Dexmedetomidine Prolongs the Duration of Ropivacaine Corneal Anesthesia After Subconjunctival Injection in Healthy Horses

Veterinary Ophthalmology, EarlyView.
ABSTRACT Objective To determine whether dexmedetomidine prolongs corneal anesthesia following subconjunctival ropivacaine injection in healthy equine eyes. Methods Ten horses with normal ophthalmic exams were enrolled in a randomized, blinded, crossover experiment with a minimum 4‐week washout between treatments. Baseline corneal touch thresholds (CTT,

Ultrasonographic Ocular Biometry of the Greater Caribbean Manatee (Trichechus manatus manatus)

Veterinary Ophthalmology, EarlyView.
ABSTRACT This study aimed to characterize the ocular biometry of the Trichechus manatus manatus applying B‐mode ultrasonography across different age groups. Twenty‐two animals were assessed employing a portable ultrasound device equipped with a linear transducer. Five ocular parameters were assessed: corneal thickness (CT), anterior chamber depth (ACD),

Phenylephrine does not improve oxygenation during one-lung ventilation: A randomized, double-blind, cross-over study.

PLoS ONE, 2018
BackgroundPhenylephrine is an α1 adrenergic receptor agonist that causes pulmonary vasoconstriction, and so may effectively enhance hypoxic pulmonary vasoconstriction (HPV).

Nitrite supplementation alleviates cerebrovascular dysfunction in chronically stressed mice, but cognitive decline remains

Experimental Physiology, EarlyView.
Abstract This study aimed to determine whether sodium nitrite supplementation prevented chronic stress‐induced cerebrovascular dysfunction and cognitive decline. We hypothesize that nitrite supplementation will prevent the oxidative environment and cerebrovascular dysfunction associated with chronic stress and maintain cognitive health.

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

Experimental 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–

Ouabain‐induced hypertension in rats: Mechanisms, variability and translational implications

Experimental Physiology, EarlyView.
Abstract Ouabain‐induced hypertension is a multifactorial and condition‐dependent phenomenon involving coordinated actions across vascular, renal and central nervous system pathways. At the vascular level, ouabain inhibits Na⁺/K⁺‐ATPase, particularly the α2‐isoform, leading to elevated intracellular Ca2⁺, enhanced vasoconstriction and structural ...
