Effectiveness of cyclopentolate 1% compared to the combination of cyclopentolate 1%, tropicamide 1%, and phenylephrine 10% in cycloplegic refractive examination

open access: yesJournal of Clinical Ophthalmology and Research
Context: Refractive errors in children require appropriate eyeglass correction. Cycloplegic refraction is a method used to determine eyeglass prescriptions in children due to their high accommodative power.

Noradrenergic regulation of skeletal muscle oxygen pressures: Impact of heart failure with preserved ejection fraction and heat therapy

open access: yesExperimental Physiology, EarlyView.
Abstract Attenuation of sympathetic vasoconstriction during exercise (functional sympatholysis) contributes to skeletal muscle oxygen delivery–utilization matching. However, the extent to which muscle contractions impact noradrenergic regulation of interstitial oxygen pressures (PO2is${P_{{{\mathrm{O}}_2}}}_{{\mathrm{is}}}$; the driving force for blood–

Bilateral dynamic cerebral autoregulation assessment during endovascular treatment in large‐vessel occlusion stroke

open access: yesExperimental Physiology, EarlyView.
Abstract Recanalization by endovascular treatment (EVT) is effective in acute ischaemic stroke caused by large‐vessel occlusion. Better understanding of the pathophysiology could possibly identify targets for improving peri‐procedural management and thereby patient outcome.

Prophylactic Effectiveness of Phenylephrine 100 mcg and Ephedrine 10 mg on the Incidence of Spinal Anesthesia Induced Hypotension in Patients Undergoing Cesarean Section

open access: yesIndonesian Journal of Anesthesiology and Reanimation (IJAR)
Introduction: Birth by cesarean section (C-section) has increased significantly, with a high risk of maternal hypotension due to spinal anesthesia.

Pulmonary arterial mechanoreceptors mediate sustained sympathoexcitation during high altitude hypoxia in humans

open access: yesExperimental Physiology, EarlyView.
Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

Severe hypertension and pulmonary edema associated with systemic absorption of topical phenylephrine in a child during retinal surgery

open access: yesSaudi Journal of Anaesthesia, 2012
Topical phenylephrine solutions are widely used in eye procedures to promote pupil dilation without cycloplegia. We report a case of intraoperative severe hypertension and acute pulmonary edema occurring in a child during retinal surgery after possible ...

Cells and ionic conductances contributing to spontaneous activity in bladder and urethral smooth muscle

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Cells and conductances contributing to spontaneous activity in the lower urinary tract. Bladder and urethra exhibit spontaneous contractions at both cellular and tissue levels. Both detrusor and urethral smooth muscle cells display activity that is regular and rhythmic.

Comparison of hemodynamic response and vasopressor requirement following spinal anaesthesia between normotensive and severe preeclamptic women undergoing caesarean section: A prospective study

open access: yesJournal of Obstetric Anaesthesia and Critical Care, 2013
Background: Spinal anesthesia is the technique of choice in cesarean sections, but it is not widely accepted in severe pre-eclampsia due to fear of sudden and extensive sympathetic blockade. The aim of the present study was to compare the heart rate (HR),

Update on cellular expression and function of ANO1 channels in urethral smooth muscle

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Activation of ANO1 channels and resulting Cl− efflux are suggested to modulate urethral smooth muscle contractility by enhancing Ca2+ influx via voltage‐dependent Ca2+ entry and resulting contraction in urethral smooth muscle cells.
