In the present study, the adapted multiple point stimulation (AMPS) method was first applied to median innervated thenar muscles in 22 amyotrophic lateral sclerosis (ALS) patients who did not received any treatment. In all patients, a motor unit number estimate (MUNE) and an average surface-recorded motor unit action potential (S-MUAP) size have been derived even if the denervation was severe; and the results were reproducible. The thenar MUNE was less than the normal lower limit for age in 17 patients, and the mean MUNE (67.1 +/- 90.6) was significantly different from that estimated in control subjects (263.3 +/- 116.8). The mean S-MUAP size in the 22 ALS patients was 352.9 +/- 328.4 microV x ms versus 94.1 +/- 30.3 microV x ms in healthy volunteers. A control AMPS was achieved in 8 patients after 2 and 6 months of a glutamate-release antagonist (riluzole) treatment. The mean loss of motor units, based on control thenar MUNEs realized after 6 months of treatment, was 53%. In conclusion, we propose AMPS as a manageable, reproducible and non-invasive procedure which permits one to quantify peripheral denervation and to appreciate the effectiveness of collateral reinnervation in ALS patients.

Near infrared spectroscopy (NIRS) was used to detect changes in brain oxygenation in five tranquilised calves that were placed on a hypoxic gas mixture (10 per cent O2/90 per cent N2) and hyperoxic gas mixture (30 per cent O2/70 per cent N2) for five minutes at each concentration. A NIRO 500 (Hamamatsu, Japan) was used for the NIRS, with the incident light source and separate detector (optodes) placed on shaved skin on the most dorsal surface of the frontal bone. Sequential arterial blood gas sample analyses provided confirmation of the appropriate change in systemic oxygenation status. By the end of the five-minute-period of breathing 10 per cent oxygen, NIRS of the calf head detected highly significant changes in haemoglobin oxygenation reflective of hypoxaemia, with oxyhaemoglobin decreasing by 23.5 units (P<0.01) and deoxyhaemoglobin increasing by 45.6 units, (P<0.01) from the baseline of breathing room air. Total haemoglobin (oxyhaemoglobin + deoxyhaemoglobin) showed a significant increase of 22.1 units (P<0.05) but there was no significant change in NIRS determined cytochrome aa3 oxygenation. Concomitant blood gas alterations included significant decreases in PaO2 (-27.8 mmHg, P<0.01), haemoglobin saturation (-29.0 per cent, P<0.05), and PaCO2 (-7.8 mmHg, P<0.05) and significantly increased blood pH (0.059, P<0.05). At the end of the five minutes of breathing 30 per cent oxygen NIRS of the calf head detected significantly increased oxyhaemoglobin (13.1 units, P<0.01) and decreased deoxyhaemoglobin (-13.7 units, P<0.05) when compared with baseline breathing of room aim. Total haemoglobin and cytochrome aa3 were unchanged from baseline. The accompanying arterial blood gas changes included significant increases in PaO2 (30.9 mmHg, P<0.05), arterial O2 saturation (11.7 per cent, P<0.05), and significantly decreased pH (-0.026, P<0.05). This study showed that NIRS can be used to continuously and non-invasively detect cerebral oxygenation changes in the live calf in response to both increased and decreased systemic arterial oxygen. Additionally, despite induction of profound hypoxaemia, cytochrome aa3 in the brain did not appear to become reduced. [less ▲]

Le traitement des cancers du col utérin repose sur la radiothérapie et la chirurgie. Le pronostic des formes évoluées a conduit à proposer différentes modalités d’association dont seuls les traitements concomitants ont montré un intérêt. Les associations de radiothérapie et d’un radiosensibilisant n’ont pas apporté, de bénéfice, voire abouti à des résultats inférieurs à ceux de l’irradiation exclusive. L’Hydroxyurée et la Mitomycine C ont été largement testées, seules ou en association, sans qu’elles puissent être retenues comme efficaces. Des associations modernes et des essais récents, il peut être établi que seul le Cisplatine (et peut-être ses dérivés) peut être retenu dans !es propositions thérapeutiques futures. 1998 Elsevier, Paris [less ▲]

Abstract Purpose: To investigate whether whole brain irradiation might be replaced by focalized irradiation after resection of a single brain metastasis in patients where extracranial tumor control is deemed to be obtained. Patients and methods: Twelve patients were introduced in a phase I/II prospective study of conformal postoperative external irradiation after resection of a solitary brain metastasis. The radiation treatment consisted of 50.4 Gy (1.8 Gy per fraction, five fractions per week). The planning target volume consisted of the tumor bed and a 2 cm safety margin. All treatments were optimized with head immobilization, dedicated tomodensitometry and computer assisted three-dimensional treatment planning. Results: The median survival was 7.2 months (range 2.4–50.4 months). Eleven of the 12 patients died. Eight of the 12 patients presented intracranial recurrence and seven died as a consequence of intracranial tumor progression. Conclusions: Focalized external irradiation cannot serve as a reasonable alternative to whole brain radiotherapy (WBRT) even for patients with apparently one single resected brain metastasis. The dogma of ‘one metastasis=multiple metastases' seems to be confirmed. [less ▲]

Calcyphosine is a calcium binding protein discovered in the dog thyroid in 1979. Calcyphosine mRNA and immunoreactivity were detected using Western and Northern blotting in the cerebral cortex, cerebral white matter and cerebellum. Using immunohistochemistry and in situ hybridization, both are present in ependymal cells, choroid plexus cells and several types of astrocytes of the subependymal cerebral layer, the cerebellar Bergmann layer, the retinal ganglion cell layer, the optic nerve and the posterior pituitary. Both are also present in neurons of nasal olfactory mucosa, enteric Auerbach and Meissner plexuses, orthosympathic and spinal cord ganglia as well as in endocrine cells of neural crest origin in the adrenal medulla. Calcyphosine immunoreactive astrocytes were also present mainly in hemispheric cerebral gray and white matter, hemispheric subcortical structures, brain stem and spinal cord. These results show that calcyphosine is a characteristic calcium binding protein of astrocytes and ependymal cells in the central nervous system and of neurons in the peripheral nervous system. This is of interest in view of the importance of calcium regulation in these cells, and since calcyphosine a calcium binding protein phosphorylated by cAMP dependent process, may be an intermediate between cAMP and inositol phosphate cascades [less ▲]

We show that a simple tight binding model with a repulsive potential describes the Peierls distortions in covalent systems and the well-known octet rule. The existence and the intensity of the Peierls distortion is mainly related to the hardness of the repulsive potential as demonstrated both by theoretical calculations and by the experimental systematic analysis of liquid structures. In particular, As is threefold coordinated and Sb is sixfold coordinated in the liquid; the qualitative difference is explained by the ratio of the distortion energy DeltaE to the thermal energy k BT. The As xSb 1-x alloys show continuously varying average coordination numbers showing that the semiconductor-metal transition is continuous with concentration. In addition, we illustrate in the case of liquid Se that, tight binding Monte Carlo simulations are able to describe quantitatively the structure of liquid elements provided the Van der Waals potential is added [less ▲]
