Proton Quantum Tunneling: Influence and Relevance to Acidosis-Induced Cardiac Arrhythmias/Cardiac Arrest.

Acidosis and its associated pathologies predispose patients to develop cardiac arrhythmias and even cardiac arrest. These arrhythmias are assumed to be the result of membrane depolarization, however, the exact mechanism of depolarization during acidosis is not well defined. In our study, the model of quantum tunneling of protons is used to explain the membrane depolarization that occurs during acidosis.

Mathematical Modeling of Ion Quantum Tunneling Reveals Novel Properties of Voltage-Gated Channels and Quantum Aspects of Their Pathophysiology in Excitability-Related Disorders.

Voltage-gated channels are crucial in action potential initiation and propagation and there are many diseases and disorders related to them. Additionally, the classical mechanics are the main mechanics used to describe the function of the voltage-gated channels and their related abnormalities. However, the quantum mechanics should be considered to unravel new aspects in the voltage-gated channels and resolve the problems and challenges that classical mechanics cannot solve.

Preoperative Dexamethasone for Airway-Related "Calibration Tube" Complications After Sleeve Gastrectomy: a Randomised Clinical Trial.

Background: Bariatric surgeries utilise Bougie device to guide stomach resection. The device implementation is associated with many underreported complications. This study aims to compare nebulised vs.

Biliary tree neuroendocrine tumor, an incidental finding.

Introduction And Importance: Biliary tree neuroendocrine tumors (NET) are rare, with 100 cases in the literature, and have an excellent prognosis. Although they are rarely diagnosed before surgery, complete surgical excision offers optimal treatment.

Case Presentation: We report a case of a 36-year-old female patient referred to the surgical team with obstructive jaundice for which she was investigated and found to have a common bile duct tumor showing proximal obstruction.

Patients response to pre-operative counseling for the appropriate type of bariatric surgery.

Introduction: Obesity is a major cause of metabolic and health disorders like diabetes mellitus (DM) and gastro esophageal reflux disease (GERD). Patients usually offered a professional preoperative consultation and objective information regarding the bariatric surgery type and the advantages and disadvantages of each type for best outcome and satisfaction.

Purpose: To study the patient response to preoperative advice and recommendation and the patient's decision to undergo the recommended bariatric surgery.

An isolated congenital absence of nasal columella: A case report and review of literature.

Introduction: The nasal columella is an important aesthetic and functional entity of the midface. Congenital absence of the nasal columella as an isolated anomaly is extremely rare.

Presentation Of Case: We present a case of total congenital aplasia of the nasal columella in a 3-month-old female infant.
