Abstract
The force-balanced state of magnetically confined plasmas heated up to 100 million degrees Celsius must be sustained long enough to achieve a burning-plasma state, such as in the case of ITER, a fusion reactor that promises a net energy gain. This force balance between the Lorentz force and the pressure gradient force, known as a plasma equilibrium, can be theoretically portrayed together with Maxwell's equations as plasmas are collections of charged particles. Nevertheless, identifying the plasma equilibrium in real time is challenging owing to its free-boundary and ill-posed conditions, which conventionally involves iterative numerical approach with a certain degree of subjective human decisions such as including or excluding certain magnetic measurements to achieve numerical convergence on the solution as well as to avoid unphysical solutions. Here, we introduce GS-DeepNet, which learns plasma equilibria through solely unsupervised learning, without using traditional numerical algorithms. GS-DeepNet includes two neural networks and teaches itself. One neural network generates a possible candidate of an equilibrium following Maxwell's equations and is taught by the other network satisfying the force balance under the equilibrium. Measurements constrain both networks. Our GS-DeepNet achieves reliable equilibria with uncertainties in contrast with existing methods, leading to possible better control of fusion-grade plasmas.

Abstract
BACKGROUND Childhood adversity has been linked to many indicators of shorter healthy lifespan, including earlier onset of disease and disability as well as early mortality. These observations suggest the hypothesis that childhood maltreatment may accelerate aging. OBJECTIVE To characterize the relationship between childhood maltreatment and accelerated biological aging in a prospective cohort of 357 individuals with documented cases of childhood maltreatment and 250 controls matched on demographic and socioeconomic factors. METHODS Cases were drawn from juvenile and adult court records from the years 1967 through 1971 in a large Midwest metropolitan geographic area. Cases were defined as having court-substantiated cases of childhood physical or sexual abuse, or neglect occurring at age 11 or younger. Controls were selected from the same schools and hospitals of birth and matched on age, sex, race, and approximate socioeconomic status. We compared biological aging in these two groups using two blood-chemistry algorithms, the Klemera-Doubal method Biological Age (KDM BA) and the PhenoAge. Algorithms were developed and validated in data from the National Health and Nutrition Examination Surveys (NHANES) using published methods and publicly available software. RESULTS Participants (55% women, 49% non-White) had mean age of 41 years (SD=4). Those with court substantiated childhood maltreatment history exhibited more advanced biological aging as compared with matched controls, although this difference was statistically different for only the KDM BA measure (KDM BA Cohen's D=0.20, 95% CI=[0.03,0.36], p = 0.02; PhenoAge Cohen's D=0.09 95% CI=[-0.08,0.25], p = 0.296). In subgroup analyses, maltreatment effect sizes were larger for women as compared to men and for White participants as compared to non-White participants, although these differences were not statistically significant at the α= 0.05 level. CONCLUSIONS AND RELEVANCE As of midlife, effects of childhood maltreatment on biological aging are small in magnitude but discernible. Interventions to treat psychological and behavioral sequelae of exposure to childhood maltreatment, including in midlife adults, have potential to protect survivors from excess burden of disease, disability, and mortality in later life.

Abstract
Abstract
Background
In recent years, there has been increasing recognition of a potentially-reversible, transient/ subacute form of constrictive pericarditis (CP). To date, studies have been small with lack of long-term longitudinal follow-up.
Purpose
We aimed to elucidate the causes and natural history of subacute CP.
Methods
Patients were included if (1) they had a diagnosis of CP, (2) had cardiac magnetic resonance (CMR) within 12 months of symptom onset with evidence of pericardial delayed enhancement/ inflammation (Figure) (3) received anti-inflammatory medications.
Results
A total of 78 individuals were included, comprising 61 men (78%) with a mean age of 59±14 years. Causes of subacute CP included idiopathic/ viral pericarditis (58%), post-pericardiotomy (29%), autoimmune (6%), radiation therapy (3%) and others (4%). After median follow-up of 4.4 years, 31 (40%) required pericardiectomy. There were no deaths.
Patients who underwent pericardiectomy had longer duration of symptoms at presentation [6 (4–9) vs. 3 (2–5) months, P<0.01], were more likely to be on diuretic therapy (87 vs. 45%, P<0.001), had lower ultra-sensitive C-reactive protein [4.4 (2.6–13.1) vs. 11.95 (1.8–61.55) mg/dl, P<0.001] and lower erythrocyte sedimentation rate [5 (2–10) vs. 25 (6–43 mm/hr), P=0.031] compared to those who were managed medically. There were no other significant differences in clinical characteristics or baseline anti-inflammatory therapy. The presence of elevated inflammatory markers (HR: 0.18; 95% CI: 0.06–0.58, P<0.01) was an independent predictor of freedom from pericardiectomy after adjustment for relevant clinical and imaging parameters.
Conclusions
We present the original observations of the largest cohort of patients with transient CP to date and demonstrate that increased inflammatory markers were independently associated with long-term freedom from pericardiectomy. Our results suggest that a trial of anti-inflammatory therapy in the setting of elevated inflammatory markers may be appropriate prior to referral for surgery given the possible reversibility.

Abstract
Abstract
Introduction
Right ventricular (RV) electrophysiologic and functional alterations related to sleep disordered breathing (SDB) in pulmonary arterial hypertension (PAH) are not well understood. We hypothesize an association between SDB and RV electrophysiological/functional measures in World Symposium of Pulmonary Hypertension (WSPH) Group 1 PAH.
Methods
The NHLBI multicenter PVDOMICS study (NCT02980887) enrolls patients with PAH undergoing a battery of assessments including home sleep apnea testing(NOX-T3, Carefusion®) or with historical sleep study data. Logistic(OR,95%CI) and linear(beta coefficients,95%CI) regression models adjusted for age, sex, race, body mass index (BMI, kg/m2), PAH medications, supplemental oxygen(O2), positive airway pressure(PAP) were used to assess associations of SDB(apnea hypopnea index,(AHI), ≥3% desaturations(hypopnea), percentage recording time with SaO2<90% (TRT<90%) with electrocardiographic measures: RV hypertrophy(RVH), right bundle branch block(RBBB), and right axis deviation(RAD), echocardiographically-derived RV systolic pressure(RVSP) and RV ejection fraction(RVEF) from cardiac MRI. Analyses were performed based on an overall significance level of 0.05, using SAS software (version 9.4, Cary, NC).
Results
The analysis consisted of 182 PAH participants with age: 52.5±13.9 years, 71.4% female, 88.9% Caucasian, BMI:30.3±7.8 kg/m2, RVEF: 37.3±11.6, and RVSP: 67.0±23.4. None of the electrocardiographic measures were associated with AHI and only RVH was significantly associated with TRT<90% (1.25:1.09,1.43),p=0.001. Although AHI was not associated with RVSP, a 10% increase in TRT<90% was associated with a 2.60mmHg increase in RVSP (2.60:1.44,3.76),p<0.001. Each 10-unit increase in AHI was associated with a 2.72% reduction of RVEF (-2.72:-4.89,-0.56),p=0.014, and each 10-unit increase in TRT<90% was associated with a 0.72% reduction of RVEF (-0.72:-1.38,-0.06),p=0.033.
Conclusion
We identify nocturnal hypoxia as a predictor of RV electrophysiological and functional alterations even after consideration of confounding factors. SDB as determined by AHI was also more so associated with reduced RVEF than hypoxia. Future mechanistic studies should focus on further elucidation of SDB and nocturnal hypoxia on pathogenesis of RV dysfunction in PAH.

Abstract
It is not completely clear whether "the lower, the better" cholesterol hypothesis for cardiovascular disease (CVD) and ischemic heart disease (IHD) can be applied to general populations with a low risk of heart disease mortality.We prospectively followed up 503,340 Koreans who participated in routine health checkups during 2002-2003 until 2013 via linkage to national mortality records.Nonlinear associations with total cholesterol (TC) were found: U-curves for overall CVD (I00-I99; nadir at 180-200 mg/dL) and a reverse-L-curve for IHD (I20-I25). Assuming a linear association in the lower range (<200 mg/dL), TC was inversely associated with CVD mortality (HR per 39 mg/dL [1 mmol/L] increase = 0.90). In the upper range (200-349 mg/dL), TC was positively associated with CVD mortality, largely due to IHD (HR = 1.19), especially acute myocardial infarction (HR = 1.23). The associations were generally similar in men versus women and in middle-aged (40-64 years) versus elderly (≥65 years) adults.TC levels of 180-200 mg/dL were associated with the lowest CVD mortality. Below 200 mg/dL, TC had no graded positive associations with IHD mortality. It remains unclear whether the lowest cholesterol levels are associated with the least mortality from CVD and IHD in Korean adults with a low risk of heart disease.

Abstract
Background:
The effect of drugs on ATP-binding cassette transporters, especially permeabilityglycoprotein
(P-gp), is an important consideration during new anti-cancer drug development.
Objective:
In this context, the effects of a newly synthesized artemisinin derivative, 10-(4-phenyl-1H-1,2,3-
triazol)-artemisinin (5a), were evaluated on P-gp expression and function.
Methods:
Reverse transcript polymerase chain reaction and immunoblotting techniques were used to determine
the effect of 5a on P-gp expression in LS174T cells. In addition, the ability of 5a to work as either a substrate or
an inhibitor of P-gp was investigated through different methods.
Results:
The results revealed that 5a acts as a novel P-gp inhibitor that dually suppresses the overexpression and
function of P-glycoprotein. Co-treatment of LS174T cell line, human colon adenocarcinoma cell line, with 5a and
paclitaxel recovered the anticancer effect of paclitaxel by controlling the acquired drug resistance pathway. The
overexpression of P-gp induced by rifampin and paclitaxel in a colorectal cell line was suppressed by 5a which
could be a novel inhibitory substrate inhibiting the transport of paclitaxel by P-gp.
Conclusion:
The results revealed that 5a can be classified as a type B P-gp inhibitor (with both substrate and
inhibitor activities) with an additional function of suppressing P-gp overexpression. The results might be clinically
useful in the development of anticancer drugs against cancers with multidrug resistance.
