Abstract
Background
Cerebral small vessel disease (CSVD) is a disorder of brain vasculature that causes various structural changes in the brain parenchyma, and is associated with various clinical symptoms such as cognitive impairment and gait disorders. Structural changes of brain arterioles cannot be visualized with routine imaging techniques in vivo. However, optical coherence tomography (OCT) is thought to be a “window to the brain”. Thus, retinal vessel parameters may correlate with CSVD characteristic brain lesions and cerebrospinal fluid biomarkers (CSF) of the neuropathological processes in CSVD like endothelial damage, microglial activation and neuroaxonal damage.

Methods
We applied OCT-based assessment of retinal vessels, magnetic resonance imaging (MRI), and CSF biomarker analysis in a monocentric prospective cohort of 24 patients with sporadic CSVD related stroke and cognitive impairment. MRI lesions were defined according to the STandards for ReportIng Vascular changes on nEuroimaging (STRIVE). Biomarkers were assessed using commercially available ELISA kits. Owing to the unavailability of an age-matched control-group lacking MRI-characteristics of CSVD, we compared the retinal vessel parameters in CSVD patients (73.8 ± 8.5 years) with a younger group of healthy controls (51.0 ± 16.0 years) by using an age- and sex-adjusted multiple linear regression analysis model.

Results
Among the parameters measured with OCT, the Wall to Lumen Ratio (WLR) but not Mean Wall Thickness (MWT) of the superior branch of the retinal artery correlated significantly with the volume of white matter hyperintensities on MRI (rs = − 0.5) and with CSF-levels of Chitinase 3 like 1 protein (rs = − 0.6), zona occludens 1 protein (rs = − 0.5) and GFAP (rs = − 0.4). MWT and WLR were higher in CSVD than in controls (28.9 μm vs. 23.9 μm, p = 0.001 and 0.32 vs. 0.25, p = 0.001).

Conclusions
In this exploratory study, WLR correlated with the volume of white matter hyperintensities, and markers of vascular integrity, microglial activation, and neuroaxonal damage in CSVD. Further prospective studies should clarify whether retinal vessel parameters and CSF biomarkers may serve to monitor the natural course and treatment effects in clinical studies on CSVD.

Abstract
Background
Liver transplantation is a final treatment for decompensated liver disease.

Aim
Description of post-liver transplant histopathology. We enrolled 89 patients divided into two groups according to if they underwent on demand liver biopsy (n = 34; 38.2%) or not (n = 55; 61.8%). Albumin-bilirubin (ALBI) score and model for end-stage liver disease (MELD) assessed the degree of liver dysfunction.

Results
Patient underwent liver biopsy (LB) was 44.65 ± 8.46 years old, mainly males (88.2%) with average MELD of 8.74 ± 4.71. Most patients were positive pre-transplant for HCV (91.2%) and 29.4% had hepatocellular carcinoma on top of hepatitis C. Patients underwent LB had worse liver dysfunction by ALBI score (− 2.62 ± 0.6 vs. − 2.96 ± 0.5; p = 0.014) but comparable MELD. The time till first biopsy was 19.88 ± 11.22 (4-44) months. It was not different statistically with various histopathology (p > 0.05). Histopathology of first biopsy was viral chronic hepatitis (50%), acute rejection (20.6%), steatohepatitis (11.8%), chronic rejection (5.9%), chronic hepatitis (5.9%), biliary obstruction (2.9%), and cytomegalovirus hepatitis (2.9%). Most patients were F1 (38.2%) and A1 (35.3%). The immunosuppressive drug regimen had no impact on the histopathology (p > 0.05). Patients with hepatitis C pre-transplant had in a descending manner the following histological diagnosis (p = 0.001): viral chronic hepatitis 16 (51.6%), acute rejection 7 (22.6%), steatohepatitis 4 (12.9%), chronic rejection 2 (6.5%), biliary obstruction 1 (3.2%), and CMV hepatitis 1(3.2%). Some patients required on demand second (n = 9) and third biopsied (n = 5) that were the same as the first biopsy or completely different.

Conclusion
Liver biopsy is a useful tool for diagnosis of liver transplantation complications.
Experience Effect in the Impact of Free Trial Promotions
Authors: Reza Sadat , Ho Hillbun , Ling Rich , Shi Hongyan 
Published: May 2020

Although the use of free samples is extensive across industries, the effects of free samples across individuals with varying levels of usage have yet to be systematically examined. The models discussed in the literature consider targeting only the current nonusers of a product. In this research, we examine the question of targeting the current users both analytically and empirically for an experience good. Our analytical discussions highlight the reasons why some current users may be effective targets for free-sample promotions. We then conduct an empirical analysis using a data set on pre- and post-free-sample promotion mobile data usage provided by a telecom firm. The empirical findings are consistent with our analytical results. Specifically, we find the initial usage level to be a key determinant of both the redemption rate of a free-sample offer and the subsequent change in usage owing to free-sample redemption. In our context, the redemption rate increased from the low-percentile users to the high-percentile users. We also find that the change in usage was (weakly) monotonically increasing up to the [Formula: see text] percentile of usage distribution. Beyond the [Formula: see text] percentile, the effect was generally not significant. We discuss the managerial and policy implications of our findings.

Published: May 2020

Compartment syndrome of the limb is a true orthopaedic emergency that warrants prompt evaluation and treatment. Acute compartment syndrome of the limb is not uncommon and has the potential to cause devastating morbidity and mortality. Failure to provide urgent surgical intervention once established can lead to irreversible tissue damage within hours of onset. Compartment syndrome can occur across all limbs, the buttocks and even the abdomen, but this article focuses solely on the diagnosis of acute compartment syndrome of the limb. Acute compartment syndrome can have a wide range of causes, with trauma representing approximately 70% of cases.

Published: May 2020

We are developing a robust and economic electro-optical remote sensing methodology to monitor the state of health and hydration of trees, endemic to subtropical regions. We measured reflectance spectra with Fourier transform infrared (FTIR) of three samples of two different oak trees. We find that spectral bands suitable for monitoring the state of the health and senescence of the oak include intervals around 0.9 µm and 1.8 µm. The easiest and the most cost-effective strategy would be to implement an electro-optical remote sensing radiometric system featuring a commercial camera incorporating a traditional charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) detectors and a wideband transmission filter, from about 0.8 to 1 µm.

) and a perovskite (methyl ammonium lead iodide) absorber layer is simulated in this work, and a comparison of performance parameters is made with other transport layers from the literature. The issue of optimization regarding the thickness of the absorber layer and the doping concentration in the absorber and transport layers has been addressed, and the effect of defect concentration at the interface has been investigated. Optimum performance is achieved with an absorber layer of thickness 800 nm. Linear grading is also introduced in the absorber layer by varying the concentration of different halides, which increases the efficiency by approximately 8% owing to the increase in the short circuit current density.

Non-contact reflection-mode optical absorption spectroscopy using photoacoustic remote sensing
Authors: Bell Kevan , Haji Reza Parsin 
Published: May 2020

A method of remote optical absorption spectroscopy is described that
utilizes the photoacoustic remote sensing detection technique. A
nanosecond tunable excitation source is used to excite thermo-elastic
pressure-induced elasto-optic modulations within targets across a wide
wavelength range from 210 to 680 nm, providing optical absorption
contrast. These modulations are read remotely as back-reflected
intensity variations within a continuous-wave 1310 nm detection beam.
The absorption spectra of several samples including dyes and
biological macromolecules are captured with an 8 mm working distance
in reflection-mode without the use of containment chambers or acoustic
detection. This represents an initial investigation into the
characteristics of this technique, which may facilitate optical
absorption measurement within previously inaccessible sample types due
to their size or opacity.

Published: May 2020

Social movements, that have been conceptualized as new with serious transformations in their content and implementation since the 1960s, which have the potential to influence current political/social debates or decisions, has entered social life in a way that no one can easily ignore in terms of their effects. The increasing visibility and impact of social movements, especially since the 2000s, differ significantly depending on whether countries have established democracy or not. The social movements that are widespread throughout the country do not cause a radical change in the country's administration in countries with a built-in democracy culture and consciousness, like Turkey and France, through the examples of countries studied in this work. Because in these countries, there is a system in which demands could be reflected through democratic elections. On the other hand, in countries where democracy culture is not fully established, like Egypt and Tunisia, social movements are thought to have a high capacity to cause radical changes in the administration with the influence of different actors. ​Extended English summary is in the end of Full Text PDF (TURKISH) file. Özet Güncel politik/toplumsal tartışmalara ya da kararlara yön vererek onları etkileme potansiyeline sahip olan ve 1960’lı yıllardan itibaren içeriğindeki ve uygulanış şeklindeki ciddi dönüşümler ile yeni olarak kavramsallaştırılan toplumsal hareketler etkileri itibariyle artık kimsenin kolayca göz ardı edemeyeceği bir şekilde toplumsal hayata girmiştir. Özellikle 2000’li yıllardan itibaren toplumsal hareketlerin artan görünürlüğü ve etkisi ise sonuçları itibariyle ülkelerin yerleşik bir demokrasiye sahip olup olmamasına göre önemli derecede farklılık arz etmektedir. Ülke genelinde yaygınlaşan toplumsal hareketler, bu çalışmada incelenen ülke örnekleri üzerinden yerleşik bir demokrasi kültürüne ve bilincine sahip olan ülkelerde –Türkiye ve Fransa gibi- ülke yönetiminde köklü bir değişikliğe sebep olmamaktadır. Çünkü bu ülkelerde demokratik seçimler yoluyla taleplerin yansıyacağı bir sistem bulunmaktadır. Öte yandan, demokrasi kültürü tam olarak yerleşmemiş ülkelerde –Mısır ve Tunus gibi- toplumsal hareketlerin farklı aktörlerin de etkisiyle yönetimde köklü değişikliklere yol açma kapasitesinin yüksek olduğu düşünülmektedir.

Latar Belakang: Kekurangan gizi menjadi salah satu penyebab kesakitan dan kematian pada anak-anak usia dibawah lima tahun. Ibu yang bekerja sebagai buruh pabrik mempunyai waktu bekerja lebih lama, sehingga berhubungan dengan waktu yang dimiliki ibu untuk menyediakan makanan yang bergizi bagi keluarganya. Upaya yang diharapkan berdampak pada perbaikan status gizi adalah meningkatkan mutu konsumsi makanan melalui program Kadarzi. Rendahnya pengetahuan dan perilaku ibu terhadap gizi merupakan faktor yang berpengaruh pada pencapaian program Kadarzi. Oleh karena itu, upaya pencegahan terjadinya gizi kurang dapat melalui peningkatan pengetahuan gizi dan kesadaran ibu akan pentingnya perilaku Kadarzi. Tujuan: Penelitian ini bertujuan untuk mengetahui hubungan pengetahuan dan perilaku ibu buruh pabrik tentang Kadarzi dengan status gizi anak balita. Metode: Desain studi adalah cross sectional pada 39 anak balita usia 12-36 bulan dari ibu buruh pabrik di kelurahan Pagersari, Ungaran. Status gizi berdasarkan BB/TB dinilai dengan z-score. Pengetahuan dan perilaku Kadarzi diukur menggunakan kuesioner, pengukuran kadar yodium garam di laboratorium , asupan makanan dan konsumsi keanekaragaman makanan menggunakan recall 3x24 jam. Analisis menggunakan Rank Sparman, dan korelasi parsial Hasil: Sebanyak 15,4% balita termasuk kategori kurus.
