AN ALTERNATIVE MODEL FOR TEACHING TENDON REPAIR AND SURGICAL TECHNIQUE IN HAND SURGERY.

Introduction: At the beginning of the medical career, the orthopedic surgeon in academic training needs valid methodologies for training complex surgeries in tissues that simulate real situations. With training in animal tissue, adapted to approach human tissue, it is possible to simulate procedures and decisions that will be necessary in real situations.

Objective: This study consists in presenting a simple and reproducible simulation model for surgical repair of tendons by training on fresh tendons fixed on a wooden frame.

Laser Microdissection of Woody and Suberized Plant Tissues for RNA-Seq Analysis.

An accurate profile of gene expression at a cellular level can contribute to a better understanding of biological processes and complexities involved in regulatory mechanism of woody plants. Laser microdissection is one technique that allows isolation of specific, target cells or tissue from a heterogeneous cell population. This technique entails microscopic visualization of the selected tissue and use a laser beam to separate the desired cells from surrounding tissue.

Improving Sampling Efficiency for Determining Pediatric HIV Prevalence in National Surveys: Evidence From 8 Sub-Saharan African Countries.

Background: Measurement of mother-to-child HIV transmission through population-based surveys requires large sample sizes because of low HIV prevalence among children. We estimate potential improvements in sampling efficiency resulting from a targeted sample design.

Setting: Eight countries in sub-Saharan Africa with completed Population-based HIV Impact Assessment (PHIA) surveys as of 2017.
