Neuroimaging features in a patient with non-ketotic hyperglycaemic seizures: A case report.

Background: Non-ketotic hyperglycaemic (NKH) seizures are a rare neurological complication of diabetes caused by hyperglycaemia in non-ketotic and non-hyperosmotic states. The clinical characteristics of NKH seizures are atypical and lack unified diagnostic criteria, leading to potential misdiagnoses in the early stages of the disease.

Case Summary: This report presents a rare case of NKH seizures in a 52-year-old male patient with a history of type 2 diabetes mellitus.

Targeted therapy improves cellular dysfunction, ataxia, and seizure susceptibility in a model of a progressive myoclonus epilepsy.

The recurrent variant KCNC1-p.Arg320His causes progressive myoclonus epilepsy (EPM) type 7, defined by progressive myoclonus, epilepsy, and ataxia, and is without effective treatment. KCNC1 encodes the voltage-gated potassium channel subunit Kv3.

Effects of salinity stress on methylation of the liver genome and complement gene in large yellow croaker (Larimichthys crocea).

Salinity is an important environmental factor that affects the yield and quality of large yellow croaker (Larimichthys crocea) during aquaculture. Here, whole-genome bisulfite sequencing (WGBS), RNA-seq, bisulfite sequencing PCR (BSP), quantitative real-time PCR (qPCR), and dual luciferase reporter gene detection technologies were used to analyze the DNA methylation characteristics and patterns of the liver genome, the expression and methylation levels of important immune genes in large yellow croaker in response to salinity stress. The results of WGBS showed that the cytosine methylation of CG type was dominant, CpGIsland and repeat regions were important regions where DNA methylation occurred, and the DNA methylation in upstream 2k (2000bp upstream of the promoter) and repeat regions had different changes in the liver tissue of large yellow croaker in the response to the 12‰, 24‰, 36‰ salinity stress of 4 w (weeks).

Corticohippocampal circuit dysfunction in a mouse model of Dravet syndrome.

Dravet syndrome (DS) is a neurodevelopmental disorder due to pathogenic variants in encoding the Nav1.1 sodium channel subunit, characterized by treatment-resistant epilepsy, temperature-sensitive seizures, developmental delay/intellectual disability with features of autism spectrum disorder, and increased risk of sudden death. Convergent data suggest hippocampal dentate gyrus (DG) pathology in DS () mice.

Mice with monoallelic loss exhibit reduced inhibitory synaptic input to cerebellar Purkinje cells.

encodes Gα, a heterotrimeric G protein α subunit in the G family. In this report, we used a mouse model "G203R" previously described as a "gain-of-function" mutant with movement abnormalities and enhanced seizure susceptibility. Here, we report an unexpected second mutation resulting in a loss-of-function Gα protein, and describe alterations in central synaptic transmission.

MiR-2014-5p and miR-1231-5p regulate muscle growth of Larimichthys crocea by targeting MSTN gene.

MicroRNAs (miRNAs) play an important role in regulating gene expression, and myostatin (MSTN) has been widely recognized as a key gene for muscle growth and development. Through high-throughput sequencing to study the effects of starvation on miRNA transcriptomes in Larimichthys crocea muscle tissue, we found that the expression of miR-2014, miR-1231 and miR-1470 were significantly different between fasting and normal feeding Larimichthys crocea. Bioinformatics analysis predicted that miR-2014, miR-1231 and miR-1470 target MSTN mRNA 3'UTR.

Circulating and tumor-infiltrating arginase 1-expressing cells in gastric adenocarcinoma patients were mainly immature and monocytic Myeloid-derived suppressor cells.

Myeloid-derived suppressor cells (MDSCs) are a group of heterogeneous cells derived from immature myeloid cells (IMCs). MDSCs are known to play important roles in tumor immune evasion. While we know that there are a large number of circulating and tumor-infiltrating MDSCs existing in gastric cancer (GC) patients, the phenotypic characteristics and arginase 1 (ARG1) expression levels of these MDSCs remain very unclear.

Mice with R209H Movement Disorder Variant Display Hyperlocomotion Alleviated by Risperidone.

Neurodevelopmental disorder with involuntary movements (Online Mendelian Inheritance in Man: 617493) is a severe, early onset neurologic condition characterized by a delay in psychomotor development, hypotonia, and hyperkinetic involuntary movements. Heterozygous de novo mutations in the gene cause neurodevelopmental disorder with involuntary movements. G the gene product of , is the alpha subunit of G, a member of the heterotrimeric G family of G proteins.

Exosomal miRNA-107 induces myeloid-derived suppressor cell expansion in gastric cancer.

  Myeloid-derived suppressor cells (MDSCs) promote immunosuppression in the tumor microenvironment, support tumor growth and survival, and may contribute to immunotherapy resistance. Recent studies showed that tumor-derived exosomes (TDEs) can induce MDSCs accumulation and expansion, the mechanisms of which are largely unknown. The morphologies and sizes of the exosomes was observed by using a JEM-1400 transmission electron microscope.

Mouse models of GNAO1-associated movement disorder: Allele- and sex-specific differences in phenotypes.

Background: Infants and children with dominant de novo mutations in GNAO1 exhibit movement disorders, epilepsy, or both. Children with loss-of-function (LOF) mutations exhibit Epileptiform Encephalopathy 17 (EIEE17). Gain-of-function (GOF) mutations or those with normal function are found in patients with Neurodevelopmental Disorder with Involuntary Movements (NEDIM).

A mechanistic review on GNAO1-associated movement disorder.

Mutations in the GNAO1 gene cause a complex constellation of neurological disorders including epilepsy, developmental delay, and movement disorders. GNAO1 encodes Gα, the α subunit of G, a member of the G family of heterotrimeric G protein signal transducers. G is the most abundant membrane protein in the mammalian central nervous system and plays major roles in synaptic neurotransmission and neurodevelopment.
