The goals of this study were to isolate and characterize the nonlipid matrix of human cholesterol gallstones. The lipid portion of gallstones was dissolved in ethanol/ether, leaving an insoluble, granular, brown-black matrix that constituted 12.5% of solitary large stones and 3.5% of multiple small stones. The matrix was partially solubilized by sonication and studied by exclusion gel chromatog...

BACKGROUND The aim of our study has to evaluate the antiproliferative effect of polyphenols and sterols extracted from the virgin argan oil on three human prostatic cell lines (DU145, LNCaP, and PC3). METHODS Cytotoxicity, anti-proliferative effects and nuclear morphological changes of cells were analyzed after treatment with sterols and polyphenols. The results were compared to 2-methoxyestr...

The incidence of Brucella canis infection in humans is unknown in Turkey. In this study, we investigated the prevalence of B. canis infection in human sera obtained from six regions in Turkey and comparatively evaluated the results obtained by agglutination-based techniques using standardized antigens made from B. canis. The patients (n = 1,746) presented with clinical symptoms that were si...

Recent studies have indicated an important role of ATP receptors in spinal microglia, such as P2Y12 or P2Y13, in the development of chronic pain. However, intracellular signaling cascade of these receptors have not been clearly elucidated. We found that intrathecal injection of 2-(methylthio)adenosine 5'-diphosphate (2Me-SADP) induced mechanical hypersensitivity and p38 mitogen-activated protei...

Background Failure of Male Pronucleus (MPN) formation is a major concern in the success of Intracytoplasmic Sperm Injection (ICSI) in some species. Despite the conducted unsuccessful efforts to improve ICSI efficiency in ovine, the present study was aimed to improve MPN formation and embryo development in ovine ICSI procedure through accompaniment of sperm pretreatment with co-injection of some...

A passive hemagglutination (PHA) test for measles was evaluated in comparison with hemagglutination inhibition (HI) and neutralization (NT) tests. The PHA test determines exclusively the level of antibody directed to the hemagglutinin protein of measles virus. The ratio of PHA to HI titer was 1 to 32 (geometric mean, 6.5) for the first 5 weeks of infection but declined to near unity thereafter....
