BACKGROUND Mitochondria play pivotal roles in cell death; the loss of mitochondrial membrane potential (delta psi(m)) is the earliest event that commits the cell to death. Here, we report novel real-time imaging of delta psi(m) in individual cardiomyocytes within perfused rat hearts using 2-photon laser-scanning microscopy, which has unique advantages over conventional confocal microscopy: grea...

In quantum state filtering one wants to determine whether an unknown quantum state, which is chosen from a known set of states, [|psi(1)>, em leader,|psi(N)>], is either a specific state, say |psi(1)>, or one of the remaining states, [|psi(2)>, em leader,|psi(N)>]. We present the optimal solution to this problem, in terms of generalized measurements, for the case that the filtering is required ...

The sequence of tRNA tyrosine from the fission yeast Schizosaccharomyces pombe is pCUCCUGAUm1 GGUG psi AGDDGGDDAUCACACor (psi) CCGGUG psi Ai6 AACCGGUUGm7 GUm5C GCUAGT psi CGm1 AUUCUGGUCAGGAGACCAOH. This sequence differs in 30 nucleotides from the tRNA-Tyr seqence of the budding yeast Saccharomyces cerevisiae. It has a unique anticodon stem of only four GC base pairs. The normal fifth pair posit...

OBJECTIVE To assess if the Agency for Healthcare Research and Quality  patient safety indictors (PSIs) could be used for case findings in the International Classification of Disease 10th revision (ICD-10) hospital discharge abstract data. DESIGN We identified and randomly selected 490 patients with a foreign body left during a procedure (PSI 5-foreign body), selected infections (IV site) due ...

The last 82 nucleotides of the 6.3 kb genomic RNA of plant turnip yellow mosaic virus (TYMV), the so-called 'tRNA-like' domain, presents functional, structural and primary sequence homologies with canonical tRNAs. In particular, one of the stem-loops resembles the TPsi(pseudouridine)-branch of tRNA, except for the presence of a guanosine at position 37 (numbering is from the 3'-end) instead of ...

Private Set Intersection (PSI) allows two parties to compute the intersection of private sets while revealing nothing more than the intersection itself. PSI needs to be applied to large data sets in scenarios such as measurement of ad conversion rates, data sharing, or contact discovery. Existing PSI protocols do not scale up well, and therefore some applications use insecure solutions instead....

To gain insights into the molecular details of photosystem I (PSI) biogenesis, we characterized the PsbP-domain protein1 (ppd1) mutant of Arabidopsis thaliana that specifically lacks PSI activity. Deletion of PPD1 results in an inability of the mutant to grow photoautotrophically and a specific loss of the stable PSI complex. Unaltered transcription and translation of plastid-encoded PSI genes ...

Recombinant plasmids pLP psi as and pCP psi as were constructed by positioning the Moloney murine leukemia virus (M-MuLV) proviral packaging (psi) sequences in reverse orientation under the transcriptional regulation of lymphotropic promoter/regulatory elements from the M-MuLV long terminal repeat or the cytomegalovirus immediate-early region. Linear fragments containing the antisense psi and t...

PSI is a large protein-pigment complex located in the thylakoid membrane in cyanobacteria, plants, and algae. Although the structure and components of PSI are well characterized, mechanisms that orchestrate its assembly are poorly understood. In this study, we discovered a novel nucleus-encoded protein, Photosystem I Assembly3 (PSA3), that is required for PSI accumulation. PSA3 is conserved amo...

The relationship between the magnitude of the transmembrane electrical potential and the uptake of [14C]gentamicin was examined in wild-type Staphylococcus aureus in the logarithmic phase of growth. The electrical potential (delta psi) and the pH gradient across the cell membrane were determined by measuring the equilibrium distribution of [3H]tetraphenyl-phosphonium and [14C]acetylsalicylic ac...
