A raridade histológica no câncer da tireoide The histological rarity of thyroid cancer

Brazilian Journal of Otorhinolaryngology, 2012
O câncer da tireoide é a neoplasia endócrina mais comum, correspondendo a cerca de 1% de todos os tipos de câncer. Sarcomas, linfomas e metástases para a glândula tireoide são raros e pouco descritos na literatura.

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 ...

An Intact Kidney Slice Model to Investigate Vasa Recta Properties and Function in situ [PDF]

, 2012
Background: Medullary blood flow is via vasa recta capillaries, which possess contractile pericytes. In vitro studies using isolated descending vasa recta show that pericytes can constrict/dilate descending vasa recta when vasoactive substances are ...

Sympathetic nerve-derived ATP regulates renal medullary blood flow via vasa recta pericytes [PDF]

, 2013
Pericyte cells are now known to be a novel locus of blood flow control, being able to regulate capillary diameter via their unique morphology and expression of contractile proteins. We have previously shown that exogenous ATP causes constriction of vasa

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.

The medullary microcirculation

Kidney International, 1987
Like other regional circulations, the medullary circulation supplies oxygen and other primary substrates to the medulla and removes carbon dioxide and other waste metabolites. It also acts as a countercurrent exchanger and simultaneously removes water reabsorbed from the renal tubule to preserve mass balance.

A Case of Mixed Medullary and Follicular Cell Carcinoma of the Thyroid [PDF]

, 2011
A medullary thyroid carcinoma is a malignant tumor derived from the C-cells of the thyroid. Despite their distinct embryological origin, medullary thyroid carcinomas are exceptionally accompanied by a tumor derived from the follicular cells; this is ...

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 ...

Further Characterization of Dopamine Release by Permeabilized PC 12 Cells [PDF]

, 1987
Rat pheochromocytoma cells (PC 12) permeabilized with staphylococcal α-toxin release [3H]dopamine after addition of micromolar Ca2+. This does not require additional Mg2+-ATP (in contrast to bovine adrenal medullary chromaffin cells).

Role of 20-hydroxyeicosatetraenoic acid in mediating hypertension in response to chronic renal medullary endothelin type B receptor blockade. [PDF]

PLoS ONE, 2011
The renal medullary endothelin (ET-1) system plays an important role in the control of sodium excretion and arterial pressure (AP) through the activation of renal medullary ET-B receptors.
