Regulation by the Transcriptional Regulator YdcI in E. coli and (p)ppGpp‐Dependent Activation of ydcI Expression

open access: yesMolecular Microbiology, EarlyView.
YdcI, a LysR‐type transcription regulator in Escherichia coli, regulates loci like iraP and mqo. Its expression is induced by (p)ppGpp under stress conditions, and protein levels rise during mid‐exponential growth, connecting its role to stress response and metabolism control. ABSTRACT YdcI, a LysR‐type transcription regulator, has been associated with

Development of In Vitro and In Planta Strategies for Efficient Production of High‐Value Steviol Glycosides

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Steviol glycosides (SGs) are a group of sweet‐tasting diterpene glycosides found in Stevia rebaudiana. Production of high‐value SGs, Rebaudioside D (Reb D) and Reb M, is limited by inefficient conversion of Reb A to Reb D and stevioside to Reb E.

Saturating mutagenesis on the Ser118 residue responsible for the spectral tuning mechanism of the orange/green‐reversible cyanobacteriochrome AM1_1499g1

open access: yesPlant Biology, EarlyView.
This graphical abstract illustrates our systematic site‐saturation mutagenesis at the Ser118 position of the AM1_1499g1 GAF domain. By replacing this single residue, we generated a diverse array of variants with distinct spectral properties, demonstrating the remarkable molecular plasticity of cyanobacteriochromes and their customizability for ...

Intrinsic Photoactive Star ZnPc–Poly(glutamate) Nanoplatforms for Multimodal Glioblastoma Therapy and Brain‐Targeted Delivery

open access: yesAdvanced Functional Materials, Volume 36, Issue 71, 3 September 2026.
An intrinsic photoactive star‐shaped zinc phtalocyanine‐poly(L‐glutamic acid) (ZnPc‐PGA) nanoplatform for multimodal glioblastoma (GBM) therapy and brain‐targeted elivery. A ZnPc‐PGA‐based multifunctional theranostic nanocarrier platform enables image‐guided, multimodal GBM therapy. ZnPc‐PGA nanocarriers support the integration of fluorescence imaging,

Identifying gender disparities on the time to repay microfinance group loans: evidence from Mexico

open access: yesJournal of Applied Economics
This paper investigates how gender disparities affect the time to repay group micro-finance loans using survival analysis. We also control for the effect of the COVID-19 pandemic on the time needed by micro-finance loan borrowers to repay. We use a large

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination
