    Notes: Summary Biogel P-30 filtration of plasma from Type 1 (insulin-dependent) diabetic patients and normal subjects in basal state and after an oral glucose load was assayed with a C-terminal (30 K) and a glucagon-like immunoreactivity-cross-reacting antiserum (R8). Up to four immunoreactive peaks of approximate molecular sizes of 〉20,000 (fraction I), 9000 (fraction II), 3500 (fraction III) and 2000 (fraction IV) were detected with the two antisera in both groups. In the basal state, the only significant difference observed between both groups was a higher R8-reactivity in fraction II in the group of diabetic patients, although the R 8 minus 30 K values for this fraction did not show a significant difference between both groups. After glucose the only significant differences were an increase of R8-reactivity in fraction II in both groups (p〈0.01) and a decrease of 30 K-reactivity in fraction III (IRG3500) in normal subjects (p〈0.05). In seven out of 12 diabetic patients, 30 K-reactivity in fraction II (IRG9000) and III (IRG3500) increased above their basal values. The gut-glucagon-like immunoreactivity response to oral glucose (ΔR8-Δ30 K values in fraction II) was similar in both the diabetic and normal subjects. These results indicate that (1) the paradoxical rise in plasma immunoreactive glucagon after oral glucose in diabetic patients may be due to an increase of both IRG3500 and/or IRG9000, (2) the gut-glucagon-like immunoreactivity released during glucose absorption has a molecular weight of approximately 9000, and (3) no differences in plasma gut-glucagonlike immunoreactivity were observed in Type 1 diabetic patients when compared with normal subjects, either in the basal state or after glucose ingestion.

    Notes: Abstract Our aim was to revisit the papers published by Scherer 1933 describing four cases of sporadic olivopontocerebellar atrophy (OPCA) thought to represent the earliest description of striatonigral degeneration. One should note that extrapyramidal rigidity associated with OPCA was then considered a type of cerebellar parkinsonism. Two of Scherer’s four patients had severe parkinsonism masking cerebellar signs. Pathologically both cases displayed marked degeneration of the striatum and nigra and partially developed pontocerebellar atrophy. Cerebellar ataxia was the outstanding feature in the other two, their pathological study showing severe pontocerebellar lesions and incipient striatonigral atrophy. Scherer stated that the severity of parkinsonism in OPCA is not correlated with the degree of cerebellar degeneration but with that of striatum and nigra. We conclude that Scherer gave the first accurate description of striatonigral degeneration. Moreover, his contribution was essential in ruling out the prevalent notion of cerebellar parkinsonism in OPCA.

    Notes: Abstract  This paper reports the effect of the addition of the organic fraction of municipal solid waste at two different rates on the microbiological and biochemical properties of an arid soil after 8 years. The vegetation that appeared spontaneously just after the amendment was still present 8 years later. The organic matter fractions were higher in the amended soil than in the control soil. Amended soil showed higher values of microbial biomass C, soil basal respiration and dehydrogenase activity than control soil, which reached values near to those of the natural soils in the area. The organic amendment had a positive effect on the activity of enzymes related with C, N, P cycles, particularly when the amendment was at the highest dose. This effect could be also observed on the activity of extracted enzymes. The results indicated that the addition of urban waste could be a suitable technique with which to restore soil quality.

    Notes: Abstract  The effect of addition of municipal solid waste (MSW) at different degrees of stabilisation on the biological properties of an arid soil was studied 24 months after application. This included effects on the indigenous soil microflora and soil enzyme activities in the presence and absence of Pythium ultimum. The addition of organic waste (fresh or composted) reduced populations of culturable bacteria and fungi and disease symptoms caused by P. ultimum, and resulted in heavier plants with longer and more extensively branched roots. Addition of organic waste increased the population size of culturable bacteria and fungi, while enzymatic activity of the soil was higher in soil amended with organic matter than in non-amended soil. Populations of biological control agents, such as Trichoderma and fluorescent pseudomonads, were larger in soil amended with organic matter. The addition of urban waste could therefore be a suitable technique with which to restore soil quality by stimulating biological control against plant pathogens such as P. ultimum.

    Relaxation in charge-transfer systems with very large tunnel splitting: A semiclassical stochastic approach (2000)

    Notes: Electron transfer in strongly coupled systems, appropriate to mixed-valence compounds, is studied to explore the competition between electronic coherence and dissipation. A set of stochastic equations is derived for a spin-boson Hamiltonian with large tunneling coupling matrix element (adiabatic regime) and strong system-bath-coupling. The bath dynamics is treated classically while the quantum character of the system is maintained. The bath dynamics is affected by the system dynamics, the effect being included by a mean-field description, valid for the adiabatic regime. Numerical solutions of the stochastic equations are presented and compared with exact quantum mechanical results. The numerical implementation of the method is straightforward and the long-time behavior of the system can be accessed. Analytic equilibrium solutions for the adiabatic regime are obtained, and we find good agreement between the long-time solution of the stochastic equations and these equilibrium solutions. We examine the dependence of the electronic population on the initial preparation of the bath and find that the proportion between oscillation (coherence) and decay (dissipation) is quite sensitive to this initial condition. © 2000 American Institute of Physics.

    Aquagenic keratoderma (2003)

    Notes: Aquagenic keratoderma has been described as a transitory condition involving young females and defined clinically by the appearance of palmar lesions accentuated after immersion in water. According to previous case reports, these lesions are characterized histologically by hyperkeratosis and dilated eccrine ducts.Some aberration in the eccrine ducts has been suggested as a possible pathogenic mechanism. We report a new case in a female adolescent. With regard to the normal aspect of the epidermis in our case, the clinical changes should be ascribed to a structural alteration of the horny layer without any visible microscopy change or functional alteration of the stratum corneum involving the organism in the adolescence period.

    Autoradiographic distribution of [3H]sumatriptan-binding sites in post-mortem human brain (1996)

    Notes: The anatomical distribution of [3H]sumatriptan-binding sites was analysed in brain tissue sections from 11 subjects. Relevant concentrations of [3H]sumatriptan-binding sites were seen in areas such as visual cortex〉locus niger〉globus pallidus〉layers IV-V of the frontal cortex〉subiculum〉entorhinal cortex〉nucleus tractus solitarius〉nucleus trigeminalis caudalis. This distribution of [3H]sumatriptan-binding sites in the human brain shows some differences when compared with that of 5HT1D receptors, confirming that, besides 5HT1D,sumatriptan also binds to 5HT1F receptor subtype. Some species differences are evident between the distribution of [3H]sumatriptan-binding sites in the human brain and that reported for guinea-pig and rat brains, emphasizing that caution is needed in extrapolating experimental data from animals to humans. Furthermore, these data help to explain some of the therapeutic actions of sumatriptan. The remarkable levels of binding found in areas such as nucleus tractus solitarius and nucleus trigeminalis caudalis suggest that in migraine attacks sumatriptan could exert its specific anti-emetic effects and, partly at least, induce analgesia by directly acting over these brain nuclei.

    Notes: Isolated headache as the presenting clinical manifestation of intracranial tumors: a prospective study. Cephalalgia 1994;1'4:270-1. Oslo. ISSN 0333-1024We prospectively studied over two years the incidence of headache as the initial and isolated clinical manifestation of adult patients suffering from intracranial tumors (n = 183). Fifteen patients (8%) exhibited headache as their first and isolated clinical manifestation. Age, sex, neoplasm localization, or pathological diagnosis did not correlate with the presence of headache. Posterior fossa location and hydrocephalus, though not reaching statistical significance, were more frequent in patients who presented with headache as the first symptom. At the moment of diagnosis, 59 (31%) of the patients admitted to headache, though only I out of the 15 patients starting as headache still had this symptom as the only manifestation. From our experience in adults, isolated headache for longer than 10 weeks will only exceptionally be secondary to an intracranial neoplasm.
