Predicting Risk of Lymph Node Metastasis in Neuroendocrine Carcinoma of Cervix: A Validated Nomogram Incorporating Neuroendocrine Markers and Clinical Parameters

open access: yesCancer Medicine, Volume 15, Issue 3, March 2026.
This study creates a nomogram model to predict risk probability of lymph node metastasis in NECC based on neuroendocrine biomarkers (CD56) and clinical factors. This model is superior to other existing models through the comparison. And it enables clinicians to identify low‐risk patients (risk probability threshold: 0.20) to guide the individualized ...

Acute Intestinal Obstruction Caused by Dual‐Component Metastasis From Combined Small Cell Lung Cancer: A Rare Case and Literature Review

open access: yesClinical Case Reports, Volume 14, Issue 3, March 2026.
ABSTRACT This case report describes a 75‐year‐old male patient who was admitted due to acute intestinal obstruction. The patient had a history of small cell lung cancer. Emergency surgery pathology confirmed the presence of primary composite small cell lung cancer with rare independent dual component metastasis: The colonic lesion was metastatic poorly

Pheochromocytoma With Langerhans Cell Histiocytosis: A Rare Tumor‐in‐Tumor Case

open access: yesClinical Case Reports, Volume 14, Issue 3, March 2026.
ABSTRACT Langerhans cell histiocytosis (LCH) occurring in a Pheochromocytoma in the adrenal gland is exceptionally rare and prone to misdiagnosis. The special coexistent tumors harbor distinct genetic mutations. This uncommon case could introduce novel considerations and a strong teaching message to all the clinicians and pathologists.

Altered DNA Methyltransferase Expression in Pulmonary Large‐Cell Neuroendocrine Carcinoma: Pilot Experimental Data Targeted DNMT1, DNMT3A, and DNMT3B

open access: yesCancer Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Introduction Large cell neuroendocrine carcinoma (LCNEC) is a subtype of non‐small‐cell lung carcinoma with poorly understood methylation characteristics, including the activity of DNA methyltransferases. Despite the pivotal role of DNA methyltransferases in epigenetic regulation, their expression profile in LCNEC remains unexplored.

Chlorogenic Acid Ameliorate Lipopolysaccharide Induced Intestinal Acute Inflammatory Injury via Inhibiting Cytokines Production and Activating Intestinal Stem Cells

open access: yesFood Science &Nutrition, Volume 14, Issue 3, March 2026.
This study aimed to investigate the protective effect and underlying mechanism of CGA in lipopolysaccharide (LPS)‐induced intestinal injury mice. The findings suggest that CGA alleviates intestinal injury by suppressing inflammatory response and preserving ISCs activity via inhibition of the JAK/STAT signaling pathway.

Non‐Functional Paraganglioma of the Urinary Bladder: A Rare Cause of Bladder Tumor

open access: yesIJU Case Reports, Volume 9, Issue 2, March 2026.
ABSTRACT Introduction Paragangliomas of the urinary bladder (PUBs) are rare neuroendocrine tumors, representing less than 0.06% of all bladder neoplasms. While most are functional and associated with catecholamine excess, approximately 15% are non‐functional, often presenting asymptomatically and discovered incidentally.

Oleoylethanolamide regulates intestinal stem cell activity and villus size via PPARα signaling pathway

open access: yesiMetaOmics, Volume 3, Issue 1, March 2026.
First use of a natural swine model with lipid metabolism to directly link lipid differences to a quantifiable intestinal villus height phenotype. Identified the phospholipid‐derived oleoylethanolamide, rather than canonical fatty acids, as the endogenous primary ligand that activates peroxisome proliferator‐activated receptors α (PPARα) to enlarge ...

Mapping Intestinal Paracellular Perm Eability in Mice: Regional and Cellular Variability Under Physiological and Stimulated Conditions

open access: yesFASEB BioAdvances, Volume 8, Issue 3, March 2026.
This study analyzed the paracellular permeability of the intestines of healthy mice at a basal level. A new detection method involving tissue incubation for 5 min with luminal fluorescent dyes, such as FM1‐43FX (FM), which bind to accessible plasma (or external) cell membranes, was developed.
