OBJECTIVES To screen for low bone mineral density among young adult Saudi women using quantitative ultrasound (QUS) and exploring the high risk groups. Methods: A cross-sectional study was performed on 279, 20-36 years old female students and employees of Taibah University, Al Madinah Al Munawwarah, Kingdom of Saudi Arabia between January and May 2014. The study included bone status assessed us...

Using a cluster sampling method, a group of menopausal women from three geographic areas in Tehran were asked to participate in the study. Demographic data was obtained using a questionnaire. Subjects were than referred to perform bone mass densitometry (BMD). The relationship between various variables (i.e. age of menarche, number of years of endogenous estrogen exposure, ... ) with minera...

In this study, we show that high-salt exposure dramatically increases chick mortality during embryo development. As embryonic mortality at early stages mainly results from defects in cardiovascular development, we focused on heart formation and angiogenesis. We found that high-salt exposure enhanced the risk of abnormal heart tube looping and blood congestion in the heart chamber. In the presen...

Background and objectives: Alveolar macrophages (AMs) are targets for respiratory syncytial virus (RSV) infection in vivo and in vitro. However, only a minority ofAMs are permissive to acute RSV infection in vitro, and it is unknown whether this permissiveness may be related to the degree of cellular maturation that is achieved in vivo. Methods: By using density gradient centrifugation, in whic...

UNLABELLED Pre- and postsynaptic cardiac sympathetic function is altered in ischemic congestive heart failure (CHF). Whether there is a presynaptic-to-postsynaptic mismatch or whether mismatch is related to adverse cardiac events is unknown. METHODS In 13 patients with ischemic CHF and 25 aged-matched healthy volunteers, presynaptic function was measured by PET of (11)C-meta-hydroxyephedrine ...

Introduction: Exposure to the low frequency electric and magnetic fields (ELF-EMF) is very common in workers occupied in the combined cycle power plant during work shifts  The present study aimed to measure ELF-EMF flux density among shift and non-shift workers, determine job stress among workers and office workers, and identify major factors associated with job stress in the studied groups. M...

High-density lipoproteins (HDL) have received considerable interest as a target for the development of novel anti-atherosclerotic agents beyond conventional approaches to lipid lowering. While a number of approaches have focused on modifying remodeling and expression pathways implicated in the regulation of HDL levels, an additional approach involves simply infusions of delipidated HDL. Several...

electromagnetic radiation emitted by cell-phones is a new health hazard, especially when they are used inside closed metal bodies such as cars, elevators etc. the modern wireless devices like bluetooth further enhance the effect of this radiation. the present studies were taken to get quantitative information about the actual power density levels to which a human brain is exposed inside a vehic...

Cutaneous malignant melanomas with histologic evidence of an associated nevus (N+) may have a different risk factor profile from that of melanomas without it (N-). To address this question, a case-only analysis of 932 people with cutaneous malignant melanoma was done to identify etiologic and other factors associated with N+ melanoma. Evidence of an associated nevus was found in 36% of melanoma...
