QUININ IN PNEUMONIA. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1905
In thirteen consecutive cases of pneumonia developing in the course of a recent epidemic of that disease among the Indian school children on this reservation, the patients were treated by large doses of quinin, according to the method advocated by Galbraith, 1 without mortality.

Glycemic effects of quinine infusion in healthy volunteers

open access: yesBMC 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

Click'n ROPISA: One‐Pot Synthesis of Ultrabright Fluorescent Nanoparticles Made of Polypeptides

open access: yesAngewandte Chemie, EarlyView.
Self‐assembly and fluorophore conjugation proceed rapidly in a one‐pot “Click'n ROPISA” process, yielding intensely fluorescent polypeptide nanoparticles with tunable visible emission. High dye loading enables efficient energy transfer and single‐particle visualization, while the straightforward synthesis provides versatile access to bright ...

Emergence of Chiral Defective Pores Through Chiral Linker Exchange in Nonchiral MOFs for Enantioselective Recognition

open access: yesAngewandte Chemie, EarlyView.
Chiral recognition remains challenging due to minimal property differences. This work develops chiral defective MOFs via linker exchange to enable rapid, direct, luminescent enantioselective sensing, offering a simple, modular strategy that broadens MOF functionality for portable, low‐cost applications in pharmaceuticals, food safety, and environmental

A Blue Emissive Heavy Atom‐Free Multiresonant Thermally Activated Delayed Fluorescent Emitter Shows Ultra‐Fast Reverse Intersystem Crossing

open access: yesAngewandte Chemie, EarlyView.
The extended π‐system and low‐lying n‐π∗ transition endow DDOBDiKTa with a synergistic combination of strong spin‐orbit coupling, small reorganization energy and small ΔEST, enabling this blue boron‐nitrogen‐carbonyl hybrid emitter to achieve a fast kRISC of 6.34 × 106 s−1 together with OLEDs showing small efficiency roll‐off, with EQEmax/EQE10000 of ...

The Role of Quinine-Responsive Taste Receptor Family 2 in Airway Immune Defense and Chronic Rhinosinusitis

open access: yesFrontiers in Immunology, 2018
BackgroundBitter (T2R) and sweet (T1R) taste receptors in the airway are important in innate immune defense, and variations in taste receptor functionality in one T2R (T2R38) correlate with disease status and disease severity in chronic rhinosinusitis ...
