Therapeutic Application of High-Frequency rTMS Combined with Intensive Occupational Therapy for Pediatric Stroke Patients with Upper Limb Hemiparesis: A Case Series Study

Journal of Behavioral and Brain Science 2013年第2期3卷 188-193页

Low-frequency repetitive transcranial magnetic stimulation (LF-rTMS) applied to the non-lesional hemisphere is reported to significantly improve motor function of the affected upper limb in adult stroke patients with hemiparesis. For pediatric stroke patients, the beneficial effects of LF-rTMS have been already confirmed in a randomized controlled study. However, there is no report of therapeutic application of high-frequency rTMS (HF-rTMS) in this patient population. In this case series study, we introduced HF-rTMS combined with intensive occupational therapy (OT) in two pediatric hemiparetic patients. We studied two children (8- and 9-year-old boys, both right-handed) with post-stroke upper limb hemiparesis (chronic phase). Both patients underwent 22 treatment sessions of HF-rTMS/OT during 15-day hospitalization. The HF-rTMS was applied over the lesional motor cortex at a frequency of 10Hz for 15 minutes in each session. One session of intensive OT consisted of 30-min one-to-one training and 30-min self-exercise. Motor function of the affected upper limb was serially evaluated with Fugl-Meyer Assessment (FMA), Wolf Motor Function Test (WMFT), Simple Test for Evaluating hand Function (STEF), and Ten-second Test. Neither of the patients showed any adverse effects. Both patients showed improvement of motor function in the affected upper limb and were able to use the affected upper limb in some activities of daily living. In the two post-stroke pediatric patients, HF-rTMS/OT was safe and improved upper limb muscle function. Confirmation of these effects in a larger population is needed.

Operationally Simple Enantioselective Silane Reduction of Ketones by the [Ir(OMe)(cod)]₂/Azolium Catalytic System

引用

International Journal of Organic Chemistry 2024年第1期14卷 1-19页

作者： Satoshi Sakaguchi Chika Nagao ryo Ichihara Shogo Matsuo Department of Chemistry and Materials Engineering Faculty of Chemistry Materials and Bioengineering Kansai University Suita Japan

An operationally simple protocol was designed for the enantioselective silane reduction (ESR) of ketones using air- and moisture-stable [Ir(OMe)(cod)]2 (cod = 1,5-cyclooctadiene) (3) as a metal catalyst precursor. This reaction was driven by chiral hydroxyamide-functionalized azolium salt 2. The catalytic ESR reaction could be performed under benchtop conditions at room temperature. Treatment of 2 with 3 in THF yielded the monodentate IrCl(NHC)(cod) (NHC = N-heterocyclic carbene) complex 4 in 93% yield, herein the anionic methoxy ligand of 3 serves as an internal base that deprotonates the azolium ring of 2. The well-defined Ir complex 4 catalyzed the ESR reaction of propiophenone (6) with (EtO)2MeSiH using the pre-mixing reaction procedure. Based on this success, the catalytic ESR reaction was designed and implemented using an in situ-generated NHC/Ir catalyst derived from 2 and 3. Thus, a wide variety of aryl ketones could be reduced to the corresponding optically active alcohols in moderate to excellent stereoselectivities at room temperature without temperature control. Since the high catalytic activity of 3 was observed, we next evaluated several other transition metal catalyst precursors for the catalytic ESR reaction under the influence of 2. This evaluation revealed that Ir(acac)(cod) (acac = acetylacetonate) (28) and [IrCl(cod)]2 (5) can be successfully used as metal catalyst precursors in the ESR reaction.

Stresses in the Scapular Fossa Do Not Exceed the Yield Stress When Elevated up to 135 Degrees of Abduction after Reverse Shoulder Arthroplasty

引用

Journal of Biomedical Science and Engineering 2024年第2期17卷 35-40页

作者： Rina Sakai Tomonori Kenmoku ryo Tazawa Kazuhiro Yoshida Tomomi Mizuhashi Masanobu Ujihira Department of Medical Engineering and Technology Kitasato University School of Allied Health Sciences Sagamihara Japan Department of Orthopedic Surgery Kitasato University School of Medicine Sagamihara Japan Kitasato University Graduate School of Medical Sciences Sagamihara Japan

Reverse shoulder arthroplasty (RSA) is an effective treatment for rotator cuff tears. Despite its advantages, complications occur at a high rate. Complications requiring revision include a high rate of base plate failure, 38% of which are due to instability. The primary stability the base plate ensures is a crucial factor and, thus, is the subject of much debate in clinical studies and biomechanical research. This study is aimed to provide data that will contribute to the base plate’s pri-mary stability and glenoid longevity by clarifying the stresses at the scapular fossa and base plate interface associated with elevation after RSA. A 3D finite element model was created from the DICOM data for the scapulohumeral joint and SMR shoulder system. For loading conditions, 30 N was applied for each posi-tion with abduction angles of 0, 45, 90, and 135 degrees. A three-dimensional fi-nite element analysis was performed using the static implicit method with LS-DYNA. The von Mises stresses in the scapular fossa were found not to exceed the yield stress on the bone even after elevation to an abduction angle of 135 de-grees after RSA. It is rough to uniformly compare the yield stress and the von Mises stress, but it was inferred that the possibility of fracture is low unless a large external force is applied. A maximum von Mises stress showed 0 degrees of abduction, suggesting that the lowered position is in a more severe condition than the elevated position. If better improvement is desired, it may be necessary to devise ways to reduce the stress on the upper screw. .
