Cytoskeleton

membrane becomes leaky more molecules can pass through the membrane that won 't be controlled by the nucleus. Glycolipids bind to glycoproteins (the extrinsic proteins in the membrane) these are used for cell recognition. The plasma membrane and the cytoskeleton interact closely together, helping to provide shape to the…

RESULTS Lipid Extraction The prediction made was that adipose tissue most likely had the highest lipid content and skeletal muscle had the lowest lipid content when comparing liver, muscle, and adipose tissue. The percent lipid was found to be 30% in liver tissue, 70% in muscle tissue, and 90% in adipose tissue in the samples collected. Protein Extraction and Quantification The absorbance vs concentration curve prepared from the Bradford Protein Assay standards was found to have a linear…

Comparing with other disabilities, diseases, spinal cord injury is a critical disorder in worldwide. Physiology and anatomy The spinal cord(SC) is a grayish-white structure that begins superiorly at the foramen magnum in the skull, where it is continuous with the medulla obolongata of the brain. It terminates at the level of the lower border of the first lumbar vertebra. The spinal cord is located within the vertebral canal of the vertebral column, which is surrounded by three meninges: the…

With natural selection its major driving mechanism, evolution is the change over time in the makeup of genetics of a population. Supported by evidence from many scientific methods, Charles Darwin, in On the Origin of Species, asserts that inheritable variations occur in individuals in a population. In the process known as natural selection, due to competition for limited resources, individuals with more favorable characteristics or phenotypes are more likely to survive and better reproduce,…

• Atherosclerosis is a condition in which cholesterol, calcium and other substances build up in body arteries, blocking the blood flow. • Visceral Fat is fat around organs. Its function is to insulate and protect organs. • Subcutaneous Fat is under the skin. This fat protects and insulate our body. Fat (visceral and subcutaneous) stores energy. • Omega-3 fatty acids have the first double bond on the third carbon counting from the carbon in the methyl end. These are essential fatty acids (our…

The Structure and Function of Monomeric Actin Caroline Lussier The Protein Data Bank is a free, updated archive and resource containing information about the structure of macromolecules including proteins and nucleic acids. This material allows users to better understand and compare the building blocks of life. More specifically, this database can help users to draw conclusions about how large molecule conformations help to determine the direction of drug development. The Protein Data Bank has…

PATH2201 Processes in Disease Media Assignment – Can Probiotics Aid in the Treatment of Coeliac Disease? Elissa Jennifer Watt (z3463000) 21/09/14 Tutor: Melanie Walker Introduction Advances in medical diagnosis and screening have revealed that coeliac disease (CD) is a major health issue across the world, affecting all ages. In Australia, the rate of CD was previously estimated to be around 0.4% (Hovell, et al., 2001). More recent estimates suggest that around 1.2% in men and 1.9% in…

Cilia and the Protection of the Respiratory Tract Introduction Approximately twelve thousand litres of air is inhaled by one person each day containing environmental stimuli including pathogens and particles such as toxic pollutants and allergens. These must be expelled from the body as it may induce airway inflammation and infection, causing airway diseases. Mucociliary clearance acts as an innate defence against these stimuli, where cilia is a part of this mechanism. Cilia, microscopic…

Paclitaxel is unique because it contains a binding site specifically for a microtubule polymer as an anti-cancer agent. Paclitaxel has the ability to polymerize tubulin in the absence of cofactors such as guanosine triphosphate. The microtubule cytoskeleton reacts to paclitaxel by reorganizing, thus allowing stable bundles of microtubules to form. Paclitaxel mitotically arrests cells in the G2/M phase of the cell cycle resulting in the cell being unable to form a normal mitotic spindle…

Occurring mostly in males, Duchenne Muscular Dystrophy is an X-linked disorder that includes progressive muscle weakening caused by an insufficient gene for the production of a protein in the muscles called dystrophin. (Lucas-Heron, 1995) It affects about one in 3600-6000 live male births, making it the most common form of muscular dystrophy. Symptoms are most often noticeable by the time patients reach the age of three to five. The affected males will lose their ability to walk by eight to…
