The structures phlorotannins were determined on basis spectroscopic analysis, including NMR and mass spectrometry analysis. activities isolated compounds evaluated by free radical scavenging in both vitro cellular systems. anti-inflammatory effects determining their inhibitory production nitric oxide (NO) prostaglandin E2 (PGE2)...

Abstract Background Porcine reproductive and respiratory syndrome virus (PRRSV) is a macrophage-tropic arterivirus with extremely high genetic pathogenic heterogeneity that causes significant economic losses in the swine industry worldwide. PRRSV can be divided into two species [PRRSV1 (European) PRRSV2 (North American)] usually diagnosed genetically differentiated several lineages based on ORF5 gene, which constitutes only 5% of whole genome. This study was conducted to achieve nonselective...

Research on tissue preservation, including cortical bone, skin, nerves, and vessels in glycerol bone honey, has shown positive results. On the other hand, relatively few studies have been performed fascia comparisons between different preservation methods remain scarce. This vitro study compared biomechanical properties of five preserving lata. The control group underwent testing immediately after decellularization, while groups were stored glycerol, deep freezer, lyophilizer, liquid...

Hydrogen mobility is expected to be a crucial element in decarbonizing fossil fuel-based transportation. In South Korea, hydrogen has successfully formed an early market led by fuel cell passenger cars under strong support policies. Nevertheless, the vehicle (FCV) still its infancy, and current challenges must overcome achieve mass-market adoption. This study aims identify diffusion of FCVs Korea. We identified key facing from consumer perspective with data latest FCV customer survey. The...

The concentrations of functional compounds and micronutrients chicken breast from native chickens were compared with those broiler. Totally 200 male chicks a commercial (HH) three newly bred strains (2A, 2C, 2D) reared for about 2 kg final live weight up to 12 wk. After slaughtered, antioxidant dipeptides, reducing sugar, free amino acids, vitamins, minerals the muscles analyzed broilers similar weight. Mostly had higher contents carnosine, anserine, sugar than Especially HH implied highest...

Two intact male dogs were evaluated for symptoms, including hematuria, prostatomegaly, anuria, lethargy, and abdominal mass. Presurgical evaluations, complete physical examinations, blood radiography with contrast (only in Case 2), ultrasonography, computed tomography magnetic resonance imaging 1), performed. A paraprostatic cyst was diagnosed initially, laparoscopic exploration surgery Complete resection performed case 1, whereas partial omentalization 2. Histopathological examination of...

Elderly people avoid eating red meat and dried product due to its texture stiffness; they deprive them of rich sources nutrients. In addition, food-related diseases are exponentially increasing using synthetic additives in food products. Therefore, this research aimed develop semi-dried goat jerky considering geriatric preferences by natural tenderizers nitrate. Four treatments were formulated negative control (NC [synthetic nitrite without tenderizers]), positive (PC [Swiss chard T1 (Swiss...

Porcine reproductive and respiratory syndrome virus (PRRSV) has caused huge economic losses in the global swine industry. Frequent genetic variations this cause difficulties controlling accurately diagnosing PRRSV.In study, we investigated characteristics of PRRSV-1 PRRSV-2 circulating Korea from January 2018 to September 2021 evaluated three one-step real-time reverse transcription polymerase chain reaction (RT-PCR) assays.A total 129 lung samples were collected, consisting 47 for PRRSV-1,...

The effects of phosphate alternatives on meat quality in marinated chicken were investigated with the application chilling and freezing. Breast muscles injected solution green weight containing 1.5% NaCl 2% sodium tripolyphosphate (STPP) or alternatives. Treatment variables consisted no [control (-)], 0.3% (+)], prune juice (PJ), oyster shell, nano-oyster yeast lemon extract (YLE) powder. One-third samples stored at 4°C for 1 d, rest meats kept -18°C 7 d. In chilled meat, a lower drip loss...

The carcass and meat quality of new native chicken strains (A, C, D) being developed in the Golden Seed Project for Samgyetang were compared with a commercial (Hanhyup No. 3, H) Baeksemi (white semi broiler, W) strains. In total, 250 male chicks raised under same feeding raising conditions 5 weeks. After slaughter, weight percentage yield parts from each strain measured physicochemical traits (general composition, color values, fatty acid sensory evaluation) breast muscles comparatively...

This study examined the effects of different wet-aging times on physicochemical characteristics and microbial profile longissimus lumborum (LL) biceps femoris (BF) muscles from Korean native black goat (KNBG) meat. The water holding capacity (WHC), pH, cooking loss, shear force, meat color, free amino acid, total bacteria, coliform count KNGB were analyzed at 0, 5, 10, 15 days 4°C under vacuum packaging. results showed that led to significant pH variations between throughout aging period....

The purpose of this study is to examine the status music education in current integrated curriculum called ‘Pleasant life’ for 1st and 2nd graders elementary school as well assess community's perception it. literature review focused on importance early years, development life,’ curriculum's contents. A total 9 questionnaire items centered four main areas were created assessed appropriateness validity through a ploit external expert advice. Researchers analyzed 1,179 responses collected...

This study examines the evolution of Korean traditional music content in “Pleasant Life” curriculum for 1st and 2nd grade elementary school students. The analysis spans from 4th national to 2007, 2009, 2015 revisions, during which integrated subjects were introduced. findings indicate that since 2007 revision, start units led a reduction diversity genres, as well simplification content, became heavily focused on songs games. trend accelerated after introduction subject 2009 further narrowing...

The treatment of livestock fatalities caused by epidemic diseases must be timely. Simultaneously, the contaminated excreta and bedding materials also treated on site without removal. composting manure with bulking is widely used farm, temperature during reaches over 60°C under appropriate conditions moisture oxygen, a suitable carbon to nitrogen ratio. These characteristics can applied degradation dead livestock. Hence, this study was conducted evaluate degradability mortalities material...

Elderly people avoid eating red meat due to its texture and stiffness; they deprive them of rich sources nutrients. In addition, food-related diseases are exponentially increasing using synthetic additives in food products. Therefore, this research aimed develop semi-dried goat jerky considering geriatric preferences by natural tenderizers nitrate. Four treatments were formulated NC (synthetic nitrite without tenderizers), PC (Swiss chard T1 with pineapple powder), T2 tomato powder). had...

Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most important pathogens in swine industry worldwide. In Korea, Fostera PRRS commercial modified live (MLV) vaccines have been used since 2014 to control PRRSV infection. this study, two PRRSV-2 strains (20D160-1 21R2-63-1) were successfully isolated, their complete genomic sequences determined. Genetic analysis showed that isolates recombination events between P129-like strain derived from MLV vaccine lineage 1. The...
