Rooibos tea flavonoids increase mineral content in human osteoblast-like cells

Some cross-sectional and prospective studies have demonstrated a positive correlation between habitual tea consumption and bone mineral density in post-menopausal women. Rooibos tea contains no caffeine and is a rich source of flavonoids such as rutin, orientin, hyperoside and luteolin. These flavonoids have similar structures to estradiol, and therefore may act as estrogen mimics to promote favourable outcomes in bone. The overall objective of this research was to identify flavonoids that could enhance mineral content in human osteoblast Saos2 cells. Mineral was quantified by alizarin red staining and characterized by quantifying alkaline phosphatase (ALP) activity, cell mitochondria activity and toxicity, in addition to changes in regulatory markers of osteoblastic activity. Rutin (≥50μM), hyperoside (≥5.0μM), orientin (0.1μM-1.0μM, 15μM-100μM) and luteolin (5.0μM) enhanced mineral content. This was in part due to elevated ALP and mitochondrial activity, and lower toxicity, pro-inflammatory cytokines, and Wnt inhibitors.

On the anharmonic, multi-phonon, Debye-Waller contributions to the phonon-limited resistivity of metals : applications to Na and K

The anharmonic, multi-phonon (MP), and Oebye-Waller factor (OW) contributions to the phonon limited resistivity (;0) of metals derived by Shukla and Muller (1979) by the doubletime temperature dependent Green function method have been numerically evaluated for Na and K in the high temperature limit. The anharmonic contributions arise from the cubic and quartic shift of phonons (CS, QS), and phonon width (W) and the interference term (1). The QS, MP and OW contributions to I' are also derived by the matrix element method and the results are in agreement with those of Shukla and Muller (1979). In the high temperature limit, the contributions to;O from each of the above mentioned terms are of the type BT2 For numerical calculations suitable expressions are derived for the anharmonic contributions to ~ in terms of the third and fourth rank tensors obtained by the Ewald procedure. The numerical calculation of the contributions to;O from the OW, MP term and the QS have been done exactly and from the CS, Wand I terms only approximately in the partial and total Einstein approximations (PEA, TEA), using a first principle approach (Shukla and Taylor (1976)). The results obtained indicate that there is a strong pairwise cancellation between the: OW and MP terms, the QS and CS and the Wand I terms. The sum total of these contributions to;O for Na and K amounts to 4 to 11% and 2 to 7%, respectively, in the PEA while in the TEA they amount to 3 to 7% and 1 to 4%, respectively, in the temperature range.

Colin Duquemin fonds, 1935, 1968-2001, n.d.

Colin Duquemin was born in 1932 in Guernsey, British Channel Islands, and came to Canada as a young adult. He attended McMaster University (B.A.), the University of Toronto (B.Ed.), the State University of New York at Buffalo (M.A.) and the University of London, London, England (M.Sc.). He began his career as a tea taster and tea buyer in Colombo, Ceylon (Sri Lanka), but later became a teacher. He spent most of his teaching career as a manager of the St. Johns Outdoor Studies Centre, north of Fonthill, Ontario, developing environmentally related programmes for elementary and secondary school students. He was also active in many local organizations, serving as Associate Director of the St. Catharines Grape and Wine Festival Board, Chairman of the St. Catharines Historical Museum Board, President of the Niagara Military Institute and President of the Canadian Canal Society. In addition to the numerous curriculum materials he authored, Colin wrote the Driver’s Guide Series, highlighting the many points of interest in the Niagara region, including the Welland Canal, battlefields of the War of 1812, and the Niagara Parkway. He also wrote A Guide to the Grand River Canal (1980) with Daniel Glenney, The Fur Trade in Rupert’s Land: Opening up the Canadian Northwest (1992), Stick to the Guns! A short history of the 10th field battery, Royal Regiment of Canadian Artillery (1996), Niagara Rebels: the Niagara Frontier Incidents in the Upper Canada Rebellion, 1837-1838 ( 2001), and edited and contributed to A Lodge of Friendship: the History of Niagara Lodge, No. 2, A.F. & A.M, Niagara-on-the-Lake, Ontario, Canada, 1792-1992 (1991). He died in December 2012.
