Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

The Italian hemodilution trial in acute stroke.

, 1987
The Italian Acute Stroke Study is a prospective, multicenter, randomized, clinical trial to evaluate hemodilution in acute stroke. Thirty-one centers will recruit 1,200 patients with a recent (less than 12 hours) hemispheric acute stroke.

Mechanisms reducing parasympathetic activity in chronic hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Parasympathetic activity is reduced in chronic hypoxia, but the underlying mechanism(s) are unclear. Using β‐adrenergic blockade to isolate parasympathetic control of heart rate at sea level and after 9‐12 days at high altitude, we investigated whether (i) chemoreflex activation, (ii) increased pulmonary ventilation and/or (iii ...

The changes of calculated arterial oxygen content during acute isovolemic hemodilution with Oxycyte® or albumin.

, 2013
Hemodilution causes a progressive decrease in Hct level. The arterial oxygen content decreases in an inverse proportion to the levels of Hct during hemodilution with either albumin or Oxycyte®.

Effects of fascial manipulation, vibration exercise, motor imagery, or neuro‐muscular electrical stimulation on the coagulation system: A pilot study

Physiological Reports
Available evidence suggests that various medical/rehabilitation treatments evoke multiple effects on blood hemostasis. It was therefore the aim of our study to examine whether fascial manipulation, vibration exercise, motor imagery, or neuro‐muscular ...

An in vitro study of coagulation evaluation in obstetric hemorrhage for pregnancy-induced hypertension with coagulation and platelet function analyzer

Hypertension in Pregnancy
This study aimed to establish in vitro hemodilution and resupplementation assays for obstetric hemorrhage in pregnancy-induced hypertension (PIH) and to monitor the coagulation function dynamically using a coagulation and platelet function analyzer ...

Ovarian cancer during pregnancy: Pregnancy‐adjusted inflammatory and haematologic signatures for earlier risk recognition and clinical decision‐making

Clinical and Translational Discovery, Volume 6, Issue 5, October 2026.
Pregnancy alters haematologic and inflammatory profiles, potentially masking ovarian cancer. Integrating trimester‐specific NLR, PLR, SII, CRP, CA‐125, haemoglobin, platelet dynamics, and imaging may improve risk stratification. Multimodal biomarkers, longitudinal monitoring, and multidisciplinary assessment can support earlier detection and ...

Coronary hemodynamic responses during local hemodilution in canine hearts

, 1988
To evaluate the effect of hemodilution per se on coronary hemodynamics, experiments were performed in 36 anesthetized, open-chest dogs whose left anterior descending coronary artery (LAD) was perfused selectively with either normal arterial blood or ...

Musculoskeletal (Mal)adaptations in Response to a > 30 000‐km Running Challenge

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 5, October 2026.
ABSTRACT Background Ultra‐endurance sports are increasingly popular, yet the long‐term physiological consequences of sustained extreme training loads remain poorly understood. In particular, the effects of prolonged ultra‐endurance exercise on skeletal muscle structure, function and molecular remodelling are largely unknown.
