[(125)I](T,G)-A--L-binding T cells have been studied in mice whose ability to mount an immune response to (T,G)-A--L is under control of the H-2-linked Ir-1A gene. Nonimmunized high and low responder mice have approximately the same frequency of T-ABC. Following immunization, T-ABC proliferated only in high responders, but not in low responders, indicating expression of Ir-1A in T cells. When, ...

Members of the ATP-binding cassette (ABC) superfamily of transporters have been implicated as major players in drug response. Single nucleotide polymorphisms (SNPs) in the ABC transporter genes may account for variation in drug response between individuals. Given the abundance of SNPs within the human genome, identification of functionally important SNPs is difficult. Here, we utilized signatur...

acid-binding capacity (abc) of a feed is the amount of acid required to reduce the ph of feed to a special level such as 3. all poultry feed ingredients used in this study were collected from feed mills in iran. the ph and abc were determined using the standard methods in deionized and magnetized water at room and body temperatures. the ph of most feed ingredients was raised in magnetized water...

a r t i c l e i n f o a b s t r a c t Keywords: EEG/ERP Adaptive filter SNR LMS RLS ABC In this paper, the Artificial Bee Colony (ABC) algorithm is applied to construct Adaptive Noise Canceller (ANC) for electroencephalogram (EEG)/Event Related Potential (ERP) filtering with modified range selection, described as Bounded Range ABC (BR-ABC). ERP generated due to hand movement is filtered through...

Synapsins are multidomain proteins that are critical for regulating neurotransmitter release in vertebrates. In the present study, two crystal structures of the C domain of rat synapsin I (rSynI-C) in complex with Ca(2+) and ATP reveal that this protein can form a tetramer and that a flexible loop (the "multifunctional loop") contacts bound ATP. Further experiments were carried out on a protein...

The notion of the Gergonne point a triangle in Euclidean plane is very well known, and study them isotropic setting has already appeared earlier. In this paper, we give two generalizations plane, several curves related to them. first generalization based on fact that for ABC its contact AiBiCi, there pencil circles such each circle km from lines AAm, BBm, CCm concurrent at Gm, where Am, Bm, Cm ...

The chondroitinases are bacterial lyases that specifically cleave chondroitin sulfate and/or dermatan sulfate glycosaminoglycans. One of these enzymes, chondroitinase ABC I from Proteus vulgaris, has the broadest substrate specificity and has been widely used to depolymerize these glycosaminoglycans. Biochemical and structural studies to investigate the active site of chondroitinase ABC I have ...

In their article titled ‘‘Estimating species trees using approximate Bayesian computation’’ Fan and Kubatko present an algorithm called ST-ABC to sample the posterior distribution of species trees (Molecular Phylogenetics and Evolution 59: 354– 363). The authors claim that ST-ABC is an approximate Bayesian computation (ABC) algorithm. Here, I argue that one of the steps in their algorithm diffe...

ATP-binding cassette (ABC) transporters constitute a large superfamily of integral membrane proteins that includes both importers and exporters. In recent years, several structures of complete ABC transporters have been determined by X-ray crystallography. These structures suggest a mechanism by which binding and hydrolysis of ATP by the cytoplasmic, nucleotide-binding domains control the confo...

We sought to explore the relationship between two subjective falls-risk assessment tools (Falls Efficacy Scale-International [FES-I] and Activities-Specific Balance Confidence [ABC] Scale) and functional, health-related, and body composition characteristics. A total of 245 community-dwelling people aged 60 to 88 years underwent assessments for subjective falls risk (using the FES-I and ABC Scal...
