background: diabetes mellitus is one of the most important diseases in all over the world. insulin and its receptor are found in specific area of cns with a variety of regions-specific functions different from its role in direct glucose regulation in the periphery. the hippocampus and cerebral cortex distributed insulin and insulin receptor has been shown to be involved in brain cognitive funct...
The field of nanoparticle delivery systems for nutrients and nutraceuticals with poor water solubility has been expanding, almost exponentially, over the last five years, and some of these technologies are now in the process of being incorporated in food products. The market projections for these technologies suggest a multifold increase in their commercial potential over the next five years. T...
Enzymatic ligation of discrete nanoparticle-DNA conjugates creates nanoparticle dimer and trimer structures in which the nanoparticles are linked by single-stranded DNA, rather than by double-stranded DNA as in previous experiments. Ligation was verified by agarose gel and small-angle X-ray scattering. This capability was utilized in two ways: first, to create a new class of multiparticle build...
مقدمه : با توجه به وجود نتایج ضد و نقیض در مطالعات در ارتباط با تاثیر آتورواستاتین بر روی قند خون و کنترل دیابت در بیماران دیابتی و اثرات مفید درمانی استاتینها بر روی فرآیندهای التهابی و متابولیسم ، اثرات آتورواستاتین به میزان 40 mg روزانه به مدت سه ماه بر روی قند خون ،مقاومت به انسولین، مارکرهای التهابی و آدیپوکینها، در بیماران دیابتی مورد ارزیابی قرار گرفت. روش کار : 88 بیمار دیابتی نوع دو ت...
Organic-sulfur-zinc hybrid materials were prepared via polycondensation of Zn(OAc)2 and trithiols bearing various alkyl groups. A soluble nanoparticle could be obtained by the polycondensation using a trithiol bearing octadecyl moieties. The good dispersing ability as nano-scaled particles was confirmed by dynamic light scattering and atomic force microscopy analyses. This hybrid nanoparticle w...
We have controllably positioned, with nanometre precision, single CdSe quantum dots referenced to a registration template such that the location of a given nanoparticle on a macroscopic (≈1 cm(2)) sample surface can be repeatedly revisited. The atomically flat sapphire substrate we use is particularly suited to optical measurements of the isolated quantum dots, enabling combined manipulation-sp...
A three-dimensional micromechanical finite element model is developed to study the viscoelastic behavior of the silica nanoparticle/polyimide nanocomposites. The representative volume element (RVE) of the model consists of three phases including silica nanoparticle, polyimide matrix and interphase which surrounds the nanoparticle. The interphase region is created due to the interaction between ...
Gold nanoparticles have shown great promise as therapeutics, therapeutic delivery vectors, and intracellular imaging agents. For many biomedical applications, selective cell and nuclear targeting are desirable, and these remain a significant practical challenge in the use of nanoparticles in vivo. This challenge is being addressed by the incorporation of cell-targeting peptides or antibodies on...
Nanotechnologies have been proposed for a variety of environmental applications, including subsurface characterization, enhanced oil recovery, and in situ contaminant remediation. For such applications, quantitative predictive models will be of great utility for system design and implementation. Electrolyte chemistry, which can vary substantially within subsurface pore waters, has been shown to...
OBJECTIVE To prepare and evaluate the liver-targeted drug delivery system of Bufalin with higher liver uptake and stronger antitumor activity against hepatocellular carcinoma. METHODS Bufalin-loaded bovine serum albumin nanoparticle was prepared by desolvation method, to investigate the in vitro release performance and to evaluate the pharmacokinetic and tissue distribution. The antitumor act...
