Health related quality of life after liver transplantation

To gather information regarding how to best assist liver transplant recipients in improving their self‐care capacity and well‐being, we investigated their total health situation. A retrospective, cross‐sectional survey with up to a 10‐year follow‐up concerning experienced health and quality of life after liver transplantation (LTX) was conducted. The aim of this study was to provide descriptive da

Visual acuity and refractive errors in a suburban Danish population: Inter99 Eye Study.

Purpose: The present study was performed as part of an epidemiological study, the Inter99 Eye Study. The aim of the study was to describe refractive errors and visual acuity (VA) in a suburban Danish population.Methods: The Inter99 Eye Study comprised 970 subjects aged 30–60 years and included a random control group as well as groups at high risk for ischaemic heart disease and diabetes mellitus.

Intracerebral microdialysis of glutamate and aspartate in two vascular territories after aneurysmal subarachnoid hemorrhage

CEREBRAL ISCHEMIA ASSOCIATED with subarachnoid hemorrhage may have severe consequences for neuronal functioning. The excitatory amino acid neurotransmitters glutamate and aspartate have been shown to he of particular importance for ischemia and ischemic neuronal damage. For seven patients who underwent early surgery for ruptured intracranial aneurysms, intracerebral microdialysis of glutamate and

NMDA‐receptor blockers but not NBQX, an AMPA‐receptor antagonist, inhibit spreading depression in the rat brain

The effect of different glutamate‐receptor antagonists on the induction of cortical spreading depression of Leao and of cortical anoxic membrane depolarization were investigated in the anaesthetized rat. Spreading depression (SD), elicited by mechanical stimulation of the cortical surface, was inhibited by the non‐competitive N‐methyl‐d‐aspartate (NMDA)‐receptor blocker, (±)‐5‐methyl‐10,11‐dihydro

Lack of protection by the N-methyl-D-asparate receptor blocker dizocilpine (MK-801) after transient severe cerebral ischemia in the rat

Glutamate is an important factor in the mechanisms of neuronal damage following cerebral ischemia. Blockade of one type of glutamate receptor, the N-methyl-D-aspartate (NMDA) receptor, decreases brain infarct size in experimental models of permanent focal ischemia, but protection in models of transient reversible ischemia is ambiguous. We investigated the effect of the noncompetitive NMDA receptor

Extracellular levels of quinolinic acid are moderately increased in rat neostriatum following severe insulin-induced hypoglycaemia

Extracellular concentrations of the brain metabolite quinolinic acid, an endogenous excitotoxin, were monitored by microdialysis in rat neostriatum and hippocampus/cortex during and following a 30-min period of insulin-induced hypoglycaemia. During hypoglycaemia-induced isoelectricity, extracellular levels of quinolinic acid in the striatum (basal value, 1.1 ± 0.3 pmol per 30-μl fraction) were ele

Mitochondrial permeability transition induced DNA-fragmentation in the rat hippocampus following hypoglycemia

In the present study the time-course of DNA fragmentation following insulin-induced hypoglycemia was examined. In situ localization of DNA breaks were studied by the terminal deoxynucleotidyl transferase-mediated biotin- deoxyuridine triphosphate nick-end labelling method, and the temporal profile of DNA-fragmentation by agarose gel electrophoresis. Cell nuclei displayed terminal deoxynucleotidyl

Influence of MK-801 on brain extracellular calcium and potassium activities in severe hypoglycemia

The purpose of the present study was to examine the effect of blockade of N-methyl-D-aspartate (NMDA) receptors on the depolarization associated with severe hypoglycemia, which is commonly preceded by one or a few transient depolarizations reminiscent of cortical spreading depression (CSD). In the cerebral cortices of rats [K+](e) and [Ca2+](e) were measured with ion-selective microelectrodes. NMD

Cyclic AMP Concentrations in Rat Neocortex and Hippocampus During and Following Incomplete Ischemia : Effects of Central Noradrenergic Neurons, Prostaglandins, and Adenosine

Abstract: The concentrations of cyclic AMP, noradrenaline, glycogen, glucose, lactate, pyruvate, labile phosphate compounds, and free fatty acids were investigated in the rat neocortex and hippocampus during and following cerebral ischemia. An incomplete ischemia of 5 and 15 min duration was induced by bilateral carotid clamping combined with hypotension. The postischemic events were studied after

The dentate gyrus in hypoglycemia : Pathology implicating excititoxin-mediated neuronal necrosis

A detailed light- and electron-microscopic study of the damage to the rat dentate gyrus in hypoglycemia was undertaken, in view of the previously advanced hypothesis that hypoglycemic nerve cell injury is mediated by a released neurotoxin. The distribution of neuronal necrosis showed a relationship to the subarachnoid cisterns. Electron microscopy of the dentate granule cells and their apical dend

Models for studying long‐term recovery following forebrain ischemia in the rat. 2. A 2‐vessel occlusion model

ABSTRACT— A model is described in which transient ischemia is induced in rats anaesthetized with N2O:O2 (70:30) by bilateral carotid artery clamping combined with a lowering of mean arterial blood pressure to 50 mm Hg, the latter being achieved by bleeding, or by bleeding supplemented with administration of trimetaphan or phentolamine. By the use of intubation, muscle paralysis with suxamethonium

Lesions of the glutamatergic cortico-striatal projections in the rat ameliorate hypoglycemic brain damage in the striatum

Unilateral ablations of the motor cortex were performed on rats. One to two weeks following the ablation they were subjected to 30 min of reversible insulin-induced hypoglycemic coma. The levels of glutamate, aspartate, γ-aminobutyric acid (GABA), taurine, adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP) and phosphocreatine (PCr) were determined in frozen ti

Iceland Should Replace Its Central Bank with a Currency Board.

In this contribution, we discuss the menu of policy regimes available for Iceland. Each regime is evaluated against the characteristics of the Icelandic economy. We start with a short description of the Icelandic economy. We then examine the costs and benefts of alternative monetary regimes. We conclude that no regime Iceland has tried since attaining full sovereignty in 1918 has provided economicIn this contribution, we discuss the menu of policy regimes available for Iceland.
