  • To elucidate the biodiversity of plant growth-promoting rhizobacteria (PGPR) in Korea, 7,638 bacteria isolated from the rhizosphere of plant species growing in many different regions were screened. A large number of PGPR were identified by testing the ability of each isolate to promote the growth of cucumber seedlings. After redundant rhizobacteria were removed via amplified rDNA restriction analysis, 90 strains were finally selected as PGPR. On the basis of 16S ribosomal RNA sequences, 68 Gram-positive (76%) and 22 Gram-negative (24%) isolates were assigned to 21 genera and 47 species. Of these genera, Bacillus (32 species) made up the largest complement, followed by Paenibacillus (19) and Pseudomonas (11). Phylogenetic analysis showed that most of the Grampositive PGPR fell into two categories: low- and high- G+C (Actinobacteria) strains. The Gram-negative PGPR were distributed in three categories: ${\alpha}$-proteobacteria, ${\beta}$- proteobacteria, and ${\gamma}$-proteobacteria. To our knowledge, this is the largest screening study designed to isolate diverse PGPR. The enlarged understanding of PGPR genetic diversity provided herein will expand the knowledge base regarding beneficial plant-microbe interactions. The outcome of this research may have a practical effect on crop production methodologies.

  • This study was conducted to assess improvements in nutritional status following the application of nutrition education to elderly patients in a long-term care hospital. The study was carried out from January to May 2009, during which a preliminary survey, a pretest, the application of nutrition education, and a post-test were applied in stages. The number of subjects at pretest was 81, and the number of participants included in the final analysis was 61 (18 men, 43 women), all of whom participated in both the nutrition education program and the post-test. The survey consisted of general demographic items, health behaviors, dietary behaviors, the Nutrition Screening Initiative checklist, and nutrient intake assessment (24 hour recall method). The nutrition education program lasted for four weeks. It included a basic education program, provided once a week, and mini-education program, which was offered daily during lunch times. The survey was conducted before and after the education program using the same assessment method, although some items were included only at pretest. When analyzing the changes in elderly patients after the nutritional education program, we found that, among subjective dietary behaviors, self-rated perceptions of health (P<0.001) and of depression (P<0.001) improved significantly and that dietary behavior scores also improved significantly (P<0.001), while nutritional risk levels decreased. In terms of nutrient intake, subjects' intake of energy, protein, fat, carbohydrate, calcium, phosphorus, iron, vitamin A, thiamin, riboflavin, niacin, and vitamin C all increased significantly (P<0.001). These results indicated that nutritional education is effective in improving the nutritional status of elderly patients. We hope that the results of this study can be used as preliminary data for establishing guidelines for nutrition management tailored to elderly patients in long-term care hospitals.

  • In vitro and greenhouse screening of seven rhizobacterial isolates, AB05, AB10, AB11, AB12, AB14, AB15 and AB17, was conducted to investigate the plant growth promoting activities and inhibition against anthracnose caused by Colletotrichum acutatum in pepper. According to identification based on 16S rDNA sequencing, the majority of the isolates are members of Bacillus and a single isolate belongs to the genus Paenibacillus. All seven bacterial isolates were capable of inhibiting C. acutatum to various degrees. The results primarily showed that antibiotic substances produced by the selected bacteria were effective and resulted in strong antifungal activity against the fungi. However, isolate AB15 was the most effective bacterial strain, with the potential to suppress more than 50% mycelial growth of C. acutatum in vitro. Moreover, antibiotics from Paenibacillus polymyxa (AB15) and volatile compounds from Bacillus subtilis (AB14) exerted efficient antagonistic activity against the pathogens in a dual culture assay. In vivo suppression activity of selected bacteria was also analyzed in a greenhouse with the reference to their prominent in vitro antagonism efficacy. Induced systemic resistance in pepper against C. acutatum was also observed under greenhouse conditions. Where, isolate AB15 was found to be the most effective bacterial strain at suppressing pepper anthracnose under greenhouse conditions. Moreover, four isolates, AB10, AB12, AB15, and AB17, were identified as the most effective growth promoting bacteria under greenhouse conditions, with AB17 inducing the greatest enhancement of pepper growth.

  • Background: Breast cancer risk assessment is a helpful method for estimating development of breast cancer at the population level. Materials and Methods: In this cross-sectional study, participants consisted of a group of 3,847 volunteers ($mean{\pm}SD$ age: $463{\pm}7.59$ years) in a convenience sample of women referred to health centers affiliated to Tehran University of Medical Sciences in Tehran, Iran. The risk of breast cancer was estimated by applying the National Cancer Institute's online version of the Gail Risk Assessment Tool. Results: Some 24.9% of women reported having one first-degree female relative with breast cancer, with 8.05% of them having two or more first-degree relatives with breast cancer. The mean five-year risk of breast cancer for all participants was $1.61{\pm}0.73%$, and 9.36% of them had a five-year risk of breast cancer >1.66%. The mean lifetime risk of breast cancer was $11.7{\pm}3.91%$. Conclusions: The Gail model is useful for assessing probability of breast cancer in Iranian women. Based on the their breast cancer risk, women may decide to accept further screening services.

  • The purpose of this study was to analyze the characteristics of Chinese foods in main ingredients, sauces, and cooking methods, and to assess the applicability of kochujang in Chinese foods. Twenty Chinese foods and commercial kochujang were selected by a Chinese head cook. The main ingredients were 24 kinds such as pork, chicken, shrimp, bok choy, bean curd, Chinese noodles etc., which were generally used in Korean foods. The main Chinese sauces were 11 kinds, and soy sauce was used in 12 foods, shang loo tau soy sauce in 2, wine in 8, oyster sauce in 7, rice wine in 6. The classification of cooking units in all Chinese foods was performed and the cooking frequency was deep frying>pan frying>boiling>stir frying>steaming>roasting. The proper amount of kochujang (weight ratio) was decided by pre-test of the Chinese head cook and Chinese food added kochujang was assessed by a Chinese focus group. The overall preference of Chinese food added kochujang was assessed highly and was related to the kinds of sauces, and to the kinds of main ingredients. The foods which used soy sauce or shang loa tau soy sauce were preferred. Sweetness by using kochujang wasn't preferred in several foods. Saltiness and aftertaste by using kochujang didn't affect the food preference, and the intensity of color and pungency were evaluated as a moderate level. An increased amount of kochujang would be possible in several foods. However, the increase in the amount of kochujang for intensive color and pungency in Chinese foods was directly related to the increase of sweetness, which had been discussed as the main problem in lowering the preference. Therefore, the screening of various Chinese foods harmonized with kochujang and the determination of the proper mixing ratio with Chinese sauces are very important. The results of this study could be used as basic data for the promotion of kochujang consumption in the Chinese market.

  • The effects of four extracts of medicinal herbs, Rubus coreanum, Acorus calamus, Morus alba and Rehmannia glutinosa on hair growth activity and acnes control were investigated. In the course of screening natural extracts for hair growth, we found that the extract of dried root of Rubus coreanum has the hair growth promoting effect. After topical application of these extracts to the back of C57BL/6 mice, the earlier conversion of telogen-to-anagen phase was induced. The growth of dermal papilla cells and mouse vibrissae hair follicle cultured in vitro, however, was not affected by treatment of these extracts. Furthermore these extracts do not possesspotent inhibitory effect on $5{\alpha}-reductase$ I and II activity and anti-bacterial effect on Escherichia coli , Propionibacterium acnes, Pityrosporum ovale, Staphylococcus aureus, Staphylococcus epidemidis, and Candida albicans. RT-PCR analysis showed that these extracts did notinduce mRNA levels of growth factors such as insulin-like growth factor-I, keratinocyte growth factor, hepatocyte growth factor and vascular endothelial growth factor in dermal papilla cells. These results suggest that Rubus coreanum has hair growth promoting effect. However, the effects of these materials on the hair growth promotion are not mediated through inhibition of $5{\alpha}-reductase$ I and II activity, stimulation of hair follicle cells and expression of growth factors in the dermal papilla cells.

  • Background: Cancer is a leading cause of death worldwide. A large proportion of cancer deaths are preventable through early detection but there are a range of social, emotional, cultural and financial dimensions that hinder the effectiveness of cancer prevention and treatment efforts. Cancer stigma is one such barrier and is increasingly recognized as an important factor influencing health awareness and promotion, and hence, disease prevention and control. The impact and extent of stigma on the cancer early detection and care continuum is poorly understood in India. Objectives: To evaluate cancer awareness and stigma from multiple stakeholder perspectives in North India, including men and women from the general population, health care professionals and educators, and cancer survivors. Materials and Methods: A qualitative study was conducted with in-depth interviews (IDIs) and focus group discussions (FGDs) among 39 individuals over a period of 3 months in 2014. Three groups of participants were chosen purposively - 1) men and women who attended cancer screening camps held by the Indian Cancer Society, Delhi; 2) health care providers and 3) cancer survivors. Results: Most participants were unaware of what cancers are in general, their causes and ways of prevention. Attitudes of families towards cancer patients were observed to be positive and caring. Nevertheless, stigma and its impact emerged as a cross cutting theme across all groups. Cost of treatment, lack of awarenes and beliefs in alternate medicines were identified as some of the major barriers to seeking care. Conclusions: This study suggests a need for spreading awareness, knowledge about cancers and assessing associated impact among the people. Also Future research is recommended to help eradicate stigma from the society and reduce cancer-related stigma in the Indian context.

  • Cancers can be detected in early stages through awareness of suspicious symptoms or by specific actions undertaken by individuals or participation in medical checks or screening programmes. The present research had three objectives: to assess the knowledge of Romanian women who have relatives with cancer with regard to cancer symptoms and detection methods; to identify socio-demographics factors influencing their level of knowledge; provide information regarding the attitudes of women from the study regarding medical help-seeking in case of any symptom which might be associated with cancer. This cross-sectional study was performed in an oncological hospital from Cluj-Napoca, Romania. It involved 160 women aged 18-70 years, who had relatives with cancer. An anonymous questionnaire was filled in by the participants. The results showed that around 10% of the study sample recognized all the 8 listed symptoms associated with cancer and all the 7 listed methods for cancer detection. The results of the linear regression analyses show that the level of knowledge regarding both symptoms and methods for detection was higher among younger women (B=-0.390, p<0.01, respectively B=-0.260; p<0.01), among those living in urban areas (B=0.872, p<0.01, respectively B=0.676; p<0.01) and those having higher educational level (B=0.883, p<0.001, respectively B=0.536; p<0.001). The majority of the participants agreed with the importance of looking for medical help within weeks up to one month in case that a symptom which might be associated with cancer was observed. The study underlines the necessity that much more information should be given to women who have relatives with cancer about what they can do to detect cancer in an early stage. This is especially needed for older women, women living in rural areas and women having a lower educational level.

  • Background: Health risks associated with unhealthy behaviours in adolescent and university students contribute to the development of health problems in later life. During the past twenty years, there has been a dramatic increase in public, private, and professional interest in preventing disability and death through changes in lifestyle and participation in screening programs. The aim of the study was to evaluate university students' health-promoting lifestyle behaviour for cancer prevention. Method: This study was carried out on university students who had education in sports, health and social areas in Celal Bayar University, Manisa, Turkey. The health-promoting lifestyles of university students were measured with the "health-promoting lifestyle profile (HPLP)" The survey was conducted from March 2011 to July 2011 and the study sample consisted of 1007 university students. T-test, ANOVA and multiple regression analyses were used for statistical analyses. Results: In the univariate analyses, the overall HPLP score was significantly related to students' school, sex, age, school grades, their status of received health education lessons, place of birth, longest place of residence, current place of residence, health insurance, family income, alcohol use, their status in sports, and self-perceived health status. Healthier behaviour was found in those students whose parents had higher secondary degrees, and in students who had no siblings. In the multiple regression model, healthier behaviour was observed in Physical Education and Sports students, fourth-year students, those who exercised regularly, had a good self-perceived health status, who lived with their family, and who had received health education lessons. Conclusion: In general, in order to ensure cancer prevention and a healthy life style, social, cultural and sportive activities should be encouraged and educational programmes supporting these goals should be designed and applied in all stages of life from childhood through adulthood.
