Role of bacterial efflux pumps in antibiotic resistance, virulence, and strategies to discover novel efflux pump inhibitors

open access: yesMicrobiology, 2023
The problem of antibiotic resistance among pathogenic bacteria has reached a crisis level. The treatment options against infections caused by multiple drug-resistant bacteria are shrinking gradually. The current pace of the discovery of new antibacterial

Quantifying the Ocean's Biological Pump and Its Carbon Cycle Impacts on Global Scales.

open access: yesAnnual Review of Marine Science, 2022
The biological pump transports organic matter, created by phytoplankton productivity in the well-lit surface ocean, to the ocean's dark interior, where it is consumed by animals and heterotrophic microbes and remineralized back to inorganic forms.

Quantifying the Carbon Export and Sequestration Pathways of the Ocean's Biological Carbon Pump

open access: yesGlobal Biogeochemical Cycles, 2022
The ocean's biological carbon pump transfers carbon from the surface ocean to the deep ocean by several distinct pathways, including gravitational settling of organic particles, mixing and advection of suspended organic carbon, and active transport by ...

To Pump or Not to Pump [PDF]

open access: yesDiabetes Care, 2002
First fully described in 1983, intensive insulin therapy attempts to match the levels of insulin in the blood with the physiologic needs of the diabetic patient (1). The results of the Diabetes Control and Complications Trial solidified the importance of this approach to the prevention of microvascular complications of diabetes (2).
