Abstract
Abstract
Background
For the improvement of efficacy in radiofrequency catheter ablation (RFCA) of pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF), fixed target Ablation Index (AI) value has been recommended regardless of individual and regional differences of left atrial wall thickness (LAWT).
Objective
To evaluate the association between LAWT and residual potential (RP) after first pass encirclement of PVI in AF patients receiving AI-guided PVI.
Method
A total of 116 patients (29% persistent AF) undergone AF RFCA using AI-guided PVI were included. Using SmartTouch catheter or SmartTouch SF catheter (Biosense Webster Inc., CA, US), point-by-point ablation was delivered at 30–40W on the anterior/roof segments and 25–30W on the posterior/inferior/carina segments. AI targets were 450 on the anterior/roof segments and 350 on the posterior/inferior/carina segments. After first encirclement of PVI was performed, RP was evaluated. LAWT was evaluated by 3-dimensional wall thickness map using computed tomographic images. LAWT values of ablation regions were graded by LAWT in each segment of PV antrum (Figure).
Results
Among a total of 1564 PV segments, RP was observed in 106 segments (6.8%). Left superior, inferior PV ridges and right superior PV roof segments were the most, second, and third thickest area among 14 PV segments (mean LAWT grade 5.09±1.08, 3.34±1.70, and 2.32±1.11, respectively). Mean LAWT grade was lower in segments with RP than those in without RP (2.74±1.80 vs. 2.07±1.28, p<0.001, Figure). In segments applied AI 450 (anterior/roof), segments with RP showed significantly thicker LAWT than those without RP (mean LAWT grade 3.65±2.01 vs. 2.57±1.56, p<0.001). In posterior/inferior/carina segments applied AI 350, there was no significant difference in mean LAWT between segments with and without RP (1.80±0.77 vs. 1.75±0.83, p=0.744).
Conclusion
Delivering same AI during PVI, thicker LAWT was associated with higher incidence of RP after first pass encirclement of PV in anterior/roof area. Tailored AI should be considered by LAWT to improve acute outcome of PVI.

Abstract
Abstract
Background
Bodyweight variability is a risk factor for atrial fibrillation (AF), but this has not been studied with a focus on patients with diabetes mellitus (DM).
Methods
A nationwide population-based cohort of 670,797 patients with type 2 DM from the Korean National Health Insurance Service database without a history of AF and with ≥3 measurements of body weight over a 5-year period were followed up for AF development. Intra-individual bodyweight variability was calculated using variability independent of mean (VIM), and high bodyweight variability was defined as the quintile with the highest variability with the lower four quintiles as reference.
Results
During a median of 7.0 years of follow-up, 22,019 patients (3.3%) were newly diagnosed with AF. Risk of incident AF was increased in those in the highest quintile of bodyweight variability, after adjustment for baseline body mass index (BMI), age, sex, lifestyle factors, comorbidities, number of oral anti-diabetic medication, insulin use, duration of DM, and fasting glucose (HR 1.16, 95% CI 1.12–1.20). High bodyweight variability was significantly associated with AF development regardless of baseline BMI group and direction of overall weight change. This association was stronger in subjects with lower BMI, those on insulin, and those with a DM duration of greater than 5 years.
Conclusions
High bodyweight variability was associated with AF development, independently of traditional cardiovascular risk factors and baseline BMI. This association was stronger in underweight patients and in advanced diabetic stage.

Abstract
Abstract
Introduction
There is a paucity of information about cardiovascular impacts related to the change of exercise habit after a new diagnosis of atrial fibrillation (AF). We aimed to investigate the influence of exercise on the risk of cardiovascular outcomes, such as ischemic stroke, heart failure (HF), and all-cause death, in patients with AF.
Methods
We included 66,692 patients with newly diagnosed AF (36.4% female, mean age 59.5 years, mean CHA2DS2-VASc 1.9) who underwent two serial health examinations before and after diagnosis of AF from 2010 to 2016, as provided by Korean National Health Insurance Corporation. The individuals self-reported a degree and frequency of exercise by questionnaires and doing vigorous physical activities ≥3 times/week or moderate physical activities ≥5 times/week was defined as a regular exercise group. The study population was divided into four categories according to the status of regular exercise before and after AF diagnosis: persistent non-exerciser (64.0%), new exerciser (13.4%), exercise drop-outs (12.5%), and exercise maintainer (10.1%). The primary outcomes were ischemic stroke, HF, and all-cause death during the follow-up.
Results
During a median 3.4 years follow-up, ischemic stroke, HF, and all-cause death occurred in 1905, 13112, and 2627 patients, respectively (incidence rates 8.5, 64.8, and 11.5 per 1,000 person-years, respectively). The change in exercise habits did not have a significant association with the risk of ischemic stroke (Figure 1). Regarding HF, those who newly initiated or maintained exercise after AF diagnosis showed a lower risk than those who do not exercise: hazard ratio, HR 0.93; 95% confidence interval, CI [0.88 to 0.98] and 0.90 [0.85 to 0.96] for each group, all p<0.001. Any experience of exercise involvement was associated with a lower risk of mortality than those without exercise: HR 0.76 [0.68–0.87] for new exerciser, 0.87 [0.78–0.98] for exercise drop-outs, and 0.62 [0.53–0.73] for exercise maintainer, all p<0.0001.
Conclusions
Patients who started or continued exercising after a new diagnosis of AF showed a lower risk of HF and mortality, but did not show an association with ischemic stroke. Regular exercise might improve the cardiovascular outcomes in patients with newly diagnosed AF.

Abstract
ETS variant 1 (ETV1) is an oncogenic transcription factor. However, its role in colorectal cancer has remained understudied. The present study demonstrated that ETV1 downregulation led to reduced HCT116 colorectal cancer cell growth and clonogenic activity. Furthermore, the ETV1 mRNA levels were enhanced in colorectal tumors and were associated with disease severity. In addition, ETV1 directly bound to Jumonji C domain-containing (JMJD) 1A, a histone demethylase known to promote colon cancer. ETV1 and JMJD1A, but not a catalytically inactive mutant thereof, cooperated in inducing the matrix metalloproteinase (MMP)1 gene promoter that was similar to the cooperation between ETV1 and another histone demethylase, JMJD2A. RNA-sequencing revealed multiple potential ETV1 target genes in HCT116 cells, including the FOXQ1 and TBX6 transcription factor genes. Moreover, JMJD1A co-regulated FOXQ1 and other ETV1 target genes, but not TBX6, whereas JMJD2A downregulation had no impact on FOXQ1 as well as TBX6 transcription. Accordingly, the FOXQ1 gene promoter was stimulated by ETV1 and JMJD1A in a cooperative manner, and both ETV1 and JMJD1A bound to the FOXQ1 promoter. Notably, the overexpression of FOXQ1 partially reversed the growth inhibitory effects of ETV1 ablation on HCT116 cells, whereas TBX6 impaired HCT116 cell growth and may thereby dampen the oncogenic activity of ETV1. The latter also revealed for the first time, to the best of our knowledge, a potential tumor suppressive function of TBX6. Taken together, the present study uncovered a ETV1/JMJD1A-FOXQ1 axis that may drive colorectal tumorigenesis.

Abstract
OBJECTIVE To examine the concordance rate of non-chromosomal congenital malformations in twin pairs based on zygosity. DESIGN Retrospective cohort study. SETTING A tertiary hospital in Korea. POPULATION Twin pairs born at Seoul National University Hospital between 2001 and 2019. METHODS Congenital malformations were diagnosed by postnatal workups of neonates or autopsy in cases of stillborn infants. Zygosity was confirmed by sex, chorionicity and DNA analysis. MAIN OUTCOME MEASURES Concordance rate of congenital malformations in twin pairs based on zygosity. RESULTS In total, 3386 twin pairs were included. The risk of a congenital malformation in the index twin increased significantly if the co-twin had the congenital malformation, and the concordance rate was higher in monozygotic (MZ) than in dizygotic (DZ) twins (37.04 versus 16.77, P < 0.001). An increased risk of a congenital malformation in the presence of the same congenital malformation in the co-twin was observed only for malformations of the nervous system, eye/ear/face/neck, circulatory system, cleft lip/palate, genital organs, urinary system and musculoskeletal system. Significantly higher concordance rates in MZ than in DZ twin pairs were observed only for the nervous system (40.00 versus 0.00, P < 0.001), circulatory system (32.97 versus 19.74, P = 0.021), cleft lip/palate (44.44 versus 0.00, P = 0.017) and urinary system (22.22 versus 0.00, P = 0.004), whereas significant differences were not found for the genital organs or musculoskeletal system. CONCLUSIONS Monozygotic twins had higher concordance rates than DZ twins only in specific organ systems. It may be speculated that nervous system, circulatory system, cleft lip/palate and urinary system are primarily genetically affected. TWEETABLE ABSTRACT Monozygotic twins had higher concordance rates than dizygotic twins only in specific organ systems.

Abstract
BACKGROUND Molar Incisor Malformation (MIM) or Molar Root Incisor malformation (MRIM) is a recently discovered root malformation with constricted pulp and abnormally located furcation presented in permanent first molars and sometimes incisors. CASE REPORT Two cases that feature MIM are presented with the description of the characteristic tooth form, clinical/radiographic examination, medical history, the supposed aetiology, treatment procedure and results at the 2-year follow-up. Conservative endodontic treatment was performed in both cases, furcation perforation and canal perforation were filled with MTA (Mineral Trioxide Aggregate), and a good prognosis was observed after 2 years of follow-up. Furthermore, recommended treatment options are discussed to provide a more appropriate treatment for the patients. CONCLUSION Patients with MIM need to be treated at the right time to avoid severe infection and other problems. Early diagnosis with appropriate treatment is more likely to lead to a more favourable prognosis.

Abstract
Osteoporosis is a systemic skeletal disease characterized by low bone mass and micro-architectural deterioration of bone tissue, with a consequent increase in bone fragility and fracture susceptibility. In an aged society with increased life expectancy, the incidence rate of osteoporosis is also rapidly increasing. Inadequate nutrition may negatively influence bone metabolism. Recently, many studies have investigated the functionality of milk-derived exosomes, which play important roles in cell-to-cell communication. However, there are few reports of how milk-derived exosomes influence osteoblast proliferation and differentiation. Here, we determined whether bovine colostrum-derived exosomes promote anti-osteoporosis in vitro and in vivo. Tartrate-resistant acid phosphatase-stained cells were significantly inhibited in Raw264.7 cells treated with exosomes, indicating reduced osteoclast differentiation. We induced osteoporosis in mice using glucocorticoid pellets after orally administering exosomes for 2 mo. Interestingly, the bone mineral density of exosome-fed mouse groups was significantly improved compared with the glucocorticoid-induced osteoporosis group without exosome treatment. In addition, Lactobacillus were decreased in the gut microbiota community of osteoporosis-induced mice, but the gut microbiota community composition was effectively restored by exosome intake. Taken together, we propose that exosomes isolated from bovine colostrum could be a potential candidate for osteoporosis prevention, bone remodeling improvement, and inhibition of bone resorption. To our knowledge, this is the first time that a protective effect of milk exosomes against osteoporosis has been demonstrated in vivo. Our results strongly suggest that bovine colostrum exosomes might be used as a prophylaxis to prevent the onset of osteoporosis. Indeed, our results offer promising alternative strategies in the nutritional management of age-related bone complications.

Abstract
Light can be strongly confined in subwavelength spatial regions through the interaction with plasmons, the collective electronic modes appearing in metals and semiconductors. This confinement, which is particularly important in the terahertz spectral region, amplifies light-matter interaction and provides a powerful mechanism for efficiently generating nonlinear optical phenomena. These effects are particularly relevant in graphene and topological insulators, where massless Dirac fermions show a naturally nonlinear optical behavior in the terahertz range. The strong interaction scenario has been considered so far from the point of view of light. In this Letter, we investigate instead the effect of strong interaction on the plasmon itself. In particular, we will show that Dirac plasmons in Bi_{2}Se_{3} topological insulator are strongly renormalized when excited by high-intensity terahertz radiation by displaying a huge red-shift down to 60% of its characteristic frequency. This opens the road towards tunable terahertz nonlinear optical devices based on topological insulators.

Abstract
Abstract
Introduction
Literature suggests that stress may play an important role in sleep disturbance. Individuals with higher stress levels often showed hyperarousal to stressful events, possibly leading to sleep disturbance. Hyperarousal is also one of features of stress-related sleep disturbance. Here, we examined the extent to which stress levels interact with neural activity in response to sleep-related information to predict sleep disturbance.
Methods
Forty eight healthy adults (26 females, age = 35.7 ± 10.5) without sleep disorders based on nocturnal polysomnography participated in this study. They were viewing sleep-related pictures (e.g., bedroom and sunset) and non-sleep related, neutral pictures (e.g., kitchen and landscape) during fMRI scanning. They also completed questionnaires assessing stress levels and sleep disturbance using Life Experience Survey (LES) and Pittsburgh Sleep Quality Index (PSQI), respectively. Activity in response to sleep-related pictures compared to neutral pictures was extracted from our region-of-interest (ROI), the anterior insula, and entered into our moderation models. The SPSS macro PROCESS (Hayes, 2013) was used to conduct moderation analyses. Given a significant correlation between age and PSQI scores, age was included as a covariate.
Results
Our moderation analyses showed that interactions between stress levels and anterior insula response to sleep-related pictures significantly predicted sleep disturbance. Simple slope analyses showed that at higher anterior insula response, higher stress levels were associated with greater sleep disturbance, but at lower anterior insula response, stress was not significantly associated with sleep disturbance. These results indicate that individuals with high levels of stress were more likely to experience sleep disturbance if they showed greater anterior insula response to sleep-related pictures (i.e., hyperarousal in response to sleep-related information).
Conclusion
The current findings suggest that interactions between stress levels and neural substrates of hyperarousal, particularly the anterior insula, may play a critical role in sleep disturbance.

Abstract
Abstract
Introduction
Shift work is known to have a negative impact on a wide range of health problems such as sleep disturbance, cognitive impairment, and emotional disorders (e.g., anxiety and depression). It is important to understand underlying mechanisms for negative impact of shift work on health problems. This study aimed to investigate psychological and neural mechanisms associated with shift work.
Methods
Thirty six shift workers (28 females, age = 29.9 ± 7.4) and 35 non-shift workers (20 females, age = 30.5 ± 5.5) participated in this study. They were performing the word Stroop task during fMRI scanning. This task included sleep-related words and negative words to investigate neural substrates associated with sleep-related information and emotional information processing. Neutral words were included as control stimuli. The participants also completed questionnaires assessing sleep-related problems such as Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale, and emotion-related problems such as Beck Depression Inventory and Beck Anxiety Inventory. Two-sample t-tests were conducted to find group differences in self-report measures and neural response to sleep-related words and negative words compared to neutral words.
Results
Relative to non-shift workers, shift workers showed greater sleep disturbance (i.e., higher PSQI), but they did not show any evidence of emotion-related problems. Shift workers also demonstrated greater neural response to negative words (vs. neutral words) in several prefrontal regions (e.g., dorsal anterior cingulate cortex and dorsolateral prefrontal cortex), anterior insula and caudate compared to non-shift workers. However, shift workers did not show significantly different neural response to sleep-related words (vs. neutral words) compared to non-shift workers.
Conclusion
The result from this study provides supporting evidence that shift work is associated with subjective sleep disturbance. Shift workers’ heightened neural response to negative information may reflect their increased sensitivity to negative information, that may contribute to sleep disturbance.

Abstract
MyoD family inhibitor (MDFI) and MDFI domain-containing (MDFIC) are homologous proteins known to regulate myogenic transcription factors. Hitherto, their role in cancer is unknown. We discovered that MDFI is up- and MDFIC downregulated in colorectal tumors. Mirroring these different expression patterns, MDFI stimulated and MDFIC inhibited growth of HCT116 colorectal cancer cells. Further, MDFI and MDFIC interacted with Jumonji C domain-containing (JMJD) 1 A, a histone demethylase and epigenetic regulator involved in colorectal cancer. JMJD1A influenced transcription of several genes that were also regulated by MDFI or MDFIC. Notably, the HIC1 tumor suppressor gene was stimulated by JMJD1A and MDFIC, but not by MDFI, and HIC1 overexpression phenocopied the growth suppressive effects of MDFIC in HCT116 cells. Similar to colorectal cancer, MDFI was up- and MDFIC downregulated in breast, ovarian and prostate cancer, but both were overexpressed in brain, gastric and pancreatic tumors that implies MDFIC to also promote tumorigenesis in certain tissues. Altogether, our data suggest a tumor modulating function for MDFI and MDFIC in colorectal and other cancers that may involve their interaction with JMJD1A and a MDFIC→HIC1 axis.

Abstract
We report on the first measurement of the charmed baryon Λ_{c}^{±} production at midrapidity (|y|<1) in Au+Au collisions at sqrt[s_{NN}]=200 GeV collected by the STAR experiment at the Relativistic Heavy Ion Collider. The Λ_{c}/D^{0} [denoting (Λ_{c}^{+}+Λ_{c}^{-})/(D^{0}+D[over ¯]^{0})] yield ratio is measured to be 1.08±0.16 (stat)±0.26 (sys) in the 0%-20% most central Au+Au collisions for the transverse momentum (p_{T}) range 3<p_{T}<6 GeV/c. This is significantly larger than the pythia model calculations for p+p collisions. The measured Λ_{c}/D^{0} ratio, as a function of p_{T} and collision centrality, is comparable to the baryon-to-meson ratios for light and strange hadrons in Au+Au collisions. Model calculations including coalescence hadronization for charmed baryon and meson formation reproduce the features of our measured Λ_{c}/D^{0} ratio.

Abstract
Offspring adrenal function may be negatively affected in utero by maternal stressors such as microbial infection. Maternal supplementation with immunomodulatory compounds such as omega-3 polyunsaturated fatty acids (n-3 PUFA) may help minimize the adverse effects of maternal stress on fetal hypothalamic-pituitary-adrenal development and improve offspring health. Presently, n-3 PUFA sources are primarily fish-based, but n-3 PUFA microalgae (AL) may be an alternative. Previously, it was determined that maternal AL or fish oil (FO) supplementation to sows, in addition to maternal stress induced by Escherichia coli lipopolysaccharide (LPS) challenge appeared to have a greater influence on the stress response of male offspring compared to females. To further elaborate on these findings, this study assessed the effects of maternal AL or FO supplementation combined with a maternal LPS challenge on adrenal gene expression in male offspring fed a nursery diet containing low-quality protein sources. Forty-eight sows were fed gestation diets starting on gestation day (gd) 75 containing either 3.12% AL, 3.1% FO, or a control diet containing 1.89% corn oil. On gd 112, half the sows in each treatment were administered 10 μg/kg LPS i.m. Piglets were weaned at 21 days of age onto a common low-quality plant-based protein diet, and one week after weaning, four piglets per sow were administered 40 μg/kg LPS i.m. Two hours later, the piglets were euthanized to obtain adrenal tissue, and total RNA was extracted to carry out transcriptome analysis using the Affymetrix GeneChip WT Plus assay and subsequent validation by real-time PCR. Analysis revealed that adrenal steroidogenesis, fatty acid metabolism and immune function were significantly influenced by maternal diet and stress. Increased expression of immune-related genes including lymphocyte antigen 96, TLR-2 and NF-κB suggests that maternal AL supplementation may increase offspring sensitivity to inflammation after weaning. Decreased expression of lymphocyte antigen 96 in male offspring from sows receiving maternal LPS challenge also suggests a possible role of maternal stress in diminishing the offspring immune response to immune stress challenge. Increased expression of the genes encoding the 11BHSD2 enzyme in offspring from sows fed FO may also reduce the magnitude of the stress response. These data provide insight to the immune and metabolic mechanisms that may be influenced by maternal diet and stress. Expression of adrenal steroidogenesis genes were influenced by maternal treatment. Expression of lipid metabolism genes and immune function genes were enriched. Maternal algae supplementation may increase offspring sensitivity to inflammation. Maternal stress may reduce the offspring immune response to immune challenges. Maternal fish oil supplementation may reduce the offspring stress response.

Abstract
We investigated whether oral health, represented by missing teeth, was associated with an increased risk of cardiovascular disease, including myocardial infarction (MI), heart failure (HF), stroke, and all-cause mortality. Subjects who underwent routine dental examinations and health checkups provided by the Korean National Health Insurance from 2007 to 2008 ( n = 4,440,970) were followed up for incident MI, HF, stroke, and death until 2016. During follow-up of 7.56 y, 68,063 (1.5%) subjects died, and 31,868 (0.7%) were admitted for MI, 22,637 (0.5%) for HF, and 30,941 (0.7%) for stroke. Cardiovascular events and mortality increased in proportion to tooth loss. Tooth loss was an independent risk factor for cardiovascular events after multivariable analysis adjusted for cardiovascular risk, behavioral, and income factors. Each missing tooth was associated with an approximately 1% increase in MI (HR, 1.010; 95% CI, 1.007 to 1.014), 1.5% increase in HF (HR, 1.016; 95% CI, 1.013 to 1.019) and stroke (HR, 1.015; 95% CI, 1.012 to 1.018), and 2% increase in mortality (HR, 1.022; 95% CI, 1.020 to 1.023). Having ≥5 missing teeth substantially increased risk for cardiovascular outcomes, and even a small number of missing teeth (1 to 4) was associated with an increased risk for MI, stroke, and death. This association was consistent in subgroup analyses and especially strong among the younger subjects (age <65 y) and those with periodontitis. In this large Korean nationwide cohort study, we found that tooth loss showed a dose-dependent association with incident MI, HF, ischemic stroke, and all-cause death and was a good predictor of cardiovascular outcome. In clinical practice, the number of missing teeth can aid physicians in discriminating patients with a higher cardiovascular risk.

Abstract
Hardware artificial neural network (ANN) systems with high density synapse array devices can perform massive parallel computing for pattern recognition with low power consumption. To implement a neuromorphic system with on-chip training capability, we need to develop an ideal synapse device with various device requirements, such as scalability, MLC characteristics, low power operation, data retention, and symmetric/linear conductance changes under potentiation/depression modes. Although various devices have been proposed for synapse applications, they have limitations for application in neuromorphic systems. In this paper, we will cover various RRAM synapse devices, such as filamentary switching RRAM (HfOx, TaOx, Cu-CBRAM) and analog RRAM devices, based on interface resistive switching (Pr0.7Ca0.3MnOx and TiOx) and ferroelectric polarization (HfZrOx). By optimizing potentiation/depression conditions, we could improve the conductance linearity and MLC characteristics of filamentary synapse devices. Interface RRAM has better MLC characteristics with limited retention and conductance linearity. By controlling the reactivity of metal electrodes and the oxygen concentration in oxides, we can modulate the synapse characteristics. Metal-Ferroelectric-Insulator-Semiconductor (MFIS) FET devices exhibit good retention characteristics and analog memory characteristics due to polarization. Based on various synapse device characteristics, we have estimated the pattern recognition accuracy of MNIST handwritten digits and CIFAR-10 datasets. We have confirmed that synapse device characteristics directly affect the pattern recognition accuracy of ANNs. In order to simultaneously satisfy all the requirements of synapse devices, it is necessary to develop new technology capable of controlling the movement of oxygen vacancies and metal ions at the atomic scale. Considering the limited synapse characteristics of current 2-terminal RRAM devices, hardware ANNs capable of only off-chip training can be constructed by optimizing the current RRAM devices by limiting the bit number. A 3-terminal synapse device or a device based on a new operation principle should be developed as an alternative for on-chip training applications.

Abstract
Tumor suppressor ARID1A, a subunit of the chromatin remodeling complex SWI/SNF, regulates cell cycle progression, interacts with the tumor suppressor TP53, and prevents genomic instability. In addition, ARID1A has been shown to foster resistance to cancer therapy. By promoting non-homologous end joining (NHEJ), ARID1A enhances DNA repair. Consequently, ARID1A has been proposed as a promising therapeutic target to sensitize cancer cells to chemotherapy and radiation. Here, we report that ARID1A is regulated by human antigen R (HuR), an RNA-binding protein that is highly expressed in a wide range of cancers and enables resistance to chemotherapy and radiation. Our results indicate that HuR binds ARID1A mRNA, thereby increasing its stability in breast cancer cells. We further find that ARID1A expression suppresses the accumulation of DNA double-strand breaks (DSBs) caused by radiation and can rescue the loss of radioresistance triggered by HuR inhibition, suggesting that ARID1A plays an important role in HuR-driven resistance to radiation. Taken together, our work shows that HuR and ARID1A form an important regulatory axis in radiation resistance that can be targeted to improve radiotherapy in breast cancer patients.

Abstract
We report the first measurement of rapidity-odd directed flow (v_{1}) for D^{0} and D^{0}[over ¯] mesons at midrapidity (|y|<0.8) in Au+Au collisions at sqrt[s_{NN}]=200 GeV using the STAR detector at the Relativistic Heavy Ion Collider. In 10-80% Au+Au collisions, the slope of the v_{1} rapidity dependence (dv_{1}/dy), averaged over D^{0} and D^{0}[over ¯] mesons, is -0.080±0.017(stat)±0.016(syst) for transverse momentum p_{T} above 1.5 GeV/c. The absolute value of D^{0} meson dv_{1}/dy is about 25 times larger than that for charged kaons, with 3.4σ significance. These data give a unique insight into the initial tilt of the produced matter, and offer constraints on the geometric and transport parameters of the hot QCD medium created in relativistic heavy-ion collisions.

Abstract
Abstract
Background
High levels of lipids and lipid variability are established risk factors for atherosclerotic cardiovascular disease. We investigated their roles in the development of atrial fibrillation (AF). This is the largest cohort study yet on the association between lipid levels and AF, and the first study on the association between lipid variability and AF.
Methods
A nationwide population-based cohort of 3,828,652 adults (mean age 43.9 years) from the Korean National Health Insurance Service database without prevalent AF, not on lipid-lowering medication, and with at least 3 measurements of each lipid parameter at 1–2 year intervals over a 4-year period were included. Total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) were measured, and lipid variability was calculated using variability independent of mean. The cohort was divided into quartiles by baseline lipid levels and lipid variability, and followed up for incident AF.
Results
During median 3.4 years of follow-up, AF was newly diagnosed in 13,240 (0.35%). AF development was inversely associated with TC and LDL-C levels (for top vs. bottom quartile; TC, hazard ratio [HR] 0.76, 95% confidence interval [95% CI] 0.72–0.80); LDL-C, HR 0.78, 95% CI 0.74–0.82) in both sexes, and with TG levels in men (HR 0.85, 95% CI 0.80–0.90). Meanwhile, AF development was associated with higher LDL-C and HDL-C variability (for top vs. bottom quartile; LDL-C, HR 1.16, 95% CI 1.10–1.22; HDL-C, HR 1.08, 95% CI 1.03–1.14) in both sexes, and with TC variability in men (HR 1.16, 95% CI 1.10–1.22).
Conclusions
Lower cholesterol levels (TC, LDL-C) and higher cholesterol variability (LDL-C, HDL-C) were associated with higher risk for AF. Low TG levels and high TC variability were also associated with AF incidence in men. These findings support the “cholesterol paradox” in AF, and suggest that cholesterol variability is also a risk factor for AF development.
