Hippocampal histamine receptors and conflictive exploration in the rat: studies using the elevated asymmetric plus-maze

Brazilian Journal of Medical and Biological Research, 1997
The possible role of histamine receptors in the hippocampal formation on the exploratory motivation and emotionality of the rat was studied. An elevated asymmetric plus-maze composed of 4 different arms (no walls, single high wall, high and low walls and

Accuracy of direct gradient sensing by cell-surface receptors [PDF]

arXiv, 2009
Chemotactic cells of eukaryotic organisms are able to accurately sense shallow chemical concentration gradients using cell-surface receptors. This sensing ability is remarkable as cells must be able to spatially resolve small fractional differences in the numbers of particles randomly arriving at cell-surface receptors by diffusion.

Antihistaminic, Anti-Inflammatory, and Antiallergic Properties of the Nonsedating Second-Generation Antihistamine Desloratadine: a Review of the Evidence

World Allergy Organization Journal, 2011
The allergy cascade presents widespread inflammatory and proinflammatory activation, robust cytokine and chemokine signaling, and heterogeneous immune and endothelial responses that lead ultimately to the manifestations of allergic reaction. Histamine, a

Serotonin as a Creativity Pump [PDF]

arXiv
The location of Western Civilization defined nations in Europe and in the United States within the largest global pollen environments on the planet is proposed as a key factor leading to their success. Environments with dense pollen concentrations will cause large up and down changes in serum histamine directly causing reductions and increases in brain

Combination of Leukotoriene Receptor Antagonist With Antihistamine Has an Additive Suppressive Effect on the Up-regulation of H1-Receptor mRNA in the Nasal Mucosa of Toluene 2,4-Diisocyanate-Sensitized Rat

Journal of Pharmacological Sciences, 2013
.: An attempt was made to clarify the additive suppressive effects of pranlukast, a cysteinyl leukotriene–receptor (LTR) antagonist, in combination with chlorpheniramine, an antihistamine, on the up-regulation of histamine H1–receptor (H1R) mRNA in ...

Chemical sensing by cell-surface chemoreceptor arrays: the roles of receptor cooperativity and adaptation [PDF]

arXiv, 2012
Most sensory cells use cross-membrane chemoreceptors to detect chemical signals in the environment. The biochemical properties and spatial organization of chemoreceptors play important roles in achieving and maintaining sensitivity and accuracy of chemical sensing.
