Correlation between Sperm Quality Parameters and Seminal Plasma Antioxidants Status
Background: There is growing evidence that damage to spermatozoa by reactive oxygen species (ROS) play a key role in male infertility. Objective: The aim of the present study was to assess the antioxidant status of seminal plasma by measuring total antioxidant capacity (TAC) and activities of catalase and superoxide dismutase (SOD) in men with asthenozoospermia, asthenoteratozoospermia and olig...

متن کاملLocally Efficient Estimation of Regression Parameters Using Current Status Data
In biostatistics applications interest often focuses on the estimation of the distribution of a time-variable T . If one only observes whether or not T exceeds an observed monitoring time C, then the data structure is called current status data, also known as interval censored data, case I. We consider this data structure extended to allow the presence of both time-independent covariates and ti...
متن کاملChromatin status in human ejaculated spermatozoa from infertile patients and relationship to seminal parameters.
The aim of this study was to evaluate the chromatin status in different groups of patients. Five groups of men were selected: pre-vasectomy; male factor infertility; varicocele; immunological male infertility; and idiopathic infertility. Chromatin status was evaluated using flow cytometry after staining the DNA with the fluorochrome propidium iodide. Differences were observed in the state of sp...
متن کاملCmb Anisotropies, Cosmological Parameters and Fundamental Physics: Current Status & Perspectives
I describe briefly the Cosmic Microwave Background (hereafter CMB) physics which explains why high accuracy observations of its spatial structure are a unique observational tool both for the determination of the global cosmological parameters and to constrain observationally the physics of the early universe. I also briefly survey the many experiments which have measured the anisotropies of the...
