The effect of thrombin was tested in vitro on rings of bovine retinal small arteries (internal diameter approximately 200 microns). Cumulative addition of thrombin (0.001-10 units/ml) induced a variable concentration-dependent contraction of the retinal arteries. The contractions were slow in onset and reached a plateau after 5-8 minutes when thrombin was added cumulatively to the organ bath. T...

One of the most important steps is accurate impression making for fabrication of fixed partial denture. The two different putty-wash techniques that are commonly used are: (1) Putty-wash one-step technique, (2) putty-wash two-step technique. A uniform wash space is needed for an accurate impression. Nissan et al recommended the use of two-step technique for accurate impression making as there i...

We describe a comparison of the scrub-wash method of Williamson and Kligman and a swab-wash method for the enumeration of cutaneous microflora. The swab-wash method provides a less traumatic alternative to the scrub-wash method and can be used to sample the cutaneous microflora of premature neonates.

This article describes the clinical procedures for a modified putty-wash impression technique. In this method, the hydraulic pressure induced from planned flowing the wash material from the inner surface of putty impression toward the vestibules pull over the gingival tissues covering the finishing line. This simple method reduces the need to using retraction cord in normal depth finishing line...

BACKGROUND The indwelling urinary catheter is an essential part of modern medical care. Unfortunately, when poorly managed, the indwelling catheter may present a hazard to the very patients it is designed to protect. Catheter-associated urinary tract infection (CAUTI) is the most common nosocomial infection in hospitals and nursing homes. AIMS AND OBJECTIVES The primary objective was to study...

Previous research has yielded conflicting results regarding the onset of semantic processing during morphological priming. The present study was designed to further explore the time-course of morphological processing using event-related potentials (ERPs). We conducted a primed lexical decision study comparing a morphological (LAVAGE - laver [washing - wash]), a semantic (LINGE - laver [laundry ...

BACKGROUND Trachoma is the world's leading cause of infectious blindness. The World Health Organization (WHO) has endorsed the SAFE strategy in order to eliminate blindness due to trachoma by 2020 through "surgery," "antibiotics," "facial cleanliness," and "environmental improvement." While the S and A components have been widely implemented, evidence and specific targets are lacking for the F ...

background: car wash waste water contains several contaminants such as organic matter, oil, grease, detergents and phosphates, all of which are harmful for the environment. in this study, the application of electrocoagulation (ec) to treat car wash waste water has been studied, and the operating parameters optimized. the electro-fenton (ef) for further contaminant removal was also investigated....
