Article Abstract

The neutron induced fission of U is a very important reaction for nuclear technology applications and for the design of future systems to produce clean and safe energy. In addition, it is used as a reference reaction for neutron cross-section measurements, thus, its cross section is needed with a high accuracy over a wide energy range. In this work, the measurement for the U(n,f) reaction was carried out at the n_TOF facility located at CERN, at experimental area EAR-2. The standard B(n, α) reaction was used as reference, while a setup based on the gaseous Micromegas detectors was implemented for the detection of the fission fragments and α and Li-particles of the two reactions, respectively. In order to determine the thickness of the B sample NRA measurements were carried out at the National Center for Scientific Research "Demokritos".

In patients with advanced urothelial carcinoma who have progressed after platinum-based chemotherapy, enfortumab vedotin (EV) improves overall survival compared to standard chemotherapy. Additionally, for treatment-naïve patients with locally advanced or metastatic urothelial carcinoma, the combination of pembrolizumab and EV demonstrates superior efficacy over platinum-based chemotherapy. Hence, EV becomes a standard treatment option.

Quinolone resistance in from Thai ducks: Mutation analysis of , and genes.

Vet World

July 2025

Department of Farm Resources and Production Medicine, Faculty of Veterinary Medicine, Kasetsart University, Kamphaeng Saen Campus, Nakhon Pathom, 73140 Thailand.

Background And Aim: is a Gram-negative bacterium causing systemic infections in ducks, often treated with quinolones. However, increasing resistance to quinolones poses a threat to effective treatment, and the molecular mechanisms underlying this resistance remain inadequately understood in Thailand. This study aimed to determine the minimum inhibitory concentrations (MICs) of nalidixic acid, ciprofloxacin, and enrofloxacin; identify mutations in the quinolone resistance-determining regions of and ; and detect () genes in isolates from Thai ducks.

Senescence Under the Lens: X-ray vs. Proton Irradiation at Conventional and Ultra-High Dose Rate.

Radiat Res

September 2025

Unité de Recherche en Biologie Cellulaire (URBC), Namur Research Institute for Life Sciences (NARILIS), University of Namur, Namur, Belgium.

Conventional radiotherapy based on X rays is used to treat more than 50% of cancers. Although effective, radiotherapy can damage healthy tissues around the tumor due to the X-ray dose deposition profile, as well as the safety margin needed to compensate for dose uncertainties. A notable side effect is cellular senescence, characterized by the cessation of cell division while maintaining metabolic activity and promoting the secretion of various components, called the senescence-associated secretory phenotype.

A 3-year-old female patient, who had received a liver transplant from her father 1 year previously to treat biliary atresia, was admitted with fever and pancytopenia. History showed Epstein-Barr virus polymerase chain reaction positivity detected in the patient 3 months earlier; the patient received reduced immunosuppression in doses of tacrolimus, and valganciclovir was administered. Physical exa-mination showed lymphadenopathies at the cervical, axillary and inguinal regions with 2 × 2 cm at diameter, splenomegaly of 5 cm, and fever of 39 °C.

Pulmonary chronic graft-versus-host disease (cGVHD), particularly bronchiolitis obliterans syndrome (BOS), is a severe complication of allogeneic haematopoietic stem cell transplantation (allo-HSCT) with significant morbidity and mortality. This report, developed collaboratively by experts from the Taiwan Society of Blood and Marrow Transplantation (TBMT) and the Taiwan Society of Pulmonary and Critical Care Medicine (TSPCCM), provides consensus statements for the diagnosis, surveillance and management of pulmonary cGVHD. Early detection through pulmonary function tests (PFTs) is critical, with serial monitoring recommended after allo-HSCT.
