An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

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 ...

Clarifying life lost due to cold and heat: a new approach using annual time series. [PDF]

open access: yes, 2015
OBJECTIVE: To clarify whether deaths associated with hot and cold days are among the frail who would have died anyway in the next few weeks or months. DESIGN: Time series regression analysis of annual deaths in relation to annual summaries of cold and ...

Development of Sn-9Zn Solder Alloy by Adding Bismuth

open access: yesDiyala Journal of Engineering Sciences, 2020
Tin-Zinc based on solder is a probable changing of lead element solder as a result of its enhanced mechanical characteristics. This alloy needs to be studied and explored to get a usable solder alloy having better properties.

SPECIFIC HEAT IN THE THERMODYNAMICS OF CLUSTERS [PDF]

open access: yesSurface Review and Letters, 1996
The thermodynamic properties such as the specific heat are uniquely determined by the second moments of the energy distribution for a given ensemble averaging. However for small particle numbers the results depend on the ensemble chosen. We calculated the specific heat for both the canonical and the microcanonical ensemble for the same van der Waals ...

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.

Moisture dependent thermal properties of selected vegetables in Akwa Ibom State, Nigeria

open access: yesResearch in Agricultural Engineering, 2019
The thermal properties of some selected vegetables in Akwa Ibom State, Nigeria were investigated. The specific heat, thermal conductivity and thermal diffusivity for the five selected vegetables (Afang, Nkong, Atama, Editan and Nton) were determined and ...
