With the development of the Makler counting chamber, the reproducibility and accuracy of computer-assisted semen analysis and of manual determination of sperm concentration and sperm motility were significantly enhanced beyond what is possible with other methods, such as the hemocytometer, the Horwell chamber, the Petroff-Hausser chamber, and Chartpak slides. The use of Micro-Cell, a disposable...

BACKGROUND Factor H regulates the alternative pathway of complement. The protein has three heparin-binding sites, is synthesized primarily in the liver and copurifies from platelets with thrombospondin-1. Factor H mutations at the C-terminus are associated with atypical hemolytic uremic syndrome, a condition in which platelets are consumed. Objectives The aim of this study was to investigate if...

Ultrasonic technology is widely used to assist many industrial and domestic applications. However, the effect of ultrasonic washing on the thermophysiological properties of natural based fabrics has not been studied yet. This study aims to examine the relationship between unwashed, ultrasonically washed, and conventionally washed fabrics in terms of their abrasion behavior, flexural rigidity, a...
