Assessing the reliability of measurement instruments and equipment is essential to ensure the accurate tracking of athletes over extended periods, minimizing the measurement errors caused by chance or other factors. However, a less common but equally important analysis is the verification of inter-measurement agreement, which complements the reliability results. To evaluate the intra- and inter-test reliability of an isometric hip adduction strength and asymmetries test in professional soccer players.

Postmortem identification through fingerprints often encounters significant challenges, particularly with damaged epidermal tissue, due to factors such as carbonization, putrefaction, mummification, or saponification. Traditional techniques frequently fall short in cases involving fragile skin, which complicates the collection of clear fingerprint impressions. This study presents and evaluates an adaptive modification of the transillumination technique, integrating it with moistened black volcano powder to enhance fingerprint recovery from compromised postmortem tissue.

Evaluating carbon removal: Integrating technical potential with environmental, social, governance criteria, and sequestration permanence.

iScience

December 2024

KU Leuven, ECOOM, Department of Managerial Economics, Strategy and Innovation, Faculty of Economics and Business, Naamsestraat 69, BE-3000 Leuven, Belgium.

Climate modeling suggests that achieving international climate goals requires a reduction in current CO emissions by over 90%, with any remaining emissions to be addressed through carbon dioxide removal (CDR) solutions. Sixteen CDR strategies are evaluated by integrating technical potential, environmental, social, and governance (ESG) criteria, along with sequestration permanence. This evaluation, conducted by ENGIE's scientific council using an interdisciplinary Delphi panel methodology, proposes a "quality" measure for each technology.

Background: The congenital absence of the left atrial appendage (LAA) is an extremely rare anatomical anomaly, with only 23 cases documented in medical literature. The LAA plays a critical role in thrombus formation, particularly in patients with atrial fibrillation (AF), thus impacting stroke prevention strategies and the management of anticoagulation.

Case Summary: We report a 48-year-old male with a 2-year history of hypertension and prior episodes of tachycardic palpitations, who presented with AF and chest pain.

Microorganisms have co-evolved with a variety of plants and animals, developing complex symbiotic relationships with their hosts and the environment. The diversity of symbionts acquired over time help their hosts to adapt, survive, and evolve more rapidly and efficiently, improving fitness across the lifespan. Understanding these synergistic relationships between humans and their endogenous microbiota may provide valuable information on human physiology and on potential mechanisms associated with the onset of diseases.

Background: Although rare, vaccine-induced thrombotic thrombocytopenia (VITT) following adenoviral vector COVID-19 vaccination is a concerning and often severe adverse effect of vaccination. The generation of high antiplatelet factor 4 antibody titers promotes the formation of immune complexes capable of activating platelets and neutrophils through FcγRIIa.

Objectives: Given that platelet-leukocyte aggregate formation and inflammasome activation are common features of thromboinflammatory diseases, we aimed to evaluate if these are also features of VITT.
