Abstract

Chrysophyllum cainito L., a traditional herbal medicine, could have the potential for management of hypertension due to presence of polyphenolic compounds. The extracts and fractions of the pulp of plant were evaluated for in vitro (inhibition of angiotensin I converting enzyme/ACE assay), ex vivo (isolated aorta relaxation assay) and in vivo (salt induced hypertensive rat assay). The alcoholic and aqueous extract (ALE and AQE respectively) of fruit of plant C. cainito was having 14.8 and 9.2% yield respectively. The fractionation with ethyl alcohol (EAF) and butanol (BTF) yielded 2.52 & 2.17% respectively from ALE and 0.46 & 0.31% respectively from AQE with respect to fruit pulp dry weight. More phenolic content was found in ALE (3.75±0.15 mg gallic acid equivalent or GAE g(-1) of dry power of fruit pulp) compared to AQE and maximum in ethyl acetate fraction of ALE (ALE-EAF) (2.32±0.21 mg GAE g(-1) of dry power of fruit pulp) among all fractions. ACE inhibition activity was found to be maximum in ALE-EAF 62.5±7.34%. While ex vivo study using isolated tissue of aorta showed again showed maximum activity (62.82±6.19 and 46.47±8.32% relaxation with 50 µg mL(-1) and 10 µg mL(-1) GAE concentration respectively). ALE-EAF reduced the...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.
