In 1988, the National Vietnam Veterans Readjustment Study (NVVRS) of a representative sample of 1200 veterans estimated that 30.9% had developed posttraumatic stress disorder (PTSD) during their lifetimes and that 15.2% were currently suffering from PTSD. The study also found a strong dose-response relationship: As retrospective reports of combat exposure(More)
In 1988, the National Vietnam Veterans Readjustment Study (NVVRS) reported 30.9% lifetime and 15.2% current rates of posttraumatic stress disorder (PTSD), and a strong dose/response relationship with retrospective reports of combat exposure. Skeptics argued that recall bias and other flaws inflated the results. Using a new record-based exposure measure and(More)
The induced synthesis of galactokinase and the repressing effects of glucose on this synthesis have been investigated in whole yeast cells rendered permeable by treatment with dimethyl sulfoxide. It was found that the induction response of uninduced cells to galactose is clearly dependent on the nature of the carbon source upon which the culture was grown(More)
The September 11, 2001 (9/11), terrorist attacks were unprecedented in their magnitude and aftermath. In the wake of the attacks, researchers reported a wide range of mental and physical health outcomes, with posttraumatic stress disorder (PTSD) the one most commonly studied. In this review, we aim to assess the evidence about PTSD among highly exposed(More)
In order to determine whether hand carriage of aerobic Gram-negative rods is continuous we used the glove-handwash technique to sample the hands of two groups (four each) of health care workers with normal hands (surgical intensive care unit, medical ward) and one group (four) with hand dermatitis (HD) and a group (five) of control subjects -- secretaries(More)
A quantitative culture technique (hand washed in a glove containing broth for 30 s) was used to determine the frequency of hand carriage of aerobic Gram-negative rods by various groups of health care workers and 104 control subjects. Overall, 31% of health care workers carried aerobic Gram-negative rods on their hands compared to 59% of control subjects (P(More)
By use of a selective galactose agar medium containing ethidium bromide, a population analysis of the deinduction kinetics of yeast galactose long-term adaptation mutants (gal 3) has been done. It was first determined that the gal 3 mutation is specific to the yeast galactose system and that induced cultures of gal 3 strains are capable of growth on(More)
By use of a selective medium containing ethidium bromide, population analyses of yeast galactose long-term adaptation mutants (gal3) in the process of deadaptation in the absence of galactose have been performed. The analysis of diploid strains homozygous for the gal3 locus but heterozygous for different combinations of the other mutant galactose loci,(More)
Intra-arterial chemotherapy has been used preoperatively in treating patients with carcinoma of the stomach. The chemotherapy was given continuously for about one month with gastrectomy planned for three to four weeks after completion of chemotherapy. The agents used were 5-fluorouracil, Adriamycin (doxorubicin hydrochloride) and mitomycin C. The objective(More)
The diagnosis, Posttraumatic Stress Disorder, was introduced in 1980 amidst debate about the psychiatric toll of the Vietnam War. There is controversy, however, about its central assumption that potentially traumatic stressors are more important than personal vulnerability in causing the disorder. We tested this assumption with data from a rigorously(More)
