Abstract

TJ-114 (Tsumura Sairei-to) is a powdered extract made from 12 Chinese herbal drugs. TJ-114 is used against various nephrotic diseases and used as an inhibitory treatment for the side effects of glucocorticoids. We expected that TJ-114 would increase the survival ratio of rats given a high dose of glucocorticoid. Therefore, in this study, we investigated the combined effects of glucocorticoid and TJ-114 in rats. An ointment containing fluocinolone acetonide (FA) was applied on the back of 7-week-old Wistar male rats for various periods. TJ-114 was administered orally at the doses of 0.5, 1.0 or 2.0 g/kg simultaneously. The combination with TJ-114 suppressed the loss of body weight by FA. The survival ratio of the FA group was 50%, but it was 83% for the group treated with FA in combination with 0.5 g/kg TJ-114 and no deaths were observed in the other drug combined group. With a lower dose of FA, we investigated its hematological effects and determined the white blood cell (WBC) count. Although the lymphocytes were decreased by FA, the combination with TJ-114 depressed this decrease of lymphocytes significantly. Furthermore, TJ-114 significantly suppressed the insulin increase elicited by FA. Macroscopic observations showed atrop...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.
