Cytochrome b-245, the putative terminal component of the specialized cidal oxidase system of phagocytes, was measured in human monocytes in culture. There was a dramatic synthesis of the cytochrome, which increased by 27.3 +/- 2.0 pmol/day per 10(7) cells. This represents an increase of about 40%/day in the early stages and an overall 7-fold increase after 16 days. The protein content increased...

The determination of stance in two-sided discussions/debates in online debate forums is a new and interesting problem in opinion mining. We target the task of classifying stance in ideological debates on online debate forums, and this is a rather challenging problem due to the nature of debate setting and the language used. (Hasan and Ng, ) had introduced the notion of using ideology as an inte...

A cellular role and the mechanism of action for small GTPase Arl1 have been defined. Arl1-GTP interacts with the GRIP domains of Golgin-97 and Golgin-245, a process dependent on conserved residues of the GRIP domains that are important for Golgi targeting. The switch II region of Arl1 confers the specificity of this interaction. Arl1-GTP mediates Golgi recruitment of Golgin-97 in a switch II-de...

The aim of this study was to estimate the genetic divergence between African cowpea lines from the Cowpea Germplasm Bank of Embrapa Meio-Norte, Brazil. The morphoagronomic diversity of 57 cowpea lines was assessed using multivariate analysis. The germplasm was evaluated in August 2009 using a randomized block design with three replications based on the following traits: number of pods per pedun...

Human immunodeficiency virus type-1 (HIV-1), a member of the lentivirus family, encodes two regulatory genes (tat, rev) and four accessory genes (vif, vpr, vpu, nef) in addition to three common retroviral structural genes (gag, pol, env). Viral protein R (Vpr) is a small 14-kDa protein of 96 amino acids. Vpr is incorporated into the virions through its interaction with the p6 region of HIV-1 Ga...
