Grouping of chemicals for safety assessment: the importance of toxicokinetic properties of salicylate esters.

Grouping of chemicals has been proposed as a strategy to speed up the screening and identification of potential substances of concern among the broad chemical universe under REACH. Such grouping is usually based on shared structural features and should only be used for the prioritization objectives. However, additional considerations (as well as structural similarity) are needed, e.

Conceptual foundations of a REFRAME-based approach to discriminate across total knee implant designs based on the positions of functional centres of rotation.

In modern knee arthroplasty, surgeons increasingly aim for individualised implant selection based on data-driven decisions to improve patient satisfaction rates. The identification of an implant design that optimally fits to a patient's native kinematic patterns and functional requirements could provide a basis towards subject-specific phenotyping. The goal of this study was to achieve a first step towards identifying easily accessible and intuitive features that allow for discrimination between implant designs based on kinematic data.

A New Global Mangrove Height Map with a 12 meter spatial resolution.

Mangrove forests thrive along global tropical coasts, acting as a barrier that protects coastlines against storm surges and as nurseries for an entire food web. They are also known for their high carbon sequestration rates and soil carbon stocks. We introduce a new global mangrove canopy height map generated from TanDEM-X spaceborne elevation measurements collected during the 2011-2013 period with a 12-meter spatial resolution and an accuracy of 2.

Phosphorylation of a nuclear condensate regulates cohesion and mRNA retention.

Nuclear speckles are membraneless organelles that associate with active transcription sites and participate in post-transcriptional mRNA processing. During the cell cycle, nuclear speckles dissolve following phosphorylation of their protein components. Here, we identify the PP1 family as the phosphatases that counteract kinase-mediated dissolution.

Background: Non-invasiveness and comfort are crucial in the conservative management of distal radius and scaphoid fractures. While fiberglass casts are standard, three-dimensional (3D)-printed orthoses offer a promising alternative.

Purpose: To compare patient experiences, safety perceptions, and satisfaction between a 3D orthosis and fiberglass cast for distal radius or scaphoid fractures.

Quantifying the effect of particulate impurities on the ice nucleation behavior of pharmaceutical solutions.

Numerous commercially available biopharmaceuticals are frozen or freeze-dried in vials. The temperature at which ice nucleates and its distribution across vials in a batch is critical to the design of freezing and freeze-drying processes. Here we study experimentally how the level of particulate impurities - a key parameter in pharmaceutical manufacturing - affects the ice nucleation behavior.

Single versus Dual Antiplatelet Therapy after Left Atrial Appendage Closure: a Propensity Score Matching Analysis.

Background: Either dual antiplatelet therapy or oral anticoagulation in combination with aspirin represent recommended treatment regimens following left atrial appendage closure (LAAC). As the majority of patients receiving LAAC have high bleeding risk, less aggressive antithrombotic treatments are needed, such as single antiplatelet therapy.

Objectives: To compare both ischemic and bleeding outcomes in patients receiving single (SAPT) or dual antiplatelet therapy (DAPT) after successful LAAC.

Bovine besnoitiosis: Assessment of the diagnostic accuracy of three different tests using a Bayesian latent class model approach and clinical characterization of the disease.

Bovine besnoitiosis, a disease caused by the tissue cyst-forming apicomplexan Besnoitia besnoiti, is re-emerging in Europe, leading to significant impairment of health and production, as well as economic losses. The early detection of the disease is of the utmost importance for the implementation of effective control measures, yet this is a challenge due to the lack of specific early clinical signs. The objectives of our study were 1) to estimate the diagnostic accuracy of three tests to detect B.

E-jet printed polycaprolactone with strontium-substituted mesoporous bioactive glass nanoparticles for bone tissue engineering.

Osteoporosis, characterized by reduced bone mineral density and increased fracture risk, poses a significant health challenge, particularly for aging populations. Systemic treatments often lead to adverse side effects, emphasizing the need for localized solutions. This study introduces a 3D-printed polycaprolactone (PCL) scaffold embedded with strontium-substituted mesoporous bioactive glass nanoparticles (Sr-MBGNPs) and icariin (ICN) for the targeted regeneration of osteoporotic bone.

Legal framework and IVF outcomes: a comparative analysis of fresh and frozen embryo transfers in Switzerland.

Research Question: To what extent do legislative measures impact standard reproductive outcome parameters?

Design: Retrospective cohort study using data from the Swiss national IVF registry analysing the outcomes of 13,908 women undergoing embryo transfers resulting from their first lifetime oocyte retrieval before (2014-2016) or after (2020-2022) revision of the legislation, allowing extended culture for 12 zygotes. Live birth rates (LBR) and cumulative LBR (cLBR) were compared in fresh and frozen embryo transfer strategies in both periods. Adjusted multivariable mixed model analyses were performed to determine OR and incidence rate ratios (IRR).

Electrocatalytic Micelle-Driven Hydrodefluorination for Accessing Unprotected Monofluorinated Indoles.

Toxic organic solvents and electrolytes, traditionally indispensable for electro-organic synthesis, are now being reconsidered. In developing more sustainable electro-organic synthesis, we've harnessed the aqueous micelles as solvents and electrolyte-like structures when deformed under an electric field. The technology is showcased in synthetically highly valued hydrodefluorination reactions of difluorinated indoles.

Borderline personality disorder and moral responsibility.

This paper seeks to determine the extent to which individuals with borderline personality disorders can be held morally responsible for a particular subset of their actions: disproportionate anger, aggressions and displays of temper. The rationale for focusing on these aspects lies in their widespread acknowledgment in the literature and their plausible primary association with blame directed at BPD patients. BPD individuals are indeed typically perceived as "difficult patients" (Sulzer 2015:82; Bodner et al.

Evolution of competitive ability and the response to nutrient availability: a resurrection study with the calcareous grassland herb, Leontodon hispidus.

Rapid environmental changes across Europe include warmer and increasingly variable temperatures, changes in soil nutrient availability, and pollinator decline. These abiotic and biotic changes can affect natural plant populations and force them to optimize resource use against competitors. To date, the evolution of competitive ability in the context of changes in nutrient availability remains understudied.

Rescue therapy after failed thrombectomy in medium/distal vessel occlusions: A retrospective analysis of an international, multi-center registry.

Background: There are limited therapeutic options in cases of failed reperfusion (modified thrombolysis in cerebral infarction [mTICI] score < 2b) after stent-retriever and/or aspiration based endovascular treatment (EVT) for acute ischemic stroke. Despite the absence of data supporting its use, rescue therapy (balloon angioplasty and/or stent implantation) is often utilized in such cases. Studies are limited to large vessel occlusions, while the outcomes and complications after rescue therapy in medium/distal vessel occlusions (MDVOs) have not been reported.

Behind the scenes of EQA-characteristics, capabilities, benefits and assets of external quality assessment (EQA).

The main stakeholders in external quality assessment (EQA) programs are the participants, in whose interests these challenges are ultimately organised. EQA schemes in the medical field contribute to improving the quality of patient care by evaluating the analytical and diagnostic quality of laboratory and point-of-care tests (POCT) by independent third parties and, if necessary, pointing out erroneous measurement results and analytical or diagnostic improvement potential. Other benefits include the option of using EQA samples for other important laboratory procedures, such as the verification or validation of diagnostic medical devices (IVD-MDs), a contribution to the estimation of measurement uncertainty, a means of training and educating laboratory staff through educational EQA programmes or samples, or even for independent and documented monitoring of staff competence, such as on samples with unusual or even exceptional characteristics.

Land Use Change Consistently Reduces α- But Not β- and γ-Diversity of Bees.

Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e.
