Endogenous Ceramide 24:1 Constrains Th17‐Driven Neutrophilic Inflammation by Antagonizing EP2 Signaling

open access: yesAdvanced Science, EarlyView.
Cer24:1 levels are reduced in neutrophilic asthma and inversely correlate with disease severity and airway neutrophilia. Restoring Cer24:1 suppresses pathogenic Th17 differentiation by engaging EP2 on CD4+ T cells, thereby dampening the JAK2–STAT3–RORγt axis and reducing IL‐17 production.

Honey bees and wild pollinators differ in their preference for and use of introduced floral resources

open access: yesEcology and Evolution, 2020
Introduced plants may be important foraging resources for honey bees and wild pollinators, but how often and why pollinators visit introduced plants across an entire plant community is not well understood.

Cis‐ and Trans‐Regulatory Factors Independently Shape Phenotypic Heterogeneity of Retinitis Pigmentosa

open access: yesAdvanced Science, EarlyView.
A zebrafish model carrying an identical human RHO S334X allele reveals two independent genetic layers shaping retinitis pigmentosa (RP) severity: a protective 3‐bp cis‐regulatory insertion that attenuates transgene expression, and a dominant trans‐acting modifier that restores a severe phenotype.

Do managed bees drive parasite spread and emergence in wild bees?

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2016
Bees have been managed and utilised for honey production for centuries and, more recently, pollination services. Since the mid 20th Century, the use and production of managed bees has intensified with hundreds of thousands of hives being moved across ...

Spontaneous rupture of the lymph nodes as a cause of haemoabdomen in two canine lymphoma patients

open access: yesVeterinární Medicína, 2020
Non-traumatic haemoabdomen in dogs usually occurs due to abdominal neoplasia, coagulopathies or organ torsion. The most common sources of bleeding in neoplastic cases are the spleen and liver, but other abdominal organs can also be involved.

Wild bee and floral diversity co-vary in response to the direct and indirect impacts of land use [PDF]

open access: yes, 2017
Loss of habitat area and diversity poses a threat to communities of wild pollinators and flowering plants in agricultural landscapes. Pollinators, such as wild bees, and insect‐pollinated plants are two groups of organisms that closely interact ...
