Heart failure is an important medical, social and economic problem around the world. In recent years, a number of diagnostic prognostic biological markers blood in cardiovascular diseases have been studied. Identification new markers, analysis their pathophysiological aspects changes concentration under influence various treatment options, allow us to understand many pathogenetic features devel...

Crude oil samples recovered from three oilfields distributed within the central Niger Delta were used to investigate biological marker fingerprints, sources of organic matter, conditions deposition, and thermal maturation. This was achieved by application gas chromatography-mass spectrometric (GC-MS) analyses on saturated components crude oils. The ratios show low sterane/hopane (steranes/hopan...

3H-spiroperidol binding to lymphocytes has been proposed as a vulnerability marker for schizophrenia. However, the biological significance and even existence of this "binding site" are still in controversy. Therefore, the present study reevaluated methodological details using a filtration binding assay. The results indicated that some well-known, but obviously uncontrolled pitfalls might contri...

It is time-consuming to process and compare the clinical and marker information registered during monitoring of breast cancer patients. To facilitate the assessment, we developed a computer program for interpreting consecutive measurements. The intraindividual biological variation, the analytical precision profile, the cutoff limit, and the detection limit for each marker are entered and stored...

According to the National Health Interview Survey from 2011, 52% of adults over the age of 18 in the United States are regular drinkers [1]. However, because of the difficulty of defining alcoholism scientifically, there are few widespread statistics regarding the proportion of this group who are problem drinkers. This brings us to the field of science. Scientists have wanted to set a biologica...
