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

The 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.

Intraoperative Collection of Ascitic Fluid With Intra‐ or Postoperative Reinfusion in Ovarian Cancer: Safety and Feasibility of a Roller Pumping Method

Therapeutic Apheresis and Dialysis, Volume 30, Issue 3, Page 371-376, June 2026.
ABSTRACT Introduction Patients with ovarian cancer often present with massive ascites, leading to significant protein loss during surgical procedures. Although cell‐free concentrated ascites reinfusion therapy (CART) is used in palliative settings to mitigate protein loss, its application in intraoperative settings remains unexplored.

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

Caspian 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.

Influence of central venous pressure upon sinus node responses to arterial baroreflex stimulation in man [PDF]

Measurements were made of sinus node responses to arterial baroreceptor stimulation with phenylephrine injection or neck suction, before and during changes of central venous pressure provoked by lower body negative pressure or leg and lower truck ...

Observation of cone and rod photoreceptors in normal subjects and patients using a new generation adaptive optics scanning laser ophthalmoscope. [PDF]

, 2011
We demonstrate the capability of a new generation adaptive optics scanning laser ophthalmoscope (AOSLO) to resolve cones and rods in normal subjects, and confirm our findings by comparing cone and rod spacing with published histology measurements.

Cardiovascular β‐Adrenergic Receptor Distribution and Function: Influence of Species, Sex, Age, and Tissue

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
Estrogen modulates β‐AR signaling in a context‐dependent manner influenced by species, sex, age, tissue, and vascular health, highlighting challenges in translating findings from experimental models to human cardiovascular physiology. ABSTRACT Cardiovascular diseases remain the leading global cause of morbidity and mortality, with notable sex‐specific ...

A polymer coated cicaprost-eluting stent increases neointima formation and impairs vessel function in the rabbit iliac artery [PDF]

, 2016
Drug-eluting stents have been successful in reducing in-stent restenosis but are not suitable for all lesion types and have been implicated in causing late stent thrombosis due to incomplete regeneration of the endothelial cell layer.

Gynaecological Laparoscopy Surgery Complicated Into CO2 Embolism, Cardiac Arrest and Severe ARDS Requiring ECMO Therapy

Respirology Case Reports, Volume 14, Issue 5, May 2026.
We report a case of CO2 embolism complicated by severe ARDS with refractory hypoxia requiring extracorporeal membrane oxygenation (ECMO) therapy, which resulted in a favourable outcome. ABSTRACT Laparoscopic surgeries have revolutionised surgical practice due to their advantages, including minimal invasiveness, fewer postoperative complications ...
