    Notes: Summary Pain resulting from photodynamic therapy (PDT) of skin cancer was investigated. The study included 69 lesions (60 patients) with different types of skin tumours or precursors. Protoporphyrin IX, which is produced by the topical application of δ-aminolevulinic acid, was used as a photosensitizing agent. Twenty-three of the lesions (19 patients) were examined with a fluorescence imaging system which demarcates the tumour area from the healthy skin and visualizes the contrast between the fluorescence from healthy skin and that from the tumour. EMLA® is used on all patients as part of our routine PDT protocol but despite this the major side-effect of PDT is pain during treatment. There is a large variation in pain intensity experienced by the patients, as measured by a visual analogue scale (VAS). Patients with actinic keratoses experienced more pain than those with Bowen's disease or basal cell carcinoma. The mean VAS score was higher when treating lesions located on the head than when treating lesions on the torso or the extremities. Also, treatment of large skin areas resulted in more pain than treatment of small areas, and men experienced more pain than women. The pain experienced by the patients did not correlate with treatment dose, Fitzpatrick skin type, age or fluorescence intensity.

    Notes: The purpose of this paper is to present a system for describing and indexing patterns of communication at the relational level, primarily in dyadic systems. Relational communication refers to the control aspects of message exchanges that define an interactor's relationships with others. The reciprocal definition of each individual's role at a given moment in the interaction is reflected in the relative control each individual has and/or is given by the other individual. The control-defining aspects of communication, rather than other information such communication may convey, is the focus of the coding system to be described. Further, the analysis deals with sequences of messages rather than individual messages, and attempts to index the control dimensions of those messages according to their similarity or difference. While previous interaction analysis techniques have been predominantly monadic in nature, i.e., single-message coding schemes, the present approach is based on a systems level of analysis./〉

    Notes: The pelagic and gregarious, low Arctic harp seal (Phoca groenlandica) is the most common seal species in most refuse faunas from coastal hunter-gatherer sites dating from the late Atlantic to the early Subboreal period (ca. 4000-2000 cal B. C.) in the Baltic Sea. Our main objective was to examine the migration contra breeding population hypotheses regarding the Baltic harp seals. Analyses of epiphyseal fusion data and osteometry of archeological harp seal remains from 25 dwelling-sites suggest that a local breeding population established itself in the early Subboreal period. In the Middle Neolithic the rookery possibly was situated in the Baltic proper, south of Aland and west of Gotland. The mean adult size of the Baltic harp seals decreased, suggesting minimal genetic exchange with the north Atlantic Ocean population. Genetic drift, interspecific competition, and over-hunting by humans are all factors likely to have contributed to the eventual extinction of harp seals in the Baltic Sea.

    Notes: The ability to regulate transgene expression will be crucial for development of gene therapy to the brain. The most commonly used systems are based on a transactivator in combination with a drug, e.g. the tetracycline-regulated system. Here we describe a different method of transgene regulation by the use of the human glial fibrillary acidic protein (GFAP) promoter. We constructed a lentiviral vector that directs transgene expression to astrocytes. Using toxin-induced lesions we investigated to what extent transgene expression could be regulated in accordance with the activation of the endogenous GFAP gene. In animals receiving excitotoxic lesions of the striatum we detected an eightfold increase of green fluorescent protein (GFP)-expressing cells. The vast majority of these cells did not divide, suggesting that the transgene was indeed regulated in a similar fashion as the endogenous GFAP gene. This finding will lead to the development of lentiviral vectors with autoregulatory capacities that may be very useful for gene therapy to the brain.

    Notes: The uptake of chlorhexidine to hydroxyapatite was studied in vitro. Data were obtained indicating a multilayer adsorption at high concentration (〉0.02 %) and a stable monolayer at lower concentrations. The clinical significance of such a monolayer in plaque prevention is discussed. Adorption of chlorhexidine did not affect the acid solubility of hydroxyapatite.
