A Case of H. pylori-associated Granulomatous Gastritis with Hypertrophic Gastropathy
( Sang Beom Kang ),( Soon Woo Nam ),( Dong Soo Lee ),( Yeon Soo Kim ),( Hye Kyung Lee ),( Jong Ok Kim ),( Seung Woo Lee ) The Editorial Office of Gut and Liver 2009 Gut and Liver Vol.3 No.2
A 46-year-old man had chronic granulomatous gastritis characterized by giant gastric folds with noncaseating epithelioid granulomas including giant cells in the corpus. No definite etiologic factors were detected. Histology and the rapid urease test indicated that H. pylori was present in both the antrum and corpus. The granulomatous gastritis with giant gastric folds improved after H. pylori eradication. This case suggests an association between isolated granulomatous gastritis and H. pylori infection.

The local heat transfer and total pressure drops of developed turbulent flows in the ribbed rectangular convergent/divergent channels with Λ/V-shaped ribs have been investigated experimentally. The channels have the exit hydraulic diameter (Dho) to inlet hydraulic diameter (Dhi) ratios of 0.67 for convergence and 1.49 for divergence, respectively. The Λ/V-shaped ribs with three different flow attack angles of 30°, 45°, and 60° are manufactured with a fixed rib height (e) of 10 mm and the ratio of rib spacing (S) to height (e) of 10 on the walls. Thermal performances of the ribbed rectangular convergent/divergent channels are compared with the smooth straight tube under identical pumping power. The results show that the flow attack angle of 45° with Λ-shaped rib has the greatest thermal performance at all the Reynolds numbers studied in the convergent channel; whereas, the flow attack angle of 60o with V-shaped rib has the greatest thermal performance over Reynolds number of 30,000 in the divergent channel.

Dysphagia following anterior cervical spine surgery (ACSS) poses a significant clinical challenge, with recurrent laryngeal nerve (RLN) injury emerging as a potential contributor. This case report describes the case of a 55-year-old male who underwent ACSS and subsequently developed dysphagia and hoarseness due to left RLN damage. Employing videofluoroscopic swallowing study (VFSS)-guided balloon dilatation on postoperative day 12, we observed a notable improvement in the opening of the upper esophageal sphincter (UES), as validated by a follow-up VFSS. The patient successfully transitioned from total parenteral nutrition to oral intake, demonstrating the clinical significance of the intervention. Although promising, long-term follow-up studies are warranted to assess the sustained efficacy of VFSS-guided balloon dilatation and the potential recurrence of dysphagia. Safety considerations and protocol variations merit further investigation, emphasizing the need for collaborative multicenter studies. In conclusion, VFSS-guided balloon dilatation is a potentially effective treatment for post-ACSS dysphagia associated with UES dysfunction caused by RLN injury.
HIGH RESOLUTION OPTICAL SPECTRA OF HBC 722 AFTER OUTBURST
Lee, Jeong-Eun,Kang, Won-seok,Lee, Sang-Gak,Sung, Hyun-Il,Lee, Byeong-Cheol,Sung, Hwan-kyung,Green, Joel D.,Jeon, Young-Beom The Korean Astronomical Society 2011 Journal of The Korean Astronomical Society Vol.44 No.2
We report the results of our high resolution optical spectroscopic monitoring campaign (${\lambda}$ = 3800 ~ 8800 ${\AA}$, R = 30000 - 45000) of the new FU Orionis-type object HBC 722. We observed HBC 722 with the BOES 1.8-m telescope between November 26 and December 29, 2010, and FU Orionis itself on January 26, 2011. We detect a number of previously unreported high-resolution K I and Ca II lines beyond 7500 ${\AA}$. We resolve the H${\alpha}$ and Ca II line profiles into three velocity components, which we attribute to both disk and outflow. The increased accretion during outburst can heat the disk to produce the relatively narrow absorption feature and launch outflows appearing as high velocity blue and red-shifted broad features.

Lime bordeaux mixture (LBM) and lime sulfur mixture (LSM) are representative environmental friendly organic materials for prevention of insect pests in South Korea. Recently, those have been widely used as an alternative for chemical pesticides in eco-friendly farms. However, South Korea has not established even recommendation of LBM and LSM considering the stability of heavy metals in soil. The aim of this study was to evaluate the accumulation of hazardous heavy metals in soil and plant with long-term application of LBM and LSM. Firstly, we investigated the amount of LBM and LSM used per year in several eco-friendly farms to determine a standard application rate of both materials. The pepper plant was grown on the pot in greenhouse for 14 weeks. Both materials were applied at 0, 1, 3, and 9 times of standard application rates (2.56 and $1.28L\;ha^{-1}$ of LBM and LSM per year, respectively). Dry matter yield of pepper and heavy metals (As, Cd, Cu, Hg, Ni, Pb, and Zn) concentration in soil and pepper plant were measured after 14 weeks. Yield of pepper plant did not significantly chang with up to application rate of 1 times, thereafter it markedly decreased with more than 3 times. With increasing LBM and LSM application, the concentration of Cu and Zn in soil significantly increased. Especially, Zn concentration in pepper significantly increased with increasing application rates of both materials. This might resulted in significant decrease in dry matter yield of pepper. The concentrations of those heavy metals in soil did not exceed safety levels ($150mg\;kg^{-1}$ for Cu and $300mg\;kg^{-1}$ for Zn) established by the Korean Soil Environmental Conservation Act as well as concentration of heavy metals in pepper plant by Korean Ministry of Food and Drug Safety. However, particular attention should be paid for heavy metal safety and crop productivity when using LBM and LSM in the organic farm.

OBJECTIVES: Several studies have found a significant association between the presence of earlobe crease (ELC) and cardiovascular disease (CVD). Brachial-ankle Pulse Wave Velocity (baPWV) is a non-invasive and useful measure of arterial stiffness predicting cardiovascular events and mortality. However, few studies have reported the relationship between ELC and baPWV as a new measure of arterial stiffness. The purpose of this study was to determine whether ELC is related to baPWV in non-diabetic, non-hypertensive, and apparently healthy Korean adults. METHODS: A cross-sectional study was conducted on 573 non-hypertensive, non-diabetic Korean adults aged 20-80 yr. Subjects were stratified into three groups according to gender and menopausal status. baPWV was measured by an automatic waveform analyser. The association between ELC and baPWV was assessed by multiple linear regression analysis after adjusting for conventional cardiovascular disease risk factors including age, gender, blood pressure, lipid profile, and smoking status etc. RESULTS: The overall frequency of ELC was 19.02% and the subjects with ELC showed significantly higher mean baPWV (p<0.0001). Multiple linear regression of subjects revealed that the presence of ELC was independently associated with baPWV (male, p<0.0001; premenopausal female p=0.0162; postmenopausal female p=0.0208). CONCLUSION: ELC had a significant correlation with baPWV, independently controlling for other classical cardiovascular risk factors in adults aged 20 yr or older. ELC is an important surrogate marker of increased arterial stiffness as measured by baPWV in Korean adults. (Epidemiol Health 2009;31:e2009002).

In monsoon climates, persistent shade is a troublesome weather condition with an impact on the growth and yield of corn (Zea mays L.). We imposed 7, 14, 21, and 28 days of consecutive shade (CS) on Gwangpyeongok and P3394 corn hybrids at the beginning of the kernel filling stages. Shade had little impact on leaf area and dry matter accumulation in the stem and leaves. However, dry matter accumulation in the ear was severely reduced by approximately 28% and 53% after 14 and 28 days of CS, respectively. For the components of grain yield, 7 and 14 days of shade did irreparable damage to the number of filled kernels, the kernel number per ear row, and the percent of filled kernels, but did little damage or reversible damage after removal of the shade to the 100-grain weight and the row number per ear. Shade significantly reduced the relative growth rate (RGR) due to a decrease in the net assimilation rate (NAR). These results suggest that source activity limitation by shade during the kernel filling stages leads to the inhibition of sink activity and size. The yield of biomass, ear, and grain logistically declined as the length of CS increased. Probit analysis revealed that the number of days of CS needed to cause 25% and 50% reductions in grain yield were 3.7 and 23.1, respectively. These results suggest that the plant yield loss induced by shade at the beginning of the kernel filling stages is mainly achieved within the first 7 days of consecutive shade.
