    Sammanfattning : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. LÄS MER

    Sammanfattning : A balanced tear film is essential for a healthy ocular surface. Insufficient tear production may result in dry eye, a common disorder in the elderly population. Dry eye causes significant discomfort in the patients and may lead to visual impairment and ocular infections. LÄS MER

    Sammanfattning : In this study, the biosynthesis of proteoglycans (PGs) was examined in articular cartilage of canine hip joint after long-distance running experiment and in bovine chondrocyte cultures during in vitro loading with hydrostatic pressure. In addition, new assays were developed for more sensitive quantitation of glycosaminoglycans (GAGs) and PGs. LÄS MER
