Exploring the role of multimodal [F]F-PSMA-1007 PET/CT and multiparametric MRI data in predicting ISUP grading of primary prostate cancer.

Purpose: The study explores the role of multimodal imaging techniques, such as [F]F-PSMA-1007 PET/CT and multiparametric MRI (mpMRI), in predicting the ISUP (International Society of Urological Pathology) grading of prostate cancer. The goal is to enhance diagnostic accuracy and improve clinical decision-making by integrating these advanced imaging modalities with clinical variables. In particular, the study investigates the application of few-shot learning to address the challenge of limited data in prostate cancer imaging, which is often a common issue in medical research.

International myeloma working group immunotherapy committee recommendation on sequencing immunotherapy for treatment of multiple myeloma.

T-cell redirecting therapy (TCRT), specifically chimeric antigen receptor T-cell therapy (CAR T-cells) and bispecific T-cell engagers (TCEs) represent a remarkable advance in the treatment of multiple myeloma (MM). There are several products available around the world and several more in development targeting primarily B-cell maturation antigen (BCMA) and G protein-coupled receptor class C group 5 member D (GRPC5D). The relatively rapid availability of multiple immunotherapies brings the necessity to understand how a certain agent may affect the safety and efficacy of a subsequent immunotherapy so MM physicians and patients can aim at optimal sequential use of these therapies.

Stromal architecture and fibroblast subpopulations with opposing effects on outcomes in hepatocellular carcinoma.

Dissecting the spatial heterogeneity of cancer-associated fibroblasts (CAFs) is vital for understanding tumor biology and therapeutic design. By combining pathological image analysis with spatial proteomics, we revealed two stromal archetypes in hepatocellular carcinoma (HCC) with different biological functions and extracellular matrix compositions. Using paired single-cell RNA and epigenomic sequencing with Stereo-seq, we revealed two fibroblast subsets CAF-FAP and CAF-C7, whose spatial enrichment strongly correlated with the two stromal archetypes and opposing patient prognosis.

Comparative Population Genetics of Two Alvinocaridid Shrimp Species in Chemosynthetic Ecosystems of the Western Pacific.

Deep-sea shrimps from the family Alvinocarididae are prominent inhabitants of chemosynthesis-based habitats worldwide. However, their genetic diversity and population connectivity remain poorly understood due to limited sampling. To fill these knowledge gaps, we compared the population genetics of two vent- and seep-dwelling alvinocaridid species with overlapped geographic ranges between the South China Sea and the Manus Basin.

IL-21 signaling promotes IgM B cell proliferation and antibody production via JAK/STAT3 and AKT pathways in early vertebrates.

IL-21 is a type I cytokine that is produced by activated CD4 T cells and has a significant impact on the growth, survival, and functional activation of B lymphocytes. While IL-21 has been identified in several teleost fish species, its function and associated mechanisms focus on teleost fish B cells remain largely unknown. In this study, we aimed to investigate the effects of IL-21 (OnIL-21) on IgM B cells from Nile tilapia (Oreochromis niloticus), as well as the intracellular signaling transduction pathway involved.
