Platelet-Rich Plasma (PRP) is a low-cost procedure to deliver high concentrations of autologous growth factors (GFs). Platelet activation is a crucial step that might influence the availability of bioactive molecules and therefore tissue healing. Activation of PRP from ten voluntary healthy males was performed by adding 10% of CaCl2, 10% of autologous thrombin, 10% of a mixture of CaCl2 + throm...

This comparative study was aimed at estimating analytical behavior of methods for determination plant available potassium applied to Bulgarian arable soils and reveal the relationship between amount extractable K. Twenty-four samples from two traditional agricultural regions in Bulgaria were studied. Soil extracted by NH4OAc/HOAc pH 4.5 (AA), diluted double acid (Mehlich 1), CaCl2, BaCl2 a modi...

Cyclic-ADP-ribose (cADPR) has been reported to serve as a second messenger to mobilize intracellular Ca2+ independent of IP3 in a variety of mammalian cells. This cADPR-mediated Ca2+ signaling pathway importantly participates in the regulation of various cell functions. The present study determined the role of endogenous cADPR in mediating ryanodine-sensitive Ca2+-induced Ca2+ release (CICR) in...

The group 2 metal halides and corresponding metal halide hydrates serve as useful model systems for understanding the relationship between the electric field gradient (EFG) and chemical shift (CS) tensors at the halogen nuclei and the local molecular and electronic structure. Here, we present a 35/37Cl and 43Ca solid-state nuclear magnetic resonance (SSNMR) study of CaCl2. The 35Cl nuclear quad...

Natural Zn reserves might be exhausted in the following decades. Electric arc furnace (EAF) dust is an essential secondary resource. The recovery of from EAF a critical factor sustainable development industry and steelmaking industry. Efficient destruction ZnFe2O4 crystal structure separation Fe are key issues to recycle dust. Molten metal chlorides believed effective breaking ZnFe2O4. This wor...

Sorption-based thermal storage has drawn considerable attention for sustainable and cost-effective management energy storage. However, the low sorption capacity of sorbents is a long-standing challenge achieving high-energy-density sorption-based Herein, we demonstrate an ultrahigh-energy/power-density battery (STB) enabled by graphene aerogel (GA)-based composite efficient harvesting with reco...

‘Golden Delicious’ apples (Malus /domestica Borkh.) were either untreated or pressure-infiltrated after harvest with 0, 1, 2, 3 or 4% CaCl2 solutions (w/v) and stored at 0 8C for up to 6 months. The chemical composition of the fruit cortical tissue and cell walls of the 2 /4 mm layer under the epidermis was studied. Storage of untreated fruit resulted in a decrease in K, P, Mg, S and Suc conten...

The objective of the study was to determine changes in activities enzymes degrading cell wall response hot water, calcium chloride (CaCl2) and 1-methlylcyclopropene (1-MCP) treatments during post-harvest storage sweet cherries. For this purpose, 0.5, 1, 5 μl L-1 1-MCP, 1% 2% CaCl2 45, 50, 55 oC waters were applied As a result conducted with wall, it observed that very significant increases occu...

Perfusion of the isolated rat heart with Ca2+ concentrations exceeding 3 mM activated phosphofructokinase and phosphorylase, and decreased the concentration of cyclic AMP. Half-maximal activation of phosphofructokinase occurred at 5 mM-CaCl2; significant activation of phosphorylase did not occur until the concentration of CaCl2 exceeded 12 mM. The time course for the activation of phosphofructo...

The objective of this study was to evaluate the sealing ability and antibacterial activity of Ca3SiO5/CaCl2 composite cement. Fifty maxillary anterior teeth were instrumented according to step-back technique and filled with experimental and control materials. To evaluate the sealing ability, a fluid transport model using glucose was employed for quantitative analysis of endodontic microleakage....
