Magnetic resonance angiography in the management of childhood moyamoya disease: first choice for neurovascular scrutiny

Surgical Neurology

We performed magnetic resonance angiography (MRA) in 12 children with a suspected or angiographically proven moyamoya disease. MRA was performed by the three-dimensional, time-of-flight technique and, successfully depicted the primary abnormalities in the distal carotid arteries in 10 out of the 12 patients. In the other two patients, poor visualization of the intracranial vasculature strongly suggested the presence of the disease. On MRA, moyamoya vessels were visible in eight patients. The presence of anastomoses was also confirmed by MRA in seven of the 10 patients who had undergone encephalo-duro-arterio-synangiosis. Our findings suggest that MRA may be the tool of choice for selecting patients to undergo conventional angiography. However, establishing a definite diagnosis still requires some improvements in the delineation of the fine vasculature.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
