Background: While the incidence of non-Hodgkins lymphoma (NHL) has been rising worldwide, the reasons remain undefined. Recent research has focused on effect of red andf processed meat intake as a risk factor, but with inconclusive results. We therefore conducted a meta-analysis of data published to date, to ascertain the overall association between intake and NHL. Materials and Methods: A published literature search was performed through Pubmed, Cochrane Library, Medline, and Science Citation Index Expanded databases for articles published in English. Pooled odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated using random or fixed effects models. Heterogeneity was assessed using Chi-square and I2 statistics. Dissemination bias was evaluated by funnel plot analysis.We performed a formal meta-analysis using summary measures from these studies. Results: In total, 11 published studies were included in the final analysis. The combined analysis revealed that there was significant association between the red meat and NHL risk (OR=1.10, 95%CI: 1.02 to 1.19, p=0.01). Additionally, there was showed significance association between processed red meat and NHL risk (OR=1.17, 95%CI: 1.06 to 1.29, p=0.001). In subgroup analysis, a statistical significant association was noted between diffuse large B-cell lymphoma (DLBCL) (OR=1.20, 95%CI: 1.04 to 2.37, P=0.01) and red meat intake. Conclusions: In this meta-Analysis, there was evidence for association between consumption of red meat, or processed meat and risk of NHL, particularly with the DLBCL subtype in the red meat case.

Objectives: The main purpose of this study was to examine factors contributing the quality of life related to oral heath such as level of oral health knowledge, subjective knowledge on oral health, awareness of oral health and OHIP-14, and furthermore to analyze any relations among these factors. Methods: The questionnaire survey was carried out on a convenience sample of 230 middle school students at the selected middle school in Chungcheongnam-do. T-test and one-way ANOVA and correlation test were conducted over the collected datas using SPSS 12.0(SPSS 12.0 KOR for Windows, SPSS Inc, Chicago, USA). Results: The results of the study are as follows: 1. 6.38 was average score for oral health knowledge and 10.0 was the maximum. Subjective oral health awareness scored of average 2.99 with maximum of 5.0. OHIP-14 corresponded to average 4.30 and maximum 5.0. 2. Different level of oral heath knowledge was resulted from that of education, which means the greater level of oral health knowledge indicated greater awareness of oral health. 3. OHIP-14 was higher for those who lived with their parents than those who in did not(P=0.012). 4. There exhibits a proportional relationship between subjective awareness of oral health and OHIP-14(r=0.297). Conclusion: It was found that subjective awareness of oral health partially influences to OHIP-14. In other words, subjective awareness of oral health has an effect on the quality of life related to oral health. Hence, there needs more effort on oral health education and oral disorder prevention activities in order to improve subjective awareness of oral health.

Polycystic Ovarian Syndrome (PCOS) has now become more common in occurrence in women of reproductive age, particularly in urban and semi-urban population in India. So there is a need to investigate this phenomenon taking into consideration various aspects including possible treatment method to ameliorate/eradicate this syndrome, which has far reaching socio-economic impact and consequences, in view of infertility and irregular menstrual cycles frequently associated with this syndrome. Homeopathy is a branch of traditional alternative medicine which is gaining popularity in India and some other developing countries, as also in some of the developed countries in Europe. With this background scenario, we have made an attempt to treat cases of confirmed PCOS and tried to compare the relative efficacy of two potentized homeopathic drugs, namely, Lycopodium clavatum (Lyco) and Calcarea carbonica (Calc), most frequently used by homeopathic practitioners, selecting different potencies of the drugs, depending on condition/guiding symptom(s) of the patients. While the main focus was pointed on total/partial removal of cysts, data pertaining to different PCOS associated symptoms were also compared for the sake of learning if the two drugs had differential effects on these symptoms also. The study parameters in this investigation included: regularity/irregularity of menstrual cycle, presence/absence of acne, hirsutism, male type alopecia, acanthosis nigricans, body/mass index (BMI) and waist-hip ratio. Overall results provided clear evidences that both these homeopathic drugs had great ameliorating effects on PCOS, although each drug had a little different effect in respect of the individual parameters of this study.

We have investigated the in vitro cytotoxic effect of liposome-encapsulated N-(phospho-nacetyl)-L-aspartic acid (PALA) against C-26 murine colon cancer cells, and have compared it in this regard to free PALA. Three different PALA-containing liposomal formulations using distearoylphosphatidylcholine (DSPC), distearoylphosphatidylglycerol (DSPG), and polyethyle-neglycol-derivatized distearoylphosphatidylethanolamine (PEG-DSPE) were made and their cytotoxicity was measured. In 72 hr continuous exposure experiment with C-26 cells, the 50% growth inhibitory concentration ($IC_50$) of DSPG-PALA liposome formulation was $0.09\mu\$, which showed about 65-fold more potent than unencapsulated free PALA ($5.1\mu\$). Similar degree of increase in cytotoxicity was also observed in 1 hr exposure experiment. However the $IC_50$ of PEG-DSPE-PALA liposome and DSPC-PALA liposome were $10.7\mu\$and $11.8\mu\$respectively, which showed slightly less potent than unencapsulated free PALA. Physical characteristics of PALA-liposomes, such as the size and drug:lipid ratio were also determined. In conclusion, negatively-charged DSPG-PALA liposome showed the highest cytotoxic effect among tested on the C-26 cells in vitro.

The purpose of this study was to measure the effects of service quality mediating the linkage among food and beverage price, restaurant image and value. A total of 273 questionnaires were completed. MANOVA, ANOVA and ANCOVA were used to measure the mediating effect of service quality on the relationships among food and beverage price, restaurant image, and value. The effects of food and beverage price and restaurant image on service quality and value were statistically significant. As expected, when food and beverage price and service quality were regressed on the value, the service quality was significant and the effect of the food and beverage price was reduced. Moreover, when restaurant image and service quality were regressed on the value, the restaurant image and service quality had a significant effects on value. The results demonstrated that service quality played a mediating role in the relationship between food and beverage price and value, and between restaurant image and value.

The Purpose of this study is to develop and test a nursing model which can be applied to prediction of the quality of life for the patient receiving hemodialysis. A hypothetical model was constructed on Johns & Meleis's empowerment model framework which has 3 contsructs(stress, resource, empowerment). 6 Factors(perceived stress, self-esteem as personal resource, perceived social support as social resource, perceived fertigue, perceived health status & self efficacy as empowerment) were selected to pre dict the quality of life of receiving hemodialysis patients. 4 Factors(self-esteem, perceived social support, perceived health status & self efficacy) had direct effects on the quality of life significantly. Self-esteem had indirect effect on the quality of life via perceived heath status significantly. Perceived social support had indirect effect on the quality of life via self-effcacy significantly. Perceived stress had no direct and indirect effect on the quality of life significantly. Revised model from hypothetical model showed better fit to the data by eliminating unsignificant path. From results of this study we suggest that to improve quality of life of hemodialysis patient nurses provide nursing interventions which improve self-esteem, perceived social support, self-efficacy & perceived health status.

Phytoestrogens display estrogen-like activity because of their structural similarity to human estrogens and exhibit high affinity binding for the estrogen receptors (ERs). The prevalence of phytoestrogens in our diets and the biological effects that they may cause need to be fully examined. ER is the ancestral receptor from which all other steroid receptors have evolved. Although phytoestrogens serve specific signaling functions between the plants and insects, fungi, and bacteria, many chemical signals are often misinterpreted as estrogenic signals in non-target organisms such as vertebrates. There are no ERs in plants or in their most common partners, insects. However, Rhizobium soil bacteria have NodD proteins which is an intended target of phytoestrogen signaling and share genetic homology with the ER. These two evolutionarily distant receptors both recognize and respond to a shared group of chemical signals and ligands, including both agonists and antagonists. This review briefly summarizes estrogen and estrogen receptors, kinds of important phytoestrogens, their health effects as well as some of the evolutionary aspects of mechanism by which phytoestrogen mimics the endogenous ER signaling in our body.

Generally, large amounts of DOP(Di-Octyl Phthalate) chemicals are used as plasticizers in PVC compound manufacturing processes. However, it is very important to collect DOP species immediately from a workplace in order to protect worker's heath and recover them. To accomplish these objectives, we need to understand the droplet formation and growth mechanisms of DOP species. In this study, two important parameters such as temperature gradient and residence time were considered to clarify these mechanisms. We found that residence time is very critical to determine the droplet size distribution of DOP, whereas temperature gradient in general operating conditions(less than $-6.8^{\circ}C/cm$) is negligible.
