  1. The female guinea pig, a useful model for the genetic hazard of radiation in man; preliminary results on germ cell radiosensitivity in foetal, neonatal and adult animals

    International Nuclear Information System (INIS)

    A comparison was made of the radiosensitivities of the resting oocyte of guinea pig in its two different states, the 'large' resting and 'contracted' oocyte, also extending the investigations to the radiosensitivity of the female germ cells at earlier stages during intrauterine life. Irradiation induced a dose-dependent decrease in the total number of oocytes, and this effect was more pronounced in animals irradiated as adults (target cells: contracted resting oocytes). Our results also suggested that the LD50 of the large guinea pig resting oocyte should be around 4 Gy, a value similar to that obtained recently for the equivalent human oocyte. This confirms the high radioresistance of the guinea pig oocyte and the consequent suitability of this species for further detailed studies in relation to genetic hazards in man. (author)

    This study was carried out to compare potential methods of transplanting adult Oesophagostomum dentatum from experimentally infected donor pigs to helminth naive recipient pigs. The following methods were each tested in five pigs: A. Transfer of worms by stomach tube to the gastric ventricle of pigs per os pretreated with 0.5 mg/kg cisapride to increase gastrointestinal peristalsis; B. Transfer by stomach tube to the gastric ventricle of pigs per os pre-treated with cisapride (0.5 mg/kg) and omeprazol 20 mg which blocks hydrochloric acid secretion; C. Surgical transfer of worms to caecum of pigs. Worms for transplantation to pigs were obtained after slaughter of experimentally infected donor pigs and following isolation from the contents of the large intestine, using an agar gel migration technique. A mean of 1054 nematodes were transferred into each recipient pig within 2 hours. Procedures A and B resulted in establishment rates corresponding to only 0.5% and 7.6% of the transferred worms. In contrast, surgical transfer allowed 74.2% of the transplanted worms to be established. In all groups the transplanted worms migrated to the normal predilection site, i.e. the middle part of the large intestine. More female than male worms established in all groups. It was concluded from this study that surgical transfer was the most reliable of the methods tested for experimental establishment of adult O. dentatum in helminth naive pigs. PMID:8583123

    Full Text Available In several rodent species, an increase or recovery of sexual behavior can be observed when sexually satiated males are placed in contact with a novel mate. In order to assess the influence of female novelty on the courtship behavior of guinea pigs (Cavia porcellus, four adult males were observed during four daily 15-min sessions while interacting with the same pregnant female (same-female sessions. A new female was presented during the fifth session (switched-female session. The duration of behavioral categories was obtained from videotape records using an observational software. From the first to the second session, all males decreased the time allocated to investigating (sniffing and licking, following, and mounting the female, and that response did not recover by the end of the same-female sessions. No similar decreasing tendencies were detected in the circling or rumba categories. A marked increase of investigating occurred in all males from the last same-female session (8.1, 11.9, 15.1 and 17.3 percent session time to the switched-female one (16.4, 18.4, 37.1 and 28.9 percent session time, respectively. Increases in following and circling were recorded in three of four males, and full-blown recovery of mounting in one male. No consistent changes in the females' responses to males (following or attacking were observed throughout testing. These results are consistent with the hypothesis that guinea pig males recognize individual females and that courtship responses may suffer a habituation/recovery process controlled by mate novelty.

    Immunization of male and female animals with extracts of whole sperm cells is known to cause infertility. Also, men and women who spontaneously produce antisperm antibodies are infertile but otherwise healthy. Although the critical sperm antigens are unknown, these observations have led to the proposal that sperm proteins might be useful in the development of a contraceptive vaccine. The guinea pig sperm surface protein PH-20 is essential in sperm adhesion to the extracellular coat (zona pellucida) of the egg, a necessary initial step in fertilization. Here, we report that 100% effective contraception was obtained in male and female guinea pigs immunized with PH-20. Antisera from immunized females had high titres, specifically recognized PH-20 in sperm extracts, and blocked sperm adhesion to the egg zona pellucida in vitro. The contraceptive effect was long-lasting and reversible: immunized females, mated at intervals of six to fifteen months after immunization, progressively regained fertility. PMID:3419530

    The discrete effects of obesity on infertility in females remain undefined to date. To investigate obesity-induced ovarian dysfunction, we characterized metabolic parameters, steroidogenesis, and folliculogenesis in obese and lean female Ossabaw mini-pigs. Nineteen nulliparous, sexually mature female Ossabaw pigs were fed a high fat/cholesterol/fructose diet (n=10) or a control diet (n=9) for eight months. After a three-month diet-induction period, pigs remained on their respective diets and had ovarian ultrasound and blood collection conducted during a five-month study period after which ovaries were collected for histology, cell culture, and gene transcript level analysis. Blood was assayed for steroid and protein hormones. Obese pigs developed abdominal obesity and metabolic syndrome, including hyperglycemia, hypertension, insulin resistance and dyslipidemia. Obese pigs had elongated estrous cycles and hyperandrogenemia with decreased LH, increased FSH and luteal phase progesterone, and increased numbers of medium, ovulatory, and cystic follicles. Theca cells of obese, compared to control, pigs displayed androstenedione hypersecretion in response to in vitro treatment with LH, and up-regulated 3-beta-hydroxysteroid dehydrogenase 1 and 17-beta-hydroxysteroid dehydrogenase 4 transcript levels in response to in vitro treatment with LH or LH + insulin. Granulosa cells of obese pigs had increased 3-beta-hydroxysteroid dehydrogenase 1 transcript levels. In summary, obese Ossabaw pigs have increased transcript levels and function of ovarian enzymes in the delta 4 steroidogenic pathway. Alterations in LH, FSH, and progesterone, coupled with theca cell dysfunction, contribute to the hyperandrogenemia and disrupted folliculogenesis patterns observed in obese pigs. The obese Ossabaw mini-pig is a useful animal model in which to study the effects of obesity and metabolic syndrome on ovarian function and steroidogenesis.

    2000-04-01

    The present study used the theory of planned behavior (TPB) (Ajzen, 1985) augmented by AIDS knowledge to investigate factors influencing intentions of Hispanic adults to use the female condom. A total of 146 persons (75 women and 71 men; mean age, 27 years) recruited from community-based organizations completed an anonymous survey regarding intentions to use the female condom with their main sex partner. The TPB model had greater predictive utility for women's, than for men's, female condom use intentions. For men, attitudes and norms did not predict female condom use intentions, but greater AIDS knowledge was related to lower intentions to use the female condom, above and beyond the TPB constructs. Perceived behavioral control, operationalized as self-efficacy, significantly increased the predictive utility of the TPB model for women's female condom use intentions but not for men's. Behavior change strategies to increase female condom use are discussed in light of these findings. PMID:10833679

    Cryptosporidium spp., ubiquitous enteric parasitic protozoa of vertebrates, recently emerged as an important cause of economic loss and zoonosis. The present study aimed to determine the distribution and species of Cryptosporidium in post-weaned and adult pigs in Shaanxi province, northwestern China. A total of 1,337 fresh fecal samples of post-weaned and adult pigs were collected by sterile disposable gloves from 8 areas of Shaanxi province. The samples were examined by Sheather's sugar flotation technique and microscopy at × 400 magnification for Cryptosporidium infection, and the species in positive samples was further identified by PCR amplification of the small subunit (SSU) rRNA gene. A total of 44 fecal samples were successfully amplified by the nested PCR of the partial SSU rRNA, with overall prevalence of 3.3%. The average prevalence of Cryptosporidium infection in each pig farms ranged from 0 to 14.4%. Species identification by sequencing of SSU rRNA gene revealed that 42 (3.1%) samples were Cryptosporidium suis and 2 (0.15%) were Cryptosporidium scrofarum. C. suis had the highest prevalence (7.5%) in growers and the lowest in breeding pigs (0.97%). C. suis was the predominant species in pre-weaned and adult pigs, while C. scrofarum infected pigs older than 3 months only. A season-related difference of C. suis was observed in this study, with the highest prevalence in autumn (5.5%) and the lowest (1.7%) in winter. The present study provided basic information for control of Cryptosporidium infection in pigs and assessment of zoonotic transmission of pigs in Shaanxi province, China. PMID:25748718

    Objective: To communicate the presence of adult females, rabditoid larvae and eggs of Strongyloides stercoralis (S. stercoralis) in the respiratory secretions obtained by tracheal aspirate from a HIV-negative patient who was suffering from polymyositis, and treated with corticoids and amethopterin and assisted by pneumonia. Methods: The respiratory secretions submitted to the Parasitology Laboratory of the Muñiz Hospital were made more concentrated by centrifugation (1 500 r/min for 15 seconds). Wet mount microscopy was performed with the pellet. Results: It revealed adult females, rabditoid larvae and eggs of S. stercoralis. Further parasitological studies performed after the start of the treatment with ivermectin on fresh fecal samples, gastric lavages and tracheal aspirates showed scanty mobile filariform and rabditoid larvae of the same parasite. Conclusions: The presence of adult female S. stercoralis which has never been observed before in the clinical samples submitted to our Laboratory for investigation can be considered as an indirect marker of the severe immunosupression of the patient.

    Full Text Available Background : Acne, the most common problem that presents to dermatologists, can persist beyond teen years. Although its physical and psychosocial impact is studied in teen years, it is poorly understood in the Indian adult population. Aim : To study the physical and psychosocial impact of acne in adult females. Settings and Design : This exploratory study was done in the university setting. Materials and Methods : Eleven adult, unmarried females, between the age group of 18 and 25 years, having (mild-to-moderate, acne, for two consecutive years, were interviewed using a semi-structured clinical interview of the Skindex, a quality-of-life measure for patients with skin disease, developed by Chren et al., along with some open-ended questions. Both qualitative and quantitative analysis was done to analyze the data. Results : The results indicated a higher level of emotional and social impairment, in terms of the feelings of physical discomfort, anger, and the intermingling impact of these, among the participants. Conclusions : Acne is a common problem among adults and appears to have a considerable impact on the mental health, therefore, for the treatment to be successful, a sympathetic approach by doctors and significant others, with the basic psychosomatic treatment, are necessary.

  9. Sex peculiarities of radiosensitivity. Communication 4. Action of ionizing radiation on the sexual cycles of mouse and guinea pig females

    International Nuclear Information System (INIS)

    Animals (mice, guinea pigs) were irradiated with doses of 500, 700 and 750 r, while a control group was subjected to mock radiation. In all cases after mock and real irradiation, the sexual cycles of the female mice and guinea pigs were disturbed after 1-3 hours (after mock irradiation slightly, and after irradiation doses of 500 and 700 r to a greater extent). The restoration of the cycles of some animals after mock irradiation took place after 2 - 3 days, and of others after 10 - 14 days. After irradiation with doses of 500 - 700 r restoration of the cycles did not occur for two months and longer. Despite the considerable individual differences in the duration of the reaction, the delay was observed in all mice principally in the phase after heat, and in the guinea pigs during the inactive phase.

  11. Electrophoretic pattern of 14C-glucose labelled microsomal glycoproteins in embryonic and adult pig liver

    International Nuclear Information System (INIS)

    The microsomal fractions of 55-day-old and adult pig liver incubated with UPD 14C-glucose are used for extraction of the glycolipids. The solubilized protein was separated by vertical electrophoresis and the number and By electrophoretic analysis it is shown the presence of a major fraction with molecular mass about 50 kD in adult liver, which is decreased in quality in embryonic liver. Several fractions of different molecular masses in the adult pig liver were also observed, which are lost in the embryonic tissue or are present in a much smaller quantity. By means of SDS-polyacrylamide gel electrophoresis six radioactive peaks, including two highly extended fractions, were found. The radioactive labelling is significantly low in embryonic liver microsomal proteins with two peaks only. It can be assumed that in the embryonic liver acceptor proteins on which the major lipid oligosaccharide is transferred though more weakly labelled are more numerous than the ones in the adult pig liver. 1 fig., 6 refs

  12. Could adult female acne be associated with modern life?

    In recent years, the prevalence of adult female acne has increased, but the reason for this increase remains unclear. Acne is one of the most common skin disorders. It can be triggered or worsened by endogenous and exogenous factors, including genetic predisposition, hormone concentrations, diet, smoke and stress; although the interaction with this last factor is not well understood. Modern life presents many stresses including urban noises, socioeconomic pressures and light stimuli. Women are especially affected by stress during daily routine. The recent insertion in the labor market is added to the duties of the mother and wife. Women also have a higher risk of developing psychiatric disorders such as depression and anxiety. Sleep restriction is added to these factors, with several negative consequences on health, including on hormonal secretion and the immune system. This is further complicated by the natural variation in sleep architecture across the menstrual cycle. Recent studies have brought new data about the mechanisms and possible factors involved. This review aims to establish a connection between stress, sleep deprivation and adult female acne. PMID:24952024

  13. Predictors of urinary cadmium levels in adult females

    International Nuclear Information System (INIS)

    Ubiquitous exposure to low levels of cadmium has raised concern about adverse health effects. The aim of this study was to identify characteristics of non-occupationally exposed adult females that correlated with creatinine-adjusted urinary cadmium levels. In our population-based study, trained interviewers collected information from 254 female Wisconsin residents aged 20-69 years on tobacco use, limited dietary consumption patterns, reproductive history, demographics, and residential history. Participants provided spot-urine specimens collected at home. Urine cadmium concentrations were quantified using inductively-coupled plasma mass spectrometry and creatinine levels were also determined. Least square means and 95% confidence intervals for the natural log of the creatinine-adjusted urinary cadmium levels were calculated for each characteristic using multivariate analysis of variance adjusting for age and smoking status. Results were calculated on the log scale and then transformed to the original scale by taking the exponent of each of the values. We observed statistically significant increasing creatinine-adjusted urinary cadmium mean levels relative to smoking status, older age, parity, lower body surface area, mineral zinc supplement consumption, and high income. We did not observe a difference relative to consumption of organ meats, crustaceans, alcohol, multivitamins, multiminerals or homegrown vegetables, age of menopause, menarche of participant or oldest daughter, menopausal status or urban-rural residential location. Approximately 40% of the variance in creatinine-adjusted urinary cadmium levels in adult women was explained by several characteristics. Similar to other studies, age and smoking were the strongest determinants of creatinine-adjusted urinary cadmium concentration

    It is unclear whom animals select to huddle with for thermoregulation. In this study, we investigated whom Japanese macaque (Macaca fuscata) mothers huddled with-their young offspring or other adult group members-when there is need for thermoregulation. We used a focal-animal sampling method, targeting 17 females at Katsuyama, Okayama Prefecture, Japan. A majority of huddling among adult females was recorded during winter season (December, January, and February). Females who had young (0- or 1-year-old) offspring huddled less frequently with other adult females compared to females who did not have young offspring in winter. However, including young offspring, the frequency of huddling with any other individuals did not differ by whether females had young offspring. Moreover, the females who did not have young offspring huddled with other adult females more often in cloudy than in sunny weather during winter season. In contrast, females who had young offspring increased huddling with their young offspring in cloudy than in sunny weather, but did not do so with other adult females. This study indicates that Japanese macaque mothers huddle with their young offspring instead of other adult females when there is need for thermoregulation. PMID:27262980

    Butyrylcholinesterase (BChE) degrades acetylcholine in addition to acetylcholinesterase (AChE) which is involved in embryonic development of limbs. Since BChE is expressed by osteoblast-like cells we asked whether it is functional in adult bone remodeling. We addressed this issue by analyzing BChE gene-deficient mice (BChE-KO). Bones were extracted from 16-week old female BChE-KO and corresponding wild type mice (WT). Femoral bones were used for biomechanical testing and μCT evaluation of cancellous and cortical bone. Also vertebrae Th12 and L1 were investigated with μCT while L3 was used for tartrate-resistant acidic phosphatase (TRAP) histomorphometry and Th10 for gene expression analysis by means of real-time RT-PCR. BChE-KO did not reveal significant differences in biomechanical bone strength and bone mineral density determined by μCT. Microarchitecture of cancellous and cortical bone showed an increase in μCT parameters like trabecular thickness, trabecular separation, and relative cortical bone area of femoral BChE-KO bone compared to WT. In vertebrae no changes of microstructure and mRNA expression were detected. However, osteoclast histomorphometry with TRAP stained sections demonstrated a significant increase in relative osteoclast number. In conclusion, in adult murine bone the role of BChE is limited to bone specific changes in microarchitecture and to an increase in relative number of bone resorbing osteoclasts whereas the main collagen resorbing enzyme Cathepsin-K (CtsK) was stably expressed. Besides, AChE might be able to compensate the lack of BChE. Thus, further analyses using bone tissue specific AChE BChE cre-lox double knockout mice would be helpful. PMID:26138460

    The pig pancreas is considered to be one of the most suitable sources of islets for clinical xenotransplantation. However, after producing α1-3galactosyltransferase knockout pigs, most of the organs of these pigs showed less antigenicity to the human body. Wild-type adult pig islets (APIs) that originally produced negligible levels of α-Gal, different from neonatal porcine islet-like cell clusters, showed a clear antigenicity to human serum. Concerning the so-called non-Gal epitopes, many studies related to glycoproteins and glycolipids are ongoing in efforts to identify them. However, our knowledge of non-Gal glycoantigens remains incomplete. In our previous study, N-glycans were isolated from APIs, and the structures of 28 of the N-glycans were detected. In this study, to identify additional structures, further analyses were performed by liquid chromatography-mass spectrometry (LC-MS). N-glycans were isolated from APIs by the method described by O'Neil et al with minor modifications and LC-MS-based structural analyses were then performed. The detected N-glycan peaks in the LC-MS spectra were selected using the FLexAnalysis software program and the structures of the glycans were predicted using the GlyocoMod Tool. The API preparation contained 11 peaks and 16 structures were then nominated as containing N-linked sugars. Among them, 5 sulfated glycans were estimated, confirming the existence of sulfate structures in N-glycans in API. In addition, these data may supplement several N-glycan structures that contain two deoxyhexose units, such as fucose, to our previous report. The data herein will be helpful for future studies of antigenicity associated with API. PMID:27320609

Methods  One hundred and seventy-four adult females were included in the cross-sectional study from Mar. to Sep. 2006 through a simple random sampling from a group of population subjected to routine physical examination in the Luohuang Community of Chongqing municipality. The anthropometric measurements, blood pressure (BP, uric acid (UA, lipid profile, glucose and insulin levels were measured. Lipid accumulation product (LAP, body mass index (BMI and the homeostasis model assessment of insulin resistance (HOMA-IR were calculated. Subjects were divided into normal group and hyperuricemia group based on their UA levels, and an independent-samples t test was performed for comparison between the two groups; one-factor analysis of variance was performed for multiple comparisons. The Student-Newman-Keuls test was performed for homogeneity of variance. The relationship between UA and other variables was analyzed by Pearson correlation analysis and multiple linear stepwise regression analysis. Logistic regression analysis was used to determine the odds ratio of hyperuricemia in the highest quartile of LAP level. The analysis of the areas under the receiver operating characteristic (ROC curves was performed to identify the predictive ability of relevant variables to hyperuricemia. Results  Compared with normal group, the age, waist circumference (WC, triglyceride (TG, fasting insulin (FINS, HOMA-IR and LAP were higher in hyperuricemia group (P<0.05.

    This study describes young adult female college students' perceptions of risky social media behaviors. A sample of 14 young adult females, aged 18-22 years and residing in an urban university, participated in 1 of 3 focus groups held in campus housing. Data analysis yielded 4 themes surrounding young adults' engagement in risky behaviors associated with social media. Themes described the predominant culture, associated risk, and prevention. Important insights into young adult female college students' thoughts on risky social media behaviors can be used by advanced practice nurses to inform preventive education for young college women.

    The characterization and potential of mesenchymal stem cells (MSCs) are gender dependent and estrogen influences these properties. This study demonstrated that supplementation with 17β-estradiol (E2) increases the proliferation of bone marrow-MSCs derived from male and female mini-pigs (Mp- and Fp-BMSCs) in a concentration-dependent manner, with 10(-12) M E2 suggested as the optimal dose of E2 that led to the greatest improvement in BMSCs proliferation. Supplementation of 10(-12) M E2 resulted in down-regulation of β-galactosidase activity and pro-apoptotic activity in both BMSCs, while anti-apoptotic activity was up-regulated in only Fp-BMSCs. Further, E2 increased the osteogenic ability of Fp-BMSCs. Based on these findings, optimal utilization of E2 can improve cellular senescence and apoptosis, as well as in vitro osteogenesis of BMSCs, and could therefore be useful in stem cell therapy, particularly in bone regeneration for adult females.

    The current situation of organ transplantation is mainly determined by the disbalance between the number of available organs and the number of patients on the waiting list. This obvious dilemma might be solved by the transplantation of porcine organs into human patients. The metabolic similarities which exist between both species made pancreatic islets of Langerhans to that donor tissue which will be most likely transplanted in human recipients. Nevertheless, the successful isolation of significant yields of viable porcine islets is extremely difficult and requires extensive experiences in the field. This review is focussing on the technical challenges, pitfalls and particularities that are associated with the isolation of islets from juvenile and adult pigs considering donor variables that can affect porcine islet isolation outcome.

    2006-03-01

    Full Text Available Abstract Background Zygote arrest 1 (ZAR1 is one of the few known oocyte-specific maternal-effect genes essential for the beginning of embryo development discovered in mice. This gene is evolutionary conserved in vertebrates and ZAR1 protein is characterized by the presence of atypical plant homeobox zing finger domain, suggesting its role in transcription regulation. This work was aimed at the study of this gene, which could be one of the key regulators of successful preimplantation development of domestic animals, in pig and cattle, as compared with human. Methods Screenings of somatic cell hybrid panels and in silico research were performed to characterize ZAR1 chromosome localization and sequences. Rapid amplification of cDNA ends was used to obtain full-length cDNAs. Spatio-temporal mRNA expression patterns were studied using Northern blot, reverse transcription coupled to polymerase chain reaction and in situ hybridization. Results We demonstrated that ZAR1 is a single copy gene, positioned on chromosome 8 in pig and 6 in cattle, and several variants of correspondent cDNA were cloned from oocytes. Sequence analysis of ZAR1 cDNAs evidenced numerous short inverted repeats within the coding sequences and putative Pumilio-binding and embryo-deadenylation elements within the 3'-untranslated regions, indicating the potential regulation ways. We showed that ZAR1 expressed exclusively in oocytes in pig ovary, persisted during first cleavages in embryos developed in vivo and declined sharply in morulae and blastocysts. ZAR1 mRNA was also detected in testis, and, at lower level, in hypothalamus and pituitary in both species. For the first time, ZAR1 was localized in testicular germ cells, notably in round spermatids. In addition, in pig, cattle and human only shorter ZAR1 transcript variants resulting from alternative splicing were found in testis as compared to oocyte. Conclusion Our data suggest that in addition to its role in early embryo

    Full Text Available The androgen insensitivity (testicular feminization syndrome was described by Morris in phenotypic females with 46XY karyotype, presenting with primary amenorrhea, adequate breast development, and absent or scanty pubic or axillary hair. Gonads consist usually of seminiferous tubules without spermatogenesis. These patients have a 5-10% risk of developing germ cell tumors, usually after the complete development of secondary female sexual characteristics. We hereby report a case considered as a female with married life of 15 years, who was operated for severe abdominal pain. Phenotype characters were that of female. Microscopic examination of the tumor from the abdomen revealed germinoma and yolk sac tumor with adjacent seminiferous tubules. Karyotyping showed 46XY. Final diagnosis of malignant mixed germ cell tumor in androgen insensitivity syndrome was made. Surveillance may be the most appropriate option when these conditions are initially diagnosed in adulthood to prevent development of germ cell tumors.

    Full Text Available Abstract Background In parent-offspring communication, vocal signals are often used to attract attention and offspring might call to induce parental behaviour. In guinea pigs (Cavia aperea f. porcellus mothers wean larger litters later than small ones, but it is unknown whether this difference depends on processes induced during pregnancy or is influenced post-natally by the number of pups present. We here tested with playback-experiments using pup separation calls whether mothers with cross-fostered large experimental litters (four-pup-litters were more responsive to offspring calls and maintained responsiveness for longer than mothers with small experimental litters (two-pup-litters. Mothers were tested when two pups were suckling i.e. when both teats were occupied. Results Mothers of four-pup litters responded stronger to broadcast pup separation calls than those with two-pup litters. Additionally, we tested the mothers' responsiveness to pup separation calls in the absence of their pups on day 8 and 20 of lactation. Mothers of four-pup litters responded stronger and showed no decrease in responsiveness from day 8 to 20, whereas mothers of two-pup litters responded less and decreased responsiveness from day 8 to 20. Mothers of four-pup litters also weaned their pups 5 days later than those of two-pup litters. Conclusion Measured by their response to pup calls and by time to weaning, guinea pig mothers adjust maternal responsiveness to litter size. This behaviour is likely to be an adaptive strategy in resource allocation during reproduction.

  11. Virtual fetal pig dissection as an agent of knowledge acquisition and attitudinal change in female high school biology students

    Science.gov (United States)

    Maloney, Rebecca Scudari

    One way to determine if all students can learn through the use of computers is to introduce a lesson taught completely via computers and compare the results with those gained when the same lesson is taught in a traditional manner. This study attempted to determine if a virtual fetal pig dissection can be used as a viable alternative for an actual dissection for females enrolled in high school biology classes by comparing the knowledge acquisition and attitudinal change between the experimental (virtual dissection) and control (actual dissection) groups. Two hundred and twenty-four students enrolled in biology classes in a suburban all-girl parochial high school participated in this study. Female students in an all-girl high school were chosen because research shows differences in science competency and computer usage between the genders that may mask the performance of females on computer-based tasks in a science laboratory exercise. Students who completed the virtual dissection scored significantly higher on practical test and objective tests that were used to measure knowledge acquisition. Attitudinal change was measured by examining the students' attitudes toward dissections, computer usage in the classroom, and toward biology both before and after the dissections using pre and post surveys. Significant results in positive gain scores were found in the virtual dissection group's attitude toward dissections, and their negative gain score toward virtual dissections. Attitudinal changes toward computers and biology were not significant. A purposefully selected sample of the students were interviewed, in addition to gathering a sample of the students' daily dissection journals, as data highlighting their thoughts and feelings about their dissection experience. Further research is suggested to determine if a virtual laboratory experience can be a substitute for actual dissections, or may serve as an enhancement to an actual dissection.

  13. Effects of testosterone on sexual behavior and morphology in adult female leopard geckos, Eublepharis macularius.

    1999-10-01

    The leopard gecko, Eublepharis macularius, is a species in which testosterone (T) is the primary circulating sex hormone in adults of both sexes. There are, however, sex differences in T physiology. Whereas males have prolonged periods with high T levels, T levels cycle in accord with follicular development in females. Specifically, T concentration increases during vitellogenesis, drops after ovulation, and then remains at previtellogenic levels until eggs are laid and the next follicular cycle begins. To determine the function of T in females, we manipulated both the level and the duration of T elevation using Silastic implants in intact, adult female leopard geckos. Females had low ( approximately 1 ng/ml), medium ( approximately 100 ng/ml), or high ( approximately 200 ng/ml) T levels for either a short (8 days) or a long (35 days) duration. Behavior tests with males were conducted on days 1-5 in the short-duration group or on days 29-33 in the long-duration group. For both short- and long-duration groups, T treatment decreased attractivity in females with medium and high T levels compared to females with low T levels. In contrast, females with a medium T level were more receptive than females with a low T level in the short-duration group. Females in the long-duration group were unreceptive regardless of T level. Females treated for a long duration also displayed more aggression toward and evoked more aggression from males than short duration females. Short-duration T treatment had no masculinizing effect on female morphology, whereas medium and high T levels for a long duration induced development of hemipenes. Overall, these results suggest that T can both increase and decrease sexual behaviors in the female leopard gecko. PMID:10506536

    Influence of the administration of prolactin to female swine during puberty on the ultrastructure of pinealocytes has been examined by means of morphometric analysis. Prolactin administration for 15 consecutive days resulted in a decrease in the cytoplasmic dense bodies type MBB-2, lysosomes and multivesicular bodies. Some differences in structure of pinealocytes were also observed. Prolactin appeared to stimulate the process of transformation of cytoplasmic dense bodies. (author). 28 refs, 5 figs.

    2016-04-01

    Copulation in Ixodes scapularis involves physical contact between the male and female (on or off the host), male mounting of the female, insertion/maintenance of the male chelicerae in the female genital pore (initiates spermatophore production), and the transfer of the spermatophore by the male into the female genital pore. Bioassays determined that male mounting behavior/chelicerae insertion required direct contact with the female likely requiring non-volatile chemical cues with no evidence of a female volatile sex pheromone to attract males. Unfed virgin adult females and replete mated adult females elicited the highest rates of male chelicerae insertion with part fed virgin adult females exhibiting a much lower response. Whole body surface hexane extracts of unfed virgin adult females and males, separately analyzed by GC-MS, identified a number of novel tick surface associated compounds: fatty alcohols (1-hexadecanol and 1-heptanol), a fatty amide (erucylamid), aromatic hydrocarbons, a short chain alkene (1-heptene), and a carboxylic acid ester (5β-androstane). These compounds are discussed in terms of their potential role in female-male communication. The two most abundant fatty acid esters found were butyl palmitate and butyl stearate present in ratios that were sex specific. Only 6 n-saturated hydrocarbons were identified in I. scapularis ranging from 10 to 18 carbons. PMID:26864785

  17. Percutaneous absorption of triadimefon in the adult and young male and female rat

    International Nuclear Information System (INIS)

    The percutaneous absorption of 14C-phenoxy ring labeled triadimefon was studied in adult and young male and female Sprague-Dawley rats. Triadimefon was applied (41.1 to 46.4 micrograms/cm2) in 0.2 ml of acetone to areas comprising 3% of the body surface (7.0 to 14.5 cm2). Thirty-six animals were treated at the initiation of each study. Groups of three animals were subsequently killed at 1, 4, 8, 12, 24, 48, 72, 96, 120, 144, 168, and 192 hr after treatment. Skin from the treated area as well as blood, heart, liver, kidneys, remaining carcass, urine, and feces were analyzed for 14C by scintillation counting techniques. Based on 14C counts, triadimefon was lost more rapidly from the skin of young animals (t 1/2, 20 to 25 hr) than from the skin of adult animals (t 1/2, 29 to 53 hr). Recovery studies indicated that adult males, adult females, young males, and young females, respectively, absorbed 53, 82, 57, and 52% of the dose. The rest of the dose based on material balance was presumably lost by evaporation. Approximately 2.5 to 3.9% of the dose penetrated the skin in one hour and was available for absorption. The rate of entry triadimefon into blood was 2 to 2.5 times faster for young than that observed in adult animals. Elimination of it from blood was faster in the case of the young animals. Triadimefon was absorbed through the skins of the adult male, adult female, young male, and young female rats, respectively, at rates of 0.20, 0.50, 0.58, and 0.48 micrograms/hr/cm2 of skin

    Commercial shipments of Orius spp. (Hemiptera: Anthocoridae) commonly include water and protein, the latter typically supplied by eggs from a moth such as Ephestia kuehniella (Zeller). To determine whether modified dietary conditions might improve predation, newly eclosed adult female Orius pumilio (Champion) were fed on E. kuehniella eggs plus encapsulated water, encapsulated 5% sucrose solution only, or encapsulated water only for periods of 24, 48, or 72 h. Feeding activity was assessed by measuring the area of a crop in digital images of dissected digestive tracts. Adult females fed continuously on eggs had larger crops than did females fed on encapsulated sucrose solution. When females were prefed encapsulated water or sucrose and then fed 3 h on eggs, their crops became highly engorged and were larger than those in females fed continuously on eggs for the same periods. In behavioral choice tests, adult females prefed on encapsulated water or 5% sucrose solution spent a larger portion of time in contact with eggs, presumably feeding, whereas females prefed on eggs showed no preference between eggs or encapsulated water. After overnight shipping, females prefed on water or sucrose and held for 48 h total consumed 3.6- and 4.3-fold, respectively, more western flower thrips, Frankliniella occidentalis (Pergande), in 3 h than those prefed on eggs. Survival rates when prefed on sugar or water were comparable with prefeeding on eggs. Thus, inundative releases of Orius can be enhanced by starvation, because females initially feed much more voraciously after shipment with no apparent reduction in fitness. PMID:19449628

  1. A behavioral comparison of male and female adults with high functioning autism spectrum conditions.

    Full Text Available Autism spectrum conditions (ASC affect more males than females in the general population. However, within ASC it is unclear if there are phenotypic sex differences. Testing for similarities and differences between the sexes is important not only for clinical assessment but also has implications for theories of typical sex differences and of autism. Using cognitive and behavioral measures, we investigated similarities and differences between the sexes in age- and IQ-matched adults with ASC (high-functioning autism or Asperger syndrome. Of the 83 (45 males and 38 females participants, 62 (33 males and 29 females met Autism Diagnostic Interview-Revised (ADI-R cut-off criteria for autism in childhood and were included in all subsequent analyses. The severity of childhood core autism symptoms did not differ between the sexes. Males and females also did not differ in self-reported empathy, systemizing, anxiety, depression, and obsessive-compulsive traits/symptoms or mentalizing performance. However, adult females with ASC showed more lifetime sensory symptoms (p = 0.036, fewer current socio-communication difficulties (p = 0.001, and more self-reported autistic traits (p = 0.012 than males. In addition, females with ASC who also had developmental language delay had lower current performance IQ than those without developmental language delay (p<0.001, a pattern not seen in males. The absence of typical sex differences in empathizing-systemizing profiles within the autism spectrum confirms a prediction from the extreme male brain theory. Behavioral sex differences within ASC may also reflect different developmental mechanisms between males and females with ASC. We discuss the importance of the superficially better socio-communication ability in adult females with ASC in terms of why females with ASC may more often go under-recognized, and receive their diagnosis later, than males.

    Full Text Available Background. Brugada syndrome accounts for 4–12% of all sudden deaths worldwide and at least 20% of sudden deaths in patients with structurally normal hearts. Case Report. A 48-year-old female presented to the emergency department after two witnessed syncopal episodes. While awaiting discharge had a third collapse followed by cardiac arrest with shockable rhythm. Initial electrocardiogram showed wide QRS complex with left axis deviation, ST-segment elevation of 2 mm followed by a negative T wave with no isoelectric separation, suggestive of spontaneous intermittent Brugada type 1 pattern. Cardiac magnetic resonance imaging demonstrated neither structural heart disease nor abnormal myocardium. After placement of an implantable cardioverter defibrillator the patient was discharged. Why should an emergency physician be aware of this? Brugada syndrome is an infrequently encountered clinical entity which may have a fatal outcome. This syndrome primarily presents with syncope. It should be considered as a component of differential diagnosis in patients with family history of syncope and sudden cardiac death.

    Du, Hongling; Taylor, Hugh S

    2016-01-01

    HOX genes convey positional identity that leads to the proper partitioning and adult identity of the female reproductive track. Abnormalities in reproductive tract development can be caused by HOX gene mutations or altered HOX gene expression. Diethylstilbestrol (DES) and other endocrine disruptors cause Müllerian defects by changing HOX gene expression. HOX genes are also essential regulators of adult endometrial development. Regulated HOXA10 and HOXA11 expression is necessary for endometrial receptivity; decreased HOXA10 or HOXA11 expression leads to decreased implantation rates. Alternation of HOXA10 and HOXA11 expression has been identified as a mechanism of the decreased implantation associated with endometriosis, polycystic ovarian syndrome, leiomyoma, polyps, adenomyosis, and hydrosalpinx. Alteration of HOX gene expression causes both uterine developmental abnormalities and impaired adult endometrial development that prevent implantation and lead to female infertility. PMID:26552702

Upper lid biopsy histopathological evaluation and immunophenotyping revealed a homogenous mass of atypical CD10 and CD20-negative B-cells and tingible body macrophages yielding a "starry sky" appearance. Cytogenetic analysis detected a minor variant c-MYC translocation, but no Epstein–Barr virus RNA. Detection of multiple lesions prompted a diagnosis of stage IV disease that totally regressed following radiation and chemotherapy. Review results of the six adult orbital sBL cases support a poor prognosis and a heightened suspicion of variant CD10, CD20 and BCL6 positive sBL in adults presenting with jaw pain and rapidly progressive orbital symptoms, particularly in female, African American, and diabetic patients.Keywords: B-cells, Burkitt lymphoma, cancer, diabetes, eye, Epstein–Barr virus, orbit, tumor

    Fructose intake from added sugars correlates with the epidemic rise in metabolic syndrome and related events. Nevertheless, consumption of beverages sweetened with fructose is not regulated in gestation. Previously, we found that maternal fructose intake produces in the progeny, when fetuses, impaired leptin signaling and hepatic steatosis and then impaired insulin signaling and hypoadiponectinemia in adult male rats. Interestingly, adult females from fructose-fed mothers did not exhibit any of these disturbances. However, we think that, actually, these animals keep a programmed phenotype hidden. Fed 240-day-old female progeny from control, fructose- and glucose-fed mothers were subjected for 3weeks to a fructose supplementation period (10% wt/vol in drinking water). Fructose intake provoked elevations in insulinemia and adiponectinemia in the female progeny independently of their maternal diet. In accordance, the hepatic mRNA levels of several insulin-responsive genes were similarly affected in the progeny after fructose intake. Interestingly, adult progeny of fructose-fed mothers displayed, in response to the fructose feeding, augmented plasma triglyceride and NEFA levels and hepatic steatosis versus the other two groups. In agreement, the expression and activity for carbohydrate response element binding protein (ChREBP), a lipogenic transcription factor, were higher after the fructose period in female descendants from fructose-fed mothers than in the other groups. Furthermore, liver fructokinase expression that has been indicated as one of those responsible for the deleterious effects of fructose ingestion was preferentially augmented in that group. Maternal fructose intake does influence the adult female offspring's response to liquid fructose and so exacerbates fructose-induced dyslipidemia and hepatic steatosis. PMID:27142744

    Many studies in women and animal models suggest that estrogens affect cognitive function. Yet, the mechanisms by which estrogens may impact cognition remain unclear. The goal of the present study was to assess the effects of different estrogen receptor (ER) ligands on cognitive function in adult ovariectomized female rhesus monkeys. The monkeys were tested for 6 weeks on a battery of memory and attentional tasks administered on a touchscreen: the object, face, and spatial versions of the Dela...

    The similarities and differences in male and female caregivers' preferred strategies for coping and the perceived helpfulness of these strategies in managing caregiving stressors were examined in this study. Respondents were 170 caregivers (139 women and 31 men) who were primary caregivers for an elderly adult relative who was either cognitively impaired or physically frail. Results provide preliminary evidence that gender is related to frequency of use but not to the perceived helpfulness of specific coping strategies. PMID:9189986

This study aimed to assess the concerns of adult female patients with respect to such treatment.Patients and methods: We conducted an explorative study using Q methodology among 40 adult female patients with different educational and social backgrounds in Wenzhou, People’s Republic of China. We asked participants to rank a set of 41 statements about seeking orthodontic treatment on an 11-point scale from “agree most” to “disagree most”. The collected data were analyzed using the PQ Method 2.35 program. We extracted significant viewpoints using centroid factor extraction and varimax rotation.Results: We identified major factors based on how the patients ranked statements. Patients in group 1 worried about lack of information about orthodontic treatment, and may have suffered from dental phobia; patients in group 2 were all single women, and they were worried that the braces might lower their chances of finding a partner; patients in group 3 worried about appearance and speech with braces; and patients in group 4 worried about cost, pain, and dental hygiene. The remaining participants who had other viewpoints did not load to any of these four groups.Conclusion: The concerns of adult female individuals seeking orthodontic treatment are complex. A significant feature of this study was using Q methodology to analyze the psychological characteristics of the patients. This study identified four typical characterizations that are associated with each group, and our findings may aid orthodontists in improving doctor

    Dating violence (DV) is frequently reported by young adults in intimate relationships in the United States, but little is known about patterns of DV perpetration and victimization. In this study, we examined sexual and physical violence perpetration and victimization reported by young adults to determine how the violence patterns differ by sex and race/ethnicity. Data from non-Hispanic White, non-Hispanic Black, and Hispanic participants in Wave 3 of the National Longitudinal Study of Adolescent to Adult Health were analyzed. DV was assessed using responses to four questions focused on perpetration and four questions focused on victimization. The information on DV was taken from the most violent relationship reported by participants prior to Wave 3. Latent class analysis was first conducted separately by sex, adjusting for age, race/ethnicity, and financial stress, then by race/ethnicity, adjusting for age and financial stress. Relative model fit was established by comparing Bayesian Information Criteria (BIC), adjusted BIC, entropy, interpretability of latent classes, and certainty of latent class assignment for covariate-adjusted models. The results indicate that patterns of violence differed by sex and for females, by race/ethnicity. A three-class model was the best fit for males. For females, separate four-class models were parsimonious for White, Black, and Hispanic females. Financial stress was a significant predictor of violence classification for males and females and age predicted membership in White and Black female models. Variations in DV patterns by sex and race/ethnicity suggest the need for a more nuanced understanding of differences in DV. PMID:25846756

    Full Text Available The Paraguayan caiman (Caiman yacare is the main Caimaninae species occurring in the Brazilian Pantanal Wetland. Despite the relative availability of works focused on biology and conservation of the Paraguayan caiman, almost nothing is known about its vocal structure and behavior. We recorded aggressive calls of adult caiman females guarding nests and, afterwards, the distress calls of the new born juvenile caimans in seasonally flooded areas of the Nhecolândia (Southern Pantanal. The results of both observations and sonographic analyses diverged from studies with other crocodilian species. Aggressive vocalization of adult females of the Paraguayan caiman was longer and more complex than the same vocalization of larger Alligatoridae species. Vocalizations of the young caimans presented interspecific differences with other crocodilian offsprings. Moreover, we found statistically significant intraspecific variation in the distress call structure among different pods, even separated by few kilometers. Differences in distress call structure were tested by Canonical Discriminant Analysis (CDA. We obtained the squared Mahalanobis distances between the acoustic multivariate spaces of each pod provided by the CDA and compared with the geographic distance between the bays of origin of each pod through Mantel Test. The geographic distance by itself did not explain the differences found in the structure of the vocalization of young caimans from different pods. The adult females of Paraguayan caiman positively responded to playbacks of calls from juvenile caimans from pods of other regions, as well as to rough imitations of distress call. Since the adult caimans showed protective responses to quite heterogeneous vocalizations of distress by juveniles, we hypothesized that the variation in the distress call pattern may be associated to a low specificity in sound recognition by adult caimans.

    Full Text Available Abstract Background Lepidium meyenii, known as Maca, grows exclusively in the Peruvian Andes over 4000 m altitude. It has been used traditionally to increase fertility. Previous scientific studies have demonstrated that Maca increases spermatogenesis and epididymal sperm count. The present study was aimed to investigate the effects of Maca on several fertility parameters of female mice at reproductive age. Methods Adult female Balb/C mice were divided at random into three main groups: i Reproductive indexes group, ii Implantation sites group and iii Assessment of uterine weight in ovariectomized mice. Animals received an aqueous extract of lyophilized Yellow Maca (1 g/Kg BW or vehicle orally as treatment. In the fertility indexes study, animals received the treatment before, during and after gestation. The fertility index, gestation index, post-natal viability index, weaning viability index and sex ratio were calculated. Sexual maturation was evaluated in the female pups by the vaginal opening (VO day. In the implantation study, females were checked for implantation sites at gestation day 7 and the embryos were counted. In ovariectomized mice, the uterine weight was recorded at the end of treatment. Results Implantation sites were similar in mice treated with Maca and in controls. All reproductive indexes were similar in both groups of treatment. The number of pups per dam at birth and at postnatal day 4 was significantly higher in the group treated with Maca. VO day occurred earlier as litter size was smaller. Maca did not affect VO day. In ovariectomized mice, the treatment with Maca increased significantly the uterine weights in comparison to their respective control group. Conclusion Administration of aqueous extract of Yellow Maca to adult female mice increases the litter size. Moreover, this treatment increases the uterine weight in ovariectomized animals. Our study confirms for the first time some of the traditional uses of Maca to

    Full Text Available Abstract Background The understanding of bicarbonate kinetics and CO2 retention in the body is necessary to conduct amino acid tracer oxidation studies in both humans and laboratory animals. Significant metabolic activity is associated with eating which can affect bicarbonate steady state kinetics. A study was conducted to assess the impact of feeding regimen on the recovery of labelled bicarbonate and energy expenditure in adult female pigs (sows. Five catheterized sows (235 ± 5 kg were fed semi-synthetic diets as: a single meal 2 h into the infusion after an overnight fast, or in eight hourly meals starting 2 h before the infusion. Oxygen consumption, CO2 production and 14CO2 recovery (ie fraction not retained were determined during primed, constant intravenous infusions of NaH14CO3. Results The 14CO2 recovery (% after fasting (58.1 ± 4.8 was lower than that after single meal feeding (78.8 ± 5.9 or hourly meal feeding (81.0 ± 2.6, P = 0.03. CO2 production correlated with 14CO2 recovery during hourly feeding (r = 0.40, P = 0.01; this relationship was not significant after single meal feeding (P = 0.30, probably due to physical activity-associated CO2 production. Conclusions The correlation of CO2 retention factors with CO2 production during hourly feeding suggests that this regimen should be preferred for future amino acid kinetics studies.

    Synchronization of male and female locomotor activity plays a critical role in ensuring reproductive success, especially in semelparous species. The goal of this study was to elucidate the effects of individual chemical signals, or pheromones, on the locomotor activity in the sea lamprey (Petromyzon marinus). In their native habitat, adult preovulated females (POF) and ovulated females (OF) are exposed to sex pheromone compounds that are released from spermiated males and attract females to nests during their migration and spawning periods. In this study, locomotor activity of individual POF and OF was measured hourly in controlled laboratory conditions using an automated video-tracking system. Differences in the activity between a baseline day (no treatment exposure) and a treatment day (sex pheromone compound or control exposure) were examined for daytime and nighttime periods. Results showed that different pheromone compound treatments affected both POF and OF sea lamprey (p < 0.05) but in different ways. Spermiated male washings (SMW) and one of its main components, 7α,12α,24-trihydroxy-5α-cholan-3-one 24 sulfate (3kPZS), decreased activity of POF during the nighttime. SMW also reduced activity in POF during the daytime. In contrast, SMW increased activity of OF during the daytime, and an additional compound found in SMW, petromyzonol sulfate (PZS), decreased the activity during the nighttime. In addition, we examined factors that allowed us to infer the overall locomotor patterns. SMW increased the maximum hourly activity during the daytime, decreased the maximum hourly activity during the nighttime, and reduced the percentage of nocturnal activity in OF. Our findings suggest that adult females have evolved to respond to different male compounds in regards to their locomotor activity before and after final maturation. This is a rare example of how species-wide chemosensory stimuli can affect not only the amounts of activity but also the overall locomotor

Data were obtained from two population surveys, one with female adults and another with elderly women from Florianópolis (SC in 2009 - 2010. A descriptive analysis of the variables was carried out, the appropriate mean of responses about mammography was estimated and crude and adjusted Poisson regression was conducted to identify associated factors. Among adults, 23.1% answered all of the questions appropriately and the appropriate average responses was 7.2 (95%CI 7.1 - 7.3 in a total of 9. In the adjusted model, older age, higher education and income were associated with knowledge about mammography. For the elderly, 15.3% answered all questions appropriately and the average of appropriate responses was 6.4 (95%CI 5.2 - 6.5 and the factors associated with knowledge about mammography in the adjusted model were younger age groups, increased education and income, and identification of mammography as the main diagnostic method for breast cancer. Information about mammography can neither be transmitted in a clear way nor be easily understood; there are also demographic and socioeconomic differences concerning the knowledge about the exam.

    [Purpose] This study investigated the effects of gait time and trunk acceleration ratio in old-old adult females during stair climbing. [Subjects and Methods] Twenty-five older adult females who were able to walk independently volunteered for this study and were categorized into two age groups (older adults or old-old adults). Gait time and trunk acceleration ratio were measured using an accelerometer during stair climbing. [Results] Gait time and trunk acceleration ratio when climbing stairs were significantly higher in the old-old age group than in the older adults group. [Conclusions] These findings suggest that old-old females have decreased upper trunk control. In addition, gait time and the trunk acceleration ratio during stair climbing are useful clinical markers for predicting function and balance control ability in old-old elderly populations.

    Purpose: To develop a computed tomography (CT) organ dose estimation method designed to readily provide organ doses in a reference adult male and female for different scan ranges to investigate the degree to which existing commercial programs can reasonably match organ doses defined in these more anatomically realistic adult hybrid phantomsMethods: The x-ray fan beam in the SOMATOM Sensation 16 multidetector CT scanner was simulated within the Monte Carlo radiation transport code MCNPX2.6. The simulated CT scanner model was validated through comparison with experimentally measured lateral free-in-air dose profiles and computed tomography dose index (CTDI) values. The reference adult male and female hybrid phantoms were coupled with the established CT scanner model following arm removal to simulate clinical head and other body region scans. A set of organ dose matrices were calculated for a series of consecutive axial scans ranging from the top of the head to the bottom of the phantoms with a beam thickness of 10 mm and the tube potentials of 80, 100, and 120 kVp. The organ doses for head, chest, and abdomen/pelvis examinations were calculated based on the organ dose matrices and compared to those obtained from two commercial programs, CT-EXPO and CTDOSIMETRY. Organ dose calculations were repeated for an adult stylized phantom by using the same simulation method used for the adult hybrid phantom. Results: Comparisons of both lateral free-in-air dose profiles and CTDI values through experimental measurement with the Monte Carlo simulations showed good agreement to within 9%. Organ doses for head, chest, and abdomen/pelvis scans reported in the commercial programs exceeded those from the Monte Carlo calculations in both the hybrid and stylized phantoms in this study, sometimes by orders of magnitude. Conclusions: The organ dose estimation method and dose matrices established in this study readily provides organ doses for a reference adult male and female for different

    Full Text Available Abstract Background With rapid economic growth and globalization, lifestyle in China has been changing dramatically. This study aimed to describe the male and female adult Chinese population health status. Methods The Chinese Third National Health Services Survey was conducted in 2003 to collect information about health status and quality of life from randomly selected residents. Of the 193,689 respondents to the survey (response rate 77.8%, 139,831 (69,748 male and 70,083 female respondents who were 18 years of age or older were analyzed. Results Among the respondents, fewer males than females rated their overall wellbeing as being poor or very poor (4.8% versus 6.2%, reported illness in the last 2 weeks (14.1% versus 17.4%, presence of physician diagnosed chronic disease (15.0% versus 17.7% and at least one functional problem in seven items of the quality of life (26.9% versus 32.8%. More males than females were currently smoking (52.4% versus 3.4% and drank alcohol more than three times per week (16.5% versus 1.1%. Physically inactive rate was similar between males and females (85.8% versus 87.0%. Fewer rural respondents reported chronic disease than urban respondents (13.0% versus 19.9% for males and 15.5% versus 22.8% for females. In all seven items of the quality of life measured, rural respondents reported less problems than urban respondents (26.2% versus 28.7% for males and 32.0% versus 34.7% for females. Conclusion Males had better health status than females in terms of self-perceived wellbeing, presence of illness, chronic disease, and quality of life. However, smoking and frequent alcohol drinking was more prevalent among males than that among females. In contrast with the social-economic gradient in health commonly found in the literature, the wealthier urban population in China was not found to be healthier than the rural population in terms of physician diagnosed chronic disease.

    Interactions between animals and their environment are fundamental to ecological research. Field studies of coyote (Canis latrans) reproductive performance suggest mean litter size changes in response to prey abundance. However, this relationship has been assessed primarily by using carcasses collected from trappers. The objective of this study was to assess whether nutritional manipulation prior to mating affected reproduction in adult female coyotes. We examined the effects of caloric restriction during the 7 months prior to estrus on the reproductive rates of 11 captive female coyotes and the subsequent initial survival of pups through two reproductive cycles. This was a 2-year study with a cross-over design so each female was monitored for reproductive performance on each of the two diet treatments. We assessed the number of implantation scars, number of pups born, sex ratios of pups, average pup weight at birth and 2- and 6-weeks of age, and the survival rates between implantation and 2-weeks of age for two diet treatments. We found the mean number of implantation sites and pups whelped during a reproductive cycle was influenced by food-intake prior to conception. Additionally, we found evidence suggesting the effects of nutritional stress may persist for additional breeding cycles. We also provided evidence suggesting well-fed females tended to have more male pups. Understanding how environmental factors influence reproductive output may improve model predictions of coyote population dynamics. PMID:26763531

    The evidence regarding older parental age and incidence of mood disorder symptoms in offspring is limited, and that which exists is mixed. We sought to clarify these relationships by using data from the Western Australian Pregnancy Cohort (Raine) Study. The Raine Study provided comprehensive data from 2,900 pregnancies, resulting in 2,868 live born children. A total of 1,220 participants completed the short form of the Depression Anxiety Stress Scale (DASS-21) at the 20-year cohort follow-up. We used negative binomial regression analyses with log link and with adjustment for known perinatal risk factors to examine the extent to which maternal and paternal age at childbirth predicted continuous DASS-21 index scores. In the final multivariate models, a maternal age of 30-34 years was associated with significant increases in stress DASS-21 scores in female offspring relative to female offspring of 25- to 29-year-old mothers. A maternal age of 35 years and over was associated with increased scores on all DASS-21 scales in female offspring. Our results indicate that older maternal age is associated with depression, anxiety, and stress symptoms in young adult females. Further research into the mechanisms underpinning this relationship is needed. PMID:26569038

    Full Text Available The purpose of this study was to examine the effects of equine assisted therapy on selected gait parameters in a person with Down syndrome. One female participant with Down syndrome completed two therapeutic horseback riding programs, each consisting of six riding sessions. Specific gait characteristics were analyzed with a trend analysis of the data by examining the means of the different variables. The trend analysis revealed a difference in stride length as well as hip and knee angle. These results indicate that over the course of the two therapeutic horseback riding programs, changes in gait occurred. Therefore, therapeutic horseback riding may have the potential to benefit gait characteristics and stability in young adult females with Down syndrome; however, further research is warranted.

    Assessment of population size and changes therein is important to sea turtle management and population or life history research. Investigators might be interested in testing hypotheses about the effect of current population size or density (number of animals per unit resource) on future population processes. Decision makers might want to determine a level of allowable take of individual turtles of specified life stage. Nevertheless, monitoring most stages of sea turtle life histories is difficult, because obtaining access to individuals is difficult. Although in-water assessments are becoming more common, nesting females and their hatchlings remain the most accessible life stages. In some cases adult females of a given nesting population are sufficiently philopatric that the population itself can be well defined. If a well designed tagging study is conducted on this population, survival, breeding probability, and the size of the nesting population in a given year can be estimated. However, with published statistical methodology the size of the entire breeding population (including those females skipping nesting in that year) cannot be estimated without assuming that each adult female in this population has the same probability of nesting in a given year (even those that had just nested in the previous year). We present a method for estimating the total size of a breeding population (including nesters those skipping nesting) from a tagging study limited to the nesting population, allowing for the probability of nesting in a given year to depend on an individual's nesting status in the previous year (i.e., a Markov process). From this we further develop estimators for rate of growth from year to year in both nesting population and total breeding population, and the proportion of the breeding population that is breeding in a given year. We also discuss assumptions and apply these methods to a breeding population of hawksbill sea turtles (Eretmochelys imbricata) from

    While resilience research in the context of intimate partner violence (IPV) is increasing, there remains little known about women's lived experience of resilience. Using a phenomenological approach, this study examined the experience of resilience for adult female survivors of IPV. Sixteen women who were currently experiencing or had previously experienced abuse by an intimate partner participated in semi-structured interviews. Resilience was experienced as multiple cognitive, emotional, and behavioral shifts across three theme areas: toward resistance, in the experience of control, and toward positivity. The results of this study suggest a number of applications for clinical practice and intervention. PMID:26567293

    Many studies in women and animal models suggest that estrogens affect cognitive function. Yet, the mechanisms by which estrogens may impact cognition remain unclear. The goal of the present study was to assess the effects of different estrogen receptor (ER) ligands on cognitive function in adult ovariectomized female rhesus monkeys. The monkeys were tested for 6 weeks on a battery of memory and attentional tasks administered on a touchscreen: the object, face, and spatial versions of the Delayed Recognition Span Test (DRST) and a Visual Search task. Following a 2-week baseline period with oil vehicle treatment, monkeys were randomly assigned to one of 3 treatment groups: estradiol benzoate (EB), selective ERbeta agonist (diarylpropionitrile DPN) or selective ER modulator tamoxifen (TAM). In each treatment group, monkeys received oil vehicle for 2 weeks and the drug for 2 weeks, in a cross-over design. After a 4-week washout, a subset of monkeys was re-tested on the battery when treated with a selective ERalpha agonist (propyl-pyrazole-triol, PPT) or oil vehicle. Overall, drug treatments had no or negligible effects on cognitive performance. These results support the contention that exogenous estrogens and selective estrogen receptor modulators (SERMS) do not significantly affect cognition in young adult female macaques. Additional studies are needed to determine whether the cognitive effects of estrogens in monkeys of more advanced age are mediated by ERbeta, ERalpha or complex interactions between the two receptors.

    The aim of this work was to examine locomotor stability and adaptation across the adult female lifespan during perturbed walking on the treadmill. 11 young, 11 middle and 14 older-aged female adults (mean and SD: 25.5(2.1), 50.6(6.4) and 69.0(4.7) years old respectively) walked on a treadmill. We applied a sustained perturbation to the swing phase of the right leg for 18 consecutive gait cycles, followed by a step with the resistance unexpectedly removed, via an ankle strap connected to a break-and-release system. The margin of stability (MoS) at foot touchdown was calculated as the difference between the anterior boundary of the base of support (BoS) and extrapolated center of mass. Older participants showed lower MoS adaptation magnitude in the early adaptation phase (steps 1-3) compared to the young and middle-aged groups. However, in the late adaptation phase (steps 16-18) there were no significant differences in adaptation magnitude between the three age groups. After removing the resistance, all three age groups showed similar aftereffects (i.e. increased BoS). The current results suggest that in old age, the ability to recalibrate locomotion to control stability is preserved, but the rate of adaptive improvement in locomotor stability is diminished.

    Full Text Available Selective serotonin reuptake inhibitor medications are one of the most common treatments for mood disorders. In humans, these medications are taken orally, usually once per day. Unfortunately, administration of antidepressant medications in rodent models is often through injection, oral gavage, or minipump implant, all relatively stressful procedures. The aim of the present study was to investigate how administration of the commonly used SSRI, fluoxetine, via a wafer cookie, compares to fluoxetine administration using an osmotic minipump, with regards to serum drug levels and hippocampal plasticity. For this experiment, adult female Sprague-Dawley rats were divided over the two administration methods: (1 cookie and (2 osmotic minipump and three fluoxetine treatment doses: 0, 5, or 10 mg/kg/day. Results show that a fluoxetine dose of 5 mg/kg/day, but not 10 mg/kg/day, results in comparable serum levels of fluoxetine and its active metabolite norfluoxetine between the two administration methods. Furthermore, minipump administration of fluoxetine resulted in higher levels of cell proliferation in the granule cell layer (GCL at a 5 mg dose compared to a 10 mg dose. Synaptophysin expression in the GCL, but not CA3, was significantly lower after fluoxetine treatment, regardless of administration method. These data suggest that the administration method and dose of fluoxetine can differentially affect hippocampal plasticity in the adult female rat.

  4. Bone mineral density and bone scintigraphy in adult Saudi female patients with Osteomalacia

    International Nuclear Information System (INIS)

    This prospective study was conducted to demonstrate the role of bone mineral density (BMD) and bone scan in the management of adult Saudi female patients with established diagnosis of osteomalacia. Bone scan using Tc99m methylene diphosphate (MDP) and BMD of the lumbar spine and femoral neck using dual x-ray absorptiometry (DXA) were performed at the time of diagnosis 6 months and one year after therapy in 96 Saudi female patients attending the metabolic bone disease clinic at King Khalid University Hospital, King Saud University, Riyadh, Kingdom of Saudi Arabia, between January 1997 through to June 1999, aged between 20 and 73 years (mean 42 years). Alkaline phosphates, calcium and inorganic phosphorus were measured for all patients before and after treatment. 25 Hydroxy vitamin D was only measured with the first BMD measurements. A bone profile showed typical biochemical abnormalities of osteomalacia.The bone scan showed features of superscan in all patients and pseudofractures in 43 patients. BMD measures were compared with that of normal Saudi subjects matched for age and sex. The BMD was low at diagnosis and showed significant improvement after therapy. The improvement of bone density in response to therapy was more evident in lumbar spine than in femoral neck bone.Our results showed that BMD in adult Saudi female patients with osteomalacia was markedly affected probably due to specific constitutional and environmental factors ( inadeqate exercise, lack of sun exposure and lack of intake of milk and dairy products). In addition, lumbar BMD and serum calcium appeared to be better markers to monitor therapy.Bone scan helped in demonstrating disease activity, the presence of pseudofractures. (author)

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the dentofacial relationship of the Korean adult females who had excellent profile using roentgenocephalometry. The subjects were 35 females from 18 to 24 years of age selected among the professional models, beauty contest winners and performing stars. And, as the control group, 37 females from 18 to 23 years of age with normal occlusion and acceptable profile were selected. In both groups, each variable was measured and evaluated statistically introducing 24 reference points, 22 reference lines and 17 reference angles respectively. Conclusion from this study were as follows: 1. There was no significant difference between the two groups. But SNA and convexity angle which had indicated the maxillary protrusion were lesser in the professional models, beauty contest winners and performing stars than in the control group. 2. In the professional models, beauty contest winners and performing stars, the maxillary and mandibular incisors were more upright than in the control group. 3. The protrusion of the upper and lower lip was lesser in the professional models, beauty contest winners and performing stars than in the control group. 4. Professional models, beauty contest winners and performing stars revealed more straight profile than the control group and were similar to that of the Caucasian. 5. Generally, it was the tendency that the straight profile was accepted as esthetics.

    Full Text Available The adaptive immune response of the genital tract is under the control of sexual steroids; however, the influence of sex hormones on innate immune mechanisms of the genital mucosa are only beginning to be understood. We found that long-term estrogen treatment increases the risk for inflammatory pelvic diseases in adult non-castrated female rats. Female rats (110 g to 130 g received estrogen (10 rats; 17-beta estradiol, 50 mg pellet; 10 rats: subcutaneous weekly injection of estradiol valerate 0.166 mg/kg. Ten rats received a pellet of 17-beta estradiol and were treated with amoxicillin, 50 mg/kg after the 90th day of exposure to estrogen. Three control groups of ten rats were also used. The estrogen-treated rats developed an inflammatory pelvic disease, with abscess formation after the third month of hormonal treatment. All the surviving animals were killed after six months of hormonal exposure. Among 15 survivors of the two groups that received estrogen 13 animals presented tuboovarian abscesses. Among eight survivors of the group treated with amoxicillin, six had tuboovarian abscesses. None of the 30 control rats presented macro or microscopic signs of inflammatory disease in the uterus, tubes or ovaries. We conclude that estrogen impairs the defense mechanisms of the genital tract of non-castrated female rats, enhancing bacterial growth in the vagina and ascending infection to the uterus, tubes and ovaries.

    Despite the efforts of many natural resource professionals, wild pig (Sus scrofa) populations are expanding in many areas of the world. Although many creative techniques for controlling pig populations are being explored, trapping has been and still is themost commonly usedmethod of population control formany public and private land managers. We conducted an observational study to examine the efficiency of 2 frequently used trap styles: a small, portable box-style trap and a larger, semi-permanent, corral-style trap.We used game cameras to examine patterns of trap entry by wild pigs around each style of trap, and we conducted a trapping session to compare trapping success between trap styles. Adult female and juvenile wild pigs entered both styles of trap more readily than did adult males, and adult males seemed particularly averse to entering box traps. Less than 10% of adult male visits to box traps resulted in entries, easily the least percentage of any class at any style of trap. Adult females entered corral traps approximately 2.2 times more often per visit than box traps and re-entered corral traps >2 times more frequently. Juveniles entered and reentered both box and corral traps at similar rates. Overall (all-class) entry-per-visit rates at corral traps (0.71) were nearly double that of box traps (0.37). Subsequent trapping data supported these preliminary entry data; the capture rate for corral traps was >4 times that of box traps. Our data suggest that corral traps are temporally and economically superior to box traps with respect to efficiency; that is, corral traps effectively trap more pigs per trap night at a lower cost per pig than do box traps. ?? 2011 The Wildlife Society.

    Burkitt's lymphoma is an uncommon and aggressive type of Non-Hodgkin's lymphoma and is one of the fastest growing cancer tumour in humans; growth fraction close to 100%. We report a case of a young adult female presented with acute pain abdomen with ileo-caecal mass. On clinical presentation, initial diagnosis was acute appendicitis with lump formation. Ultrasound reported as diffuse inflammatory changes and later CECT was done which reported as Gastro-Intestinal Stromal Tumour (GIST). On laparotomy, a huge hard mass was found on ileo-caecal region and right hemicolectomy was done. Diagnosis was confirmed as Non-Hodgkins Burkitt's Lymphoma by HPE and immunohistochemistry testing. So, careful workup is the key to initiate early treatment. This patient had complete remission after the right hemicolectomy followed by multiagent chemotherapy. PMID:27190885

    There is limited large-scale research into the lived experiences of female adults who have an autism spectrum disorder with no co-occurring intellectual disability. Drawing on the findings of an Australia-wide survey, this report presents self-report data fromn = 82 women with high-functioning autism spectrum disorder in the areas of health, education, employment, social and community activities. Where relevant, comparisons are provided with the male subset of the same study population; however, in the majority of analyses, no discernible gender differences emerged. The findings highlight the diverse and complex challenges faced by women with high-functioning autism spectrum disorder, including high levels of mental health disorder, unmet support needs in education settings and the workplace, and social exclusion and isolation.

    Full Text Available A percentage of ureteropelvic junction obstruction cases are clinically silent in childhood and manifest symptoms in adults. Herein we present a 25-year-old female with several years of intermittent flank pain and abdominal symptoms with prior inconclusive diagnostic workup including abdominal imaging without hydronephrosis. Ultimately, a CT scan performed during an acute pain crisis clearly identified right-sided hydronephrosis. The keys to diagnosis are awareness of this entity, a detailed history, and obtaining imaging studies during a crisis. The patient subsequently underwent a right robotic-assisted laparoscopic pyeloplasty with preservation of a lower pole crossing vessel. We highlight noteworthy features of the clinical presentation and surgical repair.

    Early adverse events have been shown to increase the incidence of interstitial cystitis/painful bladder syndrome in adulthood. Despite high clinical relevance and reports of stress-related symptom exacerbation, animal models investigating the contribution of early life stress to female urological pain are lacking. We examined the impact of neonatal maternal separation (NMS) on bladder sensitivity and visceral neuroimmune status both prior-to, and following, water avoidance stress (WAS) in adult female mice. The visceromotor response to urinary bladder distension was increased at baseline and 8d post-WAS in NMS mice, while colorectal sensitivity was transiently increased 1d post-WAS only in naïve mice. Bladder micturition rate and output, but not fecal output, were also significantly increased following WAS in NMS mice. Changes in gene expression involved in regulating the stress response system were observed at baseline and following WAS in NMS mice, and WAS reduced serum corticosterone levels. Cytokine and growth factor mRNA levels in the bladder, and to a lesser extent in the colon, were significantly impacted by NMS and WAS. Peripheral mRNA levels of stress-responsive receptors were differentially influenced by early life and adult stress in bladder, but not colon, of naïve and NMS mice. Histological evidence of mast cell degranulation was increased in NMS bladder, while protein levels of protease activated receptor 2 (PAR2) and transient receptor potential ankyrin 1 (TRPA1) were increased by WAS. Together, this study provides new insight into mechanisms contributing to stress associated symptom onset or exacerbation in patients exposed to early life stress. PMID:26940840

    Full Text Available Problem statement: Over the past two decades there has been a striking increase in the number of people with metabolic syndrome in developing countries. The current study was thus undertaken to map the prevalence of Metabolic Syndrome (MS and to assess the cardio-metabolic risk factors among young adult females (n = 1303 aged 18-26y from four girls hostel of the Maharaja Sayajirao University of Baroda. Approach: The anthropometric analysis showed a high prevalence of overweight/obesity (20.8%, abdominal obesity (12.7% among the subjects. The clinical profile revealed that 12.1% were hypertensives. The prevalence of dyslipidemia revealed that no one had hypercholesterolemia and 4.1% had hypertriglyceridemia, 12.1% had elevated LDL-C and 40.3% had low levels of HDL-C. The prevalence of metabolic syndrome was 2.4 and 4.1% according to the International Diabetes Federation (IDF and World Health Organization (WHO criteria respectively. Lipid profile in relation to metabolic syndrome showed that VLDL-C and Triglyceride (TG values were non-significantly higher among the young adult females and HDL-C values were significantly (pResults: The three common and predominant risk factors (>80% identified were lower intake of fruits (81.5%, vegetables (96% and physical inactivity (88.7%. The other risk factors which were present between 30-50% were hypertension, lower HDL-C, Body Mass Index (BMI and Waist Circumference (WC. Among the non-modifiable factor heredity component was present in 34% of the subjects. Conclusion: The study highlights that lifestyle factors had equivalent risk for overweight and metabolic syndrome. Multiple risk factor scenario calls for lifestyle management to avert later consequences.

    Current sexual selection theory proposes several potential mechanisms driving the evolution of female mating preferences, few of which involve social interactions. Although vertebrate examples of socially influenced mating preferences do exist, the invertebrate examples are virtually nonexistent. Here I demonstrate that the mating preferences of female wolf spiders can be acquired through exposure as subadults to unrelated, sexually active adult males.

    Full Text Available Abstract Background Establishing personal identity is one of the main concerns in forensic investigations. Estimation of stature forms a basic domain of the investigation process in unknown and co-mingled human remains in forensic anthropology case work. The objective of the present study was to set up standards for estimation of stature from the foot and its segments in a sub-adult female population. Methods The sample for the study constituted 149 young females from the Northern part of India. The participants were aged between 13 and 18 years. Besides stature, seven anthropometric measurements that included length of the foot from each toe (T1, T2, T3, T4, and T5 respectively, foot breadth at ball (BBAL and foot breadth at heel (BHEL were measured on both feet in each participant using standard methods and techniques. Results The results indicated that statistically significant differences (p p-value Conclusions The present study concluded that foot measurements have a strong relationship with stature in the sub-adult female population of North India. Hence, the stature of an individual can be successfully estimated from the foot and its segments using different regression models derived in the study. The regression models derived in the study may be applied successfully for the estimation of stature in sub-adult females, whenever foot remains are brought for forensic examination. Stepwise multiple regression models tend to estimate stature more accurately than linear regression models in female sub-adults.

  17. Dietary Antioxidants Effectiveness on Carbon Tetrachloride-Induced Hepatotoxicity in Adult Female Albino Rats

    International Nuclear Information System (INIS)

    Hepatic toxicity through carbon tetrachloride (CCI4) induced lipid peroxidation was extensively used in experimental models to understand the cellular mechanisms behind oxidative damage and to evaluate the therapeutic potential of drugs and dietary antioxidants. The ameliorative effect of Aloe vera juice and carrot supplementation on hepato carcinogenesis induced by carbon tetrachloride in adult female albino rats was investigated. The carcinogenic process was determined by measuring gamma-glutamyl transpeptidase (GGT), ornithine carbamyl transferase (OCT), thiobarbituric acid reactive substances (TBARs), representing levels of lipid peroxides, and carcinoembryonic antigen (CEA) in the sera of female albino rats. Carbon tetrachloride significantly elevated the serum GGT, OCT activities and the level of TBARs. Administration of Aloe vera leaf juice filtrate after CCl4 treatment resulted in a non-significant modification in GGT, OCT activities and significantly improved the level of TBARs in comparison with control. Supplementation of carrot to CCI4 treated animals led to a great amelioration in OCT activity and TBARs level, whereas GGT activity was ameliorated but statistically changed compared to control. There was a non-significant alteration in the level of CEA in all treated groups compared to normal control one

    International Nuclear Information System (INIS)

    To measure serum leptin levels and compare them in lean and obese subjects and to identify correlation between serum leptin levels, heart rate and hypertension in lean and obese subjects among adult females. Seventy female subjects with different body mass indices were selected from OPD of Jinnah Medical and Dental College Hospital (OPD), Karachi. Heart rate was counted manually; blood pressure was measured by mercury sphygmomanometer while serum leptin was measured using enzyme-linked immunoassay. The outcomes hypertension and heart rate were correlated to risk factor leptin. Mean heart rate, systolic and diastolic blood pressure and serum leptin levels of obese people were 90+-1, 142+-2, 89+-1 and 24.13+-1.7 respectively, which were significantly higher as compared to lean subjects (p<0.05). All the parameters correlated positively and significantly with increasing BMI. There was a relationship of tachycardia and hypertension with high serum leptin levels in obesity. Serum leptin levels increase with the level of obesity. Hyper-leptinemia is associated with tachycardia and increases in both systolic and diastolic blood pressure in obesity via complex mechanisms.

    There is a controversy regarding the effects of the analogues of the gonadotrophin-releasing hormone (GnRH) in radiotherapy. This has led us to study the possible radio-protection of the ovarian function of a GnRH agonist analogue (GnRHa), triptorelin, in adult, female rats (Rattus norvegicus sp.). The effects of the X-irradiation on the oocytes of ovarian primordial follicles, with and without GnRHa treatment, were compared, directly in the female rats (F{sub 0}) with reproductive parameters, and in the somatic cells of the resulting foetuses (F{sub 1}) with cytogenetical parameters. In order to do this, the ovaries and uteri from 82 females were extracted for the reproductive analysis and 236 foetuses were obtained for cytogenetical analysis. The cytogenetical study was based on the data from 22,151 metaphases analysed. The cytogenetical parameters analysed to assess the existence of chromosomal instability were the number of aberrant metaphases (2234) and the number (2854) and type of structural chromosomal aberrations, including gaps and breaks. Concerning the reproductive analysis of the ovaries and the uteri, the parameters analysed were the number of corpora lutea, implantations, implantation losses and foetuses. Triptorelin confers radio-protection of the ovaries in front of chromosomal instability, which is different, with respect to the single and fractioned dose. The cytogenetical analysis shows a general decrease in most of the parameters of the triptorelin-treated groups, with respect to their controls, and some of these differences were considered to be statistically significant. The reproductive analysis indicates that there is also radio-protection by the agonist, although minor to the cytogenetical one. Only some of the analysed parameters show a statistically significant decrease in the triptorelin-treated groups.

    Satellite telemetry and stable isotope analysis were used to confirm that oceanic areas (where water depths are >200 m) are alternative feeding habitats for adult female green sea turtles (Chelonia mydas), which have been thought to be obligate herbivores in neritic areas (where depths are 20 m, implying that they not only rested, but also foraged on macroplankton that exhibit diel vertical migration. Comparisons of stable carbon and nitrogen isotope ratios between 89 females and the prey items in a three-source mixing model estimated that 69% of the females nesting on Ogasawara Islands mainly used neritic habitats and 31% mainly used oceanic habitats. Out of four females tracked by satellite, two females were inferred from isotope ratios to be neritic herbivores and the two others oceanic planktivores. Although post-nesting movements for four females were not completely consistent with the inferences from isotope ratios, possibly due to short tracking periods (28-42 days), their diving behaviors were consistent with the inferences. There were no relationships between body size and the two isotope ratios, indicating a lack of size-related differences in feeding habitat use by adult female green turtles, which was in contrast with loggerhead sea turtles (Caretta caretta). These results and previous findings suggest that ontogenetic habitat shifts by sea turtles are facultative, and consequently, their life histories are polymorphic. PMID:16683139

    Attention deifcit hyperactivity disorder (ADHD) is a pervasive psychiatric disorder that affects both chil-dren and adults. Adult male and female patients with ADHD are differentially affected, but few studies have explored the differences. The purpose of this study was to quantify differences between adult male and female patients with ADHD based on neuroimaging and connectivity analysis. Resting-state functional magnetic resonance imaging scans were obtained and preprocessed in 82 patients. Group-wise differences between male and female patients were quantiifed using degree centrality for different brain regions. The medial-, middle-, and inferior-frontal gyrus, superior parietal lobule, precuneus, supramarginal gyrus, superior- and middle-temporal gyrus, middle occipital gyrus, and cuneus were identiifed as regions with signiifcant group-wise differences. The identiifed regions were correlated with clinical scores relfecting de-pression and anxiety and signiifcant correlations were found. Adult ADHD patients exhibit different levels of depression and anxiety depending on sex, and our study provides insight into how changes in brain cir-cuitry might differentially impact male and female ADHD patients.

    Full Text Available Decline in the ovarian hormones with menopause may influence somatosensory, cognitive, and affective processing. The present study investigated whether hormonal depletion alters the nociceptive, depressive-like and learning behaviors in experimental rats after ovariectomy (OVX, a common method to deplete animals of their gonadal hormones. OVX rats developed thermal hyperalgesia in proximal and distal tail that was established 2 weeks after OVX and lasted the 7 weeks of the experiment. A robust mechanical allodynia was also occurred at 5 weeks after OVX. In the 5th week after OVX, dilute formalin (5%-induced nociceptive responses (such as elevating and licking or biting during the second phase were significantly increased as compared to intact and sham-OVX females. However, chronic constriction injury (CCI of the sciatic nerve-induced mechanical allodynia did not differ as hormonal status (e.g. OVX and ovarian intact. Using formalin-induced conditioned place avoidance (F-CPA, which is believed to reflect the pain-related negative emotion, we further found that OVX significantly attenuated F-CPA scores but did not alter electric foot-shock-induced CPA (S-CPA. In the open field and forced swimming test, there was an increase in depressive-like behaviors in OVX rats. There was no detectable impairment of spatial performance by Morris water maze task in OVX rats up to 5 weeks after surgery. Estrogen replacement retrieved OVX-induced nociceptive hypersensitivity and depressive-like behaviors. This is the first study to investigate the impacts of ovarian removal on nociceptive perception, negative emotion, depressive-like behaviors and spatial learning in adult female rats in a uniform and standard way.

  12. Diffuse hair loss in an adult female: Approach to diagnosis and management

    2009-01-01

    Full Text Available Telogen effluvium (TE is the most common cause of diffuse hair loss in adult females. TE, along with female pattern hair loss (FPHL and chronic telogen effluvium (CTE, accounts for the majority of diffuse alopecia cases. Abrupt, rapid, generalized shedding of normal club hairs, 2-3 months after a triggering event like parturition, high fever, major surgery, etc. indicates TE, while gradual diffuse hair loss with thinning of central scalp/widening of central parting line/frontotemporal recession indicates FPHL. Excessive, alarming diffuse shedding coming from a normal looking head with plenty of hairs and without an obvious cause is the hallmark of CTE, which is a distinct entity different from TE and FPHL. Apart from complete blood count and routine urine examination, levels of serum ferritin and T3, T4, and TSH should be checked in all cases of diffuse hair loss without a discernable cause, as iron deficiency and thyroid hormone disorders are the two common conditions often associated with diffuse hair loss, and most of the time, there are no apparent clinical features to suggest them. CTE is often confused with FPHL and can be reliably differentiated from it through biopsy which shows a normal histology in CTE and miniaturization with significant reduction of terminal to vellus hair ratio (T:V < 4:1 in FPHL. Repeated assurance, support, and explanation that the condition represents excessive shedding and not the actual loss of hairs, and it does not lead to baldness, are the guiding principles toward management of TE as well as CTE. TE is self limited and resolves in 3-6 months if the trigger is removed or treated, while the prognosis of CTE is less certain and may take 3-10 years for spontaneous resolution. Topical minoxidil 2% with or without antiandrogens, finestride, hair prosthesis, hair cosmetics, and hair surgery are the therapeutically available options for FPHL management.

  13. Pheromones from males of different familiarity exert divergent effects on adult neurogenesis in the female accessory olfactory bulb.

    Pheromones from urine of unfamiliar conspecific male animals can reinitiate a female's estrus cycle to cause pregnancy block through the vomeronasal organ (VNO)-accessory olfactory bulb (AOB)-hypothalamic pathway. This phenomenon is called the Bruce effect. Pheromones from the mate of the female, however, do not trigger re-entrance of the estrus cycle because an olfactory memory toward its mate is formed. The activity of the VNO-AOB-hypothalamic pathway is negatively modulated by GABAergic granule cells in the AOB. Since these cells are constantly replenished by neural stem cells in the subventricular zone (SVZ) of the lateral ventricle throughout adulthood and adult neurogenesis is required for mate recognition and fertility, we tested the hypothesis that pheromones from familiar and unfamiliar males may have different effects on adult AOB neurogenesis in female mice. When female mice were exposed to bedding used by a male or lived with one, cell proliferation and neuroblast production in the SVZ were increased. Furthermore, survival of newly generated cells in the AOB was enhanced. This survival effect was transient and mediated by norepinephrine. Interestingly, male bedding-induced newborn cell survival in the AOB but not cell proliferation in the SVZ was attenuated when females were subjected to bedding from an unfamiliar male. Our results indicate that male pheromones from familiar and unfamiliar males exert different effects on neurogenesis in the adult female AOB. Given that adult neurogenesis is required for reproductive behaviors, these divergent pheromonal effects may provide a mechanism for the Bruce effect. © 2013 Wiley Periodicals, Inc.

    The influence of adult body size on the pre-gravid state and fecundity was studied in Anopheles gambiae Giles females hand-caught inside houses and virgin females collected as pupae in Tanzania. Blood-fed mosquitoes were kept for 2-3 days before dissection and examination for insemination and ovarian condition. Those females which did not develop eggs were classified as pre-gravid. The number of mature eggs in those mosquitoes which became gravid was counted. Virgin females were fed and kept for egg maturation in the laboratory. Wing-length of females was measured as an index of mosquito size. The overall pre-gravid rate in the resting An.gambiae population was found to be 21% and, of these, 66% had been inseminated. In the virgin females the pre-gravid rate was 92.6%. The mean wing-length of wild females which became gravid was significantly larger than those which remained pre-gravid. There was a positive correlation between fecundity and wing-length. Smaller females tended to require two or three bloodmeals to facilitate completion of the first gonotrophic cycle. The critical size permitting oviposition from the first blood-meal was a wing-length of 3 mm. PMID:8268486

    Full Text Available Abstract Background Most filarial nematodes contain Wolbachia symbionts. The purpose of this study was to examine the effects of doxycycline on gene expression in Wolbachia and adult female Brugia malayi. Methods Brugia malayi infected gerbils were treated with doxycycline for 6-weeks. This treatment largely cleared Wolbachia and arrested worm reproduction. RNA recovered from treated and control female worms was labeled by random priming and hybridized to the Version 2- filarial microarray to obtain expression profiles. Results and discussion Results showed significant changes in expression for 200 Wolbachia (29% of Wolbachia genes with expression signals in untreated worms and 546 B. malayi array elements after treatment. These elements correspond to known genes and also to novel genes with unknown biological functions. Most differentially expressed Wolbachia genes were down-regulated after treatment (98.5%. In contrast, doxycycline had a mixed effect on B. malayi gene expression with many more genes being significantly up-regulated after treatment (85% of differentially expressed genes. Genes and processes involved in reproduction (gender-regulated genes, collagen, amino acid metabolism, ribosomal processes, and cytoskeleton were down-regulated after doxycycline while up-regulated genes and pathways suggest adaptations for survival in response to stress (energy metabolism, electron transport, anti-oxidants, nutrient transport, bacterial signaling pathways, and immune evasion. Conclusions Doxycycline reduced Wolbachia and significantly decreased bacterial gene expression. Wolbachia ribosomes are believed to be the primary biological target for doxycycline in filarial worms. B. malayi genes essential for reproduction, growth and development were also down-regulated; these changes are consistent with doxycycline effects on embryo development and reproduction. On the other hand, many B. malayi genes involved in energy production, electron

    Purpose: To report a case of a macular hole in a female adult with bilateral Coats disease.Methods:The fundus photograph, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed in two eyes, and observed theirs characters.Results:Fundus photograph showed massive yellowish-white exudation in the temporal midperiphery of both eyes, but the degree was slighter in the right eye. There was 1/3 DD macular hole in left eye. FFA revealed general dilatation of capillaries, multiple aneurysms, and tortuous and closure of vessels in superotemporal midperiphery in both eyes, but the degree was slighter in the right eye. There was a one-third DD round transmitted fluorescence according the macula hole. ICGA revealed that hyperfluorescence of aneurysms in superotemporal midperiphery, the images of aneurysms were more clearly than in FFA. There was a 2/3 DD hypoflurescence of macula in the late phase of angiography.Conclusions: FFA and ICGA have respective advantage in revealing vascular abnormalities of Coats disease. Maybe there was some relationship between the abnormalities of retinal vascular and hypoperfusion of choroidial vascular in macula in this case.

  17. Genetic and environmental influences on female sexual orientation, childhood gender typicality and adult gender identity.

    Full Text Available BACKGROUND: Human sexual orientation is influenced by genetic and non-shared environmental factors as are two important psychological correlates--childhood gender typicality (CGT and adult gender identity (AGI. However, researchers have been unable to resolve the genetic and non-genetic components that contribute to the covariation between these traits, particularly in women. METHODOLOGY/PRINCIPAL FINDINGS: Here we performed a multivariate genetic analysis in a large sample of British female twins (N = 4,426 who completed a questionnaire assessing sexual attraction, CGT and AGI. Univariate genetic models indicated modest genetic influences on sexual attraction (25%, AGI (11% and CGT (31%. For the multivariate analyses, a common pathway model best fitted the data. CONCLUSIONS/SIGNIFICANCE: This indicated that a single latent variable influenced by a genetic component and common non-shared environmental component explained the association between the three traits but there was substantial measurement error. These findings highlight common developmental factors affecting differences in sexual orientation.

    This study assessed the accuracy of a selected formula used to estimate the appendicular muscle mass (AMM) which is linked with many clinical outcomes. A group of community-dwelling adult women (n=80) had their AMM measured using dual energy x-ray absorptiometry (DXA). The same was estimated using a formula already published {Skeletal muscle mass = (0.244 × BW in kg) + (7.80 × Ht in meters) + (6.6 × Sex) - (0.098 × Age) + race - 3.3} (sex=0 for female and 1 for male, race =-1.2 for Asian, 1.4 for African American and 0 for White and Hispanic).The two datasets were compared for accuracy and precision. Mean AMM measured by DXA and estimated by the formula were very close (14.8 and 14.5 kg) and the difference ranged from -1.2 to 3.6 kg. Correlation between the two datasets was high (r=0.92) and the Bland-Altman plot showed an acceptable measurement agreement between the two methods. Results were independent of age and BMI. The formula used in this analysis gave an accurate estimation of the absolute AMM in women included in this study. PMID:26520864

    The NASA Decadal Survey (2011) emphasized the importance of long duration rodent experiments on the International Space Station (ISS). To accomplish this objective, flight hardware and science capabilities supporting mouse studies in space were developed at Ames Research Center. Here we present a video-based behavioral analysis of ten C57BL6 female adult mice exposed to a total of 37 days in space compared with identically housed Ground Controls. Flight and Control mice exhibited the same range of behaviors, including feeding, drinking, exploratory behavior, grooming, and social interactions. Mice propelled themselves freely and actively throughout the Habitat using their forelimbs to push off or by floating from one cage area to another. Overall activity was greater in Flt as compared to GC mice. Spontaneous, organized circling or race-tracking behavior emerged within the first few days of flight and encompassed the primary dark cycle activity for the remainder of the experiment. I will summarize qualitative observations and quantitative comparisons of mice in microgravity and 1g conditions. Behavioral phenotyping revealed important insights into the overall health and adaptation of mice to the space environment, and identified unique behaviors that can guide future habitat development and research on rodents in space.

    The cattle tick, Rhipicephalus microplus, has a debilitating effect on the livestock industry worldwide, owing to its being a vector of the causative agents of bovine babesiosis and anaplasmosis. In South Africa, co-infestation with R. microplus and R. decoloratus, a common vector species on local livestock, occurs widely in the northern and eastern parts of the country. An alternative to chemical control methods is sought in the form of a tick vaccine to control these tick species. However, sequence information and transcriptional data for R. decoloratus is currently lacking. Therefore, this study aimed at identifying genes that are shared between midgut tissues of feeding adult female R. microplus and R. decoloratus ticks. In this regard, a custom oligonucleotide microarray comprising of 13,477 R. microplus sequences was used for transcriptional profiling and 2476 genes were found to be shared between these Rhipicephalus species. In addition, 136 transcripts were found to be more abundantly expressed in R. decoloratus and 1084 in R. microplus. Chi-square analysis revealed that genes involved in lipid transport and metabolism are significantly overrepresented in R. microplus and R. decoloratus. This study is the first transcriptional profiling of R. decoloratus and is an additional resource that can be evaluated further in future studies for possible tick control. PMID:25448423

  1. FASH and MASH: female and male adult human phantoms based on polygon mesh surfaces: I. Development of the anatomy

    International Nuclear Information System (INIS)

    Among computational models, voxel phantoms based on computer tomographic (CT), nuclear magnetic resonance (NMR) or colour photographic images of patients, volunteers or cadavers have become popular in recent years. Although being true to nature representations of scanned individuals, voxel phantoms have limitations, especially when walled organs have to be segmented or when volumes of organs or body tissues, like adipose, have to be changed. Additionally, the scanning of patients or volunteers is usually made in supine position, which causes a shift of internal organs towards the ribcage, a compression of the lungs and a reduction of the sagittal diameter especially in the abdominal region compared to the regular anatomy of a person in the upright position, which in turn can influence organ and tissue absorbed or equivalent dose estimates. This study applies tools developed recently in the areas of computer graphics and animated films to the creation and modelling of 3D human organs, tissues, skeletons and bodies based on polygon mesh surfaces. Female and male adult human phantoms, called FASH (Female Adult meSH) and MASH (Male Adult meSH), have been designed using software, such as MakeHuman, Blender, Binvox and ImageJ, based on anatomical atlases, observing at the same time organ masses recommended by the International Commission on Radiological Protection for the male and female reference adult in report no 89. 113 organs, bones and tissues have been modelled in the FASH and the MASH phantoms representing locations for adults in standing posture. Most organ and tissue masses of the voxelized versions agree with corresponding data from ICRP89 within a margin of 2.6%. Comparison with the mesh-based male RPIAM and female RPIAF phantoms shows differences with respect to the material used, to the software and concepts applied, and to the anatomies created.

    Full Text Available BackgroundA limitation in the number of insulin-producing pancreatic beta-cells is a special feature of diabetes. The identification of alternative sources for the induction of insulin-producing surrogate beta-cells is a matter of profound importance. PDX-1/VP16, BETA2/NeuroD, and MafA overexpression have been shown to influence the differentiation and proliferation of pancreatic stem cells. However, few studies have been conducted using adult animal pancreatic stem cells.MethodsAdult pig pancreatic cells were prepared from the non-endocrine fraction of adult pig pancreata. Porcine neonatal pancreas cell clusters (NPCCs were prepared from neonatal pigs aged 1-2 days. The dispersed pancreatic cells were infected with PDX-1/VP16, BETA2/NeuroD, and MafA adenoviruses. After infection, these cells were transplanted under the kidney capsules of normoglycemic nude mice.ResultsThe adenovirus-mediated overexpression of PDX-1, BETA2/NeuroD and MafA induced insulin gene expression in NPCCs, but not in adult pig pancreatic cells. Immunocytochemistry revealed that the number of insulin-positive cells in NPCCs and adult pig pancreatic cells was approximately 2.6- and 1.1-fold greater than those in the green fluorescent protein control group, respectively. At four weeks after transplantation, the relative volume of insulin-positive cells in the grafts increased in the NPCCs, but not in the adult porcine pancreatic cells.ConclusionThese data indicate that PDX-1, BETA2/NeuroD, and MafA facilitate the beta-cell differentiation of NPCCs, but not adult pig pancreatic cells. Therefore PDX-1, BETA2/NeuroD, and MafA-induced NPCCs can be considered good sources for the induction of pancreatic beta-cells, and may also have some utility in the treatment of diabetes.

    Full Text Available Background: Globally, domestic violence against females is common across culture, religion, class and ethnicity. There are various reasons for domestic violence and it might have serious health outcomes. Objectives: The study was undertaken to determine the prevalence, characteristics, reasons and the socio-demographic correlates of domestic violence, if any, and to find out the perceptions of the females to cope with the act of violence and to overcome the situation. Materials and Methods: A cross-sectional observational study was undertaken by interviewing 141 adult and adolescent females residing in a village of West Bengal, with the help of a pre-designed and pre-tested questionnaire. Data were analyzed statistically by simple proportions and tests of significance (Chi-square test. Results: Out of 141 respondents, 33 (23.4% adult and adolescent females in this village were exposed to domestic violence in the past year. Among the demographic characteristics, statistically significant maximum prevalence was observed among 30-39 years age group, illiterate and unmarried females. For most of the females who were exposed to domestic violence, their husbands acted as the perpetrators (72.73% and they reported slapping as the specific act of physical assault (72.73%. Majority of the respondents reported that opportunity of education (31.9%, being economically productive (31.9% and better family income (23.4% would help them to overcome the situation. Conclusion: This study emphasizes the need for justified female empowerment and this calls for multidisciplinary approach to develop public health measures, which would most effectively address the problem of domestic violence.

    During processing of foods, the Maillard reaction occurs, resulting in the formation of advanced Maillard reaction products (MRP). Varying amounts of MRP have been found in commercially processed pet foods. Dietary MRP can be absorbed and contribute to the endogenous pool of MRP and possibly the etiology of age-related diseases. The aim of the present study was to determine urinary excretion of dietary MRP in cats fed commercial moist and dry foods. A pilot study with 10 cats, conducted to determine the adaptation time required for stable urinary excretion of MRP when changing to a diet with contrasting MRP content, showed an adaptation time of 1 d for all components. In the main study, 6 commercially processed dry and 6 moist diets were fed to 12 adult female cats in 2 parallel randomized, 36-d Latin square designs. The 24-h urine was collected quantitatively using modified litter boxes, and fructoselysine (FL), carboxymethyllysine (CML), and lysinoalanine (LAL) were analyzed using ultra high performance liquid chromatography (UHPLC) - mass spectrometer. Daily urinary excretion of FL and CML showed a positive relationship with daily intake in the dry ( = 0.03 and MRP were absorbed from the gastrointestinal tract of cats and excreted in the urine. The adaptation time with change in diet indicates a likely effective excretion of MRP. Minimum apparent absorption of FL, CML, and LAL was found to range between 8% and 23%, 25% and 73%, and 6% and 19%, respectively. The observed decrease in urinary recovery suggests a limiting factor in digestion, absorption, metabolism, or urinary excretion. This study shows that dietary MRP in commercial diets are absorbed and excreted via the kidneys in cats. PMID:26812325

    For many marine species, locations of migratory pathways are not well defined. We used satellite telemetry and switching state-space modeling (SSM) to define the migratory corridor used by Kemp's ridley turtles (Lepidochelys kempii) in the Gulf of Mexico. The turtles were tagged after nesting at Padre Island National Seashore, Texas, USA from 1997 to 2014 (PAIS; n = 80); Rancho Nuevo, Tamaulipas, Mexico from 2010 to 2011 (RN; n = 14); Tecolutla, Veracruz, Mexico from 2012 to 2013 (VC; n = 13); and Gulf Shores, Alabama, USA during 2012 (GS; n = 1). The migratory corridor lies in nearshore Gulf of Mexico waters in the USA and Mexico with mean water depth of 26 m and a mean distance of 20 km from the nearest mainland coast. Migration from the nesting beach is a short phenomenon that occurs from late-May through August, with a peak in June. There was spatial similarity of post-nesting migratory pathways for different turtles over a 16 year period. Thus, our results indicate that these nearshore Gulf waters represent a critical migratory habitat for this species. However, there is a gap in our understanding of the migratory pathways used by this and other species to return from foraging grounds to nesting beaches. Therefore, our results highlight the need for tracking reproductive individuals from foraging grounds to nesting beaches. Continued tracking of adult females from PAIS, RN, and VC nesting beaches will allow further study of environmental and bathymetric components of migratory habitat and threats occurring within our defined corridor. Furthermore, the existence of this migratory corridor in nearshore waters of both the USA and Mexico demonstrates that international cooperation is necessary to protect essential migratory habitat for this imperiled species.

    Many flesh fly species are anautogenous. Due to their life style, these flies have a negative impact on livestock since they can cause myiasis. Anautogeny is a kind of reproductive strategy, where adult female insects requirea proteinaceous meal in order to initiate vitellogenesis - the large scale synthesis of yolk proteins and their subsequent uptake by the developing oocytes. The expression of yolk protein precursor genes is tightly controlled by the nutritional state of the organism. I...

    Adult male ruminants that were reared in contact with females display greater sexual behavior than those reared in single male groups. The aim of the experiment was to compare the reproductive development of prepubertal male kids reared with or without direct permanent contact with adult females until they were 10 months old. Seventeen Saanen male kids were maintained in two groups until 44 weeks of age: kids reared in permanent direct contact with four adult goats (group FEM, N = 8) and kids that remained isolated from females (group ISO, N = 9). All goats in the FEM group became pregnant approximately when bucks attained 28 weeks of age. Scrotal circumference and testosterone concentration were measured, and semen was obtained by electroejaculation to avoid female contact in the ISO group. Scrotal circumference was greater in FEM kids at 12 and 14 weeks of age (P < 0.0001) and testosterone when they were 20 and 22 weeks old (P < 0.0001). Testosterone concentration was greater in ISO kids from 28 to 44 weeks of age. All semen characteristics increased with age (P < 0.0001). Individual motility was greater in FEM kids than that in ISO kids at 15 and 17 weeks (P < 0.005); mass motility was greater in ISO than that in FEM kids at 32 weeks (P < 0.05); total number of spermatozoa/ejaculate was greater in ISO kids at 30, 32, and 40 weeks and in FEM kids at 43 weeks (P < 0.005); total number of motile spermatozoa was greater in ISO kids at 32 and 40 weeks, whereas at 43 weeks, it was greater in FEM kids (P < 0.005). It was concluded that permanent contact with adult goats had transient and short-time positive effects in male kids' reproductive traits during prepubertal development. However, positive effects stopped after goats used as stimulus became pregnant. PMID:25277528

    Phthalate esters (PE) are synthetic chemicals widely used in industry, and have been detected in personal care products (PCP). Recent findings of human reports demonstrated endocrine-disrupting action associated with phthalate exposures. The aims of this study were to (1) measure levels of 11 PE in 198 PCP collected from retail markets in Shanghai and (2) assess daily dermal exposure in adult females and infants. The health risk of cumulative exposure to eight PE on reproductive system function derived from dermal PCP use was further assessed by utilizing the hazard index (HI) approach. Diethyl phthalate (DEP) was the most frequently detected compound (29.8%), followed by diisobutyl phthalate (DiBP) (6.6%). The geometric mean (GM) concentrations of daily exposure to DEP, bis(2-methoxyethyl) phthalate (DMEP), DiBP, dibutyl phthalate (DBP), diphenyl phthalate (DPP), and bis(2-ethylhexyl) phthalate (DEHP) in female adults were 0.018, 0.012, 0.002, 0.001, 0.003, and 0.002 μg/kg body weight (bw)/d, respectively. The GM daily exposure levels to PE in infants and adult females were similar except for DEHP, which was higher in infants. DEP exposure was highest in both subpopulations at either GM or maximal level. All HI of 8 PE were far less than 1, ranging from 0.0002 to 0.005, indicating no cumulative reproductive risks to these populations. DBP, DMEP, and DEHP were three major contributors to the cumulative HI. In summary, the level of phthalate in PCP from Shanghai retail markets posed no apparent cumulative risk to adult females and infants in China. PMID:25734628

    DEHP, one of the most commonly phthalates used in plastics and many other products, is an environmental endocrine disruptor (EED). Puberty is another critical period for the brain development besides the neonatal period and is sensitive to EEDs. Social behavior is organized during puberty, so the present study is to investigate whether pubertal exposure to DEHP influenced social behavior of adult female mice. The results showed that pubertal exposure to DEHP for 2 weeks did not change the serum level of 17β-estradiol and the weight of uterus of adult females, but decreased the number of grid crossings and the frequency of rearing, and increased grooming in open field. DEHP reduced the open arm entries and the time spent in open arms in the elevated plus maze. DEHP reduced mutual sniffing and grooming between unfamiliar conspecifics in social play task and reduced the right chamber (containing unfamiliar female mouse) entries and the frequency of sniffing unfamiliar female mouse. DEHP at 1 mg kg(-1) d(-1) reduced the time spent in right chamber. Furthermore, Western blot analyses showed that DEHP decreased the levels of estrogen receptor β (ERβ), dopamine receptor D2, and the phosphorylation of ERKs in striatum. These results suggest that pubertal exposure to DEHP impaired social investigation and sociability and influenced anxiety-like state of adult female mice. The decreased activity of ERK1/2, and the down-regulated D2 and ERβ in striatum may be associated with the DEHP-induced changes of emotional and social behavior in mice. PMID:26524146

    Full Text Available Background: The effect of monosodium glutamate used as food additive on the fallopian tubes of adult Wistar rat was investigated. Material and Methods: Adult female Wistar rats (n=24 of average weight of 230g were randomly assigned into three groups A, B and C in each group (n=8. The treatment groups (A & B were given 0.04mg/kg and 0.08mg/kg of monosodium glutamate thoroughly mixed with the growers′ mash, respectively on a daily basis. The control group (C received equal amount of feeds (Growers′ mash without monosodium glutamate added for fourteen days. The growers′ mash was obtained from Edo Feeds and Flour Mill Ltd, Ewu, Edo State and the rats were given water liberally. The rats were sacrificed on day fifteen of the experiment. The fallopian tubes were carefully dissected out and quickly fixed in 10% buffered formaldehyde for routine histological procedures. Result: The histological findings in the treated groups showed evidence of cellular hypertrophy, degenerative and atrophic changes, and lysed red blood cells in lumen with the group that received 0.08mg/kg of monosodium glutamate more severe. Conclusion: MSG may have some deleterious effects on the fallopian tubes of adult female Wistar rats at higher doses and by extension may contribute to the causes of female infertility. It is recommended that further studies aimed at corroborating these findings be carried out.

  15. Effects on transcriptional regulation and lipid droplet characteristics in the liver of female juvenile pigs after early postnatal feed restriction and refeeding are dependent on birth weight.

    Full Text Available Epidemiological and experimental data indicate that caloric restriction in early postnatal life may improve liver lipid metabolism in low birth weight individuals. The present study investigated transcriptional and metabolic responses to low (U and normal (N birth weight (d 75, T1 and postnatal feed restriction (R, 60% of controls, d 98, T2 followed by subsequent refeeding until d 131 of age (T3. Liver tissue studies were performed with a total of 42 female pigs which were born by multiparous German landrace sows. Overall, 194 genes were differentially expressed in the liver of U vs. N (T1 animals with roles in lipid metabolism. The total mean area and number of lipid droplets (LD was about 4.6- and 3.7 times higher in U compared to N. In U, the mean LD size (µm(2 was 24.9% higher. 3-week feed restriction reduced total mean area of LDs by 58.3 and 72.7% in U and N, respectively. A functional role of the affected genes in amino acid metabolism was additionally indicated. This was reflected by a 17.0% higher arginine concentration in the liver of UR animals (vs. NR. To evaluate persistency of effects, analyses were also done after refeeding period at T3. Overall, 4 and 22 genes show persistent regulation in U and N animals after 5 weeks of refeeding, respectively. These genes are involved in e.g. processes of lipid and protein metabolism and glucose homeostasis. Moreover, the recovery of total mean LD area in U and N animals back to the previous T1 level was observed. However, when compared to controls, the mean LD size was still reduced by 23.3% in UR, whereas it was increased in NR (+24.7%. The present results suggest that short-term postnatal feed restriction period programmed juvenile U animals for an increased rate of hepatic lipolysis in later life.

    Full Text Available Abstract Background Chemical immobilization of Weddell seals (Leptonychotes weddellii has previously been, for the most part, problematic and this has been mainly attributed to the type of immobilizing agent used. In addition to individual sensitivity, physiological status may play an important role. We investigated the use of the intravenous administration of a 1:1 mixture of tiletamine and zolazepam (Telazol® to immobilize adult females at different points during a physiologically demanding 5–6 week lactation period. We also compared performance between IV and IM injection of the same mixture. Results The tiletamine:zolazepam mixture administered intravenously was an effective method for immobilization with no fatalities or pronounced apnoeas in 106 procedures; however, there was a 25 % (one animal in four mortality rate with intramuscular administration. Induction time was slightly longer for females at the end of lactation (54.9 ± 2.3 seconds than at post-parturition (48.2 ± 2.9 seconds. In addition, the number of previous captures had a positive effect on induction time. There was no evidence for effects due to age, condition (total body lipid, stage of lactation or number of captures on recovery time. Conclusion We suggest that intravenous administration of tiletamine and zolazepam is an effective and safe immobilizing agent for female Weddell seals. Although individual traits could not explain variation in recovery time, we suggest careful monitoring of recovery times during longitudinal studies (> 2 captures. We show that physiological pressures do not substantially affect response to chemical immobilization with this mixture; however, consideration must be taken for differences that may exist for immobilization of adult males and juveniles. Nevertheless, we recommend a mass-specific dose of 0.50 – 0.65 mg/kg for future procedures with adult female Weddell seals and a starting dose of 0.50 mg/kg for other age classes and other

    In this study, a spectrographic analysis was designed to improve the description of the shape, the modulations, the rate, length and frequencies of BALB/c mouse calls in different behavioural situations. Male and female calls emitted during investigation of cages with clean bedding, soiled with male or female bedding, and during same-sex encounters, were recorded and described. BALB/c male mice uttered different types of vocalisations both when investigating counterpart odour cues and when interacting with same-sex counterparts. BALB/c female mice vocalised solely during same-sex counterpart encounters and it appeared that calls were uttered mainly by the resident females. Male and female mice present a complex array of calls, which seem to be linked to particular behavioural situations. Further studies using this technology may help to improve our understanding of the role of vocal communication in natural rodent populations.

    Mathematical phantoms representing the adult female at three, six, and nine months of gestation are described. They are modifications of the 15-year-old male/adult female phantom (15-AF phantom) of Cristy and Eckerman (1987). The model of uterine contents includes the fetus, fetal skeleton, and placenta. The model is suitable for dose calculations for the fetus as a whole; individual organs within the fetus (other than the skeleton) are not modeled. A new model for the nonpregnant adult female is also described, comprising (1) the 15-AF phantom; (2) an adjustment to specific absorbed fractions for organ self-dose from photons to better match Reference Woman masses; and (3) computation of specific absorbed fractions with Reference Woman masses from ICRP Publication 23 for both penetrating and nonpenetrating radiations. Specific absorbed fractions for photons emitted from various source regions are tabulated for the new non;pregnant adult female model and the three pregnancy models.

    1998-01-01

    During 1991-1993, we conducted capture-recapture studies on pig frogs, Rana grylio, in seven study locations in northcentral Florida. Resulting data were used to test hypotheses about variation in survival probability over different size-sex classes of pig frogs. We developed multistate capture-recapture models for the resulting data and used them to estimate survival rates and frog abundance. Tests provided strong evidence of survival differences among size-sex classes, with adult females showing the highest survival probabilities. Adult males and juvenile frogs had lower survival rates that were similar to each other. Adult females were more abundant than adult males in most locations at most sampling occasions. We recommended probabilistic capture-recapture models in general, and multistate models in particular, for robust estimation of demographic parameters in amphibian populations.

  9. Decreased duration of pentobarbital-induced narcosis in immature and adult female rats prenatally exposed to cimetidine

    International Nuclear Information System (INIS)

    The effect of prenatal cimetidine exposure (PreCM) on the duration of pentobarbital-induced narcosis (DPN) was assessed in immature (14- and 28-day old) and adult (50-60-day old) male and female rats. PreCM exposure was accomplished by treating mothers with cimetidine (CM) (20 mg/kg, ip) daily for the last two days of gestation and then (0.01% in drinking water) throughout lactation. Pregnant mothers of untreated offspring (Con) received saline. PreCM decreased DPN to 505 +/- 33 min (from 611 +/- 23 min in Con) and 393 +/- 190 min (from 686 +/- 44 min in Con) in 14-day old male and female rats, respectively. Similarly, PreCM decreased DPN to 88 +/- 15 min (from 134 +/- 3 min in Con) and 102 +/- 19 min (from 171 +/- 44 min in Con) in 28-day old male and female rats, respectively. At 21 days, PreCM did not alter DPN in either sex. At 50-60 days, however, it decreased DPN to 144 +/- 41 min (from 238 +/- 7 min in Con) in females but had no effect in males; PreCM also increased the plasma clearance of administered 14C-pentobarbital more in females than in males. The effects of PreCM, particularly the long-term effects, were most prominent in female rats and were the opposite of those of postnatal treatment with CM. The results together with those of studies with hepatic microsomes suggest that PreCM may have resulted in the induction of hepatic drug-metabolizing enzymes during the perinatal period

    Adolescence is a period of substantial neuroplasticity in stress regulatory neurocircuits. Chronic stress exposure during this period leads to long-lasting changes in neuroendocrine function and emotional behaviors, suggesting adolescence may be a critical period for development of stress vulnerability. This study investigated the effects of exposure to 14 days of chronic variable stress (CVS) in late-adolescent (pnd 45-58) female rats on neuroendocrine function, neuropeptide mRNA expression and depressive-like behavior in adolescence (pnd 59) and in adulthood (pnd 101). Adult females exposed to CVS in adolescence have a blunted hypothalamo-pituitary-adrenocortical (HPA) axis in response to a novel stressor and increased immobility in the forced swim test. Blunted HPA axis responses were accompanied by reduced vasopressin mRNA expression in the paraventricular nucleus of the hypothalamus (PVN), suggesting decreased central drive. Adolescent females tested immediately after CVS did not exhibit differences in stress reactivity or immobility in the forced swim test, despite evidence for enhanced central HPA axis drive (increased CRH mRNA expression in PVN). Overall, our study demonstrates that exposure to chronic stress in adolescence is sufficient to induce lasting changes in neuroendocrine drive and behavior, potentially altering the developmental trajectory of stress circuits as female rats age into adulthood.

    When competing for mates, males typically exhibit higher rates of intrasexual aggression and courtship than females. Operational sex ratio, represented here by adult sex ratio (ASR) as a proxy, is likely the best predictor of this competition, which typically increases between members of one sex as members of the opposite sex become rarer. Moreover, in populations subject to high predation, males often decrease mating competitive behaviour due to predation risk. We explored the combined effects of ASR and population of origin (low vs. high ambient predation risk) on mating competition in male and female wild-caught Trinidadian guppies. Both male and female aggression rates increased with ASR, but the increase for males was only significant in the low-predation population. In regard to male mating tactics, courtship propensity was unaffected by ASR, while the propensity to sneak increased at male-biased ASRs. Guppies from a high predation population had lower aggression rates than their low predation counterpart, but male courtship and sneaking attempts did not differ between populations. Surprisingly, females were just as aggressive as males when competing for mates. These results highlight the trade-offs between antipredator and agonistic behaviour, which may affect sexual selection pressures in wild populations. PMID:27208810

    Infanticide by males is a common phenomenon in mammals,especially primates,as lactation lasts much longer than gestation in many species.Usually,infanticidal episodes occur soon after group takeovers,and are traditionally considered a male reproductive strategy (i.e.,support the sexual selection hypothesis,Hrdy,1974).To verify the validity of this conception,we observed one group of Fran(c)ois' langurs in the Nonggang Nature Reserve,China,between August 2003 and July 2004.During the study period,a Fran(c)ois' langur female with the youngest infant in the group was attacked three times by immigrating males,and later disappeared by the third day after the final attack.We suggest that these attacks on the female-infant dyad represent infanticide attempts by males,and may be the cause of the adult female and her infant's disappearance.Presumably,that female dispersed with her infant to avoid infanticide and was not killed.Though these observations do not completely verify the sexual selection hypothesis,they are not inconsistent with it.

    In recent years, the use of hormonal contraception in captive, free-ranging, and wild mammal populations has increased, but the effects on these nonhuman animals' behavior and the associated welfare impacts remain poorly understood. This study of free-ranging adult female Barbary macaques (Macaca sylvanus) at Trentham Monkey Forest compared females implanted with the progestin-only contraceptive Implanon to those not receiving contraception. Females with contraceptive implants had higher rates of self-scratching and spent more time self-grooming (2 behavioral indexes of anxiety) than those without implants. They also directed more aggression at others, spent more time receiving grooming and traveling, and spent less time giving grooming and resting. No significant differences between the 2 groups of females were seen for time spent foraging. These results suggest that Implanon had a number of effects on Barbary macaques, although these need to be considered in light of the significant benefits afforded by the use of this contraceptive. The findings of this study provide important information to those evaluating the relative welfare costs and benefits of alternative methods of population control in this and other species.

    The notion of animal culture has been well established mainly through research aiming at uncovering differences between populations. In chimpanzees (Pan troglodytes verus), cultural diversity has even been found in neighboring communities, where differences were observed despite frequent immigration of individuals. Female chimpanzees transfer at the onset of sexual maturity at an age, when the behavioral repertoire is fully formed. With immigrating females, behavioral variety enters the group. Little is known about the diversity and the longevity of cultural traits within a community. This study is building on previous findings of differences in hammer selection when nut cracking between neighboring communities despite similar ecological conditions. We now further investigated the diversity and maintenance of cultural traits within one chimpanzee community and were able to show high levels of uniformity in group-specific behavior. Fidelity to the behavior pattern did not vary between dispersing females and philopatric males. Furthermore, group-specific tool selection remained similar over a period of 25 years. Additionally, we present a study case on how one newly immigrant female progressively behaved more similar to her new group, suggesting that the high level of similarity in behavior is actively adopted by group members possibly even when originally expressing the behavior in another form. Taken together, our data support a cultural transmission process in adult chimpanzees, which leads to persisting cultural behavior of one community over time. PMID:24482055

    Individuals within populations often differ substantially in habitat use, the ecological consequences of which can be far reaching. Stable isotope analysis provides a convenient and often cost effective means of indirectly assessing the habitat use of individuals that can yield valuable insights into the spatiotemporal distribution of foraging specialisations within a population. Here we use the stable isotope ratios of southern sea lion (Otaria flavescens) pup vibrissae at the Falkland Islands, in the South Atlantic, as a proxy for adult female habitat use during gestation. A previous study found that adult females from one breeding colony (Big Shag Island) foraged in two discrete habitats, inshore (coastal) or offshore (outer Patagonian Shelf). However, as this species breeds at over 70 sites around the Falkland Islands, it is unclear if this pattern is representative of the Falkland Islands as a whole. In order to characterize habitat use, we therefore assayed carbon (δ13C) and nitrogen (δ15N) ratios from 65 southern sea lion pup vibrissae, sampled across 19 breeding colonies at the Falkland Islands. Model-based clustering of pup isotope ratios identified three distinct clusters, representing adult females that foraged inshore, offshore, and a cluster best described as intermediate. A significant difference was found in the use of inshore and offshore habitats between West and East Falkland and between the two colonies with the largest sample sizes, both of which are located in East Falkland. However, habitat use was unrelated to the proximity of breeding colonies to the Patagonian Shelf, a region associated with enhanced biological productivity. Our study thus points towards other factors, such as local oceanography and its influence on resource distribution, playing a prominent role in inshore and offshore habitat use. PMID:27304855

    Aggressive and sexual behavior in the adult leopard gecko (Eublepharis macularius), a species with temperature-dependent sex determination (TSD), is influenced by the temperature experienced as an egg, as well as by prenatal and perinatal hormones. This study focused on the effects of hormonal manipulation of adult female leopard geckos from different incubation temperatures. Following ovariectomy, females from both all-female (26 degrees C) and male-biased (32.5 degrees C) incubation temperatures exhibited a significant decrease in high-posture (HP) aggression toward male and female stimulus animals. Testosterone treatment attenuated this decrease in HP aggression toward female but not toward male stimulus animals. Ovariectomy also resulted in a loss in attractiveness in both groups of females. Following treatment with testosterone, over 50% of the females were attacked by male stimulus animals, suggesting a change in the pheromonal cues normally secreted by females. Unmanipulated females never exhibit tail vibrations, a male-typical courtship behavior. However, following ovariectomy with testosterone treatment, half of the females from both incubation temperatures exhibited this behavior, indicating an activational effect of testosterone. An effect of incubation temperature on aggression was evident with females from the male-biased incubation temperature exhibiting a greater likelihood of aggression compared to females from the all-female incubation temperature. This effect continued to be detected after hormone manipulation. Ovariectomized females from the all-female incubation temperature were less aggressive even with testosterone treatment toward males, whereas females from the male-biased incubation temperature showed no significant decline in aggression following testosterone treatment, suggesting that individuals from different incubation temperatures may have different sensitivities to hormones.

  19. Prenatal ethanol exposure programs an increased susceptibility of non-alcoholic fatty liver disease in female adult offspring rats

    International Nuclear Information System (INIS)

    Prenatal ethanol exposure (PEE) induces dyslipidemia and hyperglycemia in fetus and adult offspring. However, whether PEE increases the susceptibility to non-alcoholic fatty liver disease (NAFLD) in offspring and its underlying mechanism remain unknown. This study aimed to demonstrate an increased susceptibility to high-fat diet (HFD)-induced NAFLD and its intrauterine programming mechanisms in female rat offspring with PEE. Rat model of intrauterine growth retardation (IUGR) was established by PEE, the female fetus and adult offspring that fed normal diet (ND) or HFD were sacrificed. The results showed that, in PEE + ND group, serum corticosterone (CORT) slightly decreased and insulin-like growth factor-1 (IGF-1) and glucose increased with partial catch-up growth; In PEE + HFD group, serum CORT decreased, while serum IGF-1, glucose and triglyceride (TG) increased, with notable catch-up growth, higher metabolic status and NAFLD formation. Enhanced liver expression of the IGF-1 pathway, gluconeogenesis, and lipid synthesis as well as reduced expression of lipid output were accompanied in PEE + HFD group. In PEE fetus, serum CORT increased while IGF-1 decreased, with low body weight, hyperglycemia, and hepatocyte ultrastructural changes. Hepatic IGF-1 expression as well as lipid output was down-regulated, while lipid synthesis significantly increased. Based on these findings, we propose a “two-programming” hypothesis for an increased susceptibility to HFD-induced NAFLD in female offspring of PEE. That is, the intrauterine programming of liver glucose and lipid metabolic function is “the first programming”, and postnatal adaptive catch-up growth triggered by intrauterine programming of GC-IGF1 axis acts as “the second programming”. - Highlights: • Prenatal ethanol exposure increase the susceptibility of NAFLD in female offspring. • Prenatal ethanol exposure reprograms fetal liver’s glucose and lipid metabolism . • Prenatal ethanol exposure cause

  6. HDRK-Woman: whole-body voxel model based on high-resolution color slice images of Korean adult female cadaver

    International Nuclear Information System (INIS)

    In a previous study, we constructed a male reference Korean phantom; HDRK-Man (High-Definition Reference Korean-Man), to represent Korean adult males for radiation protection purposes. In the present study, a female phantom; HDRK-Woman (High-Definition Reference Korean-Woman), was constructed to represent Korean adult females. High-resolution color photographic images obtained by serial sectioning of a 26 year-old Korean adult female cadaver were utilized. The body height and weight, the skeletal mass, and the dimensions of the individual organs and tissues were adjusted to the reference Korean data. The phantom was then compared with the International Commission on Radiological Protection (ICRP) female reference phantom in terms of calculated organ doses and organ-depth distributions. Additionally, the effective doses were calculated using both the HDRK-Man and HDRK-Woman phantoms, and the values were compared with those of the ICRP reference phantoms. (paper)

    Vitamin D deficiency can lead to several health problems collectively called metabolic bone disease (MBD). One commonly kept reptile species prone to develop MBD if managed incorrectly is the bearded dragon (Pogona vitticeps). This study aimed to determine the extent to which adult female bearded dragons fed a diet low in vitamin D can use stored vitamin D and its metabolites to maintain plasma 25(OH)D(3) and 1,25(OH)(2)D(3) concentrations after discontinuing UVb exposure. Blood samples of healthy adult female bearded dragons, exposed to UVb radiation for over 6 months were collected (day 0) after which UVb exposure was discontinued for 83 days and blood was collected. Blood plasma was analysed for concentrations of total Ca, total P, ionized Ca, uric acid, 25(OH)D(3) and 1,25(OH)(2)D(3). There was no significant change in plasma 25(OH)D(3) and 1,25(OH)(2)D(3) concentrations during the study. While total Ca and P in whole blood was found to significantly decrease over time (P bearded dragons, previously exposed to UVb, are able to maintain blood vitamin D metabolite concentrations when UVb exposure is discontinued for a period of up to 83 days.

    2011-05-01

    Full Text Available Abstract Background The mosquito Aedes aegypti, vector of dengue fever, is a target for control by entomopathogenic fungi. Recent studies by our group have shown the susceptibility of adult A. aegypti to fungal infection by Metarhizium anisopliae. This fungus is currently being tested under field conditions. However, it is unknown whether blood-fed A. aegypti females are equally susceptible to infection by entomopathogenic fungi as sucrose fed females. Insect populations will be composed of females in a range of nutritional states. The fungus should be equally efficient at reducing survival of insects that rest on fungus impregnated surfaces following a blood meal as those coming into contact with fungi before host feeding. This could be an important factor when considering the behavior of A. aegypti females that can blood feed on multiple hosts over a short time period. Methods Female A. aegypti of the Rockefeller strain and a wild strain were infected with two isolates of the entomopathogenic fungus M. anisopliae (LPP 133 and ESALQ 818 using an indirect contact bioassay at different times following blood feeding. Survival rates were monitored on a daily basis and one-way analysis of variance combined with Duncan's post-hoc test or Log-rank survival curve analysis were used for statistical comparisons of susceptibility to infection. Results Blood feeding rapidly reduced susceptibility to infection, determined by the difference in survival rates and survival curves, when females were exposed to either of the two M. anisopliae isolates. Following a time lag which probably coincided with digestion of the blood meal (96-120 h post-feeding, host susceptibility to infection returned to pre-blood fed (sucrose fed levels. Conclusions Reduced susceptibility of A. aegypti to fungi following a blood meal is of concern. Furthermore, engorged females seeking out intra-domicile resting places post-blood feeding, would be predicted to rest for prolonged

  10. Estradiol and GPER Activation Differentially Affect Cell Proliferation but Not GPER Expression in the Hippocampus of Adult Female Rats.

    Directory of Open Access Journals (Sweden)

    Paula Duarte-Guterman

    Full Text Available Estradiol increases cell proliferation in the dentate gyrus of the female rodent but it is not known whether the G protein-coupled estrogen receptor (GPER, a membrane receptor, is involved in this process, nor whether there are regional differences in estradiol's effects on cell proliferation. Thus, we investigated whether estradiol exerts its effects on cell proliferation in the dorsal and ventral dentate gyrus through GPER, using the GPER agonist, G1, and antagonist, G15. Ovariectomized adult female rats received a single injection of either: 17β-estradiol (10 μg, G1 (0.1, 5, 10 μg, G15 (40 μg, G15 and estradiol, or vehicle (oil, DMSO, or oil+DMSO. After 30 min, animals received an injection of bromodeoxyuridine (BrdU and were perfused 24 h later. Acute treatment with estradiol increased, while the GPER agonist G1 (5 μg decreased, the number of BrdU+ cells in the dentate gyrus relative to controls. The GPER antagonist, G15 increased the number of BrdU+ cells relative to control in the dorsal region and decreased the number of BrdU+ cells in the ventral region. However, G15 treatment in conjunction with estradiol partially eliminated the estradiol-induced increase in cell proliferation in the dorsal dentate gyrus. Furthermore, G1 decreased the expression of GPER in the dentate gyrus but not the CA1 and CA3 regions of the hippocampus. In summary, we found that activation of GPER decreased cell proliferation and GPER expression in the dentate gyrus of young female rats, presenting a potential and novel estrogen-independent role for this receptor in the adult hippocampus.

    This study investigated whether undifferentiated germ and/or somatic stem cells remain in the differentiated ovary of a species that does not undergo sex changes under natural conditions and retain their sexual plasticity. The effect of aromatase inhibitor (AI)-treatment on sexually mature female zebrafish was examined. A 5-month AI treatment caused retraction of the ovaries after which testes-like organs appeared, and cyst structures filled with spermatozoa-like cells were observed in sections of these tissues. Electron microscopic observations revealed that these cells appeared as large sperm heads without tails. Sperm formation was re-examined after changing the diet to an AI-free food. A large number of normal sperm were obtained after eight weeks, and no formation of ovarian tissue was observed. Artificial fertilization using sperm from the sex-changed females was successful. These results demonstrated that sex plasticity remains in the mature ovaries of this species.

  18. Personalised Prescription of Scalable High Intensity Interval Training to Inactive Female Adults of Different Ages.

    Directory of Open Access Journals (Sweden)

    Jacqueline L Mair

    Full Text Available Stepping is a convenient form of scalable high-intensity interval training (HIIT that may lead to health benefits. However, the accurate personalised prescription of stepping is hampered by a lack of evidence on optimal stepping cadences and step heights for various populations. This study examined the acute physiological responses to stepping exercise at various heights and cadences in young (n = 14 and middle-aged (n = 14 females in order to develop an equation that facilitates prescription of stepping at targeted intensities. Participants completed a step test protocol consisting of randomised three-minute bouts at different step cadences (80, 90, 100, 110 steps·min-1 and step heights (17, 25, 30, 34 cm. Aerobic demand and heart rate values were measured throughout. Resting metabolic rate was measured in order to develop female specific metabolic equivalents (METs for stepping. Results revealed significant differences between age groups for METs and heart rate reserve, and within-group differences for METs, heart rate, and metabolic cost, at different step heights and cadences. At a given step height and cadence, middle-aged females were required to work at an intensity on average 1.9 ± 0.26 METs greater than the younger females. A prescriptive equation was developed to assess energy cost in METs using multilevel regression analysis with factors of step height, step cadence and age. Considering recent evidence supporting accumulated bouts of HIIT exercise for health benefits, this equation, which allows HIIT to be personally prescribed to inactive and sedentary women, has potential impact as a public health exercise prescription tool.

    Human immunodeficiency virus (HIV) infection has been implicated as a trigger for various autoimmune diseases, one of which is dermatomyositis. This is a very rare autoimmune disease characterised by myopathy, typical cutaneous signs and variable systemic manifestations. To our knowledge, the association of this rare disease with HIV infection has not been previously reported in Nigeria. We therefore decided to report the case of a 40 year old HIV-1 infected Nigerian female who presented to u...

    Stepping is a convenient form of scalable high-intensity interval training (HIIT) that may lead to health benefits. However, the accurate personalised prescription of stepping is hampered by a lack of evidence on optimal stepping cadences and step heights for various populations. This study examined the acute physiological responses to stepping exercise at various heights and cadences in young (n = 14) and middle-aged (n = 14) females in order to develop an equation that facilitates prescription of stepping at targeted intensities. Participants completed a step test protocol consisting of randomised three-minute bouts at different step cadences (80, 90, 100, 110 steps·min-1) and step heights (17, 25, 30, 34 cm). Aerobic demand and heart rate values were measured throughout. Resting metabolic rate was measured in order to develop female specific metabolic equivalents (METs) for stepping. Results revealed significant differences between age groups for METs and heart rate reserve, and within-group differences for METs, heart rate, and metabolic cost, at different step heights and cadences. At a given step height and cadence, middle-aged females were required to work at an intensity on average 1.9 ± 0.26 METs greater than the younger females. A prescriptive equation was developed to assess energy cost in METs using multilevel regression analysis with factors of step height, step cadence and age. Considering recent evidence supporting accumulated bouts of HIIT exercise for health benefits, this equation, which allows HIIT to be personally prescribed to inactive and sedentary women, has potential impact as a public health exercise prescription tool.

    Epidemiological studies in humans and experimental work in rodents suggest that exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), a persistent environmental toxicant, is associated with incidence of heart disease. Although TCDD toxicity depends by and large on the aryl hydrocarbon receptor (AHR), the role of the cardiac AHR in TCDD induced cardiovascular disease is not well defined. To determine whether the Ahr gene mediates disruption of heart function by TCDD, we generated a cardiomyocyte-specific Ahr knockout mouse by crossing Ahr(fx/fx) mice with βMhc:cre/+ mice, in which expression of Cre recombinase is driven by the promoter of the βMhc (myosin heavy chain-beta) gene. Starting at three months of age, mice with cardiomyocyte-specific Ahr ablation were exposed to 1μg/kg/week of TCDD or control vehicle by oral gavage for an additional three months. Relative to unexposed controls, TCDD-exposure induced cardiomyocyte Ahr-independent changes in males but not females, including a significant increase in body weight, blood pressure, and cardiac hypertrophy and a decrease in cardiac ejection fraction. TCDD exposure also induced cardiomyocyte Ahr-dependent changes in fibrosis and calcium signaling gene expression in both males and females. TCDD exposure appears to cause sexually dimorphic effects on heart function and induce fibrosis and changes in calcium signaling in both males and females through activation of the cardiomyocyte-specific Ahr.

    The PIWI-interacting RNA (piRNA) pathway is essential for germline development and transposable element repression. Key elements of this pathway are members of the piRNA-binding PIWI/Argonaute protein family and associated factors (e.g., VASA, MAELSTROM, and TUDOR domain proteins). PIWI-interacting RNAs have been identified in mouse testis and oocytes, but information about the expression of the different piRNA pathway genes, in particular in the mammalian ovary, remains incomplete. We investigated the evolution and expression of piRNA pathway genes in gonads of amniote species (chicken, platypus, and mouse). Database searches confirm a high level of conservation and revealed lineage-specific gain and loss of Piwi genes in vertebrates. Expression analysis in mammals shows that orthologs of Piwi-like (Piwil) genes, Mael (Maelstrom), Mvh (mouse vasa homolog), and Tdrd1 (Tudor domain-containing protein 1) are expressed in platypus adult testis. In contrast to mouse, Piwil4 is expressed in platypus and human adult testis. We found evidence for Mael and Piwil2 expression in mouse Sertoli cells. Importantly, we show mRNA expression of Piwil2, Piwil4, and Mael in oocytes and supporting cells of human, mouse, and platypus ovary. We found no Piwil1 expression in mouse and chicken ovary. The conservation of gene expression in somatic parts of the gonad and germ cells of species that diverged over 800 million yr ago indicates an important role in adult male and female gonad.

  6. Characterization of Fiber Types in Different Muscles of the Hindlimb in Female Weanling and Adult Wistar Rats

    International Nuclear Information System (INIS)

    We analyzed lesser diameter and distribution of fiber types in different skeletal muscles from female Wistar rats using a histoenzymology Myofibrillar Adenosine Tri-phosphatase (mATPase) method. Fragments from muscles were frozen and processed by mATPase in different pH. Adult and weanling rat soleus muscles presented a predominance of type I fibers and larger fiber diameters. In the plantar muscle in adult rats, the type IIB fibers demonstrated greater lesser diameter while in the weanling animals, types I and IIB fibers were larger. The plantar muscle of animals of both ages was composed predominantly of the type IID fibers. The type IID fibers were observed in similar amounts in the lateral gastrocnemius and the medial gastrocnemius muscles. Type IIB fibers showed predominance and presented higher size in comparison with other types in the EDL muscle. The present study shows that data on fiber type distribution and fiber lesser diameter obtained in adult animals cannot always be applied to weanling animals of the same species. Using the mATPase, despite the difficult handling, is an important tool to determine the different characteristics of the specific fibers in the skeletal muscle tissue

    This research examines the ontogenic patterns of changes in growth during adolescence, pelvis variations and growth during twenties and thirties of age, structural remodeling of pelvis related to childbirth and relationship of pelvis area with physique based on the cross-sectional data on 391 females from the state of Haryana. Peak growth velocity for body height and breadths of skeletal traits occurred between 11 and 12 years, much before mean age of menarche at 13.5 years; while for body weight and body mass index (BMI) occurred between 14 and 15 years, after the mean age of menarche. Untill the age 11 years, 11.87% of growth in stature was remaining, 19.37% for bi-cristal breadth, 25.96% for bi-ischial breadth and 35.82% for pelvic area. The hypothesis of critical value of pelvic width of 240mm at iliocristale for menarche to occur has been only a statistical association. Higher prevalence of malnutrition during pubertal phase than pre- and post-pubertal phases was due to greater nutritional needs during puberty. Among adult females, BMI was very poorly correlated with stature but very strongly correlated with body breadths, body breadth-stature indices and body weight. The body mass and pelvis size continued to change during 20s and first half of 30s. The continued increase of BMI was due to increase in body fat and muscle mass in females 18 years and older. To tease apart age and parturition effects on pelvis variations, the analysis showed that pelvic bones remodeling took place after the first child was born and not after the subsequent births, and it was a sign of childbirth phenotypic plasticity rather than age. Pelvis area was strongly associated with stature, BMI and age. Mean pelvic area of tall females was greater than those of medium and short stature. Females with broad shoulders had significantly greater mean pelvis area than those with narrow shoulders and medium shoulders. Females having thin/lean physique had the smallest mean pelvis area

    PURPOSE: To assess the validity of spectrophotometric retinal oximetry, by comparison to blood gas analysis and intra-vitreal measurements of partial pressure of oxygen (pO2). METHODS: Female domestic pigs were used for all experiments (n=8). Oxygen fraction in inspired air was changed using a......, Reykjavik, Iceland). The device simultaneously acquires images at two wavelengths (570 nm and 600 nm) and specialized software automatically detects retinal blood vessels. In three pigs, invasive pO2-measurements were performed after the initial non-invasive measurements. RESULTS: Comparison of femoral......-measurements in three pigs. This relationship was approximately linear (R(2) = 0.45, p = 0.04). CONCLUSIONS: Non-invasive spectrophotometric oximetry is sensitive to changes in oxygen saturation in pigs and correlated with intravitreal pO2-measurements and with femoral artery pO2.

    The polyphagous Drosophila suzukii is a highly invasive species that causes extensive damage to a wide range of berry and stone fruit crops. A better understanding of its biology and especially its behaviour will aid the development of new control strategies. We investigated the locomotor behaviour of D. suzukii in a semi-natural environment resembling a typical summer in northern England and show that adult female D. suzukii are at least 4-fold more active during daylight hours than adult males. This result was reproduced in several laboratory environments and was shown to be a robust feature of mated, but not virgin, female flies. Both males and virgin females kept on a 12 h light:12 h dark (12LD) cycle and constant temperature displayed night-time inactivity (sleep) followed by weak activity in the morning, an afternoon period of quiescence (siesta) and then a prominent evening peak of activity. Both the siesta and the sharp evening peak at lights off were severely reduced in females after mating. Flies of either sex entrained in 12LD displayed a circadian pattern of activity in constant darkness confirming the importance of an endogenous clock in regulating adult activity. This response of females to mating is similar to that elicited in female Drosophila melanogaster by the male sex peptide (SP). We used mass spectrometry to identify a molecular ion (m/z, 5145) corresponding to the poly-hydroxylated SP of D. suzukii and to show that this molecule is transferred to the female reproductive tract during copulation. We propose that the siesta experienced by male and virgin female D. suzukii is an adaptation to avoid unnecessary exposure to the afternoon sun, but that mated females faced with the challenge of obtaining resources for egg production and finding oviposition sites take greater risks, and we suggest that the change in female behaviour is induced by the male SP.

    Full Text Available Anastomosis found in the adulthood between the carotid and vertebro - basilar systems, apart from the posterior communicating artery, are extremely infrequent and are due to the persistence of vessels that joined both systems during the fetal period. This carotid - vertebrobasilar anastomosis are the trigeminal, otic, and hypoglossal and proatlantal arteries. P ersistent trigeminal artery is the commonest of the above mentioned four arteries. The reported incidence is about 0.2%. Patients may be asymptomatic or present symptoms due to low flow of posterior circulation or carotid microembolization from posterior circulation. PTA can cause trigemina l neuralgia. We report in this paper a case of a persistant trigeminal artery found in an adult female with a para p com aneurysm who had persistent trigeminal artery which was seen in C T angiogram .

    Full Text Available We report on an adult female white shark tracked for 288 days and 7,100 km in the NE Pacific Ocean. The shark, tagged with a real-time satellite tag off Guadalupe Island, Mexico in October 2006, remained around the island for 3.5 months but left in early February 2007 for a ca. 3,900 km westward migration. Heading and swimming speed data showed that: a the arc-like route followed by this shark during oceanic travel involved strongly directional rapid movement, and b once the shark arrived to a specific (ca. 680 km wide area located 790 km north-northeast of the Hawaiian Islands, it switched into a distinct roaming behavior. The shark remained in this roaming area from late March to at least late July 2007. We show that real-time satellite tags can provide unique and valuable information about the migratory behavior of white sharks.

    The purpose of this study was to assess energy availability (EA) and dietary patterns of 10 adult (29-49 years) male (n = 6) and female (n = 4) competitive (USA Cycling Category: Pro, n = 2; 1-4, n = 8) endurance cyclists (5 road, 5 off-road), with lower than expected bone mineral density (BMD; Z score competition (C), and off-season (OS) were estimated from 3-day dietary records, completed once per month, across a cycling season. BMD was measured by DXA at 0 months/5 months/10 months. The Three-Factor Eating Questionnaire (TFEQ) was used to assess cognitive dietary restraint. Seventy percent of participants had low EA [(LEA); competitive road and off-road cyclists in the United States may be at risk for long-term LEA. Further studies are needed to explore strategies to prevent and monitor long-term LEA in these athletes. PMID:26131616

    This study focused on links between romantic attachment, positive body image, and sexual functioning. Dutch female university students (N = 399) completed an online survey that included self-report items about body appreciation, sexual functioning, and romantic attachment. A proposed conceptual model was tested using structural equation modeling and a good fit to the data was found. Results revealed that attachment avoidance in a romantic context was negatively related to sexual arousal, vaginal lubrication, the ability to reach orgasm, and sexual satisfaction. Attachment anxiety was negatively related to body appreciation which, in turn, was positively related to sexual desire and arousal. Findings indicated that romantic attachment is meaningfully linked to body appreciation and sexual functioning. Therefore, the concept of adult attachment may be a useful tool for the treatment of sexual problems of young women. PMID:25778405

    A new set of fluence-to-dose conversion coefficients based on the Chinese reference adult voxel phantoms CRAM and CRAF are presented for six idealized external neutron exposures from 10-8 MeV to 20 MeV. The voxel phantoms CRAM and CRAF were adjusted from the previous phantoms CNMAN and CNWM respectively, and the masses of individual organs have been adjusted to the Chinese reference data. The calculation of organ-absorbed doses and effective doses were performed with the Monte Carlo transport code MCNPX. The resulting dose conversion coefficients were compared with those published in ICRP Publication 116, which represents the reference Caucasian. The organ-absorbed dose conversion coefficients of most organs are in good agreement with the results in ICRP Publication 116, however, obvious discrepancies are observed for some organs and certain geometries. For neutrons with energies above 2 MeV, the effective dose conversion coefficients of Chinese reference adult are almost identical to those of ICRP Publicatio...

    The objective of this study was to investigate whether increased dietary water content and feeding frequency increased voluntary physical activity of young, lean adult female cats. A replicated 4 × 4 Latin square design with a 2 × 2 factorial treatment arrangement (feeding frequency and water content) was used. The 4 treatments consisted of 1 meal daily dry pet food without added water (1D; 12% moisture as is), 1 meal daily dry pet food with added water (1W; 70% total water content), 4 meals daily dry pet food without added water (4D; 12% moisture as is), and 4 meals daily dry pet food with added water (4W; 70% total water content). Eight healthy adult, lean, intact, young, female domestic shorthair cats were used in this experiment. Voluntary physical activity was evaluated using Actical activity monitors placed on collars and worn around the cats' necks for the last 7 d of each experimental period of 14 d. Food anticipatory activity (FAA) was calculated based on 2 h prior to feeding periods and expressed as a percentage of total daily voluntary physical activity. Increased feeding frequency (4 vs. 1 meal daily) resulted in greater average daily activity (P = 0.0147), activity during the light period (P = 0.0023), and light:dark activity ratio (P = 0.0002). In contrast, physical activity during the dark period was not altered by feeding frequency (P > 0.05). Cats fed 4 meals daily had increased afternoon FAA (P= 0.0029) compared with cats fed once daily. Dietary water content did not affect any measure of voluntary physical activity. Increased feeding frequency is an effective strategy to increase the voluntary physical activity of cats. Thus, it may assist in the prevention and management of obesity. PMID:26020354

    Background Physical inactivity is a growing health concern and has been identified as the fourth leading risk factor for global mortality. The Arab region includes countries with some of the world’s highest physical inactivity levels, such as Qatar, more specifically the Qatari female population. Objective The objective of this study is to assess the physical activity levels of Qatari national female adults during a 1-year pedometer-based program. Materials and methods A total of 549 Qatari national females aged between 18 years and 64 years were included. Data extracted from “Step into Health” program web database in Qatar were used for analyses. Daily habitual physical activity (daily total step count and aerobic steps) was assessed through the Omron HJ-324U pedometer. Step counts were classified as follows: <5,000 steps/d, sedentary; 5,000–7,499 steps/d, low active; and ≥7,500 steps/d, physically active. Statistical significance was set at P-value ≤0.05. Descriptive statistics were used, and habitual physical activity was calculated through repeated measures analysis of variance to determine the difference across the monitored days. Results Mean age was 37.4±11.7 years, and median body mass index of 28.8 kg/m2 (interquartile range 24.8–33.5). Daily steps for the overall population ranged from 3,505 steps/d to 10,010 steps/d, with a median of 6,008 steps/d. A total of 242 (44.1%) females were sedentary, 178 (32.4%) were low active, and 129 (23.5%) were physically active. The physically active group showed a median of 927 aerobic steps/d (interquartile range 0–4,248). Conclusion Based on the results of this study, Qatari females are not meeting the global recommendations of physical activity. Future research might need to consider barriers to physical activity as well as social, cultural, and environmental factors. PMID:27486343

    Female sexual function is a difficult entity to be assessed. Subjective factors and interview biases can change the perception of it. Using validated questionnaires can improve the scientific approach to this matter. There is a huge difference of severity and incidence among young, apparent healthy women, which are in a harmonious relationship. We evaluated 320 healthy women, with stable sexual active relationship, with no know depressive disease, endocrinological and metabolic pathology, no premature menopause, no malignancy. We compose a mathematic model to study the impact of age, and body weight on the sexual function, with FSFI total score as surrogate marker. We observed that even in healthy women, increase in age and/or weight/body mass significantly impair general sexual function.

    Wuzhishan miniature pig is one of the four most important pig breeds in China and has many major economic characteristics. Herein, we successfully used SCNT to clone Wuzhishan miniature pig. First, ear fibroblasts were isolated from a 2-year-old female Wuzhishan miniature piglet to be used as the donor cell. Second, good-quality COCs were selected from ovaries obtained from pigs at a local slaughterhouse and cultured. Mature eggs with the first polar body and ear fibroblasts were applied SCNT. Lastly, we in total produced 12 piglets with 7 piglets surviving to adults. Next, we used these pigs to test alloxan toxicity and to build T I D diabetes type. We know that diabetes mellitus is a chronic heterogeneous metabolic disease characterized by a high blood glucose level and abnormal insulin secretion. In this study, T I D (type I diabetes) was experimentally induced in cloned Wuzhishan miniature pigs with alloxan. In brief, an intravenous injection of alloxan (group B: 170 mg/kg, n = 3) was administered to pigs weighing between 27 and 39 kg. Sterile saline was administered to control pigs (n = 3). We determined the glycometabolism related index, performed an intravenous glucose tolerance test, and carried out immunohistochemistry experiments. There were no significant differences in body weight, blood glucose, and serum insulin in all groups, before treatment. The level of blood glucose was significantly higher (P pigs treated with 170 mg/kg alloxan. Immunolocalization studies showed a decrease in insulin reactivity in this treatment group as well. To conclude, our model holds promise in future studies of diabetes drug testing and islet xenotransplantation. PMID:26158462

    There is a growing interest in HIV infection and sexually transmitted infection (STI) disease burden and risk among transgender people globally; however, the majority of work has been conducted with male-to-female transgender populations. This research synthesis comprehensively reviews HIV and STI research in female-to-male (FTM) transgender adults. A paucity of research exists about HIV and STIs in FTMs. Only 25 peer-reviewed papers (18 quantitative, 7 qualitative) and 11 'grey literature' reports were identified, most in the US or Canada, that include data identifying HIV and STI risks in FTMs (five with fully laboratory-confirmed HIV and/or STIs, and five with partial laboratory confirmation). Little is known about the sexual and drug use risk behaviours contributing to HIV and STIs in FTMs. Future directions are suggested, including the need for routine surveillance and monitoring of HIV and STIs globally by transgender identity, more standardised sexual risk assessment measures, targeted data collection in lower- and middle-income countries, and explicit consideration of the rationale for inclusion/exclusion of FTMs in category-based prevention approaches with MSM and transgender people. Implications for research, policy, programming, and interventions are discussed, including the need to address diverse sexual identities, attractions, and behaviours and engage local FTM communities.

    A study was conducted to examine the effects of 25-hydroxyvitamin D3 (25-(OH)D3) on fecal Ca and P excretion, bone mineralization, performance and the mRNA expression of intestinal transporter genes in growing female pigs. Sixty-day old gilts (n = 24) with an average initial BW of 23.13 ± 1.49 kg were randomly allocated to a control diet (diet 1) containing wheat/corn/soybean meal and 150 IU kg(-1) of Vitamin D3, diet 1 + 50 μg of 25-(OH)D3 kg(-1) (diet 2) and diet 1 + 100 μg of 25-(OH)D3 kg(-1) (diet 3). The pigs were housed in an individual pen and had ad libitum access to feed and water for 42 days, and BWG and feed intake were measured weekly. Measures of bone mineralization and expression of Ca and P transporters mRNA were analyzed using Dual Energy X-Ray Absortiometry (DEXA) and quantitative real-time polymerase chain reaction (qRT-PCR), respectively. Data were analyzed using GLM procedure of the Statistical Analysis System (SAS Institute version 9.2). Fecal Ca and P concentration were significantly reduced (P ≤ 0.05) in pigs fed diets 2 and 3 compared with the control diet. Supplementation of 25-(OH)D3 did not significantly improve bone mineralization, animal performance and intestinal transporters mRNA expression except for SLC34A1, a sodium-dependent phosphate transporter 1. In conclusion, supplementation of 25-(OH)D3 in swine nutrition may not improve animal performance but has the potential to reduce environmental pollution by increasing dietary Ca and P retention while reducing their excretion.

    Full Text Available Steroid hormones have been implicated in the modulation of TSH secretion; however, there are few and controversial data regarding the effect of progesterone (Pg on TSH secretion. Medroxyprogesterone acetate (MPA is a synthetic alpha-hydroxyprogesterone analog that has been extensively employed in therapeutics for its Pg-like actions, but that also has some glucocorticoid and androgen activity. Both hormones have been shown to interfere with TSH secretion. The objective of the present study was to investigate the effects of MPA or Pg administration to ovariectomized (OVX rats on in vivo and in vitro TSH release and pituitary TSH content. The treatment of adult OVX rats with MPA (0.25 mg/100 g body weight, sc, daily for 9 days induced a significant (P<0.05 increase in the pituitary TSH content, which was not observed when the same treatment was used with a 10 times higher MPA dose or with Pg doses similar to those of MPA. Serum TSH was similar for all groups. MPA administered to OVX rats at the lower dose also had a stimulatory effect on the in vitro basal and TRH-induced TSH release. The in vitro basal and TRH-stimulated TSH release was not significantly affected by Pg treatment. Conversely, MPA had no effect on old OVX rats. However, in these old rats, ovariectomy alone significantly reduced (P<0.05 basal and TRH-stimulated TSH release in vitro, as well as pituitary TSH content. The results suggest that in adult, but not in old OVX rats, MPA but not Pg has a stimulatory effect on TSH stores and on the response to TRH in vitro.

    ICRP Publication 116 on ‘Conversion coefficients for radiological protection quantities for external radiation exposures’, provides fluence-to-dose conversion coefficients for organ-absorbed doses and effective dose for various types of external exposures (ICRP 2010 ICRP Publication 116). The publication supersedes the ICRP Publication 74 (ICRP 1996 ICRP Publication 74, ICRU 1998 ICRU Report 57), including new particle types and expanding the energy ranges considered. The coefficients were calculated using the ICRP/ICRU computational phantoms (ICRP 2009 ICRP Publication 110) representing the reference adult male and reference adult female (ICRP 2002 ICRP Publication 89), together with a variety of Monte Carlo codes simulating the radiation transport in the body. Idealized whole-body irradiation from unidirectional and rotational parallel beams as well as isotropic irradiation was considered for a large variety of incident radiations and energy ranges. Comparison of the effective doses with operational quantities revealed that the latter quantities continue to provide a good approximation of effective dose for photons, neutrons and electrons for the ‘conventional’ energy ranges considered previously (ICRP 1996, ICRU 1998), but not at the higher energies of ICRP Publication 116.

    The effects of hypothyroidism upon the structure of the central nervous system of adult rats are poorly understood in spite of evidence that the mature brain is vulnerable to this condition. Existing developmental studies show that the morphological changes induced by thyroid hormone deficiency are related to alterations in neurogenesis. We studied the granular layer of the dentate gyrus under different experimental conditions of hypothyroidism, because in rodents the neurogenesis of the granule cells continues during adulthood. The following groups of rats were analysed: 1) control; 2) hypothyroid from day 0 until day 180 (hypothyroid group); 3) hypothyroid until day 30 and henceforth maintained euthyroid (recovery group); and 4) hypothyroid since day 30 (adult hypothyroid group). Groups of 6 male rats and 6 female rats were analysed separately. The volume of the dentate gyrus granular layer and the numerical density of its neurons were evaluated, so we were able to estimate the total number of granule cells. Because in the experimental groups the volume of the granular layer and the numerical density of its neurons were reduced, the total number of granule cells was decreased. In the hypothyroid and recovery groups the alterations were identical and more striking than in the adult hypothyroid groups. The total number of granule cells displayed sexual differences in all groups studied except in the hypothyroid groups. The present results support the view that thyroid hormone deficiency interferes with the process of cell acquisition by reducing neuronal proliferation and that it also leads to increased cell death. These events underlie the irreversible morphological changes observed in the brain of hypothyroid rats, either during development or at maturity. The referred structural alterations are probably related to the functional deficits observed in this condition. PMID:1797872

  9. FASH and MASH: female and male adult human phantoms based on polygon mesh surfaces: II. Dosimetric calculations

    International Nuclear Information System (INIS)

    Female and male adult human phantoms, called FASH (Female Adult meSH) and MASH (Male Adult meSH), have been developed in the first part of this study using 3D animation software and anatomical atlases to replace the image-based FAX06 and the MAX06 voxel phantoms. 3D modelling methods allow for phantom development independent from medical images of patients, volunteers or cadavers. The second part of this study investigates the dosimetric implications for organ and tissue equivalent doses due to the anatomical differences between the new and the old phantoms. These differences are mainly caused by the supine position of human bodies during scanning in order to acquire digital images for voxel phantom development. Compared to an upright standing person, in image-based voxel phantoms organs are often coronally shifted towards the head and sometimes the sagittal diameter of the trunk is reduced by a gravitational change of the fat distribution. In addition, volumes of adipose and muscle tissue shielding internal organs are sometimes too small, because adaptation of organ volumes to ICRP-based organ masses often occurs at the expense of general soft tissues, such as adipose, muscle or unspecified soft tissue. These effects have dosimetric consequences, especially for partial body exposure, such as in x-ray diagnosis, but also for whole body external exposure and for internal exposure. Using the EGSnrc Monte Carlo code, internal and external exposure to photons and electrons has been simulated with both pairs of phantoms. The results show differences between organ and tissue equivalent doses for the upright standing FASH/MASH and the image-based supine FAX06/MAX06 phantoms of up to 80% for external exposure and up to 100% for internal exposure. Similar differences were found for external exposure between FASH/MASH and REGINA/REX, the reference voxel phantoms of the International Commission on Radiological Protection.

  10. Comparison of body fat in Brazilian adult females by bioelectrical impedance analysis

    International Nuclear Information System (INIS)

    Body-fat is essential for human body, provided that its amount is at healthy levels. If in-excess body-fat is deleterious, its lack is otherwise also harmful. Estimated percent body-fat performed with commercially available devices measuring bioimpedance have many advantages, such as easy measurement and low cost. However, these measurements are based on standard models and equations that are not disclosed by manufacturers, and this leads to questioning the validity of these estimates for Brazilian females. The aim of this study was to compare electrical tetrapolar and octapolar impedance results obtained with commercially available equipment: Maltron BF-906 and OMRON 510-W. Data analysis involved descriptive and inferential statistics. Devices used in this study to estimate body fat quantity have not shown any significant differences in results; this is a major issue when selecting equipment based on three factors: study focus, available financial resources, and target population. Results obtained from the two devices have not shown any significant differences, which lead to the conclusion that either device may be reliably used.

  12. Sex hormones affect neurotransmitters and shape the adult female brain during hormonal transition periods

    Full Text Available Sex hormones have been implicated in neurite outgrowth, synaptogenesis, dendritic branching, myelination and other important mechanisms of neural plasticity. Here we review the evidence from animal experiments and human studies reporting interactions between sex hormones and the dominant neurotransmitters, such as serotonin, dopamine, GABA and glutamate. We provide an overview of accumulating data during physiological and pathological conditions and discuss currently conceptualized theories on how sex hormones potentially trigger neuroplasticity changes through these four neurochemical systems. Many brain regions have been demonstrated to express high densities for estrogen- and progesterone receptors, such as the amygdala, the hypothalamus, and the hippocampus. As the hippocampus is of particular relevance in the context of mediating structural plasticity in the adult brain, we put particular emphasis on what evidence could be gathered thus far that links differences in behavior, neurochemical patterns and hippocampal structure to a changing hormonal environment. Finally, we discuss how physiologically occurring hormonal transition periods in humans can be used to model how changes in sex hormones influence functional connectivity, neurotransmission and brain structure in vivo.

  13. The Principal Components of Adult Female Insole Shape Align Closely with Two of Its Classic Indicators.

    Directory of Open Access Journals (Sweden)

    Fred L Bookstein

    Full Text Available The plantar surface of the human foot transmits the weight and dynamic force of the owner's lower limbs to the ground and the reaction forces back to the musculoskeletal system. Its anatomical variation is intensely studied in such fields as sports medicine and orthopedic dysmorphology. Yet, strangely, the shape of the insole that accommodates this surface and elastically buffers these forces is neither an aspect of the conventional anthropometrics of feet nor an informative label on the packet that markets supplementary insoles. In this paper we pursue an earlier suggestion that insole form in vertical view be quantified in terms of the shape of the foot not at the plane of support (the "footprint" but some two millimeters above that level. Using such sections extracted from laser scans of 158 feet of adult women from the University of Zagreb, in conjunction with an appropriate modification of today's standard geometric morphometrics (GMM, we find that the sectioned form can be described by its size together with two meaningful relative warps of shape. The pattern of this shape variation is not novel. It is closely aligned with two of the standard footprint measurements, the Chippaux-Šmiřák arch index and the Clarke arch angle, whose geometrical foci (the former in the ball of the foot, the latter in the arch it apparently combines. Thus a strong contemporary analysis complements but does not supplant the simpler anthropometric analyses of half a century ago, with implications for applied anthropology.

  14. First comparative transcriptomic analysis of wild adult male and female Lutzomyia longipalpis, vector of visceral leishmaniasis.

    Directory of Open Access Journals (Sweden)

    Christina B McCarthy

    Full Text Available Leishmaniasis is a vector-borne disease with a complex epidemiology and ecology. Visceral leishmaniasis (VL is its most severe clinical form as it results in death if not treated. In Latin America VL is caused by the protist parasite Leishmania infantum (syn. chagasi and transmitted by Lutzomyia longipalpis. This phlebotomine sand fly is only found in the New World, from Mexico to Argentina. However, due to deforestation, migration and urbanisation, among others, VL in Latin America is undergoing an evident geographic expansion as well as dramatic changes in its transmission patterns. In this context, the first VL outbreak was recently reported in Argentina, which has already caused 7 deaths and 83 reported cases. Insect vector transcriptomic analyses enable the identification of molecules involved in the insect's biology and vector-parasite interaction. Previous studies on laboratory reared Lu. longipalpis have provided a descriptive repertoire of gene expression in the whole insect, midgut, salivary gland and male reproductive organs. Nevertheless, the study of wild specimens would contribute a unique insight into the development of novel bioinsecticides. Given the recent VL outbreak in Argentina and the compelling need to develop appropriate control strategies, this study focused on wild male and female Lu. longipalpis from an Argentine endemic (Posadas, Misiones and a Brazilian non-endemic (Lapinha Cave, Minas Gerais VL location. In this study, total RNA was extracted from the sand flies, submitted to sequence independent amplification and high-throughput pyrosequencing. This is the first time an unbiased and comprehensive transcriptomic approach has been used to analyse an infectious disease vector in its natural environment. Transcripts identified in the sand flies showed characteristic profiles which correlated with the environment of origin and with taxa previously identified in these same specimens. Among these, various genes

    The aim of this work was to modify the standing posture of the anthropomorphic reference phantoms of ICRP publication 110, AM (Adult Male) and AF (Adult Female), to the sitting posture. The change of posture was performed using the Visual Monte Carlo software (VMC) to rotate the thigh region of the phantoms and position it between the region of the leg and trunk. Scion Image software was used to reconstruct and smooth the knee and hip contours of the phantoms in a sitting posture. For 3D visualization of phantoms, the VolView software was used. In the change of postures, the organ and tissue masses were preserved. The MCNPX was used to calculate the equivalent and effective dose conversion coefficients (CCs) per fluence for photons for six irradiation geometries suggested by ICRP publication 110 (AP, PA, RLAT, LLAT, ROT and ISO) and energy range 0.010-10 MeV. The results were compared between the standing and sitting postures, for both sexes, in order to evaluate the differences of scattering and absorption of radiation for different postures. Significant differences in the CCs for equivalent dose were observed in the gonads, colon, prostate, urinary bladder and uterus, which are present in the pelvic region, and in organs distributed throughout the body, such as the lymphatic nodes, muscle, skeleton and skin, for the phantoms of both sexes. CCs for effective dose showed significant differences of up to 16% in the AP irradiation geometry, 27% in the PA irradiation geometry and 13% in the ROT irradiation geometry. These results demonstrate the importance of using phantoms in different postures in order to obtain more precise conversion coefficients for a given exposure scenario.

    Pregnancy and parturition can dramatically affect female neurobiology and behavior. This is especially true for laboratory-reared rodents, in part, because such rearing prevents a host of developmental experiences that females might undergo in nature, including juvenile alloparenting. We examined the effect of chronic exposure to pups during post-weaning juvenile life (days 22-36) on adult maternal responsiveness, anxiety-related behaviors, and dorsal raphe tryptophan hydroxylase-2 (TPH2) and serotonin transporter (SERT) levels in nulliparous rats. Adult females with juvenile alloparental experience showed significantly faster sensitized maternal responsiveness, less anxiety, and more dorsal raphe TPH2. Juvenile alloparenting did not affect females' later social novelty and preference behaviors toward adults, suggesting their increased interest in pups did not extend to all social partners. In a second experiment, suckling a pregnant dam (achieved by postpartum estrus reinsemination), interacting with her after standard laboratory weaning age, and a 3-day exposure to younger siblings also reduced juvenile females' later anxiety but did not affect maternal responsiveness or TPH2. Thus, extensive juvenile "babysitting" can have long-term effects reminiscent of pregnancy and parturition on maternal responsiveness and anxiety, and these effects may be driven by upregulated serotonin. © 2016 Wiley Periodicals, Inc.

    This case study focused on a pig production system in a rural area of North Central Vietnam, with a focus on describing household pig breeding practices and estimating herd demographic parameters, particularly on reproduction. One hundred five households undertaking small-scale piglet production were surveyed, with information gathered on 3268 individual pigs. Pig keeping contributed variably to the overall household livelihood portfolio, with female household members as the main decision makers, contributors to labor, and beneficiaries of income from the pig enterprise. All households kept between one and four young or adult sows, with 69% of these sows of a local breed type (predominantly Mong Cai), 28% a cross between a local sow and an exotic sow (predominantly Large White), and the remainder (3%) as exotic sows. Eighty-eight percent of the piglets produced were cross-bred, while 12% were local breed. No adult males were kept by the surveyed households, reflecting the common use of artificial insemination for mating purposes. The most common breeding system practiced-the keeping of Mong Cai females and production of cross-bred piglets-capitalizes on the small body size and high fecundity of the sows and the fast growth rate and leanness of the cross-bred piglets. The survey tool used, which was based on farmer recall of events over the preceding 12-month period, appeared to give reasonable results although some recall bias could be detected. This case study will serve as an entry point to planned broader scale characterization and development of pig breeding systems in North Central Vietnam. PMID:25947237

    Full Text Available Abstract Background Stress during fetal life increases the risk of affective and immune disorders later in life. The altered peripheral immune response caused by prenatal stress may impact on brain function by the modification of local inflammation. In this study we have explored whether prenatal stress results in alterations in the immune response in the hippocampus of female mice during adult life. Methods Pregnant C57BL/6 mice were subjected three times/day during 45 minutes to restraint stress from gestational Day 12 to delivery. Control non-stressed pregnant mice remained undisturbed. At four months of age, non-stressed and prenatally stressed females were ovariectomized. Fifteen days after surgery, mice received an i.p. injection of vehicle or of 5 mg/kg of lipopolysaccharide (LPS. Mice were sacrificed 20 hours later by decapitation and the brains were removed. Levels of interleukin-1β (IL1β, interleukin-6 (IL-6, tumor necrosis factor α (TNF-α, interferon γ-inducible protein 10 (IP10, and toll-like receptor 4 mRNA were assessed in the hippocampus by quantitative real-time polymerase chain reaction. Iba1 immunoreactivity was assessed by immunocytochemistry. Statistical significance was determined by one-way or two-way analysis of variance. Results Prenatal stress, per se, increased IL1β mRNA levels in the hippocampus, increased the total number of Iba1-immunoreactive microglial cells and increased the proportion of microglial cells with large somas and retracted cellular processes. In addition, prenatally stressed and non-stressed animals showed different responses to peripheral inflammation induced by systemic administration of LPS. LPS induced a significant increase in mRNA levels of IL-6, TNF-α and IP10 in the hippocampus of prenatally stressed mice but not of non-stressed animals. In addition, after LPS treatment, prenatally stressed animals showed a higher proportion of Iba1-immunoreactive cells in the hippocampus with

    Intrauterine growth restriction (IUGR) is a risk factor for memory impairment and emotional disturbance during growth and adulthood. However, this risk might be modulated by environmental factors during development. Here we examined whether exposing adolescent male and female rats with thromboxane A2-induced IUGR to social defeat stress (SDS) affected their working memory and anxiety-like behavior in adulthood. We also used BrdU staining to investigate hippocampal cellular proliferation and BrdU and NeuN double staining to investigate neural differentiation in female IUGR rats. In the absence of adolescent stress, IUGR female rats, but not male rats, scored significantly lower in the T-maze test of working memory and exhibited higher anxiety-like behavior in the elevated-plus maze test compared with controls. Adolescent exposure to SDS abolished these behavioral impairments in IUGR females. In the absence of adolescent stress, hippocampal cellular proliferation was significantly higher in IUGR females than in non-IUGR female controls and was not influenced by adolescent exposure to SDS. Hippocampal neural differentiation was equivalent in non-stressed control and IUGR females. Neural differentiation was significantly increased by adolescent exposure to SDS in controls but not in IUGR females. There was no significant difference in the serum corticosterone concentrations between non-stressed control and IUGR females; however, adolescent exposure to SDS significantly increased serum corticosterone concentration in control females but not in IUGR females. These results demonstrate that adolescent exposure to SDS improves behavioral impairment independent of hippocampal neurogenesis in adult rats with IUGR. PMID:25725425

    Full Text Available Background: The objectives of this study were to examine (a the prevalence of overweight/obesity, and (b the relationship between body mass index (BMI, body fat percentage (BF and physical fitness in adolescent and adult female volleyball players. Materials and Methods: Adolescent (n = 102, aged 15.2 ± 2.0 year and adult (n = 57, 25.9 ± 5.0 year players were examined for anthropometric characteristics and body composition, and performed the physical working capacity in heart rate 170 min -1 test, a force-velocity test, the Wingate anaerobic test (WAnT, sit-and-reach test (SAR, handgrip strength test (HST and countermovement vertical jump (CVJ. Results: Based on international BMI cut-off points, 27.5% (n = 28 of adolescent and 12.3% (n = 7 of adult participants were classified as overweight, with the prevalence of overweight being higher in girls than in women (χ2 = 4.90, P = 0.027. BMI was correlated with BF in both age groups (r = 0.72, P < 0.001 in girls; r = 0.75, P < 0.001 in women. Normal participants had superior certain physical and physiological characteristics than those who were overweight. For instance, normal girls and women had higher mean power during WAnT than their overweight counterparts (P = 0.003 and P = 0.009 respectively. Except for flexibility, BMI and BF were inversely related with physical fitness (e.g., BMI vs. HST r = -0.39, P < 0.001 in girls; BF vs. CVJ r = -0.45, P < 0.001 in women. Conclusion: The findings confirmed the negative effect of overweight and fatness on selected parameters of physical fitness. The prevalence of overweight in adolescent volleyball players was higher than in general population, which was a novel finding, suggesting that proper exercise interventions should be developed to target the excess of body mass in youth volleyball clubs.

    Does the posture of a patient have an effect on the organ and tissue absorbed doses caused by x-ray examinations? This study aims to find the answer to this question, based on Monte Carlo (MC) simulations of commonly performed x-ray examinations using adult phantoms modelled to represent humans in standing as well as in the supine posture. The recently published FASH (female adult mesh) and MASH (male adult mesh) phantoms have the standing posture. In a first step, both phantoms were updated with respect to their anatomy: glandular tissue was separated from adipose tissue in the breasts, visceral fat was separated from subcutaneous fat, cartilage was segmented in ears, nose and around the thyroid, and the mass of the right lung is now 15% greater than the left lung. The updated versions are called FASH2_sta and MASH2_sta (sta = standing). Taking into account the gravitational effects on organ position and fat distribution, supine versions of the FASH2 and the MASH2 phantoms have been developed in this study and called FASH2_sup and MASH2_sup. MC simulations of external whole-body exposure to monoenergetic photons and partial-body exposure to x-rays have been made with the standing and supine FASH2 and MASH2 phantoms. For external whole-body exposure for AP and PA projection with photon energies above 30 keV, the effective dose did not change by more than 5% when the posture changed from standing to supine or vice versa. Apart from that, the supine posture is quite rare in occupational radiation protection from whole-body exposure. However, in the x-ray diagnosis supine posture is frequently used for patients submitted to examinations. Changes of organ absorbed doses up to 60% were found for simulations of chest and abdomen radiographs if the posture changed from standing to supine or vice versa. A further increase of differences between posture-specific organ and tissue absorbed doses with increasing whole-body mass is to be expected.

In a first step, both phantoms were updated with respect to their anatomy: glandular tissue was separated from adipose tissue in the breasts, visceral fat was separated from subcutaneous fat, cartilage was segmented in ears, nose and around the thyroid, and the mass of the right lung is now 15% greater than the left lung. The updated versions are called FASH2sta and MASH2sta (sta = standing). Taking into account the gravitational effects on organ position and fat distribution, supine versions of the FASH2 and the MASH2 phantoms have been developed in this study and called FASH2sup and MASH2sup. MC simulations of external whole-body exposure to monoenergetic photons and partial-body exposure to x-rays have been made with the standing and supine FASH2 and MASH2 phantoms. For external whole-body exposure for AP and PA projection with photon energies above 30 keV, the effective dose did not change by more than 5% when the posture changed from standing to supine or vice versa. Apart from that, the supine posture is quite rare in occupational radiation protection from whole-body exposure. However, in the x-ray diagnosis supine posture is frequently used for patients submitted to examinations. Changes of organ absorbed doses up to 60% were found for simulations of chest and abdomen radiographs if the posture changed from standing to supine or vice versa. A further increase of differences between posture-specific organ and tissue absorbed doses with increasing whole-body mass is to be expected.

  6. A Pilot Study of Uterine Artery Embolization with Tris-Acryl Gelatin Microspheres in Guinea Pigs

    International Nuclear Information System (INIS)

    Objective: This study was designed to establish guinea pigs as an animal model for uterine artery embolization (UAE) with tris-acryl gelatin microspheres (TAGM). Methods: Twenty-five female adult guinea pigs were randomly divided into two groups, including a uterine artery casting mould group (n = 10) and a UAE group (n = 15). Pelvic angiography and vascular casting mould were performed in the first group. The anatomical characters of the pelvic cavity in guinea pigs were described. In the second group, the technical feasibility of performing UAE with TAGM in guinea pigs was investigated. The histopathological slides of the uterus of guinea pigs after UAE were examined to inspect the outcomes of UAE. Results: The uterine artery springs from the internal iliac artery, ascends tortuously along the cervix, and gives off vertically 8–10 branches to the cervix uteri and uterine horns. The diameters of the trunk of the uterine artery and its first branch were 0.32 ± 0.027 mm and 0.14 ± 0.01 mm, respectively. For UAE animals, the dosages of 40–120 and 100–300 μm TAGM were 0.033 ± 0.003 ml and 0.015 ± 0.002 ml, respectively. On histopathological slides, embosphere particles were found in the first branches of the uterine artery, the subserous arteries, and the intramural arteries. Inflammatory reactions in the uterus were common in guinea pigs after UAE. Local or dispersed areas of necrosis in uterus also were observed in a few guinea pigs. Conclusions: Guinea pigs are an appropriate and feasible model for UAE with TAGM.

    The use of a microfilaricidal drug for the control of onchocerciasis and lymphatic filariasis necessitates prolonged yearly dosing. Prospects for elimination or eradication of these diseases would be enhanced by availability of a macrofilaricidal drug. Flubendazole (FLBZ), a benzimidazole anthelmintic, is an appealing candidate macrofilaricide. FLBZ has demonstrated profound and potent macrofilaricidal effects in a number of experimental filarial rodent models and one human trial. Unfortunately, FLBZ was deemed unsatisfactory for use in mass drug administration (MDA) campaigns due to its markedly limited oral bioavailability. However, a new formulation that provided sufficient bioavailability following oral administration could render FLBZ an effective treatment for onchocerciasis and LF. This study characterized the effects of FLBZ and its reduced metabolite (FLBZ-R) on filarial nematodes in vitro to determine the exposure profile which results in demonstrable damage. Adult female Brugia malayi were exposed to varying concentrations of FLBZ or FLBZ-R (100 nM-10 μM) for up to five days, after which worms were fixed for histology. Morphological damage following exposure to FLBZ was observed prominently in the hypodermis and developing embryos at concentrations as low as 100 nM following 24 h exposure. The results indicate that damage to tissues required for reproduction and survival can be achieved at pharmacologically relevant concentrations. PMID:26288741

    Full Text Available Objective: To investigate the short-term effects of ormeloxifene on systemic hemodynamics, coagulation profile, and serum antioxidant activity in vivo in comparison with raloxifene. Materials and Methods: Colony-bred adult female Sprague-Dawley rats were randomized into 19 groups of 10 each and received either ormeloxifene or raloxifene (0.25, 1.25, or 3 mg/kg/day for 7, 15, or 30 days by the oral route. Animals of control group received vehicle (gum-acacia in distilled water alone in a similar manner. Systemic hemodynamics and serum total antioxidant activity were assessed 24 h after the last treatment. Results: There was no significant effect of ormeloxifene administered at these doses and schedules on hemodynamic parameters or antioxidant activity, except for increase in amplitude of R wave in rats treated with 3 mg/kg/day dose for 30 days. This effect with raloxifene was evident only 7 days after treatment at this dose. Overall response was, however, almost similar with both the agents. Conclusion: The findings demonstrate comparable pharmacological profile of ormeloxifene and raloxifene on short-term administration to rats. Based on changes observed in the ECG (R wave, long-term studies may lead to justifiable comparison of beneficial and harmful effects of ormeloxifene and raloxifene in relation to cardiovascular effects.

    Effects of maize (Zea mays L.) volatiles induced by larvae of the Asian corn borer, Ostrinia furnacalis (Guenee), on the orientation behaviors of Asian corn borer larvae and oviposition of the females were investigated. Nineteen volatile chemicals, with terpenes being the major components, were identified from maize plants attacked by third instar Asian corn borer larvae. Coupled gas chromatographic-electroantennographic detection (GC-EAD) analyses revealed some electroantennographic differences between female and male Asian corn borer antennae in response to larvae-induced maize volatiles; female responded to (E)-2-hexenal, nonanal, (Z)-3-hexen-1-ol and three unknown compounds while the male only responded to (E)-2-hexenal, nonanal and one unknown compound. In laboratory orientation bioassays, Asian corn borer neonate larvae were attracted to extracts collected from Asian corn borer-damaged plants as well as to synthetic famesene, but were repelled by (Z)-3-hexen- 1-ol. In laboratory oviposition bioassays, gravid females laid fewer eggs on plants damaged by larvae than on mechanically damaged plants or undamaged plants. Adult Asian corn borer females deposited fewer eggs on wax paper treated with (E)-2-hexenal or (Z)-3-hexen-l-ol than on wax paper treated with hexane (control). The results suggest that Asian corn borer can affect the behaviors of conspecific larvae and adults by changing host plant volatiles.

  14. Faecal and urinary excretion of 14C-steroids in sheep and pigs

    International Nuclear Information System (INIS)

    Adult sheep and pigs were infused intravenously 14C-steroid hormones (0.1 mCi) dissolved in 0.9% NaCl/ 10% ethanol over a period of 4 hours: progesterone (3 females), oestrone (3 female sheep, 2 sows and 2 boars), testosterone (3 males) and cortisol (2 females and 2 males). Faeces were collected from all animals and urine from the male ones after spontaneous voidance, whereas in females urine was sampled via catheter. An extraction procedure, which allowed a good recovery of radioactivity in faecal samples of all 4 different steroid infusions was established. In sheep oestrone and progesterone were eliminated preferentially via faeces (88 ± 9 % and 76 ± 5 % of the recovered radioactivity), whereas cortisol and testosterone were excreted mainly via urine (72 ± 5 % und 58 ± 4 %). In pigs the main route of excretion for all hormones was the urine (oestrone: 97 ± 1 %, cortisol: 93 ± 3 % , testosterone: 83 ± 2 % and progesterone 67 ± 2 %). In urine the maximal concentration of all hormones was observed during or immediately after the infusion, in the faeces of sheep 6.5 to 20 hours and in the faeces of pigs 21 to 112 hours later

    Adult male and female rats were treated with the peptide nootrope drug noopept (daily dose, 0.1 mg/kg) and piracetam (200 mg/kg). In the period from 8th to 20th day, both drugs (cognitive enhancers) suppressed the horizontal and vertical activity and the anxiety in test animals as compared to the control group treated with 0.9 % aqueous NaCl solution. Early postnatal injections of the nootropes influenced neither the morphology development nor the behavior of adult female rats in the plus maze, extrapolational escape, passive avoidance, and pain sensitivity threshold tests. Animals in the "intact" group (having received neither drugs not physiological solution, that is, developing in a poor sensor environment), showed less pronounced habituation in the open field test as compared to the control and drug treated groups.

    This study investigates the interobserver and intraobserver reliability of qualitative behavior assessments (QBA) of individual pigs by 3 observer groups selected for their diverging backgrounds, experience, and views of pigs. Qualitative behavior assessment is a "whole animal" assessment approach that characterizes the demeanor of an animal as an expressive body language, using descriptors such as relaxed, anxious, or content. This paper addresses the concern that use of such descriptors in animal science may be prone to distortion by observer-related bias. Using a free-choice profiling methodology, 12 pig farmers, 10 large animal veterinarians, and 10 animal protectionists were instructed to describe and score the behavioral expressions of 10 individual pigs (sus scrofa) in 2 repeat sets of 10 video clips, showing these pigs in interaction with a human female. They were also asked to fill in a questionnaire gauging their experiences with and views on pigs. Pig scores were analyzed with generalized procrustes analysis and effect of treatment on these scores with ANOVA. Questionnaire scores were analyzed with a χ(2) test or ANOVA. Observers achieved consensus both within and among observer groups (P 0.90). The 3 groups also repeated their assessments of individual pigs with high precision (r > 0.85). Animal protectionists used a wider quantitative range in scoring individual pigs on dimension 2 than the other groups (P empathy for pigs (P reliability in their characterizations of pig body language. This supports the empirical nature of QBA in context of the wider anthropomorphism debate. PMID:22745187

    Full Text Available Abstract Background Allergic sensitization and reactions to guinea pig (Cavia porcellus have been well documented in laboratory animal handlers, primarily manifesting as rhinitis, conjunctivitis, and asthma. Severe allergic reactions, however, are rare. Methods We report two patients with severe allergic reactions following non-occupational exposure to guinea pigs. The first patient, an 11-year-old female, developed ocular, nasal, skin and laryngeal edema symptoms immediately after handling a guinea pig. The second patient, a 24-year-old female, developed symptoms of isolated laryngeal edema after cleaning a guinea pig cage. Percutaneous skin testing, RAST, ELISA and ELISA inhibition testing with guinea pig extract were performed. Results Both patients had IgE-mediated allergy to guinea pig confirmed by ELISA and either RAST or skin testing. ELISA inhibition studies confirmed the specificity of the IgE reactivity to guinea pig. Conclusion Severe IgE-mediated reactions can occur following non-occupational guinea pig exposure. Physicians should be aware of this possibility.

  8. Shaking Youngsters and Shaken Adults: Female Beetles Eavesdrop on Larval Seed Vibrations to Make Egg-Laying Decisions.

    Directory of Open Access Journals (Sweden)

    Raul Narciso C Guedes

    Full Text Available Egg-laying decisions are critical for insects, and particularly those competing for limited resources. Sensory information used by females to mediate egg-laying decisions has been reported to be primarily chemical, but the role of vibration has received little attention. We tested the hypothesis that vibrational cues produced by feeding larvae occupying a seed influences egg-laying decisions amongst female cowpea beetles. This hypothesis is supported by three lines of evidence using two strains of the cowpea beetle (Callosobruchus maculatus, an Indian strain with choosy females and aggressively competing larvae and a Brazilian strain with less choosy females and larvae exhibiting an "accommodating" type of competition. First, in free-choice bioassays of seed selection, choosy Indian females selected control seeds (free of eggs, larvae, or egg-laying marker over seeds with live larvae (free of eggs and egg-laying marker, but did not discriminate between control seeds and those with dead larvae. In contrast, less choosy Brazilian females showed no preference for seeds containing live or dead larvae over controls. Second, laser-doppler vibrometer recordings confirmed that larvae feeding inside seeds generate vibrations that are available to the female during egg-laying decisions. Third, during dichotomous choice experiments where artificial vibrations approximating those produced by feeding larvae were played back during seed selection, Indian females preferred immobile control seeds over vibrating seeds, but Brazilian females showed no preference. These results support the hypothesis that females use larval vibrations in their egg-laying decisions; whether these vibrations are passive cues exploited by the female, or active signals that 'steer' the behaviour of the female is unknown. We propose that vibration cues and signals could be important for host selection in insects, particularly those laying on substrates where visual or chemical cues may

    The pubertal surge in gonadal hormones that occurs during adolescence may impact the long-term effects of early alcohol exposure and sex differences in drinking behavior in adulthood. We investigated this hypothesis by performing sham or gonadectomy surgeries in Long Evans rats around postnatal day (P) 20. From P35–45, males and females were given saline or 3.0 g/kg ethanol using a binge-like model of exposure (8 injections total). As adults (P100), they were trained to self-administer ethanol via a sucrose-fading procedure and then given access to different unsweetened concentrations (5–20% w/v) for 5 days/concentration. We found that during adolescence, ethanol-induced intoxication was similar in males and females that underwent sham surgery. In gonadectomized males and females, however, the level of intoxication was greater following the last injection compared to the first. During adulthood, females drank more sucrose per body weight than males and binge-like exposure to ethanol reduced sucrose consumption in both sexes. These effects were not seen in gonadectomized rats. Ethanol consumption was higher in saline-exposed females compared to males, with gonadectomy reversing this sex difference by increasing consumption in males and decreasing it in females. Exposure to ethanol during adolescence augmented ethanol consumption in both sexes, but this effect was statistically significant only in gonadectomized females. Together, these results support a role for gonadal hormones during puberty in the short- and long-term effects of ethanol on behavior and in the development of sex differences in consummatory behavior during adulthood.

    2013-01-01

    The gonadal steroids, in particular estradiol, exert an important action during perinatal period in the regulation of sexual dimorphism and neuronal plasticity, and in the growth and development of nervous system. Exposure of the developing female to estrogens during perinatal period may have long-lasting effects that are now regarded as “programming” the female neuroendocrine axis to malfunction in adulthood. The purpose of this study was to describe the effect of a single administration of ...

  18. Fortuitous encounters between seagliders and adult female northern fur seals (Callorhinus ursinus off the Washington (USA coast: upper ocean variability and links to top predator behavior.

    Directory of Open Access Journals (Sweden)

    Noel A Pelland

    Full Text Available Behavioral responses by top marine predators to oceanographic features such as eddies, river plumes, storms, and coastal topography suggest that biophysical interactions in these zones affect predators' prey, foraging behaviors, and potentially fitness. However, examining these pathways is challenged by the obstacles inherent in obtaining simultaneous observations of surface and subsurface environmental fields and predator behavior. In this study, migratory movements and, in some cases, diving behavior of 40 adult female northern fur seals (NFS; Callorhinus ursinus were quantified across their range and compared to remotely-sensed environmental data in the Gulf of Alaska and California Current ecosystems, with a particular focus off the coast of Washington State (USA--a known foraging ground for adult female NFS and where autonomous glider sampling allowed opportunistic comparison of seal behavior to subsurface biophysical measurements. The results show that in these ecosystems, adult female habitat utilization was concentrated near prominent coastal topographic, riverine, or inlet features and within 200 km of the continental shelf break. Seal dive depths, in most ecosystems, were moderated by surface light level (solar or lunar, mirroring known behaviors of diel vertically-migrating prey. However, seal dives differed in the California Current ecosystem due to a shift to more daytime diving concentrated at or below the surface mixed layer base. Seal movement models indicate behavioral responses to season, ecosystem, and surface wind speeds; individuals also responded to mesoscale eddies, jets, and the Columbia River plume. Foraging within small scale surface features is consistent with utilization of the inner coastal transition zone and habitats near coastal capes, which are known eddy and filament generation sites. These results contribute to our knowledge of NFS migratory patterns by demonstrating surface and subsurface behavioral responses

    Several studies have reported an increase in the prevalence of adult female acne. This subtype of acne presents particular characteristics, and can be triggered by several factors such as smoking, stress, the use of oily cosmetics and even by poor sleep. Sleep quality is related to well-being and the maintenance of body homeostasis. In addition, several skin diseases present a bidirectional relationship with sleep, demonstrating an important connection between skin and the central nervous system. With this in mind, we aimed to compare the effect of two types of treatment for adult female acne (azelaic acid or a combined oral contraceptive) on sleep quality and on concentrations of stress hormones. Also, we proposed to assess the correlation of sleep and hormonal parameters with acne severity. In order to do this, 32 women underwent a clinical evaluation, completed the Pittsburgh Sleep Quality Index (PSQI) questionnaire and had their blood collected for hormone assays. These procedures were performed at baseline and after 6 months of treatment. At baseline there were no differences between the groups in terms of body mass index, age, acne severity and hormone concentrations. Results showed that both treatments demonstrated effectiveness but that women treated with azelaic acid presented a better sleep quality after the treatment compared to baseline and to the group treated with the combined oral contraceptive. The combined oral contraceptive group presented an increase in cortisol and a decrease in free testosterone concentration in relation to baseline. These data suggest that both azelaic acid and combined oral contraceptive are effective in the treatment of adult female acne but, azelaic acid seems to be a more suitable option for those women who may benefit from a better subjective sleep quality.

    The pubertal surge in gonadal hormones that occurs during adolescence may impact the long-term effects of early alcohol exposure and sex differences in drinking behavior in adulthood. We investigated this hypothesis by performing sham or gonadectomy surgeries in Long Evans rats around postnatal day (P) 20. From P35–45, males and females were given saline or 3.0 g/kg ethanol using a binge-like model of exposure (8 injections total). As adults (P100), they were trained to self-administer ethano...

    The functional significance of allometric change in reptiles has received limited attention and the reason for such changes has been regarded as 'obscure'. In this paper we report data on the Australian Pogona barbata, the eastern bearded dragon, from across their range and review changes in allometric growth among juveniles, and adult males and females and consider the functional relevance of these changes. There were significant differences in the population for mass, tail length, tail width, rear leg length and jaw length. These differences were consistent with differences required in locomotor performance and thus habitat use, together with access to different preferred dietary components. PMID:21236651

    The new concept of mammalian sex maintenance establishes that particular key genes must remain active in the differentiated gonads to avoid genetic sex reprogramming, as described in adult ovaries after Foxl2 ablation. Dmrt1 plays a similar role in postnatal testes, but the mechanism of adult testis maintenance remains mostly unknown. Sox9 and Sox8 are required for postnatal male fertility, but their role in the adult testis has not been investigated. Here we show that after ablation of Sox9 in Sertoli cells of adult, fertile Sox8(-/-) mice, testis-to-ovary genetic reprogramming occurs and Sertoli cells transdifferentiate into granulosa-like cells. The process of testis regression culminates in complete degeneration of the seminiferous tubules, which become acellular, empty spaces among the extant Leydig cells. DMRT1 protein only remains in non-mutant cells, showing that SOX9/8 maintain Dmrt1 expression in the adult testis. Also, Sox9/8 warrant testis integrity by controlling the expression of structural proteins and protecting Sertoli cells from early apoptosis. Concluding, this study shows that, in addition to its crucial role in testis development, Sox9, together with Sox8 and coordinately with Dmrt1, also controls adult testis maintenance. PMID:27328324

    Females of Osmia rufa, as most species in this genus, enter an obligatory diapause, overwintering as an imago inside a cocoon until the ensuing spring when after emergence - mating, egg development and oviposition occur. Diapause in this species is initiated in November, undergoes 2 months of a pre-wintering period that is terminated at the end of January, after 1 month of maintenance. In this study, factors that affect the termination of adult diapause in the female of this species were investigated. The experimental material consisted of bees that were brought from nests kept in natural conditions 1 month prior to natural termination of diapause. Three different experimental treatments were planned to evaluate the potential effect of methoprene and temperature on diapause termination. During the 5 day experimental period the first group of females was kept at 4°C, the second group at 15°C and the last group of females was kept at 20°C. All groups of females were treated with methoprene topically at a dose of 200 μg. After methoprene application a significant increase (p<0.001) in the size of terminal oocytes was recorded in the three experimental groups. However, no changes in the size of terminal oocytes between acetone treated and untreated control groups were observed. The number of oocytes progressively increased following topical application of methoprene compared to non-treated or acetone treated females. In successive applications of 200 μg methoprene gradual changes in ovary and fat body protein concentration were observed. As compared to controls, protein content in ovaries isolated from methoprene-treated females increased, whereas it decreased in fat body. The least differences in oocyte size and protein concentration in ovary and fat body between control groups and with methoprene application occurred at 4°C. Differences increased and were higher in females kept at 20°C and increased rapidly after methoprene application. Exposure to increasing

    We studied the effect of a new nootropic dipeptide Noopept and reference nootropic preparation piracetam injected subcutaneously on days 8-20 of life on learning of alternative feeding response in a 6-arm-maze in male and female rats. Early postnatal administration of Noopept disturbed the dynamics of learning by parameters of declarative and procedural memory. Piracetam impaired learning by parameters of procedural, but not declarative memory (only in males). Both preparations decreased the ratio of successfully learned males (but not females). The observed effects were not associated with changes in locomotor activity. PMID:16224581

    Consuming an unhealthy level of alcohol is a significant problem for some young women. Potential determinants of excess consumption include perceptions of usual consumption among peers-perceptions of what is "normal." The present study examined whether perceptions of social normative endorsement of drinking, operationalized by measures of perceived alcohol consumption of close friends (proximal norms), the consumption of the "average student" (distal norms), and the extent of alcohol-related content posted by peers on Facebook were related to alcohol-related attitudes and self-reported consumption. Female university students (n=129; Mage=21.48 years, SD=3.00) completed an online questionnaire assessing Facebook use, perceived alcohol-related norms, and self-reported alcohol attitudes and consumption. Perceptions of the consumption of the average female student were a negative predictor of attitudes. Positive alcohol attitudes, extent of own alcohol-related photographic posts on Facebook, average female student alcohol consumption, and report of male close friend consumption predicted self-report of own alcohol consumption. Interestingly, female close friend norms failed to predict consumption, whereas male close friend norms predicted consumption but not attitudes, suggesting the possibility of separate cognitive pathways for alcohol-related attitudes and behavior. This study builds on existing research by casting new light on predictors of alcohol-related attitudes, as well as describing the potential role of social networking sites such as Facebook in the formation of social norms and the modulation of drinking behavior.

    Full Text Available The present cross-sectional study was carried out to find the association of percent body fat (PBF with blood pressure (BP variables among apparently healthy young females studying in Guru Nanak Dev University, Amritsar. A total of 150 females ranging in age from 20-25 years were personally interviewed. Height and weight of each subject was taken using standard methodology. Their body composition parameters were taken by using body fat analyzer. Subjects were categorized as obese and non-obese according to PBF, in which those having >30% body fat was considered as obese. BP of each subject was measured by using the standard methodology. The prevalence of hypertension was calculated according to JNC VII criteria. In the pooled data, the percentage prevalence of obesity according to PBF was 36%. The percentage prevalence of pre-hypertension and hypertension in the pooled sample was 54% and 12%, respectively. However, it was observed that prevalence of hypertension was slightly more among obese females (7.3% as compared to non-obese (4.7% but the prevalence of pre-hypertension was significantly (p<0.05 more in non-obese females (39.3% as compared to obese females (14.7%. The underline cause of this high prevalence of pre-hypertension in non-obese subjects was not known. It is clear from the correlation analysis that no association was observed between SBP and MAP with PBF in obese and non-obese subjects while DBP is positively and significantly (p<0.05 correlated with weight, fat mass and fat free mass in non-obese subjects only. Thus it is concluded from this study that PBF measured by BIA was not likely to be a good predictor of high BP. Therefore, further large prospective studies on the association of hypertension and whole body fat and abdominal fat should be carried out to confirm the role of fat on BP.

    Human adolescents often consume alcohol in a binge-like manner at a time when changes are occurring within specific brain structures, such as the medial prefrontal cortex (mPFC) and the basolateral nucleus of the amygdala (BLN). In particular, the number of neurons and glia is changing in both of these areas in the rat between adolescence and adulthood (Markham et al., 2007; Rubinow and Juraska, 2009). The current study investigated the effects of ethanol exposure during adolescence on the number of neurons and glia in the adult mPFC and BLN in Long-Evans male and female rats. Saline or 3g/kg ethanol was administered between postnatal days (P) 35-45 in a binge-like pattern, with 2days of injections followed by 1 day without an injection. Stereological analyses of the ventral mPFC (prelimbic and infralimbic areas) and the BLN were performed on brains from rats at 100 days of age. Neuron and glia densities were assessed with the optical disector and then multiplied by the volume to calculate the total number of neurons and glia. In the adult mPFC, ethanol administration during adolescence resulted in a decreased number of glia in males, but not females, and had no effect on the number of neurons. Adolescent ethanol exposure had no effects on glia or neuron number in the BLN. These results suggest that glia cells in the prefrontal cortex are particularly sensitive to binge-like exposure to ethanol during adolescence in male rats only, potentially due to a decrease in proliferation in males or protective mechanisms in females.

    The gene EG:22E5.5 or CG4199 (accession number O77266, Q9W529) from Berkeley Drosophila Genome Project (BDGP) was found using the partial amino acid sequences of three tryptic peptides obtained from purified Drosophila virilis diaphorase-1. This gene is located on the X chromosome at position 2C9–2C10. The structure of the gene reveals three exons and two long introns. Using BDGP, we found six transcripts in this gene. The difference between these transcripts is in their 5′ ends; the 3′ ends of the six transcripts are identical. Thirty-four ESTs from different cDNA libraries were found, most of them from Schneider L2 cell culture (SH) cDNA library. The transcripts are represented at very low level in the cells of different organs and at different stages of Drosophila development. Using RT-PCR, we obtained five of these transcripts in cDNA samples from female adult flies. However, we could not find any of them in cDNA samples from male adult flies. Moreover, we obtained only the third transcript (CG4199-RC) in the sample of testis from adult flies and the fourth transcript (CG4199-RD) in an embryo sample. None of the other five transcripts were found in the samples of different organs and in the samples obtained at different stages of Drosophila development.

    Full Text Available Early life events induce alterations in neural function in adulthood. Although rearing in an enriched environment (EE has a great impact on behavioral development, the effects of enriched rearing on sociosexual behavior remain unclear. In this study, we investigated the effects of rearing in an EE on male copulatory behavior and its underlying neurobiological mechanisms in Wistar-Imamichi rats. Three-week-old, recently weaned rats were continuously subjected to a standard environment (SE or an EE comprised of a large cage with several objects, such as toys, tunnels, ladders, and a running wheel. After 6 weeks, rats reared in an EE (EE rats showed decreased sexual activity compared with rats reared in a SE (SE rats. This included a lower number of ejaculations and longer latencies in three consecutive copulatory tests. In addition, EE rats showed decreased emotional responsiveness and less locomotor behavior in an open field. In a runway test, on the other hand, sexual motivation toward receptive females in EE males was comparable to that of SE males. Furthermore, following exposure to a female, increases in serotonin levels in the nucleus accumbens and the striatum were significantly suppressed in EE males, whereas dopaminergic responses were similar between the groups. Female-exposure-induced increases in the levels of plasma corticosterone and testosterone were also suppressed in EE rats compared to SE rats. These data suggest that rearing in an EE decreases male copulatory behavior, and serotonin and hormonal regulating systems may regulate the differences in sociosexual interactions that result from distinct rearing environments.

    Full Text Available Abstract Background Symptoms of hyperactivity are believed to fade with age leaving ADHD adults mostly inattentive and impulsive. Our aim was to test this assertion using objective measures of hyperactivity, impulsivity and inattention. Method Participants were 40 subjects with ADHD (23M/17F; 35±10 yrs and 60 healthy adults (28M/32F; 29±9 yrs blindly assessed using Wender-Reimherr interview ratings, Structured Clinical Interview for DSM-IV Disorders and DSM-IV criteria. Infrared motion capture systems tracked head and leg movements during performance of a No-4’s cognitive control task. Subjects also completed the Conners’ CPT-II. Results ADHD and controls differed significantly in activity and attention. Effect sizes for activity measures (d’ = 0.7–1.6 were, on average, two-fold larger than differences in attention or impulsivity, correlated more strongly with executive function ratings and were more discriminatory (ROC area = 0.83 for activity composite, 0.65 for No-4’s distraction composite, 0.63 for Conners’ CPT-II confidence index, 0.96 for the combined activity and attention diagnostic index. This finding was true for subjects with the predominantly inattentive subtype as well as subjects with combined or predominantly hyperactive/impulsive subtype. Males and females with ADHD were equally active. The superior accuracy of activity measures was confirmed using Random Forest and predictive modeling techniques. Conclusions Objectively measured hyperactivity persists in adults with ADHD and is a more discriminative feature of the disorder than computerized measures of inattention or impulsivity. This finding supports the hypothesis that a deficient ability to sit still remains a defining feature of the disorder in adults when it is measured objectively.

    Abnormalities in emotion recognition are frequently reported in depression. However, emotion recognition is not compromised in some studies, and confidence judgments, which are essential for social interaction, have not been considered to date. Due to the high prevalence rate of depression in women, and sex differences in emotion recognition, the aim of the present study was to investigate emotion recognition and confidence judgments in women with depression. A sample of female patients with depressive disorders (n=45) was compared with female healthy controls (n=30) in their ability to correctly identify facial emotion expressions along with confidence judgments. Groups performed similarly on emotional face recognition and showed no difference regarding confidence ratings. A negative correlation between self-assessed depression and response confidence was found. While some limitations of the study must be taken in consideration (e.g., small number of items per emotion category, low severity of depression), abnormalities in emotion recognition do not seem to be a major feature of depression. As self-assessed depression is accompanied by low response confidence for emotional faces, it is crucial to further examine the role of confidence judgments in emotion recognition, as underconfidence may foster interpersonal insecurity in depression.

    Full Text Available Manipulation of serotonin (5HT during early development has been shown to induce long-lasting morphological changes within the raphe nuclear complex and serotonergic circuitry throughout the brain. Recent studies have demonstrated altered raphe-derived 5HT transporter (SERT immunoreactive axonal expression in several cortical target sites after brief perinatal exposure to selective 5HT reuptake inhibitors such as citalopram (CTM. Since the serotonergic raphe nuclear complex projects to the olfactory bulb (OB and perinatal 5HT disruption has been shown to disrupt olfactory behaviors, the goal of this study was to further investigate such developmental effects in the OB of CTM exposed animals. Male and female rat pups were exposed to CTM from postnatal day 8-21. After animals reach adulthood (>90 days, OB tissue sections were processed immunohistochemically for SERT antiserum. Our data revealed that the density of the SERT immunoreactive fibers decreased ~40% in the OB of CTM exposed male rats, but not female rats. Our findings support a broad and long-lasting change throughout most of the 5HT system, including the OB, after early manipulation of 5HT. Because dysfunction of the early 5HT system has been implicated in the etiology of neurodevelopmental disorders such as autism spectrum disorders (ASDs, these new findings may offer insight into the abnormal olfactory perception often noted in patients with ASD.

The French health authority recommended all prescribers of hormonal contraception (HCP) to favour second-generation HCP. To evaluate the consequences of these recommendations on female acne. A prospective multicentre study using a standardised questionnaire completed by 1,724 women. The mean age was 26.57 years; 58.7% of the women had changed their HCP during the last 12 months. The initial ratio of first or second/third or fourth-generation drugs was 5.5%/82.9% which changed after the recommendations to 70.6%/29.4%. Among the patients who switched from third or fourth to first or second-generation drugs, 83.9% considered that their acne had worsened (p<0.0001). In those patients who received a local acne treatment, 72.1% had additional systemic treatment. This study confirms the important rise in prescriptions of first or second-generation HCP. This switch has resulted in a significant increase in acne, requiring treatment for the large majority of patients, thus confirming the role of a hormonal factor in female acne. PMID:27312707

    Numerous basic and epidemiological studies have connected prenatal maternal immune activation with the occurrence of schizophrenia and/or autism. Depending on subtle differences in protocols of the used animal model, a variety of behavioral abnormalities has been reported. This study investigated behavioral differences in Wistar rat offspring of both genders, exposed to the 100 μg/kg per day dose of lipopolysaccharide (LPS) in late embryogenesis (embryonic days 15 and 16), while tested at their adolescent and young adult age (postnatal days 40 and 60, respectively). Immune activation was confirmed by detecting high levels of TNF-α and IL-6 in dam blood withdrawn 2h after the first dose of LPS. The animals were assessed in three consecutive trials of locomotor activity (novelty exploration, response to i.p. saline injection and challenge with 0.5mg/kg amphetamine), Morris water maze and social interaction tests. Overt behavioral dysfunction was perceived in adult rats only, and these changes were gender-distinctive. When compared with control rats, LPS females displayed baseline hypolocomotion and a decreased reactivity to amphetamine, while LPS males exhibited spatial learning (acquisition trials) and memory (probe trial) impairments. Prenatal treatment did not affect the time spent in social interaction. As maternal exposure to LPS in late gestation resulted in behavioral changes in offspring in early adulthood, it may model schizophrenia-like, but not autism-like endophenotypes. However, lack of a potentiated response to amphetamine testified that this model could not mimic positive symptoms, but rather certain traits of cognitive dysfunction and deficit symptoms, in males and females, respectively.

  5. WE-E-BRE-01: An Image-Based Skeletal Dosimetry Model for the ICRP Reference Adult Female - Internal Electron Sources

    International Nuclear Information System (INIS)

    Purpose: Limitations seen in previous skeletal dosimetry models, which are still employed in commonly used software today, include the lack of consideration of electron escape and cross-fire from cortical bone, the modeling of infinite spongiosa, the disregard of the effect of varying cellularity on active marrow self-irradiation, and the lack of use of the more recent ICRP definition of a 50 micron surrogate tissue region for the osteoprogenitor cells - shallow marrow. These limitations were addressed in the present dosimetry model. Methods: Electron transport was completed to determine specific absorbed fractions to active marrow and shallow marrow of the skeletal regions of the adult female. The bone macrostructure was obtained from the whole-body hybrid computational phantom of the UF series of reference phantoms, while the bone microstructure was derived from microCT images of skeletal region samples taken from a 45 year-old female cadaver. The target tissue regions were active marrow and shallow marrow. The source tissues were active marrow, inactive marrow, trabecular bone volume, trabecular bone surfaces, cortical bone volume and cortical bone surfaces. The marrow cellularity was varied from 10 to 100 percent for active marrow self-irradiation. A total of 33 discrete electron energies, ranging from 1 keV to 10 MeV, were either simulated or modeled analytically. Results: The method of combining macro- and microstructure absorbed fractions calculated using MCNPX electron transport was found to yield results similar to those determined with the PIRT model for the UF adult male in the Hough et al. study. Conclusion: The calculated skeletal averaged absorbed fractions for each source-target combination were found to follow similar trends of more recent dosimetry models (image-based models) and did not follow current models used in nuclear medicine dosimetry at high energies (due to that models use of an infinite expanse of trabecular spongiosa)

    The sexually dimorphic organization in perinatal rat brain is influenced by steroid hormones. Exposure to high levels of estrogen or endocrine-disrupting compounds during perinatal period may perturb this process, resulting in compromised reproductive physiology and behavior as observed in adult In our recent observation neonatal exposure of the female rats to estradiol-17β resulted in down-regulation of TNF-α, up-regulation of COX-2 and increase in SDN-POA size in pre-optic area in the adulthood. It is known that the control of reproductive performance in female involves a complex interplay of the hypothalamus, pituitary, and ovary. The present study was undertaken to understand the possible molecular mechanism involved in changes observed in the ovarian morphology and expression of selected genes in the ovary. Administration of estradiol-17β (100 μg) on day 2 and 3 after birth revealed up-regulation of ER-α, ER-β, COX-2 and down-regulation of TNF-α expression. Also the decrease in the ovarian weight, altered ovarian morphology and changes in the 2D protein profiles were also seen. This is apparently the first report documenting that neonatal estradiol exposure modulates TNF-α and COX-2 expression in the ovary as seen during adult stage. Our results permit us to suggest that cues originating from the modified brain structure due to neonatal exposure of estradiol-17β remodel the ovary at the molecular level in such a way that there is a disharmony in the reproductive function during adulthood and these changes are perennial and can lead to infertility and changes of reproductive behavior.

    We tested the hypothesis that the nuclear progesterone receptor (nPR) is involved in respiratory control and mediates the respiratory stimulant effect of progesterone. Adult female mice carrying a mutation in the nPR gene (PRKO mice) and wild-type controls (WT) were implanted with an osmotic pump delivering vehicle or progesterone (4 mg/kg/day). The mice were instrumented with EEG and neck EMG electrodes connected to a telemetry transmitter. The animals were placed in a whole body plethysmograph 7 days after surgery to record ventilation, metabolic rate, EEG and neck EMGs for 4 consecutive hours. The animals were exposed to hypercapnia (5% CO2), hypoxia (12% O2) and hypoxic-hypercapnia (5% CO2+12% O2-5 min each) to assess chemoreflex responses. EEG and EMG signals were used to characterize vigilance states (e.g., wake, non-REM, and REM sleep). PRKO mice exhibited similar levels of minute ventilation during non-REM and REM sleep, and higher frequencies of sighs and post-sigh apneas during non-REM sleep compared to WT. Progesterone treatment increased minute ventilation and metabolic rate in WT and PRKO mice during non-REM sleep. In WT mice, but not in PRKO mice, the ventilation under hypercapnia and hypoxic hypercapnia was enhanced after progesterone treatment. We conclude that the nPR reduces apnea frequency during non-REM sleep and enhances chemoreflex responses to hypercapnia after progesterone treatment. These results also suggest that mechanisms other than nPR activation increase metabolic rate in response to progesterone treatment in adult female mice. PMID:24945655

    Tamoxifen (TAM), a selective estrogen receptor modulator, has frequently been used in the treatment of breast cancer. In view of the fact that cognitive deficits in women who receive adjuvant chemotherapy for breast cancer is a common health problem, using female animal models for investigating the cognitive effects of TAM administration may improve our knowledge of TAM therapy. Therefore, the present study assessed the role of dorsal hippocampal cholinergic nicotinic receptors (nAChRs) in the effect of TAM administration on memory retrieval in ovariectomized (OVX) and non-OVX female rats using a passive avoidance learning task. Our results showed that pre-test administration of TAM (2-6mg/kg) impaired memory retrieval. Pre-test intra-CA1 microinjection of nicotine (0.3-0.5μg/rat) reversed TAM-induced memory impairment. Pre-test intra-CA1 microinjection of mecamylamine (0.1-0.3μg/rat) plus 2mg/kg (an ineffective dose) of TAM impaired memory retrieval. Pre-test intra-CA1 microinjection of the same doses of nicotine and mecamylamine by themselves had no effect on memory retrieval. In OVX rats, the administration of TAM (6mg/kg) produced memory impairment but pre-test intra-CA1 microinjection of nicotine (0.5μg/rat) had no effect on TAM response. Moreover, the administration of an ineffective dose of TAM (2mg/kg) had no effect on memory retrieval in OVX rats, while pre-test intra-CA1 microinjection of mecamylamine (0.3μg/rat) impaired memory retrieval. Taken together, it can be concluded that the impairing effect of TAM on memory formation may be modulated by nAChRs of the CA1 regions. It seems that memory impairment may be considered as an important side effect of TAM. PMID:27072849

    Approximately 5-7% of acute-care patients suffer from bacteremia. Bacteremia may give rise to bacterial spread to different tissues. Conventional imaging procedures as X-ray, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and ultrasound are often first-line imaging methods for identification and localization of infection. These methods are, however, not always successful. Early identification and localization of infection is critical for the appropriate and timely selection of therapy. The aim of this study was thus; a head to head comparison of (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) to PET with tracers that potentially could improve uncovering of infectious lesions in soft tissues. We chose (11)C-methionine, (11)C-PK11195, and (68)Ga-citrate as tracers and besides presenting their bio-distribution we validated their diagnostic utility in pigs with experimental bacterial infection. Four juvenile 14-15 weeks old female domestic pigs were scanned seven days after intra-arterial inoculation in the right femoral artery with a porcine strain of S. aureus using a sequential scanning protocol with (18)F-FDG, (11)C-methionine, (11)C-PK11195 and (68)Ga-citrate. This was followed by necropsy of the pigs consisting of gross pathology, histopathology and microbial examination. The pigs primarily developed lesions in lungs and neck muscles. (18)F-FDG had higher infection to background ratios and accumulated in most infectious foci caused by S. aureus, while (11)C-methionine and particularly (11)C-PK11195 and (68)Ga-citrate accumulated to a lesser extent in infectious foci. (18)F-FDG-uptake was seen in the areas of inflammatory cells and to a much lesser extent in reparative infiltration surrounding necrotic regions. PMID:27069765

    The hypothalamic-pituitary-adrenal (HPA) axis is activated in response to stressors and is controlled by neurons residing in the paraventricular nucleus of the hypothalamus (PVN). Although gonadal steroid hormones can influence HPA reactivity to stressors, the exact mechanism of action is not fully understood. It is known, however, that estrogen receptor β (ERβ) inhibits HPA reactivity and decreases anxiety-like behavior in rodents. Since ERβ is co-expressed with oxytocin (OT) in neurons of the PVN, an ERβ-selective agonist was utilized to test the whether ERβ decreases stress-induced HPA reactivity and anxiety-like behaviors via an OTergic pathway. Adult gonadectomized male and female rats were administered diarylpropionitrile, or vehicle, peripherally for 5days. When tested for anxiety-like behavior on the elevated plus maze (EPM), diarylpropionitrile-treated males and females significantly increased time on the open arm of the EPM compared to vehicle controls indicating that ERβ reduces anxiety-like behaviors. One week after behavioral evaluation, rats were subjected to a 20minute restraint stress. Treatment with diarylpropionitrile reduced CORT and ACTH responses in both males and females. Subsequently, another group of animals was implanted with cannulae directed at the lateral ventricle. One week later, rats underwent the same protocol as above but with the additional treatment of intracerebroventricular infusion with an OT antagonist (des Gly-NH2 d(CH2)5 [Tyr(Me)(2), Thr(4)] OVT) or VEH, 20min prior to behavioral evaluation. OT antagonist treatment blocked the effects of diarylpropionitrile on the display of anxiety-like behaviors and plasma CORT levels. These data indicate that ERβ and OT interact to modulate the HPA reactivity and the display of anxiety-like behaviors. PMID:24631553

    It is not so common to aspirate foreign body in normal adults without any predisposing factors as compared to children and those with the altered neurological state. Endobronchial foreign bodies are one of the causes of obstructive pneumonia and difficult to diagnose as signs and symptoms are often nonspecific. However, once they are diagnosed, they can generally be removed, leading to rapid and drastic resolution of symptoms. Bronchoscopy is the gold standard in the identification and localization of an airway foreign body and also for better management of the ailment. However with the help of virtual bronchoscopy one can decide the location of the foreign body before any invasive intervention and being noninvasive it can be performed in follow-up easily to check the patency of airways. It is not possible to detect the exact size of foreign body with the virtual bronchoscopy. In this article, we report a case of unnoticed foreign body aspiration in a 49-year-old female patient who was initially treated for pneumonia. However, due to nonresolution of opacity contrast enhanced computed tomography thorax with virtual and flexible bronchoscopy were performed, which revealed a foreign body in the right lower lobe bronchus that was removed with biopsy forceps in piecemeal. In her follow-up visit, she underwent virtual broncoscopy that revealed clear airways. Thus, detailed history and high index of suspicion is required for nonresolving pneumonias that may occur due to unnoticed foreign body/ies in an adult. PMID:27578936

    Full Text Available Objective: This study describes morphological variations of the face of hypertensive women when compared to non-hypertensives.Material and Methods: Digital images of the faces of 54 non-hypertensive and 41 hypertensive women were used in this study. Forty-one manuallypositioned landmarks were on front face images, while twenty-eight landmarks were collected on left and right face images, the Cartesiancoordinates of which were extracted using an image analysis and processing software. The faces were then aligned using Procrustes alignmentof the Cartesian coordinates to eliminate size differences and rotational translation. The size residuals left after the alignment were then used toreconstruct the face truss network using thin-plate spline grids. Variations in facial morphology were then explored using the methods of relativewarps analysis and partial warps analysis. Results: Principal Component Analysis revealed that in both populations of females, five or sixprincipal components contribute most to the variation that exist among individuals. Results for fluctuating asymmetry are higher compared toindividual variation, with even higher values in hypertensive individuals compared to non-hypertensive. Scatterplots of residual asymmetrybetween the two groups further revealed the distinct differences existing between them.

    Acne in the adult female often presents as a chronic condition that can have a considerable negative psychological, social and emotional impact on the affected individual. Estimated prevalence rates of adult female acne vary widely according to study type. Case reports and clinical examinations estimate the prevalence of clinical acne at 10-12%, while survey estimates of physiological disease states are as high as 54%. Two subtypes of adult female acne may be defined according to time of onset: 'persistent' and 'late-onset', accounting for approximately 80 and 20% of cases, respectively. Postadolescent acne is generally mild-to-moderate in severity and presents with more inflammatory lesions and fewer comedones compared to adolescent acne. Furthermore, the impact of acne on the quality of life is often greater in adult females than in younger individuals. Despite these important differences, the key principles of acne treatment in the adult female do not differ significantly from those of other age groups. However, specific characteristics relating to the adult female should be considered when selecting a treatment regimen. PMID:24280643

    The oviposition deterrent and ovicidal of seven herbal essential oils derived from Citrus sinensis, Cymbopogon citratus, Eucalyptus glubulus, Illicium verum, Lavandula angustifolia, Mentha piperita, and Zingiber cussumunar were assessed against the gravid female of housefly, Musca domestica L., under laboratory conditions and compared with commercial insecticide (10% w/v cypermethrin). They were assayed at three concentrations (1.0, 5.0, and 10.0%) where plastic cups containing 1 ml of desired oil concentration and cotton pad soaked with 10 ml of milk solution (10% w/v) were used as oviposition substrate. The 0.1 ml of deferent concentrations was dropped on ten housefly eggs, which were used for ovicidal activity. The number of eggs laid and the hatched larvae in each cup was recorded to evaluate the oviposition deterrent and ovicidal activities of the herbal essential oils. High concentration (10%) of herbal essential oils showed high percent effective repellency (ER). The 10% I. verum oil caused complete oviposition deterrence (100% ER, oviposition activity index (OAI) = -1.0), followed by Z. cussumunar, M. piperita, L. angustifolia, C. citratus, C. sinensis, and E. glubulus oils with 97.20, 88.55, 88.14, 87.93, 76.68, and 57.00% ER, respectively. As the concentration of herbal essential oils increased from 1.0, 5.0, and up to 10.0% concentration, the hatching rate decreased. Ten percent I. verum oil gave the maximum inhibiting rate at 97.3% (LC50 value of 6.85%); in addition, the other herbal essential oils showed the minimum inhibiting rate of 3.3-22.7%. On the other hand, cypermethrin 10% w/v showed complete oviposition deterrence (100% ER, OAI = -1.0) and ovicidal activity (100% inhibiting rate). Our data showed that I. verum oil have high potential of oviposition deterrence and ovicide housefly control. PMID:24894080

    The current prevalence of diet-induced overweight and obesity in adolescents and adults is continuously growing. Although the detrimental biochemical and metabolic consequences of obesity are widely studied, its impact on stress-coping behavior and its interaction with specific exercise doses (in terms of intensity, duration and frequency) need further investigation. To this aim, we fed adolescent rats either an obesogenic diet (cafeteria diet, CAF) or standard chow (ST). Each group was subdivided into four subgroups according to the type of treadmill intervention as follows: a sedentary group receiving no manipulation; a control group exposed to a stationary treadmill; a low-intensity treadmill group trained at 12 m/min; and a higher intensity treadmill group trained at 17 m/min. Both the diet and treadmill interventions started at weaning and lasted for 8 weeks. Subjects were tested for anxiety-like behavior in the open field test and for coping strategies in the two-way active avoidance paradigm at week 7 and were sacrificed at week 8 for biometric and metabolic characterization. CAF feeding increased the weight gain, relative retroperitoneal white adipose tissue (RWAT %), and plasma levels of glucose, insulin, triglycerides and leptin and decreased the insulin sensitivity. Treadmill intervention partially reversed the RWAT% and triglyceride alterations; at higher intensity, it decreased the leptin levels of CAF-fed animals. CAF feeding decreased the motor activity and impaired the performance in a two-way active avoidance assessment. Treadmill intervention reduced defecation in the shuttle box, suggesting diminished anxiety. CAF feeding combined with treadmill training at 17 m/min increased the time spent in the center of the open field and more importantly, partially reversed the two-way active avoidance deficit. In conclusion, this study demonstrates that at doses that decreased anxiety-like behavior, treadmill exercise partially improved the coping strategy

    In insects, the process whereby juvenile hormone (JH) regulates short-day (SD)-induced reproductive diapause has been previously investigated. However, we still do not understand the mechanism by which JH regulates long-day (LD)-induced reproductive diapause. In this study, we use a cabbage beetle, Colaphellus bowringi, which is a serious pest of cruciferous vegetables in Asia capable of entering reproductive diapause under LD conditions, as a model to test whether JH regulates female reproductive diapause similar to the mechanism of SD-induced diapause. Our results showed that the JH analog (JHA) methoprene significantly induced ovarian development but inhibited lipid accumulation of diapause-destined adults. Meanwhile, the transcripts of the vitellogenin (Vg) genes were upregulated, whereas the expression of the fat synthesis and stress tolerance genes were downregulated. RNA interference of the JH candidate receptor gene methoprene-tolerant (Met) blocked JH-induced ovarian development and Vg transcription, suggesting a positive regulatory function for JH-Met signaling in reproduction. Furthermore, under reproduction-inducing conditions, Met depletion promoted a diapause-like phenotype, including arrested ovarian development and increased lipid storage, and stimulated the expression of diapause-related genes involved in lipid synthesis and stress tolerance, suggesting JH-Met signaling plays an important role in the inhibition of diapause. Accordingly, our data indicate that JH acts through Met to facilitate development of the reproductive system by upregulating Vg expression while inhibiting diapause by suppressing lipid synthesis and stress tolerance in the cabbage beetle. Combined with previous studies in SD-induced reproductive diapause, we conclude that JH may regulate female reproductive diapause using a conserved Met-dependent pathway, regardless of the length of the photoperiod inducing diapause in insects.

    A cardiac mass (3 × 5 × 3 cm) was detected at the base between the right auricular wall and right vena cava of a slaughtered 6-month-old female mixed-breed pig during a meat inspection. The tumor comprised infiltrative prominent interweaving fascicles of Schwann cells with Verocay bodies. Moreover, the ganglion cells were scattered or aggregated throughout the neoplastic tissue. The ganglion and Schwann cells had neither cellular atypism nor mitosis. On the basis of the bearing site as well as the morphological and immunohistochemical features, this is the first case of a cardiac ganglioneuroma in a pig. PMID:26256406

    Full Text Available Abstract Background The tick Rhipicephalus sanguineus is the species with the largest worldwide distribution and is proven to be involved in the transmission of pathogens such as Babesia canis, Ehrlichia canis, Coxiella burnetii, Rickettsia ricketsii, Rickettsia conorii, among others. Studies have demonstrated acquisition of resistance to some of the active principles used in commercial formulations of acaricides. Tagetes patula (Asteraceae is a plant with highlighted economic and commercial importance due to the production of secondary metabolites with insecticide and acaricide potential, mainly flavonoids, thiophenes and terpenes. Methods The in vitro acaricide action of the ethanolic 70% extract from aerial parts of T. patula, obtained by percolation, was evaluated against larvae and engorged adult females of Rhipicephalus sanguineus by immersion test for 5 minutes. The chemical characterization of this extract was done by liquid chromatography coupled with mass spectrometry (LC-MS, using direct injection of sample. Results Despite T. patula not proving lethal to adults in any of the concentrations tested, at 50.0 mg/mL oviposition rate decreased by 21.5% and eliminated 99.78% of the larvae. Also it was determined that the best results were obtained with 5 minutes of immersion. From the chromatographic analysis twelve O-glycosylated flavonoids were identified. Conclusions This is the first report on the acaricidal activity of T. patula extract against Rh. sanguineus. If we consider the application of the product in the environment, we could completely eliminate the larval stage of development of the ixodid Rh. sanguineus.

  4. Is whole body bone mineral density measured by the dual energy X-ray absorptiometry applied to evaluate risk of osteoporosis among Japanese adult females?

    International Nuclear Information System (INIS)

    The purpose of this study is to measure whole body fat accurately, the dual energy X-ray absorptiometry (DXA) is widely utilized. Simultaneously, bone mineral density (BMD) of the whole body can also be measured. BMD is one of important information to diagnose osteoporosis. However, it is not established to use whole body BMD for this diagnosis. It is recommended that lumbar and/or hip BMD should be used for diagnosing osteoporosis by the guideline for prevention and treatment of osteoporosis. Although it is possible to measure whole body BMD and lumbar and/or hip BMD separately at the same visit, it is inevitable to expose patients to more X-ray. Therefore, an aim of this study is to elucidate the relationship between whole body BMD and lumbar BMD to find the cut off point of whole body BMD for screening of osteoporosis. Two hundred and thirty six Japanese adult females were ascertained to this study. Whole body BMD and lumbar BMD of each subject were measured with the use of Delphi W (Hologic, USA). One hundred and sixty five subjects were judged as possible osteoporosis (less than 80% of young adult mean (YAM) of lumbar BMD and/or definite fracture of lumbar vertebras). The cut off point of whole body BMD for screening possible osteoporosis was estimated by receiver operated characteristic (ROC) analysis. The cut off point of whole body BMD was 84% of YAM, equivalent to 80% of YAM of lumbar BMD, with the following sensitivity and specificity (0.84 and 0.79, respectively), indicating that whole body BMD could be used for screening osteoporosis.

    It is well established that sexually dimorphic brain regions, which are critical for reproductive physiology and behavior, are organized by steroid hormones during the first 2 weeks after birth in the rodents. In our recent observation, neonatal exposure to estradiol-17β (E2) in the female rat revealed increase in cyclooxygenase 2 (COX-2) level, sexually dimorphic nucleus (SDN)-pre-optic area (POA) size and down-regulation of synaptogenesis related genes in POA in the adult stage. In the present study, using the same animal model, the protein profile of control and neonatally E2-treated POA was compared by 1D-SDS-PAGE, and the protein that shows a change in abundance was identified by LC-MS/MS analysis. Results indicated that there was a single protein band, which was down-regulation in E2-treated POA and it was identified as spectrin alpha chain, non-erythrocytic 1 (SPTAN1). Consistently, the down-regulation of SPTAN1 expression was also confirmed by reverse transcription polymerase chain reaction (RT-PCR) and Western blot analysis. The SPTAN1 was identified as a cytoskeletal protein that is involved in stabilization of the plasma membrane and organizes intracellular organelles, and it has been implicated in cellular functions including DNA repair and cell cycle regulation. The evidence shows that any mutation in spectrins causes impairment of synaptogenesis and other neurological disorders. Also, protein-protein interaction analysis of SPTAN1 revealed a strong association with proteins such as kirrel, actinin, alpha 4 (ACTN4) and vinculin (VCL) which are implicated in sexual behavior, masculinization and defeminization. Our results indicate that SPTAN1 expression in the developing rat brain is sexually dimorphic, and we suggest that this gene may mediate E2-17β-induced masculinization and defeminization, and disrupted reproductive function in the adult stage.

  7. Specific absorbed fractions of energy at various ages from internal photon sources: 5, Fifteen-year-old male and adult female

    International Nuclear Information System (INIS)

    Specific absorbed fractions (PHI's) in various organs of the body (target organs) from sources of monoenergetic photons in various other organs (source organs) are tabulated. In this volume PHI-values are tabulated for a fifteen-year-old male or an adult female (55 to 58 kg). These PHI-values can be used in calculating the photon component of the dose-equivalent rate in a given target organ from a given radionuclide that is present in a given source organ. The International Commission on Radiological Protection recognizes that the endosteal, or bone surface, cells are the tissue at risk for bone cancer. We have applied the dosimetry methods developed for beta-emitting radionuclides deposited in bone to follow the transport of secondary electrons that were freed by photon interactions through the microscopic structure of the skeleton. With these methods we can estimate PHI in the endosteal cells and can better estimate PHI in the active marrow; the latter is overestimated with other methods of Snyder et al. at photon energies below 200 keV. 12 refs., 2 tabs

    Our objective was to characterize Berkshire female pigs associated with climatic factors by examining the interactions between two pig groups (pure English Berkshire females and crossbred females between Landrace and Large White) for reproductive performance in a humid subtropical zone. We analyzed 63,227 first-service records of 11,992 females in 12 herds. Climate data were obtained from four weather stations located close to the herds. Mean daily maximum temperatures (Tmax) and daily average relative humidity (ARH) for different time periods around servicing and farrowing of each female were coordinated with that female's reproductive performance data. Multilevel mixed-effects models were applied to the data. There were two-way interactions between the pig groups and either Tmax or ARH for weaning-to-first-mating interval (WMI) and number of total pigs born (TPB; P TPB decreased by 0.3 pigs as Tmax increased from 20 to 30 °C (P < 0.05), whereas that in crossbred females decreased by 0.4 pigs (P < 0.05). Therefore, we recommend producers apply advanced cooling systems for Berkshire females. PMID:26250151

    Attacks on humans by wild pigs (Sus scrofa) have been documented since ancient times. However, studies characterizing these incidents are lacking. In an effort to better understand this phenomenon, information was collected from 412 wild pig attacks on humans. Similar to studies of large predator attacks on humans, data came from a variety of sources. The various attacks compiled occurred in seven zoogeographic realms. Most attacks occurred within the species native range, and specifically in rural areas. The occurrence was highest during the winter months and daylight hours. Most happened under non-hunting circumstances and appeared to be unprovoked. Wounded animals were the chief cause of these attacks in hunting situations. The animals involved were typically solitary, male and large in size. The fate of the wild pigs involved in these attacks varied depending upon the circumstances, however, most escaped uninjured. Most human victims were adult males traveling on foot and alone. The most frequent outcome for these victims was physical contact/mauling. The severity of resulting injuries ranged from minor to fatal. Most of the mauled victims had injuries to only one part of their bodies, with legs/feet being the most frequent body part injured. Injuries were primarily in the form of lacerations and punctures. Fatalities were typically due to blood loss. In some cases, serious infections or toxemia resulted from the injuries. Other species (i.e., pets and livestock) were also accompanying some of the humans during these attacks. The fates of these animals varied from escaping uninjured to being killed. Frequency data on both non-hunting and hunting incidents of wild pig attacks on humans at the Savannah River Site, South Carolina, showed quantitatively that such incidents are rare.

Para a análise estatística, foram considerados, no modelo de análise da variância, os efeitos de bloco, PDF, PBO e da interação (bloco x PDF, entre outros. O PDF influenciou, significativamente, as concentrações de lactato no sangue e cortisol na saliva. Suínos que descansaram 5 e 7 horas apresentaram maior concentração de lactato em relação aos animais que descansaram 3 e 9 horas. No transporte, a freqüência cardíaca foi muito maior em relação aos demais locais avaliados. Concluiu-se que o incremento do PDF não promove mudanças na freqüência cardíaca, nas concentrações de glicose e CPK no sangue e cortisol na saliva, mas interfere na concentração de lactato no sangue dos suínos.The aim of the research was to evaluate the effect of pig lairage time (PDF=3, 5, 7 and 9 hours and evaluate the effect of pig position into the truck (PBO during transportation to slaughterhouse, in winter or summer conditions, on some physiologic parameters evaluated on 64 heavyweight females with mean liveweight of 130kg during pre-slaughter events.

    Full Text Available Abstract Background Interstitial cystitis is a chronic condition associated with bladder inflammation and, like a number of other chronic pain states, symptoms associated with interstitial cystitis are more common in females and fluctuate during the menstrual cycle. The aim of this study was to determine if estrogens could directly modulate signalling pathways within bladder sensory neurons, such as extracellular signal-related kinase (ERK and p38 mitogen-activated protein (MAP kinases. These signalling pathways have been implicated in neuronal plasticity underlying development of inflammatory somatic pain but have not been as extensively investigated in visceral nociceptors. We have focused on lumbosacral dorsal root ganglion (DRG neurons projecting to pelvic viscera (L1, L2, L6, S1 of adult female Sprague-Dawley rats and performed both in vitro and in vivo manipulations to compare the effects of short- and long-term changes in estrogen levels on MAPK expression and activation. We have also investigated if prolonged estrogen deprivation influences the effects of lower urinary tract inflammation on MAPK signalling. Results In studies of isolated DRG neurons in short-term (overnight culture, we found that estradiol and estrogen receptor (ER agonists rapidly stimulated ER-dependent p38 phosphorylation relative to total p38. Examination of DRGs following chronic estrogen deprivation in vivo (ovariectomy showed a parallel increase in total and phosphorylated p38 (relative to β-tubulin. We also observed an increase in ERK1 phosphorylation (relative to total ERK1, but no change in ERK1 expression (relative to β-tubulin. We observed no change in ERK2 expression or phosphorylation. Although ovariectomy increased the level of phosphorylated ERK1 (vs. total ERK1, cyclophosphamide-induced lower urinary tract inflammation did not cause a net increase of either ERK1 or ERK2, or their phosphorylation. Inflammation did, however, cause an increase in p38

At age 120 days, animals were subjected to a glucose tolerance test or decapitated. Plasma concentrations of various biomarkers and PMAT gene abundance were monitored. P4-ND (vs. CT-ND rats showed elevated circulating levels of lipids. CT-FRD rats displayed high (vs. CT-ND plasma concentrations of lipids, leptin, adiponectin and plasminogen activator inhibitor-1 (PAI-1. Lipidemia and adiponectinemia were high (vs. P4-ND in P4-FRD rats. Although P4 failed to prevent FRD-induced hyperleptinemia, it was fully protective on FRD-enhanced plasma PAI-1 levels. PMAT leptin and adiponectin mRNAs were high in CT-FRD and P4-FRD rats. While FRD enhanced PMAT PAI-1 mRNA abundance in CT rats, this effect was absent in P4 rats. Our study supports that a preceding P4-enriched milieu prevented the enhanced prothrombotic risk induced by FRD-elicited high PAI-1 production.

    2015-01-01

    To investigate the effect of estradiol valerate on lipid metabolism of female Bama Xiang-pigs and its mechanism, a total of 20 healthy female Bama Xiang-pigs of 35 days old were selected and randomly divided into two groups ( control group and experimental group) with each group had 10 replicates and each replicate had 1 pig. The pigs in the control group were fed a basal diet, while the pigs in the experimental group were fed the basal diet supplemented with 0. 66 mg/kg estradiol valerate ( equivalent to 0. 5 mg/kg estradiol) for 120 d. The results showed as follows:1) diets supplemented with estradiol valerate significantly decreased the final body weight, body weight gain and body fat percentage of female Bama Xiang-pigs ( P0.05);the mRNA relative expression levels of FAS, ACC and LPL in abdominal subcutaneous adipose were significantly decreased ( P0.05); the mRNA relative expression levels of PPAR-γ, FAS, ER-α and ER-βin perirenal adipose were significantly decreased ( P0.05) . Those results indicate that estradiol va-lerate can control the body weight gain and fat deposition and improve the levels of blood GLU and TG of fe-male Bama Xiang-pigs effectively. In addition, there may be exist two ways for estradiol valerate to regulate the lipid metabolism, one is that influencing the lipid metabolism in different white adipose tissues by regulating the expression of genes related to lipogenic and lipolytic metabolism, the other one is that modulating the ex-pression of LPL by regulating the expression of estrogen receptors, then to affect the lipogenic metabolism.%本试验旨在研究戊酸雌二醇对雌性巴马香猪脂质代谢的影响及其作用机制。采用单因子试验设计,选取20头健康的35日龄雌性巴马香猪随机分为2组,即对照组与试验组,每组10个重复,每个重复1头猪。对照组饲喂基础饲粮,试验组饲喂在基础饲粮中添加0.66 mg/kg戊酸雌二醇(相当于0.5 mg/kg雌二醇)的

  17. A morphometric analysis of glomerular and tubular alterations following fast-neutron irradiation of the pig and monkey kidney

    International Nuclear Information System (INIS)

    Purpose: The morphologic responses of the pig and monkey kidney to fractionated fast-neutron irradiation were assessed. Methods and Materials: The right kidney of approximately 14-week-old female Large White pigs was irradiated with 6.6-12.2 Gy of fast neutrons (42 MeVd→Be) given as 12 fractions over 18 days; the left kidney served as the contralateral unirradiated kidney. Both kidneys were removed at necropsy 2 years postirradiation. In addition, the remaining hypertrophied kidney of four unilaterally nephrectomized adult rhesus monkeys was irradiated with a total dose of 11.0 Gy fast neutrons (45 MeVp→Be) given in an identical fractionation regimen to that used in the pig studies. These kidneys were removed when the animals exhibited renal failure, between 32-94 weeks postirradiation. Glomeruli were assessed for the presence of pathologic features, including intercapillary eosinophilic material (ICE), ectatic capillaries, thrombi, hemorrhage, and sclerosis. The relative proportion of renal cortex occupied by glomeruli, interstitium, normal, or abnormal tubules was determined using a Chalkley point grid. Results: The incidence of normal glomeruli, ectatic capillaries, thrombosis, and periglomerular fibrosis were significantly different in the irradiated pig kidneys compared with the unirradiated contralateral kidneys (p ≤ 0.02). Linear regression analysis demonstrated a significant dose relationship in terms of normal glomeruli, ectatic capillaries, and ICE (r ≥ 0.64; p ≤ 0.04). Irradiation was also associated with a significant (p < 0.0001) decrease and increase in the volume of renal cortex occupied by normal and abnormal tubules, respectively. Similar morphometric changes were noted in the irradiated monkey kidneys. Conclusions: The morphologic changes seen in the pig and monkey kidney after fractionated irradiation with fast neutrons are similar to those previously noted after single-dose or fractionated-photon irradiation. These findings support the

    Recent studies have shown that cell cycle inhibitors encoded by the Ink4a gene locus constrain the self-renewing activity of adult stem cells of the hematopoietic and nervous systems. Here we report that knockout (KO) of the Cables1 [cyclin-dependent kinase (CDK)-5 and ABL enzyme substrate 1] cell cycle-regulatory gene in mice has minimal to no effect on hematopoietic stem cell (HSC) dynamics. However, female Cables1-null mice exhibit a significant expansion of germ cell (oocyte) numbers throughout adulthood. This is accompanied by a dramatic elevation in the number of atretic immature oocytes within the ovaries and an increase in the incidence of degenerating oocytes retrieved following superovulation of CABLES1-deficient females. These outcomes are not observed in mice lacking p16INK4a alone or both p16INK4a and p19ARF. These data support recent reports that adult female mice can generate new oocytes and follicles but the enhancement of postnatal oogenesis by Cables1 KO appears offset by a reduction in oocyte quality, as reflected by increased elimination of these additional germ cells via apoptosis. This work also reveals cell lineage specificity with respect to the role that specific CDK-interacting proteins play in restraining the activity of adult germline versus somatic stem cells.

    2001-11-01

    One of the costly and welfare-reducing problems in modern pig production is tail biting. Tail biting is an abnormal behaviour, characterized by one pig's dental manipulation of another pig's tail. Tail biting can be classified into two groups: the pre-injury stage, before any wound on the tail is present, and the injury stage, where the tail is wounded and bleeding. Tail biting in the injury stage will reduce welfare of the bitten pig and the possible spread of infection is a health as well as welfare problem. The pigs that become tail biters may also suffer, because they are frustrated due to living in a stressful environment. This frustration may result in an excessive motivation for biting the tails of pen mates. This review aims to summarize recent research and theories in relation to tail biting. PMID:11681870

    Full Text Available Abstract Background Hepatitis E virus (HEV infection is a serious health problem in developing countries and is also increasingly reported in industrialized regions. HEV is considered a zoonotic agent and strains isolated from swine and human sources are genetically similar. Thus, HEV is of increasing importance to both public and animal health. The aim of the present study was to evaluate the distribution of HEV in a large population of pigs from herds located in different autonomous regions throughout Spain. Results The presence of anti-HEV IgG antibodies was analyzed in 1141 swine serum samples (corresponding to 381 pigs younger than 6 months and 760 pigs older than 6 months collected from 85 herds. Herds were located in 6 provinces in 4 autonomous regions throughout Spain. At least one pig tested positive for anti-HEV IgG in over 80% of herds. Of individual pigs, 20.4% (233/1141 were positive for anti-HEV IgG, with the prevalence being higher in adult pigs than in those under 6 months (30.2% vs. 15.5%. A subset of serum samples taken at 2- to 5-week intervals showed that seroprevalence dropped between 3 and 11 weeks of age, and then rose significantly by the 15th week. Pigs were also examined for the presence of HEV-RNA by RT-PCR. Of pigs tested for the presence of HEV-RNA 18.8% (64/341 were positive, with at least one pig in almost half of the herds testing positive. HEV-RNA amplicons from several positive pigs were sequenced and all were of genotype 3. Conclusions HEV was found to be widely distributed among swine farms across Spain, with the prevalence being highest among animals older than 6 months. These results indicate that HEV infection either is or is likely to become endemic in the Spanish swine population.

    Adopting a 2 × 2 × 2 factorial design, this study evaluated whether continuous straw provision by racks, tail docking and gender (barrows vs. females) have an effect on the prevalence of lung lesions and oesophago-gastric ulcer (OGU) visually scored at slaughter in 635 Italian heavy pigs (169 ± 4 kg). The lung lesions were very low (72% of pigs with score 0), and were not significantly different among the experimental groups. Overall, OGU was diagnosed in 47% of the pigs. The consumption of small amounts of straw (70 g/day/pig) represented a protective factor against the onset of OGU (OR: 0.27). Barrows were more likely than females to have OGU (OR: 1.52), while no significant differences between docked and undocked pigs were detected. Nevertheless, the presence of straw acted as a protective factor particularly in undocked pigs (OR: 0.16), suggesting that in this group the absence of rooting material may have a stronger effect on welfare.

    Full Text Available Abstract Chlamydiaceae are Gram-negative obligate intracellular bacteria. They are responsible for a broad range of diseases in animals and humans. In pigs, Chlamydia suis, Chlamydia abortus, Chlamydia pecorum and Chlamydia psittaci have been isolated. Chlamydiaceae infections in pigs are associated with different pathologies such as conjunctivitis, pneumonia, pericarditis, polyarthritis, polyserositis, pseudo-membranous or necrotizing enteritis, periparturient dysgalactiae syndrome, vaginal discharge, return to oestrus, abortion, mummification, delivery of weak piglets, increased perinatal and neonatal mortality and inferior semen quality, orchitis, epididymitis and urethritis in boars. However, Chlamydiaceae are still considered as non-important pathogens because reports of porcine chlamydiosis are rare. Furthermore, Chlamydiaceae infections are often unnoticed because tests for Chlamydiaceae are not routinely performed in all veterinary diagnostic laboratories and Chlamydiaceae are often found in association with other pathogens, which are sometimes more easily to detect. However, recent studies have demonstrated that Chlamydiaceae infections in breeding sows, boars and piglets occur more often than thought and are economically important. This paper presents an overview on: the taxonomy of Chlamydiaceae occurring in pigs, diagnostic considerations, epidemiology and pathology of infections with Chlamydiaceae in pigs, public health significance and finally on prevention and treatment of Chlamydiaceae infections in pigs.

    Objective To observe the effect of adult cold storage on the longevity and reproductive capacity of female Nasonia vitripennis. Methods The female N. vitripennis emerged on different days were cold stored at 15 ℃ for different period.Their longevity, parasitic capacity and reproductive capacity were then measured. Results The longevity of female N. vitripennis was extended after cold storage at adult stage. However, as the cold storage time prolonged, the parasitic and reproductive capacities were compromised. At a cold storage time for less than 12 d, the impact on these capacities of female N. vitripennis was not remarkable. In contrast, after cold storage of over 12 d, the egg production and parasitic capacities declined linearly. After cold stored for 24 d, the parasitic ratio of Boettcherisca peregrina by N. vitripennis reduced to 35% from 85% before cold storage and the average emerging parasitoid progeny to 6 from 33 per fly pupa. However, the female adult rate and the body length of the progeny were not affected. Conclusion Adult cold storage extends the longevity of female N. vitripennis at the cost of reproductive capability.%目的 观察成虫期冷藏对丽蝇蛹集金小蜂雌蜂寿命和繁殖能力的影响.方法 考察羽化后不同时间的丽蝇蛹集金小蜂雌蜂在15 ℃冷藏不同时间后的寿命、寄生和繁殖能力.结果 成虫期冷藏可延长丽蝇蛹集金小蜂雌蜂的成虫寿命,但随冷藏时间的延长,丽蝇蛹集金小蜂雌蜂的寄生能力和产卵能力均受到不同程度的负面影响,当冷藏时间不超过12 d时,丽蝇蛹集金小蜂雌蜂的寄生和产卵能力均不受显著影响,而超过12 d后,其产卵和寄生能力均呈线性下降趋势;冷藏前至冷藏后24d,雌蜂对棕尾别麻蝇蛹的寄生率由85%下降至35%,蝇蛹的平均出蜂数由33头/蛹下降至6头/蛹,而后代的雌蜂比和体长均不受影响.结论 成虫期冷藏可延长丽蝇蛹集金小蜂雌蜂的寿命,但影响其繁殖能力.

    Numerical modeling of sound propagation in the airways requires accurate knowledge of the airway geometry. These models are often validated using human and animal experiments. While many studies documented the geometric details of the human airways, information about the geometry of pig airways is scarcer. In addition, the morphology of animal airways can be significantly different from that of humans. The objective of this study is to measure the airway diameter, length and bifurcation angles in domestic pigs using computed tomography. After imaging the lungs of 3 pigs, segmentation software tools were used to extract the geometry of the airway lumen. The airway dimensions were then measured from the resulting 3 D models for the first 10 airway generations. Results showed that the size and morphology of the airways of different animals were similar. The measured airway dimensions were compared with those of the human airways. While the trachea diameter was found to be comparable to the adult human, the diameter, length and branching angles of other airways were noticeably different from that of humans. For example, pigs consistently had an early airway branching from the trachea that feeds the superior (top) right lung lobe proximal to the carina. This branch is absent in the human airways. These results suggested that the human geometry may not be a good approximation of the pig airways and may contribute to increasing the errors when the human airway geometric values are used in computational models of the pig chest.

  3. Aspects of the metabolism of U-14C arginine, U-14C histidine and U-14C lysine by adult female Glossina morsitans during pregnancy

    International Nuclear Information System (INIS)

    U-14C arginine, U-14C histidine or U-14C lysine was injected into haemolymph of pregnant female Glossina morsitans. Radioactivity was detected in the post-parturient female and its larval offspring mostly in arginine or histidine, but in the case of lysine injection radioactivity was detected in the two life stages in lysine lipids and a range of nonessential amino acids. The pattern of radioactivity in the developing oocyte and larva was related to growth characteristics of these young stages. Whereas arginine and histidine were mostly excreted unchanged, lysine derived radioactivity was detected in the excreted uric acid and expired carbon dioxide; radioactivity in such products was greater in early than late pregnancy.

  9. Understanding the female offender.

    Science.gov (United States)

    Cauffman, Elizabeth

    2008-01-01

    Although boys engage in more delinquent and criminal acts than do girls, female delinquency is on the rise. In 1980, boys were four times as likely as girls to be arrested; today they are only twice as likely to be arrested. In this article, Elizabeth Cauffman explores how the juvenile justice system is and should be responding to the adolescent female offender. Cauffman begins by reviewing historical trends in arrest rates, processing, and juvenile justice system experiences of female offenders. She also describes the adult outcomes commonly observed for female offenders and points out that the long-term consequences of offending for females are often more pronounced than those for males, with effects that extend to the next generation. She also considers common patterns of offending in girls, as well as factors that may increase or decrease the likelihood of offending. She then reviews what is known about effective treatment strategies for female offenders. Female delinquents have a high frequency of mental health problems, suggesting that effective prevention efforts should target the mental health needs of at-risk females before they lead to chronic behavior problems. Once girls with mental health problems come into the juvenile justice system, says Cauffman, diverting them to community-based treatment programs would not only improve their individual outcomes, but allow the juvenile justice system to focus on cases that present the greatest risk to public safety. Evidence is emerging that gender-specific treatment methods can be effective for female offenders, especially when treatment targets multiple aspects of offenders' lives, including family and peer environments. But it is also becoming clear that female offenders are not a homogeneous group and that treatment ultimately should be tailored to suit individual needs defined more specifically than by gender alone. Despite myriad differences between male and female offending, many of the primary causes of

    Full Text Available The behavior of pigs can be divided into several categories, which include maternal behavior, aggressive behavior, sexual behavior, feeding behavior, and various other forms of emotional behavior. Domestication has caused many changes in the original behaviour of boar, such as in reproductive and sexual behaviour, and has lead to a general increase in social tolerance between animals. Further modifications in behaviour are also possible, as suggested by the optimization of environmental factors which affect maternal behavior. The behaviour of a sow after farrowing appeared as a consequence of natural selection for protection of piglets from predators in the wild boar population, and affects the survival of piglets and the longevity of the sow in breeding. The behavior of the sows which includes the protection of the piglets from predators appears as a consequence of natural selection in the wild boar population. Familiarity with the molecular mechanisms which determine the patterns of behavior enables understanding of behavioral problems such as aggressiveness and helps the improvement of the well-being of pigs. Research conducted on pigs has determined that there are regions on chromosomes 2, 6, 10, 14, and 15, and chromosome X which can explain the genetic aspect of appearance of some behavioral patterns in sows. The goal of this paper is to illustrate the behavioral patterns appeared in the populations of domestic breeds of pigs and their genetic aspects, which knowledge may provide some help in improving the production qualities and creating higher economic gain during production.

    Full Text Available Research was conducted between 2005-2009 in Barzava, Arad county. The villagers breed pigs traditionally, the animals having the freedom to roam the outskirts of the villages. Over the years the domestic sows (Sus scrofa domesticus which had been let by their owners to roam the forests for mast and acorn, have mated with wild boars (Sus scrofa ferus, thus obtaining crossbreeds in various colours – either resembling the female or the male. In Bazava the total number of swine is 1820 specimens out of which 546 is formed by hybrids or crossbreeds in 2009. In the case of these hybrids the length of the head together with that of the trunk can reach 150-170 cm. An adult male can have a weight of 150-200 kg and the female 100-150 kg. These specimens are easily recognizable by the fact that they have the trunk covered in thick, long, spiky hairs. There are also other external characteristics of these crossbreeds. Data has been gathered on what concerns the colour and the length of the hair, external features, maintenance and feeding. Behavioural observations have been made also. The local people appreciate a lot these hybrids because of their qualitative meat, out of which they obtain traditional dishes, combining this meat with that from domestic pigs and veal. Moreover, the maintenance of these hybrids is very low-cost, the only conditions which have to be met being simple shelters during the night and during the winter. The demand for such animals is great. These hybrids are being bought by the Zoos or are used for repopulating the areas in which the wild boars are on the verge of extinction because of excessive poaching. Foreign buyers are also interested in these hybrids, wanting to breed them in special parks and then to organize hunting outings.

For sexual caress behavior, there was no significant difference between Group A and B, as well as Group B and C (P>0.05), However, the difference between Group A and C was significant (P0.05). But the differences were significant between Group A and C, as well as between Group B and C (P0.05). There was no significant difference in sexual frequency between Group B and C (P>0.05). But the differences were significant between Group A and B, as well as Group A and C (P<0.001). Conclusion Affected by traditional sexual attitude, the main sexual behavior of female adults in Guangzhou was still sexual intercourse style .With the increase of age, the frequency of sexual intercourse of female adults decreased, whereas sexual caress behavior and sexual position style alteration behavior increased for improving sexual satisfaction. On the other hand, though the most female adults held a negative attitude toward masturbation and oral sex behavior, the younger women, who were influenced by open mind, gradually accepted oral sex as one kind of sexual life behavior.

    Maternal infection during pregnancy increases the risk for the offspring to develop schizophrenia. However, it is still not fully understood which biochemical mechanisms are responsible for the emergence of neuropsychiatric symptoms following prenatal immune activation. The serotonin (5-hydroxytryptamine, 5-HT) and glutamate system have prominently been associated with the schizophrenia pathophysiology but also with the mechanism of antipsychotic drug actions. Here, we investigated the behavioral and cellular response to 5-HT2A and metabotropic glutamate (mGlu)2/3 receptor stimulation in male and female offspring born to lipopolysaccharide (LPS)-treated mothers. Additionally, we assessed protein expression levels of prefrontal 5-HT2A and mGlu2 receptors. Prenatally LPS-exposed male and female offspring showed locomotor hyperactivity and increased head-twitch behavior in response to the 5-HT2A receptor agonist DOI. In LPS-exposed male offspring, the mGlu2/3 receptor agonist LY379268 failed to reduce DOI-induced prepulse inhibition deficits. In LPS-males, the behavioral changes were further accompanied by enhanced DOI-induced c-Fos protein expression and an up-regulation of prefrontal 5-HT2A receptors. No changes in either 5-HT2A or mGlu2 receptor protein levels were found in female offspring. Our data support the hypothesis of an involvement of maternal infection during pregnancy contributing, at least partially, to the pathology of schizophrenia. Identifying biochemical alterations that parallel the behavioral deficits may help to improve therapeutic strategies in the treatment of this mental illness. Since most studies in rodents almost exclusively include male subjects, our data further contribute to elucidating possible gender differences in the effects of prenatal infection on 5-HT2A and mGlu2/3 receptor function.

    Blood samples were collected from 69 'healthy' female alpacas aged ≥12 months from 11 properties in South Australia. The 10-90 percentile ranges of the 16/19 analytes measured in this sample population were within the published ranges of four healthy alpaca populations from other geographic locations. Marginal exceptions were glutamate dehydrogenase and bicarbonate. Potassium was notably elevated, probably because of haemolysis of some samples. The sample size was insufficient to provide the appropriate statistical power to define diagnostic references ranges according to international standards. The health status of the sample population of alpacas was presumptive based on a physical examination. PMID:27021895

    Axial compression of the mouse tibia is used to study strain-adaptive bone (re)modeling. In some studies, comparisons between mice of different ages are of interest. We characterized the tibial deformation and force–strain relationships in female C57Bl/6 mice at 5-, 12- and 22-months age. A three-gauge experimental method was used to determine the strain distribution at the mid-diaphysis, while specimen-specific finite element analysis was used to examine strain distribution along the tibial ...

This review explores themajor research findings accumulated internationally over the last decade (2003-2013 about women'sviolence and crimes. The focus of the review is the intimate partner violence (IPV and sexual violencecommitted by females, the psychopathy and violence risk assessment, and the treatment and recidivism ofthese female offenders. Although the female offender topic is too wide to review all crime typologies (childphysical abuse is not included, for example the review indicates that: there are legal and police biases inthe treatment of women offenders; women can commit the same IPV and share the motivations of maleoffenders; sexual violence has a low prevalence, but there are many limitations in this research topic;predicting the risk of non-specific violence is feasible with the available tools; psychopathy is less prevalentamong adult female offenders, although there are fewer differences with male offenders among adolescentsamples; research about treatments is very limited and there are not effectiveness evidences; and last,recidivism rates for violent crimes are very low (in cases where information is available.

    Ameloblastic fibroma (AF) is rare benign odontogenic tumour which usually occurs in the first two decades of life. It can occur either the mandible or maxilla but it is most frequently found in the posterior region of the mandible. Treatment of AF in usual is a conservative approach, such as enucleation and curettage but the aggressive lesions require a radical approach. A more radical approach should be considered in older patients who have likely high recurrence tendency. This report describes a case of AF in a 38-year-old female patient identified during a routine radiographic exam. Tomographic examination through three-dimensional reconstruction indicated vestibular fenestration of the cortical bone, with involvement of lingual cortical bone as the lession extended to the posterior region. We removed the tumor under local anesthesia. In this case patient has continued to be followed frequently and has been disease-free for 3 years. PMID:27011753

    To evaluate image quality of female pelvic computed tomography (CT) scans reconstructed with the adaptive statistical iterative reconstruction (ASIR) technique combined with low tube-voltage and to explore the feasibility of its clinical application. Ninety-four patients were divided into two groups. The study group used 100 kVp, and images were reconstructed with 30%, 50%, 70%, and 90% ASIR. The control group used 120 kVp, and images were reconstructed with 30% ASIR. The noise index was 15 for the study group and 11 for the control group. The CT values and noise levels of different tissues were measured. The contrast to noise ratio (CNR) was calculated. A subjective evaluation was carried out by two experienced radiologists. The CT dose index volume (CTDIvol) was recorded. A 44.7% reduction in CTDIvol was observed in the study group (8.18 ± 3.58 mGy) compared with that in the control group (14.78 ± 6.15 mGy). No significant differences were observed in the tissue noise levels and CNR values between the 70% ASIR group and the control group (p = 0.068-1.000). The subjective scores indicated that visibility of small structures, diagnostic confidence, and the overall image quality score in the 70% ASIR group was the best, and were similar to those in the control group (1.87 vs. 1.79, 1.26 vs. 1.28, and 4.53 vs. 4.57; p = 0.122-0.585). No significant difference in diagnostic accuracy was detected between the study group and the control group (42/47 vs. 43/47, p = 1.000). Low tube-voltage combined with automatic tube current modulation and 70% ASIR allowed the low CT radiation dose to be reduced by 44.7% without losing image quality on female pelvic scan.

  5. Immunization of pigs against infection with Schistosoma japonicum using ultraviolet-attenuated cercariae

    International Nuclear Information System (INIS)

    Since pigs are important in the zoonotic transmission of schistosomiasis japonica in China, a veterinary vaccine might contribute to the control of the disease in humans. Pigs were immunized with three doses each of 10 000 cercariae of Schistosoma japonicum attenuated with ultraviolet light (400 μWatt.min/cm2). The experiment was performed with portable irradiation equipment in a rural area of the Hubei Province (P.R. China). A challenge infection of 1000 untreated cercariae was given 2.5 or 6 months after the last immunization, and age-matched naive pigs were challenged as a control. Immunized pigs developed about 90% resistance against the challenge. The liver egg load of these animals was reduced by over 90%. Less than 0.01% of the immunizing cercariae developed to adult parasites and the vaccination had no apparent adverse influence on the pig's health. (Author)

    Female mice from independently bred lines previously selected over 50 generations for increased voluntary wheel-running behavior (S1, S2) resist high energy (HE) diet-induced obesity (DIO) at adulthood, even without actual access to running wheels, as opposed to randomly bred controls (CON). We investigated whether adult S mice without wheels remain DIO-resistant when exposed - via the mother - to the HE diet during their perinatal stage (from 2 weeks prior to conception until weaning on post-natal day 21). While S1 and S2 females subjected to HE diet either perinatally or from weaning onwards (post-weaning) resisted increased adiposity at adulthood (as opposed to CON females), they lost this resistance when challenged with HE diet during these periods combined over one single cycle of breeding. When allowed one-week access to wheels (at week 6-8 and at 10 months), however, tendency for increased wheel-running behavior of S mice was unaltered. Thus, the trait for increased wheel-running behavior remained intact following combined perinatal and post-weaning HE exposure, but apparently this did not block HE-induced weight gain. At weaning, perinatal HE diet increased adiposity in all lines, but this was only associated with hyperleptinemia in S lines irrespective of gender. Because leptin has multiple developmental effects at adolescence, we argue that a trait for increased physical activity may advance maturation in times of plenty. This would be adaptive in nature where episodes of increased nutrient availability should be exploited maximally. Associated disturbances in glucose homeostasis and related co-morbidities at adulthood are probably pleiotropic side effects. PMID:26850290

    We examined home range behavior of female feral pigs (Sus scrofa) in a heavily hunted population on Fort Benning Military Reservation in west-central Georgia, USA. We used Global Positioning System location data from 24 individuals representing 18 sounders (i.e., F social groups) combined with markrecapture and camera-trap data to evaluate evidence of territorial behavior at the individual and sounder levels. Through a manipulative experiment, we examined evidence for an inverse relationship between population density and home range size that would be expected for territorial animals. Pigs from the same sounder had extensive home range overlap and did not have exclusive core areas. Sounders had nearly exclusive home ranges and had completely exclusive core areas, suggesting that female feral pigs on Fort Benning were territorial at the sounder level but not at the individual level. Lethal removal maintained stable densities of pigs in our treatment area, whereas density increased in our control area; territory size in the 2 areas was weakly and inversely related to density of pigs. Territorial behavior in feral pigs could influence population density by limiting access to reproductive space. Removal strategies that 1) match distribution of removal efforts to distribution of territories, 2) remove entire sounders instead of individuals, and 3) focus efforts where high-quality food resources strongly influence territorial behaviors may be best for long-term control of feral pigs.

    2015-01-01

    A new genus, Nubensia Spies, is proposed for N. nubens (Edwards, 1929), n. comb., based on morphological evaluation of both adult sexes, the pupa and larva. The material studied includes name-bearing syntype specimens and the first reared associations linking three life stages for individual members of this species. The larva represents a unique morphotype previously described incompletely only from studies of subfossil chironomid remains. The problems with placement of the species in any previously established genus are discussed in detail, and various related issues in taxonomy and nomenclature are commented on. The verified distribution of N. nubens ranges from the British Isles and central Europe to the western Mediterranean, including northern Africa, with possible extensions to Turkey and central Asia. Larvae have been found on mostly coarse, variously covered substrates near the shores of lakes and banks of slowly flowing running waters, under both oligotrophic and eutrophic conditions.

    Pig feed is mainly based on cereals where phosphorus (P) is mostly present in inositol hexaphosphate (IP6), which is not readily available to monogastric animals. More available P sources are often added to ensure that pigs’ requirements are fulfilled; this results in high excretion levels of P. The digestibility of P depends on phytase activity and amount of IP6 in feedstuffs. The overall aim was to study effects of liquid feeding, P levels and phytase supplementation on digestibility and pe...

    Full Text Available Animals are commonly used to model the human spine for in vitro and in vivo experiments. Many studies have investigated similarities and differences between animals and humans in the lumbar and thoracic vertebrae. However, a quantitative anatomic comparison of calf, pig, and human cervical spines has not been reported.To compare fundamental structural similarities and differences in vertebral bodies from the cervical spines of commonly used experimental animal models and humans.Anatomical morphometric analysis was performed on cervical vertebra specimens harvested from humans and two common large animals (i.e., calves and pigs.Multiple morphometric parameters were directly measured from cervical spine specimens of twelve pigs, twelve calves and twelve human adult cadavers. The following anatomical parameters were measured: vertebral body width (VBW, vertebral body depth (VBD, vertebral body height (VBH, spinal canal width (SCW, spinal canal depth (SCD, pedicle width (PW, pedicle depth (PD, pedicle inclination (PI, dens width (DW, dens depth (DD, total vertebral width (TVW, and total vertebral depth (TVD.The atlantoaxial (C1-2 joint in pigs is similar to that in humans and could serve as a human substitute. The pig cervical spine is highly similar to the human cervical spine, except for two large transverse processes in the anterior regions ofC4-C6. The width and depth of the calf odontoid process were larger than those in humans. VBW and VBD of calf cervical vertebrae were larger than those in humans, but the spinal canal was smaller. Calf C7 was relatively similar to human C7, thus, it may be a good substitute.Pig cervical vertebrae were more suitable human substitutions than calf cervical vertebrae, especially with respect to C1, C2, and C7. The biomechanical properties of nerve vascular anatomy and various segment functions in pig and calf cervical vertebrae must be considered when selecting an animal model for research on the spine.

    Experiences during critical periods, such as the neonatal and adolescence, play a critical role in determining adult stress-coping behavior. Based on the aforementioned we developed an experimental protocol, which included a neonatal experience and a social stress during adolescence. The serotonergic system is known as an important modulator of coping ability and, in general, emotional balance in both normal and pathological states, such as depression and anxiety, for which females are more vulnerable. Thus in the present work we used female rats and determined 5-HT, 5-hydroxyindoleacetic acid (5-HIAA), and 5-hydroxytryptamine receptor type 1A (5-HT(1A)) receptor levels in the prefrontal cortex (PFC) and the amygdala (AMY). During postnatal days 10-13 (PND 10-13) rat pups were exposed to a T-maze, one arm of which lead to the mother. One group of animals was allowed contact with the mother (rewarded-receiving expected reward (RER)), whereas the other was denied the expected reward (DER). High performance liquid chromatography (HPLC) analysis revealed that in both the PFC and in AMY, adult RER animals had higher basal 5-HT levels. Furthermore, in the AMY of this group of animals, higher levels of 5-HT(1A) receptors were detected by Western blot analysis. In adulthood rats were exposed to the Forced Swimming Test/Stress (FST/S). RER animals not exposed to the adolescent stress exhibited longer immobility time during both the first and second day of FST. Corticosterone levels following the FST fell faster in the DER animals. Adolescent stress affected the responses to the adult FSS only in the DER animals, which had decreased 5-HT in the AMY and increased immobility time on both days of the FST, compared with the DER, not stressed in adolescence. The phenotype of the DER animals is in line with the "match-mismatch" hypothesis, which states that if two events during critical periods of life "match" in being mildly stressful, their interaction can be adaptive.

    Pigs are important in the epidemiology of toxoplasmosis in North America. Seroprevalence of Toxoplasma gondii infection in 525 domestic pigs (337 backyard raised, 188 farm raised) in Oaxaca State, Mexico was determined using the modified agglutination test (MAT, cutoff 1:25). Antibodies to T. gondii were found in 58 (17.2%) of the 337 backyard pigs with MAT titers of 1:25 in 10, 1:50 in 12, 1:100 in 18, 1:200 in 6, 1:400 in 6, 1:800 in 3, and 1:1,600 in 3. Seropositive pigs were found in 39 (37.9%) of 103 homes in all 7 municipalities surveyed. Seroprevalence of T. gondii infection in backyard pigs varied with age, gender, geographic region, climate, and altitude. High seroprevalence was found in pigs ≥ 9-mo-old (40%), in females (40%), in pigs from the Istmo region (33.3%), and in those raised in a tropical climate (65%). Seroprevalence was higher (24.5%) in pigs raised at 100-660 m above sea level than in those at 20-60 m of altitude (14.2%). With respect to farm pigs, only 1 (0.5%, MAT titer 1:100) of 188 pigs from 5 farms was positive for anti- T. gondii antibodies. The results affirm that the management system (outdoor vs. indoor system with biosecurity) is a key factor in the epidemiology of porcine toxoplasmosis. Because there is no national system of determining the T. gondii infection status at the time of slaughter, precautions should be taken while handling pig carcasses, and all pork should be cooked thoroughly before human consumption.

    Full Text Available The green swordtail X. hellerii Heckel, 1848 is a commercially important ornamental species. As phenotypic males with the sword extension of the caudal fin are more valuable economically than fish lacking the sword, masculinization by means of 17-α-Methyltestosterone (MT was tested. Populations of female broodstocks were fed MT-treated feeds (20, 35 and 50 mg MT kg-1 feed at a rate of 50 g of MTtreated feed per kilogram of fish biomass (5% body weight [BW] for 45 consecutive days to cause development of male secondary sexual characteristics, specifically the growth of the sword extension.Use of MT feed at 5% BW for 45 d resulted in 100% masculinization, whereas 0% masculinization occurred in green swordtails fed control feed. There were no significant differences between MT-treated groups in the proportion of phenotypic males. Also we found no significant differences in mortality among experimental groups. No degeneration of swords was seen 200 d after the last day of experimental feed treatment. According to our finding, the use of MT-treated feeds can increase the production of highervalue phenotypic male green swordtails and enhance profitability for aquaculturists.

    Most patients with chronic granulomatous disease (CGD) have mutations in the X-linked CYBB gene that encodes gp91phox, a component of the phagocyte NADPH oxidase. The resulting X-linked form of CGD is usually manifested in boys. Rarely, X-CGD is encountered in female carriers with extreme expression of the mutated gene. Here, we report on a woman with a novel mutation in CYBB (CCG[90-92]-->GGT), predicting Tyr30Arg31-->stop, Val in gp91phox, who presented with clinical symptoms at the age of 66. The mutation was present in heterozygous form in genomic DNA from her leukocytes but was fully expressed in mRNA from these cells, indicating that in her leukocytes the X chromosome carrying the nonmutated CYBB allele had been inactivated. Indeed, only 0.4% to 2% of her neutrophils showed NADPH oxidase activity. This extreme skewing of her X-chromosome inactivation was not found in her cheek mucosal cells and is thus not due to a general defect in gene methylation on one X chromosome. Moreover, the CYBB mutation was not present in the DNA from her cheek cells and was barely detectable in the DNA from her memory T lymphocytes. Thus, this patient shows a somatic mosaic for the CYBB mutation, which probably originated during her lifetime in her bone marrow. PMID:15308575

Methods Pig pancreas tissue was digested with collagenase P through continuous infusion. Pig islets was purified by Ficoll discontinuous density gradient centrifugation medium. Dithizone (DTZ) staining was used to observe the morphology of islet cells clusters (ICCS) , to count islet equivalent IEQ, and to detect the purity of the islet. AO-PI staining was used to detect islet viability and the islet function assessed by insulin release assay in vitro. Results The number of the islets collected was (4 387 + 617) IEQ/g in average from pancreas before purification, and (3 192 ±756) IEQ/g pancreas after purification. The average purity of islets cells was (60.15 ±2.35) %, and the motilityrate was (80.00 ± 0.47) %. Conclusions The islet cells obtained by this method have better purity and good biological activity. That' s to say the Semi-automatic isolation and purification of small-eared pig islet cells is successful and feasible. The established method can be applied in large-scale purification of fully functional islet cells from pig pancreas, and can meet the need for further studies of xenotransplantation.

    In recent years, dataflow languages such as Pig Latin have emerged as flexible and powerful tools for handling complex analysis tasks on big data. These languages support schema flexibility as well as common programming patterns such as iteration. They offer extensibility through user......-defined functions while running on top of scalable distributed platforms. In doing so, these languages enable analytical tasks while avoiding the limitations of classical query languages such as SQL and SPARQL. However, the tuple-oriented view of general-purpose languages like Pig does not match very well...... this problem by proposing extensions to Pig that deal with linked data in RDF to bridge the gap between Pig and SPARQL for analytics. These extensions are realized by a set of user-defined functions and rewriting rules, still allowing to compile the enhanced Pig scripts to plain MapReduce programs. For all...

    Skin lesions were collected from 15 adult crossbred pigs maintained at the pig farm of ICAR Research Complex for the North-Eastern Hill Region, Umiam, a hilly region of the state of Meghalaya, India. Skin scrapings of these 15 animals were examined by KOH digestion method. Presence of mites were detected in five animals which were indistinguishable from Sarcoptes scabiei var. suis. Infected pigs were treated with a single dose of Ivermectin at 200 ug/kg body weight, subcutaneously. No mites were recovered from treated pigs after a period of 10 days of post-treatment. The presence of S. scabiei var. suis in pigs from this part of the country has never been reported. This infestation has great significance because it affects the growth rate and feed conversion significantly, specially to the grower and weaned pigs. It can be concluded that S. scabiei var. suis infestation is prevalent in hilly region of Meghalaya. The pig producers are generally unaware about the severity of the problem of mite infestation, so precaution should be taken to prevent their valuable pigs from S. scabiei var. suis infestation.

    Sex is a motive force bringing a man and a woman into intimate contact. Sexuality is a central aspect of being human throughout life and encompasses sex, gender identities and roles, sexual orientation, eroticism, pleasure, intimacy, and reproduction. Sexuality is experienced and expressed in thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles and relationships. Though generally, women are sexually active during adolescence, they reach their peak orgasmic frequency in their 30 s, and have a constant level of sexual capacity up to the age of 55 with little evidence that aging affects it in later life. Desire, arousal, and orgasm are the three principle stages of the sexual response cycle. Each stage is associated with unique physiological changes. Females are commonly affected by various disorders in relation to this sexual response cycle. The prevalence is generally as high as 35-40%. There are a wide range of etiological factors like age, relationship with a partner, psychiatric and medical disorders, psychotropic and other medication. Counseling to overcome stigma and enhance awareness on sexuality is an essential step in management. There are several effective psychological and pharmacological therapeutic approaches to treat female sexual disorders. This article is a review of female sexuality. PMID:26330647

  8. Female infertility

    International Nuclear Information System (INIS)

    Infertility, defined as 1 year of unprotected intercourse without conception, is becoming of increasingly important medical concern. Fertility in both the male and the female is at its peak in the twenties. Many couples today have postponed marriage and/or childbearing into their 30s until careers are established, but at that point fertility may be diminished. The current epidemic of venereal disease has been associated with an increasing incidence of tubal scarring. In addition, the use of intrauterine devices (IUDs) and birth control pills for contraception have let to later problems with pelvic inflammatory disease (PID) and ovulation disturbances. The problem of infertility intensifies as the number of babies available for adoption decreases. Therefore, it is estimated that approximately 10-20% of couples will eventually seek medical attention for an infertility-related problem. Fortunately, marked improvements in the results of tubal surgery are concurrently occurring secondary to refinements in microsurgical techniques, and many medical alternatives to induce ovulation are being developed. The male factor causes infertility in 30-40 % of couples, and the female factor is responsible in approximately 50% of couples. No cause is found in 10-20% of couples. This chapter discusses the role of coordinated imaging in the diagnosis and therapy of infertility in the female

    Objective To investigate the suitability of miniature pigs as an animal model for otological research. Methods Microdissection of the temporal bone was performed on 10 miniature pigs and recorded on photo-graphs. Results The morphology and measurement of the external, middle and inner ear and the lateral re-cess of the miniature pigs were obtained by microdissection. Conclusion Compared to traditional animal models, the miniature pig may be a better model for biomedical research because of its many similarities in physiological functions with humans. Similarities of the temporal bone structures, including the external, middle and inner ear and the lateral recess, between the miniature pig and human make the animal a poten-tially useful model for otological research.

    Computational anthropomorphic human phantoms are useful tools developed for the calculation of absorbed or equivalent dose to radiosensitive organs and tissues of the human body. The problem is, however, that, strictly speaking, the results can be applied only to a person who has the same anatomy as the phantom, while for a person with different body mass and/or standing height the data could be wrong. In order to improve this situation for many areas in radiological protection, this study developed 18 anthropometric standing adult human phantoms, nine models per gender, as a function of the 10th, 50th and 90th mass and height percentiles of Caucasian populations. The anthropometric target parameters for body mass, standing height and other body measures were extracted from PeopleSize, a well-known software package used in the area of ergonomics. The phantoms were developed based on the assumption of a constant body-mass index for a given mass percentile and for different heights. For a given height, increase or decrease of body mass was considered to reflect mainly the change of subcutaneous adipose tissue mass, i.e. that organ masses were not changed. Organ mass scaling as a function of height was based on information extracted from autopsy data. The methods used here were compared with those used in other studies, anatomically as well as dosimetrically. For external exposure, the results show that equivalent dose decreases with increasing body mass for organs and tissues located below the subcutaneous adipose tissue layer, such as liver, colon, stomach, etc, while for organs located at the surface, such as breasts, testes and skin, the equivalent dose increases or remains constant with increasing body mass due to weak attenuation and more scatter radiation caused by the increasing adipose tissue mass. Changes of standing height have little influence on the equivalent dose to organs and tissues from external exposure. Specific absorbed fractions (SAFs) have also

The anthropometric target parameters for body mass, standing height and other body measures were extracted from PeopleSize, a well-known software package used in the area of ergonomics. The phantoms were developed based on the assumption of a constant body-mass index for a given mass percentile and for different heights. For a given height, increase or decrease of body mass was considered to reflect mainly the change of subcutaneous adipose tissue mass, i.e. that organ masses were not changed. Organ mass scaling as a function of height was based on information extracted from autopsy data. The methods used here were compared with those used in other studies, anatomically as well as dosimetrically. For external exposure, the results show that equivalent dose decreases with increasing body mass for organs and tissues located below the subcutaneous adipose tissue layer, such as liver, colon, stomach, etc, while for organs located at the surface, such as breasts, testes and skin, the equivalent dose increases or remains constant with increasing body mass due to weak attenuation and more scatter radiation caused by the increasing adipose tissue mass. Changes of standing height have little influence on the equivalent dose to organs and tissues from external exposure. Specific absorbed fractions (SAFs) have also

    Computational anthropomorphic human phantoms are useful tools developed for the calculation of absorbed or equivalent dose to radiosensitive organs and tissues of the human body.

    Full Text Available Taenia solium, a parasitic cestode that affects humans and pigs, is the leading cause of preventable epilepsy in the developing world. T. solium eggs are released into the environment through the stool of humans infected with an adult intestinal tapeworm (a condition called taeniasis, and cause cysticercosis when ingested by pigs or other humans. A control strategy to intervene within high-risk foci in endemic communities has been proposed as an alternative to mass antihelminthic treatment. In this ring strategy, antihelminthic treatment is targeted to humans and pigs residing within a 100 meter radius of a pig heavily-infected with cysticercosis. Our aim was to describe the roaming ranges of pigs in this region, and to evaluate whether the 100 meter radius rings encompass areas where risk factors for T. solium transmission, such as open human defecation and dense pig activity, are concentrated.In this study, we used Global Positioning System (GPS devices to track pig roaming ranges in two rural villages of northern Peru. We selected 41 pigs from two villages to participate in a 48-hour tracking period. Additionally, we surveyed all households to record the locations of open human defecation areas. We found that pigs spent a median of 82.8% (IQR: 73.5, 94.4 of their time roaming within 100 meters of their homes. The size of home ranges varied significantly by pig age, and 93% of the total time spent interacting with open human defecation areas occurred within 100 meters of pig residences.These results indicate that 100 meter radius rings around heavily-infected pigs adequately capture the average pig's roaming area (i.e., home range and represent an area where the great majority of exposure to human feces occurs.

    Full Text Available Animal models of obesity and metabolic dysregulation during growth (or childhood are lacking. Our objective was to increase adiposity and induce metabolic syndrome in young, genetically lean pigs. Pre-pubertal female pigs, age 35 d, were fed a high-energy diet (HED; n = 12, containing 15% tallow, 35% refined sugars and 9.1-12.9% crude protein, or a control corn-based diet (n = 11 with 12.2-19.2% crude protein for 16 wk. Initially, HED pigs self-regulated energy intake similar to controls, but by wk 5, consumed more (P<0.001 energy per kg body weight. At wk 15, pigs were subjected to an oral glucose tolerance test (OGTT; blood glucose increased (P<0.05 in control pigs and returned to baseline levels within 60 min. HED pigs were hyperglycemic at time 0, and blood glucose did not return to baseline (P = 0.01, even 4 h post-challenge. During OGTT, glucose area under the curve (AUC was higher and insulin AUC was lower in HED pigs compared to controls (P = 0.001. Chronic HED intake increased (P<0.05 subcutaneous, intramuscular, and perirenal fat deposition, and induced hyperglycemia, hypoinsulinemia, and low-density lipoprotein hypercholesterolemia. A subset of HED pigs (n = 7 was transitioned back to a control diet for an additional six weeks. These pigs were subjected to an additional OGTT at 22 wk. Glucose AUC and insulin AUC did not improve, supporting that dietary intervention was not sufficient to recover glucose tolerance or insulin production. These data suggest a HED may be used to increase adiposity and disrupt glucose homeostasis in young, growing pigs.

  1. Pigs fly on schedule with remote launchers

    International Nuclear Information System (INIS)

    The development of a new pig launcher for use in gas, oil or multi-phase pipeline applications in remote sites was discussed. The pig launcher, developed by Opsco '92 Industries Ltd., sends forth pigs of any shape or style, from a pre-loaded pig chamber at a preset cycle of up to six weeks between launches. Opsco's Remote Pig Launcher (ORPL) is also capable of providing 60 weeks of unmanned pig launching. The ORPL is designed to fit new installations but can be retrofitted to existing pig senders. The advantage of ORPL is that frequent pigging helps reduce production losses caused by liquid slugging and high level separator shutdowns at plant inlets. Operator time, and transportation to a pigging site are reduced because several pigs can be loaded during a single visit. This reduces overall operating costs. 1 fig

    Full Text Available Introduction. 21α-hydroxylase deficiency is the most frequent cause of virilization in patients with female karyotype due to exposure of a female fetus to excess of androgen. We report anatomical and cosmetic results of feminizing genital reconstruction of two related patients (second cousin with XX karyotype born with urogenital sinus anomalies (UGS and not treated at birth. Materials and Metods. Patient 1 is 6-years old with ambiguous genitalia graded as Prader V and never undergone therapy or surgery. Patient 2 is 10-years old, graded as Prader IV and subjected to hormonal therapy and clitoral amputation at the age of 6. Mobilization of urogenital sinus, pull-through of vagina and tubulization of urethra was performed in both after placement of Foley chateters in vagina and bladder by cisto-vaginoscopy. Genitoplasty involved refashioning the tissues to create minora and majora labia and, after removal of corpora, partial clitorectomy was carried in patient 1 and clitoridal reconstruction in patient 2. Result. Vaginal introitus was positioned in the vestibule region below urethral meatus. Foley chateters was removed after two weeks in narcosis and the cosmetic and anatomic result was good. Conclusion. Goals of feminizing genitoplasty are to restore, soon as possible, anatomy achieving a more feminine appareance with a vagina for menstruation, to preserve reproductive capacity and to prevent urological sequelae but it’s also important to contribute in a development of a more stable gender identity. This procedure in two stage, based on an accurate diagnosis, is good to create feminine genital appareance in children with female pseudohermaphroditism expecially if not treated at birth.

In the inside pages of the same edition are profuse photos of other pigs dressed in suits and ties. This ostentation mocks the people and mainly the 3 children who do not attend school because the money for it has been embezzled from their pockets. Decent journalists, conscious of these piggish humans, endeavor every day to make this country a decent place to live.

  7. Targeted disruption of LDLR causes hypercholesterolemia and atherosclerosis in Yucatan miniature pigs.

    Directory of Open Access Journals (Sweden)

    Bryan T Davis

    Full Text Available Recent progress in engineering the genomes of large animals has spurred increased interest in developing better animal models for diseases where current options are inadequate. Here, we report the creation of Yucatan miniature pigs with targeted disruptions of the low-density lipoprotein receptor (LDLR gene in an effort to provide an improved large animal model of familial hypercholesterolemia and atherosclerosis. Yucatan miniature pigs are well established as translational research models because of similarities to humans in physiology, anatomy, genetics, and size. Using recombinant adeno-associated virus-mediated gene targeting and somatic cell nuclear transfer, male and female LDLR+/- pigs were generated. Subsequent breeding of heterozygotes produced LDLR-/- pigs. When fed a standard swine diet (low fat, no cholesterol, LDLR+/- pigs exhibited a moderate, but consistent increase in total and LDL cholesterol, while LDLR-/- pigs had considerably elevated levels. This severe hypercholesterolemia in homozygote animals resulted in atherosclerotic lesions in the coronary arteries and abdominal aorta that resemble human atherosclerosis. These phenotypes were more severe and developed over a shorter time when fed a diet containing natural sources of fat and cholesterol. LDLR-targeted Yucatan miniature pigs offer several advantages over existing large animal models including size, consistency, availability, and versatility. This new model of cardiovascular disease could be an important resource for developing and testing novel detection and treatment strategies for coronary and aortic atherosclerosis and its complications.

    Two matched case-control studies were performed at an abattoir with a capacity of 780 pigs per hour, each study using the approximately 7000 pigs slaughtered on one day. In the first study, the severity of tail biting and pneumonia were recorded in pigs with bitten or intact tails. In the second study, the tail score, sex, and the presence of pleuritis, externally visible abscesses and trimming were recorded in pigs with bitten or intact tails. In study 1, there was no significant association between the tail score and the percentage of lung tissue affected by lesions typical of enzootic pneumonia, but there was a significant association between the severity of tail biting and the prevalence of lungs with abscesses and/or pleuritic lesions (Ptail biting, and the prevalence of external carcase abscesses and carcase trimming; the carcases of castrated males had evidence of tail biting more frequently than the carcases of females (P<0.05).

    The enzyme α1,3-galactosyltransferase (α1,3GT or GCTA1) synthesizes α1,3-galactose (α1,3Gal) epitopes (Galα1,3Galβ1,4GlcNAc-R), which are the major xenoantigens causing hyperacute rejection in pig-to-human xenotransplantation. Complete removal of α1,3Gal from pig organs is the critical step toward the success of xenotransplantation. We reported earlier the targeted disruption of one allele of the α1,3GT gene in cloned pigs. A selection procedure based on a bacterial toxin was used to select for cells in which the second allele of the gene was knocked out. Sequencing analysis demonstrated that knockout of the second allele of the α1,3GT gene was caused by a T-to-G single point mutation at the second base of exon 9, which resulted in inactivation of the α1,3GT protein. Four healthy α1,3GT double-knockout female piglets were produced by three consecutive rounds of cloning. The piglets carrying a point mutation in the α1,3GT gene hold significant value, as they would allow production of α1,3Gal-deficient pigs free of antibiotic-resistance genes and thus have the potential to make a safer product for human use.

    Results of a 12 month study of traditional guinea-pig production in the western highlands of Cameroon are reported. The mean age of guinea-pigs (Cavia porcellus L.) at first parturition, kidding interval and litter size at birth were 126.30 +/- 10.40 d, 64.8 +/- 1.70 d and 1.63 +/- 0.26 kids respectively. The annual reproductive rate was 9.18 kids/breeding doe while the doe post-partum weight was 530 g. Mean body weights at birth, presumed weaning (21 d) and 15 weeks of age were 78.36 +/- 3.20, 147.51 +/- 8.10 and 418.88 +/- 32 g respectively. Type of birth and sex had a significant effect on body weight at all ages. Birth weight dropped significantly from 83.88 +/- 2.87 g for singles to 81.57 +/- 3.40 g for twins, 74.25 +/- 2.39 g for triplets and 73.75 +/- 4.12 g for quadruplets. These differences were maintained to maturity (15 weeks). Males were generally heavier than females. Mortality rates were relatively high among kids: 24% at birth, 39% at 3 weeks and 40% at 15 weeks. Productivity indices were 0.827 kg of young weaned per doe per year, 1560 g of young weaned per kg of doe per year and 2.52 kg of young weaned per kg metabolic weight (kg 0.75) of female per year.

    Full Text Available Zoonoses in swine are increasingly becoming a global public health concern. Understanding how livestock farmers perceive animal illnesses will help to develop locally acceptable and effective public health intervention strategies to control and manage zoonoses. The authors describe Bangladeshi pig raisers’ perception of pig illnesses and their behaviour towards sick pigs. We collected qualitative data from August 2007 to September 2008. Included in our study are backyard pig raisers from three districts, namely: Faridpur, Chapainobabgonj and Tangail and nomadic herders from six districts, namely: Mymensingh, Tangail, Sherpur, Sirajgonj, Bogra and Pabna. We conducted in-depth interviews (n = 34 and made observations of human interactions with pigs (n = 18. Pig raisers reported several illnesses that caused their pigs to suffer and die. They had close contact with sick pigs whilst caring for them. They slaughtered sick pigs and consumed and sold the pork if they thought that the pig might die. They believed that pig illness could be transmitted among pigs but not between pigs and humans. The perception of pig raisers on pig illnesses and their behaviour towards sick pigs places them in close contact with potentially infectious pig secretions and excretions. Such exposure could favour zoonotic transmission of infectious diseases. A better surveillance system for pig diseases would provide an opportunity to identify the transmission of diseases, determine whether they pose a risk to humans, or whether they contribute to the emergence of diseases.

  14. Association between Influenza A Virus Infection and Pigs Subpopulations in Endemically Infected Breeding Herds.

    Andres Diaz

    Full Text Available Influenza A viruses (IAVs are distributed worldwide in birds, pigs and humans, and cause important endemic disease affecting hosts in all countries. Although pigs play a key role in the ecology of IAVs, the epidemiology of IAVs within swine herds is poorly understood. In this longitudinal study we describe the prevalence of IAVs infection in three subpopulations of pigs in 5 breeding herds in the Midwestern USA. Each herd was sampled monthly for a year and, at each visit, 30 individual nasal swabs were collected from the three subpopulations, namely, a replacement females, resident on-farm for less than 4 weeks (new gilts, b replacement females, resident on-farm for more than 4 weeks (gilts, and c neonatal pigs less than 21 days of age (piglets. Real time reverse transcriptase polymerase chain reaction (RRT-PCR was used to detect IAVs, and the association between IAVs infection and pig subpopulation was measured using a mixed logistic regression model. Nasal swabs (n = 4,190 were collected from 141 groups of pigs. At least, one IAV-positive nasal swab was found in 19.9% (n = 28 of the sampled groups, and 7.7% (n = 324 of all nasal swabs tested positive. After adjusting by annual quarter and sampling event, the odds of testing IAV positive were 7.9 (95% CI 1.4, 43.9 and 4.4 (95% CI 1.1, 17.1 times higher in groups of new gilts and piglets compared to groups of gilts, respectively. Results indicate that new gilts and piglets had higher odds of testing IAV positive than gilts in swine breeding herds and that season influences IAV infection in pigs. Based on these findings, we recommend that IAV control strategies be aimed at preventing infection before gilts are introduced into the farm, and in pigs prior to weaning.

Method: Twelve healthy pigmented guinea pigs weighted 200-250 g were included in this experiment. 5 ul of Ad5-El/E3 defected-atohl/EGFP were infused into the scala media through a hole made on the lateral wall of the cochlea. Six of the 12 animal were killed 2 weeks after the infusion operation. The others were killed 4 weeks after the operation. The whole mount of the basal membranes were directly observed under the fluorescence microscope for the expression of the EGFP (enhance green fluorescent protein) or for the expression of the hair cell specific marker and nuclear after staining with myosinVIIa rabbit polyclonal antibody and Dapi dye. Result:New cells with big nuclear, ellipse body and expressed with EGFP were found in the region near to the outmost row of the outer hair cells in 2 animal 2 weeks after the infusion. Moreover there were 3 animals with specific morphologic new cells in the location where ever been located by the outer hair cells and the region as 2 weeks animals 4 weeks after the infusion. Those cells were stained by myosinVIIa antibody. Conclusion: Atohl gene could transdifferent some supporting cells in the basal membrane into hair cell like cells in young adult guinea pigs in vivo. These supporting cells locate in the region of outer hair cells and the basal membrane which do not belong to the region of outer hair cells.%目的:在近成年豚鼠耳蜗内携带atoh1/EGFP基因的腺病毒是否能够将基膜上残留的支持细胞转分化为新的毛细胞.方法:选用体重在200~250g的健康花豚鼠12只,将构建同时表达atoh1和EGFP基因的E1/E3区缺失的人类免疫5型腺病毒5μl,通过耳蜗侧壁打孔灌注导入中阶内淋巴系统.其中6只于灌注2周后处死,6只灌注4周后处死,基膜铺片观察EGFP、毛细胞标记物myosinⅦa和Dapi

    This study investigated the effects of environmental enrichment on the cognitive performance of female conventional farm (growing) pigs in a spatial holeboard task. Ten pairs of littermates matched for weight were used. From each litter, one piglet was randomly assigned to a barren environment; the other was assigned to an enriched environment from 4 weeks of age. The enriched environment was double the size of the barren environment, had a floor covered with straw, a rooting area filled with peat, and one of the four different enrichment toys which were exchanged daily. Starting at 11 weeks of age, all pigs were tested in a spatial holeboard discrimination task in which 4 out of 16 holes were baited. Furthermore, basal salivary cortisol levels of all pigs were determined after the end of all testing. All pigs were able to acquire the pattern of baited holes (acquisition phase, 40 trials) and the diagonally mirrored pattern (reversal phase, 20 trials). During the acquisition phase, the reference memory performance of the enriched-housed pigs was better than that of their barren-housed littermates, i.e. they reduced visits to the unbaited set of holes. During the reversal phase, enriched-housed pigs had a better general working memory performance than the barren-housed pigs as indicated by reduced revisits to holes already visited during a trial, irrespective of whether they were of the baited or the unbaited set. The enriched-housed pigs also searched for the hidden bait faster during both phases. The environments did not affect basal salivary cortisol levels. In conclusion, environmental enrichment slightly improved the cognitive performance of pigs in a spatial learning task. We hypothesise that the long period of habituation to and testing in the holeboard acted as enrichment that partially reduced the effects of barren housing. PMID:26520648

    The biokinetics of polonium in nonhuman primates (Papio anubis) has been studied after intravenous injection of [sup 210]Po citrate. The urinary excretion of polonium in the baboon could be described by a single exponential function with a half-time of 15.6 days. Excretion fractions of polonium were found to be markedly different from those reported for other species, including humans. Polonium-210 was found to be distributed throughout the soft tissues of the baboon with 29% of the injected polonium being deposited in liver, 7% in kidneys and 0.6 in spleen. Retention of polonium in all tissues exhibited single exponential functions; however, the biological half-times were variable, ranging from 15 to 50 days. 23 refs., 9 figs., 10 tabs.

    Many cases of acne are hormonal in nature, meaning that 
they occur in adolescent girls and women and are aggravated 
by hormonal fluctuations such as those that occur during the menstrual cycle or in the setting of underlying hormonal imbalances as seen in polycystic ovary syndrome. For these patients, antihormonal therapy such as spironolactone is a valid and efficacious option. Herein, initiation and utilization of this medication is reviewed. PMID:27141564

    The 5 main physical manifestations of aged skin are wrinkles, uneven tone, brown spots, loss of elasticity, and dryness. One mechanism resulting in these physical manifestations is increased activity of the nuclear factor kappa B (NFκB) protein. This 12-week, double-blind, placebo-controlled, randomized split-face study compared the antiaging effect and safety of a face cream containing 4-Hexyl-1, 3-phenylenediol, an NFκB inhibitor, and ascorbic acid-2 glucoside versus placebo in adult females aged 45-70 years old. Subjects (n=42) applied active treatment or placebo to the same half face twice daily at home for 12 weeks. Clinical evaluation was carried out by a dermatologist. Subjects carried out similar self-grading assessments. Colorimetric measurements analyzed skin color, and biomechanical skin properties were evaluated. Clinical grading showed that most wrinkle parameters were significantly improved after 8 weeks of active treatment compared with baseline and placebo (P≤.05), with improvements maintained after 12 weeks. Only Marionette wrinkles did not show a significant improvement. Brown spots (color intensity/number), overall photodamage, and most complexion parameters improved significantly after 8 and 12 weeks compared with baseline and placebo (P≤.05). Self-grading yielded similar results compared with baseline. Self-grading did not demonstrate improvements with active treatment versus placebo, except for skin firmness at 8 and 12 weeks (P≤.05). A significant difference was seen with active treatment compared with placebo in all colorimetric parameters (L*, b*, and ITA°) after 8 weeks, and in spot coloration (b*) after 12 weeks (Pantiaging.

    Objective:To report detection of vestibular-evoked myogenic potentials (VEMPs) in the miniature pig. Methods:Potentials evoked by 1000 Hz tone bursts were recorded from neck extensor muscles and the masseter muscles in normal adult Bama miniature pigs anesthetized with 3%pentobarbital sodium and Carbachol II. Results:The latency of the first positive wave P from neck extensor muscles was 7.65 ± 0.64 ms, with an amplitude of 1.66 ± 0.34 uv and a rate of successful induction of 75%at 80 dB SPL. The latency of potentials evoked from the masseter muscles was 7.60 ± 0.78 ms, with an amplitude of 1.31 ± 0.28 uv and a rate successful induction of 66%at 80 dB SPL. Conclusion:The latencies and thresholds of VEMPs recorded from the neck extensor muscle and the masseter muscle appear to be comparable in normal adult Bama miniature pigs, although the amplitude recorded from the neck extensor muscle seems to be higher than that from the masseter muscle. However, because of their usually relatively superficial and easily accessible location, as well as their large volume and strong contractions, masseter muscles may be better target muscles for recording myogenic potentials.

  13. Of Domestic and Wild Guinea Pigs: Studies in Sociophysiology, Domestication, and Social Evolution

    Sachser, Norbert

    Among mammals a majority of each individual's daily expectations, motivations, and behaviors are directed to encounters with conspecifics. Therefore the knowledge of the genesis, control, and consequences of social interactions is crucial for understanding their social life. We present here our research on the sociophysiology, domestication, and social evolution of wild (Cavia aperea and Galea musteloides) and domestic (Cavia aperea f. porcellus) guinea pigs, which summarizes general rules for many group-living mammals. It is shown that social interactions have consequences not only for the individuals' reproductive success but also for their degrees of stress and welfare. The way in which individuals interact is controlled not only by the present environment but also by the previous social experiences which they have gathered during their behavioral development. Furthermore, the study of ontogeny does not begin at birth, because prenatal social factors acting on pregnant females can also affect the way in which the offspring will interact when adult. In addition, to understand the genesis of interactions between domesticated animals implies knowledge of the behavioral and physiological changes which occurred during the process of domestication. Finally, understanding the social interactions among individuals of the wild ancestor of the domesticated form requires knowledge of how their behavior patterns were brought about by natural selection during the process of social evolution.

    Tail lesions are associated with poor health either because they serve as a point of entry for pathogens or because of shared risk factors. This study investigated the relationship between carcass tail lesion and lung lesion severity scores in slaughter pigs. Carcasses were scored after scalding/dehairing for tail lesion severity (0-4). Lungs were scored according to an adapted version of the BPEX pig health scheme. Severity of enzootic pneumonia (EP-like lesions) was recorded on a scale of 0-50. Severity of pleurisy was scored on a 0-2 scale with score 2 equating to severe pleurisy or those lungs that remained attached to the chest wall ('lungs in chest'). The database for assessing pleurisy lesions contained all pleurisy scores (n=5628). Lungs with a score of 2 for pleurisy were excluded from the analysis of all other lung lesions as such lungs could not be assessed for other lesions (n=4491). Associations between tail lesions and different lung lesion outcomes were analysed using generalized linear mixed models (PROC GLIMMIX) with random effect for batch. Males were more affected by moderate (OR=1.9, 95% CI 1.51-2.34) and severe (OR=5.8, 95% CI 3.45-9.70) tail lesions than females. EP-like lesions and pleurisy were most commonly observed. Pigs with severe tail lesions tended to have more 'lungs in chest' than pigs with moderate tail lesions (P=0.1). No other associations between tail lesions and lung lesions were found. Males had higher odds of having EP-like lesions (OR=1.2, 95% CI 1.05-1.36) than females. Tail lesions on the carcass may not be an accurate predictor of lung health. However, tail lesions are important welfare indicators and respiratory disease is a significant infectious condition affecting pigs. Thus, recording of tail and lung lesions at meat inspection provides valuable information regarding on-farm health and welfare of pigs. PMID:27094136

    In mammals, damage to sensory receptor cells (hair cells) of the inner ear results in permanent sensorineural hearing loss. Here, we investigated whether postnatal mouse inner ear progenitor/stem cells (mIESCs) are viable after transplantation into the basal turns of neomycin-injured guinea pig cochleas. We also examined the effects of mIESC transplantation on auditory functions. Eight adult female Cavia porcellus guinea pigs (250-350 g) were deafened by intratympanic neomycin delivery. After 7 days, the animals were randomly divided in two groups. The study group (n=4) received transplantation of LacZ-positive mIESCs in culture medium into the scala tympani. The control group (n=4) received culture medium only. At 2 weeks after transplantation, functional analyses were performed by auditory brainstem response measurement, and the animals were sacrificed. The presence of mIESCs was evaluated by immunohistochemistry of sections of the cochlea from the study group. Non-parametric tests were used for statistical analysis of the data. Intratympanic neomycin delivery damaged hair cells and increased auditory thresholds prior to cell transplantation. There were no significant differences between auditory brainstem thresholds before and after transplantation in individual guinea pigs. Some mIESCs were observed in all scalae of the basal turns of the injured cochleas, and a proportion of these cells expressed the hair cell marker myosin VIIa. Some transplanted mIESCs engrafted in the cochlear basilar membrane. Our study demonstrates that transplanted cells survived and engrafted in the organ of Corti after cochleostomy. PMID:27007652

    Full Text Available This experiment was conducted to determine the requirement of available phosphorus (aP for pigs kept in hot environment. Seventy-two pigs (36 castrated males and 36 females with initial weight of 15.10±0.31 kg were allotted in a completely randomized block design with six treatments (0.107, 0.214, 0.321, 0.428, 0.535, and 0.642% of aP, six replicates and two pigs (1 castrated male and 1 female per experimental unit. Pigs were kept in a hot environment with temperature of 34.1±0.8 ºC. The levels of aP influenced the daily weight gain, which increased quadratically up to the estimated level of 0.477%, and feed conversion, which improved quadratically up to the estimated level of 0.457%. The levels of aP also influenced the content of phosphorus in the bone, which increased quadratically up to the estimated level of 0.529%. The available phosphorus requirement of 15- to 30-kg pigs kept in a hot environment, for the best results of daily weight gain, feed conversion and bone parameters are 0.477, 0.457, and 0.529%, corresponding to the estimated daily available phosphorus intakes of 4.75; 4.55 and 5.27 g, respectively.

    The purpose of this research was to identify pig welfare indicators that could help in recognizing stressful practices on farm. The study evaluated behavioral and physiological indicators (cortisol and negative acute phase proteins) in 2 groups of 20 female pigs 4 months old after a 48-hr transport. The first group (A) was transported at the end of May, the second (B) in June. Behavioral observations and blood collection occurred at arrival (D1) and 28 days later (D28). Compared with within-animal control samples obtained 28 days later, pigs of Group A had increased cortisol levels and decreased albumin concentrations after arrival. As demonstrated by lesion and behavior observations, the effect on cortisol and albumin was higher in Group B pigs after a tail-biting episode occurred. The study has reported no evidence of Retinol Binding Protein (RBP) in pigs. A method developed for swine RBP quantification found RBP strongly reduced in D28 samples of Group B, confirming it to be a negative protein in pigs. The suggested combination of physiological and behavioral indicators could provide useful information on the welfare state of an animal. PMID:18444023

    A more complicated pathology was observed in female pigs infected with Mycoplasma hyopneumoniae, when the same were exposed to 20 ppm dietary levels of fumonisin B1 (FB1) starting 14 days before infection for a period of 42 days as was assessed by gross pathology and pathomorphological examinations or computed tomography, and also manifested by the strong deterioration of the pneumonic process in two pigs and the subsequent euthanizing of one pig. Typical damages in FB1-fed pigs were a strong oedema in the lung and slight oedema in the other internal organs and mild degenerative changes in the kidneys, whereas the typical pathomorphological changes in M. hyopneumoniae-infected pigs corresponded to the morphologic pattern of a catarrhal bronchointerstitial pneumonia more pronounced in the cranial and middle lobes or in the cranial third of the caudal lobe of the lung. The pigs treated by both pathogens (toxic and infectious) revealed strong oedematous changes in the interstitium of lung in addition to deteriorated and extended bronchointerstitial pneumonic process.

  8. Catheterization of cerebral arteries under real-time MR imaging guidance: an experimental study in pigs

    International Nuclear Information System (INIS)

    Objective: To investigate the feasibility of catheterization of cerebral arteries under the real-time MR imaging guidance in experimental pigs. Methods: Ten small-sized female pigs were selected for this study. Via the femoral access, percutaneous catheterization with a 3 F active MR-tracking microcatheter was performed under real-time MRI guidance and the microcatheter was separately placed into bilateral ascending pharyngeal arteries. After the procedure, all the pigs were sacrificed and sent for pathologic examination. Gross pathologic examination of aortic arches, brachio-cephalic arteries, carotid arteries and ascending pharyngeal arteries was performed to search for the perforation and dissection. Results: MR angiography revealed that in pigs the bilateral ascending pharyngeal arteries formed an arteriolar network at the cranial base, supplying blood flow to the brain. Catheterization of ascending pharyngeal arteries from the femoral artery access was successfully performed in all 10 pigs with the help of real-time MR imaging-guidance. A single procedure took about 4-12 minutes. Macroscopically, no evidence of vascular injury of aortic arches, brachio-cephalic arteries, carotid arteries and ascending pharyngeal arteries was found. Conclusion: Under real-time MRI guidance the catheterization of cerebral arteries can be correctly and quickly accomplished in experimental pigs. (authors)

    Growing pigs can display undesirable behaviours, reflecting or causing poor welfare. Addition of magnesium (Mg) to the diet could reduce these, as Mg supplementation has been associated with improved coping ability in response to stress. This study examined the effect of supplementation with a Mg-rich marine extract-based product (Supplement) on the behaviour, skin and tail lesion scores and salivary cortisol concentrations of growing pigs. At weaning (28 days), 448 piglets were assigned to either Control or Supplement (0.05%) diets in single-sex groups of 14. Four weeks later (c. 17 kg), pigs were blocked according to weight and back test scores. Seven piglets from each pen were mixed with seven from another pen of the same sex and dietary treatment to yield the following groups: control male, Supplement male, control female and Supplement female (n = 4 of each). This marked the start of the 9-week experimental period. Instances of the following behaviours were recorded in each pen for 8 × 2 min periods 1 day/week: aggression (fight, head-knock and bite); harmful (tail-in-mouth, ear-chewing and belly-nosing); and sexual/mounting behaviour. Four focal pigs were selected from each pen, and their behaviour was continuously recorded for 2 × 5 min periods on the same day. Saliva was collected once per week at 1000 h by allowing pigs to chew on a cotton bud for c. 1 min. Salivary cortisol was analysed in duplicate by an enzyme immunoassay. Skin and tail lesions were scored according to severity 1 day/week. There were fewer aggressive incidents in Supplement pens (P pigs showed no treatment effect on the duration or incidence of aggressive behaviour. However, Supplement pigs spent less time performing harmful behaviours compared with control pigs (P tail-biting outbreaks or on tail lesion scores. However, Supplement females had lower skin lesion scores, in particular in the ears and shoulders (P pigs had lower salivary cortisol concentrations (P pigs, and therefore

    A study was conducted to evaluate the effect of 2 hulless barley varieties, with or without the addition of a nonstarch polysaccharide (NSP) enzyme complex (β-glucanase and xylanase), on growth performance of weaned piglets in a 42-d feeding study. The study was conducted with 140 piglets (PIC × Duroc). Pigs were allocated to pens (4 castrated males or 4 females per pen) based on BW and sex, and pens were assigned to 5 experimental diets with 4 pens of castrated males and 3 pens of females per treatment. Five isonitrogenous and isoenergetic diets were compared: 1) control corn-based diet (CTR), 2) diet with corn and wheat bran replaced by the Astartis hulless barley variety (AS), 3) diet with corn and wheat bran replaced by the AS supplemented with the NSP enzyme complex (ASE), 4) diet with corn and wheat bran replaced by the Alamo hulless barley variety (AL), and 5) diet with corn and wheat bran replaced by the AL supplemented with the NSP enzyme complex (ALE). The diets were formulated to meet or exceed nutrient requirements and offered in 2 phases: d 0 to 14 and d 14 to 42. At the end of the study, pigs fed AS and AL had equal weights as pigs fed CTR. Pigs fed the hulless barley diets had greater (P Pigs fed the ASE and ALE had greater (P pigs fed the AS than those fed the AL (barley × enzyme, P pigs fed the AS during the P2 and overall phase, but it had no effect on those fed the AL (barley × enzyme, P wheat bran in weaned pig diets. Addition of the NSP enzyme complex to AS variety, but not AL variety, improved growth performance of weanling pigs. PMID:24671580

  11. GRP nerves in pig antrum

    DEFF Research Database (Denmark)

    Holst, J J; Poulsen, Steen Seier

    We extracted gastrin-releasing peptide (GRP) and its C-terminal decapeptide corresponding to 6.4 and 6.8 pmol/g from pig antrum mucosa. By immunohistochemistry GRP was localized to mucosal, submucosal, and myenteric nerve fibers. A few nerve cell bodies were also identified. Using isolated perfused...... pig antrum with intact vagal innervation, we found concomitant, atropine-resistant release of GRP and gastrin during electrical stimulation of the vagal nerves. Intra-arterial GRP at 10(-11)-10(-10) mol/l caused up to fivefold, dose-dependent increases in gastrin secretion; higher doses were less...... response to GRP and abolished the effect of vagal stimulation. The available evidence strongly suggests that GRP nerves are responsible for the stimulatory vagal effects on gastrin secretion in the pig....

    Two experiments were performed to determine the anthelmintic effect of some phytogenic feed additives on a mild infection of Ascaris suum in growing and finishing pigs. Usually, an infection of A. suum is controlled by using conventional synthetic drugs. Organic farmers, however, prefer a non-pharmaceutical approach to worm control. Therefore, phytotherapy could be an appropriate alternative. In the first experiment, a commercial available organic starter diet was supplemented with 3% of a herb mixture, adding 1% Thymus vulgaris, 1% Melissa officinalis and 1% Echinacea purpurea to the diet, or with 4% of a herb mixture, thereby adding the mentioned herbs plus 1% Camellia sinensis (black tea). A negative control group (no treatment) and a positive control group (treatment with conventional synthetic drug flubendazole) were included. In the second experiment, the anthelmintic properties against A. suum of three individual herbs, Carica papaya, Peumus boldus and Artemisia vulgaris, each in a dose of 1%, were tested. Pigs were infected with 1000 infective worm eggs each. Each experiment was performed with 32 individually housed growing pigs (8 replicates/treatment), which were monitored for 67 days. It was hypothesized that the herbs would block the cycles of the larvae, thereby preventing the development of adult worms. Therefore, phytogenic feed additives were not supplied during the whole experimental period, but only from the start until D39. Pigs were inoculated with infective worm eggs during five consecutive days (D17-D21). At D67 all pigs were dissected, whereafter livers were checked for the presence of white spots. Also numbers of worms in the small intestine were counted. In experiment 1, the numbers of worm-infected pigs were similar for both the herb supplemented (groups 3 and 4) and the unsupplemented (group 1) treatments (5-6 pigs of 8), while the treatment with flubendazole (group 2) resulted in 0 infected pigs. In experiment 2, herb addition (groups 2

    High ambient temperature impacts feed intake, growth, and nutrient utilization in pigs. However, little is known on its effects on immune function and, therefore, on how or if it could modulate the utilization of nutrients in pigs exposed to an inflammatory challenge. The aim of this study was to evaluate the effects of high ambient temperature on energy and nitrogen utilization in pigs submitted to repeated injections of Escherichia coli lipopolysaccharide (LPS). Twenty-eight catheterized and pair-housed female pigs (55 kg BW) were assigned to 1 of the 2 thermal conditions: thermoneutrality (TN, 24°C) or high ambient temperature (HT, 30°C). Within each condition, pigs had a 2-wk adaptation period in climatic-controlled rooms and then were transferred to open-circuit respiration chambers. Pigs remained in respiration chambers for a period of 18 d, which was divided into a 7-d period without LPS (baseline) and a subsequent 11-d period with LPS administration (LPSperiod). The interaction between ambient temperature and period was not significant for most of the traits studied. At baseline, pigs kept at HT had lower ADFI (1,500 vs. 2,003 g/d; P thermic effect of feeding (P = 0.01) and resting HP (P < 0.01). In addition, the LPS induced a reduction in protein (P < 0.01) and fat deposition (P = 0.01) in pigs kept at TN (-79 and -73 g/d, respectively) and at HT (-41 and -44 g/d, respectively). In conclusion, our study confirms that high temperature reduces feed intake, growth performance, and HP. Moreover, our results evidence that irrespective of thermal condition, an inflammatory LPS challenge affects energy utilization through changes in ME intake and maintenance requirements.

  16. Late effects of radiation on the lumbar spinal cord of guinea pigs: Re-treatment tolerance

    International Nuclear Information System (INIS)

    Using a guinea pig model of lumbar myelopathy, various factors affecting the tolerance of spinal cord to irradiation were assessed: (a) extent of initial injury; (b) time interval between priming and test doses; and (c) animal age at the time of initial radiation treatment. A 3 cm section of lumbar spinal cord of guinea pigs was irradiated with fractionated doses of 4.5 Gy gamma rays given as 9 fractions per week. Guinea pigs were primed with 9 x 4.5 Gy in 7 days which is 60% of the ED50 for a continuous course of treatment. After 28 or 40 weeks, animal were retreated with 6-14 fractions of 4.5 Gy. Animals were observed for 2 years following the priming dose and both the incidence and latency of myelopathy recorded. Young adult guinea pigs (8 wk old) showed both a decreased radiation tolerance and latency compared to old individuals (40 wk old). At 28 or 40 wk after 9 x 4.5 Gy, only about 8% of the initial injury was remembered in young adult guinea pigs. The amount of residual injury was dependent on the initial damage as a proportion of the tolerance dose. The spinal cord shows a greater capacity for long-term recovery than generally appreciated and re-treatment doses clinically prescribed may be lower than necessary. 8 refs., 3 figs., 2 tabs
