Alterations in dynamic brain network function are increasingly recognized in epilepsy. Benign childhood epilepsy with centrotemporal spikes (BECTS), or benign rolandic seizures, is the most common idiopathic focal epilepsy in children. In this study, we analyzed EEG functional connectivity (FC) among children with rolandic spikes with or without cl...

Significance: Transcranial photobiomodulation (tPBM) at 808 nm attenuates pentylenetetrazole (PTZ)-induced seizures and convulsive status epilepticus (CSE) in peripubertal rats by protecting neurons from injury and parvalbumin-positive interneurons from apoptosis, and preserving the integrity of perisomatic inhibitory networks. However, the effects...

Background Convulsive status epilepticus (CSE) prevention is critical for pediatric patients with epilepsy. Immediate intervention before CSE reduce severity. Despite its wide usage as an anticonvulsant, valproic acid (VPA) results in harmful side effects such as dose-dependent hepatotoxicity. Hence, reducing VPA dosage to minimize side effects whi...

Background: Atypical teratoid/rhabdoid tumor (AT/RT) is a rare, highly aggressive embryonal brain tumor most commonly presenting in young children. Methods: We performed a nationwide, population-based study of AT/RT (ICD-O-3 code: 9508/3) in Taiwan using the Taiwan Cancer Registry Database and the National Death Certificate Database. Results:...

Tibialis anterior (TA) muscle has frequently been used for scientific experiments, particularly for muscle contractile assays, because of its anatomical advantages. However, classical evaluation methods for the TA muscle, such as EMG and force transducer, require experimental skills to acquire reliable results. Furthermore, because sacrificing expe...

Objectives Whether febrile seizures (FS) produce long-term injury to the hippocampus or other brain structures is a critical question concerning focal onset seizures in children. Our aims are to evaluate the effect of FS on subfields of the hippocampus, thalamic nuclei, amygdala, cortical thickness, and surface area quantitatively in children with...

Sarcomas of bone, soft tissue, or neural origin may occasionally invade the central nervous system (CNS), causing diagnostic and therapeutic challenges. We aim to investigate the clinical features of sarcomas involving the CNS at initial presentation. During 2015/01–2019/12, nine consecutive patients (4 Males and 5 Females) younger than 30 years of...
Article
Despite remarkable advancements in modern medicine, muscular atrophy remains as an unsolved problem. It is well known that pathological characteristics of different atrophy types could vary according to the pathophysiological causes. In fact, the lesion of atrophy is not always homogenously distributed but often predominantly evident in either fast...

Background Epileptic surgery is the potentially curative treatment for children with refractory seizures. The study aimed to quantify and analyze high frequency oscillation (HFO) ripples and interictal epileptiform discharges (EDs) in intraoperative electrocorticography (ECoG) between malformation of cortical dysplasia (MCD) and non-MCD children wi...

Background: Ganoderma sp., such as Ganoderma tsugae (GT), play an important role in traditional Chinese medicine. Ganoderma sp. contains several constituents, including Sacacchin, which has recently drawn attention because it can not only enhance the repair of muscle damage but also strengthen the muscle enforcement. Although Ganoderma sp. have a...

Transcranial photobiomodulation (tPBM) with wavelength at 808 nm was applied to a rat model of acute seizures. The tPBM successfully attenuated convulsive status epilepticus, and the tPBM was shown to reduce the apoptosis of parvalbumin‐positive interneurons (PV‐INs) and preserved the integrity of perisomatic inhibitory network of PV‐INs to princip...

Convulsive status epilepticus is the most common neurological emergency in children. Transcranial photobiomodulation (tPBM) reverses elevated rodent neurotransmitters after status epilepticus (SE) yet whether tPBM can attenuate seizure behaviors remains unknown. Here, we applied near‐infrared laser at wavelength 808 nm transcranially to peripuberta...

The aim of this study was to evaluate the response of satellite cells to muscular atrophies which possess different pathological characteristics and which were induced by distinct damages. Right lower limbs of rats were exposed to denervation or disuse and later its tibialis anterior (TA) or soleus (SOL) muscles were analyzed. After confirming thei...

Spinal sarcopenia is a complex and multifactorial disorder associated with a loss of strength, increased frailty, and increased risks of fractures and falls. In addition, spinal sarcopenia has been associated with lumbar spine disorders and osteoporosis, which renders making decisions on treatment modalities difficult. Patients with spinal sarcopen...

Satellite cells, a population of skeletal muscular stem cells, are generally recognized as the main and, possibly, the sole source of postnatal muscle regeneration. Previous studies have revealed the potential of low-level laser (LLL) irradiation in promoting satellite cell proliferation, which, thereby, boosts the recovery of skeletal muscle from...

Background/purpose: To assess the long-term neurodevelopmental outcome of normal-term neonates who were accidentally found to exhibit subependymal pseudocysts (SEPCs), frontal horn cysts, or choroid plexus cysts through cranial ultrasound (CUS) examination in a neonatal health examination. Methods: In total, 5569 neonates received CUS examinatio...

Objectives: Brain tumors are found in 1-3% of children with newly onset of seizures. Understanding the impact of seizures on pediatric brain tumors and factors between seizures and brain tumors are crucial. This study aimed to evaluate the association of pediatric brain tumors on seizure occurrence and the relationships between seizures and the di...

Human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells are promising sources for the cell therapy of muscle diseases and can serve as powerful experimental tools for skeletal muscle research, provided an effective method to induce skeletal muscle cells is established. However, the current methods for myogenic differentiation from...

Our study is the first to demonstrate the ability to generate iPS cells from a mouse model of Pompe disease. Initially, mouse tail tip fibroblasts were harvested from male, 8-week-old (GAA) knockout mice, and three reprogramming factors (Oct3/4, Sox2 and Klf4) were transfected into the isolated donor cells using a retroviral vector. These iPS cells...

Recently multipotent stem cells have been established from neonatal mouse testis (Shinohara et al, Cell 2004). This multipotent germline stem cell (mGS) is very similar to embryonic stem cells. It differentiates into various types of somatic cells in vitro and produces teratomas after inoculation into mice. Here we show the characteristics of hemat...

Recent studies have indicated that bone marrow cells can regenerate damaged muscles and that they can adopt phenotypes of other cells by cell fusion. Our direct visualization system gave evidence of massive muscle regeneration by green fluorescent protein (GFP)-labeled CD45+c-Kit+Sca-1+Lin- cells (KSL cells), and we investigated the role of KSL cel...
