Phosphino-arene ruthenium complexes containing the phosphorus acid anion {P(=O)(OR)(2)} as P-donor

open access: yes, 2001
The cationic complex [Ru(OTf)(P(OH)Ph-2){Ph2P-(eta (6)-arene)}]OTf,2(2a=6'-diphenylphosphino-1'-naphthyl-eta (6)((1-6))-naphthalene, 2b = 6,6'-dimethoxy-2'-diphenylphosphino-eta (6)((1-6))-biphenyl), is shown to react with water/tert-butyl alcohol/THF ...

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

OXYGEN EFFECT ON O-2 DEFICIT AND VO2 KINETICS DURING EXERCISE IN OBSTRUCTIVE PULMONARY-DISEASE

open access: yes, 1995
We evaluated the effect of supplemental O-2 on energy metabolism of hypoxemic humans by measuring O-2 uptake (V over dot O-2) kinetics and other cardiorespiratory parameters in nine male chronic obstructive pulmonary disease (COPD) patients and seven age-

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.
