    Size distribution of a metallic polydispersion through capacitive measurements in a sedimentation experiment (2001)

    Notes: We present a simple experimental technique to determine size distributions of metallic polydispersions. The particles are first suspended in a viscous fluid-like glycerol and then their sedimentation is followed by measuring the effective dielectric constant in a cylindrical cell at a fixed frequency. Thereafter, an inversion procedure of the data, based on the Maxwell–Garnett effective medium theory and Stokes law, is used to directly obtain the size distribution. The technique is applied to three different stainless steel dispersions and compares very well with a traditional sizing method based in microphotography. © 2001 American Institute of Physics.

    TRANSGLUTAMINASE CROSS-LINKING OF BOVINE CARDIAC MYOFIBRILLAR PROTEINS AND ITS EFFECT ON PROTEIN GELATION (2001)

    Notes: Myofibrillar protein concentrate (MPC) was prepared from beef heart muscle (3 or 5% protein), and the sols were incubated with 0.5 unit/mL transglutaminase (TGase) at 5 and 15C for 0, 0.5, 2, 5, 10, and 15 h to determine the enzyme effect on MPC gelation. After each incubation time, dynamic gelling tests, differential scanning calorimetry, and electrophoresis (for sols and gels) were performed on all samples. MPC samples with TGase had greater (P〈0.05) gelling ability, regardless of preincubation (time and temperature), showing increases in storage modulus (G') from 600–900 Pa (control) to 1700–2000 (treated) at 70C. The results suggest that the gelation-enhancing effect by TGase was attributed to cross-linking of myosin, and that TGase can be used to improve the binding ability of beef heart myofibrillar proteins in restructured meats.

    Genetic introgression between wild and stocked brown trout in the Douro River basin, Spain (2001)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 59 (2001), S. 0

    Notes: The genetic diversity of Spanish brown trout is currently threatened by stocking with exogenous brown trout from Central and Northern Europe. In the Douro River basin 25% of the analysed populations in the present study showed introgression by genes of hatchery origin. The mean introgression estimated by the single locus approach (S) varied from 0 to 22% among populations, with a mean value of 3%. The hatchery allele markers were absent in populations where stocking ceased in 1993. However, the introgression effect was observed in all populations stocked until 1998. It seems that cessation of stocking is a good measure for restoring native populations. A thorough review of published and present data of genetic interactions between wild and stocked brown trout in Spanish rivers indicates different levels of introgression between basins. The absence of a clear geographical pattern in the introgression level suggests that ecological interactions and local stocking programmes may play an important role in stocking success. Finally, several guidelines are provided for conservation and management of native brown trout populations in Spanish rivers.

    Notes: Abstract  The phenolic composition of red and white wines from four Spanish Appellations of Origin (official classification of Spanish wines) was investigated. Different hydroxybenzoic and hydroxycinnamic acids, catechins, procyanidins, alcohols, stilbenes and flavonols were identified. Additionally, the ketone 2,3-dihydroxy-1-guaiacylpropan-1-one was identified for the first time in red wines aged in oak barrels. The concentration of most of the phenolic compounds quantified was higher in red wines than in white wines, as would be expected from the different methods of vinification and the grape varieties used. These differences could also contribute to differences in the antioxidant ability of these wines. The multivariate analysis applied to the phenolic compounds quantified allowed the relationships among these compounds to be examined and the origin of the wines to be distinguished.

    Notes: Abstract  Chloroanisoles [2,4-dichloroanisole, 2,4,6-trichloroanisole (TCA), 2,3,4,6-tetrachloroanisole and pentachloroanisole], chlorophenols [2,4,6-trichlorophenol, 2,3,4,6-tetrachlorophenol and pentachlorophenol (PCP)] and guaiacol were detected in red and white cork-tainted bottled wines. These compounds were also found in the cork stoppers from those bottles. A significant correlation was found between TCA in wines and TCA in cork stoppers, and between TCA in wine and intensity of cork taint. At low levels of TCA, the presence of guaiacol or PCP were also found to influence in cork taint.

    Notes: Summary ¶ Objective. We analyse the clinical aspects, results and reliability of posteroventral pallidotomy (PVP) carried out as treatment for the principal symptoms and treatment induced complications in patients with Parkinson's disease (PD).  Patients and Methods. Between August 1995–January 1998, 17 patients with PD were treated surgically, 13 patients with PVP. A pre- and post-surgical clinical evaluation was carried out. Riechert's Stereotactic System (MHT, Freiburg, Germany) was used. Ventriculography under stereotactic conditions was used in the PVP procedures, Laitinen's co-ordinates as anatomical target, and electrical stimulation for physiological determination. 3–4 radiofrequency lesions were made at 83°C for 20″. The mean age was 60±10.8 years, ages ranging from 45–79 years. 8 (60.5%) of the patients were male. The cardinal symptoms of the series were bradykinesia and rigidity. The duration of the illness ranged from 8.6±3.7 years with a range of 4–15 years. 7 (53.8%) presented with a duration of 10 years or more. 6 (46,2%) of the patients underwent left PVP, the remaining 7 (53.8%) right PVP. Only one patient received treatment with right PVP and ipsilateral thalamotomy in the same surgical procedure. The mean post-surgical follow up was 16±7 months, with a range of 2 to 26 months.  Results. An up to date evaluation was carried out on all patients showing significant changes after PVP in UPDRS motor (P〈0.005), complete rigidity relief (P〈0.005), bradykinesia relief (P〈0.005) and complete tremor relief (P〈0.005). An important improvement in contralateral dyskinesia was noted after PVP. A subjective evaluation of the results showed excellent results in 4 (30.8%) patients, good in 6 (46.2%) and fair in 3 (23%). No significant correlation was found between age and duration of illness (P=0.7). Two patients suffered slight side effects, one patient with worsening of hypophonia whilst the other suffered subjective visual impairment controlled by normal post operative ophthalmological examinations. There was no peri-operative mortality.  Conclusion. PVP is considered a safe and effective surgical method for the treatment of both the principal symptoms of PD and the complications of DOPA medication.

    Postraumatic intracranial hematomas in infancy (2000)

    Notes: Abstract  Objects: The objective of this study is to analyze some of the epidemiological aspects in patients with post-traumatic intracranial hematomas (post-traumatic ICH) in infancy. These patients were treated at the Hospital Infantil Municipal de Córdoba, Argentina, between April 1980 and April 1996. Methods: A retrospective descriptive analysis was conducted on the 113 case histories of children with post-traumatic ICH, all of whom required surgical intervention during this period. Relevant information such as age, sex, mechanism of injury causing craniocerebral trauma (CCT), and data on clinical presentation on admission, diagnosis, morbidity and mortality rates were collected. Conclusions: The series revealed a greater incidence of post-traumatic ICH in boys (73.5%), whose average age was 6 years 5 months ± 4 years 10 months (range 1 day to 15 years). Fifty-three percent of the girls suffered post-traumatic ICH before the age of 3, while 54% of the children were 7 years of age or older (P〈0.05). Falls were the most frequent mechanism of injury causing CCT (36.3%), followed by vehicle accidents (33.6%) and unknown causes (15.9%), the latter mainly in children under 3 years old (31%). The most frequent symptoms were vomiting (58.6%), loss of consciousness (47.1%) and headaches (24.1%). Of all these children, 93.8% presented signs and symptoms at the time of hospital admission, alterations in the level of consciousness (66%), vomiting (47.2%) and headaches (26.4%) being among the most frequent. The hemorrhagic complications observed in the 113 patients took the form of extradural hematomas (EDH) in 75 (66.4%), of subdural hematomas (SDH) in 35 (31.0%), of hemorrhagic contusions (Hc) in 19 (16.8%), and of intracerebral hematomas (Ich) in 11 (9.7%). In 13 patients the site of the hematoma was the posterior cranial fossa (11.5%), and 22.1% of patients presented more than one type of hemorrhagic complication. Morbidity rates were 9.7% and mortality rates 17.7%.
