(Amer Chemical Soc, 2009-08-01) Maia Rigo, Tainara Rodrigues [UNESP]; Flumignan, Danilo Luiz [UNESP]; Boralle, Nivaldo [UNESP]; Oliveira, Jose Eduardo de [UNESP]; Universidade Estadual Paulista (Unesp)
In (his work, the combination of hydrogen nuclear magnetic resonance ((1)H NMR) fingerprinting of gasoline with pattern-recognition analyses provides an approach to distinguish Brazilian commercial gasoline, processed in different states of Brazil. Hierarchical cluster analyses (HCA) and principal component analyses (PCA) were carried out on chemical shifts in order to observe any natural grouping feature. while soft independent modeling of class analogy (SIMCA) was performed to classify external samples into previously origin-defined classes. PCA demonstrated that a small number of variables dominate the total data variability since the first three principal components (PCs) accounted for 64.9% of total variability; whereas a HCA dendrogram shows five natural cluster grouping features. Following optimized (1)H NMR-SIMCA algorithm, sensitivity values in the training set with leave-one-out cross-validation (86.0%) and external prediction set (77.3%) were obtained. Governmental laboratories could employ this method as a rapid screening analysis for origin authentication related to tax evasion purposes.

(Gordon Breach Publishing, Taylor & Francis Group, 2001-01-01) Santana, A. M.; Mauro, A. E.; Almeida, E. T. de; Netto, A. V. D.; Klein, S. I.; Santos, R. H. D.; Zoia, J. R.; Universidade Estadual Paulista (Unesp); Universidade Católica de Brasília (UCB); Universidade de São Paulo (USP)
The compound [Pd(bzan)(mu -N-3)](2) 1, bzan = benzylideneaniline, was prepared from [Pd(bzan) (mu -OOCCH3)](2) by an anion exchange reaction. The 1,3-dipolar cycloaddition of carbon disulfide to the bridged coordinated azide in the cyclometallated compound I was investigated. The species resulting from this reaction, di(mu -N,S-1,2,3,4-thiatriazol-5-thiolate)bis[(benzylideneaniline)palladium(II)] 2, was characterized by IR spectroscopy and X-ray diffraction. The compound 2 is a dimer containing two [Pd(benzylideneaniline)] moieties connected by two vicinal bridging N,S-1,2,3,4-thiatriazole-5-thiolate anions in a square-planar coordination geometry for the palladium atoms.

(Sociedade Brasileira de Química, 2014-06-01) Silva, Gervásio Paulo Da; Contiero, Jonas [UNESP]; Ávila Neto, Paulo Marcelo [UNESP]; Lima, Cristian Jacques Bolner De [UNESP]; Universidade do Estado da Bahia (UNEB); Universidade Estadual Paulista (Unesp)
1,3-propanediol is a high-value specialty chemical which has many industrial applications. Its main use is the production of the polymer polypropylene terephthalate, a thermoplastic used in the textile and automobile industries. The interest in 1,3-propanediol production from glycerol bio-conversion has increased after the employment of biodiesel by various countries, being produced by chemical synthesis from petroleum intermediates or biotechnologically by microbial fermentation. Glycerol is an abundant low-cost byproduct from biodiesel refineries, and it is the only substrate that can be naturally or enzymatically converted to 1,3-propanediol by microbial fermentation. In this review, information on 1,3-propanediol's importance, production and purification are presented, along with results from recent research on glycerol microbial conversion to 1,3-propanediol. The bio-production of this intermediate compound from glycerol is very attractive both economically and environmentally, since it allows the replacement of fossil fuels by renewable resources.

(2020-10-26) Costa, Joao Gustavo Leite [UNESP]; Rodrigues, Pedro Henrique Ferrarrezi [UNESP]; Paim, Leonardo Lataro [UNESP]; Sanches, Alex Otavio [UNESP]; Malmonge, Jose Antonio [UNESP]; Da Silva, Michael Jones [UNESP]; Universidade Estadual Paulista (Unesp)
In this study, we obtained and characterized a piezoelectric composite with 1-3 connectivity from castor oil polyurethane (PUR) and lead zirconate titanate (PZT) rods. Two samples were obtained, one with 15% PZT volume and the other with 34% PZT volume. The ac electrical properties of the 1-3 piezoelectric composite samples demonstrated the frequency-dependence behavior of disordered solids. The piezoelectric coefficient (d33) was greatly influenced by the number of PZT rods and the matrix curing process. The sample with 34% PZT volume showed a higher d33value, (246 pC/N measured after 30 d of polarization). The composites were evaluated for use in acoustic emission wave sensors for application in structural health monitoring.

(Wiley-Blackwell, 2009-10-01) Caracelli, Ignez [UNESP]; Zukerman-Schpector, Julio; Amaral, Monica F. Z. J.; Stefani, Helio A.; Tiekink, Edward R. T.; Universidade Estadual Paulista (Unesp); Universidade Federal de São Carlos (UFSCar); Universidade de São Paulo (USP)
The tetrahydropyrimidinone ring in the title compound, C(20)H(20)N(2)O(2), is in a half-boat conformation with the N-C-N C atom 0.580 (2) angstrom out of the plane defined by the remaining five atoms. In the crystal structure, molecules are connected into centrosymmetric dimers via N-H center dot center dot center dot O interactions. The dimeric aggregates are linked into supramolecular chains along the a axis via C-H center dot center dot center dot pi interactions.
(1-x)PMN-xPT ceramics prepared by conventional and modified columbite route: Effect on electrical properties
(Taylor & Francis Ltd, 2006-01-01) Cavalheiro, A. A.; Bruno, J. C.; Zaghete, M. A.; Varela, José Arana [UNESP]; Universidade Estadual Paulista (Unesp)
This study aims to demonstrate how the chemical homogeneity of B cations affects the microstructure and electrical responses of (1-x) PMN-xPT ceramics. Two methodologies were employed to synthesize three different compositions, with x assuming the values 0.10, 0.28, and 0.35. If compared to conventional method, the Ti-modified columbite route, which is characterized by higher B cation homogeneity, leads to PMN-PT powders and ceramics with lower content of PNT pyrochlore phase and, for 0.65PMN-0.35PT composition, minor amount of tetragonal phase is found. Conclusively, PMN-PT ceramics obtained by modified route favors B cations homogeneity, enhancing the dielectric, ferroelectric and piezoelectric properties.

(Royal Soc Chemistry, 2012-01-01) Manzani, Danilo [UNESP]; Ferrari, Jefferson Luis; Polachini, Ferminio Cesar [UNESP]; Messaddeq, Younes [UNESP]; Lima Ribeiro, Sidney Jose [UNESP]; Universidade Estadual Paulista (Unesp); Univ Laval
Glasses with base composition (in mol%) 70TeO(2)-15GeO(2)-5K(2)O-10Bi(2)O(3) were prepared by the melt-quenching method. Er3+/Yb3+-doped and non-doped glass compositions were used as core and cladding, respectively, in the preparation of optical fibers through the sucking method. Infrared emission at 1550 nm and up-conversion emission in the visible range under 980 nm pumping are reported for glasses and optical fibers. A relatively large (Delta lambda = 91 nm) bandwidth was observed for the Er3+ 1550 nm emission. Up-conversion luminescence was observed and evaluated as a function of pump power at 980 nm. The efficient emission in the visible and infrared ranges makes this optical fiber potentially useful for amplifier and laser applications in photonics.
1.5 mu m emission and infrared-to-visible frequency upconversion in Er+3/Yb+3-doped phosphoniobate glasses
(Elsevier B.V., 2006-09-15) Barbosa, A. J.; Dias Filho, F. A.; Messaddeq, Younes [UNESP]; Ribeiro, Sidney José Lima [UNESP]; Goncalves, R. R.; Luthi, S. R.; Gomes, A. S. L.; Universidade Estadual Paulista (Unesp); Universidade Federal de Pernambuco (UFPE)
Sodium phosphoniobate glasses with the composition (mol%) 75NaPO(3)-25Nb(2)O(5) and containing 2 mol% Yb3+ and x mol% Er3+ (0.01 <= x <= 2) were prepared using the conventional melting/casting process. Er3+ emission at 1.5 mu m and infrared-to-visible upconversion emission, upon excitation at 976 nm, are evaluated as a function of the Er3+ concentration. For the lowest Er3+ content, 1.5 mu m emission quantum efficiency was 90%. Increasing the Er3+ concentration up to 2 mol%, the emission quantum efficiency was observed to decrease to 37% due to concentration quenching. The green and red upconversion emission intensity ratio was studied as a function of Yb3+ co-doping and the Er3+-Er3+ energy transfer processes. (c) 2006 Elsevier B.V. All rights reserved.

A 10-year follow-up of different intra-radicular retainers in teeth restored with zirconia crowns
(2019-01-01) Calabro, Debora E.; Kojima, Alberto N. [UNESP]; Pecorari, Vanessa Gallego Arias; Saraceni, Cintia Helena Coury; Blatz, Markus B.; Özcan, Mutlu; Mesquita, Alfredo Mikail Melo; Paulista University (UNIP) São Paulo; Universidade Estadual Paulista (Unesp); Paulista University (UNIP); University of Zurich; University of Pennsylvania
Purpose: To evaluate the survival rate in restored teeth with three different types of retainers prior to the fixing of crowns with zirconia through this retrospective clinical study. It is unclear how the type of post and core rehabilitation, and type of resin cement affect the longevity of teethrestored with crowns. Methods: In a private clinic, a total of 101 retainers installed by the same professional between June 2008 and January 2018, with an average time of 58.2 months (4.8 years), were analyzed regarding the following factors: survival, cement and failure type. Three types of retainers were used according to the indications found in the literature: filling with Z250 light-cured composite resin, 22 elements; fiberglass post with Z250 light-cured composite resin, 45 elements; and cast metallic core in silver-tin alloy, 34 elements. The retainers were cemented with chemically cured cement, U100, U200, or Panavia F. Results: Data were subjected to Kaplan-Meier analysis (p=0.495). Although the study presented several limitations, no significant differences were observed in the success rates between the types of intra-radicular retainers and the type of cement. The success rates were as follows: metal core, 97.1%; fiberglass post, 95.6%; and filling, 100%. On average, failures occurred at 48.4 months. Conclusion: In view of the results, it is possible to conclude that the different retainers evaluated have similar survival rates.

(2022-01-01) Cuoghi, Isabela Campeti; da Silva Soares, Mariana Furlani; dos Santos, Gustavo Motta Cabello; Candido-dos-Reis, Francisco José; Poli-Neto, Omero Benedicto; de Andrade, Jurandyr Moreira; Bosquesi, Priscila Longhin [UNESP]; Orlandini, Leonardo Fleury; Tiezzi, Daniel Guimarães; União das Faculdades dos Grandes Lagos; Universidade de São Paulo (USP); Universidade Estadual Paulista (UNESP)
Background Mammographic screening has been used to reduce breast cancer mortality worldwide and remains the main modality for the early detection of this disease. Women from low and middle-income countries still lack access to periodic mammograms and efficient health care. This cross-sectional study aimed to explore opportunistic mammographic coverage in Brazil, while considering the privately insured population and its association with early breast cancer (EBC) detection. Methods Data on population, gross domestic product (GDP), number of mammograms performed under the Sistema Único de Saúde (SUS) public health system or private system, and women diagnosed with early-stage breast cancer from 2010 to 2019 were retrieved from publicly available databases. Results A total of 39 555 636 mammograms with an average of 3 955 564 ± 395 704 mammograms were obtained per year from 2010 to 2019 in Brazil. Most examinations (58.6%) were performed in the target population (50-69 years old), while 32% were performed in women aged 40-49, and 9.4% were performed in women <40 years or >70 years of age. The 10-year mammogram coverage was 30.6% in the target population and 24.8% in the population aged 40-49 years, with significant variation across states and municipalities. The overall EBC detection rates in Brazil were 30.6% in populations aged 50-70 and 24.8% in those aged 40-50 years. We observed a positive correlation between coverage and EBC detection rate (r = 0.68; P = 0.0001 (50-70 years) and r = 0.75; P < 0.0001 (40-50 years)). According to the GDP, the municipalities with higher GDP per capita had higher mammogram coverage (P < 0.0001). Conclusions The coverage of mammographic screening for women under the SUS is far below the international guidelines. Additionally, a significant number of mammograms have been performed in non-target populations. This scenario reflects the problematic screening programs in developing countries and reflects low rates of EBC diagnosis. As Brazil is a continental country with heterogeneous socioeconomic indicators, we observed significant variations in the number of mammograms performed by age groups when separated by states and municipalities. Even when considering supplemental health system coverage, municipalities with higher GDP per capita were associated with higher mammogram coverage.

A 100% waste-based alkali-activated material by using olive-stone biomass ash (OBA) and blast furnace slag (BFS)
(2017-09-15) Font, A.; Soriano, L.; Moraes, J. C.B. [UNESP]; Tashima, M. M. [UNESP]; Monzó, J.; Borrachero, M. V.; Payá, J.; Universitat Politècnica de Valencia; Universidade Estadual Paulista (Unesp)
This study presents the use of olive-stone biomass ash (OBA) as an alkali source in alkali-activated materials (AAM) based on blast furnace slag (BFS). The OBA was physically and chemically characterized. It presented high K2O and CaO contents, and yielded high alkalinity in water medium. The newly designed OBA + BFS mixes (a 100% waste-based AAM) reached a compressive strength of 30 MPa after 7 days of curing at 65 °C, which was higher than for BFS activated with KOH solution. Thermogravimetric studies showed the formation of C-S-H/(C,K)-A-S-H gels and hydrotalcite. The OBA presented excellent performance as a component in AAM and a good valorisation was achieved.
The 100th: An appealing new species of Dendropsophus (Amphibia: Anura: Hylidae) from northeastern Brazil
(Public Library Science, 2017-03-08) Dias, Iuri Ribeiro; Baptista Haddad, Celio Fernando [UNESP]; Suzart Argolo, Antonio Jorge; Dill Orrico, Victor Goyannes; Univ Estadual Santa Cruz; Universidade Estadual Paulista (Unesp)
We describe a new species of the Dendropsophus leucophyllatus Group from the Atlantic Forest of the southern region of State of Bahia, Brazil. It can be distinguished from all species of the D. leucophyllatus Group on the basis of morphological characters (especially its unique dorsal pattern and snout in dorsal view), advertisement calls and divergence in mitochondrial DNA gene sequences. The inclusion of D. anceps on the group remains controversial but our phylogenetic analyses do not recover the new species as sister to syntopic species of the D. leucophyllatus Group (with or without D. anceps). These results also highlight the palimpsest that is past relation between the Atlantic and Amazon forests.
[10]-Gingerol-Loaded Nanoemulsion and its Biological Effects on Triple-Negative Breast Cancer Cells
(Springer, 2021-05-18) Zanesco-Fontes, Ideli; Lopes Silva, Ana Carolina [UNESP]; Silva, Patricia Bento da [UNESP]; Duarte, Jonatas Lobato [UNESP]; Di Filippo, Leonardo Delello [UNESP]; Chorilli, Marlus [UNESP]; Cominetti, Marcia Regina; Baptista Moreno Martin, Ana Carolina; Universidade Federal de São Carlos (UFSCar); Universidade Estadual Paulista (Unesp)
The apoptotic, cytotoxic, and cytostatic activities for [10]-gingerol in triple-negative breast cancer cells (TNBCs) were already reported. However, despite these important antitumor activities, the compound has the disadvantage to have a hydrophobic characteristic, hindering in vivo administration. To surpass this issue, in this study we have created a [10]-gingerol-loaded nanoemulsion (10GNE) in order to increase the stability and solubility of the compound. The nanoemulsion was characterized and tested for its cytotoxic, cytostatic, and apoptotic effects on a panel of murine and human TNBC cell lines, as well as non-tumor cells, and compared with a [10]-gingerol-free nanoemulsion (NE) and with [10]-gingerol itself. Except for the murine 4T1.13 cell line, the IC50 of the free 10G molecule, after 72 h of incubation, was higher in all cell lines tested, both murine and human, demonstrating therefore the efficacy of the 10GNE regarding cytotoxicity. In murine tumor cells, 60 mu M 10GNE was able to arrest cell cycle at sub-G0 phase and induce apoptosis, leading to 48% and 78% of total cell death in 4T1.13 and 4T1Br4 murine tumor cells, respectively. This represents an improvement compared to 10G-free molecule that only induced 74% of total apoptosis at 100 mu M in 4T1Br4 cells. Taken together, our results show that nanoformulation preserved the [10]-gingerol cytotoxic and cytostatic properties and improved its apoptotic function on murine TNBC cell lines. These data open new perspectives to a more suitable drug-delivery approach for [10]-gingerol for TNBC treatment that should be further demonstrated using in vivo assays.
10Boron Is Mobile in Cowpea Plants
(2021-10-15) Silva, Sylvia Leticia Oliveira; Prado, Renato de Mello [UNESP]; Abreu-Junior, Cassio Hamilton; Silva, Gilmara Pereira da; Silva Júnior, Gabriel Barbosa da; Silva, José Lucas Farias da [UNESP]; Federal Institute of Maranhão; Universidade Estadual Paulista (UNESP); Universidade de São Paulo (USP); State University of Mato Grosso (UNEMAT); Federal University of Piauí
Cowpea [Vigna unguiculata (L.) Walp] is cultivated in tropical and subtropical regions worldwide, but its production is usually limited by boron (B) deficiency, which can be mitigated by applying B via foliar spraying. In plants with nutrient mobility, the residual effect of foliar fertilization increases, which might improve its efficiency. An experiment was carried out to evaluate the concentration and mobility of the B isotopic tracer (10B) in different organs of cowpea plants, after the application of this micronutrient in the growing media and also to leaves. Treatments were designed based on B fertilization as follows: without B in the growth media, with 10B applied via foliar spraying (10B-L), with B in the growth media (substrate) and 10B via foliar spraying (10B-L + B-S), and with 10B in the growth media (substrate) without foliar spraying (10B-S), and a control without fertilization. A redistribution of 10B was observed in new leaves when the element was supplied via foliar spraying, resulting in greater leaf area, dry mass and dry matter production of aerial parts, and also the whole plant. 10Boron was redistributed when applied via foliar spraying in cowpea plants, regardless of the plant's nutritional status, which in turn might increase internal B cycling.
11-Oxoaerothionin isolated from the marine sponge Aplysina fistularis shows anti-inflammatory activity in LPS-stimulated macrophages
(Informa Healthcare, 2012-12-01) Medeiros, Alexandra Ivo de [UNESP]; Gandolfi, Renata C.; Secatto, Adriana; Falcucci, Romulo M.; Faccioli, Lucia H.; Hajdu, Eduardo; Peixinho, Solange; Berlinck, Roberto G. S.; Universidade Estadual Paulista (Unesp); Universidade de São Paulo (USP); Universidade Federal do Rio de Janeiro (UFRJ); Universidade Federal da Bahia (UFBA)
Marine sponges of the order Verongida are a rich source of biologically active bromotyrosine-derived secondary metabolites. However, none of these compounds are known to display anti-inflammatory activity. In the present investigation, we report the anti-inflammatory effects of 11-oxoaerothionin isolated from the Verongida sponge Aplysina fistularis. When RAW264.7 cells and primary macrophages were preincubated with 11-oxoaerothionin and stimulated with LPS (lipopolysaccharide), a concentration-dependent inhibition of iNOS (inducible nitric oxide synthase) protein and NO2- (Nitrite) production were observed. The same effect was observed when proinflammatory cytokines and PGE(2) (Prostaglandin E2) production was evaluated. In summary, we demonstrated that in the presence of LPS, 11-oxoaerothionin suppresses NO2 and iNOS expression as well as inflammatory cytokines and PGE(2).
A 12 kW three-phase low THD rectifier with high-frequency isolation and regulated DC output
(Institute of Electrical and Electronics Engineers (IEEE), 2004-03-01) de Seixas, FJM; Barbi, I; Universidade Estadual Paulista (Unesp); Universidade Federal de Santa Catarina (UFSC)
A robust 12 kW rectifier with low THD in the line currents, based on an 18-pulse transformer arrangement with reduced kVA capacities followed by a high-frequency isolation stage is presented in this work. Three full-bridge (buck-based) converters are used to allow galvanic isolation and to balance the dc-link currents, without current sensing or current controller. The topology provides a regulated dc output with a very simple and well-known control strategy and natural three-phase power factor correction. The phase-shift PWM technique, with zero-voltage switching is used for the high-frequency dc-dc stage. Analytical results from Fourier analysis of winding currents and the vector diagram of winding voltages are presented. Experimental results from a 12 kW prototype are shown in the paper to verify the efficiency, robustness and simplicity of the command circuitry to the proposed concept.
