to confirm the side-effects of gold sodium thiomalate (gstm), we carried out a retrospective study examining 102 consecutive patients with rheumatoid arthritis attending the rheumatology unit of hafez hospital, shiraz, iran, in whom gstm was initiated between 1983-1989. only patients with classical or definite ra (ara criteria) we(e included in this study. patients were categorized as having de...

Introduction: Radiotherapy involves all methods that can provide a special amount of ionizing radiation to malignant tissue with the assumption that minimal damage to healthy tissues is achieved. We are looking for a valuable and reliable method to measure the absorption dose and also the ability to measure the absorption dose distribution in three dimensions, which today is th...

An original synthetic route, based on the combination of a single-source precursor, UV-photodegradation and inverse w/o miniemulsion, is used to prepare Au nanoparticles (NPs) dispersed on titania. The source of the nanocomposite materials is the photolabile single-source precursor AuCl4(NH4)7[Ti2(O2)2(cit)(Hcit)]2·12H2O, which is suspended in a w/o miniemulsion consisting of different surfacta...

Gold-poly(methyl methacrylate) nanocomposites are prepared by an in situ method, by irradiating spin-coated films containing the polymer and the gold precursor dissolved in acetone. The reduction of gold ions results in the formation of Au that nucleates and grows within the polymer film. It is shown that, depending on the energy source, gold nanoparticles with different shapes can be formed. N...

Gold-mining may play an important role in the maintenance of malaria worldwide. Gold-mining, mostly illegal, has significantly expanded in Colombia during the last decade in areas with limited health care and disease prevention. We report a descriptive study that was carried out to determine the malaria prevalence in gold-mining areas of Colombia, using data from the public health surveillance ...

Electrokinetically driven fluid transport was evaluated within three-dimensional hybrid nanofluidic-microfluidic devices incorporating Au-coated nanocapillary array membranes (NCAMs). Gold NCAMs, prepared by electroless gold deposition on polymeric track-etched membranes, were susceptible to gas bubble formation if the interfacial potential difference exceeded approximately 2 V along the length...

Plasmon resonant metal nanoparticles on substrates have been considered for use in several nanophotonic applications due to the combination of large field enhancement factors, broadband frequency control, ease of fabrication, and structural robustness that they provide. Despite the existence of a large body of work on the dependence of the nanoparticle plasmon resonance on composition and parti...

Several methods have been developed for gold exploration in the past, among which biological base method is known to be the most efficient with least expenses. This method can also be used for latent gold prospects exploration. In the present study, the possibility of applying Bacillus cereus frequency in soil as a biological marker was investigated for the exploration of latent gold prospectin...

Post-editing has traditionally been used to improve the quality of MT output to make it usable. More recently, post-editing has also been shown to be useful for automatic evaluation of MT systems. As an alternative to current automatic evaluation metrics, such as BLEU and NIST, which are criticized for not having a high correlation with human judgments, minimal post-editing of MT output provide...

At the ISOLDE on-line isotope separation facility, the resonance ionization laser ion source (RILIS) can be used to ionize reaction products as they effuse from the target. The RILIS process of laser step-wise resonance ionization of atoms in a hot metal cavity provides a highly element selective stage in the preparation of the radioactive ion beam. As a result, the ISOLDE mass separators can p...
