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.

Geometric construction of optimal designs for dose-responsemodels with two parameters [PDF]

open access: yes
In dose-response studies, the dose range is often restricted due to concerns over drug toxicity and/or efficacy. We derive optimal designs for estimating the underlying dose-response curve for a restricted or unrestricted dose range with respect to a ...

More on halving the complete designs

open access: yes, 1994
A large set of disjoint S(λ; t, k, v) designs, denoted by LS(λ; t, k, v), is a partition of k-subsets of v-set into S(λ; t, k, v) designs. In this paper, we develop some recursive methods to construct large sets ot t-designs.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Large Sets of Disjoint t-Designs

open access: yes, 1996
In this paper, we show how the basis reduction algorithm of Kreher and Radziszowski [4] can be used to construct large sets of disjoint designs with specified automorphisms.

Using integer programming in finding t-designs [PDF]

open access: yes, 2012
A t-design is a combinatorial structure consisting of a collection of blocks over a set of points satisfying certain properties. The existence of t-designs given a set of parameters can be reduced to finding nonnegative integer solutions to a given ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Optimal designs for dose-response models with restricted design spaces [PDF]

open access: yes
In dose response studies, the dose range is often restricted due to concerns over drug toxicity and/or efficacy. We present restricted and unrestricted interval locally optimal designs with respect to a very general class of optimality criteria for ...

Partially Balanced 3-Designs using Mutually Orthogonal Latin Squares

open access: yes, 2022
Not Availablet-designs represent a generalized class of balanced incomplete block designs in which the number of blocks in which any t treatments (t 2) occur together is a constant.

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 ...
