The identities of the Brazilian female athlete: the "points of temporary attachment" of women in sports

The aim of this study is to analyze the formation of the Brazilian Olympic female athletes' identities and the construction of this social role both in the Olympic scene as in Brazilian social context. The results, when compared with previous researches and the theoretical approach allows to conclude that even after inclusion of the growing Brazilian women in several sports - including pointing out that this did not occur in the form of confrontation, just as in other countries - this does not represent a rethinking of the social roles of the female and male letting to the athletes maintain a separation between sports life and life as a woman.

Fall Armyworm, Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae), Female Moths Respond to Herbivore-Induced Corn Volatiles

In response to herbivore attack, plants release herbivore-induced plant volatiles (HIPVs) that represent important chemical cues for herbivore natural enemies. Additionally, HIPVs have been shown to mediate other ecological interactions with herbivores. Differently from natural enemies that are generally attracted to HIPVs, herbivores can be either attracted or repelled depending on several biological and ecological parameters. Our study aimed to assess the olfactory response of fall armyworm-mated female moths toward odors released by mechanically and herbivore-induced corn at different time intervals. Results showed that female moths strongly respond to corn volatiles, although fresh damaged corn odors (0-1 h) are not recognized by moths. Moreover, females preferred volatiles released by undamaged plant over herbivore-induced plants at 5-6 h. This preference for undamaged plants may reflect an adaptive strategy of moths to avoid competitors and natural enemies for their offspring. We discussed our results based on knowledge about corn volatile release pattern and raise possible explanations for fall armyworm moth behavior.

The sialotranscriptome of Antricola delacruzi female ticks is compatible with non-hematophagous behavior and an alternative source of food

The hosts for Antricola delacruzi ticks are insectivorous, cave-dwelling bats on which only larvae are found. The mouthparts of nymphal and adult A. delacruzi are compatible with scavenging feeding because the hypostome is small and toothless. How a single blood meal of a larva provides energy for several molts as well as for oviposition by females is not known. Adults of A. delacruzi possibly feed upon an unknown food source in bat guano, a substrate on which nymphal and adult stages are always found. Guano produced by insectivorous bats contains twice the amount of protein and 60 times the amount of iron as beef. In addition, bacteria and chitin-rich fungi proliferate on guano. Comparative data on the transcriptome of the salivary glands of A. delacruzi is nonexistent and would help to understand the physiological adaptations of salivary glands that accompany different sources of food as well as the steps taken by the Acari toward haematophagy, believed to have evolved from scavenging dead animals. Annotation of the transcriptome of salivary glands from female instars of A. delacruzi collected on guano categorized 5.7% of the clusters of expressed genes as putative secreted proteins. They included abundantly expressed TIL-domain-containing proteins (possible anti-microbials), an abundantly expressed protein similar to a serum amyloid found in the sialotranscriptomes of Ornithodoros spp., a savignygrin, a family of mucin/peritrophin/cuticle-like proteins, anti-microbials and an HIV envelope-like glycoprotein also found in soft ticks. When comparing the transcriptome of A. delacruzi with those of blood-feeding female soft and hard ticks some notable differences were observed; they consisted of the following transcripts over- or under-represented or absent in the sialotranscriptome of A. delacruzi that may reflect its source of food: ferritin, mucins with chitin-binding domains and TIL-domain-containing proteins versus lipocalins, basic tail proteins, metalloproteases, glycine-rich proteins and Kunitz protease inhibitors, respectively.

[Erytrogram of healthy female Holstein calves during the first month of life.] Eritrograma de bezerras sadias, da raca Holandesa, no primeiro mes de vida. Pesquisa Veterinaria Brasileira 32(4): 357-360. Departamento de Cl nica Medica, Faculdade de Medicina Veterinaria e Zootecnia, Universidade de Sao Paulo, Campus Universitario, Av. Prof. Dr. Orlando Marques de Paiva 87, Sao Paulo, SP 05508-000, Brazil. E-mail: febencli@usp.br In order to establish reference values, and to assess the in fluence of the age factor on the erytrogram of healthy Holstein calves, blood samples from 300 animals were used, spread over 15 experimental groups, according to age, in the first month of life. Variations of the average values for the components of erytrogram were as follows: number of red blood cells (x10(6)/mm(3)) = 6.68-7.60, packed cell volume (%) = 29.80-33.35, hemoglobin concentration (g/dl) = 9.00-10.43, mean corpuscular volume (fl) = 38.93-47.68, mean corpuscular hemoglobin (pg) = 11.75-14.69, mean corpuscular hemoglobin concentration (%) = 29.53-31.63% and number of reticulocytes (x10(3)/mm(3)) = 0.00-11.86. The in fluence of the age factor proved to be significant for the mean corpuscular volume, mean corpuscular hemoglobin and the number of reticulocytes.

EVALUATION OF THE PASSIVE RESISTIVE TORQUE IN FEMALE ATHLETES WITH ANKLE SPRAIN

Introduction: The ankle sprain is one of the most common injuries in athletes. Direct evaluation of the ligament laxity can be obtained through the objective measurement of extreme passive inversion and eversion movements, but there are few studies on the use of the evaluation of the passive resistive torque of the ankle to assess the capsule and ligaments resistance. Objective: The aim of this study was to compare the inversion and eversion passive torque in athletes with and without ankle sprains history. Method: 32 female basketball and volleyball athletes (16.06 +/- 0.8 years old; 67.63 +/- 8.17 kg; 177.8 +/- 6.47 cm) participated in this study. Their ankles were divided into two groups: control group (29), composed of symptom-free ankles, and ankle sprain group, composed of ankles which have suffered injury (29). The resistive torque at maximum passive ankle movement was measured by the isokinetic dynamometer and the muscular activity by electromyography system. The athletes performed 2 repetitions of inversion and eversion movement at 5, 10 and 20 degrees/s and the same protocol only at maximum inversion movement. Results: The resistive passive torque during the inversion and eversion was lower in the ankle sprain group. This group also showed lower torques at the maximum inversion movement. No differences were observed between inversion and eversion movement. Conclusions: Ankle sprain leads to lower passive torque, indicating reduction of the resistance of the lateral ankle ligaments and mechanical laxity.

X-linked adrenoleukodystrophy in heterozygous female patients: women are not just carriers

X-linked adrenoleukodystrophy (X-ALD) is a recessive X-linked disorder associated with marked phenotypic variability. Female carriers are commonly thought to be normal or only mildly affected, but their disease still needs to be better described and systematized. Objectives: To review and systematize the clinical features of heterozygous women followed in a Neurogenetics Clinic. Methods: We reviewed the clinical, biochemical, and neuroradiological data of all women known to have X-ADL. Results: The nine women identified were classified into three groups: with severe and aggressive diseases; with slowly progressive, spastic paraplegia; and with mildly decreased vibratory sensation, brisk reflexes, and no complaints. Many of these women did not have a known family history of X-ALD. Conclusions: Heterozygous women with X-ADL have a wide spectrum of clinical manifestations, ranging from mild to severe phenotypes.

Criminal career-related factors among female robbers in the State of Sao Paulo, Brazil, and a presumed 'revolving-door' situation

Introduction: Risk-taking behaviors, family criminality, poverty, and poor parenting have been frequently associated with an earlier onset of criminal activities and a longer criminal career among male convicts. Objective: This study aims to identify factors related to the onset and recurrence of criminal behavior among female robbers in the State of Sao Paulo - Brazil. Method: It was a cross-sectional study carried out inside a feminine penitentiary in Sao Paulo. From June 2006 to June 2010, 175 inmates convicted only for robbery were recruited to be evaluated about family antecedents of criminal conviction, alcohol and drug misuse, impulsiveness, depressive symptoms, and psychosocial features. Results: Having family antecedents of criminal conviction consistently predicted an earlier onset of criminal activities and a longer criminal career among female robbers. Drug use in youth and the severity of drug misuse were significantly related to the initiation and recurrence of criminal behavior, respectively. Discussion: Prisons must systematically screen detainees and provide treatments for those with health problems in general. Children of inmates should obtain help to modify the negative consequences of their parents' incarceration in order to mitigate the negative consequences of pursuing this 'static' factor.

Ultrastructural changes in the ovary cells of engorged Rhipicephalus sanguineus female ticks treated with esters of ricinoleic acid from castor oil (Ricinus communis)

Rhipicephalus sanguineus is a widely distributed tick species that has adapted to the urban environment, and the dog is its main host. This species is also known as a vector and reservoir of diseases caused by bacteria, protozoa, and viruses. Currently, acaricides of synthetic chemical origin have been widely and indiscriminately used, leading to the development of resistance to these products by ticks and causing damage to the environment. Thus, these issues have made it necessary to seek other forms of controlling these ectoparasites. R. sanguineus was artificially infested in host New Zealand White rabbits, which were divided into four treatment groups: control (CG1 and CG2) and treatment (TG1 and TG2) groups. TG1 and TG2 hosts were provided with feed supplemented with esters of ricinoleic acid from castor oil at a concentration of 5 g/kg of feed for 7 and 15 days. Afterward, the ovaries of the female ticks were removed for analysis by transmission electron microscopy. The results showed ultrastructural changes in the somatic and germ cells of ovaries from TG1 and TG2 females, particularly with respect to chorion deposition, a protective membrane of the oocyte, as well as in the transport process of vitellogenic materials via the hemolymph and pedicel cells. Moreover, the mitochondria were less electron-dense and had cristae that were more disorganized than the mitochondria from CG1 and CG2 individuals. Thus, this study demonstrated the action of esters on the ovaries of R. sanguineus, signaling the prospect of a way to control this ectoparasite without affecting nontarget organisms or the environment.

Female Sexual Function and Gestational Diabetes

Introduction. The number of women with gestational diabetes mellitus (GDM) is growing worldwide in parallel with the obesity epidemic. The diagnosis of GDM leads to substantial modifications in the daily routine of these women, and these adjustments could potentially affect their sexual function. There are no previous studies on the sexual function of patients with GDM. Aim. The aim of this study was to investigate the sexual function of patients with GDM in comparison with healthy pregnant women at the same gestational age. Methods. Brazilian women in the third trimester of pregnancy with and without GDM were invited to participate in this cross-sectional study while waiting for their antenatal care visits at a single public tertiary teaching institution between March and December 2010. The Brazilian version of the Female Sexual Function Index (FSFI) questionnaire was used to assess sexual function. Main Outcome Measures. Desire, arousal, lubrication, orgasm, sexual satisfaction, and pain during and after coitus in the last 4 weeks, measured according to a standardized and validated questionnaire. Results. A total of 87 participants were enrolled (43 healthy women and 44 with GDM). There were no significant differences in the sociodemographic characteristics of both groups. The total FSFI scores of GDM patients was 21.0 +/- 9.59 compared with 22.3 +/- 9.17 for healthy women (P = 0.523). Difficulty in desire was the most common sexual dysfunction symptom in both groups, being reported by 42% and 50% of GDM and healthy women, respectively (P = 0.585). Conclusion. The sexual function of Brazilian patients with GDM does not differ significantly from that of healthy pregnant women at the same gestational age.

Differences between female and male adolescents regarding individual vulnerability to HIV

The objective of this study was to comparatively analyze male and female adolescents' vulnerability to HIV/AIDS, based on their knowledge, values and practices. This is an exploratory-descriptive study, performed using a quantitative approach. The students answered a questionnaire from which relevant questions were selected for the analysis. The participants were 207 adolescents, 43.5% male and 56.5% female. Most adolescents report having initiated sexual activities. It was observed that the participants have knowledge deficits regarding HIV transmission and safe sexual practices. Although they report knowing about condom use as a method of protection against HIV, they do not always use them. It was observed that there are values connected to the representations of gender, but it is noticed there is an evolution regarding the autonomy and power of the girls' negotiation regarding condom use.

Postural control parameters in elderly female fallers and non-fallers diagnosed or not with knee osteoarthritis

Objectives: To compare stabilometric parameters of elderly female fallers and non-fallers associated or not with knee osteoarthritis (OA). Methods: Fifty-six elderly female fallers and non-fallers diagnosed or not with unilateral or bilateral knee OA were divided into the following groups: FOA (n = 10), elderly female falters with knee OA; FNOA (n = 11), elderly female fallers without knee OA; NFOA (n = 14), elderly female non-fallers with knee OA; and NFNOA (n = 21), elderly female non-fallers without knee OA. For analyzing semi-static balance on a force platform with the elderly females standing, the following parameters were assessed in four conditions: center of pressure (COP), anterior-posterior and mediolateral displacements (APD and MLD, respectively); and COP anterior-posterior and mediolateral displacement velocities (APV and MLV, respectively). The following conditions were assessed: 1) standing on a firm wooden surface with eyes open (WSEO); 2) standing on a firm wooden surface with eyes closed (WSEC); 3) standing on a foam surface with eyes open (FSEO); 4) standing on a foam surface with eyes closed (FSEC). Results: The elderly females with knee OA showed greater APD in all four conditions assessed (P < 0.05), while the elderly female fallers showed greater MLD (P < 0.05). No difference between the groups was observed for APV and MLV (P > 0.05). Conclusions: Knee OA per se increases APD of the COP, while the history of falls, regardless of the presence of knee OA, hinders postural control in the ML direction.

17 beta-Estradiol replacement in young, adult and middle-aged female ovariectomized rats promotes improvement of spatial reference memory and an antidepressant effect and alters monoamines and BDNF levels in memory- and depression-related brain areas

Clinical and experimental evidence suggest that estrogens have a major impact on cognition, presenting neurotrophic and neuroprotective actions in regions involved in such function. In opposite, some studies indicate that certain hormone therapy regimens may provoke detrimental effects over female cognitive and neurological function. Therefore, we decided to investigate how estrogen treatment would influence cognition and depression in different ages. For that matter, this study assessed the effects of chronic 17 beta-estradiol treatment over cognition and depressive-like behaviors of young (3 months old), adult (7 months old) and middle-aged (12 months old) reproductive female Wistar rats. These functions were also correlated with alterations in the serotonergic system, as well as hippocampal BDNF. 17 beta-Estradiol treatment did not influence animals' locomotor activity and exploratory behavior, but it was able to improve the performance of adult and middle-aged rats in the Morris water maze, the latter being more responsive to the treatment. Young and adult rats displayed decreased immobility time in the forced swimming test, suggesting an effect of 17 beta-estradiol also over such depressive-like behavior. This same test revealed increased swimming behavior, triggered by serotonergic pathway, in adult rats. Neurochemical evaluations indicated that 17 beta-estradiol treatment was able to increase serotonin turnover rate in the hippocampus of adult rats. Interestingly, estrogen treatment increased BDNF levels from animals of all ages. These findings support the notion that the beneficial effects of 17 beta-estradiol over spatial reference memory and depressive-like behavior are evident only when hormone therapy occurs at early ages and early stages of hormonal decline.

The effect of ploidy on the fatty acid profile during the reproductive cycle of female rainbow trout (Oncorhynchus mykiss)

Rainbow trout Oncorhynchus mykiss triploids are regularly produced in fish farms to improve growth because the triploid females do not develop ovaries during the reproductive cycle. In this study, the tissue fatty acid allocations in triploid and diploid females were compared during the reproductive cycle to determine whether the ploidy influences the fatty acid profile of fish produced in aquaculture. The ovaries, liver, and white muscle fatty acid contents of diploid and triploid females were analyzed during the reproductive cycle. Diploid females tend to accumulate more polyunsaturated fatty acids than triploids during some phases of the reproductive cycle, and this profile was compensated by an increase in saturated and monounsaturated fatty acids in triploid females. Arachidonic acid (C20:4n6) was the main n6 polyunsaturated fatty acid in the ovaries of diploid females during the most advanced phases of the reproductive cycle, and docosahexaenoic acid (C22:6n3) was the main n3 polyunsaturated fatty acid. In triploid females, the percentage of both of these polyunsaturated fatty acids was lower than in diploid females during the most advanced phases of the reproductive cycle. In general, the lack of ovary development altered the hepatic synthesis of some fatty acids, mainly monounsaturated and polyunsaturated fatty acids, decreasing the content of the main fatty acids in the white muscle and, consequently, the mobilization of these specific fatty acids to the ovaries.

Description of the female and new records of Triatoma baratai Carcavallo & Jurberg, 2000 (Hemiptera: Heteroptera: Reduviidae: Triatominae) from Mato Grosso do Sul, Brazil, with a key to the species of the Triatoma matogrossensis subcomplex

Triatoma baratai Carcavallo & Jurberg, 2000, a species similar to Triatoma williami Galvao, Souza & Lima, 1967 and belonging to the T. matogrossensis subcomplex, was described based on a male specimen collected in a sylvatic environment, near a cave, in Bonito county, Bodoquena mountain range, state of Mato Grosso do Sul, Brazil. In the present work we describe the female of T. baratai, captured in a chicken house, in Nioaque county, state of Mato Grosso do Sul, Brazil. Furthermore, we recorded the occurrence of T. baratai in domiciles and peridomestic environment in another four municipalities (Bodoquena, Bela Vista, Corumba, and Miranda), extending its geographical distribution. Finally, we present a key to the species of the Triatoma matogrossensis subcomplex.

Disparities in female breast cancer mortality rates in Brazil between 1980 and 2009

OBJECTIVE: To describe the temporal trends in female breast cancer mortality rates in Brazil in its macro-regions and states between 1980 and 2009. METHODS: This was an ecological time-series study using data on breast cancer deaths registered in the Mortality Data System (SIM/WHO) and census data on the resident population collected by the Brazilian Institute of Geography and Statistics (IBGE/WHO). Joinpoint regression analyses were used to identify the significant changes in trends and to estimate the annual percentage change (APC) in mortality rates. RESULTS: Female breast cancer mortality rates in Brazil tended to stabilize from 1994 onward (APC = 0.4%). Considering the Brazilian macro-regions, the annual mortality rates decreased in the Southeast, stabilized in the South and increased in the Northeast, North, and Midwest. Only the states of Sao Paulo (APC = -1.9%), Rio Grande do Sul (APC = -0.8%) and Rio de Janeiro (APC = -0.6%) presented a significant decline in mortality rates. The greatest increases were found in Maranhao (APC = 12%), Paraiba (APC = 11.9%), and Piaui (APC = 10.9%). CONCLUSION: Although there has been a trend toward stabilization in female breast cancer mortality rates in Brazil, when the mortality rate of each macro-region and state is analyzed individually, considerable inequalities are found, with rate decline or stabilization in states with higher socioeconomic levels and a substantial increase in those with lower socioeconomic levels.
