order valproic acid But his lab tests suggest that a mussel-inspired adhesive might prevent or minimize several problems with such fetal surgery. Besides bonding well to tissues, the glue can seal a hole about 3.5 millimeters (0.14 inch, or slightly more than 1/8 inch) across. That???s about the size that a tiny surgical instrument might make. Moreover, artificial glues can inflame tissue. The Northwestern team hopes that mussel-inspired substitutes might avoid this problem. Finally, a mussel glue could be designed to shrink as it warms to body temperature, Messersmith says. That would tend to pull tissues together and possibly speed healing. Right now, he notes, all adhesives and sealants currently approved for use inside the body swell after they???re applied. ??
