Activation of the Parasympathetic Nervous System Is Necessary for Normal Meal-Induced Insulin Secretion in Rhesus Macaques1 [PDF]

open access: yes, 2001
Meal-induced insulin secretion is thought to be regulated primarily by absorbed nutrients and incretin hormones released from the gastrointestinal tract. In addition, the parasympathetic nervous system (PNS) is known to mediate preabsorptive, or cephalic

Hypotensive Anesthesia versus Normotensive Anesthesia during Major Maxillofacial Surgery: A Review of the Literature

open access: yesThe Scientific World Journal, Volume 2015, Issue 1, 2015., 2015
Steady blood pressure within normal limits during surgery is one of the markers of the ideal and skillful anesthesia. Yet, reduced blood pressure is advantageous in some settings because it can contribute to a reduction in overall blood loss and improve the surgical field conditions. Controlled hypotension during anesthesia or hypotensive anesthesia is

Clinical Applications of Remote Ischemic Preconditioning

open access: yesCardiology Research and Practice, Volume 2012, Issue 1, 2012., 2012
Ischemia‐reperfusion injury is a composite of damage accumulated during reduced perfusion of an organ or tissue and the additional insult sustained during reperfusion. Such injury occurs in a wide variety of clinically important syndromes, such as ischemic heart disease and stroke, which are responsible for a high degree of morbidity and mortality ...

A Unique Case of Unilateral Lower Extremity Sparing Systemic Peripheral Gangrene

open access: yesCase Reports in Vascular Medicine, Volume 2012, Issue 1, 2012., 2012
We present here the case of a 70‐year‐old female who developed a systemic peripheral gangrene in both of her upper extremities (all fingers) and her right foot due to a severe septic shock requiring a systemic vasopressor therapy. Interestingly, the patient’s left foot remained spared from gangrenous changes possibly due to a chronic external iliac ...

Nitroglycerin inhibits experimental thrombosis and reocclusion after thrombolysis [PDF]

open access: yes, 1994
Nitroglycerin inhibits platelet aggregation in vitro, but its effect on thrombosis and platelet function in vivo is controversial. This study assessed the effect of nitroglycerin on primary thrombus formation in response to vessel wall injury and ...

Acute and chronic angiotensin hypertension: neural and nonneural components, time course, and dose dependency

open access: yes, 1996
We examined the mechanisms mediating hypertension in conscious rats during acute and chronic infusion of angiotensin II (ANG II) at pressor doses (50, 100, and 200 ng.kg-1.min-1).

The cerebral response to sodium nitroprusside and trimethaphan controlled hypotension [PDF]

open access: yesCanadian Anaesthetists’ Society Journal, 1975
Cette etude avait pour but d’etablir la marge de securite associee a l’emploi d’hypotension controllee en neuro-chirurgie, hypotension produite soit avec du Trimethaphan ou du Nitro-prussiate. Ces agents par leur action sur la resistance vasculaire permettent de diminuer la pression de perfusion cerebrale (C.P.P.) tout en maintenant le flot sanguin ...

Effects of adrenergic blocking agents on plasma free fatty acid concentrations

open access: yes, 1961
To blockade tonic sympathetic influences on FFA (free fatty acids) plasma concentrations, or responses by adipose tissue to administered amines, dogs received Dibenzyline, Dibenamine, ergotamine or trimethaphan. Plasma FFA and glucose in femoral vessels

Modulation of QT interval during autonomic nervous system blockade in humans

open access: yes, 2002
Background— It is thought that the autonomic nervous system modulates QT interval, but traditional autonomic blockade combining propranolol and atropine has produced conflicting results.
