AbstractAlloreactivity is the strongest known primary immune response. Its clinical manifestations are graft rejection, graft-versus-host disease and graft-versus-leukemia effect. The strongest stimulation by allogeneic cells is due to incompatibility at the major histocompatibility complex (MHC) genes. However, the non-MHC genes also participate in allogeneic response. Here we present a mouse model for study of the role of non-MHC genes in regulation of alloreactivity and show that they besides encoding antigens also regulate the responsiveness.

Abstract:
Introduction: It is known that breast cancer is the type of cancer that mostly affects women in the world, both in the developing and developed countries, with about 2.3 million new cases in 2020, comprising 25% of all cancers diagnosed in women. Vitamin D concentration has been studied as a risk and prognostic factor in women with breast cancer; its deficiency is common in women with postmenopausal breast cancer, and some evidence suggests that low vitamin D status increases the risk for disease development. The impact of vitamin D at the time of diagnosis on the outcome of patients with brea

Abstract:
4-quinolones derivatives can present fluorescent properties, depending on their substituents and on the chemical environment (e.g., acidic medium), allowing their application as ion sensors. We theoretically evaluated the photophysical properties of previously synthesized 3-acyl-4-quinolones to verify how different substituents (R1=H, NH2 and R2 = OEt, OH, NHPh) affect their absorption profiles and the emission profile of a reference compound, PB3. All DFT and TD-DFT calculations were performed at B3LYP-D3/6-311++G(d,p) level and continuum polarization model for simulated acetonitrile as solve

Abstract:
The interactions of noncoordinated water or ammonia molecules with aromatic rings, as well as coordinated water or coordinated ammonia molecules with aromatic rings have been investigated by searching the Cambridge Structural Database (CSD) and through quantum-chemical calculations. The data from the CSD show that for noncoordinated systems distances between the interacting fragments are the shortest in case of negative C6-aromatic groups and the longest in case of positive C6-aromatic groups. In the case of contacts between coordinated water or ammonia molecules and C6-aromatic group, opposit

Abstract:
Sulfide (S2−) is a biologically and environmentally important anion. Exposure to the sulfide anion can cause chronic, respiratory diseases and irritations in the skin and mucous membranes. The protonated HS− or H2S forms are more toxic than the S2− itself. A derivative of the family of 2,4,6-triaryl-pyrylium cations bearing an amine in the para position of the 4-aryl group is sensitive for detecting sulfide anions in solution. Through DFT calculations, performed at level B3LYP/6-31+G(d) in gas phase, these authors present the thermodynamic stability of the interaction of chemodosimeters derive

Abstract:
A novel concept for injection of gaseous hydrogen (fuel) into a stream of air (oxidant) with in low-NOx gas turbine combustion systems is proposed and tested experimentally in a laboratory bluff body (BB) burner. Instead of conventional injection nozzles, that represent undesired point sources of the highly reactive fuel, the injection concept presented in this paper employs porous steel components, with anticipation to achieve hydrogen injection into air in a compositionally diluted and spatially distributed fashion. The BB burner is tested with four different bluff bodies: three bluff bodies

Abstract:
Under 1900-talet skedde en snabb tillväxt av antalet företag i Sverige som tillverkade jordbruksmaskiner och -redskap. Det är lätt att konstatera att de allra flesta av dessa försvann från marknaden med tiden. Rolf Larsson nämner i sin bok Från stall till maskinhall att av de 200 svenska maskintillverkare som han tar upp under 1900-talet, överlevde endast ett 40-tal millennieskiftet. Det kan därför vara intressant att försöka ta reda på vad som egentligen hände med alla de företag som var framgångsrika under vissa delar av 1900-talet, men som senare under seklet kom att läggas ned, köpas upp a

Abstract:
Skötseln av våra städer blir alltmer central allteftersom städerna växer och klimatet förändras. Existerande, samt planerade, grönytor, parker och trädplanteringar bör därför förvaltas och skötas på ett lämpligt och hållbart vis. Träd utgör en viktig del av utemiljön och i detta projekt fokuseras på om det går att samla all information om träd i en smart applikation för att öka trädens nytta genom bättre skötsel. Långsiktigt finns ambitionen att skapa en applikation för behovsstyrd skötsel av hela utemiljön, men i detta projekt görs en avgränsning till träd. Arbetet har genomförts i tre steg:

Abstract:
Intresset för havsbaserad vindkraft har ökat markant med samhällets ökade behov av elektrifiering och förnybar energi. Samtidigt kan etablering av vindkraft påverka det marina ekosystemet där fisk har en central roll. Idag har flera fiskarter dålig status på grund av mänsklig påverkan och det kan uppstå frågetecken kring vilka konsekvenser en storskalig utbyggnad kan ha. Kunskapsläget om hur fisk kan påverkas av havsbaserad vindkraft är fortfarande inte tillräcklig utvecklat för att dra generella slutsatser - hur fiskar kan påverkas av vindparkerna förväntas variera både geografiskt och på en

Abstract:
Det pågår en omställning av jord- och trädgårdsbruket, både med hänsyn till hållbar produktion och pågående klimatförändringar. Som en del av EUs arbete att utveckla lantbruket mot en mer hållbar produktion har kommissionen lagt fram ett förslag på minskning av växtskyddsmedel om minst 50 %, totalt sett inom EU, senast 2030. För Sveriges del innebär förslaget, enligt preliminära beräkningar, att vi behöver minska mängden växtskyddsmedel med 35-36 %. För att ersätta funktionen av denna mängd växtskyddsmedel behövs ett integrerat tillvägagångssätt som kräver tillgång till andra effektiva metoder
