Local Anesthetic “Resistance”

open access: yesPain Physician, 2003
The incidence of inadequate analgesia despite technically well performed injections led our clinic to prospectively test patients for response to a variety of local aesthetics. Skin testing was performed on the skin of the forearm away from the site of pathology. Patients were asked to identify "which is the most numb" of the skin wheals. Although most

Cardiovascular and central actions of local anesthetics

open access: yes, 2016
thesis has discussed the common cardiovascular and CNS toxicity problems which may be observed and how to treat them or even better, prevent them in a clinical situation. The importance of lipid solubility of the local anesthesias was discussed in great

A Holistic Platform Approach for Developing Robust Pulmonary mRNA Delivery: Integrating Novel Phenolic Acid‐Derived Ionizable Lipids and Device Engineering

open access: yesAdvanced Functional Materials, EarlyView.
An integrated pulmonary mRNA delivery platform combining novel biodegradable syringic acid‐derived ionizable lipids, design‐of‐experiments formulation optimization, and vibrating‐mesh nebulizer engineering enabled stable aerosolization and efficient lung delivery.

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

Bupivacaína racêmica a 0,5% e mistura com excesso enantiomérico de 50% (S75-R25) a 0,5% no bloqueio do plexo braquial para cirurgia ortopédica. Estudo comparativo Bupivacaína racémica a 0,5% y mezcla con exceso enantiomérico del 50% (S75-R25) a 0,5% en el bloqueo del plexo braquial para cirugía ortopédica. Estudio comparativo Comparative study of 0.5% racemic bupivacaine versus enantiomeric mixture (S75-R25) of 0.5% bupivacaine in brachial plexus block for orthopedic surgery

open access: yesRevista Brasileira de Anestesiologia, 2005
JUSTIFICATIVA E OBJETIVOS: Com a finalidade de encontrar uma droga mais segura que a bupivacaína racêmica, vários estudos foram realizados com seus isômeros.

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,

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.

Current Concepts of the Mechanism of Action of Local Anesthetics

open access: yes, 1981
Recent experiments are reviewed to present a current view of the mechanisms of conduction block by local anesthetics. Local anesthetics block the sodium channels whose opening causes the rising phase of the action potential.
