Advances in large DNA fragment assembly for microbial cell factory engineering

open access: yesQuantitative Biology, Volume 14, Issue 3, September 2026.
Abstract The efficient, rapid, and reliable assembly of DNA fragments is essential for advancing metabolic engineering and synthetic biology. With the rapid advancement of DNA synthesis and assembly technologies, the scale of DNA assembly has expanded from single genes to metabolic pathways and even genomes.

Descent Techniques in Algebraic K-theory

open access: yes, 2023
We investigate two different approaches to describing algebraic K-theory of schemes through descent techniques, one of global nature and the other of local nature.

Analysis and Predictive Modeling of In Vitro Digestive Stability of Tea Polyphenols in 24 Tea Varieties

open access: yesFood Frontiers, Volume 7, Issue 4, July 2026.
This study investigated the dynamic changes of tea polyphenols (TP) during in vitro digestion of 24 representative tea varieties. Electronic nose and color difference technology were employed to construct predictive models, enabling estimation of TP content before and after digestion.

Co‐translational protein targeting to mitochondria in the context of co‐translational protein maturation

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract Mitochondria import the majority of their proteins from the cytosol, creating a fundamental challenge: precursor proteins must be synthesized, maintained in an import‐competent state, and delivered to mitochondrial translocases without premature folding or aggregation. While mitochondrial protein import has been considered a post‐translational

Faithfulness of actions on Riemann-Roch spaces

open access: yes, 2015
Given a faithful action of a finite group G on an algebraic curve X of genus g > 1, we give explicit criteria for the induced action of G on the Riemann-Roch space H^0(X,O_X(D)) to be faithful, where D is a G-invariant divisor on X of degree at least ...

Phenylalanine Versus Tyrosine (Pos. 367/332 in MCT1/MCT4) in the Substrate Binding Site Defines Affinity and Preferred Directionality of Human Monocarboxylate Transporters 1–4

open access: yesActa Physiologica, Volume 242, Issue 7, July 2026.
ABSTRACT Aim Human monocarboxylate transporters 1–4, MCT, are key for the lactate/H+ exchange between glycolytic and oxidative cancer cells, white and red muscle fibers, or in the astrocyte‐neuron shuttle. The common MCT transport mechanism involves three conserved residues, that is, a substrate‐attracting Lys and a conformation‐locking Asp/Arg salt ...

Knot Concordance and Homology Cobordism

open access: yes, 2013
We consider the question: “If the zero-framed surgeries on two oriented knots in S3 are Z-homology cobordant, preserving the homology class of the positive meridians, are the knots themselves concordant?” We show that this question has a negative answer ...

Preclinical and Virtual Models of Mucosal Melanoma: Bridging Translational Gaps in a Rare and Lethal Cancer

open access: yesPigment Cell &Melanoma Research, Volume 39, Issue 4, July 2026.
Integrated physical and virtual modeling provides a scalable framework to overcome sample scarcity, recapitulate mucosal melanoma biology, and accelerate translational discovery toward precision medicine. ABSTRACT Mucosal melanoma (MM) is a rare and lethal subtype of melanoma, disproportionately affecting Asian populations and exhibiting distinct ...
