(A)Wound healing is a biological process occurring in the human body. In this lecture we had discussed about both acute and chronic wounds. An acute wound is an injury to the skin that occurs suddenly rather than over time. It heals at a predictable and expected rate according to the normal wound healing process. The chronic wounds do not heal in an orderly set of stages and in a predictable amount of time the way most wounds do. The normal wound healing process mainly consists of four main

Role of Helicobacter pyroli derived factors in cell cycle alteration of the gastric epithelial cells: H pyroli infection relatively increases the risk of gastric adenocarcinoma and mucosa associated lymphoid tissue (MALT) lymphoma. H pyroli comprises of a heterogeneous consortium of bacterial strains which show differences in their genotype and phenotypes. Most importantly H pyroli is grouped into virulent and less virulent groups. Virulent group comprises of the type I strain which are Cag A +

Priotities of Gene Therapy Gene therapy is a relatively new area of medicine that attempts to apply recent advances in molecular biology, genetics and biotechnology to the treatment of human diseases. Gene therapy uses a set of approaches to the treatment of human disease based on the transfer of genetic material (DNA) into an individual. Gene delivery can be achieved either by direct administration of gene-containing viruses or DNA to blood or tissues, or indirectly through the introduction

Surgery has been around for thousands of years. Ever since man has felt pain, man has looked to surgery for relief. It started as a crude hole in the skull, and has evolved into techniques using lasers and robots. One cutting-edge present technology that this paper will explore is the da Vinci Surgical Robotic System [1], which is being used at Johns Hopkins [2]. This system performs minimally invasive cardiac surgery; it makes the cuts more precise and saves lives. In the future, robotic surgery

harmony with desired repair or regeneration process, whereby, by-products are metabolized or excreted from the body without eliciting an inflammatory response. Bioactivity/gene delivery Act as a cell carrier or control the release of growth factors, transfection vectors and/or genetically modified cells. Mechanical integrity and integration Sufficient to support or match surrounding native tissue at site of implantation, as well as mediate mechanical stimulus to cells during loading. Structural anisotropy

The technique and detail parameter was subtracted from the paper directly used as a instruction and reference. 1. Discuss in detail the effects that an activating mutation in the IKBKB gene would be expected

In today’s world, many infants are allergic to certain proteins naturally present in cow’s milk. Due to the huge volume of milk products consumed by the human race, there is a need to get rid of this allergy-causing protein and eliminate this allergic reaction. AgResearch has investigated ways to manipulate the genetic material in dairy cattle by using the process of ‘Gene Knockdown’, with the aim to create a cow which produces milk which doesn’t contain the protein responsible for the allergic reactions

Andrew Wilson The suitability of the use of animal models and SiRNA Technologies in autosomal dominantly inherited neurodegenerative disease Dr P Martin Biomedical Science Abstract: The treatment of dominantly inherited neurodegenerative disease has been not feasible until recent discovers of gene therapy. Discovers such as short interfering RNA (siRNA) which cause gene silencing due to the molecule forming a complex with messenger RNA (mRNA), resulting in the degradation of mRNA through pathways

single stranded RNA and DNA production and a host of other manipulations. Cloning of any DNA fragment essentially involves four steps # fragmentation - breaking apart a strand of DNA # ligation - gluing together pieces of DNA in a desired sequence # transfection - inserting the newly formed pieces of DNA into cells # screening/selection - selecting out the cells that were successfully transfected with the new DNA Although these steps are invariable among cloning procedures a number of alternative routes

Abstract In 1979 Nobel prize laureate and the co-discoverer of the structure of DNA called for a precise method to gain control over specific classes of neurones “leaving the others more of less unaltered” which will allow us to understand more about the “profoundly mysterious brain.” This was the first articulated idea of optogenetics, which would lead to the development of one of the most exciting areas of neuroscience. In 2005 Karl Desseroth and Ed Boyden publishes a paper detailing a single optogenetic
