Popular AbstractDetta är en histora över teorier om ojämnt utbyte och deras upphovsmän. Den börjar med merkantilismen och Richard Cantillons jordvärdeteori, ger en kort beskrivning av tidig klassisk ekonomi och Gerald Fitzhugh. Bland det tidiga 1900-talets marxistiska ekonomer spelade ojämnt utbyte en roll i Otto Bauers tolkning av nationalistiska motsättningar, och i Henryk Grossmanns verk som enThis is a history of theories and theorists of unequal exchange. Starting with mercantilists and Richard Cantillon's theory based on land values, it briefly covers the early Classical economists and Gerald Fitzhugh. Among early 20th century Marxist economists, unequal exchange appeared in Otto Bauer's explanation of nationalist antagonism, and in Henryk Grossmann as countering the breakdown of cap

More than 500 colorectal tumors with clonal chromosomal abnormalities have been reported. Although the pattern of aberrations is nonrandom, no specific primary or secondary karyotypic abnormality has been identified. Also, the chronological order in which the aberrations appear during disease progression is not well known. One reason why our understanding of the cytogenetic evolution is unclear is

On the basis of text-internal evidence, the article supports the view that the soteriological doctrines of the Bhagavadgītā comprise a structured and progressive system in which partially conflicting elements derived from contemporary religious teachings have been deliberately arranged in hierarchical form, and touches on philological problems in connection with particular passages.

Background: Protein kinase C (PKC) is known to be involved in the pathophysiology of experimental cerebral ischemia. We have previously shown that after transient middle cerebral artery occlusion, there is an upregulation of endothelin receptors in the ipsilateral middle cerebral artery. The present study aimed to examine the effect of the PKC inhibitor Ro-32-0432 on endothelin receptor upregulati

Graft copolymers consisting of polyamide 12 or poly(ethylene-co-vinyl alcohol) as backbone polymers and side chains of poly(ethylene oxide) have been synthesized. The amide and hydroxyl groups of the backbone polymers were used as initiation sites for the polymerization of ethylene oxide (EO). Potassium tert-butoxide was used for ionization of the active groups, and the polymerization of EO was ca

Background-Considerable variability exists in the use of pharmacological thromboprophylaxis among acutely ill medical patients, partly because clinically relevant end points have not been fully assessed in this population. We undertook an international, multicenter, randomized, double-blind, placebo-controlled trial using clinically important outcomes to assess the efficacy and safety of daltepari

1 The endocannabinoid anandamide is an emerging potential signalling molecule in the cardiovascular system. Anandamide causes vasodilatation, bradycardia and hypotension in animals and has been implicated in the pathophysiology of endotoxic, haemorrhagic and cardiogenic shock, but its vascular effects have not been studied in man. 2 Human forearm blood flow and skin microcirculatory flow were reco

This study highlights school nurses' view of schoolchildren's health and their attitude to document it in the school health records. A strategic sample of 12 school nurses was interviewed. The interviews were semistructured and analysed with qualitative content analysis. The findings showed that the school nurses' viewed schoolchildren as physical healthy although they called attention to growing

We report the application of mid-infrared polarization spectroscopy (IRPS) for detection of nascent CO2 and H2O in atmospheric pressure flames. The recorded IRPS spectra demonstrated both the quantitative nature of the method and the suppression of strong infrared emission from flames. In spite of the high line-density of the hot polyatomic ro-vibrational spectrum, lines belonging to different CO2

Popular Abstract in Swedish I hjärnan finns många olika typer av nervceller. De använder sig av olika signalsubstanser, kallade neurotransmittorer, för att kommunicera med andra nervceller. En viss typ av nervceller använder neurotransmittorn dopamin. Dopaminceller finns på många ställen i hjärnan men de flesta ligger i mellanhjärnan i ett par olika cellgrupper som var och en skickar signaler tillParkinsons disease (PD) is a neurodegenerative disorder where dopaminergic neurons of the substantia nigra (SNc) in the mesencephalon are progressively eliminated. The ensuing loss of dopaminergic innervation of the basal ganglia manifests itself as severe motor deficits in PD patients. Clinical trials have shown that cell replacement therapy, where dopaminergic neuroblasts derived from fetal vent
