PURPOSE This study aims to compare the biomechanical properties of the novel pedicle screw and plate system with the traditional rod system in asymmetrical posterior stabilization for minimally invasive transforaminal lumbar interbody fusion (MI-TLIF). We compared the immediate stabilizing effects of fusion segment and the strain distribution on the vertebral body. METHODS Seven fresh calf lu...

PURPOSE To demonstrate accelerated imaging with both artifact reduction and different contrast mechanisms near metallic implants. MATERIALS AND METHODS Slice-encoding for metal artifact correction (SEMAC) is a modified spin echo sequence that uses view-angle tilting and slice-direction phase encoding to correct both in-plane and through-plane artifacts. Standard spin echo trains and short-TI ...

To investigate the effect of metal implants in proton radiotherapy, dose distributions of different, clinically relevant treatment plans have been measured in an anthropomorphic phantom and compared to treatment planning predictions. The anthropomorphic phantom, which is sliced into four segments in the cranio-caudal direction, is composed of tissue equivalent materials and contains a titanium ...

Transorbital brain injuries caused by metal bar penetration are uncommon and often cause serious damage without prompt treatment. Artifacts caused by the penetrating metal bar on computed tomography (CT) often obscure the actual brain damage along the path of penetration, and delayed treatment for the brain insult may result. We present 2 cases of transorbital brain injury following penetration...

Magnetic resonance imaging (MRI) near metallic implants remains an unmet need because of severe artifacts, which mainly stem from large metal-induced field inhomogeneities. This work addresses MRI near metallic implants with an innovative imaging technique called "Slice Encoding for Metal Artifact Correction" (SEMAC). The SEMAC technique corrects metal artifacts via robust encoding of each exci...

2-Hydroxy-4(-2,2,3,3,3-pentafluoropropoxy)-benzoic acid (UR-1505), a new molecule chemically related to salicylic acid, has immunomodulator properties and is currently under clinical development for treatment of atopic dermatitis. The present work describes the immunomodulatory profile of UR-1505. UR-1505 targets T cells, inhibiting their proliferation and cytokine production by blocking nuclea...

PURPOSE Our purpose was to define the role of dental bur fragments in producing metal artifacts on MR images. METHODS Dental prosthetic reconstructions were made for two dogs. The two lower second premolars were prepared for full-cast crowns by using a diamond bur. The crown margin was placed subgingivally on the right side (1 mm below the free gingival margin) and at the same level as the fr...

The potential large-scale applications of intermittent renewable energy sources require inexpensive, efficient, and less-resource-demanding storage systems to achieve grid balancing. Conventional unitized regenerative fuel cells (URFCs) based on the H2–H2O cycle are promising but suffer from high overpotential low efficiency. Here we demonstrate a highly efficient hydrogen peroxide cell (UR-HPC...

Utilization review (UR) has become a prominent approach to cost containment now used by almost 65% of private group insurance plans. Although insurers have increasingly relied on UR to contain health care costs, until recently little was known about the effects of this cost containment approach. This article reviews some of the key findings of a UR evaluation, based on analysis of claims data o...

This study aims to investigate the corrosion characteristics of bronze artifacts according lead contents by conducting a comprehensive analysis on layers and products focusing excavated ternary alloys with various chemical compositions.</br>From research outcome, selective corrosion, high-tin layers, compounds were identified in two artifacts, there was difference structure core metal bet...
