BACKGROUND Whether fractures observed in healthy children are associated with microstructural alterations and strength deficit that persists by the end of the growth period is not established. Considering the importance of pubertal timing in bone development, we also quantified the fracture risk related to later menarcheal age (MENA). PARTICIPANTS AND METHODS We followed 124 healthy girls fro...

This paper uses panel cointegration techniques to examine the causal relationship between renewable energy consumption, economic growth and CO2 emissions for a group of 12 MENA countries covering the annual period 1975-2008. The Granger-causality results indicate that there is no causal relationship between these variables in short run except a unidirectional causality running from renewable en...

PURPOSE OF REVIEW A volume of quality HIV data has materialized recently in the Middle East and North Africa (MENA). This review provides a thematic narrative of the patterns of HIV infection transmission in this region in light of these data. RECENT FINDINGS Tens of integrated bio-behavioral surveillance surveys among hard-to-reach key populations at higher risk have been conducted in MENA i...

Polysaccharide (PS) based meningococcal vaccines are primarily evaluated by physicochemical methods to ensure batches are consistently manufactured. As PS content is determined by different methods across numerous laboratories, there is a need for International Standards (IS) to calibrate the assays. Following the successful introduction of the WHO Meningococcal group C (MenC) IS in 2011, NIBSC...

BACKGROUND The contribution of BRCA1 mutations to both hereditary and sporadic breast and ovarian cancer (HBOC) has not yet been thoroughly investigated in MENA. METHODS To establish the knowledge about BRCA1 mutations and their correlation with the clinical aspect in diagnosed cases of HBOC in MENA populations. A systematic review of studies examining BRCA1 in BC women in Cyprus, Jordan, Egy...

The protests that swept the Arab Middle East and North Africa (MENA) are expected to have influenced two key civic attitudes fundamental to well-functioning democracies: trust and tolerance. However, systematic comparative assessments of the general patterns and particularities in this region are rare. This contribution theorizes the uprisings’ impact and presents new society-level measurements...

BACKGROUND Actomyosin-based contractility acts on cadherin junctions to support tissue integrity and morphogenesis. The actomyosin apparatus of the epithelial zonula adherens (ZA) is built by coordinating junctional actin assembly with Myosin II activation. However, the physical interaction between Myosin and actin filaments that is necessary for contractility can induce actin filament turnover...

In this commentary, we elaborate on the main points that Karamouzian and colleagues have made about HIVdata scarcity in Middle Eastern and North African (MENA) countries. Without accessible and reliable data, no epidemic can be managed effectively or efficiently. Clearly, increased investments are needed to bolster capabilities to capture and interpret HIV surveillance data. We believe that thi...
