Chronic Opium Treatment Can Differentially Induce Brain and Liver Cells Apoptosis in Diabetic and Non-diabetic Male and Female Rats.

It has been shown that some opium derivatives promote cell death via apoptosis. This study was designed to examine the influence of opium addiction on brain and liver cells apoptosis in male and female diabetic and non-diabetic Wistar rats. This experimental study was performed on normal, opium-addicted, diabetic and diabetic opium-addicted male and female rats.

An in vitro study of the effect of spreader penetration depth on apical microleakage.

The purpose of this study was to evaluate the effect of spreader penetration depth on apical microleakage using the lateral compaction method. A total of 96 extracted maxillary central incisors were instrumented using the step-back method, and randomly divided into the following four experimental groups: A) with tug-back and spreader penetration 1 mm short of the working length; B) without tug-back and spreader penetration 1 mm short of the working length; C) without tug-back and spreader penetration to the working length; D) with tug-back and spreader penetration to the working length. Microleakage evaluation was conducted using the dye penetration method, and ANOVA test was used for statistical analysis.

Survey of changes in complete blood count and red cell indices of whole blood incubated in vitro at different temperatures up to 48 hours.

Background: Complete blood count (CBC) is one of the most common and conventional blood test that physicians usually request. However the results of this test are affected by different factors such as, the temperature and duration of incubation, therefore the aim of this survey was to evaluate the effect of temperature and time of incubation on CBC, red blood cells (RBC) indices and white blood cells (WBC) differential count.

Methods: In a cross-sectional study, blood samples were taken from 30 healthy medical students of Rafsanjan University (15 males and 15 females).
