Photoreceptor evolution: ancient 'cones' turn out to be rods.

Vertebrate rod photoreceptors are thought to have evolved from cone photoreceptors only after the divergence of the jawed and jawless fishes, but this idea is questioned by new evidence that the short 'cones' of jawless sea lampreys are physiologically equivalent to rods.

Queries of MALDI-Imaging Global Datasets Identifying Ion Mass Signatures Associated with Tissue Compartments

Scanning mass spectrometry by matrix assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) creates large volumetric global datasets that describe the location and identity of ions registered at each sampling location. While thousands of ion peaks are recorded in a typical whole tissue analysis, only a fraction of these measured molecules are purposefully scrutinized within a g

Impact of a National system for waitlist prioritization: the experience with NIKE and cataract surgery in Sweden.

Purpose: To evaluate waiting times for first-eye cataract surgery in Sweden following widespread adoption of the Nationell Indikationsmodell for Kataraktextraktion (NIKE) tool for prioritizing patients for cataract surgery. Methods: Waiting times for all first-eye cataract surgeries in Sweden in 2009-2011 were identified from the Swedish National Cataract Register. Waiting times were compared acco

Perfectionism and sense of coherence among patients with eating disorders.

Background: There is a substantial body of research on eating disorders and perfectionism. Also there are several studies on eating disorders and sense of coherence (SOC), but studies regarding all three subjects are sparse. Perfectionism and the degree of SOC are considered central and aggravating aspects of psychiatric conditions, not least in relation to eating disorders. Aims: The present stud

Improving methane production from wheat straw by digestate liquor recirculation in continuous stirred tank processes

Wheat straw is an abundant, cheap substrate that can be used for methane production. However, the nutrient content in straw is inadequate for methane fermentation. In this study, recycling digestate liquor was implemented in single-stage continuous stirred tank processes for enrichment of the nutrient content of straw with the aim of improving the methane production. The VS-based organic loading r

Tourism Place-making: Governance of Locality in Sweden

The presented argument comes from a frustration with the instrumental and de-contextualized view of tourism as a force of spatial change. Consequently, this article empirically illustrates the place-making agency of tourism by engaging with the mundane practicalities of producing geographical attractiveness. Place-making is investigated through four examples of destination developments with differ

Darriwilian (Middle Ordovician) delta C-13(carb) chemostratigraphy in the Precordillera of Argentina: Documentation of the middle Darriwilian Isotope Carbon Excursion (MDICE) and its use for intercontinental correlation

Although documented from Estonia, Latvia, Sweden, eastern North America, and China, the Middle Ordovician (Darriwilian) positive delta C-13 excursion known as the MDICE has previously not been recognized with certainty in South America. The most promising region in South America for detailed Middle Ordovician carbon isotope research is the Precordillera of western Argentina, where there are many e

The International Proteomics Tutorial Programme - reaching out to the next generation proteome scientists

One of the most critical functions of the various Proteomics organizations is the training of young scientists and the dissemination of information to the general scientific community. The education committees of the Human Proteome Organisation (HUPO) and the European Proteomics Association (EuPA) together with the other local proteomics associations are therefore launching a joint Tutorial Progra

Results from a randomized trial of salvage chemotherapy followed by lestaurtinib for patients with FLT3 mutant AML in first relapse

In a randomized trial of therapy for FMS-like tyrosine kinase-3 (FLT3) mutant acute myeloid leukemia in first relapse, 224 patients received chemotherapy alone or followed by 80 mg of the FLT3 inhibitor lestaurtinib twice daily. Endpoints included complete remission or complete remission with incomplete platelet recovery (CR/CRp), overall survival, safety, and tolerability. Correlative studies inc

Reducing lower leg amputations in diabetes: a challenge for patients, healthcare providers and the healthcare system

Amputation of the lower limb is one of the most feared diabetic complications. It is associated with loss of mobility and a poor quality of life. Amputations result in high economic burden for the healthcare system. The financial cost is also high for patients and their families, particularly in countries that lack a comprehensive health service and/or have a low income. Losing a leg frequently im

Albitization and quartz dissolution in Paleoproterozoic metagranite, central Sweden - Implications for the disposal of spent nuclear fuel in a deep geological repository

Hydrothermal alteration resulting in albitization and quartz dissolution has been identified in Paleoproterozoic metagranites down to - 1000 m elevation at Forsmark, Sweden. The alteration features were discovered during investigations to locate a site for the disposal of spent nuclear fuel in a deep geological repository. In general, albitization occurs extensively, but it is also observed locall

Comparison between capillary, venous and arterial levels of protein S100B in patients with severe brain pathology

Background: Protein S100B is soon in clinical use as a sensitive marker after mild traumatic head injury in adults. Initial studies of S100B in pediatric head injury have shown promising results. Venous sampling can be challenging in children and capillary samples are often a preferred option. The aim of the study was to investigate the relation between capillary, venous and arterial measurements

Metabolic factors and blood cancers among 578,000 adults in the metabolic syndrome and cancer project (Me-Can)

We investigated associations between metabolic factors and blood cancer subtypes. Data on body mass index (BMI), blood pressure, blood glucose, total cholesterol, and triglycerides from seven prospective cohorts were pooled (n = 578,700; mean age = 44 years). Relative risks of blood cancers were calculated from Cox regression models. During mean follow-up of 12 years, 2,751 incident and 1,070 fata

Costs of care for people with dementia just before and after nursing home placement: primary data from eight European countries

Dementia is the most common cause of functional decline among elderly people and is associated with high costs of national healthcare in European countries. With increasing functional and cognitive decline, it is likely that many people suffering from dementia will receive institutional care in their lifetime. To delay entry to institutional care, many European countries invest in home and communi

Further Insights into the Catalytical Properties of Deglycosylated Pyranose Dehydrogenase from Agaricus meleagris Recombinantly Expressed in Pichia pastoris

The present study focuses on fragmented deglycosylated pyranose dehydrogenase (fdgPDH) from Agaricus meleagris recombinantly expressed in Pichia pastoris. Fragmented deglycosylated PDH is formed from the deglycosylated enzyme (dgPDH) when it spontaneously loses a C-terminal fragment when stored in a buffer solution at 4 degrees C. The remaining larger fragment has a molecular weight of similar to

Inclusive gauge boson production in the color dipole formalism

The inclusive production of the gauge bosons W-+/- and Z(0) is studied within the color dipole formalism. Gluon saturation effects associated with nonlinear corrections to the QCD dynamics, which are expected to contribute at high energies, are naturally included in such formalism. We estimate the contribution of these effects at LHC energies and compare our results with the next-to-next-to-leadin
