Full hemolytic activity in Newcastle disease virus (NDV) suspensions is not obtained without pretreatment of the virus by techniques such as freezing and thawing or extensive dialysis (Granoff and Henle, J. Immunol. 75:322, 1954). Girardi (Virology 9:488, 1959) has reported that fluorocarbon treatment unmasks polyoma virus hemagglutinin. Results are reported here which show that fluorocarbon tr...

OBJECTIVE To simultaneously model plasma dilution and urinary output in female volunteers. METHODS Ten healthy female non-pregnant volunteers, aged 21-39 years (mean 29), with a bodyweight of 58-67 kg (mean 62.5 kg) participated. No oral fluid or food was allowed between midnight and completion of the experiment. The protocol included an infusion of acetated Ringer's solution, 25 ml/kg over 3...

BACKGROUND Hypertonic saline hydroxyethyl starch (HH) has been recommended for first line treatment of hemorrhagic shock. Its effects on coagulation are unclear. We studied in vitro effects of HH dilution on whole blood coagulation and platelet function. Furthermore 7.2% hypertonic saline, 6% hydroxyethylstarch (as ingredients of HH), and 0.9% saline solution (as control) were tested in compara...

Load theory of attention proposes that distractor processing is reduced in tasks with high perceptual load that exhaust attentional capacity within task-relevant processing. In contrast, tasks of low perceptual load leave spare capacity that spills over, resulting in the perception of task-irrelevant, potentially distracting stimuli. Tsal and Benoni (2010) find that distractor response competit...

Echinocandins are a group of antifungal agents that target 1,3-beta-glucan synthase, causing disruption of mold growth at cells compromising tips and branch points. In part because echinocandins do not induce clear growth inhibition end points using broth dilution techniques, methods to test susceptibility have not yet been standardized. We developed a novel susceptibility assay that measures g...

In sensitized subjects, provocation tests to latex may induce severe systemic reactions and even anaphylactic shock. It is probable that part of the risk is due to the difficulty in grading the stimulating dose and in starting from very low levels of exposure. To identify the aetiological agent of work-related asthma in four nurses with previous allergic contact urticaria to latex surgical glov...

Abstract Due to the SARS-CoV-2 pandemic renewed attention has been directed towards viral neutralization assays and neutralizing antibodies quantification, for vaccine pre-clinical trials determining efficacy over time. The gold standard assess antibody titer is plaque reduction test, an end-point assay which evaluates highest serum dilution that neutralizes replication, by inspecting cytopathi...

The cell-mediated immune system function was studied both in vitro and in vivo in 20 healthy women who had been taking combined oral contraceptives for an average of 2.8 years. All patients received intradermal injections of a 1/100 dilution of Candida albicans, a 1/100 dilution of mumps skin test antigen, a 1/10 dilution of tetanus toxoid fluid, and a 1/200 dilution of phytohemagglutinin-P. ...
