OBJECTIVE To quantify periodontal disease in rheumatoid arthritis (RA) patients and controls, and to correlate the degree of destruction from periodontal disease and from RA. METHODS Fifty RA patients were matched for age, sex, smoking status, and oral hygiene with 101 controls. Correlations between indices of chronic destruction in periodontal disease(More)
BACKGROUND For the human brain, there are no data available concerning the significance of adenosine and its metabolites as biochemical indicators of cerebral ischemia. Since adenosine may counteract key pathogenetic mechanisms during cerebral ischemia, its sensitivity and specificity as a marker of cerebral ischemia was investigated in relation to(More)
BACKGROUND During experimental cardiac arrest, continuous insufflation of air or oxygen (CIO) through microcannulas inserted into the inner wall of a modified intubation tube and generating a permanent positive intrathoracic pressure, combined with external cardiac massage, has previously been shown to be as effective as intermittent positive pressure(More)
Chronic cerebrovascular disorders are often complicated by additional temporary ischaemic insults, resulting in substantial deterioration of brain energy metabolism. In the present study, chronic limitations of oxygen supply were induced in Wistar rats by 2 weeks of permanent bilateral common carotid artery occlusion (2-vo) to initiate a(More)
UNLABELLED The principle of, "selective shunting" during carotid endarterectomy requires a special concept to monitor neuronal function. The valence of the oxymetric methods, "near-infrared" spectroscopy (NIRS) and conjunctival oxygen tension (pcjO2) was determined with the reference method somatosensory evoked potentials (SEP). METHODS In 41 patients(More)
Nonmelanoma skin cancer (NMSC) is the most frequent type of cancer in humans. Exposure to UV radiation is a major risk factor for NMSC, and oxidative DNA damage, caused either by UV radiation itself or by other agents, may be involved in its induction. Increased sensitivity to oxidative damage and an altered DNA repair capacity (DRC) increase the risk of(More)
