Assessing systemic, developmental, and reproductive toxicity and estrogenicity of Korean red ginseng extract G1899 in juvenile Sprague-Dawley Rats.

Background: Korean red ginseng (KRG) is a product from ginseng roots, which is enriched with ginsenosides and has been utilized for a long time as an adaptogen to alleviate various physiological or disease conditions. While KRG is generally considered safe, conducting a thorough toxicological assessment of the spray-dried powder G1899 during the juvenile period is essential to establish its safety profile. This study aimed to assess the safety of G1899 during the juvenile period using Sprague-Dawley rats.

Modulating effects of heat-killed and live PSC102 on the immune response and gut microbiota of cyclophosphamide-treated rats.

In the present study, we investigated the potential immunomodulatory effects of heat-killed (hLR) and live PSC102 (LR; formerly PSC102) in RAW264.7 macrophage cells and Sprague-Dawley rats. RAW264.

Juvenile toxicity study of deer antler extract in rats.

Ethnopharmacological Relevance: Deer (Cervus elaphus Linnaeus) antler extract has been traditionally used in many Asian countries to prevent and treat various diseases. Deer antler extract is generally considered to be safe because humans have been exposed to it for a long time and it has been used as a tonic medicine originating from naturally occurring product. However, the comprehensive toxicological potential of deer antler extract during the juvenile period has not been investigated and its safety for juveniles remains unclear.

Bioactive Peptide Discovery from Edible Insects for Potential Applications in Human Health and Agriculture.

In the past decade, there has been fast-growing interest among researchers to discover bioactive peptides from edible insects and to evaluate their potential applications in the management of human, livestock, and plant health. This review summarizes current knowledge of insect-derived peptides and their potential role in tackling human health issues and solving agriculture problems by protecting crops and livestock against their pathogens. Numerous bioactive peptides have been identified from edible insect species, including peptides that were enzymatically liberated from insect proteins and endogenous peptides that occur naturally in insects.

In silico investigation of lead compounds against COVID-19 associated platelet activation and thromboembolism.

Hypercoagulability is frequently observed in patients with severe coronavirus disease-2019 (COVID-19). Platelets are a favorable target for effectively treating hypercoagulability in COVID-19 patients as platelet hyperactivity has also been observed. It is difficult to develop a treatment for COVID-19 that will be effective against all variants and the use of antivirals may not be fully effective against COVID-19 as activated platelets have been detected in patients with COVID-19.

Heat-killed PSC102 Ameliorates Impaired Immunity in Cyclophosphamide-induced Immunosuppressed Mice.

The immune functions of heat-killed PSC102 (hLR) were investigated in cyclophosphamide (CP)-treated immunosuppressed mice. BALB/c mice were randomly divided into five groups: normal control group, CP group, CP treated with levamisole (positive control group), and CP treated with low- and high-dose hLR. After receiving the samples for 21 days, mice were sacrificed, and different parameters, such as immune organ index, immune blood cells, splenocyte proliferation, lymphocyte subpopulations, cytokines, and immunoglobulins, were analyzed.

Serum biomarker-based osteoporosis risk prediction and the systemic effects of Trifolium pratense ethanolic extract in a postmenopausal model.

Background: Recent years, a soaring number of marketed Trifolium pratense (red clover) extract products have denoted that a rising number of consumers are turning to natural alternatives to manage postmenopausal symptoms. T. pratense ethanolic extract (TPEE) showed immense potential for their uses in the treatment of menopause complications including osteoporosis and hormone dependent diseases.

Prenatal developmental toxicity study of 2,4-dichlorobenzyl alcohol in rats.

Sore throat lozenges, which are over-the-counter drugs, contain 2,4-dichlorobenzyl alcohol (DCBA) as the primary ingredient. However, comprehensive data on the prenatal developmental toxicity of DCBA is limited. Therefore, this study was conducted to determine the effects of DCBA on pregnant rats and prenatal development.

Bis-diamine administration during pregnancy induces developmental and reproductive toxicities in rats.

Background: Bis-diamine was developed as amebicidal and male contraceptive agents; however, it is also reported to induce characteristic congenital heart defects especially in the cardiac conotruncal area of rats. Because of its characteristic congenital heart defects, bis-diamine-induced animal models can be used for studying congenital heart defects. However, comprehensive toxicological information regarding bis-diamine-induced congenital heart defects in this animal model is not available.

Trifolium pratense ethanolic extract alters the gut microbiota composition and regulates serum lipid profile in the ovariectomized rats.

Background: Trifolium pratense (red clover) ethanolic extract (TPEE) has been used as a popular over-the-counter remedy for the management of menopausal symptoms. Prolonged consumption of herbal extract has been shown to regulate the composition of gut microbiota. This study was designed to elucidate the influence of TPEE on the gut microbiota composition in the ovariectomized (OVX) rats.

Ginsenoside Rg3 reduces the adhesion, invasion, and intracellular survival of serovar Typhimurium.

Background: Invasive infections due to foodborne pathogens, including serovar Typhimurium, are prevalent and life-threatening. This study aimed to evaluate the effects of ginsenoside Rg3 (Rg3) on the adhesion, invasion, and intracellular survival of . Typhimurium.

Ethanolic Extract with Potential Anti-Allergic, Anti-Inflammatory, and Antioxidant Activities.

Atopic dermatitis (AD) is an allergic and chronic inflammatory skin disease. The present study investigates the anti-allergic, antioxidant, and anti-inflammatory activities of the ethanolic extract of (COFE) for possible applications in the treatment of AD. COFE inhibits the release of β-hexosaminidase from RBL-2H3 cells sensitized with the dinitrophenyl-immunoglobulin E (IgE-DNP) antibody after stimulation with dinitrophenyl-human serum albumin (DNP-HSA) in a concentration-dependent manner (IC = 0.

Methyl gallate and tylosin synergistically reduce the membrane integrity and intracellular survival of Salmonella Typhimurium.

Nymphaea tetragona Georgi (Nymphaceae) is traditionally used in Asia for the treatment of diarrhea, dysentery and fever. The plant contains various active compounds, including methyl gallate (MG) which are reported to inhibit bacterial virulence mechanisms. This study aimed to evaluate the alterations on viability, membrane potential and integrity of Salmonella enterica Serovar Typhimurium exposed to MG in combination with Tylosin (Ty), which is relatively inactive against Gram-negative bacteria, but it is commonly used as a feed additive in livestock.
