This study was carried out to investigate the effects of added emulsifier and enzyme on the quality characteristics of Seolgiddeok with black rice powder, green tea powder, Lentines edodes powder, pumpkin powder during storage. Samlpes were divided into two groups, the emulsifier-enzyme added group and the control, and stored fur 4 days at 2$0^{\circ}C$. Moisture content was measured by the air oven method; the Hunter's cole. values by Lightness (L), redness (a), yellowness (b) value; the degree of gelatinization by the enzyme digestion method, and expressed as glucose content by Somogi-Nelson method. The degree of retrogradation was calculated as the retrogradation rate using the degree of gelatinization value, and total cell and mold counts were also measured. Texture and sensory characteristics were also investigated. The results are as follows: The emulsifier-enzyme group was significantly different from the control from each examination and the retrogradation of pumpkin Seolgiddeok with emulsifier-enzyme was delayed the most among samples tested.

The incidence rate of breast cancer in developed countries is almost three-fold higher than in developing countries. Iran has had one of the lowest incidence rates for breast cancer in the world, but during the recent decades a marked increase has been seen. The purpose of this study was to investigate some established risk factors of breast cancer in Iranian women. A study of 11,850 women participating in abreast screening program was conducted. The 197 women diagnosed with breast cancer and 11,653 healthy women were compared. Logistic regression was performed to investigate associations of reproductive and anthropometric factors with breast cancer risk. Family history of breast cancer (OR=1.94, 95%CI=1.35-2.78), occupation (OR= 1.65,95%CI=1.20-2.25), education level (OR=0.50,95%CI=0.28-0.91), parity (OR=0.27, 95%CI=0.12-0.59), menopausal status (OR=3.15, 95%CI=2.35-4.21), age at menarche (OR=0.33, 95%CI=0.15-0.70), and age at the first pregnancy (OR=4.10, 95%CI=1.13-14.77) were related to the risk of breast cancer. Decrease in parity may to some extent explain the rising trend of incidence of breast cancer incidence in Iranian women.

Purpose: The purpose of this study was to examine body composition and dietary self-efficacy in nursing students. Methods: The study was a descriptive, correlational study with a convenience sample of 197 female nursing students. This study was conducted from April 1st to May 31th in 2015. SPSS 21.0 program was used for data analysis. Results: The average of body protein was $7.90{\pm}1.17kg$ and normal range was 33%. A BMI's average was $21.02{\pm}2.94kg/m^2$ and 62.9 fell into standard range. The average of dietary self-efficacy of subjects was $3.42{\pm}0.53$. The subjects performed intense physical activities during three or more days had higher body protein (F=5.89, p=.003), body minerals (F=6.15, p=.003) and body-efficacy (F=4.13, p=.017) but remarkably lower body fat (F=4.04, p=.019). There is no noticeable correlation of body composition with dietary self-efficacy. However, it is obvious that each category of body composition had a significant positive correlation. Conclusion: This study demonstrated that students who were inclined to overeat had higher body protein, body minerals, body fat, and BMI. Students performed intense physical activities had high body protein, body minerals, and dietary self-efficacy, whereas they had low body fat. Each entry between the body composition had a significant positive correlation.

Background: Hemidiaphragmatic paralysis, a frequent complication of the brachial plexus block performed above the clavicle, is rarely associated with an infraclavicular approach. The costoclavicular brachial plexus block is emerging as a promising infraclavicular approach. However, it may increase the risk of hemidiaphragmatic paralysis because the proximity to the phrenic nerve is greater than in the classical infraclavicular approach. Methods: This retrospective analysis compared the incidence of hemidiaphragmatic paralysis in patients undergoing costoclavicular and supraclavicular brachial plexus blocks. Of 315 patients who underwent brachial plexus block performed by a single anesthesiologist, 118 underwent costoclavicular, and 197 underwent supraclavicular brachial plexus block. Propensity score matching selected 118 pairs of patients. The primary outcome was the incidence of hemidiaphragmatic paralysis, defined as a postoperative elevation of the hemidiaphragm > 20 mm. Factors affecting the incidence of hemidiaphragmatic paralysis were also evaluated. Results: Hemidiaphragmatic paralysis was observed in three patients (2.5%) who underwent costoclavicular and 47 (39.8%) who underwent supraclavicular brachial plexus blocks (P < 0.001; odds ratio, 0.04; 95% confidence interval, 0.01-0.13). Both the brachial plexus block approach and the injected volume of local anesthetic were significantly associated with hemidiaphragmatic paralysis. Conclusions: The incidence of hemidiaphragmatic paralysis is significantly lower with costoclavicular than with supraclavicular brachial plexus block.

Purpose: The aim of this study was to investigate the impact of preoperative low body mass index (BMI) on both the short- and long-term outcomes in patients with gastric cancer. Materials and Methods: A total of 510 patients with gastric cancer were divided into the following 3 groups: low BMI group (${\leq}18.5kg/m^2$, n=51), normal BMI group ($18.6-24.9kg/m^2$, n=308), and high BMI group (${\geq}25.0kg/m^2$, n=151). Results: There were significantly more stage III/IV patients in the low BMI group than in the other groups (P=0.001). Severe postoperative complications were more frequent (P=0.010) and the survival was worse (P<0.001) in the low BMI group. The subgroup analysis indicated that survival was worse in the low BMI group of the stage I/II subgroup (P=0.008). The severe postoperative complication rate was higher in the low BMI group of the stage III/IV subgroup (P=0.001), although the recurrence rate and survival did not differ in the stage III/IV subgroup among all the BMI groups. Low BMI was an independent poor prognostic factor in the stage I/II subgroup (disease-free survival: hazard ratio [HR], 13.521; 95% confidence interval [CI], 1.186-154.197; P=0.036 and overall survival: HR, 5.130; 95% CI, 1.644-16.010; P=0.005), whereas low BMI was an independent risk factor for severe postoperative complications in the stage III/IV subgroup (HR, 17.158; 95% CI, 1.383-212.940; P=0.027). Conclusions: Preoperative low BMI in patients with gastric cancer adversely affects survival among those with stage I/II disease and increases the severe postoperative complication rate among those with stage III/IV disease.

Advanced glycation end products (AGE) have been implicated in the pathogenesis of diabetic complications including nephropathy. However, the role of AGE in the activation of mesangial cells cultured under high glucose has not been elucidated. The effects of aminoguanidine, which prevents formation of AGE and protein cross-linking, on the synthesis of $TGF-{\beta}1$ and fibronectin by rat mesangial cells cultured under high glucose for 2 weeks were examined and compared with the effects of $N^G$-nitro-L-arginine methyl ester (NAME), a selective nitric oxide synthase inhibitor, because aminoguanidine also inhibits the inducible nitric oxide synthase. Culture of mesangial cells in 30 mM (high) glucose for 2 weeks induced 1.5-fold (ELISA) and 1.9-fold (Western blot analysis) increase in AGE in the culture media compared to 5.6 mM (control) glucose. Northern blot analysis revealed 1.5-fold increase in $TGF-{\beta}1$ and 1.7-fold increase in fibronectin mRNA expression in cells cultured under high glucose compared to control glucose. Increases in mRNA expression were followed by increased protein synthesis. Mink lung epithelial cell growth inhibition assay revealed 1.4-fold increase in $TGF-{\beta}1$ protein in high glucose media compared to control. Fibronectin protein also increased 2.1-fold that of control glucose by Western blot analysis. Administration of aminoguanidine suppressed AGE formation in a dose dependent manner and at the same time suppressed $TGF-{\beta}1$ and fibronectin synthesis by mesangial cells cultured in both control and high glucose. In contrast, NAME did not affect high glucose-induced changes. These findings support a role for AGE in high glucose-induced upregulation of $TGF-{\beta}1$ and fibronectin synthesis by mesangial cells.

Pseudomonas fluorescens which is able to utilize malonate as a sole carbon source was found to contain a novel 60 kb plasmid, which encodes the genes for the proteins to assimilate malonate, including malonate decarboxylase and acetyl-CoA synthetase. The evidence is as follows: The Pseudomonas cured with mitomycin C was unable to grow on malonate-medium as well as it lost plasmid. The plasmid isolated from the Pseudomonas could be introduced into E. coli strain JM103 and DH1 by transformation. The transformed E. coli was able to grow on malonate-medium and could transmit its plasmid back to the cured P. fluorescens by conjugation. The existence of the plasmid in the transformed E. coli was confirmed by hybridization with a labeled probe prepared from 12 kb segment of the plasmid. Dot hybridization showed that the copy number of the plasmid in the transformed E. coli is at least 13 times higher than in the wild type P. fluorescens. The two key enzymes, malonate decarboxylase and acetyl-CoA synthetase, were inducible by malonate in the transformed E. coli.

The purpose of this study was twofold: one, to provide basic data to prevent smoking among university students and two, to develop an effective no smoking program for university students. Two hundred and ten 210 university students who smoked were enrolled in the study. Data were collected from September, 1999 to January, 2000 using a questionnaire. The data collected were scored by using mean and standard deviation according to the motivations for smoking, the psychological characteristics and the motivation for not smoking. Each item was analyzed as an independent variable by the t-test and the ANOVA test. The results were as follows: 1. The average score of subjects' smoking motivation and psychologic characteristics was 2.59. 2. The average score of subjects' no smoking was 3.18. 3. With the respect to the general characteristics of subjects' smoking motivation and psychologic characteristics. there were significant difference in allowance for the month (F=6.197, P=.002), smoking reason (F=4.196, P=.003), smoking type(F=2.34, P=.035), father's smoking(F=3.119, P=.027), and smoking of close friend (F=4.430, P=.013). In subjects' no smoking motivation. there were significant difference in age (F=3.469, P=.033) and starting time of smoking(F=2.834, P=.039) 4. There was a significant correlation (r=.190, p=.007) between subjects' smoking motivation, psychologic characteristics and no smoking motivation.

In order to study the prevalence of constipation among female college students in Korean and the effect of yogurt, 3,243 students in Seoul area were surveyed by questionnaires for the status of stool evacuation and 197 students with possible constipation were sampled and fed apple yogurt II from Pasteur dairy Company for 3-weeks period. Students of constipation amounted to a high ratio of 53.4%, which consisted of 13.4% in heavy constipation (1-2 times evacuation per week) and 40.0% in mild constipation(3-4times evacuation per week) during the past one-year period. To 90 of heavy constipation and 107 of mild constipation students were fed 290ml of yogurt every morning for 3-weeks period and examined for the status of stool evacuation by subsequent after 1 weeks, 57.9% after 2 weeks and 60.4% after 3 weeks(p<0.05). The effect of improvement in stool frequency was greater in heavy group than in mild group through the 3-weeks period. The number of students who experienced the disappearance of inconvenience in evacuation after drinking the yogurt was 52.3% after 1 weeks, 72.1% after 2 weeks and 76.1% after 3 weeks. Discomfort such as stomach disorder and mild diarrhea during the drinking period was observed in 24% students and it appeared that a longer drinking period was needed stool frequency was 38.7% after 1 week and 37.6% after 1 month since discontinuing yogurt drinking. The number of students reverted to the previous habit of evacuation after discontinuing was 51.6% after 1 week and 63.5% after 1 month, which were not significantly different between heavy and mild groups(p>0.05).
