1- The Exponentiated Power Generalized Weibull: Properties and Applications
Authors: Fernando A. Peña-Ramírez, Renata R. Guerra, Gauss M. Cordeiro and Pedro R.D. Marinho

The exponentiated power Generalized Weibull distribution (EPGW) is a new lifetime model obtained from the exponentiated family for the power generalized Weibull (PGW) distribution. It can also be derived from a power transform on the exponentiated Nadarajah-Haghighi distribution. Since several structural properties of PGW distribution have not been studied, they can be obtained from those of the EPGW distribution. We also give a physical motivation for introducing the EPGW if the power parameter is an integer. Some of its mathematical properties are investigated. The maximum likelihood estimators, a simulation study and two applications to real data are also provided.

2- The Lindley Weibull Distribution: properties and applications
Authors: Gauss M. Cordeiro, Ahmed Z. Afify, Haitham M. Yousof, Selen Cakmakyapan and Gamze Ozel

We introduce a new three-parameter lifetime model called the Lindley Weibull distribution, which accommodates unimodal and bathtub, and a broad variety of monotone failure rates. We provide a comprehensive account of some of its mathematical properties. The new density function can be expressed as a linear combination of exponentiated Weibull densities. The maximum likelihood method is used to estimate the model parameters. We present simulation results to assess the performance of the maximum likelihood estimation. We prove
empirically the importance and exibility of the new distribution in modeling two data sets.

3- The phase portrait of the Hamiltonian system associated to a Pinchuk map
Authors: Joan Carles Artés, Francisco Braun and Jaume LLibre

In 1994, Pinchuk presented a class of counterexamples to the real Jacobian conjecture, that polynomial maps with positive Jacobian determinant in the plane must be injective. Since then, an open problem is to understand what really fails in this conjecture or how different are the Pinchuk from the injective maps.  In Mathematics, another point of view of a problem sometimes makes the solution more tangible. Due to Sabatini, we can study the injectivity of a map from the dynamic of a suitable vector field associated to it. Here we qualitatively describe the vector field associated to a Pinchuk map.

4- A weighted negative binomial Lindley distribution with  applications to dispersed data
Author: Hassan S. Bakouch

The proposed paper introduces a new discrete statistical distribution for modeling many types of over- and under-dispersed count data. Various properties of the distribution are obtained, involving generating functions, moments, random number generation, estimation, characterization, self-decomposability and infinite divisibility. Different count data sets are modeled by the distribution. Therefore, we hope that this model will be able to attract wider applicability in the analysis of count data.

5- Objective and subjective prior distributions for the Gompertz distribution
Authors: Fernando A. Moala and Sanku Dey

Gompertz distribution was introduced in connection with human mortality and actuarial sciences by Benzamin Gompertz (1825). This distribution is applied in various fields especially in reliability and life testing studies, actuarial science, epidemiological and biomedical studies.  In this paper, we present a statistical analysis (called Bayesian analysis) when there is a limited prior knowledge about the parameter of interest.  Our main interest in the Bayesian analysis is to select a prior distribution in which the information regarding the parameters is not considered substantial as compared with information from the data. A real data set has been analyzed for illustrative purposes.

6- A new characterization of the Euclidean sphere
Authors: Abdênago A. Barros, Cícero P. Aquino and José N.V. Gomes

There are important applications of the Lie derivative in the study of how geometric objects such as Riemannian metrics, volume forms, conformal vector fields, and symplectic forms behave under flows. In this paper, we obtain a new characterization of the Euclidean sphere as a compact Riemannian manifold with constant scalar curvature carrying a nontrivial conformal vector field which is also conformal Ricci vector field.

8- Silver and gold nanoparticles from tannic acid: synthesis, characterization and evaluation of antileishmanial and cytotoxic activities
Authors: Lourdes C.S. Lopes, Lucas M. Brito, Thayllan T. Bezerra, Kleyton N. Gomes, Fernando A. de A. Carvalho, Mariana Helena Chaves and Welter Cantanhêde

In this work, we have evaluated the antileishmania activity of Au and Ag nanoparticles stabilized with tannic acid, a tannin with vast biological application. The nanomaterials were analyzed by UV-Vis spectroscopy, zeta potential and TEM. Nanosilver inhibited the proliferation of Leishmania amazonensis promastigotes by adhering to the cell membrane, thus, causing alterations in the osmosis process. Tannic acid attenuates the cytotoxicity of nanosilver, while AuNPs did not present any antileishmania activity.

11- Environmental diagnosis of metals in streams near sugarcane cultivation areas: current and historical analysis in the central region of the State of São Paulo
Authors: Juliano J. Corbi, Camila G. Costa, Guilherme R. Gorni, Vanessa Colombo and Leonardo Rios

Streams located in areas of sugarcane cultivation receive elevated concentrations of metal ions from fertilizers applied in the soils of adjacent areas. Several studies conducted in the last 10 years have shown the contamination of sediments of streams in sugarcane cultivation areas, as well as the bioaccumulation of metals in the aquatic insects fauna. The present status confirms the previous results and still points to an increment of Cd in the sediment of agricultural streams. We strongly recommend the construction of a standard containing guiding values for aquatic sediment.

13- Biochemical characterization of the nuclease StoNurA from the hyperthermophilic archaeon Sulfolobus tokodaii
Authors: Tao Wei, Kunpeng Yang, Jie Zang and Duobin Mao

In this paper, we have described the biochemical characterization of the DNA nuclease StoNurA from S. tokodaii. Biochemical analysis demonstrated that StoNurA has DNA binding and Mn2+-dependent 5’–3’ exonuclease activities. The optimal conditions for the activity of this enzyme were 65 °C and pH 7.5. StoNurA was found to exist as a dimer in solution. Furthermore, the results of a pull-down analysis revealed that StoNurA formed a physical interaction with StoHerA. These results show that StoNurA exhibits 5’–3’ nucleolytic degradation activity, and could therefore play a critical role during archaeal recombinational repair.

15- Solaropsis brasiliana: anatomy, range extension and its phylogenetic position within Pleurodontidae (Mollusca, Gastropoda, Stylommatophora)
Authors: María Gabriela Cuezzo, Augusto P. de Lima and Sonia B. dos Santos

This work focuses on Solaropsis brasiliana, a key species of the South American malacofauna. We studied its anatomy proposing new characters and revising traditional ones. This information was included in a matrix with other known species of the genus upon which a cladistic analysis was carried out. The monophyly of the genus was tested and S. brasiliana sister relationships was proposed. We inquired into the known distribution of the genus Solaropsis in South America and proposed that the distribution area of S. brasiliana is restricted to Brazil, in the states of Rio de Janeiro, Espírito Santo, Bahia and Minas Gerais.

17- New data on the Late Cretaceous lizard Dicothodon bajaensis (Squamata, Borioteiioidea) from Baja California, Mexico reveals an unusual tooth replacement pattern in squamates
Authors: María Luisa Chavarría-Arellano, Tiago R. Simões and Marisol Montellano-Ballesteros

New specimens of the fossil lizard Dicothodon bajaensis (Cretaceous, North America) reveal a unique pattern of tooth replacement that was previously unknown among extant or fossil squamates. Most squamates replace their teeth throughout their entire life, and some specialized families stop replacing their teeth very early in their development. Specimens comprising an ontogenetic series of D. bajaensis indicate it had active tooth replacement during most of its life, but replacement ceased in adults. Other fossil lizards closely related to D. bajaensis had active and arrested tooth replacement, indicating D. bajaensis is possibly an evolutionary intermediary between both conditions.

18- Wollastonite to hinder growth of Aspergillus niger fungus on cotton textile
Authors:  Hamid R. Taguiyari, Reza Majidinajafabadi and Reza Vahidzadeh

Aspergillus niger is a constant threat to works of art in museums around the world. However, usual fungicides are not recommended to be used for preservation of works of art as to their toxicity to humans. The present project utilized nano-wollastonite to hinder growth of A. niger on cotton textiles. The results demonstrated negative effects of the fungus on mechanical strength of cotton textile was significantly limited by wollastonite. Therefore, it was concluded that NW positively protect cotton textile against A. nigra; however, complementary studies should be committed to make decision on the ultimate NW-content.

20- Molecular characterization of Moenkhausia (Pisces: Characiformes) populations with different lateral line developmental levels
Authors: Thaís F.M. Mota, Thomaz M.C. Fabrin, Gabriel C. Deprá, Luciano S. Gasques, Alessandra V. de Oliveira, Carla S. Pavanelli, Sônia M.A.P. Prioli and Alberto J. Prioli

The main distinguishing characteristics between the species M. bonita and H. marginatus are the presence of complete and incomplete lateral lines, respectively. However, specimens with the diagnostic features of M. bonita, collected from the floodplain of the upper Paraná River, exhibited different developmental levels of the lateral line, making it difficult the correct identification. We employ molecular tools to analyze the genetic similarities between M. bonita with different developmental levels of the lateral line and H. marginatus. The developmental level of the lateral line is not a consistent characteristic that distinguishes between Moenkhausia and Hemigrammus species.

22- First record of the invasive tapeworm, Schyzocotyle acheilognathi (Pseudophyllidea; Bothriocephalidae) in native freshwater fish, Brazil
Authors: Geovane A. de Souza, Victor O.  Moresca, Gustavo M. Teixeira, Fernando C.  Jerep and Aline Aguiar

Schyzocotyle acheilognathiare a tapeworm cestode commonly found in native freshwater fishes from Asia. This cestode parasites more than 200 cultured and wild fish species, besides several tetrapods including humans. In South America, Schyzocotyle were reported in Cyprinus carpio from a Brazilian fish farm, northern Paraná State and from the natural environment in C. carpio from Neuquen River, Argentina. However, there is no report of this parasite in South American native fishes. Herein, we present the first occurrence of the invasive tapeworm S. acheilognathi in Rineloricaria pentamaculata (Siluriformes, Loricariidae), a native freshwater catfish from the southern of Brazil.

23- The identity of the mysterious “Azara´s Parakeet” Sittace flaviventris Wagler, 1832
Author: Paul Smith

Wagler described Sittace flaviventris based on a written description by the Spanish naturalist Félix de Azara the No.276 “Maracaná cabeza y encuentro roxos”. However the identity of the bird has remained a mystery ever since. Based on a tail-less domestic individual, most authors have considered it an aberrant Aratinga parakeet, and it is currently considered a doubtful taxon.  Following a careful review, the identity of “Azara’s Parakeet” is confirmed as Red-spectacled Amazon Amazona pretrei (Temminck, 1830), a species that still occurs today in the region from where Azara described it. Sittace flaviventris is thus a junior synonym of Amazona pretrei.

26- Mutations in the melanocortin-1 receptor (MC1R) gene have no influence on the distinct patterns of melanic plumage found in the manakins of the genus Antilophia (Aves: Pipridae)
Authors: Leilton W. Luna, Weber A. Girão e Silva, Juliana Araripe, Isadora T.F. Pereira, Fernando M. D´Horta, Iracilda Sampaio, Horacio Schneider and Péricles S. do Rêgo

The MC1R gene is a widely-used marker for the investigation of the genetic determination of melanic plumage patterns. The genus Antilophia (Pipridae) includes only two species, where A. galeata has a black plumage, while A. bokermanni is predominantly white. This study investigates the possible association between mutations of the MC1R and the variation in plumage coloration observed in the two species. Concluding that the complete absence of any systematic association between the MC1R's variants and plumage coloration in the Antilophia species suggest that alternative mechanisms regulate the expression of the coloration of the plumage in these species.

27-Hypoglycemic property of triterpenoid saponin PFS isolated from Polyscias fruticosa leaves
Authors: Nguyen Thi Luyen, Nguyen Hai Dang, Phung Thi Xuan Binh, Nguyen Thi Hai and Nguyen Tien Dat

Postprandial hyperglycemia is an important target in type 2 diabetes treatment. Polyscias fruticosa has been used in Vietnam for food and medicinal purposes. The saponin 3-O-[β-d-glucopyranosyl-(1→4)-β-d-glucuronopyranosyl] oleanolic acid 28-O-β-d-glucopyranosyl ester (PFS) was isolated as a main compound from the leaves of Polyscias fruticosa. PFS strongly inhibited the digestive enzymes α-amylase and α-glucosidase.  PFS at 100 mg/kg body weight significantly decreased the postprandial blood glucose level in mice fed a high-sucrose diet. These results suggest that the saponin PFS can be used to prevent and treat diabetes and its complications.

32- Light environment influences the flood tolerance in Cordia americana (L.) Gottschling & J.S.Mill.
Authors: Caroline G. Samojeden, Ághata C. Artusi, Heliur A.A. Delevatti, Silvia V. Milesi, Rogério L. Cansian, Camila Kissmann and Tanise L. Sausen

The objective of this work was to evaluate the responses of Cordia americana to different light intensities combined with soil flooding. Seedlings were acclimated to two light treatments. Sun and shade plants were subjected to soil flooding during periods of 10 (short) and 30 (longer) days. Periods of short flooding, characterized in subtropical forests as from 5 to 15 days, favor the growth of shade plants and the roots sugar accumulation, fact that can explain the species distribution. However, long periods of flooding may be associated with light environment plasticity and associated with the ability to maintain the sugar content.

34- A new species of Microtetrameres (Nematoda, Tetrameridae) parasitizing Buteogallus urubitinga (Aves, Accipitridae) from northeastern Argentina
Authors: Mariano Dueñas Díaz, Fabiana B. Drago and Verónica Núñez

A new nematode species, Microtetrameres urubitinga n. sp. (Tetrameridae), is described parasitizing the great black-hawk, Buteogallus urubitinga (Accipitridae), from Argentina. Females of Microtetrameres spp. are spirally coiled and embedded in the gastric glands, with the tails directed towards the lumen of proventriculus, where filiform males move about freely. Females of M. urubitinga have a tail with a cuticular fold and males have spicules unequal and dissimilar, asymmetric caudal papillae and cloacal lips highly protruded. The low prevalence found of M. urubitinga (17%) would indicate the occasional ingestion of insects (intermediate hosts of Microtetrameres), since B. urubitinga mainly preys on vertebrates.

Authors: Priscila S. do Nascimento and Cristiana S. Serejo

The present study describes four new species of amphipods of the family Phoxocephalopsidae for Brazilian coast. This crustaceans with fossorial habit are common in the sediment of marine environments. Phoxocephalopsids are endemic to the Southern Hemisphere, but previous records to the Brazilian coast are limited to Phoxocephalopsis zimmeri Schellenberg, 1931.Phoxocephalopsis ruffoi sp. nov. had been misidentified as P. zimmeri since its first discover by Ruffo in 1956. The genus Puelche, previously monotypic, has now other three new species: Puelche irenae sp. nov.; Puelche longidactylus sp. nov.; Puelche mourae sp. nov. A key to Phoxocephalopsidae species from Brazil is provided.

41- Physicochemical quality profiles of commercial oral tablets and capsules containing lutein – impact of insufficient specific sanitary regulations
Authors: Carina de S. Anselmo, Thamara C. Mendes, Lucio M. Cabral and Valéria P. de Sousa

In Brazil, dietary supplements are registered as food and in the US do not require registration. In the present study, quality control tests, which are necessary to ensure formulation effectiveness, were carried out on tablet and capsules containing lutein, a carotenoid with antioxidant activity. It was selected formulations currently being marketed in the Brazilian and American markets. None of the formulations studied were found to be of satisfactory quality. Some formulations had no-significant available lutein content and the capsules had alarmingly negative dissolution results. The low physicochemical performance in these formulations can be explained by the lack of specific regulations.

42- New technique of intragastric sleeve: viability and survival in a pig model
Authors: Mariana S. Ribeiro, Ricardo P.A.S. Zorrón, Saulo José Q. Silva,  Silvia M.R. Cadena,   Fernanda Antunes, Marcelo B. dos Santos Junior, Luciana M. Mello, Haroldo José S. Igreja Júnior, Vilson L.  Batista, Jussara P. Scheffer and André L.A. Oliveira

The relevance was the use of intragastric sutures by single port access to reduce de stomach volume and food intake. This new technique is a variant of gastric sleeve that aims to minimize cost, increase public access, be less invasive and practical. The study consists to test the intragastric single port sleeve by endoplication in pigs, as this experimental model has a similar gastric system when compare to humans. Such assessments have not yet been reported in vivo. The results could demonstrate a safe technique, with acceptable technical  and reproducible viability, with short procedure time, without intra and postoperative complications.

43- Glucocorticoid susceptibility and in vivo ABCB1 activity differ in murine B cell subsets
Authors: Kelli M. da Costa, Raphael C. Valente, Joyle M.C. da Silva, Luciana S. de Paiva and Vivian M. Rumjanek

Hydrocortisone is well known for its immunosuppressive effects, however little is known about its effects on B cell differentiation. ABCB1 is a transporter that modulates the gradient of various hormones, including hydrocortisone/cortisol. Three daily injections of hydrocortisone reduced the number of most B cell subpopulations, being their differentiation inversely related to susceptibility to hydrocortisone. In general, B cell subpopulations exhibited in vivo ABCB1 activity. However, hydrocortisone treatment did not affect ABCB1 activity in most subpopulations analyzed. ABCB1 is finely regulated during the B cell differentiation although its efflux activity is not related to resistance to this glucocorticoid.

44- L-carnitine supplementation in the recovery of plasma L-carnitine in patients with heart failure submitted to coronary artery bypass grafting
Authors: Wanise M. Souza Cruz, Sheila M.S. Guimarães, Gabrielle C. Maciel,  Ana Beatriz A. Huguenin,  Monicque E.M. de Carvalho, Bárbara O. Costa, Geisiane A.  da Silva, Alexandre S. Colafranceschi, Fernanda B. Scalco and Marcia Ribeiro

The heart depends on the great production of energy through the oxidation of the fatty acid, to maintain adequate electrical and mechanical activities. L-carnitine is important in the oxidation of fatty acids in mitochondria. Reduction of plasma L-carnitine may compromise cardiac bioenergetics and is associated with decompensation and progression of heart failure. Myocardial revascularization surgery promotes oxidative stress, reduces plasma L-carnitine and this may compromise the heart's energy efficiency. A recommended daily dose for L-carnitine is still under study. We have shown that the supplementation of L-carnitine at the daily dose of 50mg / kg recovered the pre-operative plasma L-carnitine.

Authors: Lucieli K. F. Müller, Diovani Paiano, Nathieli B. Bottari, Janio M. Santurio, Aline Zampar, Maria R.C. Schetinger, Régis A. Zanette, Ricardo E. Mendes, Eduardo M. Gloria, Matheus D. Baldissera and Aleksandro S. da Silva

Mycotoxins are toxic compounds produced by filamentous fungi that challenge pigs in the most diverse production cycle stages. Mycotoxins induced oxidative stress in piglets. The effect of spray-dried porcine plasma (SDPP) on mycotoxin contamination diet was tested. SDPP minimized the mycotoxin-induced oxidative stress, and improved protein levels use by the piglets. SDPP had beneficial effects for the production system and health of the litters, protecting against the negative effects of the mycotoxin present in the diet.

47- Cohort study of cardiovascular risk in asymptomatic young adults: subclinical atherosclerosis and coronary calcium score
Authors: Sadi Poletto, Paulo R. Schvartzman, Neide M.  Bruscato and Emilio Moriguchi

Detectable coronary artery calcification (CAC) is an important marker of subclinical atherosclerosis. A cohort of 155 asymptomatic young adults < 45 years, followed-up from 1999-2016, was assessed with a coronary calcium score in 2016. Over 17 years, there was only one case of nonzero CAC score in a man. His 75th percentile for age and sex indicated an aggravating factor for coronary artery disease and high risk of clinical events in 2-5 years. An important finding was the reduction in HDL-C levels, with participants who gained 1 cm in waist circumference showing a mean reduction of 0.36 mg/dL in HDL-C.

48- Dextran Sulphate of Sodium-induced colitis in mice: antihyperalgesic effects of ethanolic extract of Citrus reticulata and potential damage to the central nervous system
Authors: Alexandre S. Hilel, Bruna Gysemans, Maria E.M. Lisbôa, Ana C. Heymanns, Viviane Freiberger, Letícia Ventura, Rachel F. Magnago, Clarissa M. Comim, Verônica Horewics, Daniel F. Martins, Franciane Bobinski and Anna P. Piovezan

Citrus genus is one of the most important crops worldwide and its peels are rich in compounds with antioxidant and analgesic properties. We evaluated the effects of ethanolic extract from peels of mature Citrus reticulata Blanco (EECR) on the mechanical hyperalgesia in DSS-induced colitis mice, as well as the oxidative damage in different brain regions caused by intestinal inflammation. EECR treatment reduced hyperalgesia in animals subjected to colitis, while lipid peroxidation or carbonyl proteins were augmented in these animals. These results indicated an antihyperalgesic effect for EECR and a potential impairment of the central nervous system functioning caused during colitis.

Authors: Geraldine Schlapp, Gabriel Fernández-Graña, Ana Paula Arévalo and  Martina Crispo

The aim of this work was to evaluate the results and the efficiency of an environmental microbiological monitoring program implemented at our SPF mouse facility, based in sedimentation and swabbing, after seven years. The median for bacteria and fungi in sampled areas was ≤2CFU/2h for settle plates and <1CFU/swabbing plate, satisfying the requirements for grade C of EU-GMP, with some modifications. Our program was useful to define a safe range of microbiological counts. Mice SPF status was maintained throughout this study, confirmed by our Health Monitoring program. This work could encourage mouse facilities staff to implement this kind of program.

53- Study of barium sulfate dissolution by scale dissolver based on solutions of DTPA
Authors: Geizila A.P. Abib, Georgiana F. da Cruz and Alexandre S.L. Vaz Junior

In offshore oil wells, the perform seawater injection often leads to sulfate salts formation due to chemical incompatibility between formation water and sea water. The barium sulfate (BaSO4) is the most problematic mineral scale and may cause many complications. In order to solve this issue, polycarboxylic acids, such as diethylene triamine pentaacetic acid (DTPA), are used. Thus, the primary focus of this work was to develop an experimental procedure to study the BaSO4 dissolution, initially through static tests to understand the relationship between dissolver concentration, temperature and dissolution time, and then through dynamic tests in sandstone reservoirs.

Authors:  Juliano R.A. Pinto, Natalia B. Sanches, Milton F. Diniz, Régis S. Santos,  José I.S. de Oliveira and Rita de Cássia L. Dutra

On November 27, 2017, the Brazilian Supreme Court decided to prohibit the exploitation and commercialization of asbestos and the materials that contain it from all over the country, so that those who use it need an alternative. To adapt to the new determination, the Technological Institute of Aeronautics (ITA) and the Institute of Aeronautics and Space (IAE) conducted a research using a mixture of Expanded Perlite and Cork in Powder. After tests, this mixture shows satisfactory results that allow the replacement of asbestos in flexible thermal protections used in the combustion chambers of solid rocket engines.

55-The positive moderating effect of absorptive capacity on  R&D investment: the case of Argentina’s ict firms
Authors: Luis Felipe Agramunt and Juan M. Berbel-Pineda

This study has as referential framework on the successful international performance of the Argentinian TIC´s small firms. An empirical case which include almost 200 firms show how the efforts that these firms developed using outside knowledge, has improved their results in international markets. The absorptive capacity (ACAP) has an important role in that process. It includes all the internal resources that the firms has and that gave them the possibility to transform the external knowledge into a business opportunity (innovation). The external knowledge is particularly important for these firms because usually they don´t have the chance to create it by themselves.
