At‐Home Early Diagnosis of Mastitis: Calibration‐Free Analysis of Sodium to Potassium Ratio in Breast Milk

open access: yesAdvanced Functional Materials, EarlyView.
MAMAWEL is introduced as the first calibration‐free potentiometric sensor for at‐home mastitis diagnosis. By measuring the sodium‐to‐potassium ratio in breast milk, the device reliably differentiates between healthy and mastitis‐affected samples with less than 10% error.

Treatment of Hypercholesterolemia with Nicotinic Acid [PDF]

open access: yesCirculation, 1958
Nicotinic acid was administered orally to 33 patients with hypercholesterolemia in doses varying from 1.5 to 6.0 Gm. per day for periods of 3 months to 1½ years. Significant, sustained, and reproducible decreases in the concentration of cholesterol and total lipids in the plasma and of serum beta-lipoprotein cholesterol were observed in a majority of ...

The effect of 3-indoleacetic acid on the response of Lactobacillus arabinosus 17-5 to nicotinamide [PDF]

open access: yes, 1949
Lactobacillus arabinosus 17-5 has been widely used as an assay organism for nicotinic acid (NA) since the development of the method by Snell and Wright (1). Although it has been realized that other substances present in tissue extracts may interfere with

The MX-Helix of Muscle nAChR Subunits Regulates Receptor Assembly and Surface Trafficking. [PDF]

open access: yes, 2020
Nicotinic acetylcholine receptors (AChRs) are pentameric channels that mediate fast transmission at the neuromuscular junction (NMJ) and defects in receptor expression underlie neuromuscular disorders such as myasthenia gravis and congenital myasthenic ...

Regions of beta 2 and beta 4 responsible for differences between the steady state dose-response relationships of the alpha 3 beta 2 and alpha 3 beta 4 neuronal nicotinic receptors [PDF]

open access: yes, 1995
We constructed chimeras of the rat beta 2 and beta 4 neuronal nicotinic subunits to locate the regions that contribute to differences between the acetylcholine (ACh) dose-response relationships of the alpha 3 beta 2 and alpha 3 beta 4 receptors ...

An examination of the putative glucose tolerance factor activity of amino acid and peptide fractions isolated from brewer's yeast : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Chemistry at Massey University [PDF]

open access: yes, 1985
The first report of the possible existance of a glucose tolerance factor (GTF) was made by Mertz and Schwarz (1955) who noticed that a dietary additive, termed factor 3, isolated from an enzymatic casein hydrolysate (Schwarz (1952)), maintained normal ...
