PURPOSE To compare sperm parameters and intracytoplasmic sperm injection (ICSI) outcomes for testicular spermatozoa frozen on the day of the biopsy (DO) with those frozen after 24 h of in vitro culture (D1). METHODS In this retrospective study, from 1999 to 2012, forty-nine azoospermic patients were included to compare sperm (motility and viability) and outcomes (fertilization (FR), implantat...

ZAP-70 methylation 223 nucleotides downstream of transcription start (CpG+223) predicts outcome in chronic lymphocytic leukemia (CLL), but its impact relative to CD38 and ZAP-70 expression or immunoglobulin heavy chain variable region (IGHV) status is uncertain. Additionally, standardizing ZAP-70 expression analysis has been unsuccessful. CpG+223 methylation was quantitatively determined in 295...

Active migration of Entamoeba histolytica trophozoites through extracellular matrixes might play a role in host tissue destruction. Trophozoites degrade soluble fibronectin (FN) bound to their surface and adhere to substrate-bound FN, producing local degradation. FN proteolytic fragments were used to determine the nature of adhesion and motility-promoting domains within the protein. The 70-kDa ...

We carried out this study to assess the quality of semen regarding seasonal and geographical variability Murrah buffalo breeding bull in Nepal. aimed access seme n murrah considering help standardize producing protocol concern. A total eight bulls were used. Semen collection was done at once week two ejaculations considered an interval 30 minutes during Summer (June August), Autumn (September N...

AIM To ascertain whether caecal pH is different in patients with irritable bowel syndrome (IBS), whose primary symptoms are bloating and distension, to healthy controls. METHODS Motility and pH data were reviewed from 16 patients with Rome III defined IBS and 16 healthy controls, who had undergone a wireless motility capsule (WMC) study using a standardized protocol. Motility measures were an...

OBJECTIVES Reactive oxygen species (ROS) induced lipid peroxidation is associated with sperm function. Malondialdehyde (MDA) concentration and glutathione peroxidase (GPx) activity represent the lipid peroxidation and spermicidal antioxidant, respectively. We aimed to evaluate the relationship of MDA and GPx levels with sperm parameters. PATIENTS AND METHODS Specimens were divided into two gr...

This study was aimed at evaluating the in vitro effects of particulate matter (ranging from 2.5-10 m in an aerodynamic diameter, PM10) from an urban area on the motility of human spermatozoa. Samples of swim up selected human spermatozoa from three healthy men with normal semen parameters, according to WHO guidelines, were incubated for 4 hours with 10, 50 and 75 μg/ml of PM10. Kinetic paramete...

Varicocele is one of the most common causes of male infertility and spontaneous pregnancy rate after varicocelectomy is only about 30%. The most important seminal antioxidant is vitamin C but recent studies about the effects of vitamin C on spermatogenesis are controversial; therefore, we decided to evaluate its role after varicocelectomy. In a double blind randomized controlled clinical trial,...

We studied transcutaneous pCO2 monitoring in 70 neonates, most of them premature with respiratory distress syndrome. Measurements were at 44 degrees C. Calibration drift was large in some instances. Least squares linear regression analyses of transcutaneous pCO2 (y) vs arterial pCO2 (x) in kilopascals showed, for all observations (n = 516), for one observation randomly selected from each patien...

The role and expression of ROCKI and ROCKII in human breast cancer was investigated and the effect on clinical outcome assessed. ROCK knockdown cells (MDA-MB-231DeltaROCKI and MDA-MB-231DeltaROCKII were tested for their in vitro invasiveness, motility and in vivo tumour growth. Samples of fresh frozen breast tumour tissue (n=113) and normal background tissue (n=30) were processed for immunohist...
