  • Dentin Adhesion Essay

    INTRODUCTION : The concept of dentin adhesion presently used involves the nanomechanical retention which is due to polymerisation of hydrophilic monomers around acid exposed collagen fibres.1 The entanglement of these monomers within the exposed collagen fibres gives rise to the so called Hybrid layer , which is also referred as Resin infiltrated Dentin layer.2 The presence of hybrid layer is important for attainment of a leakage free interface between the cavity walls and resin composite.2 After acid etching, the demineralized collagen matrix is present in a denatured state, beneath which lies the residual hydroxyapatite crystals.3 Monomer infiltration throughout the thickness of demineralised dentin is important for successful adhesion.…

  • Human Skeletal System Essay

    possible to increase again later in life. Mutations in the COL1A1, COL1A2, CRTAP and P3H1 genes is the cause of osteogenesis imperfecta. Most of the mutations that cause OI type I occur in the COL1A1 gene. These genetic changes reduce the amount of type I collagen produced in the body, which causes bones to be brittle and to fracture easily. The mutations responsible for most cases of osteogenesis imperfecta types II, III, and IV occur in either the COL1A1 or COL1A2 gene. These mutations…

    body, along with vertebral remodelling, when administered monthly intravenously to children and adolescents (aged 0.6-18 years). Subjects also reported an improvement in pain and mobility with few side effects (Åström 2002). Bisphosphonate treatments are not a completely flawless or flushed out solution and remain in trial stages, however; they do represent a hopeful path to pursue. Presently, medical treatments for osteogenesis imperfecta at best achieve symptomatic improvement. The only way to…

  • Helical Structure Of Antlers

    Bones tend to have specific interior fluids, but antlers remove their fluids and minerals from the rest of the body in order to grow. They contain large amounts of calcium and phosphorous. They have a mineral content of about 50%, which is very close to the mineral content of bone at 60%. They also consist of osteons that have a laminated structure of concentric rings that contain aligned collagen fibrils. Tusks and Teeth These are the most mineralized components found in organisms. They have 3…

  • Carbohydrate And Fat Essay

    Carbohydrate and fat are the other macro nutrients that provide calories. They play important roles in wound healing. Carbohydrates break down into glucose, the major fuel for collagen synthesis. Carbohydrate will still make up 50-60% of the diet. This is important since glucose is the body’s main source of energy for healing and for cell repair and for proper brain function. Some fat is also essential in every diet. Typically, the recommend amount of total fat is 30%. Unsaturated fat such as…

    that break by even the slightest touch. According to an article, osteogenesis imperfecta “rare genetic disorder that in the large majority of cases is caused by mutations in genes that code for collagen type I” Brittle bones disease is a relatively rare disease affecting close to 1 in every 30,000 live births or 1 in every 60,000 live births for OI Type II. There are 4 different genes that produce the collagen needed for healthy bone development. These genes, if defective, can cause 8 variations…

  • Case Study Of Idiopathic Pulmonary Fibrosis (IPF)

    IPF fibroblasts naturally express higher levels of PDGFR and FGFR than the controls. The proliferative effects of PDFG-BB and bFGF, along with VEGF, were curtailed by the drug. MMPs are endopeptidases that degrade proteins of the ECM, and TIMP are their inhibitors. As expected, treatment enhanced the expression of pro-MMP-2 protein and repressed the expression of the TIMP-2 protein. Transforming growth factor-beta (TGF-beta) is a stimulator of collagen production and upregulates collagens in…

  • Diabetic Foot Ulcer Summary

    Review of “A Clinical Trial of Integra Template for Diabetic Foot Ulcer” Summary: Diabetic foot ulcer is happening due to complications involving the slow healing process as a result of the diabetes. The diabetic foot ulcer is cause by diabetes mellitus which increases risk for diabetic foot ulcer. (Driver et al 891) Diabetic foot ulcer can eventually lead to amputation if not treated or if it is too advanced. now there’s a way to treat foot ulcers using synthetic skin grafts. using a bilayer of…

  • Analysis Of Ambilool And Oxidized Amylose

    Figure 1 shows the photographs of collagen, LAC, LOA1C, LOA2C, LOA3C, LOA4C. It can be seen the LAC looks same with collagen. Meanwhile, with the increase introduction of oxidized amylose the sample’s surface firstly became non-uniform (sample LOA1C, LOA2C) and then inclusion complex/collagen wound dressing looks like sponge foam and more uniform. The presence of oxidized amylose can lead to microphase separation with collagen. So compared with collagen base the little amylose inclusion complex…

  • Implications Of Joint Hypermobility

    Collagen is the fundamental protein found in skin and other connective tissues. Just as the Ehlers-Danlos syndrome is found in the skin, joints and blood vessels. If the collagen is found in the joints Collagen is used a lot in the cleaned form for cosmetic surgical treatments. Vitamin C plays a crucial role in the development of collagen by beginning chemical changes that give lysine and proline to unite in sync as "collagen subunits". Therefore, adding architectural balance to the "complete"…
