Serum alkaline phosphatase (AP) was estimated in a total of 786 (418 males and 386 females) apparently healthy people aged between 1-75 years selected randomly from a sample of the Karachi population. Reference ranges for AP level were obtained for the males and females stratified into ten successive age groups. The study population was also divided into two main age groups, a paediatric aged b...

The commonly used linear k-ε turbulence model is shown to be incapable of accurate prediction of turbulent flows, where non-isotropy is dominant. Two examples of non-isotropic flows, which have a wide range of applications in marine waters, are saline water flow and the stratified flows due to temperature gradients. These relate to stratification and consequently, variation of density through...

Phytoplankton vertical and diel dynamics in a small shallow lake (Lake Monte Alegre, Ribeirão Preto, state of São Paulo) were investigated in two climatological periods: July 2001 (cool-dry season) and March 2002 (warm-rainy season). Monte Alegre is a eutrophic reservoir, with a warm polymictic discontinuous circulation pattern. The lake was thermally stratified in both periods, although dissol...

For fibred boundary and fibred cusp metrics, Hausel, Hunsicker, and Mazzeo identified the space of L harmonic forms of fixed degree with the images of maps between intersection cohomology groups of an associated stratified space obtained by collapsing the fibres of the fibration at infinity onto its base. In the present paper, we obtain a generalization of this result to situations where, rathe...

The use of transthyretin (TTR, prealbumin) as a marker malnutrition and the definition associated cut-offs are matter debate. In order to clarify this issue, we performed retrospective study then prospective validation one. first study, data from 23,617 consecutive patients our University hospital were analysed. Using 0.11 0.05 g/L cut-off values defined by French Health Authority, only 3.13% 0...

BACKGROUND The activity of paraoxonase 1 (PON1), an antioxidant enzyme whose polymorphisms have been associated with cancer risk, may be associated with metals exposure. OBJECTIVE To evaluate PON1 activity in relation to cadmium, lead, and mercury levels in healthy, premenopausal women. METHODS Women from upstate New York were followed for ≥ two menstrual cycles. Repeated measures linear mi...
