Free arginine (Arg) content was observed to multiply when the level of nitrogen (N) nutrition high, and additional fertilization with boron (B) potentiated this effect. Owing feature, conifers can be suggested for use as bioproducers Arg. Concentrations Arg in relation N B needed better understood. The effect soil on accumulation these elements free one-year-old needles 16-year-old Scots pine (...

The relationship between the L-Arg-NO pathway and tumor growth has not yet been clearly elucidated. The aim of this study was to explore the effects of L-arginine (L-Arg) on cell proliferation, inducible nitric oxide synthase (iNOS) expression and the cell cycle in the human colon carcinoma cell line LS174. LS174 cells were cultured with L-Arg at different concentrations for different times. Th...

A fast, label-free, and multiplexed method based on piezoresistive cantilevers is reported for the detection of specific protein conformations at the nanoscale level. The ligand-binding domain of the human oestrogen receptor (ERalpha-LBD) is used as the experimental model system, and ERalpha-LBD with or without oestradiol (E2) is detected using the conformation-specific peptides alpha/betaI (Se...

a functional treatment for skeletal damages in orthopedic and oral maxillofacial surgeries is required. platelet growth factors such as platelet derived growth factor (pdgf), bone morphogenic factor (bmp), transferring growth factor-β (tgf-β) and insulin-like growth factor-1 (igf-1) proceed wound healing and bone regeneration. in the present study we focused on the effect of platelet rich plasm...

In this study, the two eco-friendly flame retardants of polymeric type (PA-PEI) and monomeric (PA-Arg) phytate amine complexes were prepared via ionic reaction polyethylenimine (PEI) or arginine (Arg), respectively, with phytic acid in an aqueous solution. The chemical structure thermal stability PA-PEI PA-Arg characterized by Fourier-transform infrared spectroscopy (FTIR) thermogravimetric ana...

background: identifying new ways to decrease adiposity have great importance for human health. we aimed to find out whether l – arginine (arg) and selenium alone or together can increase the effect of hypocaloric diet enriched in legumes (hdel) on anthropometric measures in healthy women with central obesity. methods: this randomized, double-blind, placebo-controlled trial was undertaken in 84 ...

To explain the role of the Thr5 residue of proctolin (Arg-Tyr-Leu-Pro-Thr) in the myotropic activity of this insect neuropeptide, we synthesized two groups of its analogues: 1) Arg-Tyr-Leu-Pro-X-OH with X = Val (1), D-Val (2), Ile (3), D-Ile (4), Ala (5), D-Ala (6), Asn (7), Gln (8), Ser (9), Pro (10), Phe (11), Asp (12), Glu (13), Arg (14), D-Arg (15), Lys (16) and Gly (17) and 2) Arg-Tyr-Leu-...
