Aims: Dysphagia is a major clinical concern in Parkinson's disease (PD). However, the relationship between the development of phase-specific dysphagia and the regional brain glucose metabolism remains unclear. Our objective was to investigate the distributions of brain glucose metabolism specific to oral and pharyngeal phases of dysphagia in PD.

The antifungal activity of thymol against F23 and F15 in onions was examined through direct treatment with amended media and gaseous treatment with I-plates (plastic plates containing central partitions). The protective and curative control efficacy of thymol was examined 24 h before and after the inoculation of onion bulbs with the fungal isolates. Mycelial growth, sporulation, and spore germination of the isolates were inhibited on potato dextrose agar amended with various concentrations of thymol or acetic acid (positive control).

The genus (Cladosporiaceae, Capnodiales) is a large genus of Ascomycota. Although the genus is mostly reported as saprobes from a wide range of substrates with a worldwide distribution, members of this genus comprise infectious agents in animals and plants. Of those, is a common saprophytic fungus and has been found to be a human opportunistic pathogen and plant pathogen.

Walnut () is one of the main tree crops cultivated for nut production in South Korea with an estimated production of about 1,189 tons per year (Korea Forest Service 2020). In August 2021, anthracnose symptoms, including dark, depressed, irregularly shaped lesions on fruits and leaves of walnut cv. Sinlyeong, were observed at three orchards in Nonsan (36°10'22.

In our previous study, three bacterial strains, KU143, KU313, and AS15, were selected as effective biocontrol agents against on stored rice grains. In this study, we evaluated the inhibitory effects of the volatiles produced by the strains on growth and aflatoxin production on stored rice grains. The three strains significantly reduced mycelial growth of in dual-culture assays compared with the negative control strain, KU408, and an untreated control.

Species of the genus Chryseobacterium belonging to the family Flavobacteriaceae are nonmotile, yellow-pigmented, and rod-shaped bacteria, some of which were frequently isolated from soil or plant-related materials. Here, we present draft genome sequences of three type strains of Chryseobacterium, which contain genes related to plant growth promotion, colonization, or stress adaptation.

Background: The effect of methyl jasmonate (MJ) on ginsenoside production in different organs of ginseng (Panax ginseng Meyer) was evaluated after the whole plant was dipped in an MJ-containing solution. MJ can induce the production of antioxidant defense genes and secondary metabolites in plants. In ginseng, MJ treatment in adventitious root resulted in the increase of dammarenediol synthase expression but a decrease of cycloartenol synthase expression, thereby enhancing ginsenoside biosynthesis.

Ginsenosides are glycosylated triterpenes that are considered to be important pharmaceutically active components of the ginseng (Panax ginseng 'Meyer') plant, which is known as an adaptogenic herb. However, the regulatory mechanism underlying the biosynthesis of triterpene saponin through the mevalonate pathway in ginseng remains unclear. In this study, we characterized the role of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) concerning ginsenoside biosynthesis.

The aim of this study was to develop novel long-acting glucagon-like peptide 1 (GLP-1) analogs resistant to dipeptidyl peptidase-IV (DPP-IV). We constructed three fusion proteins comprising GLP-1 and the human immunoglobulin gamma heavy chain (IgG-Fc); wild-type GLP-1 and IgG-Fc (GLP-1/IgG-Fc) and two N-terminal-extended fusion proteins in which an additional Ala (A) or Gly (G) was located on the N-terminus of GLP-1 (A-GLP-1/IgG-Fc or G-GLP-1/IgG-Fc). The fusion proteins expressed in CHO-K1 cells were secreted into medium and purified by Protein A affinity chromatography.

This study was designed to investigate the possibility that mtDNA mutations might arise in inflammatory or chronically damaged nasal polyp tissue from 23 patients. Thirteen patients (57%) displayed nasal polyp tissue-specific mtDNA mutations in the hypervariable segment of the control region and cytochrome b gene, which were not found in the corresponding blood cells and/or adjacent normal tissue. Nasal polyp tissue-specific length heteroplasmic mutations were also detected in nucleotide position (np) 303-315 homopolymeric poly C track (39%), np 514-523 CA repeats (17%) and np 16184-16193 poly C track (30%).

Stored rice was collected from rice processing complexes of National Agricultural Cooperative Federation of 11 regions in Korea to evaluate the occurrence of fungi and bacteria and to identify the predominant fungi and bacteria to the genus levels. Most rice samples generally produced the higher levels of fungi and bacteria than white rice. The occurrence of fungi and bacteria varied in various locations of Korea.
