Environmental endocrine disruptors (EEDS) are those endocrine modifying chemicals that are also environmental pollutants. A brief description of known and suspected effects of these chemicals is presented along with a table of chemicals that are of interest for further study by three organisations. The future challenge to environmental chemists will be to develop sensitive, selective, and accur...

Human immunodeficiency virus infection / acquired immunodeficiency syndrome (HIV/AIDS) is a disease pertained to the human immune system. Given its crucial role in viral replication, HIV-1 protease (HIV-1 PR) is a prime therapeutic target in AIDS therapy. In this regard, the dynamic aspects of ligand-enzyme interactions may indicate an important role of conformational variability in HIV-1 PR in...

Children and adolescents interact in peer groups, which are known to influence a range of psychological behavioral outcomes. In developmental psychology related disciplines, social cognitive mapping (SCM), as implemented with the SCM 4.0 software, is most commonly used method for identifying groups from report data. However, series four studies, we demonstrate that has an unacceptably high risk...

The objective of the present study was to improve the detection of B. abortus by PCR in organs of aborted fetuses from infected cows, an important mechanism to find infected herds on the eradication phase of the program. So, different DNA extraction protocols were compared, focusing the PCR detection of B. abortus in clinical samples collected from aborted fetuses or calves born from cows chall...

In this chapter, we propose an ensemble of face detectors for maximizing the number of true positives found by the system. Unfortunately, combining different face detectors increases both the number of true positives and false positives. To overcome this difficulty, several methods for reducing false positives are tested and proposed. The different filtering steps are based on the characteristi...
