Search for dark matter at colliders

Among the numerous proposals to explain the nature of dark matter, there is the weakly interacting massive particle (WIMP) scenario, which is based on a simple assumption that dark matter was in thermal equilibrium in the early hot Universe, and its particles have mass and interactions not too different from the massive particles in the standard model. In this Progress Article we overview the infe

Sequential Proton-Coupled Electron Transfer Mediates Excited-State Deactivation of a Eumelanin Building Block

Skin photoprotection is commonly believed to rely on the photochemistry of 5,6-dihydroxyindole (DHI)- and 5,6-dihydroxyindole-2-carboxylic acid (DHICA)-based eumelanin building blocks. Attempts to elucidate the underlying excited-state relaxation mechanisms have been partly unsuccessful due to the marked instability to oxidation. We report a study of the excited-state deactivation of DHI using ste

Ultrafast Time-Resolved X-ray Absorption Spectroscopy of Ferrioxalate Photolysis with a Laser Plasma X-ray Source and Microcalorimeter Array

The detailed pathways of photoactivity on ultrafast time scales are a topic of contemporary interest. Using a tabletop apparatus based on a laser plasma X-ray source and an array of cryogenic microcalorimeter X-ray detectors, we measured a transient X-ray absorption spectrum during the ferrioxalate photoreduction reaction. With these high-efficiency detectors, we observe the Fe K edge move to lowe

Targeted Proteomics Approach for Precision Plant Breeding

Selected reaction monitoring (SRM) is a targeted mass spectrometry technique that enables precise quantitation of hundreds of peptides in a single run. This technique provides new opportunities for multiplexed protein biomarker measurements. For precision plant breeding, DNA-based markers have been used extensively, but the potential of protein biomarkers has not been exploited. In this work, we d

Irreversible Kidney Damage due to Multicentric Castleman's Disease

Castleman's Disease (CD) is a rare lymphoproliferative disorder accompanied by marked systemic inflammatory response. Morphological diagnosis of CD requires biopsy of the whole of the involved lymph node tissue. Three histologic variants have already been described in CD morphology (hyaline vascular, plasma-cell, and mixed). In this study, we report a case of a multicentric Castleman's disease of

Male Experiences of Life After Recovery From an Eating Disorder

Supply Chain Risk Management : En modell för riskbedömning och riskhantering

Dagens moderna samhälle är ett i många avseenden sårbart samhälle. Det har inte varit någon medveten strävan utan är en konsekvens av att samhället till stor del kommit att bli uppbyggt kring försörjningskedjor (supply chains). I dessa hårt integrerade kedjor med ett flertal ofta globalt utspridda led flyter en ständig ström av fysiska varor, tjänster samt kombinationer av varor och tjänster.Det e

Medication packaging and older patients: a systematic review

The global challenges posed by demographic change call for more senior-friendly medication packaging. This paper presents a comprehensive integrated view and synthesis of the literature on medication packaging and older people. Considering the multidisciplinary nature of the research field, a systematic review was conducted in four databases (Scopus, Web of Science, Medline and Engineering Village

Pharmaceutical packaging for older patients - A design and innovation perspective

Pharmaceutical packaging is linked to important demographic changes. Aging ofpopulations is one of the demographic changes which has called for more attention, especially in well-developed countries. The increase in life expectancy represents a positive consequence of years of research, development of medications, and improvement in life habits. In spite of that, the growth in the number of people

Long-term adjustment to living with an ileal pouch-anal anastomosis

PURPOSE: The aim of this study was to describe long-term adjustment to life with an ileal pouch-anal anastomosis after surgery for ulcerative colitis, to investigate the relationship of pouch function to adjustment, and to explore factors affecting quality of life.METHODS: A total of 369 patients treated between 1982 and 1993 were included in the study. Questionnaires designed to assess bowel (pou

Concerns and quality of life before surgery and during the recovery period in patients with rectal cancer and an ostomy

PURPOSE: Rectal cancer is the most common reason for a person to undergo ostomy surgery. The aim of this study was to assess concerns and health-related quality of life (HRQOL) before surgery and during the first 6 months following ostomy surgery in the presence of rectal cancer.SUBJECTS AND SETTINGS: The sample comprised 57 patients at a university hospital in Gothenburg, Sweden. Their median age

Ambulanssjukvården måste bli jämlik

Skiftande vårdkvalité hotar patientsäkerheten inom ambulanssjukvården. Nu måste regeringen och Socialstyrelsen skapa nationella riktlinjer, skriver Nätverket för utbildning av ambulanssjuksköterskor .

Positive and negative aspects of colostomy irrigation : a patient and WOC nurse perspective

PURPOSE: Colostomy irrigation (CI) is an effective method to achieve fecal continence in selected persons with a colostomy. The primary aims of the study were to find out to what extent the WOC nurses used CI in their practice and what kind of information the WOC nurses gave patients if they provided explanations and potential solutions when irrigation was not successful in preserving continence.
