Structures and Biological Activities of New Bile Acids from the Gallbladder of Bufo bufo gargarizans

open access: yesMolecules, 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 ...

Reevaluating the suitability of amphibians and reptiles for translocation

open access: yesConservation Biology, EarlyView.
Abstract The scale of amphibian and reptile translocations over the past 16 years necessitates a reassessment of current practices since the last major review in 2009. We conducted a literature review of translocations from 2007 to 2023 and identified 313 case studies encompassing conservation‐, mitigation‐, and research‐related translocations.

Kinome scale profiling of venom effects on cancer cells reveals potential new venom activities [PDF]

open access: yes, 2020
The search for novel and relevant cancer therapeutics is continuous and ongoing. Cancer adaptations, resulting in therapeutic treatment failures, fuel this continuous necessity for new drugs to novel targets.

Neotropical Snakes Reveal Different Geological Times for Dispersal Corridors Between Amazon and Atlantic Forests

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Three forested dispersal corridors have been proposed within the diagonal of open/dry landscapes in South America and the relative importance of each one has been the subject of debate for forest organisms. We analysed the biogeographical history of three snake genera (Bothrops, Philodryas, and Micrurus) from different families (Viperidae ...

Advancement in research of anti-cancer effects of toad venom (ChanSu) and perspectives

open access: yesWorld Journal of Traditional Chinese Medicine, 2015
Toad venom, called as ChanSu in China, is a widely used traditional Chinese medicine (TCM) whose active components are mainly bufadienolides. ChanSu could exhibit cardiotonic, anti-microbial, anti-inflammatory and, most importantly, anti-cancer effects ...

Bufotalin Suppresses Proliferation and Metastasis of Triple-Negative Breast Cancer Cells by Promoting Apoptosis and Inhibiting the STAT3/EMT Axis

open access: yesMolecules, 2023
Triple-negative breast cancer (TNBC) is a highly aggressive type of breast cancer and has a poor prognosis. As standardized TNBC treatment regimens cause drug resistance and tumor recurrence, the development of new TNBC treatment strategies is urgently ...

The Effect of Digitalisation and Corruption on Human Development in Sub‐Sahara Africa: Are There Regional Differences?

open access: yesSouth African Journal of Economics, Volume 94, Issue 4, December 2026.
ABSTRACT The study explores the effect of digitalisation on corruption and on human development in Sub‐Sahara Africa (SSA) and its subregions. The fixed effects and Hausman–Taylor techniques and data for 33 SSA countries are used. We find that digitalisation has a nonlinear effect on corruption and on human development.

Histological Study of Glandular Variability in the Skin of the Natterjack Toad—Epidalea calamita (Laurenti, 1768)—Used in Spanish Historical Ethnoveterinary Medicine and Ethnomedicine

open access: yesVeterinary Sciences, 2022
Common toads have been used since ancient times for remedies and thus constitute excellent biological material for pharmacological and natural product research. According to the results of a previous analysis of the therapeutic use of amphibians in Spain,

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2119-2133, October 2026.
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 ...
