Psychological evaluation of candidates for the uterus transplantation French trial.

Introduction: Since 2017, women with absolute uterine infertility due to Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome have been eligible to participate in a uterine transplantation clinical trial conducted by Foch Hospital in France. The aim of this study is to assess the psychological state of potential candidates, including recipients, their partners, and their living-related donors.

Material And Methods: Sixteen potential uterus transplant candidates, including recipients, partners, and living-related donors, participated in the study.

[Epidemiologic and histopathologic characteristics of 1280 uterine cervical cancers in Kinshasa].

Objective: Due to the lack of both cancer registry and large scale cervical screening in most african countries, only theoretical studies are available. The objective of our work was to provide epidemiological and histopathological characteristics of cervical cancer based on concrete observations.

Methods: This study was carried out on all cancers (n=5801) collected in the last 10 years from 5 pathology laboratories of Kinshasa; the histologic slides of the cervical cancers (n=1280) were reviewed by at least two pathologists and classified according to the 2014 OMS classification.

Power of protein/tRNA functional assembly against aberrant aggregation.

Understanding the mechanisms of protein oligomerization and aggregation is a major concern for biotechnology and medical purposes. However, significant challenges remain in determining the mechanism of formation of these superstructures and the environmental factors that can precisely modulate them. Notably the role that a functional ligand plays in the process of protein aggregation is largely unexplored.

A chemical chaperone induces inhomogeneous conformational changes in flexible proteins.

Organic osmolytes also known as chemical chaperones are major cellular compounds that favor, by an unclear mechanism, protein's compaction and stabilization of the native state. Here, we have examined the chaperone effect of the naturally occurring trimethylamine N-oxide (TMAO) osmolyte on a loosely packed protein (LPP), known to be a highly flexible form, using an apoprotein mutant of the flavin-dependent RNA methyltransferase as a model. Thermal and chemical denaturation experiments showed that TMAO stabilizes the structural integrity of the apoprotein dramatically.
