Sampling parental cooperation: temporal fluctuations in starling provisioning and implications for methodology

open access: yesThe European Zoological Journal
Research on parental cooperation is an emerging subfield of behavioural ecology that often lacks standardized methodological framework. A common limitation is the failure to repeatedly sample parental activity throughout the entire nestling stage ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Information-analytic characteristic of the ecological situation in the Smolensk region

open access: yesRUDN Journal of Ecology and Life Safety, 2009
Smolensk region belongs to the regions, where the natural complex retains the satisfactory state, and the menace of the natural ecosystems loss is not high.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Checking to ecological safety and quality grain and flour of the cereal grain cultures by method NMR

open access: yesRUDN Journal of Ecology and Life Safety, 2008
Organic solvents extracts of grain and a flour from it, mainly, contain triglycerids of fatty acids, their decomposition products (di-and monoglycerids), fatty acids and products of their oxidation which together form oil.

Avian mortality associated with medium-voltage distribution lines in selected regions of Armenia: results of a pilot survey [PDF]

open access: yesCaucasiana
Electrocution on medium-voltage distribution lines is a globally recognized threat to birds, yet data from the South Caucasus remain scarce. In Armenia, the magnitude and spatial distribution of this impact have not previously been assessed through ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Influence to ecologies and climate on corrosivecondition of the metallic constructions

open access: yesRUDN Journal of Ecology and Life Safety, 2008
There are different factors that influence corrosive processes, main of them are climate and ecology. Corrosion of the metallic constructions, roofs and different parts of construction projects often leads to their collapse, human victims and material ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
