Chronic Stress Promotes Gastric Cancer Metastasis by Inducing Microbiota‐Associated Kynurenine Accumulation and Macrophage Remodeling

open access: yesAdvanced Science, EarlyView.
Chronic stress reshapes the gut microbiota and enriches Lactobacillus reuteri, promoting microbiota‐associated kynurenine accumulation through altered tryptophan metabolism. Kynurenine drives immunosuppressive remodeling of tumor‐associated macrophages through TNFR2–C/EBPβ signaling, thereby enhancing gastric cancer dissemination.

Clinical and genetic aspects of familial isolated pituitary adenomas

open access: yesClinics, 2012
Pituitary adenomas represent a group of functionally diverse neoplasms with relatively high prevalence in the general population. Most occur sporadically, but inherited genetic predisposing factors are increasingly recognized. Familial isolated pituitary

A Recessive Mutation Resulting in a Disabling Amino Acid Substitution (T194R) in the LHX3 Homeodomain Causes Combined Pituitary Hormone Deficiency [PDF]

open access: yes, 2012
Background/Aims: Recessive mutations in the LHX3 homeodomain transcription factor gene are associated with developmental disorders affecting the pituitary and nervous system. We describe pediatric patients with combined pituitary hormone deficiency (CPHD)

A Hybrid Transfer Learning Framework for Brain Tumor Diagnosis

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A novel hybrid transfer learning approach for brain tumor classification achieves 99.47% accuracy using magnetic resonance imaging (MRI) images. By combining image preprocessing, ensemble deep learning, and explainable artificial intelligence (XAI) techniques like gradient‐weighted class activation mapping and SHapley Additive exPlanations (SHAP), the ...

Expression of SNAP-25 in human pituitary neoplasms

open access: yesJournal of Neuropathology and Experimental Neurology, 2007
SNAP‐25, a synaptosome associated exocytosis protein of 25 kDa plays an important role in the secretory activity of several endocrine cells. In the present study, we investigated 15 PRL, 10 GH, 5 ACTH, 5 TSH, 15 FSH/LH/ alpha subunit producing, and 5 null cell adenomas.

Gene expression profile analysis of pituitary adenomas developed by HMGA transgenic mice [PDF]

open access: yes, 2008
The High Mobility Group A (HMGA) nonhistone chromatin proteins alter chromatin structure and, thereby, regulate the transcription of several genes by either enhancing or suppressing transcription factors.

A Comparison of Frailty Indices in Predicting Postoperative Outcomes After Endoscopic Sinus Surgery

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Objective To compare the discriminatory performance of the Risk Analysis Index (RAI) and modified Frailty Index‐5 (mFI‐5) in predicting postoperative outcomes following endoscopic sinus surgery (ESS). Study Design Retrospective cohort study. Methods Adult ESS patients were identified from the ACS‐NSQIP database (2005–2020).

North American Delphi Consensus Study on Sinonasal Malignancy Survivorship Care

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Survival for patients with sinonasal cancers has improved over the past decades, but there are no dedicated survivorship guidelines for this cohort. Objective To understand experts’ priorities and perspectives on key survivorship tenets (surveillance, second tumor screening, toxicity, and symptom management).
