Lending support to the hygiene hypothesis, epidemiological studies have demonstrated that allergic disease correlates with widespread use of antibiotics and alterations in fecal microbiota ("microflora"). Antibiotics also lead to overgrowth of the yeast Candida albicans, which can secrete potent prostaglandin-like immune response modulators, from the(More)
Several models of anthrax pathogenesis suggest that early in the infectious process Bacillus anthracis endospores germinate and outgrow into vegetative bacilli within phagocytes before being released into the blood. Here, we define the respective contributions of three phospholipases C (PLCs) to the pathogenesis of B. anthracis. Genetic deletions of the(More)
Pulmonary clearance of the encapsulated yeast Cryptococcus neoformans requires the development of T1-type immunity. CCR2-deficient mice infected with C. neoformans develop a non-protective T2 immune response and persistent infection. The mechanisms responsible for this aberrant response are unknown. The objective of this study was to define the number,(More)
OBJECTIVE We sought to identify genetic determinants within human immunodeficiency virus type 1 (HIV-1) gp120 that differentiate viral species in brain from those in lymphocytes. STUDY DESIGN/METHODS Polymerase chain reaction (PCR) was used to amplify gp120 genes from paired brain and T-cell isolates from two infants and two adults with dementia.(More)
The mechanisms underlying induction of immune dysregulation and chronic fungal infection by a transient tumor necrosis factor alpha (TNF-alpha) deficiency remain to be defined. The objective of our studies was to determine the potential contribution of neutropenia and immature dendritic cells to the immune deviation. Administration of an anti-TNF-alpha(More)
Circadian rhythm-dependent cell cycle progression produces daily variations in radiosensitivity. This literature review aims to summarise the data on whether radiotherapy outcomes differ depending on administration time. A literature search was conducted on Ovid Medline, Embase, Cochrane Central Register of Controlled Trials and PubMed using key words such(More)
INTRODUCTION The purpose of the present study was to investigate the efficacy of an ondansetron rapidly dissolving film (rdf) in the prophylaxis of radiation-induced nausea and vomiting (rinv). Rapidly dissolving film formulations facilitate drug delivery in circumstances in which swallowing the medication might be difficult for the patient. METHODS(More)
