Fluxes of major bioelements associated with sinking particles were quantified in late summer 2018 as part the EXport Processes Ocean from RemoTe Sensing (EXPORTS) field campaign near Station Papa subarctic northeast Pacific. The thorium-234 method was used conjunction size-fractionated (1–5, 5–51, and >51 μm) concentrations particulate nitrogen (PN), total phosphorus (TPP), biogenic sili...
Abstract A controlled environment and composition of the compost used for commercial production Agaricus bisporus can allow fruiting bodies with increased nutritional value to be obtained. The present study aimed first investigate content bioelements in A. harvested from three flushes cultivation estimate which elements are accumulated most effectively by determination bioconcentration factor (...
We have analyzed concentrations of magnesium (Mg), calcium (Ca), copper (Cu), zinc (Zn) and iron (Fe) in hair of a group of 82 children with mental retardation, in which 9 patients suffered from epilepsy, 18 from the Down's syndrome and 55 from cerebral palsy. Girls comprised little over 50% of the patients. In the group of boys with epilepsy, we found Mg, Ca, Cu and Fe deficiency, and normal l...
Abstract The intention of this chapter is to give insight into the properties and peculiarities stable isotopes bioelements. Following an overview about terminology ʻtechnical jargonʼ used in isotope sciences, methods calculate express isotopic abundances are presented. Subsequently, a short description physicochemical basis equilibrium kinetic (mass-dependent) effects (EIEs KIEs) as origin fra...
INTRODUCTION The dysregulation of pH by cancerous cells of solid tumors is able to create a unique milieu that is in favor of progression, invasion and metastasis as well as chemo-/immuno-resistance traits of solid tumors. Bioelements involved in pH dysregulation provide new set of oncotargets, inhibition of which may result in better clinical outcome. METHODS To study the impacts of pH dysre...
