Smell loss (hyposmia) is a common cognitive deficit perceived clinically as a nasal abnormality but, in reality, it is a deficit of complex biochemical detection and processing of externally generated chemical events. A major mechanism initiating hyposmia involves abnormalities of growth of human olfactory cells through altered growth factor stimulation of stem cell activity. While several growth factors are involved well known signaling substances generate and perpetuate this process; among these substances are cAMP and cGMP. We have hypothesized a role for cAMP in taste and olfaction as a growth factor necessary for stem cell maturation. We have thus measured cAMP and cGMP in parotid saliva of 19 normal subjects and 144 patients with hyposmia to evaluate roles for these signals in cognition. Results indicate that patients secrete significantly less cAMP (0.40+ / −0.03 pmol / mg protein (Mean+ / −SEM); patients; 0.67+ / −0.09, normals, p<0.005) and significantly less cGMP (0.072+ / −0.003, patients; 0.100+ / −0.007, normals, p<0.005) than do normals. While parotid gland secretions relate directly to taste bud growth factors many substances secreted in saliva are similar to those secreted in nasal mucus. The present results indicate aberrant signaling in saliva may serve both as a marker for hyposmia and as an indicator of a mechanism which interferes with olfactory system function.

Here, the Inventors show that chronic IL- 1 -induced H2A.X signaling, which mediated DNA DSB response, in hippocampal neurons is a critical driver of cognitive deficits in chronic low grade neuroinflammation. They show that mice chronically infected with the brain- persisting T. gondii parasite display deficits in spatial memory consolidation without general memory loss. Extensive mapping of the neuroinflammatory landscape, beyond a latent T. gondii infection elicited type 1-like neuroinflammation, display elevated production of IL-1α and IL-1β in the hippocampus. Using a mouse model to specifically delete the IL-1 receptor from excitatory neurons, they uncovered that neuronal IL-1 signaling is required for the spatial memory deficits caused by latent T. gondii infection. By singling out a chronic exposure to IL- ip they found that IL-1β signaling in neurons indeed impairs spatial memory. Moreover, they showed that chronic exposure to IL-1β increases DNA DSB levels in neurons, and that neuronal H2A.X-dependent DSB response mediates the IL-1β-induced memory deficits. Importantly, neuronal DSBs were also increased upon T. gondii infection and the deficit in hippocampus- dependent spatial memory caused by T. gondii infection was prevented by the abrogation of neuronal H2A.Xdependent signaling. These results highlight the instrumental role of cytokine- induced DSB-dependent signaling in spatial memory defects elicited by a chronic infectious neuroinflammatory process. Accordingly, the present invention relates to a method of treating a subject suffering from cognitive deficit comprising administering to said subject a therapeutically effective amount of an inhibitor of IL- 1 -induced H2A.X signaling.

The present invention relates to a memory optimization method. The method matches the similarity between a page and other pages according to JS files and CSS files loaded by the pages. When similar pages are matched, a memory sharing layer 1 is established. A memory creation method is used to count the memory byte blocks 1 created, and a threshold for creating the memory byte 1 is set. The created memory byte blocks 1 are stored in the sharing layer 1. An address mapping relationship between the shared memory and the virtual memory address 1 of the browser page is established.
