the effects of mobile phone exposure on humans, due to its potential health hazards, have become the focus of interest since many years ago. the effect of global system for mobile communications (gsm 900 mhz) on growth and proliferation rate of mesenchymal stem cells was assessed at the different distances and intensities of radiation. a subscriber identity module (sim) card was inserted to thi...

BACKGROUND Overexpression of the myristolated alanine-rich C kinase substrate (MARCKS) occurs in vascular proliferative diseases such as restenosis after bypass surgery. MARCKS knockdown results in arrest of vascular smooth muscle cell (VSMC) proliferation with little effect on endothelial cell (EC) proliferation. We sought to identify the mechanism of differential regulation by MARCKS of VSMC ...

The history of the International Atomic Energy Agency (IAEA) and the Nuclear Non-Proliferation Treaty (NPT) demonstrate that peaceful nuclear energy is a myth. As our January 2007 Briefing, “Civil Nuclear Power and Nuclear Weapons Proliferation”, explains promoting ‘peaceful’ nuclear power has accelerated nuclear weapons proliferation. Nuclear reactors in India, Pakistan, Israel, and North Kore...

In order to improve the shoot proliferation rate of ‘Dwarf Cavendish’ banana shoot tip cultures, polyethylene glycol (PEG6000) was employed at concentrations of 2, 4, and 6% (w/v). The medium without PEG was considered as negative control. An increasing of shoot proliferation was achieved in MS medium containing 2% PEG. Furthermore, application of 2% PEG significantly increased the shoot dry we...

Abstract Background Diabetic foot ulceration is a serious chronic complication of diabetes mellitus characterized by high disability, mortality, and morbidity. Platelet-rich plasma (PRP) has been widely used for diabetic wound healing due to its content growth factors. However, application limited the rapid degradation The present study aimed evaluate efficacy combined adipose-derived mesenchym...

In abiotic degradation the action of light radiation is one of the most important parameters, because polymers undergo degradation due to the action of light (natural or artificial). The aim of this study was to investigate the degradation rate for samples of polypropylene (PP) modified with an organic pro-degradant submitted to ageing in a natural environment and to accelerated ageing test. Th...

Widespread use of Mg-Zn-Ca alloys in clinical orthopedic practice requires improvement their mechanical properties—in particular, ductility—and enhancement bioactivity for accelerated osteoreconstruction. The alloy was studied two structural states: after homogenization and equal-channel angular pressing. Immersion potentiodynamic polarization tests showed that the corrosion rate not increased ...

Multiple myeloma (MM) is a clonal proliferation of plasma cells invading the bone marrow and secreting monoclonal immunoglobulin. In order to study epidemiological biological biochemical characteristics MM, we carried out retrospective work on cohort 50 cases collected at Avicenna Military Hospital in Marrakesh, during period 5 years (from January 2013 December 2017). Our included 32 men (64%) ...

The accelerated development of information and communication technologies (ICT) over the last three decades has encouraged researchers to analyse impact this phenomenon on labour market. potential decline in employment resulting from proliferation ICT may reduce access basic energy services even lead poverty form inability heat apartment as needed, allocating a significant part revenues expense...

Polycaprolactone (PCL) is one of the most recognized polymeric materials used for bone tissue engineering scaffold fabrication. This study aims to evaluate effects molecular weight (Mn) PCL on degradation kinematics, surface, microstructural, thermal, mechanical, and biological properties 3D printed scaffolds. Surface were investigated considering water-in-air contact angle nanoindentation test...
