Purpose: To compare the quality of DWI images, signal loss of left hepatic lobe and diagnostic performance of apparent diffusion coefficient (ADC) values between SS-EPI and iShim-EPI in liver lesions.
Methods: Totally 142 patients were involved, images using SS-EPI and the prototype iShim-EPI were acquired before injection of gadoxetic acid-enhanced liver MRI.Image quality of demarcation of liver capsule, resolution, lesion distortion, artifacts, lesion confidence score, and signal loss in left hepatic lobe was assessed by two radiologists.

Chemical modifications are widely used in research fields such as quantitative proteomics and interaction analyses. Chemical-modification targets can be roughly divided into four categories, including those that integrate isotope labels for quantification purposes, probe the structures of proteins through covalent labeling or cross-linking, incorporate labels to improve the ionization or dissociation of characteristic peptides in complex mixtures, and affinity-enrich various poorly abundant protein translational modifications (PTMs). A chemical modification reaction needs to be simple and efficient for use in proteomics analysis, and should be performed without any complicated process for preparing the labeling reagent.

Total hepatectomy and liver transplantation has emerged as a game-changing strategy in the treatment of several liver-confined primary or metastatic tumors, opening the new era of transplant oncology. However, the expansion of indications is going to worsen the chronic scarcity of organs, and new strategies are needed to enlarge the donor pool. A possible source of organs could be developing split liver transplantation (SLT) programs.

Clinical benefits of immunotherapy in colorectal cancer (CRC) are limited due to the low immunogenicity and immunosuppressive tumor microenvironment. Fusobacterium nucleatum (Fn) is discovered to colonize CRC tumors and dampen immunotherapy by fostering an immunosuppressive TME. Herein, a controllable "Shielding-deshielding" N-acetylgalactosamine (GalNAc)-derived photothermal nanotherapeutic is developed to mediate cascade targeting toward tumor and intratumoral Fn for enhanced photothermal-immunotherapy.

Two morphologic subtypes of intrahepatic cholangiocarcinoma (iCCA), small duct and large duct, are now recognized, and importantly, these subtypes are associated with distinct molecular pathways and therapeutic options. Initial studies demonstrated the feasibility of morphologic subclassification and helped characterize the immunoprofile of the subtypes. However, few studies have been undertaken in Western countries where incidence of the subtypes is likely distinct from that in the East.
