Lipid rafts in immune signalling: current progress and future perspective

Lipid rafts are dynamic assemblies of proteins and lipids that harbour many receptors and regulatory molecules and so act as a platform for signal transduction. They float freely within the liquid-disordered bilayer of cellular membranes and can cluster to form larger ordered domains. Alterations in lipid rafts are commonly found to be associated with the pathogenesis of several human diseases and

A sprinkling of gold dust : Pine pollen as a carbon source in Baltic Sea coastal food webs

Allochthonous subsidies to marine ecosystems have mainly focused on biogeochemical cycles, but there has also been recent interest in how terrestrial carbon (C) influences marine food webs. In the Baltic Sea, pine (Pinus sylvestris) pollen is found in large amounts in shallow bays in early summer. Pollen is a significant C-source in freshwater ecosystems and may also be important in coastal food w

Chlorophenol stress affects aromatic amino acid biosynthesis-a genome-wide study

Chlorophenols are a class of chemicals commonly used in preservatives, disinfectants, algaecides, herbicides and pesticides. However, there is a growing evidence that these compounds are a threat to human health. This is alarming as many chlorophenols are common pollutants found in the global environment at potentially biohazardous levels. Despite chlorophenols being abundant, widely used and pois

Seasonal genotype dynamics of a marine dinoflagellate : Pelagic populations are homogeneous and as diverse as benthic seed banks

Genetic diversity is the basis for evolutionary adaptation and selection under changing environmental conditions. Phytoplankton populations are genotypically diverse, can become genetically differentiated within small spatiotemporal scales and many species form resting stages. Resting stage accumulations in sediments (seed banks) are expected to serve as reservoirs for genetic information, but so

A detailed study on the micro-explosion of burning iron particles in hot oxidizing environments

As a promising carbon-free fuel, iron powder can directly combust with air and has great potential to provide clean and high-grad heat for various applications. The combustion characteristics of iron particles are of great significance for developing iron combustion model, designing efficient combustor, and optimizing combustion technologies. In this work, the micro-explosion behavior of burning i

Real-time accelerator diagnostic tools for the max iv storage rings

In this paper, beam diagnostic and monitoring tools developed by the MAX IV Operations Group are discussed. In particular, beam position monitoring and accelerator tunes visualization software tools, as well as tools that directly influence the beam quality and stability, are introduced. An availability and downtime monitoring application is also presented.

Raman spectroscopy for characterizing porous carbon

Raman spectroscopy is performed to disclose structural properties of porous carbon samples including lignocellulosic biomass. Analysis of spectral signatures of carbon, around 1350 cm-1 and 1580 cm-1, indicates higher porosity for the biomass sample.

AI i offentlig sektor : Från etiska riktlinjer till lagstiftning

Användningen av artificiell intelligens (AI), det vill säga en rad primärt databeroende metoder och teknologier för bland annat prediktion och automation, tycks bidra till en omvälvande period i den offentliga förvaltningen. Detta skifte föranleder ett styrningsbehov, ofta kopplat till tillitsfrågor, vilket i en internationell kontext inte minst syns i en stor mängd etiska riktlinjer och principie

AI and Patients’ Rights : Transparency and information flows as situated principles in public health care

The development of artificial intelligence (AI) for medicine and health care is rapidly evolving. However, the automation, scale and data dependency of AI-driven decision-making and decision-support calls for a reassessment of principal ethical and legal norms of transparency, in the light of these novel methodologies. The quality of AI-driven health care, we argue, is depending on it. In this cha

Countercurrent distribution of lymphocytes from human peripheral blood in an aqueous two-phase system. : II. Separation into subsets of lymphocytes with distinctive functions

Lymphocytes from human peripheral blood were separated by Countercurrent distribution (CCD) in a charged aqueous two-phase system composed of Dextran T 500 and polyethylene glycol 6000. Maximal responses to the T-cell mitogens phytohemagglutinin and concanavalin A were detected in a part of the distribution corresponding to the area where the highest percentage of E rosetting cells were seen. Anti

Systematic analysis of mycobacterial acylation reveals first example of acylation-mediated regulation of enzyme activity of a bacterial phosphatase

Protein lysine acetylation is known to regulate multiple aspects of bacterial metabolism. However, its presence in mycobacterial signal transduction and virulence-associated proteins has not been studied. In this study, analysis of mycobacterial proteins from different cellular fractions indicated dynamic and widespread occurrence of lysine acetylation. Mycobacterium tuberculosis proteins regulati

Självskadebeteende : Upptäcka, förstå och behandla

Att möta människor som avsiktligt skadar sig själva är en utmanande situation. Hur förstår man vilken funktion det självskadande beteendet fyller för personen? Hur hanterar man sina egna tankar och känslor?I den här boken ges kunskap och praktisk vägledning för att skapa en konstruktiv och hjälpsam behandling och relation vid självdestruktiva handlingar. Författarna beskriver hur utredning och bed

Refugees’ Integration in the Built Environment: The Sweden Case

The resettlement and integration of a displaced population into a new society faces a plethora of challenges. These range from lack of national legal frameworks to plan and implement planned relocation, to the absence of a long-term vision, inadequate funds, and poor institutional structures. The 3-year EU Erasmus+ funded REGARD Project (REbuildinG AfteR Displacement) set out to address some of th
