Primers are short pieces of DNA that are made in a laboratory. Since they're custom built, primers can have any sequence of nucleotides you'd like. In a PCR experiment, two primers are designed to match to the segment of DNA you want to copy. Through complementary base pairing, one primer attaches to the top strand at one end of your segment of interest, and the other primer attaches to the bottom strand at the other end. Primers are also necessary because DNA polymerase can't attach at just any old place and start copying away. DNA Polymerase is a naturally occurring complex of proteins whose function is to copy a cell's DNA before it divides in two. The DNA polymerase in our bodies breaks down at temperatures well below 95 °C (203 °F), the temperature necessary to separate two complementary strands of DNA in a test tube. Nucleotides are the building blocks that DNA molecules are made of.

Genetics Course|Biology Course Summary This course is based on 7.03 Genetics, Fall 2004 made available by Massachusetts Institute of Technology: MIT OpenCourseWare under the Creative Commons BY-NC-SA license. This course discusses the principles of genetics with application to the study of biological function at the level of molecules, cells, and multicellular organisms, including humans. The topics include: structure and function of genes, chromosomes and genomes, biological variation resulting from recombination, mutation, and selection, population genetics, use of genetic methods to analyze protein function, gene regulation and inherited disease.

Gene Delivery: Tools of the Trade Genes can be delivered into a group of cells in a patient's body in two ways. The first, called in vivo (in VEE-voh), is to inject the vector directly into the patient, aiming to target the affected cells. The second, called ex vivo (ex VEE-voh), is to deliver the gene to cells that have been removed from the body and are growing in culture. Ex vivo approaches are less likely to trigger an immune response, because no viruses are put into patients. Bone marrow contains stem cells that give rise to many types of blood cells. Two Page Version, Dalhousie Immunology Bookcase The Two Page Version The immune system depends on the complex interaction between many diverse elements. It is important to remember that, although it is involved in a number of disease processes, the primary function of the immune system is to combat infectious agents. There are four major components of the immune system involved in fighting off pathogens: 1. Each of these components will be dealt with in detail in this textbook but their important functions are very briefly summarized below. Antibodies specifically bind to pathogens to bring them to the attention of other parts of the immune system (Complement and phagocytic cells). Complement refers to a cascade of small proteins that bind to pathogens and poke holes in their outer surface causing death (Appendix 2). T cells are referred to as CD4+ or CD8+ T cells based on their surface protein markers. Non-specific effector cells have a variety of functions.

Acute Oxygen Prescribing Oxygen therapy. Forever argued by opposing factions throughout the hospital. Traditionally the anaesthetists have always maintained the standpoint that hypoxia is far more detrimental than hypercarbia, and advocated the use of high inspired concentrations of oxygen, at high flows. Opposing this the physicians, particularly chest physicians, have always held firm the opinion that retention of CO2 in chronic type 2 respiratory failure is sufficiently serious an issue to warrant judicious use of oxygen therapy. Since 2008 there has finally been agreement following the publication of the British Thoracic Society Guideline on Emergency Oxygen Therapy in Adults. This guideline is a consensus statement from every royal society throughout the UK (medical, surgical, nursing, anaesthetic, O&G, paramedics, A&E) apart from paediatrics (They have their own guidance). We have a local implementation of this guideline, and you can download it here. Be Sociable, Share!
