A Snapshot of Early Transcriptional Changes Accompanying the Pro-Neural Phenotype Switch by NGN2, ASCL1, SOX2, and MSI1 in Human Fibroblasts: An RNA-Seq Study.

Direct pro-neural reprogramming is a conversion of differentiated somatic cells to neural cells without an intermediate pluripotency stage. It is usually achieved via ectopic expression (EE) of certain transcription factors (TFs) or other reprogramming factors (RFs). Determining the transcriptional changes (TCs) caused by particular RFs in a given cell line enables an informed approach to reprogramming initiation.

In Search of Spinal Muscular Atrophy Disease Modifiers.

The 5q Spinal Muscular Atrophy (SMA) is a hereditary autosomal recessive disease caused by defects in the survival motor neuron () gene encoding survival motor neuron (SMN) protein. Currently, it is the leading cause of infantile mortality worldwide. SMA is a progressive neurodegenerative disease with "continuum of clinical severity", which can be modulated by genetic and epigenetic factors known as disease modifiers (DMs).

Regulatory Peptide Pro-Gly-Pro Accelerates Neuroregeneration of Primary Neuroglial Culture after Mechanical Injury in Scratch Test.

The scratch test is used as an experimental in vitro model of mechanical damage to primary neuronal cultures to study the mechanisms of cell death in damaged areas. The involvement of NMDA receptors in processes leading to delayed neuronal death, due to calcium dysregulation and synchronous mitochondrial depolarization, has been previously demonstrated. In this study, we explored the neuroregenerative potential of Pro-Gly-Pro (PGP)-an endogenous regulatory peptide with neuroprotective and anti-inflammatory properties and a mild chemoattractant effect.

The Use of Thoracoscopic Release in the Surgical Correction of Thoracic Scoliosis in Children.

Purpose: To evaluate the effectiveness of endoscopic anterior release for thoracic scoliosis in children.

Material And Method: A retrospective analysis of the results of surgical treatment of 48 patients with idiopathic scoliosis of the thoracic spine aged 12-17 years, with a thoracic curve of more than 60°, was carried out.

Cases report: Mosaic structural variants of the gene in previously genetically unconfirmed multiple osteochondromas.

Multiple osteochondromas (MO) is a rare autosomal dominant skeletal disorder characterized by the development of multiple benign tumors known as osteochondromas. The condition is predominantly caused by loss-of-function variants in the or genes, facilitating relatively precise clinical diagnosis through established diagnostic criteria. Despite this, a notable percentage of MO cases (10%-20%) remains unresolved after sequencing coding regions and copy number analysis of both genes.

Metabolomics of head and neck cancer in biofluids: an integrative systematic review.

Introduction: Head and neck cancer (HNC) is the fifth most common cancer globally. Diagnosis at early stages are critical to reduce mortality and improve functional and esthetic outcomes associated with HNC. Metabolomics is a promising approach for discovery of biomarkers and metabolic pathways for risk assessment and early detection of HNC.

Juvenile idiopathic arthritis with systemic onset with inflammatory bone lesions: two case reports of patients successfully treated with canakinumab and experience gained from literature.

Unlabelled: Non-bacterial osteomyelitis (NBO) is a rare chronic inflammatory bone disease related to immune system dysregulation. This disease belongs to a family of autoinflammatory diseases. It often coexists with other TNF-α-mediated immune-mediated diseases such as juvenile idiopathic arthritis (JIA) and inflammatory bowel diseases.

Results: One hundred and seventy-five juvenile onset systemic sclerosis patients were evaluated, 142 females and 33 males.

Sliding tracheoplasty of complete tracheal cartilage rings in children.

Introduction: Complete tracheal rings are a rare malformation that occurs in 1 out of 100,000 live births. It is rare, isolated tracheal or tracheobronchial anomaly developed due to abnormal cartilage growth with formation of complete ring and often resulting in airway stenosis. Slide tracheoplasty, as it was originally described by Tsang et al.

Laparoscopic cyst enucleation is a promising technique for treatment of gastrointestinal tract duplications in children.

Background: Laparoscopic cyst enucleation has its advantages and limitations in treatment of gastrointestinal tract (GIT) duplications. It allows to avoid bowel resection in such locations as ileocecal valve. We introduced laparoscopic cyst enucleation with further bowel plasty using cyst muscle layer and without monopolar coagulation, for cyst dissection we used straight scissors.

Pediatric perioperative nutritional assessment and support.

Perioperative nutritional support reduces the healthcare burden of pediatric malnutrition and its risk. Strategic preventive, diagnostic and therapeutic nutritional management guidelines are now available for their optimization. The global needs for pediatric surgery are vast, amounting to millions of children and adolescents, with a corresponding workforce requirement, especially in less socioeconomically developed regions, and where malnutrition is endemic.

Our experience of using Losartan for esophageal stenosis in children with dystrophic form of congenital epidermolysis bullosa.

Introduction: Dystrophic epidermolysis bullosa (DEB) is one of the most severe forms of congenital epidermolysis bullosa and characterized by the formation of many surgical complications. Esophageal stenosis is a common complication of DEB and occurs in almost 76% of cases. Balloon dilatation (BD) under X-ray control is the main therapeutic technique, however conservative treatment is necessary to prevent restenosis.

Isoliquiritigenin Protects Neuronal Cells against Glutamate Excitotoxicity.

It is considered that glutamate excitotoxicity may be a major factor in the pathological death of neurons and mediate the development of neurodegenerative diseases in humans. Here, we show that isoliquiritigenin (ILG) at a concentration of 0.5-5 µM protects primary neuroglial cell culture from glutamate-induced death (glutamate 100 µM).

Insulin Diminishes Superoxide Increase in Cytosol and Mitochondria of Cultured Cortical Neurons Treated with Toxic Glutamate.

Glutamate excitotoxicity is involved in the pathogenesis of many disorders, including stroke, traumatic brain injury, and Alzheimer's disease, for which central insulin resistance is a comorbid condition. Neurotoxicity of glutamate (Glu) is primarily associated with hyperactivation of the ionotropic N-methyl-D-aspartate receptors (NMDARs), causing a sustained increase in intracellular free calcium concentration ([Ca]) and synchronous mitochondrial depolarization and an increase in intracellular superoxide anion radical (O) production. Recently, we found that insulin protects neurons against excitotoxicity by decreasing the delayed calcium deregulation (DCD).

Autoantibodies to Perilipin-1 Define a Subset of Acquired Generalized Lipodystrophy.

Acquired lipodystrophy is often characterized as an idiopathic subtype of lipodystrophy. Despite suspicion of an immune-mediated pathology, biomarkers such as autoantibodies are generally lacking. Here, we used an unbiased proteome-wide screening approach to identify autoantibodies to the adipocyte-specific lipid droplet protein perilipin 1 (PLIN1) in a murine model of autoimmune polyendocrine syndrome type 1 (APS1).
