Metabolomics and Biomarkers for Drug Discovery

open access: yesMetabolites, 2018
Metabolomics and biomarkers are increasingly used in drug discovery and development, and are applied to personalized medicine. Progress in these research areas has increased our understanding of disease pathology and improved therapeutic strategies for ...

Functional expression and subcellular localization of pea polymorphic isoflavone synthase CYP93C18

open access: yesBiologia Plantarum, 2013
Isoflavone synthase (IFS; CYP93C) plays a key role in the biosynthesis of phenolic secondary metabolites, isoflavonoids. These compounds, which are well-known for their benefits to human health and plant defence, are produced mostly in legumes.

Atmospheric dispersion of airborne pollen evidenced by near-surface and columnar measurements in Barcelona, Spain [PDF]

open access: yes, 2016
Hourly measurements of pollen near-surface concentration and lidar-derived profiles of particle backscatter coefficients and of volume and particle depolarization ratios during a 5-day pollination event observed in Barcelona, Spain, between 27 – 31 March,

Self-pollination by sliding pollen in Caulokaempferia coenobialis (Zingiberaceae) [PDF]

open access: yes, 2005
Caulokaempferia coenobialis (Zingiberaceae) forms dense populations on steep cliffs in shady, humid monsoon forests in south China. It produces few consecutively opening bright yellow flowers that are 3 cm long and oriented parallel to the ground.

Quality of the Governing Temperature Variables in WRF in relation to Simulation of Primary Biological Aerosols

open access: yesAdvances in Meteorology, 2015
We have evaluated three prognostic variables in Weather Research and Forecasting (WRF) model, mean daily temperature, daily maximum temperature, and daily minimum temperature using 9 months of model simulations at 36 and 12 km resolution, and compared ...

Pollen selection

open access: yesTheoretical and Applied Genetics, 1992
In recent years a large number of reports have been published hinting about the possible role of selection at the male gametophyte level in natural conditions and its possible use as a tool in plant breeding programs. In this work, the evidence that has so far emerged on gametophytic selection is reviewed, and its relationship to pollen competition ...

A combinatorial approach to angiosperm pollen morphology [PDF]

open access: yes, 2016
Angiosperms (flowering plants) are strikingly diverse. This is clearly expressed in the morphology of their pollen grains, which are characterized by enormous variety in their shape and patterning.

Sensitivity of the grassland-forest ecotone in East African open woodland savannah to historical rainfall variation [PDF]

open access: yes, 2014
. Fossil pollen records provide key insight into the sensitivity of terrestrial ecosystems to climate change at longer time scales. However, tracing vegetation response to relatively modest historical climate fluctuations is often complicated by the ...

How to do a clinical trial? Recommendations from the aerobiological point of view

open access: yesWorld Allergy Organization Journal, 2019
Background: Allergy immunotherapy is still the only treatment of pollen allergy, providing a long-term effect. Clinical trials with pollen allergic patients are in need of validated, high quality pollen data and forecasts in order to grant comparability ...

Modern Pollen Rain in the Tibetan Plateau

open access: yesFrontiers in Earth Science, 2021
The basis for the interpretation of fossil-pollen assemblages in terms of vegetation and climate is the present-day relationship of vegetation and climate to pollen rain.
