Only registered users can translate articles

Twenty-three subjects with noninsulin-dependent diabetes mellitus (NIDDM) and 23 age- and sex-matched controls were tested for sympathetic denervation of the iris dilator by comparing the mydriatic effect of the combination of 1% phenylephrine and 1% tropicamide with that of 1% tropicamide alone.

Substance P in the human iris: possible involvement in echothiophate-induced miosis in cluster headache.

Only registered users can translate articles

Substance P-like immunoreactivity (SP-LI) was measured by radioimmunoassay in iris, choroid, and retina obtained from men after death. Although present in different amounts, SP-LI, eluting as authentic SP or SP sulfoxide in the high-performance liquid chromatography system, was found in the three

IRIS study: a phase II study of the steroid sulfatase inhibitor Irosustat when added to an aromatase inhibitor in ER-positive breast cancer patients.

Only registered users can translate articles

OBJECTIVE Irosustat is a first-generation, orally active, irreversible steroid sulfatase inhibitor. We performed a multicentre, open label phase II trial of the addition of Irosustat to a first-line aromatase inhibitor (AI) in patients with advanced BC to evaluate the safety of the combination and

The enhanced ciliospinal reflex in asymptomatic patients with cluster headache is due to preganglionic sympathetic mechanisms.

Only registered users can translate articles

An amplified ciliospinal reflex response has been documented in patients with cluster headache, lacking a Horner-like syndrome. The mechanism is unknown. Tentatively, it may be due to an increased release of monoamines from post-ganglionic sympathetic nerve endings or an increased density of

Adrenergic supersensitivity of the pupil in idiopathic headache.

Only registered users can translate articles

In idiopathic headache (IH) sufferers, phenylephrine and fenfluramine induce a pupillary dilatation respectively greater and lesser than in controls. The difference may be due to a supersensitivity of the iris alpha adrenoceptors caused by a deficiency of noradrenaline in the iris adrenergic nerve

Substance P theory: a unique focus on the painful and painless phenomena of cluster headache.

Only registered users can translate articles
