Diagnosis and Treatment of Pituitary Adenomas

open access: yesКреативная хирургия и онкология, 2020
Pituitary adenomas are among the most common primary intracranial tumours. They are predominantly benign and account for 10–15 % of all intracranial neoplasms. These tumours are divided into two subgroups: macroadenomas (> 1 cm) and microadenomas (<

From Multiple Congenital Anomalies to Pituitary Gland Malformation: Wide Spectrum of Clinical Features in a Family With FOXA2 Variant

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT FOXA2 (hepatocyte nuclear factor‐3β, HNF‐3β) encodes a transcriptional activator involved in early embryogenesis, particularly in the patterning and differentiation of midline structures such as the neural tube, foregut, and pituitary gland. Its role in human pathogenesis was first suspected when patients with deletion of chromosome 20p11.2 ...

Altered Nasal Microbiota in Sinonasal Tumors: A Comparative Analysis of Malignant and Benign Sinonasal Tumors

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Although shifts in nasal microbiota have been well‐documented in inflammatory upper airway conditions, microbiota tumor‐associated alterations remain uncharacterized. This study is the first to compare sinonasal microbiota profiles of patients with malignant tumors (MT), benign tumors (BT), and controls, offering insights into tumor‐

Identification and Profiling of Pituitary microRNAs of Sheep during Anestrus and Estrus Stages

open access: yesAnimals, 2020
MicroRNAs (miRNAs) are a class of small non-coding RNAs, molecules of 21 to 25 nucleotides in length, that regulate gene expression by binding to their target mRNA and play a significant role in animal development.
