Adolescents’ Estimation of Energy Content of Standard Portion Size of Foods and Its Association with Body Mass Index  [PDF]
Mi-Kyeong Choi, Min-Jung Ko, Mi-Hyun Kim
Food and Nutrition Sciences (FNS) , 2012, DOI: 10.4236/fns.2012.310177
Abstract: The purpose of this study is to identify the adolescents’ knowledge of the energy content of the standard portion size of foods and to investigate the association between their knowledge and energy intake and also body mass index (BMI). A total of 251 middle school adolescents participated in this study. Participants’ knowledge was assessed based on their estimation of the energy content of the standard portion size of foods. To estimate the energy intake of the subjects, 24-hr recall was used. The percentage of participants who accurately estimated (that is within 20% of the true value) the energy content of the standard portion size was calculated for each of the 32 typical foods. The food for which the most participants revealed the accurate estimation was cooked rice (39.5%). The proportion of students who overestimated the energy contents was highest for vegetables (98%), and oils and sugar (90%). The female students were more likely than males to provide the accurate estimation of energy contents for standard portion size of foods. After adjusting for age and sex, the estimation level ([estimation value/true value] × 100) of the energy content of some foods had a significant positive relationship with BMI, but had no significant relationship with reported energy intake. From these results, we concluded that the knowledge of energy content of food was poor among middle-school adolescents, with some gender difference, and that their estimation of the calorie contents of foods increased along with their BMI.

Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2016, DOI: 10.4236/jcdsa.2016.63011
Abstract: Forsythia fructus has been shown to have antioxidative, anti-inflammatory, antibacterial, anti-aging and whitening effects. Hoechunyangkyeok-san (Forsythia viridissima-prescription) is a traditional herbal medicine, which has been clinically used for treating febrile and inflammatory disorders. This work was carried out to investigate the skin whitening effects of Forsythia viridissima-prescription extract (a hydrolyzed extract of Hoechunyangkyeok-san: SID White HYC) on skin. The effects of SID White HYC were assessed the melanin contents in B161 melanoma cells and the pigmented equivalent with HMB45 and Fontana Masson staining in 3D skin model. Then, we examined the expression of major pigment enzymes regulating melanin synthesis and melanosome transport related proteins in B16F1 cells. SID White HYC significantly inhibited the melanin synthesis (56.7% and 30.6% inhibition at 100 μg/mL, intracellular and secreted, respectively) in B16F1 cells and 3D skin model. In addition, western blotting analysis showed that SID White HYC reduced the expression of melanin synthesis and melanosome transport related proteins in B16F1 cells. In clinical trials, the cream containing 0.05% SID White HYC showed skin depigmentation effect without any irritation. These results suggest that SID White HYC may be useful inhibition of melanogenesis and melanosome transport. Therefore, SID White HYC may have potential as a skin-whitening ingredient in cosmetics.
Different metastatic pattern according to the KRAS mutational status and site-specific discordance of KRAS status in patients with colorectal cancer
Kim Mi-Jung,Lee Hye,Kim Jee,Kim Yu
BMC Cancer , 2012, DOI: 10.1186/1471-2407-12-347
Abstract: Background We evaluated the association between a KRAS mutational status and various clinicopathologic features including the metastatic pattern in patients with metastatic or recurrent colorectal cancer (MRCRC). The concordance rates of the KRAS status between primary tumor sites and paired metastatic organs were also analyzed. Methods The KRAS mutational status in codons 12, 13, and 61 from formalin-fixed sections of both primary tumors and related metastases was determined by sequencing analysis. One hundred forty-three Korean patients with MRCRC with available tissues (resection or biopsy) from both primary tumors and related metastatic sites were consecutively enrolled. Results The KRAS mutation rate was 52.4% (75/143) when considering both the primary and metastatic sites. When the relationship between the KRAS status and initial metastatic sites at the time of diagnosis of MRCRC was analyzed, lung metastasis was more frequent as the initial metastatic site in patients with the KRAS mutation than in patients without the KRAS mutation (45.3% vs. 22.1%; P = 0.003). However, liver (37.3% vs. 70.6%; P < 0.001) or distant lymph node metastases (6.7% vs. 19.1%; P = 0.025) were less frequent as the initial metastatic organ in patients with the KRAS mutation than in patients without the KRAS mutation. The discordance rate of KRAS mutational status between primary and paired metastatic sites other than the lung was 12.3% (13/106). Compared with primary tumor sites, the KRAS discordance rate was significantly higher in matched lung metastases [32.4% (12/37)] than in other matched metastatic organs (P = 0.005). Conclusions Organs initially involved by distant metastasis were different according to the KRAS mutational status in MRCRC patients. The concordance rate (87.7%) of the KRAS mutation status at metastatic sites other than the lung was generally high compared with primary tumor sites; however, lung metastasis had a high rate of KRAS discordance (32.4%).

Abstract: Diabetes is characterized by a proinflammatory state, and several inflammatory processes have been associated with both type 1 and type 2 diabetes and the resulting complications. High glucose levels induce the release of proinflammatory cytokines. Fisetin, a flavonoid dietary ingredient found in the smoke tree (Cotinus coggygria), and is also widely distributed in fruits and vegetables. Fisetin is known to exert anti-inflammatory effects via inhibition of the NF- B signaling pathway. In this study, we analyzed the effects of fisetin on proinflammatory cytokine secretion and epigenetic regulation, in human monocytes cultured under hyperglycemic conditions. Human monocytic (THP-1) cells were cultured under control (14.5?mmol/L mannitol), normoglycemic (NG, 5.5?mmol/L glucose), or hyperglycemic (HG, 20?mmol/L glucose) conditions, in the absence or presence of fisetin. Fisetin was added (3–10? M) for 48?h. While the HG condition significantly induced histone acetylation, NF- B activation, and proinflammatory cytokine (IL-6 and TNF- ) release from THP-1 cells, fisetin suppressed NF- B activity and cytokine release. Fisetin treatment also significantly reduced CBP/p300 gene expression, as well as the levels of acetylation and HAT activity of the CBP/p300 protein, which is a known NF- B coactivator. These results suggest that fisetin inhibits HG-induced cytokine production in monocytes, through epigenetic changes involving NF- B. We therefore propose that fisetin supplementation be considered for diabetes prevention. 1. Introduction Diabetes and its complications are known for their chronic inflammatory properties. Inflammation is a defense reaction of host tissue against diverse insults. Although normally a beneficial process, when it occurs over prolonged periods, inflammation can be deleterious to cells [1]. Hyperglycemia has been implicated in diabetes-induced inflammatory disease and several diabetes-related complications [2, 3]. It has been reported to induce oxidative stress [4, 5]. In addition, high levels of glucose can activate the proinflammatory transcription factor nuclear κB (NF-κB), resulting in increased inflammatory chemokine and cytokine release [6, 7]. We and other researchers have recently shown that diabetic conditions activate inflammatory gene expression and monocyte activation by inducing epigenetic changes and chromatin remodeling [8, 9]. However, the exact molecular mechanisms induced by hyperglycemia are not fully resolved. NF-κB is required for the expression of many inflammatory genes. Several of these genes have been associated
Angiomyofibroblastoma of the vulva: A case report with literature review  [PDF]
Jung Ho Park, Mi Kyung Shin, Maria Lee, Sung Taek Park, Sung-Ho Park, Hong-Bae Kim
Case Reports in Clinical Medicine (CRCM) , 2013, DOI: 10.4236/crcm.2013.23060

Angiomyofibroblastoma (AMF) is a rare kind of soft tissue tumor that occurs predominantly in the vulva. Due to their location, clinicians often confuse AMF with Bartholin’s cyst or perineal hernia. Radiological evaluation is performed to rule out perineal hernia and invasive neoplasm. Like other benign mesenchymal tumors of vulva, AMF shows indolent behavior and rarely recurs after complete surgical excision.

Management of Refractory Tracheal Collapse in a Dog using Self-Expanding Intraluminal Prosthesis
Seung-Gon Lee,Mi-Jung Kim,Changbaig Hyun
Journal of Animal and Veterinary Advances , 2012,
Abstract: Tracheal collapse is commonly seen in small breed dogs and is caused by a progressive weakening of the tracheal rings. A 5 year-old male Yorkshire terrier (weighing 1.97 kg) was presented Veterinary Teaching Hospital at Kangwon National University (S. Korea) with goose honking cough and cyanosis. On the radiographical and endoscopical examination, trachea was collapsed from the mid of cervical trachea to the mid of thoracic trachea. A self-expanding intraluminal stent (Zilver 635 biliary stents, COOK, USA) was implanted to restore collapsed trachea. After implantation, the dog was medicated with cough suppressant (methylephedrine, 2 mg kg 1 BID), prednisolone (0.5 mg kg 1 BID) and cefazoline (5 mg kg 1 BID) for 2 weeks, to reduce side effects from metallic stenting. Clinical improvement was noticed right after implantation. Although mild transient dry cough lasted for a month, the dog was clinically recovered from tracheal collapse.
Tuning photoluminescence of organic rubrene nanoparticles through a hydrothermal process
Kim Mi,Cho Eun,Park Dong,Jung Hyunjung
Nanoscale Research Letters , 2011,
Abstract: Light-emitting 5,6,11,12-tetraphenylnaphthacene (rubrene) nanoparticles (NPs) prepared by a reprecipitation method were treated hydrothermally. The diameters of hydrothermally treated rubrene NPs were changed from 100 nm to 2 μm, depending on hydrothermal temperature. Photoluminescence (PL) characteristics of rubrene NPs varied with hydrothermal temperatures. Luminescence of pristine rubrene NPs was yellow-orange, and it changed to blue as the hydrothermal temperature increased to 180°C. The light-emitting color distribution of the NPs was confirmed using confocal laser spectrum microscope. As the hydrothermal temperature increased from 110°C to 160°C, the blue light emission at 464 to approximately 516 nm from filtered-down NPs was enhanced by H-type aggregation. Filtered-up rubrene NPs treated at 170°C and 180°C exhibited blue luminescence due to the decrease of intermolecular excimer densities with the rapid increase in size. Variations in PL of hydrothermally treated rubrene NPs resulted from different size distributions of the NPs.
Difficulties in analytic computation for relative entropy of entanglement
Hungsoo Kim,Mi-Ra Hwang,Eylee Jung,DaeKil Park
Physics , 2010, DOI: 10.1103/PhysRevA.81.052325
Abstract: It is known that relative entropy of entanglement for entangled state $\rho$ is defined via its closest separable (or positive partial transpose) state $\sigma$. Recently, it has been shown how to find $\rho$ provided that $\sigma$ is given in two-qubit system. In this paper we study on the inverse process, i.e. how to find $\sigma$ provided that $\rho$ is given. It is shown that if $\rho$ is one of Bell-diagonal, generalized Vedral-Plenio and generalized Horodecki states, one can always find $\sigma$ from a geometrical point of view. This is possible due to the following two facts: (i) The Bloch vectors of $\rho$ and $\sigma$ are identical with each other (ii) The qubit-interaction vector of $\sigma$ can be computed from a crossing point between minimal geometrical object, in which all separable states reside in the presence of Bloch vectors, and a straight line, which connects the point corresponding to the qubit-interaction vector of $\rho$ and the nearest vertex of the maximal tetrahedron, where all two-qubit states reside. It is shown, however, that these nice properties are not maintained for the arbitrary two-qubit states.

Mathematics , 2014,
Abstract: We classify all of real hypersurfaces $M$ with Reeb invariant shape operator in complex hyperbolic two-plane Grassmannians $SU_{2,m}/S(U_2{\cdot}U_m)$, $m \geq 2$. Then it becomes a tube over a totally geodesic $SU_{2,m-1}/S(U_2{\cdot}U_{m-1})$ in $SU_{2,m}/S(U_2{\cdot}U_m)$ or a horosphere whose center at infinity is singular and of type $JN \in {\mathfrak J}N$ for a unit normal vector field $N$ of $M$.
