proliferating cells. These cells are known as transient amplifying cells and are formed through the differentiation of HFSCs (Dotto & Cotsarelis‚ 2005). This paper will seek to examine a specific protein within the HFSC known as Ras-related C3 botulinum toxin substrate 1 recombinant protein (Rac 1). Through intrinsic expression‚ Rac1 – a small GTP protein is crucial for the maintenance and the proliferating HFSCs. Through increasing evidence‚ scientists have accredited this to the negative regulation

Bad bacteria like the Clostridium family‚ of botulism fame‚ live in our guts and dine on our Western diets of high fat‚ high sugar and processed foods. These bacteria can produce toxins that are released into the bloodstream and could affect the brain in a bad way. Microbes also play good parts in people’s health. The microbes that normally live in association

Bones in our body are living tissue. They have their own blood vessels and are made of living cells‚ which help them to grow and to repair themselves. Every single person has a skeleton made up of many bones. These bones give your body structure‚ let you move in many ways‚ protect your internal organs‚ and more. As well‚ proteins‚ minerals and vitamins make up the bone. Bones have several parts‚ but are manily made out of calcium deposits. It takes around 20 years for our bones to completely

Tetanus is a medical condition characterized by a prolonged contraction of skeletal muscle fibers. The primary symptoms are caused by tetanospasmin‚ a neurotoxin produced by the Gram-positive‚ rod-shaped‚ obligate anaerobic bacterium Clostridium tetani. Clostridium tetani spores can be found most commonly in soil‚ dust and manure‚ but also exist virtually anywhere. If deposited in a wound the neurotoxin interferes with nerves that control muscle movement. The signs and symptoms of tetanus

Migraines are recognized as a major cause of disability worldwide. Using occupational therapy can help migraine sufferers live a better quality of life without having to rely on medication. The main treatment for migraine sufferers is medication; however‚ occupational therapy can teach migraine sufferers how to live a better quality of life without the use of medications through self-regulation therapy. Migraine sufferers should seek out occupational therapy as an alternative to medications. Occupational

Option F: Microbes and Biotechnology Diversity of Microbe F.1.1 Outline the classification of living organisms into three domains. Three domains of living organisms: 1. Archaea - very primitive; live in extreme habitats 2. Eubacteria - more advanced 3. Eukaryota - all life forms with eukaryotic cells (have a nucleus) Use of ribosomal RNA sequences for classification rRNA is found in all cells rRNA is easy to isolate Analyzed to determine the exact sequence of nucleotide bases

Poisoning You know when eating some kind of food‚ and it doesn’t taste right‚ look right or smell right? That means it could be contaminated with a dangerous substance that could harm the body. Food poisoning is the result of ingesting organisms or toxins in food. Food poisoning can affect one person‚ or it can occur as an outbreak among several people who all ate the same thing. Even though food poisoning is quite rare in North America‚ food poisoning affects 60 to 80 million people each year‚ and
