A Proof and derivation of manifold-related ingredients The concrete computations of the optimization-related ingredients presented in the paper are discussed below. The total space is M := St(r1, n1) × St(r2, n2) × St(r3, n3) × Rr1×r2×r3 . Each element x ∈ M has the matrix representation (U1,U2,U3,G). Invariance of Tucker decomposition under the transformation (U1,U2,U3,G) 7→ (U1O1,U2O2,U3O3,G×...

The aim of this work is to predict relative biological effectiveness (RBE) for protons and clinically relevant heavier ions, by using a simplified semi-empirical process based on rational expectations and published experimental results using different ion species. The model input parameters are: Z (effective nuclear charge) and radiosensitivity parameters αL and βL of the control low linear ene...

It is essential to have a thorough knowledge of the bioavailability and metabolism of dietary flavonols to understand their role in disease prevention. Lightly fried onions containing 275 micromol flavonols, principally quercetin-4'-glucoside and quercetin-3,4'-diglucoside, were fed to healthy human volunteers and plasma and urine were collected over a 24 h period. Samples were analysed by HPLC...

Our previous study showed that quercetin enhances the anticancer effect of trichostatin A (TSA) in xenograft mice given quercetin intraperitoneally (10 mg/kg, 3 times/week). Herein, we investigate whether quercetin administered orally exerts such an effect and prevents the cytotoxic side effects of TSA. We found that quercetin given orally (20 and 100 mg/kg, 3 times/week) failed to enhance the ...

Quercetin is a dietary polyphenolic compound with potentially beneficial effects on health. Claims that quercetin has biological effects are based mainly on in vitro studies with quercetin aglycone. However, quercetin is rapidly metabolized, and we have little knowledge of its availability to tissues. To assess the long-term tissue distribution of quercetin, 2 groups of rats were given a 0.1 or...
