Epigenetic‑ncRNA crosstalk in atherosclerosis: Mechanisms, disease progression and therapeutic potential (Review).

Atherosclerosis is a chronic and progressive vascular disease involving the gradual accumulation of lipids, cholesterol, cellular debris, and fibrous elements within the arterial wall. This process leads to the thickening and hardening of arteries, resulting in restricted blood flow and reduced oxygen delivery to tissues. Over time, these pathological changes significantly elevate the risk of life‑threatening cardiovascular events, including myocardial infarction and ischemic stroke.

MoS/TiO p-n-Type Heterojunction as a Photoelectrochemical Biosensor for Detecting Dopamine.

Dopamine is a crucial neurotransmitter associated with neurological regulation and requires precise detection due to its concentration-dependent correlation with neurological disorders. In this work, a novel photoelectrochemical (PEC) sensor based on MoS/TiO nanotubes (MoS/TiO NTs) with p-n heterojunction nanocomposite was prepared through hydrothermal method. The constructed p-n heterojunction effectively enhanced charge separation efficiency, as systematically verified by multidimensional characterization including XRD, SEM, TEM, XPS, EIS, PL, UV-vis, M-S, etc.

The study reveals the catalytic activity of N gas for ethane dehydrogenation.

Phase Separation of Binary Triptycenes by an Iodine Interlayer Film on a Ag(111) Surface.

We report the self-assembly behaviors of two triptycenes (Trip- and Trip-) on metal surfaces without and with an iodine passivation interlayer by combining scanning tunneling microscopy (STM) and density functional theory (DFT) studies. On the Ag(111) surface, Trip- molecules form islands through intermolecular aldehyde-aldehyde hydrogen bonding and π-π stacking of benzene rings. In contrast, Trip- molecules lie flat and dispersed on the surface.

The diagnostic accuracy of preimplantation genetic testing (PGT) in assessing the genetic status of embryos: a systematic review and meta-analysis.

Background: Preimplantation genetic testing (PGT) is widely used in assisted reproduction to assess the genetic status of embryos. However, increasing evidence suggests that the trophectoderm (TE) may not fully reflect the genetic status of the inner cell mass (ICM), raising controversy about the accuracy of TE biopsy. Research in recent years has focused on cell-free DNA (cfDNA) found in blastocoel fluid (BF) and spent culture medium (SCM), as these may contain genetic information from both the TE and ICM.

Stefan-Boltzmann Water Catalyzed Propane Dehydrogenation.

The traditional wisdom of utilizing water in practical olefin synthesis has been viewed as a means to reduce alkane partial pressure and assist in coke removal. However, under such harsh reaction conditions, the potential catalytic role of the water molecule remains unclear. This study explores the intriguing concept that the water molecule, through the selective excitation of molecular vibrations and collisions induced by thermal energy and thermal radiation, could act as a catalyst in homogeneous gaseous propane dehydrogenation.

In Situ Studies on the Influence of Surface Symmetry on the Growth of MoSe Monolayer on Sapphire Using Reflectance Anisotropy Spectroscopy and Differential Reflectance Spectroscopy.

The surface symmetry of the substrate plays an important role in the epitaxial high-quality growth of 2D materials; however, in-depth and in situ studies on these materials during growth are still limited due to the lack of effective in situ monitoring approaches. In this work, taking the growth of MoSe as an example, the distinct growth processes on AlO (112¯0) and AlO (0001) are revealed by parallel monitoring using in situ reflectance anisotropy spectroscopy (RAS) and differential reflectance spectroscopy (DRS), respectively, highlighting the dominant role of the surface symmetry. In our previous study, we found that the RAS signal of MoSe grown on AlO (112¯0) initially increased and decreased ultimately to the magnitude of bare AlO (112¯0) when the first layer of MoSe was fully merged, which is herein verified by the complementary DRS measurement that is directly related to the film coverage.

Characterize and Mediate Assembly of Triptycenes on Au(111) Surface.

Herein, we report the assembly behavior of triptycenes with aldehyde (Trip-) and amino (Trip-) groups on pristine and iodine-passivated Au(111) surfaces by a combination of scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and density functional theory (DFT) calculation. On Au(111) surface, Trip- forms long trimer chains and two-dimensional islands via aldehyde-aldehyde hydrogen bonding in one dimension and π-π stacking of adjacent benzene rings in the other dimension. In contrast, Trip- lies as individuals or in disorderly stacked islands.

Persulfate-based advanced oxidation processes (PS-AOPs) have been widely investigated by academia and industry due to their high efficiency and selectivity for the removal of trace organic pollutants from complex water substrates. PS-AOPs have been extensively studied for the degradation of pesticides, drugs, halogen compounds, dyes, and other pollutants. Utilizing bibliometric statistics, this review presents a comprehensive overview of persulfate-based advanced oxidation technology research over the past decade.

Two laser-assisted hatching methods of embryos in ART: a systematic review and meta-analysis.

Background: Laser-assisted hatching (LAH) stands as the predominant technique for removing the zona pellucida (ZP) in embryos, primarily consisting of two methods: drilling laser-assisted hatching (D-LAH) and thinning laser-assisted hatching (T-LAH). Presently, both methods have limitations, and their comparative efficacy for embryo implantation and clinical pregnancy remains uncertain.

Aim: Evaluate the impact of D-LAH and T-LAH on clinical pregnancy rates within assisted reproductive technology (ART).

The contamination of drinking water by microbes is a critical health concern, underscoring the need for safe, reliable, and efficient methods to treat pathogenic microorganisms. While most sterilization materials are available in powder form, this presents safety risks and challenges in recycling. Herein, this study reports the preparation of an innovative copper oxide supported silver monolithic nanoarray mesh with abundant oxygen vacancies (Ag/CuO-V) by laser ablation.

The Comparison of Two Whole-Genome Amplification Approaches for Noninvasive Preimplantation Genetic Testing (ni-PGT) and the Application Scenario of ni-PGT during the Fresh Cycle.

Recently, noninvasive preimplantation genetic testing (ni-PGT) using degenerate oligonucleotide primer PCR (DOP-PCR) and multiple annealing and looping-based amplification cycle (MALBAC)-based whole-genome amplification (WGA) methods has demonstrated predictable results in embryo testing. However, a considerable heterogeneity of results has been reported in numerous studies on these two WGA methods. Our aim was to evaluate the current WGA method for ni-PGT while further clarifying the applicable scenarios of ni-PGT in the fresh cycle.

Discovery and construction of surface kagome electronic states induced by p-d electronic hybridization in CoSnS.

Kagome-lattice materials possess attractive properties for quantum computing applications, but their synthesis remains challenging. Herein, based on the compelling identification of the two cleavable surfaces of CoSnS, we show surface kagome electronic states (SKESs) on a Sn-terminated triangular CoSnS surface. Such SKESs are imprinted by vertical p-d electronic hybridization between the surface Sn (subsurface S) atoms and the buried Co kagome-lattice network in the CoSn layer under the surface.

[Progress of research on chromosomal mosaicism embryos].

Chromosomal mosaicism (CM) is a common phenomenon in preimplantation genetic testing (PGT). In embryos with CM, genetic contents of trophoblastic ectodermal (TE) cells may be different from that of the inner cell mass (ICM) which will develop into the fetus. Embryos with low mosaic proportion could give rise to healthy live births after transplantation, but are accompanied with high pregnancy risks such as high abortion rate.

The inhibition of p38 MAPK blocked inflammation to restore the functions of rat meibomian gland epithelial cells.

Meibomian glands (MGs) are vital for ocular surface health. However, the roles of inflammation in the progression of meibomian gland dysfunction (MGD) are largely unknown. In this study, the roles of the inflammation factor interleukin-1β (IL-1β) via the p38 mitogen-activated protein kinases (MAPK) signaling pathway on rat meibomian gland epithelial cells (RMGECs) were explored.

Surface Characterization of the Solution-Processed Organic-Inorganic Hybrid Perovskite Thin Films.

The surface properties of organic-inorganic hybrid perovskites can strongly affect the efficiency and stability of corresponding devices. Even though different surface passivation methods are developed, the microscopic structures of solution-processed perovskite film surfaces are not systematically studied. This study uses low-temperature scanning tunneling microscopy to study the organic-inorganic hybrid perovskite thin films, MA FA PbI and MAPbI , synthesized by the spin-coating method.

Desilylative Coupling Involving C(sp)-Si Bond Cleavage on Metal Surfaces.

Desilylative coupling involving C-Si bond cleavage has emerged as one of the most important synthetic strategies for carbon-carbon/heteroatom bond formation in solution chemistry. However, in on-surface chemistry, C-Si bond cleavage remains a synthetic challenge. Here, we report the implementation of C(sp)-Si bond cleavage and subsequent C-C bond formation on metal surfaces.

Multiple 2D Phase Transformations in Monolayer Transition Metal Chalcogenides.

Phase transformation lies at the heart of materials science because it allows for the control of structural phases of solids with desired properties. It has long been a challenge to manipulate phase transformations in crystals at the nanoscale with designed interfaces and compositions. Here in situ electron microscopy is employed to fabricate novel 2D phases with different stoichiometries in monolayer MoS and MoSe .

Tissue-Engineered Corneal Endothelial Sheets Using Ultrathin Acellular Porcine Corneal Stroma Substrates for Endothelial Keratoplasty.

Tissue-engineered cornea endothelial sheets (TECES), created using a biocompatible thin and transparent carrier with corneal endothelial cells, could alleviate the shortage of donor corneas and provide abundant functional endothelial cells. In our previous clinical trials, the effectiveness and safety of the acellular porcine corneal stroma (APCS) applied in lamellar keratoplasty have been confirmed. In this study, we optimized the method to cut APCS into multiple 20 μm ultrathin lamellae by a cryostat microtome and investigated the feasibility of TECES by seeding rabbit corneal endothelial cells (RCECs) on ultrathin APCS.

Processes and mechanisms of phosphorus mobility among sediment, water, and cyanobacteria under hydrodynamic conditions.

Phosphorus (P) has an important role in eutrophication and it is essential to explore the processes and mechanisms of P mobility in natural waters. In this study, laboratory experiments were conducted to simulate the SW system (sediment and water) and SAW system (sediment, algae, and water) under four hydrodynamic intensity conditions (static control, 50 rpm, 125 rpm, and 200 rpm treatments), to investigate P mobility. Results in SW system showed that sediment was an important source of P for overlying water, and the released total P (TP) increased with stronger hydrodynamic intensity, when P associated with metal pools (redox-sensitive P [BD-P] and meta-oxides bound P [NaOH-P]) were the most unstable and easier to migrate into the overlying water.

Benchmarking atomically defined AFM tips for chemical-selective imaging.

Controlling the identity of the tip-terminating atom or molecule in low-temperature atomic force microscopy has led to ground breaking progress in surface chemistry and nanotechnology. Lacking a comparative tip-performance assessment, a profound standardization in such experiments is highly desirable. Here we directly compare the imaging and force-spectroscopy capabilities of four atomically defined tips, namely Cu-, Xe-, CO-, and O-terminated Cu-tips (CuOx-tips).
