Strawberry fields forever?

چکیده
On the basis of copious preclinical data supporting the preventive efficacy of small fruits such as berries and grapes, Chen and colleagues conducted a randomized (noncomparative) phase II trial evaluating two doses of strawberry powder (60 g/d or 30 g/d for six months) to prevent esophageal cancer in China (reported in this issue of the journal, beginning on page 41); 60 g/d reduced the histologic grade of dysplastic lesions and reduced localized biomarkers, whereas 30 g/d was not effective. Fundamental questions remain such as the best formulation of strawberry powder, the active components associated with powder, and the actual mechanism of action, and standardized preparations will be required to permit the widespread use of strawberry powder with a predicable outcome. Clearly, however, this work is a good example of proof-of-principle and highlights the important role of diet, nutrition, and natural products in cancer prevention.

Selection for Pathogenicity to Strawberry in Populations of Colletotrichum gloeosporioides from Native Plants.
ABSTRACT Colletotrichum gloeosporioides causes a serious crown rot of strawberry and some isolates from native plants are pathogenic to strawberry. C. gloeosporioides from lesions on wild grape and oak were sampled at two sites adjacent to commercial strawberry fields in Florida and two distant sites. Random amplified polymorphic DNA (RAPD) marker data and restriction enzyme digests of amplifie...
متن کاملEffect of Crop Rotation on Meloidogyne spp. and Pratylenchus spp. Populations in Strawberry Fields in Taiwan.
Changes in population levels of Meloidogyne hapla, M. incognita, Pratylenchus coffeae, and P. penetrans were studied in 12 strawberry fields in the Dahu region of Taiwan. Ten potential rotation crops and two cultural practices were evaluated for their effect on nematode populations and influence on strawberry yield. Rotation with rice or taro and the cultural practice of flooding and bare fallo...
متن کاملGenetic and Pathogenic Analyses of Colletotrichum gloeosporioides Isolates from Strawberry and Noncultivated Hosts.
ABSTRACT Colletotrichum crown rot of strawberry in Florida is caused primarily by Colletotrichum gloeosporioides. To determine potential inoculum sources, isolates of Colletotrichum spp. from strawberry and various noncultivated plants growing in the areas adjacent to strawberry fields were collected from different sites. Species-specific internal transcribed spacer primers for C. gloeosporioid...
متن کامل"Candidatus Phlomobacter fragariae" Is the Prevalent Agent of Marginal Chlorosis of Strawberry in French Production Fields and Is Transmitted by the Planthopper Cixius wagneri (China).
ABSTRACT Marginal chlorosis has affected strawberry production in France for about 15 years. A phloem-restricted uncultured bacterium, "Candidatus Phlomobacter fragariae," is associated with the disease. A large-scale survey for marginal chlorosis in French strawberry production fields and nurseries by polymerase chain reaction amplification of "Ca. P. fragariae" 16S rDNA revealed that symptoms...
