Den amerikanska staden Phoenix ligger omgiven av berg i Sun Valley, Arizona. Klimatet är varmt och glest utspridda kaktusar står som eldgafflar mot skyn. Tänk på en typisk Vilda Västern-film så får du en förnimmelse av vad som kännetecknar Phoenix omgivningar. Trots ökenlika förhållanden bor där idag 1,3 miljoner invånare. Befolkningstillväxten tog fart på allvar luftkonditioneringen introducerade

Transplantation of progenitor cells to the CNS has shown promise in neuronal and glial replacement and as a means of rescuing host neurons from apoptosis. Here we examined the effect of progenitor grafts on neurite extension in the degenerating retina of rd1 ( retinal degeneration 1) mice. Transplantation of retinal progenitor cells induced increased matrix metalloproteinase-2( MMP2) secretion, pa

Family caregivers in cancer and palliative care often face heavy responsibilities and feel insufficiently prepared for the situation as caregivers. This study evaluates short-term and long-term effects of a psycho-educational group intervention aiming to increase preparedness for family caregiving in specialized palliative home care.

Atmospheric dispersion represents a relatively overlooked problem in connection with the ultimate quality of ELT images corrected by adaptive optics (AO). The aim of this paper is to evaluate the contribution from atmospheric dispersion to the background level of the point-spread function (PSF). Since proper suppression of this level is important for the prospects for direct exo-planet observation

Frågor kring tillit i det digitala, tycks det, ställs oftare och oftare: Hur ska vi hantera integritets- och övervakningsfrågor? Hur ska vi hantera den mätbarhet som följer av vår digitaliserade tillvaro? Vad är det som avgör vilka tjänster vi litar på och vilka vi inte litar på, i vilken mån spelar den tekniska säkerheten en roll? Liknande frågor kan ställas om vilka kunskapsinstitutioner vi lita

PURPOSE: The first interim analysis of the phase III, randomized, placebo-controlled TITAN study showed that apalutamide significantly improved overall survival (OS) and radiographic progression-free survival in patients with metastatic castration-sensitive prostate cancer (mCSPC) receiving ongoing androgen deprivation therapy (ADT). Herein, we report final efficacy and safety results after unblin

Bloggpost på nutritionsfakta.se.EAT-Lancetkommissionen lanserade 2019 sin ”the great food transformation”, en modell för hälsosamma matvanor för en växande global befolkning som skulle hålla livsmedelssystemet inom planetens gränser.En uppföljande svensk studie har tagit fram ett eget index för att mäta följsamheten till EAT-Lancetkosten, med en poängsättning som gör det möjligt att se hur väl en

National park agencies in Africa often lack incentives to maximize revenue, despite the decline in conservation subsidies from the State. We explore the potential of pricing policy to generate funds for extensive conservation. We estimate recreation demand by international tourists for a popular South African park, calculate the consumer surplus and find the revenue-maximizing entrance fee. Our re

Lighting control systems have been traditionally employed to reduce energy use for lighting by, for example, maximizing daylight harvesting. When highly efficient light sources are installed and for tasks where maintaining target illuminance is particularly important, designers may decide to prioritize the latter together with energy use. In this context, the use of data-driven algorithms is emerg

Omräkning av barns (≥2 år) kreatininvärden till motsvarande värden vid 18 års ålder och applicerade i Lund–Malmö-formeln för vuxna ledde till avsevärt förbättrad skattning av GFR bland barn vid uppmätt GFR <75, bibehållen noggrannhet ≥75 ml/min/1,73m2 och likvärdig med pediatriska formler.Lund–Malmö-formeln kan användas under hela livet ≥2 år utan plötsliga artificiella förändringar i skattad GFR Age-adjustment of creatinine, i.e. recalculation of childhood levels of creatinine to corresponding levels at 18 years of age and applied in the adult revised Lund-Malmö GFR equation led to markedly improved accuracy in Swedish children (n=1 718) at measured GFR <75 mL/min/1.73 m2 (n=318) and preserved high accuracy at ≥75 mL/min/1.73 m2 (n=1 400). The adjusted LMR equation performed as well as de

PURPOSE: To prospectively examine the association between clonal hematopoiesis (CH) and subsequent risk of lung cancer. METHODS: Among 200,629 UK Biobank (UKBB) participants with whole-exome sequencing, CH was identified in a nested case-control study of 832 incident lung cancer cases and 3,951 controls (2006-2019) matched on age and year at blood draw, sex, race, and smoking status. A similar nes

A comparative experimental investigation has been performed, comparing the emissions from a synthetic jet fuel and from Jet AI. In the investigation, the unburned hydrocarbons were analyzed chemically and the regulated emissions of NOX, CO and HC were measured. All combustion tests were performed under elevated pressures in a gas turbine combustor rig. A Swedish company, Oroboros AB, has developed

Deterministic lateral displacement (DLD) is a powerful bimodal separation scheme [1] based on fluid flow through regular obstacle arrays that in its basic embodiment sends suspended particles in two different directions as a function of size. We show that without the need to seal devices and without the need for fluidic connections or pumps, particle separation can be achieved by the passive flow

Although capacity development has been a key aspect of global aid policy for decades, success is limited. Capacity development is defined as a process, based on a partnership, to develop capacity to achieve a goal. The purpose of this thesis is to increase our understanding of why capacity development does not work as intended, and to inform the discussion on addressing the challenges. Two researc

CONTEXT: As part of a broader institutional initiative, the serious illness care program was implemented in a multi-site academic primary care practice. After 2 years, a minority was observed to be documenting serious illness conversations routinely.OBJECTIVES: We aimed to learn about the motivations and actions of clinicians who routinely conducted and documented serious illness conversations.MET
