Effects of the purified dry extract of fermented ginseng BST204 on muscle fiber regeneration.

Background: Sarcopenia and muscular dystrophy are two muscle diseases. In cancer patients, cancer cachexia induces continuous weight loss and muscle loss due to the disease itself or the use of anticancer drugs. Cachexia occurs in up to 80% of cancer patients.

Osteoarthritis improvement effect of var. extract in relation to genotype.

To determine whether SNPs of osteoarthritis (OA)-related genes predict the effect of var. (CZ) extract in OA patients with OA. To analyze correlations between CZ extract effects in humans and their genotypes, 121 Korean patients with OA were recruited.

Antiviral effects of human placenta hydrolysate (Laennec) against SARS-CoV-2 in vitro and in the ferret model.

The COVID-19 pandemic has caused unprecedented health, social, and economic crises worldwide. However, to date, there is an only a limited effective treatment for this disease. Human placenta hydrolysate (hPH) has previously been shown to be safe and to improve the health condition in patients with hyperferritinemia and COVID-19.

Potential Therapeutic Effect of Micrornas in Extracellular Vesicles from Mesenchymal Stem Cells against SARS-CoV-2.

Extracellular vesicles (EVs) are cell-released, nanometer-scaled, membrane-bound materials and contain diverse contents including proteins, small peptides, and nucleic acids. Once released, EVs can alter the microenvironment and regulate a myriad of cellular physiology components, including cell-cell communication, proliferation, differentiation, and immune responses against viral infection. Among the cargoes in the vesicles, small non-coding micro-RNAs (miRNAs) have received attention in that they can regulate the expression of a variety of human genes as well as external viral genes via binding to the complementary mRNAs.

BST204 Protects Dexamethasone-Induced Myotube Atrophy through the Upregulation of Myotube Formation and Mitochondrial Function.

BST204 is a purified ginseng dry extract that has an inhibitory effect on lipopolysaccharide-induced inflammatory responses, but its effect on muscle atrophy is yet to be investigated. In this study, C2C12 myoblasts were induced to differentiate for three days followed by the treatment of dexamethasone (DEX), a corticosteroid drug, with vehicle or BST204 for one day and subjected to immunoblotting, immunocytochemistry, qRT-PCR and biochemical analysis for mitochondrial function. BST204 alleviates the myotube atrophic effect mediated by DEX via the activation of protein kinase B/mammalian target of rapamycin (Akt/mTOR) signaling.

Anti-Osteoarthritic Mechanisms of in MIA-Induced Osteoarthritic Rats and Interleukin-1β-Induced SW1353 Human Chondrocytes.

var. (CZ), which has traditionally been used as a oriental tea in Asia, is known to have anti-inflammatory effects in osteoarthritis (OA). But the mechanism of these effects has not been made clear and it needs to be elucidated specifically for the clinical use of CZE in OA.

Effects of Human Placenta Extract (Laennec) on Ligament Healing in a Rodent Model.

Rich in bioactive substances such as amino acids and peptides, Laennec (human placenta hydrolysate) has been widely used to control various types of musculoskeletal pain. However, the effects of Laennec on tendon and ligament injuries are not clearly understood. In the present study, Laennec was tested to identify its in vivo effects on ligament injury in an animal model and its in vitro effects on tendon-derived fibrocytes.

Human Placenta Hydrolysate Promotes Liver Regeneration via Activation of the Cytokine/Growth Factor-Mediated Pathway and Anti-oxidative Effect.

Liver regeneration is a very complex process and is regulated by several cytokines and growth factors. It is also known that liver transplantation and the regeneration process cause massive oxidative stress, which interferes with liver regeneration. The placenta is known to contain various physiologically active ingredients such as cytokines, growth factors, and amino acids.

Efficacy of A/H1N1/2009 split inactivated influenza A vaccine (GC1115) in mice and ferrets.

To evaluate the efficacy of a non-adjuvant A/H1N1/2009 influenza A vaccine (GC1115), we demonstrated the immunogenicity and protective efficacy of GC1115 in mouse and ferret models. The immunogenicity of GC1115 was confirmed after intramuscular administration of 1.875, 3.

Preclinical evaluation of the efficacy of an H5N8 vaccine candidate (IDCDC-RG43A) in mouse and ferret models for pandemic preparedness.

Because H5N1 influenza viruses continuously threaten the public health, the WHO has prepared various clades of H5N1 mock-up vaccines as one of the measures for pandemic preparedness. The recent worldwide outbreak of H5Nx virus which belongs to clade 2.3.

Antioxidant effect of human placenta hydrolysate against oxidative stress on muscle atrophy.

Sarcopenia, which refers to the muscle loss that accompanies aging, is a complex neuromuscular disorder with a clinically high prevalence and mortality. Despite many efforts to protect against muscle weakness and muscle atrophy, the incidence of sarcopenia and its related permanent disabilities continue to increase. In this study, we found that treatment with human placental hydrolysate (hPH) significantly increased the viability (approximately 15%) of H O -stimulated C2C12 cells.

Anti‑apoptotic effects of human placental hydrolysate against hepatocyte toxicity in vivo and in vitro.

Apoptosis and oxidative stress are essential for the pathogenesis of acute liver failure and fulminant hepatic failure. Human placental hydrolysate (hPH) has been reported to possess antioxidant and anti‑inflammatory properties. In the present study, the protective effects of hPH against D‑galactosamine (D‑GalN)‑ and lipopolysaccharide (LPS)‑induced hepatocyte apoptosis were investigated in vivo.

Anti-stress effects of human placenta extract: possible involvement of the oxidative stress system in rats.

Background: Human placenta hydrolysate (hPH) has been utilized to improve menopausal, fatigue, liver function. Its high concentration of bioactive substances is known to produce including antioxidant, anti-inflammatory and anti-nociceptive activities. However, its mechanisms of stress-induced depression remain unknown.

Evaluation of two different enzyme-linked immunosorbent assay for severe fever with thrombocytopenia syndrome virus diagnosis.

To develop the large scale serological assay for severe fever with thrombocytopenia syndrome virus (SFTSV) infection, we evaluated two different enzyme-linked immunosorbent assay (ELISA) methods using nucleocapsid protein (NP) and Gn proteins of CB1 (genotype B) SFTSV strains. The NP-based ELISA tests showed more sensitive with broad cross-reactivity between two different genotype A and B strains compared with those of Gn-based ELISA tests. However, Gn-based ELISA showed more genotype specificity and specificity.

Epidemiology of severe fever and thrombocytopenia syndrome virus infection and the need for therapeutics for the prevention.

Over the past ten years there has been a marked increase in cases of severe fever and thrombocytopenia syndrome in East Asia. This tick-borne hemorrhagic fever presents along with clinical signs including high fever and leukopenia. In addition to humans, the virus has also been detected with shared genetic homology in farm animals including goats, cattle, horses, and pigs.

Human placental extract exerts hair growth-promoting effects through the GSK-3β signaling pathway in human dermal papilla cells.

Human placental extract (HPE) is widely used in Korea to relieve fatigue. However, its effects on human dermal papilla cells (hDPCs) remain unknown. In the present study, in an effort to develop novel therapies to promote hair growth, we screened HPE.

Protective Effect of Flos Lonicerae against Experimental Gastric Ulcers in Rats: Mechanisms of Antioxidant and Anti-Inflammatory Action.

Flos Lonicerae is one of the oldest and most commonly prescribed herbs in Eastern traditional medicine to treat various inflammatory diseases. In the present study, we investigated the effects of ethyl acetate fraction of Flos Lonicerae (GC-7101) on experimental gastric ulcer models and its mechanisms of action in gastric ulcer healing. The pharmacological activity of GC-7101 was investigated in rats on HCl/EtOH, indomethacin, water immersion restraint stress induced acute gastric ulcer, and acetic-acid-induced subchronic gastric ulcer.
