objective(s):to optimize the extraction method using response surface methodology, extract the phenolic compounds, and identify the antioxidant and biological properties of stachys parviflora l. extracts. materials and methods: maceration and ultrasound-assisted extraction (uae) (4, 7, 10 min treatment time, 40, 70, 100 % high-intensity and 60, 80, 100 % (v v-1) methanol purity) were applied t...
BACKGROUND AND OBJECTIVES The Fracture Risk Assessment Tool (FRAX) is widely used to predict the 10-year probability of fracture; however, the clinical utility of FRAX in CKD is unknown. This study assessed the predictive ability of FRAX in individuals with reduced kidney function compared with individuals with normal kidney function. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The discrimi...
We inoculated 5 cm2 of clean chick pads, 5 g of clean pine shavings, and fresh unsanitized broiler breeder eggshell halves with a cell suspension of Campylobacter jejuni in physiological saline. Inoculation levels were 10(2), 10(3), or 10(4) cells per sample. The samples were allowed to remain at room temperature for 15, 30, or 60 min before addition of enrichment broth. When chick pad samples ...
Paleogeographic maps are essential tools for understanding Earth system dynamics. They provide boundary conditions climate and geodynamic modelling, analysing surface processes biotic interactions. However, the temporal spatial distribution of key features such as seaways mountain belts that govern changes interchange differ between various paleogeographies require regular updates with new data...
A bacteriophage (Tphi3) which infects the thermophilic bacterium Bacillus stearothermophilus ATCC 8005 was isolated and characterized. Infection of the bacterium by the bacteriophage was carried out at 60 C, the optimal growth temperature of the host. At 60 C, the phage had a latent period of 18 min and a burst size of about 200. The phage was comparatively thermostable in broth. The halflife o...
Background About 40 to 60% of all patients admitted to pediatric intensive care unitsundergo mechanical ventilation and 10 to 20% will fail to be extubated. We aimed to determine the role of the rapid shallow breathing index (RSBI) in predicting successful weaning of pediatric patients with respiratory failure. Materials and Methods: This cross-sectional study, was performed on 72 mechanical...
