Authors: Rahmah Meidina , Amin Ramzi , Ansyori AK
Published: September 2019

Introduction: Central retinal vein occlusion (CRVO) is the second most common retinal vascular disease after diabetic retinopathy and is estimated to affect more than 16 million adults worldwide. Treating the underlying cause of occlusion of the central retinal vein, reducing the risk factors, and early and proper management are the keys toward a better prognosis in patients with CRVO. Repeated frequent treatment of CRVO with macular edema with intravitreal anti-vascular endothelial growth factor (anti-VEGF) is an effective treatment to improve visual outcome. In this case report we assess the 3-month efficacy of anti-VEGF therapy in CRVO.

Method: In this case, a 52-year-old man presented with an acute loss of vision over the last week in his left eye. His baseline visual acuity was 1/60 and his central retinal thickness (CRT) on Optical Coherence Tomography (OCT) was 523 μm. Fundus examination revealed a hemorrhage in all four quadrants, hard exudates, swelling of the optic nerve, and macular edema. Laboratory test confirms hyperlipidemia and we consult this patient to Internal Medicine Department. This patient got 3 monthly injections of 1,25 mg Bevacizumab.

Results: By 3 months, the OCT appeared fairly normal and the visual acuity improved to 6/60

Conclusion: Anti-VEGF therapy is effective for treating macular edema secondary to CRVO

Published: September 2019

Introduction : to determine the effect of citicoline 1000 mg oral supplementation given for 4 weeks on electroretinography abnormalities in patients with NPDR (non-proliferative diabetic retinopathy).

Methods : prospective, double blind, randomized clinical trial. Thirty-eight patients who matched the inclusion and exclusion criteria were randomized into two groups: the placebo (P-NPDR) and citicoline (C-NPDR).  In the end, there were 18 eyes in citicoline group and 16 eyes in placebo group. The primary outcome was P50 and N95 amplitude in PERG within group and intergroup which were taken at the baseline and 4 weeks after treatment.

Results : at the end of treatment, the N95 amplitude in C-NPDR showed improvement, 4.85 (1.9-10.3) µV, before treatment to 5.7 (1.9-17.1) µV, after treatment with P = 0.04. Median P50 amplitude improved in both groups, with C-NPDR: 3.1 µV to 3.8 µV (p = 0.89), and P-NPDR: 3.5 µV, to 4.5 µV (p = 0.10). Delta ∆N95 amplitude is higher in C-NPDR, while delta ∆P50 amplitude is higher in P-NPDR, with P values 0.35 and 0.45.

Conclusion : Oral citicoline may induce a significant improvement in mean N95 amplitude before and after the treatment. P-NPDR showed positive trend in P50 amplitude while in C-NPDR showed positive trend in N95 amplitude, but these values were not statistically significant (P = 0.45; P= 0.35).

Authors: KOZJUK Viktor
Published: September 2019

Introduction. Postcrisis tendency to enhance central bank’s macrofinancial responsibility should be related to real-financial inter-linkages rethinking but not to activistic demand management. Different approaches on how price stability and financial stability are inter-related, as well, as different institutional modalities of how to achieve them are making more complicate optimal institutional design of central bank with increased zone of responsibility.

Purpose. Taking into account different macroeconomic viewpoints on the role of financial instability in macroeconomic fluctuations and institutional challenges for central bank independence the purpose of the paper is to validate that enhanced macrofinancial responsibility of central banks should be balanced by additional measures in direction to facilitate autonomous regulatory status.

Results. Different views on how to enhance macroeconomic stability and what the role of central banks in new macrofinancial environment provide serious challenge for optimal designing of central bank’s macrofinancial responsibility. The problem not only relate to how price and financial stability are inter-related but also to how define the wrong way policy then price and financial stability are in non-linear relations. The difficulties in this segment may affect far reaching political consequences while assessing central bank from political economy point of view. Also it is necessary to take into account that macroprudential toolkit may overlap with monetary policy instruments providing additional regulatory distortions. Clear institutialisation of relations between price and financial stability responsibilities will help to avoid political economy type of manipulations with central bank new tasks. Priority of price stability should be kept while financial stability mandate should be clarified and tied to macroprudential regulation. In the same time more active central bank’s participance in the post-crisis economy should be based not on standard Keynesian activism but on enhanced financial responsibility balanced with protection of central bank independence in new regulatory areas.

Conclusions. It the article it is stressed that enhanced macrofinancial responsibility should be based on unchanged priority of price stability mandate, increased level of central bank independence and coordination between monetary and macroprudential policies. It is shown that vulnerability of macrofinancial responsibilities to political pressure is going to increase. Political independence of central banks should protect them in the area of price stability and financial stability all together.

Introduction. One of the manifestations of financial globalization is the formation and development of cross-border links of transnational banks. This expands opportunities for investment and contributes to the economic development of many countries. At the same time, the increasing complexity of financial ties strengthens the cross-border interdependence of transnational banks, leading to the transfer of financial shocks that arise in some countries to others.

The purpose. The article aims to explore the role of multinational banks in the transmission of global systemic risk, identify existing problems supervision of multinational banks as globally systemically important financial institutions and identify solutions.

Results. The article deals with the processes of transmission by transnational banks of global systemic risk in the framework of the “theory of infection of financial markets”. The influence of the “general creditor effect” on the spread of crisis phenomena between the economies of different countries is analyzed. The direction of influence of cross-border links of transnational banks on financial stability of the banking system of the country is clarified. Approaches to the identification of globally systemically important banks have been highlighted in accordance with international practice, and tasks have been identified to strengthen regulation and supervision of the activities of transnational banks.

Conclusion. Today, regulators have limited ability to prevent the transmission of global systemic risk multinational banks. Many institutional mechanisms exist at national level and aimed at maintaining the financial stability of banking systems and crisis management of banks, there are no globally. However, only coordinated decisions on measures of overcoming the crisis can ensure effective implementation of anti-crisis programs globally

Multilayer structures comprising of SiO2/SiGe/SiO2 and containing SiGe nanoparticles were obtained by depositing SiO2 layers using reactive direct current magnetron sputtering (dcMS), whereas, Si and Ge were co-sputtered using dcMS and high-power impulse magnetron sputtering (HiPIMS). The as-grown structures subsequently underwent rapid thermal annealing (550–900 °C for 1 min) in N2 ambient atmosphere. The structures were investigated using X-ray diffraction, high-resolution transmission electron microscopy together with spectral photocurrent measurements, to explore structural changes and corresponding properties. It is observed that the employment of HiPIMS facilitates the formation of SiGe nanoparticles (2.1 ± 0.8 nm) in the as-grown structure, and that presence of such nanoparticles acts as a seed for heterogeneous nucleation, which upon annealing results in the periodically arranged columnar self-assembly of SiGe core–shell nanocrystals. An increase in photocurrent intensity by more than an order of magnitude was achieved by annealing. Furthermore, a detailed discussion is provided on strain development within the structures, the consequential interface characteristics and its effect on the photocurrent spectra.

⋆ suggests that θ is small for these most compact of systems. We confirm this hypothesis using a hierarchical Bayesian analysis, showing that 68% of CB disks around short-period SB2s have θ < 3.°0. Near coplanarity of CB disks implies near coplanarity of CB planets discovered by Kepler, which in turn implies that the occurrence rate of close-in CB planets is similar to that around single stars. By contrast, at longer periods ranging from 30 to 105 days (where the nodal degeneracy can be broken via, e.g., binary astrometry), CB disks exhibit a wide range of mutual inclinations, from coplanar to polar. Many of these long-period binaries are eccentric, as their component stars are too far separated to be tidally circularized. We discuss how theories of binary formation and disk–binary gravitational interactions can accommodate all these observations.

We present new Hubble Space Telescope imaging of a stream-like system associated with the dwarf galaxy DDO 68, located in the Lynx-Cancer void at a distance of D ∼ 12.65 Mpc from us. The stream, previously identified in deep Large Binocular Telescope images as a diffuse low surface brightness structure, is resolved into individual stars in the F606W (broad V) and F814W (∼I) images acquired with the Wide Field Camera 3. The resulting V, I color–magnitude diagram (CMD) of the resolved stars is dominated by old (age ≳ 1–2 Gyr) red giant branch (RGB) stars. From the observed RGB tip, we conclude that the stream is at the same distance as DDO 68, confirming the physical association with it. A synthetic CMD analysis indicates that the large majority of the star formation activity in the stream occurred at epochs earlier than ∼1 Gyr ago, and that the star formation at epochs more recent than ∼500 Myr ago is compatible with zero. The total stellar mass of the stream is ∼106
M
⊙, about 1/100 of that of DDO 68. This is a striking example of hierarchical merging in action at the dwarf galaxy scales.

Because of the plasma pressure gradient across the lunar wake boundary, the interplanetary magnetic field is enhanced in the lunar wake. In previous works, the solar wind ions that enter into the near lunar wake are found to have an unimportant influence on the magnetic field within the lunar wake. In this study, two cases of a 22%–70% reduction of the magnetic field in the near lunar wake are first observed by the Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon’s Interaction with the Sun mission (ARTEMIS). The magnetic field depressions are caused by the refilling of dense plasma clouds (with densities of 0.20–0.47 cm−3) into the near lunar wake. The ions of the plasma clouds that originate from the reflected solar wind ions in the lunar dayside are accelerated into the near lunar wake by the solar wind convection electric field. The source regions of the reflected ions can be traced back to the lunar magnetic anomalies over the sunlit surface. Pressure (magnetic pressure + thermal pressure) balances are roughly maintained for both cases at the boundary between the plasma cloud and the ambient plasma. Our results imply that the interaction between the solar wind and lunar magnetic anomalies drastically disturbs the near-Moon electromagnetic environment.

L1521F is found to be forming multiple cores and it is cited as an example of the densest core with an embedded VeLLO in a highly dynamical environment. We present the core-scale magnetic fields (B-fields) in the near vicinity of the VeLLO L1521F-IRS using submillimeter polarization measurements at 850 μm using JCMT POL-2. This is the first attempt to use high-sensitivity observations to map the sub-parsec-scale B-fields in a core with a VeLLO. The B-fields are ordered and very well connected to the parsec-scale field geometry seen in our earlier optical polarization observations and the large-scale structure seen in Planck dust polarization. The core-scale B-field strength estimated using the Davis–Chandrasekhar–Fermi relation is 330 ± 100 μG, which is more than 10 times the value we obtained in the envelope (the envelope in this paper is the “core envelope”). This indicates that B-fields are getting stronger on smaller scales. The magnetic energies are found to be 1 to 2 orders of magnitude higher than nonthermal kinetic energies in the envelope and core. This suggests that magnetic fields are more important than turbulence in the energy budget of L1521F. The mass-to-flux ratio of 2.3 ± 0.7 suggests that the core is magnetically supercritical. The degree of polarization is steadily decreasing toward the denser part of the core with a power-law slope of −0.86.
Atmospheric Circulation of Brown Dwarfs and Jupiter- and Saturn-like Planets: Zonal Jets, Long-term Variability, and QBO-type Oscillations
Authors: Showman Adam P. , Tan Xianyu , Zhang Xi
Published: September 2019

Brown dwarfs and directly imaged giant planets exhibit significant evidence for active atmospheric circulation, which induces a large-scale patchiness in the cloud structure that evolves significantly over time, as evidenced by infrared light curves and Doppler maps. These observations raise critical questions about the fundamental nature of the circulation, its time variability, and its overall relationship to the circulation on Jupiter and Saturn. Jupiter and Saturn themselves exhibit numerous robust zonal (east–west) jet streams at the cloud level; moreover, both planets exhibit long-term stratospheric oscillations involving perturbations of zonal wind and temperature that propagate downward over time on timescales of ∼4 yr (Jupiter) and ∼15 yr (Saturn). These oscillations, dubbed the quasi-quadrennial oscillation (QQO) for Jupiter and the semiannual oscillation (SAO) on Saturn, are thought to be analogous to the quasi-biennial oscillation (QBO) on Earth, which is driven by upward propagation of equatorial waves from the troposphere. To investigate these issues, we here present global, three-dimensional, high-resolution numerical simulations of the flow in the stratified atmosphere—overlying the convective interior—of brown dwarfs and Jupiter-like planets. The effect of interior convection is parameterized by inducing small-scale, randomly varying perturbations in the radiative–convective boundary at the base of the model. Radiative damping is represented using an idealized Newtonian cooling scheme. In the simulations, the convective perturbations generate atmospheric waves and turbulence that interact with the rotation to produce numerous zonal jets. Moreover, the equatorial stratosphere exhibits stacked eastward and westward jets that migrate downward over time, exactly as occurs in the terrestrial QBO, Jovian QQO, and Saturnian SAO. This is the first demonstration of a QBO-like phenomenon in 3D numerical simulations of a giant planet.
Measuring the Distances to Quasars at High Redshifts with Strong Lensing

Strongly lensed quasars with time-delay measurements are well known to provide the “time-delay distances”

S
. The corresponding redshifts of the quasars may be up to z

S

The high-redshift distances would sample the Hubble diagram between SNe Ia and the cosmic microwave background, model-independently providing direct information on the evolution of the nature of our universe, for example, the dark energy equation of state parameter w(z). We apply our method to the existing lensing system SDSS 1206+4332 and get

at z

BACKGROUND: Asthma is considered a chronic health illness that not only resulted in physical symptoms but also emotional effects. It is; therefore, so important to assess the quality of life of asthmatic patients besides their level of disease control.
AIM: To determine the correlation of asthma control with the health-related quality of life (HRQOL) of asthmatic children in Egypt.
METHODS: One hundred and twenty-eight asthmatic Egyptian children were enrolled in the study. They were subjected to asthma severity grading, asthma control questionnaire (ACQ) and pediatric asthma quality of life questionnaire (PAQLQ). Studied cases were taken from 6 primary and preparatory schools, Giza governorate.
RESULTS: The mean child control score was significantly higher in not well-controlled asthmatics compared to well-controlled asthmatics (p < 0.005). The not well controlled asthmatic children showed significantly lower activity limitation score, symptoms score, and overall asthmatic score compared to controlled asthmatic children (p < 0.05). The severity of asthma shows significant positive correlation with symptoms score, emotional function score and overall asthmatic score (p < 0.05).
CONCLUSION: The quality of life for the asthmatic children is strongly correlated with the level of asthma control and severity.
Nomen omen. Toponyms predict recolonization and extinction patterns for large carnivores
Authors: Tattoni Clara
Published: September 2019

The names given to places are a legacy of the past distribution of animal and plant species. The hypothesis tested in this work is that the density of toponyms can be used to predict the range of two large and charismatic species over time: the wolf and the brown bear in Italy. Kernel density maps of the toponyms were created and different thresholds of density were overlapped with the present and the historical ranges for both species. The density level maps were tested with the Kappa statistics against available historical ranges for both species. The pattern of the density in toponyms overlapped with the pattern of contraction and expansion reported in literature for both species over time. The minimum historical distributions of wolves and brown bears occurred at the highest densities of toponyms (95% isopleth value) and, overall, the various kernels thresholds showed an excellent agreement with the historical maps with an average Kappa of 0.84 ± 0.5.
