    作为在家禽业中使用抗生素作为生长促进剂的替代策略的一部分,可能会出现植物性产品的饮食补充。大蒜粉(GP)具有抗菌和抗氧化性能。目的是研究饲粮补充GP对生长性能的影响。日本鹌鹑的car体性状和肉质。共有240只日龄混合性别的日本鹌鹑被分配到4个治疗组,每组复制4次,每次复制包含15只鸟。为鸟类提供基础饮食(对照)或补充0.5%的基础饮食,1%和2%GP为5周。在屠宰年龄,与对照组相比,饲喂1%GP的鸟类具有更高的(P<0.05)活重和体重增加。添加不同水平的GP对采食量无影响(P>0.05),除第三周外的饲料转化率,car体特征和腹部脂肪。硫代巴比妥酸,储存后(0、1、3、5和7d)接受GP(1%或2%)的鸟类胸肉中的过氧化物和pH值均低于对照组(P<0.05)。此外,补充任何剂量GP的禽肉中的嗜冷细菌总数均低于对照禽类.感官特征,如颜色,香气,在添加GP的组中观察到多汁性和压痛显着更好(P<0.05),尤其是在饲喂1%GP时。总之,补充1%至2%GP的饮食显示出促进生长的效果,并积极影响肉质,包括感官特征。
    Dietary supplementation with plant-based products may arise as part of an alternative strategy to using antibiotics as growth promoters in the poultry industry. Garlic powder (GP) possesses antimicrobial and antioxidant properties. The aim was to investigate the effect of dietary supplementation of GP on growth performance, carcass traits and meat quality of the Japanese quail. A total of 240, day-old mixed gender Japanese quail were assigned to 4 treatment groups, each group being replicated 4 times and containing 15 birds in each replication. Birds were provided with either a basal diet (control) or basal diet supplemented with 0.5%, 1% and 2% GP for 5 wk. At slaughter age, birds fed 1% GP had higher (P < 0.05) live weight and body weight gain when compared to the control. Supplementation with different levels of GP had no influence (P > 0.05) on feed intake, feed conversion ratio except 3rd wk, carcass traits and abdominal fat. Thiobarbituric acid, peroxide and pH values in breast meat of birds receiving GP (1% or 2%) after storage (0, 1, 3, 5, and 7 d) were lower (P < 0.05) than the birds in control. Furthermore, total psychrophilic bacteria count was lower in breast meat of birds supplemented with GP at any dose compared to the birds of control. Sensory characteristics such as color, aroma, juiciness and tenderness were observed significantly better (P < 0.05) in GP supplemented groups especially when fed 1% GP. In conclusion, supplementing the diet with 1% to 2% GP demonstrated growth-promoting effects and positively impacted meat quality, including sensory characteristics.

    本研究确定了不同链长的大蒜寡糖/多糖对葡聚糖硫酸钠(DSS)诱导的小鼠结肠炎的保护作用,并阐明了结构-功能关系。结果表明,口服大蒜寡糖/多糖降低了疾病活动指数,减少结肠缩短和脾脏肿大,并改善小鼠结肠的病理损伤。结肠前/抗炎细胞因子的失调明显减轻,伴随着上调的抗氧化酶,TLR4-MyD88-NF-κB信号通路被阻断,增强肠屏障的完整性,并恢复了SCFA的生产。大蒜低聚/多糖还通过扩大有益细菌并抑制有害细菌的生长来逆转结肠炎小鼠的肠道微生物群失调。与低分子量寡糖/多糖相比,高分子量多糖对DSS诱导的小鼠绞痛症状具有更强的缓解作用,可能是由于它们在结肠中发酵的能力更强。一起来看,这项研究证明了大蒜寡糖/多糖的抗炎作用,并表明高分子量多糖部分在缓解DSS诱导的结肠炎方面更有效.
    The present study identified the protective effects of garlic oligo/poly-saccharides of different chain lengths against dextran sulfate sodium (DSS)-induced colitis in mice and elucidated the structure-function relationships. The results showed that oral intake of garlic oligo/poly-saccharides decreased disease activity index, reduced colon shortening and spleen enlargement, and ameliorated pathological damage in the mouse colon. The dysregulation of colonic pro/anti-inflammatory cytokines was significantly alleviated, accompanied by up-regulated antioxidant enzymes, blocked TLR4-MyD88-NF-κB signaling pathway, enhanced intestinal barrier integrity, and restored SCFA production. Garlic oligo/poly-saccharides also reversed gut microbiota dysbiosis in colitic mice by expanding beneficial bacteria and suppressing the growth of harmful bacteria. High-molecular-weight polysaccharides exhibited stronger alleviating effects on DSS-induced colitic symptoms in mice than low-molecular-weight oligo/poly-saccharides did, probably due to their greater ability to be fermented in the colon. Taken together, this study demonstrated the anti-inflammatory effects of garlic oligo/poly-saccharides and revealed that high-molecular-weight polysaccharide fractions were more effective in alleviating DSS-induced colitis.

    植物多糖的抗炎作用是众所周知的。然而,免疫抑制条件下多糖的刺激作用及其与多糖结构的联系未得到充分研究。在这项工作中,通过体外和体内方法研究了大蒜多糖(GP)的免疫调节作用。据观察,GP增强了巨噬细胞(RAW264.7)的免疫反应,如一氧化氮水平升高所示。TNF-α和IL-6。然后使用免疫抑制小鼠模型探索GP能够在体外刺激免疫应答的观察。令人惊讶的是,GP对环磷酰胺(CTX)表现出剂量依赖性的上调影响,抑制细胞因子如IFN-γ和IL-6和免疫球蛋白(例如IgA和IgG)的水平。GP干预逆转了小肠和脾脏的组织病理学损伤,并增加了粪便短链脂肪酸水平。此外,GP通过增加免疫原性细菌的丰度来调节肠道微生物群的生态失调,例如g__norank_f__Erysipelotrichaceae,同时抑制g_拟杆菌的过量。功能预测表明,GP的肠道生物标志物具有糖苷水解酶家族32(GH32)和β-呋喃果糖苷酶的功能。结论是GP是免疫受损个体的有前途的免疫刺激剂。
    The anti-inflammatory effects of plant polysaccharides are well known. However, the stimulatory effects of polysaccharides under immunosuppressive conditions and their link with the polysaccharide structure is underexplored. In this work, the immune modulatory effects of a garlic polysaccharide (GP) are investigated via in vitro and vivo methods. It is observed that GP enhance the immune response of macrophages (RAW264.7) as indicated by the elevated levels of nitric oxide, TNF-α and IL-6. The observation that GP are able to stimulate the immune response in vitro was then explored with the use of an immunosuppressed mouse model. Surprisingly, GP exhibited dose-dependent up-regulatory impacts on the cyclophosphamide (CTX) suppressed levels of cytokines such as IFN-γ and IL-6 and immunoglobulins (e.g. IgA and IgG). The GP intervention reversed histopathological damage to the small intestine and spleen and increased fecal short-chain fatty acid levels. Moreover, GP modulates the gut microbiota dysbiosis by increasing the abundance of immunogenic bacteria such as g__norank_f__Erysipelotrichaceae, while inhibiting the over-abundance of g_Bacteroides. Functional predictions indicated that gut biomarkers of GP possessed the functions of glycoside hydrolase family 32 (GH32) and β-fructofuranosidase. It is concluded that GP is a promising immunostimulant for immune-compromised individuals.

    高胆固醇血症在心血管疾病的发生、发展中起着举足轻重的作用。它的预防似乎是改善这些状况的关键医疗保健策略。患有轻度高胆固醇血症的受试者由于潜在的副作用经常被建议不要使用降胆固醇药物。相反,强调将饮食调整和生活方式改变作为主要策略。在这种情况下,建议使用基于药用植物的膳食补充剂作为控制胆固醇水平升高的补充方法.这项研究的目的是研究含有大蒜和洋葱提取物的标准化制剂在解决胆固醇水平略有升高的个体的健康问题方面的安全性和潜在治疗效果。一个受控的,随机化,双盲,两组平行研究进行了8周,在基线时安排临床就诊,第2周和第4周以及研究结束时。结果显示,接受提取物的参与者的低密度脂蛋白胆固醇和总胆固醇水平显着降低。此外,改善血压,以及在氧化和炎症标志物中观察到,因此提示其作为治疗轻度高胆固醇血症的有价值的治疗干预措施的潜力.
    Hypercholesterolemia plays a pivotal role in the development and progression of cardiovascular diseases, and its prevention seems to be a crucial healthcare strategy to ameliorate these conditions. Subjects with mild hypercholesterolemia are frequently advised against using cholesterol-lowering drugs due to potential side effects, with an emphasis instead on prioritizing dietary adjustments and lifestyle modifications as the primary strategy. In this context, the use of dietary supplements based on medicinal plants may be recommended as a complementary approach to managing elevated cholesterol levels. The aim of this study was to investigate the safety and potential therapeutic effectiveness of a standardized formulation containing extracts from garlic and onions in addressing the health concerns of individuals with slightly elevated cholesterol levels. A controlled, randomized, double-blind, two parallel-group study was conducted over 8 weeks, with clinical visits scheduled at baseline, weeks 2 and 4, as well as at the end of the study. The results revealed significant reductions in both low-density lipoprotein cholesterol and total cholesterol levels among participants who received the extract. Additionally, improvements in blood pressure, as well as in oxidative and inflammatory markers were observed, thus suggesting its potential as a valuable therapeutic intervention for managing mild hypercholesterolemia.

    bZIP基因(bZIP)在许多生物过程中是必不可少的,包括发展和应激反应。尽管在许多植物中对BZIP进行了广泛的研究,尚未对大蒜中的bZIP进行全面的全基因组分析。
    在这项研究中,我们鉴定并将64个AsbZIP基因(AsbZIPs)分为10个亚家族。系统分析了这些AsbZIP的进化特征,包括染色体位置,基因结构,保守的图案,和基因复制,进行了。此外,我们还检查了核苷酸多样性,顺式作用元素,和AsbZIPs在各种组织中以及在不同非生物胁迫和激素处理下的表达谱。
    我们的发现表明,基因复制在AsbZIP的扩增中起着至关重要的作用,在驯化过程中观察到轻微的遗传瓶颈。此外,顺式作用元素的鉴定表明AsbZIP与大蒜发育的潜在关联,激素,和应激反应。几个AsbZIP表现出组织偏好和应激/激素响应表达模式。此外,Asa7G01972和Asa7G01379在各种胁迫和激素处理下显著差异表达。随后的酵母两次杂交和酵母诱导实验验证了它们与ABI5的同源物Asa1G01577的相互作用,增强了它们在激素和非生物应激反应中的重要性。本研究揭示了AsbZIP超家族的特征,为进一步分析大蒜中AsbZIP的功能奠定了坚实的基础。
    UNASSIGNED: The bZIP genes (bZIPs) are essential in numerous biological processes, including development and stress responses. Despite extensive research on bZIPs in many plants, a comprehensive genome-wide analysis of bZIPs in garlic has yet to be undertaken.
    UNASSIGNED: In this study, we identified and classified 64 AsbZIP genes (AsbZIPs) into 10 subfamilies. A systematic analysis of the evolutionary characteristics of these AsbZIPs, including chromosome location, gene structure, conserved motifs, and gene duplication, was conducted. Furthermore, we also examined the nucleotide diversity, cis-acting elements, and expression profiles of AsbZIPs in various tissues and under different abiotic stresses and hormone treatments.
    UNASSIGNED: Our findings revealed that gene replication plays a crucial role in the expansion of AsbZIPs, with a minor genetic bottleneck observed during domestication. Moreover, the identification of cis-acting elements suggested potential associations of AsbZIPs with garlic development, hormone, and stress responses. Several AsbZIPs exhibited tissue-preferential and stress/hormone-responsive expression patterns. Additionally, Asa7G01972 and Asa7G01379 were notably differentially expressed under various stresses and hormone treatments. Subsequent yeast two-hybridization and yeast induction experiments validated their interactions with Asa1G01577, a homologue of ABI5, reinforcing their importance in hormone and abiotic stress responses. This study unveiled the characteristics of the AsbZIP superfamily and lays a solid foundation for further functional analysis of AsbZIP in garlic.

    陈年大蒜,通过在高温和受控湿度下加热生大蒜(大蒜)一段时间获得,具有广泛的生物活性,但其在溃疡性结肠炎中的作用及其机制尚未完全阐明。我们研究了陈年大蒜(AG)中的生物活性成分,并探讨了口服AG对DSS诱导的小鼠结肠炎的影响。结果表明,衰老过程中抗氧化功能上调,抗炎和抗微生物化合物,如二氢咖啡酸,5-乙酰水杨酸,Verticine,S-烯丙基-L-半胱氨酸和D-岩藻糖。口服AG明显缓解结肠炎,减少结肠损伤,增强抗氧化和抗炎作用。大肠杆菌和马链球菌在与帕金森病密切相关的结肠炎小鼠的结肠中显著富集,细菌入侵上皮细胞,氧气素生物合成,和血红素生物合成,但是由于Akkermansia粘液的丰度增加,结肠中的AG介导的明显改变,乳酸杆菌。L-YJ,短双歧杆菌,Blautiawexlerae,脱硫微生物。P100A,并观察到了丘陵乳杆菌。接下来,我们证明口服AG重建结肠微生物组显着增加短链脂肪酸如乙酸的产生,丙酸,异丁酸,和异戊酸。这项研究提供了第一个数据,表明口服AG以肠道微生物群依赖的方式改善结肠炎症。我们的发现为AG介导的结肠炎缓解和AG作为调节肠道微生物群预防和治疗结肠炎的功能性食物提供了新的见解。
    Aged garlic, obtained by heating raw garlic (Allium sativum) under high temperature and controlled humidity for a period, possesses a wide range of bioactivities, but its role in ulcerative colitis and its mechanism are not fully elucidated. We investigated the bioactive constituents in aged garlic (AG) and explored the effect of oral AG delivery on DSS-induced murine colitis. The results revealed that the aging process up-regulated anti-oxidative, anti-inflammatory and anti-microbial compounds such as dihydrocaffeic acid, 5-acetylsalicylic acid, verticine, S-allyl-L-cysteine and D-fucose. Oral AG obviously alleviated colitis, reducing colon damage and enhancing anti-oxidative and anti-inflammatory effects. Escherichia coli and Streptococcus equinus dramatically were enriched in the colon of mice with colitis that were strongly associated with Parkinson\'s disease, bacterial invasion of epithelial cells, aerobactin biosynthesis, and heme biosynthesis, but a distinct AG-mediated alteration in the colon due to increasing abundance of Akkermansia muciniphila, Lactobacillus sp. L-YJ, Bifidobacterium breve, Blautia wexlerae, Desulfomicrobium sp. P100A, and Lentilactobacillus hilgardii was observed. Next, we demonstrated that colonic microbiome reconstruction by oral AG significantly increased the production of short-chain fatty acids such as acetic acid, propionic acid, isobutyric acid, and isovaleric acid. This study provides the first data indicating that oral AG ameliorates colonic inflammation in a gut microbiota-dependent manner. Our findings provide novel insights into the AG-mediated remission of colitis and AG as a functional food for modulating the gut microbiota to prevent and treat colitis.

    Climate change is an imminent threat, particularly affecting agricultural productivity, which relies heavily on weather conditions. Understanding the specific impacts of climate change on key crops is crucial for developing effective adaptation strategies to ensure food security. The growth patterns of onions and garlic were observed at over ten different locations in South Korea, and the yield data from the past 40 years were analyzed. The yield was significantly correlated with temperature and strongly affected by the frequent and unexpected patterns of precipitation. The increase in mean temperature during winter and the spatial and temporal concentration of precipitation are expected to be the most influential factors for Allium crop production in the future. In addition, the yields of onions and garlic can serve as good indicators for predicting the impacts of weather on agricultural productivity, given their extended cultivation periods and significant correlations with temperature and precipitation. As climate change scenarios become available, the results of this study can serve as a basis for predicting changes in agricultural production in the future and identifying opportunities to adapt cultivation systems for food security.

    精油(EO)的包封是一种重要的策略,可用于增强这些化合物在害虫综合治理中的稳定性和效率。本研究旨在研究基于聚合物的EOs纳米颗粒对红面粉甲虫的亚致死活性,蓖麻成虫是储存产品的重要关键害虫。使用离子交联技术制备的含有大蒜和肉桂精油(GEO和CEO)的壳聚糖纳米颗粒(CSNP)。随温度和储存时间评估的纳米制剂的稳定性。确定熏蒸效果(LC10,LC20,LC30)和接触毒性(LC10,LC15,LC25)。此外,EO及其纳米颗粒对营养指标的接触毒性评价。用于评估亚致死熏蒸剂浓度下CSNP(EO@CSNP)中EO和EO的驱除活性的嗅觉计。表征结果表明,CSNP中加载的GEO的粒径为231.14±7.55nm,多分散指数(PDI)值为0.15±0.02,封装效率(EE)百分比为76.77±0.20,zeta电位为-18.82±0.90mV,其中CSNP中加载的CEO的这些值(CEO@CSNP)更改为303.46±0.00nm,0.20±0.05,86.81±0.00%和-20.16±0.35mV,分别。两个CSNP的较低PDI值显示适当的NP大小分布。此外,NPs大小和包封效率在各种温度下和在四个月期间没有变化,这证实了E0@CSNP的良好稳定性。在GEO@CSNP的LC30中,最大驱避性为66.66±3.33。在营养指数中,在GEO@CSNP的LC25中,相对生长速率(RGR)(0.011±0.003mg。mg-1。day-1),相对消耗率(RCR)(0.075±0.004mg。mg-1。day-1)和摄食威慑指数(FDI)(54.662±1.616%)受影响较大,所以GEO@CSNP比CEO@CSNP更有效。EO和EO@CSNP的驱避性和抗饮食活性的结果证实,与游离EO相比,用EO@CSNP处理的蓖麻害虫的营养指数具有更高的驱避性和不利影响。总之,GEO和CEO的NPs形式可以成为一种新颖有效的载体,用于改善EO的驱除和抗营养活性。
    Encapsulation of essential oils (EOs) is an important strategy that can be applied to intensify the stability and efficiency of these compounds in integrated pest management. The present study aimed to investigate the sub-lethal activity of polymer-based EOs nanoparticles against red flour beetle, Tribolium castaneum adults as an important critical pest of stored products. Chitosan nanoparticles (CSNPs) containing garlic and cinnamon essential oils (GEO and CEO) prepared using the ionic cross-link technique. Stability of nano-formulations evaluated over temperature and storage time. The fumigant effect (LC10, LC20, LC30) and contact toxicity (LC10, LC15, LC25) determined. In addition, the contact toxicities of EOs and their nanoparticles on nutritional indices evaluated. An olfactometer used to assess the repellent activity of EOs and EOs loaded in CSNPs (EOs@CSNPs) in sub-lethal fumigant concentrations. Characterization results showed GEO loaded in CSNPs has particle size of 231.14 ± 7.55 nm, polydispersity index (PDI) value of 0.15 ± 0.02, encapsulation efficiency (EE) percentage of 76.77 ± 0.20 and zeta potential of - 18.82 ± 0.90 mV, in which these values for the CEO loaded in CSNPs (CEO@CSNPs) changed to 303.46 ± 0.00 nm, 0.20 ± 0.05, 86.81 ± 0.00% and - 20.16 ± 0.35 mV, respectively. A lower PDI value for both CSNPs showed an appropriate NPs size distribution. Furthermore, NPs size and encapsulation efficiency did not change in various temperatures and during four months which confirm good stability of the EOs@CSNPs. In LC30 of GEO@CSNPs, the maximum repellency was determined as 66.66 ± 3.33. Among nutritional indices, in LC25 of GEO@CSNPs, the relative growth rate (RGR) (0.011 ± 0.003 mg.mg-1.day-1), relative consumption rate (RCR) (0.075 ± 0.004 mg.mg-1.day-1) and feeding deterrence index (FDI) (54.662 ± 1.616%) were more affected, so GEO@CSNPs was more effective than CEO@CSNPs. The results of repellent and anti-dietary activities of EOs and EOs@CSNPs confirmed the higher repellency and adverse effectivity on nutritional indices of Tribolium castaneum pest treated with EOs@CSNPs compared to free EOs. In conclusion, the NPs form of GEO and CEO can be a novel and efficient carrier for improving the repellent and anti-nutritional activities of EOs.
