Goblet cell carcinoids (GCC) are extremelyrare neuroendocrine tumours, and characterised by their unique combination of two types of cancer cells âÃÂ" neuroendocrine (carcinoid) and epithelial (adeno-carcinoma). In spite of the fact that GCC is regarded as Neuro-Endocrine Tumour (NET), it does not illicit carcinoid syndrome. GCC usually arises in the appendix and accounting for less than 14% of all appendiceal tumours.Primary extra-appendiceal GCC have been reported as stomach, duodenum, small intestine, colon and rectum. The paper presents a rare case of GCC of the ascending colon in a 57-year-old male.

This study investigated the progressive morphological alterations and digestive tract development in larval and juvenile red spotted grouper, across growth stages. External shape observations were made using an optical microscope, and the development of the digestive tract was investigated using histological methods. At 1 day after hatching (DAH), the digestive tract appeared as a straight tube extending between the ventral side and yolk-sac.

Purpose: Gut microbiota dysbiosis significantly impacts ulcerative colitis (UC) progression and exacerbation. Probiotics show promise in UC management. This study evaluated the effects of different doses of LV149, an aquatic-derived probiotic, on gut injury repair in male C57BL/6 mice with dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) and investigated the underlying mechanisms.

Chemotherapeutic therapies for cancer are frequently associated with cytotoxic side effects that can be harmful to human health, including the development of intestinal mucositis (IM). It mostly affects the gastrointestinal tract, causing ulceration, inflammation, and the formation of lesions in the colon. Surprisingly, despite the frequency of IM, therapeutic choices remain restricted.

Tolerance to dietary antigens is critical for avoiding deleterious type 2 immune responses resulting in food allergy (FA) and anaphylaxis. However, the mechanisms resulting in both the maintenance and failure of tolerance to food antigens are poorly understood. Here we demonstrate that the goblet-cell-derived resistin-like molecule β (RELMβ) is a critical regulator of oral tolerance.

Background: C-type lectin (CTL) plays an important act in parasite adhesion, host's cell invasion and immune escape. Our previous studies showed that recombinant Trichinella spiralis C-type lectin (rTsCTL) mediated larval invasion of enteral mucosal epithelium. The aim of this study was to investigate protective immunity produced by vaccination with rTsCTL and its effect on gut epithelial barrier function in a mouse model.
