Imaging plays a key role in the diagnosis and characterization of thyroid diseases, and the information provided by imaging studies is essential for management planning. A referral guideline for imaging studies may help physicians make reasonable decisions and minimize the number of unnecessary examinations. The Korean Society of Thyroid Radiology (KSThR) developed imaging guidelines for thyroid nodules and differentiated thyroid cancer using an adaptation process through a collaboration between the National Evidence-based Healthcare Collaborating Agency and the working group of KSThR, which is composed of radiologists specializing in thyroid imaging. When evidence is either insufficient or equivocal, expert opinion may supplement the available evidence for recommending imaging. Therefore, we suggest rating the appropriateness of imaging for specific clinical situations in this guideline.

Aging is a progressive process, and it may lead to the initiation of neurological diseases. In this study, we investigated the effects of wild Indian Curcuma longa using a Morris water maze paradigm on learning and spatial memory in adult and D-galactose-induced aged mice. In addition, the effects on cell proliferation and neuroblast differentiation were assessed by immunohistochemistry for Ki67 and doublecortin (DCX) respectively. The aging model in mice was induced through the subcutaneous administration of D-galactose (100 mg/kg) for 10 weeks. C. longa (300 mg/kg) or its vehicle (physiological saline) was administered orally to adult and D-galactose-treated mice for the last three weeks before sacrifice. The administration of C. longa significantly shortened the escape latency in both adult and D-galactose-induced aged mice and significantly ameliorated D-galactose-induced reduction of cell proliferation and neuroblast differentiation in the subgranular zone of hippocampal dentate gyrus. In addition, the administration of C. longa significantly increased the levels of phosphorylated CREB and brain-derived neurotrophic factor in the subgranular zone of dentate gyrus. These results indicate that C. longa mitigates D-galactose-induced cognitive impairment, associated with decreased cell proliferation and neuroblast differentiation, by activating CREB signaling in the hippocampal dentate gyrus.

Acute pancreatitis can range from a mild, self-limiting disease requiring no more than supportive care, to severe disease with life-threatening complications. With the goal of providing a recommendation framework for clinicians to manage acute pancreatitis, and to contribute to improvements in national health care, the Korean Pancreatobiliary Association (KPBA) established the Korean guidelines for acute pancreatitis management in 2013. However, many challenging issues exist which often lead to differences in clinical practices. In addition, with newly obtained evidence regarding acute pancreatitis, there have been great changes in recent knowledge and information regarding this disorder. Therefore, the KPBA committee underwent an extensive revision of the guidelines. The revised guidelines were developed using the Delphi method, and the main topics of the guidelines include the following: diagnosis, severity assessment, initial treatment, nutritional support, convalescent treatment, and the treatment of local complications and necrotizing pancreatitis. Specific recommendations are presented, along with the evidence levels and recommendation grades.

In order for a novel test method to be applied for regulatory purposes, its reliability and relevance, I.e., reproducibility and predictive capacity, must be demonstrated, Here, we examine the predictive capacity of a novel non-radioisotopic local lymph node assay, LLNA:BrdU-FCM (5-bromo-2`-deoxyuridine-flow cytome-try), with a cutoff approach and inferential statistics as a prediction model. 22 reference substances in OECDTG429 were tested with a concurrent positive control. Hexylcinnamaldehyde 25%(PC), and the stimulation index(SI) representing the fold increase in lymph node cells over the vehicle control was obtained. The optimal cutoff SI(2.7≤cutoff<3.5), with respect to predictive capacity, was obtained by a receiver operating character-istic curve, which produced 90.9% accuracy for the 22 substances. To address the inter-test variability in respon-siveness, SI values standardized with PC were employed to obtain the optimal percentage cutoff(42.6≤Cutoff<57.3%of PC), which produced 86.4% accuracy. A test subastance may be diagnosed as a sensitizer if a statistically significant increase in Si is elicited. The parametric one-sided t-test and non-parametric Wilcoxon rank-sum test produced 77.3% accuracy. Similarly, a test substance could be defined as a sensitizer if the SI means of the vehicle control, and of the low, middle, and high concentrations were statistically significantly different, which was test-ed using ANOVA or Kruskal-Wallis, with post hoc analysis, Dunnett, or DSCF(Dwass-Steel-Critchlow-Fligner), respectively, depending on the equal variance test, producing 81.8% accuracy. The absolute SI-based cutoff approach produced the best predictive capacity, however the discordant decisions between prediction models need to be examined further.

Background: Korea has shown a rapid pace of aging and has become an aged society in a shorter period than Western countries. Therefore, it is important that middle-aged workers maintain their ability to work in the industrial field at the maximum level while maintaining their health. The purpose of this study was to analyze the factors affecting work ability and to use this data to maintain the working ability of middle-aged workers in the future. Methods: From 2015 to 2017, we surveyed 371 street cleaners who visited a health center for health promotion in a metropolitan city. The relationship between the general characteristics of the survey subjects and the Work Ability Index (WAI) was confirmed by a univariate analysis. Statistically significant (p
Metabolite Profiling of the Response of Burdock Roots to Copper Stress

<P><I>Arctium lappa</I> L. (Asteraceae), also known as burdock, has a long history of cultivation as a dietary vegetable worldwide. Stress in plants disrupts metabolic homeostasis and requires adjustment of metabolic pathways. Exposure to heavy metals is one of the most prevalent environmental stresses encountered by plants. In this study, metabolite profiling based on <SUP>1</SUP>H NMR and GC–MS was used to obtain a holistic view of the response of burdock roots to copper stress. The principal component analysis model generated from the NMR data showed significant separation between groups. Copper-treated burdock roots were characterized by increased levels of phenols and decreased levels of primary metabolites. These results suggest that copper stress leads to activation of the phenylpropanoid pathway and growth inhibition. GC–MS analyses revealed increased levels of unsaturated fatty acids and decreased levels of sterols in the copper-treated group. Changes in metabolite concentrations were analyzed by UPLC/QTRAP–MS, and the significances were confirmed by two-way analysis of variance and Bonferroni’s test. Interestingly, linoleic acid was increased about 2.7-fold, from 316 ± 64.5 to 855 ± 111 ppm, in the group treated with copper for 6 days. This study demonstrates that metabolomic profiling is an effective analytical approach to understanding the metabolic pathway(s) associated with copper stress in burdock roots.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jafcau/2015/jafcau.2015.63.issue-4/jf503193c/production/images/medium/jf-2014-03193c_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jf503193c'>ACS Electronic Supporting Info</A></P>
