Research ArticleOpen accessIn the abstractProduction and Roles of Glial Tissue Inhibitor of Metalloproteinases-1 in Human Immunodeficiency Virus-1-Associated Dementia Neuroinflammation: A ReviewC. Chao, A. GhorpadeProblem statement: Tissue Inhibitor of Metalloproteinases-1 (TIMP-1) and its cognate targets, the Matrix Metalloproteinases (MMPs), were differentially expressed in human brain samples with or without HIV-1 infection or HIV-1 Encephalitis (HIVE). Approach: A through literature review demonstrated that cell culture models of Central Nervous System (CNS) cell types had been used to illustrate the intricate temporal patterns of TIMP-1/MMP expression, … …American Journal of Infectious Diseases, Vol. 5, Issue 4 · 31 Dec 2009 · 6,957 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparison between Brain Tissue Gray and White Matters in Tension Including Necking PhenomenonSina Mehdizadeh, Mehdi Khoshgoftar, Siamak Najarian et al.Characterizing the differences between the mechanical properties of brain tissue gray and white matters is of importance in biomechanics of brain tissue and may find a variety of different applications in medicine. In this study, a comparison has been made between mechanical behavior of bovine brain tissue white and gray matters. Through a linear elastic theory and using Bridgman method, … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,843 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMetals Concentrations in Tissues of Tilapia gallier, Crarias lazera and Osteoglossidae Caught from Alau Dam, Maiduguri, Borno State, NigeriaG.A. Dimari, F.I. Abdulrahman, J.C. Akan, S.T. GarbaAn analysis of intestine, liver, stomach and gill tissue concentrations of heavy metals (Cu, Co, Pb, Cr, Mn, Fe, Ni, Cd and Zn) in three commercially important fish species (Tilapia gallier, Crarias lazera and Osteoglossidae. caught within Alau Dam between the periods of January to August, 2007. These heavy metals were determined using Perkin-Elmer AAnalyst 300 Atomic Absorption Spectroscopy (AAS). … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,489 accessesView PDF Cite

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 · 7,182 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHistological Study of the Caecal Tonsil in the Cecum of 4- 6 Months of Age White Leghorn ChicksM. Rezaian, S. HamediCecum, the largest part of chicken’s large intestine, has an important role in liquid absorption and cellulose digestion. It acts as a defensive organ as well due to the presence of large masses of diffuse and nodular lymphatic tissue in lamina propria and sub mucosa. The cecal tonsil activity has been proved to be depended on the activity of bursa … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 8,074 accessesView PDF Cite

Research ArticleOpen accessIn the abstractToll-Like Receptor (TLR) 2 and TLR4 Gene Expression in Canine HeartA. Linde, F. Blecha, T. MelgarejoToll-like receptors (TLRs) are archetypal pattern recognition receptors of immediate importance for an efficacious innate immune response. TLRs exhibit marked differential tissue activity and their levels within a discrete cell type can be highly dynamic. Of 13 known mammalian paralogues, three TLRs have been identified in the dog. Although cardiac TLR expression has been reported in other species, this study … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 6,924 accessesView PDF Cite

Research ArticleOpen accessIn the abstractWound Healing Process of Uncomplicated “Rusterholz” Ulcer, Following Treatment by Wooden Block and Hoofgel® in Bovine Hoof: Histopathological AspectsH. Azarabad, I. Nowrouzian, E. Soleymani et al.A broad and very detailed histopathological knowledge on cutaneous wound healing particularly in human skin is available, but few studies have documented this event in bovine claw sole ulcers. It seems the mechanism of wound healing might be basically the same followed by second intention healing which is finished in a period of time by formation of granulation tissue in … …American Journal of Animal and Veterinary Sciences, Vol. 1, Issue 2 · 31 Dec 2006 · 7,853 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMultiple Antibiotic Resistances of Vibrio Isolates from Coastal and Brackish Water AreasS. Manjusha, G. B. Sarita, K. K. Elyas, M. ChandrasekaranAn experiment was designed to assess the occurrence of multiple antibiotic resistances in Vibrio spp. from different (brackish and marine) environments. Water samples from nine marine landing sites and two coastal inland aquaculture farms were screened for the Vibrio spp. and assessed their resistance to twenty-two different antibiotics, which are commonly encountered in the aquatic ecosystem. Tissue samples (shrimp, mussel … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 4 · 31 Dec 2005 · 7,082 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRelationships between Heavy Metal Concentrations in the American Oyster (Crassostrea virginica) and Metal Levels in the Water Column and Sediment in Apalachicola Bay, FloridaDennis A. Apeti, Larry Robinson, Elijah JohnsonThis study aims to assess baseline concentrations of heavy metals (Cd, Cr, Cu, Pb and Zn) in the oyster soft tissue as they relate to concentrations in the water column (particulate phase) and sediment in Apalachicola Bay. In order to conduct these assessments, a total of 360 samples, collected in two seasons (winter and summer) and were analyzed using atomic … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,345 accessesView PDF Cite

Research ArticleOpen accessIn the abstractResidues Depletion Study and Withdrawal Period Determination of Sulphadiazine and Trimethoprim Premix in PigsPanagiotis Dimitrios Katsoulos, Lydia Dritsa, Georgios Christodoulopoulos et al.The emergence and spread of antibiotic resistant human pathogens have been directly linked to the use of antibiotics in livestock production. The purpose of this study was to detect and quantify the concentration of the residues of Sulphadiazine (SDZ) and Trimethoprim (TMP) in edible tissues of pigs and to determine the withdrawal period after oral administration of OPTIPRIME® premix 40%, … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 1 · 12 Feb 2013 · 8,362 accessesView PDF Cite
