Effect of Phenylephrine on the Accommodative System

open access: yesJournal of Ophthalmology, 2016
Accommodation is controlled by the action of the ciliary muscle and mediated primarily by parasympathetic input through postganglionic fibers that originate from neurons in the ciliary and pterygopalatine ganglia.

Acute cardio‐centric haemodynamic management preserves chronic cardiovascular function in pigs with high‐thoracic spinal cord injury

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Recent work has shown that treating the reduction in heart function following acute spinal cord injury (SCI) better optimizes peripheral haemodynamics and spinal cord oxygenation than the standard approach of using vasopressors.

A comparative study of the local effect of tranexamic acid and phenylephrine on the amount of bleeding in rhinoplasty: A randomized clinical trial [PDF]

open access: yesCaspian Journal of Internal Medicine
Background: Bleeding during nose surgery is very important, because it can cause a problem in the surgeon's field of view and lead to an increase in the probability of surgical complications.

Comparing prophylactic effect of phenylephrine and ephedrine on hypotension during spinal anesthesia for hip fracture surgery

open access: yesAdvanced Biomedical Research, 2016
Background: Spinal anesthesia is an accepted technique in hip fracture surgery and prevention of this complication by sympathomimetic agents is of potential clinical significance.

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

Differential contribution of T-type voltage-gated calcium channels to vascular reactivity in the aorta and renal artery of healthy rabbits. [PDF]

open access: yesExp Physiol
Abstract figure T‐type VGCCs contribute to the contraction of the rabbit aorta and modulate both contraction and vasodilation in the rabbit renal artery. α1, alpha 1 adrenergic receptor; ATR, angiotensin II receptor; Ang II, angiotensin II; CaM, calmodulin; Cav3, T‐type voltage‐gated Ca2⁺ channels; cGMP, cyclic guanidine monophosphate; EC, endothelial ...

Paediatric Nasogastric Tube Insertion Practices Across Australia and New Zealand: A Survey of Clinicians

open access: yesEmergency Medicine Australasia, Volume 38, Issue 2, April 2026.
ABSTRACT Background Nasogastric tube (NGT) insertion is common and is associated with significant distress when performed in paediatrics. There is limited literature on methods to reduce pain and distress in children and adolescents. Objectives To (i) determine current self‐reported practices of Australia and New Zealand clinicians relating to ...

Tacrolimus Induced Hypertension and Vascular Remodeling Includes Mechanisms of Cellular Senescence—The Protective Effect of Valsartan

open access: yesActa Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Aim Calcineurin inhibitors (CNI) such as tacrolimus (Tac) are the first‐line treatment to prevent transplant rejection. However, CNI have adverse effects on blood vessels and renal function, which may be linked to cellular senescence. Valsartan, a common angiotensin II type 1 receptor (AT1R) blocker, exhibits anti‐senescence properties.

ZNF384‐Driven Fibulin‐1 Exacerbates Vascular Stiffness via TGF‐β/Smad3‐Mediated Senescence and Fibrosis

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
This article elucidates the regulatory molecular mechanisms of Fibulin‐1 (Fbln1) in vascular stiffness and explores potential therapeutic interventions. Zinc Finger Protein 384 (ZNF384) binds to the Fbln1 promoter, driving its expression. Fbln1 activates the TGF‐β/Smad3 axis, promoting vascular smooth muscle cell (VSMC) senescence and collagen ...
