Time to Compress the Time to First Compression [PDF]

open access: yesJournal of the American Heart Association, 2018
Out‐of‐hospital cardiac arrest (OHCA), often described as the most time‐sensitive and life‐threatening medical condition, remains a major public health problem.[1][1] Survival remains low in most settings, with enormous variation in community outcomes.[2][2] Although several ...

DNABIT Compress-Genome Compression Algorithm [PDF]

open access: yesBioinformation, 2011
Data compression is concerned with how information is organized in data. Efficient storage means removal of redundancy from the data being stored in the DNA molecule. Data compression algorithms remove redundancy and are used to understand biologically important molecules. We present a compression algorithm, "DNABIT Compress" for DNA sequences based on

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
