Abstract

To develop a reproducible in vivo model for the growth of human meningiomas, meningiomas from 16 patients were implanted into the subrenal capsule of the nude mouse. In eight experiments solid tumor implants taken directly from surgical specimens were used, in four experiments the implants were made from early-passage monolayer cell cultures, and in four experiments both techniques were used. Successful tumor growth was observed in 10 (83%) of the 12 solid tumor implants and in six (75%) of the eight implants from cell cultures. The size and neovascularization of these tumors were serially determined over a 3-month period. Tumor doubling occurred in 1 to 3 weeks in all of the solid tumor implant group. In the group of six tumors successfully implanted from cell cultures, three doubled in 1 to 3 weeks and three grew more rapidly, reaching 10 to 20 times their original volume. Neovascularity occurred in the tumors within 3 weeks of implantation. Each of the solid tumor implants had a histological pattern similar to that of the corresponding original specimen. Only three of those implanted from cell cultures were similar to the original tumor; the other three displayed features characteristic of malignant meningioma. These studies...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.
