OBJECTIVE to examine if those adolescents who dislike physical education classes get better results on academic and cognitive performance than their peers. METHODS participants included 4 226 adolescents from the AVENA, AFINOS and UP&DOWN studies. Physical education enjoyment was assessed with a 7-point Likert scale. Cognitive performance in the AVENA study was assessed using the Spanish vers...

Allophlebia is proposed as a new genus in Meruliaceae based on morphological characters and molecular data. The genus, so far monotypic, typified by Peniophora ludoviciana the combination A. proposed. type species characterized resupinate basidioma, monomitic hyphal system with clamp connections, two types of cystidia (leptocystidia metuloids), clavate basidia, hyaline, thin-walled ellipsoid ba...

Sequence databases could be efficiently exploited for development of DNA markers if it were known which gene regions reveal the most polymorphism when amplified by PCR. We developed PCR primer pairs that target specific regions of previously sequenced genes from Avena and Zea species. Primers were targeted to amplify 40 introns, 24 exons, and 23 promoter regions within 54 maize genes. We survey...
