Sweet silver: A formaldehyde-free silver staining using aldoses as developing agents, with enhanced compatibility with mass spectrometry [PDF]

open access: yes, 2008
Protein detection methods after electrophoresis have to be sensitive, homogeneous, and not to impair downstream analysis of proteins by MS. Speed, low cost, and user friendliness are also favored features. Silver staining combines many of these features,

Dipolar Molecular Motor Candidates with Planar Chirality

open access: yesChemistry – A European Journal, EarlyView.
Two prototypes of molecular motors with simultaneous implementation of planar chirality and a permanent dipole have been designed and synthesized in 7 steps with overall yields of 2.8 to 5.5%. Abstract Two molecular motor candidates built around ruthenium(II) centers featuring both planar chirality and a permanent dipole have been synthesized in seven ...

Continuous chemotrophic growth and respiration of Chromatiaceae species at low oxygen concentrations [PDF]

open access: yes, 1992
Endogenous and maximum respiration rates of nine purple sulfur bacterial strains were determined. Endogenous rates were below 10 nmol O2 · (mg protein · min)-1 for sulfur-free cells and 15–35 nmol O2 · (mg protein · min)-1 for cells containg ...

Navigating the Genetic Risk of Chemotherapy‐Induced Hearing Loss in the Stria Vascularis

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Cisplatin is a chemotherapy drug that causes permanent hearing loss by damaging a critical tissue lining the inner ear, called the stria vascularis (SV). Currently, the molecular mechanisms of SV damage are largely unknown and the incidence of ototoxicity in patients cannot be reliably predicted.
