Abstract

This article briefly summarizes the historical events particularly these in Japan, in the kallikrein-kinin research and progress of the development of kallidinogenase (INN), enzyme with circulatory action. In 1926, E. K. Frey observed a drop in blood pressure in dogs following intravenous injection of the urine of human and other mammals into dogs. Intensive research showed that the urine contained a high-molecular active substance which dilated the peripheral arterial vessels. The substance was later called kallikrein after the Greek synonym for pancreas, as it occurred there at such a high concentration (Kraut et al., 1930) that this gland was thought to be its cite of origin. In 1930, kallikrein was commercially available as Padutin from Bayer, Germany. The product was introduced into Japan a few years later under the trade name of Kallikrein and was used for the treatment of circulatory disorders even during the Second World War. Kallikrein was again imported by Yoshitomi Pharmaceutical Industries, Ltd. in 1952. However, Kallikrein introduced after the War did not contain substance derived from the urine but from porcine pancreatic kallikrein as the active ingredient. It grew rapidly with its active promotion of the product...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.
