Functional Ecology, Volume 40, Issue 2, Page 534-552, February 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Non‐structural carbohydrates (NSC) are critical mediators of plant adaptation to fluctuating light environments. They are tightly coordinated with plant economic strategy, that is, leaf economics spectrum (LES) and root economics spectrum (RES).

International Journal of Applied Linguistics, Volume 36, Issue 1, Page 714-724, February 2026.ABSTRACT Interlingual translation, as defined by Roman Jakobson, refers to the transfer of meaning between languages. However, this concept has often been conflated with linguistic shifts between distinct cultures and nation‐states. To challenge this misconception, I propose the concept of self‐consumption translation (SCT), a subfield of interlingual ...

Integrative Conservation, Volume 4, Issue 4, Page 675-685, December 2025.We demonstrated that Anguilla japonica eDNA concentration was allometrically scaled with their body size in both the laboratory and riverine environments. Integrating body size allometry has the potential to improve population abundance estimates in the field, whereas further clarification is required for understanding eDNA production mechanisms ...

Selective Isolation, Identification and Biological Activity Investigation of Rare Actinomycetes from Rhizosphere Soil [PDF]
, 2016 天然产物是新药制备的重要原料，绝大多数来源于微生物的天然产物都分离自放线菌，尤其是链霉菌。链霉菌是放线菌的重要组成成员，能合成结构类型丰富、生物活性多样的次级代谢产物，可用于创制抗生素、抗肿瘤药物、免疫抑制药物、抗虫药物等，在医疗、农业、食品等领域具有重要的应用价值。然而，随着对链霉菌持续的开发利用，目前从链霉菌中发现新型、高活性的次级代谢产物的几率在不断下降，来源于链霉菌的新药研发速度明显放缓。为了解决链霉菌活性次级代谢产物资源日趋枯竭的问题 ...

Optimization of mixed fermentation technology of Lactobacillus helveticus andLactobacillus rhamnosus based on high viable count [PDF]
, 2016 以瑞士乳杆菌和鼠李糖乳杆菌混合发酵培养,利用两菌株细胞代谢的差异,以静置发酵24 h后得到的活菌数目为指标,通过单因素实验和正交实验,研究了瑞士乳杆菌和鼠李糖乳杆菌高活菌数混合发酵的最适发酵条件。结果表明,瑞士乳杆菌和鼠李糖乳杆菌高活菌数混合发酵的最优条件为:发酵温度37℃,初始pH=6.8,接种量6%,瑞士乳杆菌:鼠李糖乳杆菌=1∶2,瑞士乳杆菌优先接种3 h。最终得到乳酸菌总活菌数为7.2×10~9m L~(-1)。与在相同条件下单独发酵的瑞士乳杆菌和鼠李糖乳杆菌活菌数相比,分别提高了1∶8倍和10.

Integrative Conservation, Volume 4, Issue 4, Page 652-664, December 2025.We profiled nutritional and physiological markers in captive sifakas, endangered primates from Madagascar, managed in expansive, non‐native forest enclosures. Variation in many markers reflects freely foraged diets and the energy required to maintain homeostasis under more naturalistic conditions.

浙江大学学报. 医学版睾丸支持细胞在精子发生过程中起重要作用。精子发生的异常与睾丸支持细胞糖脂代谢紊乱密切相关。睾丸支持细胞的代谢环境为缺氧，其主要的代谢方式包括糖酵解和脂肪酸β氧化，其中糖酵解是睾丸支持细胞为生精细胞提供能量的经典途径，而脂肪酸β氧化可能是睾丸支持细胞产生腺苷三磷酸的主要途径。目前睾丸支持细胞糖脂代谢与生精细胞发育的关系、糖代谢与脂代谢之间的联系尚不明确。包括性激素在内的多种激素可以通过调控内分泌影响睾丸支持细胞糖代谢。AMPK、mTOR ...

Integrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

Research on the effect of DHA on glucose metabolism in human lung cancer cells and its anti-tumor mechanism [PDF]
, 2015 研究背景及目的： 肺癌是人类最常见的恶性肿瘤之一，尽管近年来治疗取得了很大进展，治疗效果仍然较差。癌细胞具有偏向通过糖酵解方式来进行糖代谢获得能量的代谢特征使得肿瘤细胞能够比正常细胞具有更强的葡萄糖代谢能力，为肿瘤细胞的快速增殖与生长提供了能量来源，也使其具备更强的凋亡抵抗能力。天然产物凭借其来源广泛、类型多样、不良反应小，具有开发为化疗药物增效减毒辅助药物的潜力等特点备受关注。双氢青蒿素是青蒿叶中分离的有效抗疟成分，体内代谢活性产物为双氢青蒿素。药物学研究证实青蒿素类药物具有抗疟、抗血吸虫 ...
