staphylococcus aureus is an opportunistic pathogen and remains a common cause of burn wound infections. different studies have shown that entrapment of plant-derived compounds into liposomes could increase their anti-staphylococcus aureus activity. silymarin is the bioactive extract from the known plant silybum marianum l. the objective of this study was to evaluate efficacy of silymarin in fre...

OBJECTIVE To study the sterilizing effect and mechanism of electrolyzed-oxidizing water (EOW) and electrolyzed-reductive water (ERW) for Bacillus subtilis var. niger (ATCC9372) and Escherichia coli (8099). METHODS The generations of EOW and ERW were made in the ion membrane electrolysis cell. The sterilization manner was the suspension quantitative germicidal test. RESULTS The killing rate ...

the paper contains the first report on the biology of snail-killing flies (sciomyzidae) in khuzestan. it is based on field and laboratory studies conducted during november 1971 and april 1973, as well as field observations in may 1972, at the dezful medical research station. additional biological information obtained during studies is given for pherbellia fuscipes (macaquart), p.grisescens (mei...

Two in vitro tests, the serum killing level and the serum bactericidal rate assays, were evaluated for correlation with therapeutic efficacy in the rabbit model of Staphylococcus aureus endocarditis. Animals were treated with nafcillin alone and in combination with tobramycin or gentamicin. Both were effective therapies, but rapidity of vegetation sterilization by the single and combined regime...

Background: Multiple myeloma (MM) is a malignant plasma cell proliferative disorder with limited immunotherapy treatment because of T cell dysfunction. Objective: To investigate the immunomodulatory function of bone marrow mesenchymal stromal cells (MM-BMSCs) on CD8+ T cells. Methods: Proliferation and cytotoxicity were detected by c...

We consider birth-death processes on the nonnegative integers, where {1, 2, . . . } is an irreducible class and 0 an absorbing state, with the additional feature that a transition to state 0 (killing) may occur from any state. Assuming that absorption at 0 is certain we are interested in additional conditions on the transition rates for the existence of a quasi-stationary distribution. Inspired...

It has been difficult to measure efficacy of T cell-based vaccines and to correlate efficacy of CD8T cell responses with protection against viral infections. In part, this difficulty is due to our poor understanding of the in vivo efficacy of CD8T cells. Using a recently developed experimental method of in vivo cytotoxicity we investigated quantitative aspects of killing of peptide-pulsed targe...
