The outer membrane (OM) of gram-negative bacteria forms a protective layer around the cell that serves as a permeability barrier to prevent unrestricted access of noxious substances. The permeability ...

The permeability of biological membranes is a key determinant of drug pharmacokinetics. Historically, passive diffusion through the lipid bilayer portion of a biological membrane was suggested as the ...

Impact of dose density of adjuvant chemotherapy for locally advanced urothelial cancer. Background: Device-assisted intravesical mitomycin-C (MMC), including electromotive administration (EMDA) and ...

Passive diffusion plays an essential role in oral absorption of drugs through the gastrointestinal tract, penetration across the blood-brain barrier to reach Central Nervous System disease targets, ...

Do clinical practice guidelines (CPGs) change clinical practice? An analysis of CPG impact on referral and treatment patterns for neoadjuvant chemotherapy in bladder cancer No significant financial ...

A simple passive diffusion model is used to analyze the local within-habitat dispersal of twelve species of herbivorous insects. The data comprise field mark-recapture studies in relatively ...

Cells continuously move materials in and out through their cell walls. Facilitated transport is one way of moving those materials without expending cellular energy. In facilitated transport, materials ...

You dip your teabag into a cup of boiling water and watch the clear steaming liquid slowly change into an inviting rich red. The laws by which the particles of tea spread from the source of high ...
