STUDIES OF THE ACID-BASE EQUILIBRIUM IN DISEASE FROM THE POINT OF VIEW OF BLOOD GASES

open access: yesJournal of Experimental Medicine, 1921
Carbon dioxide diagrams (Haggard and Henderson (9)) have been constructed for the blood of a series of hospital patients as a method of studying disturbances in their acid-base equilibrium.

The prebiotic evolutionary advantage of transferring genetic information from RNA to DNA. [PDF]

open access: yes, 2011
In the early 'RNA world' stage of life, RNA stored genetic information and catalyzed chemical reactions. However, the RNA world eventually gave rise to the DNA-RNA-protein world, and this transition included the 'genetic takeover' of information storage ...

The Acid-base Equilibrium of Epinephrectomized Cats.

open access: yesExperimental Biology and Medicine, 1926
Because of striking changes in certain of the blood constituents, especially phosphorus, which follow adrenal extirpation in cats, and the fact that these animals present unusual changes in respiration a few hours preceding coma and death, it seemed probable that acid intoxication was one of the train of symptoms leading to death from epinephrectomy ...

Fluorescence and photostability studies of anthracene-9-carboxylic acid in different media

open access: yesInternational Journal of Photoenergy, 2000
Electronic absorption and fluorescence spectra of anthracene-9-carboxylic acid (ANCA) were studied in different homogeneous solvents, binary protic/aprotic solvent mixtures and in heterogeneous solutions of the cationic cetyltrimethyl ammonium bromide ...

TOTAL ACID-BASE EQUILIBRIUM OF PLASMA IN HEALTH AND DISEASE: XII. A Study of Renal Edema.

open access: yesJournal of Clinical Investigation, 1929
In a study of the metabolism of patients with nephrosis and the nephrotic type of glomerular nephritis, the total acid-base equilibrium in the serum has been determined by a procedure described in previous papers of this series (1, 2).

Protolytic equilibria in homogeneous and heterogeneous systems of ketoconazole and its direct spectrophotometric determination in tablets [PDF]

open access: yesJournal of the Serbian Chemical Society, 2005
The acid-base equilibria of a diprotic, slightly hydrosoluble base ketoconazole were studied in homogeneous and heterogeneous water systems. The determinations were performed at 25ºC at a constant ionic strength of M(NaCl).

A detailed UV–Vis spectral investigation of six azo dyes derived from benzoic- and cinnamic acids: experimental and theoretical insight

open access: yesComptes Rendus. Chimie, 2021
Six donor–${\pi }$–acceptor azo dyes, with altered donor- (p-hydroxyphenyl- and naphthalene-2-ol) and carboxylic based acceptor groups, were subjected to detailed solvatochromic and tautomeric investigation in different environments by experimental and ...

Modelling of non-steady-state concentration profiles at ISFET-based coulometric sensor—actuator systems [PDF]

open access: yes, 1990
Acid or base concentrations can be determined very rapidly by performing an acid—base titration with coulometrically generated OH− or H+ ions at a noble metal actuator electrode in close proximity to the pH-sensitive gate of an ion-sensitive field effect

TOTAL ACID-BASE EQUILIBRIUM OF PLASMA IN HEALTH AND DISEASE: X. The Acidosis of Nephritis.

open access: yesJournal of Clinical Investigation, 1929
The present paper represents an extension of the work outlined in number VII of this series, "Factors causing acidosis in nephritis" (1), with an attempt to explain in part the disturbances of the total acidbase equilibrium of the serum which were there ...
