Study of Singlet Oxygen Equilibrium in Dioctadecyldimethylammonium Chloride Vesicles Employing 2-(n-(N,N,N-trimethylamine)-n-alkyl)- 5-alkylfuryl Halides
(2007)
Steady state photolysis and time resolved near infrared
luminescence detection were employed to study the reaction
kinetics of singlet oxygen with three different lipid-soluble
probes incorporated in large unilamellar ...
Design of chitosan nanocapsules with Compritol 888 ATO® for imiquimod transdermal administration. Evaluation of their skin absorption by Raman Microscopy
(Springer, 2020)
Purpose Design imiquimod-loaded chitosan nanocapsules for transdermal delivery and evaluate the depth of imiquimod transdermal absorption as well as the kinetics of this absorption using Raman Microscopy, an innovative ...
Comparative studies on glucose phosphorylating isoenzymes of vertebrates. Identification and characterization of amphibian liver hexokinases
(1978)
Glucose phosphorylating activities were measured in liver extracts from two urodeles and twenty-six anurans. Fractionation on diethylaminoethyl-cellulose columns of liver extracts from these amphibians permitted the ...
Differentially poised vesicles underlie fast and slow components of release at single synapses
(Rockefeller University Press, 2020)
In several types of central mammalian synapses, sustained presynaptic stimulation leads to a sequence of two components of synaptic vesicle release, reflecting the consecutive contributions of a fast-releasing pool (FRP) ...
Differences in nucleotide-binding site of isoapyrases deduced from tryptophan fluorescence
(PERGAMON-ELSEVIER SCIENCE LTD, 2003-05)
Comparative studies of intrinsic and extrinsic fluorescence of apyrases purified from two potato tuber varieties (Pimpernel and Desiree) were performed to determine differences in the microenvironment of the nucleotide ...
Retrosynthesis of CaCO3 via amorphous precursor particles using gastroliths of the Red Claw lobster (Cherax quadricarinatus)
(Elsevier, 2017)
Gastroliths are highly calcified structures formed in the cardiac stomach wall of crustaceans for the temporary storage of amorphous CaCO3 (ACC). The gastrolithic ACC is stabilized by the presence of biomolecules, and ...
An Evolutionary Marker of the Ribokinase Superfamily Is Responsible for Zinc-Mediated Regulation of Human Pyridoxal Kinase
(MDPI, 2020)
The ribokinase superfamily catalyzes the phosphorylation of a vast diversity of substrates, and its members are characterized by the conservation of a common structural fold along with highly conserved sequence motifs ...
Mechanism study of the thiol-addition reaction to benzothiazole derivative for sensing endogenous thiols
(Elsevier, 2015)
We kinetically studied the reaction between endogenous thiols such as -c-glutamylcysteine (c-Glu-Cys),
cysteine (Cys), glutathione (GSH), homocysteine (Hcy), cysteinylglycine (Cys-Gly), and dihydrolipoic acid
(DHLA)- ...
Integrating stress signals at the endoplasmic reticulum: The BCL-2 protein family rheostat
(Elsevier, 2011-04)
The assembling of distinct signaling protein complexes at the endoplasmic reticulum (ER) membrane controls several stress responses related to calcium homeostasis. autophagy, ER morphogenesis and protein folding. Diverse ...
NF-κB activation by depolarization of skeletal muscle cells depends on ryanodine and IP3 receptor-mediated calcium signals
(2007)
Depolarization of skeletal muscle cells by either high external K + or repetitive extracellular field potential pulses induces calcium release from internal stores. The two components of this release are mediated by either ...
