title: Abundance and size structure of planktonic protist communities in a Neotropical floodplain: effects of top-down and bottom-up controls

description: Abstract: Aim: We aimed to assess the influence of bottom-up and top-down control mechanisms on the abundance and size structure of protist communities (heterotrophic flagellates and ciliates). We formulated the following hypothesis: bottom-up control mechanisms, related to the availability of resources in the environment, are responsible for structuring the abundance of these communities, whereas top-down control mechanisms, related to predation effects, determine the size pattern of these organisms. Methods Samples for planktonic organisms were taken in 20 shallow lakes belonging to the upper Paraná River floodplain. We evaluated linear regression models to select the best model which predicts the patterns observed according to Akaike Information Criterion. Results The best models selected to explain the abundance of heterotrophic flagellates included negative relations with picophytoplankton abundance and positive with rotifers abundance, while for their size structure, negative relationships were found with heterotrophic bacteria, ciliates and rotifers biovolumes. In relation to the ciliates, their abundances were positively related to the rotifers and picophytoplankton abundances and negatively with the heterotrophic bacteria abundance. On the other hand, for the size structure, the best models selected strong negative relations with the microcrustaceans biovolumes, in addition to relations with the different fractions of the phytoplankton. Conclusion For both flagellates and ciliates, their abundance is being mainly regulated by a bottom up control mechanism, whereas for the size structure the results showed that both food resources and predators were important, indicating that bottom-up and top-down mechanisms act simultaneously in determining the size of these microorganisms.

title: Histopatology of the reproductive tract of Nellore pubertal heifers with genital ureaplasmosis

description: ABSTRACT In order to study and characterize the lesions in the reproductive tract of Nellore heifers naturally infected with Ureaplasma diversum and presenting granular vulvovaginitis syndrome (GVS), fragments of uterine tube, uterus, cervix, vagina and vulva of 20 animals were evaluated. The macroscopic lesions of the vulvovaginal mucosa were classified in scores of “1” mild, until “4”, severe inflammation and pustular or necrotic lesions. The histopathological evaluation was performed using scores of “1” to “4”, according to the inflammatory alterations. The fragments with severe microscopic lesions (3 and 4) were from the uterine tubes and uterus, which showed leukocytes infiltration and destruction and/or necrosis of epithelium. Alterations in the lower reproductive tract fragments were mild, but characteristics of acute inflammatory processes. The histopathological findings of the reproductive tract of females naturally infected with Ureaplasma diversum are consistent with injuries that compromise the environment from the local where spermatozoa acquires ability to fertilize an oocyte until those where the oocyte is fertilized. Therefore, animals with GVS should be identified early in the herd, because, besides the reduction in the fertility rates caused by tissue damages, they can contribute to disseminate the microorganism. Key words: bovine, tissue evaluation, reproduction, Ureaplasma diversum.

title: Detection of SNPs in the BMP6 Gene and Their Association with Carcass and Bone Traits in Chicken

description: ABSTRACT BMP6, a member of the subfamilies of the morphogenetic proteins (BMPs), plays a crucial role in osteogenic and chondrocyte differentiation in vitro and stimulates chondrogenesis, making chondrocytes differen-tiate on their terminal stage. The objective of this study is to explore the relationship between polymorphism of BMP6 gene and slaughter traits in chicken respectively. We screened the exonic and intronic regions of BMP6 gene by DNA pool construction and amplified DNA fragment by PCR, and finally, we got nine SNPs. Association analysis revealed that BMP6 had no significant association among all slaughter traits in Yellow bantam chicken. However, BMP6 had a significant difference with femur weight, tibia weight, femur length (p&lt;0.05), and was extremely significant with tibia length (p&lt;0.01) in Avian chicken. Moreover, femur perimeter also had significant correlation with BMP6 in Avian chicken. These results provide useful information for further investigation on the function of chicken BMP6 gene.

title: Cross-sectional study on the association between frailty and violence against community-dwelling elderly people in Brazil

description: ABSTRACT BACKGROUND: The physical, emotional and cognitive limitations that may be present in the aging process, coupled with family unpreparedness, may lead to greater dependence among the elderly. This favors development of frailty syndrome and greater levels of violence against the elderly. The objective here was to analyze the association between violence against the elderly and frailty; and the geographic distribution of violence against the elderly according to the presence of frailty syndrome. DESIGN AND SETTING: Cross-sectional study on 705 community-dwelling elderly people in Uberaba (MG), Brazil. METHODS: The Fried frailty phenotype and conflict tactics scale were used. Data were analyzed using descriptive statistics, the chi-square test and a logistic regression model. The intensity of the events and the relationship between clusters of violence and frailty status were assessed by means of kernel estimation. RESULTS: The adjusted analysis indicated that pre-frailty and frailty were associated with physical and verbal aggression (odds ratio, OR = 1.51; 95% confidence interval, CI: 1.04-2.19; OR = 2.12; 95% CI: 1.29-3.47), frailty was associated with physical aggression (OR = 2.48; 95% CI: 1.25-4.94) and pre-frailty and frailty were associated with verbal aggression (OR = 1.48; 95% CI: 1.03-2.15; OR = 2.15; 95% CI: 1.31-3.52), respectively. Regardless of frailty status and its relationship with violence, clusters of occurrences were larger in similar regions in the southeastern part of the municipality; but superimposition of overlays relating to aggression showed that for frail individuals the clusters were smaller than for non-frail and pre-frail individuals. CONCLUSIONS: The condition of frailty was associated with greater chances of violence against the elderly.

title: The Persuasive Power of Refutation in Collective Argumentation

description: Abstract This study is framed in mathematical classroom argumentation. Its purpose was to identify functions of refutation of claims in collective argumentation. This was done through the implementation of a theoretical methodological approach based on the argumentative model of Toulmin (2003), which allowed the study of the collective argumentation and their structures within the classroom. Along with the theory convictions, we found how refutation has a persuasive power on the student's arguments, with this being another function of refutation.

title: Acute stress disorder and defense mechanisms: a study of physical trauma patients admitted to an emergency hospital

description: Abstract Introduction: Acute stress disorder (ASD) encompasses a set of symptoms that can arise in individuals after exposure to a traumatic event. This study assessed the defense mechanisms used by victims of physical trauma who developed ASD. Method: This was a controlled cross-sectional study of 146 patients who suffered physical trauma and required hospitalization. A structured questionnaire was used to evaluate ASD symptoms based on DSM-5 diagnostic criteria, in addition to the Defense Style Questionnaire (DSQ). Results: Ten participants (6.85%) received a positive diagnosis of ASD, and 136, (93.15%) a negative diagnosis. The majority of the sample consisted of men with median age ranging from 33.50 to 35.50. The most prevalent defense mechanisms among the 10 patients with ASD were cancellation and devaluation, which belong to the neurotic and immature factors, respectively. Positive associations between the presence of symptoms from criterion B of the DSM-5 and defense mechanisms from the DSQ were found. These included the mechanisms of undoing, projection, passive aggression, acting out, autistic fantasy, displacement, and somatization. Conclusion: Patients with ASD employed different defense mechanisms such as undoing and devaluation when compared to patients not diagnosed with ASD. These results mark the importance of early detection of ASD symptoms at a preventative level, thereby creating new possibilities for avoiding exacerbations related to the trauma, which represents an important advance in terms of public health.

title: Hepatitis C: evaluation of outcomes and georeferencing of cases in Santa Cruz do Sul, Brazil, between 2002 and 2015. A cross-sectional study

description: ABSTRACT BACKGROUND: Hepatitis C virus infection is one of the main causes of chronic liver disease, with high death rates. The aim here was to analyze case outcomes, sociodemographic and clinical characteristics and spatial distribution among patients diagnosed with hepatitis C in the city of Santa Cruz do Sul (RS), Brazil. DESIGN AND SETTING: Cross-sectional study on 200 cases of hepatitis C in Santa Cruz do Sul that were notified between 2002 and 2015. METHODS: Secondary data including sociodemographic and clinical variables and type of outcome (death, follow-up, abandonment or clinical cure) were gathered. The spatial distribution analysis on hepatitis C virus cases according to outcome was based on information regarding residential address. RESULTS: 58.5% of the patients were 41 years of age and over, 67% were males and 92.5% had the chronic form of the disease. The most frequent transmission route was illicit drug injection (29%); 15.1% of the patients presented coinfection with the human immunodeficiency virus (HIV). Regarding outcomes, 31% achieved clinical cure, 10% died and 20% abandoned follow-up. The cases studied were mainly located in regions of the city characterized by lower socioeconomic status, with high frequency of places used for drug trafficking. CONCLUSION: The population consisted of adults aged 41 years and over, mostly with chronic hepatitis C. The most common transmission routes were illicit drug injection and blood transfusions. There were high rates of HIV coinfection and abandonment of disease monitoring and predominance of cases in neighborhoods with low socioeconomic status.

title: Subject, object, grandpa, enemy: a comparative ethnomuseology among the Mebêngôkre-Kayapó and Baniwa of Brazil

description: Abstract Ethnomuseology seeks to put indigenous people in dialog with their own material culture heritage. This article reflects on collaborative research carried out with Mebêngôkre-Kayapó and Baniwa consultants on important collections of both groups from the early twentieth century. In addition to noting differences between museological or scientific and indigenous concepts about museum objects, we also noticed a number of cultural differences in the way the two indigenous groups related to objects from their past. While both cultural groups attributed subjective characteristics to museum objects, for the Mebêngôkre-Kayapó this subjectivity expressed itself mostly in terms of possible threats to visitors of the museum collections, leading to a hesitancy to handle museum objects, assumed to be war trophies captured in the past from dangerous enemies. The Baniwa, by contrast, expressed great affection for ‘grandpa’s things’, and they felt they had a right to handle objects that represent the heritage of patrilineal clans. This experience in ethnomuseology highlights the diversity of indigenous concepts, attitudes and expectations about museum collections and the need for the dialogical approach to collaborative research.

title: Anthropometric indicators as predictors in determining frailty in elderly people

description: Abstract The scope of this article is to analyze anthropometric indicators as predictors in determining frailty in elderly people. This is a cross-sectional, family-based and analytical study. The survey was composed of 316 elderly subjects. The association between the anthropometric markers and frailty was tested using the Logistic Regression technique. However, the power of frailty diagnosis using anthropometric markers and the identification of the best cutoff points were evaluated using the parameters provided by the Receiver Operating Characteristic (ROC) curve. The anthropometric indicators of nutritional status: calf circumference, body mass index and corrected arm-muscle area are inversely associated with frailty. Thus, an increase in the values of these indicators is a protective factor against this syndrome. Analyzing body mass index and calf circumference simultaneously in order to perform a simpler screening for frail elderly people is recommended, as these indicators show good sensitivity and are easier to measure.
