however, the conventional gold recovery process is cyanidation, due to the recent environmental laws; researchers are looking for alternative methods for the recovery of gold. furthermore, the copper anode slime is one of the most important secondary sources of gold (about 1200 ppm). so, the main objective of the current work is gold separation from copper anode slime as a rich secondary source...

multiple myeloma (mm) characterized by proliferation of plasma cells in bone marrow and production of monoclonal immunoglobulin's. recently, arsenic trioxide (ato), has been considered for treatment refractory mm. we assessed the safety and efficacy of ato for patients with refractory mm. a phase 2, study of arsenic trioxide was conducted in 12 mm patients, whose refractory to two standard ther...

In this study, slag penetration into a magnesia refractory monolithic was investigated by the crucible test method. A synthetic calcium aluminate slag system has been used to study commercial magnesia mix refractory for 1, 2, 3, 4, 5 and 6 hours at 1450°C and 1600°C. It has been shown that the penetration rate is controlled by a diffusion mechanism at 1450°C. In this case, capillaries are the ...

According to the unique properties and many applications of nano gold powder, it was prepared from an acid leaching tail solution. The low value residual gold ions existed in acid leaching tail solution in Mouteh gold mine in Iran with fellow heavy metals as pollutants (Fe2+, Cu2+, and Zn2+). Preparation of nano gold particles is achieved by two steps: First, by addition of ammonia as separatio...

objective(s):   gold nanoparticles (gnps) command a great deal of attention for biomedical applications nowadays. the data about the degree of toxicity and the accumulation of gold nanoparticles in-vivo is not enough to judge.  materials and methods:  a total of 32 healthy male wistar rats were randomly divided into 4 including: three gnp-treated and one control group. groups 1, 2 and 3 receive...

INTRODUCTION Surgical septal myectomy is thought to be the gold standard of treatment for obstructive hypertrophic cardiomyopathy (HCM) with obstruction symptoms refractory to optimal medical therapy. In Europe, during the last 2 decades, myectomy has been set aside, while alcohol septal ablation has been widely promoted. In this paper, we analyze our first experience of surgical septal myectom...

Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder, caused by mutations in the NF1 gene. The NF1 gene encoding neurofibromin protein, which is strongly expressed in the nervous system and with the role as a negative regular of the ras proteins signal. All six cases with neurofibromatosis type 1 were clinical and laboratory investigated. The frequently symptoms are "café au lait" s...

patients with acute myeloblastic leukemia (aml) with monosomy 7 are a group of patients with refractory aml who have a very poor prognosis. therefore, rationally designed new therapies, including metronomic chemotherapy regimen with histidine deacetylase inhibitors (valporic acid, atra) are being investigated as potential treatments for the population of refractory cases of aml. herein, we repo...
