Research ArticleOpen accessIn the abstractModulation of the GABAA Receptor by Srif in Rat ThalamusFatiha Chigr, Mariama El Ouahli, Ghizlane Er-Raoui et al.Somatostatin has been reported to modulate GABAA receptor complex in many brain structures. This study was conducted to investigate somatostatin modulation of the GABAA receptor binding in several rat diencephalic structures, focusing primarily on the thalamus, as this structure plays important roles. Animals were assigned to control conditions. Changes in specific binding of GABAA receptor as labelled with [35S]t-Butylbicyclophosphorothionate (TBPS) … …Neuroscience International, Vol. 3, Issue 2 · 14 Sep 2012 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Gaussian Process Regression Model for the Traveling Salesman ProblemWanatchapong Kongkaew, Juta PichitlamkenProblem statement: Traveling Salesman Problem (TSP) is a famous NP hard problem. Many approaches have been proposed up to date for solving TSP. We consider a TSP tour as a dependent variable and its corresponding distance as an independent variable. If a predictive function can be formulated from arbitrary sample tours, the optimal tour may be predicted from this function. … …Journal of Computer Science, Vol. 8, Issue 10 · 30 Aug 2012 · 7,373 accessesView PDFCite
Research ArticleOpen accessIn the abstractIs Color Perception of Packages Affected by Their In-aisle Position?Daniele Porcheddu, Maura Pugliatti, Antonio PinnaThe retail environment is characterized by numerous competing stimuli vying for the consumer’s attention. Products packages feature both verbal and nonverbal elements. Nonverbal stimuli, like package colors, seem to be particularly relevant for perception. Knowing whether there is preferential positioning of colored items on the shelves is fundamental for retailers. In addition, some colors may be better perceived than others. … …American Journal of Economics and Business Administration, Vol. 4, Issue 2 · 20 Apr 2012 · 8,757 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasures of Explained Variation and the Base-Rate Problem for Logistic RegressionDinesh Sharma, Dan McGee, B.M. Golam KibriaProblem statement: Logistic regression, perhaps the most frequently used regression model after the General Linear Model (GLM), is extensively used in the field of medical science to analyze prognostic factors in studies of dichotomous outcomes. Unlike the GLM, many different proposals have been made to measure the explained variation in logistic regression analysis. One of the limitations of these measures … …Current Research in Biostatistics, Vol. 2, Issue 1 · 25 Feb 2012 · 8,584 accessesView PDFCite
Research ArticleOpen accessIn the abstractThird Order of Automatic Restoration Scheme Offered in Fiber ToThe Home-Passive Optical Network through Customer Access Protection UnitMohammad Syuhaimi Ab-Rahman, Siti Asma Che Aziz, Kasmiran JumariProblem statement: This study highlight on restoration scheme proposed against failure in working line at the drop region for Fiber To The Home (FTTH) with a Passive Optical Network (PON). Whereas PON is a system that brings optical fiber cable and signals all or most of the way to the end user. In this study we highlighted the issue on … …Journal of Computer Science, Vol. 8, Issue 4 · 8 Feb 2012 · 6,320 accessesView PDFCite
Research ArticleOpen accessIn the abstractTemperature Effect on Uncooled Semiconductor Laser Diode to the Network Performance SystemMohammad Syuhaimi Ab-Rahman, Nurain Izzati ShuhaimiProblem statement: The characteristics of a laser diode are highly dependent on the temperature of the laser chip. Thus, the effect of temperature on the network performance of uncooled semiconductor laser diode are studied by simulating its equivalent electrical circuit, developed from the rate equations that governing optical components directly into an electrical simulation framework. Approach: The simulations are carried … …Journal of Computer Science, Vol. 8, Issue 4 · 8 Feb 2012 · 6,624 accessesView PDFCite
Research ArticleOpen accessIn the abstractErythropoietin-Like Effects of Dihydroartemisinin in Wistar Albino RatsUtoh-Nedosa Uchechukwu Anastasia, Nedosa Kenechi Stanislaus, Onyedibe Ikenna KennethArtemisinin drugs were active during the intra-erythrocytic stage of malaria parasite infection. The activity of artemisinin and synthetic endoperoxides was related to their interaction with heme. The electrophillic intermediate formed from artemisinin in the presence of heme alkylates the protein portion of hemoglobin preferentially to the heme portion. Problem statement: Since there might be an interaction between artemisinin and the … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 9 Dec 2011 · 7,787 accessesView PDFCite
Research ArticleOpen accessIn the abstractDihydroartemisinin-Stimulated Hyperplasia of Rat Lung Smooth MusclesUtoh-Nedosa Uchechukwu AnastasiaProblem statement: Dihydroartemisinin was shown to produce two types of inhibitory effects on the cardiac muscles of rats. It was also shown to stimulate haemopoiesis in the lungs, liver, spleen, intestine and kidney of rats. This study attempted to find out the nature of the effect of oral dihydroartemisinin on the lungs of Wistar albino rats. Approach: The effects of … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 8 Dec 2011 · 7,029 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtra-Bone Marrow Sites of Haemopoeisis: Dihydroartemisinin Effects in Wistar Albino RatsNedosa Uchechukwu Anastasia, Saleh Mohammed, Nedosa Kenechi Stanislaus et al.Problem statement: Iron is present in ferritin, the storage form of iron in the tissues; in the respiratory cytochrome enzymes; in hemoglobin of the blood and in the myoglobin of muscle Dihydroartemisinin (DHA) has been shown to interact with heme groups in vivo and in vitro. This study investigated the effects of 5 day and 7day oral dihydroartemisinin treatments on … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 2 Nov 2011 · 6,828 accessesView PDFCite
