Article Synopsis
  • - The hypothalamic-pituitary-gonadal (HPG) axis regulates reproduction in gnathostomes, involving gonadotropins like FSH and LH that interact with their specific receptors in gonads; however, research on these in chondrichthyes (sharks and rays) is limited.
  • - This study identified gonadotropin and receptor sequences in chondrichthyan genomes, analyzed their structures compared to humans, and built 3D interaction models, emphasizing the role of the receptor hinge for ligand recognition.
  • - Expression analysis showed that FSHR and LHR are active throughout spermatogenesis in various testicular cells, with high levels of FSHR transcripts in testis and

Spermatogenesis is a highly specialized process of cell proliferation and differentiation leading to the production of spermatozoa from spermatogonial stem cells. Due to its testicular anatomy, is an interesting model to explore stage-based changes in proteins during spermatogenesis. The proteomes of four testicular zones corresponding to the germinative niche and to spermatocysts (cysts) with spermatogonia (zone A), cysts with spermatocytes (zone B), cysts with young spermatids (zone C), and cysts with late spermatids (zone D) have been analyzed by nanoLC-ESI-MS/MS.

Introduction: The most commonly used treatment for obstructive sleep apnea syndrome (OSA) is the application of continuous positive airway pressure (CPAP) during sleep. However compliance with this treatment is frequently below 70%.

Methods: The main aim of this study was to evaluate the feasibility of an educational intervention (EI) delivered in phone calls made to OSA patients (n=66) treated with CPAP by a home care provider (SADIR).

The increasing prevalence of adolescent obesity justifies widespread effort and attention of the paediatrician. In order to manage, following points are to be documented: (I) weight status assessed on the basis of body mass index (BMI)split in two levels: obesity grade I: >or=97 ème centile, obesity grade 2: level IOTFC 30; (2) complete anamnesis including age at adiposity rebound and existence of overweight in family; (3) research of associated morbidity and medical risks;(4) assessment of food intake and feeding practice; (5) assessment of physical activity; (6) talk with the adolescent to assess the psychological status, looking after depressive symptoms, anxiety, loss of self esteem. Once the items are documented, it allowed making a plan to manage the obesity in alliance with the adolescent and his family.
