Bridge Rectifier. A bridge rectifier makes use of four diodes in a bridge arrangement to achieve full-wave rectification. This is a widely used configuration, both with individual diodes wired as shown and with single component bridges where the diode bridge is wired internally.
Symptoms, Treatments, and Prognosis for Papillary Thyroid Carcinoma. Papillary thyroid cancer (also sometimes called papillary thyroid carcinoma) is the most common type of thyroid cancer. You may have even heard your doctor talk about metastatic papillary thyroid cancer (metastatic means that it has spread beyond your thyroid gland). This article will focus on papillary thyroid cancer basics, including papillary thyroid cancer symptoms, treatments, and prognosis.
Anaplastic carcinoma of the thyroid is a less common form of thyroid cancer and is resistant to both surgical resection and radiation; the 5-year survival rate is between 3% and 17%. Anaplastic cells metastasize quickly, invade the trachea and surrounding tissues, and compress vital structures. Medullary cancer is even less common (3% to 4% of thyroid cancers); it originates in the parafollicular cells of the thyroid. Metastasis occurs to the bones, liver, and kidneys if the disease is not treated.
