Engaging in emotional suppression typically has negative consequences. However, relatively little is known about response-focused emotion regulation processes in dyadic interactions. We hypothesized that interacting with suppressive partners would be more threatening than interacting with expressive partners. To test predictions, two participants independently watched a negatively-valenced vide...

Objective: We herein report two cases of transient cerebral vasoconstriction after carotid artery stenting (CAS).

Prostaglandins are generated by the lungs and released into the circulation. Since inhibitors of prostaglandin synthesis enhance hypoxic pulmonary vasoconstriction, we wondered whether vasodilator prostacyclin was synthesized by the lungs in response to vasoconstriction. To test this hypothesis, we measured vasoconstriction induced by angiotensin II in isolated rat lungs before and after inhibi...

ELEVATION OF THE THERMAL THRESHOLD BY EXPERIMENTALLY INDUCED LOCAL VASOCONSTRICTION

Liver radioembolization is a treatment option for unresectable liver cancers, performed by infusion of 90Y or 166Ho loaded spheres in the hepatic artery. As tumoral cells are mainly perfused via artery unlike lobules, twofold tumor to normal dose ratio commonly obtained. To improve cell killing while preserving co-infusion arterial vasoconstrictor has been proposed but with limited success: buf...

Reversible cerebral vasoconstriction syndrome is a kind of clinicoradiological syndrome reported recently. It is characterized as thunderclap headache and reversible vasoconstriction. However, headache is sometimes absent when reversible vasoconstriction happens. We report a case here admitted because of watershed infarction caused by reversible vasoconstriction without headache when happened i...

Hypoxic vasoconstriction is important for lung ventilation/perfusion matching. The mechanism of hypoxic vasoconstriction remains elusive. Arachidonic acid is released from hypoxic tissues; possibly vasoconstricting arachidonate metabolites are involved in hypoxic pulmonary vasoconstriction. Data are presented that consider (a) lipoxygenase product(s) as "local," which could be involved in the h...

We have previously demonstrated that atrial natriuretic peptide (ANP) completely reverses norepinephrine-induced afferent arteriolar (AA) vasoconstriction. In the present study we characterized the effects of ANP on pressure-induced vasoconstriction of AA. Chronic unilateral hydronephrosis was induced to facilitate direct visualization of the renal microcirculation. Hydronephrotic kidneys were ...
