Concordance between four European centres of PET reporting criteria designed for use in multicentre trials in Hodgkin lymphoma

To determine if PET reporting criteria for the Response Adapted Treatment in Hodgkin Lymphoma (RATHL) trial could enable satisfactory agreement to be reached between 'core' laboratories operating in different countries. Four centres reported scans from 50 patients with stage II-IV HL, acquired before and after two cycles of Adriamycin/bleomycin/vinblastine/dacarbazine. A five-point scale was used

TERT promoter mutations occur frequently in gliomas and a subset of tumors derived from cells with low rates of self-renewal

Malignant cells, like all actively growing cells, must maintain their telomeres, but genetic mechanisms responsible for telomere maintenance in tumors have only recently been discovered. In particular, mutations of the telomere binding proteins alpha thalassemia/mental retardation syndrome X-linked (ATRX) or death-domain associated protein (DAXX) have been shown to underlie a telomere maintenance

Feedback control of learning by the cerebello-olivary pathway.

The ability to anticipate future events and to modify erroneous anticipatory actions is crucial for the survival of any organism. Both theoretical and empirical lines of evidence implicate the cerebellum in this ability. It is often suggested that the cerebellum acquires "expectations" or "internal models." However, except in a metaphorical sense, the cerebellum, which consists of a set of interco

Neighborhood walkability, deprivation and incidence of type 2 diabetes: A population-based study on 512,061 Swedish adults.

Neighborhood walkability has been associated with increased physical activity, but only a few studies have explored the association between walkability and health outcomes related to physical activity, such as type 2 diabetes. The aim of this study was to investigate the association between objectively assessed neighborhood walkability and the 4-year incidence of type 2 diabetes in a sample of 512

The 125th Anniversary of the Troger's Base Molecule: Synthesis and Applications of Troger's Base Analogues

In 2012 we celebrate the 125th anniversary of the unique molecule Troger's base (TB), first synthesized by Julius Troger in 1887. Being a V-shaped C2-symmetric chiral molecule, it possesses many interesting features. The TB field was reopened in 1985, when Craig S. Wilcox published the first crystallographic study of TB and described the synthesis and potential applications of TB analogues in supr

Panel cointegration tests of the sustainability hypothesis in rich OECD countries

This study reexamines the sustainability hypothesis by testing whether government revenues and expenditures for eight rich OECD countries between 1977Q1 and 2005Q4 are cointegrated. For this purpose, a nonstationary panel data approach is adopted, which is general enough to permit for cross-country dependence as well as structural breaks representing major shifts in fiscal policy. In contrast to m

Playfights as trouble and respite

Playfulness is easily overlooked in studies of total institutions because it does not match what we expect from institutional order. By studying playfulness ethnographically, social life in today’s institutions can be depicted both more naturalistically and more unexpectedly. This article explores how members of Swedish youth care institutions enact and respond to playful disputes or aggression in

De-Essentializing the Knowledge Intensive Firm: Reflections on Sceptical Research Going against the Mainstream

This paper provides an updated summary and discussion of my 1993 JMS paper 'Organization as rhetoric: knowledge-intensive firms and the struggle with rhetoric', and relate this to my own and others' later work in the area explored in the paper: knowledge-intensive work and discourse. A key aspect of knowledge work is the ambiguity of what it stands for, what people working with 'knowledge' are doi

Tea and coffee consumption and risk of esophageal cancer: The European prospective investigation into cancer and nutrition study

Epidemiological data regarding tea and coffee consumption and risk of esophageal cancer (EC) is still inconclusive. We examined the association of tea and coffee consumption with EC risk among 442,143 men and women without cancer at baseline from 9 countries of the European Prospective Investigation into Cancer and Nutrition. Tea and coffee intakes were recorded using country-specific validated di

The Significance of Emulation in the Oral Interaction Between Teacher and Students

The lack of attention to the role of emotions generally has led modern learning theories to neglect the importance of emulation as a pedagogical support to students’ learning. One reason could be that the influence of teacher personality is not considered in relation to learning outcome. Another reason may be that the concept of emulation has been used as a psychological conception for one-way tra

Towards an integrated global framework to assess the impacts of land use and management change on soil carbon : Current capability and future vision

Intergovernmental Panel on Climate Change (IPCC) Tier 1 methodologies commonly underpin project-scale carbon accounting for changes in land use and management and are used in frameworks for Life Cycle Assessment and carbon footprinting of food and energy crops. These methodologies were intended for use at large spatial scales. This can introduce error in predictions at finer spatial scales. There

Effects of Cooling on Ankle Muscle Strength, Electromyography, and Gait Ground Reaction Forces

The effects of cooling on neuromuscular function and performance during gait are not fully examined. The purpose of this study was to investigate the effects of local cooling for 20 min in cold water at 10 C in a climate chamber also at 10 C on maximal isometric force and electromyographic (EMG) activity of the lower leg muscles. Gait ground reaction forces (GRFs) were also assessed. Sixteen healt

Nanofocused x-ray beams applied for mapping strain in core-shell nanowires

The core-shell nanowires have the promise to become the future building blocks of light emitting diodes, solar cells and quantum computers. The high surface to volume ratio allows efficient elastic strain relaxation, making it possible to combine a wider range of materials into the heterostructures as compared to the traditional, planar geometry. As a result, the strain fields appear in both the c

Mosasaur bite marks on a plesiosaur propodial from the Campanian (Late Cretaceous) of southern Sweden

Although plesiosaurs and mosasaurs co-existed for about 35 million years at the end of the Cretaceous, the fossil record documenting interactions between these two groups of marine reptiles is meagre. The discovery of deeply incised scars on a limb bone of an immature polycotylid plesiosaur from the latest early Campanian (in the European two-fold division of the Campanian Stage) of the Kristianst

Voices on Relocation and Aging in Place in Very Old Age--A Complex and Ambivalent Matter.

PURPOSE: This cross-national qualitative study explores how very old people reflect upon relocation and aging in place. DESIGN AND METHODS: Swedish and German data are utilized in this study. About 80 community-living participants, 80-89 years of age, were interviewed with open-ended questions at home by trained interviewers. The interviews were analyzed by using conventional qualitative content a

The importance of thermal boundary transitions on glacial geomorphology; mapping of ribbed/hummocky moraine and streamlined terrain from LiDAR, over Småland, South Sweden

In this paper we synthesise previous sedimentological studies and new, high resolution, digital elevation models from southern Småland to investigate the evolution of a deglacial landscape. Starting approximately at the deglacial highest shoreline, there is a 20-40 km wide zone of ribbed and hummocky moraine that can be connected to the predominantly subaqueous Göteborg moraine. North of this ther

Governing renewable energy in the EU: Confronting a governance dilemma

Promoting renewable energy sources (RES) has been addressed a key strategy for mitigating climate change, the governing in which has turned out a challenging and protracted task for the EU. There is often an implicit assumption that concern for climate change drives energy policy, but a closer look at the development of European RES policy indicates how EU governors have had to confront a range of
