Characterization of FANCL variants observed in patient cancer cells
Authors: Frost Mark G. , Mazloumi Aboukheili Amir Mahdi , Toth Rachel , Walden Helen
Published: May 2020

Fanconi Anemia (FA) is a rare genetic disorder characterized by developmental defects, bone marrow failure and high predisposition to cancer. The FA DNA repair pathway is required in humans to coordinate repair of DNA interstrand cross-links. The central event in the activation of the pathway is the monoubiquitination of FANCD2 and FANCI by the E2-E3 pair, Ube2T-FANCL, with the central UBC-RWD (URD) domain of FANCL recognizing the substrates. Whole genome sequencing studies of cancer cells from patients identified point mutations in the FANCL URD domain. We analysed 17 such variants of FANCL, including known substrate binding mutants (W212A, W214A and L248A, F252A, L254A, I265A), a FA mutation (R221C) and 14 cancer-associated mutations (F110S, I136V, L149V, L154S, A192G, E215Q, E217K, R221W, T224K, M247V, F252L, N270K, V287G, E289Q) through recombinant expression analysis, thermal shift assay, interaction with FANCD2, in vitro ubiquitination activity, and cellular sensitivity to an interstrand cross-linking agent. We find that the FANCL mutations I136V, L154S, W212A and L214A, R221W, R221C, and V287G are destabilizing, with N270K and E289Q destabilizing the C-terminal helices of the URD domain. The hydrophobic patch mutant (L248A, F252A, L254A, I265A), along with mutations E217K, T224K, and M247V, cause defects in the catalytic function of FANCL. This highlights the C-terminal lobe of the FANCL URD domain as important for the activity and function of FANCL. These mutations which affect the fold and activity of FANCL may contribute to tumorigenesis in these non-FA cancer patients, and this implicates FA genes in general cancer progression.
Associations between PHACTR1 gene polymorphisms and pulse pressure in Chinese Han population
Authors: Gu Kunfang , Zhang Yue , Sun Ke , Jiang Xiubo
Published: May 2020

A genome-wide association study (GWAS) in Chinese twins was performed to explore associations between genes and pulse pressure (PP) in 2012, and detected a suggestive association in the phosphatase and actin regulator 1 (PHACTR1) gene on chromosome 6p24.1 (rs1223397, P=1.04e−07). The purpose of the present study was to investigate associations of PHACTR1 gene polymorphisms with PP in a Chinese population. We recruited 347 subjects with PP ≥ 65 mmHg as cases and 359 subjects with 30 ≤ PP ≤ 45 mmHg as controls. Seven single nucleotide polymorphisms (SNPs) in the PHACTR1 gene were genotyped. Logistic regression was performed to explore associations between SNPs and PP in codominant, additive, dominant, recessive and overdominant models. The Pearson’s χ2 test was applied to assess the relationships of haplotypes and PP. The A allele of rs9349379 had a positive effect on high PP. Multivariate logistic regression analysis showed that rs9349379 was significantly related to high PP in codominant [AA vs GG, 2.255 (1.132–4.492)], additive [GG vs GA vs AA, 1.368 (1.049–1.783)] and recessive [AA vs GA + GG, 2.062 (1.051–4.045)] models. The positive association between rs499818 and high PP was significant in codominant [AA vs GG, 3.483 (1.044–11.613)] and recessive [AA vs GG + GA, 3.716 (1.119–12.339)] models. No significant association of haplotypes with PP was detected. There was no significant interaction between six SNPs without strong linkage. In conclusion, the present study presents that rs9349379 and rs499818 in the PHACTR1 gene were significantly associated with PP in Chinese population. Future research should be conducted to confirm them.
Mechanisms and roles of mitochondrial localisation and dynamics in neuronal function
Authors: Seager Richard , Lee Laura , Henley Jeremy M. , Wilkinson Kevin A.
Published: May 2020

Neurons are highly polarised, complex and incredibly energy intensive cells, and their demand for ATP during neuronal transmission is primarily met by oxidative phosphorylation by mitochondria. Thus, maintaining the health and efficient function of mitochondria is vital for neuronal integrity, viability and synaptic activity. Mitochondria do not exist in isolation, but constantly undergo cycles of fusion and fission, and are actively transported around the neuron to sites of high energy demand. Intriguingly, axonal and dendritic mitochondria exhibit different morphologies. In axons mitochondria are small and sparse whereas in dendrites they are larger and more densely packed. The transport mechanisms and mitochondrial dynamics that underlie these differences, and their functional implications, have been the focus of concerted investigation. Moreover, it is now clear that deficiencies in mitochondrial dynamics can be a primary factor in many neurodegenerative diseases. Here, we review the role that mitochondrial dynamics play in neuronal function, how these processes support synaptic transmission and how mitochondrial dysfunction is implicated in neurodegenerative disease.
The Effect of SPEAK OUT! and The LOUD Crowd on Dysarthria Due to Parkinson's Disease
Authors: Behrman Alison , Cody Jennifer , Elandary Samantha , Flom Peter , Chitnis Shilpa
Published: May 2020

Purpose

SPEAK OUT! and The LOUD Crowd is a standardized speech therapy program of 12 individual treatments combined with ongoing weekly group sessions for individuals with dysarthria due to Parkinson's disease (PD). The premise of this program is that individuals with PD must rely on goal-directed basal ganglia–cortical circuits to compensate for deficits in habitual, automatic control. The purpose of this study was to assess the outcome of this therapy program.

Method

Forty individuals with idiopathic PD received SPEAK OUT! in 12 individual 40-min sessions 3 times per week for 4 consecutive weeks and also participated in The LOUD Crowd. Assessments were conducted 3 times at baseline and then within 1 and 6 weeks after completion of the individual SPEAK OUT! sessions. Twenty-five adults without communication disorders were assessed on the same schedule. Acoustic outcome measures were mean intensity from reading and monologue, the prosody measures of standard deviation of intensity and frequency from reading and monologue, and the voice quality measure of cepstral peak prominence from reading. Patient perception of voice was also assessed with the Voice-Related Quality of Life.

Results

Posttherapy, mean intensity was greater and variation of frequency was larger in reading and monologue, while variation in intensity was larger in monologue but unchanged in reading. Cepstral peak prominence and Voice-Related Quality of Life scores were significantly higher (improved) after therapy.

Conclusion

These data contribute to evidence of the effectiveness of this program for hypokinetic dysarthria secondary to idiopathic PD and thus inform clinical practice in the selection among treatment options.
Discovery of a jet from the single HAe/Be star HD 100546
Authors: Schneider P. C. , Dougados C. , Whelan E. T. , Eislöffel J. , Günther H. M. , Huélamo N. , Mendigutía I. , Oudmaijer R. D. , Beck Tracy L.
Published: May 2020

Young accreting stars drive outflows that collimate into jets, which can be seen hundreds of au from their driving sources. Accretion and outflow activity cease with system age, and it is believed that magneto-centrifugally launched disk winds are critical agents in regulating accretion through the protoplanetary disk. Protostellar jets are well studied in classical T Tauri stars (M⋆ ≲ 2 M⊙), while few nearby (d ≲ 150 pc) intermediate-mass stars (M⋆ = 2−10 M⊙), known as Herbig Ae/Be stars, have detected jets. We report VLT/MUSE observations of the Herbig Ae/Be star HD 100546 and the discovery of a protostellar jet. The jet is similar in appearance to jets driven by low-mass stars and compares well with the jet of HD 163296, the only other known optical jet from a nearby Herbig Ae/Be star. We derive a (one-sided) mass-loss rate in the jet of log Ṁjet ∼ −9.5 (in M⊙ yr−1) and a ratio of outflow to accretion of roughly 3 × 10−3, which is lower than that of CTTS jets. The discovery of the HD 100546 jet is particularly interesting because the protoplanetary disk around HD 100546 shows a large radial gap, spiral structure, and might host a protoplanetary system. A bar-like structure previously seen in Hα with VLT/SPHERE shares the jet position angle, likely represents the base of the jet, and suggests a jet-launching region within about 2 au. We conclude that the evolution of the disk at radii beyond a few au does not affect the ability of the system to launch jets.
Parameterisations of interior properties of rocky planets
Authors: Noack Lena , Lasbleis Marine
Published: May 2020

Context.Observations of Earth-sized exoplanets are mostly limited to information on their masses and radii. Simple mass-radius relationships have been developed for scaled-up versions of Earth or other planetary bodies such as Mercury and Ganymede, as well as for one-material spheres made of pure water(-ice), silicates, or iron. However, they do not allow a thorough investigation of composition influences and thermal state on a planet’s interior structure and properties.

Aims.In this work, we investigate the structure of a rocky planet shortly after formation and at later stages of thermal evolution assuming the planet is differentiated into a metal core and a rocky mantle (consisting of Earth-like minerals, but with a variable iron content).

Methods.We derived possible initial temperature profiles after the accretion and magma ocean solidification. We then developed parameterisations for the thermodynamic properties inside the core depending on planet mass, composition, and thermal state.

Results.We provide the community with robust scaling laws for the interior structure, temperature profiles, and core- and mantle-averaged thermodynamic properties for planets composed of Earth’s main minerals but with variable compositions of iron and silicates.

Conclusions.The scaling laws make it possible to investigate variations in thermodynamic properties for different interior thermal states in a multitude of applications such as deriving mass-radius scaling laws or estimating magnetic field evolution and core crystallisation for rocky exoplanets.
Contribution of the ageing effect to the observed asymmetry of interplanetary magnetic clouds
Authors: Démoulin P. , Dasso S. , Lanabere V. , Janvier M.
Published: May 2020

Context.Large magnetic structures are launched away from the Sun during solar eruptions. They are observed as (interplanetary) coronal mass ejections (ICMEs or CMEs) with coronal and heliospheric imagers. A fraction of them are observed in situ as magnetic clouds (MCs). Fitting these structures properly with a model requires a better understanding of their evolution.

Aims.In situ measurements are made locally when the spacecraft trajectory crosses the magnetic configuration. These observations are taken for different elements of plasma and at different times, and are therefore biased by the expansion of the magnetic configuration. This ageing effect means that stronger magnetic fields are measured at the front than at the rear of MCs. This asymmetry is often present in MC data. However, the question is whether the observed asymmetry can be explained quantitatively from the expansion alone.

Methods.Based on self-similar expansion, we derived a method for estimating the expansion rate from the observed plasma velocity. We next corrected the observed magnetic field and the spatial coordinate along the spacecraft trajectory for the ageing effect. This provided corrected data as in the case when the MC internal structure were observed at the same time.

Results.We apply the method to 90 best-observed MCs near Earth (1995–2012). The ageing effect is the main source of the observed magnetic asymmetry for only 28% of the MCs. After correcting for the ageing effect, the asymmetry is almost symmetrically distributed between MCs with a stronger magnetic field at the front and those at the rear of MCs.

Conclusions.The proposed method can efficiently remove the ageing bias within in situ data of MCs, and more generally, of ICMEs. This allows us to analyse the data with a spatial coordinate, such as in models or remote-sensing observations.
Lagerungstherapie bei bindegewebigen Gelenkkontrakturen am Beispiel der Frozen Shoulder
Authors: Schomacher Jochen
Published: May 2020

Passive Mobilisation wirkt allgemein schmerzlindernd und kann daher auch bei schmerzhaften Bewegungseinschränkungen der Frozen Shoulder effektiv sein. Die
schwache bis moderate Evidenz in der Literatur ist diesbezüglich unklar. Bei der im Krankheitsverlauf der Frozen Shoulder entstehenden bindegewebigen
Gelenkkontraktur ist die manuelle Mobilisation unwirksam.

Der vorliegende Beitrag erläutert anhand einer narrativen Literaturanalyse die Ursachen einer bindegewebigen Gelenkkontraktur und stellt Behandlungsmöglichkeiten
vor. Die tägliche stundenlange Behandlungsdauer scheint hierbei eine entscheidende Rolle zu spielen. Einige Studien erreichten dies mit der Schienenbehandlung.
Die praktikable Alternative der Lagerung wird als Teil eines Behandlungsprogramms bei bindegewebigen Gelenkkontrakturen vorgestellt.

Den Belastungen des Schulranzens mit gezielter Anspannung entgegenwirken
Authors: Eichmann Björn , Erhardt Tobias , Kirchberger Joris
Published: May 2020

Immer mehr Kinder leiden an Rückenschmerzen, in der Altersklasse von 11–17 Jahren sogar mehr als jedes 4. Kind. Als Ursache wird unter anderem der Schulranzen
angenommen.

Diese randomisierte, kontrollierte Studie mit 59 Kindern untersuchte, ob sich die Schmerzen durch ein Rückentraining reduzieren lassen. Die beiden
Interventionsgruppen führten ein- bzw. zweimal pro Woche ein Rückentraining durch, die 3. Gruppe diente als Kontrollgruppe. Es zeigte sich kein signifikanter
Zusammenhang zwischen dem Gewicht des Schulranzens und dem Auftreten von Rückenschmerzen. Die Interventionsgruppen verbesserten im Vergleich zur Kontrollgruppe
jedoch signifikant ihre Koordination.

Die Studienergebnisse liefern Denkanstöße für die Gesundheitspädagogik an Grundschulen.

The aim of this paper is to summarize the results of a consensus process and a European webinar of the two societies, European Association of Societies of Aesthetic Surgery (EASAPS) and the European Society of Plastic, Reconstructive and Aesthetic Societies (ESPRAS) on what is considered safe practice based on the scientific knowledge we have today. This review of the current situations gives considerations which have to be taken into account when getting back to work in plastic surgery with COVID-19 in Europe. At all times, one should be familiar the local and regional infection rates in the community, with particular emphasis on the emergence of second and third waves of the pandemic. Due to the fast-evolving nature of the COVID-19 pandemic the recommendations aim to be rather considerations than fixed guidelines and might need to be revised in near future.

Published: May 2020

A range of treatment modalities are available for the treatment of different oral diseases.The frequent use and misuse of currently available therapeutic agents has led to the evolution of increased incidence of adverse effects and development of resistant strains. Hence the search for an alternative option continues. Medicinal plants have been used as traditional treatment agents since ages. Garlic (Allium sativum) has been recognized for a number of therapeutic properties in the traditional system of medicine. Allium sativum is traditionally employed to treat infection, colds, diabetes, heart disease, and a host of other disorders. Clinically, it has been evaluated for lowering blood pressure, cholesterol, and glucose concentration, as well as for the prevention of arteriosclerosis and cancer. It is well known for its potent anti- inflammatory, anti- oxidant, anti-bacterial and antimutagenic properties. This article aims to review the efficacy of garlic in maintaining oral health in particular and overall health in general.
A COMPARATIVE STUDY OF TERBINAFINE ETHOSOMAL FORMULATIONS: A NOVEL APPROACH
Authors: R. Narayana Charyulu , Satveek Mehta , M. Harish N. , Patil Amit B.
Published: May 2020

The present research work aimed at the impact of reduced vesicular size on the characteristics of ethosomes by comparing with the regular vesicular size of ethosomes as topical drug delivery vehicle to achieve optimal localized drug concentration and reduced dose frequency of the Terbinafine hydrochloride (TH), an antifungal drug. Oral use of TH contraindicated resulting from sever side effect, thus topical administration is recommended. Commercially available TH creams, lotions and sprays, have limitation of relatively short residual period at target site. The entrapment of drug in vesicles improves localization, solubility and availability of drug at the site; resulting in reduction of the dose. Ethosomes containing drug were prepared by employing higher concentration of alcohol in the form of hydroalcoholic or hydroglycolic phospholipid. Sonicated and unsonicated ethosomes were investigated for shape, particle size, and entrapment efficiency. Electronic microscope investigation not only revealed, vital evidence for presence of phospholipid vesicles in TH ethosomal systems but also displayed greater uniformity in size and shape of sonicated ethosomes than unsonicated ethosomes. Furthermore, the Comparative investigation was carried out for ex vivo skin permeation, ex vivo drug release and entrapment efficiency studies. Drug release followed zero order release rate kinetics. Drug accumulation study showed more than 19.01 % of drug was deposited into skin by sonicated ethosomal formulation as compared to 2.57 % by unsonicated ethosomal formulation. Sonicated and unsonicated ethosomes were found stable at refrigeration and room temperature conditions during stability studies. Drug accumulation studies in deep skin strata was found to be comparatively greater in sonicated ethosomes, which indicates higher localized drug and that in turn reduces dose frequency.

Perylene Bisimide Cyclophanes: Structure–Property Relationships upon Variation of the Cavity Size
Authors: Rühe Jessica , Bialas David , Spenst Peter , Krause Ana-Maria , Würthner Frank
Published: May 2020

Five cyclophanes composed of two perylene bisimide (PBI) dyes and various CH2–arylene–CH2 linker units were synthesized. PM6-D3H4 geometry-optimized structures and a single crystal for one of these cyclophanes reveal well-defined distances between the two coplanar PBI units in these cyclophanes, spanning the range from 5.0 to 12.5 Å. UV/vis absorption spectra reveal a redistribution of oscillator strength of the vibronic bands due to a H-type exciton coupling even for the cyclophane with the largest interchromophoric distance. A quantitative evaluation according to the Kasha–Spano theory affords exciton coupling strengths ranging from 64 cm−1 for the largest cyclophane up to 333 cm−1 for the smallest one and a surprisingly good fit to the cubic interchromophoric distance in the framework of the point-dipole approximation. Interchromophoric interaction is also noticed in fluorescence lifetimes that are significantly increased for all five cyclophanes as expected for H-coupled chromophores due to a decrease of the radiative rate. For the three largest cyclophanes with interchromophoric distances of >9 Å, fluorescence quantum yields remain high in chloroform (>88%), whilst for the smaller ones with interchromophoric distances <6 Å, additional nonradiative pathways lead to a pronounced fluorescence quenching.
Fiscal Policy, Multidimensional Poverty, and Equity in Uganda: A Child-Lens Analysis
Authors: Cuesta Jose , Jellema Jon , Ferrone Lucia
Published: May 2020

Fiscal incidence analysis is the most widely used methodology to assess the distributional effects of fiscal policies. However, despite 40 years of use and refinement, it still lacks. A focus on the redistributive capacity of fiscal policy among children is increasingly important as policymakers pay growing attention to the disproportionate incidence of poverty among children globally. This paper brings a child-dedicated focus to fiscal incidence analysis by tracking child-relevant benefits, making child wellbeing the unit of analysis, and using multidimensional child poverty metrics. The analysis—Commitment to Equity for Children, or CEQ4C—integrates three analytical frameworks: public finance, fiscal incidence, and multidimensional child poverty. The paper develops a proof of concept for Uganda that includes measurement, diagnostics, and a policy simulation package replicable across diverse contexts. The proof of concept confirms that CEQ4C provides a higher-resolution fiscal incidence analysis for children than the traditional fiscal incidence analysis.
The influence of occupation on the longevity of Japanese traditional artists
Authors: Hayashi Naoyuki , Kezuka Kazuhiro
Published: May 2020

The long-term lifestyle is known to affect lifespan and mortality. In particular, it is well known that exercise habit decreases the mortality. The effects of performing strenuous exercise, however, as an occupation over a lifetime have been unclear. Here we show the effects of various occupations that include being sedentary and performing music and exercise activities and/or birth year on longevity of 699 professional male artists either alive or dead, as reported in books and webpages. Kaplan–Meier analysis showed a significant effect of occupation type on longevity among the four Japanese traditional arts professions of Kabuki, Sado, Rakugo and Nagauta, which include strenuous exercise, and tea ceremonies, telling comic stories and playing instruments while sitting, respectively. Discrete-time logistic regression analysis showed that the lifespan was significantly shorter for Kabuki actors than among the other three Japanese traditional artists. This result suggests that daily strenuous exercise as an occupation shortens rather than prolongs the lifespan.

Published: May 2020

Quasi-phase-matched grating structures in lithium niobate waveguides with sub-micrometer periodicities will benefit the development of short-wavelength nonlinear optical devices. Here, we report on the reproducible formation of periodically poled domains in x-cut single-crystalline thin-film lithium niobate with periodicities as short as 600 nm. Shaped single-voltage poling pulses were applied to electrode structures that were fabricated by a combination of electron-beam and direct-writing laser lithography. Evidence of successful poling with good quality was obtained through second-harmonic microscopy and piezoresponse force microscopy imaging. For the sub-micrometer period structures, we observed patterns with a double periodicity formed by domain interactions and features with sizes <200 nm.
Anisotropic electronic transport properties of Ag-oped Mg3Sb2 crystal prepared by directional solidification
Authors: Li Xin , Xie Hui , Yang Bin
Published: May 2020

Ag-doped Mg3Sb2 crystals are successfully grown via a directional solidification method with high temperature gradient. The microstructure of the crystal is homogeneous and without precipitation. Both electrical conductivity and Seebeck coefficient are anisotropic in two crystallographic directions ([001] and [101]) due to anisotropic effective mass and mobility of the carriers. Thermal conductivity is isotropic too, and the maximum Seebeck coefficient is 265 μV K−1 in the [001] orientation, which represents a substantial improvement over previous results. As a consequence, the maximum power factor for the 2.5 at. % Ag-doped crystal is 1.21 mW m−1 K−2 in the [001] orientation, which results in an elevated ZT of 0.67 at T = 800 K. First principles calculations and Hall measurements are used to verify the experimental results.
Magnetic actuation and deformation of a soft shuttle

Published: May 2020

Here, we describe the magnetic actuation of soft shuttles for open-top microfluidic applications. The system is comprised of two immiscible liquids, including glycerol as the soft shuttle and a suspension of iron powder in sucrose solution as the magnetic drop. Permanent magnets assembled on 3D printed motorized actuators were used for the actuation of the magnetic drop, enabling the glycerol shuttle to be propelled along customized linear, circular, and sinusoidal paths. The dynamics of the hybrid shuttle–magnetic drop system was governed by the magnetic force, the friction at the interface of the shuttle and the substrate, and the surface tension at the interface of the shuttle and the magnetic drop. Increasing the magnetic force leads to the localized deformation of the shuttle and eventually the full extraction of the magnetic drop. The versatility of the system was demonstrated through the propelling of the shuttle across a rough surface patterned with microfabricated barriers as well as taking advantage of the optical properties of the shuttle for the magnification and translation of microscale characters patterned on a planar surface. The integration of the system with current electrowetting actuation mechanisms enables the highly controlled motion of the magnetic drop on the surface of a moving shuttle. The simplicity, versatility, and controllability of the system provide opportunities for various fluid manipulation, sample preparation, and analysis for a range of chemical, biochemical, and biological applications.
