TERATOGENIC EFFECT OF METHOTREXATE ON HISTOGENESIS OF TESTIS IN NEWBORN RAT
...Show More Authors

Background: Methotrexate (MTX) was one of the first drugs synthesized for a specific chemotherapeutic purpose used to inhibit folic acid (FA) for the treatment of acute lymphoblastic leukemia in children. Its history is closely related to the discovery and characterization of folic acid. It is used clinically in medicine to treat a range of cancerous and noncancerous conditions. MTX is currently used in gynecology to treat disorders arising from trophoblastic tissue, namely, ectopic pregnancy. MTX, the most frequently used diseasemodifying anti-rheumatic drug (DMARD), suppresses disease activity and reduces joint damage. The aim of study: It is designed to demonstrate the effect of MTX (7.5 mg/wk.) on the histogenesis of gonad (testis) of newborn Albino rat. Material & Methods: Twenty pregnant female rats taken, classified equally to 10 control and 10 treated with MTX intramuscularly (first dose at day 15 of gestation and second dose at two day after birth). After normal vaginal delivery, newborns harvested at day seven. For histological study the newborn gonad (testis) were fixed in Bouin’s fixative, paraffin infiltration, and then embedded sections stained with haematoxylin and eosin, the specimens independently read. The result: The histological investigation showing atrophy of seminiferous tubules, increase interstitial space with reduce interstitial connective tissue and leydig cell, destruction of basement membrane, complete detachment of spermatogenic cell from basement membrane, atrophy of spermatogenic cell, swelling spermatogenic cell, degeneration sertoli and leydig cell, cell death, congested blood vessels and hemorrhage. The statistical analysis at day seven shown significant decrease (P<0.05) in newborn weight compared with control group. Highly significant increase (P<0.001) in diameter of testes. Significant decrease (P<0.01) in diameter of seminiferous tubules. Significant decrease (P<0.05) in numbers of spermatogenic cell in seminiferous tubules. The conclusion: The findings of the present study show that therapeutic dose of methotrexate is capable of producing histological changes in newborn’s testis at day seven

The effect of mental speed drills on some visual abilities in shish weapon players
...Show More Authors

Achieving high achievement in the sport of fencing requires thinking, awareness and visual tracking, as visual tracking is one of the important visual abilities that a fencing player needs and is considered one of the special visual abilities as it contributes and helps in the correct motor, mental and mental performance and gives the fencing the ability to perfect and accomplished performance in training and competition. Where the research problem lies in the weak skill performance of the fencing players as a result of the weakness in possessing visual and mental abilities. The two researchers used the experimental method in a controlled manner (experimental and control groups) with a pre and post-test. The research community was identifie

Effect of prey type on some reproductive aspects in crustacean zooplankton Macrocyclops albidus (Copepoda:cyclopoida)
...Show More Authors

The experiment was conducted to investigate the effect of prey type (Artemia nauplii, mosquito larvae and paramecium) on some reproductive aspects in crustacean zooplankton M. albidus which included reproductive period, post reproductive period, period spend to egg appearance and the period from appearance of egg to nauplii releasing. Results revealed that females fed on mosquito larvae had the highest mean of postreproductive period and lowest mean of the period spend to egg appearance, which differed significantly (P < 0.05) compared with the means of females who fed on Artemia nauplii and paramecium on the other hand the differences were not significant in reproductive period and the period from appearance of egg to nauplii releasing.

The Effect of Magnetic Field with Nanofluid on Heat Transfer in a Horizontal Pipe
...Show More Authors

This work presents an experimental study of heat transfer and flow of distilled water and metal oxide nanofluid Fe3O4-distilled water at concentrations of (φ = 0.3, 0.6, 0.9 %) by volume in a horizontal pipe with constant magnetic field. All the tests are carried out with Reynolds number range (2900-9820) and uniform heat flux (11262-19562 W/m2). The results show that, the nanofluid concentration and magnetic intensity increase, the Nusselt number increases. The maximum enhancement in Nusselt number with magnetic nanofluid is (5.4 %, 26.4 %, 42.7 %) for volume concentration (0.3, 0.6, 0.9 %) respectively. The enhancement is maximized with magnetic intensity (0.1, 0.2, 0.3 tesla) respectively to (43.9, 44

Effect of Filler Types on Moisture Damage of Asphalt Mixtures
...Show More Authors

The filler in the asphalt mixture is essential since it plays a significant role in toughening and stiffening the asphalt. Changes in filler type can lead the asphalt mixtures to perform satisfactorily during their design life or degrade rapidly when traffic and environmental effects are considered. This study aims to assess the impact of filler types such as limestone dust (LS) and hydrated lime (HL) on Marshall characteristics and moisture damage in asphalt mixtures. Three different percentages of HL were employed in this study to partially replace the LS mineral filler: 1.5, 2.0, and 2.5% by aggregate weight. Furthermore, a control mixture was created with 7% LS by overall aggregate weight for the wearing course layer. The Marsha

Effect of Construction Joints on Performance of Reinforced Concrete Beams
...Show More Authors

Construction joints are stopping places in the process of placing concrete, and they are required because in many structures it is impractical to place concrete in one continuous operation. The amount of concrete that can be placed at one time is governed by the batching and mixing capacity and by the strength of the formwork. A good construction joint should provide adequate flexural and shear continuity through the interface.

In this study, the effect of location of construction joints on the performance of reinforced concrete structural elements is experimentally investigated.

Nineteen beam specimens with dimensions of 200×200×950 mm were tested. The variables investigated are the location of the construction joints
