Research ArticleOpen accessEvery word in the titleNumerical Solution For Frank-Kamenetskii And Activation Energy Parameters in Reactive-Diffusive Equation with Variable One-Exponential FactorO. K. Koriko, A. J. OmowayeIn this study, we considered a steady state, exothermic chemical reaction, taking the diffusion of the reactant into account and assuming an Arrhenius temperature dependence with variable pre-exponent factor. Numerical solution is constructed for the governing nonlinear boundary value problem using finite difference scheme .The effect of Frank-Kamenetskii, activation energy parameter and pre-exponent factor on the temperature were also examined, … …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 6,920 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLumbricus 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
Research ArticleOpen accessEvery word in the titleApplication of MultiScale Hidden Markov Modeling Wavelet Coefficients to fMRI Activation DetectionFangyuan Nan, Yaonan Wang, Xiaoping MaProblem Statement: The problem of detection of functional magnetic resonance images (fMRIs), that is, to decide active and nonactive regions of human brain from fMRIs is studied in this paper. fMRI research is finding and will find more and more applications in diagnosing and treating brain diseases like depression and schizophrenia. At its initial stage fMRI detection are pixel-wise methods, … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,546 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIn vitro Activation of Human and Rat Lymphocyte and Macrophage Functions by NorepinephrineRicardo Gomez-Flores, Diana Caballero-Hernandez, Richard J. Weber et al.Norepinephrine (NE) has been associated not only with increasing blood pressure, atherosclerosis, heart disease, and other life threatening conditions, but also with altering immune responses by influencing leukocyte functions. In the present study, we evaluated the in vitro effects of NE on rat thymic lymphocyte and human peripheral blood mononuclear cells (HPBMC) functions. We observed that NE marginally, but significantly … …American Journal of Immunology, Vol. 1, Issue 4 · 31 Dec 2005 · 7,075 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSelective Lymphocyte Activation and Inhibition of In Vitro Tumor Cell Growth by Novel MorphinansRicardo Gomez-Flores, Kimberly R. Vietti, William J. Dunn et al.Opioids can suppress immune functions and increase susceptibility to developing cancer and infectious diseases. Recently, novel opioid compounds have been synthesized that lack immunosuppressive effects. We evaluated the effects of morphinans with substituted pyrimidine (methyl, phenyl, hydroxy, and amino groups) and pyrazole groups on in vitro rat thymic lymphocyte and splenic macrophage functions, and tumor cell growth. We observed that … …American Journal of Immunology, Vol. 2, Issue 1 · 5 Mar 2005 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThermal Inactivation and Kinetic Characterisation of Peroxidase from Leaves of Brassica chinensis L.Youru Huang, Keyu Rong, Shiman Zhao et al.As one of the perennial vegetable varieties grown in the south of Yangtze River in China, Brassica chinensis L. can be produced and supplied to the market all year round and has high economic value. However, there is little direct literature on postharvest heat treatment of Brassica chinensis L. In this study, Peroxidase (POD) was extracted from Brassica chinensis L. … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 12 Jul 2024 · 4,768 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Effect of Gliflozin Therapy on TNF-α Secretion by Cultured Monocytes in Patients with DiabetesTatiana Vladimirovna Kirichenko, Leyla Azimovna Bochkareva et al.Currently it’s well established that chronic inflammation is a key pathogenetic mechanism in the development of Type 2 diabetes. The study aims to explore the inflammatory response of monocytes in diabetic patients compared to healthy subjects, focusing on TNF-α and to investigate the impact of SGLT2 inhibitors on monocyte inflammation. The study included 20 patients with newly diagnosed type 2 … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 15 Feb 2024 · 4,819 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPunicalagin Suppresses Mediators Involved in Labor Onset and Progression in vitroCaitlyn Nguyen-Ngo, Jane C Willcox, Martha LappasSpontaneous preterm birth is the leading cause of neonatal morbidity and mortality. Inflammation plays a central role in the activation of myometrial contractions and rupture of fetal membranes associated with spontaneous preterm birth. The pomegranate polyphenol punicalagin is known to possess anti-inflammatory properties. In this study, we aimed to determine the effect of punicalagin on pro-inflammatory and pro-labor mediators in … …American Journal of Immunology, Vol. 17, Issue 1 · 22 Dec 2021 · 7,609 accessesView PDFCite
Research ArticleOpen accessIn the keywordsINCREASING ADSORPTION OF ACTIVATED CARBON FROM PALM OIL SHELL FOR ADSORB H2S FROM BIOGAS PRODUCTION BY IMPREGNATIONWasan Phooratsamee, Kanokorn Hussaro, Sombat Teekasap, Jongjit HirunlabhBiogas is the combustible gas produced through a biological process, known as anaerobic digestion which is the process operated at low-temperature and without air. Biogas consists of 55-80% CH4, 20-45% CO2 with trace amount of H2S and other impurities. Common H2S removal technologies from biogas fall into one of adsorption on a solid such as iron oxide based materials, activated … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 16 Aug 2014 · 7,670 accessesView PDFCite
