Accessing the taxonomy of fish is a basic condition for the conservation of species, and the understanding of their evolutionary relationships. Many Neotropical species of fishes of the order Characiformes are considered incertae sedis because of a lack of consistent evidence of monophyly, with the genus Astyanax among them. With a cytotaxonomic and evolutionary purpose, we compared the karyotype of two species of Astyanax: Astyanax paranae and Astyanax elachylepis. Conventional cytogenetic analyses revealed 2n = 50 chromosomes for the two species, with interspecific and interpopulation karyotype variations. Heterochromatin was primarily localized in the pericentromeric regions, and it was associated with organized regions of the nucleolus (NORs) and/or telomeric regions in some acrocentric chromosomes. The in situ localization of 18S ribosomal DNA (rDNA) and 5S probes varied among A. paranae populations. In A. elachylepis, only one chromosome pair was stained by the 18S probe and another by the 5S probe, confirming a simple NORs pattern. These results support the utility of chromosome markers in Astyanax taxonomy and reveal the conserved characteristics of the karyotype of A. elachylepis, consisting exclusively of two chromosome arms, and the occurrence of simple homologous and non-syntenic sites for 18S and 5S rDNA in this species. © Mary Ann Liebert, Inc. 2016.

Objectives: To identify the difficulties on the family relationships and at work derived from the menopause symptoms, as well as the management measures adopted. Methods: Cross-sectional, qualitative/quantitative study attended by 30 post-menopause women. Results: The menopause related experiences were heterogeneous and not necessarily negative. There was great diversity in how the respondents defined menopause and only 33.3% had been prepared to experience it, mostly by medical directions. The first symptoms occurred at 46.5 years (± 5.3 years), being mentioned: the hot flashes, the gain of weight, the irritability and the pain during intercourse. There were differences between women in the number of symptoms perceived, ranging from 1 to 27 (13.4 ± 6.3). Important behavioral changes were mentioned such as the reduction of sexual activity due to the decline of libido, the lack of patience to deal with the sons, the less motivation to work and the reduced self-esteem. In order to deal with the symptoms they adopted new diets, physical exercises or altered some values and attitudes. Conclusions: The lack of preparation can lead to difficulties to cope with climacteric syndrome, which may compromise quality of life and/or personal satisfaction. © 2015 Sociedade Brasileira de Reprodução Humana.

Some herbicides are suspected of promoting teratogenic, carcinogenic and mutagenic events. Detection of induced mitotic crossing-over has proven to be an indirect way of testing the carcinogenic properties of suspicious substances, because mitotic crossing-over is involved in the multistep process of carcinogenesis. We examined mitotic crossing-over induced by two commercial herbicides (diuron and trifluralin) in diploid strains of Aspergillus nidulans based on the homozygotization index. Low doses (2.5 μg/mL) of diuron were sufficient to increase the mean homozygotization index in 2.1 and 11.3 times for UT448// UT196 and Dp II-I//UT196, respectively, whereas the same dose of tri-fluralin increased this mean only 1.2 (UT448//UT196) and 3.5 (Dp II-I// UT196) times, respectively. The lower homozygotization index value found for trifluralin could be due to its interference with mitotic crossingover in eukaryotic cells. We concluded that the diploid Dp II-I//UT196 of A. nidulans is more sensitive to organic compounds than UT448//UT196; these compounds cause recombinational events at a greater frequency in the latter diploid. This system holds promise as an initial test for carcinogenicity of organic compounds, including herbicides.

Background: The Flutter®VRP1 combines high frequency oscillation and positive expiratory pressure (PEP). Objective: To separately evaluate the effect of the Flutter®VRP1 components (high frequency oscillation and PEP) on mucus transportability in patients with bronchiectasis. Methods: Eighteen patients with bronchiectasis received sessions with the Flutter®VRP1 or PEP for 30 min daily in a randomized, crossover study. The treatment duration was four weeks with one of the therapies, one week of a "wash-out" period and followed by four more weeks with the other treatment. Weekly secretion samples were collected and evaluated for mucociliary relative transport velocity (RTV), displacement in a simulated cough machine (SCM) and contact angle measurement (CAM). For the proposed comparisons, a linear regression model was used with mixed effects with a significance level of 5%. Results: The Flutter®VRP1 treatment resulted in greater displacement in SCM and lower CAM when comparing results from the first (9.6 ± 3.4 cm and 29.4 ± 5.7°, respectively) and fourth weeks of treatment (12.44 ± 10.5 cm and 23.28 ± 6.2°, respectively; p < 0.05). There was no significant difference in the RTV between the treatment weeks for either the Flutter®VRP1 or PEP. Conclusion: The use of the Flutter®VRP1 for four weeks is capable of altering the respiratory secretion transport properties, and this alteration is related to the high frequency oscillation component. © 2011 Elsevier Ltd.

Background: The chronic venous insufficiency has a considerable socioeconomic impact in western countries because of high prevalence, treatment and research cost, and loss of days worked. The health survey questionnaire Short Form Health Survey (SF36), as well as the analysis of muscle activation and mobility of tibiotarsus' articulation, is an instrument used to its valuation. Objective: To evaluate the osteomuscular limitations and changes in life quality in bearers of venous ulcers in lower members. Methods: Ten patients with ulcers classified as CEAP (Clinic, Etiologic, Anatomic and Fisiopatologic) 6 were studied. They answered the SF-36 questionnaire and visual analogue pain and performed goniometry, muscular strength and electromyography. Results: The average age of the group studied was 67.4 (±11.7), being 70% of the cases female. There wasn't correlation statistically significant between pain, range of motion (ROM) muscular strength, electromyography (EMG) and the injury size. However, there was found correlation between the psychological profile of SF36 and the domain of motor activities, as well the psychological profile with social activities and the perception of itself. In studied muscles electromyographyc evaluation, was found significance too. Conclusion: The presence of venous ulcers in lower members can generate limitations and changes in the life quality of these people. The psychosocial aspect showed up preponderant over the motor aspect, increasing the restrictions in day life activities.

Brucellosis is a zoonotic disease with common agent is Brucella abortus in bovine specie. The disease in bulls is usually asymptomatic and could have absence of anti-B. abortus antibody in serum. It was investigated of the occurrence of bovine brucellosis in bulls, which involved testing blood serum and seminal plasma from 177 bulls used for natural mating or as semen donors. Blood was collected from all the animals by venipuncture of the jugular vein to obtain the serum samples, while seminal plasma was obtained from the animals by electroejaculation. Samples were tested in a screening test (rose bengal test). In the second stage, the samples testing positive in the RBT were subjected to the confirmatory test (2-mercaptoethanol). None of the animals tested positive when blood serum was used. However, 5.06% of the bulls were considered reagent positive when seminal plasma was tested. It also sought to determine whether there was an association between the kind of production and the destination of animals with positive results. The calculated odds ratio indicated that bulls of the kind of production dairy/both (beef and dairy) had a higher risk of brucellosis infection. It is recommended that seminal plasma agglutination and seroagglutination techniques are applied concomitantly.

The scope of this research, carried out together with community-based health workers (ACS) was: (1) to evaluate the mental health of the ACS; (2) to describe the vital events in the last year of the ACS; (3) to inquire about the level of anxiety of the ACS; (4) to correlate mental health, vital events and anxiety of the ACS. Participants: 116 ACS. Measurements: socio-demographic questionnaire, Goldberg General Health Questionnaire, The Life Events Inventory, State-Trait Anxiety Inventory. The majority of the ACS presented a moderate degree of anxiety and positive mental health; they reported having experienced few stressful events in the past year, even though the majority had experienced health problems. The fact that most of the ACS reported having experienced moderate anxiety levels suggests a probable interference of specific characteristics of the profession. However, the fact that the persons subjectively identified the presence of anxiety and classified it at a given level presupposes that they are using control strategies, which is a factor that assists in maintaining mental health.

Objective: To characterize and compare the in vitro transport properties of respiratory mucoid secretion in individuals with no lung disease and in stable patients with chronic obstructive pulmonary disease (COPD) and bronchiectasis. Methodology: Samples of mucus were collected from 21 volunteers presenting no lung disease who had undergone surgery, from 10 patients presenting chronic COPD, and from 16 patients with bronchiectasis. Mucociliary transport (MCT), transport by cough (SCM), and contact angle (CAM) were evaluated. Results: MCT was found to be greater in healthy individuals (1.0 ± 0.19) than in COPD (0.91 ±0.17) and bronchiectasis (0.76±0.23) patients (p<0.05), whereas SCM was greater in COPD patients (16.31 ±7.35cm) than in patients with bronchiectasis (12.16±6.64cm) and healthy individuals (10.50±25.8cm) (p<0.05). No significant differences were observed between the groups regarding CAM. Conclusion: Mucus from healthy individuals allows better mucociliary transport compared to that from patients with lung diseases. However, the mucus from COPD patients allows a better transport by coughing, demonstrating that these individuals have adapted to a defence mechanism compared to patients with bronchiectasis, who have impairment in their ciliary and cough transport mechanisms. © 2012 Sociedade Portuguesa de Pneumologia.

Inflammatory cysts, granulomas, abscesses, and fibrous scars represent most periapical radiolucencies. However, other less common lesions, such as orthokeratinized odontogenic cysts (OOCs), can be found at this region, and they deserve to be discussed because the prognosis for an OOC is different from that expected for the ordinary inflammatory periapical diseases.An interesting case of OOC associated with a nonvital tooth in a 40-year-old woman is described. After a previous clinical diagnosis of a radicular cyst, the tooth was extracted, and the lesion was enucleated and submitted to microscopy examination.Because of the detection of an orthokeratinized epithelium lining, a diagnosis of OOC was concluded. After 2 years of periodic follow-up, no signs of recurrence were detected.The presence of keratin in radicular lesions must be carefully evaluated to eliminate the diagnosis of lesions with more aggressive behavior, such as an OOC or even a keratocystic odontogenic tumor. Hence, histopathologic examination is mandatory to confirm the type of lesion and to differentiate other pathologic conditions, therefore establishing patients prognoses precisely.
