There have been some proposals that stem cells exist in the ovarian surface epithelium (OSE) of the adult human ovary; however, no direct evidence of such cells has been given until now. The aim of this study was to isolate the putative ovarian stem cells (OSCs) from the OSE layer in women with no naturally present oocytes and follicles--20 postmenopausal(More)
Tissue repair begins with clot formation and platelet degranulation, which release the growth factors (GFs) necessary for wound repair. Platelet-derived GFs are biologically active substances that enhance tissue repair mechanisms such as chemotaxis, cell proliferation, angiogenesis, extracellular matrix deposition, and remodeling. This review describes the(More)
In this review, we describe the platelet surface molecules with special focus on the polymorphic glycoproteins giving rise to the human platelet alloantigen (HPA) system. We list the platelet glycoprotein complexes GPIa/IIa, GPIIb/IIIa, GPIb/V/IX and some other molecules, the corresponding genes that encode them and we describe their polymorphisms as well(More)
Sulfation of drugs depends on the availability of 3'-phosphoadenosine 5'-phosphosulfate (PAPS), which requires inorganic sulfate for its synthesis. Therefore, decreased alimentary intake of inorganic sulfate or its precursor, cysteine, may compromise sulfation of xenobiotics. To test this hypothesis, separate groups of rats were maintained for 5 days on(More)
INTRODUCTION Heparin-induced thrombocytopenia (HIT) is an immune-mediated thrombocytopenia associated with heparin therapy. The diagnosis consists of a combination of pretest probability and laboratory testing. The routinely available laboratory antigen binding assays for the detection of specific antibodies have a low HIT-positive predictive value;(More)
BACKGROUND/AIMS A 50-year-old type 2 diabetic male with a comminuted fracture of the tibia and delayed union after insufficient initial osteosynthesis with a resulting pseudoarthrosis was treated operatively by using a graft composed of platelet gel mixed with autologous cancellous bone. The essential idea of this therapy was to combine the healing(More)
Typing of human platelet alloantigens (HPA) is necessary in various clinical situations. The purpose of this study was to type a random sample of the Slovenian population for HPA alleles, in order to obtain genetic population data. A total of 152 unrelated Slovenian blood donors were genotyped for HPA-1, -2, -3, -4 and -5 alleles using a simple method that(More)
Little is known about parthenogenesis in the human ovary. What is known is related to patients with teratoma in their medical history. Ovarian surface epithelium (OSE) was often proposed as a source of ovarian stem cells with an embryonic character in the past, and was also termed "germinal epithelium." The aim of this study was to isolate putative stem(More)
BACKGROUND Slow graft healing in bone tunnels and a slow graft ligamentization process after anterior cruciate ligament (ACL) reconstruction are some of the reasons for prolonged rehabilitation. AIMS The purpose of this study was to determine if the use of platelet gel (PG) accelerates early graft revascularization after ACL reconstruction. METHODS PG(More)
The effect of feeding 0.1% hexachlorobenzene (HCB) for 55 days on mortality, body weight, urinary porphyrin excretion, serum thyroid hormones and induction of liver microsomal enzymes was studied in female Sprague-Dawley rats. This dosage regimen, followed by 42 days of a regular diet, resulted in 33% mortality with a mean time to death of 67 +/- 4 days.(More)
