A two-species stage-structured model for West Nile virus transmission [PDF]

, 2017
We develop a host–vector model of West Nile virus (WNV) transmission that incorporates multiple avian host species as well as host stage-structure (juvenile and adult stages), allowing for both species-specific and stage-specific biting rates of vectors ...

Butterfly Feeding Preferences for Four Zinnia Cultivars [PDF]

Journal of Environmental Horticulture, 2009
Abstract Zinnias are recommended frequently for inclusion in butterfly gardens as nectar sources for adult butterflies, but little is known about butterfly preferences for different zinnia cultivars. We compared numbers and species of butterflies that visited four widely available zinnia cultivars: Zinnia violacea Cav.

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

Molecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Larval Feeding Habits of Five Firefly Species Across Aquatic, Semi-Aquatic, and Terrestrial Lineages

Insects
While adult fireflies are terrestrial, their larvae inhabit various habitat types, and a lack of comprehensive research on the feeding habits of these larvae across different habitats has greatly impeded the development of artificial diets.

Efficiency of some common treatments on infestation level with wax moths, colony strength and honey yield in Northeast Ethiopia: Participatory and comparative analysis

Cogent Food & Agriculture, 2020
Beekeeping is an integral part of livestock-based livelihood system in tropical and subtropical regions of Ethiopia. Despite its importance, the sub-sector is challenged by humble colony strength and honey yield due to pests including wax moths. To avert

Survival and Food Detection by First-Instar \u3ci\u3eMelanoplus Femurrubrum\u3c/i\u3e (Orthoptera: Acrididae) [PDF]

, 2017
Newly hatched Melanoplus femurrubrum (DeGeer) were evaluated for survival without food under various moisture, temperature, and light conditions. Although nymphs survived up to 113 h without food, they required food 48-W h after hatching to ensure ...

Recurrent cancer‐associated ERBB4 mutations are transforming and confer resistance to targeted therapies

Molecular Oncology, EarlyView.
We show that the majority of the 18 analyzed recurrent cancer‐associated ERBB4 mutations are transforming. The most potent mutations are activating, co‐operate with other ERBB receptors, and are sensitive to pan‐ERBB inhibitors. Activating ERBB4 mutations also promote therapy resistance in EGFR‐mutant lung cancer.

A small omnivore fish (Acheilognathus macropterus) reduces both growth and biomass of submerged macrophytes: implications for shallow lake restoration

Knowledge and Management of Aquatic Ecosystems, 2020
Transplantation of submerged macrophytes has been widely used to improve water quality in restoring shallow lakes in China. However, in some lakes, small omnivorous fish predominated the fish assemblages and fed mainly on submerged macrophytes.

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 ...

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.
