Pretargeting techniques that are based on the sequential administrations of bispecific antitumor/antimetal chelate antibodies (BS-MAbs), a blocker to saturate the anti-chelate binding sites of the BS-MAb still present in the circulation, and the radiolabeled chelate are suitable to increase tumor-to-normal tissue contrasts and enable positron emission tomography (PET) as an imaging method. As d...

An experiment was conducted to investigate the effects of supplemental copper (Cu) chelates (methionine, chitosan and yeast) on the performance, nutrient digestibility, serum IgG level, gizzard erosion, Cu content in the liver and excreta and the level of total cholesterol in breast muscle and serum of broiler chickens. Two hundred and forty hatched broiler chickens (Ross 208) were assigned to ...

the kinetics of the de complexation by hydroxyl ions of some pervanadyl, molybdate and tungstate amionocarboxylate complexes have been studied spectrophotometrically by means of a stopped flow technique. the chelate groups used were the iminodiacetic acid (ida), ethylenediarnine-n,n' -diacetic acid (edda), nitrilotriacetic acid (nta) and ethylene diamine-n,n,n' ,n'-tetraacetic ac...

The article summarizes the results of a three-year study on feasibility and effectiveness use herbicides soil insurance action microfertilizer Quantum - Molybdenum Chelate infestation yield soybeans. It was established that in agrophytocenosis soybean, mixed type formed, which dicotyledonous young weeds predominated. Weed control efficiency 75.5% 60 days after application Frontier Optima. Spray...

The addition of AlCl3 to four-coordinate boranes of the general formula (C-N-chelate)BCl2 results in halide abstraction and formation of three-coordinate borenium cations of the general formula [(C-N-chelate)BCl]+. The latter react with both arylstannanes and arylsilanes by boro-destannylation and -desilylation, respectively, to form arylated boranes. Catalytic quantities of AlCl3 were sufficie...

Study of the nuclear magnetic resonance spectra of glyoxaldihydrazone in dimethylsulfoxide and deuterochlorofonn leads to the conclusion that this compound exists predominantly in non-chelate structure

In the solvent extraction of metal cations into ionic liquids, use of Brønsted acid-type chelate extractants has some advantages including simplicity in controlling extraction selectivity by selecting suitable aqueous phase pH values and simple back-extraction recovery of the extracted metals using acid solutions. In this review, various fundamental and applied research on metal extraction usin...
