We report on the Shubnikov de Haas (SdH) oscillations in quasi two-dimensional molecular conductor $\alpha-$(BETS)$_{2}$I$_{3}$ [BETS: bis(ethylenedithio)tetraselenafulvalene] laminated polyimide films at 1.7 K. From SdH phase factor, we verified experimentally that material is Dirac fermion under pressure. vicinity of transition between strongly correlated insulating and phases, a possible can...
Intercellular adhesion molecule-1 (ICAM-1) is associated with processes of inflammation. We investigated the effects of deoxypodophyllotoxin (DPT) on tumor necrosis factor-alpha (TNF-alpha) induced ICAM-1 expression in the mouse lung epithelial cell line, LA4. DPT (5 to 20 nM) inhibited TNF-alpha-induced ICAM-1 expression through nuclear factor-kappa B (NF-kappaB) in a dose-dependent manner and...
A bifunctional alpha-amylase/subtilisin inhibitor (RASI) was purified to electrophoretic homogeneity from rice (Oryza sativa L.) bran. Its molecular mass was 21 kDa by SDS-PAGE and its isoelectric point was 9.05. Purified RASI inhibited subtilisin Carlsberg strongly and inhibited alpha-amylase from germinating rice seeds weakly. It inhibited rice alpha-amylase more than barley alpha-amylase, an...
External application of alpha-dihydro-grayanotoxin II (alpha-H2-GTX II) to squid giant axon under nonperfused condition caused substantial membrane depolarization. Intracellular perfusion of the fibers retarded this depolarization appreciably. Tritium-labeled alpha-dihydro-grayanotoxin II ([3H]alpha-H2-GTX II) in the external medium can permeate through the cell membrane, but permeation of alph...
A comparison of urinary alpha 1-microglobulin concentrations to the behaviour of other indicators of renal tubular disorders, beta 2-microglobulin, retinol-binding protein and N-acetyl-beta-D-glucosaminidase (NAG) has been made. In acute tubular disorders the concentrations of urinary beta 2M and RBP are highly correlated (r = 0.89) but this is less marked for alpha 1M and beta 2M (r = 0.55) an...
The agonist properties of acetylcholine (ACh), tetramethylammonium, ethyl-trimethylammonium and choline were evaluated for muscle and neuronal nicotinic receptors in Xenopus oocytes. The only essential feature for a neuronal receptor agonist appears to be the charged nitrogen. For specific receptor subtypes, other structural elements appear permissive (neither increasing nor decreasing activity...
