While the isothermal omega-assisted mechanism of homogeneously distributed fine scale alpha precipitation has been well-documented in several titanium alloys, including Ti-19at%V (Ti-20wt%V), this paper reports that a similar type may occur absence any direct or indirect influence omega precipitates. Rapid heating beta solution-treated and quenched Ti-19at.%V alloy to 500 °C results destabiliza...

Endogenous nucleotides with extracellular functions may be involved in the complex neural control of human urinary bladder (HUB). Using HPLC techniques with fluorescence detection, we observed that in addition to ATP and its metabolites ADP, AMP and adenosine, electrical field stimulation (EFS; 4-16 Hz, 0.1 ms, 15 V, 60 s) of HUB detrusor smooth muscle coreleases novel nucleotide factors, which...

CONTEXT Increased dietary intake of marine omega-3 fatty acids is associated with prolonged survival in patients with coronary heart disease. However, the mechanisms underlying this protective effect are poorly understood. OBJECTIVE To investigate the association of omega-3 fatty acid blood levels with temporal changes in telomere length, an emerging marker of biological age. DESIGN, SETTIN...

Half a century has passed since the hydrogen-bonded secondary structures of polypeptides and proteins were first recognized. An extraordinary wealth of conformational information is now available on peptides and proteins, which are formed of alpha-amino acid residues. More recently, the discovery of well-folded structures in oligopeptides containing beta-amino acids has focused a great deal of ...

BACKGROUND The benefits of antiretroviral therapy for HIV-infected subjects have been limited by an increased risk of metabolic and cardiovascular diseases. The objective of this study was to assess the effects of a low dose of marine omega-3 fatty acids on inflammatory marker concentrations in HIV-infected subjects under antiretroviral therapy (ART). METHODS This was a randomized, parallel, ...

Here, we study the Fučik spectrum for $ p, q $-Laplacian$ -\Delta_p u-\Delta_q u = \alpha \left((u^+)^{p-1}+(u^+)^{q-1}\right)-\beta \left((u^-)^{p-1}+(u^-)^{q-1}\right) $in a bounded domain \Omega in \mathbb{R}^N ($ N\geq1 $), with Dirichlet boundary condition and 1<q<p<\infty $.

We have used ab initio quantum chemical techniques to compute the (13)C(alpha) and (13)C(beta) shielding surfaces for the 14 amino acids not previously investigated (R. H. Havlin et al., J. Am. Chem. Soc. 1997, 119, 11951-11958) in their most popular conformations. The spans (Omega = sigma(33) - sigma(11)) of all the tensors reported here are large ( approximately 34 ppm) and there are only ver...

Nonlinear electrodynamics, which acts as a source of gravity Einstein field equations, leads to emergent cosmology, an alternative solution can avoid Big Bang singularity. In this paper, we explore the emerging universe in models non-linear electrodynamics (described by dimensional parameter $\beta$) using equation state $\omega$ and see how $\beta$ helps cause transition from quasi-static Mink...
