description: Copper(II) chelates of three unsymmetrical synthetic analogs of curcumin, namely (2E)-2-(4-hydroxy-3-methoxybenzylidene)-5-((E)-3-(4-hydroxy-3-methoxyphenyl)acryloyl)cyclopentanone(1), (2E)-2-(3,4-dihydroxybenzylidene)-5-((E)-3-(3,4-dihydroxyphenyl)acryloyl)cyclopentanone(2), and (2E)-2-(3,4-dimethoxybenzylidene)-5-((E)-3-(3,4-dimethoxyphenyl)acryloyl)cyclopeantanone(3) have been synthesized and characterized by physicochemical and spectroscopic methods. The ligands were in their enolic form and metal complexes have 1 : 2 metal:ligand stoichiometry. The DNA-binding properties of the ligands and their metal complexes were studied by absorption titrations, fluorescence quenching experiments, and viscosity measurements with calf-thymus DNA. The interactions of copper(II) complexes were higher than that of free ligands. The observed intrinsic binding constants reveal moderate interaction of copper(II) complexes with calf-thymus DNA. The binding involves intercalative mode through non-covalent interactions and produced conformational changes in the structure of DNA. The compounds were investigated for their possible cytotoxic and antitumor activities. All the compounds were cytotoxic towards Dalton’s lymphoma ascites cells. It was found that copper chelates are remarkably active compared to free curcumin analogs. Concentrations needed for 50% cell death were 10–22 μg mL−1 for copper complexes and 27–52 μg mL−1 for curcumin analogs. Copper complex of 2 with two hydroxyl groups in the phenyl ring was most active towards Dalton’s lymphoma ascites cells (increase in life span 77.91%). Copper(II) complex of 3, which possesses methoxy groups in the phenyl ring system, showed the lowest activity towards increase in lifespan of tumor-bearing mice (increase in lifespan 60.14%). Copper chelates of all curcuminoid analogs showed a significant reduction in solid tumor volume in mice.

description: Providing personalized recommendations for insurance products is particularly challenging due to the intrinsic and distinctive features of the insurance domain. First, unlike more traditional domains like retail, movie etc., a large amount of user feedback is not available and the item catalog is smaller. Second, due to the higher complexity of products, the majority of users still prefer to complete their purchases over the phone instead of online. We present different recommender models to address such data scarcity in the insurance domain. We use recurrent neural networks with 3 different types of loss functions and architectures (cross-entropy, censored Weibull, attention). Our models cope with data scarcity by learning from multiple sessions and different types of user actions. Moreover, differently from previous session-based models, our models learn to predict a target action that does not happen within the session. Our models outperform state-of-the-art baselines on a real-world insurance dataset, with ca. 44K users, 16 items, 54K purchases and 117K sessions. Moreover, combining our models with demographic data boosts the performance. Analysis shows that considering multiple sessions and several types of actions are both beneficial for the models, and that our models are not unfair with respect to age, gender and income.

description: Three dinuclear copper(II) complexes, [Cu2(L1)2(μ-ox)](ClO4)2⋅2(CH3CN), [Cu2(L2)2(μ-ox)](ClO4)2⋅H2O, and [Cu2(L3)2(μ-ox)](ClO4)2 where ox = oxalato; L = N,N-dimethyl,N′-benzylethane-1,2-diamine, L1, N,N-diethyl,N′-benzylethane-1,2-diamine, L2, N,N-diisoprophyl,N′-benzylethane-1,2-diamine, L3, were prepared and characterized by elemental analyses, spectral (IR, UV–Vis) data and molar conductance measurements. The crystal structures of [Cu2(L1)2(μ-ox)](ClO4)2⋅2(CH3CN) and [Cu2(L3)2(μ-ox)](ClO4)2 have been determined by single-crystal X-ray analysis. Solvatochromic behaviors were investigated in various solvents, showing positive solvatochromism. The effect of steric hindrance around the copper ion imposed by N-alkyl groups of the diamine chelates on the solvatochromism property of the complexes is discussed. Solvatochromism was also studied with different solvent parameter models using stepwise multiple linear regression method.

description: Background: Solid tumors are known to be spatially heterogeneous. Detection of treatment-resistant tumor regions can improve clinical outcome, by enabling implementation of strategies targeting such regions. In this study, K-means clustering was used to group voxels in dynamic contrast enhanced magnetic resonance images (DCE-MRI) of cervical cancers. The aim was to identify clusters reflecting treatment resistance that could be used for targeted radiotherapy with a dose-painting approach. Material and methods: Eighty-one patients with locally advanced cervical cancer underwent DCE-MRI prior to chemoradiotherapy. The resulting image time series were fitted to two pharmacokinetic models, the Tofts model (yielding parameters Ktrans and νe) and the Brix model (ABrix, kep and kel). K-means clustering was used to group similar voxels based on either the pharmacokinetic parameter maps or the relative signal increase (RSI) time series. The associations between voxel clusters and treatment outcome (measured as locoregional control) were evaluated using the volume fraction or the spatial distribution of each cluster. Results: One voxel cluster based on the RSI time series was significantly related to locoregional control (adjusted p-value 0.048). This cluster consisted of low-enhancing voxels. We found that tumors with poor prognosis had this RSI-based cluster gathered into few patches, making this cluster a potential candidate for targeted radiotherapy. None of the voxels clusters based on Tofts or Brix parameter maps were significantly related to treatment outcome. Conclusion: We identified one group of tumor voxels significantly associated with locoregional relapse that could potentially be used for dose painting. This tumor voxel cluster was identified using the raw MRI time series rather than the pharmacokinetic maps.

description: Adapting a counterexample recently proposed by J.L. Mancilla-Aguilar and H. Haimovich, we show here that, for time-delay systems, global asymptotic stability does not ensure that solutions converge uniformly to zero over bounded sets of initial states. Hence, the convergence might be arbitrarily slow even if initial states are confined to a bounded set.

description: [RuIII(EDTA)(H2O)]− (EDTA4− = ethylenediaminetetraacetate) catalyzes the oxidation of biological thiols, RSH (RSH = cysteine, glutathione, N-acetylcysteine, penicillamine) using H2O2 as precursor oxidant. The kinetics of the oxidation process were studied spectrophotometrically as a function of [RuIII(EDTA)(H2O)]−, [H2O2], [RSH], and pH (4–8). Spectral analyses and kinetic data are suggestive of a catalytic pathway in which the RSH reacts with [RuIII(EDTA)] catalyst complex to form [RuIII((EDTA)(SR)]2− intermediate species. In the subsequent reaction step the oxidant, H2O2, reacts directly with the coordinated S of the [RuIII((EDTA)(SR)]2− intermediate leading to formation of the disulfido (RSSR) oxidation product (identified by HPLC and ESI-MS studies) of thiols (RSH). Based on the experimental results, a working mechanism involving oxo-transfer from H2O2 to the coordinated thiols is proposed for the catalytic oxidation.

description: The objective of our study is to observe dynamics of multiple substances in vivo with high temporal resolution from multi-spectral magnetic resonance spectroscopic imaging (MRSI) data. The multi-spectral MRSI can effectively separate spectral peaks of multiple substances and is useful to measure spatial distributions of substances. However it is difficult to measure time-varying substance distributions directly by ordinary full sampling because the measurement requires a significantly long time. In this study, we propose a novel method to reconstruct the spatio-temporal distributions of substances from randomly undersampled multi-spectral MRSI data on the basis of compressed sensing (CS) and the partially separable function model with base spectra of substances. In our method, we have employed spatio-temporal sparsity and temporal smoothness of the substance distributions as prior knowledge to perform CS. The effectiveness of our method has been evaluated using phantom data sets of glass tubes filled with glucose or lactate solution in increasing amounts over time and animal data sets of a tumor-bearing mouse to observe the metabolic dynamics involved in the Warburg effect in vivo. The reconstructed results are consistent with the expected behaviors, showing that our method can reconstruct the spatio-temporal distribution of substances with a temporal resolution of four seconds which is extremely short time scale compared with that of full sampling. Since this method utilizes only prior knowledge naturally assumed for the spatio-temporal distributions of substances and is independent of the number of the spectral and spatial dimensions or the acquisition sequence of MRSI, it is expected to contribute to revealing the underlying substance dynamics in MRSI data already acquired or to be acquired in the future.
Secure Routing for Mobile Ad hoc Networks

description: The emergence of the Mobile Ad Hoc Networking (MANET) technology advocates self-organized wireless interconnection of communication devices that would either extend or operate in concert with the wired networking infrastructure or, possibly, evolve to autonomous networks. In either case, the proliferation of MANET-based applications depends on a multitude of factors, with trustworthiness being one of the primary challenges to be met. Despite the existence of well-known security mechanisms, additional vulnerabilities and features pertinent to this new networking paradigm might render such traditional solutions inapplicable. In particular, the absence of a central authorization facility in an open and distributed communication environment is a major challenge, especially due to the need for cooperative network operation. In particular, in MANET, any node may compromise the routing protocol functionality by disrupting the route discovery process. In this paper, we present a route discovery protocol that mitigates the detrimental effects of such malicious behavior, as to provide correct connectivity information. Our protocol guarantees that fabricated, compromised, or replayed route replies would either be rejected or never reach back the querying node. Furthermore, the protocol responsiveness is safeguarded under different types of attacks that exploit the routing protocol itself. The sole requirement of the proposed scheme is the existence of a security association between the node initiating the query and the sought destination. Specifically, no assumption is made regarding the intermediate nodes, which may exhibit arbitrary and malicious behavior. The scheme is robust in the presence of a number of non-colluding nodes, and provides accurate routing information in a timely manner.

description: Si(111)−(5×2)−Au represents a prototype system for an adsorbate-induced spontaneous symmetry break by formation of quasi-one-dimensional atomic chains that are metallic. Surprisingly, the geometric structure of these chains is still under debate. In this paper, we show that examination of the unoccupied band structure by plasmon spectroscopy in combination with low energy electron diffraction contains sufficient information to discriminate between suggested models, favoring an optimal concentration of 6 atoms per (5×2) unit cell. Furthermore, we tested the stability of this structure and found that higher concentrations of Au tend to destabilize the single-domain structure on the slightly misoriented Si(111) surface.

The riding horse movement not only gone viral by a short clips, but in return being used as an internet meme such as gif or short cover clips. "Gangnam Style" debuted at number one on South Korea's Gaon Chart─National chart for music in South Korea similar to the Billboard charts of the United States and the Oricon charts of Japan. The song and its music video went viral and became a global smash hit with more than 1 billion hits and became the most-watched music video on YouTube. Anyhow, K-Pop was already blooming even before Gangnam Style debuted, caught in gigantic crowds’ attention especially in Japan and across South East Asia since the early 2000s. And since the late 2000s, it has been known by not only the rest of Asia but also the world, which includes the unpredictable regions such as the Middle East.

description: Background. Chronic obstructive pulmonary disease is a progressive and disabling condition which is common and is associated with significant morbidity and mortality, despite medical treatment and pulmonary rehabilitation. Endoscopic lung volume reduction (ELVR) therapy is a relatively new treatment option for a select group of sufferers of severe emphysema in Australia. 
The aim of this thesis is to address many of the unanswered questions in the role, mechanisms of action and effects of ELVR in COPD, and to apply the lessons learnt from international studies to the Australian setting, using local resources and expertise. 
Methods. Patients with severe heterogeneous emphysema were prospectively recruited and underwent ELVR procedures using endobronchial valves or intrabronchial valves. Clinical data were collected at baseline, one month, three months and twelve months to investigate the effects of ELVR on lung function, exercise capacity, quality of life, ventilation and perfusion, cardiac parameters and small airway physiology. 
Results. Sixty one patients were recruited and underwent ELVR. Targeted lobe atelectasis was an important predictor of lung function improvement, rendering a significant increase in FEV1 (+9.6%, p<0.01) and a reduction in RV (-6.4%, p<0.05) at three months; these changes were sustained for 12 months. Improvements in six-minute walk distances (+77.4 metres, p<0.01) and quality of life scores (-11 units, p<0.01) were more notable than changes in FEV1 (+6.1%, p=NS) at 12 months. There were reversible complications including pneumothoraces (n=3), valve revision (n=22) and valve removal (n=8). There were 2 peri-procedural deaths. 
In our planar VQ studies of both upper and lower lobe treated patients, we found that regional ventilation and perfusion were redistributed to the contralateral upper zones. Associated improvements in gas transfer factor were observed in subjects with upper lobe treatment. Subsequent data obtained using VQ-SPECT/CT were also consistent with the above findings of VQ redistribution to the contralateral upper lobe; these results were also correlated with improvements in FEV1 (r=0.61, p<0.01). By contrast, there were no such improvements in pulmonary hypertension at 12 months in our cohort. 
Reduced gas trapping with ELVR was correlated with an improvement in FEV1 (r=-0.83, p=0.01) and a reduction in resistance of the respiratory system (r=0.71, p=0.03); whilst improved reactance was correlated with an improvement in six-minute walk distance (r=0.83, p=0.04). 
Conclusions. Our studies confirmed the efficacy and safety profile of ELVR in the Australian setting. In addition, the studies provided insight into the mechanisms, physiological basis and clinical outcomes of ELVR in COPD.

description: Background: The Postgraduate Hospital Educational Environment Measure (PHEEM) is a highly reliable and valid instrument to measure the educational environment during post graduate medical training. This review extends earlier reports by evaluating the extant adoption of PHEEM in various international clinical training sites, and its significant correlations in order to expand our understanding on the use of PHEEM and facilitate future applications and research. Method: A systematic literature review was conducted on all articles between 2005 and October 2015 that adopted and reported data using the PHEEM. Results: Overall 30 studies were included, encompassing data from 14 countries internationally. Notable differences in the PHEEM scores were found between different levels of training, disciplines, and clinical training sites. Common strengths and weaknesses in learning environments were observed and there were significant correlations between PHEEM scores and In-Training Exam (ITE) performance (positive correlation) and level of burnout (negative correlation), respectively. Conclusions: PHEEM is widely adopted in different learning settings, and is a useful tool to identify the strengths and weaknesses of an educational environment. Future research can examine other correlates of PHEEM and longitudinal changes in interventional studies.

description: A screening of Chinese medicinal herbs and wild plants for agrochemicals was carried out; the essential oil of Glycosmis lucida leaves was found to possess significant repellent activity against Tribolium castaneum and Liposcelis bostrychophila. It was found that the main components included elixene (19.81%), spathulenol (10.68%), anethole (12.05%), verbenone (10.32%) followed by β-caryophyllene (6.87%). The essential oil, anethole and verbenone were strongly repellent against T. castaneum (96, 86 and 94%, respectively, at 15.73 nL cm−2) and L. bostrychophila (100, 68 and 72%, respectively, at 31.58 nL cm−2) after a 2h treatment. The results indicate that anethole and verbenone had the potential to be developed as natural repellents for control of stored product insects.

КОШКИ

description: Как известно, почки это жизненно важные органы, выполняющие множество функций. За счет почек в организме поддерживается правильный баланс жидкости и электролитов, синтезируется ряд веществ. С помощью почек организм избавляется от продуктов азотистого обмена, органических кислот, ряда чужеродных веществ, утилизирует гастрин и другие гормоны. Одной из наиболее встречаемых в практике патологии кошек является хроническая недостаточность почек, при которой почки плохо выполняют свою выделительную функцию или перестают ее выполнять совсем. Это коварное заболевание, отражается на работе практически всех систем организма, а клинически проявляется только тогда, когда уже поражено 65-80% почечной ткани. И поэтому чем раньше будет поставлен диагноз, тем дольше проживет животное после соответствующей терапии. В настоящее время в ветеринарных аптеках предлагают большое количество лекарственных средств для лечения хронической почечной недостаточности кошек, но современная терапия направлена на компенсацию почечной недостаточности, полностью вылечить животное от заболевания нельзя. Данная работа направлена на изучение эффективности поддерживающей терапии.

description: The montane forests of northern Mozambique’s isolated massifs are inhabited by numerous range-restricted and threatened bird species, but until recently were extremely little-known. We report on a first avifaunal survey of the isolated montane habitats of Mt Mecula (1 442 m), Niassa National Reserve, notable as the only currently protected montane area in northern Mozambique. Mount Mecula’s moist forest is small (approximately 136 ha in total) and patchy, and although known botanically to have some montane affinities, was found to support an avifauna more typical of riparian forests of medium to low altitude. The only montane forest species recorded was Lemon Dove Aplopelia larvata. Other montane elements included Vincent’s Bunting Emberiza (capensis) vincenti, one of six species recorded new to the Niassa National Reserve list. Overall, it appears that despite its intermediate location, Mt Mecula does not represent a biogeographical ‘stepping stone’ for montane forest bird species. This probably owes to its remoteness from the Eastern Arc Mountains of Tanzania to the north and the massifs of other parts of northern Mozambique, to the south and west.

description: В статье рассматривается влияние сахарозы на морфологический и химический состав мяса гибридных свиней канадской селекции. Опыт проведён на базе ООО «Оренбургский бекон» Оренбургской области. В период отъёма поросят от свиноматок были сформированы четыре группы боровков по 20 гол в каждой. Сахарозу вводили в дополнение к основному рациону с 25 сут. возраста поросят до завершения периода выращивания 105 сут. Поросята контрольной гр. получали основной рацион хозяйства. Молодняку I, II и III опытных гр. дополнительно к рациону задавали сахарозу в дозе 10, 20 и 30 г соответственно на гол. в сут. Анализ полученных данных свидетельствует о том, что применение сахарозы в дозе 20 гр/гол в сутки с 25 по 105 сут. способствует повышению качества мясной продукции, увеличивая массу охлаждённой туши на 4,4 кг, массу мяса в туше на 5 кг и снижая содержание сала в ней на 0,6 кг. Применение сахарозы в вышеобозначенной дозе способствует повышению протеина в шейной части на 7,9%; в лопатке на 5,9% и в бедре на 5,3%; сухого вещества в шейной части на 4,4 %; в лопатке на 2,2% и в бедре на 0,3% и снижает содержание влага в шейной части на 4,4%; в лопатке на 2,2% и в бедре на 0,3%; жира в шейной части на 3,4%; в лопатке на 3,8% и в бедре на 5,2%.

description: В статье рассмотрены практико-ориентированные основы применения минеральных азотных и калийных удобрений на различных по обеспеченности подвижными формами фосфора фонах (пониженный, средний и повышенный). Приведены результаты влияния удобрений на продуктивность галего-кострецовых травосмесей на черноземах выщелоченных в условиях северной лесостепной зоны Западной Сибири. Травосмесь галеги с кострецом на фоне с низким содержанием подвижного фосфора по продуктивности не уступает одновидовым посевам галеги, сбор кормовых единиц составил 4,6 т/га, переваримого протеина 1,00 т/га и обменной энергии 56,9 ГДж/га. При оптимизации питания фосфором и минимальных дозах азотных удобрений (по 30 кг д.в. под каждый укос) для усиления фитоценотической активности костреца продуктивность травосмеси возросла до 6,36 т/га кормовых единиц, 1,3 т/га переваримого протеина и 84,7 ГДж/га обменной энергии.

description: Plant chitinases play diverse roles including defense against pathogenic fungi. Using reverse-transcription quantitative PCR analysis, we found that six chitinase (PpChi) genes and two genes for chitin elicitor receptor kinases (PpCERKs) are expressed at considerable levels in the moss Physcomitrella patens subsp. patens. The expressed PpChis belonged to glycoside hydrolase family 19 (class I: PpChi-Ia and -Ib; class II: PpChi-IIa and -IIc; and class IV: PpChi-IV) and to glycoside hydrolase family 18 (class V: PpChi-Vb). Treatment with chitin tetramer or hexamer increased the expression of class I and IV PpChi genes and decreased that of class II PpChi genes. Recombinant PpChi-Ia, PpChi-IV, and PpChi-Vb were characterized. PpChi-IV exhibited higher activity against chitin tetramer and pentamer than PpChi-Ia did. PpChi-Vb showed transglycosylation activity and PpChi-Ia inhibited fungal growth. These results suggest that chitinases of different classes play different roles in defense mechanism of moss plant against fungal pathogens. Possible roles of each class of chitinase and chitin elicitor receptor kinase (CERK) for self-defense against pathogenic fungi in moss plant.
