Utility of a Hydrolysate from Overproduced for Hypertension Treatment: Correlation between Physical Properties and Potent Anti-Hypertensive Activities.

Aquacultured fish are the richest natural source of protein. However, their overproduced biomass is often discarded due to production imbalance, causing considerable losses to the fishery industry. Therefore, it is necessary to utilize surplus fish and add value to overproduced fish.

Reversibility of sarcopenia by Ishige okamurae and its active derivative diphloroethohydroxycarmalol in female aging mice.

With the rapid increase in the elderly population worldwide, the number of people with sarcopenia has also increased significantly, and this disease is emerging as a medical and social issue. The development of pharmaceutics targeting sarcopenia is limited owing to the occurrence of side effects, and exercise therapy also has a limited scope of application. Therefore, it is necessary to develop safe and biocompatible agents to treat age-related sarcopenia.

Ishophloroglucin A, Isolated from , Alleviates Dexamethasone-Induced Muscle Atrophy through Muscle Protein Metabolism In Vivo.

The in vitro capacity of extract (IO) to improve impaired muscle function has been previously examined. However, the mechanism underlying IO-mediated muscle protein metabolism and the role of its component, Ishophloroglucin A (IPA), in mice with dexamethasone (Dexa)-induced muscle atrophy remains unknown. In the present study, we evaluated the effect of IO and IPA supplementation on Dexa-induced muscle atrophy by assessing muscle protein metabolism in gastrocnemius and soleus muscles of mice.

Diphlorethohydroxycarmalol Derived from Improves Behavioral and Physiological Responses of Muscle Atrophy Induced by Dexamethasone in an In-Vivo Model.

Muscle atrophy refers to the loss of skeletal muscle mass, myofiber size, and related physical functions such as walking speed or grip strength caused by aging or a lack of physical activity due to injury or illness and can also be attributed to excessive exposure to corticosteroids. (IO) and its active component, diphlorethohydroxycarmalol (DPHC), have been known to improve glucose homeostasis by controlling the contraction of skeletal muscles. Based on this idea, we hypothesized that the effects of DPHC and IO extract on muscle metabolism are associated with their role in improving muscle physical function.

Clinical Efficacy of the Antibiotic-Loaded Collagen Sponge During Arthroscopic Treatment of Acute Septic Arthritis of the Native Knee.

Background: To completely eliminate an infection, the antibiotic concentration must exceed the minimum inhibitory concentration for the causative pathogens. The antibiotic-loaded collagen sponge (ALCS) has been used to manage an infection through a high local concentration of antibiotics.

Purpose: To evaluate the clinical efficacy of ALCS in the arthroscopic treatment of patients with acute septic arthritis of the native knee.

Extract Attenuates Endothelial Cell Dysfunction by Modulation of Inflammation and Brown Adipocyte Function in Perivascular Fat Tissue.

It is well known that perivascular fat tissue (PVAT) dysfunction can induce endothelial cell (EC) dysfunction, an event which is related with various cardiovascular diseases. In this study, we evaluated whether extract (ECE) and pyrogallol-phloroglucinol-6,6-bieckol (PPB), one component of ECE, could attenuate EC dysfunction by modulating diet-induced PVAT dysfunction mediated by inflammation and ER stress. A high fat diet (HFD) led to an increase in the number and size of white adipocytes in PVAT; PPB and ECE attenuated those increases.

Antiobesity Effect of Fermented Chokeberry Extract in High-Fat Diet-Induced Obese Mice.

Black-fruited chokeberries (Aronia melanocarpa), growing mainly in the Central and Eastern European countries, have health benefits due to the high concentrations of polyphenolic compounds. However, a strong bitter taste of chokeberries limits its usage as functional food. We hypothesized that the fermented A.

Expression of the sweetpotato R2R3-type IbMYB1a gene induces anthocyanin accumulation in Arabidopsis.

R2R3-type MYB transcription factors (TFs) play important roles in transcriptional regulation of anthocyanins. The R2R3-type IbMYB1 is known to be a key regulator of anthocyanin biosynthesis in the storage roots of sweetpotato. We previously showed that transient expression of IbMYB1a led to anthocyanin pigmentation in tobacco leaves.

Silver-stained fibrin zymography: separation of proteases and activity detection using a single substrate-containing gel.

A new zymogram method, silver-stained fibrin zymography, for separation of protease bands and activity detection using a single substrate gel, was developed. The method takes advantage of the nanoscale sensitivity of both zymography and silver staining. After SDS-PAGE in a gel containing fibrin, the gel was incubated in enzyme reaction buffer and the zymogram was silver-stained.

Hypouricemic effects of anthocyanin extracts of purple sweet potato on potassium oxonate-induced hyperuricemia in mice.

Gout is a clinical syndrome in which tissue damage is induced by a chronic metabolic disorder associated with increased concentrations of uric acid in the blood. The study investigated the hypouricemic effects of anthocyanin extracts from purple sweet potato (APSP), and allopurinol, on serum uric acid levels in hyperuricemic mice. It was found that administration of a single oral dose of 100 mg/kg APSP to such animals reduced the serum uric acid concentration to 4.

Regioselective deglycosylation of onion quercetin glucosides by Saccharomyces cerevisiae.

Bioconversion of quercetin glucosides using four generally recognized as safe (GRAS) organisms (Aspergillus oryzae, Bacillus subtilis, Lactobacillus plantarum, and Saccharomyces cerevisiae) was evaluated by measuring changes in the levels of quercetin compounds of onion. Of the four organisms, S. cerevisiae increased the content of quercetin-3-O-β-D-glucoside (III; isoquercitrin) and quercetin (IV), whereas decreasing quercetin-3,4'-O-β-D-glucoside (I) and quercetin-4'-O-β-D-glucoside (II).

A new fibrinolytic enzyme (55 kDa) from Allium tuberosum: purification, characterization, and comparison.

Chives have been used both as food and as medicine. Previously, two fibrinolytic enzymes, ATFE-I (90 kDa) and ATFE-II (55 kDa), were identified in chives (Allium tuberosum), a perennial herb. In the present work, ATFE-II was purified by ion-exchange chromatography followed by gel filtration.

Purification and characterization of a novel thermoacid-stable fibrinolytic enzyme from Staphylococcus sp. strain AJ isolated from Korean salt-fermented Anchovy-joet.

A novel fibrinolytic enzyme (AJ) was purified from Staphylococcus sp. strain AJ screened from Korean salt-fermented Anchovy-jeot. Relative molecular weight of AJ was determined as 26 kDa by using SDS-PAGE and fibrin zymography.

A method for direct application of human plasmin on a dithiothreitol-containing agarose stacking gel system.

A new simplified procedure for identifying human plasmin was developed using a DTT copolymerized agarose stacking gel (ASG) system. Agarose (1 %) was used for the stacking gel because DTT inhibits the polymerization of acrylamide. Human plasmin showed the lowest activity at pH 9.
