  • Experiments can go beyond studying if plant traits have an effect to testing what these effects are

    Fungi compete for space and resources in Q. petraea seeds , and have negative interactions with bacteria in Populus trichocarpa seeds . Similar competitive exclusion has been observed in floral stigma communities , and in dormant seeds within the soil . However, seed microbes can also coexist via niche partitioning and other interactions. For example, TorresCortés et…

  • Many studies suggest a link between aging and stress resistance

    It was also reported previously that females live longer and are more resistant to different stresses than male flies. As a next step, we checked ‘life-quality’ indices, conventionally measured for Drosophila and other animal models of aging. Since R. rosea is known mainly by its adaptogenic properties, we also checked age-related changes in stress resistance…

  • Treatment of adipocytes with resveratrol significantly increased expression levels of SIRT1 mRNA

    Likewise, production of free radicals was reduced in human stratum corneum following topical treatment with resveratrol for 24 hr. Collectively, resveratrol exhibits antioxidant properties both in vitro and in vivo.Oxidative stress has been considered as a major contributor to the development of skin cancers, such as melanoma. Accordingly, antioxidants, including resveratrol, have been used to…

  • Herbivores also harbored a more diverse microbial community than carnivores

    A large amount of variation was explained by PCo1 , and our attempts to determine the factors driving this variation led us to look at specific taxonomic groups that may be important. We did this in two ways. First, we produced a biplot with the make emperor.py script, showing the prevalence of bacterial families in the…

  • A diet high in both vitamin C and iron may lead to an overload of iron

    Diet plays a role in regulating the inflammatory conditions within the body. For example, we found that the intake of the precursor FA is associated with the plasma levels of some oxylipins in DAISY. While it may not be possible to prevent inflammation causing insults, it may be possible to identify the modifiable interventions that reduce…

  • Starch is critical to human society given its versatile uses

    The most documented cardiovascular activity of flavan- 3-ols is their positive effects on vasculature. For example, biomarker-estimated flavan-3-ol intake was inversely associated with reduced systolic and diastolic blood pressure in the EPIC Norfolk study . Additionally, flavan-3-ols have also been shown to reduce arterial stiffness . The exact mechanisms behind these improvements likely include the…

  • All nests monitored for overwinter survival were located in woodlands or forests

    Accounting for the identity of species shows that pollinator communities in different farm fields across large areas basically consist of variations of the same core set of species that prefer to forage on crops and that are augmented with the occasional new species. So while there is little doubt that a reduction in the local…

  • The radius of the hyperbolic space differed depending on the cell types

    Variations in gene expression across samples taken from different clusters, which represent different cell types, tissues and disease states, show more complicated distributions and have attracted a great deal of attention. To study the geometric structure of expression space globally, we selected 100 samples randomly from the whole population instead of local clusters, and performed the…

  • This high level of similarity suggests that the two groups share an origin

    Homologous recombination typically involves relatively small pieces of DNA , which suggests entry of donor DNA into the bacterial cell via transformation. However, not all species with significant levels of recombination, such as Escherichia coli, are typically competent for transformation , and it is also possible that large pieces of DNA entering the cell via…

  • One bowl of blueberries was painted with BA and the other solvent

    Surprisingly, D. suzukii did not show avoidance to CO2 at levels that elicit robust avoidance in D. melanogaster . These results suggest that while D. suzukii can detect CO2 other changes in processing this sensory information have occurred. Since D. suzukii are attracted to ripening fruits which emit CO2, we also tested whether CO2 can enhance attraction in the presence of food…
