Research ArticleOpen accessIn the abstractBioaccumulation of Arsenic by FungiAdemola O. AdeyemiProblem statement: Arsenic is a known toxic element and its presence and toxicity in nature is a worldwide environmental problem. The use of microorganisms in bioremediation is a potential method to reduce as concentration in contaminated areas. Approach: In order to explore the possible bioremediation of this element, three filamentous fungi-Aspergillus niger, Serpula himantioides and Trametes versicolor were investigated for … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,890 accessesView PDFCite
Research ArticleOpen accessIn the abstractCefepime Monotherapy is as Effective as Ceftriaxone Plus Amikacin in Pediatric Patients with Cancer and High-Risk Febrile Neutropenia: A Randomized ComparisonCarlos Alberto Pires Pereira, Antonio Sérgio Petrilli, Fabianne Altruda Carlesse et al.The empirical use of antibiotic therapies is widely accepted in patients with fever and neutropenia during cancer chemotherapy. The use of intravenous monotherapy with broad-spectrum antibiotics in patients with high-risk of complications is an appropriate alternative. However, few data are available in pediatric patients. We conducted a prospective, randomized, open study in patients with lymphoma or leukemia who had fever … …American Journal of Infectious Diseases, Vol. 4, Issue 4 · 31 Dec 2008 · 7,404 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Manganese Uptake by Wetland PlantsA.E. Ghaly, A. Snow, M. KamalThe aim of this study was to assess the kinetics of Mn removal by broad-leaved cattail, soft stem bulrush, soft rush and wool grass plants from contaminated wastewater under laboratory conditions. The approach used was based on a first order kinetic model which depended on the initial heavy metal concentration in the wastewater and allowed for the evaluation of the … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractTamoxifen Drug Loading Solid Lipid Nanoparticles Prepared by Hot High Pressure Homogenization TechniquesNagi A. ALHaj, Rasedee Abdullah, Siddig Ibrahim, Ahmad BustamamAs drug delivery systems Nanoparticulate widely investigated because of many advantages such as smaller size, controlled drug release potential, targeting ability, enhancement of therapeutic efficacy and reduction of toxicity. So, Solid Lipid Nanoparticles have recently received considerable attention as alternative drug delivery carrier. In this study Solid Lipid Nanoparticles (SLNs) containing tamoxifen, nonsteroidal antiestrogens have been loaded and to be … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 3 · 30 Sep 2008 · 15,168 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Antidiabetic Efficacy of Combined Extracts from Two Continental Plants: Azadirachta indica (A. Juss) (Neem) and Vernonia amygdalina (Del.) (African Bitter Leaf)Patrick Ekong Ebong, Item Justin Atangwho, Eyong Ubana Eyong, Godwin Eneji EgbungPolyherbal therapy is said to be a current pharmacological principle having the advantage of producing maximum therapeutic efficacy with minimum side effects. We assessed the antidiabetic efficacy and hence the impact on biochemical indices of toxicity by a combination of extracts from neem and bitterleaf. Thirty rats, 25 diabetic and 5 non-diabetic rats, were used for the study. The diabetic … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 31 Aug 2008 · 14,400 accessesView PDFCite
Research ArticleOpen accessIn the abstractWaste Management: A Case Study of Ongoing Traditional Practices at East Calcutta WetlandShaon Raychaudhuri, Madhusmita Mishra, Poulomi Nandy, Ashoke R. ThakurCalcutta has a unique waste management system which uses the traditional non conventional practice for treating both the solid as well as soluble waste for its 12 million inhabitants . It not only detoxifies the waste but also generates resources for the existing society in form of employment as well as edibles like sufficient vegetable, fish as well as paddy … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,058 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudies On Bioemulsifier Production by Bacillus licheniformis PTCC 1595Gholamreza D. Noudeh, Mohammad H. Moshafi, Payam Khazaeli, Farideh AkefSurfactants are amphipathic molecules which reduce surface and interfacial tensions and widely used in pharmaceutical, cosmetic, food and petroleum industries. Biosurfactants are the structurally diverse group of surface-active molecules synthesized by microorganisms. There are several advantages for biosurfactants in contrast with chemical surfactants, such as lower toxicity; higher biodegradability; better environmental compatibility; higher foaming; high selectivity and specific activity at … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,282 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Soil Solution Chemicals after Tannery Effluents DisposalCélia A. Surita, Thomas Gloaguen, Célia R. Montes, Carlos T.S. DiasKnowledge about soil solution chemicals is important for assessing their mobility, availability, migration to groundwater and toxicity to plants. The objective of this study was to apply factor analysis to data obtained on soil solution chemicals during a one-year monitoring program in a controlled experiment with tannery effluents disposed on the soil surface, to extract information on their relationship and … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,772 accessesView PDFCite
Research ArticleOpen accessIn the abstractSorbitol-Induced Diabetic-Like Retinal Lesions in Rats: Microscopic StudyGaber A. RamadanThe present study investigated the sorbitol toxicity on the retinas of normal albino rats and founded by the light microscope that intra-peritoneal injection of Sorbitol (10-mg/kg-body weight per day) for 24 weeks produced similar diabetic like retinal lesions in these rats. The retinopathic effects of sorbitol injection affect retinal microvessels, pigment epithelium, neural retina and glial cells. Cytoplasmic vacuolation of … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 2 · 30 Jun 2007 · 7,630 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Value of Serologic Tests for Diagnosis and Follow up of Patients having BrucellosisNidia E. Lucero, Sandra M. Ayala, Gabriela I. Escobar, N R. JacobThough diagnosis of human brucellosis is accurate when the causal agent is isolated, this procedure is not always successful and the most of patients are diagnosed on the basis of rising titres of antibodies in serum. The classical tests used for detection of antibodies to S-Brucella sp., include Rose Bengal (RBT), buffered plate antigen (BPAT), serum agglutination (SAT), 2-mercapto-ethanol (2MET) … …American Journal of Infectious Diseases, Vol. 3, Issue 1 · 31 Mar 2007 · 7,446 accessesView PDFCite
