Efeito do nível de energia metabolizável da dieta sobre a composição de carcaça de frangos de corte de três diferentes linhagens.

ABSTRACT : The objective of this study was to evaluate the effect of diet energy level over carcass composition of broilers from three different commercial genetics. A completely randomized design was used, and treatments followed a factorial design with three dietary energy values (low, medium and high) and three genetics (A, B and C). Percentages of fat, protein, water and collagen in the carcass were evaluated at 42 days old. The data was submitted to analysis of variance and compared by Tukey test with 5% of probability. There was no interaction between energy and genetic (P>0,05). The genetics differed by carcass fat and protein values. Low energy diet resulted in higher fat percentage, while high diet energy improved carcass protein and water content. The use of high energy diets allowed for better expression of broilers? genetic potential for muscular tissue deposition. Resumo: Na producao avicola atual, alem de otimo peso de abate e melhor conversao alimentar, tem se buscado qualidade na composicao da carcaca, visando atender as exigencias do mercado consumidor. A selecao genetica para rapido crescimento leva a adocao de novos criterios de manejo e nutricao para maximizar o bem estar animal, produtividade e otimizar custos, bem como gerar produtos de qualidade. Estudos demonstram que o nivel energetico da dieta e um fator de forte influencia sobre a qualidade da carcaca de frangos e que niveis maiores de energia na dieta podem levar a maior deposicao de gordura abdominal (Barbosa et al., 2008; Rosa et al., 2007; Meza et al., 2015). O objetivo do estudo foi avaliar o efeito do consumo de energia sobre a composicao de carcaca de frangos de corte machos de tres diferentes linhagens.
The Effect of Entrepreneurial Orientation on Business Performance: A Comparative Study of Necessity and Opportunity Entrepreneurs by Gender

Entrepreneurship is known, contribute to the economic growth locally as well as globally. To make entrepreneurship play its economic role, entrepreneurs are oriented by different factors and perform differently in their business. This lead the researchers to investigate the entrepreneurial orientation considering necessity and opportunity factors among women and men business owners and their owned businesses in Huye District. This was done to find out the effect of such orientation on their business performance and to examine the significance of cross-gender differences with regard to the variables under study. For achieving the above objectives; structured questionnaire and documentary review techniques were used to collect data. From total population of 1787 business owners identified from 11 sectors in Huye District, researchers sampled 327 respondents. Random and convenience sampling techniques were used. The results showed that both males and females are more opportunity oriented than necessity oriented. Study shows that business owned by males perform better than business owned by females regarding both financial and non-financial performance aspects. It was also found out that there are no significant differences in both levels of entrepreneurial orientation and business performance across gender. Correlation analysis revealed a significant relationship between entrepreneurial orientation of women and men business owners and their business performance. Based on these findings, it recommends that the Government of Rwanda (GoR) should focus training and sensitization for women to increase their involvement in business and improve the performance of existing women business owners. Improving entrepreneurship program by MINEDUC should also be given consideration especially at primary and secondary levels/educations to prepare potential entrepreneurs.
Chimie des pigments anthocyaniques. 4. Spectre d'absorption UV-visible de la forme chalcone de la glucoside-3 malvidine

Les anthocyanes existent, en milieu aqueux acide, sous plusieurs formes en equilibre : la base quinonique, le cation flavylium, le carbinol et la chalcone. Du tait de sa faible abondance et du fait de la presence des trois autres structures, l'observation spectroscopique de la forme chalcone est diffi- cile. Nous donnons ici une methode permettant d'obtenir le spectre d’absorption UV-visible de la forme chalcone de la glucoside-3 malvidine. Ce spectre presente des caracteristiques semblables a celles des spectres de chalcones de pigments flavylium, en general d’origine non naturelle. Toutefois, au maximum d’absorption (340-350 nm), la valeur du coefficient d’extinction moleculaire (≈ 10 000 M-1 .cm-1 ) reste faible devant celles des pigments precites (20 000 a 30 000 M-1 .cm-1 ).
Preliminary Phytochemical Content and Antidiabetic Potential Investigations of Panda oleosa (Pierre) Used in Kisangani Areas

Panda oleosa Pierre (POP), a tropical plant tree, has been used in traditional medicine in Kisangani city and around to treat various diseases including diabetes and HIV/AIDs. This study aims to evaluate the chemical composition of POP extracts while setting up chromatographic fingerprints for their quality control, and the anti-hyperglycemic potential of trunk bark aqueous extracts of POP. Common chemical reactions were used for identification of main secondary metabolic groups. Thin layer chromatography was used to set up several chromatographic fingerprints of water and alcoholic extracts while evaluating chemical composition. Oral glucose tolerance test served to induce hyperglycemia in a rabbit model. The extracts were given as 25 mg/kg, 50 mg/kg, and 100 mg/kg body weight, 30 minutes before loading animals with glucose 4 g/kg. Blood samples were collected at various times: just before extracts (T-30), before (T0) and after glucose load (T30, T60, T120, and T180). Blood glucose levels were measured with One Touch Glucometer. The identification tests revealed the presence of saponins (3.58%), tannins (5%); alkaloids, quinones, flavonoids, and terpenes sterols could not be formerly detected by the reagents used. Interesting chromatographic spots were observed whose behaviors are of catechic tannin proanthocyanes. The extract significantly reduced glucose levels in dose dependent manner as compared to control and glibenclamide reference groups. The average of mean percentage of reduction in glucose level at T120 with the extract 100 mg/kg was close to that of glibenclamide 0.25 mg/kg (49% and 40.2%). These findings back the traditional use of the plant to treat diabetic patients and constitute a foundation for an extensive study to find a new antidiabetic phythomedicine.
Integrative Analysis of Histopathological Images and Genomic Data in Colon Adenocarcinoma

Background Colon adenocarcinoma (COAD) is one of the most common malignant tumors in the world. The histopathological features are crucial for the diagnosis, prognosis, and therapy of COAD. Methods We downloaded 719 whole-slide histopathological images from TCIA, and 459 corresponding HTSeq-counts mRNA expression and clinical data were obtained from TCGA. Histopathological image features were extracted by CellProfiler. Prognostic image features were selected by the least absolute shrinkage and selection operator (LASSO) and support vector machine (SVM) algorithms. The co-expression gene module correlated with prognostic image features was identified by weighted gene co-expression network analysis (WGCNA). Random forest was employed to construct an integrative prognostic model and calculate the histopathological-genomic prognosis factor (HGPF). Results There were five prognostic image features and one co-expression gene module involved in the model construction. The time-dependent receiver operating curve showed that the prognostic model had a significant prognostic value. Patients were divided into high-risk group and low-risk group based on the HGPF. Kaplan-Meier analysis indicated that the overall survival of the low-risk group was significantly better than the high-risk group. Conclusions These results suggested that the histopathological image features had a certain ability to predict the survival of COAD patients. The integrative prognostic model based on the histopathological images and genomic features could further improve the prognosis prediction in COAD, which may assist the clinical decision in the future.
The Fate of the App: Economic Implications of Updating under Reputation Resetting

Online reviews on digital platforms are essential in building reputation and mitigating information asymmetry between buyers and sellers. Existing reviews, however, become less informative for products whose attributes frequently change over time. To cope with this challenge, digital platforms have explored reputation update mechanisms that adequately reflect this change. One distinctive mechanism in the context of apps is where reputation, and thus the underlying review history (including volume and valence), is reset with the release of a new app update. Intuitively, apps with low prior reputation are expected to benefit from updating while apps with high prior reputation may suffer. At the same time, apps face the market pressure to get frequently updated. This setup makes the developer’s update decision a double-edged one with updating turning into a strategic reputation management instrument. Additionally, and while the updating decision is typically up to the developer, this decision can also be driven by the hosting platform updating its own technology infrastructure. Exploiting an instrumental variable approach on an App Store panel dataset, we study app demand under reputation resetting driven either by the platform or the developer. We find that when reputation resetting is platform-driven, apps with low prior reputation enjoy a sharp increase in demand while those with high prior reputation experience a sharp decline in demand. We also find a positive association between developer-driven updates and app performance for both high- and low-reputation apps. These results inform platforms and developers about the tension between operational stability and loss of reputation.
“THE ‘REAL COST’ OF CAMPAIGNS: ENDS CAMPAIGN EFFECTIVENESS IN TERMS OF AWARENESS AND CONTENT”

Over the past few years, the use of electronic cigarettes and other vaping related products has spiked. This has quickly become an epidemic amongst the younger generations. These people did not smoke cigarettes before but are now addicted to nicotine. In an attempt to fight off the companies that are marketing these devices to teens and young adults, various anti-vaping campaigns have been launched. Two of the most notable and prevalent campaigns are the FDA’s “The Real Cost” and the Truth Initiative’s “Truth”. Using previously tested methods, this study compares and attempts to account for the short-term effectiveness, or lack thereof, of these two campaigns. Campaign awareness, motivation and message content are the key measures used in this study. The content is analyzed using the Elaboration Likelihood Model to measure the identification of central and peripheral cues. Three graduate students ran a content analysis on videos produced by these organizations and 138 students were surveyed regarding their awareness of the campaigns, vaping interest/motivation, and their perceptions of a video advertisement. Students were more likely to identify the central cues, but the peripheral predictors were the only ones found to be significant. Motivation is also a significant predictor of PSA effectiveness. It is recommended that the campaigns use better audience targeting and segmentation to identify individuals with a high motivation, or interest in vaping. Emotional Appeal is the most significant predictor of video effectiveness.
Comparative Analysis of Bacterial and Archaeal Population Structure by Illumina Sequencing of 16S rRNA Genes in Three Municipal Anaerobic Sludge Digesters

Understanding the microbial communities in anaerobic digesters is important for better regulation, operation, and sustainable management of the sludge produced at various stages of wastewater treatment processes. Microbial communities in the anaerobic digester of the gulf region where the climatic conditions and other factors may impact the incoming feed have not been documented. Archaeal and Bacterial communities of three full-scale anaerobic digesters, namely AD1, AD3 and AD5 were analyzed by Illumina sequencing of 16S rRNA genes. Among bacteria, the most abundant genus was fermentative bacteria Acetobacteroides (Blvii28). Other predominant bacterial genera in the digesters included thermophilic bacteria (Fervidobacterium and Coprothermobacter) and halophilic bacteria like Haloterrigena and Sediminibacter. This can be correlated with the climatic condition in Dubai, where the bacteria in the original feed may be thermophilic or halophilic as much of the water used in the country is desalinated seawater. Propionic acid-producing bacteria like Paludibacter and propionate oxidizing bacteria like W5 were also dominating group and were found in all the digesters. The predominant Archaea include mainly the members of phylum Euryarchaeota and Crenarchaeota belonging to genus Methanocorpusculum, Metallosphaera, Methanocella, and Methanococcus. The highest population of Methanocorpusculum (more than 50% of total Archaea) hydrogenotrophic archaea matches with the high population of Acetobacteroides (Blvii28) and Fervidobacterium bacteria which ferments the organic substrates to acetate and H2. Coprothermobacter, which is known to improve protein degradation by establishing a syntrophy with hydrogenotrophic archaea, was also one of the dominant genera in the digesters. This study, for the first time, contributes to an in-depth understanding of the phylogenetic diversity of a microbial community of three full-scale anaerobic digesters of a municipal wastewater treatment plant in Dubai, UAE.
Study of the photobleaching mechanisms of the 5,10,15,20-tetrakis(m-hydroxyphenyl) bacteriochlorin (m-THPBC), in solution, in vitro and in vivo.

Photodynamic therapy (PDT) has been developed as a treatment modality for a number of malignant and non-malignant disorders. PDT treatment is based on the presence of a drug with photosensitising and tumour localizing properties combined with visible light and oxygen. Accurate dosimetry is necessary to ensure complete treatment and to allow for consistent and reproducible patient outcomes. One of the key element which needs to be considered in dosimetry is photobleaching since it decrease the photosensitiser concentration during the treatment. It seems therefore important to understand the photobleaching mechanisms to adapt the photodynamic dose and receive the optimal treatment. The photobleaching quantum yield in solution supplemented with proteins is 5.7 x 10-4, the aggregated forms of the photosensitiser bleach slower than the monomerised forms. Under light exposure the m-THPBC is transformed in m-THPC, the phototransformation yield is influenced by the aggregation state of the molecule. Some other photoproducts such as dihydroxy m-THPBC, di-hydroxy m-THPC, dipyrin derivatives were observed. Singlet oxygen was found to be responsible of the photobleaching of both m-THPBC and m-THPC. In vitro, the m-THPBC LD50 is 0.7 J cm-2, and the photobleaching 3 to 5 times faster than m-THPC. Fluorescence microscopy study exhibits a discrepancy in the photosensitisers localisation, m-THPC is localised is the endoplasmic reticulum and m-THPBC accumulates in mitochondria. In vivo m-THPBC photobleaching is 4 to 10 times faster than m-THPC, with a good tumour accumulation. Taking as a whole these observations are particularly attractive in terms of therapeutic ratio and selectivity of the treatment and skin photosensitivity.
Characterization of the decolorizing activity of Azo Dyes by bacillus subtilis azoreductase AzoR1

The product of the Bacillus subtilis gene azoR1 is annotated as a putative azoreductase, production of which is induced in response to thiol-reactive compounds. Here we report on the decolorization of four azo dyes by azoreductase activity. The ability of overexpressed AzoR1 strain ORB7106 to catalyze decolorization of azo dyes was investigated on agar plates and in liquid cultures. The decolorization efficacy of a mutant, ORB7106, which has lost negative control of azoR1 expression, was significantly better than the parental strain (JH642), providing evidence that the azoR1 gene product is an azoreductase with the ability to decolorize azo dyes. ORB7106 showed 40-98% azo dye decolorization within 48 h. The bacterium exhibited a remarkable color removal capability over a wide range of Methyl Red concentrations (10-200 mg l), pH (5-9) and temperatures (25-45°C). A significant increase in the decolorization activity was observed after induction of AzoR1 production. The results suggested that AzoR1 production could be induced by Methyl Red. The decolorizing activity is primarily associated with the cytosolic fraction and requires NADH as a cofactor.
Antimicrobial Sensitivity pattern of Bacteria Causing Urinary Tract Infection among Diabetic Patients

Urinary tract infection is the presence and active multiplication of microorganism within the urinary tract. UTIs are group of infections that affects any part of urinary tract. The cross sectional descriptive study was conducted to determine the antibiotic sensitivity pattern of bacteria causing urinary tract infection in diabetic and non-diabetic patient from February 2016 to March 2016. Among the total 601 urine sample, 250 were diabetics and 351 were non diabetics. All samples were investigated by standard laboratory procedures. Out of diabetic patient 111(44.4%) were female and 139(55.6%) were male and among non-diabetic, 234(66.7%) were female and 117(33.3%) were male. The UTI prevalence rate was found to be 78 (13%) was statistically significant (p = 0.02), among the significant growth 6.8% diabetic and 6.2% non-diabetic. Escherichia coli (54) was the most predominant organism (42.5% in diabetic and 57.5% non-diabetic) followed by Staphylococcus aureus (8). Amikacin, Cotrimoxazole and Nitrofurantoin were most sensitive to E. coli isolated in diabetic and non-diabetic patients among the tested antimicrobials. High rate of resistance was observed with Norfloxacin and Nalidixic acid. Gentamicin, Cefotaxime, Cotrimoxazole and Ciprofloxacin were highly sensitive to S. aureus in diabetic patients while Oxacillin and Azithromycin were resistance and in non-diabetic patient highly sensitive antimicrobials were Azithromycin, Gentamicin, Cefotaxime, Cotrimoxazole, Vancomycin and Ofloxacin while Oxacillin was resistance. The antimicrobial susceptibility testing of bacterial isolates should be performed before the treatment of UTI. Key words : Diabetic, Urinary tract infection, Antimicrobial sensitivity.
Characteristics comparison between air-cored and iron-cored 100 kW HTS field winding synchronous motors

This paper presents comparative research on characteristics of air-cored and iron-cored high-temperature superconductor (HTS) field winding synchronous motors. The 100 kW air-cored model is designed analytically by Spatial Harmonic Method, and based on this model, the iron-cored model having the same output power is designed for comparison. Due to the substantial difference of permeability property between air and iron-core, there is a difference of magnetic field magnitude and angle with respect to the HTS tape c-axis, resulting in a different critical current of the field winding considering the anisotropic property of HTS tape. For a detailed comparison between two models, the following key motor characteristics are calculated through the Finite Element Method (FEM) simulation: 1) critical current; 2) HTS wire length; and 3) torque characteristics. From the simulation results, it can be confirmed that the critical current value of the iron-cored model increases by 33 %. Also, in the case of the superconducting wire consumption, those of the iron-cored and air-cored models are 95.3 m and 815.6 m, respectively. So the wire usage can be reduced to about 88 % by using iron core. However, in terms of torque characteristics, the torque ripple of the iron-cored model is about twice as large as that of the air-cored model, which may be a disadvantage on vibration and acoustic noise.
Routine blood parameters can detect early influenza virus infection in children

Purpose We aimed to explore the value of Routine blood parameters, such as the lymphocyte (LYM) count, platelet (PLT) count, lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), LYM*PLT and mean platelet volume-to-platelet ratio (MPV/PLT), are widely used to predict the prognosis of infectious diseases, for predicting influenza virus infection in children. Methods We conducted a single-center, retrospective, observational study on fever with influenza-like symptom in pediatric outpatients in different age groups and evaluated the predictive value of various routine blood parameters within 48 hours of the onset of fever after influenza virus infection. Results The LYM count, PLT count, LMR and LYM*PLT were lower, and the NLR and MPV/PLT were higher in the infected children. The LYM count, LMR and LYM*PLT in the infected group were lower in the 1- to 6-year-old group, and the LMR and LYM*PLT in the infected group were lower in the > 6-year-old group. In the 1- to 6-year-old group, the cutoff value of the LMR for predicting influenza A virus infection was 3.75, the sensitivity was 81.87%, the specificity was 84.31%, and the AUC was 0.886; the cutoff value of the LMR for predicting influenza B virus infection was 3.71, the sensitivity was 73.58%, the specificity was 84.31%, and the AUC was 0.843. In the > 6-year-old group, the cutoff value of the LMR for predicting influenza A virus infection was 3.05, the sensitivity was 89.27%, the specificity was 89.61%, and the AUC was 0.949; the cutoff value of the LMR for predicting influenza B virus infection was 2.88, the sensitivity was 83.19%, the specificity was 92.21%, and the AUC was 0.924. Conclusions Routine blood tests are simple, inexpensive and easy to perform, and they are useful for predicting influenza virus infection in children. The LMR had the strongest predictive value for influenza virus infection in children older than 1 year, especially influenza A virus infection.
New kinetic and mechanistic aspects of photosensitization of iodonium salts in photopolymerization of acrylates

1,3-Bis(p-bromophenylamino)squaraine which functions as an electron-transfer photosensitizer for a wide range of diphenyliodonium salts radical photoinitiators of triacrylate polymerization under UV-blue light irradiation is presented. The functionality of the photosensitizer is determined by the presence of a suitable co-initiator. For this purpose, several different diphenyliodonium salts were used as a source of active species for radical polymerization. The reactivity of the new iodonium salts was studied with ultraviolet-blue light initiated radical polymerization by photo-DSC using squaraine dye as a sensitizer. The iodonium salts functionated as radical initiators bearing different substitution patterns. Electron transfer from the excited state of the sensitizer to the iodonium salt results in initiating radicals. The ability to initiate free radical polymerization of TMPTA by iodonium salts studied is similar. Most of the iodonium salts exhibit no large differences regarding the reactivity in initiation of TMPTA polymerization. However, an introduction of a nitro group in the para position of the phenyl ring of the co-initiator results in a significant increase in the rate of polymerization and degree of monomer conversion. The dye-sensitized photoreaction mechanism of the SQ/I system was also confirmed.
