Long‐Term Particulate Matter Exposure May Increase Risk of Chronic Rhinosinusitis WIth Nasal Polyposis: Results from an Exposure‐Matched Study

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Particulate matter ⩽2.5 µm in diameter (PM2.5) and its role in chronic rhinosinusitis (CRS) pathogenesis have gained heightened attention. We previously demonstrated that PM2.5 exposure may bias the nasal mucosa in CRS toward a Type 2 inflammatory pathway.

A Hierarchical Transformer Encoder to Improve Entire Neoplasm Segmentation on Whole Slide Image of Hepatocellular Carcinoma [PDF]

arXiv, 2023
In digital histopathology, entire neoplasm segmentation on Whole Slide Image (WSI) of Hepatocellular Carcinoma (HCC) plays an important role, especially as a preprocessing filter to automatically exclude healthy tissue, in histological molecular correlations mining and other downstream histopathological tasks.

Functional Characteristics of Multipotent Mesenchymal Stromal Cells from Pituitary Adenomas

Stem Cells International, 2016
Pituitary adenomas are one of the most common endocrine and intracranial neoplasms. Although they are theoretically monoclonal in origin, several studies have shown that they contain different multipotent cell types that are thought to play an important ...

Stability and Hopf bifurcation analysis of a four-dimensional hypothalamic-pituitary-adrenal axis model with distributed delays [PDF]

, 2017
A four-dimensional mathematical model of the hypothalamus-pituitary-adrenal (HPA) axis is investigated, incorporating the influence of the GR concentration and general feedback functions. The inclusion of distributed time delays provides a more realistic modeling approach, since the whole past history of the variables is taken into account.

Oral paltusotine, a nonpeptide selective somatostatin receptor 2 agonist: Mass balance, absolute bioavailability and metabolism in healthy participants

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aims Paltusotine is a novel, nonpeptide, selective somatostatin receptor 2 agonist in development for the treatment of acromegaly and carcinoid syndrome. This study investigated the mass balance, routes of excretion, absolute bioavailability and metabolite profile of orally administered paltusotine.

Markers for internal neoplasia in the horse

Veterinary Medicine and Science, Volume 9, Issue 1, Page 132-143, January 2023., 2023
The measurement of tumour markers in horses should be performed only in risk groups or in patients with suspicious clinical/laboratory findings (paraneoplastic syndromes). The results should be interpreted with caution as many factors (e.g., young age, pregnancy and inflammation) affect their concentration or activity.

Ghost cells: A journey in the dark…

Dental Research Journal, 2012
Ghost cells have been a topic of controversy since a long time. The appearance of these cells in different lesions has given it varying terms. In lesions like that of Calcifying cystic odontogenic tumor (CCOT), these cells have been termed as ′Ghost ...

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

BMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).
