Abstract

The level of total prostate specific antigen (PSA) rises in acute prostatitis. The PSA fraction responsible for this increase and the evolution of the free/total PSA ratio are little known at the present time. We therefore carried out a prospective study of the evolution of total and free PSA levels and the free-to-total PSA ratio for one month after diagnosis of acute prostatitis. Between January 1999 and February 2001, 31 consecutive patients (mean age 51 years) were treated for acute prostatitis. No patient had a history of prostate cancer or of recent prostatitis. Measurement of C-reactive protein (CRP), total PSA and free PSA was done at days 0, 3, 10 and 30. During the first month of acute prostatitis and under an adapted antibiotherapy, CRP progressively decreased and returned to normal levels at about day 10. Total PSA level increased up to day 3 and then gradually decreased until at least the end of the first month. The level of free PSA decreased up to day 10 and was still low at one month, leading to a decrease in the free-to-total PSA ratio which was reached its lowest level at day 10 and was still low at one month. The increased level of total PSA in acute prostatitis is secondary to the proportional increase in bo...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.
