Herein, MOF-confined ultrafine ZnIrO clusters (ZnIrO/ZnIrMOFs) nanozyme have been synthesized by controlling the in-situ growth of ZnIrO via a one-pot method. Notably, due to the domain-limiting effect of MOF, the ZnIrO clusters with small size grew uniformly in the structure of ZnIrMOFs nanosheets, while the presence of Zn atoms improved the crystallinity of the MOF phase and the dispersion of ZnIrO clusters.

In recent years, microchannel fabrication technology based on hot embossing has attracted considerable attention due to its convenience and low cost. A new evaluation method of microchannels, as well as an approach to obtaining optimal hot embossing conditions based on the Taguchi method, is proposed in this paper to fabricate precise microchannels for a flexible proton-exchange membrane fuel cell (PEMFC).

Objective: To explore the association between polymorphisms of transforming growth factor-β (TGF-β) signaling pathway and non-syndromic cleft lip with or without cleft palate (NSCL/P) among Asian populations, while considering gene-gene interaction and gene-environment interaction.
Methods: A total of 1 038 Asian NSCL/P case-parent trios were ascertained from an international consortium, which conducted a genome-wide association study using a case-parent trio design to investigate the genes affec-ting risk to NSCL/P. After stringent quality control measures, 343 single nucleotide polymorphism (SNP) spanning across 10 pivotal genes in the TGF-β signaling pathway were selected from the original genome-wide association study(GWAS) dataset for further analysis.
This study presents a numerical simulation-based investigation of a MEMS (micro-electromechanical systems)technology-based deformable mirror employing a piezoelectric film for fundus examination in adaptive optics. Compared to the classical equal-area electrode arrangement model, we optimize the electrode array for higher-order aberrations. The optimized model centralizes electrodes around the mirror center, which realizes low-voltage driving with high-accuracy correction.

Nevertheless, the poor intrinsic properties of 2H-MoS limit its electrocatalytic performances toward HER. In this work, graphitic carbon nitride covalently bridging 2H-MoS (MoS/GCN) is proposed to construct robust HER electrocatalysts.

Heat stress is an increasingly significant abiotic stress factor affecting crop yield and quality. This study aims to uncover the regulatory mechanism of sweet corn response to heat stress by integrating transcriptome and metabolome analyses of seedlings exposed to normal (25 °C) or high temperature (42 °C). The transcriptome results revealed numerous pathways affected by heat stress, especially those related to phenylpropanoid processes and photosynthesis, with 102 and 107 differentially expressed genes (DEGs) identified, respectively, and mostly down-regulated in expression.
View Article and Find Full Text PDFFlexible electronic sensors show great potential for health monitoring but are usually limited to single sensing functionality. To enrich their functions, complicated device configurations, sophisticated material systems, and preparation processes are typically involved, obstructing their large-scale deployment and widespread application. Herein, to achieve a good balance between simplicity and multifunctionality, a new paradigm of sensor modality for both mechanical sensing and bioelectrical sensing is presented based on a single material system and a simple solution processing approach.

Intriguingly, these miRNAs are predominantly expressed in the testis, suggesting a potential role in spermatogenesis and male fertility. Here, we report that the X-linked family miRNAs were derived from the MER91C DNA transposons.
View Article and Find Full Text PDFNatural tactile sensation is complex, which involves not only contact force intensity detection but also the perception of the force direction, the surface texture, and other mechanical parameters. Nevertheless, the vast majority of the developed tactile sensors can only detect the normal force, but usually cannot resolve shear force or even distinguish the directions of the force. Here, we present a new paradigm of bioinspired tactile sensors for resolving both the intensity and the directions of mechanical stimulations via synergistic microcrack-bristle structure design and cross-shaped configuration engineering.

View Article and Find Full Text PDFReports that mouse sperm gain small RNAs from the epididymosomes secreted by epididymal epithelial cells and that these "foreign" small RNAs act as an epigenetic information carrier mediating the transmission of acquired paternal traits have drawn great attention because the findings suggest that heritable information can flow from soma to germ line, thus invalidating the long-standing Weismann's barrier theory on heritable information flow. Using small RNA sequencing (sRNA-seq), northern blots, sRNA in situ hybridization, and immunofluorescence, we detected substantial changes in the small RNA profile in murine caput epididymal sperm (sperm in the head of the epididymis), and we further determined that the changes resulted from sperm exchanging small RNAs, mainly tsRNAs and rsRNAs, with cytoplasmic droplets rather than the epididymosomes. Moreover, the murine sperm-borne small RNAs were mainly derived from the nuclear small RNAs in late spermatids.

In this study, we discovered an ELMO domain-containing 3 (ELMOD3), which belongs to ADP-ribosylation factor GTPase-activating protein family, was necessary to form the notochord lumen in larvae We demonstrated that ELMOD3 interacted with lipid raft protein Flotillin2 and regulated its subcellular localization. The loss-of-function of Flotillin2 prevented notochord lumen formation.
