A Free-breathing fMRI Method to Study Human Olfactory Function

Abstract:
Jane Buckle presents the results of a randomised, double-blind trial of two essential oils of two different species of lavender, topically applied on post-cardiotomy patients. The emotional and behavioural stress levels of 28 patients were evaluated pre- and post-treatment on two consecutive days. The therapeutic effects of the two lavenders appeared to be different: one was almost twice as effective as the other, thereby disproving the hypothesis that aromatherapy, using topical application of essential oils, is effective purely because of touch, massage or placebo.

Adrenergic Agonists: Therapeutic Classification
Vasopressor or pressor agents: They increase blood pressure and function as cardiac stimulants. Examples include endogenous catecholamines (norepinephrine and dopamine) and synthetic agents (phenylephrine).
Bronchodilators: β2-agonists can relax bronchial muscles and widen airways. They are commonly used for treating obstructive pulmonary...
Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
