Minimal access nerve surgery and interventional magnetic resonance imaging

Abstract

Develop and assess the utility of novel minimal access techniques including percutaneous open-configuration interventional magnetic resonance imaging (iMRI), open surgery using open or closed/cylindrical iMRI systems, and minimal access open surgery with electromyographic guidance in a standard operating room. For more than 2500 percutaneous open iMRI procedures, 25 incisional surgery open iMRI cases, 3 incisional surgery closed/cylindrical iMRI cases, 25 computed tomography-guided percutaneous procedures, and more than 1000 minimal access incisional surgery cases in the standard operating room with electromyographic guidance, cycle time for intraoperative data collection and numbers of guidance events per case were assessed. Cycle time varied greatly. The minimum was for open surgery in the standard operating room with direct nerve stimulation for electromyography, requiring 10 to 15 seconds, which was applicable for dozens of assessments during the surgery and had negligible effects on total surgical time. Percutaneous procedures in the open iMRI environment allowed for 20 or 30 imaging events during a procedure, with cycle times of between 10 and 20 seconds. Incisional surgery in the open iMRI system had a cycle time of abou...Continue Reading

COVID-19

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

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.

Evolution of Pluripotency

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
