Litogeoquímica E aspectos Petrogenéticos dos basaltos da Província Magmática do Paraná na porção centro-norte do Estado de São Paulo

The petrographic and geochemical characterization of flood basalts of Serra Geral Formation are here presented. The investigated areas are situated in four different regions of São Paulo state: Jaú, Ribeirão Preto, Franca and Fernandópolis. They represent almost the total area of outcrops of basalts in the São Paulo State. The petrographical data reveals that these rocks are constituted mainly by plagioclase (30-40%), pyroxenes, augite and pigeonita (20-30%) and magnetite (5-15%), and show a intergranular texture and its varieties intersertal, hialophitic and pilotaxitic. The geochemical data show a basic and tholeiitic affinity of the studied basalts, with high-Ti content (TiO2 > 1.8%), typical of the northern region of Paraná Basin. Three different magma-types were recognized: Paranapanema, Urubici and Pitanga. The first magma-type is concentrated in the Fernandópolis region, the second in the Franca region, and the Pitanga occurs in the Ribeirão Preto and Jaú regions. The distribution patterns of these magma-types and the detailed study of geochemical data showed that they are, probably, generated by a melting of a continental lithospheric mantle.

Spermatogenesis and karyotypes of three species of water striders (Gerridae, Heteroptera).

Although they are of economic importance, there have been few cytogenetic studies of the Gerridae (Heteroptera) in Brazil. We examined spermatogenesis (meiosis and spermiogenesis) and nucleolar behavior in three species of the family Gerridae. Brachymetra albinerva and Halobatopsis platensis were found to have a chromosome complement of 2n = 25 (24A + X0) and Cylindrostethus palmaris 2n = 29 (28A + X0) chromosomes. Fifteen individuals of these species were collected from the reservoir of São José do Rio Preto, SP, using screens and were transported in pots containing water to the laboratory, where cytogenetic preparations were made. The polyploidy nuclei are formed by several heteropyknotic regions; cells in meiotic prophase have a heteropyknotic region that is probably the sex chromosome, and the chromosomes from chiasmata. The spermatids are rounded and have a heteropyknotic region at the periphery of the nucleus; the sperm head is small, with a long tail. Silver impregnation of meiotic cells showed one or more disorganized bodies around the perichromosomal sheath. The round spermatids had two bodies next to each other, but these were elongated; one of the bodies remained in the head and the other migrated to the initial part of the tail at the end of spermagenesis, when the staining was no longer evident. The meiotic cells appear during spermatogenesis and have very similar silver-impregnation patterns in different species of Heteroptera.

Health status profile of climacteric women

Study design: Retrospective analysis of medical records. Purpose: This study aimed to determine the prevalence of obesity, diabetes mellitus, hypertension and dyslipidemia in a group of climacteric women. Methods: Study of the first patients treated at the Menopause Clinic (ACLI), Department of Obstetrics and Gynecology, School of Medicine of Ribeirão Preto (USP), from 1983 to 2007. Data on weight, height, BMI, biological group, diagnosis of hypertension, diabetes and dyslipidemia was collected from February/2008 until April/2008. Results: From 1983 until 2007, 400 patients were followed up, and 272 had their records registered. Of these 272 patients, 628 were selected queries, and therefore, on average, each woman had three returns. Women over the age of 29 and maximum of 80 years and median BMI above 25kg/m2. The prevalence of diabetes, hypertension and dyslipidemia was respectively 32%, 68% and 54%. The prevalence of NCDs and BMI was higher for the later groups. Conclusion: Climacteric women treated at a hospital level care center showed a worsening of the BMI and the prevalence of noncommunicable chronic diseases over time, which is urging a closer look at health professionals in this population group.

European Ancestry Predominates in Neuromyelitis Optica and Multiple Sclerosis Patients from Brazil

Background: Neuromyelitis optica (NMO) is considered relatively more common in non-Whites, whereas multiple sclerosis (MS) presents a high prevalence rate, particularly in Whites from Western countries populations. However, no study has used ancestry informative markers (AIMs) to estimate the genetic ancestry contribution to NMO patients. Methods: Twelve AIMs were selected based on the large allele frequency differences among European, African, and Amerindian populations, in order to investigate the genetic contribution of each ancestral group in 236 patients with MS and NMO, diagnosed using the McDonald and Wingerchuck criteria, respectively. All 128 MS patients were recruited at the Faculty of Medicine of Ribeirão Preto (MS-RP), Southeastern Brazil, as well as 108 healthy bone marrow donors considered as healthy controls. A total of 108 NMO patients were recruited from five Neurology centers from different Brazilian regions, including Ribeirão Preto (NMO-RP). Principal Findings: European ancestry contribution was higher in MS-RP than in NMO-RP (78.5% vs. 68.7%) patients. In contrast, African ancestry estimates were higher in NMO-RP than in MS-RP (20.5% vs. 12.5%) patients. Moreover, principal component analyses showed that groups of NMO patients from different Brazilian regions were clustered close to the European ancestral population. Conclusions: Our findings demonstrate that European genetic contribution predominates in NMO and MS patients from Brazil. © 2013 Brum et al.

Frequency of reported European ancestry among multiple sclerosis patients from four cities in the southern and southeastern regions of Brazil

Recent reports on the prevalence of multiple sclerosis (MS) have described discrepancies between the rates in cities in the northeastern and southeastern regions of Brazil, representing a north-south gradient. European immigrants settled in southeastern and southern Brazil at the beginning of the twentieth century. In this study, we report the frequency of European ancestors among Brazilian MS patients in four cities in the southern and southeastern regions of Brazil. Methods: A total of 652 consecutive patients with confirmed MS diagnoses seen at four centers in Belo Horizonte, Ribeirão Preto, Londrina and Santos were asked about the origin of their ancestors, going back three generations. Results: 287 (44%) reported Italian ancestry, 211 (32%) reported that all ancestors were born in Brazil, 49 (7.5%) had Portuguese ancestry and 70 (10%) had Spanish ancestry. The patients in Belo Horizonte and Londrina reported higher proportions of Italian ancestry than the proportions estimated for the populations of their respective States. Conclusion: Brazil has a north-south gradient of 0.91/100,000 per degree of latitude, which is higher than the gradient for Latin America. Since the largest immigrant group that settled in southern and southeastern Brazil was from Italy, it is possible that Italian immigration was one of the factors that have contributed toward increasing the prevalence of MS in these regions. © 2013 Elsevier B.V.

Tropical influence in oriental gardens in Brazil

In the contemporary landscaping, among the gardening styles, the Japanese Garden plays very important rule and influence. The Japanese Garden has originated in China-the cradle of gardening culture; and Korea. Their vegetable elements, architectural features and fauna are characteristic, due to use of stones, water, bridges, stoned lamp, bonsai, carps and bamboo (Prunus serrulata, Camellia japonica, Ophiopogon japonicas) and many others. In Brazil, the Japanese Garden has massive influence, the presence of native elements typically tropical is very noticeable. This influence can be observed both in architecture, vegetation and fauna. Thus, this study aimed to identify and analyze the tropical elements in Japanese Gardens in cities such as São Paulo. Japanese Gardens in Brazil were chosen from the following cities: Sao Paulo State, Garça, Jaboticabal and Ribeirão Preto. It was observed, mostly in the presence of different palms species, plants of the Zingiberales order, Alpinia purpurata and styled architectural elements such as lakes. Some elements were able to apply the philosophy of the Japanese Garden, other not.
