Control of crop pests by shifting host plant availability and natural enemy activity at landscape scales has great potential to enhance the sustainability of agriculture. However, mainstreaming natural pest control requires improved understanding of how its benefits can be realized across a variety of agroecologies. Empirical studies suggest significant but highly variable responses of natural pes
Objective: The primary aim of this study was to examine the association between the different predicted phenotypes of the polymorphic CYP2D6 gene and the prevalence of adverse drug reactions in patients suffering from depressive disorders. The secondary aim was to investigate if comedication with CYP2D6 inhibitors resulted in more adverse drug reactions due to phenoconversion. Methods: Between Jan
Background: The SIOP-Renal Tumor Study Group (RTSG) does not advocate invasive procedures to determine histology before the start of therapy. This may induce misdiagnosis-based treatment initiation, but only for a relatively small percentage of approximately 10% of non-Wilms tumors (non-WTs). MRI could be useful for reducing misdiagnosis, but there is no global consensus on differentiating charact
Objective: Around 30% of people with schizophrenia are refractory to antipsychotic treatment (treatment-resistant schizophrenia). Abnormal structural neuroimaging findings, in particular volume and thickness reductions, are often described in schizophrenia. Novel biomarkers of active brain pathology such as neurofilament light chain protein are now expected to improve current understanding of psyc
Capturing ultrafast phenomena requires imaging techniques capable of resolving events occurring on femtosecond time scales. Traditional high-speed cameras are limited by electronic readout speeds and cannot reach the terahertz (THz) frame rates necessary to observe processes such as laser filamentation, plasma formation, or light-matter interactions in general. To overcome these limitations, this
Businesses play a key role in transforming production and consumption for sustainability,where circular business models (CBMs) offer one solution to reduce waste and rethink resource use.Although CBMs may be able to provide environmental and economic benefits, it is unclear how they canbe implemented effectively and contribute to sustainability goals. To understand how CBMs cancontribute to broade
This thesis theoretically investigates electronic transport in different low dimensional nanostructures. The miniaturization of electronics means that we reach a limit where quantum effects play a role in electronic devices. To understand and improve electronics at this level it is important to understand the transport properties. Excellent control over the nanostructures also makes them a great p
The introduction of Multiple-Input Multiple-Output (MIMO) systems has dramatically transformed wireless communication systems, in particular in the Fifth Generation (5G) New Radio (NR) systems, fundamentally changing how signals are transmitted and received. MIMO technology deploys numerous antennas to transmit and receive multiple data streams simultaneously.

Optimal time spans in homograft procurement are still debatable among tissue banks and needs to be further investigated. Cell viability decreases at longer preparation intervals, but the effect on collagen and elastic fibers has not been investigated to the same extent. These fibers are of importance to the homograft elasticity and strength. The objective of this study was to analyze the mechanica
The oxides that form during thermal oxidation of natural FeS2 (pyrite and marcasite) consist of nanometer-sized crystals of alpha-Fe2O3 and gamma-Fe2O3. This is shown with heating experiments that were made up to 650 degrees C, which resembles temperatures used in metallurgical processes. It is shown that magnetic measurements can play a key role in the investigation of this reaction, due to the u
Popular Abstract in Swedish Ansamlingen av avfall i soptippar skapar miljöproblem då mikrobiell nedbrytning av lättnedbrytbart avfall ger upphov till växthusgaser (metangas och koldioxid). Dessutom bildas förorenade lakvatten på grund av att regnvatten tränger igenom deponin. Lakvattnet innehåller ofta höga halter av ammoniumjoner samt organiska ämnen. Ammoniumjonen är en giftig förening som ger aAbstract The efficiency of different leachate treatment methods for the removal of refractory organic compounds and ammonium-nitrogen was investigated. The methods evaluated were nitrification, denitrification, adsorption onto activated carbon, precipitation by ferric chloride or aluminum sulphate and oxidation by ozone or Fenton´s reagent. Furthermore, analyses were performed on leachates from mu
This paper contains a joint ESHG/ASHG position document with recommendations regarding responsible innovation in prenatal screening with non-invasive prenatal testing (NIPT). By virtue of its greater accuracy and safety with respect to prenatal screening for common autosomal aneuploidies, NIPT has the potential of helping the practice better achieve its aim of facilitating autonomous reproductive
Multiple-quantum spin relaxation is a sensitive probe for correlated conformational exchange dynamics on microsecond to millisecond time scales in biomolecules. We measured differential H-1-N-15 multiple-quantum relaxation rates for the backbone amide groups of the E140Q mutant of the C-terminal domain of calmodulin at three static magnetic field strengths. The differential multiple-quantum relaxa
Low cholesterol levels have been correlated with both suicidal and aggressive behavior in psychiatric patients. Few studies have investigated associations between serum lipid profiles and both aggressive state and trait. Fifty-two psychiatric medication-free inpatients were included in this study after a suicide attempt. Composite scores of “State Aggression” and “Trait Aggression” were calculated
BACKGROUND: /st> Previous studies have indicated that autoantibodies may be detected years before the clinical onset of rheumatoid arthritis (RA). Cartilage biomarkers, such as cartilage oligomeric matrix protein (COMP), have not been studied previously in samples collected before the diagnosis of RA. METHODS: /st> Between 1991 and 1996, 30 447 subjects were included in the Malmö Diet Cancer Study
Over the last decades or so, artificial neural networks (ANNs) have become one of the most promising tools for modelling hydrological processes such as rainfall-runoff processes. In most studies, ANNs have been demonstrated to show superior result compared to the traditional modelling approaches. They are able to map underlying relationships between input and output data without detailed knowledge
We have examined whether in vivo exposure to the glutamate analogue, kainic acid, induces cell loss through apoptosis and/or through necrosis. The vulnerability of rabbit retinal cells was evaluated by routine histopathology. The DNA fragmentation was examined using an in situ method (TUNEL: TdT-mediated biotin-dUTP nick-end labelling) and agarose gel electrophoresis of extracted retinal DNA. Reti
Popular Abstract in Swedish Akut bukspottkörtelinflammation, akut pankreatit (AP), är en sjukdom med varierande kliniska presentationer; från en mild och ödematös, till en svår och nekrotiserande form. Ungefär 75% av patienter med AP utvecklar en mild, självbegränsande sjukdom, men hos resten av patienterna progredierar sjukdomen till en svår form och dödligheten är så hög som 30% i denna grupp avAcute pancreatitis (AP) is an inflammatory disease with variable severity ranging from mild interstitial edematous to severe necrotizing disease. The overall mortality rate of AP is 8-9%. Specific treatment of AP is lacking which is partly related to an incomplete understanding of the basic pathophysiology behind the disease. It is widely held that premature intra-cellular trypsinogen activation a
The overall aim of this thesis was to describe the experiences of obstetricians and parents and the attitudes of midwives in relation to critical situations during pregnancy and birth. The data collection (Paper I and II) started in year 2000 with interviews with obstetricians (n=14) concerning the meaning of being in ethically difficult situations. During 2002 to 2004 interviews with parents (n=2
