Decades of mining activity have resulted in the accumulation significant amounts tailings that are deposited over natural vegetation, forming deposits tens meters thick. The poor organic matter and macronutrients contain a high concentration potentially toxic elements (PTE). Their surface remains unvegetated for long periods time is susceptible to fluvial wind erosion. Equisetum arvense E. telm...

In meiosis, pairing and recombination of homologous chromosomes are crucial for the correct segregation of chromosomes, and substantial movements of chromosomes are required to achieve homolog pairing. During this process, it is known that telomeres cluster to form a bouquet arrangement of chromosomes. The fission yeast Schizosaccharomyces pombe provides a striking example of bouquet formation,...

The effects of dietary field horsetail (Equisetum arvense L.) powder on lipid components were studied in rats fed a 20% casein diet with or without cholesterol (0.5% cholesterol and 0.15% sodium cholate) for 14 days. The ingestion of 0.4% or 4% Equisetum arvense L. powder did not influence food intake or growth. However, a cholesterol diet with Equisetum arvense L. at 4% caused dermatitis at th...

In this paper, the study of antioxidant activity and phenolic composition of three different extracts (EtOAc, n-BuOH and H(2)O) of field horsetail (Equisetum arvense L.) is presented. The antioxidant activity has been evaluated measuring the total reducing power (expressed by Ascorbate Equivalent Antioxidant Capacity - AEAC), inhibition of lipid peroxidation, and free radical scavenging capacit...

Introduction. Human peripheral blood mononuclear cells (PBMCs) are a pool of immune and they also convenient model system for studying pathologies. Aim. Testing bioactivity glycerolipid prepa­rations from fern horsetail species containing long chain polyunsaturated fatty acids (LCPUFAs) towards PBMCs without exogenous stimulation after phorbol-12-myristate-13-acetate (PMA) plus ionomycin stimul...

This study combines multiscale analyses of geological, fault, fracture, and stable isotope data to investigate strike-slip deformation channeling hydrothermal fluids along the Cafarnaum fault calcite veins at different distances from which is a structure in São Francisco Craton, northeastern Brazil. Meteoric with δD values near −45‰ δ18O −6.5‰ temperatures 40–70 °C precipitated as host carbonat...

Sandwich tube structures bio-mimicking horsetail and human tendons offered significant improvement over traditional single multi-cell tubular energy absorbers. The present research aims to investigate three manufactured hybrid aluminum GFRP sandwich tubes subjected quasi-static low-velocity axial compression. crashworthiness characteristics crushing failure mechanisms of are discussed compared ...
