We initially studied the effect of depression on dementia incidence across four subgroups characterized by courses of depressive symptoms.

Clinical Manifestations.

Background: Accumulating evidence has shown the neuroprotective effects of estrogen on cognition function, for example delaying the cognitive deterioration in patients with Alzheimer's disease (AD). However, the clinical usage of estrogen in AD remains controversial. The cytochrome P450 aromatase encoded by CYP19A1, is a key enzyme catalyzing the C19 androgen conversion to C18 estrogen, which induces testosterone to estradiol and androstenedione to estrone.

Clinical Manifestations.

Background: Objective Subtle Cognitive Decline (obj-SCD) can be identified through standardized neuropsychological tests and may precede the development of Mild Cognitive Impairment (MCI). Nevertheless, current clinical and research criteria lack a standardized protocol for identifying obj-SCD. This study introduces cutting-edge sensitive methods to characterize obj-SCD, defined through Alzheimer's disease (AD) biomarker-based longitudinal cognitive performance in episodic memory.

Method: An individual-level Regional Radiomics Similarity Network (R2SN) for 487 patients with AD continuum (376 with NPSs vs. 111 without NPSs) were developed to find the R2SN connections associated with NPSs and refine the subtypes of NPS in the AD continuum.

Hierarchical-Porous Hollow Nitrogen-Doped Carbon-Supported Pt Alloy Catalysts with a Controllable Triheterointerface for Methanol Electrooxidation.

Carbon-supported Pt-based catalysts are the most effective catalysts for direct methanol fuel cells (DMFCs). However, challenges such as high Pt loading, cost, and susceptibility to CO poisoning severely hinder the development of DMFCs. In this paper, CoFeO@polymer@ZIF-67 is prepared successfully through sequential solution polymerization and in situ growth with modified CoFeO as the core.

Effectiveness and Safety of Glue-based Dural Closure in Cranial Surgery: A Retrospective Cohort Study.

Dural closure is a crucial step in cranial surgery, essential for preventing complications like cerebrospinal fluid leakage, wound infections, and meningitis. Traditional suturing techniques, however, pose challenges such as technical difficulty and the potential for tissue damage. This retrospective study aimed to assess the safety and effectiveness of a nonsuture dural closure method using medical glue for direct adhesion of a patch to the dura mater.

Tuning Surface Valences of Nanoengagers to Enhance Their Structural Advantages for Efficiently Redirecting T Cells against Solid Tumors.

The nanoengager strategy, which enhances receptor signaling responsiveness through a multivalent ligand binding mode, offers a promising approach for improving immune cell redirecting therapy. Increasing nanomaterial platforms have been developed for constructing more flexible and multifunctional nanoengagers, but the different mediating mechanisms from their multivalent nanostructures, compared to original monomolecule engagers, have rarely been discussed. Here, we constructed dual-specificity T cell nanoengagers (TNEs) targeting CD3 and PDL1 receptors based on a polyethylene glycol--polylactic acid (PEG--PLA)-assembled nanoparticle and specifically studied the impact of surface antibody valences on their functional mechanisms, thereby enhancing the structural advantages of TNEs against solid tumors.

Thermosensitive liposome-encapsulated gold nanocages for photothermal-modulated drug release and synergistic photothermal therapy.

Delivery nanosystems have been widely developed to improve the efficacy of chemotherapy. However, their performance regarding the non-specific leakage of drugs remained unsatisfactory. Herein, gold nanocages (AuNCs) were used as carriers and thermo-sensitive liposome (TSL) as a protective shell to design a camptothecin (CPT)-loaded delivery nanosystem (AuNCs/CPT@TSL) for photothermal-modulated drug release.

Background: Individuals with mild cognitive impairment (MCI) commonly exhibit alterations in cortical structures accompanied by a mild decline in cognitive function. While the dual-task paradigm is utilized for MCI detection, its cortical mechanism remains incompletely understood. This study seeks to explore cortical structural changes and cognitive decline using the dual-task paradigm in individuals with MCI.

Clinical Manifestations.

Background: Evidence has emerged that the inflammation and immune mechanisms are involved in the relationship between hypertension (HTN) and cognitive impairment. We sought (1) to examine the combined effects of HTN and CD33, an immune-related and robust cognitive impairment susceptibility locus, with cognitive function in older adults and further (2) to explore the underlying mechanisms.

Method: This population-based study included 4444 dementia-free participants (age ≥65 years) in MIND-China; of these, data on gray matter volume were available in 1047 persons and cerebral blood flow (CBF) in 85 persons.

Interaction-Enhanced Superradiance of a Rydberg-Atom Array.

We study the superradiant phase transition of an array of Rydberg atoms in a dissipative microwave cavity. Under the interplay of the cavity field and the long-range Rydberg interaction, the steady state of the system exhibits an interaction-enhanced superradiance, with vanishing critical atom-cavity coupling rates at a discrete set of interaction strengths. We find that, while the phenomenon can be analytically understood in the case of a constant all-to-all interaction, the enhanced superradiance persists under typical experimental parameters with spatially dependent interactions, but at modified critical interaction strengths.

Early Warning Signals of the Tipping Point in Strongly Interacting Rydberg Atoms.

The identification of tipping points is essential for the prediction of collapses or other sudden changes in complex systems. Applications include studies of ecology, thermodynamics, climatology, and epidemiology. However, detecting early signs of proximity to a tipping is made challenging by complexity and nonlinearity.

Probing Berry Phase Effect in Topological Surface States.

We have observed the Berry phase effect associated with interband coherence in topological surface states (TSSs) using two-color high-harmonic spectroscopy. This Berry phase accumulates along the evolution path of strong field-driven electron-hole quasiparticles in electronic bands with strong spin-orbit coupling. By introducing a secondary weak field, we perturb the evolution of Dirac fermions in TSSs and thus provide access to the Berry phase.

Flexible Control of Chiral Superconductivity in Optically Driven Nodal Point Superconductors with Antiferromagnetism.

Recent studies have attracted widespread attention on magnet-superconductor hybrid systems with emergent topological superconductivity. Here, we present the Floquet engineering of realistic two-dimensional topological nodal-point superconductors that are composed of antiferromagnetic monolayers in proximity to an s-wave superconductor. We show that Floquet chiral topological superconductivity arises due to light-induced breaking of the effective time-reversal symmetry.

Polymorphic Crystalline Layer at the Crystallization Front.

The morphology and kinetics of the crystal growth front have been poorly explored at the particle level. Here, we experimentally observe the crystal growth front in liquid with single-particle kinetics using colloid systems and reveal a surface layer of polymorphic crystal near the solid-solid transition when the two crystals form a low-energy coherent interface. The thickness of the surface crystal can exceed 50 particles and grows logarithmically with the temperature as approaching the solid-solid transition which follows premelting theory.
