background: the purpose of the present in vitro study was to evaluate the effect of long term storage of conventional platelet concentrates (pcs) on major platelet receptors cd42b and cd41/cd61 by flow cytometry method and also measuring the overall platelet procoagulant activity status using platelet factor 3 (pf3) assay. materials and methods: six random units of conventional platelet concent...

The coat protein of Pseudomonas aeruginosa phage Pf3 is transiently inserted into the bacterial inner membrane with a single transmembrane anchor sequence in the N(out)C(in) orientation. The N-terminal sequence immediately flanking the membrane anchor contains one negatively charged residue, whereas the C-terminal hydrophilic segment has two positively charged residues. To investigate how the o...

The complete nucleotide sequence of the P + C mRNA of human parainfluenza virus type 3 (PF3) was determined by sequencing cDNA, viral genomic RNA and mRNA. The P + C mRNA is 2009 nucleotides in length, exclusive of poly(A), and contains two overlapping open reading frames (ORFs). The P + C mRNA encodes two proteins, the 602 amino acid nucleocapsid phosphoprotein P and the 199 amino acid non-str...

We present a first principles static and dynamical study of the transition metal hydride series MH4L3 (M = Fe, Ru and Os; L = NH3, PH3 and PF3), with a view to arriving at an understanding of how the variation in the electronic properties of the metal sites and ligands can influence the dynamics of the resulting complexes. A broad range of behaviour was observed, encompassing stable classical m...

The effects of Chinese pine (Pinus tabuliformis) on soil variables after afforestation have been established, but microbial community changes still need to be explored. Using high-throughput sequencing technology, we analyzed bacterial and fungal community composition and diversity in soils from three stands of different-aged, designated 12-year-old (PF1), 29-year-old (PF2), and 53-year-old (PF...

Enterococcus faecalis is one of the leading causes of nosocomial infections and is a common commensal organism in humans and other animals. In this study, we report a draft genome sequence for the E. faecalis strain PF3, isolated from Adélie penguin feces collected from Warriner Island, Antarctica.

Meloidogyne incognita is a plant pathogen causing root-knot nematodes disease in many crops worldwide. Due to the environmental threat on use of chemical fumigants, there need for biological control method using microbial antagonists disease. Therefore, this study was conducted screen and evaluate biocontrol potential P. fluorescens strains against nematodes. The effectiveness six viz., Pf1, Pf...

Partial single and double differential cross sections with their sums through direct and dissociative ionization of PF3 have been evaluated at fixed electron energies 100 and 200 eV, by using modified Jain-Khare semi-empirical approach. To the best of my knowledge no other data of differential cross sections are available for the comparison. I have also calculated integral ionization cross sect...

Previous studies of flagellar mutants have identified six axonemal polypeptides as components of a "dynein regulatory complex" (DRC). The DRC is though to coordinate the activity of the multiple flagellar dyneins, but its location within the axoneme has been unknown (Huang et al., 1982; Piperno et al., 1992). We have used improved chromatographic procedures (Kagami and Kamiya, 1992) and compute...
