For multiple axons from one neuron to extend in different directions to unique targets, the growth cones of each axon must have distinct responses to guidance cues. However, the mechanisms by which separate axon branches are guided along different pathways are mainly unknown. Zebrafish Rohon-Beard (R-B) sensory neurons extend central axon branches in the spinal cord and peripheral axons to the ...

the objective of the article is to investigate the variability in growth and wood properties of the willow clones. the growth and wood traits of four year old 21 clones willow clones were investigated. analysis of variance showed that willow clones differed significantly for all the studied growth and wood traits. among the growth parameters the maximum heritability value was shown by height wh...

Materials with the propensity to undergo irreversible deformation display an increasing resistance progressive crack advance, i.e., stable growth. A one-parameter description of growth by a fracture toughness vs. advance (resistance) curve is possible under specific conditions. Here, experimental observations are reported (i) demonstrate that enhancement due in hysteretic materials may be “reve...

Reduced seedling growth is a consequence of seed deterioration. The heterotrophic seedling growth can be considered as the product of three components: (1) initial seed weight, (2) the fraction of seed reserves which are mobilized, and (3) the conversion efficiency of mobilized seed reserves to seedling tissues. It is not clear which of these component (s) is affected by seed deterioration. To ...

BACKGROUND Advance care planning (ACP) promotes care consistent with patient wishes. Medical education should teach how to initiate value-based ACP conversations. OBJECTIVE To develop and evaluate an ACP educational session to teach medical students a value-based ACP process and to encourage students to take personal ACP action steps. DESIGN Groups of third-year medical students participate...
