There are about 6 billion nucleotide letters of a particular sequence in a human cell. The full set is known as the genome. DNA information is found in units called genes. One gene codes roughly for one protein. The proteins perform most of the functions of the body at the cellular level. Examples are digestion, the body's defense against disease, and transporting substances throughout the body. Thousands of proteins

S ome aromas even affect us physiologically" (p. 38). Researchers exploring human olfaction have determined that: faint trace of lemon significantly increases people's perception of their own health. Lavender incense contributes to a pleasant mood -- but it lowers volunteers' mathematical abilities. A whiff of lavender and eucalyptus increases people's respiratory rate and alertness. The scent of phenethyl alcohol (a constituent of rose oil) reduces blood pressure. These findings have contributed to the explosive

infection prevention and control theory, critically discuss the challenges of managing Hepatitis B in the community One of the key public health issues that impacts innumerable individuals worldwide is viral hepatitis. This virus leads to substantial human mortality and morbidity from severe infection as well as chronic sequelae (including cirrhosis and chronic active hepatitis (with regard to hepatitis B, C & D). One among the ten commonest cancers that emerges

Diamond Marian Diamond addressed the nature vs. nurture issue so long debated by researchers and scientists by actually observing the effects of living in different environments on young rats. The beginnings of her research with Donald Head occurred in the 1960's, a time when the brain was not viewed as plastic. When presenting the results of their early research demonstrating a small but significant thicker cerebral cortex in rats raised in

4 months in the placebo group. (P=0.01) [Kyogo et.al] an earlier study by Nestle et.al (1998) had showed promising results. In that study, a small group of renal cancer patients were vaccinated with RNA-transfected dendritic cells. T cell response was noted in most of the treated patients and a follow up study conducted after 19 months showed that 7 out of 10 patients still survived. [Jian et.al, 2008] Other vaccines
