Seasonal trend in the occurrence of myelomeningocele in nigeria: a hypothesis of climate-induced oxidative stress.

Purpose: Myelomeningocele is the most severe birth defect compatible with long-term survival. It accounts for 5.7% of neurological surgeries in Nigeria.

A Multicenter Retrospective Cohort Study of the Profile of Seminal Fluid Analyses of Men Seeking Fertility Care at Different Hospitals.

Background: Male infertility contributes 40 % of couple infertility. The prevalence of abnormal semen parameters has been on the increase. Age among other factors affects the fertility potential of males.

Peri-operative blood transfusion in open suprapubic transvesical prostatectomy: relationship with prostate volume and serum total prostate specific aantigen (TPSA).

Introduction: Open simple prostatectomy is the most effective and the most durable method of controlling symptoms associated with benign prostatic hyperplasia, especially in sub- Saharan Africa, where TURP set and expertise are unavailable in most health institutions. The risk of perioperative heterologous blood transfusion in open transvesical prostatectomy varies widely from one centre to another, and this risk is documented to improve over time in any given centre.

Aim: To determine the perioperative blood transfusion rate in our centre and to determine its relationship with the prostate volume estimated with transabdominal ultrasonography and serum total PSA.

Search for charged Higgs bosons in ee collisions at [Formula: see text].

A search is made for charged Higgs bosons predicted by Two-Higgs-Doublet extensions of the Standard Model (2HDM) using electron-positron collision data collected by the OPAL experiment at [Formula: see text], corresponding to an integrated luminosity of approximately 600 pb. Charged Higgs bosons are assumed to be pair-produced and to decay into [Formula: see text], or AW. No signal is observed.
