Youth who abuse alcohol or drugs, who are detained or incarcerated, or have mental health co-morbidity such as externalizing disorders, represent the most significant challenge to … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 7,281 accessesView PDFCite
Research ArticleOpen accessIn the abstractLoss of Morphine-induced Suppression of NK Cell activity and T-cell Functions in µ-Opioid Receptor Knockout MiceRichard J. Weber, Ricardo Gomez-Flores, Ichiro Sora, George R. UhlIn vivo administration of µ-opioid receptor selective agonists to various species is known to suppress lymphocyte, NK cell, and macrophage functions, in addition to mediate pain relief and euphoria. Using a mouse model in which the µ-opioid receptor gene was disrupted by targeted homologous recombination, we explored the involvement of this receptor in natural killer (NK) cell activity and T … …American Journal of Immunology, Vol. 2, Issue 2 · 30 Jun 2006 · 6,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Over-Voltages Produced by Lightning Strokes in the Power Transmission System in the Southern Region of Saudi ArabiaA. U. Al-Abdulaziz, S. M. Bashi, A. A. AlthubaitiThis study deals with the simulation of lightning strokes and their effects on power network in the southern region of Saudi Arabia. The network consists of main generating stations, substations and the power transmission lines. The transient performance of the system has been investigated using the EMTP (Electro Magnetic Transient Program). Some surges were introduced to the network as in … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,213 accessesView PDFCite
Research ArticleOpen accessIn the abstractCiprofloxacin Does Not Exert Nephrotoxicity in RatsAsli Baykal, Figen Sarigül, G Süleymanlar et al.Ciprofloxacin, a member of the fluoroquinolone class, is an antibiotic used as a treatment for infections including the Anthrax bacteria. Studies concerning the safety and efficacy of ciprofloxacin have been controversial with respect to nephrotoxicity. Using rats orally treated with ciprofloxacin (400mg/kg/d), the effects of this drug were analyzed measuring several indications of nephrotoxicity: β-NAG, creatinine, blood urea nitrogen, and … …American Journal of Infectious Diseases, Vol. 1, Issue 3 · 30 Sep 2005 · 7,440 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrochemical Characteristics of Some Purpurins in Aqueous and Nonaqueous SolutionsFarouk A. Rashwan, Hossnia S. Mohran, Ahmed A. El-SamahyThe Electrochemical Impedance Technique (EIS) and the Cyclic Voltammetric method (CV) were used to investigate the behavior of purpurin (P), Anthrapurpurin (AP) and Benzopurpurin (BP) in aqueous and in N, N-dimethylformamide (DMF) media. In the CV experiments, both the radical and the dianion of these substances were assumed to form of limited stability due to chemical protonation. In case of … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,743 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of UV-C on Drought Tolerance of Alfalfa (Medicago sativa) CallusAli Akbar Ehsanpour, Roya RazavizadehWater stress and unfavorable climate decrease the growth and development of plant globally. Medicago is a valuable plant as a source of food for animal, foliage and for medicine. Since, Iran is located in a dry area; consequently, the study of plant responses to water stress is important. In this research UV-C radiation was used to induce physiological and genetic … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,805 accessesView PDFCite
Research ArticleOpen accessIn the abstractAndrogen Receptor in Macrophages of Male Rat is Greater Than in FemaleKazem Ahmadi, Alan B. McCrudenThe presence and possible sex differences of androgen receptor in peritoneal macrophages was investigated using immunomagnetic beads. Macrophages were incubated with different concentrations of [3H]-5αDHT in the presence or absence of a 100 fold excess of unlabelled 5α-DHT. Labelled cells were separated from unbound steroid by immunomagnetic beads coated with anti-rat macrophage antibody. The binding identified in the rat macrophages … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,830 accessesView PDFCite
