AI Article Synopsis
- A 67-year-old man experienced abdominal issues leading to the discovery of a cecal tumor causing bowel obstruction via a CT scan.
- During surgery, multiple nodules were found, and the tumor was diagnosed as poorly differentiated adenocarcinoma with indications of goblet cell carcinoid.
- He was treated with a specific chemotherapy regimen (mFOLFOX6 plus bevacizumab) and lived symptom-free for over a year and a half before ultimately passing away after subsequent treatments failed.
Article Abstract
A 67-year-old man presented with abdominal distention and vomiting.Computed tomography revealed bowel obstruction due to a cecal tumor.We performed laparoscopic ileocecal resection after decompression with an ileus tube. Intraoperative findings included multiple disseminated nodules on the mesenterium surrounding the cecal tumor.The histopathologic diagnosis was poorly differentiated adenocarcinoma, which consisted of glandular proliferation of atypical epithelial cells and dispersed infiltration of goblet cells. Immunohistochemistry showed positively stained neuroendocrine markers, such as CD56, chromogranin, and synaptophysin.The patient was diagnosed with goblet cell carcinoid of the appendix and treated with combination chemotherapy of bevacizumab, fluorouracil, folinic acid, and oxaliplatin.He remained free from progression for over 1 and half years with this treatment.Subsequent chemotherapy was ineffective, and he passed away.There is no established chemotherapy regimen for goblet cell carcinoid, which has the aspects of both adenocarcinoma and neuroendocrine tumors.However, the present case suggested the efficacy of the mFOLFOX6 regimen in combination with bevacizumab for appendiceal goblet cell carcinoid.

Osmoregulation is essential for the survival of aquatic organisms, particularly teleost fish facing osmotic challenges in environments characterized by variable salinity. While the gills are known for ion exchange, the intestine's role in water and salt absorption is gaining attention. Here, we investigated the adaptive responses of the intestine to salinity stress in guppies (), observing significant morphological and transcriptomic alterations.

Purpose: To investigate the presence of uridine-5'-triphosphate (UTP)-activated P2Y1-like nucleotide receptors (P2Y2R, P2Y4R, and P2Y6R) in conjunctival goblet cells (CGCs) and determine if they increase intracellular Ca2+ concentration ([Ca2+]i) and induce mucin secretion.
Methods: Adult, male rat conjunctiva was used for culture of CGCs. To investigate the expression of P2YRs, mRNA was extracted from CGCs and used for reverse transcription PCR (RT-PCR) with commercially obtained primers specific to P2Y2R, P2Y4R, and P2Y6R.

Asthma is a genetically complex inflammatory airway disease associated with over 200 Single nucleotide polymorphisms (SNPs). However, the functional effects of many asthma-associated SNPs in lung and airway epithelial samples are unknown. Here, we aimed to conduct expression quantitative trait loci (eQTL) analysis using a meta-analysis of nasal and lung samples.

Autoimmune enteropathy (AIE) is a rare cause of chronic diarrhea associated with autoantibodies and susceptibility to other autoimmune diseases, such as rheumatoid arthritis, diabetes, autoimmune hemolytic anemia, and atopic dermatitis. While it is more common in children, the prevalence of AIE in adults is increasing. Due to the nonspecific nature of its presenting symptoms and the lack of consistent findings, AIE can be challenging to diagnose.
