CAG and GGN repeat polymorphisms in the androgen receptor gene of a Chilean pediatric cohort with idiopathic inguinal cryptorchidism.

Background: Cryptorchidism is one of the most common congenital disorders in boys and it is associated with a higher risk of sub-fertility and testicular cancer. Testicular descent occurs during embryo-fetal development in two phases, transabdominal and inguino-scrotal. In the latter process, androgens play a leading role.

Drug Resistance of Mycobacterium tuberculosis Complex in a Rural Setting, Angola.

We found high prevalence rates of multidrug-resistant tuberculosis among retreatment patients (71.1%) and persons with new cases (8.0%) in Angola.

Real-time accumulative computation motion detectors.

The neurally inspired accumulative computation (AC) method and its application to motion detection have been introduced in the past years. This paper revisits the fact that many researchers have explored the relationship between neural networks and finite state machines. Indeed, finite state machines constitute the best characterized computational model, whereas artificial neural networks have become a very successful tool for modeling and problem solving.

STR data for nine Y-chromosomal loci in Guinea Equatorial (central Africa).

Allele and haplotype frequencies for nine Y-specific STR loci (DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS393, DYS434, DYS437, and DYS439) were obtained from a sample of 57 males from Guinea Equatorial.
