Traumatic spinal cord injury(SCI)often leaves patients with devastating neurological deficits.The traumatic event–or primary injury–can be due to mechanisms such as compression,distraction,shear,laceration or(rarely)even transection.Thereafter SCI patients are vulnerable to progressive,delayed damage as a result of secondary insults and secondary injury.Secondary insults such as hypoxia and hypotension occur at the level of the organism from a myriad of causes. 展开更多

Xinjiang Uygur Autonomous Region is a study in contrasts. It is everything you expect and yet nothing like what you expect Spices perfume the air in markets, redolent of chili, cardamom and cumin, with a hint of rose. Colorful mgs are rolled up and stacked upright like boxes of crayons. Brightly colored fabrics hang as they wait to be sewn into garments or curtains. Stacks of beautifully embroidered traditional Uygur caps are balanced on shelves. Carts full of freshly picked grapes and pomegranates dot the streets. The delicious aroma of lamb chunks roasting over open grills is all-consuming. Everywhere there is a whirl of color, from womens outfits to vividly painted and intricately carved doors and trim. 展开更多
