The use of environmental DNA (eDNA) methods for community analysis has recently been developed. High-throughput parallel sequencing (HTS), called eDNA metabarcoding, increasingly used in studies to examine multiple species. However, metabarcoding methodology requires validation based on traditional all natural ecosystems before a reliable method can be established. To date, relatively few have performed fishes aquatic environments where fish communities were intensively surveyed using...
Importance Loneliness is suggested to negatively affect physical and mental health influence the development of disability; however, a consensus on relationship between loneliness disability has not been reached. Age-related hearing impairment worsens daily-life activities older adults, association incidence may be influenced by impairment. Objective To examine among adults stratified Design, Setting, Participants This prospective observational cohort study included 5563 community-dwelling...
Regular physical activity throughout life is generally recommended to prevent dementia; however, there little evidence regarding the association between lifetime and mild cognitive impairment (MCI), which often precedes dementia. This study aimed examine of their transitions with late-life MCI.
Introduction: Maximizing the benefits of physical activity (PA) is important to prevent frailty for a measure this public health issue. This study aimed investigate association timing PA with conversion frailty. Methods: longitudinal observational enrolled total 1,310 community-dwelling Japanese older adults who in National Center Geriatric and Gerontology－Study Syndromes remained as examined population. A checkup was conducted baseline characteristics. Subsequently, objectively measured...
Background : We aimed to develop and validate a multivariable model for predicting dropout from community-based going-out program older adults. Methods The National Center Geriatric Gerontology’s Study of Syndromes, with prospective cohort general adults, was employed. A total 5905 adults who were independent in their activities daily living recruited randomly allocated into training, validation, testing data sets 6:2:2 ratio. An outcome defined as dropping out within 180 days. extreme...
OBJECTIVE Microvascular decompression (MVD) is effective for the treatment of trigeminal neuralgia (TN), hemifacial spasm (HFS), and glossopharyngeal neuralgia. The transposition technique standard procedure to avoid adhesions granuloma around site but more complex difficult perform than interposition technique. authors describe a simple safe MVD they call "birdlime" technique, which uses tissue glue-coated collagen sponge soaked with fibrin glue, results this METHODS retrospectively...
Abstract Films that can form bioadhesive hydrogels on wet biotissues absorbing blood or body fluids are useful for medical devices such as hemostats, adhesion barriers, wound dressings, and drug release devices. We focused a hydrogen‐bonding polymer complex consisting of poly(acrylic acid) (PAA) poly(vinylpyrrolidone) (PVP). PAA is known tissue‐adhesive polymer. However, simple mixing aqueous PVP solutions resulted in the formation an insoluble nonadhesive precipitate. developed novel...
Abstract Phylogeography bears an important part in ecology and evolution. However, current phylogeographic studies are largely constrained by limited numbers of individual samples. Using environmental DNA (eDNA) assay for analyses, this study provides detailed information regarding the history Siberian stone loach Barbatula toni , a primary freshwater fish across whole range Hokkaido, Japan. Based on eDNA metabarcoding 293 river water samples, we detected from B. 189 rivers. A total 51...
The quantum mechanics on the hypersurface VN-1 embedded in Euclidean space RN is examined. quantization done accordance with Dirac method, and as a result some additional term proportional to ħ2 appears potential energy. This has information of exterior hypersurface; thus, Riemann without any kind world different from space.
The head-up display (HUD) is a modern technology that projects images or numeric information directly into the observer's sight line. Surgeons will no longer need to look away from surgical view using HUD system confirm preoperative navigation image. present study investigated usefulness of for performing cerebral aneurysm clipping surgeries.Thirty-five patients underwent surgery, including 20 keyhole surgeries unruptured aneurysm, system. Image structures such as skull, vasculature, and was...
The failures of recent studies intended to prevent cerebral vasospasm have moved the focus research into delayed ischemia away from artery constriction towards other mechanisms. Recent accumulating evidence has suggested that early brain injury is also involved in development ischemia, and hydrogen can injury. Therefore, we established a combination therapy intravenous infusion intra-cisternal magnesium sulfate for treatment both vasospasm. present randomized controlled clinical trial...
OBJECTIVE Advanced age is known to be associated with a poor prognosis after surgical clipping of unruptured intracranial aneurysms (UIAs). Keyhole techniques have been introduced for less invasive treatment UIAs. In this study, the authors compared complications and clinical radiological outcomes keyhole between nonfrail elderly patients (≥ 70 years) nonelderly patients. METHODS (either supraorbital or pterional) was performed treat 260 cases relatively small (≤ 10 mm) anterior circulation...
We have previously argued about the quantum mechanics on hypersurface VN-1 embedded in Euclidean space RN. generalize formalism to case of VL RN with 1 ≦L ≪ N. The result is essentially same as previous one and additional term proportional \hbar2 appears potential energy which related extrinsic mean curvature
Abstract BACKGROUND: The extradural temporopolar transcavernous approach can be used to treat central skull base pathologies, but control of bleeding from the opened cavernous sinus is essential. Oxidized cellulose cotton packing and fibrin glue injection used, effect on postoperative venous draining pattern remains unclear. OBJECTIVE: To investigate changes in drainage immediately after surgery with without into sinus. METHODS: A total 82 patients treated via were retrospectively divided 2...
Extradural temporopolar approach (ETA) has been modified as less invasive manner and named trans-superior orbital fissure (SOF) with mini-peeling technique. The present study discusses the operative nuances of this technique on basis cadaveric lateral cavernous structures.In five consecutive specimens, we performed an extradural anterior clinoidectomy dura propria to expose clinoid process entirely. We also investigated histological characteristics sinus (CS) between periosteal at SOF,...
We consider the quantum mechanics of SU(2) skyrmion model in framework collective-coordinate quantization. treat Lagrangean quantum-mechanically from beginning. A new mass term with negative sign appears, which may play an important role stabilizing rotating chiral soliton.
Objective: When the bone flap is removed in a pterional craniotomy, middle meningeal artery (MMA) should be gently dissected to minimize blood loss. However, when MMA pierces bony tunnel groove it easily damaged upon elevation. We have performed an anatomic study of this render craniotomy safer.
Delayed brain injury (DBI) is considered one of the most important causes mortality and morbidity after subarachnoid hemorrhage (SAH). However, no suitable experimental rat endovascular perforation (EVP) SAH model was available for investigating DBI. The authors added early cerebral hypoperfusion to a mild EVP by unilateral common carotid artery occlusion (UCCAO) 24 hours induction mimic clinical course SAH.
Early preventive measures against depression have become important with unprecedented global aging. Increase in one's perceived value (PV) may correspond to better mental health outcomes. This cross-sectional observation study aimed clarify whether the PV of adopting new behaviors is associated depressive symptoms. The participants were 5266 community-dwelling older adults aged ≥ 65 years. We developed a questionnaire measure behaviors, specifically activities beneficial for preventing...
