Chemical modification produces species-specific changes in Cucurbitacin Antifeedant effect
(American Chemical Society, 2013-05)
Cucurbitacins are secondary metabolites that mediate insect plant interactions not only as allomones against generalists but also as kairomones for specialist herbivores. This study was undertaken to identify the potential ...
Is molecular chirality connected to supramolecular chirality? the particular case of chiral 2-pyridyl alcohols
(American Chemical Society, 2015-02)
Ten structurally related racemic 2-pyridylmethyl alcohols containing an o-carborane core (1,2-closo-C2B10H10; rac-1a) or m-carborane (1,7-closo-C2B10H10; rac-2a) or p-carborane (1,7-closo-C2B10H10; rac-3a) and their ...
Basic parameters of three star clusters in the Small Magellanic Cloud: Kron 11, Kron 63 and NGC 121
(Wiley Blackwell Publishing, Inc, 2008-12)
We present observations for three star clusters, Kron 11, Kron 63 and NGC 121, in the Small Magellanic Cloud. We have studied their structure and derived their fundamental parameters by means of their luminosity functions, ...
Preparation and characterization of polyvinyl alcohol–pectin cryogels containing enrofloxacin and keratinase as potential transdermal delivery device
(VBRI Press AB, 2016-05-23)
Polyvinyl alcohol (PVA) and polyvinyl alcohol-pectin (PVA-P) cryogels are potential devices for wound healing. These materials have advantages over commercial wound dressings such as: retaining an appropriate level of ...
Potential distribution of the invasive freshwater dinoflagellate Ceratium furcoides (Levander) Langhans (Dinophyta) in South America
(Wiley Blackwell Publishing, Inc, 2016-02)
Dinoflagellates of the genus Ceratium are predominantly found in marine environments, with a few species in inland waters. Over the last decades, the freshwater species Ceratium hirundinella and Ceratium furcoides have ...
Catalytic isoforms Tpk1 and Tpk2 of Candida albicans PKA have non-redundant roles in stress response and glycogen storage
(John Wiley & Sons Ltd, 2009-12)
Candida albicans cAMP-dependent protein kinase (PKA) is coded by two catalytic subunits (TPK1 and TPK2) and one regulatory subunit (BCY1). In this organism the cAMP/PKA signalling pathway mediates basic cellular processes, ...
A new Mesembriornithinae (Aves, Phorusrhacidae) provides new insights into the phylogeny and sensory capabilities of terror birds
(Society of Vertebrate Paleontology, 2015-03)
Terror birds constitute the most outstanding group of the South American Cenozoic avifauna. Considered as apex predators, their hunting skills have recently been examined, but their diversity is still unresolved. Here we ...
Antrodia neotropica sp. nov. (Polyporales, Basidiomycota): a new South American species of Antrodia s.s. from Brazil based on morphological, molecular and ecological data
(Gebruder Borntraeger, 2016-08)
During the revision of the Antrodia species from the Atlantic Forest in southern Brazil,some specimens collected on dead branches of Baccharis (Asteraceae) were found to represent anundescribed species, Antrodia neotropica ...
Fully differential study of ionization in p + H2 collisions near electron - Projectile velocity matching
(IOP Publishing, 2016-01)
We have performed a kinematically complete experiment on ionization of H2 by 75 keV proton impact for electrons ejected with a speed close to the projectile speed. The fully differential data are compared to a three-body ...
Ghrelin binding to serum albumin and its biological impact
(Elsevier Ireland, 2016-07)
Ghrelin is an octanoylated peptide hormone that plays a key role in the regulation of the body weight and glucose homeostasis. In plasma, ghrelin circulates bound to larger proteins whose identities are partially established. ...
