RESUMO
In Brazil, acanthocephalans parasitise anurans in several biomes. In the present study, we performed an analysis of acanthocephalan infections across 175 anuran individuals from the Cerrado biome, belonging to ten species: Boana raniceps, Pithecopus hypochondrialis, Scinax fuscomarginatus, Scinax x-signatus, Leptodactylus pustulatus, Leptodactylus macrosternum, Leptodactylus vastus, Physalaemus cuvieri, Adenomera hylaedactyla, and Elachistocleis piauiensis. We also verified the specificity of the parasites using the STD* index. Additionally, we conducted a survey of acanthocephalan infection in anurans in South America. The studied assemblage in the Brazilian Cerrado presented 57 parasitised hosts of 175 specimens (overall prevalence: 32.6%). In total, 437 acanthocephalans cystacanths were recorded, among which 286 presented the same morphotype but could not be identified, 148 belonged to the genus Centrorhynchus, and three belonged to Oncicola. Unidentified acanthocephalans had a higher prevalence in L. vastus (53.85%) and the highest intensity was in L. pustulatus (17±16). The highest prevalence of Centrorhynchus sp. was in the species S. fuscomarginatus (28.57%), while the highest intensity was observed in L. vastus (111). The taxon Oncicola sp. it had a prevalence of 3.23% and an intensity of 3 only in S. x-signatus. The highest specificity was recorded for Oncicola sp. (STD*= 1), whereas the lowest was found in Centrorhynchus sp. (STD*= 2.21). Finally, according to the survey for South America, we found ten records of acanthocephalan taxa parasitizing 58 species of anurans distributed in seven countries (Brazil with the most records).

BACKGROUND: Haplotypes of adiponectin gene single nucleotide polymorphisms (SNP) might be related to metabolic disorders. AIM: To assess whether the prevalence of SNP 45T/G and 276G/T of the adiponectin gene and their haplotypes differ between polycystic ovary syndrome (PCOS) and non-hirsute cycling controls and to investigate the relationship between these haplotypes and risk factors for cardiovascular disease. SUBJECTS AND METHODS: In this case-control study, 80 women with PCOS and 1500 non-hirsute controls with regular cycles underwent clinical and laboratory measurements. Genotype distribution was analyzed by conventional PCR-restriction fragment length polymorphism. RESULTS: Compared to controls, PCOS women had greater body mass index (BMI) (31.0±7.9 kg/m² vs 23.4±4.6 kg/m²; p<0.001), waist circumference (92.2±18.8 cm vs 74.5±10.2 cm; p<0.001), and systolic and diastolic blood pressure (124.6±19.9 vs 111.5±13.0 mmHg and 79.2±12.5 vs 71.8±10.6 mmHg; p<0.025), as well as a worse lipid profile (p<0.007), even after adjustment for age and BMI. Genotype distribution was similar in PCOS and controls (45T/G: p=0.399; 276G/T: p=0.135). Six haplotypes were inferred and their frequencies differed significantly between the groups (p=0.001). The TGTG haplotype was more frequent in PCOS than controls (41.3 vs 18.9%). In PCOS, the GG genotype for SNP 276 (p=0.031) and the TGTG haplotype (p=0.023) were associated with higher systolic blood pressure vs other genotypes and haplotypes. Body composition, glucose, insulin, and lipid profile were similar across genotypes and haplotypes in both groups. CONCLUSIONS: Haplotype TGTG from adiponectin gene variants 45T/G and 276G/T is related to susceptibility to PCOS, and might be associated with increased blood pressure in PCOS.

BACKGROUND: Evidence suggests that precocious pubarche (PP) girls may have higher risk of developing polycystic ovary syndrome (PCOS) at later ages. Vitamin D receptor (VDR) gene polymorphisms have been implicated in the risk of diabetes and PCOS, but little is known about the role of VDR in PP. AIM: To assess the frequencies of VDR gene ApaI, TaqI, BsmI, and FokI polymorphisms and to determine whether these variants are associated with sex hormone concentrations in patients with PP and controls from southern Brazil. SUBJECTS AND METHODS: Blood was collected from 36 girls with PP and 197 controls for genotyping of BsmI and FokI polymorphisms using real-time PCR and of ApaI e TaqI polymorphisms using restriction fragment length polymorphism. Hormone levels were also determined. RESULTS: Genotype GG of the ApaI single nucleotide polymorphism (SNP) was more frequent in PP (30.6%) than in controls (16.2%) [odds ratio (OR): 2.269; confidence interval 95% (95%CI): 1.015-5.076; p=0.042]. This genotype was also associated with lower estradiol [35.30 (14.80-50.48) pg/ml vs 12.22 (6.49-23.69) pg/ml; p=0.025] and total testosterone levels (0.52 (0.39-0.84) ng/ml vs 0.20 (0.11-0.47) ng/ml; p=0.005) as compared with the TT + TG genotypes in girls with PP. The distribution of TaqI, BsmI, and Fokl SNP was similar in PP and controls, and no association was found between these polymorphisms and sex steroid levels. CONCLUSIONS: The ApaI SNP of the VDR gene was associated with PP in the studied population and may modulate ovarian steroid secretion in these girls.

In this study was evaluated the influence of glutamine supplementation on the endogenous content of amino acids, proteins, total phenolics, flavonoids and proanthocyanidins in Bacupari callus. The explants were inoculated in MS medium, MS with half concentration of the nitrogen salts (MS½) and nitrogen-free MS, supplemented with glutamine (5, 10, 30 and 60mM) named as Gln5, Gln10, Gln30 and Gln60. Amino acids and proteins were analyzed after 20, 80 and 140 days and the secondary metabolites on the 140th day. There was no difference in the amino acids on the 20th day. On the 80th day the treatments MS and MS½ presented the lowest levels. On the 140th day MS and MS½ presented the lowest amino acid concentration and Gln10 the highest. Concerning proteins, there was difference only on the 140th day, being the highest concentrations observed in Gln5, and the lowest in MS½ treatment. Total phenolics content was higher in the treatment Gln60 and lowest in MS. Treatments Gln5, Gln10, Gln30 and MS½ were statistically equal. For flavonoids, the highest values occurred in the treatments Gln30, Gln60 and MS½ and the lowest in Gln5, Gln10 and MS. Similarly, for the proanthocyanidins the highest concentrations were observed in treatment Gln60 and the lowest in Gln5 and MS. In conclusion, the treatment with 60mM of glutamine favors the protein accumulation and production of secondary metabolites in Bacupari callus.

Some macrophytes species show a high growth potential, colonizing large areas on aquatic environments. Cattail (Typha angustifolia L.) uncontrolled growth causes several problems to human activities and local biodiversity, but this also may lead to competition and further problems for this species itself. Thus, the objective of this study was to investigate anatomical modifications on T. angustifolia plants from different population densities, once it can help to understand its biology. Roots and leaves were collected from natural populations growing under high and low densities. These plant materials were fixed and submitted to usual plant microtechnique procedures. Slides were observed and photographed under light microscopy and images were analyzed in the UTHSCSA-Imagetool software. The experimental design was completely randomized with two treatments and ten replicates, data were submitted to one-way ANOVA and Scott-Knott test at p<0.05. Leaves from low density populations showed higher stomatal density and index. These modifications on stomatal characteristics were more evident on the leaf abaxial surface. Plants from low density populations showed thicker mesophyll and higher proportion of aerenchymal area. Roots from low density populations showed a higher proportion of the vascular cylinder. Whereas, plants from higher density populations showed greater thickness of the endodermis, exodermis, phloem and root cortex. Higher density populations showed a higher proportion of aerenchymal gaps in the root cortex. Therefore, cattail plants from populations growing under high density population show anatomical traits typical of plants under stress, which promotes the development of less functional anatomical modifications to aquatic environments.

Androgens may directly modulate early ovarian follicular development in preantral stages and androgen excess before puberty may disrupt this physiological process. Therefore, the aim of this study was to investigate the dynamics of follicular morphology and circulating androgen and estradiol levels in prepubertal Wistar rats acutely exposed to androgens. Prepubertal female Wistar rats were distributed into three groups: control, equine chorionic gonadotropin (eCG) intervention and eCG plus dehydroepiandrosterone (DHEA) intervention (eCG+DHEA). Serum DHEA, testosterone and estradiol levels were determined, and ovarian morphology and morphometry were assessed. The eCG+DHEA group presented increased serum estradiol and testosterone levels as compared with the control group (P<0.01), and higher serum DHEA concentration v. the eCG-only and control groups (P<0.01). In addition, the eCG+DHEA group had a higher number of, and larger-sized, primary and secondary follicles as compared with the control group (P<0.05). The eCG group presented intermediate values for number and size of primary and secondary follicles, without significant differences as compared with the other two groups. The number of antral follicles was higher in the eCG+DHEA and eCG groups v. controls (P<0.05). The number of primordial, atretic and cystic follicles were similar in all groups. In conclusion, the present experimental model using an acute eCG+DHEA intervention was useful to investigate events involved in initial follicular development under hyperandrogenic conditions, and could provide a reliable tool to study defective follicular development with possible deleterious reproductive consequences later in life.

BACKGROUND: The 2NN Study was a randomised comparison of the non-nucleoside reverse-transcriptase inhibitors (NNRTI) nevirapine and efavirenz. METHODS: In this multicentre, open-label, randomised trial, 1216 antiretroviral-therapy-naive patients were assigned nevirapine 400 mg once daily, nevirapine 200 mg twice daily, efavirenz 600 mg once daily, or nevirapine (400 mg) and efavirenz (800 mg) once daily, plus stavudine and lamivudine, for 48 weeks. The primary endpoint was the proportion of patients with treatment failure (less than 1 log(10) decline in plasma HIV-1 RNA in the first 12 weeks or two consecutive measurements of more than 50 copies per mL from week 24 onwards, disease progression [new Centers for Disease Control and Prevention grade C event or death], or change of allocated treatment). Analyses were by intention to treat. FINDINGS: Treatment failure occurred in 96 (43.6%) of 220 patients assigned nevirapine once daily, 169 (43.7%) of 387 assigned nevirapine twice daily, 151 (37.8%) of 400 assigned efavirenz, and 111 (53.1%) of 209 assigned nevirapine plus efavirenz. The difference between nevirapine twice daily and efavirenz was 5.9% (95% CI -0.9 to 12.8). There were no significant differences among the study groups in the proportions with plasma HIV-1 RNA concentrations below 50 copies per mL at week 48 (p=0.193) or the increases in CD4-positive cells (p=0.800). Nevirapine plus efavirenz was associated with the highest frequency of clinical adverse events, and nevirapine once daily with significantly more hepatobiliary laboratory toxicities than efavirenz. Of 25 observed deaths, two were attributed to nevirapine. INTERPRETATION: Antiretroviral therapy with nevirapine or efavirenz showed similar efficacy, so triple-drug regimens with either NNRTI are valid for first-line treatment. There are, however, differences in safety profiles. Combination of nevirapine and efavirenz did not improve efficacy but caused more adverse events.

In order to describe the changing patterns of risk factors for HIV-1 transmission of patients using hospital services at an AIDS referral centre in Porto Alegre, southern Brazil, data on demographic characteristics, referral patterns and risk factors at time of first presentation were collected prospectively on 405 patients between October 1985 and September 1991. Overall HIV-related patient workload increased during the study period, as did the proportion of infected female patients seen (P < 0.05). Of all patients, 147 (36%) presented with symptomatic HIV disease and 77 (19%) presented with an AIDS defining condition; men were more likely to present with symptomatic disease than women. Approximately 156 (44%) of men were self-referred compared with 4 (8%) of the women (P < 0.0001). Of the 357 infected men, 82 (23%) were bisexuals; of the 26 heterosexually infected women, 7 (24%) had bisexual male partners. These data suggest the increasing importance of heterosexual HIV transmission in this hitherto 'low' prevalence area, with male bisexuals constituting an important route through which heterosexual females are being infected in this area. The data also suggest that heterosexual women in Southern Brazil do not perceive themselves to be at risk for HIV-1 infection.
PIP: Unprotected homosexual intercourse and IV drug use were originally described as the predominant routes of HIV transmission in South America. Recent data, however, indicate that heterosexual transmission is becoming increasingly important in the region. With the goal of describing the changing patterns of risk factors for HIV-1 transmission, the authors collected prospectively data on demographic characteristics, referral patterns, and risk factors of patients at the time of first presentation to hospital services at an AIDS referral center in Porto Alegre, southern Brazil. The 357 male and 48 female patients presented over the period October 1985-September 1991. The overall HIV-related patient workload increased during the study period, as did the proportion of infected female patients. 44% of the men and 8% of women were self-referred. 36% of patients presented with symptomatic HIV disease and 19% with an AIDS-defining condition, with the men more likely than women to present with symptomatic disease. 23% of the infected men were bisexual; 24% of the heterosexually infected women had bisexual male partners. These findings suggest the importance of heterosexual HIV transmission in this area, with male bisexuals serving as an important route through which heterosexual females are being infected in the area. The data also suggest that heterosexual women in southern Brazil do not perceive themselves as being at risk for HIV-1 infection.

We determined the genotypes of the alcohol dehydrogenase (ALDH) and aldehyde dehydrogenase (ALDH2) loci of different ethnic groups living in Brazil, using saliva DNA amplified by PCR and allele-specific oligonucleotides. Self-reports of flushing reaction after drinking were also studied. The allelic frequencies of ADH2 and ALDH2 were found to be lower than those reported other authors, which might be a result of the admixture origin of the Brazilian population. Variability in facial flushing reaction suggests that other factors play a role in the expression of alcohol-induced flushing.

Self reports of flushing reaction after drinking, cutaneous sensitivity to alcohol (patch test), and genotypic determination of ADH2, ADH3, and ALDH2 were studied in 53 Brazilian volunteers of different ethnic groups. Genotypes were determined using single-strand conformation polymorphism in discontinuous buffer electrophoresis. Analysis of the results indicated several cases of a reported flushing reaction among ALDH2 1/1 individuals, while all but 2 cases of ALDH2 heterozygotes reported a flushing reaction. The latter subjects also had a negative result in the patch test. These preliminary results indicate that variability in the facial flushing reaction to alcohol seems to be a phenomenon resulting not only from the presence of a deficient ALDH2*2 allele, but also from other polymorphisms of alcohol-metabolizing enzymes.

It has been suggested that exposure to the elevated plus-maze (EPM) apparatus induces antinociceptive effects in mice as measured by the tail-flick assay, which are not blocked by the opiate antagonist naltrexone. The present study performed on 3-month old male EPM-M1 albino mice (12-14 animals per group) was designed to assess a) if exposure limited to the open or to the enclosed arm of the EPM would alter this effect; b) whether or not pharmacologically induced anxiety (1.0 mg/kg pentylenetetrazole, PTZ) would also reduce nociception; c) if exposure to the EPM would alter visceral pain, as measured by the abdominal contortion test. The simultaneous exposure to both the open and enclosed arms of the EPM, but not the exposure limited to each type of arm, led to statistically significant increases in tail withdrawal latencies (TWL). Indeed, 10 min after exposure to both arms, TWL values (mean +/- SEM) were 10.31 +/- 0.87 s as compared to a baseline value of 5.46 +/- 0.53 s. The acute administration of PTZ significantly increased TWL. Conversely, EPM-induced antinociception was not detected by the abdominal contortion test. These results confirm the existence of EPM-induced antinociceptive effects demonstrated by others and show that they may be influenced by multiple determinants.

The effects of nutritional copper deficiency on weight gain, food intake and fertility of pregnant and non-pregnant adult Wistar rats, and weight of newborns, were studied. The adult animals were subjected to diets with different copper content (control-5 ppm; moderate deficiency -1.2 ppm; severe deficiency -0.3 ppm) for six weeks (non-pregnant) and nine weeks (pregnant). No effect on weight gain or appetite was seen in the groups of animals subjected to copper deficiency. Fertility, as evaluated by the number of conceptuses and liverborns of the pregnant animals, and weight of newborns also, were not impaired. These data show that not only the extent of deficiency, but also the period during which it is imposed, as well as its duration, condition the appearance of alterations of this deficiency.

It approaches the influences of family relationship in the construction of the gender identity process, through the Theory of Objectal Relationship referential, proposed by Chorodow (1979). This theoretical support, emphasizes that the gender identity is basically influenced by the primary bonds established between child and adults, through the continuous personal relationship developing mother and father role. It points out that the gender construction for the boy and for the girl happens in a different way. It concludes pointing out some lines to be adopted by the nurse in the practice with families, as well as, some limitation of the Theory of Objectal Relationship.

Abstract In this study was evaluated the influence of glutamine supplementation on the endogenous content of amino acids, proteins, total phenolics, flavonoids and proanthocyanidins in Bacupari callus. The explants were inoculated in MS medium, MS with half concentration of the nitrogen salts (MS½) and nitrogen-free MS, supplemented with glutamine (5, 10, 30 and 60mM) named as Gln5, Gln10, Gln30 and Gln60. Amino acids and proteins were analyzed after 20, 80 and 140 days and the secondary metabolites on the 140th day. There was no difference in the amino acids on the 20th day. On the 80th day the treatments MS and MS½ presented the lowest levels. On the 140th day MS and MS½ presented the lowest amino acid concentration and Gln10 the highest. Concerning proteins, there was difference only on the 140th day, being the highest concentrations observed in Gln5, and the lowest in MS½ treatment. Total phenolics content was higher in the treatment Gln60 and lowest in MS. Treatments Gln5, Gln10, Gln30 and MS½ were statistically equal. For flavonoids, the highest values occurred in the treatments Gln30, Gln60 and MS½ and the lowest in Gln5, Gln10 and MS. Similarly, for the proanthocyanidins the highest concentrations were observed in treatment Gln60 and the lowest in Gln5 and MS. In conclusion, the treatment with 60mM of glutamine favors the protein accumulation and production of secondary metabolites in Bacupari callus.

Os explantes foram inoculados em meio MS, meio MS com metade da concentração de dos sais de nitrogênio (MS½) e meio MS sem nitrogênio suplementado com glutamina (5, 10, 30 e 60mM) denominados como Gln5, Gln10, Gln30 e Gln60. Os aminoácidos e as proteínas foram analisados após 20, 80 e 140 dias e os metabólitos secundários no 140° dia. Não houve diferença nos aminoácidos no 20° dia. No 80° dia os tratamentos MS e MS½ apresentaram os menores níveis. No 140° dia, MS e MS½ apresentaram as menores concentrações de aminoácidos e o Gln10 as maiores. A respeito das proteínas, houve diferença apenas no 140° dia, sendo as maiores concentrações observadas nos tratamentos Gln, e as menores no MS½. O conteúdo de fenólicos totais foi maior no tratamento Gln60 e menor no MS. Os tratamentos Gln5, Gln10, Gln30 e MS½ foram estatisticamente iguais. Para os flavonóides, os maiores valores ocorreram nos tratamentos Gln30, Gln60 e MS½ e os menores no Gln5, Gln10 e MS. Da mesma forma, para as proantocianidinas, as maiores concentrações foram observadas no tratamento Gln60 os menores no Gln5 e MS. Em conclusão, o tratamento com 60 mM de glutamina favorece o acúmulo de proteínas e a produção de metabólitos secundários em calos de Bacupari.
