Assessment of follicle viability using fluorescence microscopy before and after ovarian thawing.

The incidence of young women diagnosed with cancer has been globally increasing. In many cases the surgical approach followed by chemotherapy, radiotherapy or hormonal therapy could lead to infertility or premature ovarian failure. Several options are available in order to preserve fertility and increase the future gestation rate.

Obsessive compulsive symptoms are associated with better functioning independently of cognition in schizophrenia.

Objectives: Although the relationship of obsessive-compulsive symptoms (OCSs) with both cognition and social functioning (SF) has already been the focus of research in schizophrenia, the moderation of the relationship of OCSs with SF by cognition has not been explored to date. We investigated the association of OCSs with SF and its interaction with cognition in schizophrenia.

Methods: We recruited 110 schizophrenia patients and assessed OCSs (Yale-Brown Scale), schizophrenia symptoms (Positive and Negative Syndrome Scale), SF (Strauss-Carpenter Scale) and cognition.

Leptin levels in women with polycystic ovaries undergoing ovarian stimulation: relation to lipoprotein profiles.

Aim: To investigate serum and follicular fluid (FF) leptin levels in normally-ovulating women and subjects with polycystic ovary syndrome (PCOS) undergoing controlled ovarian stimulation and correlate them with their lipid lipoprotein profile.

Materials And Methods: We included 70 PCOS women (35 lean and 35 overweight or obese) and 76 age- and weight-matched non-PCOS controls (39 lean and 37 overweight or obese).

Results: Serum levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, apolipoprotein B, lipoprotein(a) and homocysteine in women with PCOS were significantly higher compared to control groups while levels of high-density lipoprotein (HDL) cholesterol and apolipoprotein A1 were significantly lower.

Prevalence of vasomotor, psychological, psychosomatic and sexual symptoms in perimenopausal and recently postmenopausal Greek women: association with demographic, life-style and hormonal factors.

Aim: To assess the prevalence of climacteric symptoms and their association with demographic, life-style and hormonal parameters in Greek peri- and recently postmenopausal women.

Methods: 1025 Greek women who were either perimenopausal or within their first 5 postmenopausal years participated in this cross-sectional observational study. Menopausal symptoms were assessed by the Greene Climacteric Scale and were tested for associations with demographic, anthropometric, life-style and hormonal parameters.

RGDS peptides immobilized on titanium alloy stimulate bone cell attachment, differentiation and confer resistance to apoptosis.

A major cause of implant failure in skeletal tissues is failure of osseointegration, often due to lack of adhesion of cells to the titanium (Ti) alloy interface. Since arginine-glycine-aspartic acid (RGD)-containing peptides have been shown to regulate osteoblast adhesion, we tested the hypothesis that, bound to a Ti surface, these peptides would promote osteoblasts differentiation, while at the same time inhibit apoptosis. RGDS and RGES (control) peptides were covalently linked to Ti discs using an APTS linker.

Apoptosis and survival of osteoblast-like cells are regulated by surface attachment.

We tested the hypothesis that RGDS peptides regulate osteoblast survival in culture. Osteoblast-like MC3T3-E1 cells were allowed to attach to RGDS peptides that had been tethered to a silicone surface utilizing a previously described grafting technique. The RGDS-modified surface caused up-regulation of alpha(v)beta(3) integrin.
