sympathetic nerves that causes constriction of smooth muscles. The second part of the primary hemostasis is the platelet plug‚ which has three different parts: adhesion‚ aggregation‚ and secretion. Adhesion is the platelets attaching to the subendothelial collagen. Aggregation is the platelets sticking together. Secretion of thromboxane‚ platelet phospholipids‚ von Willebrands factor‚ and platelet dervided growth factor all help form the platelet plug. Thromboxane causes vasoconstriction and further platelet

Scurvy: How Can Science Help Prevent Dietary Deficiency Diseases? An Introduction ….. Scurvy is a disease which is caused by a deficiency of Vitamin C. A lack of vitamin C interferes with collagen synthesis which is the formation of the body’s tissues. When the body cannot generate collagen the tissue deteriorates. This causes a range of symptoms such as: * Gum disease * Anaemia * Pains in the muscles * Pain in the joints (Scurvy: NHS) Vitamin C can be found in citrus fruits

The term oxidative stress has been often used to indicate the outcome of oxidative damage to biologically relevant macromolecules such as: nucleic acids‚ proteins‚ lipids and carbohydrates. This occurs when oxidative stress-related molecules‚ produced in the extracellular environment or within the cell exceed cellular antioxidant defenses (Cadenas‚ 1989). Molecular oxygen can easily accept unpaired electrons giving rise to a group of partially reduced species‚ generally termed ROS. The ROS include:

Chapter 4 Tissue: The Living Fabric 4.1 What are tissues? * Groups of cells that are similar in structure and perform a common or related function * There are four basic types of tissues: 1) Epithelial (covering) 2) Connective (support) 3) Muscle (movement) 4) Nervous (communication and control) * The study of tissues is known as histology 4.2 Preparing Human Tissue for Microscopy Requirements * Specimen must be fixed (preserved) * Specimen must be

I personally think that the person who creates the cure for stretch marks is going to be the richest person on the planet. Unfortunately‚ I don’t think it’s going to happen any time in the near future. While technology continues to advance‚ we have yet to find a way to rid ourselves of those rigged looking scars. Now‚ that’s not to say there aren’t effective treatments out there that can reduce the appearance of these unsightly scars‚ but you’d be hard pressed to find an absolute cure. Contrary

aids to fight wrinkles‚ anti-aging and fine lines. Apart from that‚ it helps to maintain an even skin-tone by keeping discoloration and dark circles at bay. As one starts aging‚ the production of collagen reduces‚ which is the main culprit behind all these issues. So this cream helps to restore the collagen. It not only cures the present problems in skin‚ but also prevents from future occurrences‚ if

Syneresis - the process by which a liquid is separated from a gel owing to further coagulation Saturated fat: It comes mainly from animal food products at a normal room temperature. HDL cholesterol: Lipoproteins‚ which are combinations of lipids (fats) and proteins‚ are the form in which lipids are transported in the blood. HDL cholesterol is considered the "good" cholesterol. The higher the HDL cholesterol level‚ the lower the risk of coronary artery disease. Triangle test- A sensory-based

Patella dislocation most commonly occurs when the patella‚ a large sesamoid bone‚ shifts laterally out of the femoral trochlear (Mackay et al. 2014). This may happen due to a direct trauma‚ such as unusual shear force‚ which may occur whilst playing sport or exercise. However‚ it may also occur indirectly due to biomechanical variance‚ such as an increased quadriceps angle‚ trochlear dysplasia or general patella instability (Cheng et al. 2014). The main mechanism involved in a dislocation is a sudden
