PURPOSE: Preimplantation genetic screening (PGS) and assessment of mitochondrial content (MC) are current methods for selection of the best embryos for transfer. Studies suggest that time-lapse morphokinetics (TLM) may also be helpful for selecting embryos more likely to implant. In our study, we sought to examine the relationship between TLM parameters and MC to determine if they could be used adjunctively in embryo selection. We also examined the relationship between MC with ploidy and blastulation...

A subset of benign (WHO grade I) skull base meningiomas show early progression/recurrence (P/R) in the first years after surgical resection. Besides, complete surgical resection may be difficult to achieve safely in skull base meningiomas due to complex neurovascular structures. The one main challenge in the treatment of skull base meningiomas is to determine factors that correlate with P/R. We retrospectively investigated the preoperative CT and MR imaging features for the prediction of P/R in skull base meningiomas, with emphasis on quantitative ADC values...

Alginate and polycaprolactone (PCL) were coelectrospun using a dual-jet system to prepare composite nanofibers in defined ratios, and hence both chemical properties and hydrophobicity of scaffolds can be manipulated. These nanofibers were applied in gene immobilization: positively charged polyethyleneimine (PEI)/DNA polyplexes were adsorbed onto anionic alginate fibers, and the higher ratios of alginate resulted in the more immobilized nonviral vectors. Through the incorporation of PCL, biocompatibility of scaffolds was highly improved...

Due to the complex profile of atherosclerotic risk factors, an integrated analysis of a specific individual is difficult. Endothelial function reflects a composite of various risk factors, and may be used as an optimal tool to estimate the overall atherosclerotic risk. In this study, we investigated the value of digital Reactive Hyperemia Index (RHI) in an actual population with multiple atherosclerotic risk factors or coronary artery disease (CAD). A total of 417 patients from the Seoul National University Boramae Medical Center RHI registry were enrolled in this study...

BACKGROUND: With an increasing interest in the use of theta burst stimulation (TBS) as a cognitive enhancer and a potential therapeutic tool for psychiatric disorders, there is a need to identify optimal parameters of TBS in the prefrontal cortex. OBJECTIVE/HYPOTHESIS: This study examined the effect of two blocks of prefrontal intermittent TBS (iTBS) on cortical reactivity and working memory performance, compared to one block of iTBS and sham stimulation. We hypothesized that greater cortical effects would be obtained with two blocks of iTBS...

Desmosome components are frequently mutated in cardiac and cutaneous disorders in animals and humans and enhanced inflammation is a common feature of these diseases. Previous studies showed that inhibitor of Apoptosis Stimulating p53 Protein (iASPP) regulates desmosome integrity at cell-cell junctions and transcription in the nucleus, and its deficiency causes cardiocutaneous disorder in mice, cattle, and humans. As iASPP is a ubiquitously expressed shuttling protein with multiple functions, a key question is whether the observed cardiocutaneous phenotypes are caused by loss of a cell autonomous role of iASPP in cardiomyocytes and keratinocytes specifically or by a loss of iASPP in other cell types such as immune cells...

The ankle-brachial index (ABI) is a reliable diagnostic examination for peripheral arterial occlusive disease (PAOD). We previously reported CHADS2 score was significantly correlated with PAOD. However, the association between CHA2DS2-VASc score and ABI < 0.9 is not evaluated in the literature. The aim of the present study was to investigate whether CHA2DS2-VASc score has a strong association with PAOD. We enrolled 1482 patients in this study. PAOD was defined as ABI < 0.9 in either leg. Vascular disease in CHA2DS2-VASc score was modified as vascular disease except PAOD...

Cyclin-dependent kinase 5 (Cdk5) is a key neuronal kinase that is upregulated during inflammation, and can subsequently modulate sensitivity to nociceptive stimuli. We conducted an in silico screen for Cdk5 phosphorylation sites within proteins whose expression was enriched in nociceptors and identified the chemo-responsive ion channel Transient Receptor Potential Ankyrin 1 (TRPA1) as a possible Cdk5 substrate. Immunoprecipitated full length TRPA1 was shown to be phosphorylated by Cdk5 and this interaction was blocked by TFP5, an inhibitor that prevents activation of Cdk5...

Bone homeostasis is regulated by communication between bone-forming mature osteoblasts (mOBs) and bone-resorptive mature osteoclasts (mOCs). However, the spatial-temporal relationship and mode of interaction in vivo remain elusive. Here we show, by using an intravital imaging technique, that mOB and mOC functions are regulated via direct cell-cell contact between these cell types. The mOBs and mOCs mainly occupy discrete territories in the steady state, although direct cell-cell contact is detected in spatiotemporally limited areas...

Type 2 diabetes in Asia occurs largely in the absence of obesity. The metabolically-obese normal-weight (MONW) phenotype refers to lean subjects with metabolic dysfunction that is typically observed in people with obesity, and is associated with increased risk for diabetes. Previous studies evaluated MONW subjects who had greater BMI or total body fat than respective control groups, making interpretation of the results difficult. We evaluated insulin sensitivity (hyperinsulinemic-euglycemic clamp), insulin secretion (mixed meal with oral minimal modeling), intra-abdominal, muscle, and liver fat contents (magnetic resonance), and fasting and postprandial glucose and insulin concentrations in 18 MONW subjects and 18 metabolically-healthy controls matched for age (43{plus minus}3 and 40{plus minus}3 y; P=0...

Acute lung injury (ALI) and the acute respiratory distress syndrome (ARDS) are high-mortality and life-threatening diseases that are associated with neutrophil activation and accumulation within lung tissue. Emerging evidence indicates that neutrophil-platelet aggregates (NPAs) at sites of injury increases acute inflammation and contributes to the development of ALI. Even though numerous studies have increased our understanding of the pathophysiology of ALI, there is still a lack of innovative and useful treatments that reduce mortality, emphasizing that there is an urgent need for novel treatment strategies...
