Background: Breast Cancer (BC), the second leading cause of cancer mortality after lung cancer and varied across the world due to genetic and environmental factors. In this study, we evaluated the interaction between the polymorphisms in genes encoding enzymes of folate metabolism: methylenetetrahydrofolate reductase (MTHFR), methionine synthesis reductase (MTR) with the BC prognostic factors. ...

BACKGROUND The incidence of Down syndrome (DS) in Egypt varies between 1:555 and 1:770 and its screening by triple test is becoming increasingly popular nowadays. Results, however, seem inaccurate due to the lack of Egyptian-specific information needed for risk calculation and a clear policy for programme implementation. Our study aimed at calculation and validation of the triple marker medians...

Article history: Received on: 25/09/2013 Revised on: 02/11/2013 Accepted on: 25/11/2013 Available online:29/11/2013 The present study was carried out to assess the effect of plant's extract on Ehrlich ascites carcinoma (EAC) and its influence on redox status and tissue injury on liver. Among five groups of albino mice, three were treated with plant's extract, in addition, a group treated with t...

Background: The incidence of breast and cervical cancers is growing rapidly among Egyptian women. In this context, we assessed the prevalence of, and factors associated with the lack of knowledge among Egyptian females of performing breast self–examination (BSE) and unawareness of cervical smear cancer screening services. Methods: Secondary data analysis was performed on a representative popula...

The anaerobic biodegradability of domestic sewage for four Egyptian villages and four Egyptian cities was determined in batch experiments. The results showed that the biodegradability of the Egyptian-villages sewage (73%) was higher than that of the cities (66%). The higher biodegradability of the soluble COD of village sewage (69%) as compared to that of the cities (46%) was the reason for the...

The purpose of this paper is to examine the effect of social networking sites’ (SNSs) characteristics on Egyptians’ perception and attitude towards the 25/30 uprisings, also known as the “Arab Spring”. Data were obtained from 422 Egyptian university students using SNS by means of questionnaire. Structural Equation Modeling (SEM) was conducted to test the research hypotheses. The study results i...

The genetic structure of the Egyptian peach fruit fly (Bactrocera zonata (Saunders) (Diptera: Tephritidae)) population was analyzed using total RNA from adult females. A portion of mitochondrial cytochrome oxidase I (COI), 369 bp was amplified using RT-PCR, and was sequenced and analyzed to clarify the phylogenetic relationship of B. zonata established in Egypt. The data suggested that the gene...

— Wide Area Monitoring Systems (WAMS) utilizing synchrophasor measurements is considered one of the essential parts in smart grids that enable system operators to monitor, operate, and control power systems in wide geographical area. On the other hand, high-speed, reliable and scalable data communication infrastructure is crucial in both construction and operation of WAMS. Universal mobile Tele...

A joint speech signal enhancement based on singular value decomposition filter after spectral subtraction (SSVD) is proposed in this paper. The residual noise after spectral subtraction, which results for audible musical noise, is reduced further by SVD filter. The matrix size in spectral domain can be reduced half, and larger step-length adopted by SVD filter in spectral domain leads to lower ...
