Examination of the influence of cedar fragrance on cognitive function and behavioral and psychological symptoms of dementia in Alzheimer type dementia.

We examined whether symptoms of dementia are improved by olfactory nerve stimulation in Alzheimer type dementia patients. First, a stick-type olfactory identification ability test was performed in patients with Alzheimer type dementia, to select patients without olfactory dysfunctions. Then, these patients were randomly assigned into the intervention (n = 19) and the control groups (n = 17).

Factors affecting levels of ferulic acid, ethyl ferulate and taste-active pyroglutamyl peptides in sake.

Factors affecting ferulic acid, ethyl ferulate and taste-active pyroglutamyl (pGlu) peptides levels in sake were analyzed using small-scale sake brewing tests on eighteen rice samples with differing cultivar variety, cropped year and area, and polishing rate. Ferulic acid concentration in sake was highly positively correlated with its content in rice (r = 0.782**, double asterisk indicates 1% significance level), feruloylesterase (FE) activity (r = 0.

Quantum chemical molecular dynamics simulations of dynamic fullerene self-assembly in benzene combustion.

Using density-functional tight-binding (DFTB)-based quantum chemical molecular dynamics at 2500 and 3000 K, we have performed simulations of benzene combustion by gradually reducing the hydrogen to carbon (H/C) ratio. The accuracy of DFTB for these simulations was found to be on the order of 7-9 kcal/mol when compared to higher-level B3LYP and G3-like quantum chemical methods in extensive benchmark calculations. Ninety direct-dynamics trajectories were run for up to 225 ps simulation time, during which hydrocarbon cluster size, curvature, and C(x)H(y) composition, carbon hybridization type, and ring count statistics were recorded.
