The "ram effect" (RE) is an inexpensive technique that allows farmers to obtain out-of-season lambs. Five hundred and ninety-six Corriedale ewes were used in three experiments to determine the effectiveness of different medroxyprogesterone (MAP) treatments associated with the ram effect during the nonbreeding season. The aim of the first experiment was to(More)
OBJECTIVE To evaluate how the lipid profile associates with apolipoprotein (apo) E gene polymorphism, plasma adiponectin level, and body mass index (BMI) z score in Portuguese youth. DESIGN Transversal cohort study. SETTING Hospital de São João and Hospital de Crianças Maria Pia, Porto, Portugal, between May 2006 and March 2007. PARTICIPANTS One(More)
Bovine cysticercosis is a zoonotic infection widely spread throughout Brazil, creating a burden on hygiene maintenance and the economy. Diagnosis of cysticercosis usually relies on post mortem inspection of carcasses in slaughterhouses. This detection method provides only low sensitivity. Recent advancements have improved the performance of serologic tests,(More)
This study focused on estimating the herd-level and animal-level prevalences, and identifying risk factors associated with bovine cysticercosis in the State of Paraíba, Northeastern Brazil. The state was divided into three sampling strata: Sertao, Borborema and Zona da Mata/Agreste. For each sampling stratum, herd-level and animal-level prevalences were(More)
The objective of this study was to analyze thoraco-abdominal kinematics in obese children in seated and supine positions during spontaneous quiet breathing. An observational study of pulmonary function and chest wall volume assessed by optoelectronic plethysmography was conducted on 35 children aged 8-12 years that were divided into 2 groups according to(More)
The aim of this survey was to identify spatial clustering of bovine cysticercosis-positive herds in the state of Paraíba. The state was divided into three sampling groups: sampling stratum 1 (Sertão mesoregion), sampling stratum 2 (Borborema mesoregion) and sampling stratum 3 (Zona da Mata and Agreste mesoregions), and 2382 cows aging ≥ 24 months from 474(More)
INTRODUCTION A significant gap between the number of individuals who need mental health care and the ones who actually have access to it has been consistently demonstrated in studies conducted in different countries. Recognizing the barriers to care and their contributions to delaying or preventing access to mental health services is a key step to improve(More)

This work was aimed at the study of the chemical composition in phenolic compounds responsible for the high antiacetylcholinesterase activity of aqueous extracts (decoctions) from Helichrysum stoechas aerial parts. Chlorogenic acid, cynarin, and arzanol were the main components of decoctions, detected by high-performance liquid chromatography with(More)
