Abstract

We evaluated the variation in serum testosterone in normal aging men and its relationship with erectile function. In a study that was not community based and during a free screening program for prostate cancer 1,071 men were invited to complete a sexual activity questionnaire, that is the abridged 5-item version of the International Index of Erectile Function (IIEF-5), as a diagnostic tool for erectile dysfunction. Possible scores on the IIEF-5 are 1 to 25 and erectile dysfunction was classified into 5 categories based on the scores, namely severe-1 to 7, moderate-8 to 11, mild to moderate-12 to 16, mild-17 to 21 and none-22 to 25. Serum total testosterone was measured between 8:00 and 10:00 a.m. in all men. Of the 1,071 men 965 (90.1%) were included in this study, of whom 88% were white and 12% were black. Mean age was 60.7 years. In this sample the prevalence of all degrees of erectile dysfunction was estimated to be 53.9%. The degree of erectile dysfunction was mild in 21.5% of cases, mild to moderate in 14.1%, moderate in 6.3% and severe in 11.9%. According to age the erectile dysfunction rate was 36.4% in the 40 to 49, 42.5% in the 50 to 59, 58.1% in the 60 to 69, 79.4% in the 70 to 79 and 100% in the 80 years and older gr...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.
