Research ArticleOpen accessIn the abstractCharacteristics of a Novel Highly Thermostable and Extremely Thermophilic Alkalitolerant Amylase from Hyperthermophilic Bacillus Strain HUTBS71Farouk Al-Quadan, Hazem Akel, Rasha NatshiProblem statement: This study reported the purification and characterization of a novel highly thermostable alkaline amylase from a newly isolated Bacillus strain HUTBS71. Approach: The enzyme was purified using ammonium sulfate precipitation, ion exchange and gel filtration chromatography. Results: Maximum amylase activity (72 U mL-1) was obtained at 100°C after 10 min of incubation. The enzyme was purified 24 fold … …OnLine Journal of Biological Sciences, Vol. 9, Issue 3 · 30 Sep 2009 · 7,400 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrical and Magnetoresistive studies Nd doped on La-Ba-Mn-O3 Manganites for Low-field Sensor applicationH. Abdullah, S. A. HalimProblem Statement: Electrical and magnetoresistive properties of the Nd doped (La1-xNdx)0.5Ba0.5MnO3 type samples with 0 ≤ x ≤ 1.0 had been prepared using the solid state reaction. These materials are extensively studied by the substitution of rare-earth compound is to understand the nature of transport phenomena in each system. Approach: The samples were calcined at 900°C for 12 h, pelletized … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormetic Triggers for Intervention in Aging, Disease and TraumaJoan Smith SonnebornHormesis refers to the ability of a chemical or physical agent to condition the physiological state of an organism to tolerate stress with low doses of otherwise harmful agents. Evolutionary evidence shows that the survival and longevity of species hinge on their optimal ability to resist stress challenge. Hormesis is a potent strategy to stimulate latent repair processes to tolerate … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,895 accessesView PDFCite
Research ArticleOpen accessIn the abstractDigital Hardware Implementation of a Neural System Used for Nonlinear Adaptive PredictionHassène Faiedh, Chokri Souani, Kholdoun Torki, Kamel BesbesNeural networks have been widely used for many applications in digital communications. They are able to give solutions to complex problems due to their nonlinear processing and their learning and generalization. Neural networks are one of the key technologies for the communication domain and accordingly a special effort may be expected to be paid to real time hardware implementation issues. … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,763 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 · 6,853 accessesView PDFCite
Research ArticleOpen accessIn the abstractHuman Latrophilin-2 is Expressed in the Cytotrophoblast and Syncytiotrophoblast of Placenta and in Endothelial CellsGunda Herberth, Anke Stein, Jens Glienke et al.Latrophilin-2 is a member of the family of adhesion-GPCRs that is characterised by a long N-terminus which contains motifs identified in proteins involved in cell adhesion. We were interested in determining the expression pattern of human latrophilin-2 and to perform a biochemical characterisation of this protein. The expression pattern of latrophilin-2 was analysed in human organs, tissues and cell lines. … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 8,053 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMRI Observation and Analysis of Muscle Activity During ExerciseLi-Chang Zou, Hong-Wu LiWhile conventional biomechanical testing techniques are able to determine the mechanical characteristics of muscle tissue, they do not offer precise insight into how muscle metabolism and microstructure change in response to various types of exercise activities over the course of time. Using Magnetic Resonance Imaging (MRI) analysis of muscle tissue allows researchers to examine how different levels of intensity affect … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 30 Jul 2026 · 1,025 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordLumbricus rubellus Protein Fraction DLBS1033N Increases Nerve Growth Factor Expression via Tyrosine Kinase ActivationAgung Heru Karsono, Raymond Rubianto Tjandrawinata, Maggy Thenawidjaja SuhartonoNerve injury occurred due to mechanical, thermal, chemical, or ischemic factors. Nerve regeneration is needed for recovery. Schwann cell proliferation and differentiation are important factors in the nerve regeneration process. Schwann cells release neurotrophins in the nerve regeneration process. In this study, Lumbricus rubellus protein fraction DLBS1033N was used as therapeutic protein candidate for nerve regeneration treatments. DLBS1033N treatments promoted … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 1 · 7 Feb 2018 · 9,407 accessesView PDFCite
