Introduction: A noninvasive method of detecting exposure of phosphatidylserine (PS) on the external surface of the plasma membrane such as nuclear imaging could assist the diagnosis and therapy of apoptosis related pathologies. The most studied imaging agent for apoptosis is Annexin V so far. Because of limitations of Annexin V other agents have been introduced such as small peptides and molecu...

the starch based films have some disadvantages such as weak mechanical and poor water barrier properties that restrict their applications in food packaging. in the present research, the polyvinyl alcohol (povh), as a compatible polymer, and montmorillonite (mmt) nanoclay, as a nanofiller, were added to plasticized starch film (ps) to improve its properties and also to produce ps-mmt-pvoh nanoco...

The ability of 8 picosecond pulse lasers for three dimensional direct-writing in the bulk of transparent dielectrics is assessed through a comparative study with a femtosecond laser delivering 600 fs pulses. The comparison addresses two main applications: the fabrication of birefringent optical elements and two-step machining by laser exposure and post-processing by chemical etching. Formation ...

Several epidemiological studies have reported that passive smoking (PS) is a public health hazard and perhaps increases the risk of heart disease. This study evaluated the relationship between female coronary heart disease and PS among married women who described themselves as non-smokers in an area of south-east Iran. Using household exposure to tobacco smoke as an estimate of PS, a hospi...

Hybrid protein-metal junctions have potential applications in nanoelectronic devices which can make use of the outstanding catalytic properties of the proteins. Specifically, photoactive proteins are promising materials for optoelectronic applications, such as solar cells and photodetectors.1 However, very little is known about the electronic coupling between proteins and metal surfaces. Even l...
