Electrical pulse stimulation reflecting the episodic nature of real‐life exercise modulates metabolic and secretory profile of primary human myotubes

open access: yesFEBS Open Bio, EarlyView.
Here, we introduced an intermittent electrical stimulation protocol mimicking the episodic nature of real‐life exercise in vitro by alternating low‐ and high‐frequency stimulation. In comparison with widely used continuous stimulation, it enhanced the rate of glucose and fatty acid oxidation, but not the myokine release.

Biota and Biomolecules in Extreme Environments on Earth: Implications for Life Detection on Mars

open access: yesLife, 2014
The three main requirements for life as we know it are the presence of organic compounds, liquid water, and free energy. Several groups of organic compounds (e.g., amino acids, nucleobases, lipids) occur in all life forms on Earth and are used as ...

HSP70 governs permeability and mechanotransduction in primary human endothelial cells

open access: yesFEBS Open Bio, EarlyView.
HSP70 chemical inhibition reduces endothelial cell proliferation and increases permeability, the latter supported by normal interendothelial junctional protein distribution. HSP70 also plays a role in shear stress response, a hemodynamic force naturally present in blood vessels and correlated with vessel protection.

Overview of molecular signatures of senescence and associated resources: pros and cons

open access: yesFEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Tracing early life on Mars: lessons from organics produced in high-altitude hotsprings of Ladakh

open access: yesProgress in Earth and Planetary Science
Hotspring waters have traditionally been recognized for their therapeutic benefits. More recently, high-altitude hotsprings have received attention for astrobiological studies because they replicate several parameters of extreme conditions that once ...

A PROPAGAÇÃO DO ERRO DO pKa DA ÁGUA NOS LIVROS DE QUÍMICA ORGÂNICA [PDF]

open access: yesQuímica Nova
In organic chemistry, the pKa is a property used to compare the acidity behavior for many substances, and to locate the position of equilibria in acid-base reactions and to provide information about structure and reactivity.

Naked cuticle is essential for Drosophila wing development beyond Wingless signaling

open access: yesFEBS Open Bio, EarlyView.
Naked cuticle (Nkd), a Wnt signaling inhibitor, assumes extensive roles in Drosophila wing development. Overexpressing Nkd causes smaller, crumpled wings, while also perturbing multiple signaling pathways and developmental genes. A specific region (R1S) is critical for Nkd's function as a signaling integrator, offering new insights for studying its ...
