Abstract
We reconstruct the two-dimensional (2D) matter distributions in 20 high-mass galaxy clusters selected from the CLASH survey by using the new approach of performing a joint weak gravitational lensing analysis of 2D shear and azimuthally averaged magnification measurements. This combination allows for a complete analysis of the field, effectively breaking the mass-sheet degeneracy. In a Bayesian framework, we simultaneously constrain the mass profile and morphology of each individual cluster, assuming an elliptical Navarro–Frenk–White halo characterized by the mass, concentration, projected axis ratio, and position angle (PA) of the projected major axis. We find that spherical mass estimates of the clusters from azimuthally averaged weak-lensing measurements in previous work are in excellent agreement with our results from a full 2D analysis. Combining all 20 clusters in our sample, we detect the elliptical shape of weak-lensing halos at the 5σ significance level within a scale of 2

. The median projected axis ratio is 0.67 ± 0.07 at a virial mass of

, which is in agreement with theoretical predictions from recent numerical simulations of the standard collisionless cold dark matter model. We also study misalignment statistics of the brightest cluster galaxy, X-ray, thermal Sunyaev–Zel’dovich effect, and strong-lensing morphologies with respect to the weak-lensing signal. Among the three baryonic tracers studied here, we find that the X-ray morphology is best aligned with the weak-lensing mass distribution, with a median misalignment angle of

. We also conduct a stacked quadrupole shear analysis of the 20 clusters assuming that the X-ray major axis is aligned with that of the projected mass distribution. This yields a consistent axis ratio of 0.67 ± 0.10, suggesting again a tight alignment between the intracluster gas and dark matter.

Objective
The aim of this study was to investigate the effects of transmucosal administration of thyroxine on the tooth movement and osteoclastic activity in Beagle dogs.

Materials and Methods
Eight Beagles were randomly divided into control group (n = 4) and thyroxine group (4-week group, n = 2 and 8-week group, n = 2). Buttons were bonded on the labial surfaces of the second premolar and anchorage teeth. Nickel-titanium closed-coil springs were connected. In the thyroxine group, thyroxine tablets were bonded to the hooks attached to the second premolar.

Results
The mean rate of orthodontic tooth movement (OTM) in the thyroxine group was slightly higher than that in the control group. Microscopic evaluation showed that the number of osteoclasts in the thyroxine group significantly increased.

Conclusion
The protocol for transmucosal administration of thyroxine could not significantly accelerate OTM. An increase in the number of osteoclasts was observed through microscopic evaluation during the 4th week.

Abstract. Organic aerosol (OA) represents a large fraction of submicron aerosols in the
megacity of Beijing, yet long-term characterization of its sources and
variations is very limited. Here we present an analysis of in situ
measurements of OA in submicrometer particles with an aerosol chemical
speciation monitor (ACSM) for 2 years from July 2011 to May 2013. The sources
of OA are analyzed with a multilinear engine (ME-2) by constraining three
primary OA factors including fossil-fuel-related OA (FFOA), cooking OA (COA),
and biomass burning OA (BBOA). Two secondary OAs (SOA), representing a less
oxidized oxygenated OA (LO-OOA) and a more oxidized (MO-OOA), are identified
during all seasons. The monthly average concentration OA varied from 13.6 to
46.7 µg m−3 with a strong seasonal pattern that is usually
highest in winter and lowest in summer. FFOA and BBOA show similarly
pronounced seasonal variations with much higher concentrations and
contributions in winter due to enhanced coal combustion and biomass burning
emissions. The contribution of COA to OA, however, is relatively stable
(10–15 %) across different seasons, yet presents significantly higher
values at low relative humidity levels (RH < 30 %),
highlighting the important role of COA during clean periods. The two SOA
factors present very different seasonal variations. The pronounced
enhancement of LO-OOA concentrations in winter indicates that emissions from
combustion-related primary emissions could be a considerable source of SOA
under low-temperature (T) conditions. Comparatively, MO-OOA shows high
concentrations consistently at high RH levels across different T levels,
and the contribution of MO-OOA to OA is different seasonally with lower
values occurring more in winter (30–34 %) than other seasons
(47–64 %). Overall, SOA (= LO-OOA + MO-OOA) dominates OA
composition during all seasons by contributing 52–64 % of the total OA
mass in the heating season and 65–75 % in non-heating seasons. The
variations in OA composition as a function of OA mass loading further
illustrate the dominant role of SOA in OA across different mass loading
scenarios during all seasons. However, we also observed a large increase in
FFOA associated with a corresponding decrease in MO-OOA during periods with
high OA mass loadings in the heating season, illustrating an enhanced role of
coal combustion emissions during highly polluted episodes. Potential source
contribution function analysis further shows that the transport from the
regions located to the south and southwest of Beijing within ∼ 250 km
can contribute substantially to high FFOA and BBOA concentrations in the
heating season.
Detection and variability of combustion-derived vapor in an urban basin

Published: June 2018

Abstract. Water emitted during combustion may comprise a significant portion of ambient humidity (>  10 %) in urban areas, where combustion emissions are strongly focused in space and time. Stable water vapor isotopes can be used to apportion measured humidity values between atmospherically transported and combustion-derived water vapor, as combustion-derived vapor possesses an unusually negative deuterium excess value (d-excess, d  =  δ2H − 8δ18O). We investigated the relationship between the d-excess of atmospheric vapor, ambient CO2 concentrations, and atmospheric stability across four winters in Salt Lake City, Utah. We found a robust inverse relationship between CO2 excess above background and d-excess on sub-diurnal to seasonal timescales, which was most prominent during periods of strong atmospheric stability that occur during Salt Lake City winter. Using a Keeling-style mixing model approach, and assuming a molar ratio of H2O to CO2 in emissions of 1.5, we estimated the d-excess of combustion-derived vapor in Salt Lake City to be −179 ± 17 ‰, consistent with the upper limit of theoretical estimates. Based on this estimate, we calculate that vapor from fossil fuel combustion often represents 5–10 % of total urban humidity, with a maximum estimate of 16.7 %, consistent with prior estimates for Salt Lake City. Moreover, our analysis highlights that changes in the observed d-excess during periods of high atmospheric stability cannot be explained without a vapor source possessing a strongly negative d-excess value. Further refinements in this humidity apportionment method, most notably empirical validation of the d-excess of combustion vapor or improvements in the estimation of the background d-excess value in the absence of combustion, can yield more certain estimates of the impacts of fossil fuel combustion on urban humidity and meteorology.
Technical note: A low-cost albedometer for snow and ice measurements – theoretical results and application on a tropical mountain in Bolivia

Published: June 2018

Abstract. This study presents a new instrument called a low-cost albedometer (LCA)
composed of two illuminance sensors that are used to measure in situ
incident and reflected illuminance values on a daily timescale. The ratio
between reflected vs. incident illuminances is called the albedo index and can be compared with actual albedo values. Due to the shape of the
sensor, the direct radiation for zenith angles ranging from 55 to 90∘
is not measured. The spectral response of the LCA varies with the solar
irradiance wavelengths within the range 0.26 to 1.195 µm, and the
LCA detects 85 % of the total spectral solar irradiance for clear sky
conditions. We first consider the theoretical results obtained for 10
different ice and snow surfaces with clear sky and cloudy sky incident solar
irradiance that show that the LCA spectral response may be responsible for an
overestimation of the theoretical albedo values by roughly 9 % at most.
Then, the LCA values are compared with two “traditional” albedometers, which are CM3
pyranometers (Kipp &amp; Zonen), in the shortwave
domain from 0.305 to 2.800 µm over a 1-year measurement period
(2013) for two sites in a tropical mountainous catchment in Bolivia. One site
is located on the Zongo Glacier (i.e., snow and ice surfaces) and the second
one is found on the crest of the lateral moraine (bare soil and snow
surfaces), which present a horizontal surface and a sky view factor of 0.98.
The results, at daily time steps (256 days), given by the LCA are in good
agreement with the classic albedo measurements taken with pyranometers with
R2=0.83 (RMSD = 0.10) and R2=0.92 (RMSD = 0.08) for the
Zongo Glacier and the right-hand side lateral moraine, respectively. This
demonstrates that our system performs well and thus provides relevant
opportunities to document spatiotemporal changes in the surface albedo from
direct observations at the scale of an entire catchment at a low cost.
Finally, during the period from September 2015 to June 2016, direct
observations were collected with 15 LCAs on the Zongo Glacier and
successfully compared with LANDSAT images showing the surface conditions of
the glacier (i.e., snow or ice). This comparison illustrates the
efficiency of this system to monitor the daily time step changes in the
snow and ice coverage distributed on the glacier. Despite the limits imposed by
the angle view restrictions, the LCA can be used between 45∘ N and
45∘ S during the ablation season (spring and summer) when the melt
rate related to the albedo is the most important.
Ecotoxicity of disinfectant benzalkonium chloride and its mixture with antineoplastic drug 5-fluorouracil towards algaPseudokirchneriella subcapitata
Authors: Elersek Tina , Ženko Maja , Filipič Metka 
Published: June 2018

BackgroundBenzalkonium chloride (BAC) is one of the most common ingredients of the disinfectants. It is commonly detected in surface and wastewaters where it can interact with the residues of pharmaceuticals that are also common wastewater pollutants. Among the latter, the residues of antineoplastic drugs are of particular concern as recent studies showed that they can induce adverse effect in aquatic organisms at environmentally relevant concentrations.MethodsEcotoxicity of BAC as an individual compound and in a binary mixture with an antineoplastic drug 5-fluorouracil (5-FU) was determined towards algaPseudokirchneriella subcapitata,a representative of primary producers.The toxicity of the BAC+5-FU binary mixture was predicted by the two basic models: concentration addition (CA) and independent action (IA), and compared to the experimentally determined toxicity. Additionally combination index (CI) was calculated to determine the type of interaction.ResultsAfter 72 h exposure to BAC a concentration dependent growth inhibition ofP. subcapitatawas observed with an EC500.255 mg/L. Comparing the predicted no effect concentration to the measured concentrations in the surface waters indicate that BAC at current applications and occurrence in aquatic environment may affect algal populations. The measured toxicity of the mixture was higher from the predicted and calculated CI confirmed synergistic effect on the inhibition of algal growth, at least at EC50concentration. The observed synergism may have impact on the overall toxicity of wastewaters, whereas it is less likely for general environments because the concentrations of 5-FU are several orders of magnitude lower from its predicted no effect concentration.DiscussionThese results indicate that combined effects of mixtures of disinfectants and antineoplastic drugs should be considered in particular when dealing with environmental risk assessment as well as the management of municipal and hospital wastewaters.
Beta-blocker use and cardiovascular event risk in patients with heart failure with preserved ejection fraction

Published: June 2018

AbstractTo assess whether beta-blocker use is associated with cardiovascular events and mortality in patients with heart failure with preserved ejection fraction (HFpEF), this study analyzed the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial data using Cox proportional hazard models. Adjusted HRs for composite cardiovascular events in all patients and in patients without previous MI were significantly higher for those on beta-blockers than for those not on beta-blockers (Hazard ratio [HR] for all patients 1.23, 95% confidence interval [95% CI] 1.02–1.49; HR for patients without previous MI 1.35, 95% CI 1.08–1.70), whereas that for patients with previous MI was not significantly different (HR 1.06, 95% CI 0.74–1.54). Additionally, cardiovascular event risk in propensity score-matched patients without previous MI was significantly higher in those on beta-blockers than in those not on beta-blockers. Risks of all-cause death, major cardiovascular events, and heart failure hospitalization were significantly higher in those on beta-blockers than in those not on beta-blockers. Beta-blocker use in HFpEF patients, particularly those without previous MI, was associated with increased risk of unfavorable cardiovascular events.

ABSTRACT
Female sex pheromone of a clearwing moth Nokona feralis (Leech) (Lepidoptera: Sesiidae), a pest of kiwifruit, was identified to be a 7:3 mixture of (3E,13Z)-3,13-octadecadienyl acetate (E3,Z13-18:OAc) and (3E,13Z)-3,13-octadecadien-1-ol (E3,Z13-18:OH) by GC-EAD and GC/MS analyses. Males were attracted to wide-range mixtures of E3,Z13-18:OAc and E3,Z13-18:OH, and a 7:3 mixture of those two compounds strongly attracted the males in the field.

Published: June 2018

AbstractSeveral peptides in clinical use are derived from non-ribosomal peptide synthetases (NRPS). In these systems multiple NRPS subunits interact with each other in a specific linear order mediated by docking domains (DDs) to synthesize well-defined peptide products. In contrast to these classical NRPSs, the subunits of rhabdopeptide/xenortide producing NRPSs can act iteratively and in different order resulting in libraries of peptide products. In order to define the structural and thermodynamic basis for their unusual interaction patterns, we determined the structures of all N-terminal DDs (NDDs) as well as of an NDD-CDD complex and characterized all putative DD interactions thermodynamically for one such system. Key amino acid residues for DD interactions were identified that upon their exchange not only changed the DD affinity but also resulted in rationally predictable changes in peptide production. A simple set of ‘recognition rules’ for DD interactions was identified that also operates in other megasynthase complexes.

AbstractThe role of the microbiome in health and disease involves complex networks of host genetics, genomics, microbes and environment. Identifying the mechanisms of these interactions has remained challenging. Systems genetics in the laboratory mouse enables data-driven discovery of network components and mechanisms of host-microbial interactions underlying multiple disease phenotypes. To examine the interplay among the whole host genome, transcriptome and microbiome, we mapped quantitative trait loci and correlated the abundance of cecal mRNA, luminal microflora, physiology and behavior in incipient strains of the highly diverse Collaborative Cross mouse population. The relationships that are extracted can be tested experimentally to ascribe causality among host and microbe in behavior and physiology, providing insight into disease. Application of this strategy in the Collaborative Cross population revealed experimentally validated mechanisms of microbial involvement in models of autism, inflammatory bowel disease and sleep disorder.eTOC BlurbHost genetic diversity provides a variable selection environment and physiological context for microbiota and their interaction with host physiology.
