LH administration as a potential strategy for ovarian protection and female fertility preservation against highly gonadotoxic chemotherapy
2022
Els ovaris contenen una reserva de fol·licles no renovable, que produeixen un únic ovòcit fecundable a cada cicle menstrual al llarg de l'etapa reproductiva femenina (15-49 anys), però que disminueix progressivament amb l'edat. Per tant, els factors que afecten negativament la dotació de fol·licles provocaran una reducció significativa de la vida reproductiva en la dona. Les teràpies oncològiques basades en l'administració de quimioteràpia alquilant s'utilitzen habitualment per a tractar els càncers ginecològics en pacients joves, però amb freqüència acceleren l'esgotament de la reserva fol·licular i l'aparició de la menopausa. Els efectes secundaris de la quimioteràpia sobre la fertilitat,…
DNA extraction from phytoseiid specimens preserved on a glass slide and molecular diagnostic
2010
This study focuses on the diagnostic of seven species of mite belonging to the family of Phytoseiidae; very important biocontrol agents of phytophagous mites. However, they are morphologically very similar and specific diagnostic is very difficult in fact using the traditional identification methods it is uncertain to identify a species especially when Authors use different characters, very often not stable in the time. In the 60’s M.me Athias-Henriot took into consideration the insemination apparatus that is considered a stable character in the time. According to her, the shape of this apparatus could be considered a major criterion for genus distinction. The aim of the present study is to…
Higher Socioeconomic Status Predicts Less Risk of Depression in Adolescence: Serial Mediating Roles of Social Support and Optimism.
2020
Family socioeconomic status (SES) is known to have a powerful influence on adolescent depression. However, the inner mechanisms underlying this association are unclear. Here, we explore this issue by testing the potential mediating roles of social support (interpersonal resource) and optimism (intrapersonal resource), based on the predictions of the Reserve Capacity Model (RCM). Participants were 652 adolescents (age range: 11-20 years old, Mage =14.55 years, SD = 1.82; 338 boys (51.80%)) from two junior and two senior high schools in Wuhan, China. They completed questionnaires measuring family SES, perceived social support, trait optimism, and depression. Results showed, as predicted, (1) …
