Clinical neural scaffold for olfactory ensheathing cells

It is known that UV can degrade polymer. Previous studies showed that UV wavelength of 250 nm can cleave poly (methyl methacrylate), a standard polymer to its monomer methyl methacrylate and gases (Srinivasan, Braren, & Casey, 1990). Increasing the duration of the sterilization also increased damage to the polymer structure (Shearer, Ellis, Perera, & Chaudhuri, 2005)Recently, UV has been shown to induce significant degradation of PLGC and P(LLA-CL) nanofibers (Yixiang, Yong, Liao, Chan, & Ramakrishna, 2008). The degradation by UV of electrospun nanofibers can be exploited for the fabrication of 3D nanofibrous scaffolds with micropores. For the ethanol sterilization, the global structure of the fibrous mesh shrank in size, detaching part of the fastened portion of the mesh from the membrane insert Investigation on two different scaffolds showed that ethanol sterilization also resulted in damage to the polymer (Shearer, Ellis, Perera, & Chaudhuri, 2005). Digital image analysis from SEM images, showed that average fibre diameter expanded by 21.1% (EOa= 1.08µm; EOb=0.89 µm) (Error: Reference source not found). ...

Chapter 14 Sterilization and Surface Functionalization 14.1 Sterilization Effect on Fibre Morphology The relative susceptibility to the PLGA and PMMA to the chemical and irradiation steps involved in the sterilization process was studied. The sterilization of fibre mesh mounted membrane insert under three conditions was investigated to determine the effect of each mechanism individually…

Does lupron provide a better outcome for first line treatment in advanced prostate cancer
Introduction In spite of all the dramatic advances in the understanding of disease processes, medical science and medical technologies, cancer remains a disease of special focus in present times, because of the challenges that it continues to pose as a life threatening disease. Most of the cancer diseases tend to be chronic, with a strong possibility of causing the death of the individual, yet take years to develop, before presenting any signs and symptoms of the disease. There is limited clarity in how cancer diseases develop and the exact etiology of most cancers is yet to be clearly...

Calories restriction and health in medical improvement
Fasting prior to chemotherapy enhances the effect of the chemotherapeutic agent on the tumour and reduces the toxic side effects of the chemotherapeutic agent on the patient. However, before this benefit of calorie restriction could be used in human beings more studies are require to reinforce the findings of the twin benefits of calorie restriction. 1. Introduction 1.1. Calories Restriction Over the last seven decades evidence from insect and animal studies has pointed to the restriction of calorie intake resulting in increase in life span. These findings have led to interest developing for a...

One year clinical results of Er, Cr:YSGG laser application in addition to scaling and root planing with early to moderate period
This strategy is aimed at abating, if not eliminating, etiologic agents of the disease, like microbial film and subgingival calculus [14], and restoring periodontal attachment level through the reconnection of periodontal fibers with newly formed cementum [2,52]. For nonsurgical management of early to moderate chronic periodontitis, scaling and root planing (SRP) remains the traditional initial approach of treatment. Scaling removes plaque, calculus and stain from crown and root surfaces while root planing entails the complete debridement of cementum or dentin from the root surface for the...

For instance if one treatment is effective in children, could if be equally as effective with adults. Trials confirm what treatments are being used safely and satisfactorily on individuals. There importance is limitless amongst the population of the medical world. For quite some time, clinical trials in the pharmaceutical industry have been regulated by several government bodies. These regulations are set forth by entities like the United States Food and Drug Administration (FDA), the European Medicines Agency (EMEA or EMA), the International Conference on Harmonization (ICH), and the...

The immune response
The macrophages engulf the pathogen entering the body and with the help of the major histocompatibility complex (MHC) combine with the receptors on the T Cells. The type of pathogen entering the body depends as to where it would be taken by the antigen presenting cells. If it belongs to the group of viruses it would be presented to the CD-8 positive cytotoxic cell whereas if it is a microbe it would be presented to the CD-4 positive helper cells. The T Cells also have to be activated with the help of the lymphokines which are released by both the macrophages and t helper cells. The helper T...
