There are three main dietary groups in mammals: carnivores, omnivores, and herbivores. Currently, there is limited comparative genomics insight into the evolution of specializations mammals. Due to recent advances sequencing technologies, we were able perform in-depth whole genome analyses representatives these groups. We investigated carnivory by comparing 18 representative genomes from across Mammalia with carnivorous, omnivorous, herbivorous specializations, focusing on Felidae (domestic...
The 15,389-bp long complete mitogenome of the endangered red-spotted apollo butterfly, Parnassius bremeri (Lepidoptera: Papilionidae) was determined in this study. start codon for COI gene insects has been extensively discussed, and remained a matter some controversy. Herein, we propose that CGA (arginine) sequence functions as lepidopteran insects, on basis sequences including P. bremeri, well additional region from diverse taxonomic range species (a total 53 15 families). In our extensive...
The endolichenic fungus Xylaria grammica KCTC 13121BP showed strong nematicidal activity against Meloidogyne incognita. This study aimed to identify the metabolites and evaluate efficacy of strain as a biocontrol agent under pot field conditions.Bioassay-guided fractionation instrumental analyses led grammicin being identified metabolite. Because patulin is mycotoxic isomer known have antibacterial cytotoxic activities, several biological activities two compounds were compared. Grammicin...
We have determined the complete mitochondrial genome of yellow-spotted long horned beetle, Psacothea hilaris (Coleoptera: Cerambycidae), an endangered insect species in Korea. The 15,856-bp P. mitogenome harbors gene content typical animal and a arrangement identical to most common type found mitogenomes. As with all other sequenced coleopteran species, 5-bp TAGTA motif was also detected intergenic space sequence located between tRNA(Ser)(UCN) ND1 hilaris. 1,190-bp non-coding A+T-rich region...
Chemotaxonomic metabolite profiling of 62 indigenous Korean plant species was performed by ultrahigh performance liquid chromatography (UHPLC)-linear trap quadrupole-ion (LTQ-IT) mass spectrometry/mass spectrometry (MS/MS) combined with multivariate statistical analysis. In partial least squares discriminant analysis (PLS-DA), the clustered depending on their phylogenetic family, in particular, Aceraceae, Betulaceae, and Fagaceae were distinguished from Rosaceae, Fabaceae, Asteraceae. Quinic...
A new species of the genus Deladenus isolated from a dead red pine tree was characterized using morphometric and molecular DNA data. uljinensis n. sp. is by its lateral fields with six to seven lines, pharyngeal corpus without distinct median bulb lacking chamber, esophageal-intestinal junction located immediately behind nerve ring, hemizonid posterior excretory pore opening within contour or just at base hemizonid, vulva no vulval flaps, post-uterine sac rudimentary absent, vulva-anus...
A numerical analysis is performed to investigate the aerodynamic characteristics and static height stability of endplate anhedral angle on an aspect-ratio-one wing-in-ground effect. The shows that ground effect increases lift by high pressure lower surface, reduces drag, suction upper considerably enhances lift-drag ratio. endplate, which prevents high-pressure air from escaping out surface influence wing-tip vortex, further augments Irodov's criteria are also numerically evaluated in order...
It has been reported that acupuncture at GB34 can enhance neurogenesis in the subventricular zone (SVZ) of mice treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). However, signaling pathway plays a critical role needs to be established. Herein, we investigated neurogenesis-promoting mediated by acupuncture, focusing on extracellular signal-regulated kinase (ERK) signaling.Male 10-week-old C57BL/6 were intraperitoneally injected 30 mg/kg MPTP once daily for 5 days....
Currently, the palaeopteran lineages (insect orders Ephemeroptera and Odonata) that have a problematic relationship with neopteran are poorly represented by mitogenome sequences. In this study, we determined complete of oriental mayfly, Ephemera orientalis (Ephemeroptera: Ephemeridae), dragonfly Davidius lunatus (Odonata: Gomphidae). The 16 463 bp E. 15 912 D. many features typically detected in insect mitogenomes. Although initiation codon for COI gene is typical ATA, unusual no start was...
To evaluate the antimicrobial activities of an active compound isolated from culture broth Amphirosellinia nigrospora JS‐1675 against various plant pathogenic bacteria and fungi. While screening for bioactive secondary metabolites endophytic fungi, we found that A. showed strong in vitro antibacterial activity Ralstonia solanacearum. One (1) was identified as (4S, 5S, 6S)‐5,6‐epoxy‐4‐hydroxy‐3‐methoxy‐5‐methyl‐cyclohex‐2‐en‐1‐one. Growth most tested phytopathogenic inhibited by 1 ethyl...
Ginseng is known to have antiapoptotic, anti-inflammatory, and antioxidant effects. The present study investigated a possible role of Korean Red (KRG) in suppressing dopaminergic neuronal cell death the cleavage p35 p25 substantia nigra (SN) striatum (ST) using 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinson's disease mouse model.Ten-week-old male C57BL/6 mice were injected intraperitoneally with 30 mg/kg MPTP at 24-h intervals for 5 d, then administered KRG (1 mg/kg,...
To identify and compare venom components expression patterns, gland-specific transcriptome analyses were conducted for 14 Aculeate bees wasps. TPM (transcripts per kilobase million) values normalized using the average transcription level of a reference housekeeping gene (dimethyladenosine transferase). Orthologous component genes across bee wasp species identified, their relative abundance in each was determined by comparing values. Based on signal sequences transcripts, novel identified...
Rumex japonicus Houtt. (RJ) is widely distributed in Korea, Japan, and China. The root of RJ has traditionally been used to treat constipation, jaundice, hematemesis, dysfunctional uterine bleeding, gastrointestinal diseases. According recent studies, plants the genus have beneficial functionalities such as anti-microbial, antioxidative, anti-inflammatory effects. Inflammatory bowel disease, including Crohn's disease ulcerative colitis, a chronic inflammatory characterized by an abnormal...
The prevalence of antibiotic-resistant bacteria has become an immediate threat to public health. Antimicrobial peptides are attracting attention as a new source antibiotics due their ability prevent drug-resistances with fewer side effects. Spider venom is composed various bioactive substances multiple functionalities such antimicrobial and anti-inflammatory Here, RNA sequencing was conducted on the gland spider Pardosa astrigera, potential toxin peptide antibacterial properties selected via...
Purpose . Radiation-induced lung fibrosis (RILF) is a serious late complication of radiotherapy. In vitro studies have demonstrated that pentoxifylline (PTX) has suppressing effects in extracellular matrix production fibroblasts, while the antifibrotic action PTX alone using clinical dose yet unexplored. Materials and Methods We used micro-computed tomography (micro-CT) histopathological analysis to evaluate rat model RILF. Results Micro-CT findings showed density, volume loss, mediastinal...
Radiation-induced lung injury (RILI) due to nuclear or radiological exposure remains difficult treat because of insufficient clinical data. The goal this study was establish an appropriate and efficient minipig model introduce a thoracic computed tomography (CT)-based method measure the progression RILI. Göttingen minipigs were allocated control irradiation groups. most obvious changes in CT images after peribronchial opacification, interlobular septal thickening, volume loss. Hounsfield...
The emergence of pathogenic bacterial strains resistant to agrochemicals and the increasing demand for organic foods have led discovery new antibacterial metabolites that can be used either directly or as a lead molecule development synthetic bactericides. During screening fungal cultures, we found one strain, Aspergillus persii EML-HPB1-11, showed strong in vitro activity against Xanthomonas arboricola pv. pruni (Xap) with minimum inhibitory concentration (MIC) 10% fermentation broth...
