Androgens have been shown to affect cognitive aspects of spatial memory. Testosterone which is the most important androgen, plays a role in the organization of behavior during development. Also, it has been shown that androgens cause sex related differences in learning and memory especially during neonatal period. In the current study, we assessed the effects of castration and testosterone ena...

Galois connection in category theory play an important role inestablish the relationships between different spatial structures. Inthis paper, we prove that there exist many interesting Galoisconnections between the category of Alexandroff $L$-fuzzytopological spaces, the category of reflexive $L$-fuzzyapproximation spaces and the category of Alexandroff $L$-fuzzyinterior (closure) spaces. This ...

introduction: it has been reported that oral morphine dependency facilitated formation of spatial learning and memory. in the present study the role of nmda receptors located in hippocampal ca1 area of morphine dependent rats was studied. methods: male rats were divided into 4 groups. two cannulae were stereotaxically implanted bilaterally into the hippocampal ca1 area. after 5 days recovery, a...

the population density and spatial distribution pattern of empoasca decipiens paoli were etermined in tehran area, iran, during 2004-2005 on four species of common bean phaseolus vulgaris (l.) var. talash, lima bean p. lunatus (l.) savi ex hassk. var. sadaf, rice bean p. calcaratus roxb. var. goli and cowpea vigna sinensis (l.) var. parastoo. the higher and lower mean population densities of e....

casimir forces of massive ferrnionic dirac fields are calculated for parallel plates geometry in spatial space with dimension d and imposing bag model boundary conditions. it is shown that in the range of ma>>l where m is mass of fields quanta and a is the separation distance of the plates, it is equal to massive bosonic fields casimir force for each degree of freedom. we argue this equality ex...

introduction: there are evidences showing the role of nitric oxide in the opiate reward properties. the role of nitric oxide signaling pathway as an intracellular mechanism on augmentation of long term potentiation in hippocampal ca1 area of rats is also confirmed. it has been also reported that oral morphine dependence facilitates formation of spatial learning and memory via activation of nmda...
