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 ...

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.

Internal resonance between in-plane and out-of-plane modes of vibration of inclined cables subjected to vertical support excitation

open access: yes, 2011
Inclined cables are important structural elements of cable-stayed bridges. When the bridge deck oscillates, large amplitude cable vibrations can arise in various modes as a result of the low cable damping, parametric excitation or non-linear modal ...

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

STATISTICAL LINEARIZATION METHOD OF DUFFING OSCILLATOR UNDER GAUSSIAN WHITE NOISE EXCITATION [PDF]

open access: yes
In this paper is presented a statistical linearization method of Duffing oscillator under Gaussian white noise excitation. Duffing oscillator’s dispersion response to various nonlinearities and spectral intensities is obtained by the statistical ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Glottal Flow Derivative Modeling With The

open access: yes, 2007
This paper discusses a method for estimating glottal flow derivative model parameters using the wavelet-smoothed excitation. The excitation is first estimated using the Weighted Recursive Least Squares with Variable Forgetting Factor algorithm.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

A Study on Structural Optimization by Adjusting Plate Thickness under Displacement Excitation using FEM [PDF]

open access: yes
In this paper, taking into consideration future manufacturing methods using one-piece molding by aluminum extrusion, the target structures are a thin plate structure that extends the suspension of a car or a battery box cover of an electric vehicle ...
