Oocyte competence and gene expression in parthenogenetic produced embryos from repeat breeder and normally fertile buffaloes (Bubalus bubalis) raised in sub-humid tropical climate.

The reproductive management of the buffalo species still faces several unresolved problems, which directly affect the productivity of the herd, one of them being the presence of repeat breeder females. Given this scenario, this study aimed to verify the developmental competence of oocytes obtained from repeat breeder females and submitted to parthenogenetic activation. In addition, embryo gene expression was compared to normally fertile females.

Factors affecting the embryo production in buffalo (): A review.

Under natural and well-managed conditions, the buffalo has good reproductive and productive indices. However, embryo production (IVEP) has been used commercially to maximise the number of elite animals. In this species, several factors (donor management, culture medium, semen, conditions, embryo transfer) still affect the IVEP results.

Frequency of leisure-time physical activity and pulse pressure in the Brazilian population: a population-based study.

Objective: The purpose of this study was to investigate the association between the frequency of leisure-time physical activity and brachial pulse pressure (PP), according to physical activity intensity and type, sex, and age, in the general Brazilian population.

Study Design: This was a cross-sectional study based on data from the Brazilian 2013 National Health Survey.

Methods: The sample consisted of 20,058 men and 20,600 women aged between 18 and 65 years.

Psychosocial and environmental determinants of physical activity in a Brazilian public university employees - ELDAF: A prospective cohort study protocol.

Background: Increased physical activity levels and their determinations are essential issues worldwide. The Longitudinal Study of Physical Activity Determinants (ELDAF) aims to understand the roles of psychosocial and environmental factors in workers' physical activity levels.

Methods: A prospective cohort study of non-faculty civil servants from a public university (approximately 1,200 individuals) will start in 2022 (baseline).
