This study tests the hypothesis that the increase in blood PCO2 and associated respiratory acidosis after exhaustive exercise play an important role in stimulating ventilation during post-exercise recovery in fish. Injection of bovine carbonic anhydrase (10 mg kg-1) into the bloodstream of rainbow
Carbonic anhydrase III (CAIII) is abundant in liver, adipocytes, skeletal muscles, but not heart. A cytosolic enzyme that catalyzes conversions between CO2and HCO3-in the regulation of intracellular pH, its physiological role in myocytes is not fully understood.
Increased intracranial pressure (ICP) after stroke can lead to poor outcome and death. Novel treatments to combat ICP rises are needed. The carbonic anhydrase inhibitor acetazolamide diminishes cerebrospinal fluid (CSF) production, reduces ICP in healthy animals, and is beneficial for idiopathic
Mitochondrial dysfunction has been recognized as an early event in Alzheimer's disease (AD) pathology, preceding and inducing neurodegeneration and memory loss. The presence of cytochrome c (CytC) released from the mitochondria into the cytoplasm is often detected after acute or chronic
Ischemic brain and peripheral white blood cells release cytokines, chemokines and other molecules that activate the peripheral white blood cells after stroke. To assess gene expression in these peripheral white blood cells, whole blood was examined using oligonucleotide microarrays in 15 patients at
To assess the effect of latanoprost and fixed combination of dorzolamide/timolol on ocular hemodynamics in patients with primary open-angle glaucoma (POAG).The study examined 34 patients (56 eyes) aged 51 to 69 years (average - 62.4±9.7 years) diagnosed Acetazolamide (ACZ), a potent carbonic anhydrase inhibitor, is known to decrease submaximal exercise tolerance under normoxic and hypoxic conditions. These decrements in performance occur despite the maintenance of O2 consumption and CO2 removal. Because ACZ is a diuretic, it induces a moderate
Experiments were carried out to test the hypothesis that ventilatory and cardiovascular responses to hypercarbia (elevated water P(CO2)) in the tambaqui Colossoma macropomum are stimulated by externally oriented receptors that are sensitive to water CO(2) tension as opposed to water pH.
The aim of the present study was to evaluate the effects of endothelin-l-elicited cardiovascular events on respiratory gas transfer in the freshwater rainbow trout (Oncorhynchus mykiss) and the marine dogfish (Squalus acanthias). In both species, endothelin-1 (666 pmol kg(-1)) caused a rapid (within
BACKGROUND
To investigate the prevalence of depression and anxiety among subjects with self-reported glaucoma and the association between self-reported glaucoma and depression respectively anxiety in a European cohort.
METHODS
A study sample of 14,657 participants aged 35 to 74 years was
OBJECTIVE
Circulating catecholamines and adrenal steroids are significantly increased following traumatic brain injury, and elevations in plasma catecholamines and cortisol portend a poor outcome. We hypothesize that an increase in the generation of reactive oxygen species from the synthesis of
Increases in regional cerebral blood flow have been described in a variety of cerebral pathologic states, including stroke and seizure disorders. The usefulness of technetium-99m-labeled cysteinate dimer as a marker in the measurement of regional cerebral blood flow was tested in five cynomolgus
Zonisamide (ZNS), a sulfonamide antiepileptic drug, is indicated as an adjunct therapy for partial seizure disorders with and without secondary generalization. ZNS has a favorable pharmacokinetic profile because of its rapid absorption and high bioavailability. Its activity is related to the
The National Registry of Drug-induced Ocular Side Effects has accumulated 13 cases of possible major haemopoietic responses from topical ocular chloramphenicol. Over 75 cases of major haemopoietic events from carbonic anhydrase inhibitors are also reviewed. While numerous reports of local ocular
BACKGROUND
We postulated that increasing intracellular chloride concentration ([Cl-]i) in human platelets would potentiate alpha2 adrenergic receptor (A2AR)-mediated platelet aggregation, and that vascular reactivity would also be increased by raising [Cl-]i in blood vessels. We further hypothesized
