The present study was undertaken to evaluate a nested polymerase chain reaction (PCR) for detection of Y chromosome-specific fetal DNA in maternal plasma and urine of pregnant women during different gestational stages. DNA isolated from plasma and urine samples of 80 pregnant women (between 7 and 40 weeks' gestation) underwent amplification for Y(More)
Wall teichoic acid (WTA) comprises a class of glycopolymers covalently attached to the peptidoglycan of gram positive bacteria. In Listeria monocytogenes, mutations that prevent addition of certain WTA decorating sugars are attenuating. However, the steps required for decoration and the pathogenic process interrupted are not well described. We(More)
The expression of delta isoforms of calcium-calmodulin/dependent protein kinase II (CaMKII) has been reported in mammalian skeletal muscle; however, their functions in this tissue are largely unknown. This study was conducted to determine if deltaCaMKII expression was altered during regeneration of skeletal muscle fibers in two distinct models. In the first(More)
OBJECTIVE The aim of this study was to determine whether or not a noninvasive procedure utilizing maternal peripheral blood as the source of DNA and polymerase chain reaction (PCR) could be used to detect fetal rhesus D (RhD) status as well as fetal gender during different gestational stages of pregnancy. MATERIALS AND METHODS Maternal blood samples were(More)
Time of flight diffraction (TOFD) technique is a well-developed ultrasonic non-destructive testing (NDT) method and has been applied successfully for accurate sizing of defects in metallic materials. This technique was developed in early 1970s as a means for accurate sizing and positioning of cracks in nuclear components became very popular in the late(More)
We studied the effect an inhibitor of Ras-GTPase (FPTIII, 1.5 mg/kg alt diem for 4 weeks) on mean arterial pressure (MAP), urine protein, vascular reactivity and cardiac function in streptozotocin (STZ)-induced diabetes in control normotensive (WKY) and spontaneously hypertensive rats (SHR). The increased urinary protein in STZ-treated WKY (D-WKY) and(More)
Non Destructive testing of structural materials is an important activity in many industries. Ultrasonic NDT is one such method widely used in this field. Pulse Echo and Through Transmission are conventional testing techniques which use reflected and transmitted sound energy respectively. But these techniques are highly dependent on defect orientation. Time(More)
Chronic surgical denervation of the rat vas deferens leads to an enhanced contractile response of the tissue to norepinephrine in vitro. Norepinephrine produces a higher rate of protein kinase C translocation to the particulate fraction of denervated tissues as compared with the paired, control vas deferens. Diacylglycerol generation in response to(More)
OBJECTIVE The signalling mechanisms involved in regulating altered vascular reactivity in diabetes are not fully understood. The aim of this study was to investigate the role of Ras-GTPase in the development of abnormal vascular reactivity in diabetes. MATERIALS AND METHODS We investigated the ability of chronic administration of FPTIII (1.5 mg/kg), an(More)
The Wnt/β-catenin signaling pathway is a key regulator of embryonic development that was first identified in drosophila. More recent work has suggested a role for this pathway in mammalian, myogenesis but this process remains to be more completely elucidated. The current study was designed to investigate the role of the Wnt3a/β-catenin signaling module in(More)
