the considerable role of ziziphus spina christi in preserving water and soil and its resistance to heat and drought, the necessity of planting this species for afforestation and restoration of their habitats and urban green space is obvious. the aim of this study was to determine the best irrigation and seedbed treatments before planting for ziziphus spina christi seedling production. this stud...

The objective of this study was to determine whether myogenic tone in the cerebral circulation can be modified by agents that interact with protein kinase C (PKC), a modulator of intracellular calcium sensitivity. Pial arteries (194 +/- 8 microns at 125 mm Hg) were isolated from Wistar-Kyoto rats and mounted on glass microcannulas in a specialized arteriograph. Simultaneous recordings of transm...

Abstract • Key message Errors in forest stand attributes can lead to sub-optimal management prescriptions concerning the set objectives. When objective is net present value, errors mean diameter result greater losses than similar basal area, and underestimation overestimation. Context inventory data cause inoptimality objectives management. Losses occur when treated with that are optimal for er...

In this study, three phenolic compounds were isolated from the seeds of Zizyphus spina-christi for the first time. The compounds were identified by means of 1 H-NMR-, UV and GC-MS as p-hydroxybenzoic acid, kaempferol, quercetin-3-O--L-rhamnosyl--D-glucopyranoside (rutin).
