Background Male infertility management has made significant progress during the past three decades, especially after the introduction of intracytoplasmic sperm injection (ICSI) in 1992. However, many boys and men still suffer from primary testicular failure due to acquired or genetic causes. New and novel treatments are needed to address these issues. Spermatogenesis originates from spermatogon...

A study was conducted to investigate the effect of follicular size (small,

Tissue Sealants In article number 2100803 by Boaz Mizrahi and co-workers, an elastic biodegradable sealant is designed mixing two complementary neat (solvent-free) star shape prepolymers. This mixture, which hardens in several seconds, offers advantages over existing tissue sealants, including excellent mechanical properties degradation behavior, minimal cytotoxicity vitro biocompatibility vivo.

introduction: in orthodontic therapy ,different materials are used and their presence in oral cavity may modify their properties. the purpose of this study was to evaluate the direct and indirect biocompatibility of three orthodontic composite resins on culture of human oral fibroblasts. methods: this was an interventional experimental study. the biocompatibility of three orthodontic composite ...

Background: In the last few years, a marked decrease in male fertility has been reported. Environmental factors were recently suspected for this problem. The misuse of medicines especially antibiotics are among environmental factors that can affect reproductive system. Ciprofloxacin is a synthetic antibacterial agent belonging to the family of fluoroquinolones with a very broad spectrum effect ...

An increasing interest in bio-hybrid systems and cell-material interactions is evident in the last years. This leads towards the development of new nano-structured devices and the assessment of their biocompatibility. In the present study, the development of free-standing single layer poly(lactic acid) (PLA) ultra-thin films is described, together with the analysis of topography and roughness p...

Patients treated with peritoneal dialysis (PD) are at risk for development of ultrafiltration failure and peritonitis. The relative unphysiologic composition of the currently used peritoneal dialysis fluids (PDF) is a major cause for the development of morphologic changes of the peritoneal membrane such as fibrosis and new vessel formation, ultimately resulting in ultrafiltration failure. In re...

Magnesium (Mg) and its alloys have attracted considerable attention owing to their excellent biodegradable properties biocompatibility. Novel Mg–Sn–Ge ternary Mg were developed as potential materials for orthopedic applications because of alloying elements naturally present in humans. The feasibility these was investigated terms mechanical properties, degradation, cytocompatibility, hemocompati...
