MOLECULAR GENETIC ANALYSIS OF INTERLEUKIN 4 GENE POLYMORPHISM AMONG TELEUTIANS, SHORIANS, AND CAUCASIANS IN KEMEROVO REGION

open access: yesМедицинская иммунология, 2014
. An interleukin 4 polymorphism has been studied in Teleutians, Shorians, and Caucasoids living in the Kemerovo Region. The groups of Teleutians and Caucasoids are characterised with even or close-to-even distribution of the IL-4 alleles.

Giant Bulk Photovoltaic Effect in Two‐Dimensional Topological Ferroelectric Semimetal

open access: yesAdvanced Science, EarlyView.
ABSTRACT Ferroelectric (FE) metals have attracted growing interest because they combine ferroelectricity with metallic behavior and enable polarization‐controlled band topology near the Fermi level. However, the number of known ferroelectric metals is still limited.

Polarization Dynamics in Ferroelectrics: Insights Enabled by Machine Learning Molecular Dynamics

open access: yesAdvanced Science, EarlyView.
Machine learning molecular dynamics is presented as a route to capture polarization switching, domain wall kinetics, topological polar textures, and polar mechanical coupling beyond the limits of conventional atomistic methods. This Perspective surveys recent progress and identifies key methodological directions, including long‐range electrostatics ...

Precision design of dextran-permeated agarose hydrogels matching adipose stem cell adhesion timescales

open access: yesMaterials Today Bio
Viscoelasticity is now recognised as a key parameter in modulating cell behaviour. Tailoring time-dependent materials to elicit specific cellular responses is, however, a challenge because of the intricate relationship between the substrate relaxation ...

Paternal Sperm Gnas‐ICR Epigenetic Programming Contributes to PPP‐Like Phenotypes in Female Offspring

open access: yesAdvanced Science, EarlyView.
A paternal glucocorticoid–sperm Gnas‐ICR axis is linked to ovarian endocrine programming in female offspring. Paternal preconception caffeine exposure elevates corticosterone, promotes sperm Gnas‐ICR hypermethylation, and is associated with ovarian Gnas upregulation, cAMP/PKA/CREB–StAR activation, enhanced estradiol synthesis, and PPP‐like phenotypes ...

Mechanochemical Piezoelectric Catalysis: Advancing the Hydrogenation of Alkenes

open access: yesAdvanced Science, EarlyView.
This study presents mechanochemical piezoelectric catalysis for alkene hydrogenation, eliminating the need for transition metals, H2, and solvents. The method effectively hydrogenates diverse activated and unactivated alkenes and shows potential for modifying bioactive molecules in pharmaceuticals.

Pd‐Catalyzed Asymmetric Dearomative Heck/Tsuji‐Trost Difunctionalization of Naphthalenes

open access: yesAdvanced Science, EarlyView.
We have developed a palladium‐catalyzed asymmetric dearomative Heck/Tsuji‐Trost 1,4‐difunctionalization reaction of naphthalenes, affording 4‐aminospirocyclohexene oxindole products bearing two remote chiral centers. Through the effect of the newly designed chiral sulfinamide phosphine ligand with large steric hindrance, side reactions are inhibited ...

EphB1‐Mediated Transient Blood‐Brain Barrier Opening Facilitates a Ferritin‐Based Nanotherapeutic for Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
We constructed a brain‐targeted AFn‐DPZ nanodrug delivery system and identified EphB1 as its receptor on the blood‐brain barrier (BBB). This system facilitates drug transport across the BBB and thereby ameliorates cognitive impairment in Alzheimer's disease.
