Objective To verify the association of changes on physical activity levels during coronavirus disease 2019 (COVID-19) outbreak of individuals with normal weight and overweight/obesity, and the influence of sex in this relationship. Methods This cross-sectional study (survey research) was conducted in Brazil between May 5 and May 17, 2020. Participants (n=1,828 / 1,062 women >18 years) were invited through social media to answer a structured questionnaire via Google Forms. The online assessment included self-reported responses to questions on physical

Background. STRs are powerful tools intensively used in forensic and kinship studies.Aim. In order to assess the effectiveness of non-CODIS genetic markers in forensic and paternity tests we studied the genetic composition of six mini short tandem repeats -mini-STRs- (D1S1656, D2S441, D6S1043, D10S1248, D12S391, D22S1045) and the microsatellite SE33 in Mestizo and Amerindian populations from Mexico.Subjects and methods. Using multiplex polymerase chain reactions and capillary electrophoresis we genotyped all loci from 870 chromosomes and evaluated the statistical genetic parameters.Results. All mini-STRs studied were in agreement with HW and linkage equilibrium, however, an important HW departure for SE33 was found in the Mestizo population (P ≤ 0.0001). Regarding paternity and forensic statistical parameters, high values of combined power discrimination and mean power of exclusion were found using these seven markers. The principal coordinate analysis based on allele frequencies of three mini-STR...
