We tested the prediction that higher polyandry levels should reduce the opportunity for pre-copulatory sexual selection on male mating success (the standardised variance in mating success,IS), while maintaining the opportunity for post-copulatory sexual selection on paternity share (the standardised varian...
Population-based behavioral surveillance is an essential public health activity for monitoring the health of adolescents. These surveys - often conducted b... Santelli,J Sandfort,T Orr - 《Archives of Pediatrics & Adolescent Medicine》 被引量: 127发表: 2008年 ...
The activity-regulated cytoskeletal (Arc) gene encodes a protein that is critical for memory consolidation. Arc is one of the most tightly regulated molecules known: neuronal activity controlsArcmRNA induction, trafficking and accumulation, and Arc protein production, localization and stability. Arc regu...
Introduction: Synovial sarcoma is high-grade malignancy and accounts for approximately 5-10% of the soft tissue sarcoma,which mainly occurs surrounding para-articular regions in adolescents and young adults. Surgical resection and combinationchemotherapy has resulted in about 60% five-year survival rate...

We found sex differences in activity level, but no evidence for sex differences in wall-following behaviour. We found no effects of mating in either sex, or of the presence of the sex peptide receptor in females, on wall following. Our results suggest that anxiety is not one of the ...
Lack of cyclin H expression is independent prognostic marker for poor outcome in diffuse large B cell lymphoma 177 Diffuse large-B-cell lymphoma (DLBCL) is the most common lymphoid malignancy in adults, accounting nearly 40% of all non-Hodgkin's lymphomas. Since combination chemotherapy cures only...
Briefly, serum-free medium from confluent monolayer of cells was collected and 5 ml were added to 4-aminophenylmercuric acetate (AMPA; 1 nmol/l) at 37 1C for 1 h to detect MMP-2 activity and at 37 1C for 2 h to detect MMP-9 activity. A 50 ml portion of the mixture was then ...
Other reviews of the efficacy of exergames for promoting physical activity in older adults also emphasize the need for more robust studies in order to determine the benefit of exergames [17–20]. Only seven of 56 studies in a recent review [19] compared the adherence to the exercises between...
Somatic cells generally do not maintain telomere sequences, and these cells become senescent in adults as telomeres shorten to a critical length. Some animals reproduce clonally and must therefore require adult somatic mechanisms for maintaining their chromosome ends. Here we study the telomere biology...
