Upregulation of SIRT1 deacetylase in phenylephrine-treated cardiomyoblasts [PDF]

, 2011
The sirtuin SIRT1 is an ubiquitous NAD+ dependent deacetylase that plays a role in biological processes such as longevity and stress response. In cardiac models, SIRT1 is associated to protection against many stresses. However, the link between SIRT1 and

Intraoperative Bradycardia: Evaluating Vasovagal Events in Adult Suspension Microlaryngeal Surgery

The Laryngoscope, EarlyView.
This retrospective single‐surgeon cohort study of 190 adults undergoing suspension microlaryngoscopy found that 8.9% (17/190) developed significant intraoperative bradycardia consistent with a vasovagal response (VVR). No demographic, comorbidity, or procedural factors were significantly associated with VVR, though most affected patients required ...

Vasopressor-Associated Limb Ischemia Resulting in Quadruple Amputation in Suspected Septic Shock. [PDF]

Clin Case Rep
ABSTRACT Vasopressor‐associated limb ischemia (VALI) is a rare but devastating complication of vasopressor therapy in septic shock. This case shows catastrophic four‐limb amputation in a 26‐year‐old obese male with suspected septic shock. This case illustrates the complex interplay between prolonged high‐dose vasopressor therapy, morbid obesity, and ...

Comparing the effect of hypotension treatment due to spinal anesthesia with ephedrine or phenylephrine on arterial blood gases and neonatal Apgar score during cesarean delivery in obese mothers: randomized clinical trial [PDF]

Majallah-i Zanān, Māmā̓ī va Nāzā̓ī-i Īrān, 2019
Introduction: Hypertension in obese patients is more affected by spinal anesthesia than normal people. Due to the lack of study and recommendation of articles about comparison of ephedrine and phenylephrine in obese patients during cesarean section, this

Prolonged Bradycardia After Phenylephrine Administration

, 2020
Background: Phenylephrine is the first line vasopressor for prophylaxis and treatment in cases of hypotension due to spinal anesthesia in obstetrics. Phenylephrine binds to alpha-1 receptors leading to venous and arterial vasoconstriction. Because of its

Merger Efficiency and Coordinated Effects: Nothing to Sneeze at? Evidence From Cough and Cold Medicines in the Philippines

Southern Economic Journal, EarlyView.
ABSTRACT We investigate the competitive effects of a merger in the cough and cold medicines segment between GlaxoSmithKline (GSK) and Pfizer. The parties offered efficiency gains, and authorities concluded the merger would not lessen competition. Using product‐level data from the Philippines, we estimate a structural demand model to assess efficiency ...

Effect of Ultra-Violet Irradiation of Phenylephrine Solutions

, 1963
Solutions of phenylephrine in distilled water were irradiated with ultra-violet light for 3 hr. The irradiated solutions tested on perfused guinea-pig lungs had a bronchodilator potency greater than that of the original non-irradiated phenylephrine ...
