Membrane adhesion and domain formation

, 2007
We review theoretical results for the adhesion-induced phase behavior of biomembranes. The focus is on models in which the membranes are represented as discretized elastic sheets with embedded adhesion molecules. We present several mechanism that lead to

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Berry phases and pairing symmetry in Holstein-Hubbard polaron systems

, 1998
We study the tunneling dynamics of dopant-induced hole polarons which are self-localized by electron-phonon coupling in a two-dimensional antiferro- magnet.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS 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 ...

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

FEBS 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 90% minimum effective volume and concentration of lidocaine for ultrasound-guided stellate ganglion blocks in adults: a biased-coin design, up-and-down sequential allocation trial [PDF]

Korean Journal of Anesthesiology
Background As ultrasound imaging technology matured, stellate ganglion blocks (SGBs) have become increasingly precise and safe, and their use in clinical practice has become widespread. However, the 90% minimum effective volume (MEV90) and concentration (

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Effects of tramadol on minimum alveolar concentration (MAC) of isoflurane in rats

British Journal of Anaesthesia, 1999
It has been suggested previously that tramadol increases central nervous system activity and 'lightens' anaesthesia with volatile agents. We assessed the effects of tramadol on the minimum alveolar concentration (MAC) of isoflurane in 56 Wistar rats, instrumented chronically with an arterial and central venous catheter.
