introduction: in most bci articles which aim to separate movement imaginations, µ and β frequency bands have been used. in this paper, the effect of presence and absence of γ band on performance improvement is discussed since movement imaginations affect γ frequency band as well. methods: in this study we used data set 2a from bci competition iv. in this data set, 9 healthy subjects have perfor...

Genetic variation and inheritance of randomly amplified polymorphic DNA (RAPD) markers in female grass carp (Ctenopharyngodon idella) and male bighead carp (Hypophthalmichthys nobilis) and their F1 offspring hybrid have been studied. For this purpose, genomic DNA was extracted from muscle tissue according to phenol-chloroform method, and six decamer primers were used for amplifying polymorphic ...

Glutamate dehydrogenase becomes density labeled through the incorporation of deuterium and (15)N when detached oat leaves (Avena sativa var. Fulghum) are incubated in the presence of ammonia. The enzyme has been isolated by means of DEAE-cellulose chromatography, ammonium sulfate precipitation, isopycnic equilibrium centrifugation, and disc electrophoresis from leaves fed l-methionine-(35)S. Ra...

To test the possibility that individuals with and without plasma cholinesterase Cs isozyme have differences in neuromuscular sensitivity to succinylcholine chloride, we ~ramined the effects of succinylcholine in these two groups of patients. Sera from 491 adult patients were examined for presence of the plasma cholinesterase Cs isozyme by use o f electrophoresis with polyacrylamide ; 24 were posi-

Isozyme 3a of rabbit liver microsomal cytochrome P-450, also termed P-450ALC, was previously isolated in this laboratory from animals administered ethanol or imidazole, and the purified cytochrome was shown to function in the reconstituted system as an oxygenase in catalyzing the oxidation of ethanol and other alcohols. Although liver microsomes from animals treated in various ways exhibit incr...

Prodrug is a useful approach for improving the bioavailability of therapeutic agents through increased passive transport. Carboxylesterases (CESs, EC.3.1.1.1.) that show ubiquitous expression profiles play an important role in the biotransformation of ester-containing prodrugs into their therapeutically active forms in the body. High levels of CESs are found in the liver, small intestine and lu...

The genetic control of eight isozyme loci revealed by starch gel electrophoresis was studied through the analysis of three progenies derived from four tetraploid cultivars of Solanum tuberosum (groups Andigena and Tuberosum). Duplicate gene expression was found in seven (Got-A, Got-B, Pgd-C, Pgi-B, Pgm-A, Pgm-B and Pox-C) isozyme loci. In another isozyme gene (Adh-A), the parental genotypes wer...

Induction of differentiation of a human promyelocytic leukemic cell line (HL60) in culture is accompanied by changes in acid phosphatase (Acpase) activity. The increase in activity is less than twofold when the leukemic cells are stimulated by dimethylsulfoxide (DMSO) to differentiate into metamyelocytes and granulocytes but is eightfold when the cells are stimulated by the tumor-promoting agen...

The electrophoretic banding pattern of esterase isozymes were examined in eighteen different tissues of Nile tilapia after staining with α and β naphthyl acetate as substrate. The tissues were anterior-, mid-, tailmuscle (ventral and tip region), buccal muscle, stomach, fore-, mid-, hind-gut, liver, gill, heart, kidney, eye (lens), eye (iris), fore-, midand hindbrain. Altogether five bands name...

M A N Y examples of multiple forms of enzymes are now known (WR~BLEWSKI 1961; KAPLAN 1963; LATNER and SKILLEN 1968). These multiple forms were designated isozymes by MARKERT and MBLLER (1959). Some multiple forms are controlled by alleles of a given gene (ALLEN 1961; ALLEN, MISCH and MORRISON 1963; LEVINTHAL, SINGER and FETHEROLF 1962). Others result from the independent action of more than one...
