic characterization of their phenotypic differences has been reported so far. Our objective was to examine possible differences in the expression of genes involved in cholesterol metabolism and transport in the liver between these two strains and to evaluate the value of this model to analyze the gene system affecting cholesterol metabolism and transport. Methods A factorial study with both strains (atherosclerosis-susceptible versus atherosclerosis-resistant and two diets (control versus cholesterol was carried out. The mRNA concentrations of four genes involved in cholesterol biosynthesis (HMGCR, FDFT1, SQLE and DHCR7 and three genes in cholesterol transport (ABCG5, ABCG8 and APOA1 were assayed using real-time quantitative PCR. Plasma lipids were also assayed. Results Expression of ABCG5 (control diet and ABCG8 (regardless of dietary treatment and expression of HMGCR, FDFT1 and SQLE (regardless of dietary treatment were significantly higher in the atherosclerosis-resistant than in the atherosclerosis-susceptible strain. Plasma triglyceride and LDL levels, and LDL/HDL ratio were significantly higher in the atherosclerosis-susceptible than in the atherosclerosis-resistant strain fed the cholesterol diet. In the atherosclerosis-susceptible strain, ABCG5 expression regressed significantly and positively on plasma LDL level, whereas DHCR7 and SQLE expression regressed significantly and negatively on plasma triglyceride level. Conclusions Our results provide support for the hypothesis that the atherosclerosis-resistant strain metabolizes and excretes cholesterol faster than the atherosclerosis-susceptible strain. We have also demonstrated that these quail strains are a useful model to study cholesterol metabolism and transport in relation with

Hazards of soil-borne Pb to wild birds may be more accurately quantified if the bioavailability of that Pb is known. To better understand the bioavailability of Pb to birds, we measured blood Pb concentrations in Japanese quail (Coturnix japonica) fed diets containing Pb-contaminated soils. Relative bioavailabilities were expressed by comparison with blood Pb concentrations in quail fed a Pb acetate reference diet. Diets containing soil from five Pb-contaminated Superfund sites had relative bioavailabilities from 33%-63%, with a mean of about 50%. Treatment of two of the soils with phosphorus significantly reduced the bioavailability of Pb. Bioaccessibility of Pb in the test soils was then measured in six in vitro tests and regressed on bioavailability. They were: the “Relative Bioavailability Leaching Procedure” (RBALP) at pH 1.5, the same test conducted at pH 2.5, the “Ohio State University In vitro Gastrointestinal” method (OSU IVG), the “Urban Soil Bioaccessible Lead Test”, the modified “Physiologically Based Extraction Test” and the “Waterfowl Physiologically Based Extraction Test.” All regressions had positive slopes. Based on criteria of slope and coefficient of determination, the RBALP pH 2.5 and OSU IVG tests performed very well. Speciation by X-ray absorption spectroscopy demonstrated that, on average, most of the Pb in the sampled soils was sorbed to minerals (30%), bound to organic matter (24%), or present as Pb sulfate (18%). Additional Pb was associated with P (chloropyromorphite, hydroxypyromorphite and tertiary Pb phosphate), and with Pb carbonates, leadhillite (a lead sulfate carbonate hydroxide), and Pb sulfide. The formation of chloropyromorphite reduced the bioavailability of Pb and the amendment of Pb-contaminated soils with P may be a thermodynamically favored means to sequester Pb.

Full Text Available Background: Aspergillus flavus is the most important fungus for production of Aflatoxin B1 (AFB1. This study evaluated the ability of gamma rays (GRs and electron-beam irradiation (EBI to counteract the deleterious effects of aflatoxin B1 (AFB1 in a chicken model. Methods: Overall, 168 one-day-old male Coturnix quails were assigned to eight treatments for 42 d in Tehran, Iran, in 2010 and 2011. Two dietary inclusion rates of AFB1 (0 and 2 ppm and toxin binders, such as 0, 27 kGy doses of GRs, 27 kGy doses of EBI, and 0.3% of commercial toxin binder-milbond-TX, were tested in a 2×4 factorial manner. Serum biochemical parameters, immune response, and dietary treatments on factors associated with kidney and lipid profiles were determined on day 42. Results: AFB1 significantly decreased the hematological parameters (Hematocrit in 21 and 42 d, immune response (White blood cell (WBC, heterophil to lymphocyte ratio (H/L and sheep red blood cell (SRBC, and blood chemical factors (glucose, albumin, total protein, and triglycerides compared to the control diet (P<0.05. It also significantly increased the calcium, phosphorus, uric acid, and low-density lipoprotein (LDL levels (P<0.05. The addition of toxin binders, such as GRs, EBI, and milbond-TX, in the contaminated diets significantly diminished the inhibitory effects of dietary AFB1 (P<0.05 on the hematological parameters, immune response, blood chemical factors, and factors associated with kidney and lipids profile with no differences compared to the control diet. Conclusion: The addition of these toxin binders may reduce the adverse effects produced by the presence of AFB1 in Japanese quails’ diets.

Birds have extremely varied reproductive strategies. As such, the impact of endocrine disrupting chemicals (EDCs) can greatly differ across avian species. Precocial species, such as Japanese quail appear to be most sensitive to EDC effects during embryonic development, particularly sexual differentiation. A great deal is known about the ontogeny of Japanese quail (Coturnix japonica) relative to endocrine, neuro-endocrine, and behavioral components of reproduction. Therefore, this species provides an excellent model for understanding effects of EDCs on reproductive biology with exposure at specific stages of the life cycle. The purpose of these experiments was to conduct a 1- or 2- generation experiment with positive or negative control chemicals and to determine changes in selected end points. Japanese quail embryos were exposed to estradiol benzoate (EB; positive control) in a 2-generation design or to fadrozole (FAD; negative control) in a 1-generation design. Embryonic EB treatment resulted in significant reductions (p< 0.5) in hen day production (90.2 vs 54.1; control vs EB, resp.) and fertility (85.3 vs 33.4%, control vs EB, resp.). Males showed sharply reduced courtship and mating behaviors as well as increased lag time (26 vs 148 sec; control vs EB) in behavioral tests. Fadrozole exposure resulted in reduced hatchability of fertile eggs, particularly at higher doses. There were no significant effects on courtship and mating behavior of males although males showed an increased lag time in their responses, nally, a behavioral test for studying motor and fear responses in young chicks was used; chicks exposed to an estrogenic pesticide (methoxychlor) showed some deficits. In summary, the use of appropriate and reliable end points that are responsive to endocrine disruption are critical for assessment of EDCs. Supported in part by EPA grant R826134.

Se ha pensado que tanto los factores ambientales como genéticos pueden predisponer a la Enfermedad de Parkinson (EP. Esta enfermedad es causada por una deficiencia de dopamina en el sistema nigrostriatal, la cual resulta de una degeneración selectiva de las neuronas dopaminérgicas en la zona compacta de la substancia nigra en el cerebro medio y afecta a más del 1% de la población general mayor de 55 años de edad, manifestándose principalmente por rigidez, bradiquinesia y temblor. Las formas familiares de la enfermedad aportan evidencia de factores genéticos de susceptibilidad en las cuales se observa segregación mendeliana con patrón de herencia autosómica tanto dominante como recesiva.

2014-07-01

Full Text Available O presente trabalho apresenta um mapeamento tecnológico dos processos de produção do ácido succínico a partir de fontes renováveis. O ácido bio-succínico foi escolhido por ter ampla aplicação na indústria de transformação, além de sua produção estar relacionada com a valorização de resíduos lignocelulósicos, enfatizando um novo direcionamento para o desenvolvimento industrial de forma sustentável, com base no conceito de biorrefinaria. A análise dos documentos de patentes BR identificou, dentre outros aspectos, ausência de pedidos de residentes brasileiros, no cenário nacional, e o significante número de depósitos de patentes BR com prioridade, principalmente, japonesa e americana. Fatores como o pouco conhecimento dos residentes brasileiros sobre proteção da propriedade intelectual e o complexo processo de integração universidade-empresa podem justificar esse panorama. Além disso, o fato do Brasil apresentar alta disponibilidade de recursos naturais, ser pouco competitivo no campo da biotecnologia e conhecido importador de produtos com alto valor agregado também pode explicar o interesse americano e japonês nesses setores específicos. Dentre os processos de produção de ácido succínico investigados, os procedimentos que fizeram uso de técnicas de Engenharia Genética estavam em maioria, indicando que esses processos podem ser mais competitivos frente as demais estratégias analisadas. Sendo assim, esse trabalho representa uma breve análise na área de prospecção de um bloco de construção para síntese química – o ácido succínico – que é/será essencial à economia brasileira e da qual o Brasil ainda é dependente de desenvolvimentos estrangeiros.

Full Text Available Este ensaio delineia a emergência da Amazônia no imaginário norte-americano no período da Segunda Guerra Mundial. Embora a importância geopolítica de diversificação dos mercados fornecedores de borracha e o desenvolvimento da borracha sintética tenham sido discutidos nos Estados Unidos antes do ataque a Pearl Harbor, a subsequente interdição japonesa aos mercados tradicionais do sudeste asiático levou burocratas e cientistas a se apressarem na busca de alternativas. Como em outras regiões da América Latina, as políticas de obtenção e fornecimento, durante a guerra, dividiram os progressistas adeptos do New Deal e os conservadores fiscais. Entretanto, a política de gestão norte-americana também moldou e foi moldada por mitos enraizados acerca das regiões e populações tropicais. Na época, como agora, a Amazônia era muito mais que um lugar: para os norte-americanos, era também uma pedra de toque das ansiedades mais profundas concernentes às questões de raça, classe e nação.This essay traces the emergence of the Amazon in the United States wartime imaginary. Although the geopolitical importance of diversifying rubber markets and developing synthetics had been discussed in the United States before Pearl Harbor, the subsequent Japanese interdiction of traditional Southeast Asian markets sent American government officials and scientists scurrying to find alternatives. As in other regions of Latin America, wartime procurement policies in the Amazon divided New Deal progressives and fiscal conservatives, but these policies also shaped and were shaped by entrenched myths of tropical regions and populations. Then, as now, the Amazon was more than a place, but also a flashpoint for Americans for deeper anxieties concerning questions of race, class, and nation.

En realidad, de forma distinta a línea dura hacia los Estados Unidos, la política China hacia Japón durante la guerra fría fue en gran parte flexible y suave, que se muestra normalmente en su Diplomacia Popular basado en contactos no-gubernamentales. Este trabajo no sólo analiza los orígenes y desarrollo de este nuevo enfoque diplomático, pero también explora su impacto en Japón y en la alianza de seguridad Estados Unidos-Japón. Según fuentes chinas, americanas, japonesas y de los documentos disponibles recientemente, se argumenta que la Diplomacia Popular, de tono suave y una gran flexibilidad, de hecho, minaba la alianza de Estados Unidos y Japón durante la guerra fría.__________ABSTRACT:For years, in regard to the East Asia cold war and the Chinese foreign policy, scholars have focused more on the Sino-American confrontation or tough Sino-Soviet relations but ignored China's policy toward Japan. Actually, different from its tough policy toward the United States, the Chinese Japan policy during the cold war was largely flexible and soft, which was typically shown in its People's Diplomacy with emphasis on non-governmental contacts. This paper not only discusses the origins and development of this new diplomatic approach but also explores its impacts on Japan and the US-Japan security alliance. Based on Chinese, American, and Japanese sources recently available, it argues that the People's Diplomacy, with its soft tone and great flexibility, effectively undermined the US-Japan cold war security alliance.

Full Text Available OBJETIVO. Analizar factores de salud, laborales y sociales que contribuyen a renunciar al trabajo en dos maquiladoras transnacionales del ramo electrónico de Tijuana. MATERIAL Y MÉTODOS. Se realizó un estudio de cohorte a 725 mujeres empleadas en una planta japonesa y una estadunidense, entre enero de 1992 y marzo de 1994. La muestra se estratificó en dos intervalos de tiempo ­30 y >30 días laborados. Se efectuó un seguimiento de las mujeres hasta su renuncia o final del periodo de observación, mediante la recolección de información sobre variables de salud, sociales y ocupacionales de diversas fuentes de registro obtenidas de su centro de trabajo. Los motivos de renuncia y la confiabilidad de los datos obtenidos de los registros se estudiaron por medio de entrevistas de seguimiento realizadas a 46% (n= 148 de las trabajadoras que renunciaron y fueron localizadas aproximadamente 12 meses (desviación estándar= 6.7 después de su renuncia. RESULTADOS. La probabilidad acumulativa de renunciar al trabajo fue de 67% en el primer año y de 81% en el segundo. La ausencia de antecedentes laborales previos, turno diurno y nacionalidad de la compañía, resultaron factores predictivos para la renuncia al empleo durante los primeros 30 días. Tabaquismo, antecedentes quirúrgicos y haberse incapacitado por enfermedad general, después de controlar por otras variables, actuaron como factores predictivos para la renuncia posterior a 30 días. En contraposición, la tasa de renuncia posterior a 30 días resultó menor para mujeres con enfermedades crónicas. CONCLUSIONES. La renuncia al empleo en las maquiladoras es elevada y selectiva; en tanto que los factores ocupacionales se asociaron con la renuncia temprana, los relacionados con la salud fueron mejores factores predictivos para la renuncia posterior a los primeros 30 días.

Full Text Available Desde sus primeras manifestaciones hace más de un siglo, el cómic se ha ido consolidando como un género popular sobretodo dirigido a un lector juvenil. Su evidente atractivo entre los lectores ha hecho que algunos padres, educadores y profesionales del ámbito de la promoción de la lectura se plantearan el por qué de dicha afición, llegando a conclusiones erróneas como la creencia de que se trata de una lectura menor, dirigida esencialmente a la pura distracción de quien los lee. El manga, en concreto, es el género dentro del cómic que más se consume en occidente. Se ha convertido en un fructífero producto de mercado que deriva en videojuegos, series de televisión, películas de cine… Su gran acogida entre el público infantil y juvenil preocupa a mediadores por la supuesta carga violenta y sexual y la baja calidad literaria de sus obras.

In the present study, we investigated the oxidative biotransformation of 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) and 2,2',4,4',5-pentabromodiphenyl ether (BDE-99) by liver microsomes from wild lesser snow geese (Chen caerulescens caerulescens) and domesticated Japanese quail (Coturnix japonica). Formation of hydroxy-metabolites was analyzed using an ultra-high performance liquid chromatography-tandem mass spectrometry-based method. Incubation of BDE-47 with avian liver microsomes produced sixteen hydroxy-metabolites, eight of which were identified using authentic standards. The major metabolites formed by liver microsomes from individual lesser snow geese were 4-hydroxy-2,2',3,4'-tetrabromodiphenyl ether (4-OH-BDE-42), 3-hydroxy-2,2',4,4'-tetrabromodiphenyl ether (3-OH-BDE-47), and 4'-hydroxy-2,2',4,5'-tetrabromodiphenyl ether (4'-OH-BDE-49). By comparison, 4-OH-BDE-42 and 4'-OH-BDE-49, but not 3-OH-BDE-47, were major metabolites of Japanese quail liver microsomes. Unidentified metabolites included monohydroxy- and dihydroxy-tetrabromodiphenyl ethers. Incubation of BDE-99 with avian liver microsomes produced seventeen hydroxy-metabolites, twelve of which were identified using authentic standards. The major metabolites formed by lesser snow goose liver microsomes were 2,4,5-tribromophenol, 3-OH-BDE-47, 4'-OH-BDE-49, 4-hydroxy-2,2',3,4',5-pentabromodiphenyl ether (4-OH-BDE-90), and 5'-hydroxy-2,2',4,4',5-pentabromodiphenyl ether (5'-OH-BDE-99). By comparison, the major metabolites produced by liver microsomes from Japanese quail included 6-hydroxy-2,2',4,4'-tetrabromodiphenyl ether (6-OH-BDE-47) and 2-hydroxy-2',3,4,4',5-pentabromodiphenyl ether (2-OH-BDE-123), but not 3-OH-BDE-47. Unidentified metabolites consisted of monohydroxy-pentabromodiphenyl ethers, monohydroxy-tetrabromodiphenyl ethers and dihydroxy-tetrabromodiphenyl ethers. Another difference between the two species was that formation rates of BDE-47 and BDE-99 metabolites were greater with liver

Full Text Available RESUMEN En 2007, Tezuka Architects construyen en las cercanías de Tokio la Guardería Fuji, e inmediatamente ésta se convierte en uno de los edificios educativos más valorados, cosechando numerosos premios y reconocimientos nacionales e internacionales. El diseño de este edificio se enmarca en una línea de trabajo muy personal de esta pareja de arquitectos, que enlaza además con ciertos valores de la arquitectura japonesa tradicional, como la relación con el vacío y con la naturaleza, en la que desarrollan sus proyectos buscando convertirlos en fondos sobre los que se desarrolle la actividad de sus usuarios, siendo así capaces de dotar de calidad a las relaciones de los mismos, tanto entre sí, como con el propio edificio y el entorno que los rodea. Para conseguir esto establecen una serie de mecanismos proyectuales que persiguen alcanzar la esencia de la arquitectura y el entendimiento de aquellas necesidades propias de los usuarios cuya reinterpretación les permite alcanzar soluciones basadas en un entendimiento primigenio, más allá de soluciones funcionales preestablecidas. SUMMARY In 2007, Tezuka Architects build Fuji Kindergarten, on the outskirts of Tokyo. Immediately it becomes one of the most valued educational buildings, earning a lot of national and international awards and recognitions. The design of this building is part of a very personal way of working of this couple of architects, which also links with certain values of traditional Japanese architecture, such as the relationship with both emptiness and nature. Regarding this relationship, they develop their projects looking for turning them into backgrounds, on which the users´ activity is developed, in such a way that they are able to provide quality to their relationships, among themselves, with the building itself and with the environment surrounding them. To achieve this, they establish a series of projectual mechanisms, which seek to get both the essence of

Esta distinção se confirma e acentua quando se compara a natureza dos componentes do óleo essencial da menta "Campinas" M. A. 701, descrita no presente trabalho, com a menta japonêsa comum. A maior produtividade da nova variedade comparada com a da menta japonesa comum foi desde logo também constatada pelos primeiros lavradores, a quem foram enviadas pequenas quantidades de rizomas, para plantio experimental. Foram cultivados em 1949-50 cêrca de 12 hectares; cm 1950-51, cêrca de 900 ha, e o prognóstico é que essa variedade tende a substituir totalmente a menta japonêsa anteriormente cultivada em São Paulo, devido ao seu maior valor econômico.A seedling, designated M.A.701, remarkable for its vigor and resistance to rust, was discovered during the fourth year of selection of Japanese mint (Mentha arvensis L. subsp. haplocalix Briquet var. piperascens Holmes or forma piperascens Malinvaud. The botanical characters of the variety derived from this seedling, especially the vegetative habit and colouring of leaves and stems, make it quite different from the original variety. This difference is enhanced, when we compare the nature of the essential oil components of "Campinas" M.A.701, as described in the present paper, with that of the common Japanese mint. The higher yield of the new variety, compared with that of the common Japanese mint, was soon confirmed by the first cultivators, to whom small quantities of rhizomes were sent for experimental planting. About 12 hectars were cultivated em 1949/50 and about 900 hectars in 1950/51. It is expected that the new variety will, on account

¿Es el sistema calicreína/quinina renal un factor modulador de la calciuria?

Full Text Available La reabsorción tubular de calcio es uno de los principales factores que determinan la concentración sérica de calcio y su excreción urinaria. El túbulo contorneado distal y conector es donde se produce la regulación fina de la calciuria. A ese nivel se encuentra el canal epitelial de Ca (TRPV5, que es el paso limitante en el transporte transcelular de Ca. La presencia dinámica del canal TRPV5 en la superficie de la célula tubular está mediada por un proceso de reciclado endosómico. Distintos factores intrarrenales intervienen en la fijación del canal de calcio en la membrana aplical, entre ellos la hormona antienvejecimiento klotho y la calicreína tisular (CT. Ambas proteínas son sintetizadas en el túbulo distal y secretadas en el fluido tubular. La calicreína tisular estimula la reabsorción activa de calcio por vía del receptor de bradiquinina tipo 2 que compromete la activación del of TRPV5 por vía de la protein cinasa C. Los ratones deficientes en CT muestran hipercalciuria de origen renal comparable a la pérdida de calcio que se observa en los ratones knockout para el TRPV5. Existe un polimorfismo con pérdida de función del gen de la CT humana denominado R53H (alelo H que produce una gran disminución de la actividad enzimática. La presencia del alelo H, por lo menos en la población japonesa, parece ser frecuente (24%. Estos individuos tiene una tendencia a excreción más alta de calcio y sodio en orina que se manifiesta más durante la infusión de furosemida. En el futuro habrá que estudiar si la manipulación del sistema calicreína-quinina renal permite corregir la hipercalciuria idiopática con fármacos diferentes a los diuréticos tiazídicos.

Foram utilizadas 320 codornas, resultado do cruzamento entre a codorna japonesa e a européia de 60 a 144 dias de idade, com peso vivo médio de 178+12 g, alimentadas com rações contendo 20 e 23% de proteína bruta (PB e, 0,80; 0,95; 1,10; 1,25 e 1,40% de lisina. O delineamento experimental foi o inteiramente ao acaso em esquema fatorial 2x5 (dois níveis de PB x cinco níveis de lisina, que resultou em dez tratamentos, cada um com quatro repetições de oito aves. As codornas foram submetidas a um programa de luz de 17 horas de duração e alimentadas à vontade. As variáveis estudadas foram obtidas em quatro períodos de 21 dias. Houve efeito quadrático dos níveis de lisina sobre a produção de ovos, sendo a exigência e o consumo, respectivamente, de 1,07% e 287 mg de lisina/dia com 20%PB e de 1,15% e 321 mg de lisina/dia com 23%PB. O nível de 23%PB aumentou o consumo de ração, produção, peso e massa de ovos e também melhorou a conversão alimentar por massa e dúzia de ovos. As relações lisina: PB não foram alteradas, sendo de 5,3 e 5,0%, respectivamente, com 20 e 23% de PB na ração. Os resultados do presente estudo sugerem aumento quantitativo da exigência de lisina de codornas na fase de produção, mas não da relação lisina: PB, à medida que a concentração de PB na ração é elevada.

ROCV was first isolated in 1975 from the cerebellum of a fatal human case of encephalitis. Clinical manifestations of the illness are similar to those described for St. Louis encephalitis. ROCV shows intense antigenic cross-reactivity with Japanese encephalitis complex (JEC viruses, particularly with Ilheus (ILHV, St. Louis encephalitis, Murray Valley and West Nile viruses. In this study, we report a specific RT-PCR assay for ROCV diagnosis and the molecular characterization of the SPAn37630 and SPH37623 strains. Partial nucleotide sequences of NS5 and E genes determined from both strains were used in phylogenetic analysis. The results indicated that these strains are closely related to JEC viruses, but forming a distinct subclade together with ILHV, in accordance with results recently reported by Medeiros et al.

Nucleoli are the product of the activity of nucleolar organizer regions (NOR) in certain chromosomes. Their main functions are the formation of ribosomal subunits from ribosomal protein molecules and the transcription of genes encoding rRNA. The aim of the study was to determine the shape of nucleoli and analyse methylation in the gene RN28S in the spermatocytes of male Japanese quail (Coturnixjaponica) in two age groups. Nucleoli were analysed in cells of the first meiotic prophase. Their number and shape were determined and they were classified as regular, irregular or defragmented. In the cells of the young birds no defragmented nucleoli were observed, with regular and irregular nucleoli accounting for 97% and 3%, respectively. In the cells of older birds no regular nucleoli were observed, while irregular and defragmented nucleoli accounted for 37% and 67%, respectively. MSP (methylation-specific PCR) showed that the gene RN28S is methylated in both 15-week-old and 52-week-old quails. In recent years an association has been established between nucleolus morphology and cellular ageing processes.

Full Text Available The objective of this study was to assess the effect of the inclusion of passionflower (Passiflora alata in diets on performance, behavior, heterophil/lymphocyte ratio (H/L, corticosterone plasma levels (CPL and immune response of quails. The study was carried out using 192 birds, distributed in randomized blocks with 4 diets (0, 125, 250 and 375 and 0, 250, 500 and 750 mg of passionflower/kg of feed for the rearing and laying period, respectively, 8 replicates and 6 birds per experimental unit. The rearing period began when birds were 28 days of age and it lasted for 15 days. In this phase, it was evaluated daily feed intake, daily weight gain, feed conversion, viability, tonic immobility time, intensity of injuries, behavior, heterophil/lymphocyte ratio, and corticosterone plasma levels. Laying phase started when birds were 43 days of age and it finished when they were 140 days of age; it was compesed of six 14-day cycles in which it evaluated feed intake, feed conversion, egg production and quality, viability, tonic immobility time, intensity of injuries, behavior, heterophil/lymphocyte ratio, corticosterone plasma levels and immune response. In the rearing period, the use of passionflower in the diet of quails influenced the behavioral parameters, and the birds became calmer, mainly at the dosage of 375 mg/kg of ration. However, in the laying period, passionflower was efficient in reducing stress in the quails, and the most promising results are observed when higher dosages of the phytotherapic were applied. Nevertheless, the dose of 750 mg/kg of feeeding reduces egg production, though it does not influence quality of eggs neither immune response of the quails.Objetivou-se avaliar o efeito da inclusão de passiflora na ração sobre o desempenho, o comportamento, a relação heterófilo/linfócito, a concentração plasmática de corticosterona e a imunidade de codornas. Foram utilizadas 192 aves, distribuídas em blocos casualizados com 4 dietas (0, 125, 250 e 375, e 0, 250, 500 e 750 mg de passiflora/kg de ração nas fases de recria e postura, respectivamente, 8 repetições e 6 aves por parcela. A fase de recria iniciou-se aos 28 dias de idade das aves e teve duração de 15 dias. Nesta fase foram avaliados o consumo diário de ração, o ganho diário de peso, a conversão alimentar, a viabilidade, o tempo em imobilidade tônica, a intensidade de ferimentos, o comportamento, a relação heterófilo/linfócito e concentração plasmática de corticosterona. A fase de postura teve início quando as aves atingiram 43 dias de idade e seu término encerrou-se aos 140 dias de idade das aves; foi constituída de seis ciclos de 14 dias, nos quais foram avaliados o consumo de ração, a conversão alimentar, a produção e qualidade de ovos, a viabilidade, o tempo em imobilidade tônica, a intensidade de ferimentos, o comportamento, a relação herófilo/linfócito, a concentração plasmática de corticosterona e a resposta imunológica. Na fase de recria, o uso de passiflora na dieta de codornas influenciou os parâmetros comportamentais, tornando as aves mais calmas, principalmente na dosagem de 375 mg/kg de ração. Já na fase de postura, foi eficaz na redução do estresse das codornas, e os resultados mais promissores foram observados quando aplicadas as maiores dosagens do fitoterápico. A dosagem de 750 mg/kg de ração, no entanto, diminui a produção de ovos, embora não tenha influência na qualidade dos ovos nem a resposta imunológica das aves.

A religiosidade de Messiaen representa uma forma de nostalgia para a vanguarda intelectual francesa. Messiaen considera o senso de ritual e de estase como expressões musicais do sagrado. Através da comparação da estrutura do Gagaku de Messiaen (analisado à luz de seus próprios escritos sobre os seus métodos composicionais e da estrutura da música tradicional japonesa gagaku, este artigo mostra de que modo o senso de ritual e de estase constitui o elemento estético comum existente independentemente em ambas as formas musicais. A existência de um elemento comum entre a "fonte" não-ocidental e a composição ocidental inspirada por esta fonte provê a condição necessária para a transformação de nostalgia em inovação. O conceito de écriture tem um papel importante na dialética de passado/futuro desta transformação, causando estrutura e estilo a se diferenciarem baseados no princípio da não-imitação, e afirmando-se como o elemento formativo que faz de Gagaku uma peça distintamente francesa.The tension between nostalgia and innovation is uniquely manifested in Olivier Messiaen's Gagaku, the fourth movement of his 1962 composition Sept Haikai.

Full Text Available En este artículo se presentan los resultados de un estudio experimental a cerca de la influencia de la incorporación de fibras de acero en el comportamiento del hormigón frente a esfuerzos de corte, medidos utilizando el ensayo JSCE - SF6, modificado. Usando los resultados de los ensayos realizados se evalúa La capacidad de disipación de energía del hormigón durante la rotura o tenacidad del hormigón reforzado con fibras en función del contenido y tipo de Fibra utilizada. Con los resultados obtenidos, se puede concluir que la incorporación de fibras como refuerzo al esfuerzo de corte aumenta la ductilidad del hormigón, permitiendo mayores deformaciones que un hormigón convencional. Se observa que la capacidad de absorber energía de los hormigones, cuantificada a través de la tenacidad absoluta, se incrementa más de tres veces cuando se incorporar fibras y no se tienen roturas frágiles. Por lo tanto, la incorporación de fibras como refuerzo es una buena solución para mejorar la respuesta del hormigón ante solicitaciones de corte. Por otra parte, se demuestra que el ensayo de corte propuesto por la recomendación japonesa JSCE-SF6, levemente modificada, entrega resultados coherentes y reproducibles, permitiendo cuantificar diferentes propiedades del hormigón reforzado con fibras sometido a solicitaciones de corte.This paper presents the results of an experimental research on influence of steel fibers on shear behavior of concrete, using modified JSCE - SF6 test. The tests results are used to evaluate the energy dissipation capacity of concrete during failure or fiber reinforced concrete toughness, in terms of amount and type of fibers. With the results, it can be concluded that the addition of fibers as shear reinforcement influence significantly the ductility of concrete. The results show that the absorption energy capacity of concrete, measured by mean of absolute toughness, increase 3 times when concrete is reinforced with

From the LC50 values obtained for these insecticides, it was found that all mosquito species including the field strains of Cx. quinquefasciatus and Ae. albopictus were highly susceptible Except for Cx. quinquefasciatus (field strain against malathion, 100% mortality was observed at the discriminating dosages recommended by World Health Organization. The residual effect of alphamethrin, deltamethrin, malathion and folithion at 25 mg (ai/m² on different surfaces against six species of vector mosquitoes showed that alphamethrin was the most effective on all four treated surfaces (mud, plywood, cement and thatch. Nevertheless, residual efficacy lasted longer on thatch than on the other surfaces. Therefore, synthetic pyrethroids such as alphamethrin can be effectively employed in integrated vector control operations.Três compostos organo-fosforados - malation, folition e temefos -e dois piretroides sintéticos - alfametrina e deltametrina - foram usados para controlar o estado da susceptibilidade das larvas e adultos de seis mosquitos vetores na Índia.

Full Text Available O presente artigo analisa a aproximação do Brasil com os países da Ásia e, em especial, com a China, a partir de uma perspectiva histórica. No final do século XIX e início do XX, o relacionamento com esse continente foi ínfimo e restringiu-se basicamente à vinda de mão-de-obra japonesa e à migração não-oficial de chineses. Durante a Guerra Fria, sob a tentativa brasileira de diversificar suas parcerias, ocorre uma aproximação política com a China no plano multilateral, mas os laços econômicos bilaterais ficam restritos ao Japão. Apesar do tradicional discurso da diplomacia brasileira de universalização das suas relações internacionais, somente na década de 1990 houve de fato um fortalecimento da aproximação econômica, e não apenas política, com a China. Destacam-se como principais motivações o acelerado crescimento econômico chinês e a disputa comercial incitada pela proposta de criação de uma Área de Livre Comércio das Américas (Alca, entendida como um obstáculo para a inserção de atores externos.The present article analyses the Brazilian approach to the Asian countries, specially, to China, in a historical perspective. At the end of the 19th century and beginning of the 20th, the relationship with that continent was sparse and restricted basically to the coming of Japanese workers and to the non-official migration of Chinese. During the Cold War, under the Brazilian attempt to diversify its partnerships, there was a political approach to China on the multilateral sphere, nevertheless the economic ties stayed with Japan. Despite the traditional discourse of the Brazilian diplomacy about the universalization of the country's international relations, just at the 1990's there was in fact a strengthening of the economic approach to China and not only political. The main reasons were the Chinese high economic growth and the trade battle that was raised by the proposal for the creation of a Free Trade Area of

Estudios preliminares en esta especie han sugerido una elevada actividad antioxidante, un alto contenido fenólico y un gran potencial nutricional y funcional. En esta investigación se analizó la evolución de varios componentes del sistema de defensa antioxidante no enzimático, durante el crecimiento y maduración de los frutos de Psidium cattleianum Sabine. El periodo de crecimiento de los frutos presentó la actividad antioxidante más elevada, medida a través de las técnicas TEAC-DPPH y TEAC-ABTS (Trolox equivalent antioxidant capacity, FRAP (Ferric reducing/antioxidant powery ORAC (Oxigen Radical Absorbance Capacity, así como elcontenido máximo de fenoles totales, entre los que destacaron los ácidos clorogénico, cafeico y p-coumárico, y de sustancias no polifenólicas como el ácido ascórbico. Durante el periodo de maduración, se observó una disminución de la actividad antioxidante, posiblemente promovida por la pérdida gradual de algunos compuestos polifenólicos, así como también, debido a la aparición de otros compuestos como las antocianinas. Los resultados mostraron que estos frutos contienen un alto contenido de sustancias con actividad antioxidante, lo cual soporta el desarrollo de esta especie como nueva alternativa productiva / Abstract.

to analyze the frequency of hypoparathyroidism and of its recurrence after parathyroidectomy in dialysis patients according to different existing classifications. we conducted a retrospective study of 107 consecutive dialysis patients undergoing total parathyroidectomy with immediate autograft in a tertiary hospital from 2006 to 2010. We studied the changes in PTH levels in the postoperative period over time. Were grouped patients according to different PTH levels targets recommended according to the dosage method and by the American and Japanese Nephrology Societies, and by an International Experts Consortium. after parathyroidectomy, there was sustained reduction in serum calcium and phosphatemia. The median value of PTH decreased from 1904pg/ml to 55pg/ml in 12 months. Depending on the considered target level, the proportion of patients below the target ranged between 17% and 87%. On the other hand, the proportion of patients with levels above the target ranged from 3% to 37%. the application of different recommendations for PTH levels after parathyroidectomy in dialysis patients may lead to incorrect classifications of hypoparathyroidism or recurrent hyperparathyroidism and resultin discordant therapeutic conducts. analisar as frequências de hipoparatireoidismo e de recidiva do hiperparatireoidismo após paratireoidectomia em pacientes dialíticos de acordo com diferentes classificações existentes. estudo retrospectivo de 107 pacientes dialíticos consecutivamente submetidos à paratireoidectomia total com autoenxerto imediato em um hospital terciário no período de 2006 a 2010.

The porcelain-techniques creating its elegant and bright red-color underglaze and overglaze were found and developed in 1650's (early Edo period first by Kakiemon kiln. Red-color overglaze and transparent glaze of the Kakiemon-style porcelains have been investigated by means of X-ray diffraction using synchrotron radiation. The results suggest that the red-color brightness is mainly induced by micro-structural correlation between α-Fe2O3 fine particles, as red-color emission elements, and other oxides of SiO2, Al2O3, CaO, KNaO, PbO. The stability of the red-overglaze on the porcelain surface is related to interfacial fusion of the glasses existing in the fritted red-overglaze and the transparent glaze on the porcelain body. The ancient porcelain-techniques of the Kakiemon-style porcelains are clearly based on the micro-structural and material properties of the overglazes, the underglazes, and the transparent glazes, though the techniques were experimentally and accidentally found and developed in the Edo period.As porcelanas do estilo Kakiemon produzidas nas áreas de Arita (SAGA na ilha Kyushu são porcelanas japonesas famosas.

Full Text Available RESUMEN A lo largo del siglo XX la influencia de Japón en la arquitectura occidental ha tenido momentos destacados. Alison y Peter Smithson estudiaron las miradas al mundo japonés de las generaciones precedentes de arquitectos y subrayaron nuevos aspectos a considerar en él, relacionados con la estética de lo desechable y la cultura pop. La vivienda japonesa inspiró conceptualmente algunas de sus utopías domésticas, que influirían de manera especial en el grupo británico Archigram y, a través de ellos, en otros grupos radicales de los años sesenta. Los Smithson jugaron también un papel clave en la disolución de los CIAM en 1959 y en la creación del Team X. En ese último CIAM, participó Kenzo Tange presentando varios proyectos japoneses vanguardistas, dando comienzo a un rico periodo de intercambio de ideas entre occidente y Japón, que continuaría en la World Design Conference de Tokio, en 1960, y en posteriores encuentros del Team X . En el presente escrito la pareja británica sirve de hilo conductor, por su papel activo y crítico en todos estos encuentros. El artículo analiza esos momentos de conexión para establecer influencias mutuas, críticas, paralelismos y divergencias entre la arquitectura europea, personalizada en los Smithson, Archigram y el Team X, y los Metabolistas Japoneses a través de diversas escalas del diseño, desde lo doméstico a lo urbano.

Full Text Available Dificilmente se encontrará um outro país que foi tão influenciado por outras culturas e civilizações como o Japão. De fato, os grandes pontos de viragem da sua história foram marcados pelo encontro com outras civilizações e culturas. Porém, as grandes mudanças que se operaram como resultado de influências exteriores nunca conseguiram pôr em questão as premissas básicas da cultura japonesa. Prevaleceu sempre um sistema de valores que carece de uma clara orientação transcendental e universalista. Enquanto no mundo ocidental a dimensão transcendental do cristianismo exerceu uma forte influência na criação de valores universais à luz dos quais se configurou a realidade sociopolítica, no Japão o budismo, a religião dominante durante o período feudal, nunca conseguiu alcançar tal hegemonia e oferecer princípios orientadores para a ordem politica e social. O valor supremo ao qual tudo o resto se deve subordinar é a ordem sociopolítica da nação. Ser um membro fiel desta ordem e contribuir para a preservação da sua harmonia adquire um caráter quase sagrado. Aqui reside o núcleo essencial da religiosidade do povo japonês, frequentemente designada por Niponismo. Foi esta matriz cultural e religiosa de natureza etnocêntrica que permitiu ao Japão adotar muitos elementos da cultura ocidental para modernizar o país e manter, ao mesmo tempo, a sua própria identidade cultural.

Full Text Available Hay bastante confusión en los círculos políticos, académicos y también en los mercados con respecto a la situación económica internacional que se desencadenó por la crisis de 2007-2008. Y como hay tanta confusión, las respuestas de política económica han sido en gran parte inconsistentes, no solo en EEUU si no por todo el mundo, y esto puede estar prolongando innecesariamente la recesión. Sin embargo, lo que estamos viviendo actualmente ocurrió en Japón hace exactamente quince años. Lo que está pasando ahora, después del estallido de la burbuja, es que el sector privado se está desapalancando o reduciendo su deuda al mínimo. Esto se denomina recesión de balances. Y, en este tipo de recesión, recortar los tipos de interés al cero y aumentar la base monetaria no se traduce en una mejora del acceso al crédito del sector privado y en una recuperación de la actividad económica. La política monetaria se vuelve ineficaz. Tal y como muestra la experiencia japonesa, la respuesta para prevenir el colapso de la actividad económica reside en la política fiscal, esto es, el gobierno debe incrementar el gasto financiándose a si mismo con los ahorros que el sector privado genera al desapalancarse. Solo después de que los balances hayan sido saneados y el sector privado esté deseando, y pueda, endeudarse, puede empezar el gobierno a reducir su déficit presupuestario.There is quite a bit of confusion in the policy circles, in the academic circles and also in the markets regarding the international economic situation unleashed by the 2007-2008 crisis.

Objetivou-se analisar a viabilidade de um rebanho puro da raça Wagyu, em ciclo completo, entre os períodos de 2009 a 2013. A análise baseou-se nos indicadores econômicos: custo operacional total, receita bruta, margem bruta e margem líquida. A receita foi constituída pela venda de material genético, animais e carne. A média final da margem líquida foi positiva no valor de R$10.245,88 para o período. Porém, para o rebanho puro de Wagyu quando comparado por animal não mostrou-se vantajoso, pois o resultado foi menor devido aos altos investimentos em dois momentos, em 2009 e 2012. Contudo a comparação na comercialização, em R$/@, foi de 7,8 vezes superior a outros estudos. Estes ganhos evidenciam que se for feito ajustes para diminuir o custo ou aumentar a escala, os resultados futuros poderão ser muito promissores.

Full Text Available OBJETIVO: comparar do ponto de vista perceptivo-auditivo as características vocais dos gêneros do canto japonês enka e mudo enka. MÉTODOS: foram selecionadas dez gravações em CD comercialmente disponíveis de cinco cantores japoneses profissionais que caracterizam o gênero enka e cinco do estilo mudo enka. Foram elaborados um protocolo de avaliação de voz com características vocais encontradas nos dois estilos da música japonesa. A avaliação foi realizada por três fonoaudiólogas especialistas na área de voz pelo Conselho Federal de Fonoaudiologia, determinando as características vocais mais marcantes em cada gênero a partir da classificação baseada na literatura. RESULTADOS: no estilo enka, o kobushi, o vibrato e crescendos e decrescendos esteve presente em 100% das amostras vocais. Foi encontrado 80% de metal, 90% de nasalidade e alternância de registro e 70% de soprosidade. No estilo mudo enka, os crescendos e decrescendos esteve presente em 100% das amostras vocais. Foi encontrado 70% de soprosidade, 90% de vibrato, 50% de alternância de registro, 40% de metal e 20% de nasalidade e kobushi. CONCLUSÃO: Comparando-se os dois gêneros musicais, enka e mudo enka, identificou-se a presença marcante do Kobushi no gênero enka além do maior predomínio de vibrato, metal, nasalidade, alternância de registros e crescendos e decrescendos. A soprosidade foi encontrada em igual proporção em relação aos dois estilos musicais. A identificação das características vocais é útil ao fonoaudiólogo bem como ao professor de canto no atendimento de cantores durante o aprendizado do canto japonês e ou no aperfeiçoamento.PURPOSE: to compare from a perceptual perspective the vocal characteristics of enka and mudo enka Japanese singing genre.

Full Text Available RESUMEN Miguel Fisac, dispone un conjunto de piezas que recrean la esencia del paisaje manchego superando la simple copia de los arquetipos populares. El hueco entre dos tapias encaladas y una señal de carretera invitan al visitante del pabellón a iniciar un recorrido hacia la abstracción que nos sumergirá en un nuevo paisaje físico y mental. Mediante texto y dibujos propios, se reconstituye el desconocido pabellón, necesario eslabón en su obra del "periodo experimental" hoy lamentablemente desaparecido como otros de la Feria del Campo. En "La arquitectura popular manchega", investigación sobre la quintería, Fisac valora la arquitectura directa y sencilla, la lógica constructiva de los materiales disponibles con soluciones "puestas a prueba por el lento discurrir del tiempo". Alejandro de la Sota en el pabellón de Pontevedra y José Luis Romaní en el de Jaén, darán una respuesta estilística en el camino de experimentación moderna. Fisac elogia el pabellón de E. N. Rogers en la exposición de Bruselas de 1958 "...cómo contrapunto rabioso a tanta extravagancia arquitectónica sin contenido, Italia presenta un pabellón de arquitectura provinciana, casi rural", criticando la deriva moderna, el alarde estructural y el formalismo estéril. Pegando las edificaciones a los bordes y liberando el centro, Fisac utiliza el vacío como verdadero protagonista o materia de proyecto. Los horizontes y paisajes, el aire "delimitado" de la Alhambra y la casa japonesa son germen de su definición de arquitectura como "un trozo de aire humanizado". El objetivo es comprender y evidenciar aquellos principios esenciales con validez permanente aplicables, incluso hoy en día, al proyecto de arquitectura. SUMMARY Miguel Fisac, arranges a set of pieces that recreate the essence of the La Mancha landscape surpassing the simple imitation of the popular archetypes. The gap between two whitewashed walls, and a road sign invite the visitor to the pavilion to

Full Text Available OBJETIVO. Analizar factores de salud, laborales y sociales que contribuyen a renunciar al trabajo en dos maquiladoras transnacionales del ramo electrónico de Tijuana. MATERIAL Y MÉTODOS. Se realizó un estudio de cohorte a 725 mujeres empleadas en una planta japonesa y una estadunidense, entre enero de 1992 y marzo de 1994. La muestra se estratificó en dos intervalos de tiempo ­30 y >30 días laborados. Se efectuó un seguimiento de las mujeres hasta su renuncia o final del periodo de observación, mediante la recolección de información sobre variables de salud, sociales y ocupacionales de diversas fuentes de registro obtenidas de su centro de trabajo. Los motivos de renuncia y la confiabilidad de los datos obtenidos de los registros se estudiaron por medio de entrevistas de seguimiento realizadas a 46% (n= 148 de las trabajadoras que renunciaron y fueron localizadas aproximadamente 12 meses (desviación estándar= 6.7 después de su renuncia. RESULTADOS. La probabilidad acumulativa de renunciar al trabajo fue de 67% en el primer año y de 81% en el segundo. La ausencia de antecedentes laborales previos, turno diurno y nacionalidad de la compañía, resultaron factores predictivos para la renuncia al empleo durante los primeros 30 días. Tabaquismo, antecedentes quirúrgicos y haberse incapacitado por enfermedad general, después de controlar por otras variables, actuaron como factores predictivos para la renuncia posterior a 30 días. En contraposición, la tasa de renuncia posterior a 30 días resultó menor para mujeres con enfermedades crónicas. CONCLUSIONES. La renuncia al empleo en las maquiladoras es elevada y selectiva; en tanto que los factores ocupacionales se asociaron con la renuncia temprana, los relacionados con la salud fueron mejores factores predictivos para la renuncia posterior a los primeros 30 días.OBJECTIVE.

Full Text Available En 1977 el bioquímico inglés Frederick Sanger reportó un método para secuenciar moléculas de ADN, método que a la postre revolucionaría el área de la genómica y el entendimiento en general de la vida en nuestro planeta. Él demostró las bondades de su método al secuenciar completamente el genoma del fago Phi174 que contenía 5.836 pares de bases. Con esta técnica mejorada, se pudieron leer hasta 700 pares de bases en una sola reacción y fue utilizada masivamente para la secuenciación de genomas bacterianos, de levaduras, para finalmente, en 1990 desembocar en la propuesta de lectura de todo el genoma humano. Fueron muchos los que se opusieron al Proyecto Genoma Humano, sin embargo, contra todos los pronósticos se dio inicio bajo la dirección del premio nobel James D. Watson. Durante sus 13 años de desarrollo, el proyecto abrió muchos caminos, entre ellos, la bioinformática, ciencia que en 1990 era una empresa naciente, apenas en 1987 se había creado el GenBank en Estados Unidos, que sería a la postre el repositorio de todas las secuencias de ADN obtenidas hasta hoy día, teniéndose copias en la base de datos japonesa (DDBJ y europea (EMBL. Las tres diseminan libremente la información. Con el Proyecto Genoma Humano se desarrollaron a la par, las ómicas (proteómica, transcriptómica, metabolómica, farmacogenó-mica, epigenómica y lipidómica, etc.. El desarrollo de NGS (del inglés, Nex Generation Sequencing abrió un camino expedito para los proyectos ómicas. El método Sanger se utilizó automatizadamente con la posibilidad de hacer 96 o 384 lecturas en paralelo, lo que le imprimió al proyecto mayor rapidez en la obtención de secuencias, sin embargo, todavía resultaba un método demorado y costoso. En el proyecto se invirtieron 3 billones de dólares. Hoy día el costo de secuenciar 1 kb se estima en $0,5 US. Con NGS, también llamada secuenciación masiva en paralelo, la secuenciación en paralelo ha mejorado la

Full Text Available El cáncer gástrico es la segunda causa de muerte por cáncer en el mundo. Varios factores han sido asociados con el riesgo de llegar a desarrollarlo, entre ellos la predisposición genética. El gen p53 presenta un polimorfismo en el codón 72, el cual ha sido asociado con un mayor riesgo de desarrollar varios tipos de cáncer entre ellos el gástrico. El objetivo de este estudio fue determinar la asociación del polimorfismo localizado en el codón 72 del gen p53 con el riesgo de cáncer gástrico y lesiones gástricas leves en una población de alto riesgo de Costa Rica. El análisis del polimorfismo se llevó a cabo mediante PCR-RFLP, en una muestra de 58 pacientes de cáncer gástrico, 99 personas controles y 41 individuos clasificados como grupos I y II de acuerdo con la clasificación histológica japonesa. No se determinó asociación del polimorfismo del codón 72 de p53 con el riesgo de cáncer gástrico, ni de lesiones gástricas leves en la muestra estudiada. Con base en este estudio y otros que han investigado el polimorfismo del codón 72 del gen p53, no está claro el papel que podría estar jugando dicho polimorfismo en el desarrollo de cáncer gástrico. Mutaciones de novo en el gen p53 producidas durante el desarrollo neoplásico de la enfermedad podrían tener un mayor efecto que polimorfismos de línea germinal de este mismo gen. Existen otros genes polimórficos que también se han asociado con el riesgo de desarrollar cáncer gástrico.Association of the p53 codon 72 polymorphism to gastric cancer risk in a hight risk population of Costa Rica.

Full Text Available The percentual distributions of selected sites of cancer cases according to origin, sex and age are compared. Data were obtained from the Registry of Cancer of S. Paulo (School of Public Health of the University of S. Paulo, Brazil. The reference period for inhabitants of Japanese descent was 1969/78 and for those of Brazilian descent, the period was 1969/75. Standardized Proportionate Incidence Ratios (SPIR with approximate 95% Confidence Intervals (CI were evaluated using age specific Incidence Ratios of S. Paulo, 1973, as standards. The results agree with findings of previous works on mortality, but show different patterns according to origin. The well known fact that some sub-groups of a population may be different from the overall group is once again brought to the fore. Attention should be drawn to the differences detected for stomach, skin and prostate, in males, and for stomach, skin, cervix and uterus in females.São comparadas as distribuições percentuais dos casos de câncer de algumas localizações anatômicas segundo país de nascimento, sexo e idade. Os dados foram coletados no Registro de Câncer de São Paulo da Faculdade de Saúde Pública da USP, referentes aos períodos 1969-1978, para os japoneses, e 1969-1975, para os brasileiros. Razões padronizadas de incidência proporcional e respectivos intervalos com 95% de confiança foram calculados, usando como padrão a incidência proporcional específica por idade de São Paulo, em 1973. Os resultados, consistentes com trabalhos anteriores relativos à mortalidade, mostraram haver possíveis padrões distintos de incidência de câncer em japoneses e brasileiros. Chamou atenção para o fato de que alguns sub-grupos de uma população apresentam comportamentos diferentes e, no presente caso, principalmente quanto à incidência de cânceres de estômago, próstata, pele, em homens, e estômago, pele, colo uterino e útero, em mulheres.

Full Text Available The aim of this study was to investigate whether protein supplementation helps prevent the loss of fat-free mass during weight loss. The sample was composed of seventy-eight obese adult Japanese women, assigned into four different programs: diet-alone (D, n=24, diet-alone with protein supplementation (DP, n=16, diet-plusexercise (DE, n=17, and diet-plus-exercise with protein supplementation (DEP, n=21. All participants restricted their energy intakes to 1200 kcal/day, and participants in DE and DEP had the exercise session including aerobic exercise of approximately 90 min/day, 3 day/week. Participants enrolled in protein supplementation groups received an additional 14 g/day of protein. Measures on body composition were conducted before and after the program by DXA. All programs yielded significant weight (6.9 to 9.5 kg and fat (4.1 to 7.6% reduction. Total fat-free mass significantly decreased in D, DP and DE groups, whereas for DEP group the decrease was not significant. Regionalfat-free mass lowered for D and DP groups in leg, arms and trunk. For those in DE group, fat-free mass in trunk was not significantly decreased, and for those in DEP group, fat-free mass in leg and trunk did not differ significantly after the program. However, no significant differences of changes in fat-free mass were observed in comparisons among all groups. Our results confirmed the efficiency of weight loss intervention on fat-mass reduction through diet and exercise. However, fat-free mass does not appear to be preserved by protein supplementation, suggesting that its influence on a short-term weight reduction program is not apparent. RESUMO O objetivo deste estudo foi investigar a influência da suplementação protéica na preservação da massa magra durante programas de emagrecimento.

Barrett's esophagus should be followed up for the possibility of progression to malignancy, especially when the segment is longer than 3 cm.O esôfago de Barrett é definido como a substituição do epitélio escamoso do esôfago distal por epitélio colunar. A metaplasia intestinal no esôfago de Barrett é considerada por muitos como o principal fator de risco para o desenvolvimento do adenocarcinoma. Embora já descrito, o adenocarcinoma do tipo difuso e o esôfago de Barrett sem metaplasia intestinal, são raros e pouco estudados. OBJETIVO E MÉTODO: O presente estudo objetivou o cálculo da prevalência do adenocarcinoma no esôfago de Barrett, assim como a análise macroscópica e microscópica detalhada de treze pacientes operados no período de 1990 a 2002, com realização de estudo imunohistoquímico do p53 e Ki67, correlacionando o tipo de tumor com o epitélio adjacente a este. RESULTADOS: Obtivemos uma prevalência de 5,7% de adenocarcinoma em pacientes internados para tratamento cirúrgico de esôfago de Barrett . Encontraram-se tumores relativamente grandes, com média de 4,67 ± 2,28 cm, e sempre em esôfago de Barrett longo, com média de 7,71 ± 1,5 cm. Observou-se tendência de os tumores se localizarem próximos à transição escamo-colunar. O estudo histológico mostrou dois pacientes (15,4% que apresentavam esôfago de Barrett adjacente ao tumor do tipo juncional sem presença de metaplasia intestinal. Classificaram-se os tumores segundo a classificação japonesa de Nakamura (23% de padrão diferenciado ou intestinal e 77% de padrão indiferenciado ou gástico e pela classificação de Laurén (61% intestinais e 39% difusos. A diferença decorre da migração dos tumores microtubulares e foveolares do padrão gástrico para o tipo intestinal de Laurén. O estudo do Ki67 foi fortemente positivo em todos os pacientes, mostrando o alto índice de proliferação celular no epit

mejor para nuestra gente.

Cuando me gradué en la Facultad de Medicina de Buenos Aires, abrí mi consultorio en un barrio periférico de la ciudad. Era lo que allí denominamos un médico de barrio, un clínico que atendía las necesidades de mi comunidad viendo adultos, niños, embarazadas, familias enteras con las que convivía en un mismo ámbito ciudadano. Veía pacientes en el domicilio y muchas veces me despertaban por la noche para atender una emergencia. Tuve que hacer el parto de la tintorera japonesa de mi barrio, que no hablaba español, cuyo hijo me vino a buscar porque la madre se sentía indigestada al parecer porque le había caído mal alguna comida. Cuando entré me encontré con una señora obesa, con un abdomen globuloso con contracciones frecuentes y le pregunté si sabía que estaba embarazada; nunca pude oír lo que me contestó porque el niño ya venía. Para cerrar esta anécdota les cuento que horas después nacía el segundo de los mellizos, producto de la famosa indigestión. Como ustedes ven hacía medicina general de barrio o de pueblo y, les aseguro, con buen éxito de pacientes.

Trabajaba por la mañana en un hospital en el que funcionaban cátedras de la Facultad y allí nació mi interés por la enseñanza. Por supuesto, cuando quise abrazar la carrera docente debí optar por una de las ramas de la medicina y elegí la que más se aproximaba a mi tarea, lo que en mi país se llama Clínica Médica, equivalente a lo que en otras partes denominan Medicina Interna. No existía una cátedra de Medicina General, como la practicaban cientos de médicos de entonces, sencillamente porque la Medicina General en el ámbito de la educación médica era una especie en extinción.

Bastantes años después, me puse en contacto con el pujante movimiento de Family Practice que estaba en franco ascenso en los Estados Unidos, y allí me reencontré con un campo que me era muy familiar. Pensé de inmediato que si ese tipo de medicina ten

-à-face avec leur opposant avant de prendre leur décision. De plus, les participants de la condition entre groupes avaient également la possibilité de converser librement avec les membres de leur propre groupe. Les résultats se sont révélés semblables à ceux des études antérieures réalisées aux États-Unis; les groupes ont fait des choix plus compétitifs que les individus. En outre, ni la magnitude de l'effet de discontinuité, ni la fréquence des choix compétitifs faits par les groupes n'étaient plus grands chez les Japonais comparativement à la majorité des études antérieures menées aux États-Unis. Ces résultats soutiennent la robustesse interculturelle de l'effet de discontinuité entre les individus et entre les groupes. Aussi, fait intéressant, ils contredisent la simple distinction entre l'individualisme et le collectivisme. Les implications pour des études sur les cultures et les processus de groupe sont discutées. El efecto de discontinuidad entre individuos y entre grupos es la tendencia a que las relaciones entre grupos sean más competitivas que las relaciones entre individuos. Se ha observado con insistencia en estudios conducidos en Estados Unidos, una sociedad caracterizada como "individualista". En el presente estudio, se exploró si el efecto se repetía en una sociedad "colectivista" como la japonesa. Desde la perspectiva tradicional de la psicología trans cultural, que subraya la naturaleza colectivista de los pueblos asiáticos, se esperaba que el efecto de discontinuidad fuese mayor en Japón que en Estados Unidos. Por otra parte, con base en los hallazgos empíricos recientes que sugieren que los estadounidenses no están menos orientados al grupo que los de este asiático, se esperaba que el efecto de discontinuidad no fuera mayor en Japón que en los Estados Unidos. Ciento sesenta estudiantes universitarios japoneses participaron en un juego del dilema de un prisionero de diez ensayos repetidos: veintiséis sesiones entre
