Liver tumors rank as the fourth most common cause of cancer. This case report highlights a 45-year-old female patient who presented persistent abdominal pain and no other symptoms. Initially, she was approached with a probable hepatitis of unknown origin, but her condition worsened rapidly. An endoscopic ultrasound was used to characterize the lesion, and a fine needle biopsy of the lesion was performed which revealed a diffuse large B-cell lymphoma that is CD20+ and Ki67+. Hepatic diffuse large B-cell lymphoma, as diagnosed in the patient, is a rare type of lymphoma that arises in the liver. The treatment usually involves chemotherapy, immunotherapy, and radiation therapy. However, the prognosis depends on the stage of the disease and the patient's overall health. This case reinforces the importance of considering hepatic diffuse large B-cell lymphoma in differential diagnosis for primary liver neoplasia.

The knowledge of diffusion mechanisms in materials is crucial for predicting their high-temperature performance and stability, yet accurately capturing the underlying physics like thermal effects remains challenging. In particular, the origin of the experimentally observed non-Arrhenius diffusion behavior has remained elusive, largely due to the lack of effective computational tools. Here we propose an efficient ab initio framework to compute the Gibbs energy of the transition state in vacancy-mediated diffusion including the relevant thermal excitations at the density-functional-theory level.

Methods: Eighty rheumatoid arthritis (RA) patients and forty healthy controls were included in this case-control study. Of these patients, forty had ILD, and forty without ILD.

Pigment particles used in tattooing may exert long terms effect by releasing diffusible degradation products. In the present work, aqueous suspensions of the organic orange diazo pigment PO13 were aged by exposure to simulated sunlight at 40 °C. The morphology and the surface charge of PO13 particles were barely modified upon aging, but primary particles were released by de-agglomeration.

Aneurysm rupture is a life-threatening event, yet its underlying mechanisms remain largely unclear. This study investigated the fracture properties of the thoracic aneurysmatic aorta (TAA) using the symmetry-constraint Compact Tension (symconCT) test and compared results to native and enzymatic-treated porcine aortas' tests. With age, the aortic stiffness increased, and tissues ruptured at lower fracture energy [Formula: see text].

Superdiffusion is surprisingly easily observed even in systems without the integrability underpinning this phenomenon. Indeed, the classical Heisenberg chain-one of the simplest many-body systems, and firmly believed to be nonintegrable-evinces a long-lived regime of anomalous, superdiffusive spin dynamics at finite temperature. Similarly, superdiffusion persists for long timescales, even at high temperature, for small perturbations around a related integrable model.
