Prophylactic and Ameliorative Effect of 𝑁-Acetylcysteine on Doxorubicin-Induced Neurotoxicity in Wister Rats
Doxorubicin (DOX) is an anthracycline antibiotic and a quinone-containing chemotherapeutic drug used for various types of cancers. However, as with most anticancer drugs, it causes many toxic effects, one of them is cognitive impairment. The present study investigated the prophylactic and ameliorative effect of n-acetylcysteine (NAC) against DOXinduced neurotoxicity in rats. Rats were divided into four groups. Control group: rats ... إقراء المزيد

Tympanic membrane grafting, underlay periosteal versus inlay cartilage grafts: a comparative study
Abstract Various grafting materials and different ways of positioning have been described for tympanic membrane (TM) reconstruction. However, there are few clinical trials comparing cartilage and periosteal grafts. Aims: A comparison between underlay periosteal grafting (UPG) and inlay cartilage grafting (ICG) of TM. Material and Methods: A retrospective controlled trial. Group A, included 88 patients underwent UPG. Group B, included ... إقراء المزيد

Correlation between Unconfined Compression Strength (UCS) and Index Properties of Soil in Assiut Governorate, Egypt
Experimental tests are very important to determine the engineering properties of soils in geotechnical engineering. Special expertise and care are required to perform these tests. The unconfined compression test is also one of them. Thus, there is a need to develop models to quickly predict the unconfined compression strength of soils. The researchers attempted to develop correlations to predict the ... إقراء المزيد

Association between Helicobacter pylori Infection and Iron Deficiency Anemia among School-Age Children in Sohag University Hospital, Upper Egypt
Background: Helicobacter pylori (H. pylori ) infection has been suggested as a cause of iron deficiency anemia (IDA) refractory to iron therapy. Objective: The aim of this work was to evaluate the association between H. pylori infection and IDA among school-age children. Subjects and Methods: This was a prospective case-control study conducted for one year starting from March 2015 and ... إقراء المزيد

Oleanolic acid methyl ester, a novel cytotoxic mitocan, induces cell cycle arrest and ROS-Mediated cell death in castration-resistant prostate cancer PC-3 cells
Oleanolic acid derivatives exhibit potent anticancer activities against numerous types of cancer. However, the antitumor activity of oleanolic acid methylester (OAME), an oleanolic acid derivative, against prostate cancer has not been studied. Hence, the present work was conducted to study the anticancer activities of OAME. Viability assay showed that treatment of cancer cells with OAME induced a significant cell death ... إقراء المزيد
