Angiogenesis is coordinated with follicular cell growth in goitrogenesis. The angiopoietins, Ang-1 and Ang-2, are angiogenic growth factors acting through Tie-2, a tyrosine kinase receptor. We have examined the expression and regulation of the angiopoietins and Tie-2 in human and rat thyroids. In human goiters there was increased Tie-2 immunostaining, compared with that in normal thyroids, on b...
The odds for success of a future CAI system (as well as the present CAI movement) are completely dependent on the quality of an underlying theory of innovation and the effectiveness of its tools, processes and models. This paper establishes a set of requirements for such a theory, evaluates existing approaches, methodologies and theories (including TRIZ), and presents an overview of the General...
geographic tongue is a benign disorder involving the dorsal surface of the tongue characterized by depapillated areas with leading and folded edges in yellowish or grayish white color and sometimes with unclear borders. many studies have reported a relationship between such condition and different risk factors. this study aimed to investigate the prevalence rate and the risk factors of geograph...
Ample evidence supports that prostate tumor metastasis originates from a rare population of cancer cells, known as cancer stem cells (CSCs). Unfortunately, little is known about the identity of these cells, making it difficult to target the metastatic prostate tumor. Here, for the first time, we report the identification of a rare population of prostate cancer cells that express the Tie-2 prote...
Growth factor receptors in human hematopoietic progenitor cells have become the focus of intense interest, because they may provide tools for the monitoring, enrichment, and expansion of stem cells. We have shown earlier that the Tie receptor tyrosine kinase is expressed in erythroid and megakaryoblastic human leukemia cell lines, in the blood islands of the yolk sac, and in endothelial cells s...
background and objectives: squamous cell carcinoma of the tongue (sccot) is the most common malignant neoplasm in oral cavity. at the time of the diagnosis of sccot regional metastases with a high mortality rate are common, which is due to the extensive lymphatic system drainage of the tongue. although the level of healthcare has significantly improved, the survival rate is still low with an un...
granular cell tumor is a rare benign neoplasm most commonly appears in the head and neck region, especially in the tongue, cheek mucosa, and palate. occurrence in limbs is even rarer. these tumors account for approximately 0.5% of all soft tissue tumors. granular cell tumor can also affect other organs including skin, breast, and lungs. local recurrence and metastasis is potentially higher in m...
