The use of supramolecular architectures to control the spatially dependent spin exchange (spin communication) between two covalently linked radical centers (biradical) has been explored. Cucurbit[8]uril, through supramolecular steric effect, completely suppresses spin exchange between two adjacent radical centers in a biradical.

The synthesis of a supramolecular double hydrophilic peptide-conjugated polymer held together by cucurbit[8]uril (CB[8]) ternary complexation and its subsequent temperature triggered self-assembly into vesicles are described. Basic fibroblast growth factor can be easily loaded into the vesicles under benign conditions and their bioactivities can be preserved without the need for excipients such...

OBJECTIVE Vegetable intake among children is well below recommended levels. We assessed whether food neophobia and pickiness contribute to low vegetable intake in school-aged girls and if there are distinct predictors for neophobia and pickiness. Children with food neophobia are reluctant to eat new foods whereas picky children resist eating many familiar foods. Design/subjects Participants wer...

Background. The two strongest barriers to increasing children’s dietary variety and consumption of fruit and vegetables are food neophobia and pickiness, assumed to be the main kinds of food rejection in children. Accordingly, psychometric tools that provide a clear assessment of food neophobia and pickiness are greatly

Sicana odorifera is reported for the first time as a natural host of South American cucurbit fruit fly, Anastrepha grandis . This paper presents information on this new and discusses distribution A. its hosts in Brazil. In addition, Cucurbita moschata recorded state Paraná.

background: given the importance of vegetables in the food pyramid, their safety is very important from view point of public health. vegetable contamination by heavy metals can lead to bioaccumulation of these toxic and disease-causing elements in the body of consumers. therefore, in this study, the concentration of some heavy metals, including lead (pb), cadmium (cd), zinc (zn) and copper (cu)...

we investigated the microbiological quality of raw vegetables in mashhad, iran. in order to document the incidence of indicator and pathogenic microorganisms in this area. ninety eghit raw vegetable samples collected during 7 months were analyzed. all samples were examined for the presence of aerobic mesophilic bacteria, coliforms, enterobacteriaceae, escherichia coli, escherichia coli o157:h7,...

Cucurbit chlorotic yellows virus (CCYV) and cucurbit yellow stunting disorder (CYSDV) are two closely related criniviruses that often coinfect cucurbits associated with disease. Both viruses distributed worldwide transmitted in a semipersistent manner by the whitefly vectors Bemisia tabaci MED or MEAM1. The major goal of this study was to provide insight into interaction CCYV CYSDV cucumber eff...
