Composite solid electrolytes (CSEs) possess significant advantages over individual polymer or inorganic solid electrolytes. However, conventional CSEs suffer from multiple scale issues, including interruptions in ionic transport pathways, incompatibility at heterogeneous interface, and the excessive thickness of electrolytes. Herein, a novel CSE with ultrathin structure (22 µm) based on the strategy of multiscale collaborative optimization (MC-CSE) is designed.

Oocyte quality can affect mammal fertilization rate, early embryonic development, pregnancy maintenance, and fetal development. Oxidative stress induced by reactive oxygen species (ROS) is one of the most important causes of poor oocyte maturation in vitro. To reduce the degree of cellular damage caused by ROS, supplementation with the antioxidant N-Acetyl-L-cysteine (NAC) serves as an effective pathway to alleviate glutathione (GSH) depletion during oxidative stress.

Organoids, self-organized structures derived from stem cells cultured in a specific three-dimensional (3D) microenvironment, have emerged as innovative platforms that closely mimic cellular behavior, tissue architecture, and organ function. Bone organoids, a frontier in organoid research, can replicate the complex structures and functional characteristics of bone tissue. Recent advancements have led to the successful development of bone organoids, including models of callus, woven bone, cartilage, trabecular bone, and bone marrow.

Mechanical force is essential for bone development, bone homeostasis, and bone fracture healing. In the past few decades, various biomaterials have been developed to provide mechanical signals that mimic the natural bone microenvironment, thereby promoting bone regeneration. Bone organoids, emerging as a novel research approach, are 3D micro-bone tissues that possess the ability to self-renew and self-organize, exhibiting biomimetic spatial characteristics.

Article Synopsis
  • - Bone organoids are being developed to study bone growth and diseases, but current methods often fall short because they create simplistic structures that don't mimic real bone well or allow for proper mineralization.
  • - A new approach using 3D printing and a bioink made from bone marrow-derived stem cells aims to create more complex and functional bone structures, which can form bone tissue independently when implanted into mice.
  • - This innovative bone organoid model provides a valuable new platform for researchers to investigate bone development, test therapies, and understand congenital conditions more effectively.

During cryopreservation, spermatozoa produce excess reactive oxygen species (ROS), which attack the plasma membrane, disrupt the physiological structure of the sperm, and ultimately decrease semen quality. This study investigated the effects of different N-acetylcysteine (NAC) concentrations on the cryopreservation of semen from Qianbei Ma goats. Semen samples were collected from five bucks with motility rates above 80 %.

  • * Using data from 59 cities in China's Yellow River Basin from 2004 to 2021, the study modifies traditional carbon accounting models to assess the distribution and impact of ecocompensation credits across regions.
  • * The findings reveal that while ecocompensation credits show patterns of agglomeration, their distribution is uneven; the effectiveness of green technology emerges as the main factor influencing these changes, providing insights for ongoing and future ecocompensation policies.

Organoids are "mini-organs" that self-organize and differentiate from stem cells under in vitro 3D culture conditions, mimicking the spatial structure and function of tissues in vivo. Extracellular vesicles (EVs) are nanoscale phospholipid bilayer vesicles secreted by living cells, rich in bioactive molecules, with excellent biocompatibility and low immunogenicity. Compared to EVs, organoid-derived EVs (OEVs) exhibit higher yield and enhanced biological functions.

Article Synopsis
  • Ultrasound is vital for hepatobiliary surgeons to visualize complex anatomy, but converting 2D images to 3D can be challenging, necessitating better tools for real-time anatomical identification.
  • A new augmented reality (AR) system uses advanced techniques like backward alpha blending and spatial smoothing to create real-time 3D visualizations from 2D ultrasound data, improving how surgeons interpret the images.
  • Experiments show that this AR method significantly lowers operational times and enhances depth perception while boosting user satisfaction, indicating its strong potential for improving surgical accuracy and decision-making.

Reproductive traits are vital economic parameters in goat production, and boosting the reproductive capacity of breeding rams is crucial for enhancing the profitability of goat farming. Currently, research on the reproductive performance of Qianbei Ma goats mainly centers on investigating mechanisms associated with prolificacy and estrous ovulation in ewes, with limited emphasis on ram reproductive aspects. This study used scanning electron microscopy and enzyme-linked immunosorbent assay (ELISA) to profile the morphology of testis and the dynamic changes of Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), and Testosterone (T) in serum at different developmental stages of Qianbei Ma goats.

The expression pattern of in the testis and its regulatory effect on testicular cells was explored in goats to enhance our understanding of spermatogenesis and improve reproduction in breeding rams. In this study, we demonstrated the localization of in testicular cells using immunohistochemistry and subcellular localization analyses. Subsequently, we analyzed the expression pattern in four age-based groups (0, 6, 12, and 18 months old) using real-time quantitative polymerase chain reaction (qRT-PCR) and protein blotting.

Although previous studies have shown that repetitive transcranial magnetic stimulation (rTMS) can ameliorate addictive behaviors and cravings, the underlying neural mechanisms remain unclear. This study aimed to investigate the effect of high-frequency rTMS with the left dorsolateral prefrontal cortex (L-DLPFC) as a target region on smoking addiction in nicotine-dependent individuals by detecting the change of spontaneous brain activity in the reward circuitry. We recruited 17 nicotine-dependence participants, who completed 10 sessions of 10 Hz rTMS over a 2-week period and underwent evaluation of several dependence-related scales, and resting-state fMRI scan before and after the treatment.

The need to select mediators from a high dimensional data source, such as neuroimaging data and genetic data, arises in much scientific research. In this work, we formulate a multiple-hypothesis testing framework for mediator selection from a high-dimensional candidate set, and propose a method, which extends the recent development in false discovery rate (FDR)-controlled variable selection with knockoff to select mediators with FDR control. We show that the proposed method and algorithm achieved finite sample FDR control.

The addition of the -linked -acetylglucosamine (-GlcNAc) is a significant modification for active molecules, such as proteins, carbohydrates, and natural products. However, the synthesis of terpenoid glycoside derivatives decorated with GlcNAc remains a challenging task due to the absence of glycosyltransferases, key enzymes for catalyzing the transfer of GlcNAc to terpenoids. In this study, we demonstrated that the enzyme mutant UGT74AC1 efficiently transferred GlcNAc from uridine diphosphate (UDP)-GlcNAc to a variety of terpenoids.

Heat dissipation plays a crucial role in the performance and reliability of high-power GaN-based electronics. While AlN transition layers are commonly employed in the heteroepitaxial growth of GaN-on-SiC substrates, concerns have been raised about their impact on thermal transport across GaN/SiC interfaces. In this study, we present experimental measurements of the thermal boundary conductance (TBC) across GaN/SiC interfaces with varying thicknesses of the AlN transition layer (ranging from 0 to 73 nm) at different temperatures.

The rendering of specular highlights is a critical aspect of 3D rendering on autostereoscopic displays. However, the conventional highlight rendering techniques on autostereoscopic displays result in depth conflicts between highlights and diffuse surfaces. To address this issue, we propose a viewpoint-dependent highlight depiction method with head tracking, which incorporates microdisparity of highlights in binocular parallax and preserves the motion parallax of highlights.
