The purpose of this article was to quantify the exercise load and investigate the influence of physical exercise on adipose tissue in obese women from Bénin. Twelve subjects participated at the study. Six of the subjects trained three times a week for six months. Each training session lasted forty-five minutes. The remaining six women constituted the control group. Biopsy samples of adipose tissue were taken from the same site in the gluteal iliac region at the end of six months and analyzed by histochemistry and electron microscopy. The results showed that all subjects suffered from severe central obesity; lipid content and number of adipocytes were higher among the sedentary woman than among those who exercised. Intense exercise in the latter used more lipids than carbohydrates. We conclude that regular, supervised physical exercise reduces lipid levels and thus induces weight loss.

Background: Obesity is increasingly being recognized as a significant risk factor for the development and worsening of back pain. In order to make possible adjustments to therapies and lifestyle, the relationship must first be understood.
Method: This article attempts to explain the relationship between obesity and back pain based on the existing literature.

Introduction: The strategy of adipose component transplantation has been proposed and widely used in both reconstructive and aesthetic surgery. However, there is no uniform standard for the preparation of component fat, and the volume calculation of liposuction and injection in clinical applications is mostly based on experience. This study aims to analyze the volume of component fat obtained during clinical series.

It has been well documented that cold is an enhancer of lipid metabolism in peripheral tissues, yet its effect on central nervous system lipid dynamics is underexplored. It is well recognized that cold acclimations enhance adipocyte functions, including white adipose tissue lipid lipolysis and beiging, and brown adipose tissue thermogenesis in mammals. However, it remains unclear whether and how lipid metabolism in the brain is also under the control of ambient temperature.

Background: Adipokines, bioactive peptides secreted by adipose tissue, appear to contribute to breast cancer development and progression. While numerous studies suggest their role in promoting tumor growth, the exact mechanisms of their involvement are not yet completely understood.
Methods: In this project, varying concentrations of recombinant human adipokines (Leptin, Lipocalin-2, PAI-1, and Resistin) were used to study their effects on four selected breast cancer cell lines (EVSA-T, MCF-7, MDA-MB-231, and SK-Br-3).
