We predicted that adopting a performance-approach vs. performance-avoidance goal would lead to physiological responses characteristic of psychological states of challenge vs. threat appraisals, respectively. Furthermore, we predicted that these states would mediate the effects of goals on performance. Twenty-seven undergraduate females performed a task described as identifying either exceptiona...

The 2006 US Pandemic and All-Hazards Preparedness Act gave the Department of Health and Human Services (HHS) new authority to fund the development and procurement of medical countermeasures against chemical, biological, radiological, and nuclear (CBRN) threats. The legislation builds on the authority the HHS gained in 2004 under Project BioShield, which established a fund to procure medical cou...

Azathioprine, cyclophosphamide, and gold have been compared under double-blind conditions in the treatment of relatively early rheumatoid arthritis. Over 18 months the two "immunosuppressive" agents produced clinical improvement comparable to that achieved with gold, and they also facilitated a reduction in the dosage of corticosteroids and retarded radiological joint deterioration. Drug manage...

The harmful effects of ionising radiation are widely acknowledged. It has been reported that young children, particularly girls, have a higher sensitivity to radiation than adults. However, the exact detrimental effects of radiation, particularly at the low doses used in routine diagnostic radiography, are unknown and the subject of much controversy. Computed tomography (CT) accounts for about ...

Catastrophic chemical or radiological events can cause thousands of casualties. Such disasters require triage procedures to identify the development of health consequences requiring medical intervention. Our objective is to analyze recent advancements in biotechnology for triage in mass emergency situations. In addition to identifying persons "at risk" of developing health problems, these techn...

Following the increasing demand of coal for power generation, activity concentrations of primordial radionuclides were determined in Nigerian coal using the gamma spectrometric technique with the aim of evaluating the radiological implications of coal utilization and exploitation in the country. Mean activity concentrations of 226Ra, 232Th, and 40K were 8.18±0.3, 6.97±0.3, and 27.38±0.8 Bq kg-1...
