Functional studies of the dorsolateral prefrontal cortex and the inferior parietal lobe of the rhesus monkey have implicated the former in spatial mnemonic function and the latter in visuospatial processing. We used the 14C-2-deoxyglucose (2DG) method to assess the contribution of these cortical regions to the cognitive performance of monkeys on working memory tasks. In these experiments, one g...

For two vertices X,Y ∈ V (G), a cycle is called a geodesic cycle with X and Y if a shortest path joining X and Y lies on the cycle. A graph G is called to be geodesic k-pancyclic if any two vertices X,Y on G have such geodesic cycle of length l that 2dG(X,Y ) + k ≤ l ≤ |V (G)|. In this paper, we show that the n-dimensional Möbius cube MQn is geodesic 2-pancyclic for n ≥ 3. This result is optima...

The parthenogenetic lizard Cnemidophorus uniparens alternates in the display of male-like and female-like sexual behavior, providing a unique opportunity for determining the neuronal circuits subserving gender-typical sexual behavior within a single sex. Here we report a 6-fold greater [14C]2-fluoro-2-deoxyglucose uptake in the medial preoptic area of C. uniparens displaying male-like behavior ...

Ionic liquids are a very important class of compounds due to their remarkable properties and wide range applications. On the other hand, capillary electrophoresis is also gaining importance in separation science because its fast speed inexpensive nature. The use ionic continuously. present review article describes applications electrophoresis. This general aspects electrophoresis, optimization ...

The challenge associated with the use of synovial fluid for osteoarthritic proteome studies is optimization step, which involves depletion high abundant proteins from samples. objective this study was to develop a cost efficient and effective method remove albumin canine studies. Pooled samples were obtained clinically healthy dogs (n=5), no radiographic features osteoarthritis. acetone precipi...
