Detection of BRAF mutation in cytology specimens has been proposed as a diagnostic adjunctive tool in evaluation of thyroid nodules with indeterminate cytology findings. Concurrent papillary thyroid carcinoma and Hashimoto's thyroiditis (HT), a disease characterized by thyroid lymphocytic infiltration, is a frequent occurrence. A large lymphocytic infiltrate might reduce the ...

The steroid hormone aldosterone regulates sodium and potassium homeostasis. Aldosterone and activation of the mineralocorticoid receptor also causes inflammation and fibrosis of the heart, fibrosis and remodelling of blood vessels and tubulointerstitial fibrosis and glomerular injury in the kidney. Aldosterone and mineralocorticoid-receptor activation initiate an inflammatory response by increasing the ...

Cytokinesis is asymmetric along the apical-basal axis of epithelial cells, positioning the midbody near the apical domain. However, little is known about the mechanism and purpose of this asymmetry. We use live imaging of Drosophila follicle cell division to show that asymmetric cytokinesis does not result from intrinsic polarization of ...

BACKGROUND: Recurrent aphthous stomatitis (RAS) is a common oral ulcerative condition. At ulcer sites vascular adhesion molecule-1 (VCAM-1), E-selectin and intercellular adhesion molecule-1 (ICAM-1) are strongly expressed on blood vessels, and ICAM-1 is expressed on keratinocytes. Expression of these molecules would promote leukocyte accumulation and invasion of the epithelium. Thus, ...

Morphological symmetry is a correlate of fitness-related traits or even a direct target of mate choice in a variety of taxa. In these taxa, when females discriminate among potential mates, increased selection on males should reduce fluctuating asymmetry (FA). Hybrid populations of the swordtails Xiphophorus birchmanni and Xiphophorus malinche vary ...
