    Notes: A patient is presented with the “flag sign” which was associated with episodic malnutrition in an alcoholic. Diminished hair diameter, flating and loss of normal cuticle were found in areas of depigmentation but were sometimes dissociated suggesting different mechanisms within the general terms of “malnutrition”.

    Notes: The management of primary sclerosing cholangitis (PSC) is hindered by incomplete understanding of the pathogenesis of the disease and the lack of good prognostic models. Few large randomized controlled trials of drug therapy have been published. Best practice in the management of PSC is currently based therefore on careful interpretation of the available evidence, close observation of individual patients and clinical experience of the disease. Drug therapy is useful for alleviating symptoms. Ursodeoxycholic acid may slow progression of the disease and reduce the frequency of complications. Consensus is emerging on the issues of screening for the malignant complications of PSC and the indications for liver transplantation are becoming broader and encompassing the earliest stages of cholangiocarcinoma. In view of the rarity of the disease in the general population, large international collaborations to study PSC are necessary to provide clearer answers in areas of uncertainty, and these are now beginning to emerge.

    Notes: [Auszug] Gamma-ray bursts (GRBs) and their afterglows are the most brilliant transient events in the Universe. Both the bursts themselves and their afterglows have been predicted to be visible out to redshifts of z ≈ 20, and therefore to be powerful probes of the early Universe. The burst GRB 000131, ...

    Notes: [Auszug] Gamma-ray bursts (GRBs) divide into two classes: ‘long’, which typically have initial durations of T90 〉 2 s, and ‘short’, with durations of T90 〈 2 s (where T90 is the time to detect 90% of the observed fluence). Long ...

    Notes: [Auszug] THE accompanying photograph (Fig. 1) represents the side of a steel bar. The bar was first marked by a punch in the way shown, and the punch marks were afterwards completely filed out. The side was then polished and the bar pulled in a testing machine beyond the elastic limit of the material. ...

    Description / Table of Contents: Résumé Les insecticides pyrethroïdes ont été utilisés pour lutter contre les pullulations d'araignées rouges. Cette note examine les réponses de Tetranychus urticae Koch et des prédateurs phytoseiidés résistants aux organo-phosphorés, Amblyseius fallacis Garman et Typhlodromus occidentalis Nesbitt, au fenvalerate (pyrethroïde) et à l'azinphosmethyl (organophosphate). Quelques essais avec du carbaryl sont indiqués. Une femelle adulte de T. urticae est placée sur une rondelle de feuille de Phaseolus vulgaris L. pulvérisée dans une tour de Potter. Les résultats sur la mortalité en fonction de la dose obtenus montrent une activité plus rapide du fenvalerate que de l'azinphosmethyl. Les DL50 du fenvalerate (0,056 et 0,051g AI/I) sont les mêmes à 24 et 48 h, tandis que l'azinphosmethyl montre une activité plus lente (DL50 de 0,72 et 0,38g AI/I à 24 et 48 h). La mortalité se partage entre la sortie de la rondelle et la mortalité in situ. Le fenvalerate provoque une plus forte répulsion que l'azinphosmethyl. Contrairement à l'azinphosmethyl le fenvalerate inhibe la production d'oeufs 60% et 20% d'inhibition à DL50 au bout de 24 h par rapport au témoin. Cette inhibition n'est pas permanente. Le carbaryl n'a pas d'effets inhibiteur ou acaricide à 1g AI/l. Les femelles adultes de T. urticae décèlent les résidus de fenvalerate sur les rondelles et pondent leurs oeufs sur les moitiés non traitées ou traitées à l'azinphosmethyl. Les Phytoseiides sont très sensibles aux résidus de fenvalerate. Après consommation d'oeufs traités, A. fallacis est incapable d'éviter des bandes gluantes. T. occidentalis décèle des traitements à 0,00005g AI/l en quittant les lames traitées par les bandes gluantes.
    Notes: Abstract The pyrethroid fenvalerate showed significantly faster activity against adult ♀ two-spotted spider mite Tetranychus urticae Koch c.f. azinphosmethyl using broad bean leaf discs sprayed in a Potter tower. LC50s for fenvalerate were similar at 24 and 48 hr (0.056 and 0.051g AI/1) while LC50s for azinphosmethyl were significantly different at 24 and 48 hr (0.72 and 0.38g AI/1, respectively). Mortality was partitioned to run-off and direct mortality. Fenvalerate showed an increasing contribution to mortality by run-off with increasing concentration. Increasing concentrations of azinphosmethyl had no effect on the proportion of T. urticae running off the discs. Fenvalerate inhibited egg production c.f. azinphosmethyl (60% and 20% inhibition respectively c.f. control after 24hr). The effect was not permanent. Carbaryl showed no acaricidal or inhibitory effects at 1g AI/1. T. urticae detected fenvalerate residues as reflected by choice of oviposition sites on untreated halves of leaf discs c.f. treated halves. Azinphosmethyl had no effect on oviposition preference. Phytoseiid mites were highly sensitive to fenvalerate residues. Predators moved off the test arena into sticky barriers after feeding on fenvalerate-treated eggs or walking on glass slides treated at 0.00005g AI/1.
