along their free surface. Lying adjacent to the basal surface of an epithelium is a thin supporting sheet called the basal lamina. This noncellular‚ adhesive sheet consists largely of glycoproteins secreted by the epithelial cells plus some fine collagen fibers. The basal lamina acts a selective filter that determines which molecules diffusing from the underlying connective tissue are allowed to enter the epithelium. The basal lamina also acts as a scaffolding along which epithelial

production of a major protein in bone and connective tissue‚ defects in these genes reduce the amount of collagen in our bodies‚ weakens the connective tissues‚ and creates future problems with the growth of bones. More than ninety percent of all cases of OI come from mutations in the COL1A1 and COL1A2 genes‚ located on chromosome 17 and 7 in the bodies. Both of these genes instruct proteins for collagen assembly. Thus‚ problems on the COL1A1 and COL1A2 genes ultimately create the hallmark of OI‚ brittle

stretching and weakening of the pelvic floor tissues. Being overweight can also contribute. New studies on patients with SUI and prolapses shows that the quality of the collagen in patients who have these conditions is poorer than patients who did not. It is thought that genetics play a major role in the quality of pelvic floor collagen. What this means is that if your Mom and Gran suffered with Stress Incontinence and you’ve had a couple of children the chances are that you could also develop Stress

Lipofuscin binds fat and proteins together in the cells. It accumulates over time and may interfere with cell function. The protein collagen is at the heart of this theory. Collagen‚ akin to the body ’s glue‚ is one of the most common proteins making up the skin‚ bones‚ ligaments‚ and tendons. When we ’re young‚ collagen is pliable. But with age‚ collagen becomes more rigid‚ and it shrinks. That ’s why your skin is less elastic than before (Alston‚ 2008). Aesthetics aside‚ cross-linking

structural function in certain areas‚ like the nose‚ but cannot perform this function to the same extent as dense bones do. Cartilage is made up of a special type of cell called the chondrocyte‚ as well as two materials produced by the chondrocytes‚ collagen fibers and elastic fibers. There are different types of cartilage‚ characterized by the differing ratios of fibers contained within them. In addition‚ cartilage is the only connective tissue in the human body which is not exposed to the blood circulation

Proton: Have a single positive charge (+1). Neutron: Have no charge. Electron: Tiny particles with a single negative charge and very low mass (-1)/determines chemical bonding properties of an atom. Atomic Number: Number of protons in the nucleus. Atomic Mass: Approximate number of protons and neutrons

mammal. After the initial discovery‚ further research led to further evaluation of new grafts that were created the same way. These grafts were synthesized to become a copolymer of collagen and a glycosaminoglycan‚ chondroitin-6-sulfate. Control of the pore size‚ degradation rate and surface chemistry of the collagen scaffold were found to be critical traits for its biological

Everyday heroes for every woman My mother is a devout user of Elemis skincare and one Saturday lunchtime‚ we adventured to our Elemis counter to stock up. Talking to the wonderful staff they talked me through their skincare and one set they had on offer. ELEMIS is proud to donate to Breast Cancer Care every year in the aim to help to be there for people affected by breast cancer. As we are told‚ the vital importance of early detection is essential and can answer people’s questions about breast

Lewis Thomas once said‚ "As a people‚ we have become obsessed with Health. There is something fundamentally‚ radically unhealthy about all this. We do not seem to be seeking more exuberance in living as much as staving off failure‚ putting off dying. We have lost all confidence in the human body" (Scrapbook.com). Diseases found in genes can most likely not be able to be put off‚ as they are heredity‚ in which case they are passed down from their parents‚ or a mutation‚ an irreversible change in the

1 Define and explain asepsis‚ antisepsis and cross infection Asepsis- An environment that is free of harmful microorganisms. An aseptic technique ensures that only uncontaminated equipment and fluids come into contact with susceptible body sites. It should be used during any clinical procedure that bypasses the body’s natural defences. Using the principles of asepsis minimises the spread of organisms from one person to another. Aseptic techniques are used to reduce contamination from microorganisms
