This case describes a rare presentation of a diffuse large B-cell lymphoma not otherwise specified (DLBC NOS) in the gallbladder. We report the case of an 89-year-old male who initially presented with a two-week history of weakness and abdominal discomfort. We performed laparoscopic cholecystectomy for suspicion of acute cholecystitis. After the initial uneventful course, readmission occurred for persisting weakness a few weeks after surgery. Computed tomography revealed progressive retroperitoneal lymphadenopathy. With new emerging neurological symptoms, taking into account the histopathological findings of the gallbladder specimen, the diagnosis of DLBCL NOS was confirmed. Due to the rapid clinical deterioration and extranodal involvement, the patient opted against further therapy. When the suspicion of cholecystitis is inconclusive, rare differential diagnoses need to be considered. This analysis may improve the understanding of the presentation and course of DLBC NOS in abdominal organs and could form the basis for a systematic review to improve diagnosis and therapy.

A case of cutaneous melanoma metastatic to the ciliary body and choroid with complete regression via systemic dual checkpoint inhibitor therapy.

Background: Cutaneous melanoma is the leading cause of death from cutaneous malignancy and tends to metastasize lymphatically and hematogenously to the lung, liver, brain, and bone; it is a rare source of metastatic disease to the eye. Herein we provide a case report of cutaneous melanoma metastatic to the ciliary body and choroid involving clinical examination, slit lamp photography, and B-scan ultrasonography.
Result: A 55-year-old female with known metastatic cutaneous melanoma presented with pain, a large ciliochoroidal mass, visual decline, and diffuse intraocular inflammation.
YONPs induce selective cytotoxicity, genomic instability, oxidative stress and ROS mediated mitochondrial apoptosis in human epidermoid skin A-431 Cancer cells.

Yttrium oxide nanoparticles (YONPs) have emerged as a promising avenue for cancer therapy, primarily due to their distinctive properties that facilitate selective targeting of cancer cells. Despite their potential, the therapeutic effects of YONPs on human epidermoid skin cancer remain largely unexplored. This study was thus conducted to investigate the impact of YONPs on both human skin normal and cancer cells, with an emphasis on assessing their cytotoxicity, genotoxicity, and the mechanisms underlying these effects.

Antimicrobial resistance refers to the ability of pathogens to develop resistance to drugs designed to eliminate them, making the infections they cause more difficult to treat and increasing the likelihood of disease diffusion and mortality. As such, antimicrobial resistance is considered as one of the most significant and universal challenges to both health and society, as well as the environment. In our research, we employ the explainable artificial intelligence paradigm to identify the factors that most affect the onset of antimicrobial resistance in diversified territorial contexts, which can vary widely from each other in terms of climatic, economic and social conditions.

In this study, we developed an Evidential Ensemble Neural Network based on Deep learning and Diffusion MRI, namely DDEvENet, for anatomical brain parcellation. The key innovation of DDEvENet is the design of an evidential deep learning framework to quantify predictive uncertainty at each voxel during a single inference. To do so, we design an evidence-based ensemble learning framework for uncertainty-aware parcellation to leverage the multiple dMRI parameters derived from diffusion MRI.

Accurately modeling the deformation of temperate glacier ice, which is at its pressure-melting temperature and contains liquid water at grain boundaries, is essential for predicting ice sheet discharge to the ocean and associated sea-level rise. Central to such modeling is Glen's flow law, in which strain rate depends on stress raised to a power of = 3 to 4. In sharp contrast to this nonlinearity, we found by conducting large-scale, shear-deformation experiments that temperate ice is linear-viscous ( 1.
