Phytocompounds of natural origin are not only a potential source for maintaining human health but also the supplement nutrients long period survival. In recent years, essential oils and herbal extracts have attracted great scientific interest due to its as antioxidants biologically active compounds, especially in last decade with more intensive studies chemotherapies antioxidant activity. The m...

In this paper, according to G-Brownian motion and other related concepts properties, we define multiple Itô integrals driven by G-Lévy process. By using the G-Itô formula properties of G-expectation, two main theorems about integral are obtained proved. These provide powerful help for subsequent research on jump

Abstract. We investigate the impact of so-called energetic particle precipitation (EPP) indirect effect on lower stratospheric ozone, ClO, and ClONO2 in Antarctic springtime. use observations from Microwave Limb Sounder (MLS) Ozone Monitoring Instrument (OMI) Aura, Atmospheric Chemistry Experiment – Fourier Transform Spectrometer (ACE-FTS) SCISAT, Michelson Interferometer for Passive Sounding (...

This research aims to make a parallel and determine the symmetry between main male characters of Shakespearian play “The tragedy Hamlet, Prince Denmark”. For this purpose, each important character is analysed in-depth with use primary text other critical views. The approach used in paper was based on source, by employment quotes lines, verses how they manage be interpreted regarding portrayal c...

Abstract. In this study we report the synthesis of single crystals burbankite, Na3Ca2La(CO3)5, at 5 GPa and 1073 K. The structural evolution, bulk modulus thermal expansion burbankite were studied determined by two separate high-pressure (0–7.07(5) GPa) high-temperature (298–746 K) in situ single-crystal X-ray diffraction experiments. refined parameters a second-order Birch–Murnaghan equation s...

The 3',5'-cAMP-adenosine pathway (3',5'-cAMP→5'-AMP→adenosine) and the 2',3'-cAMP-adenosine pathway (2',3'-cAMP→2'-AMP/3'-AMP→adenosine) are active in the brain. Oligodendrocytes participate in the brain 2',3'-cAMP-adenosine pathway via their robust expression of 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNPase; converts 2',3'-cAMP to 2'-AMP). Because Schwann cells also express CNPase, it i...

AMP-activated protein kinase (AMPK) acts as a cellular energy sensor: it responds to an increase in AMP concentration ([AMP]) or the AMP-to-ATP ratio (AMP/ATP). Metformin and phenformin, which are biguanides, have been reported to increase AMPK activity without increasing AMP/ATP. This study tests the hypothesis that these biguanides increase AMPK activity in the heart by increasing cytosolic [...

The photoaffinity analog 2-azido-AMP was found to be a potent allosteric inhibitor of pig kidney fructose 1,6-bisphosphatase. UV-induced covalent incorporation of 2-azido-[8-3H]AMP fully inactivated the enzyme at a level stoichiometric with its subunit composition (4 mol of analog/mol of tetramer). The photoincorporation and inactivation were prevented by the presence of AMP but not by the subs...

Abstract. Chemical ionisation mass spectrometry (CIMS) using I− (the iodide anion), hereafter I-CIMS, as a primary reactant ion has previously been used to measure NO3 and N2O5 both in laboratory field experiments. We show that reports of large daytime mixing ratios (both usually present detectable amounts only at night) are likely be heavily biased by the ubiquitous presence HNO3 troposphere l...

This paper concerns the calculation of equilibrium composition plasma mixture Air Fe2O3, SiO2, Al2O3 and CO in temperatures range 1000 K to 6000 K. We supposed that is at atmospheric pressure local thermodynamic (ETL). In Saharan zone, aerosols are proven from desert dust biomass fires. They essentially composed oxides silicon, calcium, iron, aluminum carbonaceous elements biomass. Thus, air ci...
