Research ArticleOpen accessIn the abstractChitinolytic Bacteria Isolated from Chili Rhizosphere: Chitinase Characterization and Its Application as Biocontrol for Whitefly (Bemisia tabaci Genn.)Nisa Rachmania Mubarik, Irni Mahagiani, Amaryllis Anindyaputri et al.Problem statement: Chitin, a common constituent of insect exoskeleton, could be hydrolyzed by chitinase. The research was conducted to screen chitinolytic rhizobacteria isolated from rhizosphere of chilli pepper and to determine their chitinase activity in degrading chitin of whitefly, Bemisia tabaci Genn. (Hemiptera: Aleyrodidae). Whitefly is recognized as an important pest on many crops including chilli pepper. Approach: Screening and … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 11 Nov 2010 · 18,538 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMolecular Diagnosis of Toxoplasma gondii in Free-Range Chickens (Gallus gallus) Sold at Fairs in the Metropolitan Region of Macapá–AP (Brazil)Paulo Tarso Tavares Santana, Washington Luiz Assunção Pereira, Rafaelle Casseb Guimarães et al.The informal commercialization of free-range poultry in open markets poses potential food safety risks regarding zoonotic pathogens. This investigation molecularly and histopathologically screened for Toxoplasma gondii in 36 free-range chickens acquired from 12 prominent markets in metropolitan Macapá, Amapá State. Paired heart and brain tissue samples from each animal were processed via conventional PCR and conventional histology. The pathogen was … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 2 · 2 Jul 2026 · 1,075 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStructural Characterization at the Atomic Level of a Molecular Nano-Machine: The State of the Art of Helicobacter Pylori Flagellum OrganizationIvana Pulić, Valentina Loconte, Giuseppe ZanottiMotility is fundamental for success in colonization and survival of the human pathogen H. pylori, the bacterium that colonizes about half of the human population. Motility is achieved through flagella. In this review the present structural knowledge about the organization of H. pylori flagella is summarized, considering not only the structure of its proteins, but also what is known about … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 3 · 12 Nov 2014 · 8,310 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCHARACTERIZATION OF MARKOV-BERNOULLI GEOMETRIC DISTRIBUTION RELATED TO RANDOM SUMSMohamed Gharib, Mahmoud M. Ramadan, Khaled A.H. Al-AjmiThe Markov-Bernoulli geometric distribution is obtained when a generalization, as a Markov process, of the independent Bernoulli sequence of random variables is introduced by considering the success probability changes with respect to the Markov chain. The resulting model is called the Markov- Bernoulli model and it has a wide variety of application fields. In this study, some characterizations are given … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 31 Mar 2014 · 6,706 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCytotoxic and Antimicrobial Potential of Actinomycete Species Saccharopolyspora salina VITSDK4 Isolated from the Bay of Bengal Coast of IndiaK. Suthindhiran, K. KannabiranProblem statement: Although the diversity of marine Actinobacteria have been studied and biotechnologically exploited throughout the world, the studies on marine actinobacteria in Indian peninsula are largely unexplored. Of 9 maritime states in India, only 4 states have been extensively studied for the diversity of actinobacteria. Further, the studies on bioactive actinomycetes from saline soil are very scanty. In the … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 11,440 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSpecialization of Recursive Predicates from Positive Examples OnlyMoussa DembaProblem statement: Given an overly general (definite) program P and its intended semantics Φ (the programmer’s intentions) where P does not satisfy Φ, find out a new version P’ of P such that P’ satisfies Φ. Approach: We proposed an approach for correcting overly general programs from positive examples by exploiting program synthesis techniques. The synthesized program, P’, is a … …Journal of Computer Science, Vol. 6, Issue 6 · 30 Jun 2010 · 6,854 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnhanced Survival and Nodule Occupancy of Pigeon pea Nodulating Rhizobium sp. ST1 expressing fegA Gene of Bradyrhizobium japonicum 61A152Falguni R. Joshi, Dhwani K. Desai, G. Archana, Anjana J. DesaiProblem statement: Rhizobial isolates belonging to genera (Rhizobium sp. and Mesorhizobium sp.) in our laboratory produced only catecholate type of siderophores. Although FhuA and FegA (ferrichrome receptors) homologs were found to be present in the sequenced genomes of few rhizobia (e.g., 1 in R. etli and 2 in Mesorhizobium sp. BNC1), laboratory isolates of the corresponding genera failed to utilize … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 30 Jun 2009 · 7,865 accessesView PDF Cite

Research NotesOpen accessAll words, across the recordAnalyses of the Interleukin32 Transcript Variants in Breast Cancer Cell LinesKayla Burrell, Audrey PlayerRecent data show the IL32 gene has at least nine transcript variants. The aim of this current study is to characterize the different transcript variants based on the latest sequencing data deposited in the National Center for Biotechnology Information (NCBI) and determine which variants are responsible for the differential pattern of gene expression previously observed in MCF7 compared to MDA … …American Journal of Immunology, Vol. 12, Issue 4 · 31 Oct 2016 · 6,949 accessesView PDF Cite
