Localization of a 64-kDa phosphoprotein in the lumen between the outer and inner envelopes of pea chloroplasts [PDF]

open access: yes, 1987
The identification and localization of a marker protein for the intermembrane space between the outer and inner chloroplast envelopes is described. This 64-kDa protein is very rapidly labeled by [γ-32P]ATP at very low (30 nM) ATP concentrations and the ...

Phosphoproteins associated with cyclic nucleotide stimulation of ciliary motility in Paramecium [PDF]

open access: yes, 1990
Permeabilized, MgATP-reactivated cells of Paramecium (models) respond to cyclic AMP and cyclic GMP by increasing forward swimming speed. In association with the motile response, cyclic AMP and 8-bromo-cyclic GMP (8-Br-cyclic GMP) stimulated protein ...

Immunocytochemical localization of chromatin regions UV-microirradiated in S phase or anaphase : Evidence for a territorial organization of chromosomes during cell cycle of cultured Chinese hamster cells [PDF]

open access: yes, 1983
Chinese hamster cells (M3-1 line) in S phase were laser-UV-microirradiated (λ, 257 nm) at a small site of the nucleus. Cells were fixed either immediately thereafter or in subsequent stages of the cell cycle, including prophase and metaphase.

Cooperation of Gq, Gi, and G12/13 in Protein Kinase D Activation and Phosphorylation Induced by Lysophosphatidic Acid [PDF]

open access: yes, 2003
To examine the contribution of different G-protein pathways to lysophosphatidic acid (LPA)-induced protein kinase D (PKD) activation, we tested the effect of LPA on PKD activity in murine embryonic cell lines deficient in Galpha q/11 (Galpha q/11 KO ...

EFFECTS OF INSULIN, GLUCAGON, AND INSULIN/GLUCAGON INFUSIONS ON LIVER MORPHOLOGY AND CELL DIVISION AFTER COMPLETE PORTACAVAL SHUNT IN DOGS [PDF]

open access: yes, 1976
Insulin, glucagon, and insulin/glucagon mixtures have been infused for four days into the left portal vein of dogs after portacaval shunt. In the left but not the right liver lobes, insulin alone reduced atrophy, preserved hepatocyte ultrastructure, and ...

Improved detection of molecular markers of atherosclerotic plaques using sub-millimeter PET imaging [PDF]

open access: yes, 2020
Since atherosclerotic plaques are small and sparse, their non-invasive detection via PET imaging requires both highly specific radiotracers as well as imaging systems with high sensitivity and resolution.

Nerve commitment in Hydra. II. Localization of commitment in S phase [PDF]

open access: yes, 1981
The kinetics of nerve differentiation were investigated during head regeneration in Hydra. In particular the cell cycle parameters of stem cells undergoing nerve commitment were determined.

UV micro-irradiation of the Chinese hamster cell nucleus and caffeine post-treatment immunocytochemical localization of DNA photolesions in cells with partial and generalized chromosome shattering [PDF]

open access: yes, 1983
UV micro-irradiation of a small part of the Chinese hamster nucleus and caffeine post-incubation often results in shattered chromosomes at the first post-irradiation mitosis.

Rapid synthesis and turnover of brain microsomal ether phospholipids in the adult rat

open access: yesJournal of Lipid Research, 2002
The rates of synthesis, turnover, and half-lives were determined for brain microsomal ether phospholipids in the awake adult unanesthetized rat. A multicompartmental kinetic model of phospholipid metabolism, based on known pathways of synthesis, was ...

Determination of the phloem transport pathways and destination of photosynthates in soybean using autoradiography and fluorescent tracer imaging

open access: yesPlant Signaling & Behavior
Vascular tissues transport water and nutrients in plants, with the phloem distributing photosynthates from source to sink. The direction of phloem transport is determined by the positional relationship between sources and sinks and by vascular ...
