A rod-shaped, marine, phototrophic, purple sulfur bacterium containing gas vesicles was isolated from a marine solar saltern at Kakinada, India. Cells of strain JA134(T) are Gram-negative, non-motile rods, with vesicular intracytoplasmic membranes, and the strain has an absolute requirement for NaCl for growth. Bacteriochlorophyll a and the carotenoid okenone are present as photosynthetic pigme...

Nineteen patients in acute left ventricular power failure following acute myocardial infarction were given support with intraaortic balloon pumping and underwent cardiac catheterization. Hemodynamic response to disastolic augmentation, results of left ventriculography, and observations of selective coronary arteriography were evaluated to determine which patients could survive without operation...

The key-generation algorithm for the RSA cryptosystem is specified in several standards, such as PKCS#1, IEEE 1363-2000, FIPS 186-3, ANSI X9.44, or ISO/IEC 18033-2. All of them substantially differ in their requirements. This indicates that for computing a “secure” RSA modulus it does not matter how exactly one generates RSA integers. In this work we show that this is indeed the case to a large...

DNA, isolated from two samples of human liver obtained from a suspected dimethylnitrosamine poisoning, contained 1363 to 1373 micromol of 7-methylguanine per mol of guanine and 273 to 317 micromol of O6-methylguanine per mol of guanine. Liver and kidney DNA obtained from unrelated cases contained no detectable methylated purines. From the DNA methylation levels, it is estimated that the dimethy...

The 3D structure of the 18-kDa transmembrane (TM) protein TSPO (translocator protein)/PBR (peripheral benzodiazepine receptor), which contains a binding site for benzodiazepines, is important to better understand its function and regulation by endogenous and synthetic ligands. We have recently determined the structure of mammalian TSPO/PBR in complex with the diagnostic ligand PK11195 [1-(2-chl...

The ERD2 gene, which encodes the yeast HDEL (His-Asp-Glu-Leu) receptor, is essential for growth (Semenza, J. C., K. G. Hardwick, N. Dean, and H. R. B. Pelham. 1990. Cell. 61:1349-1357; Lewis, M. J., D. J. Sweet, and H. R. B. Pelham. 1990. Cell. 61:1359-1363). SED5, when present in multiple copies, enables cells to grow in the absence of Erd2p. Sequence analysis of SED5 reveals no significant ho...

Objective—We previously reported that interferons (IFNs) regulate transcription of HIF-1 in human endothelial cells (ECs), linking immunity and hypoxia. Prolyl hydroxylases (PHDs) regulate expression of HIF-1 in response to hypoxia. We examined whether IFNs affect PHD expression and whether PHDs regulate the EC response to IFNs. Methods and Results—Human cell cultures were treated with various ...
