Intranodular and perinodular ultrasound radiomics distinguishes benign and malignant thyroid nodules: a multicenter study.
Gland Surg
December 2024
Department of Radiology, Ordos Central Hospital, Ordos, China.
Background: Ultrasound based radiomics prediction model can improve the differentiation ability of benign and malignant thyroid nodules to avoid overtreatment. This study evaluates the role of predictive models based on intranodular and perinodular ultrasound radiomics in distinguishing between benign and malignant thyroid nodules.
Methods: A total of 1,076 thyroid nodules were enrolled from three hospitals between 2016 and 2022, forming the training, validation and test cohorts.
A Case Report of an Immature Pituitary-Specific Transcription Factor 1 (PIT1)-Lineage Pituitary Neuroendocrine Tumor Along With Its Cytology and Ultrastructural Studies.

Immature pituitary-specific transcription factor 1 (PIT1)-lineage pituitary neuroendocrine tumors are composed of PIT1-lineage cells with cytological atypia and limited differentiation. These tumors are rare and no cytological features of this neoplasm have been reported. This study is the first to report the cytological features of an immature PIT1-lineage tumor.

Thyroid gland which is responsible for the maintenance of metabolism and growth is derived from thyroglossal duct, an outpocketing of foregut. The microscopic study of thyroid gland during development in first, second and third trimesters has utmost significance to understand the several developmental thyroid disorders metabolically and structurally. This study is descriptive observational study carried in tissue sections taken from thyroid gland of still birth and spontaneously aborted human fetuses of first, second and third trimester.

Department of Medicine, Federal University of Lavras, Lavras, Brazil.
Acetylcarvacrol is a semi-synthetic product derived from carvacrol and has known activity against ticks. In vertebrates, the thyroid has been used as a bioindicator in toxicity studies due to its sensitivity to external factors. Thus, the objective of this study was to evaluate the toxic effects of acetylcarvacrol in Wistar rats subjected to repeated dose dermal and oral toxicity tests by means of histopathological analysis of the thyroid.

Background: Thyroid hormone (T3) has an inhibitory effect on tissue/organ regeneration. It is still elusive how T3 regulates this process. It is well established that the developmental effects of T3 are primarily mediated through transcriptional regulation by thyroid hormone receptors (TRs).
