Abstract
The present study aims to investigate the mechanism of miR-15a-5p in the atherosclerotic (AS) inflammatory response and arterial injury improvement in diabetic rats by regulating fatty acid synthase (FASN). Initially, bioinformatics tools were applied to evaluate miRNAs and genes correlating with AS, and the target relation between miRNAs and FASN was measured using the Dual-Luciferase Reporter Assay. Subsequently the diabetic AS rat model was established and the surviving rats were divided into: negative control (NC), miR-15a-5p mimic, miR-15a-5p inhibitor, sh-FASN and miR-15a-5p + sh-FASN groups. Then a series of experiments were performed to examine the degree of AS in each group. The results revealed that compared with the NC group, the expressions of C-reactive protein (CRP), interleukin 6 (IL-6), intercellular cell adhesion molecule-1 (ICAM1) in rat arterial tissue, as well as the levels of low-density lipoprotein cholesterol (LDL-C), blood glucose (BG), triglycerides (TG), total cholesterol (TC) and Homocysteine (Hcy) in rat serum, were increased after inhibiting miR-15a-5p, while the level of high-density lipoprotein cholesterol (HDL-C) was decreased and the fat storage area was enlarged after this treatment (P&lt;0.05). In the miR-15a-5p mimic and sh-FASN groups, serum HDL-C levels were increased and the fat storage areas in arteries were reduced. The levels of CRP, IL-6, ICAM1 in rat arterial tissue, along with the levels of LDL-C, BG, TG, TC and Hcy in rat serum, were decreased (P&lt;0.05). Hematoxylin and Eosin (HE) staining and transmission electron microscopy (TEM) results showed AS lesions to be apparent in the arteries of rats in both the NC and miR-15a-5p inhibitor groups, but that in miR-15a-5p and sh-FASN group were improved, the miR-15a-5p mimic + sh-FASN group showed the most obvious improvement. Taken together, miR-15a-5p alleviates the inflammation response and arterial injury in diabetic AS rats by targeting FASN.

Published: June 2019

Objective
Prephonatory vocal fold angle trajectories may supply useful information about the laryngeal system but were examined in previous studies using sigmoidal curves fit to data collected at 30 frames per second (fps). Here, high-speed videoendoscopy (HSV) was used to investigate the impacts of video frame rate and sigmoidal fitting strategy on vocal fold adductory patterns for voicing onsets.

Method
Twenty-five participants with healthy voices performed /ifi/ sequences under flexible nasendoscopy at 1,000 fps. Glottic angles were extracted during adduction for voicing onset; resulting vocal fold trajectories (i.e., changes in glottic angle over time) were down-sampled to simulate different frame rate conditions (30–1,000 fps). Vocal fold adduction data were fit with asymmetric sigmoids using 5 fitting strategies with varying parameter restrictions. Adduction trajectories and maximum adduction velocities were compared between the fits and the actual HSV data. Adduction trajectory errors between HSV data and fits were evaluated using root-mean-square error and maximum angular velocity error.

Results
Simulated data were generally well fit by sigmoid models; however, when compared to the actual 1,000-fps data, sigmoid fits were found to overestimate maximum angle velocities. Errors decreased as frame rate increased, reaching a plateau by 120 fps.

Conclusion
In healthy adults, vocal fold kinematic behavior during adduction is generally sigmoidal, although such fits can produce substantial errors when data are acquired at frame rates lower than 120 fps.

We investigated the effect of the hydrostatic pressure on the optoelectronic properties of a quantum well (QW) based on δ-doped GaAs sandwiched by Ga1-xAlxAs. We study the case of a non-parabolic conduction band where the aluminum content is set at 30%. We perform our calculations in the context of the approximation of the envelope function formalism using the finite difference method. Results show that the transition energies decrease with the increase of the hydrostatic pressure, which causes remarkable modifications on the optical properties of the QW nanostructure. The non-parabolicity effect is more important for small QW (Lw ≤ 5nm) and less marked in narrow and large QW. In addition, we study the absorption coefficient for 8 nm/4 nm/8 nm geometry. On the one hand, the pressure increase creates a displacement of the optical absorption coefficient towards low energies and a decrease of the absorption peak value. On the other hand, the refractive index moves towards higher energies. We show that in the presence of a hydrostatic pressure and following its effect on intersubband transitions, these optical properties also depend on the dopant concentration rate and the quantum well width. Our study finds interests for the nano-fabrication of quantum wells and in particular for those used in optical and electronic applications.

Published: June 2019

Objective To evaluate the quality of life among university students with premenstrual syndrome (PMS).
Methods The cross-sectional study was conducted at the Faculdade Pernambucana de Saúde, in Recife, Brazil, between August 2016 and July 2017. Sociodemographic, gynecological, and lifestyle variables, and PMS occurrence, were investigated among 642 students. The short form of the World Health Organization Quality of Life (WHOQOL Bref) questionnaire was used to evaluate four domains of the quality of life of the students: physical, mental, social relationships, and environmental. The American College of Obstetricians and Gynecologists' criteria were used to define PMS.
Results Of the 642 students, 49.9% had PMS, 23.3% had mild PMS and 26.6% had premenstrual dysphoric disorder (PMDD). Most of the students were between 18 and 24 years old, had regular menstrual cycles, and practiced physical activity. Regarding the physical and mental domains of the WHOQOL-Bref questionnaire, a statistically significant difference was observed between the students who did not have and those who had mild or PMDD (p < 0.001). A difference was also found between the students who did not have PMS and those who had mild PMS in the social relationships (p = 0.001) and environmental domains (p = 0.009).
Conclusion Mild PMS and PMDD are prevalent among university students on health-related courses, and the syndrome can affect the students' self-assessment of all the domains of quality of life.

Published: June 2019

Objective To investigate the relationship between maternal exposure to alcohol and low birthweight (LBW).
Methods The literature search was performed in January 2017 using the following electronic databases: Medline, Embase, LILACS, SciELO, Web of Science, Scopus, CINHAL, Proquest, and PsychInfo. The search strategy used the following terms: alcohol drinking, binge drinking, alcohol-related disorders, alcoholism, alcohol addiction/use/abuse/consumption, light/moderate/social/low drinking, low birthweight, case-control studies, retrospective studies, and cohort studies. No restrictions regarding language or publication date were considered. The literature search yielded 2,383 articles, and after screening and eligibility assessment, 39 articles were included in the systematic review, and 38 studies were included in the meta-analysis.
Results Maternal alcohol consumption was associated with LBW among retrospective cohort studies (relative risk [RR] = 1.37; 95%CI [confidence interval]:1.10–1.77; I2 = 98.4%; p < 0.01). Prospective cohort studies (RR = 1.11; 95%CI: 0.98–1.25; I2 = 81.5%; p < 0.01), and case-control studies (odds ration [OR] = 1.16; 95%CI: 0.68–1.97; I2 = 61.2%; p = 0.05) showed no association between alcohol and LBW. No publication bias was identified, and the meta-regression showed that the sample size influenced the high heterogeneity among retrospective cohort studies. The subgroup analysis showed differences in association between groups when compared by sample size, type of adjustment, or crude measures and publication year.
Conclusions We have not found an association between alcohol consumption during gestation and LBW in the analysis in all of the subgroups. In addition, we have found a high heterogeneity between the primary studies, which is related to methodological differences in the conduction of these studies.
Reconstruction of Distal Radius Osteochondral Defects Using Metatarsal Autografts: a Multi-case Series
Authors: Goon Patrick K.Y. , Stougie Shirley D. , Vaghela Kalpesh R. , Coert J. Henk 
Published: June 2019

Objective Delayed reconstruction of the articular surface of the distal radius after trauma is a difficult problem for hand surgeons, and the common solution is usually partial or total wrist fusion, relieving pain but sacrificing motion. A relative novel reconstructive technique addresses the problem with a free microvascular osteochondral flap, using the 3rd metatarsal (3MT) bone. We investigate the possibility of using the same donor as a graft rather than a free flap.
Methods This was a prospective clinical study of patients with isolated lunate facet damage following trauma who underwent surgery to remove the damaged articular surface and in whom the defect was reconstructed with an osteochondral graft from the base of the 3MT. All of the patients were followed-up at specific time intervals, with pre- and postoutcome measures taken, including pain, grip strength, range of motion (ROM), and postoperative radiographs and computed tomography (CT) scans to evaluate graft resorption and union. Only patients with isolated distal radius defects were included.
Results The average follow-up period was of 51 months (range: 14–73 months). The results of 7 patients included an average improvement of the pain score in the visual analogue scale (VAS) by 3 points, with an average arc of motion of 135°. In all, there was radiographic evidence of full incorporation of the graft, with no resorption. Donor site morbidity was minimal.
Conclusions The current gold standard for distal radius articular surface reconstruction remains a free 3MT osteochondral flap. However, our results using the base of the 3MT as a graft shows promise, and if further follow-up confirms comparable results to the free flap technique, this would mean an easier and equally robust reconstruction without complicated microsurgery.

The effects of lower limb wearable resistance on sprint running performance: A systematic review
Authors: Feser Erin H. , Macadam Paul , Cronin John B. 
Published: June 2019

ABSTRACTThe aim of this review was to examine the literature that has used lower limb wearable resistance (WR) during sprint running. A systematic search was completed to identify acute and longitudinal studies assessing the effects of lower limb WR on sprint running performance from international peer‐reviewed journals. The Boolean phrases (limb OR leg OR lower extremity) AND (sprint*) AND (resist* OR weight OR load*) were used to search PubMed, SPORTDiscus, and Web of Science electronic databases. Ten studies met the inclusion criteria and were retained for analysis that reported the acute kinematic and kinetic effects (n = 8), acute performance effects (n = 3), and longitudinal effects (n = 1). Results showed that the WR micro‐loading (0.6–5% body mass) significantly increased contact time (2.9–8.9%), decreased step frequency (−1.4 to −3.7%), and slowed total sprint times (0.6–7.4%). Unloaded sprinting immediately following sprints with lower limb WR resulted in no significant change to total sprinting times. One longitudinal training study did not find a significant effect on maximal sprinting speed for non‐trained participants. It can be concluded that not all step kinematic variables are affected during sprinting with an added load up to 5% body mass. Therefore, coaches can use lower limb WR to selectively overload certain aspects of sprint running, in particular stride frequency. It also appears that lower limb WR overloads sprint movement velocity and may provide a stimulus to increase horizontal force output, therefore, it may be inferred that lower limb WR has the potential to elicit improved sprinting performance.

Published: June 2019

Abstract
We review the progress of multi-wavelength distributed feedback (DFB) quantum cascade lasers (QCLs) as sources for broadband mid-infrared (mid-IR) spectroscopy. While it is possible to tune the emission wavelength of DFB QCLs in a frequency range of about 5 cm−1 by varying the operating temperature and driving current, continuous, deterministic and mode-hop free tuning remains challenging. To use these laser sources for broadband spectroscopy applications and to exploit their narrow linewidth, the equalization of the power across the multicolor spectrum is another requirement. Various approaches are reviewed: conventional DFB QCL arrays, surface emitting DFB QCL arrays, on-chip beam combined DFB arrays, multi-channel Vernier-based switching DFBs, and dual-wavelength DFBs. The results are presented to highlight the applicability of these sources for broadband and high-resolution trace gas spectroscopy. The results for multi-species trace-gas spectroscopy using dual-wavelength QCLs are presented in more detail, where the best precision as determined from Allan-Werle plots was obtained for measurement of NH3 with 0.02 parts per billion (ppb) at 100 s integration time, and typical values for the other trace gases of the order of 0.1 ppb. These results indicate that spectrometers using dual-wavelength QCLs can serve as an all-in-one solution for high precision gas spectroscopy.

Published: June 2019

Abstract
We use a combination of experiments, numerical analysis and theory to investigate the nonlinear dynamic response of a chain of precompressed elastic beams. Our results show that this simple system offers a rich platform to study the propagation of large amplitude waves. Compression waves are strongly dispersive, whereas rarefaction pulses propagate in the form of solitons. Further, we find that the model describing our structure closely resembles those introduced to characterize the dynamics of several molecular chains and macromolecular crystals, suggesting that our macroscopic system can provide insights into the effect of nonlinear vibrations on molecular mechanisms.
Current distribution in narrow translation-invariant quantum-Hall-systems with lateral density modulation
Authors: Gerhardts Rolf R 
Published: June 2019

Abstract
A previously developed self-consistent screening and magneto-transport theory for laterally confined, translation-invariant quantum-Hall-systems is applied to two-dimensional electron systems created by a donor sheet with a lateral density modulation. The previous calculations, assuming a homogeneous donor charge density, could explain experimental results on the spatial distribution of an applied source-drain-current, and the resulting Hall potential, only for the ‘edge-dominated’ low-magnetic-field part of a quantum-Hall-plateau, where the current flows through incompressible stripes near the edges. For the high-magnetic-field regime of the plateau, they predicted current flow only in a narrow stripe in the center of the sample, whereas the experiments found current in a wide region of its bulk. Assuming a suitably modulated donor charge density, we can avoid this discrepancy, and we obtain a strong dependence of the distribution of the applied current on magnetic field, lattice temperature, and the current-strength.
Lunar surface potential and electric field*
Authors: Li Lei , Zhang Yi-Teng , Zhou Bin , Feng Yong-Yong 
Published: June 2019

Abstract
The Moon has no significant atmosphere, thus its surface is exposed to solar ultraviolet radiation and the solar wind. Photoemission and collection of the solar wind electrons and ions may result in lunar surface charging. On the dayside, the surface potential is mainly determined by photoelectrons, modulated by the solar wind; while the nightside surface potential is a function of the plasma distribution in the lunar wake. Taking the plasma observations in the lunar environment as inputs, the global potential distribution is calculated according to the plasma sheath theory, assuming Maxwellian distributions for the surface emitted photoelectrons and the solar wind electrons. Results show that the lunar surface potential and sheath scale length change versus the solar zenith angle, which implies that the electric field has a horizontal component in addition to the vertical one. By differentiating the potential vertically and horizontally, we obtain the global electric field. It is found that the vertical electric field component is strongest at the subsolar point, which has a magnitude of 1 V m−1. The horizontal component is much weaker, and mainly appears near the terminator and on the nightside, with a magnitude of several mV m−1. The horizontal electric field component on the nightside is rotationally symmetric around the wake axis and is strongly determined by the plasma parameters in the lunar wake.

Abstract
The Square Kilometre Array (SKA) will be the world’s largest synthesis radio telescope, which is designed to answer major scientific questions such as those relating to the cosmic origin and fundamental forces in the universe. With the SKA entering into the phase of pre-construction, more than 100 institutes in about 20 countries including China have been involved in the associated key technology development. The Dish Verification Antenna China (DVA-C) is a concept prototype which has been built to meet the requirements of the SKA’s scientific goals. It utilizes a unique skin-and-rib structure with single-piece panel reflectors. This paper presents details on the design and measured performances of DVA-C, as well as the preliminary observational results. Current applications of the DVA-C are also introduced.

Abstract
The characteristic of flow and heat transfer of Al2O3-water nanofluids flowing through a horizontal ventilated cavity is investigated numerically. The bottom wall is subjected to a sinusoidal hot temperature profile, whereas the other boundaries are assumed to be thermally insulated. In fact, the flow comes forcedly into the system from the bottom of the left vertical wall and leaves it from the top of the right one by suction. The simulations focus on the effects of different key parameters, such as Reynolds number (200 ≤ Re ≤ 5000), nanoparticle’s concentration (0 ≤ ϕ ≤ 0.05) and phase deviation of the sinusoidal heating (γ equal 0 or π), on the flow and thermal patterns and heat transfer performances. The obtained results show that the presence of nanoparticles increases the heat transfer and the mean temperature within the cavity. In addition, the phase shift of the heating temperature may lead to periodic solutions for weaker values of Re and contributes to an increase or a decrease of heat transfer depending on the value of ϕ and the convection regime.

Published: June 2019

Abstract
We present a computational study on the electronic and optical properties of a representative C-made and Boron-Nitride-made (BN) planar molecule of interest for potential applications in the solid state domain. In particular, we analyzed the case of Coronene (C24H12) in its BN and perfluorinated analogues. We performed all electrons Density Functional Theory (DFT) and Time Dependent-DFT (TD-DFT) calculations using a localized Gaussian basis-set in combination with a hybrid exchange-correlation functional. For all the systems we have calculated different electronic properties and the optical absorption spectra. A discussion on the possible implications of the general trends, observed for the BN-made clusters properties as compared to their C-based parents, will be given.
