Forsythia suspensa Leaves Triterpenoids Induce Breast Cancer Cell Apoptosis via the Mitochondrial Pathway

open access: yesFood Science &Nutrition, Volume 13, Issue 8, August 2025.
FLT has a good antiproliferative activity against breast cancer cells. FLT promoted apoptosis in MCF‐7 and MDA‐MB‐231 cells through the mitochondrial pathway. The possible mechanism is that FLT affects the expression of the mitochondrial Bcl‐2 family by promoting mitochondrial division mediated by DRP1 and FIS1, thereby activating caspase‐3 and ...

The Distribution of Lianas and Their Change in Abundance in Temperate Forests Over the Past 45 Years [PDF]

open access: yes, 2006
Lianas (woody vines) are an important and dynamic component of many forests throughout the world, and increases in CO2, mean winter temperature, and forest fragmentation may promote their growth and proliferation in temperate forests.

Environmental Isotope Tracers Constrain River—Groundwater Interactions in a Stream Vulnerable to Mining Impacts

open access: yesHydrological Processes, Volume 39, Issue 8, August 2025.
A range of stable and radioactive isotope tracers found that very old (> 500 ka) and intermediate (> 50 ka) groundwater sustains baseflow to the Carmichael River in central Queensland, Australia. Sections of the stream were found to become losing during major flood events, although groundwater recharge from river leakage was generally limited. Findings

Non-random Vessel Distribution in Woods: Patterns, Modes, Diversity, Correlations [PDF]

open access: yes, 2009
Vessel grouping is a form of non-random distribution that becomes functionally valuable when the background consists of non-conductive imperforate tracheary elements (fiber-tracheids and libriform fibers); ungrouped vessels, randomly placed, often occur ...

Insights From the ‘Black Box’: Survival Strategies of Wheat Rusts and Their Epidemiological Significance

open access: yesPlant Pathology, Volume 74, Issue 6, Page 1504-1518, August 2025.
Literature demonstrates that wheat rusts can survive through sexual reproduction on alternate hosts, asexual reproduction on wild grasses or volunteers and migration to more favourable areas during critical periods. ABSTRACT Survival between cropping seasons is a challenge for crop pathogens and can dramatically impact epidemic recurrence and ...

Niche Differentiation of Three Terrestrial Isopod Species Based on DNA Metabarcoding

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Species coexistence is a hot topic in ecology, with niche differentiation playing a key role in reducing interspecific competition. This study investigates the dietary habits and niche differentiation of three terrestrial isopod species (Armadillidium vulgare, Sphaeroma raffaelei, and Trachelipus semiproiectus) using DNA metabarcoding technology.
