1H-Imidazol-4(5H)-ones and thiazol-4(5H)-ones as emerging pronucleophiles in asymmetric catalysis
(Beilstein Institut, 2016-05-09)
Asymmetric catalysis represents a very powerful tool for the synthesis of enantiopure compounds. In this context the main focus has been directed not only to the search for new efficient chiral catalysts, but also to the ...
Leukocyte telomere length in patients with myotonic dystrophy type I: a pilot study
(Wiley, 2019-12)
Myotonic dystrophy type I (DM1) is an autosomal dominant disease of which clinical manifestations resemble premature aging. We evaluated the contribution of telomere length in pathogenesis in 361 DM1 patients (12 with ...

(ARKAT USA, Inc, 2012)
[EN] The reactivity of new three carbon synthon, generated in situ from the reaction of electrondeficient allenes with an appropriate phosphine as the catalyst, toward pronucleophilic reagents is described. Triphenylphos ...
Phosphorus substituted hydroxylamine and hydroxamic acid derivatives: synthesis and reactivity
(Arkat USA Inc, 2011)
[EN] This review summarizes several reports concerning the synthesis and synthetic applications of hydroxylamines derived from phosphines, phosphine oxides and phosphonates, and phosphorus substituted hydroxamic acid ...
Multiple table factor analysis applied to the higher education competences
(Purple Gate Publishing, 2012-04)
Due to the recent implantation of the Bologna
process, the definition of competences in Higher Education is an important matter that deserves special attention and requires
a detailed analysis. For that reason, we study ...
rhegf-Loaded Plga-Alginate Microspheres Enhance The Healing Of Full-Thickness Excisional Wounds In Diabetised Wistar Rats
(Elsevier, 2013)
[EN] Diabetic foot ulcers (DFUs) represent a major clinical challenge in the ageing
population. To address this problem, rhEGF-loaded Poly-Lactic-co-Glycolic-Acid (PLGA)-Alginate microspheres (MS) were prepared by a ...
Uncovering Ecosystem Service Bundles through Social Preferences
(Public Library of Science, 2012-06-18)
Ecosystem service assessments have increasingly been used to support environmental management policies, mainly based on biophysical and economic indicators. However, few studies have coped with the social-cultural dimension ...
Ancient DNA from Hunter-Gatherer and Farmer Groups from Northern Spain Supports a Random Dispersion Model for the Neolithic Expansion into Europe
(Public Library of Science, 2012-04-25)
Background/Principal Findings: The phenomenon of Neolithisation refers to the transition of prehistoric populations from a hunter-gatherer to an agro-pastoralist lifestyle. Traditionally, the spread of an agro-pastoralist ...
PPs without Disguises: Reply to Bruening
