Authors: Eskiler Gamze Guney , Cecener Gulsah , Dikmen Gokhan , Egeli Unal , Tunca Berrin
Published: May 2019

Objective:

In the present work, we report for the first time the therapeutic potential of talazoparib
(BMN 673)-SLNs for the treatment of BRCA1 deficient Triple Negative Breast Cancer (TNBC).
BMN 673-SLNs were produced by hot-homogenization technique and then characterized.

Methods:

The cytotoxic and apoptotic effects of BMN 673-SLNs compared with BMN 673 were determined
on HCC1937BRCA1-/-, HCC1937-R resistant TNBC and MCF-10A control cell lines. BMN 673-
SLNs were found to have reduced particle size (219.5 ± 1.45 nm) and thus more stable (-28.4 ± 2.52
mV) than BMN 673 (1652 ± 2.46 nm and -18.6 ± 0.45 mV) at 4°C.

Results:

In vitro cell line studies demonstrated that BMN 673-SLNs showed significant cytotoxic effects
on HCC1937 (29.8%) and HCC1937-R cells (35.7%) at 10 nM for 12 days compared with BMN 673
(HCC1937 cells: 34.0% and HCC1937-R cells: 93.8% at 10 nM for 12 days) (p<0.05). Additionally,
BMN 673-SLNs (40.1%) reduced the toxicity of BMN 673 (53.1%) on MCF-10A control cells thanks to
unique physical properties.

Conclusion:

The apoptotic rates in the 10 nM BMN 673-SLNs treatment (88.78% and 85.56%) for 12
days were significantly higher than those in 10 nM BMN 673 (82.6% and 25.86%) for 12 days in HCC1937
and HCC1937-R cells, respectively (p<0.01). Furthermore, these effects were consistent with the findings
of colony formation, wound healing and calcein accumulation analysis. In conclusion, the therapeutic potential
of BMN 673-SLNs provides a promising chemotherapeutic strategy for the treatment of drugresistant
TNBC.

The influence of the geometric shape of the samples on the uncertainty of the coefficient of thermal conductivity measurement of materials by the method of a laser flash has been studied. Using a method of mathematical modeling in the Comsol Multiphysics software, a model that simulates the process of measuring the coefficient of thermal conductivity of samples made of graphite, Mg2Si0.4Sn0.6 and bismuth telluride using a laser flash method has been created. Samples of cylindrical shape with plane-parallel sides and samples in the form of a truncated cylinder, as well as samples in the form of a parallelepiped with a square base, were investigated. It is shown that the measurement uncertainty of samples with plane-parallel sides and sizes up to 12.7 mm, does not exceed 2%. For samples in the form of a truncated cylinder with a diameter of 3 mm and at an angle of ϕ= 1.5°, the measurement uncertainty does not exceed 3%. With an increase in the sample diameter and the ϕ angle, the measurement uncertainty increases significantly.

Properties of Co-Si thin films produced by thermal treatment of Co and Si layers are studied in this article. Co/Si layers were produced by chemical vapor deposition. The two-layer structure was annealed at elevated temperatures for the formation of cobalt silicide. Thermoelectric properties of the film structures were investigated in the temperature range 300-800 K. Temperature dependences of thermopower and resistivity as well as structural data indicate the formation a multilayer structure with Si-rich and Co-rich layers.

This paper reports on epitaxial film growth and characterization of α-Ga2O3, a novel wide bandgap semiconducting material. The films were deposited by halide vapour phase epitaxy on basal plane sapphire substrates. The films were from 0.5 μm to over 10 μm in thickness, the latter being the record value by now. Structural and optical properties of the specimens were studied. All specimens were structurally uniform, single phase, and had a corundum-like r3c structure similar to that of sapphire substrate. It was found that the full width at half maximum for the (0006) α-Ga2O3 reflection varies with layer thickness and approaches 240 arcsec for the thickest layer. Both thin and thick layers were transparent in the visible and UV spectral range up to the absorption edge at 5.2 eV.

Irradiations of the nanostructured silicon with Si+ and He+ ions were carried out with energies of 200 and 150 keV, respectively. Raman scattering showed destruction of the structure after irradiations and accumulation of defects at different fluences of irradiation. It is shown that monocrystalline silicon films are amorphized under irradiation at 0.7 displacement per atom. However, porous silicon does not completely amorphize at 0.5 displacement per atom, a weak signal is observed in the Raman spectra corresponding to the amorphous silicon phase, and at the same time there is an obvious signal from the crystalline phase of silicon. The size of nanocrystallites in the structure of porous silicon was estimated at different fluences of irradiation.

The analysis of plastic deformation of metals and polymethylmethacrylate under dynamic loading is carried out using a relaxation model of plastic deformation. The invariance of the parameters of the relaxation model of plasticity to the strain history allows us to obtain any set of deformation curves from a united viewpoint, both monotonic, with varying yield strength, and non-monotonic, with emerging and varying yield drop, as it is observed in experiments. The increase of the yield strength of high-strength 2.3Ni-1.3Cr steel together with the hardening effect both under high-rate and slow deformation is also modeled on the basis of the relaxation model. Using DP600 steel and nanocrystalline nickel as an example it is shown that the relaxation model of plasticity allows one to predict a smooth transition to the plastic deformation stage at slow quasi-static effects of ~ 10–3 s – 1, and also the appearance of a yield drop effect at strain rates of 500–6000 s –1. It is also shown that the developed approach allows one to simulate similar effects under high-rate deformation of polymethylmethacrylate. Thus, it was demonstrated using specific materials as an example that it is possible to effectively predict the deformation dependencies of the materials studied in a wide range of strain rates of 10-4-104 s-1 based on the parameters of the relaxation model of irreversible deformations.

AbstractThe features of the manifestation of the flexo-magnetoelectric effect in magnetically uniaxial films under the local influence of an electric field on their surface are investigated. It is shown that with its increasing influence, there is a gradual transformation of the structure of the 180° domain boundary from the Bloch to the quasi-Bloch, and at a certain field value to the Néel boundary. It was revealed that in large fields it is possible to nucleate a 0° domain boundary with a non-Bloch structure, the laws of which have analogies with the formation of magnetic inhomogeneities on defects of the “potential well” type. The contribution of the partial parts of the inhomogeneous magnetoelectric interaction due to the presence of div m and curl  m in the phenomena under consideration is also determined.

AbstractThe specific heat, thermal expansion, permittivity, and electrocaloric effect in bulk of BaTiO_3 (BT) samples in the form of nano- (nBT-500 nm) and micro- (mBT-1200 nm) ceramics fabricated using spark plasma sintering and solid-state plasma techniques have been investigated. The size effect has been reflected, to a great extent, in the suppression of the specific heat and thermal expansion anomalies and in the changes in the temperatures and entropies of phase transitions and permittivity, and a decrease in the maximum intensive electrocaloric effect: $$\Delta T_{{{\text{AD}}}}^{{\max }}$$ = 29 mK ( E = 2.0 kV/cm) for nBT and $$\Delta T_{{{\text{AD}}}}^{{\max }}$$ = 70 mK ( E = 2.5 kV/cm) for mBT. The conductivity growth at temperatures above 360 K leads to the significant irreversible heating of the samples due to the Joule heat release in the applied electric field, which dominates over the electrocaloric effect.

AbstractThe electronic and optical properties of gold fullerenes are studied in the framework of the Hubbard model. The expressions of the Fourier transforms of anticommutator Green functions have been obtained for gold fullerenes Au_16 and Au_20, the poles of which determine the energy spectrum of the system under consideration. The calculations are performed for the thermodynamic means that characterize jumps of electrons from a nanosystem site to a neighboring site, the correlation functions demonstrating the possibility of existing two d electrons with oppositely oriented spin projections on the same site of the fullerenes consisting of gold atoms. The optical absorption spectra are presented. The optical absorption peaks of ions $${\text{Au}}_{{20}}^{ - }$$ and $${\text{Au}}_{{16}}^{ - }$$ correspond to a near-infrared spectral region, where the light absorption by blood or a soft tissue is vanishingly small; thus, these ions can be used as a new class of contrast improvements and phototherapeutic means for diagnostics and treatment of cancer.

AbstractWe report on the results of experiments devoted to analysis of conditions and characteristics of “bounce” (approach and interaction through a gaseous buffer envelope) of water droplets moving in a gaseous media with different parameters: velocity and direction of motion, temperature, and composition. Experiments were performed in flows of air, water vapor, and combustion products. Peculiarities of bounce of droplets with different initial temperatures are considered, and the results obtained at 18–20 and 60–80°C are compared. More than 1000 collisions of droplets recorded by high-speed photography are divided into groups of bounce, coalescence, separation, and disruption. The results of criterion processing using the Weber numbers are obtained.

AbstractIn this paper, we measured thresholds H _cr of explosive decomposition of thin ( h = 1 mm) samples of PETN-Al composites with densities in the range of ρ = 0.9–1.7 g/cm^3 and variations in the concentration of aluminum inclusions in the range of 0.025–1.0 wt % upon exposure to pulses of a neodymium laser (λ = 1064 nm, 14 ns). For each ρ, inclusion concentrations n _opt, at which the threshold for explosive decomposition of H _cr is minimal, are obtained. The velocities of air shock waves (ASWs) were determined depending on sample density ρ, and the times of the start of explosive decomposition were determined depending on the inclusion concentration. The amplitude (in relative units) and time shift of the maximal pressure of an ASW at the piezodetector are determined depending on sample density. It is concluded that the explosion is governed by the SW mechanism at high densities. As sample ρ decreases, the completeness of the explosion increases, with the most likely mechanism for small ρ being explosive burning. The efficiency of explosive decomposition is higher for samples with lower densities.

AbstractThe peculiarities of resistive switching in capacitors with yttria-stabilized hafnia layers were studied. The characteristics of current transport in the initial state and after electroforming and resistive switching at different temperatures were examined. The parameters of a small-signal equivalent circuit of a capacitor were determined for switching into low- and high-resistance states. These parameters suggest that the resistance of filaments changes after each successive switching. This provides an opportunity to use such measurements to determine the nature of resistive switching and verify the reproducibility of its parameters. The contribution of electron traps to switching was revealed. Ion migration polarization was observed at temperatures above 500 K, and the activation energy of ion migration and the ion concentration were determined. The effect of resistive switching under the influence of temperature was observed and interpreted for the first time.

AbstractUsing a statistical approach, we have estimated the size of water clusters and the number of free molecules participating in transport phenomena. The sizes of clusters and the number of molecules in them, as well as the number of free water molecules and their mean free paths, have been determined using experimental data on the temperature dependence of viscosity and density of water. It has been concluded that a temperature of 36.6°C is a special point in the range of 0–100°C. At temperatures higher than this value, the binding energy of a molecule with a cluster decreases abruptly, while the concentration of free molecules sharply increases. Quantitative data have been compared with the parameters of the superplastic state of titanium. As an example, we consider metabolism in functioning of erythrocytes of blood in an adult human.

As part of the study of polymer systems based on a chlorine photosensitizer, photodithazine (PD), photodynamic therapy was used to study the fluorescence and Rayleigh scattering spectra upon excitation at wavelengths lambdaex = 260, 280, 400, and 450 nm. Non-toxic water-soluble poly-N-vinylpyrrolidone (PVP) and vegetable polysaccharide were used as the polymer. sodium alginate (SA). The data of the PD-SA dual system is characterized by variability of characteristics depending on the preparation conditions, while in the PD-SA-PVP ternary complex, there is a favorable mutual influence of two SA and PVP polymers on the PD molecule, due to the creation of a local microenvironment of the active center PD with increased polarity . It was shown that the introduction of tryptophan (Trp), used as a substrate in model photo-oxidation processes, when testing the effectiveness of photosensitizers in the generation of singlet oxygen, does not significantly change the fluorescence parameters of the PD-SA-PVP complex.

The THz-TDS in the frequency range of 0.05–1.0 THz has been used to study the blood serum of rats in dynamics of experimental liver cancer. THz transmission spectra of samples from healthy rats and for 14 and 28 days after implantation of tumor cells have a similar shape, but differ in amplitude. The protein content decreases for the case of 28th day of the implantation, as it have been measured by biochemical analysis. The observed changes in the THz response are explained by a decrease in the number of protein molecules and water bounded with it. Those results correlate with decrease in the refractive index in the visible and near IR range from 480 to 1550 nm, measured with a multiwave refractometer.

The GaN(0001) layers were synthesized by hydride vapor-phase epitaxy, and GaN(10 $$\bar {1}$$ 1) layers, by metal-organic vapor-phase epitaxy, with the growth completed by hydride vapor-phase epitaxy. It was shown that layers of the polar GaN(0002) have a longitudinal elastic stress of –0.45 GPa and the minimum full width at half-maximum of the X-ray diffraction rocking curve ω_θ ~ 45 arcmin, whereas for the semipolar GaN(10 $$\bar {1}$$ 1), these values are –0.29 GPa and ω_θ ~ 22 arcmin, respectively. A conclusion is drawn that the combined technology of semipolar gallium nitride on a silicon (100) substrate is promising.

Abstract — The effect of low-dose γ radiation on the mechanisms of low-frequency conductivity of mesoporous silicon has been studied. It has been shown that γ irradiation preserves the hopping character of conductivity at a change of the frequency of phonon lattice vibrations, a decrease in the size of the hop, and a shift of the level of the capture of traps to the Fermi level in the band gap, which makes the structure with mesoporous silicon irradiated by γ radiation promising for the creation of multifunctional resistive and capacitive devices.

It is experimentally established that the luminescence spectrum of diamond at room temperature contains one or two peaks in the form of Gauss curves. This result is related to the exciton-phonon interaction in diamond, which, along with the zero-phonon line, contains first and second order phonon repetitions. This phenomenon is typical only for natural diamonds and is absent in synthetic samples. Therefore, it can be used to identify cut diamonds (diamonds).

End User–Informed Mobile Health Intervention Development for Adolescent Cannabis Use Disorder: Qualitative Study
Authors: Bagot Kara , Hodgdon Elizabeth , Sidhu Natasha , Patrick Kevin , Kelly Mikaela , Lu Yang , Bath Eraka
Published: May 2019

Background

The rates of cannabis use continue to increase among adolescents and the current interventions have modest effects and high rates of relapse following treatment. There is increasing evidence for the efficacy of mobile technology–based interventions for adults with substance use disorders, but there is limited study of this technology in adolescents who use cannabis.

Objective

The goal of our study was to elucidate elements of an app-based adjunctive intervention for cannabis cessation that resonate with adolescents who use cannabis.

Methods

Adolescents, aged between 14 and 17 years, who used cannabis were recruited from San Diego County high schools. Semistructured focus groups (6 total; N=37) were conducted to examine the ways in which participants used smartphones, including the use of any health behavior change apps, as well as to elicit opinions about elements that would promote engagement with an app-based intervention for adolescent cannabis cessation. An iterative coding structure was used with first cycle structural coding, followed by pattern coding.

Results

Themes that emerged from the analysis included (1) youth valued rewards to incentivize the progressive reduction of cannabis use, which included both nontangible rewards that mimic those obtained on social media platforms and prosocial activity-related rewards, (2) having the ability to self-monitor progression, (3) peer social support, (4) privacy and confidentiality discrete logo and name and usernames within the app, and (5) individualizing frequency and content of notifications and reminders.

Conclusions

Integrating content, language, interfaces, delivery systems, and rewards with which adolescents who use cannabis are familiar, engage with on a day-to-day basis, and identify as relevant, may increase treatment engagement and retention for adolescents in substance use treatment. We may increase treatment effectiveness by adapting and individualizing current evidence-based interventions, so that they target the needs of adolescents and are more easily incorporated into their everyday routines.

Published: May 2019

The exponential growth of online information and communication technologies such as texting and social media sites like Facebook, Instagram, and Snapchat have opened up new possibilities for child and youth care (CYC) practitioners to engage with children, youth, and families. Yet very little is known about the therapeutic use of these technologies as a direct CYC practice method. Hence, this qualitative, course-based research project aimed to explore the use of social media as a therapeutic practice by CYC students at MacEwan University. The Instagram social networking site was used to collect data. A thematic analysis identified four overarching themes: (a) a relationship, engagement, and communication building tool, (b) a source of support and information, (c) a creative space for self-expression, and (d) a safe place. The results of this course-based study indicate that CYC students use social media responsibly in their work with children, youth, and families. The use of social media appears to have a positive impact and beneficial use in CYC as long as it is utilized and maintained in a professional manner. More research into social media is, however, required to help CYC practitioners keep pace with information and communication technologies and become well-informed about their use and misuse.

Divisibility of qubit channels and dynamical maps
Authors: Davalos David , Ziman Mario , Pineda Carlos
Published: May 2019

The concept of divisibility of dynamical maps is used to introduce an analogous concept for quantum channels by analyzing the simulability of channels by means of dynamical maps. In particular, this is addressed for Lindblad divisible, completely positive divisible and positive divisible dynamical maps. The corresponding L-divisible, CP-divisible and P-divisible subsets of channels are characterized (exploiting the results by Wolf et al. \cite{cirac}) and visualized for the case of qubit channels. We discuss the general inclusions among divisibility sets and show several equivalences for qubit channels. To this end we study the conditions of L-divisibility for finite dimensional channels, especially the cases with negative eigenvalues, extending and completing the results of Ref.~\cite{Wolf2008}. Furthermore we show that transitions between every two of the defined divisibility sets are allowed. We explore particular examples of dynamical maps to compare these concepts. Finally, we show that every divisible but not infinitesimal divisible qubit channel (in positive maps) is entanglement breaking, and open the question if something similar occurs for higher dimensions.

The distribution of benefits that was felt by the community who manages the ecotourism is inseparable from the access and power mechanism that they own. Through the bundle of power such as technology, capital, market, workforce, knowledge, authority, social identity and social relation, are used by the ecotoursim management community to obtain and maintain access towards resources. Through this bundle of power they are also capable of strengthening the performance of the marine ecotourism institution’s managment in Kampung Arborek. Therefore, equality in access and power for the community is needed to open new oppurtunities to obtain benefits from managing the ecotourism and also reinforcement of the performance of the institution’s management.
