WebJan 31, 2013 · The blood–brain barrier (BBB) restricts the entry of circulating drugs and xenobiotics into the brain, and thus its permeability to substances is a critical factor that determines their central effects. The infant brain is vulnerable to neurotoxic substances partly due to the immature BBB. The employment of in vitro BBB models to evaluate … WebNov 19, 2024 · The blood–gas partition coefficient (λb/g), or Ostwald coefficient for blood–gas, is a pharmacological term used to describe the solubility of a volatile anaesthetic agent.

WebSep 16, 2024 · Scores in two of the most internationally used intelligence tests, the Wechsler’s Adult Intelligence Scale (WAIS) and Raven’s Progressive Matrices (RPM), typically have a correlation coefficient of ~0.7 or higher, despite being assessed in almost entirely different settings ( McLeod and Rubin 1962 ). WebIn this paper, a method for estimating snow pressure reflection coefficient based on non-contact ultrasound examination is described. A constant frequency and air-coupled ultrasound pulses were used in this study, which incorporates a parametric method for reflected energy estimation. The experimental part was carried out in situ in the Antarctic, …
