Estudo comparativo entre bupivacaína a 0,25% e ropivacaína a 0,2% em anestesia peridural para cirurgia torácica Estudio comparativo entre bupivacaína a 0,25% y ropivacaína a 0,2% en anestesia peridural para cirugía de tórax Comparison between 0.25% bupivacaine and 0.2% ropivacaine in epidural anesthesia for thoracic surgery

open access: yesRevista Brasileira de Anestesiologia, 2001
JUSTIFICATIVA E OBJETIVOS: A anestesia peridural associada à anestesia geral tem sido usada em várias especialidades cirúrgicas. Em cirurgia torácica seu uso é pouco discutido na literatura. Este estudo teve como objetivo avaliar os efeitos hemodinâmicos

DETERMINATION BY^1H-NMR OF BINDING SITES OF LOCAL ANESTHETICS ON LIPID BILAYER MEMBRANE MODEL [PDF]

open access: yes, 1994
P(論文)局所麻酔薬の作用機序についてはさまざまな仮説があるが,どの仮説も十分な説明をしていない。そこで我々は核磁気共鳴装置(NMR)を用いて,局所麻酔薬と神経膜モデルであるリン脂質二重膜との結合状態を検索した。この結果,局所麻酔薬分子中にある窒素原子とリン脂質二重膜の外側にある親水性部分の酸素原子とが静電結合をおこすことが分かった。また我々が作用持続時間の延長を目的に合成した,リドカインのエステル誘導体では窒素原子との結合に加えて,エステルカルボニル部分の酸素原子でも膜と結合することもわかった。さらに,

A Magneto‐Mechanically Activated Nerve Guidance Conduit Promotes Peripheral Nerve Regeneration via TIMP1‐Mediated Membrane Tension Transfer

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a magneto‐mechanical strategy that incorporates FP@MSCs into an aligned PCL/GelMA nerve guidance conduit. Magnetic stimulation increases membrane tension in FP@MSCs, triggering cytoskeletal remodeling, Schwann cell‐like differentiation, and TIMP1 secretion. TIMP1 activates ITGB1/CD63–FAK signaling in NE‐4C cells, increasing membrane

Effects of Anesthetics on Barrier Tissue Function

open access: yesJournal of Immunology Research, 2019
Anesthetics have long been proven to have additional effects other than anesthesia on different organs and tissues of the human body. Barrier tissues play critical roles in human health and diseases, yet the impacts of anesthetics on barrier tissues are ...

Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft‐Tissue Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
Sea cucumber‐inspired gelatin hydrogels are formed by directional freezing and mechanically programmed through subsequent ionic treatment. Multiscale characterization and modeling link ion‐regulated chain interactions to directional load transfer within the aligned hierarchical architecture.
