AIM To evaluate total body bone mineral density and regional bone mineral density in patients with prostate cancer with and without metastases, and to correlate them with bone scintigraphy findings. PATIENTS AND METHODS 135 patients with prostatic carcinoma and 50 healthy subjects were investigated with bone scintigraphy and dual-energy X-ray absorptiometry. The bone scintigraphic findings we...

Results The C : N ratio in plant tissue, litter, forest floor and mineral soil exhibited large variation across various sequences, with an average of 145.8 9.4 (mean SE), 49.9 3.0, 38.2 3.1 and 18.5 0.9, respectively. In most sequences, the plant tissue C : N ratio increased significantly with stand age, while the C : N ratio in litter, forest floor and mineral soil remained relatively constant...

This paper presents the effect of soil supplementation with urea and magnesium on nitrogen uptake and its utilization by two different types of hybrid maize cultivars. Based on the results of 3-year fertilization studies, it was shown that for average volume of grain yield of maize, nitrogen content in grain dry matter and nitrogen uptake with its yield was significantly determined by the doses...

Ectomycorrhizal fungi allow their host plants access to organic forms of N through enzymatic mineralization of the substrate and enhanced absorption of amino acids and mineral N. The cost to the plant is carbohydrates that support fungal growth and metabolism. Enrichment of soils with mineral N, as through atmospheric deposition, may affect the growth and function of these fungi by direct effec...

Effects of bio-nitrogen fertilizer (bio-N), as a partial alternative to mineral-nitrogen fertilizer (mineral-N), on growth, yield and yield quality of broccoli plants were investigated. Bio-N was applied at 1, 2 or 3 doses in combination with 65% of the recommended dose of mineral-N (bio-N1, bio-N2 or bio-N3 + 2⁄3mineral-N). However, 100% of the recommended dose of mineralN was applied as a con...

background and objectives: availability and uptake of mineral by explants are recognized as being important in tissue culture. the limiting factor for maximum mineral uptake and optimum growth is that minerals are not enough available to the explants. there are the inter-relationships between plant growth, mineral uptake, medium water potential, and mineral movement through the medium. plantlet...

Net N mineralization rate (NMR), net N consumption rate (NCR), microbial biomass carbon (MBC) and nitrogen (MBN), potentially mineralizable N (PMN) and mineral N (N-NH4 + and N-NO3 –) were measured in paddy soil at five growth stages of rice to determine the effect of long-term fertilization in subtropical China. The studied long-term treatments included CK (no fertilization), N, NP, NPK and NP...

background: increased requirement and decreased dietary intakes of micronutrients during pregnancy might affect maternal health and pregnancy outcomes. this study was aimed to examine the effects of two types of multiple micronutrient supplementations on pregnancy outcomes in kashan, iran. methods: in a randomized single‑blind controlled clinical trial, 104 primigravid singleton pregnant women ...
