Nitrogen (N) transfer from N-fixing legumes via vesicular-arbuscular mycorrhizal (VAM) fungi to associated non-fixing plants has been demonstrated in greenhouse experiments. To date, this transfer has been shown only where mineral N is applied shortly before harvest, and hence is readily available. We have yet to demonstrate VAM-mediated N transfer where(More)
‘... I have a client who is now 22 weeks pregnant whose appeal for asylum was rejected last year, I understand on grounds of being 2 days overdue in her application. She is very vulnerable, has no partner, speaks little English, has no means of income, and is living in very poor conditions in a ‘flat’ above a derelict factory in Hackney. The premises has no(More)
Pesticide Action Network, United Farmworkers of America, and California Rural Legal Assistance Foundation analyzed California government data on agricultural poisonings and enforcement of worker safety standards. Nearly 500 pesticide poisonings were reported for California farmworkers every year from 1997 to 2000. The actual number of pesticide-related(More)
Phosphatidic acid and its hydrolysis product, diacylglycerol, play potentially vital roles as extracellular messengers in numerous cellular systems and may play a key role in regulating hematopoiesis. In this study, we describe an ecto-phosphatidic acid phosphohydrolase that potentially regulates cellular responses to phosphatidic acid on bone marrow(More)
Part A: " Organic foods are not healthier than non-organic foods/Organic foods are unhealthy " Misconception Number 1: Pesticide residues in conventional foods are always within safe levels. Summary of Counter-Arguments-A significant percentage of conventional food products contain pesticide residues in excess of legally-defined, maximum, authorized residue(More)
BACKGROUND AIMS Peripheral blood progenitor cell (PBPC) products are often transported at high cell concentrations (>200x10(9)/L) over long distances, requiring >36 h transport time. METHODS Fresh PBPC samples from 12 healthy donors were studied with various viability assays regarding the effects of temperature, cell concentration and duration of storage.(More)
Pesticide Action Network North America reviewed a report issued October 12, 2005, by Florida’s Collier County Health Department and a report issued October 2 by the Florida Department of Agriculture and Consumer Services regarding birth defects and possible links to pesticides. PAN believes that the reports’ dismissal of a possible link between pesticide(More)
The effects of the composition of PBPC grafts from matched related donors (MRDs) and matched unrelated donors (MUDs) have not been compared. In a single-center study, the compositions of 55 MRD PBPC grafts and 33 MUD grafts were studied for their effect on the rate of engraftment in patients who had evidence of donor cell engraftment on day +28. The MUD(More)
BACKGROUND AIMS Peripheral blood progenitor cell (PBPC) products are often transported at high cell concentrations (>200 × 10⁹/L) over long distances, requiring >36 h transport time. METHODS Fresh PBPC samples from eight healthy donors were studied with two viability assays for effects of temperature outside the transport container (ambient temperature).(More)
