Review ArticleOpen accessAll words, across the recordNews in Bone Modeling for Customized Hybrid Biological Prostheses DevelopmentRelly Victoria Virgil Petrescu, Raffaella Aversa, Valeria Perrotta et al.The complex biomechanics and morphologies of the femur proximal epiphysis are presented. The nature and fine morphology of the femur head and its structural behavior have been investigated. Isotropic and orthotropic trabecular structures have been associated with oriented compression and tensioned areas of the femur head FEM models. These isotropic/orthotropic trabecular morphologies and their allocations govern the stress and strain … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 14 Jun 2021 · 6,353 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEffects of a Topical Composition of GABA and Microbial Chondroitin Sulfate on Mental Calmness and Brain FunctionMarco RuggieroThis article describes a novel topical composition constituted by Gamma-Aminobutyric Acid (GABA) and microbial chondroitin sulfate. This composition, formulated by the author and manufactured in a certified facility in the United States of America, exhibits potential for non-invasive intervention in anxiety management, sleep quality enhancement and promotion of brain-related functions like meditation and nonlocal consciousness. The core component comprises GABA, … …American Journal of Immunology, Vol. 19, Issue 1 · 8 Mar 2024 · 11,681 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordBiomimetic Finite Element Analysis Bone Modeling for Customized Hybrid Biological Prostheses DevelopmentAversa Raffaella, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Apicella AntonioThe human femur shows a high capacity to withstand external stresses and it is due to the mass distribution, morphology, and orthotropic behaviors of trabecular and cortical bone. Faithful modeling of the femur accounting for bone distribution and material orthotropic behavior is presented. The use of biofidel model is aimed to develop an "in silico" tool that could enable the … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 30 Nov 2016 · 8,986 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordModeling Growth of Microalgae Dunaliella Salina under Different Nutritional ConditionsSergio Santos Jesus, Rubens Maciel FilhoProblem statement: The aim of this study was to find the empirical model that describes the growth kinetics of Dunaliella salina, with low production cost and to estimate parameters of this model. Approach: In this study the strain of D. salina UTEX 200 was cultivated in seawater (0.5 M NaCl) at room temperature with agitation of 150 rpm and luminous … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,021 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPrediction of Tumor Existence in the Virtual Soft Tissue by Using Tactile Tumor DetectorSayyed Mohsen Hosseini, Siamak Najarian, Samira Motaghinasab et al.We proposed a method to investigate the effects of the tumor existence that appear on the surface of the tissue. Finite element analysis provided properties such as the shape, depth, and location of the tumor which are important parameters for physicians to distinguish the correct condition of the patients. Several different cases were created and solved by the ANSYS software … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,986 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordBridging from Cells to Cognition in Autism Pathophysiology: Biological Pathways to Defective Brain Function and PlasticityMatthew P. Anderson, Brian S. Hooker, Martha R. HerbertWe review evidence to support a model where the disease process underlying autism may begin when an in utero or early postnatal environmental, infectious, seizure, or autoimmune insult triggers an immune response that increases reactive oxygen species (ROS) production in the brain that leads to DNA damage (nuclear and mitochondrial) and metabolic enzyme blockade and that these inflammatory and oxidative … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 17,461 accessesView PDF Cite
