Temperature adaptation of bacterial growth and C-14-glucose mineralisation in a laboratory study

Microbial decomposition of soil organic matter (SOM) is the source of most of the terrestrial carbon dioxide emission. Consequently, our ability to predict how climate warming will affect the global carbon (C) budget relies on our understanding of the temperature relationship and adaptability of microbial processes. We exposed soil microcosms to temperatures between 0 and 54 degrees C for 2 months

A comprehensive 1000 Genomes-based genome-wide association meta-analysis of coronary artery disease

Existing knowledge of genetic variants affecting risk of coronary artery disease (CAD) is largely based on genome-wide association study (GWAS) analysis of common SNPs. Leveraging phased haplotypes from the 1000 Genomes Project, we report a GWAS meta-analysis of similar to 185,000 CAD cases and controls, interrogating 6.7 million common (minor allele frequency (MAF) > 0.05) and 2.7 million low-fre

Signs, Senses and Cognition: Lady Welby and Contemporary Semiotics

Susan Petrilli discusses Victoria Welby (1837–1912) and the Signific movement in her book Signifying and Understanding. The disposition of the book is chronological and thematic, and Petrilli’s discussion connects Welby’s work with contemporary semiotics, as well as with the intellectual and scientific landscape of Welby’s own time. For instance, a selection of Welby’s vast correspondence with int

Enhancing Pollen Competition By Delaying Stigma Receptivity: Pollen Deposition Schedules Affect Siring Ability, Paternal Diversity, And Seed Production In Collinsia Heterophylla (Plantaginaceae)

Premise of the study: Even though pollen deposition schedules may have profound effects on the evolutionary outcome of pollen competition, few studies have investigated such effects in relation to pistil traits such as delayed stigma receptivity that enhance pollen competition. In Collinsia heterophylla, a largely outcrossing species with delayed stigma receptivity, we performed a series of contro

Risk of subsequent ischemic and hemorrhagic stroke in patients hospitalized for immune-mediated diseases: a nationwide follow-up study from Sweden

Background: Certain immune-mediated diseases (IMDs) have been associated with increased risk for cardiovascular disorders. The aim of the present study was to examine whether there is an association between 32 different IMDs and first hospitalization for ischemic or hemorrhagic stroke. Methods: All individuals in Sweden hospitalized with a main diagnosis of IMD (without previous or coexisting stro

What Do Prostate Cancer Patients Die Of?

Background. A recent rise in the incidence of prostate cancer and a more favorable outcome have increased the proportions of other causes of death in affected men. Extending the survival of prostate cancer patients thus requires knowledge of all causes of death. Methods. Data on the population, cancers, and causes of death were gathered from the nationwide Swedish Family-Cancer Database. A Cox reg

Assemblies of Pervasive Services

Pervasive computing is a vision about computers blending into the background, being there to assist us when we need them, but not requiring constant attention. The vision covers scenarios in the home, at work, and out in the street, and builds on the ongoing development towards an increasing number of embedded computers with network connectivity. The thesis presents the assembly as a lightweight

Bedside diagnosis of mitochondrial dysfunction in aneurysmal subarachnoid hemorrhage

Objectives - Aneurysmal subarachnoid hemorrhage (SAH) is frequently associated with delayed neurological deterioration (DND). Several studies have shown that DND is not always related to vasospasm and ischemia. Experimental and clinical studies have recently documented that it is possible to diagnose and separate cerebral ischemia and mitochondrial dysfunction bedside. The study explores whether c

Common Missense Variant in the Glucokinase Regulatory Protein Gene Is Associated With Increased Plasma Triglyceride and C-Reactive Protein but Lower Fasting Glucose Concentrations

OBJECTIVE-Using the genome-wide association approach, we recently identified the glucokinase regulatory protein gene (GCKR, rs780094) region as a novel quantitative trait locus for plasma triglyceride concentration in Europeans. Here, we sought to study the association of GCKR variants with metabolic phenotypes, including measures of glucose homeostasis, to evaluate the GCYR locus in samples of no

Cartilage destruction - Release of type IX collagen in joint disease

Cartilage is of vital importance for the function of joints. It is characterized by a prominent extracellular matrix (ECM) that is produced and maintained by relatively few cells of one type, the chondrocyte. The cartilage ECM consists of collagen fibrillar networks, proteoglycan aggregates, and a number of other molecules united in numerous interactions. This work focused at identifying catabolic

Alternative analyses for handling incomplete follow-up in the intention-to-treat analysis: the randomized controlled trial of balloon kyphoplasty versus non-surgical care for vertebral compression fracture (FREE)

Background: Clinical trial participants may be temporarily absent or withdraw from trials, leading to missing data. In intention-to-treat (ITT) analyses, several approaches are used for handling the missing information - complete case (CC) analysis, mixed-effects model (MM) analysis, last observation carried forward (LOCF) and multiple imputation (MI). This report discusses the consequences of app

Propane Dehydrogenation Catalyzed by ZSM-5 Zeolites. A Mechanistic Study Based on the Selective Energy Transfer (SET) Theory.

Experimentally determined activation energies of propane dehydrogenation catalyzed by ZSM-5 zeolites have been used to test the SET theory. The basis of this theory is that the catalyst system transfers vibrational energy via a resonance process to a specific vibration mode of the reacting molecule. Being excited up to a certain number of vibrational quanta the molecule is brought to reaction. By

How does a diurnal hawkmoth find nectar? Differences in sensory control with a nocturnal relative

Recent research shows that a nocturnal hawkmoth, Manduca sexta, inspects flowers in search for nectar by means of a series of hovering and proboscis movements controlled by different sensory modalities, mainly vision and mechanoreception. The diurnal Macroglossum stellatarum is a closely related hawkmoth challenged with the same task but under illuminances 6-8 orders of magnitude higher. Here, we

SHUT UP 'N' PLAY! Negotiating the Musical Work

'SHUT UP ’N’ PLAY! Negotiating the Musical Work’ is a piece of artistic research that attempts to merge artistic practice, qualitative research methods and critical analysis in a project concerned with contemporary performance practices, and specifically how these practices are created and transmitted in the interaction between composer and performer. By way of a critical reading of the musico-phi
