Marginal accuracy of interim restorations fabricated from four interim autopolymerizing resins.

Statement Of Problem: One of the most important requirements for interim restorations is good marginal adaptation. Polymerization shrinkage of interim restorative materials can jeopardize the marginal integrity of interim restorations.

Purpose: The purpose of this study was to compare the marginal accuracy of interim restorations made with 4 interim materials.

Treadmill running reverses retention deficit induced by morphine.

Human and animal studies have suggested that exercise has benefits overall health and cognitive function. The aim of this study was to investigate the effect of treadmill running on passive avoidance learning and memory deficit in morphine-treated rats. The passive avoidance learning was measured in different time intervals (1, 2 and 24 h as well as 1 week and 1 month).

In vitro evaluation of antifungal effects of mineral trioxide aggregate and portland cement on Candida albicans.

Introduction: Candida Albicans (CA) is by far the most common yeast of oral infections, including endodontic infections. The aim of this study was to evaluate and compare the antifungal effect of white-colored mineral trioxide aggregate (WMTA) and Portland Cement (PC) using a tube-dilution test.

Materials And Methods: WMTA and PC were tested freshly mixed and after 24 h.

Ultrasound as an alternative to aspiration for determining the nature of pleural effusion, especially in older people.

Sonography was performed by two expert radiologists separately after selecting 80 patients (45 men and 35 women) whose pleural fluids had been aspirated and examined by the lab. The radiologists were given no clinical information concerning the patients, and the result compared with lab results. The radiologists evaluated three criteria in determining the nature of the pleural effusion: septation, echogenicity, and thickening of pleura by more than 3 mm.

Effect of exercise on learning, memory and levels of epinephrine in rats' hippocampus.

The aim of the present study was to investigate effect of exercise on learning and memory, long-term potentiation and levels of epinephrine in the rat hippocampus. Treadmill trained (one hour at 17 m·min(-1) for 10 days) and corresponding control rats went through spatial learning process on a Morris water maze for 8 days. The time to reach the platform (latency), the length of swim path, and the swim speed were used for the evaluation of spatial learning.

Training families to better manage schizophrenics' behaviour.

The influential role of family in the outcome of chronic schizophrenia is well documented. Because families have become the primary caretakers, this study was designed to train parents of chronic schizophrenics to better manage their offspring. The sample comprised 40 parents whose offspring were admitted to a psychiatric ward from April to June 1996.

Incidence of and risk factors for proliferative retinopathy and its association with blindness among diabetes clinic attenders.

Background: Proliferative diabetic retinopathy (PDR), a prevalent late-stage complication of diabetes, is associated with severe visual loss. The objectives of this report were to estimate the incidence of and risk factors for PDR using routinely collected data from a clinical information system at University Hospital Nottingham for insulin- and non-insulin-dependent (insulin-treated and non-insulin-treated) diabetes separately. We also attempted to assess the risk of blindness in these diabetes clinic attenders.

Pulsus alternans during general anesthesia with halothane: effects of permissive hypercapnia.

Background: Pulsus alternans is a classic type of abnormal pulse. It can be defined as a regular alternation of pulse amplitude in which runs of weak and strong beats follow each other alternatively without any change in cycle length. It may be a sign of severe decompensated congestive heart failure.
