Absorbable mesh slings can prevent radiation-induced bowel injury when adjuvant pelvic radiotherapy is given in the early postoperative period. We hypothesized that the mesh sling technique is similarly effective during "sandwich" sequence adjuvant chemoradiation. Retrospective review. Tertiary care comprehensive cancer center. Nonrandomized series of 19 consecutive patients who underwent abdominoperineal resection and received postoperative sandwich sequence chemoradiation at Roswell Park Cancer Institute, Buffalo, NY, between January 1994 and September 1999. Twelve patients had an absorbable mesh sling placed at the completion of abdominoperineal resection. Seven patients did not have an absorbable mesh sling placed. Radiotherapy dose and gastrointestinal toxic effects. All 12 patients in the "mesh" group were able to receive full-dose radiotherapy with tumor bed boost (total dose, 54 Gy, 11 patients; 59.4 Gy, 1 patient). Only 3 of 7 patients in the "no mesh" group were able to receive a tumor bed boost (total dose, 46.8 Gy, 1 patient; 50.4 Gy, 3 patients; 54 Gy, 3 patients). Acute gastrointestinal toxic effects were minimal in the mesh group (grade 1, 10 patients; grade 2, 2 patients) compared with the no mesh group (grade 2...Continue Reading

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.

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.


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.
