Initial Efficacy after Lateral Lumbar Interbody Fusion in Degenerative Lumbar Spinal Stenosis Classified as Schizas Grade A to D.

Objective: This study was to evaluate the initial efficacy of lateral lumbar interbody fusion (LLIF) in treating degenerative lumbar spinal stenosis (DLSS), encompassing a spectrum of stenosis severity from minor to extreme cases.

Methods: This retrospective study analyzed the outcomes of 43 patients with DLSS, involving 55 surgical segments, who underwent LLIF. Clinical efficacy and radiographic parameters were recorded during the perioperative period and at the final follow-up.

Coupling effect between the structure and surface characteristics of electrospun carbon nanofibres on the electrochemical activity towards the VO2(+)/VO(2+) redox couple.

In order to investigate the structure-function relationship of electrospun carbon nanofibres (ECNFs), polyacrylonitrile (PAN)-based electrospun carbon webs (ECWs) have been developed, consisting of ECNFs carbonized over the temperature range of 1000-1500 °C in a nitrogen atmosphere. The surface morphology, microstructure, composition, electrical conductivity and hydrophilicity of the ECNFs have been characterized. The electrochemical activity of the ECNFs towards the VO2(+)/VO(2+) redox reaction has been measured by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS).
