Oxidation of bisphenol A (BPA) and related compounds by the multifunctional catalytic globin dehaloperoxidase.

Dehaloperoxidase (DHP) from the marine polychaete Amphitrite ornata is a multifunctional enzyme that possesses peroxidase, peroxygenase, oxidase and oxygenase activities. Herein, we investigated the reactivity of DHP B with bisphenol A (BPA) and related compounds (bisphenol E, bisphenol F, tetrachlorobisphenol A, 2,2'-biphenol, 3,3'-biphenol, 4,4'-biphenol, and 3,3'-dibromo-4,4'-biphenol). As a previously unknown substrate for DHP B, BPA (as a representative substrate) is an endocrine disruptor widely used in polycarbonate and epoxy resins, thus resulting in human exposure.

Usefulness of Source Images of Magnetic Resonance Myelograms and Partial Laminectomy for Interlaminar Endoscopic Lumbar Discectomy at L5-S1: A Technical Note and Preliminary Clinical Results.

Abstract: The primary objective of this study was to assess the clinical and radiologic outcomes and introduce the technical notes from 10 patients who underwent interlaminar endoscopic lumbar discectomy (IELD) at L5-S1 using the source images of magnetic resonance (MR) myelograms and performing partial laminectomy. A biportal endoscopic system was used to perform partial laminectomy, followed by fragmentectomy and subtotal discectomy using a uniportal endoscopic system. The source images of MR myelograms were used to identify the anatomical relationship between the herniated disc material, L5 and S1 nerve roots, the thecal sac, and L5 lamina.

Continuous wound infiltration of ropivacaine for reducing of postoperative pain after anterior lumbar fusion surgery: a clinical retrospective comparative study.

Background: Local anesthetic infiltration at the site of a surgical wound is commonly used to control postoperative pain. In this study, we examined the effectiveness of continuous local infiltration at an abdominal surgical site in patients undergoing anterior lumbar interbody fusion (ALIF) surgery.

Methods: Sixty-one patients who underwent ALIF surgery were enrolled.

Open Lumbar Microdiscectomy and Posterolateral Endoscopic Lumbar Discectomy for Antero- and Retrospondylolisthesis.

Background: Posterolateral endoscopic lumbar discectomy (PLELD) or percutaneous endoscopic lumbar discectomy has been reported to be effective as treatment for herniated lumbar disc in degenerative spondylolisthesis. Few studies have investigated the outcomes of open lumbar microdiscectomy (OLM) and PLELD for antero- and retrospondylolisthesis with mild slippage and instability.

Objectives: We aimed to evaluate the outcomes of OLM and PLELD for antero- and retrospondylolisthesis with mild slippage and instability.

Developing a new chemosensor targeting zinc ion based on two types of quinoline platform.

A chemosensor DQ (2-(2-(quinolin-2-yl)hydrazinyl)-N-(quinolin-8-yl)acetamide), based on two quinoline moieties, has been synthesized. DQ could detect zinc ion through fluorescence turn-on in aqueous media. Limit of detection was calculated as 0.

Highly Sensitive Dansyl-Based Chemosensor for Detection of Cu in Aqueous Solution and Zebrafish.

A new dansyl-based chemosensor (2-(4-((5-(dimethylamino)naphthalen-1-yl)sulfonyl)piperazin-1-yl)--(quinolin-8-yl)acetamide) ( for detecting Cu was synthesized and characterized. showed great selectivity to Cu by a fluorescent "on-off" detection method. Job plot, ESI-mass spectroscopy, and H NMR titration suggested a 1 to 1 binding mode between and Cu.

Fluorescent determination of zinc by a quinoline-based chemosensor in aqueous media and zebrafish.

A quinoline-based fluorescence sensor QDTD was developed for Zn. QDTD can detect Zn by fluorescence turn-on. Detecting limit (0.

An Imidazo[1,5-α]Pyridine-Based Fluorometric Chemodosimeter for the Highly Selective Detection of Hypochlorite in Aqueous Media.

A new fluorometric chemodosimeter 2-amino-3-(((E)-3-(1-phenylimidazo[1,5-α]pyridin-3-yl)benzylidene)amino)maleonitrile (BPI-MAL) has been designed and synthesized for sensing hypochlorite. BPI-MAL showed a selective turn-on fluorescence for ClO through hypochlorite-promoted de-diaminomaleonitrile reaction. It also could detect ClO in the presence of various competitive anions including reactive oxygen species.

A multifunctional selective "turn-on" fluorescent chemosensor for detection of Group IIIA ions Al, Ga and In.

A versatile chemosensor 1 (E)-2-(((8-hydroxy-2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij]quinolin-9-yl)methylene)amino)-1H-benzo[de]isoquinoline-1,3(2H)-dione, based on naphthalimide and julolidine moieties, was developed for highly distinguishable and selective recognition of Group IIIA metal ions (Al3+, Ga3+ and In3+). Sensor 1 exhibited significant 'off-on' fluorescence responses at 488 nm in the presence of Al3+ and at 570 nm in the presence of Ga3+ and In3+. The same emission of Ga3+ and In3+ could be distinguished through different color changes (from colorless to yellow for Ga3+ and no color change for In3+).

A Multi-Responsive Naphthalimide-Based "Turn-on" Fluorescent Chemosensor for Sensitive Detection of Trivalent Cations Ga, Al and Cr.

A new multifunctional chemosensor 1, (E)-2-(((2-hydroxynaphthalen-1-yl)methylene)amino)-1H-benzo[de]isoquinoline-1,3(2H)-dione, based on naphtalimide and naphthaldehyde was developed, which showed the fluorescence responses to trivalent metal ions (Ga, Al and Cr). Sensor 1 detected and differentiated selectively trivalent metal ions Ga, Al and Cr by fluorescence enhancement at different emissions. The association constant of Ga-2∙1 complex is the highest one among those of the organic chemosensors reported, to date.

Salvage Anterior Lumbar Interbody Fusion for Pseudoarthrosis After Posterior or Transforaminal Lumbar Interbody Fusion: A Review of 10 Patients.

Background: After interbody cage implantation for posterior or transforaminal lumbar interbody fusion (PLIF or TLIF) spinal fusion surgery, pseudoarthrosis can develop. However, there are several shortcomings of the posterior approach if the interbody cage requires removal. Therefore, an anterior approach may be useful.

Use of a Zero-Profile Device for Contiguous 2-Level Anterior Cervical Diskectomy and Fusion: Comparison with Cage with Plate Construct.

Background: A new zero-profile, standalone device (Zero P) was recently developed and has shown a lower incidence rate of complications and competitive clinical outcomes compared with anterior cervical cage with plate construct (CP) in single and multilevel anterior cervical diskectomy and fusion (ACDF). However, there is still concern whether Zero P is appropriate for multilevel ACDF. In addition, there have been few reports of contiguous 2-level ACDF used in conjunction with Zero P.

Salvage Percutaneous Vertebral Augmentation Using Polymethyl Methacrylate in Patients with Failed Interbody Fusion.

Background: Percutaneous vertebral augmentation with cement is used as a salvage procedure for failed instrumentation. Few studies have reported the use of this procedure for failed anterior lumbar fusion in elderly patients with osteoporosis and other complicated diseases who have undergone a previous major operation.

Methods: Between January 2007 and December 2015, the clinical and radiographic results of 8 patients with osteoporosis who showed subsidence and migration of the implant after an initial operation were examined.

An Upper and Middle Cervical Spine Posterior Arch Defect Leading to Myelopathy and a Thoracic Spine Posterior Arch Defect.

Background: Abnormalities of the posterior arches of the upper and middle cervical spine that can cause myelopathy are rare, and no reports of such defects at the thoracic spinal level have been published.

Case Description: A 29-year-old male patient reported right arm weakness and pain for 1 year. Magnetic resonance imaging of the cervical spine showed spinal canal stenosis at the C3-4 and C4-5 levels, as well as a posterior arch defect at the C2, 3, and 4 levels that was compressing the spinal cord.
