Dual Ferroelectric Polarization and Dielectric Response Improvement in Epitaxial HfZrO/HfO Nanolaminates.

Nanolaminates based on ferroelectric polycrystalline doped HfO have gained interest because those compounds show enhanced functional properties. Here, we achieve coexisting improvement of remanent polarization and dielectric permittivity in wake-up-free epitaxial HfZrO/HfO nanolaminates with different numbers of HfO nanolayers if compared with HfZrO single films of equivalent thickness or other reported polycrystalline nanolaminates. Comprehensive structural characterization reveals that the origin of the enhancement must be the larger amount of the orthorhombic phase in the nanolaminates.

Dissecting the role of vitamin B metabolism in craniofacial development through analysis of clinical phenotypes and model organism discoveries.

Vitamin B, otherwise known as cobalamin, is an essential water-soluble vitamin that is obtained from animal derived dietary sources. Mutations in the genes that encode proteins responsible for cobalamin uptake, transport, or processing cause inborn errors of cobalamin metabolism, a group of disorders characterized by accumulation of homocysteine and methylmalonic acid, neurodevelopmental defects, ocular dysfunction, anemia, and failure to thrive. Mild to moderate craniofacial phenotypes have been observed but these phenotypes are not completely penetrant and have not been consistently recognized in the literature.

Biomarkers in head and neck squamous cell carcinoma: unraveling the path to precision immunotherapy.

Recent strides in understanding the molecular underpinnings of head and neck cancers have sparked considerable interest in identifying precise biomarkers that can enhance prognostication and enable personalized treatment strategies. Immunotherapy has particularly revolutionized the therapeutic landscape for head and neck squamous cell carcinoma, offering new avenues for treatment. This review comprehensively examines the application and limitations of the established and emerging/novel biomarkers for head and neck squamous cell carcinoma.

Light-induced targeting enables proteomics on endogenous condensates.

Endogenous condensates with transient constituents are notoriously difficult to study with common biological assays like mass spectrometry and other proteomics profiling. Here, we report a method for light-induced targeting of endogenous condensates (LiTEC) in living cells. LiTEC combines the identification of molecular zip codes that target the endogenous condensates with optogenetics to enable controlled and reversible partitioning of an arbitrary cargo, such as enzymes commonly used in proteomics, into the condensate in a blue light-dependent manner.
