Chronic Diseases Cancer is a group of diseases that deal with the uncontrolled growth of cells. A tumor refers to a collection of abnormal cells; some of them are known as benign tumors. Benign tumors do not become a cancer unless they start spreading and growing. Once these tumors begin to grow and multiply they become a cancer. There is screening for cancer available but only colon‚ breast‚ cervical and prostate cancer screenings have been known to be effective. Colon cancer or colorectal cancer

Why serial dilutions are preferred to one large dilution in lab experiments? Answer: Serial dilution is the technique of performing repeated dilutions on the same chemical in order to change its concentration. The diluted solution from a serial dilution can be used to calculate the concentration of the actual solution. In experimental work‚ often we need to obtain a range of concentrations for a specific compound. Thus‚ instead of preparing one large dilution‚ if we take a concentrated sample of a

Serial Dilution Activity Many applications require the determination of microbial numbers. Those applications can be either clinical or in a research setting. Clinical applications include determination of antibiotic efficacy and as well as therapy. Research applications include determination of the effectiveness of antimicrobial chemicals‚ radiation‚ etc. The viable count is most common or standard method used to quantitate bacteria. With this method only microbes that are alive and able to reproduce

Celiac Disease Etiology: The exact cause of celiac (coeliac disease‚ celiac disease or celiac sprue) is still not fully understood. The majority of those with Celiac have one of two types of a protein called HLA-DQ‚ they will have either DQ2 or DQ8‚ which is inherited in families. The reason these genes make the person more at risk of the disease is that the receptors formed by the genes bind to gliadin peptides more tightly and are more likely to activate and initiate the autoimmune process.

the contention that psychology has almost always been concerned with studying human cognition. The philosophers who most influenced the development of psychology as a science all sought to explain human cognition. Give examples of early efforts (before 1950) to study human cognition experimentally Fechner study cognitive events (sensations) experimentally. Ebbinghaus study learning and memory experimentally. William James cited considerable research on cognition and suggested many additional

PROBLEM Coronary Artery Disease or Coronary Heart Disease (CAD/ CHD) is the primary cause which leads to the majority of all problems of the heart (AHA). More than 600‚000 Americans suffer from Coronary Heart Disease (CHD) ("Coronary heart disease" 2012). In order for an individual to be diagnosed with CAD there has to be a significant amount of plaque buildup which in time‚ if not treated could lead to atherosclerosis‚ the narrowing of arteries. (CDC‚ AHA). This disease has been established as
