  • BACKGROUND/OBJECTIVES: To compare five indices of adherence to the Mediterranean Diet (MD) among adults living in the Mediterranean region. SUBJECTS/METHODS: A total of 100 healthy Lebanese adults aged between 18 and 65 years. Face-to-face interviews to collect sociodemographic and medical information, to take anthropometric measurements, and to fill a validated, culturally adapted, food frequency questionnaire (FFQ). The score for each item was calculated following the recommendations for each corresponding index. The five MD indices were Mediterranean Diet Scale (MDScale), Mediterranean Food Pattern (MFP), MD Score (MDS), Short Mediterranean Diet Questionnaire (SMDQ), and the MedDiet score. RESULTS: Significant correlations were detected between items with P-values < 0.001. Minimal agreement was seen between MDScale and MedDiet score and maximal agreement between MDS and MedDiet score. Univariate and multivariate analyses showed that MDS and MedDiet scores had significant correlations with fiber and olive oil intake, main components of the MD. MDScale showed a significant correlation with waist-to-hip ratio and with total energy intake but none of the five indices was correlated to body mass index (BMI). CONCLUSIONS: The indices that showed the highest correlation with variables related to the MD are the MDScale and the MedDiet score; therefore, they can be used to assess our future study populations. Based on the current results, more than half of the study population was non-adherent to the MD and adherence to this diet did not appear to protect against being overweight ($BMI{\geq}30$).

Maxillary Distraction Osteogenesis Using $TS-MD^{(R)}$ (Trans-sinusoidal Maxillary distractor) on Cleft Patients (Trans-sinusoidal maxillary distractor($TS-MD^{(R)}$)를 이용한 구순구개열 환자에서의 상악골 골신장술)

  • Purpose: Maxillary hypoplasia is a common developmental problem of cleft lip and palate. Fair results with distraction osteogenesis have been reported especially when these patients need a large amount of maxillary advancement, instead of orthognathic surgery. The purpose of this study is to evaluate the clinical results with a relatively new distractor, $TS-MD^{(R)}$ (Trans-sinusoidal maxillary distractor, KLS Martin, Tuttlingen, Germany) which was used for the advancement of the maxilla in the cleft patients. Patients and Method: Distraction osteogenesis using $TS-MD^{(R)}$ was performed for four CLP patients (three males and one female) who had maxillary hypoplasia. All patients were over 16 years old. As three patients showed mandibular prognathism as well, bilateral sagittal split ramus osteotomy for mandibular setback was performed at the same time. After consolidation periods of 4 to 12 weeks, the distraction devices were removed and miniplates were placed for simultaneous internal fixation. Results: Three patients showed a large amount of incisal overbite but one patient did not have sufficient maxillary advancement. Le Fort I osteotomy, maxillary advancement and internal fixation should have been performed for the patient when removing the distraction devices. Different from the $clinician{\box}s$ expectation, the amount of maxillary advancement using $TS-MD^{(R)}$ was not sufficient, although the device has rigid mechanical property. Rotation of maxilla during distraction forward and downward was also observed. Conclusion: Even though the maxillary advancement with $TS-MD^{(R)}$ device could be achieved, the clinical control of some characteristics related with the device was necessary. More clinical studies on $TS-MD^{(R)}$ should be performed.

  • 암호학적으로 안전한 해쉬 함수는 디지털 서명, 메시지 인증, 키 유도와 같은 분야에서 중요한 암호 도구이다 현재까지 제안된 소프트웨어로 고속 수행이 가능한 해쉬 함수들의 대부분은 Rivest가 제안한 MD4의 설계 원리에 기반을 두고 있다. 이들 MD 계열 해쉬 함수 중에서 현재 안전하다고 알려진 전용 해쉬 함수는 SHA-1, RIPEMD-160, HAVAL 등이다. 본 논문에서는 이들 세 가지 해쉬 함수들의 장점에 기반하여 이들 함수들이 가지는 안전성을 최대한 유지하면서 보다 효율적인 새로운 해쉬 함수를 제안한다. 제안된 해쉬 함수는 임의 길이 메시지를 512비트 단위로 처리하여 160비트의 출력을 가지며, 입력 데이터에 의존한 순환이동(data-dependent rotation)의 특징을 가짐으로써 기존에 알려진 공격에 강인함을 보장한다. 또한 제안된 해쉬 함수를 이용한 메시지 인증 코드(Message Authentication Code:MAC) 구성 알고리즘을 제안한다 MAC은 두 번째 입력, 즉 비밀키를 가진 해쉬 함수로 keyed 해쉬 함수라고 하며, 메시지 출처 인증과 무결성 확인을 제공한다. 제안된 MAC은 최대 160-비트의 키를 사용하며 해쉬 결과보다 같거나 적은 MAC 결과를 가지며, 성능 면에서 사용되는 해쉬 함수에 비해 약 10% 정도의 저하를 초래한다.

  • We have studied Meckel's diverticulum(MD) of the duck(Anas platyrhynchos platyrhyncos, Linne) by histological and immunohistochemical methods. Because MD were first observed in 2 weeks after hatching, tissues were taken from 2 weeks to 32 weeks after hatching groups. MD were observed as like any parts of intestinal tract that composed with simple columnar epithelium and numerous mucosal gland especially, cecum except that many lymphocytes were exist in this study. Also a number of bovine chromogranin(BCG)-, serotonin, and somatostatin(SOM)-immunoreactive cells were observed in epithelium and submucosal gland in this study, so it could be suggest that the MD of the duck serve as some digestive and lymphatic functions.

  • Refinement of NMR structures by molecular dynamics (MD) simulations with a solvent model has improved the structural quality. In this study, we applied MD refinement with the generalized Born (GB) implicit solvent model to protein structure determined under membrane-like environments. Despite popularity of the GB model, its applications to the refinement of NMR structures of hydrophobic proteins, in which detergents or organic solvents enclose proteins, are limited, and there is little information on the use of another GB parameter for these cases. We carried out MD refinement of crambin NMR structure in dodecylphosphocholine (DPC) micelles (Ahn et al., J. Am. Chem. Soc. 2006, 128, 4398-4404) with GB/Surface area model and two different surface tension coefficients, one for aquatic and the other for hydrophobic conditions. Our data show that, of two structures by MD refinement with GB model, the one refined with the parameter to consider hydrophobic condition had the better qualities in terms of precision and solvent accessibility.

  • Chlorosulfolipids(CSLs)는 1960 년대에 해조류에서 발견되었다. 하지만 당시 기술력으로는 해조류에서 CSLs 를 추출해 내는 것이 불가능하여 연구가 중단 되었다. 그 후로 40 년 뒤 2009 년이 되어서야 CSLs 를 추출할 수 있게 되었다. CSLs 가 독성을 지니고 있다는 연구가 보고 되어 왔다. 하지만 이 CSL 가 형성하는 구조를 실험으로 알수가 없고 아직까지 학회에 보고 된 적이 없다. 따라서 본 연구원이 MD 시뮬레이션을 이용하여 CSLs 가 형성하는 세포막의 구조를 알아보기 위하여 Coarse-grain 모델을 이용한 CSLs 의 Self-Assembly 연구와 이 결과로 인해 얻은 정보로 atomistic 모델을 만들어서 MD 시뮬레이션을 수행하였다.

  • Morbihan disease (MD) is a rare condition that involves rosaceous lymphedema or erythematous lymphedema of the middle and upper thirds of the face. It typically affects the periorbital region, forehead, glabella, nose, and cheeks. The etiology of MD remains unclear, and its diagnosis is challenging. MD often tends to be unresponsive to therapies commonly used to treat rosacea, including corticosteroids, isotretinoin, and antibiotics. Surgical treatments have therefore been attempted, but most cases showed unsatisfactory responses. These problems could have resulted from an incorrect recognition and interpretation of the pathophysiology of MD and inaccurate planning of the operation, resulting in recurrence or exacerbation of edema.

  • This study proposes the feasibility for automatic classification of sleep/wakefulness using nasal pressure in patients with sleep-disordered breathing (SDB). First, SDB events were detected using the methods developed in our previous studies. In epochs for normal breathing, we extracted the features for classifying sleep/wakefulness based on time-domain, frequency-domain and non-linear analysis. And then, we conducted the independent two-sample t-test and calculated Mahalanobis distance (MD) between the two categories. As a results, $SD_{LEN}$ (MD = 0.84, p < 0.01), $P_{HF}$ (MD = 0.81, p < 0.01), $SD_{AMP}$ (MD = 0.76, p = 0.031) and $MEAN_{AMP}$ (MD = 0.75, p = 0.027) were selected as optimal feature. We classified sleep/wakefulness based on support vector machine (SVM). The classification results showed mean of sensitivity (Sen.), specificity (Spc.) and accuracy (Acc.) of 60.5%, 89.0% and 84.8% respectively. This method showed the possibilities to automatically classify sleep/wakefulness only using nasal pressure.

  • This study was conducted to develop new lines expressing the characteristic of early flowering by introducing MdMADS2 gene in chrysanthemum (Dendranthema grandiflorum (Ramat.) Kitamura) ‘Zinba'. Transformation of chrysanthemum was conducted by Agrobacterium tumefaciens LBA4404 harboring the binary vector containing MdMADS2 controlled by double CaMV 35S promoters. Ninety three shoots were regenerated from 1,463 leaf segment explants cultured on the first selection medium (MS basal salts + 1.0 mg/L BA + 0.5 mg/L IAA + 10 mg/L kanamycin + 400 mg/L cefotaxime, pH 5.8) after co-cultivation, and 20 out of the 93 shoots rooted on the second selection medium containing 20 mg/L kanamycin and 400 mg/L cefotaxime. Many escapes (98.6%) were removed on the selection stage for rooting. Nineteen lines were confirmed as transgenic plant with transgene by PCR analysis. Six transgenic plants flowered 2-11 days earlier than non-transgenic plant without big change of phenotype, and especially, 3 (Mo-7, Mo-11, Mo-17) out of 6 transgenic lines showed a significant reduction in days to flowering compared to non-transgenic plant. Introduction and expression of MdMADS2 gene in them were confirmed by Southern and real-time PCR analyses, respectively.

  • Flowers of Magnolia denudata has been reported to possess a variety of pharmacological activities. In this study, we investigated the anti-inflammatory effects and mechanism of the water extract of Flowers of Magnolia denudata(MD) in lipopolysacchride (LPS)-mediated inflammatory mediators in murine peritoneal macrophages. MD itself does not have any toxic effects in murine peritoneal macrophages. MD inhibits LPS-induced nitric oxide (NO), tumor necrosis factor $(TNF)-{\alpha}$, IL-6 and IL-12 production in murine peritoneal macrophages. Furthermore, we have found that MD inhibited LPS-induced $NF-{\kappa}B$ but not c-Jun N-terminal kinase (JNK), p38 and extracellular signal-ragulated kinase (ERK) activation. These results suggested that MD inhibit LPS-induced production of $TNF-{\alpha}$, IL-6 and IL-12 via suppression of the $NF-{\kappa}B$ activation.
