Ecología Austral, 2018 Pre-dispersal flters imposed on the seed stage can alter the likelihood of seed dispersal. We evaluate pre-dispersal seed loss due to predation by insects and abortion in Prosopis flexuosa and P. chilensis. This study was conducted in two protected areas

Molecular Oncology, EarlyView.Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Oilbirds disperse large seeds at longer distance than extinct megafauna
Scientific Reports, 2021 The extinction of megafauna in the Neotropics is thought to have reduced the potential of large seeds to be dispersed over long distances by endozoochory (ingestion by animals), but some seed dispersal systems have not been considered.

Long Distance Seed Dispersal by Forest Elephants
Frontiers in Ecology and Evolution, 2021 By dispersing seeds long distances, large, fruit-eating animals influence plant population spread and community dynamics. After fruit consumption, animal gut passage time and movement determine seed dispersal patterns and distances.

Molecular Oncology, EarlyView.Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Between-site differences in the scale of dispersal and gene flow in red oak. [PDF]
PLoS ONE, 2012 Nut-bearing trees, including oaks (Quercus spp.), are considered to be highly dispersal limited, leading to concerns about their ability to colonize new sites or migrate in response to climate change.

Seed dispersal by deception: A game between mimetic seeds and their bird dispersers. [PDF]
Plant DiversMimetic seeds attract birds to disperse seeds mainly by mimicking fleshy fruits or arillate seeds, however, they provide little nutritive reward for bird dispersers. The key characteristics of mimetic seeds are conspicuous seed color, hard seed coat, certain toxic secondary metabolites, and perhaps smooth waxy layer.

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma
Molecular Oncology, EarlyView.Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

DNA fingerprinting validates seed dispersal curves from observational studies in the neotropical legume parkia. [PDF]
PLoS ONE, 2012 Determining the distances over which seeds are dispersed is a crucial component for examining spatial patterns of seed dispersal and their consequences for plant reproductive success and population structure.
