Effect of Ochratoxin-A on Mouse Embryos
...Show More Authors

This study sought to determine malformation caused by Ochratoxin-A (OTA) on mouse embryos. Twenty adult female white Swiss mice (mus msculus) were divided into four groups, with five females per group, and with one male placed with two females in a cage. Avaginal plug was observed in the early morning and the day of mating was considered as day of pregnancy followed by the first day of pregnancy. Three sub lethal concentrations of OTA were applied to the respective groups (other than the control), 1mg/kg, 2mg/kg and 4mg/kg. The animals were given 0.1 ml per 10 gm body weight per concentration of OTA once a day during days 7-14 of pregnancy. The control group animals were given distilled water. The pregnant mice were dissected, and the embryos were extracted in order to identify the effects of the OTA. Number of parameters were studied including, difference in body weight of the mice before mating and after the end of the experiment, the weights and lengths of embryo, as well as a study of embryo malformation. The study shows no significant differences in the mean body weight of the pregnant mice in the 1 mg/kg group, compared to control group. A significant (P<0.01) decrease in the body weight of the treated mice was observed in the 2mg/kg and the 4mg/kg groups. As for the weight of the embryos, there was a significant (P<0.01) decrease in the body weight of the embryos in the mothers treated with OTA in the 1 mg/kg and 2 mg/kg treatment groups. The embryos of the 4mg/kg group of pregnant mice could not be recorded since they had been resorbed into their mothers uteri. Similarly, the results of the study showed a significant difference in the mean length of the embryos bodies in the 1mg/kg and 2mg/kg groups, compared with the non-treated control group. Many malformations induced in the embryos in those groups where it was possible to examine the embryos 1mg/kg and 2mg/kg compared to control mouse embryos, included loss of tail, lack of eyes, cleft lip and exencephaly, as well as spina bifida, curvature of the trunk and there were also reduction defects of the limbs. The study concluded that OTA have teratogenic effects on mice embryos

Motivations of Volunteers in Jordan: An Exploratory Study Based on a Sample of University Students within the Context of their Social Relations
...Show More Authors

Volunteerism is an element included in many human cultures. It represents a positive cooperative act between individuals and groups. It expresses the social value systems. As a social phenomenon, it develops in societies according to innumerous circumstances and conditions. This study uses a functional approach that assumes that volunteering performs six functions for volunteers. Namely, we assume that volunteering (1) creates a sense of protection (2) meets significant cultural values (3) improves professional status of volunteers, (4) strengthens their social relationships, (5) helps them achieve a better understanding of life, and finally, (6) enhances their outlook and self-esteem. The central aim of the study is to discuss these fun

Effect of early laparoscopic Cholecystectomy in Acute Cholecystitis
...Show More Authors

Background: Laparoscopic cholecystectomy (LC) has become the treatment of choice for elective cholecystectomy.Objectives: To evaluate the safety and feasibility of early LC for AC and to compare the results with delayed LC.Methods: A prospective study done from April 2011 to October 2013, 88 patients with diagnosis of AC were divided randomly into two groups according to the mode of treatment; (early group n=40) treated by early LC within first 72 hours or (delayed group, n=48) initial conservative treatment for 4-6 weeks, followed by delayed LC.Results: There was no difference between the two groups (early & delayed LC), operating time (early 80min, delayed70min), conversion rate (early 7.5%, delayed 6.25%),postoperative complicatio

Optimum Height of Plate Stiffener under Pressure Effect
...Show More Authors

The economical design of plate loaded by pressure can be obtained by using stiffeners instead of increasing the thickness of plate. The main subject of this work is to obtain the effect of stiffener height on the maximum stress in the plate subjected to pressure load. Different plate-stiffener sets are selected to find the effects of stiffener thickness, plate dimensions and pressure, on the optimum stiffener height. The models under consideration are square plates clamped rigidly from four edges. Finite Element method is used to analyze 160 different models by using the Finite Element software package ANSYS version 11. Another analysis method based on maximum stress equation is used to analyze 30 models. The graphical comparison of results
