Qualitative Analysis of Proteins in Two Snake Venoms, Gloydius Blomhoffii and Agkistrodon Acutus.

Objectives: Snake venom is a complex mixture of various pharmacologically active substances, such as small proteins, peptides, and organic and mineral components. This paper aims to identify and analyse the proteins in common venomous snakes, such as () and (), in Korea.

Methods: We used mass spectrometry, electrophoresis, N-terminal sequencing and in-gel digestion to analyse the proteins in these two snake venoms.

Structure of SARS-CoV-2 Spike Glycoprotein for Therapeutic and Preventive Target.

The global crisis caused by the coronavirus disease 2019 (COVID-19) led to the most significant economic loss and human deaths after World War II. The pathogen causing this disease is a novel virus called the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). As of December 2020, there have been 80.

The Progression of SARS Coronavirus 2 (SARS-CoV2): Mutation in the Receptor Binding Domain of Spike Gene.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) is a positive-sense single-stranded RNA (+ssRNA) that causes coronavirus disease 2019 (COVID-19). The viral genome encodes twelve genes for viral replication and infection. The third open reading frame is the spike () gene that encodes for the spike glycoprotein interacting with specific cell surface receptor - angiotensin converting enzyme 2 (ACE2) - on the host cell membrane.

Ginsenosides Rg5 and Rk1 Enriched Cultured Wild Ginseng Root Extract Bioconversion of : Effect on Scopolamine-Induced Memory Dysfunction in Mice.

Wild ginseng is known to contain additional physiologically and pharmacologically active substances than common ginseng. The utilization of this herb can be maximized by altering its composition via tissue culture generating adventitious roots. We enriched the content of specific ginsenosides and investigated their role in ameliorating memory impairment.
