By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Prooxidant and antioxidant role of reductones and polyphenols in beer.

Kvasný průmysl, 2004
The beer bottled or racked without oxygen presence represents an oxidation-reduction system, in which a relatively slow exchange of electrons among donors and acceptors of electrons takes place.

Several new catalysts for reduction of oxygen in fuel cells [PDF]

, 1970
Test results prove nickel carbide or nitride, nickel-cobalt carbide, titanium carbide or nitride, and intermetallic compounds of the transition or noble metals to be efficient electrocatalysts for oxygen reduction in alkaline electrolytes in low ...

Hematopoietic (stem) cells—The elixir of life?

FEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Therapeutic mechanistic study of novel indole derivatives as SIRTUIN3 modulators in Parkinson’s disease with in vitro evaluation

Scientific Reports
SIRT3 modulates reactive oxygen species and helps to reduce oxidative stress, resulting in a neuroprotective effect in Parkinson’s disease. The work seeks to develop and synthesize novel, effective SIRT3 modulators, which will modify SIRT3 expression and

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Stable magnesium peroxide at high pressure

, 2015
Rocky planets are thought to comprise compounds of Mg and O as these are among the most abundant elements, but knowledge of their stable phases may be incomplete.

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization

FEBS Letters, EarlyView.
CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

Bifunctional catalytic activity of anion-doped LaSrCoO4 for oxygen reduction and evolution reactions

Royal Society Open Science
Here, we synthesized Co-based, anion-incorporated‍ ‌R‌u‌d‌d‌l‌e‌s­d‌e‌n‌–‌Popper perovskite electrocatalysts (LaSrCoO4−x X y ) and compared their catalytic performances in the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).
