The free energy of biomembrane and nerve excitation and the role of anesthetics

open access: yes, 2018
In the electromechanical theory of nerve stimulation, the nerve impulse consists of a traveling region of solid membrane in a liquid environment. Therefore, the free energy necessary to stimulate a pulse is directly related to the free energy difference ...

Phase transitions in biological membranes

open access: yes, 2018
Native membranes of biological cells display melting transitions of their lipids at a temperature of 10-20 degrees below body temperature. Such transitions can be observed in various bacterial cells, in nerves, in cancer cells, but also in lung ...

Anesthetic salts used in dentistry: a literature review

open access: yesJournal Of Oral Investigations, 2017
Local anesthetics allow a better and suitable control of pain in patients that submit to dental treatments. The pharmacology of local anesthetics is too complex, therefore it is important to know how to select the correct drug to each procedure to be ...

Progress of Drug Controlled Release Systems for Local Anesthesia

open access: yesXiehe Yixue Zazhi, 2022
Reducing the drug administration times and prolonging the postoperative analgesia duration are important requirements of clinical local anesthesia. However, both local anesthetics currently used in the clinic and potentially new anesthetic drugs such as ...

Sweet-Tasting Ionic Conjugates of Local Anesthetics and Vasoconstrictors

open access: yesMolecules, 2021
Local anesthetics are widely utilized in dentistry, cosmetology, and medicine. Local anesthesia is essential to providing a pain-free experience during dental and local surgeries as well as cosmetic procedures.

Fusion of secretory vesicles isolated from rat liver [PDF]

open access: yes, 1978
Secretory vesicles isolated from rat liver were found to fuse after exposure to Ca2+. Vescle fusion is characterized by the occurrence of twinned vesicles with a continuous cleavage plane between two vesicles in freeze-fracture electron microscopy.

Perioperative and anesthetic deaths: toxicological and medico legal aspects [PDF]

open access: yes, 2019
Background: Anesthesia has become safer during decades, though there is still a preventable mortality; the complexity of medical and surgical interventions, increasingly older and sicker patients, has created a host of new hazards in anesthesiology.

Blocking the voltage‐gated sodium channel hNav1.5 as a novel pH‐dependent mechanism of action for tamoxifen

open access: yesFEBS Open Bio, EarlyView.
Patch‐clamp recordings revealed that tamoxifen inhibits voltage‐gated sodium channels, especially under acidic conditions, both common in metastatic cancer cells. These effects may explain certain antitumor properties of tamoxifen, highlighting a novel mechanism of action beyond its known endocrine effects.

Electrical pulse stimulation reflecting the episodic nature of real‐life exercise modulates metabolic and secretory profile of primary human myotubes

open access: yesFEBS Open Bio, EarlyView.
Here, we introduced an intermittent electrical stimulation protocol mimicking the episodic nature of real‐life exercise in vitro by alternating low‐ and high‐frequency stimulation. In comparison with widely used continuous stimulation, it enhanced the rate of glucose and fatty acid oxidation, but not the myokine release.
