Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

open access: yesFEBS Open Bio, EarlyView.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

Simulations of stable compact proton beam acceleration from a two-ion-species ultrathin foil

open access: yes, 2011
We report stable laser-driven proton beam acceleration from ultrathin foils consisting of two ion species: heavier carbon ions and lighter protons. Multi-dimensional particle-in-cell (PIC) simulations show that the radiation pressure leads to very fast ...

Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, EarlyView.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

Sustainable bioplastics manufacturing from renewable sources

open access: yesFEBS Open Bio, EarlyView.
Bioplastics are manufactured by using polymers from different bio‐based sources. These novel materials not only offer biodegradability but also possess various functional properties that make them suitable for diverse applications. Recent developments in the preparation of bioplastics are reported, highlighting the distinct properties of each type of ...

A Theoretical Framework of Haptic Processing in Automotive User Interfaces and Its Implications on Design and Engineering

open access: yesFrontiers in Psychology, 2019
Driving a car is a highly visual task. Despite the trend towards increased driver assistance and autonomous vehicles, drivers still need to interact with the car for both driving and non-driving relevant tasks, at times simultaneously.

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

open access: yesFEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Determination of carbon-carbon connectivities, assignment of quaternary carbons, and extraction of carbon-carbon coupling constants by carbon-relayed hydrogen-carbon spectroscopy

open access: yesJournal of Magnetic Resonance (1969), 1985
Nowadays many possibilities exist to elucidate carbon-carbon connectivity. In hydrogen-bearing carbon systems C-C connectivities can be traced out most conveniently in an indirect way by a combination of H-H COSY (I) and H-C CQSY (2). In case of overlapping ‘proton signals ambiguities can be removed by heteronuclear relayed spectroscopy (3) and ...

Cutting carbon, not the economy [PDF]

open access: yes
A drastic change in the way we produce and consume energy is necessary to contain the risk of global environmental catastrophe. For its part, the EU has set agreed to a greenhouse gas reduction target of 80-95 percent by 2050, compared to 1990. However,

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

open access: yesFEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...
