Vegetable consumption is associated with health benefits. Recently, the interest in these food groups has grown among due to the identification of new compound in their chemical composition. Most of the vegetables are cooked by blanching, boiling, steaming, microwaving before consumed. These cooking processes may change not only food physical characteristics but also chemical composition. The present study was undertaken to investigate the effect of different cooking methods on phytochemical content and antioxidant capacity in Ipomoea batatas (L.) Lam stem. The result of study, Total polyphenol of phytochemical in Ipomoea batatas (L.) Lam stem was 6.88-12.65 mg GAE/100 g and flavonoid was 3.16-10.46 mg CE/100 g. Compared with the raw of Ipomoea batatas (L.) Lam stem, all cooking methods were found to significant correlations between the antioxidant activity assessed by ABTS, DPPH and polyphenol(p<0.05). These results can be provide the basic data how to prevent lose of nutrition in Ipomoea batatas (L.) Lam stem when cooking.

Objective: The pathology of post-traumatic stress disorder (PTSD) is associated with changes in brain structure and function, especially in the amygdala, medial prefrontal cortex, hippocampus, and insula. Survivors of tragic accidents often experience psychological stress and develop post-traumatic stress symptoms (PTSS), regardless of the diagnosis of PTSD. This study aimed to evaluate electroencephalographic changes according to PTSS in victims of a single traumatic event. Methods: This study enrolled 60 survivors of the Sewol ferry disaster that occurred in 2014 from Danwon High School and collected electroencephalographic data through 19 channels twice for each person in 2014 and 2015 (mean 451.88 [standard deviation 25.77] days of follow-up). PTSS was assessed using the PTSD Checklist-Civilian Version (PCL-C) and the participants were divided into two groups according to the differences in PCL-C scores between 2014 and 2015. Electroencephalographic data were converted to three-dimensional data to perform low-resolution electrical tomographic analysis. Results: Significant electroencephalographic changes over time were observed. The group of participants with worsened PCL-C score showed an increased change of delta slow waves in Brodmann areas 13 and 44, with the largest difference in the insula region, compared to those with improved PCL-C scores. Conclusion: Our findings suggests that the electrophysiological changes in the insula are associated with PTSS changes.
Effect of γ - Irradiation on the Physicochemical Properties of Zein Films
Sehee Lee,Myoungsuk Lee,Kyung Bin Song 한국식품영양과학회 2003 Preventive Nutrition and Food Science Vol.8 No.4
To elucidate the effect of gamma-irradiation on the physicochemical properties of zein films, the molecular and mechanical properties of the films were examined after irradiation at various irradiation doses. Gamma-irradiation of zein solutions caused the disruption of the ordered structure of the zein molecules, as well as degradation, cross-linking, and aggregation of the polypeptide chains based on an SDS-PAGE study. Gamma-irradiation increased the solubility of zein and decreased the viscosity due to cleavage of the polypeptide chains. Protein solubility of the zein films in urea/2-mercaptoethanol also increased with increasing irradiation doses. Alterations of the zein molecules by irradiation decreased water vapor permeability by 12% and increased the elongation of zein films. However, mean tensile strength of the zein films was decreased by gamma-irradiation treatment. Measurement of Hunter color values indicated that irradiation caused a destructive effect on yellow pigments, resulting in a significant decrease in Hunter b values. The microstructure as observed by scanning electron microscopy showed that irradiated zein film had a smoother and glossier surface than the non-irradiated films.
Gastroesophageal Reflux Disease in Type 2 Diabetes Mellitus With or Without Peripheral Neuropathy
( Sehe Dong Lee ),( Bo Ra Keum ),( Hoon Jai Chun ),( Young Tae Bak ) 대한소화기기능성질환·운동학회(구 대한소화관운동학회) 2011 Journal of Neurogastroenterology and Motility (JNM Vol.17 No.3
Background/Aims Patients with type II diabetes mellitus (DM) were known to have higher prevalence of gastroesophageal reflux disease (GERD). Recent studies have shown that neuropathy has positive role on the development of GERD in type II DM, although its pathogenesis has not been fully understood yet. The aim of this study was to investigate whether neuropathy really contribute to the development of GERD and typical GERD symptoms in patients with type II DM in Korea. Methods One hundred and nineteen patients with type II DM who had given informed consents were enrolled. All patients underwent electromyography to check the presence of peripheral neuropathy, face-to-face interview to evaluate their typical GERD symptoms and esophagogastroduodenoscopy to look for the presence of erosive esophagitis. Ninety-five patients were finally included for this study and they were divided according to the presence or absence of the peripheral neuropathy. Results The mean age of 95 patients was 59.3 ± 9.1 years and the mean disease duration of DM was 9.3 ± 5.9 years. Typical GERD symptoms were similarly found in both groups with and without peripheral neuropathy (23.6% vs 22.8%, P = 0.921). Erosive esophagitis was more prevalent in patients with neuropathy than in those without neuropathy (31.5% vs 10.5%, P = 0.022). Conclusions In patients with type II DM, peripheral neuropathy is an independent risk factor for the erosive esophagitis. However, peripheral neuropathy did not contribute to the presence of the typical GERD symptoms.
