Research ArticleOpen accessIn the abstractBacterial Contamination and Resistance to Commonly Used Antimicrobials of Healthcare Workers' Mobile Phones in Teaching Hospitals, Kerman, IranGholamreza Sepehri, Nooshin Talebizadeh, Ali Mirzazadeh et al.Problem Statement: The contamination rates of Health Care Worker's (HCW) mobile phones and resistance to commonly used antimicrobials were evaluated in three teaching hospitals in Kerman, Iran. So, we examined 150 randomly selected HCWs in three teaching hospitals in Kerman, Iran, 2007. For each HCW a sterile swab moistened with sterile water was rotated over the surface of both sides … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Mini Review: Cholera Outbreak via ShellfishR. Suzita, A. S. Abdulamir, Fatimah Abu Bakar, R. SonProblem statement: Food borne illness occurs all over the world. Vibrio cholerae is the etiological agent of cholera which is spread by contaminated food, water or direct fecal contact with food handlers. There are also examples of sporadic outbreaks of illness attributed to raw products eaten unprocessed. Consequently, there was a widespread concern that food in international trade carries pathogenic … …American Journal of Infectious Diseases, Vol. 5, Issue 1 · 31 Mar 2009 · 8,315 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Higher Sludge Recycling Rate on Anaerobic Treatment of Palm Oil Mill Effluent in a Semi-Commercial Closed Digester for Renewable EnergyAlawi Sulaiman, Zainuri Busu, Meisam Tabatabaei et al.Problem statement: A 500 m3 semi-commercial closed anaerobic digester was constructed for Palm Oil Mill Effluent (POME) treatment and methane gas capture for renewable energy. During the start-up operation period, the Volatile Fatty Acids (VFA) accumulation could not be controlled and caused instability on the system. Approach: A settling tank was installed and sludge was recycled as to provide a … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 9,210 accessesView PDFCite
Research ArticleOpen accessIn the abstractVegetation Dynamics Depending on Ecological Particularities of Bozanta Mare (Maramures County-Romania) Tailing Pound: Case StudyMonica Marian, Leonard Mihaly Cozmuta, Camelia Varga et al.The present study followed an ecological demarche of reintegration in the scenary through revegetation of an anthropic ground, consisting in a waste pond formed from the flotation activity of non-ferrous ores. Problem statement: To support the formation of a compact vegetal layer, having anti-erosion and a restoration role, a preliminary study was required regarding the spontaneous settlement of different vegetal … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,361 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrobial Response to the Application of Amendments in a Contaminated Soil with Trace ElementsA. Branzini, M. S. Zubillaga, M. M. ZubillagaProblem Statement: The anthropogenic activities can cause adverse effects in soils, increasing in some situations trace elements contents, impacting negatively both the microbial biomass and activity. Among the practices used for the recovery of soil quality we can find the application of organic amendments or the product of their composting. These can adsorb trace elements decreasing their availability and increasing … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of Major Cultivable Aerobic Bacteria in the Oral Cavity of Malaysian SubjectsKoshy Philip, Wuen Yew Teoh, Sekaran Muniandy, Hashim YaakobCulture dependent and culture independent methods have shown that about 600 species of bacteria inhabit the human oral cavity. While some oral microorganisms have a direct link to dental caries, periodontal disease and halitosis, opportunistic pathogens may be responsible for systemic diseases such as bacterial endocarditis, aspiration pneumonia, osteomyelitis in children, preterm low birth weight, coronary heart disease and cerebral … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 7,990 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review on Some Organic Acids Additives as Shelf Life Extenders of Fresh Beef CutsMohamed B. Jamilah, K.A. Abbas, R. Abdul RahmanThis study was aiming to present some approaches by which the shelf life of fresh beef cuts was extended. These approaches were based on using organic acids. Therefore the work was started with highlighting the deterioration of some quality attributes due to spoilage and pathogenic microorganisms. These attributes included colour, flavour and lipid oxidation changes. In a given holding temperature, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,736 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 abstractStandard Versus Specific Therapy for Chronic Osteomyelitis TreatmentAngela Ingianni, Giorgio Lampis, Samuela Laconi et al.58 patients with chronic osteomyelitis were treated either with a standard therapy or with a specific targeted therapy based on the antibiogram assay. Standard therapy was performed by a 15-day course of a parenteral cephalosporin (usually ceftriaxone) in combination with an aminoglycoside (e.g. netilmicin), followed by oral therapy with a fluoroquinolone (generally ciprofloxacin) for 1 to 3 months; specific therapy … …American Journal of Infectious Diseases, Vol. 3, Issue 3 · 30 Sep 2007 · 6,874 accessesView PDFCite
