UNLABELLED An important first line of defense against Candida albicans infections is the killing of fungal cells by professional phagocytes of the innate immune system, such as polymorphonuclear cells (PMNs) and macrophages. In this study, we employed live-cell video microscopy coupled with dynamic image analysis tools to provide insights into the complexity of C. albicans phagocytosis when mac...

titer wells with direct counting of surviving larvae after incubation. Killed larvae appeared to be lysed. Verification of the microplate assay was obtained by demonstrating complete loss of infectivity of larvae incubated with leukocytes and immune serum. In the presence of optimal immune serum concentrations, purified neutrophils or eosinophils achieved _95% killing of larvae at cell:larva ra...

background: with respect to the prevalence of leishmaniosis in our country and the problems occurred in the therapeutic approaches and also with respect to the previous successful reports of paromomycin efficacy in this regard, the present study was conducted to determine the effects of paromomycin and gentamicine sulphate on promastigotes of leishmania major.materials and methods: it was an ex...

The MIC and MSC (minimum spirocheticidal concentration) and killing rate for Borrelia burgdorferi, the etiological agent of Lyme disease, were assessed for cefodizime in comparison with ceftriaxone, minocycline, azithromycin, roxithromycin, and ciprofloxacin. The range of cefodizime MICs was greater than those of azithromycin and roxithromycin but comparable to those of ceftriaxone and minocycl...

whereas others divide at least once before death. Cells selected for their capacity to survive prolonged periods of hyperthermia are killed at approximately the same rate during subsequent heat treatments as cells that had not been heated previously. Hyperthermic cell killing is reduced in cells that are heated in the presence of certain compounds that are inhibitors of DNA and protein synthesi...

Spores and vegetative forms of a strain of B. megatherium were irradiated by ultraviolet light of the wave lengths 2536 A, 2803 A, and 3132 A. The killing rate of both bacteria and spores is exponential, in agreement with irradiation results on other bacteria. Twice as much incident energy is needed to kill the spores as the vegetative forms (50 per cent death). The absorbed energy per bacteriu...

We consider the evolution of Green's function of the one-dimensional Schrödinger equation in the presence of the complex potential −ikδ(x). Our result is the construction of an explicit time-dependent solution which we use to calculate the time-dependent survival probability of a quantum particle. The survival probability decays to zero in finite time, which means that the complex delta potenti...
