PER CURIAM.
Iowa inmate Spencer Pierce appeals the district court’s adverse grant of summary judgment in his 42 U.S.C. § 1983 action. Upon careful de novo review, see Johnson v. Blaukat, 453 F.3d 1108, 1112 (8th Cir.2006), we find no basis for reversal. Accordingly, we affirm. See 8th Cir. R. 47B. . The Honorable James E. Gritzner, Chief Judge, United States District Court for the Southern District of Iowa.
