Plant-based traditional medicines, valued for their diverse biological activities, minimal toxicity, and rich source of immunomodulatory compounds, hold significant cultural and medicinal importance. Within this context, bamboo occupies a prominent position in Asian cultures, both economically and medicinally, having been historically employed to address a range of health issues and demonstrating therapeutic potential against numerous ailments. We undertook a comprehensive analysis of bamboo’s immunomodulatory effects that highlighted significant bioactive components in leaves, shoots, shavings, culms and hemicellulose extracts. These elements enhance immune responses by regulating cytokine levels and cellular defense mechanisms. Notably, bamboo extracts increase TNF-α, IFN-γ, IL-8, and IL-12 levels, showcasing potential applications in immunotherapy and preventive medicine. Beyond immune modulation, bamboo demonstrates anti-inflammatory properties, making it effective in managing conditions such as skin disorders, obesity, and autoimmune diseases. Additionally, bamboo extracts-especially from shoots, leaves, and polysaccharides-exhibit prebiotic activity. They promote the growth of beneficial gut bacteria, including Firmicutes, Bacteroidetes, Proteobacteria and Verrucomicrobia, thereby improving gut health and influencing immune function. The therapeutic benefits of bamboo are due to its diverse phytochemicals, such as polysaccharides, polyphenols (orientin, vitexin, ferulic acid) and phytosterols (stigmasterol, β- sitosterol). These compounds activate host defense mechanisms, regulate immune cells, suppress inflammatory pathways, and influence gene expression suggesting their significant potential in pharmacognosy, particularly for synthesizing nanoparticles in drug delivery and therapeutic applications. Bamboo stands out as a sustainable and versatile natural resource with significant potential in modern medicine. Its multifaceted biological properties offer pathways for developing natural therapeutic products, strengthening its role in advancing healthcare.

以植物为基础的传统药物因其生物活性多样、毒性小、免疫调节化合物来源丰富而受到重视，具有重要的文化和医学意义。在这种背景下，竹子在亚洲文化中占据着突出的地位，无论是在经济上还是在医学上，历史上都被用来解决一系列健康问题，并显示出治疗许多疾病的潜力。我们对竹子的免疫调节作用进行了全面的分析，强调了在叶、芽、刨花、茎和半纤维素提取物中显著的生物活性成分。这些元素通过调节细胞因子水平和细胞防御机制增强免疫反应。值得注意的是，竹提取物可提高TNF-α、IFN-γ、IL-8和IL-12的水平，在免疫治疗和预防医学中具有潜在的应用前景。除了免疫调节外，竹子还具有抗炎特性，可以有效治疗皮肤病、肥胖和自身免疫性疾病。此外，竹子的提取物——尤其是从笋、叶和多糖中提取的——表现出益生元活性。它们促进有益肠道细菌的生长，包括厚壁菌门、拟杆菌门、变形菌门和疣菌门，从而改善肠道健康，影响免疫功能。竹子的治疗作用是由于其多种植物化学物质，如多糖、多酚（东方蛋白、牡荆素、阿魏酸）和植物甾醇（豆甾醇、β-谷甾醇）。这些化合物激活宿主防御机制，调节免疫细胞，抑制炎症通路，并影响基因表达，这表明它们在生药学方面具有重要潜力，特别是在药物输送和治疗应用中合成纳米颗粒。竹子作为一种可持续的、多功能的自然资源，在现代医学中具有巨大的潜力。其多方面的生物学特性为开发天然治疗产品提供了途径，加强了其在推进医疗保健方面的作用。

Bambusa balcooa (Family: Poaceae), synonymous with Arundarbor balcooa, is one of the most robust thick-walled bamboos in the genus Bambusa. Commonly known as Beema bamboo or female bamboo, it is an economically significant species cultivated extensively in tropical regions of Africa, Asia and beyond due to its high income-generating potential. In Northeast India, this edible bamboo is valued for its diverse applications, including biofuel production, paper manufacturing, medicinal uses, pest management and furniture making. The absence of seed production in the species necessitates reliance on vegetative propagation techniques. Among these, micropropagation has emerged as the most effective and reliable technique to meet the growing demand for this species. Our literature search identified various planting media compositions and concentrations for micropropagation. We identified thirty different studies describing different protocols for its successful establishment. Various studies have tried to identify the best composition for culture initiation, multiplication, maintenance and rooting, but pertinent information about acclimatisation and plant survival in the field has rarely been provided, reducing the reproducibility of protocols. We critically analyse optimal protocols for each stage of micropropagation, namely shoot initiation, shoot multiplication, root induction and hardening and highlight opportunities for future research to enhance propagation efficiency. This will contribute to the sustainable propagation and utilisation of B. balcooa, addressing global demands and ecological challenges.

竹科（Bambusa balcooa），与Arundarbor balcooa同义，是竹属中最健壮的厚壁竹之一。通常被称为Beema竹或雌性竹，由于其高创收潜力，它是在非洲，亚洲和其他热带地区广泛种植的经济重要物种。在印度东北部，这种可食用的竹子因其多种用途而受到重视，包括生物燃料生产、造纸、医药用途、害虫管理和家具制造。由于该物种没有种子生产，因此必须依靠无性繁殖技术。其中，微繁技术已成为最有效和可靠的技术，以满足对该物种日益增长的需求。我们的文献检索确定了不同的种植介质组成和浓度。我们确定了30个不同的研究，描述了其成功建立的不同方案。各种研究试图确定培养起始、繁殖、维持和生根的最佳组成，但很少提供有关野外适应和植物存活的相关信息，从而降低了方案的可重复性。我们批判性地分析了每个阶段的最佳方案，即芽形成、芽增殖、根诱导和硬化，并强调了未来研究提高繁殖效率的机会。这将有助于balcoa的可持续繁殖和利用，解决全球需求和生态挑战。

The Eastern Himalayas is a highly sensitive region experiencing an average warming trend of 0.01 ºC/yr and has exhibited and is predicted to experience an erratic precipitation pattern. The region is prone to hydrometeorological and seismic disasters. The rugged mountainous topography combined with poor geological structure has made the region very prone to climate change-induced mass wasting phenomena. Thus, the region is experiencing varied climatic extreme events that have degraded the landscapes considerably. Poorly managed land-use systems have resulted in the further deterioration of the soil characteristics and the hydrological regime. This calls for immediate attention and action through sustainable measures such as soil and water bioengineering (SWBE). We explored Nature-based Solutions (NbS) to address the above-mentioned problems through soil and water bioengineering with bamboo. The work encompassed practical solutions and provides recommendations for conserving the fragile landscapes with native bamboo species tailored to the specific problem and site. Important bamboo species for landscape stabilization include Bambusa bambos, B. balcooa, B. vulgaris, Dendrocalamus hamiltonii, D. strictus and Melocanna baccifera. Use of bamboo in crib walls, matting, and inclusion in agriculture land-use to prevent land degradation are crucial bioengineering measures. The main challenges of bioengineering, namely cost-effectiveness, durability and suitability of the species, can be overcome by carefully selecting bamboo species within the range of native species and their natural distribution in the specific problem area. To ensure that the sustainability and risk reduction from the bamboo-based SWBE efforts are moving in the direction specified by UN SDG 13 Climate Action – strengthening the resilience and adaptive capacity of infrastructure and the public to climate-related soil and water disasters – actors need to focus on specific remedial measures through proper planning, installation of SWBE structures with suitable bamboo species, management and maintenance.

东喜马拉雅是一个高度敏感的地区，平均变暖趋势为0.01 ºC/年，并已表现出并预计将经历不稳定的降水模式。该地区容易发生水文气象和地震灾害。崎岖的山地地形加上不良的地质构造使该地区极易发生气候变化引起的大规模浪费现象。因此，该地区正在经历各种极端气候事件，这些事件使景观大大退化。管理不善的土地使用系统导致土壤特征和水文制度进一步恶化。这需要立即关注并通过诸如水土生物工程（SWBE）等可持续措施采取行动。我们探索了基于自然的解决方案（NbS），通过竹子的土壤和水生物工程来解决上述问题。这项工作包含了实际的解决方案，并为保护脆弱的景观提供了根据具体问题和地点量身定制的本地竹子物种的建议。具有景观稳定作用的重要竹种有竹、竹、竹、竹、竹、竹、竹、竹等。在婴儿床墙壁上使用竹子、垫地和纳入农业土地利用以防止土地退化是至关重要的生物工程措施。生物工程的主要挑战，即成本效益、耐久性和物种的适宜性，可以通过在本地物种范围内仔细选择竹子物种及其在特定问题地区的自然分布来克服。为确保以竹子为基础的SWBE工作的可持续性和风险降低朝着联合国可持续发展目标13气候行动所规定的方向发展——加强基础设施和公众对气候相关水土灾害的复原力和适应能力——行为体需要通过适当的规划、安装具有合适竹子品种的SWBE结构、管理和维护，重点关注具体的补救措施。

The rapid expansion of Moso bamboo shoots is essential for effectively establishing Moso bamboo forests. ZIP (Zinc-regulated, Iron-regulated transporter-like Protein) refers to a group of transport proteins that are vital for the uptake and movement of zinc (Zn²⁺) and iron (Fe²⁺) as plants grow and develop. The exploration of the ZIP gene family's identification, expression patterns and possible biological roles in Moso bamboo has been limited. In our research, we discovered 17 ZIP genes present in the genome of Moso bamboo. The phylogenetic analysis indicated that these ZIPs can be divided into four distinct clades. We performed an in-depth examination of conserved motifs, gene structures, chromosomal locations, cis-regulatory elements, synteny and the characteristics and functions of gene expression within this family. Analysis of STEM time expressions derived from transcriptomic data indicated that ZIP could play a role in the swift growth and development of Moso bamboo shoots. In addition, an analysis of three-dimensional protein modeling uncovered the structural features of Moso bamboo ZIP, identifying it as a transmembrane protein that facilitates zinc ion transport. Additionally, we predicted protein interactions, analyzed transcription factors regulating ZIP, and constructed a core regulatory network associated with ZIP. Subcellular localization studies in transgenic tobacco indicated that ZIP is localized to the cell membrane. This research lays a strong groundwork for a deeper understanding of the ZIP gene family's classification and functions in Moso bamboo.

毛梭竹笋的快速扩张是有效建立毛梭竹林的必要条件。ZIP （zinc -regulated, iron -regulated transporter-like Protein）是指在植物生长发育过程中对锌（Zn2+）和铁（Fe2+）的吸收和运动至关重要的一组转运蛋白。ZIP基因家族在毛竹中的鉴定、表达模式及其可能的生物学作用的探索一直有限。在我们的研究中，我们在毛竹的基因组中发现了17个ZIP基因。系统发育分析表明，这些zip可分为4个不同的支系。我们对这个家族的保守基序、基因结构、染色体位置、顺式调控元件、合成以及基因表达的特征和功能进行了深入的研究。转录组学数据的STEM时间表达分析表明，ZIP可能在毛梭竹笋的快速生长发育中发挥作用。此外，三维蛋白质模型分析揭示了毛竹ZIP的结构特征，确定了它是一种促进锌离子运输的跨膜蛋白。此外，我们预测了蛋白相互作用，分析了调控ZIP的转录因子，并构建了与ZIP相关的核心调控网络。转基因烟草的亚细胞定位研究表明，ZIP定位在细胞膜上。本研究为深入了解毛竹ZIP基因家族的分类和功能奠定了坚实的基础。

Green materials, such as lumber, have played a vital role in the construction industry. However, global demand for lumber exceeds supply, which is driving interest in alternative materials such as engineered bamboo products. The performance of engineered bamboo is highly dependent on the strength of the adhesive used. As the industry shifts toward environmentally friendly adhesives, polyvinyl acetate (PVAc) has emerged as a candidate for bamboo adhesives. However, PVAc is known to a have lower strength than formaldehyde-based adhesives. To address this, we explored the enhancement of PVAc adhesion by pretreating the bamboo surface with a custom-built atmospheric pressure plasma jet. A significant increase in shear strength of up to 55 % was realized when the bamboo surface was treated with plasma. We attributed this to an increase in the surface free energy of bamboo, particularly the polar component. The treatment enhanced the affinity for PVAc, enabling stronger adhesion strength. The fast and relatively inexpensive atmospheric pressure plasma treatment technique offers a promising solution to improve the performance of engineered bamboo and to advance the development of more sustainable construction materials.

绿色材料，如木材，在建筑行业发挥了至关重要的作用。然而，全球对木材的需求超过了供应，这推动了人们对工程竹制品等替代材料的兴趣。工程竹的性能高度依赖于所用粘合剂的强度。随着工业向环保型胶粘剂的转变，聚醋酸乙烯酯（PVAc）已成为竹胶粘剂的候选材料。然而，已知PVAc的强度低于甲醛基胶粘剂。为了解决这个问题，我们探索了用定制的大气压等离子体射流预处理竹子表面来增强PVAc的粘附性。竹材表面经等离子体处理后，其抗剪强度显著提高了55% %。我们将其归因于竹子表面自由能的增加，特别是极性成分。该处理增强了对PVAc的亲和力，使粘接强度增强。快速且相对廉价的常压等离子体处理技术为改善工程竹子的性能和促进更可持续建筑材料的发展提供了一个有前途的解决方案。

This research investigated the effect of strengthening in bamboo-reinforced concrete (CB) columns with pilecap systems by incorporated rebar to improve seismic performance as well as prevent cracking and early failure. The parameters observed were lateral load capacity, drift ratio, relative energy dissipation and collapse patterns. The test specimens consisted of 6 bamboo-reinforced concrete columns with a reinforcement area ratio (ρ_b) of 6 %. Among these specimens, three columns were strengthened with 6 mm steel (B6) and another with 8 mm steel (B8). The control specimens were bamboo-reinforced concrete columns without strengthening (CB) and steel-reinforced concrete columns (CS), with a reinforcement area ratio of 6 % and 1.4 %, respectively. Each column was tested and subjected to cyclic lateral loads according to ACI 375.1–19 and ASTM 2126–19 with a constant axial load of 54.85 kN. B6 and B8 had greater lateral load capacity, stiffness, ductility and drift ratio than CB and CS. B6 and B8 achieved an energy dissipation ratio greater than CB and almost the same as column CS. These results suggest that the connection points of bamboo-reinforced concrete column-foundation or beam-column connections should be reinforced to improve seismic performance. The application of bamboo-reinforced concrete portal structures in simple rural houses will require strengthening at the connection points to ensure livable and technically safe houses.

本文研究了竹材混凝土（CB）柱在桩承系统中加入钢筋的加固效果，以提高其抗震性能，防止开裂和早期破坏。观察到的参数包括横向承载能力、漂移比、相对能量耗散和倒塌模式。试件为6根竹筋混凝土柱，配筋面积比（ρb）为6 %。其中3根柱采用6 mm钢（B6）加固，1根柱采用8 mm钢（B8）加固。对照试件为未加固竹筋混凝土柱（CB）和钢筋混凝土柱（CS），加固面积比分别为6 %和1.4 %。按照ACI 375.1-19和ASTM 2126-19的要求，对每根柱进行循环横向载荷测试，恒定轴向载荷为54.85 kN。B6和B8的横向承载能力、刚度、延性和漂移比均高于CB和CS。B6和B8的能量耗散比大于CB，与CS柱基本相同。这些结果表明，竹筋混凝土柱-基础连接点或梁柱连接点应进行加固，以提高抗震性能。竹筋混凝土门式结构在简单农村房屋中的应用需要在连接点进行加固，以确保房屋的宜居性和技术安全性。

Each column was tested and subjected to cyclic lateral loads according to ACI 375.1–19 and ASTM 2126–19 with a constant axial load of 54.85 kN. B6 and B8 had greater lateral load capacity, stiffness, ductility and drift ratio than CB and CS. B6 and B8 achieved an energy dissipation ratio greater than CB and almost the same as column CS. These results suggest that the connection points of bamboo-reinforced concrete column-foundation or beam-column connections should be reinforced to improve seismic performance. The application of bamboo-reinforced concrete portal structures in simple rural houses will require strengthening at the connection points to ensure livable and technically safe houses.</div></div>","PeriodicalId":100040,"journal":{"name":"Advances in Bamboo Science","volume":"13 ","pages":"Article 100198"},"PeriodicalIF":3.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145010829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molecularly imprinted polymers were employed for the purification and enrichment of flavonol glycosides and other flavonoid compounds to address the challenges of low content and structural similarity of polyphenolic flavonoids in plants, which render their separation very difficult. A magnetic molecularly imprinted polymer (MMIP) was synthesized via surface imprinting technology on Fe₃O₄@SiO₂ using vitexin as the template. Computational simulations identified methyl methacrylate (MMA) as the optimal functional monomer, with a template-to-monomer binding ratio of 1:6 and methanol as the most suitable porogen. Characterizations by TEM, XRD, VSM and FT-IR confirmed the successful synthesis of the MMIP under optimized conditions, which exhibited high adsorption capacity, rapid mass transfer and good regenerability. Binding experiments demonstrated that the MMIP had a maximum adsorption capacity of 16.1 mg/g. When directly applied to bamboo Leaves, the MMIP enabled the isolation of high-purity flavonoids, with HPLC successfully detecting six flavonoid compounds.

针对植物中多酚类黄酮含量低、结构相似等问题，采用分子印迹聚合物对黄酮醇苷类及其他类黄酮化合物进行纯化富集。以vitexin为模板剂，在Fe₃O₄@SiO₂上采用表面印迹技术合成了磁性分子印迹聚合物（MMIP）。计算模拟结果表明，甲基丙烯酸甲酯（MMA）是最佳的功能单体，模板与单体的结合比为1:6，甲醇是最合适的多孔剂。通过TEM、XRD、VSM和FT-IR表征，证实了在优化条件下成功合成的mip具有吸附量大、传质速度快、可再生性好等特点。结合实验表明，mip的最大吸附量为16.1 mg/g。当直接应用于竹叶时，MMIP可以分离出高纯度的黄酮类化合物，高效液相色谱法成功检测到6种黄酮类化合物。

The rising prevalence of micronutrient deficiencies globally necessitates innovative approaches for food fortification, particularly through the utilization of natural sources. We investigated the potential of bamboo shoot powder as a nutritional fortifier in enhancing the mineral content of common food items, specifically biscuits, salted snacks (namkeen) and noodles. The significance of food-to-food fortification is highlighted, which leverages locally available, nutrient-rich ingredients to improve dietary quality while aligning with cultural practices. The findings reveal that the incorporation of freeze-dried bamboo shoot powder significantly (P ≤ 0.05) enhances the mineral profiles of the fortified products, with notable increase in potassium content from 163.7 mg/100 g in control biscuits to 412 mg/100 g in fortified biscuits, representing a 152 % increase. Similarly, the fortified salted snacks exhibited a potassium level increase from 256.7 mg/100 g to 577.3 mg/100 g, a 125 % enhancement. In noodles, the potassium content increased significantly (P ≤ 0.05) from 160.7 mg/100 g to 603.3 mg/100 g, indicating a remarkable 275.5 % increase. Additionally, the calcium content in fortified noodle increased from 29.3 mg/100 g to 42.7 mg/100 g, while iron levels in the fortified noodles increased from 2 mg/100 g to 3.3 mg/100 g, marking a significant (P ≤ 0.05) 63.5 % enhancement. Our study underscores the importance of employing innovative processing techniques, such as freeze-drying, to preserve the nutritional integrity of bamboo shoots, making them a viable option for fortification strategies aimed at combating malnutrition. Overall, this research contributes to the ongoing discourse on food fortification and public health nutrition, highlighting the potential of bamboo shoot powder to enhance dietary quality and address critical nutritional gaps in modern diets.

全球微量营养素缺乏症日益普遍，需要采用创新的食品强化方法，特别是通过利用自然来源。我们研究了竹笋粉作为营养强化剂在提高普通食品（特别是饼干、咸味小吃和面条）中矿物质含量方面的潜力。强调了食物对食物强化的重要性，它利用当地可获得的营养丰富的成分来提高饮食质量，同时符合文化习俗。结果表明，冻干竹笋粉的加入显著（P ≤ 0.05）提高了强化饼干的矿物质含量，其中钾含量从对照饼干的163.7 mg/100 g显著增加到强化饼干的412 mg/100 g，增加了152 %。同样，强化咸味零食的钾含量从256.7 mg/100 g增加到577.3 mg/100 g，增加了125 %。面条中钾含量从160.7 mg/100 g显著提高到603.3 mg/100 g，显著提高了275.5 % （P ≤ 0.05）。此外,强化面条中的钙含量从29.3增加 42.7毫克/ 100 g  毫克/ 100 g,而铁水平强化面条从100  毫克/克增加到3.3 毫克/ 100 g,标志明显(P ≤ 0.05)63.5 %增强。我们的研究强调了采用冷冻干燥等创新加工技术来保持竹笋营养完整性的重要性，使其成为旨在对抗营养不良的强化策略的可行选择。总的来说，这项研究为食品强化和公共卫生营养的持续讨论做出了贡献，突出了竹笋粉在提高膳食质量和解决现代饮食中关键的营养缺口方面的潜力。

We investigated whether industrial transfer, an essential tool for optimizing factor allocation, contributed to the enhancement of total factor productivity (TFP) in China’s bamboo industry. To explore this relationship, we constructed a theoretical framework and employed a two-way fixed effects model. Industrial transfer was analyzed from two dimensions: changes in relative output value and changes in relative resource allocation. We found that: (1) The TFP of China’s bamboo industry was primarily driven by technological progress, with scale efficiency and technical efficiency playing a lesser role. (2) Industrial transfer, measured by relative output value change and relative resource change, significantly improved the TFP of the bamboo industry. This conclusion remained robust after accounting for endogeneity and conducting robustness tests. (3) The influence mechanism analysis revealed that in the transfer-in regions, industrial transfer boosted the TFP of the bamboo industry by optimizing the local industrial structure. However, in the transfer-out regions, it reduced land-use efficiency, hindering the development of the TFP in the bamboo industry. (4) The heterogeneity analysis revealed significant regional disparities in the effects of bamboo industry transfer on TFP. Specifically, the positive impact was more pronounced in central and western regions.

本文研究了产业转移作为优化要素配置的重要工具，是否有助于提高中国竹业的全要素生产率。为了探究这一关系，我们构建了理论框架，并采用了双向固定效应模型。从相对产值变化和相对资源配置变化两个维度分析产业转移。研究发现：(1)中国竹业全要素生产率主要受技术进步驱动，规模效率和技术效率的作用较小；(2)以相对产值变化和相对资源变化衡量的产业转移显著提高了竹产业的全要素生产率。在考虑内生性并进行稳健性检验后，这一结论仍然是稳健的。(3)影响机制分析表明，在转移区域，产业转移通过优化当地产业结构，促进了竹业全要素生产率的提高。但在外转地区，土地利用效率降低，阻碍了竹业全要素生产率的发展。(4)异质性分析表明，竹业转移对全要素生产率的影响存在显著的区域差异。具体而言，中西部地区的积极影响更为明显。

Nisha S.A. , Santhoshkumar R.

In the present study the effects of various parameters, including age of the culm, different heights of the culm and positions across the culm wall on the fibre characteristics of Ochlandra wightii were examined. The variation in fibre length, fibre width, lumen diameter and fibre wall thickness were recorded. Biometric properties such as the Runkel ratio, slenderness ratio, flexibility ratio and shape factor were analysed. Younger bamboo culms (below 1 year to 1–3 years) are better suited for pulp and paper production because of their desirable fibre qualities. The fibres of mature bamboo (more than 3 years) were less pliable, thicker and stiffer, reducing their suitability for use in papermaking.

本研究考察了不同的参数，包括茎龄、不同的秆高和跨秆壁的位置等，对白绒草纤维特性的影响。记录纤维长度、纤维宽度、管腔直径和纤维壁厚的变化。分析了龙克尔比、长细比、柔韧性比和形状因子等生物特征。较年轻的竹竿（1年以下至1 - 3年）更适合纸浆和纸张生产，因为它们具有理想的纤维品质。成熟竹子（3年以上）的纤维柔韧性较差，更厚、更硬，降低了它们在造纸中的适用性。
