The ionophore resistance genes narA and narB are geographically widespread and linked to resistance to medically important antibiotics [PDF]

mSphere
Ionophores are a class of antibiotics used widely in animal production as anti-coccidials and for growth promotion. Since ionophores are not used in human medicine, it has largely been assumed that they do not contribute to medically important ...

Calcium Ionophore (A23187) Rescues the Activation of Unfertilized Oocytes After Intracytoplasmic Sperm Injection and Chromosome Analysis of Blastocyst After Activation

Frontiers in Endocrinology, 2021
Calcium is a crucial factor in regulating the biological behavior of cells. The imbalance of calcium homeostasis in cytoplasm will cause abnormal behavior of cells and the occurrence of diseases.

Silacrown ionophores [PDF]

Journal of Membrane Science, 1987
A study is reported on the metal ion transport efficiency of various silacrown ether ionophores and their ethyleneoxy glycol hydrolysis products. The silacrowns are modified crown ethers in which an ethylene bridge has been replaced by a difunctional silyl group, e.g. dimethylsilyl.

Chemically modified field effect transistors: the effect of ion-pair association on the membrane potentials [PDF]

, 1994
A theoretical model has been developed which relates physically accessible parameters to the formation of a membrane potential. The description is an extension of a theoretical description presented previously by our group, now including divalent cations

The Potential of Shortening the Adaptation of Nellore Cattle to High-Concentrate Diets Using Only Virginiamycin as Sole Feed Additive

Frontiers in Veterinary Science, 2021
Feedlot cattle are usually adapted to high-concentrate diets containing sodium monensin (MON) in more than 14 days. However, for finishing diets with lower energy content, the use of MON during adaptation may hold dry matter intake (DMI), and ...
