Structural Relaxation and Frequency Dependent Specific Heat in a Supercooled Liquid [PDF]

, 2001
We have studied the relation between the structural relaxation and the frequency dependent thermal response or the specific heat, $c_p(\omega)$, in a supercooled liquid.

Cephalosporin translocation across enterobacterial OmpF and OmpC channels, a filter across the outer membrane

Communications Biology, 2022
The translocation of cephalosporins across enterobacterial OmpF and OmpC channels is monitored in real-time, demonstrating differential permeation of some cephalosporins through OmpF and OmpC.

Dynamic Mean-Field Glass Model with Reversible Mode Coupling and Trivial Hamiltonian

, 2001
Often the current mode coupling theory (MCT) of glass transitions is compared with mean field theories. We explore this possible correspondence. After showing a simple-minded derivation of MCT with some difficulties we give a concise account of our toy ...

Ketogenic Diet as an Epigenetic Therapy in SETD1B‐Related Epilepsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Histone lysine methyltransferases such as SETD1B regulate chromatin structure and gene transcription. Ketone bodies, including butyrate, act as histone deacetylase inhibitors. We report a 4‐year‐old boy with SETD1B‐related absence epilepsy, refractory to conventional medications, who achieved sustained > 90% seizure reduction on the Modified ...
