Single-molecule fluorescence resonance energy transfer (smFRET) is a powerful technique for studying the structural dynamics of protein molecules or detecting interactions between protein molecules in real time. Due to the high sensitivity in spatial and temporal resolution, smFRET can decipher sub-populations within heterogeneous native state conformations, which are generally lost in traditional measurements due to ensemble averaging. In addition, the single-molecule reconstitution allows protein molecules to be observed for an extensive period of time and can recapitulate the geometry of the cellular environment to retain biological function.

A novel approach to delicately control the phase of a ferroelectric has been developed using a continuous-wave laser scanning annealing (CW-LSA) process. After proper process optimization, the equivalent oxide thickness (EOT) of 3.5 Å with a dielectric constant (κ) of 68 Å is achieved from HZO in a metal-ferroelectric-metal (MFM) capacitor structure.

Objectives: To investigate the most optimal model by combining thymidine kinase 1 (TK1) autoantibody, extracellular protein kinase A (ECPKA) autoantibody, TK1 antigen, C-reactive protein (CRP), age, breed, and sex.
Animals: Serum samples from 1702 dogs were collected from local animal hospitals and referral animal medical centers in Korea.
Article Synopsis
- Encapsulation of materials in nanotubes is a key technique in nanotechnology that creates unique one-dimensional (1D) structures with enhanced functionality.
- Materials trapped inside nanotubes can form low-dimensional polymorphs that have different electrical, optical, and magnetic properties than their bulk counterparts.
- Recent advancements in this field involve various materials like organic molecules and metal compounds, as well as a focus on how geometrical confinement within nanotubes influences their atomic structure and potential applications in electronics and energy storage.
Background: Risk factors and the temporal relationship between atopic dermatitis (AD) and atopic march remain understudied.
Objective: Determine risk factors for atopic march in early-onset AD patients and the temporality between AD and atopic march.
Methods: We used the MarketScan Research Database for our retrospective cohort analysis from 2010 to 2018, comparing infants diagnosed with AD before age 1 with controls without early-onset AD.
