Abstract

Intracranial chondroid tumors are infrequently seen in neurosurgical practice. These tumors usually arise from cartilaginous synchondroses at the base of the skull, but occasionally from the pluripotential mesenchymal cells of the meninges. We present here a case of classic low-grade giant chondrosarcoma of the falx cerebri. This is only the second case of this variant reported in this location, and we summarize the diagnostic criteria with a brief review of literature. A 56-year-old female patient was admitted to the hospital with a history of progressive right-sided weakness occurring in the last 8 months and a recent grand mal seizure. Radiological evaluation demonstrated a large extra-axial mass in the left parafalcine area, suggesting a possible meningioma. An anterior interhemispheric approach enabled gross total removal of the tumor and a histologic diagnosis of a low-grade classic chondrosarcoma was made. The patient is currently stable and has shown no evidence of recurrence in more than 3 years without any adjuvant treatment. Intracranial cartilaginous tumors include classical, mesenchymal and myxoid chondrosarcomas in addition to benign chondromas. Parafalcine localization should be considered for all these variants ...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.
