Synthesis of metabolism-resistant substrates for the transport system for cationic amino acids; their stimulation of the release of insulin and glucagon, and of the urinary loss of amino acids related to cystinuria
(Elsevier, 1973-04-16)
Several amino acids have been synthesized as model transport substrates building on the piperidine and cyclohexane rings. Only when the distal N atom is part of an unambiguously cationic structure are these compounds ...
Soluble cytochrome b5 from human erythrocytes
(Elsevier, 1972-07-12)
1. A hemeprotein with properties similar to microsomal cytochrome b5 has been detected in the supernatant fraction of hemolysates of human, beef, and rabbit erythrocytes. A method has been developed for determining the ...
Scalable Multiplexed Drugâ Combination Screening Platforms Using 3D Microtumor Model for Precision Medicine
(Springer New YorkWiley Periodicals, Inc., 2018-10)
Cancer heterogeneity is a notorious hallmark of this disease, and it is desirable to tailor effective treatments for each individual patient. Drug combinations have been widely accepted in cancer treatment for better ...
Estimation of adsorbed anion charge density from the electrode charge-potential relationship
(Elsevier, 1967)
A correlation, based upon available data for a number of electrolytes at 0.1 and 1.0 N concentrations, may permit adsorbed anion charge densities to be estimated as a function of electrode potential by comparing the ...
Early events of Bacillus anthracis germination identified by time-course quantitative proteomics
(WILEY-VCH Verlag, 2006-10)
Germination of Bacillus anthracis spores involves rehydration of the spore interior and rapid degradation of several of the protective layers, including the spore coat. Here, we examine the temporal changes that occur ...
A new two-site model for hydroxyapatite dissolution in acidic media
(Elsevier, 1978-11)
A physical model featuring two distinct types of dissolution sites for hydroxyapatite (HAP) crystals is presented. One of these sites (site No. 1) is associated with dissolution along c axis dislocations of HAP crystals ...
Poly(organophosphazene)s and the sol–gel technique
(John Wiley & Sons, Ltd., 1999-05)
We report a survey of the utilization of phosphazene materials in combination with metal alkoxide precursors to form ceramics through the sol–gel technique. Silicon, titanium, zirconium and aluminum three-dimensional oxide ...
