Transcriptome-guided breeding for Paspalum notatum: producing apomictic hybrids with enhanced omega-3 content.

Transcriptomics- and FAME-GC-MS-assisted apomixis breeding generated Paspalum notatum hybrids with clonal reproduction and increased α-linolenic acid content, offering the potential to enhance livestock product's nutritional quality and reduce methane emissions A low omega-6:omega-3 fatty acid ratio is considered an indicator of the nutritional impact of milk fat on human health. In ruminants, major long-chain fatty acids, such as linoleic acid (18:2, omega-6) and α-linolenic acid (18:3, omega-3), originate from dietary sources and reach the milk via the bloodstream. Since forages are the primary source of long-chain fatty acids for such animals, they are potential targets for improving milk lipid composition.

[Changes in knowledge, attitudes, and habits of the general population with regard to HIV infection].

Introduction: Knowledge of the social changes related to HIV infection can be helpful in the attempts to design more effecting preventive strategies for this disease. The aim of this study was assess the progress that has occurred in the knowledge, attitudes and habits of the general population in relation to HIV infection between 1997 and 2005.

Methods: With this objective, a multidisciplinary team designed a questionnaire survey containing 64 items, which was validated through a pilot study performed with 100 subjects.
