An Interdisciplinary Approach to Study the Performance of Second-generation Genetically Modified Crops in Field Trials: A Case Study With Soybean and Wheat Carrying the Sunflower HaHB4 Transcription Factor.

Research, production, and use of genetically modified (GM) crops have split the world between supporters and opponents. Up to now, this technology has been limited to the control of weeds and pests, whereas the second generation of GM crops is expected to assist farmers in abiotic stress tolerance or improved nutritional features. Aiming to analyze this subject holistically, in this presentation we address an advanced technology for drought-tolerant GM crops, upscaling from molecular details obtained in the laboratory to an extensive network of field trials as well as the impact of the introduction of this innovation into the market.

Seminal plasma hexosaminidase in patients with normal and abnormal spermograms.

Background: Glycosidases profusion in male reproductive fluids suggests a possible relationship with sperm function. Although Hexosaminidase (Hex) is the most active glycosidase in epididymal fluid and seminal plasma, as well as in spermatozoa, Glucosidase is considered a marker for epididymal function and azoospermia.

Objective: The aim of this study was to determine Hex activity in seminal plasma from patients with normal and abnormal spermograms and analyze its correlation with seminal parameters.
