Context.—: Appendiceal goblet cell adenocarcinoma is an uncommon appendiceal neoplasm that is typically diagnosed incidentally to a presentation of acute appendicitis. Over the years, there have been many changes to the histologic evaluation and classification of this neoplasm, culminating in the most recent (2019) World Health Organization recommendations.
Objective.—: To understand the evolution of the concept of "goblet cell" neoplasia in the appendix, we explore a series of cases of goblet cell adenocarcinoma encountered at a county hospital over a 20-year period. We performed a historically informed review of these cases to highlight the significance and blind spots of our current definition and approach to this disease entity.
Data Sources.—: The cases were recovered from the archives of a county hospital (1999-2019). The literature was assembled through PubMed searches on the various names given to "goblet cell" neoplasms since the 1970s. We also refer to standard reference books of gastrointestinal pathology.
Conclusions.—: Frequent and numerous changes in the nomenclature of "goblet cell" lesions of the appendix resulted in considerable confusion regarding the approach to this rare entity, especially pertaining to its grade, as well as to its management in the clinical setting. The newest approach, recommended by the World Health Organization, provides clarity to its pathologic and clinical management. Adherence to these recommendations will improve communication between pathologists, surgeons, and oncologists about the natural history and prognosis of this malignant neoplasm.

Euglena gracilis-derived β-glucan ameliorates particulate matter (PM)-induced airway inflammation by modulating nuclear factor kappa B, mitogen-activated protein kinase, and nuclear factor erythroid 2-related factor 2 signaling pathways in A549 cells and BALB/c mice.

This study aimed to investigate the effects of β-glucan derived from Euglena gracilis (EGB), an edible microalga, on particulate matter (PM)-induced airway inflammation in A549 cells and BALB/c mice. EGB effectively suppressed the mRNA and protein levels of inflammatory cytokines (IL-6, IL-1β, TNF-α, IL-8) and mediators (iNOS, COX-2), while inhibiting the NF-κB and MAPK signaling pathways triggered by PM exposure and reducing nuclear NF-κB levels. Additionally, EGB decreased PM-induced ROS production and increased the protein levels of NRF2 and HO-1, along with genes encoding antioxidant enzymes (catalase, GPx, SOD1), associated with elevated nuclear NRF2 levels.

As sensors in the gut, tuft cells integrate a complex array of luminal signals to regulate the differentiation fate of intestinal stem cells (ISCs), which trigger a loop of tuft cell-ISC-goblet cell after parasitic infection. As a plant-derived alkaloid, Matrine plays a prominent role for standardizing ISC functions in Eimeria necatrix (EN)-exposed chicks. In this study, we investigated the modulation effects of Matrine on the specific intestinal epithelial cell loop in EN-exposed chicks in vivo and intestinal organoids (IOs) ex vivo.

The aim of this study was to elucidate the impact of porcine pancreatic enzymes (Creon pancrelipase) in comparison to microbial-derived alpha amylase (MD amylase) on the small intestine wall structure, mucosal glycogen accumulation, and enterocyte turnover. The impact of enzyme supplementation on the small intestine was explored in 18 pigs with surgically induced exocrine pancreatic insufficiency (EPI). Four healthy pigs served as the control group.

The aim of this study was to investigate the effects of terpinen-4-ol (TER) supplementation on the intestinal barrier function of pigs. Five groups of fifty 28-day-old piglets with comparable body weights were randomly assigned to the following groups: the control group (CON), the lipopolysaccharide group (LPS), the low TER group (PLT), the middle TER group (PMT), and the high TER group (PHT). The basal diet was given to the CON and LPS groups, and 30, 60, or 90 mg/kg TER was added to the basal diet for the TER groups.
