The primary role of the gastrointestinal tract in broiler chickens is nutrient assimilation, with transporter proteins facilitating the uptake of amino acids, peptides, monosaccharides, fatty acids, and minerals across the intestinal epithelium. Among these nutrient transporters, members of the solute carrier family are particularly important, and gene expression analyses targeting these transporters have provided informative insights into how birds adapt to diverse dietary, environmental, and physiological challenges to maintain nutrient homeostasis. These transporters are expressed either at the brush border membrane, where they facilitate the absorption of nutrients from the gut lumen into enterocytes, or at the basolateral membrane, where they mediate the transfer of nutrients from the enterocytes into the bloodstream. The expression of these transporters is influenced by a range of factors, including bird age, sex, intestinal segment, dietary substrate availability and source, as well as external stressors such as heat stress and pathogen exposure. While upregulation of transporter genes often suggests an enhanced capacity for nutrient uptake, it does not always correlate with improved growth performance, due to compensatory physiological responses and fluctuations in nutrient bioavailability. Understanding the regulation and functional dynamics of nutrient transporters presents valuable opportunities to develop targeted dietary and management strategies aimed at optimizing nutrient utilization and improving bird performance. This review summarizes current knowledge on the classification, function, and regulation of key nutrient transporters in broilers, highlights factors influencing their expression, and explores their implications for nutrition and production efficiency.

肉鸡胃肠道的主要作用是营养物质的同化,转运蛋白促进氨基酸、多肽、单糖、脂肪酸和矿物质通过肠上皮的吸收。在这些营养转运蛋白中,溶质转运蛋白家族的成员尤为重要,针对这些转运蛋白的基因表达分析为了解鸟类如何适应不同的饮食、环境和生理挑战以维持营养稳态提供了信息。这些转运蛋白要么在刷状边界膜上表达,在那里它们促进营养物质从肠腔吸收到肠细胞,要么在基底外膜上表达,在那里它们介导营养物质从肠细胞转移到血液中。这些转运蛋白的表达受到一系列因素的影响,包括鸟类的年龄、性别、肠道段、膳食底物的可利用性和来源,以及热应激和病原体暴露等外部应激源。虽然转运体基因的上调通常表明营养摄取能力的增强,但由于补偿性生理反应和营养生物利用度的波动,它并不总是与生长性能的改善相关。了解营养转运体的调节和功能动态为制定有针对性的饮食和管理策略提供了宝贵的机会,旨在优化营养利用和提高鸟类生产性能。本文综述了肉鸡主要营养转运蛋白的分类、功能和调控,重点介绍了影响其表达的因素,并探讨了其对营养和生产效率的影响。

Lanthanide-doped upconversion nanoparticles enable upconversion stimulated emission depletion microscopy with high photostability and low-intensity near-infrared continuous-wave lasers. Controlling energy transfer dynamics in these nanoparticles is crucial for super-resolution microscopy with minimal laser intensities and high photon budgets. However, traditional methods neglect the spatial distribution of lanthanide ions and its effect on energy transfer dynamics. Here, we introduce topology-driven energy transfer networks in lanthanide-doped upconversion nanoparticles for upconversion stimulated emission depletion microscopy with reduced laser intensities, maintaining a high photon budget. Spatial separation of Yb3+ sensitizers and Tm3+ emitters in 50-nm core-shell nanoparticles enhance energy transfer dynamics for super-resolution microscopy. Topology-dependent energy migration produces strong 450-nm upconversion luminescence under low-power 980-nm excitation. Enhanced cross-relaxation improves optical switching efficiency, achieving a saturation intensity of 0.06 MW cm-2 under excitation at 980 nm and depletion at 808 nm. Super-resolution imaging with a 65-nm lateral resolution is achieved using intensities of 0.03 MW cm-2 for a Gaussian-shaped excitation laser at 980 nm and 1 MW cm-2 for a donut-shaped depletion laser at 808 nm, representing a 10-fold reduction in excitation intensity and a 3-fold reduction in depletion intensity compared to conventional methods. These findings demonstrate the potential of harnessing topology-dependent energy transfer dynamics in upconversion nanoparticles for advancing low-power super-resolution applications.
镧系掺杂上转换纳米粒子使上转换受激发射耗尽显微镜具有高光稳定性和低强度近红外连续波激光器。控制这些纳米颗粒中的能量传递动力学对于具有最小激光强度和高光子预算的超分辨率显微镜至关重要。然而,传统方法忽略了镧系离子的空间分布及其对能量传递动力学的影响。在这里,我们在镧掺杂的上转换纳米颗粒中引入了拓扑驱动的能量转移网络,用于降低激光强度的上转换受激发射耗尽显微镜,保持高光子预算。50nm核壳纳米颗粒中Yb3+敏化剂和Tm3+发射体的空间分离增强了超分辨显微镜的能量传递动力学。拓扑相关的能量迁移在低功率980纳米激发下产生强大的450纳米上转换发光。增强的交叉弛豫提高了光开关效率,在980 nm激发和808 nm耗尽下达到0.06 MW cm-2的饱和强度。采用0.03 MW cm-2强度的980 nm高斯形激发激光器和1 MW cm-2强度的808 nm环形耗尽激光器,实现了65 nm横向分辨率的超分辨率成像,与传统方法相比,激发强度降低了10倍,耗尽强度降低了3倍。这些发现证明了利用上转换纳米颗粒中拓扑相关的能量传递动力学来推进低功耗超分辨率应用的潜力。

Skeletal muscle accounts for approximately 40% of body mass and 50%-75% of whole-body protein, playing a central role in meat production and quality. Efficient protein synthesis in skeletal muscle relies on an adequate supply of nutrient substrates and a balanced amino acid profile. Branched-chain amino acids (BCAA), including leucine (Leu), isoleucine (Ile), and valine (Val), are the most abundant essential amino acids in skeletal muscle and contribute to both protein synthesis and oxidative energy production. Additionally, BCAA function as signaling molecules that regulate gene expression and protein phosphorylation cascades, which significantly influence physiological processes, such as protein synthesis and degradation, glucose and lipid metabolism, and cell apoptosis and autophagy. These processes are primarily mediated through the PI3K/AKT/AMPK/mTOR signaling pathways. This review summarizes BCAA transporters and catabolic metabolism, their role as signaling molecules in regulating protein metabolism and glucose and lipid equilibrium, and applications in animal production. These findings offer both theoretical insights and practical guidelines for the precise regulation of feed efficiency and production performance through tailored dietary BCAA supplementations.

骨骼肌约占体重的40%,占全身蛋白质的50%-75%,在肉类生产和质量中起着核心作用。骨骼肌中有效的蛋白质合成依赖于充足的营养基质供应和平衡的氨基酸结构。支链氨基酸(BCAA),包括亮氨酸(Leu)、异亮氨酸(Ile)和缬氨酸(Val),是骨骼肌中最丰富的必需氨基酸,有助于蛋白质合成和氧化能的产生。此外,BCAA作为调节基因表达和蛋白磷酸化级联反应的信号分子,显著影响蛋白质合成和降解、糖脂代谢、细胞凋亡和自噬等生理过程。这些过程主要通过PI3K/AKT/AMPK/mTOR信号通路介导。本文综述了BCAA转运体与分解代谢、BCAA转运体作为信号分子在调节蛋白质代谢和糖脂平衡中的作用及其在动物生产中的应用。这些发现为精准调控饲料效率和生产性能提供了理论见解和实践指导。

Background: Low dietary energy levels can disrupt energy balance, causing metabolic disorders, particularly those involving in hepatic lipid metabolism. Betaine (BET), an important methyl donor, has demonstrated protective effects against liver diseases. However, its effects on hepatic lipid metabolism in pigs fed a low-net energy (NE) diet and the underlying mechanisms remain unclear. Thirty-two pigs (85.52 ± 2.27 kg) were randomly assigned to four treatments: N-NE group (normal NE diet, 2,475 kcal/kg NE), N-NEB group (normal NE diet + 1,500 mg/kg BET, 2,475 kcal/kg NE), R100-NE group (low-NE diet, 2,375 kcal/kg NE), and R100-NEB group (low-NE diet + 1,500 mg/kg BET, 2,375 kcal/kg NE). The experiment lasted 35 d.

Results: There was no significant difference in growth performance among the groups (P > 0.05). Reducing dietary NE levels caused liver dysfunction and increased total glyceride concentration, accompanied by lipid metabolism disorders. BET supplementation in a low-NE diet exhibited hepatoprotective roles, as evidenced by increased TP concentration and reduced ALT level in serum (P < 0.05), as well as decreased fat content, adipocyte size, and total glyceride concentration in the liver (P < 0.05). Meanwhile, dietary BET alleviated low-NE diet-induced hepatic lipid metabolism disorder by downregulating mRNA expressions of genes related to fatty acid transport (FABP3 and CD36) and lipogenesis (SREBP1c and FASN), while upregulating mRNA expressions involved in lipolysis (CPT1 and HSL) (P < 0.05). Furthermore, dietary BET increased serum SAM concentration and the SAM/SAH ratio in pigs fed low-NE diets (P < 0.05), thereby providing sufficient methyl groups through regulating the activities of enzymes participated in BET metabolism. Mechanistically, BET increased m6A modification level and regulated mRNA and protein expressions of m6A modified proteins including METTL3, METTL14, WTAP, YTHDF1, and ALKBH5. Correlation analysis showed a significant association between m6A RNA methylation and hepatic lipid metabolism, suggesting that m6A RNA methylation may play a critical role in mediating hepatic lipid metabolism.

Conclusions: Dietary BET supplementation in low-NE diets alleviated hepatic lipid metabolism disorders by regulating m6A RNA methylation, ultimately reducing hepatic lipid accumulation in finishing pigs.

背景:低饮食能量水平会破坏能量平衡,引起代谢紊乱,特别是与肝脂质代谢有关的代谢紊乱。甜菜碱(BET)是一种重要的甲基供体,对肝脏疾病具有保护作用。然而,其对低净能(NE)饲粮猪肝脂代谢的影响及其潜在机制尚不清楚。试验选用32头体重为85.52±2.27 kg的猪,随机分为4个处理:N-NE组(正常NE饲粮,2,475 kcal/kg NE)、N-NEB组(正常NE饲粮+ 1,500 mg/kg BET, 2,475 kcal/kg NE)、R100-NE组(低NE饲粮,2,375 kcal/kg NE)和R100-NEB组(低NE饲粮+ 1,500 mg/kg BET, 2,375 kcal/kg NE)。试验期35 d。结果:各组间生长性能无显著差异(P < 0.05)。降低膳食NE水平可引起肝功能障碍和总甘油浓度升高,并伴有脂质代谢紊乱。在低ne日粮中添加BET具有肝脏保护作用,这可以通过提高血清TP浓度和降低ALT水平(p6a修饰水平)以及调节m6A修饰蛋白(包括METTL3、METTL14、WTAP、YTHDF1和ALKBH5)的mRNA和蛋白表达来证明。相关分析显示,m6A RNA甲基化与肝脏脂质代谢存在显著相关性,提示m6A RNA甲基化可能在介导肝脏脂质代谢中发挥关键作用。结论:在低ne饲粮中添加BET可通过调节m6A RNA甲基化来缓解肥育猪肝脏脂质代谢紊乱,最终减少肝脏脂质积累。

Electrochemical CO2 reduction has been considered a promising approach to neutralizing the global CO2 level. As an intriguing technique, metal-CO2 battery devices can not only capture CO2 into valuable carbonaceous chemicals and reduce the CO2 concentration in the atmosphere but enable energy conversion. Among metal-CO2 batteries, aqueous Zn–CO2 batteries, especially rechargeable systems, exhibit flexible CO2 electrochemistry in terms of multi-carbon chemicals, which are gaseous or water-soluble, in favor of rechargeability and cycling durability of aqueous battery systems. Despite the increasing number of publications on Zn–CO2 batteries in the past three years, this field is still in its beginning stage and facing many challenges considering the capability of CO2 fixation and battery performance. Herein, we present a timely and overall summary of the recent progress in Zn–CO2 batteries, including fundamental mechanisms, affecting factors on electrochemical performance, catalyst cathodes, and electrolytes (catholytes and anolytes). Besides, we assess the application potential of Zn–CO2 batteries and compare this with those of alkali metal-CO2 batteries based on CO2 fixation and battery performance. Finally, we point out some current challenges for the further development of Zn–CO2 batteries and put forward perspectives of the research directions for practical applications of Zn–CO2 batteries in the future.
电化学CO2还原被认为是一种很有前途的中和全球CO2水平的方法。作为一项有趣的技术,金属-二氧化碳电池装置不仅可以将二氧化碳捕获为有价值的碳质化学物质,降低大气中的二氧化碳浓度,还可以实现能量转换。在金属-CO2电池中,水性锌-CO2电池,特别是可充电系统,在气态或水溶性的多碳化学物质方面表现出灵活的CO2电化学,有利于水性电池系统的可充电性和循环耐久性。尽管近三年来关于Zn-CO2电池的文章越来越多,但考虑到CO2固定能力和电池性能,该领域仍处于起步阶段,面临许多挑战。在此,我们及时和全面地总结了锌-二氧化碳电池的最新进展,包括基本机制,电化学性能的影响因素,催化剂阴极和电解质(阴极和阳极)。此外,我们评估了锌-二氧化碳电池的应用潜力,并从二氧化碳固定和电池性能两方面对其与碱金属-二氧化碳电池进行了比较。最后,指出了当前锌- co2电池进一步发展面临的挑战,并对今后锌- co2电池实际应用的研究方向提出了展望。

Photocatalytic conversion of chemical fuels has emerged as a most challenging subject in photocatalysis which is considered as one of the sustainable solutions for environmental issues related to the energy shortage and anthropogenic carbon emissions. Herein, unique heterostructures of ZnCdS nanoplates with Bi2S3−terminated edges were prepared through a facile cation exchange pathway, by which the controlled photocatalytic CO2 conversion was achieved. The optimized BZCS–NS−5 photocatalyst exhibited an excellent capacity of CO2 photoreduction with a CO production rate of ca. 513.2 ​± ​5.1 ​μmol ​g−1 ​h−1 and a selectivity of ca. 91.0%, which were among the highest activities for sulfide photocatalysts documented in the literature. The outstanding photocatalytic performance was attributable to the formation of Z−scheme heterostrucutres between Bi2S3 and ZnCdS, in a way the separation and migration of photocarriers were accelerated. This work thus provides a feasible strategy for the construction of heterostructures to enhance the activity and selectivity of CO2−to−CO conversion via delicate design and controlled synthesis of photocatalysts.
化学燃料的光催化转化已成为光催化领域最具挑战性的课题,被认为是解决能源短缺和人为碳排放等环境问题的可持续解决方案之一。本文通过易阳离子交换途径制备了具有Bi2S3−端部的独特异质结构的ZnCdS纳米板,实现了可控的光催化CO2转化。优化后的BZCS-NS−5光催化剂具有良好的CO2光还原能力,CO产率约为513.2±5.1 μmol g−1 h−1,选择性约为91.0%,是目前文献中活性最高的硫化光催化剂之一。由于Bi2S3与ZnCdS之间形成了Z - scheme异质结构,加速了光载流子的分离和迁移,从而获得了优异的光催化性能。因此,这项工作为构建异质结构提供了一种可行的策略,通过精心设计和控制光催化剂的合成来提高CO2 - to - CO转化的活性和选择性。

Aqueous-electrolyte-based zinc-ion batteries (ZIBs), which have significant advantages over other batteries, including low cost, high safety, high ionic conductivity, and a natural abundance of zinc, have been regarded as a potential alternative to lithium-ion batteries (LIBs). ZIBs still face some critical challenges, however, especially for building a reversible zinc anode. To address the reversibility of zinc anode, great efforts have been made on intrinsic anode engineering and anode interface modification. Less attention has been devoted to the electrolyte additives, however, which could not only significantly improve the reversibility of zinc anode, but also determine the viability and overall performance of ZIBs. This review aims to provide an overview of the two main functions of electrolyte additives, followed by details on six reasons why additives might improve the performance of ZIBs from the perspectives of creating new layers and regulating current plating/stripping processes. Furthermore, the remaining difficulties and potential directions for additives in aqueous ZIBs are also highlighted.
与其他电池相比,基于水电解质的锌离子电池(zib)具有显著的优势,包括低成本、高安全性、高离子电导率和天然丰富的锌,已被视为锂离子电池(lib)的潜在替代品。然而,ZIBs仍然面临着一些关键的挑战,特别是在构建可逆锌阳极方面。为了解决锌阳极的可逆性问题,人们在本征阳极工程和阳极界面改性方面做了大量工作。然而,电解质添加剂不仅能显著提高锌阳极的可逆性,还能决定锌阳极的活力和整体性能,这方面的研究较少。本文综述了电解质添加剂的两种主要功能,并从创建新层和调节电流电镀/剥离工艺的角度详细介绍了添加剂可能改善ZIBs性能的六个原因。此外,还指出了添加剂在水基ZIBs中存在的困难和潜在的发展方向。

The effects of seemingly inert alkali metal (AM) cations on the electrocatalytic activity of electrode materials towards reactions essential for energy provision have become the emphasis of substantial research efforts in recent years. The hydrogen and oxygen evolution reactions during alkaline water electrolysis and the oxygen electro-reduction taking place in fuel cells are of particular importance. There is no universal theory explaining all the details of the AM cation effect in electrocatalysis. For example, it remains unclear how “spectator” AM-cations can change the kinetics of electrocatalytic reactions often more significantly than the modifications of the electrode structure and composition. This situation originates partly from a lack of systematic experimental and theoretical studies of this phenomenon. The present work exploits impedance spectroscopy to investigate the influence of the AM cations on the mechanism of the hydrogen evolution reaction at Pt microelectrodes. The activity follows the trend: Li+≥Na+>K+>Cs+, where the highest activity corresponds to 0.1 ​M LiOH electrolytes at low overpotentials. We demonstrate that the nature of the AM cations also changes the relative contribution of the Volmer–Heyrovsky and Volmer–Tafel mechanisms to the overall reaction, with the former being more important for LiOH electrolytes. Our density functional theory-based thermodynamics and molecular dynamics calculations support these findings.
近年来,看似惰性的碱金属(AM)阳离子对电极材料的电催化活性的影响已成为大量研究工作的重点。在燃料电池中,碱水电解和氧电还原过程中的析氢和析氧反应尤为重要。没有一个通用的理论可以解释电催化中AM阳离子效应的所有细节。例如,目前尚不清楚“旁观者”am -阳离子如何比电极结构和组成的修改更显著地改变电催化反应的动力学。造成这种情况的部分原因是缺乏对这一现象的系统实验和理论研究。本文利用阻抗谱研究了AM阳离子对Pt微电极上析氢反应机理的影响。活性遵循Li+≥Na+>;K+>;Cs+的趋势,其中活性最高的对应于0.1 M的低过电位LiOH电解质。我们证明AM阳离子的性质也改变了Volmer-Heyrovsky和Volmer-Tafel机制对整个反应的相对贡献,其中前者对LiOH电解质更重要。我们基于密度泛函理论的热力学和分子动力学计算支持这些发现。

Owing to the outstanding optoelectronic properties of perovskite materials, perovskite solar cells (PSCs) have been widely studied by academic organizations and industry corporations, with great potential to become the next-generation commercial solar cells. However, critical challenges remain in preserving high efficiency practical large-scale commercialized PSCs: a) the long-term stability of the cell materials and devices, b) lead leakage, and c) methods to scale the cells for larger area applications. This paper summarizes the prior-art strategies to address the above challenges, including the latest studies on the traditional glass-glass and thin-film encapsulation methods to better improve the reliability of PSCs, new technologies for preventing lead leakage, and geometric improvement strategies to enhance the reliability, efficiency, and performance of perovskite solar modules (PSMs). Through these strategies, the device achieved enhanced performance in long-term stability tests. The encapsulation resulted in a high lead leakage inhibition rate of up to 99 ​%, and the PSMs possessed a geometric fill factor of 99.6 ​% and a power conversion efficiency (PCE) of 20.7 ​%. The dramatic improvement of efficiency and reliability of perovskite solar cells and modules indicate the great potential for mass production and commercialization of perovskite solar applications in the near future.

Optical fiber interferometric sensors are of great importance in chemistry, biology, and medicine disciplines owing to high-sensitivity and high-quality factor. However, due to the limitation of free spectral range, the inherent trade-off between wide measurement range and high sensitivity poses a persistent challenge in interference sensor development, which has fundamentally hindered their widespread adoption in precision measurement applications. In this work, a long short-term memory neural network is utilized in a Mach-Zehnder interference-based refractive index sensor to break the free spectral range limitation. Unique gating mechanism in long short-term memory neural network enables it to efficiently process long-term dependent sequence information, such as interference spectrum, avoiding the need for complex spectral signal analysis. A one-to-one mapping relationship is established between the interference spectrum and refractive index with root mean square error of 3.029 × 10-4 and a coefficient of determination of 0.99971. The measurement range is extended from a single free spectral range of 1.3333-1.3561 to approximately three free spectral ranges of 1.3333-1.3921 without sacrificing sensitivity. Moreover, a wider measurement range can be achieved with sufficient training data. This work successfully resolves the inherent contradiction between high sensitivity and wide dynamic measurement range in optical interference-based sensors, opening up a path for the next generation of intelligent sensing systems.
光纤干涉传感器以其高灵敏度和高质量的特性在化学、生物、医学等领域具有重要的应用价值。然而,由于自由光谱范围的限制,宽测量范围和高灵敏度之间的权衡是干扰传感器发展的长期挑战,从根本上阻碍了其在精密测量应用中的广泛应用。在这项工作中,利用长短期记忆神经网络在基于马赫-曾德尔干涉的折射率传感器中打破了自由光谱范围的限制。长短期记忆神经网络独特的门控机制使其能够有效地处理长期依赖的序列信息,如干扰谱,避免了对复杂频谱信号的分析。干涉光谱与折射率之间建立了一一对应关系,均方根误差为3.029 × 10-4,决定系数为0.99971。在不牺牲灵敏度的情况下,测量范围从1.3333-1.3561的单一自由光谱范围扩展到1.3333-1.3921的大约三个自由光谱范围。此外,有足够的训练数据可以实现更大的测量范围。该工作成功地解决了光干涉传感器高灵敏度和宽动态测量范围的固有矛盾,为下一代智能传感系统开辟了道路。
