A Biochemically “Silent” Aortocaval Paraganglioma in a 19‐Year‐Old Female Causing Intraoperative Hypertensive Crisis: A Rare Case Report

open access: yesClinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Paragangliomas may appear biochemically silent, yet still behave as functional tumors with severe intraoperative consequences. Normal preoperative catecholamine screening does not exclude the risk of hypertensive crisis during surgery.

Primary Neuroendocrine Carcinoma of the Breast: A Diagnostic Challenge and Case Report

open access: yesCancer Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background Primary neuroendocrine carcinoma of the breast (NECB) represents an exceedingly rare entity, comprising less than 0.5% of all breast carcinomas and approximately 1% of all neuroendocrine neoplasms. The 2019 WHO classification defines NECB as tumors expressing neuroendocrine markers in > 90% of tumor cells with morphological features

Survival outcomes and prognostic factors of gastric carcinoma with neuroendocrine differentiation

open access: yesInternational Journal of Cancer, Volume 158, Issue 9, Page 2209-2218, 1 May 2026.
What's new? Although gastric carcinoma with neuroendocrine differentiation (GCNED) is associated with more aggressive features than conventional GC, its prognosis and survival remain poorly defined. To better understand survival patterns, the authors of the present study examined clinicopathological and prognostic features of GCNED patients following ...

Octreotide Counteracts IFN‐γ‐Induced Endothelial Inflammation

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 5, May 2026.
ABSTRACT Endothelial cells maintain vascular homeostasis through the regulation of permeability and coagulation. Interferon‐gamma (IFN‐γ), a proinflammatory cytokine released by activated T lymphocytes and natural killer cells, disrupts endothelial junctional integrity, leading to barrier dysfunction.

Cyclic Peptide Conformational Landscapes Through the Lens of Mass Spectrometry and Orthogonal Spectroscopy

open access: yesJournal of Mass Spectrometry, Volume 61, Issue 5, May 2026.
ABSTRACT Cyclic peptides occupy a structurally dynamic region of chemical space, where function often arises from ensembles rather than a single dominant fold. Closed backbones, frequent N‐methylation, heteroatoms, unnatural amino acids, and a strong propensity for metal coordination create dense conformational and coordination landscapes that ...
