    Ultrastructural abnormalities in muscular vessels of hyperthyroid patients (1986)

    Notes: Summary an electron microscope study of needle biopsies from the quadriceps muscle was carried out in 11 non=selected patients (ten females and one male), with clinically and laboratory-diagnosed hyperthyroid disease. Alterations of the normal structure of muscle fibres were found in all cases. Changes in capillaries were found in ten patients, and ranged from an increase in basement membrane thickness with reduplication, to total destruction of the capillaries. The importance of the vascular involvement in the muscles of patients with Graves-Basedow disease is stressed.

    Growth and reproduction of Perionyx excavatus (Perr.) (Megascolecidae) as factors in organic waste management (1998)

    Notes: Abstract  The life cycle of Perionyx excavatus has been studied and the potential of this epigeic earthworm species for breaking down and processing organic wastes is well known. Understanding of its optimal environmental requirements is required in order to optimize and accelerate the vermicomposting process. The rates of growth and reproduction of P. excavatus, on a variety of organic wastes, were evaluated in these experiments. The time of maturation and the rates of growth of this species, under various population density pressures and temperatures between 15  °C and 30  °C, were also assessed. Increasing temperatures up to 30  °C accelerated the growth of earthworms and lessened the time to sexual maturity. However, the highest rates of reproduction occurred at 25  °C both in cattle solids and sewage sludge. The mean time to egg hatching decreased and the degree of hatching success increased with increasing temperature. Earthworms grew at similar rates in cattle solids, pig solids and aerobically digested sewage sludge, but the earthworms did not grow well in horse solids and grew only poorly in turkey wastes. The maximum individual growth rates as a function of earthworm population and the maximum earthworm weights as a function of time with a constant food supply at four different temperatures were assessed.

    Production of xylitol from raw wood hydrolysates by Debaryomyces hansenii NRRL Y-7426 (1995)

    Notes: Abstract Xylose solutions were obtained from the hemicellulosic fraction of Eucalyptus globulus by means of sulphuric acid treatments performed under selected operational conditions. The hydrolysates were neutralized, supplemented with nutrients, sterilized and utilised as fermentation media for xylitol production using the yeast Debaryomyces hansenii NRRL Y-7426. Preliminary experiments allowed the adaptation of the strain to the culture media. Further fermentation trials were performed with adapted cells according to an incomplete, factorial design of experiments. Empirical models describing the bioconversion were derived from the experimental results. The effects of three operational variables (nutrient concentration, initial pH and shaking speed) on both xylose consumption and xylitol production rates were described by significant mathematical equations. Additional aspects in relation to the process were also discussed.

    Effect of ACTH on PTH-stimulated bone resorption in vitro (1980)
    Springer

    Keywords: Bone resorption ; PTH ; ACTH ; Basic peptides

    Topics: Biology , Medicine , Physics
    Notes: Summary In vitro demonstration of PTH effects requires hormone concentrations greater than the “physiological” concentrations reported by radio-immunoassay or cytochemical assays. This discrepancy could be the result of binding or destruction of PTH at nonbiologically active sites. In the present study, ACTH was found to have no effect by itself on bone resorption, but addition of ACTH to bone cultures together with low concentrations of PTH resulted in a specific enhancement of PTH-stimulated bone resorption. This effect was not observed when bone resorption was stimulated by PGE2 and 1,25(OH)2D3, and it was blocked by human serum. The effect of ACTH is similar to the enhancement in PTH-stimulated bone resorption by poly-l-lysine [7]. We suggest that the amplification of PTH stimulation was the result of displacement of PTH from nonbiologically active sites, making more PTH available for binding to its biologically active receptor. An alternative explanation for our results was that ACTH prevented degradation of PTH by bone-derived proteolytic enzymes. Thus the sensitivity of bioassays for PTH could be improved by adding ACTH.

    Surgical Findings in Idiopathic Trigeminal Neuropathy Mimicking a Trigeminal Neurinoma (1999)
    Springer

    Notes: Summary  Idiopathic trigeminal neuropathy is a benign disorder where the main clinical feature is facial numbness limited to the territory of one or more divisions of the trigeminal nerve, persisting for a few weeks to several years and in which no underlying disease can be identified. The case of a 37-year-old man with a brief history of sensory and motor trigeminal symptoms who showed magnetic resonance imaging (MRI) findings consistent with a small trigeminal neurinoma is reported. The patient was operated on but no tumour could be found during surgery and a biopsy was taken from the portio major. Pathological diagnosis was chronic non granulomatous inflammatory reaction with areas of coagulation necrosis. Control MRI showed complete resolution of the trigeminal abnormalities. It is concluded that in patients with MRI findings suggestive of a small trigeminal schwannoma, benign idiopathic trigeminal neuropathy should also be considered in the differential diagnosis. A conservative approach with sequential MRI studies may avoid an unnecessary surgical exploration.

    Sequential computerized tomography changes and related final outcome in severe head injury patients (1997)
    Springer
    Acta neurochirurgica 139 (1997), S. 385-391

    Topics: Medicine
    Notes: Summary The authors analysed the serial computerized tomography (CT) findings in a large series of severely head injured patients in order to assess the variability in gross intracranial pathology through the acute posttraumatic period and determine the most common patterns of CT change. A second aim was to compare the prognostic significance of the different CT diagnostic categories used in the study (Traumatic Coma Data Bank CT pathological classification) when gleaned either from the initial (postadmission) or the control CT scans, and determine the extent to which having a second CT scan provides more prognostic information than only one scan. 92 patients (13.3% of the total population) died soon after injury. Of the 587 who survived long enough to have at least one control CT scan 23.6% developed new diffuse brain swelling, and 20.9% new focal mass lesions most of which had to be evacuated. The relative risk for requiring a delayed operation as related to the diagnostic category established by using the initial CT scans was by decreasing order: diffuse injury IV (30.7%), diffuse injury III (30.5%), non evacuated mass (20%), evacuated mass (20.2%), diffuse injury II (12.1%), and diffuse injury I (8.6%). Overall, 51.2% of the patients developed significant CT changes (for worse or better) occurring either spontaneously or following surgery, and their final outcomes were more closely related to the control than to the initial CT diagnoses. In fact, the final outcome was more accurately predicted by using the control CT scans (81.2% of the cases) than by using the initial CT scans (71.5% of the cases only). Since the majority of relevant CT changes developed within 48 hours after injury a pathological categorization made by using an early control CT scan seems to be most useful for prognostic purposes. Prognosis associated with the CT pathological categories used in the study was similar independently of the moment of the acute posttraumatic period at which diagnoses were made.
