Cholesterol is an important biological molecule with many important functions. However, high serum cholesterol is a health hazard. Thus analysis of cholesterol is important and many analytical techniques have been developed. The objectives of the proposed research are to develop an economical, rapid method for the determination of total cholesterol with good selectivity and enhanced sensitivity. For evaluation of proposed flow injection analysis with peroxyoxalate chemiluminescence (FIA-POCL) method, figures of merit such as accuracy, precision, and linear dynamic range will be assessed. The proposed procedure was then applied to the determination of total cholesterol in foods. The procedure was linear …

Objective:
To compare accuracy and throughput time for the measurement of HDL and LDL cholesterol by manual precipitation and fully automated enzymatic methods.
Methods:
Fifty, serum samples collected over a 4 months period (February - May 2004) were analyzed for HDL and LDL cholesterol by two different methods i.e. precipitation manual and automatic enzymatic method in the section of chemical pathology, Department of Pathology and Microbiology, Aga Khan University Hospital, Karachi Pakistan.
Results:
The mean standard deviation for HDL Cholesterol by precipitation method and automated method were 43.12 +/- 8.97mg/dl and 43.86 +/- 10.34mg/dl respectively (p-value = 0.301). The …

A medical treatment is said to have placebo effects if patients who are optimistic about the treatment respond better to the treatment. This paper proposes a simple test for placebo effects. Instead of comparing the treatment and control arms of a single trial, one should compare the treatment arms of two trials with different probabilities of assignment to treatment. If there are placebo effects, patients in the higher-probability trial will experience better outcomes simply because they believe that there is a greater chance of receiving treatment. This paper finds evidence of placebo effects in trials of antiulcer and cholesterol-lowering drugs.

Heart disease is the number one killer in the United States (American Heart Association, 2005). The purpose of this study was to demonstrate the results of a twelve-week exercise program on coronary heart disease risk factors in full-time hospital employees. Methods: The participants were given cardiovascular, weight training, and flexibility recommendations to follow during a twelve-week period. The main heart disease risk factors measured before and after the completion of the exercise program were blood pressure, total cholesterol, HDL-cholesterol, and body mass index. The information was put into the Framingham Heart Score to estimate the participants’ 10-year risk of developing …
