Psychosocial character traits and coping skills were examined in 12 children with end-stage renal failure. Six of the children were maintained on in-center hemodialysis and 6 were treated with home peritoneal dialysis. All of the patients felt a lack of ability to control their lives. The incidence of anxiety, depression, and hostility did not appear to(More)
Groundnut ringspot virus (GRSV) and Tomato chlorotic spot virus (TCSV) are two emerging tospoviruses in Florida. In a survey of the southeastern United States, GRSV and TCSV were frequently detected in solanaceous crops and weeds with tospovirus-like symptoms in south Florida, and occurred sympatrically with Tomato spotted wilt virus (TSWV) in tomato and(More)
Phytophthora infestans has been a named pathogen for well over 150 years and yet it continues to "emerge", with thousands of articles published each year on it and the late blight disease that it causes. This review explores five attributes of this oomycete pathogen that maintain this constant attention. First, the historical tragedy associated with this(More)
Supplemented by a case illustration, findings from a study in Wales are reported for the first time from the application of two new instruments for measuring rewards and stresses among family caregivers. The paper takes as its starting point a critique of models of caregiving which emphasize instrumental and pathological dimensions. Findings suggest that(More)
Tomato (Solanum lycopersicum L.) is the second most highly consumed vegetable in the world after potato. Traits including physicochemical (lycopene, total titratable acid (TTA), total soluble solids (TSS) and vitamin C), morphological (fruit shape and size) and colors contribute to the overall fruit quality of tomato. The primary objective of the present(More)
This study investigated the impact of service learning on healthcare students, educators, and community partners in Ireland. Using a qualitative approach with focus groups and interviews, 38 participants' perceptions of the impact of service learning were recorded, transcribed, and analyzed. The findings in relation to the students reflected previous(More)
Twenty-one soluble proteins, five tRNAs, and three protein-nucleic acid complexes were studied in a systematic manner with regard to their crystallization behavior from polyethylene glycol and ammonium sulfate solutions in the presence of 0 to 1.5% beta-octyl glucoside. Our observations suggest that this neutral detergent does influence in a very positive(More)
Phytophthora capsici is an oomycete soil-borne plant pathogen that causes root, fruit and foliar disease on a variety of vegetables. The epidemiology and population structure varies depending on the region surveyed and our objective was to investigate survival and spread on farms on Long Island, New York using single nucleotide polymorphism (SNP) markers. A(More)
Basil (Ocimum spp.) is one of the most economically important and widely grown herbs in the world. Basil downy mildew, caused by Peronospora belbahrii, has become an important disease in sweet basil (O. basilicum) production worldwide in the past decade. Global sweet basil production is at significant risk to basil downy mildew because of the lack of(More)
Propidium iodide, an antitumor compound, was diffused into crystals of a complex between RNase A and deoxytetraadenylate (dpA)4). This complex has four deoxyoligomers bound per protein molecule. A difference Fourier analysis at 2.9 A showed that the principal binding site for the propidium in the crystals was a hydrophobic depression on the side of RNase(More)
