Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells

open access: yesFEBS Open Bio, EarlyView.
Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...

Special endurance coefficients enable the evaluation of running performance

open access: yesScientific Reports
Abstract Running performance from sprint to long distance is largely determined by the interplay between basic speed and endurance. Existing power-law, physiological, and theoretical models describe and explain the characteristic decline in pace with increasing distance.

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

open access: yesFEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Dactolisib outperforms Rapamycin in potentiating apoptosis induced by XPO1, Bcl‐2 and Mcl‐1 blockade in preclinical glioblastoma models

open access: yesFEBS Open Bio, EarlyView.
The PAM pathway and its impact on cellular metabolism. Color‐coded key symbols represent Rapamycin (R, orange, targeting mTOR) and Dactolisib (D, green, targeting PI3K/mTOR), indicating their sites of action. Created with BioRenders.com. Glioblastoma resists therapy through interconnected survival programs.

Coefficient of Restitution of Wet Tennis Balls

open access: yes, 2014
The coefficient of restitution of a damp tennis ball is of interest to tennis players. Using a spray bottle, water was added to a tennis ball and the mass of water on the wet ball was determined. The ball was then dropped from a fixed height of 0.86 m.

Rationally engineered polymeric interfaces for selective and dynamic recognition of vesicular agents

open access: yesFEBS Open Bio, EarlyView.
This review explores how molecularly imprinted polymers can be engineered to recognize complex nanoscale vesicles, including extracellular vesicles and membrane‐enveloped viruses. By tailoring polymer cavities to vesicle surface chemistry and structure, these synthetic receptors support selective detection, separation, and integration with optical ...

Performance of a direct-expansion solar-assisted heat pump for domestic hot water production in Algeria

open access: yesInternational Journal of Renewable Energy Development
The focus of this study is to investigate the energy performance of a direct-expansion solar-assisted heat pump water heating system (DX-SAHPWH). The system consists of an unglazed solar collector-evaporator, which can absorb heat from solar energy and ...
