Iowa inmate Paul Close appeals the district court’s 1 adverse grant of summary judgment in his 42 U.S.C. § 1983 action. After careful de novo review, see Turner v. Honeywell Fed. Mfg. & Techs., LLC, 336 F.3d 716, 719-20 (8th Cir. 2003) (de novo *640 review standard), we conclude that summary judgment was properly granted. Accordingly, we affirm. See 8th Cir. R. 47B.
