Dear Editor, Infertility is a major health problem affecting 10%-15% of couples seeking to have children, and a male factor can be identified in about half of these cases.1 Nonobstructive azoospermia is one of the causes of male infertility （10%）, resulting from testicular failure？ The most common histological patterns in these patients are hypospermatogenesis （HS）, maturation arrest （MA）, and Sertoli cell-only syndrome （SCO）.3

An alternative to the classical extrapolations is proposed. The stability and the accuracy are studied. The new extrapolation behaves better than the classical ones when there are problems of stability. This technique will be useful in those problems where the region of stability is very small and it forces to work with too fine scales.

Transforming growth factor beta 1 (TGF-β1) is a key regulator that modulates male reproductive function. Testicular TGF-β1 modulates the steroidogenesis of Leydig cells, the organization of peritubular myoid cells, testis development and spermatogenesis. Several studies have indicated that TGF-β1 is involved in the tight balance between proliferative and apoptotic responses in the Leydig cells. In the present review, we summarize the direct effects of this cytokine in Leydig cells under normal and pathological conditions. We analyze the effect of TGF-β1 inLeydig cells depending on the type of receptors involved in the signaling pathway of TGF-β1. Our group has been analyzing the canonical and non canonical intracellular signaling pathways of TGF-β1 that are involved in the expression of proliferative and apoptotic markers in Leydig cells. On the basis of our studies and from those of other authors we conclude that the balance between the expression of TGF-β1 receptors and co receptors is of relevance in Leydig cell physiology and pathophisiology.

Next-generation sequencing （NGS） technologies allow the cost-effective sequencing of whole genomes and have expanded the scope of genomics to novel applications, such as the genome-wide characterization of intraspecific polymorphisms and the rapid mapping and identification of point mutations. Next-generation sequencing platforms, such as the Illumina HiSeq2ooo platform, are now commercially available at affordable prices and routinely produce an enormous amount of sequence data, but their wide use is often hindered by a lack of knowledge on how to manipulateand process the information produced. In this review, we focus on the strategies that are available to geneticists who wish to incorporate these novel approaches into their research but who are not familiar with the necessary bioinformatic concepts and computational tools. In particular, we comprehensively summarize case studies where the use of NGS technologies has led to the identification of point mutations, a strategy that has been dubbed ＂mapping-by-sequencing＇, and review examples from plants and other model species such as Caenorhabditis elegans, Saccharomyces cerevisiae, and Drosophila mela- nogaster. As these technologies are becoming cheaper and more powerful, their use is also expanding to allow mutation identification in species with larger genomes, such as many crop plants.

AIM:To profile protein expression in mucosal biopsies from patients with chronic refractory pouchitis following antibiotic or probiotic treatment,using a comparative proteomic approach. METHODS:Two-dimensional polyacrylamide gel electrophoresis and matrix-assisted laser desorption/ ionization-time of flight mass spectrometry were used to characterize the changes related to antibiotic therapy in the protein expression profiles of biopsy samples from patients with chronic refractory *** same proteomic approach was applied to identify differentially expressed proteins in the non-inflamed pouch before and after probiotic administration. RESULTS:In the first set of 2D gels,26 different proteins with at least 2-fold changes in their expression levels between the pouchitis condition and antibiotic-induced remission were *** the second set of analysis,the comparison between mucosal biopsy proteomes in the normal and probiotic-treated pouch resulted in 17 significantly differently expressed *** these,8 exhibited the same pattern of deregulation as in the pouchitis/pouch remission group. CONCLUSION:For the first time,2D protein maps of mucosal biopsies from patients with ileal pouch-anal anastomosis were provided,and differentially expressed proteins following antibiotic/probiotic treatment were identified.

Therapeutic hypothermia is today used in several clinical settings, among them the gut related diseases that are influenced by ischemia/reperfusion injury. This perspective paved the way to the study of hibernation physiology, in natural hibernators, highlighting an unexpected importance of the gut microbial ecosystem in hibernation and torpor. In natural hibernators, intestinal microbes adaptively reorganize their structural configuration during torpor, and maintain a mutualistic configuration regardless of long periods of fasting and cold temperatures. This allows the gut microbiome to provide the host with metabolites, which are essential to keep the host immunological and metabolic homeostasis during hibernation. The emerging role of the gut microbiota in the hibernation process suggests the importance of maintaining a mutualistic gut microbiota configuration in the application of therapeutic hypothermia as well as in the development of new strategy such as the use of synthetic torpor in humans. The possible utilization of tailored probiotics to mold the gut ecosystem during therapeutic hypothermia can also be taken into consideration as new therapeutic strategy.
