Effects of an exercise program on hepatic metabolism, hepatic fat, and cardiovascular health in overweight/obese adolescents from Bogotá, Colombia (the HEPAFIT study): study protocol for a randomized controlled trial.

Background: A considerable proportion of contemporary youth have a high risk of obesity-related disorders such as cardiovascular disease, metabolic syndrome, or non-alcoholic fatty liver disease (NAFLD). Although there is consistent evidence for the positive effects of physical activity on several health aspects, most adolescents in Colombia are sedentary. It is, therefore, important to implement strategies that generate changes in lifestyle.

Effects of Excitotoxic Lesion with Inhaled Anesthetics on Nervous System Cells of Rodents.

Different anesthesia methods can variably influence excitotoxic lesion effects on the brain. The main purpose of this review is to identify potential differences in the toxicity to nervous system cells of two common inhalation anesthesia methods, isoflurane and sevoflurane, used in combination with an excitotoxic lesion procedure in rodents. The use of bioassays in animal models has provided the opportunity to examine the role of specific molecules and cellular interactions that underlie important aspects of neurotoxic effects relating to calcium homeostasis and apoptosis activation.

Neuroglial Cell Cryopreservation in Appropriate Inductive Conditions.

An ability to store cells (if they cannot be used fresh) reduces cell wastage, thereby increasing the supply of transplantable material. Cell storage is also valuable in scientific research, allowing material to be archived and experiments to be repeated from the same tissue source and facilitating research collaboration by allowing stored samples to be distributed. Cryopreservation is currently considered the most promising and successful, long-term biological conservation method.

Nanotechnology in Neurosciences: An Approach.

The use of nanotechnology in neurosciences has been evolving since new treatments, diagnoses and biomolecule monitoring are needed to find safer treatments for central nervous system diseases (CNDs). Nanotechnology employs devices that interact with biological systems allowing molecular interactions with a high degree of specificity. This review considers concepts associated with nanotechnology and leading areas of neurosciences with nanotechnology research.

Pubertal Stage, Body Mass Index, and Cardiometabolic Risk in Children and Adolescents in Bogotá, Colombia: The Cross-Sectional Fuprecol Study.

This study explored the association between pubertal stage and anthropometric and cardiometabolic risk factors in youth. A cross-sectional study was conducted in 2877 Colombian children and adolescents (9-17.9 years of age).

Evidence-based practice: beliefs, attitudes, knowledge, and skills among Colombian physical therapists.

Objective: The main purpose of this study was to describe a group of Colombian physical therapists' beliefs and attitudes towards Evidence-Based Practice (EBP), their education, knowledge and skills for implementing EBP, the use of relevant literature in clinical practice, access to and availability of scientific information and perceived barriers to including EBP in practice.

Methods: This was a cross-sectional study which involved 1,064 Colombian physical therapists. The study used a 50-item screening questionnaire EBP developed to estimate attitudes, beliefs, knowledge and skills regarding.
