Enzyme Feed Additive with Arazyme Improve Growth Performance, Meat Quality, and Gut Microbiome of Pigs.

The supplementation of pig diets with exogenous enzymes is widely used with the expectation that it will improve the efficiency of nutrient utilization, thereby, improving growth performance. This study aims to evaluate the effects of a 0.1% (/) multi-enzyme (a mixture of arazyme (2,500,000 Unit/kg), xylanase (200,000 Unit/kg) and mannanase (200,000 Unit/kg)) supplementation derived from invertebrate symbiotic bacteria on pig performance.

Arazyme in combination with dietary carbohydrolases influences odor emission and gut microbiome in growing-finishing pigs.

This study evaluated the effects of supplementing feed with arazyme and dietary carbohydrolases derived from invertebrate gut-associated symbionts on the noxious gas emissions, gut microbiota, and host-microbiome interactions of pigs. Here, 270 and 260 growing pigs were assigned to control and treatment groups, respectively. The tested feed additives contained a mixture of arazyme (2,500,000 Unit/kg) and synergetic enzymes, xylanase (200,000 Unit/kg) and mannanase (200,000 Unit/kg), derived from insect gut-associated symbionts in a 7.

Anti-inflammatory effect of Allium hookeri on carrageenan-induced air pouch mouse model.

Inflammation is a commonly observed immune reaction, and rheumatoid arthritis is a particularly severe inflammatory disease. In this study, we used an air pouch mouse model to evaluate the anti-inflammatory potential of Allium hookeri, which has both been used as a culinary material and a traditional medicine in south-eastern Asia for many years. Allium hookeri suppressed typical symptoms of inflammation, such as condensation of the air pouch membrane, and inhibited the expression of several inducible proinflammatory cytokines such as IL-1β, IL-6, IL-13, and TNF-α.

Genotoxicity and Single-Treatment Toxicity Evaluation of Mycoleptodonoides aitchisonii (Agaricomycetes) Water Extract.

Mushrooms have long been used worldwide for culinary and medicinal purposes because of their various nutrients and active constituents. The safety of mushrooms as a culinary ingredient requires validation. Although Mycoleptodonoides aitchisonii has long been used for culinary purposes in East Asia, it has not been authorized by a regulatory agency.

Estrogenic Activity of Hyperforin in MCF-7 Human Breast Cancer Cells Transfected with Estrogen Receptor.

Hyperforin, a major active compound of St. John's wort extract, affects estrogenic activity. In this study, the compound evoked estrogen response element-dependent luciferase activity and cell proliferation in MCF-7 cells.

Erythronium japonicum attenuates histopathological lung abnormalities in a mouse model of ovalbumin-induced asthma.

Asthma is a chronic lung condition that can induce mucus hypersecretion and pulmonary obstruction and may even cause death, particularly in children and older individuals. Erythronium japonicum (E. japonicum) is a traditional herb used in Korea and East Asian countries that has been found to exert free radical scavenging activity and anti-proliferative effects in human colorectal carcinoma cells.

Antimicrobial Constituents from Allium hookeri Root.

In this study, we partially purified the ethyl acetate soluble fraction of the ethanol extract of the root of Allum hookeri. We identified seven compounds, benzoic acid, tetradecanoic acid, hexadecanoic acid, ferulic acid, cinnamic acid, octadecanoic acid and hexanedioic acid, that have antimicrobial activity using GC-MS, and evaluated the antimicrobial susceptibility and MIC (minimum inhibitory concentration) against multidrug-resistant bacteria.

HPLC Analysis, Optimization of Extraction Conditions and Biological Evaluation of Corylopsis coreana Uyeki Flos.

A method for the separation and quantification of three flavonoids and one isocoumarin by reverse-phase high performance liquid chromatography (HPLC) has been developed and validated. Four constituents present in a crude ethanolic extract of the flowers of Coryloposis coreana Uyeki, were analyzed. Bergenin, quercetin, quercitrin and isosalipurposide were used as calibration standards.

St. John's Wort (Hypericum perforatum) stimulates human osteoblastic MG-63 cell proliferation and attenuates trabecular bone loss induced by ovariectomy.

Background/objecftives: The effect of St. John's Wort extract (SJW) on MG-63 cell proliferation and trabecular bone loss induced by ovariectomy was examined.

Materials/methods: Proliferation, expression of estrogen receptor (ER) α and ER β, and gene expressions of osteoprotegerin (OPG), osteocalcin (OC) and alkaline phosphatase (ALP) were examined in MG-63 cells treated with or without SJW.

Alginate oligosaccharide enhances LDL uptake via regulation of LDLR and PCSK9 expression.

The hepatic low-density lipoprotein (LDL) receptor (LDLR) plays a crucial role in lipoprotein metabolism by lowering the plasma LDL-cholesterol concentration, which reduces the risk for cardiovascular diseases. Although alginate oligosaccharide (AOS), prepared from degradation, has several pharmacological effects, it is not known whether AOS affects lipoprotein metabolism. This study was conducted to investigate whether AOS up-regulated LDLR expression and LDL uptake in vitro and in vivo, and the underlying molecular mechanism.

FK-3000 isolated from Stephania delavayi Diels. inhibits MDA-MB-231 cell proliferation by decreasing NF-κB phosphorylation and COX-2 expression.

The World Health Organization (WHO) has reported that cancer is one of the most prevalent diseases and a leading cause of death worldwide. Many anticancer drug development studies have been pursued over the last few decades and several viable drugs have been discovered, such as paclitaxel, topotecan and irinotecan. Previously, our research group uncovered the cytocidal and cytostatic effects of the plant Stephania delavayi Diels.

Inhibitory effect of Erythronium japonicum on the human breast cancer cell metastasis.

Background/objectives: In this study, the inhibitory effect of Erythronium japonicum extracts on the metastasis of MDA-MB-231 human breast cancer cell line was determined.

Pear pomace water extract inhibits adipogenesis and induces apoptosis in 3T3-L1 adipocytes.

Obesity occurs when a person's calorie intake exceeds the amount of energy burns, which may lead to pathologic growth of adipocytes and the accumulation of fat in the tissues. In this study, the effect and mechanism of pear pomace extracts on 3T3-L1 adipocyte differentiation and apoptosis of mature adipocytes were investigated. The effects of pear pomace extract on cell viability and the anti-adipogenic and proapoptotic effects were investigated via MTT assay, Oil red O staining, western blot analysis and apoptosis assay.

Distinct functional roles of peroxiredoxin isozymes and glutathione peroxidase from fission yeast, Schizosaccharomyces pombe.

To investigate the differences in the functional roles of peroxiredoxins (Prxs) and glutathione peroxidase (GPx) of Schizosaccharomyces pombe, we examined the peroxidase and molecular chaperone properties of the recombinant proteins. TPx (thioredoxin peroxidase) exhibited a capacity for peroxide reduction with the thioredoxin system. GPx also showed thioreoxin-dependent peroxidase activity rather than GPx activity.
