Update on WASP-19

Tidal interaction between a star and a close-in massive exoplanet causes the planetary orbit to shrink and eventually leads to tidal disruption. Understanding orbital decay in exoplanetary systems is crucial for advancing our knowledge of planetary formation and evolution. Moreover, it sheds light on the broader question of the long-term stability of planetary orbits and the intricate interplay of

Aminoquinoline-based Re(I) tricarbonyl complexes : Insights into their antiproliferative activity and mechanisms of action

In an effort to develop new potent anticancer agents, two Schiff base rhenium(I) tricarbonyl complexes, containing the ubiquitous aminoquinoline scaffold, were synthesized. Both aminoquinoline ligands and Re(I) complexes showed adequate stability over a 48-h incubation period. Furthermore, the cytotoxic activity of the precursor ligands and rhenium(I) complexes were evaluated against the hormone-d

The MSC-EV-microRNAome : A Perspective on Therapeutic Mechanisms of Action in Sepsis and ARDS

Mesenchymal stromal cells (MSCs) and MSC-derived extracellular vesicles (EVs) have emerged as innovative therapeutic agents for the treatment of sepsis and acute respiratory distress syndrome (ARDS). Although their potential remains undisputed in pre-clinical models, this has yet to be translated to the clinic. In this review, we focused on the role of microRNAs contained in MSC-derived EVs, the E

Association of pesticide exposure with neurobehavioral outcomes among avocado farmworkers in Mexico

Background and aim: To date, few studies have focused on the health effects of pesticide exposure among avocado farmworkers. We examined the association of exposure to insecticides, fungicides, and herbicides with cognitive and mental health outcomes among these avocado workers from Michoacan, Mexico. Materials and methods: We conducted a cross-sectional study of 105 avocado farmworkers between Ma

Osteosarcomas With Few Chromosomal Alterations or Adult Onset Are Genetically Heterogeneous

Osteosarcoma is the most common primary bone malignancy, often detected in children and adolescents and commonly associated with TP53 alterations along with a high number of chromosomal rearrangements. However, osteosarcoma can affect patients of any age, and some tumors display less genetic complexity. Besides TP53 variants, data on key driving mutations are lacking for many osteosarcomas, partic

Lojalitetsplikten och 36 § avtalslagen som instrument för krishantering

I denna artikel ställs frågan om inte den lojalitetsplikt, som utmejslats allt tydligare på senare tid genom HD:s praxis och som dessutom blir starkare i tider av kris, tillsammans med 36 § avtalslagens oskälighetsstandard vid ändrade förhållanden, idag kan leda till slutsatsen att det (åtminstone i kristider) föreligger en omförhandlingsskyldighet – vad som skulle kunna kallas ansvar för culpa in

Unraveling the brain's response to COVID-19 : How SARS-CoV-2 afflicts dopaminergic neurons

COVID-19 patients often display dysfunctions of the nervous system, indicating an effect of SARS-CoV-2 on neural cells. Yang et al. now show that human stem-cell-derived dopaminergic neurons are susceptible to SARS-CoV-2, triggering inflammation and senescence. The study further identifies three FDA-approved drugs capable of reversing these cellular phenotypes.

Comparison of immediate anchoring effectiveness of two different techniques of bioresorbable ceramic application for pedicle screw augmentation

Background: The application of a bioresorbable calcium sulfate/hydroxyapatite (CaS/HA) ceramic at the interface of fenestrated screws and osteoporotic bone significantly enhances the immediate mechanical anchorage compared with non-augmented controls. However, the anchoring effectiveness of different screw augmentation techniques in spines with varying vertebral bone mineral density (BMD) remains

Integrated multi-material and multi-scale optimization of compliant structure with embedded movable piezoelectric actuators

Piezoelectric actuators embedded in compliant structures have many potential applications, which call for effective design approaches. Existing optimization driven design methods focus on the piezoelectric actuator location or the macro topology of the host compliant structure while ignoring the possibility to exploit the use of multiple materials and hierarchical material design. In this study, a

Evidence of steady-state fibroblast subtypes in the normal human breast as cells-of-origin for perturbed-state fibroblasts in breast cancer

Background: Human breast cancer most frequently originates within a well-defined anatomical structure referred to as the terminal duct lobular unit (TDLU). This structure is endowed with its very own lobular fibroblasts representing one out of two steady-state fibroblast subtypes—the other being interlobular fibroblasts. While cancer-associated fibroblasts (CAFs) are increasingly appreciated as co

String Interactions as a Source of Collective Behaviour

The discovery of collective effects in small collision systems has spurred a renewed interest in hadronization models, and is also a source for collective effects all the way to large collision systems, where they are usually ascribed to the creation of a Quark–Gluon Plasma. In this topical mini-review, the microscopic model for string interactions, based on the Lund string hadronization model, de

Discerning Progress in Schellenberg's Evolutionary Religion

John L. Schellenberg has suggested that we should guide the evolution of religion towards the goal of discovering the truth about transcendent reality. I argue that we need some way of discerning progress if this project is to be practically feasible. I explore what discernible progress would require in some possible future scenarios. Focus lies on scenarios involving improved cognitive contact wi

Dynamics of anisotropic colloidal systems : What to choose, DLS, DDM or XPCS?

Investigation of the dynamics of colloids in bulk can be hindered by issues such as multiple scattering and sample opacity. These challenges are exacerbated when dealing with inorganic materials. In this study, we employed a model system of Akaganeite colloidal rods to assess three leading dynamics measurement techniques: 3D-(depolarized) dynamic light scattering (3D-(D)DLS), polarized-differentia

Impact of pilot flame and hydrogen enrichment on turbulent methane/hydrogen/air swirling premixed flames in a model gas turbine combustor

This work investigates the impact of pilot flame and fuel composition on the structures and stabilization of swirling turbulent premixed methane/hydrogen/air flames in a lab-scale gas turbine model combustor. Simultaneous measurements of the velocity field and OH radicals distribution in the combustor were conducted using particle imaging velocimetry (PIV) and planar laser-induced fluorescence (PL

Rational and efficient ground investigations for industrialised construction of new railways

To complete a new Swedish railway line in a much shorter timeframe than today, alter natives to the traditional methods need to be explored. One option is the use of prefabricated concrete slabs elevated on piers, analogous to the concept used in China for building new railways in record time (He et al., 2017). The method has the advantage of directly tackling the barrier effects exhibited by trad
