Lead (Pb) released from anthropogenic sources and stored in environmental repositories can be a potential source for secondary pollution. Here we develop a novel approach for tracking Pb from atmospheric deposition and other sources in the environment using fallout (210)Pb as a tracer, and apply the method to samples collected from Richmond Park, London, the UK. The mean ratio of (210)Pb to tot...

Human placental blood (PB) is increasingly used as a source of hematopoietic stem cells for transplantation. Since the first successful transplant in 1988, more than 50 pediatric patients have been engrafted by means of PB collected at the birth of full-term newborns.’ and large PB banking programs are arising both in the United States and in Europe.’ In this regard, concern has been raised abo...

BACKGROUND AND PURPOSE In a murine model of stroke, we identified a population of very small embryonic-like (VSEL) stem cells (SCs) in adult murine bone marrow that could be mobilized into peripheral blood (PB). This raised the question of whether a similar population of cells is mobilized in human stroke patients. METHODS We evaluated a number of cells that corresponded to VSEL SCs in the PB...

Spleen cell populations depleted of both B and T lymphocytes produce interleukin 4 (IL-4) in response to stimulation with immunoglobulins bound to the surface of culture dishes. In the presence of interleukin 3 (IL-3), plate-bound (PB) IgE and PB-IgG1, IgG2a, and IgG2b are excellent stimulants, whereas PB-IgA and PB-IgM fail to stimulate IL-4 production. In the absence of IL-3, PB-IgE stimulate...

The role of phytochelatins (PC(n), metal-binding oligopeptides with the general structure (γGlu-Cys)(n)-Gly (n = 2-11) in metal detoxification is assumed to be based on immobilization of metals, which prevents binding of metals to important biomolecules. Although induction of phytochelatin synthesis has often been observed in algae upon exposure to metals, direct evidence for binding of the ind...

Most popular vegetables and fruits and their corresponding soil from the sub-urban industrial area of Bangladesh were collected and the concentration of carcinogenic (Pb, As, and Cd) and non-carcinogenic (Fe, Co, V, Cu, Cr, Zn, Mn, and Ni) heavy metals was determined. Health risk was evaluated by estimating daily heavy metal intake and computing cancer and non-cancer risks (ILCR and THQ) using ...
