An EGD may be performed therapeutically to control bleeding, remove tumors or polyps (growths), dilate narrowed areas in the upper GI tract (for example, esophagus), remove foreign objects, perform laser therapy, and place a percutaneous gastrostomy tube (a tube used for tube feeding into the stomach).
Navel oranges ripen in the winter and into the spring and early summer, while Valencia oranges begin ripening in the spring and are harvested through the summer. Mandarin Mandarins are more tolerant of cooler temperatures than are many varieties of sweet orange, and they require only moderate heat to ripen well, making them, along with lemons and limes, well suited to northern climates and cool coastal locales.
All oranges ripen on the tree and do not improve in flavor after picked. Valencia orange trees are at peak fruit production when they are 10 to 14 years old, but will continue to give fruit until they reach 20 to 25 years. According to Sunkist growers, âOranges may occasionally 'regreen' in warm weather.
