AIMS To investigate the effects of temperature, pH, water activity (aw) and CO2 concentration on the growth of Rhizopus oligosporus NRRL 2710. METHODS AND RESULTS Hyphal extension rates from mycelial and spore inocula were measured on media with different aw (approximately 1.0, 0.98 and 0.96) and pH (3.5, 5.5 and 7.5) incubated at 30, 37 or 42 degrees C(More)
A patient with cutaneous mastocytosis had intractable pruritus but no visible skin lesions. Skin biopsies and urinary histamine and prostaglandin D2 metabolite assays confirmed the diagnosis. Adding therapy with psoralens and ultraviolet A to the antihistamine regimen markedly decreased the patient's pruritus. In patients with pruritus, flushing, syncope,(More)
We investigated the respiratory heat and water loss in 24 asthmatic patients who performed bicycle exercise while inspiring air conditioned to varying temperatures and water contents. Measurements of peak expiratory flow and forced expiratory volume in 1 s were made at rest, during and after exercise to determine changes in airways resistance. Respiratory(More)
Fibers in foods are complex carbohydrates. There are several types of fiber, but, for the purpose of mechanistic insight into their mode of protective action in carcinogenesis, classification into two broad types, soluble and insoluble fibers, is warranted. Soluble fibers are present in fruits, vegetables, and certain grains like oats. This type of fiber(More)
Endogenously generated circadian rhythms are synchronized with the environment through phase-resetting actions of light. Starlight and dim moonlight are of insufficient intensity to reset the phase of the clock directly, but recent studies have indicated that dim nocturnal illumination may otherwise substantially alter entrainment to bright lighting(More)
The effect of atrial contraction on left ventricular function in six patients with varying degrees of mitral stenosis was determined by utilizing the pressure gradient technique to measure instantaneous aortic blood flow and pressure. Aortic flow was measured as ventricular rate was controlled by right ventricular pacing to create A-V (atrioventricular)(More)
A test of the anticancer effects of dietary fiber was conducted using the N-nitrosomethylurea (NMU)-induced rat mammary tumor model. Starting 3 days after NMU treatment, four different groups of F344 rats (30 rats in each group) were fed as follows: Group 1 received a high-fat diet; group 2, a high-fat plus fiber diet (soft white wheat bran, 10% wt/wt);(More)
Alterations of estrogen-inducible hepatic proteins and estrogen receptor proteins were studied in female rats after daily oral administration of vehicle control (0.5% carboxymethylcellulose), the nonsteroidal antiestrogens tamoxifen (TAM; 3, 11, or 45 mg/kg body weight), toremifene (TOR; 3, 12, or 48 mg/kg body weight), or the potent synthetic estrogen(More)
We previously reported that supplementary dietary wheat bran significantly reduced the incidence of N-nitrosomethylurea (NMU) induced mammary tumors in rats fed a high fat (HF) diet and reduced to a lesser extent the incidence in rats fed a low fat (LF) diet compared to their unsupplemented controls. Using the same cohort of experimental animals, we here(More)
