This work aimed to test and optimise reactive Planar Laser-Induced Fluorescence (PLIF) methods for the visualisation of micromixing regions in chemical reactors using standard PLIF Particle Image Velocimetry (PIV) equipment with laser source 512 nm. Two were tested: (i) an acid–base reaction fluorescein as reaction-sensitive tracer (ii) Fenton’s reaction, Rhodamine B tracer. Both test-reactions...

BACKGROUND The aim of study was to evaluate the effect of mechanical ventilation mode type, pressure-controlled ventilation (PCV), or volume-controlled ventilation (VCV) on intra- and postoperative surgical bleeding in patients undergoing posterior lumbar interbody fusion (PLIF) surgery. METHODS This was a prospective, randomized, single-blinded, and parallel study that included 56 patients u...

OBJECTIVE This study aimed to investigate radiographic fusion rates at L4-5 and L5-S1 after single level posterior lumbar interbody fusion (PLIF) and evaluate the relationship between fusion rates and preoperative disc slope angle (DSA), lumbar lordosis (LL), segmental angle (SA), and pelvic parameters. METHODS We conducted a retrospective review of patients who underwent single level PLIF at...

BACKGROUND Surgical interventions such as posterior lumbar interbody fusion (PLIF) with and without posterior instrumentation are often employed in patients with degenerative spinal conditions that fail to respond to conservative medical management. The VariLift® Interbody Fusion System was developed as a stand-alone solution to provide the benefits of an intervertebral fusion device without th...

STUDY DESIGN This is a retrospective study. PURPOSE To evaluate the advantages and effects of posterior lumbar interbody fusion (PLIF) using allograft and posterior instrumentation in the lumbar pyogenic discitis, which are resistant to antibiotics. OVERVIEW OF LITERATURE To present preliminary results of PLIF using a compressive bone graft with allograft and pedicle screw fixation in the l...

BACKGROUND Vitamin C has critical features relavant to postoperative pain management and functional improvement; however, no study has yet evaluated the effectiveness of vitamin C on improving the surgical outcomes for spine pathologies. Thus, this study aimed to explore the impact of vitamin C on postoperative outcomes after single-level posterior lumbar interbody fusion (PLIF) for lumbar spin...

OBJECTIVE Posterior accessed lumbar interbody fusion (PALIF) has a clear objective to restore disc height and spinal alignment but surgeons may occasionally face the converse situation and lose lumbar lordosis. We analyzed retrospective data for factors contributing to a postoperative flat back. METHODS A total of 105 patients who underwent PALIF for spondylolisthesis and stenosis were enroll...

Reactant mixing and combustion are investigated in an optically accessible, self-excited linear detonation combustor. The field is captured using 100 kHz planar laser-induced fluorescence (PLIF) imaging of acetone as a tracer the fuel supply, while chemiluminescence excited-state hydroxyl (OH*) radicals simultaneously resolves evolution wave. Time sequences acquired over multiple cycles each te...

The present review describes the current achievements in applications of a planar laser-induced fluorescence (PLIF) method for diagnostics liquid films, bubbles, individual droplets, and sprays. Such flows are related with strongly curved interphases, which often results additional high errors during PLIF data quantification because laser light reflection, refraction, absorption. demonstrates t...
