Rap1, is required to define the position of the new bud. 1997). In vitro, this interaction is not sufficient to stimulate the GEF activity of Cdc24p, and one functional out-and Molecular Biology University College London come of this interaction in vivo, therefore, is likely to be the localization of Cdc24p to the presumptive bud site London WC1E 6BT United Kingdom (Zheng et al., 1995). In S. p...
The vascular permeability of the endothelium is finely controlled by endothelial (VE)-cadherin-mediated cell–cell junctions. In majority normal adult tissues, cells in blood vessels maintain at a relatively low level, while response to inflammation, they limit barrier function induce plasma leakage and extravasation immune as defense mechanism. Thus, dynamic but also simultaneously tight regula...
renal artery stenosis (ras) is the most common cause of secondary hypertension. preliminary data indicate that aspirin renography with hippurate may be more sensitive for detection ras. in this study 20 patients with known or suspected ras underwent aspirin renography (20 mg/kg orally 1 hour before injection of radiotracer) and captopril renography (50 mg orally) with 99mtc-dtpa. renal angiogra...
Background: Recurrent aphthous stomatitis (RAS) is among the most common oral lesions and pain is often the chief complaint of patients. The main etiology of RAS is unknown but several predisposing factors have been suggested. This study aims to assess the correlation of blood types (ABO/Rh) with RAS. Methods: We conducted this prospective screening study on 50 patients with RAS and 50 controls...
The Gram-negative bacterium Myxococcus xanthus glides on solid surfaces and periodically reverses the direction of movement. Work published in this issue of The EMBO Journal (Leonardy et al, 2010) reports on the small GTPase MglA that ensures the correct polarity of the motility engines through its GTP/GDP cycle in conjunction with its cognate GAP, MglB. MglA has also been shown to interact wit...

In this study 20 patients with known or suspected RAS underwent aspirin renography (20 mg/kg orally 1 hour before injection of radiotracer) and captopril renography (50 mg orally) with 99mTc-DTPA. Renal an...
Background and purpose: Recurrent aphthous stomatitis (RAS) or oral aphthous are among the most common problems in adults. Stressful events could cause these ulcers. The purpose of this study was to determine the prevalence of recurrent aphthous stomatitis among students in Mazandaran University of Medical Sciences and its relationship with anxiety. Materials and methods: In this analytical cr...
Background and Aims: The purpose of the present study was to review the studies regarding serological and salivary oxidant / antioxidant status in patients with recurrent aphthous stomatitis (RAS). Materials and Methods: The literature was searched using key words RAS, Antioxidants, Saliva, Hematinic (s) and Hematinic Acid in the last 10 years, particularly the recent 3 years (2010-2013). A...
