Microcin B (McB) is a ribosomally synthesized antibacterial peptide. It contains up to nine oxazole and thiazole heterocycles that are introduced posttranslationally and are required for activity. McB inhibits the DNA gyrase, a validated drug target. Previous structure-activity analyses indicated that two fused heterocycles located in the central part of McB are important for antibacterial acti...

Medullary carcinoma of the breast (MCB) is a morphologically and biologically distinct subtype of human breast cancer that, despite cytologically anaplastic features, has a more favorable prognosis than other types of breast cancer at similar stages of differentiation. It has been proposed that the improved clinical outcome is due, at least in part, to the presence of a prominent lymphoplasmacy...

We sought to extend earlier work by examining whether there are ordinary variations in human maternal caregiving behavior (MCB) that are related to stress reactivity in infants. We observed 185 mother-infant dyads and used standard coding systems to identify variations in caregiving behavior. We then created two extreme groups and found that infants receiving low-quality MCB showed more fearful...

Monochlorobimane (MCB) has been used as a glutathione (GSH) specific fluorescent probe capable of delineating GSH heterogeneity in cellular systems. Generally, low concentrations of MCB (less than 50 microM) have been used to quantitatively label GSH in rodent cell lines. Incubation of the hamster cell lines, CHO AB1 and V79, with 10 microM MCB labeled 75 and 39% of the reduced GSH pool, respec...

A novel technique has been developed to monitor Escherichia coli contamination on carcasses using membrane filtration and m-ColiBlue24 (mCB). mCB is a membrane filtration medium that simultaneously detects total coliforms and E. coli (EC) in a period of 24 +/- 4 h. A study was conducted, using a sponge method to obtain samples from pork carcasses and the excision technique to remove samples fro...

and Implications In January 1997, the USDA-FSIS mandated Escherichia coli (EC) testing in all processing plants to monitor surface contamination of beef, pork, and poultry carcasses. A novel technique that uses membrane filtration (MF) and m-ColiBlue24 (mCB) to determine the amount of EC contamination on a carcass was developed. Sponges from pork carcasses and excision samples from beef carcass...

Marine cloud brightening (MCB) has been suggested as a possible solar radiation management approach to geoengineering the Earth’s climate in order to offset anthropogenic global warming. We discuss the utility of field experiments to test MCB. These experiments, if appropriately designed, would provide an unprecedented controlled environment to not only test MCB, but to understand aerosol impac...

The DNA repair genes RAD54 and UNG1 have MCB elements in their promoters and are shown to be cell cycle regulated. Their transcripts are coordinately expressed with RNR1, ribonucleotide reductase, a MCB-regulated gene known to be expressed in late G1. However, no evidence was obtained for a direct role of MCB elements in DNA repair. Of the proteins that bind and activate MCB elements, only muta...

Here we report on the draft genome sequence of Serratia marcescens strain MCB associated with Oscheius sp. MCB (Nematoda: Rhabditidae) isolated from South African soil. S. marcescens strain MCB has 5,304,212-bp genome size with 4,877 genes and a G+C content of 59.1%.

In this paper, we present a new narrow block mode of operation, the Masked Code Book (MCB), that can be efficiently deployed in disk encryption applications. MCB is characterized by its high-speed in comparison to current state of the art narrow block modes of operation. It is about 25% faster than XTS (when AES is the underlying cipher). Furthermore, MCB does not face the limitations of XTS.
