stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. they are found in multicellular organisms. in mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. in ad...

Next-generation wearables will interface intimately with the human body either on-skin, implanted or woven into clothing. This requires electrical components that match mechanical properties of biological tissues - stretchability...

BACKGROUND Excess fluid (ExF) accumulates in the body in many conditions. Currently, there is no consensus regarding methods that adequately distinguish ExF from fat-free mass. OBJECTIVE The aim was to develop a model to determine fixed hydration constants of primary body tissues enabling ExF to be calculated from whole-body measurements of weight, intracellular water (ICWWB), and extracellul...

Background: Lower extremity injuries are frequently observed in car-to-pedestrian accidents and due to the bumper height of most cars, knee joint is one of the most damaged body parts in car-to-pedestrian collisions.Objective: The aim of this paper is first to provide an accurate Finite Element model of the knee joint and second to investigate lower limb impact biomechanics in car-to-pede...

Hydrogen peroxide solution is commonly used for irrigating and cleaning wounds. It has some germicidal properties and may remove contaminants mechanically. When it is applied to tissues catalase causes its rapid molecular decomposition with the release of oxygen bubbles (1 ml of hydrogen peroxide 3% (10 vol) will release 10 ml oxygen).' Irrigation under pressure or into enclosed body cavities, ...
