(Marcel Dekker Inc., 1999)A novel route to 5,7-dimethoxy-6-hydroxyflavone is described, involving the cyclization of an intermediate phosphorane as the key step.
-
(2012)BACKGROUND AND PURPOSE The μ-conopeptide family is defined by its ability to block voltage-gated sodium channels (VGSCs), a property that can be used for the development of myorelaxants and analgesics. We characterized the ...
-
(Elsevier, 2020)The atmospheric deposition of polycyclic aromatic compounds (PACs) is considered a major pathway to isolated lakes and bogs in the Athabasca oil sands region (AOSR), Canada. However, the suite of PACs measured has been ...

(John Wiley and Sons Inc., 1996)1 The selectivity of action of boldine and the related aporphine alkaloids, predicentrine (9-O-methylboldine) and glaucine (2,9-O-dimethylboldine) on α1-adrenoceptor subtypes was studied by examining [3H]-prazosin competition ...
-
(2012)An almost complete postcranial skeleton recovered from late Maastrichtian beds of central Chile, which can be confidently referred to the clade Elasmosauridae (Sauropterygia: Plesiosauroidea), is described. The material ...
-
(Scholars Research Library, 2016)We employed a formal QSAR method to find the main interactions regulating the variation of the ability to inhibit the germination of Lactuca sativa seeds by a small group of phenolic acids. The same techique was employed ...

A Proteome Map of Axoglial Specializations Isolated and Purified from Human Central Nervous System (WILEY-LISS, DIV JOHN WILEY & SONS INC, 2010-09-09)Compact myelin, the paranode, and the juxtaparanode are discrete domains that are formed on myelinated axons. In humans, neurological disorders associated with loss of myelin, including Multiple Sclerosis, often also ...
-
(2012)We present a model of single species fishery which alternates closed seasons with pulse captures. The novelty is that the length of a closed season is determined by the remaining stock size after the last capture. The ...
-
(2011)This work presents a new pulse vaccination strategy for a SIS (susceptibleinfectivesusceptible) disease in an endemic context. Here, given a time of vaccination, the instant of the next one is not predetermined, but it is ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2010-06-04)Late Quaternary temperature estimates from the mid latitudes of the Australian region suggest a breakdown in the tight coupling observed between oceanic and atmospheric temperatures over the recent past that has significant ...
-
(Elsevier Science, 1987-06-05)The electronic structure of 1-(2,5-dimethoxy-4-nitrophenyl)-2-aminopropane (DON) was calculated at the CND0/2 level, and the racemic compound was synthesized and found to be hallucinogenic at doses of 4 mg. DON differs ...
