Inula viscosa (L.) Aiton Ethanolic Extract Inhibits the Growth of Human AGS and A549 Cancer Cell Lines

Chemistry &Biodiversity, Volume 20, Issue 3, March 2023., 2023
Abstract The present study shows the chemical profile and cytotoxic properties of the ethanolic extracts of Inula viscosa from Northeast Algeria. The extract was obtained by maceration using ethanol. Its phenolic profile was determined using ultra‐high‐performance liquid chromatography coupled with a diode array detector and an electrospray mass ...

Labdane conjugates protect cardiomyocytes from doxorubicin‐induced cardiotoxicity

Drug Development Research, Volume 84, Issue 1, Page 84-95, February 2023., 2023
Abstract The cardiovascular side effects associated with doxorubicin (DOX), a wide spectrum anticancer drug, have limited its clinical application. Therefore, to explore novel strategies with cardioprotective effects, a series of new labdane conjugates were prepared (6a–6c and 8a–8d) from the natural diterpene labdanodiol (1).

Rainy years counteract negative effects of drought on taxonomic, functional and phylogenetic diversity: Resilience in annual plant communities

Journal of Ecology, Volume 110, Issue 10, Page 2308-2320, October 2022., 2022
Our results provide important insights into the responses of semiarid annual plant communities under a climate change scenario. Experimental rain exclusion consistently decreased diversity (taxonomic and functional) but to a lesser extent than interannual rain patterns, that result in deep diversity losses during drought events but rapid recovery in ...

Antiparasitic Effects of Asteraceae Species Extracts on Echinococcus granulosus s.s

Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022
Cystic echinococcosis is a zoonotic disease caused by the parasite Echinococcus granulosus sensu lato (s.l.), which is worldwide distributed and causes long‐lasting infections in animals and humans. The existing treatment is limited to the use of benzimidazoles, mainly albendazole (ABZ).

Every bit helps: The functional role of individuals in assembling any plant community, from the richest to monospecific ones

Journal of Vegetation Science, Volume 32, Issue 5, September/October 2021., 2021
We introduce the idea of a phenotype‐based community ecology, which accounts for the variation between individuals (phenotypes both affected by and affecting the environment) while considering their interactions with neighbours. This framework could help explaining coexistence from rich plant communities to monocultures.

Relative humidity predominantly determines long‐term biocrust‐forming lichen cover in drylands under climate change

Journal of Ecology, Volume 109, Issue 3, Page 1370-1385, March 2021., 2021
Our modelling results show that a decrease in relative humidity, rather than an increase in temperature, may be the key factor for the survival of the lichen D. diacapsis under climate change and that effects of increased CO2 levels might be offset by a reduction in non‐rainfall water inputs in the future.

Antiprotozoal Compounds from Urolepis hecatantha (Asteraceae)

Evidence-Based Complementary and Alternative Medicine, Volume 2021, Issue 1, 2021., 2021
The dewaxed dichloromethane extract of Urolepis hecatantha and the compounds isolated from it were tested for their in vitro activity on Trypanosoma cruzi epimastigotes and Leishmania infantum promastigotes. The extract of U. hecatantha showed activity against both parasites with IC50 values of 7 µg/mL and 31 µg/mL, respectively.
