MECHANISM OF EFFICIENCY OF SELECTED NANOSYSTEMS INTENDED FOR CONSOLIDATION OF POROUS MATERIALS [PDF]

Civil Engineering Journal, 2019
Over the past 20 years, the possible usage of disperse and colloid systems of organic consolidation agents as well as mineral systems with particle size in nanodimensions in the context of cultural heritage carehas been examined ...

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Cancer cell growth and survival as a system-level property sustained by enhanced glycolysis and mitochondrial metabolic remodeling [PDF]

Frontiers in Physiology, 2012
Systems Biology holds that complex cellular functions are generated as system-level properties endowed with robustness, each involving large networks of molecular determinants, generally identified by "omics" analyses. In this paper we describe four basic cancer cell properties that can easily be investigated in vitro: enhanced proliferation, evasion ...

Electromagnetic Field in Hybrid Quantum Plasmonic-Photonic Systems

Condensed Matter, 2018
We study excitations and quantum optical properties of hybrid networks made up of metal nanoparticles, semiconductor quantum dots and molecules. Such processes can be used for the localization and the guiding of the electromagnetic field. Localized modes

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

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

FEBS 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 ...

System‐level changes following invasion caused by disruption of functional relationships among plant and soil properties [PDF]

Ecosphere, 2015
The ecological impacts of invasive plants have served to justify the cost of their management, which is estimated to exceed $1 billion annually in the US alone. However, our understanding of the ecological impacts of most invasive plants is extremely limited, and when known, interpretation is confounded with varied measurements and methods.

Influence of Enzymatic Acylation on the Stability and Antioxidant Properties of Cyanidin-3-O-Glucoside in Both Aqueous and Lipid Systems

Molecules
Cyanidin-3-O-glucoside (C3G) was used as a substrate for enzymatic acylation, and different compounds (methyl n-octanoate and methyl salicylate) were selected as acyl donors.

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

FEBS 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.

Impact of Control System Structure and Performance of Inventory Goods Flow System with Long-Variable Delay

Elektronika ir Elektrotechnika, 2018
In this paper, we use a mathematical model of a inventory system with time-varying delivery delay and three control systems  in order to compare their properties for the goods flow optimization problem in the inventory systems.
