When the glutelin protein fraction of rice (Oryza sativa L.) seeds was fractionated by sodium dodecyl sulfate polyacrylamide gel electrophoresis, three size classes of proteins, 51 kilodaltons (kD), 34 to 37 kD, and 21 to 22 kD, as well as a contaminating prolamine polypeptide of 14 kD were detected. Antibodies were raised against these proteins and employed in studies to determine whether a pr...

The role of beta-endorphin (beta-EP) in ethanol-altered NK cell cytolytic activity is studied using male Fischer-344 rats as an animal model. Ethanol was administered for 1, 2, 3, or 4 wk in a liquid diet containing 8.7% ethanol (v/v), which means that 37% of the total calories were derived from ethanol. Rats treated with ethanol for 1 wk showed an increase in hypothalamic and plasma levels of ...

BACKGROUND Gerstmann-Sträussler-Scheinker disease is a rare form of prion disease. OBJECTIVE To determine the prion mutation in a 51-year-old man without a family history of neurologic disease who died from Gerstmann-Sträussler-Scheinker disease. PATIENT AND METHODS The patient was a 51-year-old man who died after a 9-year illness characterized by dementia and eventually ataxia. Neuropathol...

Beet powdery mildew incited by Erysiphe betae is a serious foliar fungal disease of worldwide distribution causing losses of up to 30%. In the present work, we searched for resistance in a germplasm collection of 184 genotypes of Beta vulgaris including fodder (51 genotypes), garden (60 genotypes), leaf (51 genotypes), and sugar (22 genotypes) beet types. Resistant genotypes were identified in ...

Preparations of gamma-aminobutyrate (GABA)/benzodiazepine receptor from pig cerebral cortex are composed of three major bands of polypeptides (51, 55 and 57 kDa) which are purified in a ratio of approx. 2:1:1 respectively. Treatment of purified receptor preparations with cyclic AMP-dependent protein kinase resulted in major incorporation of 32P into the 55 kDa band only. The maximum incorporati...

Acinetobacter baumannii (A. baumannii) is an important nosocomial pathogen in healthcare institutions. β-Lactamase-mediated resistance is the most common mechanism for carbapenem resistance in A. baumannii. The aim of this study was to determine the antibiotic resistance pattern, to detect OXA encoding genes, class A, bla PER-1, and to detect the presence of ISAba1. A total of 124 A. baumannii ...

Infections due to carbapenem-resistant Klebsiella pneumoniae represent a growing problem nationally. In our study, we aimed to examine carbapenem-resistant K. pneumoniae with multiple resistance isolated in the intensive care unit of our hospital. Isolates were investigated for the presence of oxacillinase and metallo-beta lactamase genes with a view to determining the clonal relationship betwe...
