title: A Microrheological Study of Poly(Methyl Methacrylate) Elastomer/Poly(Ethylene Terephthalate) (PMMAelast/PET) Blends

description: This study involved an evaluation of the influence of phase inversion in poly(methyl methacrylate) elastomer/poly(ethylene terephthalate) binary blends (PMMAelast/PET) and the effect of the addition of poly(methyl methacrylate-glycidyl methacrylate-ethyl acrylate) (MGE) interfacial compatibilizer on the microrheological properties of this polymer blend. Thermal, dynamic mechanical thermal, rheological and morphological analyses were performed using sensitive techniques such as differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA), parallel plates rheometry in the linear viscoelastic region, and atomic force microscopy (AFM), respectively. In this study, it was found that variations in the percentage of the PET phase influenced the correlation between the rheological properties at low shear rates and the morphology of the PMMAelast/PET binary blend and of the PMMAelast/PET/MGE compatibilized blend.

title: Cell block specimens applied to diagnostic routine of thyroid fine-needle aspiration biopsy

description: ABSTRACT Introduction: Various preparations can be used in diagnostic cytology, including conventional smears (CS), liquid-based preparations (LBP) and cell block (CB). Objective: The aim of this study is to evaluate the quality of CB preparations in addition to conventional cytological specimens in cases of fine-needle aspiration biopsy (FNAB) of thyroid nodules in diagnostic routine. Method: One hundred and six consecutive cases of FNAB routine thyroid nodules were independently evaluated by two cytopathologists (Obs1 and Obs2) on the cellularity of SM, LBP and CB. Results: The cellularity was rich/moderate in 56 (52.8%) CBs for both observers. LBP showed rich/moderate cellularity in 86 (81.1%) cases for Obs1 and 91 (85.8%) for Obs2; among these cases, CB showed the same cellularity in 52/86 (60.4%) cases for Obs1 and 54/91 (59.3%) for Obs2. SM showed rich/moderate cellularity in 86 (81.1%) cases for Obs1 and 87 (82%) for Obs2; among these cases, CB showed the same cellularity in 48/86 (55.8%) cases for Obs1 and 54/87 (62%) for Obs2. CB cellularity was higher than that in LBP in only five cases for Obs1 and three for Obs2. LBP was assessed as low/absent in only five (4.7%) and six (5.6%) cases for Obs1 and Obs2, respectively. Conclusion: CB can be routinely used as additional specimen in material obtained from thyroid nodules FNAB, without adversely affecting LBP specimens, enabling the conduction of further immunohistochemical and molecular studies.

title: Effects of Aging at 450°C on the Pitting Corrosion Resistance and Toughness of AISI 317L Steel Welded by GTAW and FSW

description: Austenitic stainless steels are high corrosion resistant alloys widely used in many industrial fields. Among this family of steels, AISI 317L stands out due to its higher localized corrosion resistance when compared to the traditional grades AISI 304L and AISI 316L. In some applications in oil refineries, the AISI 317L is being specified for services at moderately high temperatures. At the same time as it is sought to use new stainless steels, is also desirable to apply and develop emerging welding processes, replacing conventional ones, in order to achieve better behavior in service. In this respect, this work studied the effects of thermal aging on the toughness and resistance to pitting corrosion of AISI 317L steel weld metals produced by the Gas Tungsten Arc Welding (GTAW) and Friction Stir Welding (FSW) joining processes. After prolonged exposures at 450°C, for 200h, 300h and 400h, the microstructural characterization by scanning electron microscopy (SEM), toughness evaluation and anodic polarization tests in 3.5% NaCl solution were performed. The results showed that the increase of the exposure time in both weld metals caused a toughness decrease. The pitting potentials measured in the polarization tests also decreased with the aging at 450ºC.

title: Repetitive DNAs and shrink genomes: A chromosomal analysis in nine Columbidae species (Aves, Columbiformes)

description: Abstract An extensive karyotype variation is found among species belonging to the Columbidae family of birds (Columbiformes), both in diploid number and chromosomal morphology. Although clusters of repetitive DNA sequences play an important role in chromosomal instability, and therefore in chromosomal rearrangements, little is known about their distribution and amount in avian genomes. The aim of this study was to analyze the distribution of 11 distinct microsatellite sequences, as well as clusters of 18S rDNA, in nine different Columbidae species, correlating their distribution with the occurrence of chromosomal rearrangements. We found 2n values ranging from 76 to 86 and nine out of 11 microsatellite sequences showed distinct hybridization signals among the analyzed species. The accumulation of microsatellite repeats was found preferentially in the centromeric region of macro and microchromosomes, and in the W chromosome. Additionally, pair 2 showed the accumulation of several microsatellites in different combinations and locations in the distinct species, suggesting the occurrence of intrachromosomal rearrangements, as well as a possible fission of this pair in Geotrygon species. Therefore, although birds have a smaller amount of repetitive sequences when compared to other Tetrapoda, these seem to play an important role in the karyotype evolution of these species.

title: Cross-cultural adaptation and validation of the Brazilian version of the Beliefs about Emotions Scale

description: Abstract Introduction Beliefs about the unacceptability of expression and experience of emotion are present in the general population but seem to be more prevalent in patients with a number of health conditions. Such beliefs, which may be viewed as a form of perfectionism about emotions, may have a deleterious effect on symptomatology as well as on treatment adherence and outcome. Nevertheless, few questionnaires have been developed to measure such beliefs about emotions, and no instrument has been validated in a developing country. The current study adapted and validated the Beliefs about Emotions Scale in a Brazilian sample. Methods The adaptation procedure included translation, back-translation and analysis of the content, with the final Brazilian Portuguese version of the scale being tested online in a sample of 645 participants. Internal consistency of the scale was very high and results of a principal axis factoring analysis indicated a two-factor solution. Results Respondents with high fatigue levels showed more perfectionist beliefs, and the scale correlated positively with questionnaires measuring anxiety, depression and fear of negative evaluation, confirming cross-cultural associations reported before. Finally, men, non-Caucasians and participants with lower educational achievement gave greater endorsement to such beliefs than women, Caucasian individuals and participants with higher educational level. Conclusions The study confirms previous clinical findings reported in the literature, but indicates novel associations with demographic variables. The latter may reflect cultural differences related to beliefs about emotions in Brazil.

title: Incidence of aflatoxin M1 contamination in milk, white cheese, kashar and butter from Sakarya, Turkey

description: Abstract The purpose of this research is to determine the incidence and occurrence of aflatoxin M1 (AFM1) in 104 samples of milk, white cheese, kashar and butter in Sakarya, Turkey. Followed by immunoaffinity column (IAC) purification, high performance liquid chromatography (HPLC)-fluorescence detection method was implemented to analyze the samples. Results show that 61.5% of milk, 40% of white cheese, 65.4% of kashar and 29.6% of butter contains AFM1. In 53 of samples (50.96%) are not determined AFM1. The amount of AFM1 in 51 samples (49.04%) ranges from 2.4 to 47.8 ng/L/kg. AFM1 levels do not exceed the limit set by Turkish regulations (50 ng/L/kg). However, the incidence of AFM1 contamination is a potential health risk for customers, particularly for children and infants. These results emphasize the significance of constant monitoring of AFM1 levels in milk and dairy products (MDPs) in Sakarya, Turkey.

title: Evaluation of Biopolimeric Films of Cassava Starch with Incorporation of Clay Modified by Ionic Exchange and its Application as a Coating in a Fruit

description: Coatings technologies with biopolymeric films are effective in maintaining the chemical and sensory characteristics of several fruits. Cassava starch is an attractive biopolymeric because of its renewable characteristics and low cost, but it has a high transfer rate of water vapor. Hydrophilic compounds of organically modified montmorillonite clay by ion exchange can be used to improve the limiting properties of starch in exchange for additives such as lipids. The solutions prepared with 5% m/v starch / 5% m/m cationic / anionic clay and uncoated were applied in caja fruit, harvested at physiological maturity, selected for absence of defects and color uniformity. The experimental design was performed with four storage times (0, 3, 6 and 9 days). For the maturation index, there was an isolated effect of the type of coating and storage time, showing the composite films of modified cationic clay with greater MI of the fruits in comparison to the control fruits.

title: A LOOK AT WOMEN'S TRANSITION FROM FORMAL LABOR TO SELF-EMPLOYMENT BASED ON ENDOGENOUS STIMULI

description: ABSTRACT Purpose: The objective of this study is to analyze the stimuli that lead women to leave formal jobs and seek self-employment. Originality/value: Changes in the social patterns and lifestyle of the population have made research aimed at career and gender gain relevance. There is, however, a lack of research on women who have left their organizations and the main stimuli of this movement, exogenously and endogenously driven, which are relevant as result of social and cultural factors intrinsic to the family environment that leads to a career change. Design/methodology/approach: The qualitative methodology of narrative analysis was used, adequate to the examination of the phenomenon in question. Findings: The following stimuli were highlighted: self-fulfillment and search for flexibility; professional achievement; personal challenges; high level of career ambition; and search for a feminine identity. The results diverged in relation to the existing literature, mainly focused on exogenous factors. Although mentioning difficulties in reconciling work with domestic activities, the professionals under study, previously occupying formal positions in companies, did not perceive or did not undergo any type of limitation at work, such as the phenomenon of glass ceiling, difficulties in working on the masculinized leadership model, family pressures, and fear of misuse of sexuality. Entrepreneurship emerged mainly as a career option as a form of personal self-actualization and not through imposition arising from social, family or labor difficulties.

title: The association between adult-type hypolactasia and symptoms of functional dyspepsia

description: Abstract Functional dyspepsia and lactose intolerance (adult-type hypolactasia, ATH) are common conditions that may coexist or even be confounded. Their clinical presentation can be similar, however, lactose intolerance does not form part of the diagnostic investigation of functional dyspepsia. Studies on the association between functional dyspepsia and ATH are scarce. This study aimed to evaluate whether ATH is associated with symptoms of functional dyspepsia. Patients fulfilling the Rome III diagnostic criteria for functional dyspepsia underwent genetic testing for ATH. Dyspeptic symptoms were evaluated and scored according to a validated questionnaire. The diagnostic criteria for ATH was a CC genotype for the -13910C/T polymorphism, located upstream of the lactase gene. The mean scores for dyspeptic symptoms were compared between patients with ATH and those with lactase persistence. A total of 197 functional dyspeptic patients were included in the study. Mean age was 47.7 years and 82.7% patients were women. Eighty-eight patients (44.7%) had a diagnosis of ATH. Abdominal bloating scores were higher in ATH patients compared to the lactase persistent patients (P=0.014). The remaining dyspeptic symptom scores were not significantly different between the two groups. The study results demonstrate an association between ATH and bloating in patients with functional dyspepsia.
