Research ArticleOpen accessEvery word in the titleDesign and Modeling the Prosthetic Foot from Suitable Composite MaterialsHasan Saad Mohammed, Jasim Mohammed SalmanThis work concerns developing a composite material, which can be used in manufacturing prosthetic feet with a reasonable cost and satisfying mechanical properties. The characteristics were investigated by mechanical tests of tensile properties and Charpy impact strength. The study of date palm wood and its effects on the mechanical properties of polyethylene have received little attention. It was found that … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 12 Sep 2020 · 7,602 accessesView PDFCite
Case ReportOpen accessEvery word in the titleProsthetic Valve Endocarditis Due to Clostridium Limosum: A Case Report and Review of the LiteratureLok Yung, Carl Urban, Negin Niknam, Glenn TurettClostridium limosum is an anaerobic gram positive rod-shaped bacterium found in soil and can cause infections in a variety of animals. Rarely has this organism caused infections in humans. While clostridial prosthetic valve endocarditis is reported infrequently, we document the first human case of prosthetic valve endocarditis as the sole pathogen, due to Clostrdium limosum. …American Journal of Infectious Diseases, Vol. 15, Issue 4 · 10 Oct 2019 · 7,767 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProsthetic Knee Mechanism Using a Double Locking System as a Safety MeasureEicarl Saynes Vazquez, Esther Lugo GonzálezThe design of a four-link knee prosthesis mechanism with two locking systems activated during the flexion/extension phase is presented. The first is geometric, totally mechanical and activated by the user's weight. The second is variable and is activated automatically when walking on irregular or special surfaces is required. The links' dimensions were selected using the differential evolutionary optimization algorithm to … …Journal of Mechatronics and Robotics, Vol. 8, Issue 1 · 12 Feb 2024 · 5,701 accessesView PDFCite
Case ReportOpen accessIn the keywordsA Case of a Young Patient with Acute Endocarditis and Challenging Diagnostic and Treatment DecisionsPau Rello, Teresa González-Alujas, Laura Escolà-Vergé et al.Despite advances achieved in recent years, Infective Endocarditis (IE) remains a disease associated with high mortality and morbidity. When it involves multiple locations at the same time, deciding the best treatment can become challenging. In some cases, especially in patients with prosthetic valve endocarditis, a definitive diagnosis can be difficult to achieve and multimodality imaging including Positron Emission Tomography/Computed Tomography … …American Journal of Infectious Diseases, Vol. 17, Issue 3 · 9 Jun 2021 · 7,382 accessesView PDFCite
Research ArticleOpen accessIn the keywordsACTINOMYCES NAESLUNDII, A PREVIOUSLY UNDOCUMENTED CAUSE OF INFECTIVE ENDOCARDITIS; WITH LITERARY REVIEWLoren Garrison Morgan, Ashley L. Davis, Paul Poommipanit, Yasir AhmedActinomycotic endocarditis is a rare disease with only 18 documented cases to date. Most of these cases are sub-acute or chronic infections and usually lack the stigmata of classic endocarditis. This article reviews the details of previously published reports of endocarditis due to various species of actinomyces, along with consensus opinion on diagnosis and treatment. We also present our unique … …American Journal of Infectious Diseases, Vol. 10, Issue 3 · 27 Oct 2014 · 6,972 accessesView PDFCite
Review ArticleOpen accessIn the abstractNews 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 · 6,351 accessesView PDFCite
Case ReportOpen accessIn the abstractAltered Passive Eruption: A Combined Perio-Restorative Approach: A Case ReportFarah Antar, Racha Hajj, Maroun Dagher, Elie ZebouniAltered passive eruption is described as a condition in which the relationship between teeth, alveolar bone and the soft tissues creates an excessive gingival display and, in turn, in some circumstances, it may reveal a clinical aspect known as the gummy smile. A 29-year-old male patient presented to a dental clinic in Beirut, Lebanon, complaining about short looking teeth and … …Current Research in Dentistry, Vol. 12, Issue 1 · 27 May 2021 · 7,047 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlexible Stem Trabecular ProsthesesRaffaella Aversa, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Antonio ApicellaThe complex biomechanics and morphology of the femur proximal epiphysis are presented. This specific region in human femur is characterized by a high flexibility compared to that of other primates, since evolved lighter and longer due to the human verticalposition and more balanced loading. The nature and fine morphology of the femur head and its structural behavior have been investigated. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 22 Dec 2016 · 7,855 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiofidel FEA Modeling of Customized Hybrid Biological Hip Joint Design Part II: Flexible Stem Trabecular ProsthesesRaffaella Aversa, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Antonio ApicellaNew biomechanical criteria for the design of biomimetic hip joint prostheses are presented. Biofidel Finite Element Models have been used both to correctly analyze femur physiological and structural behavior and to assess a new design criterion for the development of innovative hybrid biological hip prostheses. Proper identification of isostatic lines and isorigidity regions for the sintered metal trabecular lattices distribution … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 16 Dec 2016 · 8,612 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Playing Surface and Shoe Type on ACL Tears in Soccer PlayersMelissa M. Mansfield, Ronald B. BucinellToday, Anterior Cruciate Ligament (ACL) tears are one of the most prevalent knee injuries, with the occurrence of ACL tears increasing drastically from approximately 80 000 in 2000 to 150 000 in 2011. Although there are many factors that contribute to an ACL tear occurring, certain environmental factors could contribute to the dramatic increase over the past couple decades, especially … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 15 Dec 2016 · 12,888 accessesView PDFCite
