CHANGE IN BLOOD GELSOLIN CONCENTRATION IN RESPONSE TO PHYSICAL EXERCISE

open access: yesBiology of Sport, 2013
Plasma gelsolin (pGSN) produced by muscle is an abundant protein of extracellular fluids capable of severing actin filaments and eliminating actin from the circulation. Additionally, pGSN modulates the cellular effects of some bioactive lipids.

Climate Change Increases Nitrogen Concentration in Rice With Low Nitrogen Use Efficiency

open access: yesEarth's Future, 2021
Growing evidence indicates that climate change has significant impacts on crop production. However, the spatial variability and extent of the impacts on N concentrations in crops have yet to be explicitly described, although N concentration is a critical

Effect of gadolinium concentration on temperature change under magnetic field.

open access: yesPLoS ONE, 2019
Gadolinium based contrast agents (GBCAs) were found to play a role in nephrogenic systemic fibrosis in patients with and without renal impairment. Therefore, preserving the structural stability of GBCAs to reduce their propensity to liberate Gd3+ is of ...

Changes of Angiogenin Serum Concentrations in the Perinatal Period [PDF]

open access: yesPediatric Research, 1997
The polypeptide angiogenin, a normal constituent of human plasma, might be involved in endothelium homeostasis, angiogenesis, and neovascularization accompanying various diseases. This study aimed at determining angiogenin serum concentrations in the perinatal period of healthy newborns and at forming a baseline for this protein, which in the future ...

Changes of Concentrations of Elements in Deciduous Teeth with Age [PDF]

open access: yesBiological Trace Element Research, 2013
The aim of this study was to describe the issue of changes in the concentration of some elements (Mn, Fe, Mg, Cu, K, Cr, Pb, Cd, and Ca) in the mineral composition of deciduous teeth and to answer the question whether there was a tendency to change the metal concentration, depending on children's age.
