This study aimed to clarify the relationship of both facet tropism (FT) and the sagittally aligned facet (SAF) joint with lumbar disc herniation (LDH) and degenerative spondylolisthesis (DS). Overview of Literature: Despite several studies conducted, there is no consensus on the association of the SAF joint and FT with DH and DS. Methods: Between June 2015 and December 2017, magnetic resonance imaging scans of 250 consecutive patients who underwent surgery for LDH and DS were analyzed. The facet angles at all the lower lumbar levels were calculated, and SAF and FT were noted. The relationship between the side of di...

Authors: Srivastava A, Nanda G, Mahajan R, Nanda A, Batra S, Mishra N, Pandita N, Chhabra HS Abstract Study Design: Observational study of computed tomography (CT) data. Purpose: We performed a CT-based radiographic analysis of sub-axial cervical lamina in the Indian population to assess the feasibility of laminar screws. Overview of Literature: Morphometric studies have been performed for populations of various ethnic groups, but none exist for Indian populations. Methods: Cervical spine CT scans of 50 adults with a minimum slice thickness of

Publication date: Available online 17 October 2018Source: NeuroImageAuthor(s): Aoife M. Fitzpatrick, Neil M. Dundon, Kenneth F. ValyearAbstractThe current study investigates a new neurobiological model of human hand choice: The Posterior Parietal Interhemispheric Competition (PPIC) model. The model specifies that neural populations in bilateral posterior intraparietal and superior parietal cortex (pIP-SPC) encode actions in hand-specific terms, and compete for selection across and within hemispheres. Actions with both hands are encoded bilaterally, but the contralateral hand is overrepresented. We use a novel fMRI paradigm...

In this study, we constructed a new and sensitive ITO based electrochemical immunosensor for detection of interleukin 1β (IL-1β), a cancer biomarker found in serum and saliva. 6-phosphonohexanoic acid (PHA) was used as a biomolecule immobilization matrix for the first time. Anti-IL-1β antibody was utilized as a biorecognition molecule that immobilized onto carboxyl groups of 6-phosphohexanoic acid (PHA) via amide bond. Selective interaction between anti- IL-1β antibodies and IL-1β antigens was investigated by Electrochemical Impedance Spectroscopy (EIS), Cyclic Voltammetry (CV) and Single Frequency...

In-situ establishment of binary composites α-Fe2O3/Bi12O17Cl2 with both photocatalytic and photo-Fenton features. Chemosphere. 2018 Nov;210:257-266 Authors: Chang F, Wu F, Zheng J, Cheng W, Yan W, Deng B, Hu X Abstract A set of binary composites α-Fe2O3/Bi12O17Cl2 were established through an in-situ deposition route and these samples were systematically characterized by a collection of analytical techniques. Scanning electron microscopy, UV-vis diffuse reflectance spectroscopy, and X-ray photoelectron spectroscopy proved the coexistence of expected two components. High resolution transmiss...

Xin, Hongzheng Chen, Chao Gao, Hanying LiAbstractBiogenic single crystals have been widely demonstrated to incorporate macromolecules to achieve extra damage tolerance, spurring investigations on their synthetic analogs with enhanced mechanical properties as well as the enhancement mechanism(s) behind. And the investigations rely on both rational design of the single-crystal composites and, equally importantly, nanoscale and in-situ characterization strat...

Publication date: November 2018Source: Chinese Chemical Letters, Volume 29, Issue 11Author(s): Zhaozhong Li, Yang Li, Dong Wang, Qing Cui, Zhengqiang Li, Lei Wang, Huai YangAbstractA self-assembling bis-pyrene (BP) molecule with π-π interactions was designed and synthesized. In condensed state, the BP self-assembled into highly-ordered mesophase at room temperature, which was characterized by using differential scanning calorimetry (DSC), polarized optical microscope (POM), and 1D wide angle X-ray diffraction (WAXD) techniques. In solution, the BP self-assembled into nanofibers in the mixed dichloromethane and hexane...

Corrosion processes were evaluated for AISI 316 and AISI 1020 steels by scanning electron microscopy (SEM), atomic force microscopy (AFM) and light microscopy. Coupons were immersed in four crude oil samples with different total acid numbers (TANs) for 48 days at room temperature. The steels were also exposed to three blends (B1-B3), produced by quaternary mixtures of the oils, with lower TANs than their respective original oils. SEM micrographs showed pitting-type corrosion in most cases. AFM imaging showed drastic changes in the peak-to-peak values, topographic profiles and phase images of the AISI 1020 coupons exposed t...
