The haemodynamic response to critical care intubation is influenced by the use of sedation and relaxant drugs and the activation of the vagal reflex. It has been hypothesized that different disease states may have a contrasting effect on the cardiovascular response to vagal stimulation. Our objective was to determine whether ...

OBJECTIVES:: Enhanced sympathetic neurotransmission contributes to hypertension in the spontaneously hypertensive rat (SHR). We recently reported a method for studying sympathetic neurotransmission in pressurized small arteries, demonstrating a major role of adenosine triphosphate (ATP) as a sympathetic neurotransmitter under these physiological conditions. We have now used this methodology to assess ...

Sclerosteosis (OMIM 269500) is a progressive, autosomal recessive, sclerosing bone disorder with a well-defined phenotype. This phenotype is correlated with a deficiency in the protein product sclerostin, leading to bony overgrowth from the loss of inhibition of osteocyte function. Calvarial overgrowth can lead to cranial nerve palsies, visual impairment, and ...

Resistant hypertension is frequently encountered and remains challenging in everyday clinical practice despite the availability of numerous effective antihypertensive drugs. Existing limitations in drug therapy renders renal nerve ablation (RNA) an attractive alternative for the management of resistant hypertension. RNA has been proven so far both effective and safe in ...

Endovascular renal nerve ablation has been developed to treat resistant hypertension. In addition to lowering efferent renal sympathetic activation, the intervention may attenuate central sympathetic outflow through decreased renal afferent nerve traffic, as evidenced by a recent case report. We tested the hypothesis in 12 nonpreselected patients with difficult-to-control hypertension ...

Therapeutic interventions aimed at reducing high blood pressure still encompass a number of difficulties and limitations. This is the case particularly in resistant hypertension, i.e. a condition characterized by a very high cardiovascular risk. Carotid baroreceptor stimulation and renal sympathetic nerves ablation represent new approaches in the treatment of this ...

Papilledema has long been associated with elevated intracranial pressure. Classically, tumors, idiopathic intracranial hypertension, and obstructive hydrocephalus have led to an increase in intracranial pressure causing optic nerve head edema and observable optic nerve swelling. Recent reports describe astronauts returning from prolonged space flight on the International Space Station with ...

The vast majority of individuals with alcohol problems in the United States and elsewhere do not seek help. One policy response has been to encourage institutions such as criminal justice and social welfare systems to mandate treatment for individuals with alcohol problems (Addiction, 1997;92:1133). However, informal pressures to drink less ...

Reactive oxygen species enhance or impair autoregulation. Because superoxide is a vasoconstrictor, we tested the hypothesis that stretch generates superoxide that mediates myogenic responses. Increasing perfusion pressure of mouse isolated perfused renal afferent arterioles from 40 to 80 mm Hg reduced their diameter by 13.3±1.8% (P<0.001) and increased reactive oxygen ...
