Authors: Kutlu Nermin , Oturak Halil 
Published: December 2018

Abstract
Titanium dioxide(TiO2) is a well-known material which is non-toxic with efficient photoactivity, high stability, low-cost and corrosion-resistant. Up to today’s technology, TiO2 films are coated for various applications in the scientific area. In this study, bilayer TiO2 films were coated on indium tin oxide(ITO) layers that have different characteristic properties. The devices designed as homemade of Direct Current Magnetron Sputtering (DCMS) and Spray Pyrolysis Deposition (SPD) coating methods were used to coat the first and second layers of bilayer TiO2 films, respectively. The optical and crystalline characterizations of bilayer TiO2 films were analyzed by UV-VIS spectroscopy and XRD techniques. The XPS spectrum showed that O2 molecules simply oxidize from Ti3+ to Ti4+ after SPD coating method. The characterization results of TiO2 films showed change in optical band gap value and crystalline structure of TiO2 bilayer.

Published: December 2018

AbstractIn the present study, the Fe-doped TiO2 modified nanoparticles was successfully synthesized by the combination of the sol-gel method and heat treatment, and the degradation of methyl orange was tested by the combination method of ultrasonic radiation and mechanical agitation. The effects of different factors on the degradation of methyl orange (MO) solution were studied, such as ultrasonic irradiation time, the ultrasonic frequency, the added amount of catalyst, the initial pH value, the initial concentration of methyl orange, and revolutions per minute. The optimal experimental conditions for sonocatalytic degradation of the MO obtained were: ultrasonic irradiation time = 60 min, pH value = 3.0 and revolutions per minute = 500 rpm. By means of response surface analysis, the best fitting conditions were as follows: ultrasonic frequency = 36.02 kHz, added amount of catalyst = 490.50 mg/L, the initial concentration of methyl orange = 9.22 mg/L, and the optimum condition was close to the experimental data by response surface method. Under optimal conditions, the sonocatalytic degradation of MO was 99%. The degradation of MO showed that the combination of Fe-doped modified TiO2 nanoparticles, mechanical agitation and ultrasonic irradiation was discovered that can degrade methyl orange effectively in aqueous solution.

Abstract
A microRNA (miRNA) nanomedicine PEG-PEI/miR-221/222 was synthesized based on PEGylated polyethylenimine PEG-PEI and used to transfect prostate cancer cells (PC-3) in vitro. Gel retardation assay confirmed the formation of nanomedicine, of which the zeta potential and particle size were determined by dynamic light scattering. Its cytotoxicity was analyzed by CCK-8 assay-while its transfection efficiency was analyzed by flow cytometry. Cell uptake and intracellular distribution of nanoparticles were evaluated using laser confocal microscopy. RT-PCR and western-blot assays were conducted to verify the regulation of SIRT1 target gene. We found that the properties of the nanocomplexes of miRNA and PEG-PEI depended on N/P ratios. At higher N/P ratio, accompanied by higher zeta potential and higher cytotoxicity, PEG-PEI is needed to completely condense the miRNA into small particles with uniform size distribution. Under an N/P ratio of 20, high transfection efficiency and low carrier cytotoxicity were obtained simultaneously in PC-3 cells in vitro. Consequently, the SIRT1 expression was up-regulated due to the nanoparticle-delivered miR-221/222, which resulted in effective inhibition of PC-3 cells. Our study revealed the PEG-PEI/miR-221/222 nanomedicine as a prospective alternative for treatment of advanced prostate cancer and also lays a foundation for future in vivo investigation.
Comparative sulfite assay by voltammetry using Pt electrodes, photometry and titrimetry: Application to cider, vinegar and sugar analysis
Authors: Pisoschi Aurelia Magdalena , Pop Aneta 
Published: December 2018

AbstractSulfite is a widely applied preservation agent, against oxidative decay in foodstuffs and beverages. Among the analytical methods applied, electrochemical techniques exploit its facility to undergo oxidation. This paper aims at the comparative investigation of the performances exhibited by three analytical methodologies: cyclic voltammetry at different Pt working electrodes, the volumetric method employing sodium thiosulfate as titrating agent and the photocolorimetric method relying on the reduction of Fe3+-orthophenanthroline complex by sulfite. The cyclic voltammetric assay was performed at Pt strip and Pt ring electrodes, by linearly sweeping the potential between -100 and 1,500 mV. The linear range corresponded to 7.5 mg L-1– 4.0 g L-1for Pt strip working electrode and to 15.5 mg L-1– 4.0 g L-1for Pt ring working electrode. Relative standard deviations smaller than 3% showed repeatability. RSD values smaller than 3% were also obtained in the photometric assay, but the latter was characterised by a narrower linear range. The Pt strip electrode allowed wider linear range and lower sensitivity, whereas the Pt ring electrode with Ag/AgCl reference in the same unit was characterised by better repeatability. Applications involved sulfite assay in vinegar, brown sugar and cider samples with consistency between cyclic voltammetry and titrimetry.

Authors: Wang Jiaoliang , Long Liping , Xiao Guing , Fang Fang 
Published: December 2018

AbstractCompounds Rh6G-1 and RhB-2 with a novel receptor composed of tri-oxygen atoms of amide groups were designed and synthesized as new reversible fluorescent sensors for Fe3+. The prominent features of the novel sensor Rh6G-1 include a large fluorescence turn-on response in essentially pure water at room temperature, high sensitivity, high selectivity, a limit of detection, cell membrane permeability, and low cytotoxicity. These desirable attributes enable us to successfully employ the new sensor Rh6G-1 for Fe3+ bioimaging in living cells.
Testing the symmetry of a dependence structure with a characteristic function
Authors: Bahraoui Tarik , Bouezmarni Taoufik , Quessy Jean-François 
Published: December 2018

AbstractThis paper proposes competing procedures to the tests of symmetry for bivariate copulas of Genest, Nešlehová and Quessy (2012). To this end, the null hypothesis of symmetry is expressed in terms of the copula characteristic function that uniquely determines the copula of a given bivariate population with continuous marginal distributions. Then, test statistics based on L2 weighted distances computed from an empirical version of the copula characteristic function are proposed. Their asymptotic behavior is derived under the null hypothesis as well as under general alternatives. In particular, it is established that these rank statistics behave asymptotically as first-order degenerate V-statistics under the null hypothesis and this large-sample representation is exploited in order to provide suitably adapted multiplier bootstrap versions for the computation of p-values. The simulations that are reported show that the new tests are more powerful than the competing methods based on the empirical copula introduced by Genest, Nešlehová and Quessy (2012).

Abstract
In this work, an optical hybrid communication system is proposed. It is a combination of diffused link (DL) configuration of free space optics (FSO) setup and fiber optic setup. It is a 16-channel dense wavelength division multiplexing (DWDM) system, with 400 Gbps/channel data rate. It uses dual polarization-quadrature phase shift keying (DP-QPSK) modulation technique for all the setups. Bit error rate (BER), eye diagram, quality actor (Q-factor), optical time domain reflectometer (OTDR), optical spectrum analyzer (OSA) signals are considered as performance parameters of the proposed system. It is found that the link distance is 340 m for DL setup and 1,000 km for fiber setup. The system will be very much useful for solving first mile, last mile problem with long distance optical communication applications in 5 G era.

Abstract
Laser direct writing is a well-established ablation technology for high-resolution patterning of surfaces, and since the development of additive manufacturing, laser processes have also appeared very attractive for the digital fabrication of three-dimensional (3D) objects at the macro-scale, from few millimeters to meters. On the other hand, laser-induced forward transfer (LIFT) has demonstrated its ability to print a wide range of materials and to build functional micro-devices. For many years, the minimum size of laser-printed pixels was few tens of micrometers and is usually organized in two dimensions. Recently, new approaches have been investigated, and the potential of LIFT technology for printing 2D and 3D sub-micrometer structures has become real. After a brief description of the LIFT process, this review presents the pros and cons of the different digital laser printing technologies in the aim of the additive nanomanufacturing application. The transfer of micro- and nano-dots in the liquid phase from a solid donor film appears to be the most promising approach to reach the goal of 3D nanofabrication, and the latest achievements obtained with this method are presented and discussed.

Authors: Bartmańska Agnieszka , Tronina Tomasz , Popłoński Jarosław 
Published: December 2018

Abstract
Microbial transformations of isoxanthohumol (1), a beer prenylated flavonoid, by 51 fungi were investigated. Many of the tested fungi cultures were capable of effective transformation of 1. Mucor hiemalis and Fusarium oxysporum converted isoxanthohumol (1) into isoxanthohumol 7-O-β-d-glucopyranoside (3) and (2R)-2″-(2″′-hydroxyisopropyl)-dihydrofurano[2″,3″:7,8]-4″,5-hydroxy-5-methoxyflavanone (4), respectively. No product was obtained in the transformation of 1 by Absidia glauca conducted in a phosphate buffer. In the same medium, Beauveria bassiana converted isoxanthohumol (1) to isoxanthohumol 7-O-β-d-4″′-O-methylglucopyranoside (2).

OBJECTIVES:
For decades, infants with Duarte galactosemia (DG) have been identified by newborn screening (NBS), but whether they should be treated with dietary restrictions of galactose has remained unknown. To clarify, we conducted a study of dietary and developmental outcomes in 206 children with DG (case patients) and 144 controls, all of whom were 6 to 12 years old.

METHODS:
We recruited case patients from states where they were identified by NBS; unaffected siblings served as controls. Diet in infancy was ascertained by retrospective parent surveys; developmental outcomes were assessed in 5 domains, yielding 73 outcome measures for each child. We divided subjects randomly into independent discovery (n = 87) and validation (n = 263) sets. We tested the discovery set to order the 73 outcome measures by ascending P values and tested the 10 outcomes with the lowest P values for possible association with DG in the validation set. We also tested these same 10 outcomes for possible association with milk exposure in infancy among case patients in the validation set.

RESULTS:
None of the 73 outcomes tested in the discovery set revealed significant association with DG, and none of the 10 outcomes tested in the validation set revealed either significant association with DG or significant association with milk exposure among children with DG.

CONCLUSIONS:
Through our results, we demonstrated that there were no significant differences in outcomes tested between case patients and controls or among case patients as a function of milk exposure in infancy. In this study, we provide a long-needed foundation of knowledge for health care providers, families, and NBS professionals seeking to make evidence-based decisions about DG.
Amor, humor: Noel Rosa e Oswald de Andrade

Published: December 2018

Este artigo propõe o estudo de algumas canções passionais de compositor Noel Rosa, sob a ótica da dualidade “amor/humor” apresentada no contexto das proposições estéticas da poesia Pau-Brasil, de Oswald de Andrade. Tais análises apontam para uma das marcas de confluência entre as obras dos dois autores, cujas linguagens aproximam a poesia da fala cotidiana, distanciando as formas poéticas da aura sublime e da retórica ornamental que costumavam caracterizar o canto e a escrita. Demonstra-se a astúcia criativa do Poeta da Vila, que, no casamento perfeito entre texto e melodia, cria sentidos inesperados nos quais o discurso amoroso é contaminado pela ironia e pelo humor. *** Love, humor: Noel Rosa and Oswald de Andrade ***This paper proposes the study of selected songs by Noel Rosa, from the “love/humor” duality perspective presented in the Pau-Brasil poetry aesthetic by Oswald de Andrade. Such analysis points out to one of the confluence marks between the work of the two artists, whose language approximate poetry and everyday speech, distancing the aura of sublime poetic forms from the ornamental rhetoric which used to characterize singing and writing. Therefore, we can see Rosa’s creative wit that, in the perfect partnership between text and melody, creates unexpected meanings in which love is contaminated by irony and humor.Keywords: song; poetry; humor; Noel Rosa; Oswald de Andrade.

Abstract: Dental anaesthesia is one of the most frequently performed medical procedures. Although the frequency of ocular complications is low, these can be alarming and can potentially give rise to medicolegal issues. Dentists and oral surgeons should be well-informed of these adverse reactions. Ophthalmologists and emergency physicians might be required for appropriate care of these patients. Fortunately, most ocular complications related to dental anesthesia are transient. Differential diagnosis includes stroke and intracranial hemorrhage and so vital signs are to be closely monitored. The planned surgical procedure can be carried out once the patient is fully informed and gave consent. The psychological aspect of such unexpected complication must be managed appropriately. We report a case with diplopia and ophthalmoplegia of a reversible and temporary nature. We also include a literature review of ophthalmologic complications after intraoral local anaesthesia in this paper. Orv Hetil. 2018; 159(52): 2212–2216.

Authors: STEFANIAK Anna , GRZESZCZUK Monika Elżbieta 
Published: December 2018

The introduction of edible flowers into our menu and their consumption significantly increases as a result of decorative, taste or aroma qualities. Current research on the chemical composition of edible flowers indicates a high content of vitamins, mineral compounds, essential oils, fibre, mucilage and other compounds characterized by a very high antioxidant activity. The aim of the experiment was to compare the nutritional value and antioxidant activity of three annual and two perennial ornamental plant species with edible flowers: Mimulus x hybridus L. ‘Magic Yellow’ and ‘Magic Red’, Antirrhinum majus L. ‘Cavalier’, Dianthus chinensis L. ‘Chianti’, Hemerocallis x hybrida Hort. and Monarda didyma L. Among the edible flower species compared in the study, M. didyma L. showed the highest nutritional value and antioxidant activity (DPPH and ABTS). While flowers of D. chinensis L. ‘Chianti’ were characterized by highest content of antioxidants such as L-ascorbic acid, total anthocyanins, total polyphenols and ferric reducing antioxidant power (FRAP), H. × hybrida and A. majus L. ‘Cavalier’ flowers – by the highest content of total soluble sugars and sugar/acid ratio, and M. × hybridus L. ‘Magic Red’ and ‘Magic Yellow’ – by the highest content of total carotenoids.
Contributions to the Classification of Capsicum annuum L. and Capsicum frutescens L. in West Africa Using Morphological Traits
Authors: OLATUNJI Tomi Lois , AFOLAYAN Anthony Jide 
Published: December 2018

In West Africa, the genus Capsicum is represented by two cultivated species namely C. frutescens and C. annuum with different varieties. However, the taxonomic identity of these two species has been unresolved because they are morphologically related. There has been considerable debate on their status as two separate species or just varieties of one species. The study was aimed at assessing the variability and relatedness among the four varieties of the two closely related Capsicum species in West Africa. The varieties used in this study are C. annuum var. abbreviatum, C. annuum var. acuminatum, C. annuum var. grossum and C. frutescens var. baccatum. The varieties were morphologically characterized using 80 quantitative and qualitative standard descriptors from seedling emergence to plant maturity. Data collected were subjected to statistical analysis using SPSS statistical package, descriptive statistics and cluster analysis. The results revealed overlapping similarities in the morphology of the four varieties. Classification analysis based on data collected showed two distinct clusters by grouping varieties sharing close phenotypic similarities into distinct cluster. The differences observed among the varieties majorly in flower and fruit traits do not provide enough evidence to conceive that the collections are two separate species. Our results therefore support the inclusion of C. frutescens var. baccatum as a variety of C. annuum. Additional comparative molecular profiling is needed to fully understand the phylogenetic relationship among the cultivated Capsicum species in this part of the world.
Effects of Vermicompost on Some Morphological, Physiological and Biochemical Parameters of Lettuce (Lactuca sativa var. crispa) under Drought Stress
Authors: KIRAN Sevinç 
Published: December 2018

Vermicompost can play an effective and important role in plant growth and development and also in reducing harmful effects of various environmental stresses on plants. The vermicompost fertilizer application was evaluated for the growth, physiological and biochemical parameters of lettuce (Lactuca sativa var. crispa) plants under drought stress conditions. Tests were carried out at different levels of vermicompost (0, 2.5 and 5%) and drought stress [no stress, moderate drought, and severe drought at 100, 50 and 25% of field capacity]. In comparison to control (vermicompost at 0%), lettuce plants treated with vermicompost at 2.5 or 5% had higher shoot height, shoot fresh weight, relative water content, stomatal conductance, chlorophyll a, chlorophyll b , total chlorophyll and carotenoid contents under moderate and severe drought stress conditions. Malondialdehyde (MDA) content and superoxide dismutase (SOD) and catalase (CAT) activities increased while plants under drought stress conditions. Application of vermicompost caused higher SOD and CAT enzyme activities and lower MDA content under drought stress. Enhancement in antioxidant enzyme activities as a result of vermicompost destroyed reactive oxygen species. Therefore, application of vermicompost under moderate and severe drought stress decreased MDA content in lettuce plant cells. Data indicated a positive effect of the vermicompost on the growth of lettuce under drought stress conditions.
Cloning and Functional Characterization of CsUGD2 in Cucumber (Cucumis sativus L.)
Authors: DUAN Yitong , ZENG Shuocheng 
Published: December 2018

UGD gene encodes UDP-glucose dehydrogenase (UGD) which is a key enzyme in the biosynthesis of cell wall, and it catalyses the irreversible oxidation of UDP-glucose (UDP-Glc) into UDP-glucuronic acid (UDP-GlcA). In cucumber, the expression level of CsUGD2 genes was higher in phloem tissues of pedicel and fruit than that in stalk. This study investigated the function of CsUGD2 in cucumber by different methods. Structure analysis indicated that CsUGD2 gene only has an exon with a length of 1,443 bp. Protein alignment suggested that UGD protein was highly conservative in different species. Phylogenetic analysis showed that CsUGD2 protein and CmoUGD2 protein form a same clade which is far away from UGDs in Arabidopsis. Real-time fluorescence quantitative analysis of CsUGD2 in different tissues of cucumber in the same period showed that CsUGD2 expressed highest in the root of cucumber. When we transformed CsUGD2 into wild type Arabidopsis, the roots of transgenic plants were shorter and the flowering time was delayed. These results suggested that CsUGD2 may play an important role in the development of cucumber roots and only act on the development of cucumber fruit when compared with other plants fruits. However, the role of CsUGD2 in regulating the growth and development process of cucumber need to further study.
