Research ArticleOpen accessIn the abstractAnti-Oxidant and Enzyme-Inhibitory Potential of Marine StreptomycesT. Revathy, M. A. Jayasri, K. SuthindhiranMarine actinomycetes are potential source for the discovery of novel compounds and enzymes. Though extensive research on marine actinomycetes is underway globally, the actinomycetes research from Indian marine ecosystem is unexplored and understudied. Hence, the present research is focussed on the screening of bioactive compounds from marine actinomycetes isolated from Indian coastal region. This study is designed to determine the … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 7,242 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransformation of Lesquerella Fendleri with the New Binary Vector pGPro4-35SGrace Q. Chen, Roger Thilmony, Jiann-Tsyh LinProblem statement: Crop genetic engineering requires the use of various promoters to control the expression of introduced transgenes. Some of the binary vectors currently available for promoter characterization in dicotyledonous plants have pitfalls due to their construction, such as containing a selectable marker cassette with enhancer sequences that can potentially interfere with the expression specificity of nearby promoters. Also, many … …OnLine Journal of Biological Sciences, Vol. 11, Issue 3 · 19 Jan 2012 · 7,428 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Rumen Acid Load on Postpartum Performance and Blood Metabolic Responses in Transition Holstein CowsSadjad Danesh Mesgaran, Alireza Vakili, Alireza Heravi Moosavi, Ghasem KoolabadiProblem statement: The transition period is the most stressful time in the production cycle of a dairy cow because of depressed feed intake, endocrine and metabolic changes at parturition. The aim was to determine the effect of rumen acid load on postpartum performance and metabolic parameters in transition Holstein cows. Approach: The Acidogenicity Values (AV) of the diets were determined … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 25 May 2011 · 7,444 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Calcium Channel Blocking Activity of 1, 4-Dihydropyridine Derivatives Containing Ester Substitute and Phenyl Carbamoyl GroupBassem Sadek, Khairi Mustafa Salem Fahelelbom, Laurentiu Morusciag, Sigurd ElzProblem statement: Several studies on the synthesis of new nifedipine analogs have been carried out, but the literature reveled that no study on the synthesis and calcium channel blocking activity of the substituted ester with an amide (5-phenylcarbamoyl) moiety has been reported. Approach: Six new derivatives of m-nifedipine have been successfully synthesized by substituting an ester moiety with an amide … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 8,253 accessesView PDFCite
Research ArticleOpen accessIn the abstractInhibition of U6 snRNA Transcription by PTENStephanie Cabarcas, Kounosuke Watabe, Laura SchrammProblem statement: RNA polymerase III (RNA pol III) is responsible for transcribing many of the small structural RNA molecules involved in RNA processing and protein translation, thereby regulating the growth rate of a cell. RNA pol III transcribes both gene internal (tRNA) and gene external (U6 snRNA) promoters and proper initiation by RNA polymerase III requires the transcription initiation factor … …OnLine Journal of Biological Sciences, Vol. 10, Issue 3 · 30 Sep 2010 · 8,557 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification and functional characterization of a novel lysine-rich protein from Entamoeba histolyticaAlka Mehra, Sudha Bhattacharya, Alok BhattacharyaIn an attempt to understand the role of genes with no known function, in the protozoan parasite Entamoeba histolytica, an analysis of the proteome was carried out and a Lysine-Rich protein (KRP) was identified for further study. This protein has a modular structure with four domains and was found to be expressed and localized to the cell surface of E. … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 7,709 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Murine Charged Multivesicular Body Protein 2A, CHMP2A Interacts with the 5' and 3' Terminal Regions of Dengue Virus Complementary Minus-strand RNASuchita Chaudhry, Sathyamangalam Swaminathan, Navin KhannaDengue (DEN) viruses, of which there are four distinct serotypes (DEN-1, -2, -3 and –4), belong to the Flaviviridae family. Their ‘plus’ sense RNA genomes contain Non-Translated Regions (NTRs) at their 5’ and 3’ ends. Replication of viral genomic RNA, which takes place in close association with host cell membranes, involves the initial synthesis of the complementary minus sense RNA … …American Journal of Infectious Diseases, Vol. 2, Issue 1 · 31 Mar 2006 · 7,317 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffects of a Cyclachaena Xanthiifolia Extract on Trematodes Opisthorchis Felineus: An in Vitro StudyDenis Ponomarev, Elena Khramova, Natalia Gubanova et al.Cyclachaena xanthiifolia is a phytochemically rich invasive weed with documented allelopathic properties, making it a candidate source of bioactive compounds with potential medicinal applications. This study investigated the anthelmintic activity of a crude aqueous-ethanolic extract of C. xanthiifolia (CxEt), prepared from equal proportions of leaves and seeds, against the trematode Opisthorchis felineus in vitro. The effects of CxEt on the … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 1 Jun 2026 · 1,253 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBond Strength of Bioactive vs. Conventional Resin Composites on Dentin Cleaned with Ozonated Water: An In Vitro StudyFernanda Rafaela Ribeiro, Anna Caroliny Detogni, Julio Katuhide Ueda et al.This study aimed to compare the micro tensile bond strength (μTBS) of bioactive and conventional resin composite to human dentin after the use of ozonated water (AO) as a cavity cleaning solution. A total of 32healthy human third molars were randomly assigned to four groups (n = 8)based on the type of composite and dentin cleaning. The first group received … …Current Research in Dentistry, Vol. 16, Issue 1 · 9 Jun 2025 · 6,319 accessesView PDFCite
