Simpson L, Hansen A, Moralez G, Amin S, Hofstaetter F, Gasho C, et al.
Am J Physiol Regul Integr Comp Physiol
. 2023 Jan;
324(4):R457-R469.
PMID: 36717165
Sympathetic transduction is reduced following chronic high-altitude (HA) exposure; however, vascular α-adrenergic signaling, the primary mechanism mediating sympathetic vasoconstriction at sea level (SL), has not been examined at HA. In...

Marume K, Mugele H, Ueno R, Amin S, Lesmana H, Possnig C, et al.
Eur J Appl Physiol
. 2023 Jan;
123(5):1091-1099.
PMID: 36645478
Purpose: Resistance training (RT) is an effective countermeasure to combat physical deconditioning whereby localized hypoxia within the limb increases metabolic stress eliciting muscle adaptation. The current study sought to examine...

Hansen A, Moralez G, Amin S, Hofstatter F, Simpson L, Gasho C, et al.
J Physiol
. 2022 Jun;
600(15):3483-3495.
PMID: 35738560
Chronic exposure to hypoxia (high-altitude, HA; >4000 m) attenuates the vasodilatory response to exercise and is associated with a persistent increase in basal sympathetic nerve activity (SNA). The mechanism(s) responsible...

Amin S, Hansen A, Mugele H, Simpson L, Marume K, Moore J, et al.
J Appl Physiol (1985)
. 2022 Jun;
133(2):390-402.
PMID: 35708700
Passive hot water immersion (PHWI) provides a peripheral vasculature shear stimulus comparable to low-intensity exercise within the active skeletal muscle, whereas moderate- and high-intensity exercise elicit substantially greater shear rates...

Hansen A, Amin S, Hofstatter F, Mugele H, Simpson L, Gasho C, et al.
Am J Physiol Heart Circ Physiol
. 2022 Mar;
322(5):H844-H856.
PMID: 35333117
Andeans with chronic mountain sickness (CMS) and polycythemia have similar maximal oxygen uptakes to healthy Andeans. Therefore, this study aimed to explore potential adaptations in convective oxygen transport, with a...

PMID: 34245004
Key Points: Humans suffering from polycythaemia undergo multiple circulatory adaptations including changes in blood rheology and structural and functional vascular adaptations to maintain normal blood pressure and vascular shear stresses,...

130(2):283-289.
PMID: 33270516
Spaceflight-associated neuro-ocular syndrome (SANS) involves unilateral or bilateral optic disc edema, widening of the optic nerve sheath, and posterior globe flattening. Owing to posterior globe flattening, it is hypothesized that...

PMID: 33090910
Passive heating has emerged as a therapeutic intervention for the treatment and prevention of cardiovascular disease. Like exercise, heating increases peripheral artery blood flow and shear rate, which is thought...

319(1):H192-H202.
PMID: 32502375
Sympathetic vasoconstriction is mediated by α-adrenergic receptors under resting conditions. During exercise, increased sympathetic nerve activity (SNA) is directed to inactive and active skeletal muscle; however, it is unclear what...
