Abstract The symmetrized bidisc $$\begin{aligned} G {\mathop {=}\limits ^\mathrm{{def}}}\{(z+w,zw):|z|&lt;1,\quad |w|&lt;1\}, \end{aligned}$$ G = def { ( z +</m...

The structure of the E. coli beta clamp polymerase processivity factor has been solved in complex with primed DNA. Interestingly, the clamp directly binds the DNA duplex and also forms a crystal contact with the ssDNA template strand, which binds into the protein-binding pocket of the clamp. We demonstrate that these clamp-DNA interactions function in clamp loading, perhaps by inducing the ring...

Propranolol, a non-selective beta blocker, was administered orally in therapeutic doses. The effects of a single dose (160 mg) and one week's treatment (80 mg twice a day) on platelet function were compared in healthy young subjects. There were no significant changes in circulating platelet aggregates, template bleeding time, platelet factor 3 availability and thromboxane beta 2 (TX beta 2) gen...

Accumulation of beta-carotene during postharvest ripening of nine Thai mango cultivars was assessed after verifying extraction and high-performance liquid chromatographic quantification of the beta-carotene stereoisomers for this sample matrix. No relevant trans-cis isomerization was induced by the analytical procedure. The vitamin A potential of mangoes was evaluated at different ripening stag...

the normal carrying angle in shiraz population was measured on the basis of sex and age. the right elbow angle of 4266 cases was examined from birth to 30 years old. this study found the carrying angle in 2540 females to be 7.20 (range 2-19) and in 1726 males to be 6.40 (range 2-11), a 0.80 difference. a significant difference (p= 0.05) was found in relation to age. there is a gradual increase ...

Lorentz violation modifies the dispersion relation of gravitational waves (GWs), and induces birefringence anisotropy in propagation. Our study shows that can also activate multiple polarizations GWs. We use gauge invariants to investigate GWs bumblebee gravity model, obtain following results. (i) For a vector background ${b}^{\ensuremath{\mu}}$ with only nonzero temporal component ${b}^{t}$, t...

Blood flow dynamics under physiologically realistic pulsatile conditions plays an important role in the growth, rupture, and surgical treatment of intracranial aneurysms. The temporal and spatial variations of wall pressure and wall shear stress in the aneurysm are hypothesized to be correlated with its continuous expansion and eventual rupture. In addition, the assessment of the velocity field...
