Published: December 2017

Nowotwory nadal stanowią jedną z głównych przyczyn śmiertelności w populacji światowej, a długotrwałe ich leczenie jest trudne i wysoce problematyczne, pomimo znacznego pogłębienia wiedzy z zakresu ich biologii. Obecnie wykorzystywane metody terapeutyczne cechują się wysoką toksycznością, tym samym często udaremniając skuteczne wyleczenie i pogarszając jakość życia chorych. Z tego względu wzrasta zainteresowane środkami, które mogłyby wzmocnić skuteczność konwencjonalnej terapii lub ograniczyć występowanie poważnych skutków ubocznych. Przykładem takiej substancji jest fukoidyna - sulfonowany fukan pochodzenia naturalnego, pozyskiwany z alg i brunatnic. Istnieją liczne doniesienia potwierdzające jej efekty terapeutyczne obejmujące właściwości przeciwnowotworowe, przeciwwirusowe oraz immunomodulujące. Poniższa praca zawiera opis efektów terapeutycznych wywoływanych przez fukoidynę wyekstrahowaną z różnych gatunków alg w poszczególnych modelach nowotworów. Praca uwzględnia poznane dotychczas i proponowane mechanizmy indukcji efektów przeciwnowotworowych oraz krytyczną ocenę ograniczeń fukoidyny jako potencjalnego środka wspomagającego w terapii onkologicznej.
Review and comparison of performance indices for automatic model induction
Authors: Chadalawada Jayashree , Babovic Vladan 
Published: December 2017

Abstract
One of the more perplexing challenges for the hydrologic research community is the need for development of coupled systems involving integration of hydrologic, atmospheric and socio-economic relationships. Given the demand for integrated modelling and availability of enormous data with varying degrees of (un)certainty, there exists growing popularity of data-driven, unified theory catchment scale hydrological modelling frameworks. Recent research focuses on representation of distinct hydrological processes using mathematical model components that vary in a controlled manner, thereby deriving relationships between alternative conceptual model constructs and catchments’ behaviour. With increasing computational power, an evolutionary approach to auto-configuration of conceptual hydrological models is gaining importance. Its successful implementation depends on the choice of evolutionary algorithm, inventory of model components, numerical implementation, rules of operation and fitness functions. In this study, genetic programming is used as an example of evolutionary algorithm that employs modelling decisions inspired by the Superflex framework to automatically induce optimal model configurations for the given catchment dataset. The main objective of this paper is to identify the effects of entropy, hydrological and statistical measures as optimization objectives on the performance of the proposed approach based on two synthetic case studies of varying complexity.
A total cost minimization control for wastewater treatment process by using extremum seeking control
Authors: Yamanaka Osamu , Onishi Yuuta , Namba Ryo , Obara Takumi , Hiraoka Yukio 
Published: December 2017

Abstract
This paper presents a real-time optimal control scheme based on a total cost index (TCI) by using the so-called extremum seeking control (ESC). The ESC searches the minimum value of a given performance index where the TCI consisting of the operational cost and the effluent quality cost is used as the index. An improved ESC is proposed where a transformed TCI by monotonically increasing function is utilized to improve the convergence property of the ESC while keeping the argument of the optimal point invariant. The feasibility of the ESC is tested for two types of pseudo-anaerobic-oxic process control: one is the return sludge recycle ratio control, and the other is the aeration control for an alternate zone which can be anaerobic or aerobic depending on the influent condition. Simulation study illustrates that the proposed ESC is able to find a near optimal point successfully and the TCI can be reduced by about 2.7 to 3.8% compared with that of a typical operating condition.
Solid–liquid separation of an effluent produced by a fixed media biofilm reactor
Authors: Patry Bernard , Boutet Étienne , Baillargeon Serge , Lessard Paul 
Published: December 2017

Abstract
An experimental study dedicated to the characterization of the settleability of solids produced in immersed fixed media biofilm reactors has been carried out. The influence of operating temperature (0.1 to 16 °C) and surface organic loading rate (OLR) (0.4 to 10 g of soluble carbonaceous BOD5 per m2 of media per day) on settleable solids quantities, particle size distributions (PSD) as well as flocs morphology was evaluated. Results have shown that the OLR has no statistically significant influence on the settleability of the suspended solids. However, the operating temperature was identified as a factor that significantly influences the settling potential. The highest operating temperatures (14–16 °C) were related to the worst settling performances. On the other hand, the best settling performances were observed at intermediate operating temperatures (around 10 °C). The latter conditions were also associated with the largest fractions of large particles (&gt;100 μm) in the effluent. Differences in PSD were found to be well correlated with settling performances. Part of the performance results variability which cannot be explained by differences in PSD can potentially be attributed to differences in flocs morphology (compactness).
δ13CDIC tracing of dissolved inorganic carbon sources at Three Gorges Reservoir, China
Authors: Wu Qixin , Han Guilin 
Published: December 2017

AbstractIn order to understand water chemistry after impoundment of the Three Gorges Reservoir (TGR), the authors assessed the hydrogeochemical parameters (water temperature, pH, conductivity, dissolved O2), major element composition, and the carbon stable isotopic value of dissolved inorganic carbon (δ13CDIC) in summer and winter at various depths in the water column at TGR in 2009. In reservoir water, the DO values are lower in winter than in summer, but the pH values and conductivity values are higher. Ca2+ and Na+ are the dominant cations and HCO3− and SO42− are the dominant anions. In surface waters, the δ13CDIC values are more negative in summer than they are in winter, whereas the dissolved inorganic carbon (DIC) concentrations are relatively lower. In the water column, the DIC and δ13CDIC values do not change significantly with water depth or seasons. The DIC content shows a dilution effect in summer and is not modified by phytoplanktonic activity or photosynthesis. Even after the dam obstructed flow, the chemical profile of water in TGR is similar to that of the natural rivers before impoundment. Therefore, in this study, the water at TGR still had riverine characteristics and was still a heterotrophic system.

Authors: Tiwari Arunendera Kumar , Jain Tripti A. , Choubey Sonal , Bajpai Parmendra Kumar 
Published: December 2017

Background:
Metal chalcogenide nanomaterials represent an important group of efficient
materials, in which the subtle variations in shape, size and phase of nano-powders resulted in physical
properties (e.g., electronic and optical) differing from their bulk counterparts, which makes them
useful materials for various technological devices.

Objective:
Synthesis and growth of chalcogenide nano powders from novel single source molecular
precursors (i.e., Cd(II) bis-(aminopropane) selenide, Cd(II) bis-(aminoethane) telluride) for the production
of cadmium chalcogenide (CdE, E= Se/Te) at nano scale.

Method:
Single source molecular precursor inserted in quinoline, acting as a coordinating solvent at
suitable temperature, yielded vacuum dried powders of CdSe and CdTe nanomaterials.

Results:
The average particle size was estimated as CdSe ≈ 3 nm, and CdTe ≈ 29 nm from powder
X-ray diffraction pattern of synthesized nanoparticles. The produced nanomaterials possess optical
properties and calculated energy band gap of nanoparticles as CdTe = 5.2 eV and CdSe = 4.0 eV
from UV-Visible spectra.

Conclusion:
The economical, harmless single source molecular method may be a striking technique
to fabricate metal chalcogenide nanoparticles.

A dimensão afetiva na interação plurilingue: Dinâmicas de negociação de imagens e estereótipos na interação romanófona em chat
Authors: Melo-Pfeifer Sílvia , Araújo e Sá Maria Helena Almeida Beirão 
Published: December 2017

Tendo em conta a relevância da Internet ao nível do contacto intercultural e plurilingue, e definindo-se os espaços de comunicação como lugares de emergência e de negociação de imagens acerca do Outro, analisaremos um corpus constituído por interações plurilingues romanófonas em chat, com vista ao estudo da dinâmica das imagens e estereótipos nessa situação de comunicação. Tentaremos desocultar e analisar barreiras à comunicação intercultural, algumas utopias acerca dela (em particular, o recurso a uma língua franca como solução para os problemas comunicativos) e ainda facilidades propulsoras da interação, como a relação afetiva com as línguas, os locutores e a situação de comunicação. A discussão dos dados permitirá evidenciar como as imagens e os estereótipos cruzados de uns locutores em relação aos outros, às suas línguas e culturas emergem na interação, como estimulam e alimentam a conversação e como desencadeiam momentos "felizes" de comunicação plurilingue.Palavras-chave: Comunicação eletrónica; Intercompreensão; Imagens; Estereótipos ABSTRACTGiven the importance of the Internet as a contact tool at an intercultural and multilingual level, and considering a definition of communication spaces as places where images about the Other emerge and are negotiated, we will analyze a corpus of plurilingual interactions in chat conversations (in Romance Languages), in order to study the dynamics of the images and stereotypes in this communication situation. We will attempt to uncover barriers to intercultural communication, expose some utopias about it (like the use of a lingua franca as a solution to communication problems) and discover the possibilities propelling interaction, such as an affective relationship with the languages, the speakers and the communication situation. Data discussion will allow us to demonstrate how crossed images and stereotypes of the speakers towards others, their languages and cultures emerge in the interaction, how they feed and stimulate conversation and how they trigger ‘happy’ moments of plurilingual communication.Keywords: Electronic communication; Intercomprehension; Images; Stereotypes

Authors: Tasić Ivan S. , Djordjević Dragan , Kostić Svetlana 
Published: December 2017

Finding the arrythmogenic potential in patients with arterial hypertension as well as its correlation with left ventricular hypertrophy (LVH), and its type and degree. The research included 109 hypertensive patients (pts) (54 male and 55 female), 54.2 ± 7.9 years old without symptomatic coronary disease, myocardial infarction and systolic dysfunction. All the pts had a clinical examination, ECG, 24 h Holter monitoring with Lown classification of ventricular arrhythmias, an echocardiogram with left ventricular mass index (LVMI) and a specific type of LVH. QT interval dispersion (QTd) was calculated on 12 leads standard ECG. 75 pts had LVH (LVMI: 172.6 ± 42.95 g/m2) while 35 pts were without LVH (109.3 ± 15.9 g/m2). Non sustained ventricular tachycardia was registered in 13 pts (17.6%) with LVH and 1 female patient without LVH (2.9%). Patients with VT had a considerably higher ILVM (214.9 ± 6.8 vs. 151.9 ± 47.2 g/m2) than the average and higher QTd (73.7 ± 19.1 vs. 55.2 ± 20.2). VT was registered in 3/19 (15.8%) with eccentric nedilated type LVH, 6/38 (15.8%) with concentric LVH, 1/11 (9.1) (disproportional septal LVH) and 3/5 ( 60%) with dilated LVH. Univariate analysis showed a considerable correlation between the degree of arrhythmias and ILVM (p<0.001) and QTd (p=0.012). Ventricular arrhythmias in patients with arterial hypertension are considerably correlated to the degree of LVH expressed in ILVM and QTd.
Análisis del uso de antibióticos en antibiogramas de urocultivos realizados por un laboratorio clínico de la región centro-occidental de Colombia
Authors: Rodríguez-Salazar Carlos , Recalde-Reyes Delia , Padilla-Sanabria Leonardo 
Published: December 2017

Introducción: Los antibióticos son moléculas bactericidas/bacteriostáticas que controlan infecciones bacterianas, su uso incorrecto favorece multirresistencia o falla terapéutica en el caso de cepas bacterianas naturalmente resistentes, generando así un riesgo para la salud. Objetivo: Analizar el uso de antibióticos en antibiogramas de urocultivos realizados por un laboratorio clínico (región centro-occidental, Colombia). Materiales y métodos: Estudio descriptivo-retrospectivo. Se tomaron datos de urocultivos y antibiogramas realizados entre abril de 2014 a junio de 2015 por un laboratorio clínico de la región centro-occidental de Colombia. Los datos obtenidos fueron confrontados con los protocolos descritos por el Instituto Nacional de Salud de Colombia. Resultados: Se analizaron 1815 reportes de urocultivos y antibiogramas, identificando 18 especies bacterianas. En el 22,3%(403) de casos se evaluaron y reportaron antibióticos sobre microorganismos naturalmente resistentes. Pseudomonas aeruginosa presentó mayor resistencia, el antibiótico con mayor resistencia fue ácido nalidíxico (66,7%). Conclusión: El estudio mostró que existe un problema en cuanto al manejo, reporte e interpretación de antibiogramas frente a microorganismos naturalmente resistentes, que podría favorecer el desarrollo de multirresistencia en microorganismos sensibles de la flora bacteriana. Una revisión de la bibliografía nacional e internacional, mostró reportes similares; ningún autor menciona resistencias intrínsecas, por lo que los datos de antibiótico resistencia serían sobreevaluados.

OBJECTIVE
Gut microbiota represent a potential novel target for future prediabetes and type 2 diabetes therapies. In that respect, niacin has been shown to beneficially affect the host-microbiome interaction in rodent models.

RESEARCH DESIGN AND METHODS
We characterized more than 500 human subjects with different metabolic phenotypes regarding their niacin (nicotinic acid [NA] and nicotinamide [NAM]) status and their gut microbiome. In addition, NA and NAM delayed-release microcapsules were engineered and examined in vitro and in vivo in two human intervention studies (bioavailability study and proof-of-concept/safety study).

RESULTS
We found a reduced α-diversity and Bacteroidetes abundance in the microbiome of obese human subjects associated with a low dietary niacin intake. We therefore developed delayed-release microcapsules targeting the ileocolonic region to deliver increasing amounts of NA and NAM to the microbiome while preventing systemic resorption to avoid negative side effects (e.g., facial flushing). In vitro studies on these delayed-release microcapsules revealed stable conditions at pH 1.4, 4.5, and 6.8, followed by release of the compounds at pH 7.4, simulating the ileocolonic region. In humans in vivo, gut-targeted delayed-release NA but not NAM produced a significant increase in the abundance of Bacteroidetes. In the absence of systemic side effects, these favorable microbiome changes induced by microencapsulated delayed-release NA were associated with an improvement of biomarkers for systemic insulin sensitivity and metabolic inflammation.

CONCLUSION
Targeted microbiome intervention by delayed-release NA might represent a future therapeutic option for prediabetes and type 2 diabetes.
