Massively Introduced Managed Species and Their Consequences for Plant–Pollinator Interactions

, 2017
Since the rise of agriculture, human populations have domesticated plant and animal species to fulfil their needs. With modern agriculture, a limited number of these species has been massively produced over large areas at high local densities.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

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.

Multi‐Species Canopy Latrines in Costa Rican Cloud Forests: A Mammal Interactions Hub in a Single Tree Species

Ecology and Evolution
We report the discovery of arboreal multi‐species mammal latrines in montane cloud forests of Costa Rica. We surveyed 169 trees from 29 species. Canopy multi‐species latrines were only found in 11 individuals of a single tree species, Ficus tuerckheimii.

First records of the rhododendron leafhopper (Graphocephala fennahi) (Hemiptera: Auchenorrhyncha: Cicadellidae) from the Czech Republic

Plant Protection Science, 2005
In summer and autumn of 2004 the cicadellid leafhopper species Graphocephala fennahi was detected in the Czech Republic for the first time as a new alien insect species feeding on Rhododendron. The species is native to North America and was introduced in

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Epiphytic bacteria on lettuce affect the feeding behavior of an invasive pest slug

Acta Agrobotanica, 2017
Plant–animal interactions are not isolated pairwise relationships but are always accompanied by diverse assemblages of microbes. Additional to direct effects of microorganisms on their hosts, recent investigations demonstrated that bacteria associated ...

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

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 ...

Effects of organic and ‘low input’ production methods on food quality and safety [PDF]

, 2007
The intensification of agricultural production in the last century has resulted in a significant loss of biodiversity, environmental problems and associated societal costs.

Self-organization, scaling and collapse in a coupled automaton model of foragers and vegetation resources with seed dispersal

, 2009
We introduce a model of traveling agents ({\it e.g.} frugivorous animals) who feed on randomly located vegetation patches and disperse their seeds, thus modifying the spatial distribution of resources in the long term.

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

Molecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...
