The identify of biomarkers in living tissues is useful to understand the characteristics and functions of the cells. Proteins such as protein gene product 9.5, promyelocytic leukemia zinc finger, NANOG, and stage-specific embryonic antigen-1 have been identified as markers for porcine undifferentiated spermatogonia. In this study, the expression of insulin-like growth factor binding proteins (IGFBPs), a newly discovered porcine spermatogonia marker and pregnancy-associated plasma protein-A (PAPP-A), a protein regulator of IGFBPs, were characterized in 5-day-old porcine testis. To analyze the function of IGFBPs, RT-PCR was performed. IGFBP 2, 3, 4, and 6 were detected in porcine spermatogonia and PAPP-A was detected in basement regions in 5day old porcine seminiferous tubules. PAPP-A was not expressed in spermatogonia, but it was expressed in Sertoli cells. These results suggest that the expression of PAPP-A protein in Sertoli cells may regulate the development and differentiation of testicular cells through the IGF axis in porcine neonatal testis.
Background: Ulcerative colitis (UC) is the large intestine disease that results in chronic inflammation and ulcers in the colon. Rg3-enriched Korean Red Ginseng extract (Rg3-RGE) is known for its pharmacological activities. Persicaria tinctoria (PT) is also used in the treatment of various inflammatory diseases. The aim of this study is to investigate the attenuating effects of Rg3-RGE with PT on oxazolone (OXA)-induced UC in mice. Methods: A total of six groups of mice including control group, OXA (as model group, 1.5%) group, sulfasalazine (75 mg/kg) group, Rg3-RGE (20 mg/kg) group, PT (300 mg/kg) group, and Rg3-RGE (10 mg/kg) with PT (150 mg/kg) group. Data on the colon length, body weight, disease activity index (DAI), histological changes, nitric oxide (NO) assay, Real-time PCR of inflammatory factors, ELISA of inflammatory factors, Western blot, and flow cytometry analysis were obtained. Results: Overall, the combination treatment of Rg3-RGE and PT significantly improved the colon length and body weight and decreased the DAI in mice compared with the treatment with OXA. Additionally, the histological injury was also reduced by the combination treatment. Moreover, the NO production level and inflammatory mediators and cytokines were significantly downregulated in the Rg3-RGE with the PT group compared with the model group. Also, NLR family pyrin domain containing 3 (NLRP3) inflammasome and nuclear factor kappa B (NF-𝛋B) were suppressed in the combination treatment group compared with the OXA group. Furthermore, the number of immune cell subtypes of CD4+ T-helper cells, CD19+ B-cells, and CD4+ and CD25+ regulatory T-cells (Tregs) was improved in the Rg3-RGE with the PT group compared with the OXA group. Conclusion: Overall, the mixture of Rg3-RGE and PT is an effective therapeutic treatment for UC.
Foot-and-mouth disease, one of the most contagious diseases in cloven-hoofed animals, causes significant economic losses. The pathogenesis of foot-and-mouth disease virus (FMDV) infection is known to differ with age of the animals. In this study, we aimed to reveal the difference in immunological response in the initial stage of FMDV infection between piglets and adult pigs. Peripheral blood mononuclear cells (PBMCs) were isolated from 3 piglets (8 weeks old) and 3 pigs (35 weeks old) that were not vaccinated against FMDV. O-type FMDV (2 × 102 median tissue culture infectious dose) was inoculated into porcine PBMCs and the cells were incubated at 37.0℃ under 5% CO2 for various time periods (0, 1, 3, 6, 12, 24, and 48 h). The total RNA was obtained from the FMDV-inoculated PBMCs after each time point, and the virus titer was investigated in these RNA samples. Furthermore, dynamics of mRNA expression of the six tested cytokines (interferon [IFN]-α, IFN-γ, interleukin [IL]-6, IL-8, IL-10, and tumor necrosis factor [TNF]-α) in FMDV-inoculated porcine PBMCs were evaluated by time-series analysis to determine the differences, if any, based on the age of the pigs. The PBMCs of piglets contained the highest quantity of FMDV mRNA at 6 hours post-inoculation (hpi), and the PBMCs of pigs had the highest quantity of FMDV mRNA at 3 hpi. The mean cycle threshold-value in the PBMCs steadily decreased after the peak time point in the piglets and pigs (6 and 3 hpi, respectively). The dynamics of mRNA expression of all cytokines except TNF-α showed age-dependent differences in FMDV-inoculated PBMCs. The mRNA expression of most cytokines was more pronounced in the piglets than in the pigs, implying that the immune response against FMDV showed an age-dependent difference in pigs. In conclusion, within 48 hpi, the 8-week-old piglets responded more rapidly and were more sensitive to FMDV infection than the 35-week-old pigs, which could be associated with the difference in the pathogenesis of FMDV infection among the pigs. These results provide valuable insights into the mechanisms underlying the age-dependent differences in immune response in pigs against FMDV infection.
The purpose of this study is to improve and develop the quality of non-face-to-face classes according to the types of presence by analyzing the effects of teaching presence and learning presence on the learning satisfaction of the non-face-to-face classes that have been suddenly conducted due to COVID-19. For this purpose, a survey on online classes of H University in Gwangju Metropolitan City was conducted to analyze learning satisfaction, teaching presence (learning design, direct promotion), and learning presence (cognitive presence, social presence). The results of the analysis showed that the learning contents of cognitive presence, which is a sub-factor of learning presence, were understood (=.589, p<.001), the direct promotion (=.420, p<.001), and the learning design (=.397, p<.01), which are the sub-factors of teaching presence, were influential in order.This means that the suddenly changed teaching method should have an attitude to improve the intimacy between the instructor and the fellow learners with positive emotional exchange or interaction. The instructor should try to overcome the limitations of time and space through blended learning that is both online and offline for high quality learning design, but the learning medium and learning method considering the physical fatigue of the learner should be developed.

This study investigated the effects of light intensity on growth performance, blood components, eye condition, and carcass characteristics of broiler chickens. Three hundred and fifty-two 1-day-old male chicks were assigned to one of four treatments (four repetitions per treatment, 22 birds per repetition) and reared in a floor pen for 5 weeks. From the second week, chicks were reared under four different levels of light intensity (5, 20, 35, and 50 lx) and the lighting duration was maintained at 18-hours light : 6-hours dark (18L : 6D). The feed intake and body weight were measured weekly. At 35 days of age, 12 birds per treatment were randomly selected for blood sampling, eye measurement, and carcass analysis. There were no significant differences in body weight gain, feed intake, and feed conversion ratio among treatments. Triglyceride levels in the serum were significantly higher in the 5 lx treatment, and creatinine was significantly lower in the 5 lx treatment (p < 0.05). The heterophil : lymphocyte ratios decreased significantly as light intensity increased (p < 0.05); however, other blood cell compositions were not affected by light intensity. Interleukin-6 content was significantly higher in the 5 lx treatment than in other treatments (p < 0.05), but the content of tumor necrosis factor-α was not significantly different among treatments. Serum corticosterone concentration was significantly higher at 5 lx than at 20, 35, and 50 lx (p < 0.05). The corneal diameter was the highest in 5 lx treatment (p < 0.05), and tended to increase as the light intensity decreased. Other eye parameters were not significantly different among treatments, but displayed a tendency to increase as the light intensity decreased. Carcass yield and part yields were not affected by light intensity. Meat quality parameters (pH, color, cooking loss, and water-holding capacity) did not show significant difference among the treatments. The results indicate that a light intensity of 5 lx may increase physiological stress or have a negative effect on broiler welfare, even if the performance and carcass characteristics are not affected. Therefore, a light intensity of 20 lx or above is recommended considering both the growth performance and welfare of broilers.
Objectives : Neuroinflammation is a common pathological mechanism of neurodegenerative diseases, and the development of therapeutic agents is urgently needed. Red ginseng has been known to be good for the immune stimulation in Eastern Asia. Although the immuno-stimulatory activity of red ginseng are already known, the neuro-protective effects of cultivated red ginseng with fermented complex mushroom-cereal mycelium (RGFM) have not been conducted. Thus, in this study, we tried to investigate the anti-neuroinflammatory effect of RGFM water extract on lipopolysaccharide (LPS) stimulated BV2 cells. Methods : BV2 cells were pretreated with RGFM 1 h prior to LPS exposure. To determine the neuro-protective effects of RGFM water extract, we measured the expression of inflammatory mediators including inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2 and nitric oxide (NO) and pro-inflammatory cytokines such as interleukin (IL)-1𝛽, IL-6 and tumor necrosis factor (TNF)-𝛼 in LPS-stimulated BV2 cells. In addition, to find out the regulatory mechanism of RGFM water extract, we assessed the protein levels of mitogen-activated protein kinases (MAPKs) and inhibitory 𝜅B𝛼 (I𝜅B𝛼) by western blotting. Results : In our study, treatment of RGFM reduced the mRNA expression of iNOS and COX-2 and suppressed NO production in LPS-stimulated BV2 cells. Additionally, the secretion of IL-1𝛽 and TNF-𝛼 but not IL-6 was significantly inhibited by RGFM. Furthermore, RGFM water extract inhibited the phosphorylation of c-Jun N-terminal kinase (JNK). Conclusions : Taken together, these findings suggest that RGFM water extract has a protective effect on neuroinflammation through inhibition of JNK.

Objectives : Hwanggeumjakyak-tang (huangqin shaoyao tang, HJT) has been used to treat acute enteritis in traditional oriental medicine. However, there has been a lack of studies regarding the effects of HJT on the inflammatory activities and effector inflammatory disease mechanism about macrophage before is not known. So we examined the effect of HJT water extract on pro-inflammatory mediators in lipopolysaccharide (LPS) - stimulated mouse macrophage, RAW 264.7 cells. Methods : Cells were treated with 2 ug/mL of LPS 1 h prior to the addition of HJT. Cell viability was measured by MTS assay. The production of nitric oxide (NO) was determined by reacting cultured medium with Griess reagent. The expression of cyclooxygenase-2 (COX-2), inducible NO synthase (iNOS) and mitogen-activated protein kinases (MAPKs) was investigated by Western blot, RT-PCR. The content of level of cytokines (prostaglandin (PG) $E_2$, interleukin (IL)-6, IL-12, Tumor necrosis factor-alpha (TNF-${\alpha}$) and monocyte chemoattractant protein-1 (MCP-1)) in media from LPS-stimulated Raw 264.7 cells was analyed by ELISA kit. Results : HJT inhibited the production of NO, $PGE_2$, IL-6 as well as the expressions of iNOS, COX-2 but did not inhibit the production of IL-12, TNF-${\alpha}$, MCP-1 in the murine macrophage, RAW 264.7 cells. HJT also had suppression effects of LPS-induced MAPKs activation Conclusion : These results suggest that HJT has an anti-inflammatory therapeutic potential, which may result from inhibition of MAPK phosphorylation, thereby decreasing the expression of pro-inflammatory genes.
Objectives : ${\beta}$-Asarone (BAS) is an active ingredient in Acori Rhizoma. This study investigated anti-neuroinflammatory and memory ameliorating effects of BAS in systemic lipopolysaccharide (LPS)-treated C57BL/6 mice. Methods : BAS was administered orally at doses of 7.5, 15, and 30 mg/kg for 3 days prior to LPS (3 mg/kg, intraperitoneal) injection. Pro-inflammatory cytokine mRNA, including tumor necrosis factor-${\alpha}$ (TNF-ㅍ), interleukin (IL)-$1{\beta}$ and IL-6, was measured in hippocampus tissue using real-time polymerase chain reaction at 4 h after the LPS injection. An ameliorating effect of 30 mg/kg BAS on learning and memory impairment in the LPS-treated mice was verified using the Morris water maze test. Results : BAS significantly attenuated up-regulation of TNF-${\alpha}$, IL-$1{\beta}$, and IL-6 mRNA in hippocampus tissue of the LPS-treated mice. In acquisition training test, BAS improved learning performance of the LPS-treated mice with a significant decrease of escape latency to the platform. In memory retention test, BAS also ameliorated memory impairment of the LPS-treated mice with a significant increase of swimming time in zones neighboring to the platform, number of target heading, and memory score. Conclusion : The results suggest that inhibition of pro-inflammatory cytokines and neuroinflammation in the hippocampus by BAS could be one of the mechanisms for BAS-mediated ameliorating effect on learning and memory impairment in LPS-treated mice.

Objectives : The aim of this study was to investigate whether the extract of Coptidis Rhizoma inhibits inflammation in chronic cold stress (CCS)-exposed mice or not. Methods : Coptidis Rhizoma extract (CRE) was made by reflux with distilled water. Male ICR mice (7 weeks old) were divided randomly into 5 groups: (1) control, (2) CCS, (3) CCS+CRE 100 mg/kg, (4) CCS+CRE 300 mg/kg, (5) CCS+CRE 1,000 mg/kg groups. Mice were orally administered once a day for 14 days starting from 1 day before CCS. Group (2)-(5) were exposed to CCS conditions that maintained at $4^{\circ}C$ for 2 h once a day for 14 days. The levels of serum cortisol and hypothalamic prostaglandin E1 (PGE1) and PGE2 were measured by enzyme-linked immunosorbent assay kit. The expression levels of several pro-inflammatory factors like heat shock protein 70 (HSP70), c-fos, and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) were measured by western blot analysis in mouse hypothalamus. Results : Oral administration of CRE 1,000 mg/kg significantly suppressed the increase of serum cortisol levels in mice exposed to CCS. CCS-exposed mice had significantly increased the expression of HSP70, c-fos, and NF-kB in hypothalamus, while CRE treatment significantly attenuated the elevation of these pro-inflammatory factors. The ratio of PGE2/PGE1 was also higher in CCS-exposed mice than control group. CRE treatment significantly reduced the increase of PGE2/PGE1 ratio induced by CCS. Conclusion : These findings suggest that Coptidis Rhizoma may work as a potential agent to modulate inflammatory responses under the condition of cold adaptation formed by CCS.

Many studies on pervaporation (PV) for the separation of dilute alcohols as an alternative to conventional energy-intensive technique of distillation have been conducted earlier. The pervaporation transition behavior of ethanol-water mixtures through the PDMS/PSF membrane is important, in order to understand the mechanism of diffusion process. Therefore, in the present work, transient PV behavior for 50 wt% EtOH/H2O mixture at 50℃ was investigated by using 1194 cm2 PDMS/PSF hollow fiber membrane modules. The overall total flux and the separation factor of all the membrane modules increased initially and then gradually decreased with respect to PV time. The initial increase can be attributed to fact that membrane fibers were dry and it took time to dissolve into the membrane surface, but the subsequent decrease is due to the depletion of ethanol concentration in the feed. Therefore, it was confirmed that the ethanol permeation through a PDMS membrane is governed by the solution-diffusion mechanism.
