Telomeres and meiosis in health and disease

Telomeres are important segments of chromosomes that protect chromosome ends from nucleolytic degradation and fusion. At meiosis telomeres display an unprecedented behavior which involves their attachment and motility along the nuclear envelope. The movements become restricted to a limited nuclear sector during the so-called bouquet stage, which is widely conserved among species. Recent observations suggest that telomere clustering involves actin and/or microtubules, and is altered in the presence of impaired recombinogenic and chromosome related functions. This review aims to provide an overview of what is currently known about meiotic telomere attachment, dynamics and regulation in synaptic meiosis.

Wine aroma

Conclusions The progress made in the analysis of volatile wine constituents has led to a better understanding of the complexity of wine aroma.Now many factors influencing wine aroma are not only characterized by their sensory impact, but also by chemical data which in many cases allow a more differentiated approach. By correlating sensory and analytical data headway has been made, especially in the field of wine off-odors. Successful analytical cultivar differentiation based on wine volatiles indicates the importance and possibilities of wine aroma for quality control.
