in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...

In this chapter, non-autonomous oscillators are considered as mappings from input functions of time to a circle’s worth giving the state function time. This view is justified using theory normally hyperbolic submanifolds dynamical systems. It illuminates phenomena phase-locking, synchronisation and chimera; it allows an extension concept coupling; hierarchical aggregation treatment in networks ...

The amorphous aggregation of proteins is associated with many phenomena, ranging from the formation of protein wine haze to the development of cataract in the eye lens and the precipitation of recombinant proteins during their expression and purification. While much literature exists describing models for linear protein aggregation, such as amyloid fibril formation, there are few reports of mod...

Abstract Introduction Platelet aggregation plays a significant role in the etiology of cardiovascular diseases. Therefore, treatments to inhibit platelet aggregation can reduce the risk of coronary thrombosis. Several studies indicated that garlic can inhibit platelet aggregation. This study aimed to determine the effect of garlic in comparison with Plavix on platelet aggregation. Materials ...

protein aggregation and precipitation is associated with many debilitating diseases including alzheimer's, parkinson's, and light-chain amyloidosis. β-casein, a member of the casein family, has been demonstrated to exhibit chaperone-like activity to protect protein form aggregation. hofmeister salts (lyotropice series) are a class of ions which have an effect on the solubility and also the stab...

Query auto-completion (QAC) is a common interactive feature for assisting users during query formulation. Following each query input keystroke, QAC suggests queries prefixed by the input characters; allowing the user to avoid further cognitive and physical effort if any are acceptable. To rank suggestions, QAC approaches typically aggregate past query popularity to determine the likelihood of a...

Polyglutamine (polyGln) aggregation is implicated in the disease progression of Huntington's disease and other expanded CAG repeat diseases. PolyGln aggregation in vitro follows a simple nucleated growth polymerization pathway without apparent complications such as populated intermediates, alternative assembly pathways, or secondary nucleation phenomena. Previous analysis of the aggregation of ...

Although nonlinear optical spectroscopy of nanostructures, nanomaterials, and nanomedicines has been widely used to observe study the nature (NLO) phenomena, field improve for single nanostructure system. However, it is extremely difficult investigate behaviors materials because setup in experiment obligate a high resolution imaging arrangement overcome diffraction limit problem. This paper pre...
