Increased diffusion and decreased perfusion in epiphyses of femoral heads detected via intravoxel incoherent motion after closed reduction in children with developmental dysplasia of the hip.

Background Patients with developmental dysplasia of the hip (DDH) may have decreased blood supply to the femoral heads. Finding a non-invasive method to evaluate whether the femoral heads in patients with DDH are ischemic is paramount for orthopedic surgeons. Purpose To identify whether parameters reflecting perfusion and diffusion in intravoxel incoherent motion (IVIM) sequences can be used to assess ischemia in femoral heads in patients with DDH after closed reduction.

Protective potential of the methanol extract of Macrothelypteris oligophlebia rhizomes for chronic non-bacterial prostatitis in rats.

The protective potential of the methanol extract of Macrothelypteris oligophlebia rhizomes (MMO) for chronic non-bacterial prostatitis (CNP) in rats was investigated in the present study. Carrageenan-induced CNP in rats was established. Fifty rats were randomly divided into sham-operated (sham-ope) group, model group, positive control group (Cernilton at a dose of 148mg/kg body weight) and two MMO-treated groups (MMO at doses of 600mg/kg and 300 mg/kg body weight).

Lipoprotein lipase gene polymorphisms and risks of childhood obesity in Chinese preschool children.

Childhood obesity is increasingly prevalent in the community and is related to many adult diseases. Lipoprotein lipase (LPL) plays a central role in dyslipidemia, and polymorphisms of the LPL gene may result in the disturbance in the lipid's metabolism. The aim of this study is to test the hypothesis that genetic variants of LPL and serum lipid levels are associated with the risk of childhood obesity.

Three-dimensional molecular packing of thin organic films of PTCDI-C8 determined by surface X-ray diffraction.

We have determined the full molecular 3D packing of thin organic films of the archetypical organic n-type semiconductor N, N'-dioctyl-3,4:9,10-perylene tetracarboxylic diimide (PTCDI-C 8) by surface X-ray crystallography. We show that PTCDI-C 8 forms smooth layered films on Al 2O 3 (11-20) with an outstanding degree of molecular order. The thin-film structure is found to consist of a triclinic unit cell with the plane of the aromatic core tilted by 67 +/- 2 degrees with respect to the surface plane, which differs significantly from the bulk structure.
