Research ArticleOpen accessIn the author namesOligoasthenoteratozoospermia and Necrozoospermia: A Study of Sperm Na+, K+-ATPase α4 and Plasma Membrane Ca2+-ATPase 4 RegulationSilvia W. Lestari, Dessy Noor Miati, AsmarinahThe oligoasthenoteratozoospermia (OAT) and necrozoospermia are the extreme sperm abnormalities in male infertility. These sperm abnormalities may be related to the imbalance of ion transport which mediated by the ion-transporting P-type ATPases, such as Na+, K+-ATPase and Ca2+-ATPase. Until now, there is limited data about the activity of Na+, K+-ATPase and Ca2+-ATPase in sperms in the OAT and necrozoospermia samples. … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 3 Aug 2018 · 11,273 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Didactic Laboratory of Theory and Design of Structures for Bachelor Civil Engineering Students in CagliariMariangela Deligia, Fabrizio Pittau, Silvia Corda et al.The course of Theory and Design of Structures for the Bachelor courses of Civil Engineering in Academic Year 2016-17 at the University of Cagliari was divided in two semesters: the first one dealing with theoretical aspects, in the second one a didactic laboratory was developed with the aim of a structural design of a building.

Research ArticleOpen accessIn the author namesImpact of an Extra Layer on the Stacking Algorithm for Classification ProblemsRodolfo Lorbieski, Silvia Modesto NassarClassifying and making decisions are tasks performed by any human being in their daily lives. Learning algorithms have been widely studied as tools to aid information management, with an objective to maximize the generalization capacity. Learning algorithms can be used individually or as a committee of machines (ensembles). An ensemble uses the solutions provided by several machines, making different combinations … …Journal of Computer Science, Vol. 14, Issue 5 · 10 Jan 2018 · 8,292 accessesView PDFCite
Review ArticleOpen accessIn the author namesDoes Intellectual Capital Affect the Volatility of Returns? An Empirical Investigation on Italian Listed CompaniesBrett W. Cantrell, Daniela Coluccia, Stefano Fontana, Silvia SolimeneIn modern information economies, economic success increasingly depends on the ability to apply knowledge and to transform it into firm value. While intellectual capital plays a critical role in firm success, it is an intangible asset that is difficult to measure and that is unrecorded by the firm. Difficulties in measuring intellectual capital, as well as the dynamic nature of … …American Journal of Applied Sciences, Vol. 14, Issue 12 · 10 Jan 2018 · 8,524 accessesView PDFCite
Research ArticleOpen accessIn the author namesMultidrug-Resistant Bacterial Pathogens Assessment in Canine Ophthalmic InfectionsRicardo Antonio Pilegi Sfaciotte, Lincoln Garcia Coronel, Alessandra Snak et al.The objective of this study was to identify the main microorganisms associated with ophthalmic infections and determine the resistance profile of these isolates against antimicrobial drugs. 26 bacterial isolates from 18 canine ophthalmic infections were submited to the phenotypic resistance profile for 36 drugs of 12 classes of antimicrobials, research of multidrug-resistant strains with importance in public health and detection … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 1 · 2 Jan 2018 · 7,280 accessesView PDFCite
Review ArticleOpen accessIn the author namesSpermatogonial Stem Cells: A Current Update in the Management of Azoospermic Infertile MenSilvia W Lestari, Debby AdityaOne of the management of azoospermia is utilizing Assisted Reproductive Technologies (ART) by Intra-Cytoplasmic Sperm Injection (ICSI) with sperm obtained from the epididymis or directly from testis. In some conditions such as hypogonadism or undescended testis, the sperm are not successfully obtained. Thus, it is considered to perform Spermatogonial Stem Cells (SSCs) culture to restore men fertility. The objective of … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 5 Dec 2017 · 6,924 accessesView PDFCite
Research ArticleOpen accessIn the author namesSperm DNA Fragmentation and Apoptosis Levels: A Comparison of the Swim up and the Density Gradient Centrifugation Methods for Sperm PreparationSilvia W. Lestari, Triyana Sari, Dwi A. PujiantoThis study investigated the efficiency of two sperm preparation methods, namely, density gradient centrifugation and the swim-up method, in selecting spermatozoa based on the DNA fragmentation index and the apoptosis levels. Fifteen semen samples from infertile couples underwent sperm preparation in this study. The Makler® counting chamber and Eosin Y staining were used to analyse the sperm concentration, motility and … …OnLine Journal of Biological Sciences, Vol. 16, Issue 4 · 14 Nov 2016 · 7,422 accessesView PDFCite
Research ArticleOpen accessIn the author namesFuzzy Modeling for Multi-Label Text Classification Supported by Classification AlgorithmsBeatriz Wilges, Gustavo Mateus, Silvia Nassar et al.The ever-increasing amount of information on the Web is organized in structured, semi-structured and unstructured data. Text classification systems, capable of handling such different structures, may facilitate the work of important tasks such as indexation and information retrieval in search engines. The objective of this research is to develop a method for the classification of documents into multiple categories with … …Journal of Computer Science, Vol. 12, Issue 7 · 22 Aug 2016 · 7,221 accessesView PDFCite
Research ArticleOpen accessIn the author namesDevelopment of a Short-Term Canine Full-Thickness Skin Organ Culture Method under Serum-Free ConditionsFrancesca Abramo, Andrea Pirone, Carla Lenzi et al.Full-thickness canine skin organ culture models could provide an entirely new opportunity for studying wound healing, keratinization disorders and allergic skin diseases, all of which have high prevalence and severe impact on canine quality of life. Here we present a canine organ culture method for the short-term maintenance of full-thickness, adult, canine skin in serum-free medium and investigate the possibility … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 2 · 13 Jun 2016 · 7,383 accessesView PDFCite
Review ArticleOpen accessIn the author namesAutomatic Methods for Generation of Type-1 and Interval Type-2 Fuzzy Membership FunctionsAndréia Alves dos Santos Schwaab, Silvia Modesto Nassar, Paulo José de Freitas FilhoGeneration of membership functions is an important step in construction of fuzzy systems. Since membership functions reflect what is known about the variables involved in a problem, when they are correctly modeled the system will behave in the manner that is expected in the context of the problem being addressed. Since their creation, type-1 membership functions have been used in … …Journal of Computer Science, Vol. 11, Issue 9 · 20 Dec 2015 · 7,297 accessesView PDFCite
