The laboratory and clinical evaluation of a potassium nitrate-saturated disk for the rapid detection of nitrate reductase production in anaerobes was investigated. The optimal disk concentration and incubation time were determined by utilizing triplicate sets of quadrant plates prepared with supplemented brucella (Difco) blood agar and swabbed with a 24-h broth (BBL; 135 C thioglycolate) suspen...

A conjugated polymer known for high stability (poly[benzimidazobenzophenanthroline], coded as BBL) is examined as a photoanode for direct solar water oxidation. In aqueous electrolyte with a sacrificial hole acceptor (SO3(2-)), photoelectrodes show a morphology-dependent performance. Films prepared by a dispersion-spray method with a nanostructured surface (feature size of ∼20 nm) gave photocur...

In February 2000, Becton Dickinson Biosciences initiated a study to evaluate a potential new product, Herrold's Egg Yolk Agar with Mycobactin J and arnphotericin B, nalidixic acid, and vancomycin (BBL HEYA-MANV). The study involved laboratories which produced their own similar product, and compared the ability of the two media to support the growth of Mycobacterium avium subsp. paratuberculosis...

<p class="06ContentAbstract">Innovation in learning is needed by combining a approach and classroom setting model to solve the problem of low student achievement representation abilities. It can also be used as an effort overcome problems aspect attitude, for example, math anxiety. This study was aimed (1) describe effectiveness brain-based with think pair share (BBL+TPS); (2) find out di...

SETTING Mycobacterial growth in media to which inhibitory substances are added has been used in species identification. Growth of the Mycobacterium tuberculosis complex (MTC) is inhibited by rho-nitrobenzoic acid (PNB), whereas non-tuberculous mycobacteria (NTM) are resistant. Thiophene-2-carboxylic acid hydrazide (TCH) is useful in the differentiation of MTC when performed together with other ...

The bifunctional protein complex, cysteine synthetase, in Salmonella tyPhimurium is composed of the enzymes serine transacetylase and 0-acetylserine sulfhydrylase. A point mutation (BBl) in the structural gene for serine transacetylase results in diminished catalytic activity of both components of the complex. Enzyme inactivation studies using either specific 0-acetylserine sulfhydrylase antise...

Implementation of hydraulic fracturing dramatically altered the fundamentals in the oil and gas markets. A new technology rst got implemented in the natural gas market, but by 2012 unprecedentedly low gas prices forced most exploration rms to switch to shale oil exploration. Large capital expenditure on drilling activity resulted in the growth of oil production in the US, and likely triggered t...

Tobacco (Nicotiana tabacum) plants synthesize nicotine and related pyridine-type alkaloids, such as anatabine, in their roots and accumulate them in their aerial parts as chemical defenses against herbivores. Herbivory-induced jasmonate signaling activates structural genes for nicotine biosynthesis and transport by way of the NICOTINE (NIC) regulatory loci. The biosynthesis of tobacco alkaloids...

We previously showed that soybean lectin (SBL) releases cholecystokinin (CCK) and have now asked whether other dietary lectins have this effect and if extracellular calcium is involved. Lectins and vehicle were first infused into the duodenum of anesthetized rats. The CCK response to vehicle was 3.1 ± 0.6 pmol/l ( P < 0.05 vs. basal). SBL and peanut lectin (PNL) (84 μg/ml) significantly increas...

Electrophoretic analysis of the major seed protein, G1 globulin, from four strains of Phaseolus vulgaris L. revealed a three-banded pattern for two strains having a high methionine content (BBL 240 and PI 302,542). The other two strains (PI 207,227 and PI 229,815) known to have a lower seed methionine content, had a two-banded subunit pattern for the G1 globulin. Analytical ultracentrifugation ...
