Hepatocellular Carcinoma in Upper Egypt: A Retrospective Study
Abstract Background: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer deaths worldwide. The incidence of HCC is highest in Asia and Africa, where the endemic high prevalence of hepatitis B and hepatitis C strongly predisposes to the development of chronic liver disease and subsequent development of HCC. Aim of the Work: Our study was designed to characterize ... Read more

Genetic Variability of Hepatitis C Virus in South Egypt and Its Possible Clinical Implication
Egypt is one of the countries with very high rates of hepatitis C virus (HCV) related morbidity and mortality. However, little is known about geographical and clinical differences in genetic variability of HCV in Egypt. Using direct sequencing and phylogenetic analysis of partial core/E1 and NS5B regions of the HCV genome, HCV genotype/subtype was determined in 129 HCVinfected patients residing ... Read more

Petrographic and geochemical studies on amphibolites occurrence in the Eastern Desert, Egypt.
Amphibolite from Barud, Meatiq and Abu Markhat ares located in the Central Eastern Desert of Egypt were investigated. Geologically, the amphibolites occur as intercalating lenses, slabs and elongated bands in the infrastructural granite-gneisses. Geochemical data revealed that the analysed amphibolites are of igneous protoliths derived from basalts and basaltic-andesites. They display tholeiitic, calc-alkaline and low-K tholeiites affinites and are thus ... Read more

Petrochemistry of the Pan-African basement rocks from Humr Waggat area, Central Eastern Desert, Egypt.
The basement suite of the Humr Waggat area is consists of Pan-African serpentinites, calc-alkaline metavolcanics, metagabbros and post orogenic granites. geochemically, the serpentinites are of hurzburgite parentage and enrcihed in Ni which bears non-consanguineous relationships with the tectonically incorporated metavolcanics and metagabbros which of calc-alkaline geochemistry, formed in an island arc setting. Their chemical data shows their common genetic origin. ... Read more

.case fatalities rate Southern Egypt Stroke Study
INTRODUCTION Stroke now ranks as the second leading cause of death and the first cause of morbidity allover the world. Among all the neurological diseases of adult life, stroke clearly ranks first in frequency and importance, at least 50% of the neurological disorders in a hospitalized patients are of this type [1- 3]. Despite advances in medical care of stroke ... Read more

Seasonal variation and enrichment of metals in sediments of Rosetta branch, Nile River, Egypt
This study investigated heavy metal pollution in sediments of the Rosetta branch of the River Nile of Egypt to quantify the toxic distribution potential of metals into the surrounding environment. Sediment samples were collected at 9 sites during in four seasons. Organic matter and total metal concentrations were determined using loss on ignition and inductively coupled plasma spectrometry, respectively. Principal ... Read more

Flood hazard assessment and heavy metal distributions around Um Gheig mine area, Eastern Desert, Egypt
This study focuses on wadi Um Gheig and its associated Pb-Zn mine to quantify the possible dispersion pathways of heavy metals to the surrounding environment. The morphometric drainage system parameters were specified by ArcGIS 9.3. A total of 21 samples were collected and analyzed using XRF, XRD, ICP-OES and SEM. Different enrichment indices were applied to specify the degree and ... Read more

Heavy metals seasonal variability and distribution in Lake Qaroun sediments, El-Fayoum, Egypt
This study was carried out to investigate the seasonal variability and distribution of heavy metals “HMs” (Fe, Mn, Co, Cr, Cu, Ni, Pb, Zn and V) in the bottom sediments of Lake Qaroun, in Egypt. The samples were collected from 10 sites in summer and winter seasons in 2015. Total metals concentrations were measured using inductively coupled plasma spectrometer. Multivariate ... Read more

Chemical characteristics and assessment of groundwater quality in Halayieb area, southeastern part of the Eastern Desert, Egypt
Halayieb area is located at the southeastern corner on the border between Egypt and Sudan. The area has very important strategic aspects to Egypt. Groundwater is the only source of fresh water in the area. The hydrogeochemical characterizations of groundwater in the area were carried out, to assess the quality of groundwater for its suitability for drinking and irrigation purposes. ... Read more
