Health is a valuable asset not only for an individual, but also for the social system. According to the WHO “promotion of oral health is a cost effective strategy to reduce the burden of oral disease and maintain oral health and quality of life”.1 Microbes have always been responsible for diseases making them an etiology of periodontal diseases. The microbial interaction for periodontal diseases has been under research from the golden age of microbes in diverse cultures of the world. However,…

Introduction It seems to be the common rule that the younger we are when we try to learn something new, the better we are at acquiring the necessary skill. Our human performance is therefore a reflection of the neural circuitry that has been developed by early experiences. Yes, we are capable of learning new things when we are adults; however, it appears that those who have started younger, fare better. This is caused by the fact that we have certain critical or sensitive periods in our early…

present in bone and primarily serve as structural protein of extracellular matrics. The tissues regeneration are often limited by their poor mechanical properties where it can be improved by included the hydroxyapatite compound. The combination of this properties between natural polymer and bioactive ceramic materials make the bone regeneration done smoothly (Maddela Swetha et al., 2010). Collagen is the major components of extracellular matrix such as tendons, ligaments and skin. The…

Duchene Muscular Dystrophy is an inherited neuromuscular disorder of childhood which primarily affects boys characterized by progressive muscle weakness and wasting due to a mutation in the dystrophin gene of X chromosome. Degeneration of muscles usually begins to appear in the lower half of the body then spreading into upper limbs and eventually leading to death. Between 1830 and 1850 scientists reported on an illness where boys grew gradually weaker, lost the ability to walk and died at an…

Interactive Question 7.2 Cite some experimental evidence that indicates that membrane proteins drift. A good form of experimental evidence is Fluorescence Recovery After Photobleaching, aka FRAP. In the FRAP process, membrane proteins are labelled with a green fluorescent protein, and part of the plasma membrane is “bleached” with a laser, causing them to lose their fluorescence. The part that was bleached will eventually become fluorescent again, as molecules drift in by diffusion. How might…

permanently using cell adhesion structures such as pili and receptors called epitopes. This encourages bacterial multiplication and provides convenient sites for adhesion. The bacteria secrete an extracellular slimy substance comprised of proteins, polysaccharides, and nucleic acids to build the protective matrix biofilm structure. The bacteria now communicate by means of quorum sensing and use inducers to regulate gene expression within the bacterium. Quorum sensing is a bacterial mechanism…

cells, and endothelial cells- which live inside the blood vessels. Once inside its cell of choice, the Ebola Virus glycoprotein distributes cell adhesion, which makes the cells have trouble sticking together and stops the cells sticking to the extracellular matrix, which helps hold the cells together (Kelsey, L, 2014). Ebola has many health impacts, one of which being death, but can also lead to internal bleeding, liver damage, and the immune system not working properly. The internal bleeding in…

pressure wound therapy (NPWT) treatment. We hypothesize that the combination of Hyalomatrix® with NPWT will expedite the healing percentage of non-healing surgical wounds. This will be correlated to increase growth factors and interleukins and decrease matrix metalloprotease enzymes collected from the wound in the…

oxidative stress are involved in the spiraling vicious inflammatory cycle. The presence of antioxidant and anti inflammatory properties of γ-Oryzanol from rice bran oil is due to its ability to inhibit eicosanoids production, reduce oxidative stress, matrix metallo proteinases and C-reactive protein in inside the environment of macrophages (Rukkumani et al, 2012). Rice bran could reduce the levels of nitric oxides, Il-1β, Il-6, TNF-α, COX-2 and 5-LOX expressions in mice (Choi et al, 2013).…

Support the Endosymbiotic Theory Gianna Melendez Chamberlain College of Nursing Support the Endosymbiotic Theory The endosymbiotic theory proposes that eukaryotes formed from the union of small aerobic prokaryotes with larger anaerobic prokaryotes, which form organelles. The smaller prokaryotes were not destroyed by the larger cells, but instead became internal parasites that remained surrounded by a vesicular membrane of the host. The theory proposed that mitochondria are the…
