Soo Kyoung Kim, Ji Cheol Bae, Jong-Ha Baek, Jae Hwan Jee, Kyu Yeon Hur, Moon-Kyu Lee, Jae Hyeon Kim
This study was conducted to investigate whether baseline lung function or change in lung function is associated with the development of metabolic syndrome (MS) in Koreans. We analyzed clinical and laboratory data from 3,768 Koreans aged 40-60 years who underwent medical check-ups over a six-year period between 2006 and 2012. We calculated the percent change in forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) over the study period. We tested for an association between baseline lung function or lung function change during the follow-up period and the development of MS...

Bilal Aftab, Jin Hur
The removal of a commercial humic acid (HA) and changes in its chemical composition were examined for coagulation/flocculation (C/F) processes based on jar tests using two different coagulants at a wide range of pH. ZrCl4 showed a better performance in eliminating HA than Al2SO4 with the same removal rates at lower dosages. The highest removal rates were found at a neutral pH range (5.0-6.5). The HA was further decomposed into three different humic-like components (C1, C2, and C3) by excitation emission matrix coupled with parallel factor analysis (EEM-PARAFAC)...

BACKGROUND: The RNA binding proteins (RBPs) human antigen R (HuR) and Tristetraprolin (TTP) are known to exhibit competitive binding but have opposing effects on the bound messenger RNA (mRNA). How cells discriminate between the two proteins is an interesting problem. Machine learning approaches, such as support vector machines (SVMs), may be useful in the identification of discriminative features. However, this method has yet to be applied to studies of RNA binding protein motifs. RESULTS: Applying the k-spectrum kernel to a support vector machine (SVM), we first verified the published binding sites of both HuR and TTP...

Decidual stromal cells (DSCs) are known to regulate trophoblast invasion via unveiled mechanism yet. And nucleotide-binding oligomerization domain-containing protein 1 (NOD1) may influence on this DSC-trophoblast interaction. We investigated the mechanism underlying the DSC-mediated regulation of trophoblast invasion and the effect of NOD1 on their cross talk. Using human primary DSCs, BeWo cell invasion was measured. Cytokine secretion and MAP kinase signaling were examined in DSCs following treatment with NOD1 agonist, Tri-DAP...

BACKGROUND: Ulcerative colitis (UC) harbours a high risk of UC-associated colorectal cancer (UCCC), which is important cause of morbidity and mortality in patients with inflammatory bowel disease. Overall Survival (OS) of patients with UCCC has not been addressed well in the literature. Thus, we compared oncologic outcome of UCCC and sporadic colorectal cancer (SCC) using propensity score matching analysis. METHODS: Propensity score matching was performed for 36 patients, a 1:1 matching method stratified into 18 in UCCC and 18 patients in SCC...

Propane is the major component of liquefied petroleum gas (LPG). Nowadays, the use of LPG is decreasing, and thus utilization of propane as a chemical feedstock is in need of development. An efficient biological conversion of propane to acetone using a methanotrophic whole cell as the biocatalyst was proposed and investigated. A bio-oxidation pathway of propane to acetone in Methylomonas sp. DH-1 was analyzed by gene expression profiling via RNA sequencing. Propane was oxidized to 2-propanol by particulate methane monooxygenase and subsequently to acetone by methanol dehydrogenases...

Rosai-Dorfman disease is a rare histiocytic proliferative disorder of unknown etiology typically characterized by cervical lymphadenopathy. Extranodal involvement often manifests in the head and neck region. We present a 10-year-old male who presented to our hospital with left epiphora from an aggressive paranasal mass invading the left orbit with osseous destruction. The mass was surgically biopsied and debulked with histopathological examination revealing Rosai-Dorfman disease. Although rarely found in the sinuses, Rosai-Dorfman disease should be considered when evaluating sinonasal masses...

Excitation emission matrix-parallel factor analysis (EEM-PARAFAC) and size exclusion chromatography (SEC) were utilized to explore the dynamics in extracellular polymeric substances (EPS), soluble microbial products (SMP), and effluent for the membrane bioreactors at two different organic loading rates (OLRs). Combination of three different fluorescent components explained the compositional changes of dissolved organic matter. The lower OLR resulted in a higher production of tryptophan-like component (C1) in EPS, while the opposite trends were found for the other two components (humic-like C2 and tyrosine-like C3), signifying the role of C1 in the endogenous condition...

Jin Hur, Byoung Wook Choi
While the etiology of ischemic stroke is heterogeneous, approximately 20%-40% of all stroke cases result from cardiac or aortic origin. Transesophageal echocardiography (TEE) has become the reference standard modality for the detection of potential sources of cerebral embolism. Because of the advances in computed tomographic (CT) technology, cardiac CT can be used in the evaluation of potential cardioembolic sources. During the past decade, cardiac CT has been tested and compared with TEE for the diagnosis of cardioembolic sources...

REVIEW
Seung Yun Lee, Sun Jun Hur
Bioactive peptides from food proteins exert beneficial effects on human health, such as angiotensin-converting enzyme (ACE) inhibition and antihypertensive activity. Several studies have reported that ACE-inhibitory peptides can come from animal products, marine organisms, and plants-derived by hydrolyzing enzymes such as pepsin, chymotrypsin, and trypsin-and microbial enzymes such as alcalase, thermolysin, flavourzyme, and proteinase K. Different ACE-inhibitory effects are closely related with different peptide sequences and molecular weights...

In neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), chronic activation of microglia contributes to disease progression. Activated microglia produce cytokines, chemokines, and other factors that normally serve to clear infection or damaged tissue either directly or through the recruitment of other immune cells. The molecular program driving this phenotype is classically linked to the transcription factor NF-κB and characterized by the upregulation of proinflammatory factors such as IL-1β, TNF-α, and IL-6...

Histone lysine acetylation is thought to play a role in regulating the balance between energy storage and energy expenditure. However, the epigenetic mechanisms by which food phytochemicals influence metabolic processes in the liver have not been thoroughly investigated. In this study, we investigated the effect of an ethanol extract of Capsella bursa-pastoris (ECB) on histone acetyltransferase (HAT) inhibition, and whether it could thereby attenuate lipid accumulation in vitro and in vivo. We observed that ECB inhibits HAT activity as assessed by colorimetric and autoradiography assay systems...

Inequalities between men and women are common and well-documented. Objective indexes show that men are better positioned than women in societal hierarchies-there is no single country in the world without a gender gap. In contrast, researchers have found that the women-are-wonderful effect-that women are evaluated more positively than men overall-is also common. Cross-cultural studies on gender equality reveal that the more gender egalitarian the society is, the less prevalent explicit gender stereotypes are...
