Glycemic effects of quinine infusion in healthy volunteers

BMC Research Notes, 2017
Background We aimed to quantify the glycemic effects of quinine in healthy individuals. Methods We evaluated the glycemic profile in response to 4 h infusion of 500 ml of 0.9% saline versus 5% glucose solution with and without quinine at therapeutic dose

Fluorescent quinine-based tracking techniques for measurement of open-channel surface flow velocities under low luminosity conditions using a UAS

Hydrology Research, 2023
This study presents techniques based on the use of fluorescent quinine as a visual tracer for surface flows, to assess surface flow velocities in channels and streams under low luminosity conditions.

Intragastric administration of the bitter tastant, quinine, lowers the glycemic response to a nutrient drink without slowing gastric emptying, in healthy men.

American Journal of Physiology. Regulatory Integrative and Comparative Physiology, 2019
Gastric emptying and the release of gastrointestinal (GI) hormones are major determinants of postprandial blood glucose concentrations and energy intake.

Reimagining o‐Carborane‐Based Fluorophores: Charge‐Transfer from Boron Substituents Triggers Aggregation‐ and Crystallization‐Induced Emission

Angewandte Chemie, EarlyView.
This work reports, for the first time, aggregation‐ or crystallization‐induced emission in boron‐substituted carboranes, which was driven by photoinduced charge‐transfer from fluorophore attached via boron vertices. The emission properties can be tuned by varying the substituents, expanding design strategies for luminescent materials.

A Mechanism Linking Two Known Vulnerability Factors for Alcohol Abuse: Heightened Alcohol Stimulation and Low Striatal Dopamine D2 Receptors [PDF]

, 2019
Alcohol produces both stimulant and sedative effects in humans and rodents. In humans, alcohol abuse disorder is associated with a higher stimulant and lower sedative responses to alcohol.

Alcohol preferring P rats exhibit aversion resistant drinking of alcohol adulterated with quinine

bioRxiv, 2019
Understanding why some people continue to drink alcohol despite negative consequences and others do not is a central problem in the study of alcohol use disorder (AUD).

In vivo assessment of drug efficacy against Plasmodium falciparum malaria: duration of follow-up. [PDF]

, 2004
To determine the optimum duration of follow-up for the assessment of drug efficacy against Plasmodium falciparum malaria, 96 trial arms from randomized controlled trials (RCTs) with follow-up of 28 days or longer that were conducted between 1990 and 2003

Bitter-Induced Salivary Proteins Increase Detection Threshold of Quinine, But Not Sucrose.

Chemical Sensors, 2019
Exposures to dietary tannic acid (TA, 3%) and quinine (0.375%) upregulate partially overlapping sets of salivary proteins which are concurrent with changes in taste-driven behaviors, such as rate of feeding and brief access licking to quinine.

Innate and Acquired Quinine-Resistant Alcohol, but not Saccharin, Drinking in Crossed High Alcohol Preferring Mice.

Alcoholism: Clinical and Experimental Research, 2019
BACKGROUND Alcohol consumption despite aversive consequences is often a key component of an alcoholism diagnosis. Free-choice alcohol consumption despite bitter quinine adulteration in rodents has been seen following several months of free-choice ...
