AIM This study aimed to compare the solubility of a universal restorative resin composite (Filtek Z250; FZ250) and a silorane-based resin composite (Filtek Silorane; FS) after immersion in alcohol-containing mouthrinse, alcohol-free mouthrinse, and artificial saliva. METHODS 30 discs (10 mm × 1 mm) were prepared from each material and desiccated until a constant mass was obtained. Specimens w...

BACKGROUND AND OBJECTIVES The study's objective was to determine whether participation in an international health rotation in a Spanish-speaking country (immersion) is associated with improved Spanish fluency compared to participation in domestic medical Spanish coursework alone. METHODS Participants matriculated at one US medical school in the years 2004--2008. At matriculation (baseline), a...

BACKGROUND Pre-cooling is known to enhance exercise performance in soccer players. However, little information currently exists regarding precooling effects in Iranian young soccer players. OBJECTIVES The aim of this study was to assess the effect of precooling (water immersion) on exhaustive performance in the heat ( temperature = 32 - 34°C, humidity = 50%). PATIENTS AND METHODS Sixteen yo...

The present study was carried out to investigate the analgesic activity of Etoricoxib (10 mg) for individual drug therapy and etoricoxib (5 mg) for combination therapy with diclofinac potassium (10 mg) using Acetic acid induce writhing, Hot plate and Tail immersion methods. The test and standard drugs significantly (p<0.001) reduced the number of abdominal constriction and stretching of hind li...

ore than thirty years of language immersion instruction in Canada and the United States have produced an impressive body of research demonstrating its benefits to students. This research indicates that students gain proficiency in a second language, develop cultural awareness, and perform as well as or better than their non-immersion peers on English proficiency tests (Rubio, 1998). As a result...

Phencyclidine (1-(1-phenylcyclohexyl) piperidine, PCP, I) and ketamine (2-O-chlorophenyl-2-methylaminocyclohexan, II) have shown analgesic effects. Some of its derivatives were synthesized and their biological properties have been studied. In this study, a new derivative of PCP, (1-[1-(3-methoxyphenyl) (tetralyl)] piperidine, PCP-OCH3-tetralyl, III) was synthesized and the acute thermal pain of...

Environment safety measurements have resulted in use of peroxide as bleaching chemical in place of chlorine and chlorine dioxide. Concentration and composition of chemicals affects corrosion aspects, the suitability of existing plant metallurgy and materials of construction of bleach plants. Accordingly long term immersion and electrochemical corrosion tests were conducted on stainless steel 30...

To evaluate the effectiveness of recovery strategies on physical performance during a 3-day tournament style basketball competition, 29 male players (mean age 19.1 years, s= 2.1; height 1.84 m, s= 0.34; body mass 88.5 kg, s= 14.7) were assigned to one of three treatment groups: carbohydrate+stretching (7.7 g kg(-1) day(-1), s= 1.7; 'n = 9), cold water immersion (11 degrees C, 5 x 1; n = 10) or ...
