Background The hemostatic system is complex and evolves continuously since gestation and well into the adult years,in a process known as“developmental hemostasis.”Data sources A comprehensive review was performed after an extensive literature search on PubMed/MEDLINE concerning developmental hemostasis during the neonatal *** cross references were also *** Although part of a system,each component of the hemostatic system evolves differently,with many displaying both quantitative and qualitative age-related *** leads to drastic disparities between the coagulation system of neonates and both other children’s and adults’,while still maintaining a generally balanced and physiological *** motives behind this process remain to be fully elucidated but may be,at least in part,related to non-hemostatic *** Knowledge regarding“developmental hemostasis”is essential for everyone caring for newborns or even children in general and in this review,we describe each hemostatic system component’s neonatal characteristics and age-related progression as well as explore some of the possible physiological motives behind the process.

Laurel forests are quite relevant for biodiversity conservation and are among the island ecosystems most severely damaged by human *** the past,Canary laurel forests have been greatly altered by logging,livestock and *** remains of laurel forests are currently protected in the Canary Islands(Spain).However,we miss basic information needed for their restoration and adaptive management,such as tree longevity,growth potential and responsiveness to natural and anthropogenic *** dendrochronological methods,we studied how forest dynamic is related to land-use change and windstorms in two well-preserved laurel forests on Tenerife *** cores were collected from over 80 trees per stand at three stands per *** used ring-width series to estimate tree ages and calculate annual basal area increments(BAI),cumulative diameter increases,and changes indicative of released and suppressed *** tree species were found in all stands,with Laurus novocanariensis,Ilex canariensis and Morella faya being the most common *** some individuals were over 100 years old,61.8%-88.9% of the trees per stand established between 1940 and 1970,coinciding with a post-war period of land abandonment,rural exodus and the onset of a tourism *** trees have shown growth rates larger than 1 cm diameter per year and most species have had increasing BAI trends over the past *** growth releases occurred after windstorms at both sites,but the effects of windstorms were site-dependent,with the 1958 storm affecting mainly the eastern tip of the island(Anaga massif)and the 1991 storm the western tip(Teno massif).Given the great ability of laurel forest trees to establish after land use cessation and to increase growth after local disturbances such as windstorms,passive restoration may be sufficient to regenerate this habitat in currently degraded areas.
