  • The study is a pioneering effort to determine the mineral, nutritional, and phytochemical composition and phenolic content and to determine the free radical scavenging activity of Gigantochloa levis (Blanco) Merr, a native bamboo species (locally known as "bolo") in the Philippines. Proximate analysis showed that air-dried G. levis leaves contain 15.8% ash, 22.6% crude protein, 1.2% crude fat, 29.3% crude fiber, and 19.7% total sugar. Phytochemical tests indicated the presence of diterpenes, triterpenes, saponins, phenols, tannins, and flavonoids in both the ethanolic and aqueous leaf extracts, while phytosterols were only detected in the ethanolic extract. Folin-Ciocalteu assay determined the total phenolic content in gallic acid equivalents (GAE) to be $85.86{\pm}3.71$ and $32.32{\pm}1.01mg\;GAE/100g$ dried sample for the ethanolic and aqueous extracts, respectively. The total phenolic content in quercetin equivalents (QE) was $74.44{\pm}3.11$ and $29.43{\pm}0.85mg\;QE/100g$ dried sample for the ethanolic and aqueous extracts, respectively. The radical scavenging activity of the different solvent fractions containing varying concentrations of the extract was determined using the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. The ethyl acetate and 1-butanol fractions were found to have the highest radical scavenging activity. Mineral analysis via Energy Dispersive X-Ray Spectrometry (EDS) of the ash of G. levis leaves showed that Si is the major component, followed by K and Mg. These results point to the potential of G. levis leaves as a source of minerals and bioactive compounds with medicinal value.

  • Although various raw plant materials have been demonstrated to exert anti-obesity effects to a greater or lesser extent in both humans and animals when they are used to supplement the diet, it has not been shown extensively that they influence adipocyte cell differentiation involving lipid metabolic gene expressions. Using a well-established 3T3-L1 preadipocyte differentiation system, we decided to look into molecular and cellular event occurring during adipocyte differentiation when raw plant materials aye included in the process, in an effort to demonstrate the potential use of a screening system to define the functions of traditionally well-known materials. To these ends, the effects of ethanol (EtOH) or EtOH/distilled water (DW) extracts of Wax Gourd were examined using cytochemical and molecular analyses to determine whether components of the extracts modulate adipocyte differentiation of 3T3-Ll preadipocytes in vitro. The cytochemical results demonstrated that EtOH or EtOH/DW extracts did not affect lipid accumulation and cell proliferation, although the degree of lipid accumulation was influenced slightly depending on the extract. EtOH extract was highly effective in apoptotic induction during differentiation of 3T3-Ll preadipocytes (p<0.05). Reverse transcription-polymerase chain reaction (RT-PCR) analysis of lipoprotein lipase (LPL), Uncoupling protein (Ucp) 2, 3 and 4 also showed that while LPL expression was not influenced, Ucp2, 3 and 4 were up regulated in the EtOH extract-treated group and down regulated in the EtOH/DW extract-treated group. These changes in gene expressions suggest that the components in different fractions of Wax Gourd extracts may modulate lipid metabolism by either direct or indirect action. Taking these results together, it was concluded that molecular and cellular analyses of adipocyte differentiation involving lipid metabolic genes should facilitate understanding of cellular events occurring during adipocyte differentiation. Furthermore, the experimental scheme and analytical methods used in this study should provide a screening system for the functional study of raw plant materials in obesity research.

  • Purpose: This study was conducted to survey children's health status and need of customized visiting health care services in one province. Methods: The participants in this study were 237 caregivers of infants and preschoolers. Data were collected at the participant's home or public health center. Results: Many of the children did not receive developmental screening tests or dental examinations. In the beneficiary group, the prenatal checkup rate and children's vaccination rate were lower, and caregivers had more health problems than the other groups. On the assessment of home safety, unsafe conditions were more frequently found in the beneficiary group. The caregivers in the beneficiary group showed lower child rearing confidence than the other groups, and wanted customized visiting health care services most in the areas of developmental screening, regular health check-up and counseling, nutritional supplementation, and oral health care. Conclusion: These results indicate that it is necessary for children and parents in poverty to be provided with professional home visiting interventions for the promotion of child health and prevention of developmental problems and diseases. These findings can be used for developing future customized visiting health care service programs for infants and children in this community area.

  • Background: The aim was to determine the lifestyle behaviors and the practices for early diagnosis of cancer of cancer patients. Materials and Methods: A descriptive cross-sectional design was used for this study. The sample consisted of 222 patients with a diagnosis of cancer (non-random sample method). Ethical permission was obtained of the Non-interventional Research Ethics Committee of our Institution. Values of p<0.05 were accepted as statistically significant. Results: It was observed that 54.4% of the patients had never performed breast self-examination, 60.8% had never had a mammography, and 71.2% had never had a Pap smear. Sixty-six point two percent of patients had never had screening for colon cancer within the past ten years. GIS cancers were higher in smokers and ex-smokers (p=0.005), in drinkers and in ex-drinkers (p=0.000). The breast cancer rate was higher in obese people (p=0.019). Conclusions: The results of this study provide information on the healthy lifestyle behavior of cancer patients before their diagnosis, and their use of early diagnosis practices. The important aspect of this study is to extend cancer patients' period of life after the diagnosis and treatment process, to make them conscious of risky lifestyle and nutritional behavior so that they can maintain a high quality of life, and to start initiatives in this direction that would ensure changes in behavior.

  • The aim of this study was to identify the drinking patterns and needs for nutritional education of male workers. The subjects in this study were 285 male workers in Ulsan City. The average age of the subjects was 41.2 years old, height was 171.8cm, weight was 69.6kg and Body Mass Index(BMI) was $23.6kg/m^2$. The subjects were classified into 3 drinking patterns such as 'normal drinker(ND)', 'excessive drinker(ED)', and 'alcoholic drinker(AD)' diagnosed by NAST (Alcoholism Screening Test of Seoul National Mental Hospital). Each group was 31.6%(ND), 43.2%(ED) and 25.3% (AD). The amount of one time drinking, frequency, kind of alcohol and spending money were significantly different among the groups. 87.8% of ND thought that the self identity of drinking habits was good. But twenty seven percent of AD thought that it was just not bad, one-half of them(51.4%) thought they seemed to have problems and 20.8% of them thought they were serious. 38.9%(AD), 22.8%(ED) and 6.7%(ND) of each group tried to abstain by turn. Reasons of trying to abstain were health problems, disharmony of family and bad influence on the business and job place. The methods of abstaining were to avoid a drinking gathering or to refuse drinking in the party. 70.8% of AD, 59.3% of ED and 40% of ND thought they needed to take an educational program about abstaining. 58.3% of AD, 43.1 % of ED and 31.1 % of ND answered they would join an alcohol program.

  • In post-genome period, the technique for identifying gene expression has been changed to high throughput screening. In the field of molecular nutrition, the need for this technique to clarify molecular function of the specific nutrient is essential. In this study, we have tested the zinc-regulated gene expression in zinc-deficient U937 cells, using cDNA microarray which is the cutting-edge technique to screen large numbers of gene expression simultaneously. The study result can be used for the preliminary gene screening data for clarifying, using monocyte U937 cell line, molecular Zn aspect in atherosclerosis. U937 cells were cultured in Zn-adequate (control, 12 $\mu$M Zn) or Zn-deficient (experimental, 0 $\mu$M Zn) ESMI media during 2 days, respectively. Cells were harvested and RNA was extracted. Total RNA was reverse-transcriptinized and synthesized cDNA probe labeled with Cy-3. fluorescent labeled cDNA probe was applied to microarray slide for hybridization slide, and after then, the slide was scanned using fluorescence scanner. ‘Highly expressed genes’ in Zn-deficient U937 cells, comparing to Zn-adequate group, are mainly about the genes for motility protein, immune system protein, oncogene and tumor suppressor and ‘Less highly expressed genes’ are about the genes for transcription, apoptosis associated protein, cell cycle, and several basic transcription factors. The results of this preliminary study imply the effectiveness of cDNA microarray for expression profiling of a singly nutrient deficiency, specially Zn. Furthur study, using tailored-cDNA array and capillary endothelial cell lines, would be beneficial to clarify molecular Zn function, more in detail.

  • In this study we compared the cognitive function (Mini-Mental State Examination for Dementia Screening: MMSE-DS) and nutrient intake of elderly women with dementia in a long-term care facility (EW-LCF) and a day-time care facility (EW-DCF). This survey was conducted from July 2015 to May 2017 on 73 elderly women with dementia (47 women in LCF and 26 women in DCF) in the city of Incheon. The data obtained from interviews with the subjects and caregivers were analyzed using the SPSS 20.0. The total score of the MMSE-DS and intakes of most nutrients in the EW-LCF were significantly lower compared to the EW-DCF (p<0.05). The nutrient adequacy ratios (NAR) of protein, vitamin A, C, $B_6$, $B_{12}$, thiamin, riboflavin, niacin, folic acid, calcium and phosphorus in the EW-LCF were significantly lower compared to the EW-DCF (p<0.05). However, the indexes of nutritional quality (INQ) of vitamin C, $B_6$, thiamine, niacin, calcium, magnesium, and iron in the EW-LCF were significantly higher compared to the EW-DCF (p<0.05). As a result, the subjects showed an unbalanced and insufficient nutrition intake status regardless of the type of care facility. Most nutrient intakes of the EW-LCF with lower cognitive function were very significantly lower compared to the EW-DCF (p<0.001). Therefore, it is necessary to assess the cognitive function and nutritional status regularly at care facilities for the elderly women suffering with dementia and to provide specialized individual nutritional management.

  • Purpose: The purpose of this study was to investigate the risk of malnutrition and its relationship with depression and perceived health status. Methods: A total number of 154 elderly over 60 years participated in the study through a community elderly center. The risk of malnutrition was measured by NSI (Nutritional Screening Initiative), depression by CES-D, and health status by a self-rated Likert scale. Results: About one fourth (22.7%) of the subjects had a high risk, and 31.2% had a moderate risk of getting malnutrition. Regarding depression, 34.4% (53 elderly) of the subjects had a high risk. Overall health status had a mean of 3.46 within the range of 1 to 5. In relation to demographic factors, female elderly (${\chi}^2=6.68$, p= .04), aged younger than 75 years old (${\chi}^2=8.60$, p= .01), and having co-morbidity (F=9.81, p= .001) were significantly related to a high risk of malnutrition. Having a higher depression score, higher number of co-morbidity, and lower perceived health status were significantly related to a higher risk of becoming malnourished. Conclusion: The elderly's risk of getting malnutrition was significantly related to their depression and perceived health status. With these findings nursing interventions focusing on these factors should be developed in order to improve the elderly's multidimensional well-being.

  • The aim of this research is to improve Korean lettuce varieties in terms of Fusarium wilt, bolting under hot weather and nutritional function applying genomics approaches. To find related gene/molecular markers, we selected 96 lettuce varieties which are popular in domestic fresh vegetable markets. To construct frame works of the genomic approaches, we exploited GBS(Genotyping by Sequencing) and found total 61,407 SNPs from lettuce whole genomes (MAF>0.02). We observed that Three SNPs array per 100kb of lettuce genome. Average LD decay is expected to expand up to 3.9M(million)bp. Thus, we concluded that about 104 SNPs exist within a LD, which is sufficient to use GWAS(Genome-wide Association Study) to explore the useful gene/molecular markers. In addition, we optimized mass screening method to evaluate disease resistance levels against Fusarium wilt and are testing the bolting sensitivity during summer growing season for those lettuce allele mining set.

  • To understand molecular mechanisms of mouse mammary gland involution, clones were isolated by differential screening of a cDNA library. Partial sequences of a clone showed 100% identity to cDNA sequences of mouse lysozyme P gene. Northern analysis was performed to examine expression levels of lysozyme mRNA in mammary gland at several physiological states. Expression of lysozyme gene was induced at involution day 5 compared with lactating stage. High levels of lysozyme mRNA were also detected at virgin tissues. Two types of separate genes, P and M lysozyme, have been known in mouse, and we found that both lysozyme P and M genes were expressed in mammary tissues by reverse transcriptase-polymerase chain reaction. The lysozyme enzyme activity determined by lysoplate assay was also higher in involuted mammary tissues compared with lactating tissues, showing a similar trend to its mRNA levels. Lysozyme is an antimicrobial protein and involved in host defense mechanism. The increase in lysozyme gene expression may help to prevent microbial infection during mammary gland involution at which stage the residual milk in the mammary gland provides good nutritional sources for microbial growth.
