Background & Aim: Deep heated oils produce toxins that endanger peoplechr('39')s health. The use of herbal supplements along with exercise can improve general health. Therefore, the present study aimed to investigate the effect of aerobic and octapamine training on HSP70 and Caspase 3 protein in brown adipose tissue of rats received w deep heated oils. Methods: 40 male wistar rats after four w...
Introduction: Deep heated oils produce toxins that endanger people's health. The current study aims to investigate the simultaneous effect of aerobic training and Octopamine consumption on the mitophagy of brown adipose tissue after the induction of intoxication through deeply heated oil in male wistar rats. Method: 40 male wistar rats after four weeks of feedi...
Raman spectroscopy and synchrotron x-ray diffraction measurements of ammonia (NH(3)) in laser-heated diamond anvil cells, at pressures up to 60 GPa and temperatures up to 2500 K, reveal that the melting line exhibits a maximum near 37 GPa and intermolecular proton fluctuations substantially increase in the fluid with pressure. We find that NH(3) is chemically unstable at high pressures, partial...
Partially denatured 16S rRNA from 30S ribosomes shows features of secondary structure in electron microscopy that correspond to the well accepted secondary structure model derived from chemical modification and phylogenetic data. However, a very different conformation is seen in precursor 16S rRNA sequences contained within 30S pre-rRNA transcripts: the major 5'-terminal loop is absent, and sev...
When DNA molecules are heated they denature. This occurs locally so that loops of molten single DNA strands form, connected by intact double-stranded DNA pieces. The properties of this ‘melting’ transition have been intensively investigated. Recently there has been a surge of interest in this question, caused by experiments determining the properties of partially bound DNA confined to nanochann...
Observations on antibody production in the rabbit in response to the injection of the LS antigen of vaccinia have shown that this antigen retains its ability to stimulate the production of L and S antibodies, not only when it is in a state of solution as found in lapine Seitz filtrates, but also after it has been partially purified. As reported in previous papers, both the L and S antibodies pa...
The presence of carbonates in inclusions in diamonds coming from depths exceeding 670 km are obvious evidence that carbonates exist in the Earth's lower mantle. However, their range of stability, crystal structures and the thermodynamic conditions of the decarbonation processes remain poorly constrained. Here we investigate the behaviour of pure iron carbonate at pressures over 100 GPa and temp...
Ribonuclease-A (RNase-A) has been a model for studying protein folding and unfolding. However, we show here that its unfolding at neutral pH is complicated by aggregation. Circular dichroism thermal scans showed that reversibility of RNase-A after heating is only about 63%. In accordance with this observation, native-polyacrylamide gel electrophoresis of the sample heated at 75 degrees C showed...
Massive stars drive powerful, supersonic winds via the radiative momentum associated with the thermal UV emission from their photospheres. Shock phenomena are ubiquitous in these winds, heating them to millions, and sometimes tens of millions, of degrees. The emission line spectra from the shock-heated plasma provide powerful diagnostics of the winds’ physical conditions, which in turn provide ...
We present work on 3D hypersonic laminar flows of air around blunt bodies with applied magnetic fields of various strengths. The air is heated by a shock that can change its thermodynamic properties. We treat the air both as a calorically perfect gas (chemically frozen) and as a real gas in thermodynamic equilibrium. Due to the high temperature the thermodynamic properties of the air are affect...
