The gadB gene encoding glutamate decarboxylase (GAD) from Lactobacillus plantarum was cloned and expressed in Escherichia coli. recombinant enzyme exhibited maximal activity at 40 °C pH 5.0. 3D model structure of L. GAD proposed that its C-terminal region (Ile454–Thr468) may play an important role the dependence catalysis. Accordingly, C-terminally truncated (Δ3 Δ11 residues) mutants were generated their activities compared with wild-type different values. Unlike GAD, showed pronounced...
Climate change increases global temperatures, which is lethal to both livestock and humans. Heat stress known as one of the various stresses, dairy cows react sensitively high-temperature stress. We aimed better understand effects heat on health observing biological changes. Individual were divided into normal (21–22 °C, 50–60% humidity) high temperature (31–32 80–95% humidity), respectively, for 7-days. performed metabolomic transcriptome analyses blood gut microbiomes feces. In group, nine...
Heat stress (HS) negatively impacts pig production and swine health. Therefore, to understand the genetic metabolic responses of pigs HS, we used RNA-Seq high resolution magic angle spinning (HR-MAS) NMR analyses compare transcriptomes metabolomes Duroc (n = 6, 3 barrows gilts) exposed heat (33 °C 60% RH) with a control group (25 RH). HS resulted in differential expression 552 (236 up, 316 down) 879 (540 339 genes significant enrichment 30 31 plasma metabolites female male pigs,...
Chicken is important livestock that serves as a vital food source which remain largely affected by heat stress. Therefore, we performed the transcriptome analysis to help understand mechanisms of stress response in chickens.

Subsequently, RNA-seq was identify DEGs false discovery rate < 0.05 fold change ≥ 1.5. physiological parameters, observed average daily gain...
Amygdalin contents of the seeds, endocarps, and mesocarps from three peach cultivars (i.e., Stone Peach, Hikawa Hakuho, Bakhyang) were measured at stages fruit development (stone-hardening, enlargement, ripening). The samples dried defatted with a Soxhlet apparatus, reflux extracted methanol, analyzed using reverse phase high-performance liquid chromatography. During all stages, amygdalin in seeds higher than those endocarps mesocarps. Peach comparatively Hakuho Bakhyang (P<0.05). Further,...

All PCGs...
Transcriptome expression reflects genetic response in diverse conditions. In this study, RNA sequencing was utilized to profile multiple tissues such as liver, breast, caecum, and gizzard of Korean commercial chicken raised Korea Kyrgyzstan. We analyzed ten samples per tissue from each location identify candidate genes which are involved the adaptation At false discovery rate (FDR) < 0.05 fold change (FC) > 2, we found 315, 196, 167 198 cecum, respectively differentially expressed between...
In this study, the fermentation and quality characteristics of Greek-style yogurt supplemented with stevia leaf extract during storage were examined. Stevia was extracted from dried leaves hot water 70% ethanol. The pH decreased significantly in all samples over time (p<0.05). particular, sharpest decrease detected group which added. Acidity increased Lactic acid bacteria counts up to 9 h after start fermentation, but 12 h. sugar content time, there no major differences between samples....
The mitogenome of Phyllidiopsis krempfi has been determined for the first time. assembled was 14,970 bp in length, including 13 protein-coding genes, 22 transfer RNA, and 2 ribosomal RNA genes. gene content order were identical with those other Phyllidiid species. molecular taxonomic position P. clustered genus Phyllodiopsis clade is closely related Phyllidia. provides significant DNA data further identification phylogenetic analysis within Phyllidiid.
A new cirratulid species, Timareteposteriasp. n., is described from the intertidal habitats of eastern coast South Korea. The species closely related to Timareteluxuriosa (Moore, 1904) southern California based on morphological similarity branchial and tentacular finalents noto- neuropodial spines. However, T.posteriasp. n. differs latter following characteristics: 1) evenly divided peristomium into three annulations; 2) 2-4 spines originating in posterior chaetigers alternated by a few...
The aim was to investigate the effect of reducing odorous and complex odor released during decomposition food wastes using effective microorganism (EM) as a function time at 20℃ 35℃.The variation total microbial counts dominant species in EM leachate produced also observed.In general, cumulative concentration sulfur compounds (H2S, CH3SH) increased with increasing elapsed time.The nitrogen (NH3, trimethyl amine), however, not observed all samples.The addition resulted reduction odor, spite...
Objectives: This study is designed to investigate the effects of Banhahubak-Tang Extract (BHTe) on stress. Methos: BHTe was fed ICR male mice (<TEX>$20{\pm}2g$</TEX>) orally with dose 100 mg/kg/day for five days. Mice were then exposed sociopsychological stress by observing foot shock stressed one hour days while restrained. Results: 1) The BHTe-administered group showed a tendency decreasing serum corticosterone secretion compared control group. 2) an increase in noradrenalin secretions...
