This data article contains complementary tables related to the research article entitled, 'Effects of repetitive transcranial magnetic stimulation on ER stress-related genes and glutamate, γ-aminobutyric acid, and glycine transporter genes in mouse brain' (Ikeda et al. (2017) [1]), which showed that rTMS modulates glutamate, GABA and glycine transporters and regulates ER stress-related genes. Here we provide accompanying data collected using Affymetrix GeneChip microarrays to identify changes in gene expression in mouse cerebrum treated with rTMS for 30 days (Tables 1-10)...

In this study, we determined the distribution of senecavirus A (SVA) and viral RNA load in different organs and tissues of naturally infected piglets. A TaqMan-based qRT-PCR assay was performed using RNA extracted from brainstem, cerebellum, cerebrum, heart, kidney, liver, lungs, small intestine, spleen, urinary bladder, and tonsils of seven newborn piglets. SVA was detected in 57 out of 70 tissue samples (81.4%). Viral loads ranged from 4.07 to 10.38 log10 genomic copies per g of tissue. The results show that SVA has tropism for various organs in naturally infected newborn piglets, especially for tonsils, spleen, lungs, and liver...

Cavernous Hemangiomas (CH) arise from any part of the cerebrum. Intraventricular lesions are rare and pure third ventricular localization is rare for CHs. Cavernomas of the ventricles may present with bleeding or signs associated with hydrocephalus. Radical excision is advocated for optimal management of cavernomas. In the present study, we present two cavernomas of the third ventricle which were completely excised via interhemispheric transcallosal transforaminal and Sylvian approaches. Radical excision should be the aim of the surgeon since reoperation for residual cavernomas is more commonly associated with complications and poor outcome...

Iron-Sulfur Cluster (ISC) biogenesis is a vital cellular process required to produce various ISC-containing proteins. These ISC proteins are responsible for essential functions such as glycine cleavage and the formation of lipoic acid, an essential cofactor of respiratory chain complexes. Defects in ISC biogenesis lead to multiple mitochondrial dysfunction syndromes including: ISCA2 with infantile onset leukodystrophy. Recently, a founder mutation, c.229G > A, p.Gly77Ser in ISCA2 was reported to cause Multiple Mitochondrial Dysfunction Syndrome type 4...

Disseminated tuberculomas in the brain and spinal cord are rare. To the best of our knowledge, only nine cases of spinal intra-medullary tuberculomas with cranial involvement have been reported till date. However, involvement of all levels in the spinal cord, brain stem with pan lobar involvement of the cerebrum and cerebellum has not been reported so far. We present such a case of a 12-year-old boy with history of pulmonary tuberculosis, who presented with gradual onset of quadriparesis and generalized seizures...

BACKGROUND: Multinodular and vacuolating neuronal tumor has been recently described and included in the World Health Organization Classification of Tumors of The Central Nervous System, even though its consideration as a true tumor is controversial. Patients with these lesions usually present with refractory seizures and inconclusive imaging findings that may be confused with other more common diagnoses such as dysembryoplastic neuroepithelial tumors or low-grade gliomas. Therefore, surgical resection is warranted to reach a pathologic diagnosis and seizure control...

MECP2 is the causative gene for autism spectrum disorders, including Rett syndrome, a regressive neurodevelopmental rare disease mainly occurring in girls. Except for the distinct methyl-CpG binding domain and the transcriptional repression domain in MeCP2, three AT-hook-like domains have recently been identified. Several mutations in AT-hook 1 domain have been reported in autism cases or Rett database. However, the role of AT-hook 1 domain is still unclear. In this study, we generated a mouse line carrying deletion of eight conserved amino acids in AT-hook 1 domain by clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 technology...

Post-mortem human neural tissues fixed in ethanol and aldehyde-based solutions express modulated frequency-dependent microvolt potentials when probed by chemical and electrical stimuli. These observations run contrary to the assumption that basic tissue functions are irreversibly impaired upon fixation, in the absence of nutrients and sufficient concentrations of physiological ions. The aim of the current study was to investigate the relative effects of pH and specific charged particles relevant to normal cell physiology upon electric potentials associated with fixed post-mortem rat brain tissue...

Glioblastoma (GBM) is an aggressive, grade IV brain tumor that develops from astrocytes located within the cerebrum, resulting in poor prognosis and survival rates following an accepted treatment regimen of surgery, radiation, and temozolomide. Thus, development of new therapeutics is necessary. During the last two decades, methylene blue (MB) has received increased attention as a potential neurotherapeutic due to its duality in brain cancers and neurodegenerative diseases. While MB is capable of easily permeating the blood-brain barrier, its therapeutic concentrations in GBM are known to induce off-target cytotoxicity and thus, another mode of drug delivery must be considered...

SBP2 (selenocysteine insertion sequence binding protein 2) is an essential factor in selenoprotein synthesis. Patients with SBP2 defects have a characteristic thyroid phenotype and additional manifestations such as growth delay, male infertility, impaired motor coordination and developmental delay. The thyroid phenotype has become pathognomonic for this defect and putative deficiencies in the iodothyronine deiodinases selenoenzymes have been implicated. To investigate the role of SBP2 and selenoproteins in thyroid physiology and answer questions raised by the human syndrome we generated a tamoxifen inducible Sbp2 conditional knockout (iCKO) mouse model...

Rhinocerebral mucormycosis is an acute, rapidly fatal, fungal infection, classically involving the nasal mucosa and paranasal sinuses. It is an aggressive, opportunistic infection that frequently progresses to involve the orbit and cerebrum. Cerebral extension in immunocompromised patients is almost universally fatal. There are limited data on mucormycosis in pediatric immunocompromised patients in the literature, with only few reports on rhinocerebral involvement. The immunocompromised patients described in this report presented with suspected periorbital and nasal cellulitis, progressing rapidly to necrotic changes in nasal tissue and oral palatal mucosa...

INTRODUCTION: To determine motor-related brain regions in which iron contents correlate with the degree of motor deficits of progressive supranuclear palsy (PSP). METHODS: Twenty-four patients with probable PSP and 20 controls were included. Using a 3.0T magnetic resonance imaging scanner, R2* values were measured in the putamen, globus pallidus (GP), substantia nigra (SN), subthalamic nucleus, and dentate nucleus. After adjustment for disease duration and age at examination, correlations between regional brain R2* values and Unified Parkinson Disease Rating Scale (UPDRS) total motor scores or subscores for bradykinesia, rigidity, tremor, or axial motor deficits were investigated...
