Growth Performance, Carcass and Meat Traits of Autochthonous Arouquesa Weaners Raised on Traditional and Improved Feeding Systems.

Arouquesa is an autochthonous bovine breed known for its Arouquesa PDO beef labeling. There are several production systems under the definition of PDO labeling. This study aimed to compare the effect of different production systems on carcass and meat traits for the Arouquesa breed. Two trials differing in diet and weaning age were conducted. The first trial included a TF group fed the traditional way and weaned at 9 months; a TF + S1 group, equal to TF, but with a starter supplement; and finally, a S1 + S2 group that was fed with a starter and a growth supplement and weaned at 5 months. The second trial was composed of a TF + S3 group fed like the TF + S1 group but reared until 12 months with a finishing supplement, and finally, the S3 group fed like the S1 + S2 group but reared until 12 months. In the first trial, the TF + S1 and S1 + S2 groups showed higher final live weight and average daily gain. In the second trial, we observed differences in the subcutaneous fat that was higher in the S3 group. Regarding meat traits, we observed differences in exudative and cooking losses in the first trial. In general, supplementation improved meat production without affecting meat quality parameters.

Factors associated with suicide ideation of healthcare university students / Factores relacionados a la ideación suicida de universitarios de la área de salud / Fatores associados à ideação suicida de universitários da área da saúde

ABSTRACT Objectives: to analyze the factors associated with suicidal ideation in students from healthcare graduation courses. Methods: quantitative, cross-sectional study, with 251 students from the courses of radiology, speech-language therapy, medicine, nutrition, health service management, and nursing, from a federal higher education institution in the Southeast of Brazil. Data were collected from August to October 2019, using an electronic questionnaire. Results: the prevalence of suicidal ideation among participants was 26.33%. In the final logistic regression model, only depressive symptoms were associated with suicidal ideation. Having symptoms of depression increased the chances of suicidal ideation 2.6 times. Conclusion: the high prevalence of suicidal ideation and its associated factors constitutes a situational diagnosis that demands the elaboration of public and institutional policies, focused on the promotion and attention to the mental health of the students.

RESUMEN Objetivos: Analizar los factores relacionados a la ideación suicida de estudiantes de cursos de grado de la área de salud. Métodos: Estudio cuantitativo, transversal, con 251 alumnos de los cursos de Radiología, Fonoaudiología, Medicina, Nutrición, Gestión en Servicios de Salud y Enfermería de una institución federal de Educación Superior en el Sudeste brasileño. Los datos fueron recolectados en el período de agosto a octubre de 2019, por medio de encuesta electrónica. Resultados: La prevalencia de ideación suicida entre los participantes fue de 26,33%. En el modelo de regresión logística final, sólo síntomas depresivos fueron relacionados a la ideación suicida. Tener síntomas depresivos aumentó en 2,6 las chances de presentar ideación suicida. Conclusión: La alta prevalencia de la ideación suicida y sus factores relacionados constituyen un diagnóstico situacional que demanda la elaboración de políticas públicas e institucionales, enfocando la promoción y la atención a la salud mental de los estudiantes.

Evaluation of polymorphisms in repair and detoxification genes in alcohol drinkers and non-drinkers using capillary electrophoresis.

Alcohol use disorder (AUD) causes about 3.3 million deaths around the world each year. It is the primary risk factor for the global burden of diseases in American countries. Long-term abuse of alcohol induces numerous molecular and biochemical changes in tissues exposed to alcohol. The toxic effects of alcohol are mediated by DNA damage through various mechanisms, such as induction of oxidative damage, DNA adducts, crosslinks, and DNA strand breaks. The main aim of the current study was to compare the frequency of SNP polymorphisms in XRCC1 (rs7997782) and GSTP1 (rs1695) genes involved in DNA repair of single strand breaks (SSB) and xenobiotic detoxification between alcohol addicts and a control group comprised of non-drinkers. Genetic polymorphisms were identified following allelic specific PCR designed to generate the amplicons containing the variants. Then amplicons were sequenced, and sequences were aligned against the human genome reference deposited in GenBank using the CLC Sequence Viewer software (version 7.6.1). The GG homozygotes in rs1695 (GSTP1) were significantly (p = 0.023) 3.8x more frequent among those with AUD when compared to the control group. No SNP variation was observed in rs7997782 (XRCC1). rs1695 variant has been associated with susceptibility to various diseases, including those related to alcohol consumption.

Floristic composition and dispersal syndromes at an urban remnant from the Atlantic forest in Brazilian Northeast - doi: 10.4025/actascibiolsci.v33i4.7142 / Floristic composition and dispersal syndromes at an urban remnant from the Atlantic forest in Brazilian Northeast - doi: 10.4025/actascibiolsci.v33i4.7142

Floristic composition and dispersal syndromes were determined along one year in an open ombrophilous forest fragment in the Municipal Park of Maceió, Alagoas State, Brazil. A total of 178 species belonging to 61 families were examined. Fabaceae was the most species-rich family, with 24 species. Among sampled species, 123 had their syndromes of diaspore dispersal determined, and most of them (69%) were zoochoric. Anemochoric and autochoric plants represent 11 and 20% from the total, respectively. The data about reproductive phases indicate coincident peaks of flowering and fruiting in August, at the end of the rainy season. The results are in accordance to those expected for ombrophilous forest with poorly defined seasonality.
