Plasma calcium and calcitonin levels in eels fed a high calcium solution or transferred to seawater.

 · 1970

To examine the physiological role of calcitonin (CT) in calcium homeostasis of teleosts, we compared calcium and CT levels in freshwater eels fed a high calcium-consomme solution (Ca2+: 1.25 M; 1 ml/1…

Magnification--a new look at a long-known optical property of dentin.

 · 1970

Light propagation in human dentin exhibits a strong directional dependence featuring the long-known optical magnification property. We hypothesized that this anisotropic effect is caused by multiple s…

Experimental characterization of magnetically focused electron contamination at the surface of a high-field inline MRI-linac.

 · 1970

PURPOSE: The fringe field of the Australian MRI-linac causes contaminant electrons to be focused along the central axis resulting in a high surface dose. This work aims to characterize this effect usi…

Trace Analysis of Sinomenine Hydrochloride Using CdTe/CdS Quantum Dots-enhanced Chemiluminescence.

 · 1970

A novel flow-injection chemiluminescence (FI-CL) method was described for the determination of sinomenine hydrochloride (SIN). The method was based on the inhibitory effect of SIN on the CL reaction o…

Vesicles in haptotaxis with hydrodynamical dissipation.

 · 1970

We analyze the problem of vesicle migration in haptotaxis (a motion directed by an adhesion gradient), though most of the reasoning applies to chemotaxis as well as to a variety of driving forces. A b…
