Inhibition by spermine of the inner membrane permeability transition of isolated rat heart mitochondria

FEBS Letters, 1992
The effect of spermine on the permeability transition of the inner mitochondrial membrane of isolated rat heart mitochondria was evaluated. The permeability transition was triggered using a series of agents (t-butyl hydroperoxide, phenylarsine oxide ...

Calculation of inner-shell transitions in

Journal of Physics B: Atomic, Molecular and Optical Physics, 1996
We have undertaken extensive configuration interaction calculations to determine the positions of 3p-hole states of of the form ; ; . Comparison is made with the 3p photoabsorption spectrum measured by Costello et al (1991 Phys. Rev. A 43 1441) with a dual-laser - plasma technique.

Atomic inner-shell transitions

Journal of the Optical Society of America B, 1984
Atomic inner-shell processes have quite different characteristics, in several important aspects, from processes in the optical regime. Energies are large, e.g., the 1s binding energy reaches 100 keV at Z = 87; relativistic and quantum-electrodynamic effects therefore are strong.

Calculations of inner shell transitions in Ca+

Journal of Electron Spectroscopy and Related Phenomena, 1996
Abstract We discuss the calculation of inner-shell transitions in the iron group elements in general and present calculations of transitions involving the excitation of a 3p electron from the metastable 3p 6 3d state in the Ca + ion.

Inner shell transitions in heavy atoms

Physica Scripta, 1993
Inner shell transitions in medium to very heavy atoms are treated within a relativistic framework. The many-body part of the calculation includes full relaxation, correlation and the admixture of, sometimes degenerate, states with two vacancies and one excited particle.

The Na+/H+ exchanger in transitional cells of the inner ear

Hearing Research, 1993
The cytosolic pH (pHi) of transitional cells from the ampulla of the gerbil was measured micro-fluorometrically with the pH-sensitive dye 2',7'-bicarboxyethyl-5(6)-carboxyfluorescein (BCECF) to assess the possible contribution of a Na+/H+ exchanger to the regulation of pHi. All experiments were conducted in virtually HCO3(-)-free solutions.

Imipramine and lipid phase transition in inner mitochondrial membrane

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1980
As ascertained by freeze-fracture electron microscopy, imipramine prevents lateral phase separation from taking place in inner mitochondrial membranes at sub-zero temperatures. Electron spin resonance (ESR) measurements performed on mitochondrial membranes labeled with the N-oxyl-4',4'-dimethyloxazolidine derivative of 16-ketostearic acid, show that ...

Temperature in transition region and inner corona

Astrophysics and Space Science, 1983
The investigation of Alamet al. (1979), of the temperature distribution in spherically-symmetric transition region and inner corona, appears to be in error.

Temperature distribution in the transition region and inner corona

Solar Physics, 1979
The energy balance equation for a general solar atmosphere without assuming the plane-parallel approximation is solved analytically. This leads to models for both the transition region and inner corona as well as for the outer corona. The form of the latter is very similar to that of the hydrostatic conduction model of Chapman (1957).

A heating model for the transition zone and inner corona

Solar Physics, 1984
This paper studies the temperature and density distributions of the transition zone and inner corona in two cases: (1) the action of mechanical waves (e.g. Alfven waves) in a self-consistent theoretical model; (2) the solution of the energy equilibrium equation by assuming that the upper corona is heated by mechanical wave energy; but the lower part is
