A METHODOLOGICAL APPROACH FOR THE NON-MONETARY VALUATION OF ECOSYSTEM SERVICES IN THREE COMMUNITIES OF THE COLOMBIAN AMAZON

A methodological approach for the non-monetary valuation of ecosystem services in three communities of the Colombian Amazon

To conduct a non-monetary valuation of ecosystem services, this study explored combining data on the use of ecosystem resources with measuring the effort expended on agricultural activities in three communities of the lower Caqueta, Colombian Amazon.By measuring the energy expended by people during their principal subsistence activities, Impact Dri

Intracranial ependymoma: long-term results in a series of 21 patients treated with stereotactic (125)iodine brachytherapy.

BACKGROUND: We evaluated the long-term outcome in patients harboring intracranial ependymomas treated with interstitial brachytherapy (IBT).METHODS: Twenty-one patients (M/F = 9/12; median age: 29 years; range: 8-70 years), diagnosed with intracranial ependymoma (1 WHO I, 11 WHO II, 9 WHO III) were treated with IBT using stereotactically implanted

In vitro generation of neuromesodermal progenitors reveals distinct roles for wnt signalling in the specification of spinal cord and paraxial mesoderm identity.

Cells of the spinal cord and somites arise from shared, dual-fated precursors, located towards the posterior of the elongating embryo.Here we show that these neuromesodermal progenitors (NMPs) can readily be generated in vitro from mouse and human pluripotent stem cells by activating Wnt and Fgf signalling, timed to emulate in vivo development.Simi
