The prostaglandins (PGs) synthesized from C14-arachidonic acid by the homogenized sheep ureter were identified as being prostacyclin (PGI2), PGF2 alpha and thromboxane B2 (TXB2). The radioimmunoassay (RIA) estimation of 6-keto-PGF1 alpha, a stable metabolite of PGI2, confirms that it was the major metabolite of arachidonic acid. Aqueous extracts of fresh(More)
1. Homogenates of garlic (Allium sativum), onions (Allium cepa) and Allium porum were in vitro incubated with [14C]arachidonic acid. 2. Separation of labelled prostaglandins and thromboxanes were accomplished by thin-layer chromatography (TLC) and the Rf values were compared with those of authentic standards. 3. The prostaglandins identified were(More)
Objective: Nerve blockade is commonly used in oncosurgical procedures as an alternative to general anesthesia for older patients and those with significant medical problems. We report a single tertiary oncology center experience in performing various lip resections and reconstructive techniques using this technique. Patients and methods: sixty patients with(More)

Intranasal antibiotics as an adjunct to corticosteroids usually demonstrate the greatest symptom relief. AIM We wanted to clinically evaluate the effects of a topical antibiotic and steroid combination administered intranasally,(More)
This paper presents an overview of adaptive techniques used for distance protection in power systems. The concept of distance protection is elaborated to bring a clear picture of the relay operation principles. The problems faced by conventional distance relays are summarized in order to reveal their limitations under certain conditions. Finally, recent(More)

Virtual reality has been involved in a wide range of academic and commercial applications. It can give users a natural feeling of the environment by creating realistic virtual worlds. Since its first release in 1994, the VRML (Virtual Reality Modeling Language) is widely used today for simulations, scientific visualizations and different architectural(More)
