Oxidative Stress in idiopathic Oligoathenoteratozoospermia (iOAT) and its Relation to Midpiece and Mitochondrial Anomalies.
INTRODUCTION AND AIM OF THE STUDY Idiopathic Oligoathenoteratozoospermia (iOAT syndrome) can be found in a high percentage of patients with male infertility. Reactive oxygen species (ROS) have been implicated in male infertility in the last years. In the present study we measured the levels of Reactive oxygen species (ROS) and Oxidative stress (OS) in iOAT patients and their correlation with ... Read more

Biochemical role of cytokines in vitiligo.
Vitiligo is a common skin disorder that is caused by selective destruction of melanocytes, resulting in disfiguring loss of pigment. There are convincing evidences that cytokines and T cell mediate immunity may have a role in its pathogenesis .The present study was conducted to evaluate the efficacy of narrow-band ultraviolet BUVB) therapy and to determine some of the immunological changes ...

Phenotypic characterization of inflammatory cellular infiltrate in lesional skin from patients with pityriasis rosea.
Background Pityriasis rosea (PR) is an acute, self-limiting papulosquamous skin disease. T-helper lymphocytes play an important role in the pathogenesis of PR. However, the role of cytotoxic T-lymphocytes is poorly understood. Objective To investigate the immune profile of mixed inflammatory cell infiltrate in skin lesions with PR. Methods The study included 10 biopsy specimens from lesional skin with clinical diagnosis ... Read more

Comparative study between the effect of calcipotriol and combination of calcipotriol and mometasone furoate on apoptosis in psoriatic patients.
OBJECTIVES: To compare the expression of Bcl-xl (antiapoptotic) and Bax (proapoptotic) factors in psoriatic patients treated with calcipotriol alone with those treated with combination of calcipotriol and mometasone furoate, also to compare the expression of these factors in keratinocytes of lesional with non lesional skin of psoriatic patients and of controls, and lastly to correlate the level of these parameters ...

Expression of nerve growth factor and its high-affinity receptor, tyrosine kinase A proteins, in the human scalp skin.
Background: Nerve growth factor (NGF) and its high-affinity recep- tor, tyrosine kinase A (TrkA), are members of the neurotrophin family. NGF–TrkA are involved in murine hair morphogenesis and cycling. To date, their expression in human hair follicle (HF) is unknown. In this investigation, we hypothesize that NGF–TrkA proteins are expressed in the human scalp skin. Moreover, NGF–TrkA expression in HF ... Read more

Epidemiological studies on pediculosis capitis in Sohag governorate.
This is an observational descriptive study conducted upon three primary school pupils in Sohag Governorate. The idea was to estimate the incidence and the epidemiological factors related to Pediculosis capitis infestation amongst the selected population. It has been found that the infestation affected about 16 % of the whole group. Rural pupils were more frequently, albeit insignificantly, infested (17.44 versus ... Read more

Sexual dysfunction in chronic hepatitis patients
Introduction: Data about sexual dysfunction (SD), particularly erectile dysfunction (ED), in patients with chronic hepatitis B and C remain unclear and insufficient. Aim: To determine sexual problems particularly (ED) in patients with chronic hepatitis B and C, study changes in sex hormones and liver functions in chronic hepatitis patients with and without sexual problems and correlate sexual problems with other ...
