Vasodilators in Septic Shock Resuscitation: A Clinical Perspective [PDF]

open access: yes, 2017
: Microcirculatory abnormalities have been shown to be frequent in patients with septic shock despite “normalization” of systemic hemodynamics. Several studies have explored the impact of vasodilator therapy (prostacyclin, inhaled nitric oxide, topic ...

Intravenous methadone for pain management in cardiac surgery: a randomised controlled trial with plasma concentration analysis*

open access: yesAnaesthesia, Volume 81, Issue 1, Page 51-61, January 2026.
Summary Introduction Postoperative pain after cardiac surgery remains significant despite the administration of opioids. Methadone may improve pain control and decrease the need for postoperative opioids. Randomised controlled trials, however, are limited and the effects of cardiopulmonary bypass on methadone pharmacokinetics are unclear.

Human hypoxia models in aerospace medicine: Potential applications for human pharmacological research

open access: yesBritish Journal of Clinical Pharmacology, Volume 92, Issue 1, Page 58-72, January 2026.
Aerospace medicine required controlled terrestrial models to investigate influences of altered atmosphere conditions, such as hypoxia, on human health and performance. These models could potentially be expanded to encompass disease conditions or treatment targets regulated through hypoxia or hypercapnia.

Dietary flavanols preserve upper‐ and lower‐limb endothelial function during sitting in high‐ and low‐fit young healthy males

open access: yesThe Journal of Physiology, Volume 604, Issue 1, Page 145-171, 1 January 2026.
Abstract figure legend Schematic indicating the design of an acute randomised, counterbalanced, double‐blinded, cross‐over, placebo‐controlled human study in which 20 high‐fit males and 20 low‐fit males consumed either a low‐flavanol (5.6 mg) or a high‐flavanol (695 mg) cocoa drink prior to a 2 h uninterrupted sitting bout.

The nitrite anion: the key intermediate in alkyl nitrates degradative mechanism. [PDF]

open access: yes, 2007
Alkyl nitrates, _in vivo_, are metabolized to yield nitric oxide, and thiol groups are considered necessary cofactors. This statement is based on studies that underline how these species potentiate hemodynamic responsiveness to nitrates in patients with ...
