Synthesis of Three-Dimensional Ring Fused Heterocycles by a Selective [4 + 2] Cycloaddition Between Bicyclic Thiazolo 2-Pyridones and Arynes
A selective [4 + 2] cycloaddition reaction of thiazolo-2-pyridones with arynes has been demonstrated. The developed protocol allows rapid access to highly functionalized, structurally complex thiazolo-fused bridged isoquinolones in high yields, which are susceptible to further late-stage functionalization.

Comparison of immunoassay- with mass spectrometry-derived p-tau quantification for the detection of Alzheimer’s disease pathology
Background: Antibody-based immunoassays have enabled quantification of very low concentrations of phosphorylated tau (p-tau) protein forms in cerebrospinal fluid (CSF), aiding in the diagnosis of AD. Mass spectrometry enables absolute quantification of multiple p-tau variants within a single run. The goal of this study was to compare the performance of mass spectrometry assessments of p-tau181, p-
Distinct microRNA Signature and Suppression of ZFP36L1 Define ASCL1-Positive Lung Adenocarcinoma
Achaete-scute family bHLH transcription factor 1 (ASCL1) is a master transcription factor involved in neuroendocrine differentiation. ASCL1 is expressed in approximately 10% of lung adenocarcinomas (LUAD) and exerts tumor-promoting effects. Here, we explored miRNA profiles in ASCL1-positive LUADs and identified several miRNAs closely associated with ASCL1 expression, including miR-375, miR-95–3p/m
Volumetric Lagrangian temperature and velocity measurements with thermochromic liquid crystals
We propose a Lagrangian method for simultaneous, volumetric temperature and velocity measurements. As tracer particles for both quantities, we employ encapsulated thermochromic liquid crystals (TLCs). We discuss the challenges arising from color imaging of small particles and present measurements in an equilateral hexagonal-shaped convection cell of height h = 60 mm and distance between the parall
Sustainable accessibility : last-mile SC challenges and opportunities in B2C renting models
Achieving sustainable development and achieving Agenda 2030 goals requires drastic socio-technical changes, where one of the main challenges is to shift from the dominant linear and transaction-based business logic to a logic of circularity and resource-maximization. In the circular economy era, there are a growing number of actors offering consumers the opportunity to rent products instead of buy
The impact of the great emigration on the Swedish economy
In the half-century before 1914 wages in Sweden advanced from below the West European average to being at a level with those in Britain. This remarkable record has seldom been addressed, but the very rapid concurrent Swedish economic growth is well known. The present article argues that the increase in wages was not only due to industrialisation, but that another major factor was the trans-Atlanti
Health position paper and redox perspectives - Disease burden by transportation noise; Noise, disease, and redox processes
Transportation noise is a ubiquitous urban exposure. In 2018, the World Health Organization concluded that chronic exposure to road traffic noise is a risk factor for ischemic heart disease. In contrast, they concluded that the quality of evidence for a link to other diseases was very low to moderate. Since then, several studies on the impact of noise on various diseases have been published. Also,
Pre- and Postoperative Antioxidant Use, Aryl Hydrocarbon Receptor (AhR) Activation and Clinical Outcome in Different Treatment Groups of Breast Cancer Patients
BACKGROUND: Cancer patients often use antioxidants that may interact with adjuvant treatments. The purpose was to investigate pre- and postoperative antioxidant use in relation to clinicopathological characteristics and prognosis in different breast cancer treatment groups.METHODS AND PATIENTS: Pre- and postoperative antioxidant (vitamin A, C, E, carotenoids, or Q10) or multivitamin use was self-r
Highly efficient eco-friendly sodium titanate sorbents of Cs(i), Sr(ii), Co(ii) and Eu(iii) : synthesis, characterization and detailed adsorption study
Development of useful all-around materials which can quickly and efficiently adsorb radionuclides in response to environmental radioactive contamination is an urgent research objective. In response to this need, our team developed a simple preparation method for stable sodium titanates which can serve as efficient agents for removal of radionuclides from water. With an emphasis on an environmental
Dynamic visual noise has limited influence on the habitat selection and behavioural activity of crustaceans and cephalopods
Environments contain various forms of noise that can interfere with the ability of animal sensory systems to perceive information. One ubiquitous type of visual noise in shallow aquatic habitats is caustic flicker (or caustics), consisting of dynamically moving light patterns caused by the refraction of light when passing through the water's rippling surface. While some teleost fish avoid environm
Revisiting bicoid function : complete inactivation reveals an additional fundamental role in Drosophila egg geometry specification
Introduction: The bicoid (bcd) gene in Drosophila has served as a paradigm for a morphogen in textbooks for decades. Discovered in 1986 as a mutation affecting anterior development in the embryo, its expression pattern as a protein gradient later confirmed the prediction from transplantation experiments. These experiments suggested that the protein fulfills the criteria of a true morphogen, with t
The use and usefulness of point-of-care tests in patients with pharyngotonsillitis – an observational study in primary health care
Background: Rapid antigen detection tests (RADT) for Group A streptococci (GAS) and point-of-care tests for C-reactive protein (CRP) are commonly used in patients with pharyngotonsillitis in Sweden and Denmark although CRP testing is not supported by guidelines. We aimed to describe (1) the proportion of patients tested with RADT and/or CRP, (2) the relation between test results and antibiotic pre
eSoil : A low-power bioelectronic growth scaffold that enhances crop seedling growth
Active hydroponic substrates that stimulate on demand the plant growth have not been demonstrated so far. Here, we developed the eSoil, a low-power bioelectronic growth scaffold that can provide electrical stimulation to the plants' root system and growth environment in hydroponics settings. eSoil's active material is an organic mixed ionic electronic conductor while its main structural component
Randomized open-label trial of semaglutide and dapagliflozin in patients with type 2 diabetes of different pathophysiology
The limited understanding of the heterogeneity in the treatment response to antidiabetic drugs contributes to metabolic deterioration and cardiovascular complications 1,2, stressing the need for more personalized treatment 1. Although recent attempts have been made to classify diabetes into subgroups, the utility of such stratification in predicting treatment response is unknown 3. We enrolled par

Kyrkorum efter branden : var god sitt - i stol eller bänk: samtida sittmöbelförändringar i svenska kyrkor
I våra kyrkor återfinns många av Sveriges mest intressanta kulturhistoriska interiörer som kan följas hundratals år bakåt i tiden. Nya idéer och former för rummets möblering och sittmöbler sker i takt med samhällets utveckling och blir nya fysiska tidslager i kyrkans narrativ. Några av vår tids stora frågeställningar har utgångspunkt i miljö, demokrati, ekonomi och hållbarhet men även arbetsmiljö,
