C-cell hyperplasia in sporadic and familial medullary thyroid carcinoma

Indian Journal of Pathology and Microbiology, 2018
Context: C-cell hyperplasia (CCH) is characterized by increased mass of C-cells and has been identified as a precursor condition for medullary thyroid carcinoma (MTC). Varying proportion of MTCs is associated with CCH in different studies.

False positive results using calcitonin as a screening method for medullary thyroid carcinoma

Indian Journal of Endocrinology and Metabolism, 2013
The role of serum calcitonin as part of the evaluation of thyroid nodules has been widely discussed in literature. However there still is no consensus of measurement of calcitonin in the initial evaluation of a patient with thyroid nodule.

Recurrent hemorrhage risk associated with medial target medullary artery anastomosis from the periventricular collateral vessel in adult patients with moyamoya disease

BMC Neurology, 2021
Background Although the association between periventricular target collateral anastomosis and recurrent ipsilateral hemorrhage has been evaluated in adult patients with moyamoya disease (MMD), no studies have investigated the relationship between target ...

CD44 impacts glomerular parietal epithelial cell changes in the aged mouse kidney

Physiological Reports, 2020
CD44 contributes to the activation of glomerular parietal epithelial cells (PECs). Although CD44 expression is higher in PECs of healthy aged mice, the biological role of CD44 in PECs in this context remains unclear.

Strategies that improve renal medullary oxygenation during experimental cardiopulmonary bypass may mitigate postoperative acute kidney injury.

Kidney International, 2019
Renal medullary hypoxia may contribute to cardiac surgery-associated acute kidney injury (AKI). However, the effects of cardiopulmonary bypass (CPB) on medullary oxygenation are poorly understood.

The ventrolateral medulla and medullary raphe in sudden unexpected death in epilepsy

Brain : a journal of neurology, 2018
Pathological changes in brainstem respiratory nuclei may underlie SUDEP. In this post-mortem study, Patodia et al. reveal alterations in pre-Bötzinger region neurons and modulatory medullary neuropeptidergic and monoaminergic systems, including galanin ...

Continuous bladder urinary oxygen tension as a new tool to monitor medullary oxygenation in the critically ill

Critical Care, 2022
Acute kidney injury (AKI) is common in the critically ill. Inadequate renal medullary tissue oxygenation has been linked to its pathogenesis. Moreover, renal medullary tissue hypoxia can be detected before biochemical evidence of AKI in large mammalian ...
