Innovative strategies for reducing the burden of chronic liver disease
Authors: Greenslade Lynda
Published: September 2020

Alcohol consumption is increasing in the UK, bringing an increased incidence of cirrhosis, which in turn can lead to hepatic encephalopathy. This complication of cirrhosis can be devastating for patients and their families, and incurs a large health economic burden to the NHS. Cirrhosis is, of course, preventable. As disease prevention is at the heart of the NHS Long Term Plan, it can be used as the basis of a 10-year plan to avoid the complications of chronic liver disease

Authors: Breau Genevieve , Thorne Sally , Baumbusch Jennifer , Hislop T. Greg , Kazanjian Arminee
Published: September 2020

Individuals with intellectual disability (ID) obtain breast, cervical, and colorectal cancer screening at lower rates, relative to the general population. This cross-sectional survey study explored how primary care providers and trainees recommend cancer screening to patients with ID, using a standardized attitudes questionnaire and vignettes of fictional patients. In total, 106 primary care providers and trainees participated. Analyses revealed that participants' attitudes towards community inclusion predicted whether participants anticipated recommending breast and colorectal cancer screening to fictional patients. Further research is needed to explore these factors in decisions to recommend screening, and how these factors contribute to cancer screening disparities.

Published: September 2020

Applied quantum optics stands to revolutionise many aspects of information technology, provided performance can be maintained when scaled up. Silicon quantum photonics satisfies the scaling requirements of miniaturisation and manufacturability, but at 1.55 µm it suffers from problematic linear and nonlinear loss. Here we show that, by translating silicon quantum photonics to the mid-infrared, a new quantum optics platform is created which can simultaneously maximise manufacturability and miniaturisation, while reducing loss. We demonstrate the necessary platform components: photon-pair generation, single-photon detection, and high-visibility quantum interference, all at wavelengths beyond 2 µm. Across various regimes, we observe a maximum net coincidence rate of 448 ± 12 Hz, a coincidence-to-accidental ratio of 25.7 ± 1.1, and, a net two-photon quantum interference visibility of 0.993 ± 0.017. Mid-infrared silicon quantum photonics will bring new quantum applications within reach.
Design of Si-rich nitride interposer waveguides for efficient light coupling from InP-based QD-emitters to Si3N4 waveguides on a silicon substrate
Authors: Chatzitheocharis D. , Ketzaki D. , Calò C. , Caillaud C. , Vyrsokinos K.
Published: September 2020

In this paper, we present a systematic analysis for the design of Si-rich-nitride (SRN) based interposer waveguide layers interfacing InP-based devices and Si3N4 waveguides, towards monolithic co-integration of active and passive elements through a Back-End-Of-Line process. The investigation is performed via extensive 2D-eigenvalue and 3D-FDTD electromagnetic simulations and focuses on three different interposer designs, where performance in terms of coupling loss and back reflections is exchanged for fabrication complexity. In addition, a tolerance analysis is performed for the demonstration of the proposed coupling scheme’s resilience to fabrication misalignments. The calculations use for the refractive index of the SRN interposer, real values extracted from ellipsometry measurements of a novel ultra-Si-rich-nitride material developed and engineered for this purpose. This new material provides tunability in the real part of the refractive index with low-stress crack free samples grown up to 500nm thickness. Test structures with cutbacks featuring waveguides of 500 × 500nm2 cross section formed via e-beam lithography reveal 15dB/cm propagation losses in line with similar amorphous silicon-rich nitride (aSi:N) materials. The proposed coupling concept although assumes an InP active medium, can be applied also with GaAs based lasers and dual facet devices such as Semiconductor Optical Amplifiers (SOAs) and electroabsorption modulators. In addition, all proposed designs are compatible in terms of critical dimensions with low cost 248nm DUV lithography targeting to maximize the low-cost advantage of the Si3N4 platform with very high coupling performance. Our results are expected to pave the way for the generation of a versatile, low cost, high performance monolithic InP-Quantum-Dot (QD)/Si3N4 platform on a common Si substrate.
Dynamic pulse propagation modelling for predictive femtosecond-laser-microbonding of transparent materials
Authors: Sahoo Pankaj K. , Feng Tao , Qiao Jie
Published: September 2020

A dynamic pulse propagation modeling for femtosecond laser bonding of Borofloat glass is presented. The temperature evolution and internal modifications are predicted by incorporating the nonlinear electron dynamics along with temperature dependent thermal properties. The modelling predicts the spatial and temporal distribution of absorption coefficient and plasma density that gives quantitative estimations of the heat affected zone and weld geometry. The impact of focusing condition on heat affected zone and weld geometry is investigated, which for the first time to our knowledge allows to numerically determine the desired relative position between the geometrical focus of a femtosecond-laser-pulse and the interface of the two substrates to be welded. The prediction of the modelling on the offset distance is applied to weld Borofloat glass plates having optical contact and can be applied to other dielectric solids.
Visual tracking for mobile optical wireless communications
Authors: Chen Biao , Yu Haotian
Published: September 2020

Acquisition, tracking, and pointing (ATP) mechanisms are generally adopted for optical wireless communications (OWCs) to maintain a strict alignment state for reliable communication. ATP mechanisms conventionally employ beacon lights to determine the orientation of the remote optical terminal. They typically cannot maintain a steady alignment under mobile conditions. A novel visual tracking approach is proposed to address this issue by establishing a shape beacon at the OWC terminals. The shape beacon can be sensed from virtually all directions with a camera; hence, visual tracking is an acceptable ATP solution for mobile OWCs. Results of numeric analysis indicate that visual tracking is suitable for mobile OWCs as well as conventional OWCs with acceptable accuracy. Experiments were performed to demonstrate the visual tracking procedures using the vehicle itself as the shape beacon.

Authors: Yu Miao , Cheng Zhaochen , Hong Chang , Shi Yuhang , Peng Zhigang , Wang Min , Wang Pu
Published: September 2020

We investigate an all-fiber all-polarization-maintaining dispersion-managed ultrafast fiber laser mode-locked by nonlinear polarization evolution in polarization-maintaining fibers both numerically and experimentally. We find that the laser can operate in different regions among a wide net dispersion, including dispersion-managed solitons, dispersion-managed dissipative solitons, bound state solitons and noise-like pulses. The laser generates the dispersion-managed soliton pulses with a maximum 3 dB bandwidth of 37.84 nm, which can be further compressed to 161.37 fs. Moreover, pulses generation simulation under different net dispersion condition has been carried out. Nonlinear pulse evolution dynamics in laser cavity has been analyzed through numerical simulation as well. The results are basically consistent with the experimental ones.

Published: September 2020

Digital holography is a promising display technology that can account for all human visual cues, with many potential applications i.a. in AR and VR. However, one of the main challenges in computer generated holography (CGH) needed for driving these displays are the high computational requirements. In this work, we propose a new CGH technique for the efficient analytical computation of lines and arc primitives. We express the solutions analytically by means of incomplete cylindrical functions, and devise an efficiently computable approximation suitable for massively parallel computing architectures. We implement the algorithm on a GPU (with CUDA), provide an error analysis and report real-time frame rates for CGH of complex 3D scenes of line-drawn objects, and validate the algorithm in an optical setup.

Authors: Nugroho Widi , Aditya Siska , Swastomo Rahadi , Aulanni'am Aulanni'am
Published: September 2020

Background and Aim: Cattle are an important economic asset for the rural community in East Java Province, Indonesia. The study aimed to provide updated data of cattle farm demography, productivity, as well as the role of the absence of a bull and nematodiosis in reduced productivity of beef cattle in an upland rural area of the province.

Materials and Methods: The study was conducted in Sukowono village, Bondowoso region. A Census survey was conducted to collect data through interviews with farmers. Further, 102 fecal samples were taken systematically and processed using a double centrifugation method to investigate the endoparasitic nematodiosis in the cattle population. The demographic data, productivity, and nematodiosis were analyzed descriptively. The difference between proportions was analyzed using Chi-square with 95% confidence limit. The associations were described in risk ratio with 95% confidence interval (CI).

Results: The total cattle population was 814 heads; the range of farm size was 1-7 (median: 2) cattle. Female cattle comprised 81.8% (666/814) of the cattle population but, only 5.5% (23/422) farmers kept both bull and mature female cattle. Pregnancy rate was 26.8% (145/542) of mature female cattle. The delayed first calving time appeared in 24.8% (62/250) of heifers and calving interval of >14 months occurred in 83.2% (149/179) of multiparous cows. The prevalence of endoparasitic nematodiosis was 43.1% (44/102, 95%, CI: 38.1-52.1%). Either the absence of the bull or the nematodiosis did not associate with pregnancy rate or calving interval of cows.

Conclusion: This study indicates that the productivity of the cattle in the study area was low but may not associate with the absence of a bull or nematodiosis.
Effect of Geographic Location, Ontogenesis on Essential Oil

Published: September 2020

The present study aimed at investigating the variation in the chemical composition of emitted volatile
organic compounds (VOCs) and essential oils obtained from fresh aerial parts of Inula viscosa
(Asteraceae) as affected by growth stage and geographical location zone. VOCs were extracted by
solid phase microextraction (SPME) method from whole aerial parts of I. viscosa during the vegetative
(spring-August) period, and from fresh leaves, closed pre-flowering buds and fully expanded flowers
during the full flowering season (October). The essential oils were extracted by hydrodistillation form
fresh organs during the flowering stage. GC/MS analysis of VOCs during the vegetative period revealed
sesquiterpene hydrocarbons as main components in the samples collected from the Mediterranean
zone (MID-1: 64.72-27.48%, MID-2: 32.09-76.77%). The profile of the samples from the
Irano-Turanian zone (IT) was quite different. Myrcenol was the main component in the leaves,
pre-flowering buds and fully expanded flowers from all locations (0.61-39.01%). E-nerolidol was the
main component in the hydrodistilled oil of all organs from the different locations (73.72-88.66 %).
Principle component and cluster analysis revealed that the chemical composition of the essential oils
and VOCs belonging to MID-zone were similar and quite different when compared to the composition
of the samples belonging to IT-zone. The results indicated the possible use of E-nerolidole as a stable
chemotype marker in I. viscosa taxonomy.
Density Functional Theory Calculation of Molecular
Descriptors for Simple Coumarins in Gas and Different Solvents
Authors: Sumalatha Poodari , Subbarao Mannam
Published: September 2020

The primary aim of this study is to show the importance of molecular structure analysis of
pharmaceutical active coumarins compounds using quantum chemistry methods based on density
functional theory. To explore the theoretical calculations for global descriptors, the standard Gaussian
09W program was used for coumarins compounds. The full geometry optimization was carried out by
the B3LYP/6-311G level of theory. The octanol-water and air-water partition coefficients were also
estimated using functional density theory. The order of the HOMO-LUMO energy gap for studied
coumarins in the gas phase is umbelliferone (UBA) < (herniarin) HNR ~ (crenulatin) CNT < (scopoletin)
SCT < (scoparone) SCO < (isoscopoletin) IST < (4-methylesculetin) MST < (umbelliferone-2-
carboxylic acid) UCA < (isofraxidin) IFD < (fraxetin) FXT < (aesculetine) ACT < (dapnetine) DPT.
Therefore, UBA molecule in gas phase is less stable. Compared to the measured index of electrophilicity
(DE). The MST molecule is stronger, more reactive, nucleophile electrophile at the gas phase and in
solvents. In all solvent phases, CNT and UCA molecules have lower values, which mean they are
strong nucleophiles. From the log P values of ACT and MST coumarins are in between 1.35-1.8, so
ACT and MST coumarins use oral and intestinal absorptions.

Sewage waters are the primary habitats to harbour antibiotic resistance bacteria (ARB) especially
multi-drug resistance (MDR) human enteric pathogens. Microorganisms acquire resistance towards
many commercial antibiotics due to their inappropriate use. In this study, human enteric pathogens
were isolated, identified and characterized and shows the resistance against five different clinically
significant commonly prescribed antibiotics. The bacterial strains were isolated from different sewage
treatment plants located in Delhi city, India. Samples were analyzed for the detection of pathogenic
human enteric bacteria through morphological, biochemical and molecular analysis. Methanolic leaf
extract of Murraya koenigii showed the significant antibacterial activity against multi drug resistant
human enteric pathogens. Thus, Murraya koenigii leaves would be a potential alterantive to antibiotic
regimens for the prevention of gastrointestinal infections.

Making the Diagnosis of Bile Acid Diarrhea
Authors: Walters Julian R.F.
Published: September 2020

Bile acid diarrhea is a frequent, treatable cause of functional diarrhea but is difficult to diagnose when the nuclear medicine 75seleno-taurohomocholic acid test is unavailable. An alternative approach is testing blood for the bile acid precursor, 7α-OH-4-cholesten-3-one, which is raised with increased bile acid synthesis. A recent article has defined measurements that have high negative and positive predictive values, further exploring how they can be improved by incorporating measures such as age, stool number, fibroblast growth factor 19, or plasma sulfated bile acids. Other articles have looked at the percentage of fecal primary bile acids. Together, they promise better use of diagnostic biomarkers for this condition.

Published: September 2020

Forested wetlands (FWs) are economically and environmentally important, so monitoring of change is done using remote sensing by several U.S. federal programs. To better understand classification and delineation uncertainties in FW maps, we assessed agreement between National Wetlands
Inventory maps based on aerial photography and field determinations at over 16 000 Forest Inventory and Analysis plots. Analyses included evaluation of temporal differences and spatial uncertainty in plot locations and wetland boundaries. User's accuracy for the wetlands map was 90% for FW
and 68% for nonforested wetlands. High levels of false negatives were observed, with less than 40% of field-identified wetland plots mapped as such. Epsilon band analysis indicated that if delineation of FW boundaries in the southeastern U.S. met the data quality standards (5 meters), then
the area within uncertainty bounds accounts for 15% to 30% of estimated FW area.

Nowe formy instytucjonalizacji pamięci na Bałkanach i w Polsce (komparatystyczne studium trzech przypadków)
Authors: Bogusławska Magdalena
Published: September 2020

The subject of the article is the characteristics of modern forms of memory institutionalization – the kind of commemorative practices and the related production and dissemination of knowledge in the public space. This topic seems especially important but also controversial in post-socialist countries, in which a major process of revision of the past is continues. This process becomes a part of the political pluralization of the public sphere and the expression of the emancipation of various previously marginalized groups. Using the example of the three museum:Museum of the Macedonian Struggle for Sovereignty and Independence, War Childhood Museum in Sarajevo and „Polin” Museum of the History of Polish Jews, the author discusses: – the articulation and afirmation of subjectivity by means of museum as an institution– the mechanism for shaping the authority of institutions so as to legimitize the interpretation of the past– the relationship between the particular, often fragmented registers of the memory and the dominant power discourses.
Król węgierski Andrzej II na tronie w Cesarstwie Łacińskim? Bałkański wątek Piątek Krucjaty
Authors: Pentek Zdzisław
Published: September 2020

The article focuses on the participation of the Hungarian King Andrew II in the Fifth Crusade in 1217. The author rejects the speculations (B. Hóman, S. Runciman, F. Van Tricht et al.) that the reason of the king’s decision was ascending the throne of the Latin Empire after the death of the emperor Henry in 1216. Due to the lack of evidence in sources for these speculations, the author claims that the reasons for which Andrew II took part in the Fifth Crusade were rather prestigious, devotional and ambition oriented.

Published: September 2020

A survey of 396 undergraduate and graduate students from 51 countries on 5 continents currently enrolled in Forestry or Related Natural Resource (FRNR) degree programmes was conducted of attendees to the International Union of Forest Research Organizations' (IUFRO) conference in Salt
Lake City, Utah, 2014. These perspectives come from some of the most active students in their respective fields. We explored the motivating reasons for enrolling in their current FRNR programme, and conversely why they may have been hesitant to do so. Results indicate that enjoyment of nature
was the most important factor on average driving the decision to enroll, closely followed by job satisfaction, concern for the environment, enjoyment of outdoor recreation, being outdoors, and an interest in subject material. Hesitancy factors included earning potential, availability of funding/scholarships,
and politically contentious issues. A number of significant differences were found across demographic categories. Of particular note was the greater hesitancy on the part of women and people of color to enroll in FRNR degree programmes compared to their white male counterparts. We discuss
the limitations of our study arising from its international scope and imbalance of responses among countries and regions.
Unreliable accounts: How regulators fabricate conceptual narratives to diffuse criticism – A response to Karthik Ramanna
Authors: Haslam Colin
Published: September 2020

Karthik Ramanna’s article titled “unreliable accounts: How regulators fabricate conceptual narratives to diffuse criticism” provides a critical insight into how Fair Value Accounting (FVA) was incorporated into the conceptual framework for general purpose financial reporting. Karthik reveals that the installation of FVA into the FASBs constitution can be understood through a framework: conceptual veiling. In this framework, the FASB is captured within the logics of financial market economics, assuming investors and capital market actors are best served by financial disclosures that reflect market valuations. Captured by these interests, the FASB needed to modify the narratives contained in the conceptual framework removing reliability and substituting faithful representation because much of what constitutes FVA disclosures are estimates and judgements of questionable reliability. A more forceful critical evaluation of the re-orientation of accounting practise from Historical Cost Accounting to FVA might have located changes in the context of the financialized company.
Existence and uniqueness of solutions for coupled systems of Liouville-Caputo type fractional integrodifferential equations with Erdélyi-Kober integral conditions
Authors: Subramanian Muthaiah , Zada Akbar
Published: September 2020

In this paper, we examine a coupled system of fractional integrodifferential equations of Liouville-Caputo form with nonlinearities depending on the unknown functions, as well as their lower-order fractional derivatives and integrals supplemented with coupled nonlocal and Erdélyi-Kober fractional integral boundary conditions. We explain that the topic discussed in this context is new and gives more analysis into the research of coupled boundary value problems. We have two results: the first is the existence result of the given problem by using the Leray-Schauder alternative, whereas the second referring to the uniqueness result is derived by Banach’s fixed-point theorem. Sufficient examples were also supplemented to substantiate the proof, and some variations of the problem were discussed.
Hate online: The creation of the “Other”
Authors: Wekesa Maloba
Published: September 2020

Social media has redefined the thinking around the capacity and intensity of interaction among individuals and groups of people across national and international borders. Messages on social media are instantaneous, unhinged to interpretation and inherently dialogic. Through app designs that encourage near addiction to use in various platforms, it is becoming more probable that public debates and social protests start, are fanned and may even be resolved online in these platforms. Many state actors including politicians, religious leaders and social commentators have exploited social media to drive their agenda; personal or otherwise. The anonymity and direct accessibility granted by social media to these actors have given them a brazen green light to promote hate online and a platform for divisive and anarchist agenda. In this paper, I explore the dynamics of hate in social media; how the “Other” is created and used as the target for hate online using the case of electioneering in Kenya. I will attempt to provide a structure profile of social media communication in Kenya during the electioneering period while correlating this to the functional features that facilitated hate on social media. I will deconstruct how the “Other” is created by examining discourse arguments and the underlying subjective benefits in the creation of the “Other”. I will then show how anonymity and publicity interact to promote the process of hate online. This paper employs a phenomenological approach, first propounded by Edmund Husserl, to illustrate how misinformation creates the “Other” and to profile how hate that is spread online is a by-product of this misinformation. The research validity in this paper is premised on the currency of social media as a new dynamic in communication requiring rigorous academic inquiry.
Schattenfiguren, Spektren, Gespenster als leuchtende Verheißung. Simon Kronbergs Sonderstellung in der deutschen Literatur des Expressionismus
Authors: Schönsee Dorothea Rebecca
Published: September 2020

Der Artikel untersucht den originären Beitrag Simon Kronbergs zur deutschen Literatur des Expressionismus. Der zu den „vergessenen und verkannten Autoren der expressionistischen Generation” (Lützeler) gehörende Kronberg ist bis heute kaum untersucht. Als Sohn jüdisch-galizischer Zuwanderer 1891 in Wien geboren, studiert er 1913 bei Emile Jacques-Dalcroze, dessen Licht- und Bewegungschoreographien ihn nachhaltig prägen. Weitere Stationen sind Düsseldorf bei dem Schauspieler-Paar Lindemann/Dumont, München und Berlin. 1934 emigriert er nach Palästina, wo er 1947 stirbt. Seine Texte entwerfen eine Sprache, deren sinnstiftende Bilder von seiner biographischen Erfahrung geprägt sind und jüdische Mystik, Tanz und Rhythmus auf spezifische Weise integrieren. Im Zentrum steht Kronbergs Konzeption des Schattens als einer Möglichkeit der Wandlung des Menschen in einer Welt der Rationalität und der Entkopplung des täglichen Lebens von Körper und Sinnlichkeit hin zu einer Erfahrung des Lichts. Am Beispiel seiner Erzählung “Chamlam” zeigt der Beitrag, dass seine Schattenfiguren in einem beachtenswerten Spannungsverhältnis zum Diskurs der Gespenster im Expressionismus stehen.
Broadband enhancement of second-harmonic generation at the domain walls of magnetic topological insulators
Authors: Rakhmanova Gulnaz , Iorsh Ivan V.
Published: September 2020

We show that the second-harmonic generation (SHG) is enhanced in the chiral one-dimensional electron currents in a broad frequency range. The origin of the enhancement is twofold: first, the linear dispersion of the quasiparticles and the associated plasmonic mode as well as the quasi-linear dispersion of plasmon-polariton result in the lift of the phase-matching condition. Moreover, the strong field localization leads to the further increase of the SHG in the structure. The results suggest that the chiral currents localized at the domain walls of magnetic topological insulators can be an efficient source of the second-harmonic signal in the terahertz frequency range.

Published: September 2020

The study aimed to determine the annual reproductive cycle of Siganus rivulatusfi females based on monthly variation of the gonadosomatic index (GSI) and histological changes in gonads. A total of 240 fish samples were collected monthly from small-scale (trammel nets) and recreational (angling and pot fishery) fishing from Gökova Bay, the southern Aegean Sea, between July 2017 and June 2018. The length and weight of female fish varied from 10.8 to 26.1 cm with a mean length of 18.7 ± 0.2 cm and from 14.98 to 293.42 g with a mean weight of 91.1 ± 2.93 g. GSI values began to increase in May, peaked in June and gradually decreased in July, indicating that the spawning season was early summer. A total of 240 gonads were histologically examined. Granular, pinkish structure of eggs was observed primarily between April and June, which was consistent with the increase in the gonadosomatic index. Post-spawning follicles were determined in July. Values of the gonadosomatic index gradually decreased after August and they were minimal between September and November. During this period, ovaries were surrounded by immature oocytes at the chromatin and peri-nucleolus stages. These results revealed thatSiganus rivulatusstarted vitellogenesis in April and the gonadosomatic index peaked in June.
Distribution of cyclopoid copepods in different subterranean habitats (southern Poland)

Published: September 2020

The majority of Polish studies on freshwater cyclopoids focused on surface water fauna. There are relatively few data on copepods of subterranean waters. Thus, in our research, copepods were collected from 37 different, mostly groundwater-dependent habitats (i.e. caves, springs, wells, interstitial and overhead environments) over a period of five years between 2005 and 2010. A total of 22 species belonging to eight genera were found. Some species, previously not recorded or known only from a few sites in Poland, proved to be a frequent component of subterranean communities.
#Personal vs #Party: A comparative study of candidates’ new media campaigning in Japan and the United Kingdom
Authors: Vincent Sean
Published: September 2020

This paper examines how new media is affecting candidate personal vote seeking behaviour, at the constituency level by comparing data from general elections in two countries with different styles of campaigning – party-centred campaigning in the United Kingdom (2015 & 2017) and candidate-centred campaigning Japan (2014 & 2017). By utilising both content analysis of candidates’ use of new media platforms and in-person interviews with candidates, this study gives a deep description of how individual candidates are using online campaigning and to what degree they are pursuing a personal, rather than party vote. This study confirms that that Japanese candidates use new media to run more candidate centred campaigns, replicating traditional campaign styles, but also finds that other factors, namely candidates’ levels of experience and the strength of the national party, play a role in how candidates utilise new media. Now more so than ever, candidates are relying on personal image promotion as a major element of their campaigns.
Ionic liquids: green solvents and reactive compounds? Reaction of tri-n-butylmethylphosphonium dimethylphosphate with elemental sulfur

Published: September 2020

The opening of the S8 ring with the formation of linear sulfur oligomers in the presence of tri-n-butylmethylphosphonium dimethylphosphate is shown. The reaction products are separated and characterized with 1H, 13C, 31P, 17O NMR spectroscopy, HD-MS, MALDI spectroscopy and XRD. It is shown that dimethylphosphate-anion is active in the reaction, and the addition of sulfur atoms occurs via the oxygen atom of dimethylphosphate-anion. It is found that a mixture of products is formed, which differ in the number of sulfur atoms in the chain. The assumptions were made about the mechanism of interaction of sulfur with tri-n-butylmethylphosphonium dimethylphosphate.

As the number of poorly soluble drugs is increasing, nanocrystals have become very interesting due to wide range of application possibilities. Curcuminwas used as a model active ingredient in this work. Even though it has many proven positive effects, due to its physicochemical issues, its possibilities have not been fully exploited. The goal of this work was to select optimal conditions for a top-down method for curcumin nanosuspension production, and to perform their comprehensive characterization applying complementary methodologies: dynamic light scattering, polarization and atomic force microscopy, thermal analysis, X-ray powder diffraction, antioxidant activity evaluation, release kinetics assessment, and screening of potential biological effects applying cell viability assays on normal human lung fibroblasts, human melanoma and human adenomacarcinoma cells. After 30 min of milling, nanosuspensions stabilized by polysorbate 80 and by its combinations with sucrose palmitate showed good stability, while curcumin crystal structure was unaltered. Obtained nanocrystals were well defined, with average diameter 120–170 nm and PDI of about 0.25, zeta potential was below −30 mV and pH~5 for all formulations. Nanodispersions exhibited high antioxidant potential and improved dissolution rate compared to the corresponding coarse dispersions. Although curcumin nanodispersions exhibited significant antiproliferative effect to each cancer cell line, the highest effect was towards adenocarcinoma cells.
