MRI has transformed from the theoretical, investigative realm to mainstream clinical medicine over the past four decades and has become a core component of the diagnostic toolbox in the practice of gastroenterology (GI). Its success is attributable to exquisite contrast and the ability to isolate specific proton species through the use of different pulse sequences (i.e., T1-weighted, T2-weighted, diffusion-weighted) and exploiting extracellular and hepatobiliary contrast agents. Consequently, MRI has gained preeminence in various GI clinical applications: liver and pancreatic lesion evaluation and detection, liver transplantation evaluation, pancreatitis evaluation, Crohn's disease evaluation (using MR enterography) rectal cancer staging and perianal fistula evaluation...

In patients with biliary papillomatosis, complete resection of the biliary tree (that is, liver transplant along with duodenocephalo-pancreatectomy) is considered the only potential curative treatment, given its diffuse pattern and likelihood of malignant transformation. Nevertheless, such a combined surgical approach can increase patient morbidity and mortality and should be considered only when the distal part of the common bile duct is involved. Here, we avoided duodenocephalo-pancreatectomy in a patient with distal common bile duct free from disease; this approach did not negatively influence survival and appeared to be safer during liver transplant...

Hydrothorax occurs frequently in patients with endstage liver disease and usually requires drainage of pulmonary effusion during the hepatectomy phase of liver transplant. Reexpansion pulmonary edema is a rare but potentially fatal complication seen after rapid reexpansion of the collapsed lung following thoracentesis of pleural fluid or tube drainage of pneumothorax. This condition, which manifests with various degrees of clinical severity, is rarely reported following liver transplantation. Herein, we present a 62-year-old male patient who developed reexpansion pulmonary edema after drainage of massive pleural effusion, which caused a total collapse in the right hemithorax during liver transplant...

Lipid droplets (LDs) with own interface architecture not only play crucial roles in protecting cell from lipotoxicity and lipoapoptosis but also closely relate with many diseases such as fatty liver and diabetes. Thus, as one of important applied biomaterials, fluorescent probes with ultrahigh selectivity for in-situ and high-fidelity imaging LDs in living cells and tissues are critical to elucidate relevant physiological and pathological events as well as detect related diseases. However, available LDs probes only utilizing their waterless neutral cores but ignoring the unique phospholipid monolayer interfaces exhibit low selectivity...

Primary hepatic lymphoma (PHL) is defined as a lympho-proliferative disorder limited to the liver without any involvement of the spleen, lymph nodes, bone marrow or blood. Diffuse large B-cell lymphoma (DLBCL) is the most common histological type counting more than 60-80% of all PHL. Usually, it occurs in middle-aged men with aspecific symptoms and diagnosis is confirmed by histopathology. In order to expand current knowledge and to investigate an optimal therapeutic strategy, a systematic review of literature was conducted in February 2016...

BACKGROUND: Burkitt lymphoma is a highly aggressive B cell non-Hodgkin lymphoma. Cross-sectional imaging techniques that are used to detect liver and spleen involvement by lymphoma have high rates of false negative and false positive findings, and as such may reduce the accuracy of staging. PURPOSE: This retrospective study evaluated the use of FDG PET-CT in determining splenic involvement at staging, in a relatively large cohort of adult patients with the sporadic form of Burkitt lymphoma (SBL)...

Hepatitis C virus (HCV) infection is widely diffused in general population, and the likelihood that an infected individual is affected by other disesases is high. A lot of epidemiological and explicative studies, even if with different levels of evidence, reported a potential effect of HCV infection -by direct and indirect mechanisms- on the pathogenesis of extrahepatic comorbidities related to dysregulation of the immune system, or cardiometabolic comorbidities like diabetes, neuropsychiatric disorders, chronic kidney disease, cardiovascular alterations, etc...

Heat shock protein 47 kDa (HSP47), an ER-resident and collagen-specific molecular chaperone, recognizes collagenous hydrophobic amino acid sequences (Gly-Pro-Hyp) and assists in secretion of correctly folded collagen. Elevated collagen production is correlated with HSP47 expression in various diseases, including fibrosis and keloid. HSP47 knockdown ameliorates liver fibrosis by inhibiting collagen secretion, and inhibition of the interaction of HSP47 with procollagen also prevents collagen secretion. Therefore, a high-throughput system for screening of drugs capable of inhibiting the interaction between HSP47 and collagen would aid the development of novel therapies for fibrotic diseases...

BACKGROUND: Uveal melanoma accounts for 85% of the ocular melanomas and has an increased risk of hematogenous spread, most commonly to the liver. After curative intent therapy like surgery and radiation, fifty percent of patients present with distant metastasis. Metastatic uveal melanoma (MUM) does not harbor typically targetable mutations, e.g., BRAF as in cutaneous melanoma. As a result, there is no proven therapy for MUM. Various chemotherapy and immunotherapy regimens have been tried and only partial response (PR) is the best that has been achieved in most of the cases...
