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

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

AAA+ protein unfoldases—the Moirai of the proteome
FEBS Letters, EarlyView.AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Visual and vestibular reweighting after cyber‐ and space‐sickness
Experimental PhysiologySensory conflicts are widely recognized as the primary drivers of motion sickness (MS), though the underlying integrative processes remain poorly understood. This study investigated sensory reweighting following exposure to two different sensory conflict

Evaluation the effect of erythropoietin on osteoporosis in a microgravity simulation model [PDF]
فصلنامه ابن سینا, 2015 Background: Bone loss is a well-documented phenomenon occurring in humans both in short- and long-term spaceflights. Revealing data on the role of erythropoietin (EPO) in bone formation has led some to suggest that EPO treatment could also play a role in

Functional and Structural Adaptations of Skeletal Muscle to Microgravity [PDF]
, 2001 Our purpose is to summarize the major effects of space travel on skeletal muscle with particular emphasis on factors that alter function. The primary deleterious changes are muscle atrophy and the associated decline in peak force and power.
