As sloped farmland is subject to runoff and soil erosion and consequently require appropriate vegetative coverage to conserve soil and water, a field study was carried out to evaluate the impact of crop canopy coverage on soil loss and runoff from the experimental plot with three different textural types (clay loam, loam, and sandy loam). The runoff and soil loss were examined at lysimeters with 15% slope, 5 m in length, and 2 m in width for five months from May to September 2009 in Suwon (37° 16" 42.67" N, 126° 59" 0.11" E). Red pepper (Capsicum annum L. cv. Daechon) seedlings were transplanted on three different dates, May 4 (RP1), 15 (RP2), and 25 (RP3) to check vegetation coverage. During the experimental period, the vegetation coverage and plant height were measured at 7 day-intervals and then the "canopy cover subfactor" (an inverse of vegetation cover) was subsequently calculated. After each rainfall ceased, the amounts of soil loss and runoff were measured from each plot. Under rainfall events >100 mm, both soil loss and runoff ratio increased with increasing canopy cover subfactor (R²=0.35, p<0.01, R²=0.09, p<0.1), indicating that as vegetation cover increases, the amount of soil loss and runoff reduces. However, the soil loss and runoff were depending on the soil texture and rainfall intensity (i. e., EI30). The red pepper canopy cover subfactor was more highly correlated with soil loss in clay loam (R²=0.83, p<0.001) than in sandy loam (R²=0.48, p<0.05) and loam (R²=0.43, p<0.1) plots. However, the runoff ratio was effectively mitigated by the canopy coverage under the rainfall only with EI30<1000 MJ mm ha<SUP>-1</SUP> hr<SUP>-1</SUP> (R²=0.34, p<0.05). Therefore, this result suggested that soil loss from the red pepper field could be reduced by adjusting seedling transplanting dates, but it was also affected by the various soil textures and EI30.

Effects of β-Glucan on the Release of Nitric Oxide by Macrophages Stimulated with Lipopolysaccharide

Choi, E.Y.,Lee, S.S.,Hyeon, J.Y.,Choe, S.H.,Keum, B.R.,Lim, J.M.,Park, D.C.,Choi, I.S.,Cho, K.K. Asian Australasian Association of Animal Productio 2016 Animal Bioscience Vol.29 No.11

This research analyzed the effect of ${\beta}$-glucan that is expected to alleviate the production of the inflammatory mediator in macrophagocytes, which are processed by the lipopolysaccharide (LPS) of Escherichia. The incubated layer was used for a nitric oxide (NO) analysis. The DNA-binding activation of the small unit of nuclear factor-${\kappa}B$ was measured using the enzyme-linked immunosorbent assay-based kit. In the RAW264.7 cells that were vitalized by Escherichia coli (E. coli) LPS, the ${\beta}$-glucan inhibited both the combatant and rendering phases of the inducible NO synthase (iNOS)-derived NO. ${\beta}$-Glucan increased the expression of the heme oxygenase-1 (HO-1) in the cells that were stimulated by E. coli LPS, and the HO-1 activation was inhibited by the tin protoporphyrin IX (SnPP). This shows that the NO production induced by LPS is related to the inhibition effect of ${\beta}$-glucan. The phosphorylation of c-Jun N-terminal kinases (JNK) and the p38 induced by the LPS were not influenced by the ${\beta}$-glucan, and the inhibitory ${\kappa}B-{\alpha}$ ($I{\kappa}B-{\alpha}$) decomposition was not influenced either. Instead, ${\beta}$-glucan remarkably inhibited the phosphorylation of the signal transducer and activator of transcription-1 (STAT1) that was induced by the E. coli LPS. Overall, the ${\beta}$-glucan inhibited the production of NO in macrophagocytes that was vitalized by the E. coli LPS through the HO-1 induction and the STAT1 pathways inhibition in this research. As the host immune response control by ${\beta}$-glucan weakens the progress of the inflammatory disease, ${\beta}$-glucan can be used as an effective immunomodulator.

Purpose: Precedent studies about the relationship between trauma and other variables was focused on children and middle aged women. This study however, aims to study the female college student population who are exposed to depression and low self-esteem from traumatic events of childhood and adolescence Methods: Using a descriptive correlation study design, 205 female college students attending female colleges were recruited. The instruments Post-traumatic Diagnostic Scale by Jacoz&Perry(1997), Self-esteem Scale by Rosenberg(1979), Family Support &Conflict Scale by Kim, and Depression Scale by Radloff(1977) were used. The questionnaires were distributed with Google Survey online. The data w re analyzed by average, standard deviation, percentage, and t-test using the SPSS/WIN 21.0 program. Results: The degree of trauma and self-esteem, family support and conflict showed negative correlation, and the degree of trauma and depression showed positive correlation. In other words, female college students with higher trauma tend to have lower self-esteem, more cognizance of family conflict, less feeling of family support, and more depression. Conclusion: This study is different in that it analyzes correlation between the degree of trauma and other variables, not the absence or frequency of trauma. This study is also meaningful as it consider the psychological changes from traumatic experience and provides the basic data for the prevention and therapeutic intervention in clinical field.

Purpose: The purpose of this study was to identify the effects of self-efficacy, and social support on climacteric coping, of middle-aged women in rural area. Method: The study subjects included 172 women aged 40-65 years based on eup, myoen, and ri areas of Incheon, Ulsan, Gyeonggi-do, and Gyeongsangbuk-do. The instruments used in this survey were the &self-efficacy scale& (SES) developed by Sherer, M., Maddux et al(1982), which was translated by Hong(1995), &the social support scale& developed by Park(1985), and &the adaptation of the symptoms of menopausal& developed by Bae(1999) and modified by Choi(2008). The data were collected by the face to face interview with a questionnaire from December 9th to 31st 2016. Data was statistically analyzed using t-test, one-way ANOVA, Pearson correlation coefficient and linear regression. Results: There were statistically no significant difference in climacteric coping and self-efficacy. The climacteric coping were significantly associated with informational social support. Also there were statistically significant difference in self-efficacy and social support. Conclusion: These finding suggest the need to develop nursing intervention to improve climacteric coping of middle-aged women in rural area. To improve the climacteric coping of middle-aged women in rural area, factors such as status of education and living with or without husband should be considered.

von Hippel–Lindau protein promotes Skp2 destabilization on DNA damage

Roe, J-S,Kim, H-R,Hwang, I-Y,Cho, E-J,Youn, H-D Macmillan Publishers Limited 2011 Oncogene Vol.30 No.28

Germline mutations in the von Hippel–Lindau (VHL) tumor suppressor gene cause VHL disease, a rare and autosomal-dominant genetic syndrome. Because VHL protein (pVHL) is the master regulator of hypoxia-inducible factor alpha (HIFα), the most prominent feature of VHL disease is the deregulation of HIFα proteins. However, the precise mechanism by which the loss of pVHL function contributes to tumorigenesis is not fully understood. Here, we show that pVHL destabilizes the F-box protein Skp2, a chief component of Skp, Cullin, F-box-containing complex that promotes DNA synthesis in the S phase. The β-domain of pVHL interacts with Skp2, stimulating proteasome-dependent Skp2 degradation, but the destabilization of Skp2 does not depend on the E3 ubiquitin ligase activity of pVHL. Notably, the generation of DNA damage induces Skp2 degradation, which is attenuated by the suppression of endogenous pVHL expression. One possible mechanism of pVHL-dependent Skp2 degradation entails the antagonizing of Akt-mediated Skp2 phosphorylation, which maintains Skp2 stability. Reintroduction of VHL into VHL-null renal cell carcinoma (RCC) cells decreased Skp2 levels and restored DNA damage-dependent Skp2 degradation. These results identify the tumor suppressor function of pVHL in delaying the S-phase progression to inhibit cell proliferation on DNA damage. Clinically, this report explains as to why Skp2 accumulates abnormally in RCC tissues.

Rapid expression of RASD1 is regulated by estrogen receptor-dependent intracellular signaling pathway in the mouse uterus

Kim, H.R.,Cho, K.S.,Kim, E.,Lee, O.H.,Yoon, H.,Lee, S.,Moon, S.,Park, M.,Hong, K.,Na, Y.,Shin, J.E.,Kwon, H.,Song, H.,Choi, D.H.,Choi, Y. North-Holland 2017 Molecular and cellular endocrinology Vol.446 No.-

<P>Dexamethasone-induced RAS-related protein 1 (RASD1) is a signaling protein that is involved in various cellular processes. In a previous study, we found that RASD1 expression was down-regulated in the uterine endometrium of repeated implantation failure patients. The study aim was to determine whether RASD1 is expressed in the endometrium of mouse uterus and how it is regulated by steroid hormones during the estrous cycle. In this study, we investigated RASD1 expression and regulation in an ovariectomized female mouse model. Rasdl mRNA was highly expressed in mouse reproductive tissues, including the uterus. Rasdl expression was detected exclusively in the endometrial epithelium at the proestrus stage of the estrous cycle. Rasd1 expression in uteri increased with administration of estradiol, but not progesterone. Its expression was rapidly induced within 2 h after E2 treatment. Pretreatment with ICI 182,780, an estrogen receptor antagonist, reduced RASD1 protein expression. In addition, we identified that rapid expression of Rasd1 was mediated by the estrogen intracellular signaling including both p38-mitogen-activated protein kinase and the extracellular signal-regulated kinase. These findings suggest that RASD1 acts as a novel signaling molecule and plays an important role in regulating dynamic uterine remodeling during the estrous cycle in the uterus.

health promotion behavior of middle aged men and the relationship among the above factors. Methods: Subjects of the research were 325 middle aged men in Korea. The questionnaires were composed of general characteristics, Health Self Rating Scale, FACES-Ⅲ : Family Adaptability & Cohesion Evaluation Scale Ⅲ, Health Promoting Lifestyle Profile. Data were statistically analyzed by t-test, ANOVA, Scheffe test and Pearson’s correlation. Results: Middle aged men whose perceived economic status are low show lower perceived health status than moderate and high (F=3.364, p=.010). Health promotion behavior in the age 40-44 shows lower level than 60-64 (F=2.984, p=.019). Middle aged men who have Economically dependent adult in the first child show higher level in health promotion behavior than who have Middle & High school student in the first child (F=2.468, p=.045). In the middle aged men, perceived health status and family cohesion show positive correlation (r=.341, p<.01). Perceived health status and health promotion behavior show positive correlation (r=.500, p<.01). Family cohesion and health promotion behavior show posotive correlation (r=.564, p<.01). Conclusions: We analyzed influencing factor and a relationship between perceived health status, family cohesion and health promotion behavior. Accordingly, we can think of applying nursing interventions to the middle aged men considering the general characteristics. Also we can think of applying nursing interventions and educations to help them evaluate their perceived health status and include the support of family members for the health promotion behavior.
