Zeb2 Controls Retinal Physiological and Pathological Angiogenesis by Regulating Astrocyte Proliferation and Differentiation

Cell Proliferation, EarlyView.
During development, the oxygen‐sensitive transcription factor Zeb2 restrains astrocyte proliferation and maturation to ensure balanced retinal angiogenesis. In disease, it promotes the neurotoxic A1 astrocyte phenotype and inflammation, thereby promoting reparative revascularization over pathological neovascularization.

Effect of Phenylephrine on Cardiac Contractility and Adenyl Cyclase Activity

, 1971
Both phenylephrine and noradrenaline increased the force of contraction of isolated preparations of rabbit and chicken heart. Noradrenaline increased the rate of formation of cyclic 3′,5′-AMP in homogenate of rabbit or chicken heart, but phenylephrine ...

The Effects of Nasal and Multi‐Level Upper Airway Surgery on Upper Airway Collapsibility and Non‐Anatomical Endotypes in People With Obstructive Sleep Apnoea—A Pilot Study

Journal of Sleep Research, EarlyView.
ABSTRACT Nasal breathing is the preferred route of breathing during sleep. Indeed, nasal blockage can cause obstructive sleep apnoea (OSA) in otherwise healthy people. Whilst multi‐level pharyngeal surgery reduces OSA severity, efficacy varies and changes in OSA pathophysiology post‐surgery have not been well characterised.

Timing of intrapartum transfusion among obstetric patients, stratified by admission and discharge haemoglobin, relative to anaesthesia care: A retrospective cohort study

Transfusion Medicine, EarlyView.
Abstract Background We previously validated and implemented criteria for auditing anaesthesiologists with intraoperative transfusion based on low median blood loss of the surgical procedure or absence of anaemia before transfusion. However, obstetrical cases were excluded during implementation, as the peripartum blood management protocol does not ...

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

Journal 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.

Vasoactive peptides and phenylephrine actions in isolated teleost hepatocytes

, 1990
The metabolic actions of the vasoactive peptides vasotocin and isotocin and the alpha-agonist phenylephrine are examined in hepatocytes isolated from three teleost species: brown bullhead, rainbow trout, and American eel.

Bilateral simultaneous cataract surgery and intraocular lens implantation in an adult female chimpanzee (Pan troglodytes) inducing monovision

Veterinary Ophthalmology, Volume 28, Issue 2, Page 457-464, March 2025.
Abstract Background Cataract is the major cause of visual impairment in humans. Phacoemulsification with intraocular lens (IOL) implantation is the standard technique for cataract treatment with a high success rate. In a few cases, the surgical cataract procedure and lens implantation have been applied in non‐human primates.

Traction suture fixation technique using a capsular tension ring fragment for severe lens displacement during cataract surgery in dogs

Veterinary Ophthalmology, Volume 28, Issue 2, Page 197-206, March 2025.
Abstract Objectives To describe the traction suture fixation technique for severely displaced lenses (≥180°) using a capsular tension ring (CTR) fragment during cataract surgery in dogs, and to retrospectively investigate its clinical outcomes. Animals Studied Eight dogs (nine eyes). Procedures The medical records of dogs with severe lens displacement (
