The Role of EPH/Ephrin System in the Pancreas
Pancreatic ductal adenocarcinoma (PDAC) is a major concern for health care systems worldwide, since its mortality remains unaltered despite the surge in cutting-edge science. The EPH/ephrin signaling system was first investigated in the 1980s. EPH/ephrins have been shown to exert bidirectional signaling and cell-to-cell communication, influencing cellular morphology, adhesion, migration and invasion.

Gut Virome in Childhood Diseases
Mammals are colonized by numerous microbes, collectively referred to as the microbiota. The microbiota forms a stable symbiotic relationship with the host and is indispensable for health maintenance. Although the eubacteria are the best characterized component of the human gut microbiota, it also includes commensal populations of viruses, fungi, multicellular parasites and archaea. Evidence highlights that the virome, consisting in DNA and RNA eukaryotic viruses, bacterial viruses (i.e., bacteriophages) and archaeal viruses, exerts a fundamental role in the host wellbeing. Indeed, alterations of the adult virome have been linked to increased disease susceptibility, suggesting that maintaining or restoring a structurally and functionally correct composition of the virome might represent in the near future a promising approach to prevent or cure different human diseases. Although the knowledge of childhood virome is currently very limited, modifications of the virome composition have been associated with several diseases during the pediatric age, such as inflammatory bowel disease, type 1 diabetes, malnutrition, diarrhea and celiac disease.

Epithelial–Mesenchymal Transition in Colorectal Cancer
The epithelial–mesenchymal transition (EMT) is a cellular reprogramming process that occurs during embryonic development and adult tissue homeostasis. This process involves epithelial cells acquiring a mesenchymal phenotype. Epithelial–mesenchymal plasticity (EMP) has become a hot issue in colorectal cancer (CRC) because strong inducers of EMT (such as transforming growth factor β, TGF-β) can initiate EMT and regulate metastasis, micro-environment, and immune system resistance in CRC.

MAFLD and Chronic Viral Hepatitis
Metabolic dysfunction-associated fatty liver disease (MAFLD) has now affected nearly one-third of the global population and has become the number one cause of chronic liver disease in the world because of the obesity pandemic. Chronic hepatitis resulting from hepatitis B virus (HBV) and hepatitis C virus (HCV) remain significant challenges to liver health even in the 21st century. The co-existence of MAFLD and chronic viral hepatitis can markedly alter the disease course of individual diseases and can complicate the management of each of these disorders. A thorough understanding of the pathobiological interactions between MAFLD and these two chronic viral infections is crucial for appropriately managing these patients.

Contribution of Leukocytes in Non-Alcoholic Fatty Liver Disease
Non-alcoholic fatty liver disease (NAFLD) is currently the most prevalent chronic liver disease in Western countries, affecting approximately 25% of the adult population. This condition encompasses a spectrum of liver diseases characterized by abnormal accumulation of fat in liver tissue (non-alcoholic fatty liver, NAFL) that can progress to non-alcoholic steatohepatitis (NASH), characterized by the presence of liver inflammation and damage. Lymphocytes are certainly the most relevant leukocytes of the adaptive immune system.

Microbiota-derived Short-Chain Fatty Acids and Obesity
Microbiota-derived Short-Chain Fatty Acids (SCFAs), primarily acetate, propionate and butyrate, are metabolites produced by gut microbiota via dietary non-digestible carbohydrates (CHO) fermentation. Maternal very low-calorie ketogenic diet (VLCKD) during pregnancy and lactation stimulates the growth of diverse species of SCFA-producing bacteria, which may induce epigenetic changes in infant obese gene expression and modulate adipose tissue inflammation in obesity.

Field of Submucosal Endoscopy
Submucosal endoscopy (third-space endoscopy) can be defined as an endoscopic procedure performed in the submucosal space. This procedure is novel and has been utilized for delivery to the submucosal space in a variety of gastrointestinal diseases, such as a tumor, achalasia, gastroparesis, and subepithelial tumors. The main submucosal endoscopy includes peroral endoscopic myotomy, gastric peroral endoscopic myotomy, Zenker peroral endoscopic myotomy, submucosal tunneling for endoscopic resection, and endoscopic submucosal tunnel dissection. Submucosal endoscopy has been used as a viable alternative to surgical techniques because it is minimally invasive in the treatment and diagnosis of gastrointestinal diseases and disorders.

Fatty Liver Syndrome
Fatty liver syndrome is an emerging health problem in the world, due to the high prevalence of obesity and alcohol use disorder. Given the nature of the disease’s advancement to cirrhosis and liver-related complications, it is important to assess the severity of the disease, which is typically done via a liver biopsy. Due to the limitations and risks of liver biopsy, the role of noninvasive tests is essential and evolving to stratify the stage of the liver disease, predict the outcomes, and/or monitor the treatment response. This review is focused on noninvasive tests, including the use of serum-based biomarkers, ultrasound-based shear wave elastography, transient elastography, and magnetic resonance elastography in both clinical and research settings

Technical Challenges to TIPS and Modifications in Approach
TIPS involves creating an artificial conduit between the hepatic and portal veins to decrease the portal pressure and resolve the associated complications of portal hypertension. The procedure has traditionally been performed under fluoroscopic guidance with or without wedge portography or carbon dioxide angiography to delineate the portal venous branches. In patients with anatomically challenging scenarios such as chronic portal vein thrombosis, traditional TIPS procedure methods may not prove technically successful.

Metabolism-Associated Epigenetic and Immunoepigenetic Re-programming in Liver Cancer
Metabolic reprogramming and epigenetic changes have been characterized as hallmarks of liver cancer. Metabolic intermediates serve as crucial substrates for various epigenetic modulations, from post-translational modification of histones to DNA methylation. In turn, epigenetic changes can alter the expression of metabolic genes supporting on the one hand, the increased energetic demand of cancer cells and, on the other hand, influence the activity of tumor-associated immune cell populations. In this review, we will illustrate the most recent findings about metabolic reprogramming in liver cancer. We will focus on the metabolic changes characterizing the tumor microenvironment and on how these alterations impact on epigenetic mechanisms involved in the malignant progression. Furthermore, we will report our current knowledge about the influence of cancer-specific metabolites on epigenetic reprogramming of immune cells. Finally, we will review the current strategies to target metabolic and epigenetic pathways and their therapeutic potential in liver cancer, alone or in combinatorial approaches.

Apoptosis and Autophagy in Human Colorectal Cancer Development
Colorectal cancer (CRC) remains a major life-threatening malignancy. Apoptosis and autophagy are two processes that share common signaling pathways, are linked by functional relationships and have similar protein components. During the development of cancer, the two processes can trigger simultaneously in the same cell, causing, in some cases, an inhibition of autophagy by apoptosis or apoptosis by autophagy. Malignant cells that have accumulated genetic alterations can take advantage of any alterations in the apoptotic process and as a result, progress easily in the cancerous transformation. Autophagy often plays a suppressive role during the initial stages of carcinogenicity, while in the later stages of cancer development it can play a promoting role. It is extremely important to determine the regulation of this duality of autophagy in the development of CRC and to identify the molecules involved, as well as the signals and the mechanisms behind it. All the reported experimental results indicate that, while the antagonistic effects of autophagy and apoptosis occur in an adverse environment characterized by deprivation of oxygen and nutrients, leading to the formation and development of CRC, the effects of promotion and collaboration usually involve an auxiliary role of autophagy compared to apoptosis.
