Isolation of plasma membrane fragments and vesicles from ascites fluid of lymphoma-bearing mice and their possible role in the escape mechanism of tumors from host immune rejection

Plasma membranes, generated in vivo by actively growing YAC lymphoma cells, were isolated from cell-free ascites fluid of lymphoma-bearing mice. Partial purification of the ascites fluid (AF) by means of ultra...

Insulin stimulation of glucose and amino acid transport in mouse fibroblasts with elevated membrane microviscosity

Basal and insulin-stimulated transport of 2-deoxy glucose and of α-aminoisobutyric acid in mouse 3T3 fibroblasts were modulated by increasing the lipid microviscosity of the cell plasma membrane. The kinetics ...

Instability of leukocyte aggregation: Lack of evidence for leukoembolization during various states of inflammation

This study centers on the question of whether the phenomenon of leukocyte aggregation, which is typical to inflammatory conditions, is pathogenic per se. We examined patients and laboratory animals in whom the...

Effect of abscisic acid on the photosynthetic oxygen evolution in barley chloroplasts

In vivo effect of abscisic acid (ABA) on photosynthetic oxygen evolution was investigated in barley chloroplasts. The most important kinetic parameters of O₂-producing reactions were changed. The results show inh...

Comparison of the sulfurization of CoMoK/Al₂O₃ catalyst with H₂S and CS₂

Only H₂S consumption and H₂O formation was found in the sulfurization of CoMoK/Al₂O₃ water gas shift catalyst with H₂S/H₂, but CO₂ was formed first, then CH₄, H₂O and H₂S appeared in the later part of TPS with CS

Activation of p53 transcriptional activity by 1,10-phenanthroline, a metal chelator and redox sensitive compound

p53, a tumor suppressor gene, functioning as a transcription factor, has been recently shown in a cell free system to be subject to redox (reduction/oxidation) regulation. Oxidants or metal chelating reagents ...
