Research ArticleOpen accessIn the abstractA New Polyoxypregnane Glycoside from the Roots of Dregea volubilis (L.f) Benth. ex Hook. f and its Chondroprotective EffectSaksri Sanyacharernkul, Akanit Itghiarbha, Prachya Kongtawelert et al.Problem statement: Dregea genus (Asclepiadaceae) is well known for the rich of steroid pregnane contents and these plants are famous for the potential to be applied as alternative biological activities. Dregea volubilis is the only species of Dregea genus in Thailand. The chemical and biological investigations of this plant are interesting to bioassay-guided fractionation, particularly chondroprotective effect. Approach: The research … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 4 · 31 Dec 2009 · 7,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractCorrelation Between MMP-3, TIMP-3 Expression and Neuronal Apoptosis After Ischemia -Reperfusion Injury in RatesZi Xiaohong, Mutasem Abuhamed, Yuan Yi et al.Matrix metalloproteinases (MMPs) play a central role in many biological processes, such as embryogenesis, normal tissue remodeling, wound healing, and angiogenesis. How MMP3, TIMP3 expression and neuronal apoptosis (Fas, Fas-L and Bcl) may provide detrimental or beneficial actions during the injury and repair processes after cerebral ischemia-reperfusion injury in rates was studied. Adult rats underwent middle cerebral artery occlusion (MCAO) … …American Journal of Immunology, Vol. 3, Issue 2 · 30 Nov 2007 · 7,175 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Cell-Responsive Nanophase Hydroxyapatite for Tissue EngineeringR. Murugan, S. RamakrishnaScaffold plays a critical role in engineering bone tissues by providing necessary structural support for the cells to accommodate and guiding their growth in the three dimensional (3D) space. Therefore, designing scaffold that mimic composition and structural aspects of the bone is of great importance to promote cell adhesion, cell-matrix interactions, osteointegration, tissue formation and continued function. Nanophase hydroxyapatite (HA) … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,163 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Modeling Approach for Collision Avoidance in Robotic SurgeryReza Ramezanifard, Javad Dargahi, Siamak Najarian, Farhad Tabatabai GhomsheWe present a new system that can be used in combination with an array of ultrasonic piezoelectric sensors and has application in surgical navigation procedures. Using the proposed assembly, the maneuverability of the surgical tools can be enhanced and the incidence of potentially damaging contact with non-target tissue can be reduced. The emphasis of our work was based on controlling … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 6,795 accessesView PDFCite
Research ArticleOpen accessIn the abstractAlgorithmization of Electrostatic Model for Solving the Direct Problem of ElectrographyTagirbek Gaidarbekovich Aslanov, Naur Zamirovich Ivanov, Shamil Shamil`evich Anudinov, Tatiana Vladimirovna KarlovaAn analysis of the creation and implementation of algorithms to control cardiological processes occurring in the cardiovascular system using software and hardware diagnostic systems is a required activity. This study considers ways to improve the methods of medical data processing using electronic diagnostic systems, relying on existing methods of mathematical simulation of human body states. This study describes the development … …Journal of Computer Science, Vol. 21, Issue 4 · 7 Mar 2025 · 5,330 accessesView PDFCite
Research ArticleOpen accessIn the abstractTechnique for In-Vivo Measurements of Heart Deformation Using Digital Image CorrelationRonald B. Bucinell, Matthew T. Adams, Mcolisi Dlamini, Leo J. FleishmanMany techniques used to measure the deformation of biological tissue are inadequate for measuring deformations of hearts in vivo. Bull Frogs (Rana Catesbeiana) were double-pithed and dissected to expose the amphibian heart for the measurements conducted in this study. White titanium dioxide powder and black charcoal were applied to the surface of the heart to create an artificial surface pattern … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 14 Dec 2016 · 7,947 accessesView PDFCite
Research ArticleOpen accessIn the abstractNitric Oxide Donors with Therapeutic Strategic in Experimental Schistossomiasis MansoniWander Rogério Pavanelli, Jean Jerley Nogueira da Silva, Carolina Panis et al.Schistosomiasis, an immune disease, remains a major public health problem in endemic area. To determine the influence of Nitric Oxide (NO) on this disease, we tested two compounds (Trans-[Ru(bpy)2(NO)SO3](PF6)-PF6 and Na2[Fe(CN)5(NO)]-SNP, which releases NO when activated by biological reducing agents, in BALB/c mice infected subcutaneously by Schistosoma BH strains. The parasitic activity of NO-donors was evaluated in this model by … …American Journal of Immunology, Vol. 10, Issue 4 · 24 Feb 2015 · 7,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractRADIOSENSITIZATION OF CANCER STEM CELLS: TARGETING TGFβ, NOTCH OR TELOMERASE TO IMPROVE TUMOR RESPONSE O RADIOTHERAPYIgnacio Fernandez-GarciaRadiation resistant cancer stem cells are the main reason for treatment failure and tumor recurrence after cancer radiotherapy. Increasing biological evidences demonstrate that these cells possess the capacity to repair radiation induced DNA damage, protect themselves from radiation derived reactive oxygen species, survive and proliferate after several fractions of radiotherapy and finally, repopulate the heterogeneity of the tumor. Thus, targeting … …Current Research in Medicine, Vol. 5, Issue 2 · 16 Jul 2014 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancement of Nutritional Quality of Wheat (Triticum aestivum) by Metabolic Engineering of Isoflavone PathwayAhmed Mohamed El-Shehawi, Abdelmegid Ibrahim Fahmi, Mona Mohamed Elseehy, Hesham Ahmed NagatyIsoflavones are large group of secondary metabolites produced in legumes such as soybeans. They have essential biological functions as nutraceutical and health functions for human. They are involved in plant resistance to biotic and abiotic stresses, symbiotic relationship with nitrogen-fixing organisms and plant competition (allelopathy). In this report, isoflavonoids were expressed in wheat (Triticum aestivum) via introducing the key enzymes … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,135 accessesView PDFCite
