Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare form of non-Hodgkin T-cell lymphoma diagnosed in patients with a history of breast implants. Most patients develop a periprosthetic effusion at early stages of disease while less common presentations include a palpable mass, severe capsular contracture, lymphadenopathy, or cutaneous erythema. Due to the complex nature of this disease, a multidisciplinary approach is necessary for optimal management, particularly in locally advanced disease or inoperable patients.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a significant public health concern, with its progression to metabolic dysfunction-associated steatohepatitis (MASH) and fibrosis leading to severe outcomes including cirrhosis, hepatocellular carcinoma and liver failure. While obesity and excess energy intake are well established contributors to the development and progression of MASLD, the distinct role of specific macronutrients is less clear. This review examines the mechanistic pathways through which dietary fatty acids and sugars contribute the development of hepatic inflammation and fibrosis, offering a nuanced understanding of their respective roles in MASLD progression.

Objective Thyroid hormones (TH) control a variety of processes in the central nervous system and influence its response to different stimuli, such as ischemic stroke. Post-stroke administration of 3,3',5-triiodo-L-thyronine (T3) has been reported to substantially improve outcomes, but the optimal dosage and time window remain elusive. Methods Stroke was induced in mice by transient middle cerebral artery occlusion (tMCAO) and T3 was administered at different doses and time points before and after stroke.

Purpose: The landiolol and organ failure in patients with septic shock (STRESS-L study) included a pre-planned sub-study to assess the effect of landiolol treatment on inflammatory and metabolomic markers.

Methods: Samples collected from 91 patients randomised to STRESS-L were profiled for immune and metabolomic markers. A panel of pro- and anti-inflammatory cytokines were measured through commercially acquired multiplex Luminex assays and statistically analysed by individual and cluster-level analysis (patient).

Institute of Analytical and Bioanalytical Chemistry, Ulm University, Albert-Einstein-Allee 11, Ulm 89075, Germany.

Mycotoxin contamination in cereals is a global food safety concern. One of the most common mycotoxins in grains is deoxynivalenol (DON), a secondary metabolite produced by the fungi and . Exposure to DON can lead to adverse health effects in both humans and animals including vomiting, dizziness, and fever.

Background: Inhaled corticosteroids (ICS) are recommended treatment for mild asthma. We aimed to update the evidence on the efficacy and safety of ICS-containing regimens, leukotriene receptor antagonists (LTRA), and tiotropium relative to as-needed (AN) short-acting β2-agonists (SABA) in children (aged 6-11 years) and adolescents/adults.

Methods: A systematic review of randomized controlled trials (RCTs) of regular and AN treatment for mild asthma was conducted (CRD42022352384).

Understanding the chemistry of the inert actinide oxo bond in actinyl ions AnO22+ is important for controlling actinide behavior in the environment, during separations, and in nuclear waste (An = U, Np, Pu). The thioether calixarene TC4A (4-tert-butyltetrathiacalix[4]arene) binds equatorially to [AnO2]n+ (An = U, Np) forming a conical pocket that differentiates the two trans-oxo groups. The 'ate' complexes, [A]2[UO2(TC4A)] (A = [Li(DME)2], HNEt3) and [HNEt3]2[NpO2(TC4A)], enable selective oxo chemistry.

Resilience-runtime tradeoff relations for quantum algorithms.

Rep Prog Phys

January 2025

Applied and Computational Mathematics Division, National Institutes of Standards and Technology (NIST), NA, College Park, Maryland, 20737, UNITED STATES.

A leading approach to algorithm design aims to minimize the number of operations in an algorithm's compilation. One intuitively expects that reducing the number of operations may decrease the chance of errors. This paradigm is particularly prevalent in quantum computing, where gates are hard to implement and noise rapidly decreases a quantum computer's potential to outperform classical computers.

January 2025

Biozentrum, University of Basel, Spitalstrasse 41, Basel, Basel-Stadt, 4056, SWITZERLAND.

Activity and autonomous motion are fundamental aspects of many living and engineering systems. Here, the scale of biological agents covers a wide range, from nanomotors, cytoskeleton, and cells, to insects, fish, birds, and people. Inspired by biological active systems, various types of autonomous synthetic nano- and micromachines have been designed, which provide the basis for multifunctional, highly responsive, intelligent active materials.

Advances in the Release of Amide-Containing Molecules.

Chemistry

January 2025

University of Cambridge, Department of Chemistry, Lensfield Road, CB2 1EW, Cambridge, UNITED KINGDOM OF GREAT BRITAIN AND NORTHERN IRELAND.

The ability to release a molecule from a larger construct in a controlled manner is of great importance to produce effective prodrugs, antibody-drug conjugates, and chemical probes. Amides are ubiquitous functional groups and yet methods to utilise them as molecular release handles are seldom reported. This concept article highlights the advances made in amide release strategies and how these approaches have been utilised.

COPD Airway Epithelial Cell-derived Extracellular Vesicles Spread Cellular Senescence via MicroRNA-34a.

Am J Respir Cell Mol Biol

January 2025

National Heart & Lung Institute, Imperial College London, Airway Disease Section, London, United Kingdom of Great Britain and Northern Ireland.

Chronic obstructive pulmonary disease (COPD) is associated with the acceleration of lung aging, and the accumulation of senescent cells in lung tissue. MicroRNA (miR)-34a induces senescence by suppressing the anti-aging molecule, sirtuin-1 (SIRT1). Senescent cells spread senescence to neighbouring and distant cells, favouring COPD progression and its comorbidities.

Methods to quantify germ cell number in human immature testicular tissues are essential to evaluate the impact of chemotherapy exposures and for optimising cryopreservation protocols used in fertility preservation for prepubertal boys. Established quantification methods rely on the presence of round tubules within the tissue. However, round tubular cross sections are limited in human prepubertal testicular tissues, especially when using in vitro culture.
