A novel x-ray diffractometer was installed at the Australian National Beamline Facility at the Photon Factory, Japan, in October 1993. One of the major capabilities of the instrument is high speed high resolution powder diffraction using imaging plate detectors. The diffractometer combines a two circle goniometer and a large cassette in which imaging plates can be loaded covering 320° of 2θ. The diffractometer is enclosed in a large vacuum chamber and can be operated in air, vacuum, or helium. Recently, powder data has been obtained from rutile (TiO2) and NBS Si 640b at wavelengths from 0.62 to 1.9 A(ring) using imaging plates, and has been used to characterize the performance of the instrument. The data has been refined using the Rietveld method and R values of under 2% obtained. The resolution of the system varies from a minimum of about 0.04° to around 0.25° at 2θ angles around 160°, which is the equal of most synchrotron based powder diffractometers, and only slightly worse than that obtained using an analyzer crystal and scintillation detector. Using the imaging plates, 160° of data is simultaneously acquired in an exposure of about 10 min, compared to conventional counter diffractometer scans which routinely exceed 10 hours. © 1995 American Institute of Physics.

One hundred and sixty six patients were questioned by means of a multiple choice questionnaire, to determine their knowledge of peri-operative care, anaesthesia and the role of anaesthetists. In general, knowledge was good, but there were some important misconceptions; in particular, 28.3% of respondents thought that fasting referred to food only, and not to fluid intake. In addition, 47.6% of respondents considered pain to be a necessary part of the healing process and 38.6% believed that it was something that just had to be endured. When forthcoming anaesthesia is discussed, anaesthetists need to ascertain that patients really do understand the language used.

The effects of α-adrenergic drugs on neocortical high voltage spike and wave spindles (HVS), reflecting thalamic oscillation, was investigated in freely moving rats. HVS occurred spontaneously in the awake but immobile animal. Peripheral administration of the α-1 antagonist, prazosin and α-2 agonists, xylazine and clonidine increased the incidence and duration of HVS in a dose-dependent manner. The α-2 antagonist, yohimbine and the tricyclic antidepressants, desipramine and amitriptyline, significantly decreased the incidence of the neocortical HVS. Bilateral microinjections of the α-2 agonists into the nucleus ventralis lateralis area of the thalamus, but not into the hippocampus or corpus callosum, was as effective as peripheral injection of these drugs. Xylazine was most effective in Fischer 344 rats that display high spontaneous rate of HVS and less effective in the Sprague – Dawley and Buffalo strains. The HVS-promoting effect of clonidine was antagonized by prior intrathalamic injection of the α-2 antagonist, yohimbine. The amplitude of the HVS was increased by picomole amounts of unilaterally-injected clonidine. Neurotoxic destruction of the thalamopetal noradrenergic afferents by intracisternal or intrathalamic injection of 6-hydroxydopamine, but not by peripheral administration of DSP-4, increased the incidence of HVS. Importantly, intrathalamic administration of xylazine continued to induce HVS after destroying the thalamic noradrenergic terminals. Following downregulation of the α-2 adrenoceptors by chronic administration (3 weeks) of amitriptylene the incidence of HVS decreased and the effectiveness of intrathalamic xylazine on the induction of HVS was significantly reduced. Based on these findings, we suggest that a major action of α-2 adrenergic drugs on thalamic oscillation may be mediated by postsynaptic α-2 adrenoceptors located on the thalamocortical neurons. We hypothesize that noradrenaline in the thalamus has a dual effect on the relay cells: blocking and promoting thalamic oscillation via α-1 and α-2 receptors, respectively. The final physiological effect is assumed to be a function of the relative density and affinity of these adrenergic receptor subtypes.

One hundred and fifteen patients scheduled for elective Caesarean section under regional anaesthesia were questioned to determine their personality profiles and anxiety state. Positive correlations were found between neuroticism and anxiety scores (p 〈 0.05). Patients with tendencies towards both neuroticism and introversion had higher pre-operative anxiety scores than other personality types (p = 0.015). In general, previous experience did not reduce pre-operative anxiety and personality appeared to be a better predictor of anxiety prior to Caesarean section under regional anaesthesia. Some personality types might benefit from additional support to improve their ability to cope with this stressful event.

Drugs with antidopaminergic properties and those capable of stimulating serotonin release can be responsible for hyperthermia syndromes such as neuroleptic malignant syndrome and serotonin syndrome. Dopamine and serotonin are important neurotransmitters in temperature regulation and it is likely that these reactions result from drug-induced changes in neurotransmitter levels. We describe three cases of drug-induced hyperthermia, discuss their aetiology and management, with both general measures and therapies designed to redress neurotransmitter imbalance.

The bioavailability of iron formed by the corrosion of low-carbon steel (99% Fe) in contact with Red Delicious apples was measured in a rat model using a depletion-repletion experiment. The percentage of ingested iron converted to hemoglobin iron (Conversion Efficiency) was 74, 57, and 56%, respectively, for daily doses of 110, 190, and 285 μg of this iron. (Conversion Efficiency for FeSO4 was 46-50%). When compared with FeSO4= 100, the relative biological value of this iron was found to range from 93–153. Ingestion of one Red Delicious apple that has been exposed to eight large iron nails for 24 hr could provide 10–15 mg iron having good bioavailability.

Abstract Lambda hyperons fromv p and $$\bar v$$ p charged current interactions have been analysed for polarization. A significant polarization is observed for Λ particles in the quasi-elastic region for both types of interactions. Part of this polarization is due to the decay of highly polarized Σ(1385) resonances. The results are compared with simple predictions of the quark parton model.
