Follicular fluid extracellular vesicles are beneficial for in vitro oocyte maturation and development; however, their effect on the expression profiles of oocyte microRNAs (miRNAs) and the roles of related miRNAs are unknown. In this study, we aimed to investigate miRNA expression in mature oocytes cultured in follicular fluid extracellular vesicles and the effect of miRNA-125a (miR-125a) on oocyte maturation. The expression profiles of the miRNAs were determined by microRNA sequencing, followed by target gene prediction analysis.

Herein, we designed a 2D multilayered MXene TiCT adsorbent for selective extraction of REEs in a broad pH range.

Herein, we overcome this challenge by constructing the NiFe hydroxide/NiMo alloy (NiFe-LDH/NiMo) heterojunction electrocatalyst, featuring the NiMo alloy as the oxygen pump to provide oxygenous intermediates and electrons for NiFe-LDH. The released lattice oxygen can be timely offset by the oxygenous species during the LOM process, balancing the regeneration of lattice oxygen and assuring the enhancement of the durability.

However, the unsatisfactory activation ability of Pd-based alloys toward O molecules limits further improvement of ORR kinetics. Herein, the precise synthesis of nanosheet assemblies of spin-polarized PdCu-FeO in-plane heterostructures for drastically activating O molecules and boosting ORR kinetics is reported.

In such cases, the acoustic signals emitted by these vessels often overlap, causing interference and reducing the accuracy of vessel identification. This paper proposes an improved GALR end-to-end underwater acoustic source separation algorithm, with ECA-DE (Efficient Channel Attention-Deep Encoder) and Bi-GRU (Bidirectional Gated Recurrent Unit), which consists of an encoder, separation blocks, and a decoder (EDBG-GALR).

However, this strategy has been limited to the use of nucleic acids as templating elements to direct the proximity effect. Herein, we describe a versatile rotein-emplated lit ptamer lick igation eaction (PT-SpA-CLR) in which the protein template-induced covalent proximity ligation of split aptamer elements enables translating protein/aptamer binding events into the output of ligated DNA products.

Current noise reduction algorithms based on non-negative matrix factorization (NMF) typically utilize the Euclidean distance as their objective function, which can exacerbate noise anomalies. Moreover, these algorithms predominantly rely on simple techniques like Wiener filtering to estimate the amplitude spectrum of pure signals.

In this work, we synthesized a heterogeneous CuO nanocatalyst (hnCuO) with different particle sizes and shapes, which was used for developing enzyme- and label-free nucleic acid amplification methods based on the nucleic acid-templated azide-alkyne cycloaddition (AAC) reaction catalyzed by hnCuO. The hnCuO exhibited size- and shape-dependent catalytic activity, with smaller sizes and spherical-like shapes exhibiting superior activity.

There have been few studies on the regulatory influence of the 9 gene on the differentiation of chicken embryonic stem cells (cESCs) into male germ cells, and the significance of 9 is still unknown. Therefore, we explored the specific role of 9 during differentiation of the cESCs of Jilin Luhua chickens through inhibition or overexpression.

Osteoarthritis (OA) is a common joint disorder affecting about 7% of the global population, primarily characterized by the gradual loss of articular cartilage. This degeneration results from local inflammation, matrix depletion, and direct cartilage damage. A critical element in this process is the activation of the stimulator of the interferon genes (STING) pathway.

However, rapid, cost-efficient, and ultrasensitive identification of nucleic acid targets still represents a significant challenge.

In this study, we investigated the potential role of EF-hand domain family member D2 (EFHD2), a novel molecule specific to immune cells, in the pathogenesis of NASH.
Methods: Hepatic EFHD2 expression was characterized in patients with NASH and two diet-induced NASH mouse models.
As an ideal drug carrier, it should possess high drug loading and encapsulation efficiency and precise drug targeting release. Herein, we utilized a template-guided self-weaving technology of phase-separated silk fibroin (SF) in reverse microemulsion (RME) to fabricate a kind of hyaluronic acid (HA) coated SF nanocage (HA-gNCs) for drug delivery of cancer immunotherapy. Due to the hollow structure, HA-gNCs were capable of simultaneous encapsulation of the anti-inflammatory drug betamethasone phosphate (BetP) and the immune checkpoint blockade (ICB) agent PD-L1 antibody (αPD-L1) efficiently.

Recurrent miscarriage (RM) seriously affects the physical and mental health of women of childbearing age, and 50% of the causes are unknown. Thus, it is valuable to investigate the causes of unexplained recurrent miscarriage (uRM). Similarities between tumor development and embryo implantation make us realize that tumor studies are informative for uRM.

Herein, based on the common polymeric carbon nitride (PCN), a hybrid co-catalysts system comprising plasmonic Au nanoparticles (NPs) and atomically dispersed Pt single atoms (PtSAs) with different functions was constructed to address this challenge. For the dual co-catalysts decorated PCN (PtSAs-Au/PCN), the PCN is photoexcited to generate electrons under UV and short-wavelength visible light, and the synergetic Au NPs and PtSAs not only accelerate charge separation and transfer though Schottky junctions and metal-support bond but also act as the co-catalysts for H evolution.
