introduction: 18f-choline pet-ct is an increasingly used technique in patients with prostate cancer. the main indication is to localise the disease in patients with biochemical recurrence. to accurately interpret 18f-choline pet, knowledge of normal tracer distribution is paramount. the aim of this study was to describe the normal distribution pattern of 18f-choline by measuring the maximum sta...

background: synthetic dyes have several harmful effects on human health as well as aquatic life. in this study, activated carbon (av-ac), based on aloe vera leaf shells, was used as a novel agricultural adsorbent, one that is low-cost and available for the removal of congo red (cr) as a carcinogenic dye from aqueous solutions. methods: in the batch system, the influence of different parameters ...

OBJECTIVE To develop a physical activity questionnaire aimed at Brazilian adolescents and to assess its validity and reproducibility. METHODS A total of 94 adolescents (30 males and 64 females) aged 11-16 years were included in the study, which was conducted in 2004. The questionnaire comprised 17 questions on habitual physical activity in the last 12 months (15 questions on sports and physic...

plant growth promoting rhizobacteria and arbuscular mycorrhizal fungi can inhanced plant growth by increasing nutrient uptake. in order to investigate the effect of pgpr and amf on some morphological parameters, macro (nitrogen, phosphorus, potassium, calcium and magnesium) and micro (iron, zinc and copper) nutrients uptake, percentage of root colonization and some morphological factors of pepp...

PURPOSE To compare the conspicuity of malignant lesions between FDG PET/CT and a new simultaneous, time-of-flight (TOF) enabled PET/MRI scanner. METHODS All patients underwent a single-injection of FDG, followed by a dual imaging protocol consisting of PET/CT followed by TOF PET/MRI. PET/CT and PET/MRI images were evaluated by two readers independently for areas of FDG uptake compatible with ...

in order to study the effects of simultaneous application of znso4 and biological fertilizer, azotobacter chroococcum and azospirillum brasilense, on grain yield and nitrogen uptake efficiency in rapeseed (brassica napus l.), cv. hyola308, a field experiment was conducted as split plot factorial based on randomized complete block design at research field of faculty of agricultural sciences, uni...

In microbial competition theory, the Michaelis-Menten (MM) half-saturation coefficient is often considered to be a trait of an organism defining competitive strength in a trade-off conflict with maximum uptake rate. Theoretical studies have shown that a quadratic model characterizes the uptake rate, and that this model can be approximated by a MM model. Here, we review recent developments in nu...

the demand for low fat snacks is increasing. there are different methods to produce low fat fried products. one of these methods is coating. in this study effect of carrageenan, oil temperature and frying time, on oil uptake of fried products (chips and strips) has been evaluated. samples were deep fried in frying oil (palm olein) at 160, 175 and 190 ºc. in order to evaluate the effect of fryin...
