Increasing demands for highly sensitive, accurate, fast and portable analytical assays have led to the development of new analytical tools. The integration of highly specific biological sensing elements and appropriate transducers has enabled design of even more efficient biosensor devices for the detection of target substances. In a clinical setting, early detection of biomarkers is crucial for
Mörk materia har funnits sedan tidernas begynnelse, från den Stora Smällen. Under Universums första hundratals miljoner år var tyngdkraften från den mörka materian så kraftfull att den drog till sig den vanliga materian, som muskler till revben, och formade gigantiska strukturer. De första galaxerna växte där dessa strängar möttes.Galaxer kolliderade med andra galaxer, och slogs samman för att
Security for outsourced control applications can be provided if the physical plant is enabled with a mechanism to verify the control signal received from the cloud. Recent developments in modern cryptography claim the applicability of verifiable computation techniques. Such techniques allow a client to check the correctness of a remote execution. This article delivers a proof of concept for applic
This paper reconsiders how central banks get involved in the process of determining nominal variables such as market interest rates and inflation rates. It is argued that the traditional story deriving central bank power from its monopoly of issuing base money is flawed. That story - in its various guises - is based on the quantity equation. This equation, however, is only applicable in the hypoth
Anhedoni, minskad motivation att uppleva lust, är associerad med förändringar i belöningssystemet. Belägen i ventrala striatum utgör den bilaterala nucleus accumbens (NAcc) den centrala noden i detta nätverk, där dopamin agerar som huvudsaklig excitatorisk neurotransmitter. Studier med funktionell magnetresonanstomografi (fMRI) har visat att aktiviteten i ventrala striatum minskar under belöningsbAnhedonia, reduced motivation to experience pleasure, is associated with alterations in the circuitry of the reward system. Located in the ventral striatum, the bilateral nucleus accumbens (NAcc) is the central hub of this network where dopamine acts as the main excitatory neurotransmitter. Studies using functional magnetic resonance imaging (fMRI) found that activity in the ventral striatum is de
The tendency to buy expensive and unnecessary goods is a pattern of consumer behavior that is becoming all too common in our society. We consume luxury items to satisfy practical needs that are already satisfied in the quest toward self-fulfillment, or simply to impress those around us. The phenomenon of “status consumption” has become increasingly evident in modern society. Although conspicuous c
Martin Johansson är forskargruppsledare för den här forskargruppenWe mainly study two important aspects of human kidney disease. First, we study the cellular background for kidney regeneration. The traditional concept that the human kidney lacks a stem cell compartment has recently been challenged by an alternative view, stating that stem cells indeed are localized to the kidney. The issue is thus far from settled and we are currently researching this important
Transfusion-related acute lung injury (TRALI) remains a leading cause of transfusionrelated deaths. In most cases, anti-leukocyte antibodies in the transfusion product trigger TRALI, but not all anti-leukocyte antibodies cause TRALI. It has been shown that the anti-major histocompatibility complex (MHC) class I antibody 34-1-2S (anti-H-2Kd) causes TRALI in BALB/c mice (MHC class I haplotype H-2Kd)
