Chronic hepatitis and fatty liver, recognized precursors, underscore the imperative need for effective preventive strategies. This study explores colchicine, traditionally acknowledged for its anti-inflammatory properties and investigates its potential in liver cancer prevention.

Rosai-Dorfman disease mimicking craniopharyngioma: a challenging differential diagnosis. Illustrative case.

Background: Rosai-Dorfman disease (RDD) is a rare non-Langerhans histiocytic disorder with less than 5% central nervous system involvement and is often mistaken for meningioma given the similarity in imaging features. The authors present the unique case of a 44-year-old female who presented with ongoing visual impairment.

Observations: A purely suprasellar mass was noted on magnetic resonance imaging and was initially diagnosed as craniopharyngioma.

Images Combined With Surgical Procedures and Pathological Identification to Distinguish a Reactive Histiocytosis With Organized Hematoma From a Malignant Peripheral Nerve Sheath Tumor.

Background/aim: Malignant peripheral nerve sheath tumors (MPNST) are rare soft tissue malignant tumors. To the best of our knowledge, there have been no previous reports of benign reactive histiocytosis with hematoma that mimics MPNST on medical images.

Case Report: A 57-year-old female with past history of hypertension came to our clinic due to low back pain with radiculopathy which was diagnosed with a tumor arising from L2 neuroforamen with L2 pedical erosion.

Case report of intracranial large vessel occlusion in glioblastoma multiforme patient after radiation therapy.

Introduction: Vasculopathy of the large arteries is a prominent complication of radiotherapy. Radiation-induced cerebral vasculopathy can cause arterial stenosis/occlusion, cerebral hemorrhage, and aneurysm formation. We report a cases of glioblastoma multiforme (GBM) with occlusive radiation vasculopathy (ORV).

Universal scaling of extinction time in stochastic evolutionary dynamics.

Evolutionary dynamics is well captured by the replicator equations when the population is infinite and well-mixed. However, the extinction dynamics is modified with finite and structured populations. Experiments on the non-transitive ecosystem containing three populations of bacteria found that the ecological stability sensitively depends on the spatial structure of the populations.

Patient-derived tumor organoids as a platform of precision treatment for malignant brain tumors.

Malignant brain tumors consist of malignancies originated primarily within the brain and the metastatic lesions disseminated from other organs. In spite of intensive studies, malignant brain tumors remain to be a medical challenge. Patient-derived organoid (PDO) can recapitulate the biological features of the primary tumor it was derived from and has emerged as a promising drug-screening model for precision therapy.

Elevation of hilar mossy cell activity suppresses hippocampal excitability and avoidance behavior.

Modulation of hippocampal dentate gyrus (DG) excitability regulates anxiety. In the DG, glutamatergic mossy cells (MCs) receive the excitatory drive from principal granule cells (GCs) and mediate the feedback excitation and inhibition of GCs. However, the circuit mechanism by which MCs regulate anxiety-related information routing through hippocampal circuits remains unclear.

Recombinant Baculovirus: A Flexible Drug Screening Platform for Chikungunya Virus.

Chikungunya virus (CHIKV) is a mosquito-transmitted infectious agent that causes an endemic or epidemic outbreak(s) of Chikungunya fever that is reported in almost all countries. This virus is an intense global threat, due to its high rate of contagion and the lack of effective remedies. In this study, we developed two baculovirus expression vector system (BEVS)-based approaches for the screening of anti-CHIKV drugs in insect (Sf21) cells and U-2OS cells.

Use of a Smartphone Application to Speed Up Interhospital Transfer of Acute Ischemic Stroke Patients for Thrombectomy.

In most countries, large cerebral artery occlusion is identified as the leading cause of disability. In 2015, five large-scale clinical trials confirmed the benefit of intra-arterial thrombectomy. However, thrombectomy is a highly technical and facility-dependent procedure.

Anticipation and negative group delay in a retina.

The mechanism of negative group delay (NGD) is used to understand the anticipatory capability of a retina. Experiments with retinas from bullfrogs are performed to compare with the predictions of the NGD model. In particular, whole field stochastic stimulations with various autocorrelation times are used to probe anticipatory responses from the retina.

Analysis of Environmental and Typhoon Effects on Modal Frequencies of a Power Transmission Tower.

The structural health monitoring of power transmission towers (PTTs) has drawn increasing attention from researchers in recent years; however, no long-term monitoring of the dynamic parameters of PTTs has previously been reported in the literature. This study performed the long-term monitoring of an instrumented PTT. An automated subspace identification technique was used to extract the dynamic parameters of the PTT from ambient vibration measurements taken over approximately ten months in 2017.

Long-Term Follow-up in Patients with Spontaneous Intracerebral Hemorrhage Treated With or Without Surgical Intervention: a Large-Scale Retrospective Study.

Debates regarding the most beneficial medical or surgical procedures for patients with spontaneous intracerebral hemorrhage (sICH) are still ongoing. We aimed to evaluate the risk of subsequent vascular disease and mortality in patients with sICH treated with and without surgical intervention, in a large-scale Asian population. Patients hospitalized within 2000 to 2013 who were newly diagnosed with sICH were identified using the National Health Insurance Research Database of Taiwan.

Patient Transfer Decision Difficulty Scale: Development and psychometric testing of emergency department visits by long-term care residents.

Background And Objectives: Nurses serve as gatekeepers of the health of long-term care facility (LTCF) residents and are key members deciding whether residents should visit an emergency department (ED). Inappropriate decisions as to ED visits may result in ED overcrowding, excessive medical expenses, and nosocomial infections. Currently, there is a lack of effective tools for assessing the barriers and level of difficulty experienced by LTCF nurses.

Risk of subsequent stroke, with or without extracranial-intracranial bypass surgery: a nationwide, retrospective, population-based study.

Objective: Although no benefits of extracranial-intracranial (EC-IC) bypass surgery in preventing secondary stroke have been identified previously, the outcomes of initial symptomatic ischemic stroke and stenosis and/or occlusion among the Asian population in patients with or without bypass intervention have yet to be discussed. The authors aimed to evaluate the subsequent risk of secondary vascular disease and cardiac events in patients with and without a history of this intervention.

Methods: This retrospective nationwide population-based Taiwanese registry study included 205,991 patients with initial symptomatic ischemic stroke and stenosis and/or occlusion, with imaging data obtained between 2001 and 2010.

Inhibition of astrocytic activity alleviates sequela in acute stages of intracerebral hemorrhage.

Neurological deterioration of intracerebral hemorrhage (ICH) mostly occurs within the first 24 hours. Together with the microglia/macrophages (MMΦ), astrocytes are important cell population responsible for many brain injuries but rarely being highlighted in acute stage of ICH. In present study, we induced rats ICH either by collagenase or autologous blood injection.

Positive feedback and synchronized bursts in neuronal cultures.

Synchronized bursts (SBs) with complex structures are common in neuronal cultures. Although the phenomenon of SBs has been discovered for a long time, its origin is still unclear. Here, we investigate the properties of these SBs in cultures grown on a multi-electrode array.

Characterization of Predictive Behavior of a Retina by Mutual Information.

Probing a bullfrog retina with spatially uniform light pulses of correlated stochastic intervals, we calculate the mutual information between the spiking output at the ganglion cells measured with multi-electrode array (MEA) and the interval of the stimulus at a time shift later. The time-integrated information from the output about the future stimulus is maximized when the mean interval of the stimulus is within the dynamic range of the well-established anticipative phenomena of omitted-stimulus responses for the retina. The peak position of the mutual information as a function of the time shift is typically negative considering the processing delay of the retina.

Head-to-head comparisons of bisphosphonates and teriparatide in osteoporosis: a meta-analysis.

Purpose: This meta-analysis aimed to compare the efficacy and safety of teriparatide vs. bisphosphonates in the management of osteoporosis.

Methods: A total of 1,967 patients from eight randomized controlled trials were analyzed; outcomes included bone mineral density (BMD) of the femoral neck, total hip and lumbar spine, vertebral and nonvertebral fractures and any adverse event.

Clinical Evaluation of Acupuncture as Treatment for Complications of Cerebrovascular Accidents: A Randomized, Sham-Controlled, Subject- and Assessor-Blind Trial.

. The effect of acupuncture as treatment for poststroke complications is questionable. We performed a randomized, sham-controlled double-blind study to investigate it.

PG2 for patients with acute spontaneous intracerebral hemorrhage: a double-blind, randomized, placebo-controlled study.

PG2 is an infusible polysaccharide extracted from Astragalus membranaceus, which is a Chinese herb traditionally used for stroke treatment. We investigated the effect of PG2 on patients with spontaneous acute intracerebral hemorrhage (ICH). A total of 61 patients with acute spontaneous ICH were randomized to either the treatment group (TG, 30 patients), which received 3 doses of PG2 (500 mg, IV) per week for 2 weeks, or the control group (CG, 31 patients), which received PG2 placebo.

Local hemostatic matrix for endoscope-assisted removal of intracerebral hemorrhage is safe and effective.

Background/purpose: Minimally invasive endoscope-assisted (MIE) evacuation of spontaneous intracerebral hemorrhage (ICH) is simple and effective, but the limited working space may hinder meticulous hemostasis and might lead to rebleeding. Management of intraoperative hemorrhage is therefore a critical issue of this study. This study presents experience in the treatment of patients with various types of ICH by MIE evacuation followed by direct local injection of FloSeal Hemostatic Matrix (Baxter Healthcare Corp, Fremont, CA, USA) for hemostasis.
