Predicting how ecological communities will respond to disturbances is notoriously challenging, especially given the variability in species' responses within the same community. Focusing solely on aggregate responses may obscure extinction risks for certain species owing to compensatory effects, emphasizing the need to understand the drivers of the response variability at the species level. Yet, these drivers remain poorly understood.

- This study evaluated the antioxidant and antileishmanial effects of essential oil from Ballota (B.) hirsuta leaves, identifying spathulenol and germacrene D as its main components.
- The essential oil demonstrated moderate antioxidant activity and high antileishmanial effectiveness against both promastigote and amastigote forms of Leishmania, with specific IC values indicating its potency.
- The study also revealed that B. hirsuta EO primarily inhibits the sterol synthesis pathway and suggested that its main compounds may be promising candidates for developing treatments against leishmaniasis.
Within communities, species are wrapped in a set of feedbacks with each other and with their environment. When such feedbacks are strong enough they can generate alternative stable states. So far, research on alternative stable states has mostly focused on systems with a small number of species and a limited diversity of interaction types.

- - TTP is a serious blood disorder requiring immediate treatment with plasma exchange (PE), which has shown varied responses and complications over time.
- - A study at Aziza Othmana Hospital analyzed 26 TTP patients treated with PE from 2010 to 2020, finding a 69% response rate and a 30% mortality rate, highlighting complications like hypocalcemia.
- - Factors influencing successful treatment included a drop in LDH levels within five days and a daily PE regimen, while higher refractory cases suggest that adding rituximab may improve outcomes.
Purpose: Open-access publishing expanded opportunities to give visibility to research results but was accompanied by the proliferation of predatory journals (PJos) that offer expedited publishing but potentially compromise the integrity of research and peer review. To our knowledge, to date, there is no comprehensive global study on the impact of PJos in the field of oncology.
Materials And Methods: A 29 question-based cross-sectional survey was developed to explore knowledge and practices of predatory publishing and analyzed using descriptive statistics and binary logistic regression.
