Objectives/hypothesis: The objectives were to present a case report of a woman with recurrent disease during consecutive pregnancies and to discuss the diagnosis and management of granular cell tracheal tumors, with particular attention to pregnancy and hyperestrogenic states.
Study Design: Case report and literature review.
Methods: A Medline search and comprehensive review of literature to assess all cases of granular cell tumors of the trachea were compared and collected, with particular attention to individual cases of pregnancy or cases related to the hyperestrogenic state.
Results: Thirty-two cases of granular cell tumors of the trachea were found. Only a few cases related to the hyperestrogenic state were obtained. The case report describes a woman with recurrent disease in subsequent pregnancies during the later stages of pregnancy.
Conclusion: Few cases of granular cell tumors of the trachea have been reported, with even fewer being pregnancy related. The diagnosis and management of these tumors include careful attention to patient symptoms and airway management.

Background: Regenerative medicine researches have shown that mesenchymal stem cells (MSCs) may be an effective treatment method for premature ovarian insufficiency (POI). However, the efficacy of MSCs is still limited.
Purpose: This study aims to explain whether salidroside and MSCs combination is a therapeutic strategy to POI and to explore salidroside-enhanced MSCs inhibiting ferroptosis via Keap1/Nrf2/GPX4 signaling.

Repetitive transcranial magnetic stimulation (rTMS) is acknowledged for its critical role in modulating neuronal excitability and enhancing cognitive function. The dentate gyrus of the hippocampus is closely linked to cognitive processes; however, the precise mechanisms by which changes in its excitability influence cognition are not yet fully understood. This study aimed to elucidate the effects on granule cell excitability and the effects on cognition of high-frequency rTMS in naturally aging mice, as well as to investigate the potential interactions between these two factors.

To investigate the expression pattern of pan-TRK protein in colorectal cancers with NTRK gene fusion and mismatch repair deficient (dMMR) and to analyze its molecular pathological characteristics. A total of 117 dMMR colorectal cancers diagnosed in the Department of Pathology of Henan Provincial People's Hospital, Zhengzhou, China from 2020 to 2023 were collected. Immunohistochemistry (IHC), fluorescence in situ hybridization (FISH) and DNA/RNA-based next-generation sequencing (NGS) were used to detect pan-TRK protein expression and fusion partner genes in tumors, and to further explore the correlation between pan-TRK staining patterns and partner genes.

During the heat treatment of round steel bars, a heated charge in the form of a cylindrically formed bundle is placed in a furnace. This type of charge is a porous granular medium in which a complex heat flow occurs during heating. The following heat transfer mechanisms occur simultaneously in this medium: conduction in bars, conduction within the gas, thermal radiation between the surfaces of the bars, and contact conduction across the joints between the adjacent bars.

Traumatic brain injury (TBI) is one of the primary causes of mortality and disability, with arterial blood pressure being an important factor in the clinical management of TBI. Spontaneously hypertensive rats (SHRs), widely used as a model of essential hypertension and vascular dementia, demonstrate dysfunction of the hypothalamic-pituitary-adrenal axis, which may contribute to glucocorticoid-mediated hippocampal damage. The aim of this study was to assess acute post-TBI seizures, delayed mortality, and hippocampal pathology in SHRs and normotensive Sprague Dawley rats (SDRs).
