title: Sex dimorphism and ontogenetic allometry of Goyazana castelnaui (Crustacea, Brachyura)

description: ABSTRACT: In crustaceans, studies of dimorphism using geometric morphometry approach are particularly appropriate due to the facility and accuracy in the identification of homologous landmarks. The aim of this study was identify the existence of sexual and age dimorphism of freshwater crab Goyazana castelnaui (H. Milne-Edwards, 1853), except for the dimorphism of the pleon, since it is an aspect intrinsic to the Brachyura. Were determined 10 anatomical landmarks for ventral view and 11 for the dorsal view. A covariance matrix was generated, containing factors related to the sexes and age groups of each sex, and the images were considered symmetrical. The canonical variate analysis (CVA) and discriminant analysis (DA) were performed with 999 permutations and as comparisons were made based on the Hotteling test (T²) of the Procrustes distance. In the ventral view no variation was found in the form of juveniles and adults of females and males (p = 0.4548, p = 0.131, respectively) based on the Procrustres distance. In the dorsal view, a separation was observed between the adult females and the other groups, indicating a noticeable modification of the cephalothorax volume for the allocation of the gonads.

title: Management of Atypical Squamous Cell Cases: A Prospective Study of Women seen at a Private Health Service in Northeastern Brazil

description: Abstract Objective To assess the management chosen by gynecologists after atypical squamous cells (ASCs) cytology results, and to evaluate the outcomes of these cases in Brazilian women. Methods A prospective observational study evaluated the initial management offered by the gynecologist in the case of 2,458 ASCs cytology results collected between January of 2010 and July of 2016. The outcomes of the cytology, high-risk human papilloma virus (HR-HPV) test and histology were compared in two subgroups: atypical squamous cells of undetermined significance (ASC-US) and atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (ASC-H). Results In many cases of ASC-US (36.97%) and ASC-H (40.50%), no clinical actions were taken. Cytology was the most frequent follow-up chosen, including for cases of ASC-H, which goes against the conduct recommended in the national guideline. In women over 30 years of age, the period of time elapsed between an ASC-US result and a new cytology was in 13.03 months, in disagreement with the national guideline recommendations (p&lt; 0.0001). Negative for intraepithelial lesions or malignancy (NILM) cytologic (p = 0.0026) and histologic (p = 0.0017) results in the follow-up were associated with prior ASC-US, while negative results for ASC-H were cytologically (p&lt; 0.0001) and histologically associated with high-grade squamous intraepithelial lesion (HSIL) (p&lt; 0.0001). Two invasive cervical carcinomas (ICCs) were found in the follow-up for ASC-H, and there was a statistically significant association (p = 0.0341). A positive HR-HPV test was associated with ASC-H (p = 0.0075). Conclusion The data suggest that even for a population of Brazilian women assisted at private clinics, the national guidelines recommendations for ASCs results are not followed.

title: Association between Microvolt T-Wave Alternans and Malignant Ventricular Arrhythmias in Chagas Disease

description: Abstract Background: Sudden cardiac death is the most frequent death mechanism in Chagas disease, responsible for 55% to 65% of the deaths of patients with chronic Chagas cardiomyopathy (CCC). The most often involved electrophysiological mechanisms are ventricular tachycardia and ventricular fibrillation. The implantable cardioverter defibrillator (ICD) has a beneficial role in preventing sudden death due to malignant ventricular arrhythmias, and, thus the correct identification of patients at risk is required. The association of microvolt T-wave alternans (MTWA) with the appearance of ventricular arrhythmias has been assessed in different heart diseases. The role of MTWA is mostly unknown in patients with CCC. Objectives: To evaluate the association between MTWA and the occurrence of malignant ventricular arrhythmias in patients with CCC. Method: This is a case-control study including patients with CCC and ICD, with history of malignant ventricular arrhythmias (case group), and patients with CCC and no history of those arrhythmias (control group). The MTWA test results were classified as negative and non-negative (positive and indeterminate). The significance level adopted was a = 0.05. Results: We recruited 96 patients, 45 cases (46.8%) and 51 controls (53.1%). The MTWA test was non-negative in 36/45 cases (80%) and 15/51 controls (29.4%) [OR = 9.60 (95%CI: 3.41 - 27.93)]. After adjustment for known confounding factors in a logistic regression model, the non-negative result continued to be associated with malignant ventricular arrhythmias [OR = 5.17 (95%CI: 1.05 - 25.51)]. Conclusion: Patients with CCC and history of malignant ventricular arrhythmias more often have a non-negative MTWA test as compared to patients with no history of arrhythmia.

title: Immigrant women: presence and concealment (São Paulo Provinces, 1880-1930)

description: Abstract This paper aims to shed new light on the female presence in the (im)migration process to the provinces of São Paulo state, approaching different aspects of the experiences, routine tasks, work activities and cultural background of immigrant women. To that end, several sources were evaluated and revised, including letters, working logs, statements, memory journals and articles from daily newspapers or labor press. The text seeks to give a context to the role of immigrant women, both in rural areas, focused in coffee agriculture, or in town areas of São Paulo, where they represent a significant presence in several urban occupations, local trade, industrial activities or domestic housework. In addition, the present paper suggests broadening methodological horizons to study dislocations, questioning the typical universal male figure in immigration studies, and highlighting the importance of facing the migration experience from other perspectives, including that of women.

title: Water stress and temperature on germination and vigor of Handroanthus impetiginosus (Mart. ex DC)

description: ABSTRACT Water availability and temperature are among the main abiotic factors that influence seed germination and vigor, since they act directly on biochemical and physiological processes, which result in the production of the primary root. The objective of this study was to verify the effects of stress on germination and vigor of H. impetiginosus (‘ipê-roxo’) seeds under different temperatures and osmotic agents. The experimental design was completely randomized, in a 6 x 2 factorial scheme (osmotic potentials x temperatures) with four replicates of 25 seeds for each osmotic agent. In order to simulate water stress, polyethylene glycol (PEG 6000) and mannitol solutions were used and distilled water was used as control. Osmotic potentials of 0, -0.2, -0.4, -0.6, -0.8 and -1.0 MPa were evaluated at temperatures of 25 and 30 °C, under 8 h photoperiod. The variables analyzed were: germination, germination speed index, shoot length, root length, and total dry matter of seedlings. Simulated water stress affected seed germination and seed vigor of H. impetiginosus at both temperatures and osmotic agents from -0.6 MPa.

title: Ripening characteristics of vapour heat treated ‘Frangi’ papaya (Carica papaya L. cv. Frangi) as affected by maturity stages and ethylene treatment

description: ABSTRACT ‘Frangi’ papaya is a F1 hybrid cultivar produced by Malaysian Agrifood Corporation Bhd in 2006. Since then, ‘Frangi’ papaya is a new hybrid and its physiology may differ from another cultivars. Several importer countries, such as Japan and China, have made the vapour heat treatment (VHT) an export requirement for disinfestation of fruit flies in Malaysia. The exporting country is also required to carry out ripening treatments with ethylene before export. Therefore, the objective of this work was to determine the effects of maturity stages (4, 5 and 6) and ethylene treatments on ripening characteristics of vapour heat treated papaya during storage at 25 °C. Papaya fruits were treated with VHT systems. After VHT, the fruits were exposed with 100 µL.L–1 ethylene gas at 20 °C for 24 h. Non-ethylene treated fruits (control) were kept separately at 20 °C for 24 h. After 24 h, the fruits were removed from the ripening rooms, and stored at 25 °C. The ripening characteristics of fruits that reached maturity stages 4, 5, and 6 were recorded. Results showed that the fruits ripened normally at 25 °C with or without ethylene following VHT with respect to peel and pulp color, edible firmness and soluble solids concentration (SSC). Fruits at maturity stage 5 were considered at the edible stage by taking into account the firmness, SSC, titratable acidity, and ascorbic acid contents. It is recommended that no ethylene treatment is needed to ripen vapour heat treated fruits, since the ethylene treatment did not affect the ripening process of the fruits.

title: Feeding behavior of octopus Octopus vulgaris Type II (Cuvier, 1797) paralarvae fed on Artemia enriched with microalgae and supplemented with DHA

description: ABSTRACT The inexistence of nutritionally adequate diets in paralarval rearing is the main bottleneck for commercial production of the common octopus Octopus cf. vulgaris. We report the feeding behavior of O. vulgaris Type II paralarvae fed on Artemia sp (0.1 individual. mL-1) nauplii enriched with microalgae Isocrysis galbana and Pavlova lutheri microalgae from 0 to 7 Day After Hatching (DAH).; metanauplii enriched with microalgae and DHA SELCO® lipid emulsion from the 8 DAH. The paralarvae showed active swimming and predation by the 14 DAH, feeding in the most superficial portion of the water column. From the 15 DAH, the paralarvae remained near the bottom and there a decrease in the consumption of artemia was observed. The mortality observed from the 18 DAH and mass mortality of paralarvae on 20 DAH can be attributed mainly to the nutritional composition of the diet. Studies analyzing the biochemical composition and ontogeny of the digestive system during the early life stages should shed some light on the running for an appropriate feeding protocol to the paralarval rearing.

title: Piezoelectricity from Elastic and Dielectric Measurements on Unpoled Ferroelectrics

description: A method is described to assess the piezoelectric response of ferroelectric materials from the temperature dependence of the elastic moduli and dielectric constant of unpoled samples. The limits and advantages over the traditional methods on poled samples are discussed. A quantitative check is made by comparing the piezoelectric softening measured below the ferroelectric transition in the Young's modulus of unpoled ceramic BaTiO3, with the appropriate angular average of the single crystal material constants from the literature. The softening effect of porosity has been taken into account by comparing the moduli of samples with different densities.

title: WEIGHT-BEARING COMPUTED TOMOGRAPHY OF THE FOOT AND ANKLE: AN UPDATE AND FUTURE DIRECTIONS

description: ABSTRACT Spatial understanding of osteoarticular deformities of the foot and ankle is vital to correct diagnosis and therapeutic decision making. Poor reproducibility in conventional standing radiography in three orthogonal views has driven the development of weight-bearing computed tomography (WBCT) technology over the last decade. We analyzed the available literature on WBCT imaging in patients with foot and ankle disorders by performing a literature review of relevant clinical studies in multiple databases including PubMed, MedLine, and Scopus from January 1999 to October 2017. WBCT imaging allows correct evaluation of foot and ankle anatomy with the patient in a standing position, providing images with high spatial resolution, short image acquisition time, low dose of radiation, and costs which are similar to other available imaging technologies. This diagnostic tool can be used for decision making in the treatment of deformities of the ankle, hindfoot, midfoot, and forefoot. Level of Evidence III; Systematic review of level III studies.
