Nectar traits differ between pollination syndromes in Balsaminaceae [PDF]

Annals of Botany, 2019
Abstract Background and Aims The attractiveness of nectar rewards depends both on the quantity of nectar produced and on its chemical composition. It is known that nectar quantity and chemical composition can differ in plant species depending on the main pollinator associated with the species.

Sequence of Immunological Events During IgE‐Mediated Allergic Reactions to Food

Allergy, EarlyView.
ABSTRACT Food allergies (FA) represent a significant global health burden. Upon allergen re‐exposure, allergic patients exhibit a sequence of symptoms that vary in terms of affected organ systems, severity, time of onset and allergen reactivity thresholds.

Variation in plant-animal interactions along an elevational gradient of moist forest in a semiarid area of Brazil

Acta Botânica Brasílica, 2016
Pollination and dispersal are critical ecological processes that directly affect the reproductive success of plants and are important for understanding the structure of plant communities.

Art v 1 and Amb a 4 Co‐Sensitization Identifies Italian Patients at Risk for Mugwort‐Celery‐Spice Syndrome

Allergy, EarlyView.
Three molecular profiles identified among Art v 1/Amb a 4‐sensitized patients: Art v 1 monosensitization, Amb a 4 monosensitization, and dual sensitization to both allergens. Art v 1 monosensitization was predominantly associated with allergic rhinitis, reflecting a classical airborne allergy pattern.

Pollination Systems of Palms (Arecaceae)

Journal of Pollination Ecology
A review is given of pollination systems in the palm family (Arecaceae). Pollination studies of 149 species (6% of the total number) in 60 genera (33% of the total number) are reviewed. The majority of these studies (75%) are of Neotropical palms.

Pollination and floral biology of Adonis vernalis L. (Ranunculaceae) – a case study of threatened species

Acta Societatis Botanicorum Poloniae, 2014
Although the knowledge of pollination systems of rare and threatened species is one of the principles for development of optimal conservation and management strategies, the data about their pollination requirements are scarce or incomplete.

Serotonin Degradation and Lipid Metabolism Regulate Human Tc2 Cell Effector Functions

Allergy, EarlyView.
Human Tc2 cells exhibit a metabolically active phenotype characterized by enhanced glycolysis, mitochondrial respiration, and fatty acid uptake dependent on PPARγ. Alarmins strongly amplify IL‐5 and IL‐13 production in Tc2 cells, supporting a shared immunometabolic program across type 2 lymphocytes.

Specialization, generalization, and pollination syndromes: the role of pollinator competition

Evolutionary Ecology
The relative importance of specialization and generalization has prompted a lively debate in studies of plant-pollinator associations and pollination syndromes. However, most work focuses on floral and pollinator morphology as determinants of interactions, with less consideration of how pollinator competition may determine interactions with plants.

Ginger and the beetle: Evidence of primitive pollination system in a Himalayan endemic alpine ginger (Roscoea alpina, Zingiberaceae). [PDF]

PLoS ONE, 2017
The Himalayan endemic alpine genus Roscoea, like other members of ginger family, exhibits the combination of floral traits that would fit pollination by long distant foragers such as bees, birds or flies.

Randomized, single‐centre, double‐blinded repeated dose investigation of safety and tolerability of ocular administrations of a novel silica eye drop product in healthy volunteers

Acta Ophthalmologica, EarlyView.
Abstract Purpose Managing ocular diseases often requires frequent eye drop administration, which can challenge patient compliance. A long‐acting eye drop technology using an amorphous synthetic silica composite was developed to address this. Our study aimed to assess the safety and tolerability of the Silica Eye Drop platform in healthy volunteers over
