Abstract

AH 25086 B is a selective agonist of the newly determined 5-HT(1) receptors, which are sited mainly in the intracranial section of the carotid artery. According to experimental studies, the effect of AH 25086 B is decidedly more highly selective than that of ergotamine; the blood flow through the arteriovenous anastomoses of the internal carotid artery is clearly reduced, while the blood flow through the capillaries supplying the brain is increased. With AH 25086 B administered in an infusion rapid abolition of migraine attacks already in progress proved possible. The first 12 patients worldwide to receive this preparation were treated, some on several occasions, for a total of 21 migraine attacks: 7 received one infusion, 3 received two, 1 three, and 1 patient received five infusions. There were some side-effects with some infusions: nausea (18), vomiting (9), and photophobia (19). On average it took 31 min (range 10-60 min) for the headache to be relieved, regardless of the duration of migraine symptoms before the start of treatment. This was not a controlled study, but the results (14 very good, 6 good or satisfactory, in 21 attacks treated) were better than could have been expected by chance. Tolerance of the preparation wa...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.
