ch is needed on the topic (especially randomized controlled trials), as evidenced by the low number of interventions found. We recommend more rigorous methods, addressing human factors and reporting technology usage in future research.The nucleocapsid (N) protein is conserved in all four genera of the coronaviruses, namely alpha, beta, gamma, and delta, and is essential for genome functionality. Bioinformatic analysis of coronaviral N sequences revealed two intrinsically disordered regions (IDRs) at the center of the polypeptide. While both IDR structures were found in alpha, beta, and gamma-coronaviruses, the second IDR was absent in deltacoronaviruses. Two novel coronaviruses, currently placed in the Gammacoronavirus genus, appeared intermediate in this regard, as the second IDR structure could be barely discerned with a low probability of disorder. Interestingly, these two are the only coronaviruses thus far isolated from marine mammals, namely beluga whale and bottlenose dolphin, two highly related species; the N proteins of the viruses were also virtually identical, differing by a single amino acid. These two unique viruses remain phylogenetic oddities, since gammacoronaviruses are generally avian (bird) in nature. Lastly, both IDRs, regardless of the coronavirus genus in which they occurred, were rich in Ser and Arg, in agreement with their disordered structure. It is postulated that the central IDRs make cardinal contributions in the multitasking role of the nucleocapsid protein, likely requiring structural plasticity, perhaps also impinging on coronavirus host tropism and cross-species transmission.[This retracts the article on p. 15 in vol. 7, PMID 23423690.].
This study investigates correlations between circulating microRNAs (miRNAs) and obesity-related parameters among young women (aged 20-30 years old) in Korea.
We analyzed TaqMan low density arrays (TLDAs) of circulating miRNAs in 9 lean (body mass index [BMI] < 25 kg/m
) and 15 obese (BMI > 25 kg/m
) women. We also performed gene ontology (GO) analyses of the biological functions of predicted miRNA target genes, and clustered the results using the database for annotation, visualization and integrated discovery.
The TLDA cards contain 754 human miRNAs; of these, the levels of 8 circulating miRNAs significantly declined (> 2-fold) in obese subjects compared with those in lean subjects, including miR-1227, miR-144-5p, miR-192, miR-320, miR-320b, miR-484, miR-324-3p, and miR-378. Among them, miR-484 and miR-378 displayed the most significant inverse correlations with BMI (miR-484, r = -0.5484,
= 0.0056; miR-378, r = -0.5538,
= 0.0050) and visceral fat content (miR-484, r = -0.6141,
= 0.0014; miR-378, r = -0.6090,
= 0.0017). GO analysis indicated that genes targeted by miR-484 and miR-378 had major roles in carbohydrate and lipid metabolism.
Our result showed the differentially expressed circulating miRNAs in obese subjects compared to lean subjects. Although the mechanistic study to reveal the causal role of miRNAs remains, these miRNAs may be novel biomarkers for obesity.

The expansion of menu labeling to restaurants has created a need to study customers' behavior toward nutrition information. Therefore, the purpose of this research was to compare college students' behavior toward nutrition information communication between Korea and the US. This study consisted of three objectives 1) to compare the frequency of usage as well as degree of trust regarding smartphone-based communication channels in the acquisition of nutrition information among college students between Korea and the US, 2) to compare knowledge-sharing behavior related to nutrition information among college students between Korea and the US, and 3) to identify the role of country in the process of knowledge-sharing behavior.
A survey was distributed via the web to college students in Korea and the US. Data were collected in the 2nd week of March 2017. Completed responses were collected from 423 Koreans and 280 Americans. Differences between Koreans and Americans were evaluated for statistical significance usire customer behavior toward nutrition information acquisition and sharing between Korea and the US. Comparative research on nutrition information revealed differences among the different countries. Therefore, this study contributes to the body of knowledge on the nutrition information research, in particular, by providing a comparison study between countries.
Dietary factors are important contributors to cardiometabolic and cancer mortality. We examined the secular trends of nine dietary factors (fruits, vegetables, whole grains, nuts and seeds, milk, red meat, processed meat, sugar-sweetened beverages, and calcium) and the associated burdens of cardiometabolic and cancer mortality in Korea using representative cross-sectional survey data from 1998 to 2016.
Using dietary data from Korean adults aged ≥ 25 years in the Korea National Health and Nutrition Examination Survey (KNHANES), we characterized secular trends in intake levels. We performed comparative risk assessment to estimate the population attributable fraction and the number of cardiometabolic and cancer deaths attributable to each dietary factor.
A total of 231,148 cardiometabolic and cancer deaths were attributable to nine dietary risk factors in Korea from 1998 to 2016. Suboptimal intakes of fruits and whole grains were the leading contributors. Although the intakes of fruits, vegetables, and who, vegetables, and whole grains and unfavorable changes in the intakes of processed meat and sugar-sweetened beverages over the past few decades. Our data suggest that to reduce the chronic disease burden in Korea, more effective nutritional policies and interventions are needed to target these dietary risk factors.
To describe the data-based development of a food frequency questionnaire (FFQ) for dietary evaluation of Korean preschool children.
Development of the FFQ was based on the data from 2,766 preschool children aged 1-5 years, who had completed 24-hour dietary recalls in the 2009-2013 Korea National Health and Nutrition Examination Survey. We selected the food list based on the results of nutritional contribution and between-person variability for energy and 13 nutrients. We selected 88 foods with over 80% of total contribution to each nutrient and with over 80% of accumulated
for each nutrient. selleck kinase inhibitor A dish containing any of the 88 foods in the recipe was listed, and a total of 903 dishes were extracted. Among the 903 dishes, we selected 438 dishes contributing more than 1% of total consumption.
FFQ included 116 dish items combined from 438 dishes based on nutrient profile and recipe. Quantities of dietary intake were assessed by nine categories of frequency and portion size option. In addition, when comparing the food portions of children with the reference portion size, subjects would be asked to select one of three response categories (less, similar, and more) and then to record the amount as a percentage for the reference portion.
