Attenuation of isoproterenol-mediated vasodilatation in blacks [PDF]
The mechanism of enhanced vascular reactivity in young blacks, which may play a part in the development of hypertension, has not been defined. To determine the contribution of blunted vasodilatation mediated by ß2-adrenergic receptors to this phenomenon,

Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

Amino acids induce renal vasodilatation in isolated perfused kidney: coupling to oxidative metabolism [PDF]
Renal vasodilatation regularly accompanies protein feeding and amino acid infusions, but the mechanism is unknown. The effects of several different amino acids on renal hemodynamics were studied in the isolated rat kidney, perfused with glucose as the ...

Abstract Blood flow restriction (BFR) has been identified as a potential countermeasure to mitigate physiological deconditioning during spaceflight. Guidelines recommend that tourniquet pressure be prescribed relative to limb occlusion pressure (LOP); however, it is unclear whether body tilting or reduced gravity analogues influence LOP.

Involvement of trigeminal spinal nucleus in parasympathetic reflex vasodilatation in cat lower lip [PDF]
We examined whether the trigeminal spinal nucleus (Vsp) forms part of the central mechanism by which electrical stimulation of the central cut end of the lingual nerve (LN) evokes parasympathetic reflex vasodilatation in the lower lip in artificially ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Genetische Suppression endothelialer KCa3.1 und KCa2.3 unterdrückt die EDHF-vermittelte Vasodilatation und erzeugt Hypertonie [PDF]
Das Endothel nimmt Einfluss auf den Tonus der glatten Gefäßmuskulatur und ist somit wichtig für die adäquate Regulation der Gewebeperfusion und des systemischen Blutdrucks.

Effect of Medication on Microvascular Vasodilatation in Patients with Systemic Lupus Erythematosus [PDF]
The aim of this study was to investigate the microvascular responses in the skin, to local heat, iontophoretically administered acetylcholine and to sodium nitroprusside in relation to cardiovascular damage in patients with systemic lupus erythematosus ...

Abstract Renal arterial infusion of tempol (RAT) at the onset of Gram‐negative sepsis can prevent sepsis‐induced medullary tissue hypoxia and acute kidney injury (AKI). However, it is not known whether treatment with tempol at a clinically relevant time point of sepsis is similarly effective. Thus, we examined whether tempol can reverse renal medullary
