The Great Pyramid or Khufu's Pyramid was built on the Giza Plateau (Egypt) during the IV(th) dynasty by the pharaoh Khufu (Cheops), who reigned from 2509 to 2483 BC(1). Despite being one of the oldest and largest monuments on Earth, there is no consensus about how it was built(2,3). To better understand its internal structure, we imaged the pyramid using muons, which are by-products of cosmic rays that are only partially absorbed by stone(4-6). The resulting cosmic-ray muon radiography allows us to visualize the known and potentially unknown voids in the pyramid in a non-invasive way...

Clifford Odimegwu, Sunday A Adedini
Anthropological explanations of demographic outcomes have emphasized the need to understand how community structures contribute to those outcomes. However, studies on fertility dynamics in Africa have largely focused on micro-level factors, thus ignoring the influence of community contexts. Using the most recent Demographic and Health Survey data from Egypt (Northern Africa), Cameroon (Middle Africa), Kenya (Eastern Africa), Nigeria (Western Africa) and Zimbabwe (Southern Africa), the study employed multilevel Poisson regression models to examine the influence of community factors on African fertility levels and patterns...

BACKGROUND AND AIM OF WORK: Sickle cell disease (SCD) is an inherited disease of the beta globin gene. The β(S) globin gene haplotypes are Senegal, Benin, Bantu, Cameroon, Arab-Indian and atypical haplotypes. In SCD, stroke is a life-threatening event in both adults and children. In light of paucity of studies on β(S) globin gene haplotypes in Egypt, we aimed to determine β(S) globin gene haplotypes in children with SCD and study their impact on stroke risk. METHODS: Fifty-two SCD patients were included in the study, they were 26 males and 26 females with age range from 3 to 18 years old...

In this study, we isolated and characterized three phages named as Salmacey1, Salmacey2 and Salmacey3, infecting multi drug resistant Salmonella serovars isolated from broilers in Egypt. The most prevalent Salmonella serovars were S. typhimurium, S. enteritidis, and S. kentucky. All these Salmonella serovars were found to be resistant to more than two of the ten antimicrobial agents tested. Only S. kentucky was found to be resistant to seven antimicrobial agents. Examination of these phage particles by transmission electron microscopy (TEM), demonstrated that two phages (Salmacey1, Salmacey2) were found to belong to family Siphoviridae, and Salmacey3 was assigned to the family Myoviridae...

Faba bean necrotic yellows virus (FBNYV) (genus Nanovirus; family Nanoviridae) has a genome comprising eight individually encapsidated circular single-stranded DNA components. It has frequently been found infecting faba bean (Vicia faba L.) and chickpea (Cicer arietinum L.) in association with satellite molecules (alphasatellites). Genome sequences of FBNYV from Azerbaijan, Egypt, Iran, Morocco, Spain and Syria have been determined previously and we now report the first five genome sequences of FBNYV and associated alphasatellites from faba bean sampled in Tunisia...

BACKGROUND: Hepatitis C virus (HCV) infection represents a major public health burden with diverse epidemics worldwide, but at present, only a minority of infected persons have been tested and are aware of their diagnosis. The advent of highly effective direct acting antiviral (DAA) therapy, which is becoming available at increasingly lower costs in low and middle income countries (LMICs), represents a major opportunity to expand access to testing and treatment. However, there is uncertainty as to the optimal testing approaches and who to prioritize for testing...

BACKGROUND: Women's empowerment is often used to explain changes in reproductive behavior, but no consideration is given to how reproductive events can shape women's empowerment over time. Fertility may cause changes in women's empowerment, or they may be mutually influencing. Research on women's empowerment and fertility relies on cross-sectional data from South Asia, which limits the understanding of the direction of association between women's empowerment and fertility in other global contexts...

This article revisits the carbon dioxide (CO2) emissions-GDP causal relationships in the Middle Eastern and North African (MENA) countries by employing the Rossi (Economet Theor 21:962-990, 2005) instability-robust causality test. We show evidence of significant causality relationships for all considered countries within the instability context, whereas the standard Granger causality test fails to detect causal links in any direction, except for Egypt, Iran, and Morocco. An important policy implication resulting from this robust analysis is that the income is not affected by the cuts in the CO2 emissions for only two MENA countries, the UAE and Syria...

Honeybee losses have been attributed to multiple stressors and factors including the neonicotinoid insecticides (NIs). Much of the study of hive contamination has been focused upon temperate regions such as Europe, Canada and the United States. This study looks for the first time at honey, pollen and bees collected from across the Nile Delta in Egypt in both the spring and summer planting season of 2013. There is limited information upon the frequency of use of NIs in Egypt but the ratio of positive identification and concentrations of NIs are comparable to other regions...
