Incidental nanoparticle characterisation in industrial settings to support risk assessment modelling.

Research on nanoparticle (NP) release and potential exposure can be assessed through experimental field campaigns, laboratory simulations, and prediction models. However, risk assessment models are typically designed for manufactured NP (MNP) and have not been adapted for incidental NP (INP) properties. A notable research gap is identifying NP sources and their chemical, physical, and toxicological properties, especially in real-world settings.

SABR tolerance after prostatectomy: pushing the boundaries of ultrahypofractionation.

Objective: To evaluate the feasibility and tolerance of ultra-hypofractionated SABR (stereotactic ablative radiation therapy) protocol following radical prostatectomy.

Patients And Methods: We included patients undergoing adjuvant or salvage SABR between April 2019 and April 2023 targeting the surgical bed and pelvic lymph nodes up to a total dose of 36.25 Gy (7.

Detection of selected vector-borne pathogens in domestic animals, ectoparasites, and their owners in a rural community in Southwest Guatemala.

Vector-borne pathogens, which are transmitted by blood-feeding arthropods to animals and people, are common in tropical regions where, combined with economic factors, can cause significant public health burden. A community-level study was undertaken in southwestern Guatemala to assess the presence of vector-borne pathogens in blood samples from humans (n = 98), their animals (n = 90), and ectoparasites (n = 83) over a period of 2 weeks. Human capillary blood was collected from participant's index finger, and animal venous blood (chickens, pigs, dogs, and cats) was collected from the jugular or cephalic veins at the enrollment period of a concurrent study.

Dynamic Outlier Slicing Allows Broader Exploration of Adaptive Divergence: A Comparison of Individual Genome and Pool-Seq Data Linked to Humic Adaptation in Perch.

How genetic variation contributes to adaptation at different environments is a central focus in evolutionary biology. However, most free-living species still lack a comprehensive understanding of the primary molecular mechanisms of adaptation. Here, we characterised the targets of selection associated with drastically different aquatic environments-humic and clear water-in the common freshwater fish, Eurasian perch (Perca fluviatilis).

Staged thoracoscopic internal traction approach for early repair of long-gap esophageal atresia (LGEA) with distal tracheoesophageal fistula (TEF).

Background: Long-gap esophageal atresia (LGEA) can complicate the management of esophageal atresia (EA) with or without a tracheoesophageal fistula (TEF). This series describes a short interval, staged, thoracoscopic internal traction approach for LGEA with distal TEF to manage complex anastomotic tension or an anatomically impossible esophageal anastomosis.

Methods: A retrospective review (2018-2024) was performed across four tertiary centers to identify patients with LGEA and distal TEF, managed with a staged, thoracoscopic internal traction approach.
