Abstract

Retroperitoneal sarcomas are rare mesenchymal neoplasms. Analysis of their characteristics and their impact upon a particular patient population is of significant importance to the surgeon. From 1970 to 1994, 63 adult patients underwent resection of primary retroperitoneal sarcomas at the University of Florida. A retrospective analysis was performed to determine the biologic behavior of these tumors, surgical management of primary and recurrent disease, predictive variables influencing survival, and the effect of multimodality therapy. There were 39 females and 24 males and the mean age was 55 years. The median weight of the tumors was 1,815 g (range 25 to 10,800 g). There were 33 percent leiomyosarcomas, 30 percent malignant fibrous histiocytomas, and 22 percent liposarcomas. Low-grade tumors accounted for 46 percent of the total, and grade was a significant predictor of survival (p=0.002). Seventy-eight percent of the lesions were totally resected, and this clearly influenced outcome (p<0.0001). In 75 percent of cases, adjacent organs were resected concurrently, and 34 percent of the tumors involved local vascular structures. Survival was enhanced by multiple resections in the 40 percent of patients who had a recurrence (p=0....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.
