However, luminescence lifetime, which is a measure of the transition probability from the emitting level, may be effectively used. It is a characteristic and an unique property and it is highly improbable that two different luminescence emissions will have exactly the same decay time. The best way for a combination of the spectral and temporal nature of the emission can be determined by laser-induced time-resolved spectra. Time-resolved technique requires relatively complex and expensive instrumentation, but its scientific value overweights such deficiencies. It is important to note that there is simple relationship between steady-state and time-resolved measurements. The steady-state spectrum is an integral of the time-resolved phenomena over intensity decay of the sample, namely ... 

We hear a lot these days about the relationships between saturated fats, cholesterol, and heart disease. What are the facts It s well established that a diet rich in saturated animal fats often leads to an increase in blood serum cholesterol, particularly in sedentary, overweight people. Conversely, a diet-lower in saturated fats and higher in polyunsaturated fats leads to a lower serum cholesterol level. Studies have shown that a serum cholesterol level greater than 240 mg/dL (a desirable value is <200 mg/dL) is correlated with an increased incidence of coronary artery disease, in which cholesterol deposits build up on the inner walls of coronary arteries, blocking the flow of blood to the heart muscles. 

The average basal metabolic rate for humans is about 65 keal/h, or 1600 keal/day. Obviously, the rate varies for different people depending ori sex, age, weight, and physical condition. As a rule, the BMR is Jow er for older people than for younger people, is lower for females than for males, and is lower for people in good physical condition than for those who are out of shape and overweight. A BMR substantially above the expected value indicates an unusually rapid metabolism, perhaps caused by a fever or some biochemical abnormality. 

The body mass index (BMI) is a number calculated from a person s weight and height that can be used to estimate his or her level of body fat. A person is classified as healthy, overweight, or obese based on his or her BMI. The BMI value can be helpful in assessing the health risks a person may face because he or she is carrying too much weight. 

Body mass index (BMI) is another index of weight-for-height that is highly correlated with body fat. Interpretation of BMI should include consideration of gender, frame size, and age. BMI values greater than 25 kg/m2 are indicative of overweight, and values less than 18.5 kg/m2 are indicative of undernutrition. BMI is calculated as follows ... 

It is crucial to define a reference configuration, or state, to which all tests can be reckoned. Such a reference state, referred to as hypertonic state, is defined as the state of maximum salinity of the extrafibrillar compartment then as the salt content overweights the presence of proteoglycans, the latter have a very small mechanical effect the hypertonic configuration is such that the stress is equal to the bath pressure. Therefore, stresses and pressures can be reckoned to their values at the hypertonic state from which all tests start and at which by convention the strain vanishes as well. 

Up to one-third of the fatty acids in milk fat have a chain-length of 14 carbons or less. Because these acids are oxidized rapidly in the liver, have a lower energy value and are oxidized more readily than long-chain fatty acids, it follows that milk fat should contribute less to overweight than an equivalent amount of other dietary fats (Parodi, 2004). A study by Schnee-man et al, (2003) showed that milk fat is a more potent stimulator of cholecystokinin than a blend of non-milk fat with a similar ratio of polyunsaturated to saturated fatty acids. Cholecystokinin is a satiety hormone released into the blood stream by the intestine during feeding and acts to suppress further eating. 

The chosen sample size reflects (i) the formal sample size calculation (using a residual variance value of 17.5%) based on the pharmacokinetics of ethinylestradiol in lean subjects, (ii) published sample sizes in other studies of this type of study ranged between 12 and 34, (iii) that this study will include overweight and obese subjects, a population who have been suggested to show a higher variability in their pharmacokinetics and in their menstrual cycles, and finally (iv) the plan not to replace dropouts. 

Normal values range from 22 to 28. Values > 30 are indicative of an overweight condition. Obesity is always the consequence of a disturbed energy balance caloric intake exceeds consumption. Almost unavoidably, excess body weight and obesity lead to diseases and a shortened lifespan. 

The frequency of NAFLD in the general population is given as 3-58%, whereby the great variability is due to socio-economic differences (average value 20-23%). The development of NAFLD is more closely correlated with obesity than with alcohol abuse. In the case of combined obesity and alcohol abuse, the frequency of fatty liver is estimated to be 50-60%. About one third of overweight patients suffer from type II diabetes, which in turn is responsible for the development of an NAFLD or it can lead to the formation of ASH and NASH. Consequently, if several causal factors of... 

Metabolic diseases A fatty liver does not require a low-fat diet, but standard nutrition based on general reference values for normal daily routine. With a normal body weight and an increased energy requirement (work, sports), the calorie intake has to be adjusted accordingly. In overweight patients, a slow, continuous, yet systematic weight reduction should be strived for. Coexistent hyperlipoproteinaemia may require supportive treatment. Diabetes mellitus must be properly eon-trolled. This also applies to concomitant gout. 

It can be seen that the various values of f(a) do not appear in the expression on the same footing—each value of f(a) is multiplied by a factor which varies with the value of a. These factors are termed weights since they determine the contribution made by each term to the average value. Clearly, the quantity f(ao) is heavily overweighted relative to the subsequent quantities f(a ). Furthermore, as the time interval separating a particular value of a from the initial value increases, so the corresponding value of the function f(a) contributes less and less to the average... 

Obesity is defined as an excess of fat tissue in comparison with normal values for age and sex. In order to compare studies, standard definitions of overweight have been proposed. The most frequently used methods of calculation are ideal body weight and body mass index. The former takes height and sex into account and the individual is said to be obese when the actual weight exceeds 120% of the ideal weight. The latter is calculated with the ratio weight/height, and normal values are 23 kg/m for men and 21 kg/m for women. 

Correlation can be done by plotting the specific activity for the new reaction vs the marker reaction (Figure 10.7). In principle, the correlation coefficient estimates the fraction of the variance attributable to the relationship between the two activities, that is, the fraction of the activity catalyzed by the particular enzyme (assuming that all of the marker activity is catalyzed by this enzyme). In some cases, excellent correlations have been reported - An alternative method of analysis is the Spearman rank plot, which has some deficiencies but avoids the overweighting of unusually high or low values. ... 

In general, adults with BMI values below 18.5 are considered underweight. Those with BMls between 18.5 and 24.9 are considered to be in the healthy weight range, between 25 and 29.9 are in the overweight or preobese range, and above 30 are in the obese range.
