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

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

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

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

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 ...

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

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

External radiotherapy of thyroid cancer [PDF]
Differentiated thyroid cancer comprises papillary, mixed papillary-follicular and follicular adenocarcinomas. They are mostly hormone-sensitive and respond to thyroid-stimulating hormone (TSH) suppression. The standard treatment is total thyroidectomy. I-

Small cell medullary thyroid carcinoma: A diagnostic dilemma
Small cell variant of medullary thyroid carcinoma (MTC) is a rare variant. In the past, primary thyroid lymphomas were thought to be small cell MTC (SCMTC). However, with the advent of immunohistochemistry, it was realized that SCMTC is rare. Our patient
