Acute Ischemic Stroke in a Teenage Patient: Are We "MIS-C"ing Something?

The reported annual incidence of acute ischemic stroke (AIS) among pediatric and young adults is 1-13/100,000. In adults, ischemic stroke is attributed to several risk factors such as smoking, hypertension, atherosclerosis, and diabetes. Alternatively, pediatric ischemic stroke is associated with a broad spectrum of etiologies including prematurity, congenital heart disease, arteriopathies like moyamoya, chronic inflammatory disease, sickle cell, hypercoagulability, and malignancy.

Surgical Treatment of Adolescent Idiopathic Scoliosis with the ApiFix Minimal Invasive Dynamic Correction System-A Preliminary Report of a 24-Month Follow-Up.

Adolescent idiopathic scoliosis (AIS) is a three-dimensional growth disorder. Corrective surgical procedures are the recommended treatment option for a thoracic angle exceeding 50° and a lumbar major curve of 40°. Over the past few years, dynamic growth modulation implants have been developed as alternatives to permanent fusion.

Basic fibroblast growth factor controls migration in human mesenchymal stem cells.

Little is known about the migration of mesenchymal stem cells (MSCs). Some therapeutic approaches had demonstrated that MSCs were able to regenerate injured tissues when applied from different sites of application. This implies that MSCs are not only able to migrate but also that the direction of migration is controlled.

Human bone marrow stroma cells display certain neural characteristics and integrate in the subventricular compartment after injection into the liquor system.

Because the neural differentiation capacity of bone marrow stromal cells (BMSCs) is still a matter of controversial debate, we performed a thorough investigation into the differentiation capacity of human BMSCs and examined their therapeutic potency. BMSCs were isolated from the femur and kept in cell cultures with various cultivation protocols being applied. In standard culture conditions using a fetal calf serum-enriched medium, while not exhibiting a neural phenotype, the majority of cells expressed a variety of neuronal marker proteins as well as the astrocyte marker GFAP.

Phospho-eNOS Ser-114 in human mesenchymal stem cells: constitutive phosphorylation, nuclear localization and upregulation during mitosis.

Activity of endothelial nitric oxide synthase (eNOS) is modulated by protein-protein interaction and phosphorylation at specific serine or threonine residues. Using immunofluorescence analysis we show here that proliferating mesenchymal stem cells (MSCs) derived from human bone marrow exhibit cytosolic and pronounced nuclear localization of eNOS. Examination of phosphorylated eNOS subspecies revealed that eNOS phosphorylated at Ser-114 is heavily enriched in the nucleus, whereas eNOS phosphorylated at Ser-1177 is localized at filamentous structures in the cytosol that are abundant in the perinuclear region.
