Abstract

RCAS1 is a novel tumor marker, and there are no sufficient data about the utility of this antigen as a serum tumor marker and about its tumor specificity. We aimed at measuring the serum levels of RCAS1 in patients with pancreatic cancer and at determining its diagnostic efficacy. Sera collected from patients with pancreas adenocarcinomas (39 cases) and benign biliary and pancreatic diseases (19 cases) and from healthy volunteers (13 cases) were analyzed for RCAS1 and the results compared with CA19-9. The relation between serum RCAS1 and tumor stage was also evaluated. The serum RCAS1 levels exceeded the normal limit in 92.3, 26.3, and 23.0% of the patients with pancreatic cancer and benign biliary and pancreatic diseases and healthy volunteers, respectively. RCAS1 had a specificity similar to that of CA19-9 in pancreatic cancer, whereas RCAS1 had a higher sensitivity (p < 0.05). Both tumor markers had similar predictive values of positive and negative tests for pancreatic cancer. The RCAS1 level was less influenced than the CA19-9 level by biliary stenoses. The median serum levels of RCAS1 increased, as the tumor stage increased. RCAS1 is a valuable serum marker for the diagnosis of pancreatic cancer. The RCAS1 and CA19-9 leve...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.
