Essays on Osteomyelitis

Osteomyelitis is a serious bone infection, occurring rarely, that metastasizes to the bone through the bloodstream. Additionally, surgery or open fracture can also cause the bone infection. Normally, bones do have enough resistance power to evade the infection, but the introduction of microorganisms hematogenously from surrounding structures or direct immunization concerning a surgery can trigger the disease. The persistence of infection for a long time span is referred to as chronic osteomyelitis. Studies over the years have put forward some important factors in the pathogenesis of the disease. These include immunity level of the host, type and location of ...

- Describe the role of the following in protein synthesis - DNA, nucleotides, RNA, ribosomes, rough ER, and Golgi apparatus. DNA or deoxyribonucleic acid is a double stranded hereditary molecule containing the genetic code from which specific protein molecules are synthesized. First step in protein synthesis is synthesis of single stranded complementary RNA. RNA also contains all the components of DNA except a ribose sugar. Special RNA called messenger RNA (mRNA) carries the message to ribosomes. Under mRNA’s direction, transfer RNA (tRNA) delivers amino acids to ribosomes and ribosomal RNA (rRNA) attaches each amino acid to form the final ...

A condition affecting the system of veins in legs with venous hypertension resulting in different pathologies that involve swelling, ulcerations, pain, skin changes, and edema is called chronic venous insufficiency (Eberhardt and Raffetto, 2005). It is necessary to understand normal venous function and anatomy to analyze the venous insufficiencies pathology. The peripheral venous system serves as a conduit returns blood into the heart and as a reservoir where blood is stored. Appropriate operation of the peripheral venous system is dependent on a series of muscle pumps and valves (Eberhardt and Raffetto, 2005). Blood entering the venous system of lower extremities has ...
