Oxygen traces impact on biological methanation from hydrogen and CO.

Biomethane production from biological methanation of CO is promising both for biogas upgrading and surplus renewable energy storage. One of the questions for process upscaling is the impact of oxygen (in the biogas or in the purified CO-rich off-gas) on the biological process. An adapted anaerobic thermophilic consortium was submitted to increasing amounts of oxygen in batch and continuous tests at partial pressures ranging from 0 to 50 mbar.

Feasibility and preliminary efficacy of a physical activity intervention in adults with lymphoma undergoing treatment.

Background: To determine the feasibility, acceptability, and preliminary efficacy of a 6-month tailored non-linear progressive physical activity intervention (PAI) for lymphoma patients undergoing chemotherapy.

Methods: Patients newly diagnosed with lymphoma (non-Hodgkin (NHL) or Hodgkin (HL)) were randomized into the PAI or healthy living intervention (HLI) control (2:1). Feasibility was assessed by examining accrual, adherence, and retention rates.

BRCA1 and BRCA2 mutations testing in prostate cancer: Detection in formalin fixed paraffin embedded (FFPE) and blood samples.

Prostate cancer (PC) represents one of the leading causes of cancer-related morbidity and mortality in men, requiring further understanding to improve diagnosis and treatment. Germline BRCA1/2 mutations, primarily identified in other hereditary cancers, confer an increased risk of developing PC; thus, testing is essential to assess cancer risk, guiding preventive strategies and screening. Recently, somatic BRCA1/2 mutations have emerged as pivotal predictive biomarkers of responsiveness to the poly ADP-ribose polymerase (PARP) inhibitors.

High Incidence of Isolated Tumor Cells in Sentinel Node Biopsies of Thin Melanomas: A Potential Factor in the Paradoxical Prognosis of Stage IIIA Cutaneous Melanoma?

: This study aims to evaluate whether the presence of isolated tumor cells (ITCs) correlates with specific stages of cutaneous melanoma, potentially shedding light on their prognostic significance and the paradoxical survival outcomes in stage IIIA. : This study analyzed cases of sentinel lymph node biopsies for cutaneous melanoma between 2021 and 2023. It included patients with CM diagnoses, available histological slides, and clinical information about the neoplasia stage.

Quantum state processing through controllable synthetic temporal photonic lattices.

Quantum walks on photonic platforms represent a physics-rich framework for quantum measurements, simulations and universal computing. Dynamic reconfigurability of photonic circuitry is key to controlling the walk and retrieving its full operation potential. Universal quantum processing schemes based on time-bin encoding in gated fibre loops have been proposed but not demonstrated yet, mainly due to gate inefficiencies.
