Review ArticleOpen accessIn the abstractAstrocytes Store for Memory and CognitionMajid Karimi BaghmalekiIn humans, protoplasmic astrocytes are found with high density in the cortex and hippocampus (both parts responsible for memory and cognition) and each astrocyte is in contact with two million of synapses. Astrocytes are responsible for the synaptogenesis and the removal of synapses, which is the basis of learning and memory. The synaptogenesis increases sevenfold with the addition of astrocytes … …Neuroscience International, Vol. 12, Issue 1 · 21 Apr 2021 · 17,209 accessesView PDFCite
Research ArticleOpen accessIn the abstractInclusion of Molasses or Glucose Syrup in Starter Concentrate for Dairy Calves: Effects on Diarrheic CalvesMarcelo Cezar Soares, Carlos Eduardo Oltramari, Marília Ribeiro de Paula et al.Severity of metabolic acidosis and other clinical signs in diarrheic dairy calves fed a starter concentrate containing molasses or glucose syrup as a replacement for corn were evaluated. Thirty-two calves were blocked according to birth weight and were divided into four treatments according to starter concentrate composition: (1) Control, starter concentrate based on corn; (2) 5% of molasses as a … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 1 · 28 Mar 2016 · 7,254 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Nano Silica on the Compressive Strength of Harden Cement Paste at Different Stages of HydrationJustin Montgomery, Taher M. Abu-Lebdeh, Sameer A. Hamoush, Miguel PicornellThis study investigated the compressive strength of hardened cement paste and the formation of Calcium Silicate Hydrate (C-S-H) with the addition of nano silica (SiO2). Compressive strength testing was performed using MTS and Forney testing machines to determine stress-strain curves and compressive strength of the materials. The hydration process and formation of C-S-H and Calcium Hydroxide (CH) was examined using … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 8,333 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating the Role of Fly Ash and Silica Fume in the Cement Hydration ProcessLucas Suarez, Taher M. Abu-Lebdeh, Miguel Picornell, Sameer A. HamoushThis research work investigates the effect of fly ash and silica fume on cement paste hydration. Percentages of each additive were selected to replace the cement by volume to be studied at five different ages using water curing and vacuum curing. These percentages were compared alongside a controlled cement paste without additives. Testing was carried out on 350 samples. Analysis … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 12 Mar 2016 · 8,640 accessesView PDFCite
Research ArticleOpen accessIn the abstractProbing the Substrate Specificity and Intersubunit Interactions of Brevundimonas Diminuta Glutaryl Acylase with Site-Directed MutagenesisMichael Eldarov, Anna Lyashenko, Tatyana Sherbakova et al.Glutaryl-7-ACA acylases (GLA) are industrial enzymes widely used for the production of 7-aminocepahlosporanic acid (7-ACA)-the starting compound for manufacturing of semisynthetic cephalosporin antibiotics. Generation of mutant GLA's with increased activity and stability, capability for single-step conversion of cephalosporin C (CPC) directly to 7-ACA is a promising route to improve the current biocatalytic technologies. In this study GLA from Brevundimonas diminuta … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 3 · 12 Nov 2014 · 8,160 accessesView PDFCite
Research ArticleOpen accessIn the abstractINVESTIGATING EFFECTS OF INTRODUCTION OF CORNCOB ASH INTO PORTLAND CEMENTS CONCRETE: MECHANICAL AND THERMAL PROPERTIESAntonio Price, Ryan Yeargin, Ellie Fini, Taher Abu-LebdehThe purpose of this study was to evaluate the benefits of replacing Ordinary Portland Cement (OPC) with Corncob Ash (CCA) blended cements. The cement industry contributes considerable amount of Carbon Dioxide (CO2) emissions into the atmosphere. The main contribution of CO2 emissions from cement production results from the process of creating Calcium Oxide (CaO) from limestone (CaCO3) commonly known as … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 31 Mar 2014 · 9,813 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECT OF USING STEEL SLAG AGGREGATE ON MECHANICAL PROPERTIES OF CONCRETESultan A. Tarawneh, Emhaidy S. Gharaibeh, Falah M. SarairehThis study presents an evaluation of the physical and mechanical properties and characteristics of steel slag aggregate concrete in comparison with the typical crushed limestone stone aggregate concrete. Hardened concrete consist of more than 70% aggregate due to the high demand in building construction and the increase of the amount of disposed waste material, suppliers and researchers are exploring the … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 10 Feb 2014 · 8,055 accessesView PDFCite
Research ArticleOpen accessIn the abstractStem Cells in Traumatic Brain InjurySamuel Dobrowolski, Guilherme LepskiTraumatic Brain Injury (TBI) is a devastating clinical condition that often causes permanent incapacity, especially in the younger population. The clinical relevant of TBI justifies the scientific interest in the pathophysiology of TBI, as well as in protective effects and development of treatment options. Stem cells have the ability to induce neuroprotection and neural repair inflammatory suppression, causing tissue reconstruction … …Neuroscience International, Vol. 4, Issue 1 · 12 Apr 2013 · 7,564 accessesView PDFCite
Research ArticleOpen accessIn the abstractBooming Medical Tourism and Economic IndicesRamalingam ShanmugamGlobalization in this 21st century unifies nations. The globalization impacts positively to promote trade and services among the nations but it could also harm economic growth and technological innovations in nations as their capital are drained to elsewhere. On its own merits, the globalization is a true manifestation of an open economy. The medical profession is not immune to this … …International Journal of Research in Nursing, Vol. 3, Issue 2 · 30 Mar 2013 · 7,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractProperties of Fly Ash Based Coconut Fiber CompositeK. Saravana Raja Mohan, P. Jayabalan, A. RajaramanThe present paper reports the results of a study undertaken in enhancing properties of fly ash concrete composites-FMCC with locally available natural fiber. In this context a composite with fly ash, concrete and treated coconut fibers-available in plenty in rural areas of India-can be a good proposition and with this background, experimental investigation to study the effects of replacement of … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 20 Feb 2012 · 9,169 accessesView PDFCite
