The amounts of protein measured by absorbance at 280 nm, succinyl-L-alanyl-L-alanyl-L-prolyl-L-leucine-p-nitroanilide (Suc-Ala-Ala-Pro-Leu-pNA), D-valyl-cyclohexyl-alanyl-L-arginine-p-nitroanilide (ValCHA-Arg-pNA), and glutamyl-L-phenylalanine-p-nitroanilide (Glu-Phe-pNA) amidolytic activities,...
The aim of the study was to investigate the role of zinc therapy in 125 male cigarette smokers with infertility. The mechanism involved in the zinc/cadmium relationship was evaluated through the effect of a zinc-deficient diet and supplementation on testes of male adult Sprague-Drew rats. Heavy...
This study was performed to understand the regional distribution of superoxide anion radicals and hydrogen peroxide within the spermatozoa of mice during both normal and altered situations of epididymal maturation. The intracellular O2- levels were probed employing dichlorodihydrofluorescein...
A study of fertility was conducted in postpubertal male patients who had been treated for acute lymphoblastic leukemia (ALL) during childhood or adolescence between 1970 and 1980. Thirteen men (age 18 to 35 years) participated on a volunteer basis. Their age at diagnosis was between 2 and 15...
Since increased levels of soluble CD23 (sCD23) were demonstrated in patients with autoimmune diseases, seminal plasma sCD23 levels were examined in 110 men divided into seven groups according to etiological diagnosis of infertility and two groups on the basis of normal or abnormal spermiogram....
There has been some controversy about whether males undergo an andropause (male equivalent of a menopause). This study seeks to describe how older males perceive and understand this entity and whether there is an association between the age of onset of andropause and risk factors such as ethnic...
Semen assessments were performed on ejaculates from 25 men with proven fertility requesting vasectomy. Multiple cytological slides were made simultaneously from each ejaculate and analyzed by a single technician. The morphology data obtained were analyzed for repeatability. The mean +/- SD for...
The present study was conducted to examine the presence of insulin-like growth factor-1 receptor (IGF1R) in human sperm cell. The IGF-1R monoclonal antibody (MAb) specifically immunoprecipitated two protein bands of 135 and 220 kD, respectively, from the reduced human sperm extract. These bands...
