Konsumtion i kristider - effekter av stigande livsmedelspriser

Under 2022 och 2023 ökade livsmedelspriserna kraftigt. Även energipriserna steg kraftigt under 2022. För att motverka den stigande inflationen höjde Riksbanken styrräntan. Sammantaget medförde det betydande kostnadsökningar för de svenska hushållen. I detta projekt har vi studerat hur prisökningarna har påverkat livsmedelsförsäljningen inom detaljhandeln och kostintaget på befolkningsnivå. Analyse

Myeloperoxidase expressing tumor associated neutrophils are associated with worse prognosis in metastatic breast cancer patients

Tumor associated neutrophils (TANs) exert dual and opposing functions in tumors, acting pro-tumorigenic and anti-tumorigenic, depending on tumor progression, polarization state and subtype. Consequently, the prognostic impact of TANs in breast cancer is also contradictory. Since neutrophils are critically needed to fight infections in cancer patients, the mediators leading to tumor progression nee

Oxy-ethane combustion : Measurements of the laminar burning velocities and kinetic insights into CO2 effects

Oxy-fuel combustion is regarded as an underpinning technology for carbon capture and utilization. Ethane (C2H6) is the primary non-methane component in natural gas and a fundamental C2 fuel. In this work, laminar burning velocities (LBV) of C2H6/O2/CO2 mixtures were measured using the heat flux method at atmospheric pressure, spanning initial temperatures of 308–348 K, equivalence ratios of 0.6–1.

Stairway to heaven via the highway to hell : a qualitative study on patients’ experience of knee joint replacement surgery

Background: Knee replacement (KR) is the most common osteoarthritis (OA) related surgery. Studies suggest that there are major international and national disparities in pre-operative information, support and access to rehabilitation which have a substantial impact on patients’ perceived outcomes of the KR. The aim of this qualitative study was to explore experiences and perceptions of the care pat

High tumor expression of CTLA4 identifies lymph node-negative basal-like breast cancer patients with excellent prognosis

Background: Tumor immune cell infiltration is a favorable prognostic factor in triple-negative breast cancer. Most triple-negative tumors belong to the aggressive basal-like subtype. We hypothesized that immune gene expression may identify low-risk patients for whom adjuvant chemotherapy can be de-escalated. Methods: The expression of 753 immune-related genes was analyzed in tumor biopsies from 45

The disease course in microscopic colitis may be influenced by hormonal factors

Background: Microscopic colitis (MC) is characterized by non-bloody, watery diarrhea predominantly in elderly women. Known risk factors are smoking, medication with NSAIDs, PPIs or SSRIs, while data on hormonal factors is sparse. The aim of the present study was to investigate whether hormonal factors that disrupt the sex hormonal balance could have an impact on the disease course in MC. Methods:

Neural networks with personalized training for improved MOLLI T1 mapping

Background: The aim of this study was to develop a method for personalized training of Deep Neural Networks by means of an MRI simulator to improve MOLLI native T1 estimates relative to conventional fitting methods. Methods: The proposed Personalized Training Neural Network (PTNN) for T1 mapping was based on a neural network which was trained with simulated MOLLI signals generated for each individ

No effect of novel exploration on the consolidation of extinction learning in human context conditioning

Animal research show that a novel exploration task performed shortly before a learning episode can strengthen hippocampal memory consolidation through behavioural tagging mechanisms. The aim of the present study was to conceptually translate behavioural tagging results to humans using a novel exploration task in virtual reality. Mimicking conditions for animal research, sixty participants underwen

Doublet decoding of tRNASer3 demonstrates plasticity of ribosomal decoding center

Frameshifts can be caused by specific combinations of tRNA and mRNA. The wildtype AGC-decoding E. coli tRNASer3GCU has been shown to induce −1 ribosomal frameshifting on GCA alanine codons, and proposed to read a two-base codon instead of a canonical triplet. However, it has remained unclear whether this type of non-cognate decoding can be accommodated by the ribosome. Here, we perform single-part

Sedation and analgesia in post-cardiac arrest care : a post hoc analysis of the TTM2 trial

Background: The routine use of sedation and analgesia during post-cardiac arrest care and its association with clinical outcomes remain unclear. This study aimed to describe the use of sedatives and analgesics in post-cardiac arrest care, and evaluate associations with good functional outcome, survival, clinical seizures, and late awakening. Methods: This was a post hoc analysis of the TTM2-trial,

A cross-correlator-based timing tool for FemtoMAX

We report on the commissioning of an ultrafast timing diagnostic for measuring a time-offset signal between two different synchronized ultrashort light pulses. The method is based on sum-frequency generation in a nonlinear crystal. The setup is similar to an auto/cross-correlator setup. In this case, one of the beams is a relatively weak diagnostic beam of visible light from a bending magnet at Fe

Josephson vortices and persistent current in a double-ring supersolid system

We theoretically investigate the properties of ultracold dipolar atoms in radially coupled, concentric annular traps created by a potential barrier. The nonrotating ground-state phases are investigated across the superfluid-supersolid phase transition, revealing a particle imbalance between the two rings and a preferential density modulation in the outer ring in the absence of rotation. Near the p

IDAC-Dose 2.2, an internal dosimetry software for diagnostic nuclear medicine based on the latest ICRP adult and paediatric reference computational phantoms

Background: For patients investigated with radiopharmaceuticals, it is important to be able to perform valid calculations of the absorbed dose in organs and tissues. An internal dosimetry computer program, IDAC-Dose2.1, has been updated to be based on the ICRP specific absorbed fractions and computational framework of internal dose assessment for 12 adult and paediatric reference individuals given

CEASA : Dominant spatial autocorrelation in dual-constraint calibration as the game-changer for hydrological modeling with high-uncertainty remotely sensed evaporation: Application to the Meichuan basin

Accurate evapotranspiration (ET) estimation is vital for hydrological modeling, yet remotely sensed ET (RS-ET) products are often limited by algorithmic uncertainties and sensor biases. To mitigate error propagation and better capture spatial patterns, this study introduces the Composite Efficiency of Absolute ET and Spatial Autocorrelation (CEASA) —a dual-constraint framework that integrates abso

Co-adsorption of p-mercaptobenzoic acid on silver nanoparticles enhances the plasmon-mediated coupling reaction of p-ethynylaniline

The enhancement of the electromagnetic field elicited by localized surface plasmon resonance (LSPR) is conducive to the generation of charge carriers, which have an important effect in driving many kinds of chemical reactions. Nonetheless, the short lifespan of charge carriers generated by plasmon (typically femtoseconds to nanoseconds) limits their effectiveness in promoting chemical reactions. H

Is the audience gender-blind? Smaller attendance in female talks highlights an imbalanced visibility in academia

Diverse perspectives are essential to the advancement of biodiversity science, yet persistent structural biases continue to shape who is seen and heard in academic spaces. Despite efforts to promote inclusivity, it remains unclear whether increased representation translates into equitable visibility and engagement from peers. Seminar talks, key arenas for idea exchange and networking, offer a wind
