The purpose of the study is to investigate the relationships between the BMI and food preference. eating behaviors. and nutrition knowledge score among the middle school male and female students. A total of 394 students from 4 different middle school in Seoul were participated in this study. The students were categorized into 3 groups by BMI : under-weight(〈20). ideal(20$\leq$BMI〈25). and overweight($\geq$25) groups. The data on food preference. eating behavior. and nutrition knowledge were collected by a questionnaire. All data were analyzed by means as frequency. percentage. mean and standard deviation. F-test. $\chi$$^2$-test. and correlation analysis. The results obtained are summarized as follows : 1. BMI average of the male students was 21.4 About 45% of the students were in ideal weight group. 40% were in under-weight group. and 15% were in overweight group according to BMI. 2. About 62% of the participants wanted to lose weight : 43% of the male students. and 82% of the female students. And 33% of the students wished to lose more than 7kg of body weight. 3. Preference score for animal protein foods was the highest in overweight group. On the other hand. preference score of vegetables was the highest in under-weight group. 4. All 3 BMI groups eat more foods on dinner compared to lunch or breakfast. Eating amount score of between-meal was highest(eat more) in under-weight group. and the lowest(eat less) in overweight group. But the percentage of students who eat snack at night was the highest in overweight group. 5. Among the eating behavior variables. eating frequency of snack at night and eating speed were significantly different among 3 groups. Overweight group eat snack at night less frequently and eating speed is faster than the other groups(p〈.05). 6. Nutrition knowledge score was the highest in overweight group. but the difference was insignificant. It is shown that about 40% of the participants belong to under-weight group. but 62% wished to lose weights. Parents and teachers should watch out the juvenile students'health. especially whether they try to lose weight or maintain unrealistically low weight.

The purpose of this study was to understand the effects a mother's degree of obesity has on her daughter's obesity index, psychological well-being index, and nutrient intakes. The daughters, as study subjects, were classified into two groups according to their mother's body mass index (BMI): an obese group [BMI>25 kg/m$^2$, mother obesity group (MOG)] and a normal weight group [BMI<25 kg/m$^2$, mother normal weight group (MNG)]. The daughters in MOG showed significantly higher percent ideal body weight values than the daughters in MNG (p<0.001). MOG and MNG had significantly different psychological well-being index scores in terms of being classified into a highly stressed group (p<0.001), potentially stressed group (p<0.05), and healthy group (p<0.001). Intakes of daily energy, protein, fat, thiamin, riboflavin, niacin, phosphorus, and iron were also significantly different (p<0.001) between MOG and MNG. In particular, the vitamin A and C intakes of the MNG daughters were significantly higher than those of the MOG daughters (p<0.001). Overall, the results showed that a mother's level of obesity was essentially related to her daughter's obesity index, psychological well-being index score, and nutrient intakes. Therefore, it seems necessary for mothers to maintain an ideal body weight to prevent obesity and diet related problems in their daughters.

The purpose of this study was to analyze the nutritional adequacy of one-dish meals in the middle and high school technology & Home Economics textbooks cooking practice units. Total of 27 technology & Home Economics textbooks(9 books published by 9 different publishers each for grade 7, 9, and 10) were examined. The total number of one-dish meals introduced in the textbooks was 27, remarkably low, and there are only 7 Korean one-dish meals. It was found that most one-dish meals failed to meet 1/3 of daily estimated energy requirement. According to the analysis of energy contribution ratio by carbohydrate, protein, and fats in one-dish meals, only 4 Korean foods, such as Yubuchobab, Bibimbab, Deokguk and Guksujangguk showed ideal energy contribution ratio. Among the foreign foods, there was no one-dish meal with ideal energy contribution ratio. According to the index of nutritional quality(INQ) analysis, there was no such one-dish meal which supply all the essential nutrients in adequate amounts. All one-dish meals introduced in the textbooks contained excessive protein, but almost no vitamin $B_1$ and $B_2$. Ca and Fe, likely insufficient in Korean people, was found to be a nutrient insufficient also in most one-dish meals.

Objectives Fish vitellogenin (VTG) is produced in the female liver during oogenesis through the estradiol cycle and produced in the male liver by endocrine disrupting chemicals (EDCs) such as alkylphenols. In this study, we propose that the VTG concentration in the pale chub could be detected using monoclonal antibodies and polyclonal antibodies against vitellin (Vn) in a VTG enzyme-linked immunosorbent assay (ELISA) system. Methods Monoclonal antibodies and polyclonal antibodies were produced using the Vn extracted from the matured ovum of the ovary. The VTG was extracted from the plasma of the male pale chub. The Vn and VTG were confirmed by measuring the molecular weight of their proteins using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and the specificity of the antibodies was checked through western blotting methods. The assay system was validated with respect to optimal assay concentrations, specificity, recovery, and intra- and inter-assay variations. Results The Vn consisted of two protein bands with apparent molecular weights of 64 and 37 kDa. The SDS-PAGE indicated protein weights of 146 and 77 kDa in the VTG. The assay range was 15.6 ng/mL to 2,000 ng/mL, and the value of the intra- and inter-assay variations were within 10.0% and 14.7%, respectively. The recovery rate was $99.5{\pm}5.5%$. Conclusions A sandwich ELISA was developed that could be used to qualify the VTG of pale chub in screening for EDCs. Pale chub is an ideal species for observing estrogen activity in the environment because of its extensive habitat and extensive food chain. The ELISA developed here would be more favorable than those for other species for determining the effect of long-term food chain accumulation of EDCs in aquatic environments.

Breastfeeding is an unequalled way of providing ideal food for the infants. The benefits of breastfeeding practices to infants and mothers are well documented. However, information on breastfeeding practices and its effect on body mass index (BMI) of mothers are scarce, particularly in Ekiti State of Nigeria. Therefore, the present study is designed to assess breastfeeding practices and its association with BMI of mothers. A descriptive and cross-sectional study was conducted among breastfeeding mothers that attended postnatal clinic of the state specialist hospitals and maternity centers in the study location. The specialist hospital and two-third of the nine maternity centers were purposively selected because of their health facilities and personnel. The mother-child pairs (200 respondents) were randomly selected from the study locations. Information on demographic characteristic, socio-economic parameters, nutritional knowledge of breastfeeding and dietary intakes of mothers were collected using questionnaires. BMI of mothers was determined as described by World Health Organization. Age distribution of mothers was between 25-34 years; and almost half of respondents had good educational background and were engaged in different occupations. The respondent monthly income ranged between = N = 3500 - 26000 ($26.92 - $200); and their dietary intakes varied between starchy and protein-based food. The result also showed that the respondent consumed enough nutrients to meet up the recommended daily allowance for protein, carbohydrate, fat, zinc, magnesium, sodium and phosphorous requirements. The BMI classifications showed that over three-fifth of respondents were normal, while the remaining were underweight (6%) and overweight/obese (26.5%). Also, large proportion of respondents engaged in exclusive breastfeeding and with good knowledge of breastfeeding practices. Statistically, exclusive breastfeeding practices had no correlation between the BMI and frequency of breastfeeding. The study, therefore, concluded that mothers had good knowledge of breastfeeding practice; and that there was no association between breastfeeding practices and BMI.

Background: Persistent human papillomavirus (HPV) infection, especially with high-risk types such as HPV16 and HPV18, has been identified as the primary cause of cervical cancer. E6 and E7 are the major onco-proteins of high-risk HPVs, which are consistently expressed in HPV infected tissues but absent in normal tissues and represent ideal therapeutic targets for immunotherapy of cervical cancer. Materials and Methods: In this study, the optimized fusion gene HPV18 E6E7 (HPV18 ofE6E7) was constructed according to genetic codon usage for human genes. At the same time, for safety future clinical application, a mutant of HPV18 ofE6E7 fusion gene was generated by site-directed mutagenesis at L52G for the E6 protein and C98G for the E7 protein. Results: HPV18-E6E7 mutant (HPV18 ofmE6E7) constructed in this work not only lost the transformation capability for NIH 3T3 cells and tumorigenicity in BALB/c nude mice, but also maintained very good stability and antigenicity. Conclusion: These results suggest that the mutant should undergo further study for application as a safe antigenspecific therapeutic vaccine for HPV18-associated tumors.

Stem cells have self-renewal capacity, long-term viability, and multiline age potential. Adult bone marrow contains mesenchymal stem cells. Bone marrow-derived mesenchymal stem cells (BMSCs) are progenitors of skeletal tissue components and can differentiate into adipocytes, chondrocytes, osteoblasts, and myoblasts in vitro and undergo differentiation in vivo. However, the clinical use of BMSCs has presented problems, including pain, morbidity, and low cell number upon harvest. Recent studies have identified a putative stem cell population within the adipose tissue. Human adipose tissue contains pluripotent stem cells simillar to bone marrow-derived stem cells that can differentiate toward the osteogenic, adipogenic, myogenic, and chondrogenic lineages. Human adipose tissue-derived stem cells (ATSCs) could be proposed as an alternative source of adult bone marrow stem cells, and could be obtained in large quantities, under local anesthesia, with minimal discomfort. Human adipose tissue obtained by liposuction was processed to obtain ATSCs. In this study, we compared the osteogenic differentiation of ATSCs in a specific osteogenic induction medium with that in a non-osteogenic medium. ATSCs were incubated in an osteogenic medium for 28 days to induce osteogenesis respectively. Osteogenic differentiation was assessed by von Kossa and alkaline phosphatase staining. Expression of osteocyte specific bone sialoprotein, osteocalcin, collagen type I and alkaline phosphatase, bone morphogenic protein 2, bone morphogenic protein 6 was confirmed by RT-PCR. ATSCs incubated in the osteogenic medium were stained positively for von Kossa and alkaline phosphatase staining. Expression of osteocyte specific genes was also detected. Since this cell population can be easily identified through fluorescence microscopy, it may be an ideal source of ATSCs for further experiments on stem cell biology and tissue engineering. The present results show that ADSCs have an ability to differentiate into osteoblasts. In the present study, we extend this approach to characterize adipose tissue-derived stem cells.

The purpose of this study was to investigate the food habits, nutrient intake, and disease distribution in the elderly (aged over 65 years). The correlation of diseases with anthropometric measurements and nutrients was investigated. The correlation of blood parameters with anthropometric measurements and nutrient intake was also studied. The results are as follow: 1) Most elderly men (68.6%) and women (81.6%) had more than three diseases. The food habits of the elderly women were worse than those of the men. Their intake of protein, calcium, iron, vitamin A, and vitamin $B_2$ were lower than the RDA for those particular nutrients.2) The incidence of gastritis (51.2%) , fatty liver (46.4%) , and hypertension (45.2%) were the highest among elderly men and women. 3) Anemia was negatively correlated with body weight. Hypercholesterolemia was positively correlated with body fat and negatively correlated with intake of calcium, vitamin A, and vitamin $B_2$ . Hypertension was negatively correlated with alcohol consumption. 4) Blood total cholesterol concentration was positively correlated with percent ideal body weight (% IBW) . Blood hemoglobin level was positively correlated with Body Mass Index (BMI) . Systolic and diastolic blood pressure were positively correlated with % IBW and BMI. Blood cholesterol concentration was negatively correlated with the intake of iron, vitamin A, vitamin $B_2$, and cholesterol, and positively correlated with the consumption of alcohol. Blood hemoglobin level was positively correlated with the intake of total calories, carbohydrates, fat, protein, iron, vitamin $B_2$, phosphorus, cholesterol, salt, and alcohol.

BACKGROUND: Plant expression system for mass production of recombinant proteins has several advantages over other existing expression systems with economical and safety issues. Breast cancer is a cancer originating from breast tissue and comprises almost 25% of all cancers in women world widely. Lewis-Y antigen is difucosylated oligosaccharide and is carried by glycoconjugates at cancer cell surface. In this study, the anti-breast cancer mAb BR55, which recognizes the epitope Lewis-Y, was expressed in the plant expression system. METHODS AND RESULTS: We have developed plant system for production of mAb BR55 with or without KDEL (the ER retention signal). This ER retention signal was attached to C-terminus of protein to help retain the recombinant glycoprotein carrying oligomannose glycans and enhance glycoprotein accumulation. PCR analysis was performed and confirmed the presence of recombinant genes. Western blot validated that the recombinant proteins mAb BR55 with or without KDEL were expressed in transgenic plants, moreover, the expression level of the mAb BR55 with KDEL was higher compared to the mAb BR55 without KDEL. CONCLUSION: These results indicate that KDEL fusion is a good way to produce proteins and plant can be an ideal expression system to obtain proteins and enhance accumulation of proteins.

Prolific females require better nutrition and feeding practice because of larger litter size and the substantial decline in body fat. Life-time pig output will be compromised if body protein and fat are not properly managed. First litter females are especially vulnerable because they can loose ${\geq}15%$ of whole-body protein. Conservation of body protein mass during first lactation minimizes wean to estrus interval and increases second litter size (up to 1.2 pigs). The ability to influence litter-size by amino acid nutrition is a new dimension in our understanding. A P2 fat depth below 12 mm at farrow and below 10 mm at wean compromised wean to estrus interval (>2 d) and next litter size (0.5 to 1.5 pigs) in sows. It is now clear that a 'modest' excess of feed during the first 72 h of pregnancy decreases embryo viability so that the potential for an increased litter size at birth is not realized. The capacity for milk production by prolific young sows is 25% higher than the standard used previously (NRC, 1988). First litter females averaged 9.82 kg milk/d for a 21 d lactation. Second and third litter counterparts averaged 10.35 kg/d. Milk production was 95% of peak by 10 d of lactation and sows were in greatest negative energy and lysine balance during the first 6 d. Nearly 45% of the total loss in body protein occurred within the first 6 d, but this could reduced to 30-35% by using a more aggressive feeding strategy after parturition. There appear to be 2 phases in lactation for lysine need (d 2-12 vs 12-21). Feeding to the higher level alleviates the second litter size decline. The lysine requirement for lactation can be predicted with accuracy, but we are not able to predict the second limiting amino acid. Mammary uptake of valine relative to lysine and recent work with practical diets suggest that the recent NRC (1998) pattern is realistic and that threonine and valine could be co-limiting for corn-soy diets for prolific sows nursing 10-11 pigs. Empirical studies are needed to refine the ideal pattern so that synthetic lysine can be used with more confidence. Milk fat output for the elite sow is extraordinary and poses an unnecessarily high energetic cost. Methods that reduce mammary fat synthesis will benefit the sow and may enhance piglet growth.
