Research ArticleOpen accessIn the abstractNew Mesogenic Schiff Base Esters with Polar Chloro Substituent: Synthesis, Thermotropic Properties and X-Ray Diffraction StudiesSie-Tiong Ha, Lay-Khoon Ong, Yasodha Sivasothy et al.Problem statement: Many studies have been conducted on the Schiff base’s alkyl and alkyloxy possessing terminal halogen substituent. However, the thermotropic properties of Schiff base’s ester (or alkanoyloxy) with chloro terminal group remained unstudied. Approach: Synthesis a series of new Schiff base ester possessing polar chloro group and investigate its mesomorphic properties. The title compounds were prepared via condensation and … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 12,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudies on Emergence of Drug Resistance in HIV Associated Bacterial Urinary Tract InfectionsS. D. Deokar, M. G. BodhankarProblem statement: This study was designed to document the prevalence of HIV associated urinary tract infections in Barshi Tahsil. Such studies had not been researched out before in this region. Approach: The study included samples from 123 HIV reactive and 40 HIV non-reactive patients. In both, mid stream samples were collected and processed to examine for bacterial opportunistic pathogens. The … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 8,472 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreliminary Study of Phylogenetic Relationship of Rice Field Chironomidae (Diptera) Inferred From DNA Sequences of Mitochondrial Cytochrome Oxidase Subunit ISalman A. Al-Shami, M.N. Siti Azizah, Che Salmah Md Rawi, Abu Hassan AhmadProblem statement: Chironomidae have been recorded in rice fields throughout the world including in many countries such as India, Australia and the USA. Although some studies provide the key to genera level and note the difficulty of identifying the larvae to species level. Chironomid researches have been hindered because of difficulties in specimen preparation, identification, morphology and literature. Systematics, phylogenetics … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,524 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiochemical and Genetic Responses of Fungi to the Toxic Effect of Synthetic and Natural FungicidesMarÍa-Elena Báez-Flores, Rosalba Troncoso-Rojas, Martin-Ernesto Tiznado-HernándezThe objective of the present review is to analyze the molecular basis of fungicide resistance mechanism to both synthetic fungicides and the natural fungicides isothiocyanates. The review is focused mainly on Alternaria sp., but whenever available, similar studies in other fungi have been included. Fungal resistant strains to dicarboximide and phenylpyrrole fungicides have been found to contain mutations in one … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,122 accessesView PDFCite
Research ArticleOpen accessIn the abstractAge-Dependent Variation of Telomere Length and DNA Damage in ChickenMaxim S. Makarenko, Alexander V. Usatov, Lyubov V. Getmantseva et al.Birds are unique models for molecular studies on aging processes and cellular senescence because of their slow rates of aging and comparatively long life spans among homoeothermic animals. The study aimed to examine the relative telomere length and amount of nuclear, mitochondrial DNA lesions in hens of different ages and to find out the correlation between these biomarkers of aging. … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 14 Dec 2017 · 7,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntracellular L-Asparaginase from Bacillus sp. PG02: Purification, Biochemical Characterization and Evaluation of Optimum pH and TemperatureFatemeh Izadpanah Qeshmi, Mahsa Rahimzadeh, Sedigheh Javadpour, Manijeh PoodatBacterial L-asparaginases are amidohydrolases that act on L-asparagine and produce L-aspartate and ammonia. These enzymes have been used in treatment of lymphoblastic leukemia. In the present study, a novel strain, Bacillus sp. PG02 was explored for the production of intra-cellular L-asparaginase enzyme. The nitrogen source for L-asparaginase production was L-asparagine. New intracellular L-asparaginase was purified using ion exchange chromatography and … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 26 Nov 2015 · 7,484 accessesView PDFCite
Research ArticleOpen accessIn the abstractFungal Concentrations in Dust Samples of Animal Rearing Houses of Bangalore, IndiaPavan RangahanumaiahFungal concentrations in dust samples analyzed by molecular methods were carried out of animal rearing house at Hessaraghatta village, Bangalore. Handy air sampler EnviroTech-APM 821 was used to collect the dust samples in triplicate and sampling time was limited to eight hours. The sampled filter papers were used for the assay of DNA extracted from all the four animal rearing … …Current Research in Microbiology, Vol. 6, Issue 1 · 8 Jun 2015 · 7,537 accessesView PDFCite
Research ArticleOpen accessIn the abstractPRODUCTION AND CHARACTERIZATION OF MONOCLONAL AND POLYCLONAL ANTIBODY AGAINST RECOMBINANT OUTER MEMBRANE PROTEINMahdi Fasihi-Ramandi, Amir Nedjad-Moghaddam, Fatemeh Arabsalmany et al.There are many studies related to immunological and molecular methods for diagnosis of Vibrio cholera (V. cholerae). However, most assays dependent on enrichment of culture of bacteria, which need more time and involves the use of costly equipment and reagents. In this study Balb/c mice were immunized with recombinant Outer Membrane Protein (rOMPw) of vibrio cholerae and splenocytes of hyper … …American Journal of Immunology, Vol. 10, Issue 1 · 26 Apr 2014 · 7,444 accessesView PDFCite
Research ArticleOpen accessIn the abstractEMERGING METRONIDAZOLE RESISTANCE IN ANAEROBES AND MAPPING THEIR SUSCEPTIBILITY BEHAVIOURManu Chaudhary, Anurag PayasiIn the present study, anaerobic clinical isolates of Bacteroides fragilis, Escherichia coli, Staphylococcus aureus and Yersinia enterocolitica were obtained from different clinical specimens and were subjected to molecular typing to detect the gene encoding metronidazole resistance in these isolates. Subsequently, antibacterial activity of drugs was tested against the selected clinical isolates. A total of 53 clinical isolates involving 18 obligate … …American Journal of Infectious Diseases, Vol. 10, Issue 2 · 12 Apr 2014 · 9,196 accessesView PDFCite
