Abstract

The authors investigated the optima dose (efficacy and safety) of moxisylyte, an alpha-blocking agent, in a double-blind placebo-controlled crossover study in 30 patients. The origin of the erectile dysfunction was predominantly psychological in 14 patients and neurological in 16 patients. Each patient received 4 intracavernous injections in a randomized order (placebo, 10, 20, 30 mg of moxisylyte) at 7-day intervals. Regardless of the dose, moxisylyte induced significantly greater penile responses than placebo on all erection criteria. The frequency of responses allowing sexual intercourse appeared to be dose-dependent in the two aetiological groups. The erectile responses most frequently obtained were complete rigidity in the "neurological" group and tumescence in the "psychological" group. The safety was excellent for 95.6% of injections and no case of priapism was observed. One patient (neurological patient) experienced two prolonged erections after the dose of 20 mg and another patient (psychological patient) reported 2 headaches after the dose of 30 mg. No pain was experienced on injection. Moxisylyte is very well tolerated and is able to induce an erectile response from the dose of 10 mg. This dose appears to be sufficie...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.
