Fertility preservation has always been an important part of reproductive medicine. It acquired a new dimension in the current period Coronavirus crisis. The effects COVID-19 on affected people’s function medium and long term cannot be predicted with certainty. may also by some treatment agents used against COVID-19. vivo, suitable young persons no apparent fertility problems, can made use nonto...

In this letter note we present two new parameter identifiers whose estimates converge in finite time under weak interval excitation assumptions. The main novelty is that, contrast with other finite-convergence (FCT) estimators, our schemes preserve the FCT property when parameters change. previous versions of estimators can track variations only asymptotically. Continuous-time and discrete-time...

Machine perfusion techniques are becoming standard care in the clinical donation and transplantation setting. However, more research is needed to understand mechanisms of protective effects machine perfusion. For preservation related experiments, porcine kidneys acceptable alternatives human kidneys, because their size similar physiology. In this experiment, use slaughterhouse was evaluated wit...

Maintaining and preserving fungal cultures are essential elements of systematics and biodiversity studies. Because fungi are such a diverse group, several methods of cultivation and preservation are required to ensure the viability and morphological, physiological, and genetic integrity of the cultures over time. The cost and convenience of each method, however, also must be considered. We enco...

OBJECTIVE To compare preservation with the division of the splenic vessels in the surgical management of laparoscopic spleen-preserving distal pancreatectomy. DESIGN Bicentric retrospective study. SETTING Prospectively maintained databases. PATIENTS Between January 1997 and January 2011, 140 patients who underwent laparoscopic spleen-preserving distal pancreatectomy for benign or lowgrade...

In 1990's, use of machine perfusion for organ preservation has been abandoned because of improvement of preservation solutions, efficient without perfusion, easy to use and cheaper. Since the last 15 years, a renewed interest for machine perfusion emerged based on studies performed on preclinical model and seems to make consensus in case of expanded criteria donors or deceased after cardiac dea...
