We tested the hypothesis that single nucleotide polymorphisms (SNPs) within genes of the NF-κB pathway are associated with altered clinical outcome of septic shock patients. We genotyped 59 SNPs in the NF-κB pathway in a discovery cohort of septic…

A protein of mass 7643 Da and sequence identical to that of subunit c, the pore part, of the mitochondrial adenosine triphosphate synthase complex, was co-purified with cholesterol in crystals formed from a chloroform/methanol extract of bovine…

A technique is described for the computer simulation of the motion of 10000 simulated molecules. The number of computer operations per time-step is proportional to the number of simulated particles even though the force of interaction may be long…

A continuous wave near-infrared spectroscopy (NIRS) instrument for brain-computer interface (BCI) applications is presented. In the literature, experiments have been carried out on subjects with such motor degenerative diseases as amyotrophic…

Using (133)Cs+ NMR, we developed a technique to repetitively measure, in vivo, Na(+)-K(+)-ATPase activity in endothelial cells. The measurements were made without the use of an exogenous shift reagent, because of the large chemical shift of 1.36…

Members of the Mad family of bHLHZip proteins heterodimerize with Max and function to repress the transcriptional and transforming activities of the Myc proto-oncogene. Mad:Max heterodimers repress transcription by recruiting a large multi-protein…

The crystal structure of an HIV-1 trans-activation response region (TAR) RNA fragment containing the binding site for the trans-activation protein Tat has been determined to 1.3-A resolution. In this crystal structure, the characteristic UCU bulge…

Measurement of local myocardial O(2) consumption (VO(2)) has been problematic but is needed to investigate the heterogeneity of aerobic metabolism. The goal of the present investigation was to develop a method to measure local VO(2) using small…

We have recorded (13)C NMR spectra of selectively 3-(13)CAla-, 1-(13)CAla-, or 1-(13)CVal-labeled synthetic transmembrane peptides of bacteriorhodopsin (bR) and enzymatically cleaved C-2 fragment in the solid and bilayer. It turned out that these…

We recorded 13C NMR spectra of type I and IV collagens in the anhydrous and hydrated states, in order to confirm our previous assignment of peaks, and to analyze the mode of partial renaturation of soluble collagens by hydration, as well as rapid…
-
Selectively 13C-enriched free and protein-bound flavins in the oxidized and two-electron reduced state were investigated by the 13 C nuclear magnetic resonance technique. FMN in aqueous solution and N-(3)-menthyl-2',3'4,'5'-tetraacetylriboflavin in…

Amyloid-β(1-42) (Aβ) is thought to be a major mediator of the cognitive deficits in Alzheimer's disease. The ability of Aβ to inhibit hippocampal long-term potentiation provides a cellular correlate of this action, but the underlying molecular…

Calbindin D(9k) is a dicalcium binding protein consisting of two helix-loop-helix EF-hand motifs joined together by a flexible linker region where one metal ion can bind to each of the two loops. A proline residue at position 43 in the linker region…

The cAMP-dependent protein kinase anchoring protein, d-AKAP1, has two N-terminal splice variants. The shorter forms (N0, d-AKAP1a, and -1c) target to mitochondria, and the longer forms (N1, d-AKAP1b, and -1d) with 33 additional residues N-terminal…

Aeolian deposits in the Wahiba Sands, Sultanate of Oman, reveal patterns of atmospheric circulation over the past 160,000 years. Luminescence dating indicates a correlation of dune activity with periods of low global sea level and decreased monsoon…

This study provides evidence that, in the soluble fraction from buffer-washed pea thylakoids, one form of soluble carbonic anhydrase (CA) is associated with rubisco in a stromal protein complex. On native-PAGE gels, it is present as a protein band…

A17 amacrine cells of the cat retina have been penetrated with horseradish peroxidase (HRP)-filled microelectrodes and their light responses recorded. These cells depolarize in sustained fashion to steps of light. Viewed in retinal wholemounts,…
-
Molecular self-assembly offers a means of spontaneously forming complex and well-defined structures from simple components. The specific bonding between DNA base pairs has been used in this way to create DNA-based nanostructures and to direct the…

The coronavirus spike (S) protein mediates infection of receptor-expressing host cells and is a critical target for antiviral neutralizing antibodies. Angiotensin-converting enzyme 2 (ACE2) is a functional receptor for the coronavirus (severe acute…
