Research ArticleOpen accessIn the abstractA Hydroponic System for Purification of Anaerobically Treated Dairy Manure and Production of Wheat as a Nutritional Forage CropA. E. Ghaly, H.A. Farag, M. VermaA hydroponic system was developed and used for purification of an anaerobically treated dairy manure and production of forage crops. The effect of light duration, seeding rate and wastewater application rate on the crop yield and pollution potential reduction were studied. The results indicated that a wheat forage crop can be produced in 21 days from germination to harvest in … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 8,076 accessesView PDFCite
Research ArticleOpen accessIn the abstractInsertion of poly (ethylene glycol)-lipid reduces the liposome-encapsulated hemoglobininduced thrombocytopenic reactionVibhudutta Awasthi, Beth Goins, William T. PhillipsInteraction with platelets has been recognized as a concern in the development of liposome-encapsulated hemoglobin as an oxygen carrier. This reaction causes a significant drop in circulating platelets in a rapid and transient fashion. We studied the effect of lipid bilayer charge on the magnitude of drop in circulating platelets. We also investigated the effect of post-inserted PEG-lipid on this … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 2 · 30 Jun 2007 · 7,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmetine produce Entamoeba histolytica Death by Inducing a Programmed Cell DeathJ.D. Villalba-Magdaleno, R. Rojas, C. Gómez et al.Amoebiasis is a major public health problem in tropical and subtropical countries. Although a number of antiamoebic agents are used for its treatment and the molecular targets of these drugs have been identified, the biochemical and physiological mechanisms that produce trophozoite death are little known. The present study dates the in vitro induction of programmed cell death (PCD) in E. … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,214 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhytoremediation of Anaerobic Digester Effluent for Water Purification and Production of Animal FeedA. E. Ghaly, H.A. FaragThe application of phytoremediation for purification of an anaerobically treated dairy manure and production of forage crops was investigated. Four crops (two cereals and two grasses) were examined for their ability to grow hydroponically and to remove pollutants (nutrients) from dairy wastewater. The preliminary experiments showed that timothygrass and orchardgrass did not perform well as aquatic plants. Only 24 and … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 8,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractHospital Wastewater Treatment Using an Integrated Anaerobic Aerobic Fixed Film BioreactorA. Rezaee, M. Ansari, A. Khavanin et al.The design and operation of wastewater treatment systems for hospital is a challenge for wastewater engineers. In this study, a pilot-scale system integrated anaerobic-aerobic fixed film reactor for hospital wastewater treatment was constructed and its performance was evaluated. The aim of the study was the elimination of organic compounds and a significant reduction of bacteria. The system had been operated … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 8,150 accessesView PDFCite
Research ArticleOpen accessIn the abstractSewage Treatment Plant Sludge: A Source of Potential Microorganism for Citric Acid ProductionParveen Jamal, Md. Zahangir Alam, M. Ramlan et al.This research emphasizes on the utilization of Sewage Treatment Plant (STP) sludge, which is an inexpensive and easily available raw material and a good source for growth of microorganisms because it has enough nutrients and trace elements. This can be considered as an alternative cost effective solution for waste management in addition to the production of a value added product … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 8,940 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncreased Production of Nitric Oxide Contributes to Renal Oxidative Stress in Endotoxemic RatBahar Tunçtan, Belma Korkmaz, Hatice Yıldırım et al.Overproduction of reactive oxygen and nitrogen species leads to oxidative stress and decreased total antioxidant capacity, which is responsible for high mortality from several diseases such as endotoxic shock. Nitric oxide (NO) produced by inducible NO synthase (iNOS) during endotoxemia is the major cause of vascular hyporeactivity, hypotension and multiple organ failure. In this study, we investigated whether increased production … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 8,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractGender Differences in Baseline Levels of Vascular Endothelial Growth Factor in the Plasma of Alaskan Sled DogsScott W. Kemp, Arleigh J. Reynolds, Lawrence K. DuffyAngiogenesis and vasculogenesis are two very important processes in the development and maintenance of mammalian health. In sled dogs, the angiogenic role is to supply and support tissue with ample vasculature, thus providing a route of access for the transportation of essential nutrients, including oxygen and the removal of waste in a sustained fashion. VEGF has been shown to be … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,320 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation and Characterization of Hybrid Organic-Inorganic Composite Material: Polymerization of m-Aminobenzoic Acid-Intercalated Into Zn/Al-Layered Double HydroxidesRasheed M.A.Q. JamhourLayered double hydroxides of aluminum and zinc (Zn/Al-LDH’s) were synthesized directly by hydrolysis at room temperature as reported elsewhere. After characterization, the material was reacted with m-aminobenzoat anion (m-NH2C6H4COO-) which undergoes polymerization in the interlayer space; resulting in the formation of a matrix with polymeric organic macromolecule. The resulting material along with the host LDH’s compound of Zn/Al-Cl was characterized … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,588 accessesView PDFCite
Research ArticleOpen accessIn the abstractMonitoring Water Quality Parameters of the Transboundry River NestosPsilovikos Aris, Margoni Sophia, Psilovikos AntoniosThe Nestos/Mesta river, shared by Greece and Bulgaria, needs monitoring system along its course for sustainable management and environmental preservation. Such a system, known as R.E.MO.S., was installed in the year 2000 and operates since then on a 24 h basis at a station in the river deltas channel. It records water level, water and air temperature, conductivity, redox potential … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,184 accessesView PDFCite
