ISSN: 0942-0940Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Summary The diagnostic and prognostic values of quantitative isotope ventriculography (QIV), lumbar isotope cisternography (LIC), pneumoencephalography (PEG), and continuous intraventricular pressure recording (CIP) were assessed on the basis of the clinical course in 160 patients suspected of having acquired hydrocephalus. The diagnostic value of a given method is defined as its reliability in the diagnosis of hydrocephalus. The reliability in the selection of hydrocephalic patients who will improve on shunt operation is designated as the prognostic value of the method concerned. As the diagnoses are based on isotopic procedures, the diagnostic values of these procedures cannot be assessed. QIV is of greater prognostic value than the other methods of examination. The presence of plateau waves in CIP is a rare, but prognostically valuable sign. The prognostic value of B waves is also good, whereas their diagnostic value is slight. Both from diagnostic and prognostic points of view, PEG is of less value in communicating hydrocephalus on account of the many false findings.Type of Medium: Electronic ResourceURL: -

ISSN: 0942-0940Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Summary By quantitative isotope ventriculography (QIV), the formation rate of albumin in the ventricular system (FRalb) was determined in 14 hydrocephalic and 14 nonhydrocephalic patients. The FRalb was significantly reduced in the patients with acquired hydrocephalus. By a comparison of the mean formation rate of albumin (MFRalb) and the mean absorption rate of albumin (MARalb), a significant biological difference in the two groups of patients was demonstrated.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7682Source: AIP Digital ArchiveTopics: PhysicsNotes: A new algorithm for analyzing the evolution of patterns of spiral and target waves in large aspect ratio chemical systems is introduced. The algorithm does not depend on finding the spiral tip but locates the center of the pattern by a new concept, called the spiral focus, which is defined by the evolutes of the actual spiral or target wave. With the use of Gaussian smoothing, a robust method is developed that permits the identification of targets and spirals foci independently of the wave profile. Examples of an analysis of long image sequences from experiments with the Belousov–Zhabotinsky reaction catalyzed by ruthenium-tris-bipyridyl are presented. Moving target and spiral foci are found, and the speed and direction of movement of single as well as double spiral foci are investigated. For the experiments analyzed in this paper it is found that the movement of a focus correlates with foci in the immediate neighborhood independently of how they were created. © 2002 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1471-4159Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Abstract : To study the effects of creatine (Cr) on brain energy metabolism and on hypoxia-induced seizures, 5-to 30-day-old rabbit pups were given subcutaneous Cr (3 g/kg) for 3 days before exposure to 4% O2 for 8 min. In saline-treated controls, hypoxic seizures were most frequent at 15 days (80% of pups) and 20 days (60%) of age. Seizures were prevented at 15 days and reduced 60% at 20 days in Cr-treated pups. In surface coil-localized brain 31P nuclear magnetic resonance spectra, with signal from both cerebral gray (GM) and white (WM) matter, the phosphocreatine (PCr)/nucleoside triphosphate (NTP) ratio doubled between 5 and 30 days of age in controls. In all Cr-injected pups, brain PCr/NTP increased to values seen in 30-day-old controls. When spectra were acquired in predominantly GM and WM slices in vivo, the PCr/NTP ratio was very low in GM at 5 days but reached adult levels by 15 days in controls. In WM, the ratio increased steadily from 5 to 30 days of age. In Cr-injected pups, PCr/NTP increased to mature levels in WM and in GM at all ages. In conclusion, hypoxic seizures occur midway in the time course of brain PCr/NTP increase in rabbit pups as previously described in rat pups. In both altricial pups, systemic Cr increases brain PCr/NTP ratio and prevents hypoxic seizures. These results suggest that mature levels of PCr and/or Cr in brain limit EEG activation either directly or indirectly by preventing hypoxic metabolic changes.Type of Medium: Electronic ResourceURL: -

Published 1981Staff ViewISSN: 1468-2982Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Clinical findings of four female members from one family with familial hemiplegic migraine are briefly summarized. Cerebral blood flow (CBF) studies using the xenon 133 inhalation method were carried out during and between hemiplegic attacks in two of the family members. CBF was significantly lower over the affected hemisphere during attacks, while equal flow on both sides was seen in headache free periods. The findings indicate that cerebral perfusion is altered, but not necessarily decreased during attacks of familial hemiplegic migraine.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: A new method for imaging the probe tip of an atomic force microscope cantilever by the atomic force microscope itself (self-imaging) is presented. The self-imaging is accomplished by scanning the probe tip across a sharper tip on the surface. By using a pyramidal probe tip with a very well-defined aspect ratio, this technique provides an excellent z-calibration standard for the atomic force microscope.Type of Medium: Electronic ResourceURL: -

Published 1997Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: The capability of misfit dislocations to generate nanostructures in the bulk of Si1−xGex/Si heteroepitaxial systems is demonstrated. It is shown that dislocation slip originating from compositionally graded Si1−xGex layers can produce a range of low-dimensional structures including nanowires, nanodots, and mosaic superlattices. Formation of the nanostructures is achieved in parallel processing, through a simple two-step cycle which includes growth of layered planar structures and postgrowth annealing. © 1997 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Measurements were performed in the supine, sitting and standing positions on each day. Arterial oxygen saturation was significantly higher during sitting and standing on days 1 and 4 after operation compared with the supine position (p 〈 0.05). These results give further evidence for the benefits of patient mobilisation after major surgery.Type of Medium: Electronic ResourceURL: -

Published 1987Staff ViewISSN: 1365-2044Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Ventilatory sensitivity to carbon dioxide was measured in six healthy volunteers before, and at various times up to 20 hours after, administration of epidural buprenorphine 0.15 mg with a modified Read rebreathing technique. The carbon dioxide response curves were depressed in a time-dependent, prolonged and biphasic manner. Significant depression was seen in the intercept values at an end tidal carbon dioxide of 7.2 kPa. for mouth occlusion pressure (p 〈 0.01), tidal volume (p 〈 0.05) and minute ventilation (p 〈 0.05). A significant reduction of slope was obtained only for minute ventilation. Linear regression of respiratory rate changes during carbon dioxide stimulation, did not reach statistical significance. In conclusion, these data indicate that epidural buprenorphine, despite a high lipid solubility, causes respiratory depression to the same extent as epidural morphine. Surveillance of patients who receive epidural buprenorphine for postoperative pain relief is necessary.Type of Medium: Electronic ResourceURL: -

ISSN: 1095-8649Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyNotes: Transfer of rainbow trout from fresh water to 20‰ sea water decreased dorsal aortic Po2 from 90 to 60 mmHg within 1 h. Arterial Po2 was depressed for 24 h before it returned to control values. The internal hypoxia rapidly reduced the red cell nucleoside triphosphate content, suggesting prompt regulation of blood O2 affinity. The extracellular acid-base status changed towards a small mixed metabolic and respiratory acidosis.Type of Medium: Electronic ResourceURL:
