Research ArticleOpen accessIn the abstractSoybean Response to 1-Aminocyclopropane-1-Carboxylate Deaminase-Producing Pseudomonas under Field Soil ConditionsEdi Husen, Aris Tri Wahyudi, Antonius Suwanto, GiyantoProblem Statement: 1-Aminocyclopropane-1-Carboxylate (ACC) deaminase-producing bacteria have been known to promote plant growth by decreasing ethylene inhibition of various plant processes. However, their efficacy under field soil conditions may vary depending on the range and variability of the environmental factors. This study examined the ability of eight promising isolates of ACC deaminase-producing Pseudomonas to enhance soybean growth under acidic and … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 24 Jun 2011 · 8,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractOsmolarity of Coconut Water (Cocos nucifera) Based Diluents and their Effect Over Viability of Frozen Boar SemenBottini Luzardo, M. Centurion Castro, F. Alfaro Gamboa et al.Problem statement: Boar sperm cells are sensitive to the freezing process, which compromises viability of frozen-thawed sperm. In a constant search for minimizing or suppressing sperm cell damage caused by the temperature and osmolarity changes during the freezing process, crioprotective and antioxidant substances have been added to the freezing media, such as coconut water, in order to increase the viability … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,121 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment on the Effect of Formulative Materials on the Viability and Efficacy of Serratia marcescens-a Biocontrol Agent Against Fusarium oxysporum F. sp. cubense race 4A. S. Y. Ting, M. T. Fang, C. S. TeeProblem statement: Application of biocontrol agents to the field in pre-existing free-cell forms often results in poor cell viability which subsequently affects their efficacy in suppressing pathogen development. There is therefore a need to bioformulate these biocontrol agents not just to enhance their field potential, but for easy storage, delivery and application as well. Approach: In this study, the bioformulations … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,474 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification and Antiproliferative Activity Evaluation of a Series of Triterpenoids Isolated from Flueggea virosa (Roxb. ex Willd.)Sod Monkodkaew, Chatchanok Loetchutinat, Narong Nuntasaen, Wilart PompimonProblem statement: Medicinal plants derived anticancer were now being subjects of many research groups especially, the secondary metabolite triterpenoids trees which had enormous potential to inspire and influence modern antiproliferative research. The study aimed to investigate the chemical constitution and their potential use as antiproliferative activity of purified compounds derived from F. virosa. Approach: The F. virosa was selected and … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 30 Oct 2009 · 7,633 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiatrizoate, Iopromide and Iotrolan Enhanced Cytotoxicity of Daunorubicin in Multidrug Resistant K562/adr Cells: Impaired the Mitochondrial and Inhibited the P-Glycoprotein FunctionNitaya Snitwongse Na Ayudhya, Samlee MankhetkornMultidrug resistance was an obstacle in cancer chemotherapy because the cells decreased their intracellular drug accumulation by energy-dependent compounds efflux pumps such as P-glycoprotein (P-gp). This study observed some iodinated radiographic contrast media, diatrizoate, iopromide and iotrolan affected the cellular energetic state and the kinetics of P-gp in drug-sensitive K562 and drug resistant K562/adr cell lines using spectrophotometer and spectrofluorometer. … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of D- and L-Glucose and Mannitol on Retinal Capillary Cells: Inhibition by Nanomolar AminoguanidineYongxin Yu, Wei Li, Barbara Wojciechowski et al.Hyperglycemia may contribute directly to pericyte loss and capillary leakage in early diabetic retinopathy. To elucidate relative contributions of glycation, glycoxidation, sugar autoxidation, osmotic stress and metabolic effects in glucose-mediated capillary damage, we tested the effects of D-glucose, L-glucose, mannitol and the potentially protective effects of aminoguanidine on cultured bovine retinal capillary pericytes and endothelial cells. Media (containing 5 mM … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,751 accessesView PDFCite
Research ArticleOpen accessIn the abstractClozapine and its Major Stable Metabolites, N-desmethylclozapine and Clozapine N-oxide do not Affect Human Bone Marrow Stromal Cells in vitroAvril Pereira, Brian DeanTreatment of refractory schizophrenia with the atypical antipsychotic drug clozapine is associated with life-threatening agranulocytosis, characterised by a drop in neutrophil count. Theoretically, toxicity may be accounted for by direct action of parent drug or one of its stable metabolites on bone marrow stroma given importance of these cells to neutrophil maturation. Effects of clozapine, N-desmethylclozapine and clozapine N-oxide on … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 1 · 31 Mar 2006 · 7,111 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarly Cellular Responses of Purine Nucleoside-mediated Protection of Hypoxia-induced Injuries of Neuronal PC12 CellsBettina Tomaselli, Valerie Podhraski, Günther Böck, Gabriele Baier-BitterlichHypoxia in brain may lead to cell death by apoptosis and necrosis. In parallel adenosine, a powerful endogenous neuroprotectant is formed. We wanted to investigate the effect of adenosine and its purine nucleoside relatives, inosine and guanosine on early cellular responses to hypoxia. O2-sensitive neuronal PC12-cells were subjected to chemical hypoxia induced with rotenone, an inhibitor of mitochondrial complex I. … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,858 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Immunomagnetic Separation Method for Viable Salmonella Typhimurium Detected by Flow CytometryShakil Ahmed, Horst-Günter Rubahn, Helmut ErdmannA very small number of bacterial pathogens may have fatal effects on food safety. In spite of having great advancements in bioanalytical methods, most of the accepted detection methods are still cultivation based and thus time consuming. This leads to an intense need for efficient and rapid methods for detection of food-related bacteria. In this study, a flow cytometry based … …OnLine Journal of Biological Sciences, Vol. 16, Issue 4 · 25 Nov 2016 · 7,578 accessesView PDFCite
