Sarcoidosis is a granulomatous disease whose outcome varies from spontaneous remission to chronic refractory disease. Provided that steroids represent the gold standard as a first line treatment, many immune suppressants drugs are currently used in the disease management. However, refractory disease is still a great challenge. Rituximab is an anti-CD20 chimeric monoclonal antibody, currently us...

A significant part of the primary gold reserves in world is contained sulphide ores, many types which are refractory processing. The deposits ores will be main potential source production future. and silver can associated with micro- nano-sized inclusions Au Ag minerals as well isomorphous, adsorbed other species noble metals (NM) not thoroughly investigated. For gold-bearing Urals, distributio...

Abstract The arsenic-bearing gold ore in Anhui, China is an extremely refractory ore, and the cyanide leaching rate of concentrate only 30%. mineralogical factors low were discussed by process analysis. results demonstrate that contains 20.30 g/t gold, 3.39% arsenic, 29.80% sulfur, 4.10% iron. Gold exists occurrence states metallic mineral-wrapped gangue fissure which account for 64.90%, 8.31%,...

Some idea of the possibilities of microbeam techniques can be illustrated by examining the following example of a run of mine gold ore sample. Milling and bulk chemical analysis of the ore will provide major and minor element analysis as well as the gold grade. More detailed chemistlY can also reveal the presence of trace elements that may be advantageous or deleterious to downstream processing...

Lower urinary tract symptoms from benign prostatic hyperplasia are a very prevalent disease process which affects more than 40% of men over age 60. When LUTS from BPH become medically refractory, transurethral resection of the prostate and prostatectomy have been the gold standards for treatment. While the efficacy of these procedures has been clearly delineated, they are also associated with s...
