Morcellation devices in surgery. Laparoscopic morcellation is commonly used at surgery to remove bulky specimens from the abdomen using minimally invasive techniques. Historically, morcellation was performed using a device that required the surgeon or assistant to manually 'squeeze' the handle.
Endocrine functions of the kidneys. The kidneys produce three important hormones: erythropoietin, calcitriol (1,25- dihydroxycholecalciferol) and renin. They also synthesize prostaglandins, which affect many processes in the kidneys.
The two main hormones the thyroid produces and releases are T3 (tri-iodothyronine) and T4 (thyroxine). A thyroid that is functioning normally produces approximately 80% T4 and about 20% T3, though T3 is the stronger of the pair.he two main hormones the thyroid produces and releases are T3 (tri-iodothyronine) and T4 (thyroxine).
