Few studies have examined the relation between food consumption and related attitudes and dental pain among children. The objective of this study is to examine the associations of healthy and unhealthy food items, attitudes toward healthy food, and self-efficacy of eating healthy with dental pain among children. A cross-sectional analysis was performed using child survey data from the Texas Childhood Obesity Research Demonstration (TX CORD) project. Fifth-grade students ( n = 1,020) attending 33 elementary schools in Austin and Houston, Texas, completed the TX CORD Child Survey, a reliable and valid survey instrument focused on nutrition and physical activity behaviors. All nutrition questions ask about the number of times food and beverage items were consumed on the previous day. Dental pain was reported as mouth or tooth pain in the past 2 wk that made their mouth hurt so much that they could not sleep at night. Mixed-effects logistic regression models were used to test the association between 10 unhealthy food items, 9 healthy food items, 2 health attitudes, and self-efficacy with dental pain. All models controlled for sociodemographic variables. In total, 99 (9.7%) students reported dental pain. Dental pain was associated with intake of the following unhealthy items: soda, fruit juice, diet soda, frozen desserts, sweet rolls, candy, white rice/pasta, starchy vegetables, French fries/chips, and cereal (adjusted odds ratio [AOR], 1.27–1.81, P < 0.01). The intake of other vegetables (AOR, 1.56; P < 0.01), a healthy item, and the attitude that healthy food tastes good (AOR, 1.59; P = 0.04) were also positively associated with dental pain. The attitude of eating healthier leads to fewer health problems (AOR, 0.50) and self-efficacy for healthy eating (AOR, 0.44) were negatively associated with dental pain ( P < 0.01). Interventions should focus on improving oral health by reducing intake of unhealthy foods and educating children and families on the importance of diet as a means of reducing dental caries. Knowledge Transfer Statement: The results of this study can be used to inform researchers on potential food items and psychosocial measures to examine in low-income, minority populations for longitudinal research. These results would also be useful to educators who could incorporate oral health care and nutrition education into school curriculums.

AbstractAmmoniovoltaite, (NH4)2Fe2+5Fe3+3Al(SO4)12(H2O)18, is a new voltaite-group mineral. The mineral was discovered at the Severo-Kambalny (North-Kambalny) geothermal field, Kambalny volcanic ridge, Southern Kamchatka, Russia. Ammoniovoltaite forms at ~100°C around geothermal gas/steam vents in association with alunogen, tschermigite and pyrite. Crystals of ammoniovoltaite have euhedral habit, are up to 50 µm in size and grow on alunogen plates. Ammoniovoltaite is black with vitreous lustre, opaque, brittle and water-soluble. Neither cleavage nor parting is found, the fracture is conchoidal. The mineral is isotropic, with the refractive index n = 1.602(2) (589 nm). Infrared spectra contain an absorption band at 1433 cm–1 distinctive for the ammonium ion. The chemical composition is (iron content is given in accordance with Mössbauer data, H2O calculated from a crystal-structure refinement, wt.%): FeO 13.26, Fe2O3 11.58, MgO 2.33, ZnO 0.04, Al2O3 2.74, SO3 47.46, K2O 0.19, CaO 0.11, (NH4)2O 2.96, H2O 16.03, total 96.70.

The crystal structure has been refined to R1 = 0.031 and 0.030 on the basis of 1217 and 1462 unique reflections with I >2σ(I) collected at 100 K and room temperature, respectively. Ammoniovoltaite is the ammonium analogue of voltaite. The mineral is cubic, Fd$\bar{3}$c, a = 27.250(1) Å and V = 20234(3) Å3 (at 100 K); and a = 27.322(1) Å and V = 20396(3) Å3 (at RT), with Z = 16. The strongest lines of the powder X-ray diffraction pattern [d, Å (I, %) (hkl)] are: 9.67 (74) (022), 7.90 (56) (222), 5.58 (84) (422), 3.560 (100) (731), 3.418 (100) (008) and 2.8660 (37) (931). A brief review of ammonium minerals from various volcanically active geological environments is given.

ABSTRACTThe new mineral somersetite, has been found at Torr Works (‘Merehead quarry’) in Somerset, England, United Kingdom. Somersetite is green or white (typically it is similar visually to hydrocerussite-like minerals but with a mint-green tint), forms plates and subhedral grains up to 5 mm across and up to 2 mm thick. In bi-coloured crystals it forms very thin intergrowths with plumbonacrite. The empirical formula of somersetite is Pb8.00C5.00H4.00O20. The simplified formula is Pb8O(OH)4(CO3)5, which requires: PbO = 87.46, CO2= 10.78, H2O = 1.76, total 100.00 wt.%.The infrared spectrum of somersetite is similar to that of plumbonacrite and, to a lesser degree, hydrocerussite. Somersetite is hexagonal,P63/mmc,a= 5.2427(7),c= 40.624(6) Å,V= 967.0(3) Å3andZ= 2. The eight strongest reflections of the powder X-ray diffraction (XRD) pattern [d,Å(I)(hkl)] are: 4.308(33)(103), 4.148(25)(104), 3.581(40)(107), 3.390(100)(108), 3.206(55)(109), 2.625(78)(110), 2.544(98)(0.0.16) and 2.119(27)(1.0.17). The crystal structure was solved from single-crystal XRD data givingR1= 0.031. The structure of somersetite is unique and consists of the alternation of the electroneutral plumbonacrite-type [Pb5O(OH)2(CO3)3]0and hydrocerussite-type [Pb3(OH)2(CO3)2]0blocks separated by stereochemically active lone electron pairs on Pb2+. There are two blocks of each type per unit cell in the structure, which corresponds to the formula [Pb5O(OH)2(CO3)3][Pb3(OH)2(CO3)2] or Pb8O(OH)4(CO3)5in a simplified representation. The 2Dblocks are held together by weak Pb–O bonds and weak interactions between lone pairs.

AbstractTwo new minerals of the graftonite group, graftonite-(Mn), ideallyM(1)MnM(2),M(3)Fe2(PO4)2, and graftonite-(Ca), ideallyM(1)CaM(2),M(3)Fe2(PO4)2, were discovered in phosphate nodules of two beryl–columbite–phosphate pegmatites at Lutomia and Michałkowa, respectively, in the Góry Sowie Block, Lower Silesia, southwest Poland. Graftonite-(Mn) is pinkish brown, whereas graftonite-(Ca) shows more brownish colouration. Both minerals have a vitreous lustre, a good cleavage observed along (010) and irregular fracture; both are transparent and neither of them is fluorescent. They are brittle and have a Mohs hardness of ~5. The minerals are non-pleochroic, colourless in all orientations, biaxial (+), with mean refractive indices α = 1.710(2) and 1.690(2), β = 1.713(2) and 1.692(2), and γ = 1.725(2) and 1.710(5), respectively. With complete order of Ca at theM(1) site, the formulae of the holotype crystals areM(1)(Mn0.70Ca0.30)M(2),M(3)(Fe1.34Mn0.60Mg0.06Zn0.01)Σ3(PO4)2for graftonite-(Mn) andM(1)(Ca0.98Mn0.02)M(2),M(3)(Fe1.38Mn0.56Mg0.05)Σ3(PO4)2for graftonite-(Ca). Both crystal chemistry and crystal-structure refinement (R1= 2.34 and 1.63%, respectively) indicate that theM(1) site is occupied dominantly by Mn in graftonite-(Mn) and by Ca in graftonite-(Ca), and theM(2) andM(3) sites are occupied by Fe2+and Mn2+, with Fe2+dominant over Mn2+at the aggregateM(2) +M(3) sites. Graftonite-(Mn) and graftonite-(Ca) are isostructural with graftonite,M(1)FeM(2),M(3)Fe2(PO4)2(monoclinic system; space-group symmetryP21/c), with the unit-cell parametersa= 8.811(2) Å,b= 11.494(2) Å,c= 6.138(1) Å, β = 99.23(3)° and V = 613.5(4) Å3, anda= 8.792(2) Å,b= 11.743(2) Å,c= 6.169(1) Å, β = 99.35(3)° andV= 628.5(1) Å3, respectively. The densities calculated on the basis of molar weights and unit-cell volumes are 3.793 g/cm3for graftonite-(Mn) and 3.592 g/cm3for graftonite-(Ca). The eight strongest lines in powder X-ray diffraction patterns on the basis of single-crystal data are, respectively [d, Å,I(hkl)]: 2.874, 100, (230 + 040); 2.858, 79, (221); 3.506, 73, (130); 2.717, 79, ($\bar{3}$11); 2.952, 55, (131); 2.916, 53, ($\bar{1}$12); 2.899, 44, (300); 3.016, 35, ($\bar{1}$02); and 3.654, 100, (130); 2.979, 85, (221); 3.014, 77, (230); 3.042, 76, (040 +$\bar{1}$12); 2.834, 68, ($\bar{3}$11); 3.097, 57, (131); 3.133, 56, ($\bar{1}$02); 2.542, 30, (311). Both minerals are common primary phosphates in phosphate nodules, occurring as lamellar intergrowths with sarcopside ± triphylite/lithiophilite, products of exsolution from a (Li,Ca)-rich graftonite-like parent phase crystallized at high temperature from P-bearing hydrosaline melts.

Published: May 2018

The value of various computed tomography parameters for prognosis and risk stratification in acute pulmonary embolism is controversial. Our objective was to evaluate the impact of specific cardiovascular computed tomography pulmonary angiography parameters on short- and long-term clinical outcomes.We analysed radiological and clinical data of 1950 patients with acute pulmonary embolism who participated in an international randomised clinical trial on anticoagulants. Parameters included right/left ventricular ratio, septal bowing, cardiothoracic ratio, diameters of pulmonary trunk and aorta, and intrahepatic/azygos vein contrast medium backflow. Associations with mortality, recurrent venous thromboembolism (VTE), hospitalisation, bleeding and adverse events were assessed over the short term (1 week and 1 month) and long term (12 months).Pulmonary trunk enlargement was the only parameter significantly associated with mortality over both the short and long term (OR 4.18 (95% CI 1.04–16.76) at 1 week to OR 2.33 (95% CI 1.36–3.97) after 1 year), as well as with recurrent VTE and hospitalisation.Most of the evaluated radiological parameters do not have strong effects on the short- or long-term outcome in patients with acute pulmonary embolism. Only an enlarged pulmonary trunk diameter carries an increased risk of mortality and recurrent VTE up to 12 months, and can be used for risk stratification.
S-25OHD Is Associated With Hand Grip Strength and Myopathy at 5 Years in Girls: An Odense Child Cohort Study
Authors: Al-Jwadi Rada Faris , Jespersen Eva , Dalgård Christine , Bilenberg Niels , Christesen Henrik Thybo 
Published: May 2018

Abstract

Context
Severe vitamin D deficiency may lead to myopathy in adults. Little is known about vitamin D and muscle strength in children.

Objective
To test whether hand grip strength (HGS) in 5-year-old children is associated with serum 25-hydroxyvitamin D (S-25OHD).

Design
Observational study in the population-based Odense Child Cohort, Denmark. At 5 years, anthropometrics, body fat percentage by skinfold measurements, HGS (n = 881), and S-25OHD2+3 (n = 499) were obtained.

Results
Mean (SD) HGS was higher for boys compared with girls [8.76 (1.76) vs 8.1 (1.64) kg, P &lt; 0.001]. Mean (SD) 5-year S-25OHD was 70.7 (24.5) nmol/L. HGS was directly associated with height in girls and with weight (directly) and body fat percentage (inversely) in both sexes (P &lt; 0.01 for all). In girls, 5-year S-25OHD was associated with HGS, adjusting for height, weight, and body fat percentage [β = 0.011 (95% CI: 0.004; 0.019), P = 0.003]. S-25OHD ≥75 nmol/L was associated with higher HGS compared with values &lt;50 nmol/L [adjusted β = 0.783 (95% CI: 0.325; 1.241), P = 0.001]. The odds of having myopathy (HGS &lt;10th percentile) were reduced by approximately 70% for S-25OHD ≥50 vs &lt;50 nmol/L [adjusted OR: 0.310 (95% CI: 0.126; 0.762), P = 0.011]. No associations were seen for boys. Pregnancy or umbilical cord S-25OHD did not associate with 5-year HGS.

Conclusions
Five-year S-25OHD was independently associated with HGS and myopathy in girls but not in boys. Muscle strength may be dependent on vitamin D status even in the higher range in preschool girls. The sex difference remains unexplained.
Altered Asparagine and Glutamate Homeostasis Precede Coronary Artery Disease and Type 2 Diabetes
Authors: Ottosson Filip , Smith Einar , Melander Olle , Fernandez Céline 
Published: May 2018

Abstract

Context
Type 2 diabetes mellitus (T2DM) is accompanied by an increased risk for coronary artery disease (CAD), but the overlapping metabolic disturbances preceding both diseases are insufficiently described.

Objective
We hypothesized that alterations in metabolism occur years before clinical manifestation of T2DM and CAD and that these alterations are reflected in the plasma metabolome. We thus aimed to identify plasma metabolites that predict future T2DM and CAD.

Design
Through use of targeted liquid chromatography-mass spectrometry, 35 plasma metabolites (amino acid metabolites and acylcarnitines) were quantified in 1049 individuals without CAD and diabetes, drawn from a population sample of 5386 in the Malmö Preventive Project (mean age, 69.5 years; 31% women). The sample included 204 individuals who developed T2DM, 384 who developed CAD, and 496 who remained T2DM and CAD free during a mean follow-up of 6.1 years.

Results
In total, 16 metabolites were significantly associated with risk for developing T2DM according to logistic regression models. Glutamate (OR, 1.96; P = 5.4e-12) was the most strongly associated metabolite, followed by increased levels of branched-chain amino acids. Incident CAD was predicted by three metabolites: glutamate (OR, 1.28; P = 6.6e-4), histidine (OR, 0.76; P = 5.1e-4), and asparagine (OR, 0.80; P = 2.2e-3). Glutamate (OR, 1.48; P = 1.6e-8) and asparagine (OR, 0.75; P = 1.8e-5) were both associated with a composite endpoint of developing T2DM or CAD.

Conclusion
Several plasma metabolites were associated with incidence of T2DM and CAD; elevated glutamate and reduced asparagine levels were associated with both diseases. We thus discovered associations that might help shed additional light on why T2DM and CAD commonly co-occur.
When the Cherokee Became Indigenous:Cherokee Nation v. Georgiaand its Paradoxical Legalities
Authors: Bens Jonas 
Published: May 2018

AbstractWhen representatives of the Cherokee nation went to the US Supreme Court in 1831 to sue the state of Georgia, they initiated a paradoxical endeavor. They argued that they were a “foreign state,” but subjected themselves at the same time to the jurisdiction of the court of another state. In the course of this campaign, they transformed themselves from a political to a legal subject and took the position of what today would be called an “indigenous” community. The court translated the paradoxical formation of indigeneity—being legally incorporated and excluded at the same time—into the legal text of the judgment by inventing the contradictory phrase “domestic dependent nation.” Analyzing as an autoethnographic text the bill that the Cherokee nation presented to the Supreme Court, this essay investigates how the Cherokee’s indigeneity was produced in their interaction with the legal field of the (post)colonial state and how the paradoxical roots of indigeneity can serve as a starting point from which to rethink the native-settler relationship and the indigenous condition.
Material Enactments
Authors: Steinmetz Julia 
Published: May 2018

Abstract
Artists Cassils and Yishay Garbasz offer up a series of material enactments on and through the body that articulate a transformational aesthetics of trans subjectivity, one less concerned with representation than with actions and their indexical impacts. Both artists seek out, create, and become transformational objects for the alteration of self-experience. In so doing, each stretches and exceeds the limits of the identitarian, holding together the complexities of conflict and leaving room for the work of the unconscious in expansive imaginings of what it is to act as an artist in the sphere of the political while inhabiting the messy materiality of the body in the world. As viewers, we are drawn into complex dynamics of enacting the desires and fantasies of the psyche on, in, and through the materiality of the flesh.
The Hippo pathway effector Wwtr1 regulates cardiac wall maturation in zebrafish

Published: May 2018

ABSTRACT
Cardiac trabeculation is a highly regulated process that starts with the delamination of compact layer cardiomyocytes. The Hippo signaling pathway has been implicated in cardiac development but many questions remain. We have investigated the role of Wwtr1, a nuclear effector of the Hippo pathway, in zebrafish and find that its loss leads to reduced cardiac trabeculation. However, in mosaic animals, wwtr1−/− cardiomyocytes contribute more frequently than wwtr1+/− cardiomyocytes to the trabecular layer of wild-type hearts. To investigate this paradox, we examined the myocardial wall at early stages and found that compact layer cardiomyocytes in wwtr1−/− hearts exhibit disorganized cortical actin structure and abnormal cell-cell junctions. Accordingly, wild-type cardiomyocytes in mosaic mutant hearts contribute less frequently to the trabecular layer than when present in mosaic wild-type hearts, indicating that wwtr1−/− hearts are not able to support trabeculation. We also found that Nrg/Erbb2 signaling, which is required for trabeculation, could promote Wwtr1 nuclear export in cardiomyocytes. Altogether, these data suggest that Wwtr1 establishes the compact wall architecture necessary for trabeculation, and that Nrg/Erbb2 signaling negatively regulates its nuclear localization and therefore its activity.
A blood capillary plexus-derived population of progenitor cells contributes to genesis of the dermal lymphatic vasculature during embryonic development

ABSTRACT
Despite the essential role of the lymphatic vasculature in tissue homeostasis and disease, knowledge of the organ-specific origins of lymphatic endothelial progenitor cells remains limited. The assumption that most murine embryonic lymphatic endothelial cells (LECs) are venous derived has recently been challenged. Here, we show that the embryonic dermal blood capillary plexus constitutes an additional, local source of LECs that contributes to the formation of the dermal lymphatic vascular network. We describe a novel mechanism whereby rare PROX1-positive endothelial cells exit the capillary plexus in a Ccbe1-dependent manner to establish discrete LEC clusters. As development proceeds, these clusters expand and further contribute to the growing lymphatic system. Lineage tracing and analyses of Gata2-deficient mice confirmed that these clusters are endothelial in origin. Furthermore, ectopic expression of Vegfc in the vasculature increased the number of PROX1-positive progenitors within the capillary bed. Our work reveals a novel source of lymphatic endothelial progenitors employed during construction of the dermal lymphatic vasculature and demonstrates that the blood vasculature is likely to remain an ongoing source of LECs during organogenesis, raising the question of whether a similar mechanism operates during pathological lymphangiogenesis.
Psychological and Behavioral Responses to Interval and Continuous Exercise
Authors: STORK MATTHEW J. , GIBALA MARTIN J. , MARTIN GINIS KATHLEEN A. 
Published: May 2018

ABSTRACT

Purpose
To compare psychological responses to, and preferences for, moderate-intensity continuous training (MICT), high-intensity interval training (HIIT), and sprint interval training (SIT) among inactive adults; and to investigate the relationships between affect, enjoyment, exercise preferences, and subsequent exercise behavior over a 4-wk follow-up period.

Methods
Thirty inactive men and women (21.23 ± 3.81 yr), inexperienced with HIIT or SIT, completed three trials of cycle ergometer exercise in random order on separate days: MICT (45 min continuous; approximately 70% to 75% of HR maximum (HRmax)); HIIT (10 × 1 min bouts at approximately 85% to 90% HRmax with 1-min recovery periods); and SIT (3 × 20-s “all-out” sprints with 2-min recovery periods). Perceived exertion (RPE), affect, and arousal were measured throughout the trials and enjoyment was measured postexercise. Participants rank-ordered the protocols (1–3) according to preference and logged their exercise over a 4-wk follow-up.

Results
Despite elevated HR, RPE, and arousal during work periods (P’s < 0.05), and negative affect during HIIT and SIT, enjoyment and preferences for MICT, HIIT, and SIT were similar (P’s > 0.05). In-task affect was predictive of postexercise enjoyment for each type of exercise (r’s = 0.32 to 0.47; P’s < 0.05). In-task affect and postexercise enjoyment predicted preferences for HIIT and SIT (r
s’s = −0.34 to −0.61; P’s < 0.05), but not for MICT (P’s > 0.05), respectively. Over the follow-up, participants completed more MICT (M = 6.11 ± 4.12) than SIT sessions (M = 1.39 ± 1.85; P < 0.01, d = 1.34). Although participants tended to complete more sessions of MICT than HIIT (M = 3.54 ± 4.23; P = 0.16, d = 0.56), and more sessions of HIIT than SIT (P = 0.07, d = 0.60), differences were not significant. In-task affect predicted the number of sessions of MICT (r = 0.40; P < 0.05), but not HIIT or SIT (P’s > 0.05).

Conclusions
This study provides new evidence that a single session of HIIT and SIT can be as enjoyable and preferable as MICT among inactive individuals and that there may be differences in the exercise affect–behavior relationship between interval and continuous exercise.
