Терапевтический потенциал Пранлукаста против провокационного демиэлирования и сенсорного расстройства в мышах: Сопоставление с фенолимодом.

Воспламенительное обезвоживание присутствует в таких изнурительных болезнях, как множественный склероз (MS). В Соединенных Штатах имеется несколько лекарств для лечения люминесцентных заболеваний, при этом финголимод является пероральным опционом первой линии. Однако пока еще не найдено лекарство, и широко распространены случаи неудач в лечении, что свидетельствует о необходимости продолжения исследований по новым фармакологическим целям. Пранлукаст продемонстрировал позитивное воздействие на миелинизацию в клеточной культуре и после демиэлизации в мышах, вызванной ЛПК, но она еще не является

EP was associated with increased QA in the body and tapetum of corpus callosum (CC) and decreased QA in the bilateral cerebellum, and middle cerebellar peduncle. Compared to non-affective psychosis, affective psychosis showed increased QA in the bilateral cerebellum and vermis and decreased QA in the forceps minor, body of CC, …

Early region-specific impact of adjuvant radiation therapy on cognition and quality of life in adult patients with primary brain tumors.

PURPOSE: While treatments for primary brain tumors increase survival, they have cognitive sequelae. Neurocognition's anatomical distribution … d in various cognitive domains in addition to memory. The prefrontal subregions and the genu of the corpus callosum are more affected by the relationship with disease and surgical changes than by radiation exposure. Patients ongoing a course of radiotherapy do not benefit from concurrent cognitive rehabilitation. CONCLUSIONS: There is a correlation between the d …

A strike to the head: Parallels between the pediatric and adult human and the rodent in traumatic brain injury.

Traumatic brain injury (TBI) is a condition that occurs commonly in children from infancy through adolescence and is a global health concern … c and adult humans. We focus on the four brain regions most affected by TBI: the prefrontal cortex, corpus callosum, hippocampus, and hypothalamus. Each has its unique developmental projections and thus is impacted by TBI differently. This review aims to compare the healthy neurodevelopment of these four brain regions in humans to the developmental processes in r …

There was severe hypoplasia of pontocerebellar fiber …

A new type of blood-brain barrier aminoacidopathy underlies metabolic microcephaly associated with SLC1A4 mutations.

Mutations in the SLC1A4 transporter lead to neurodevelopmental impairments, spastic tetraplegia, thin corpus callosum and microcephaly in children. SLC1A4 catalyses obligatory amino acid exchange between neutral amino acids, but the physiopathology of SLC1A4 disease mutations and progressive microcephaly remain unclear. Here, we examined the phenotype and metabolic profile of three Slc1a4 mouse models: a constitutive Slc1a4-knockout mouse; a knock-in mouse with the major human Slc1a4 mutation (Slc1a4-K256E); and a selective knockout of Slc1a4 in brain endothelial cells (Slc1a4tie2-cre). We sho…

A presumed missense variant in the U2AF2 gene causes exon skipping in neurodevelopmental diseases.

U2 small nuclear RNA auxiliary factor 2 (U2AF2) is an indispensable pre-mRNA splicing factor in the early process of splicing. Recently, U2AF2 was reported as a novel candidate gene associated with neurodevelopmental disorders. Herein, we report a patient with a novel presumed heterozygous missense variant in the U2AF2 gene (c.603G>T), who has a similar clinical phenotype as the patient reported before, including epilepsy, intellectual disability, language delay, microcephaly, and hypoplastic corpus callosum. We reviewed the phenotypic and genetic spectrum of patients with U2AF2-related neurol…
