Validation of artificial neural network models for predicting biochemical markers associated with male infertility.

Unlabelled: Seminal fluid is the secretion from many glands comprised of several organic and inorganic compounds including free amino acids, proteins, fructose, glucosidase, zinc, and other scavenging elements like Mg(2+), Ca(2+), K(+), and Na(+). Therefore, in the view of development of novel approaches and proper diagnosis to male infertility, overall understanding of the biochemical and molecular composition and its role in regulation of sperm quality is highly desirable. Perhaps this can be achieved through artificial intelligence.

Screening, production, optimization and characterization of β-glucosidase using microbes from shellfish waste.

An extracellular β-glucosidase was isolated from Proteus mirabilis VIT117 found to be growing on prawn shells. The enzyme production was found to be enhanced (14.58 U/ml) when the culture was maintained at pH 9 and provided with sorbitol as carbon source, yeast extract as nitrogen source and incubated at 37 °C for approximately 72 h.

An open, parallel group comparison of quinapril and captopril, when added to diuretic therapy, in the treatment of elderly patients with heart failure.

This study aimed to compare the efficacy, tolerability and first-dose blood-pressure response of once-daily quinapril and twice-daily captopril when added to diuretic therapy in elderly patients with heart failure. The study was performed at a single centre as an open randomised parallel-group study, patients being selected for inclusion from the outpatient population. Following a starting dose of either 2.
