The MeOH extract of the leaves of rosemary (Rosmarinus officinalis L.) completely inhibited the motility of cultured epimastigotes of Trypanosoma cruzi at the concentration of 2 mg/ml after 2 h of incubation. Activity-guided fractionation of the MeOH extract has resulted in the isolation of three triterpene acids, betulinic, oleanolic and ursolic acids. Ursolic acid stopped the movement of all ...

Sodium polyanethol sulfonate (SPS) at 500 microgram/ml, but not sodium amylosulfate (SAS) at 500 microgram/ml, precipitated egg white lysozyme (1 mg and 50 microgram of lysozyme per ml) as determined with the assay strain Micrococcus lysodeikticus ATCC 4698. Fresh and heat-inactivated (56 degrees C, 30 min) human serum (80%, vol/vol) killed M. lysodeikticus (10(4) bacteria per ml at zero time) ...

Ninety-nine clinical staphylococcal isolates (58 coagulase-negative Staphylococcus spp. [CoNS] and 41 Staphylococcus aureus isolates) were evaluated for susceptibility to oxacillin. The following susceptibility testing methods, media, and incubation conditions were studied: agar dilution by using Mueller-Hinton (MH) medium (Difco) supplemented with either 0, 2, or 4% NaCl and incubation at 30 o...

Results: Overall agreement rates within ±1 dilution between the 2 methods were 86.7% (24 h) and 94.1% (48 h) for amphotericin B, and 85.5% (24 h) and 73.3% (48 h) for fluconazole. All C. albicans, C. pelliculosa, C. glabrata, and C. kefyr isolates were inhibited by ≤1 μg mL−1 of amphotericin B, and fluconazole resistance was not observed in C. albicans or C. tropicalis isolates according to the...

The influence of soaking and germination on the physicochemical characteristics tigernut tubers (Cyperus esculentus L.) are investigated. Tubers (Ø > 1 cm) were soaked in an ascorbic acid solution (0.1%) for 48 h at 40 °C before undergoing 6 days. textural profile, capacity energy biochemical composition these determined. varied from 76.18 to 79.48% quantities 24 mL, respectively. profile de...

in this study, the effect of several species of fermenting yeast and fermentation conditions (periodic aeration and temperature) on quality parameters of non-alcoholic beer is assessed. yeast starters with different inoculation percent were added separately into wort with determined gravity. wort was fermented for 48 h in different temperatures under aerobic condition or periodic aeration (ever...

M e t h o d s Design: Randomized controlled trial. Allocation: Concealed.* Blinding: Blinded (outcome assessors).* Follow-up period: Up to 90 days. Setting: 21 intensive care units (ICUs) in university or community hospitals in France. Patients: 360 patients (mean age 65 y, 73% men) who had ARF, the multiple-organ dysfunction syndrome, and need for renalreplacement therapy. Exclusion criteria i...

Abstract The application of aluminum alloys at elevated temperatures has been attractive for decades, and Al-Ni-based have recently recognized as potential candidates. effect Mn on Al-4Ni alloy investigated in this work. Addition transformed the eutectics from Al 3 Ni/α-Al to 9 (Ni,Mn) 2 /α-Al phases. also improved tensile strength both 25°C 250°C. yield increased 48 MPa 92 with 1.87% then 117 ...

Studies were conducted to determine whether intestinal cellulolytic bacteria could be introduced into the bovine rumen or pig large intestine. In the first study, the ruminal fluid of three cows was evacuated and replaced with 20 liters of buffer and 6 liters of the ruminal or swine cellulolytic organism Clostridium longisporum or Clostridium herbivorans, respectively. The introduced organisms ...
