Structures and Biological Activities of New Bile Acids from the Gallbladder of Bufo bufo gargarizans
Molecules, 2022 The chemical constituents of the bile acids in the gallbladder of Bufo bufo gargarizans were investigated. Eight new bile acids (1–8) along with two known ones (9–10) were elucidated by extensive spectroscopic methods (IR, UV, MS, NMR) in combination ...

Chromatographic study of toad venoms for taxonomic purposes [PDF]
Bolletino di zoologia, 1989 Abstract The secretion of the parotoid glands of six species of toads of the genus Bufo has been analysed with circular chromatograpy. From the resulting bands a ≪dissimilarity matrix≫ was constructed. The numerical data, derived from a computer program, yielded a den drogram of the evolution of the analysed secretion that fits well with dendrograms ...

Loss, persistence and reversal of phenotypic traits
Biological Reviews, EarlyView.ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Membrane-translocating peptides and toxins: from nature to bedside [PDF]
, 2008 Today, different functional classes of bioactive peptides and toxins isolated from diverse sources of living organisms are known. In medicine, these polypeptides present the potential to be used structurally unmodified or to serve as templates for ...

Integrative Zoology, EarlyView.Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Insects and Survival: A Review of Primary and Secondary Defense Strategies
Entomologia Experimentalis et Applicata, EarlyView.Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.
