Lactate orchestrates metabolic hemodynamic adaptations through a unique combination of venocontraction, artery relaxation, and positive inotropy

open access: yesActa Physiologica, Volume 241, Issue 5, May 2025.
Abstract Aim H+ facilitates metabolic blood flow regulation while negatively impacting cardiac contractility. Cardiovascular consequences of conjugate bases accumulating alongside H+ remain unclear. Here, we evaluate the cardiovascular effects of nine prominent carboxylates—particularly lactate, 3‐hydroxybutyrate, and butyrate—linked to metabolic and ...

Use of Fluid Gelatin in Lumbar Spinal Stenosis Undergoing Unilateral Biportal Endoscopic: A Prospective, Randomized Controlled Trial

open access: yesOrthopaedic Surgery, Volume 17, Issue 5, Page 1340-1348, May 2025.
The 96 patients were randomly assigned to two groups: the Surgiflo Hemostatic Matrix (SHM) group and the non‐SHM group. The use of fluid gelatin effectively reduces intraoperative and postoperative bleeding without leading to additional complications.

Determinants of cardiac output in health and heart failure

open access: yesExperimental Physiology, Volume 110, Issue 5, Page 637-648, 1 May 2025.
Abstract Sustained physical exercise depends on delivery of oxygenated blood to exercising muscle. At least among healthy individuals, bulk transport of blood is tightly matched to metabolic demand, such that cardiac output increases by ∼6 L/min for every 1 L/min increase in oxygen uptake. Multiple factors contribute to the regulation of cardiac output,

Cardiac output limits maximal oxygen consumption, but what limits maximal cardiac output?

open access: yesExperimental Physiology, Volume 110, Issue 5, Page 666-674, 1 May 2025.
Abstract Maximal oxygen uptake/consumption is an important variable determining exercise performance. It is generally considered to be limited largely, but not exclusively, by maximal cardiac output (CO), which limits the ability of heart to pump oxygen‐rich arterial blood to working muscles. Cardiac output is a product of heart rate and stroke volume,

A Comparative Study on the Effect of Aloe Vera and Nitroglycerin Ointment on the Incidence and Severity of Phlebitis Caused by the Peripheral Catheter

open access: yesمجله علمی دانشگاه علوم پزشکی کردستان, 2020
Background and Aim: In addition to modern medical advances, intravenous treatment has become an essential part of patient care. Intravenous treatment like other invasive techniques has its own side effects.
