Microvascular inflammatory response in the skin
… effects of terbutaline and the NO donor sodium nitroprusside were investigated, as were their effect on the microvascular response to histamine in guinea pig skin. Terbutaline alone showed a small microvascular response interpreted as vasodilatation. The combination of terbutaline and histamine …

Automatic Control Strategies of Mean Arterial Pressure and Cardiac Output. MIMO controllers, PID, internal model control, adaptive model reference, and neural nets are developed to regulate mean arterial pressure and cardiac output using the drugs sodium Nitroprusside and dopamine
… kinds of vasodilating drugs such as Sodium Nitroprusside (SNP), Dopamine (DPM), Nitro-glycerine (NTG), and so on, which can be used to treat postoperative patients, also used for hypertensive emergencies to keep the blood pressure at safety level. A comparative performance of two types of …

The growth-arrest-specific protein gas7 potentiates neuronal differentiation
… the calcium ionophore A23187 or sodium nitroprusside. The ability of gas7 to potentiate neuritogenesis and neuronal differentiation makes it a potential therapeutic target to promote re-establishment of neuronal connections in the injured or diseased brain, such as following stroke.

IL-1β Amplification of Nitric Oxide Production and Its Inhibitory Effects on Glucose Induced Early Growth Response-1 Expression in INS-1 Cells
… glucose induced Egr-1 expression. Sodium nitroprusside dose dependently reduced glucose induced Egr-1 production. The data suggest a strong relationship between IL-1▀ induced nitric oxide production and the reduction of glucose stimulated Egr-1 production. The pathways altered by this …

Microvascular endothelial function in a multi-ethnic group of apparently healthy South African men and women: Implications for testing and the relationship between insulin resistance and microvascular reactivity
… iontophoresis of acetylcholine (ACh) and sodium nitroprusside (SNP) in a multi-ethnic, apparently healthy group to determine whether: 1) there are ethnic differences in microvascular endothelial function and 2) whether the association between microvascular endothelial function and insulin …

Implementação de um sistema embarcado aplicado ao controle de pressão arterial
… infusion of vasodilators drugs, such as sodium nitroprusside (SNP), rapidly decreased blood pressure in most patients, avoiding major problems. Maintaining the desired blood pressure requires constant monitoring of arterial blood pressure and frequently adjusting the drug infusion rate. Manual …

Neurally Released Nitric Oxide does not Oppose Reflex Cholinergic Contraction of Airway Smooth Muscle in Dogs
… smooth muscle. Therefore, we infused sodium nitroprusside to restore pre-L-NAME arterial pressure and repeated the stimuli injections. After baseline nitric oxide levels were restored, the change in airway resistance was not increased to hypertonic saline (A=0.9±.2 cmH20/L/sec) or capsaicin …

Oxidative stress and nitrosative stress, their interaction and implications for bioprocessing
… tension. Adding increasing amounts of sodium nitroprusside (SNP) reduces oxidative stress resulting in an increased production of lysozyme. The use of SNP also showed increased CAT activities, which points towards an interaction between oxidative and nitrosative stress due to the release of …

Integration of signalling in smooth muscle caveolae
… and relaxation in response carbachol and sodium nitroprusside was impaired in caveolae-deficient corpus cavernosum. In the last two papers, I examine the role of caveolae in detrusor function. Disruption of caveolae using desorption of cholesterol was first shown to impair contraction of human …

Integrated modulation of sympathetic tone in the microcirculation by oxygen, adenosine, and nitric oxide
… NO (as judged by arteriolar responses to sodium nitroprusside). The high-O 2 superfusate also did not lead to the generation of reactive oxygen species in the arteriolar wall (as determined by the reduction of tetranitroblue tetrazolium dye). In conclusion, these results suggest that a …

Interactions of islet hormones with acetylcholine and cholecystokinin-octapeptide in the isolated pancreas of normal and diabetic rats
… cholecystokinin octapeptide (CCK-8), sodium nitroprusside (SNIP), 8-Bromo guanosine 3'5' cyclic monophosphate (8-Br cOMP) and nerve stimulation on amylase secretion and intracellular free calcium concentration ([Ca 2 ]) in the isolated pancreas of normal and diabetic rats. The pattern of …

Assessing the Cardiovagal Baroreflex
… Oxford techinique. Bolus injections of sodium nitroprusside followed by phenylephrine HCL are used to decrease and raise blood pressure ~15 mmHg, respectively. The baroreflex control of the cardiac vagal outflow can then be assessed by the relation of the R-R interval to systolic blood …

Effect of vasodilation on the response of muscle protein synthesis to insulin in aging
… insulin as well as the vasodilator, sodium nitroprusside (SNP). Blood flow increased significantly (P<0.001) with the addition of SNP. Using stable isotope methodologies, it was determined that there were also increases in muscle protein anabolism with the addition of SNP. The muscle protein …

Layered Double Hydroxides and the Origins of Life on Earth
… its oriented and non-oriented infrared spectra. Nitroprusside is shown to intercalate into 2:1 Mg:Al LDH with decomposition to form intercalated ferrocyanide and nitrosyl groups of an unidentified nature. The [Ru(CN)6]4- anion is shown to intercalate into layered double hydroxides in the same …
