This study was undertaken to evaluate the role of transcytosis as a bulk transfer mechanism for the passage of albumin from blood to tissue. Isolated rat lungs were continuously weighed and perfused with an albumin-serum buffer solution under strictly controlled hemodynamic conditions, which allowed measurements of microvascular pressure and of the capillary filtration coefficient (LpS). With the

Den yttersta länken bakom all form av samhällsutveckling är den enskilda människan, som mot bakgrund av sina värderingar och attityder fattar beslut om att handla på ett visst sätt och inte ett annat. I detta avsnitt kommer fokus för analysen av drivkrafter bakom konsumtion som leder till ökad energianvändning vara relationen mellan samhälleliga förutsättningar ovh individers attityder, beteende o

Introduction: Individuals with severe alpha-1-antitrypsin (AAT) deficiency have a well-known risk of developing emphysema but it is not known at which age the first symptoms occur and lung function declines. The aim of this study was to examine the prevalence of smoking, respiratory symptoms and lung function at the age of 30 in AAT-deficient individuals (PiZ and PiSZ) identified by neonatal scree

A comparative analysis of the electron-hole (e-h) excitation mechanism of impurity luminescence has been performed for wide-gap oxides (WGO) and alkali halides crystals (AHC). A low quantum yield of scintillation in WGO with respect to that in AHC is connected with the high value of the average energy needed for the creation of an e-h pair in WGO. In AHC and many WGO, the width of a valence band E

A coordinated movement is easy to recognize, but we know little about how it is achieved. In search of the neural basis of coordination, we present a model of spinocerebellar interactions in which the structure-functional organizing principle is a division of the cerebellum into discrete microcomplexes. Each microcomplex is the recipient of a specific motor error signal-that is, a signal that conv

Poly(propylene oxide)s with a comblike architecture were prepared by using an ethylene-vinyl alcohol copolymer as a macroinitiator for anionic graft polymerisation of propylene oxide. The densely grafted polymers were subsequently modified by capping the terminal hydroxyl groups with hexadecanoyl chloride to produce aggregating polymers. Dilute solution viscometry showed that the hydroxyl and hexa

An eagerly awaited prostate cancer susceptibility gene has been announced. But does the candidate live up to expectations?

Different adsorption phases of iron phthalocyanine (FePc) on highly oriented pyrolitic graphite (HOPG) have been characterized by scanning tunnelling microscopy (STM). Evaporation of FePc onto the graphite (000 1) surface, kept at room temperature. results in the formation of three-dimensional molecular islands. After annealing to 400 degrees C different two-dimensional features Lire identified. d

Background: In obese patients, jejunoileal bypass (JIB) has been used to induce weight reduction. Changes in the neuroendocrine system may be affected by the JIB-operation, because the proximal small intestinal mucosa has a rich supply of endocrine cells and peptidergic nerves. Materials and Methods: In 37 obese patients operated with JIB 1-30 years ago, small intestinal biopsies were taken at the

There are two fundamental aspects of the notion of a self: (i) it is the owner of one's experiences, that to which one's experiences are properly attributed, and (ii) it perceives itself. (ii) is a condition on the self's being capable of attributing experiences to itself or being introspectively aware of its experiences, which constitutes a third, higher-order aspect of the self. I claim that it

Tailbiting codes encoded by convolutional encoders are studied. An explanation is given for the fact that, at low signal-to-noise ratios, a systematic feedback encoder results in fewer decoding bit errors than a nonsystematic feedforward encoder for the same tailbiting code. The analysis is based on a recently introduced code property, namely, the weight density of distance-d codewords. For a give
