    当氧化应激发生时,自由基和活性氧会开始。(1)研究背景:天然分子对高脂血症大鼠氧化应激的影响,服用他汀类药物,被观察到。(2)方法:一百一十二只白色Wistar大鼠,男性和女性,分为七个:第一组接受20mg阿托伐他汀,而第二组和第三组接受20mg阿托伐他汀和100mg沙棘和葡萄提取物的组合。第IV组和第V组接受100毫克沙棘和葡萄提取物,而VI组和VII组仅接受高脂饮食(HFD)和正常啮齿动物饲料。两个月和六个月后,对大鼠实施安乐死,收集血液以测量主要临床值和总抗氧化能力(TAC)。此外,肝脏和肾脏被储存用于器官的细胞结构。对于统计数据,双向方差分析(ANOVA),已执行。(3)结果:HFD产生高脂血症,伴随着增强的血清和肝脏氧化应激标志物,除了抗氧化酶活性和谷胱甘肽水平的降低。多酚物质被证明对HFD引起的氧化应激有效。(4)结论:阿托伐他汀加重了脂肪饮食引起的组织学损伤,但是通过服用阿托伐他汀与100mg/kg植物提取物的组合,这些减少了。
    Free radicals and reactive oxygen species initiate when the oxidative stress arises. (1) Background: The effect of natural molecules on oxidative stress in hyperlipidemic rats, taking statins, was observed. (2) Methods: One hundred and twelve white Wistar rats, males and females, were divided into seven: Group I received 20 mg of atorvastatin while groups II and III received a combination of 20 mg of atorvastatin and 100 mg of Sea buckthorn and grape extract. Groups IV and V received 100 mg of Sea buckthorn and grape extract, while groups VI and VII received only high-fat diet (HFD) and normal rodents\' fodder. After two and six months, rats were euthanized, and blood was gathered to measure the main paraclinical values and total antioxidant capacity (TAC). Also, the liver and kidney were stored for the organs\' cytoarchitecture. For statistics, two-way analysis of variance (ANOVA), was performed. (3) Results: HFD produced hyperlipidemia, accompanied by augmented serum and hepatic oxidative stress markers, in addition to a reduction in antioxidant enzyme activities and glutathione levels. Polyphenolic substances proven efficient against HFD caused oxidative stress. (4) Conclusions: Atorvastatin heightened the histological injuries caused by the fatty diet, but these were diminished by taking atorvastatin in combination with 100 mg/kg of plant extracts.

    据报道,紫外线B(UV-B)辐射会引起氧化应激和炎症介导的皮肤光损伤。此外,线粒体动力学在这些过程中起关键作用。第一次,我们在这项研究中描述了UVB诱导的异常线粒体动力学和炎症如何在原代人真皮成纤维细胞(HDFs)中相互作用。我们的发现表明,UV-B辐射通过增加HDFs中的线粒体片段来诱导线粒体动力学损伤。不平衡的线粒体动力学导致NFκB和促炎细胞因子的激活。目前的研究进一步旨在研究柚皮素(一种从沙棘果肉中分离的天然类黄酮)对HDFs和Balb/c小鼠中UV-B诱导的线粒体片段化和炎症的保护作用。虽然柚皮素已被证明具有抗炎和抗氧化的潜力,其对UVB诱导的炎症的影响和作用机制尚不清楚。我们观察到柚皮素恢复了UV-B诱导的HDFs线粒体裂变和融合的失衡。它还抑制NFκB的磷酸化并减少促炎细胞因子的产生。柚皮素还通过清除活性氧和上调细胞抗氧化酶(过氧化氢酶和Nrf2)来减轻UV-B诱导的氧化应激。将柚皮素局部应用于暴露于UV-B辐射的Balb/c小鼠的背部皮肤可防止线粒体碎裂和炎症反应的进展。柚皮素治疗可预防小鼠皮肤中性粒细胞浸润和表皮增厚。这些发现为进一步研究受损的线粒体动力学作为UV-B诱导的炎症的治疗靶标提供了理解。我们的发现暗示柚皮素可以开发为针对UVB引起的炎症的治疗药物。
    Ultraviolet-B (UV-B) irradiation has been reported to cause oxidative stress and inflammation-mediated skin photo-damage. Furthermore, mitochondrial dynamics have been implicated to play a critical role in these processes. For the first time, we describe in this study how UVB-induced aberrant mitochondrial dynamics and inflammation interact in primary human dermal fibroblasts (HDFs). Our findings demonstrated that UV-B irradiation induced -impairment in mitochondrial dynamics by increasing mitochondrial fragmentation in HDFs. Imbalanced mitochondrial dynamics lead to the activation of NFкB and pro-inflammatory cytokines. The current study further aimed to investigate the protective effect of Naringenin (a naturally occurring flavonoid isolated from Sea buckthorn fruit pulp) against UV-B-induced mitochondrial fragmentation and inflammation in HDFs and Balb/c mice. Although Naringenin has been shown to have anti-inflammatory and antioxidant potential, its effects and mechanisms of action on UVB-induced inflammation remained unclear. We observed that Naringenin restored the UV-B-induced imbalance in mitochondrial fission and fusion in HDFs. It also inhibited the phosphorylation of NFкB and reduced the generation of pro-inflammatory cytokines. Naringenin also alleviated UV-B-induced oxidative stress by scavenging the reactive oxygen species and up-regulating the cellular antioxidant enzymes (Catalase and Nrf2). Topical application of Naringenin to the dorsal skin of Balb/c mice exposed to UV-B radiation prevented mitochondrial fragmentation and progression of inflammatory responses. Naringenin treatment prevented neutrophil infiltration and epidermal thickening in mice\'s skin. These findings provide an understanding for further research into impaired mitochondrial dynamics as a therapeutic target for UV-B-induced inflammation. Our findings imply that Naringenin could be developed as a therapeutic remedy against UVB-induced inflammation.

    Cardiovascular diseases are a broadly understood concept focusing on vascular and heart dysfunction. Lack of physical exercise, type 2 diabetes, obesity, hypertension, dyslipidemia, thromboembolism, and kidney and lung diseases all contribute to the development of heart and blood vessel dysfunction. Although effective and important, traditional treatment with diuretics, statins, beta blockers, calcium inhibitors, ACE inhibitors, and anti-platelet drugs remains a second-line treatment after dietary interventions and lifestyle changes. Scientists worldwide are still looking for an herbal product that would be effective and free from side effects, either taken together with or before the standard pharmacological intervention. Such herbal-originated medication therapy may include Morus alba L. (white mulberry), Elaeagnus rhamnoides (L.) A. Nelson (sea-buckthorn), Allium sativum L. (garlic), Convallaria majalis L. (lily of the valley), Leonurus cardiaca L. (motherwort), and Crataegus spp. (hawthorn). Valuable herbal raw materials include leaves, fruits, seeds, and even thorns. This short review focuses on six herbs that can constitute an interesting and potential therapeutic option in the management of cardiovascular disorders.

    溃疡性结肠炎(UC)的特点是慢性炎症和肠内膜溃疡,导致各种症状。沙棘浆果含有一种生物活性化合物,称为沙棘多糖(SBP)。然而,SBP对UC影响的确切机制尚不清楚.在这项研究中,我们研究了SBP预处理对DSS诱导的结肠炎的影响。我们的研究结果表明,SBP预处理有效地减少炎症,氧化应激,以及与结肠炎相关的肠屏障损伤。为了进一步阐明SBP调节的肠道菌群在UC中的作用,我们对DSS处理的小鼠进行了粪便微生物群移植(FMT)。来自SBP处理的小鼠的微生物群表现出显著的抗炎和抗氧化作用,改善结肠屏障的完整性,并增加有益细菌的丰度,以及提高SCFA的生产。总的来说,这些结果强烈表明,SBP介导的结肠炎改善归因于其对肠道微生物群的影响,特别是通过促进产生SCFA的细菌和随后提高SCFA水平。这项研究提供了令人信服的证据,支持先发制人SBP补充剂通过调节肠道微生物群缓解结肠炎症状的功效,从而提供了对SBP作为肠道微生物群调节因子缓解结肠炎的潜力的新见解。
    Ulcerative colitis (UC) is characterized by chronic inflammation and ulceration of the intestinal inner lining, resulting in various symptoms. Sea buckthorn berries contain a bioactive compound known as sea buckthorn polysaccharide (SBP). However, the precise mechanisms underlying the impact of SBP on UC remain unclear. In this study, we investigated the effects of pretreatment with SBP on colitis induced by DSS. Our findings demonstrate that SBP pretreatment effectively reduces inflammation, oxidative stress, and intestinal barrier damage associated with colitis. To further elucidate the role of SBP-modulated gut microbiota in UC, we performed fecal microbiota transplantation (FMT) on DSS-treated mice. The microbiota from SBP-treated mice exhibits notable anti-inflammatory and antioxidant effects, improves colonic barrier integrity, and increases the abundance of beneficial bacteria, as well as enhancing SCFA production. Collectively, these results strongly indicate that SBP-mediated amelioration of colitis is attributed to its impact on the gut microbiota, particularly through the promotion of SCFA-producing bacteria and subsequent elevation of SCFA levels. This study provides compelling evidence supporting the efficacy of pre-emptive SBP supplementation in alleviating colitis symptoms by modulating the gut microbiota, thereby offering novel insights into the potential of SBP as a regulator of the gut microbiota for colitis relief.

    Dioecy的进化维持是一种复杂的现象,因物种和潜在途径而异。此外,不同性别可能在植物和生殖功能之间表现出可变的资源分配(RA)模式。这种差异反映在性二态性的程度上。虽然很少追求,对具有中间性表型的植物物种的调查可能会揭示有关性别比例和进化途径的策略的有用信息。我们研究了H.rhamnoidesssp。Turkestanica,一种雌雄异株的物种,具有多甲异株(PGM)植物,在喜马拉雅西部。该物种自然栖息在从三角洲到山坡的各种栖息地中。该物种的这些属性有利于测试非生物因素对性二态性的影响,和不同性别之间的RA策略。该研究证明了植物和生殖特征的性二态性。性二态性指数,排列像身高这样的特征,分支数量,花卉生产,和干重的花与雄性,而其他包括鲜重的叶子,荆棘的数量,果实产量与雌性显著相关。RA模式的差异在雄性和雌性植物的繁殖性状中更为明显,而在PGM植物中,性状重叠。总的来说,栖息地条件不影响性二态或RA模式的程度。然而,这似乎会影响次要性别比例,因为雌性显示出与土壤湿度的显着关联。我们关于性二态性和RA模式的发现支持该物种的风授粉属性。在物种中观察到的性二态性程度重申了性别之间有限的基因组差异以及物种中通过单一性的持续进化。随着物种在资源有限和极端环境中生长,物种中RA的动态似乎与栖息地的资源可用性无关。
    Evolutionary maintenance of dioecy is a complex phenomenon and varies by species and underlying pathways. Also, different sexes may exhibit variable resource allocation (RA) patterns among the vegetative and reproductive functions. Such differences are reflected in the extent of sexual dimorphism. Though rarely pursued, investigation on plant species harbouring intermediate sexual phenotypes may reveal useful information on the strategy pertaining to sex-ratios and evolutionary pathways. We studied H. rhamnoides ssp. turkestanica, a subdioecious species with polygamomonoecious (PGM) plants, in western Himalaya. The species naturally inhabits a wide range of habitats ranging from river deltas to hill slopes. These attributes of the species are conducive to test the influence of abiotic factors on sexual dimorphism, and RA strategy among different sexes. The study demonstrates sexual dimorphism in vegetative and reproductive traits. The sexual dimorphism index, aligned the traits like height, number of branches, flower production, and dry-weight of flowers with males while others including fresh-weight of leaves, number of thorns, fruit production were significantly associated with females. The difference in RA pattern is more pronounced in reproductive traits of the male and female plants, while in the PGM plants the traits overlap. In general, habitat conditions did not influence either the extent of sexual dimorphism or RA pattern. However, it seems to influence secondary sex-ratio as females show their significant association with soil moisture. Our findings on sexual dimorphism and RA pattern supports attributes of wind-pollination in the species. The observed extent of sexual dimorphism in the species reiterates limited genomic differences among the sexes and the ongoing evolution of dioecy via monoecy in the species. The dynamics of RA in the species appears to be independent of resource availability in the habitats as the species grows in a resource-limited and extreme environment.

    背景:作为青藏高原(QTP)的特有灌木,西藏沙棘的分布。海拔2800至5200米。作为沙棘属最基础的分支,西藏有广泛的进化史。藏鱼是研究极端条件下物种生态进化的宝贵树木。
    结果:这里,我们产生了一个高质量的西藏嗜血杆菌染色体水平的基因组。组装基因组的总大小为917Mb。对1064个单拷贝基因的系统基因组分析显示,藏鱼的Mya在3.4和12.8之间存在差异。与DNA修复和抗病性相关的多个基因家族在西藏汉堡包中显著扩增。我们还鉴定了许多与DNA修复相关的基因,这些基因具有正选择的迹象。这些结果表明,在QTP中,扩展和积极选择可能在藏语花序对全面极端环境的适应中起重要作用。一项全面的基因组和转录组学分析确定了49个参与藏花菜类黄酮生物合成途径的基因。我们产生了转基因沙棘毛状根,产生了高水平的类黄酮。
    结论:综合来看,该高质量的藏鱼基因组揭示了植物在极端环境下的适应机制,为藏鱼的功能基因组研究和分子育种奠定了基础。
    BACKGROUND: As an endemic shrub of the Qinghai-Tibetan Plateau (QTP), the distribution of Hippophae tibetana Schlecht. ranges between 2800 and 5200 m above sea level. As the most basal branch of the Hippophae genus, H. tibetana has an extensive evolutionary history. The H. tibetana is a valuable tree for studying the ecological evolution of species under extreme conditions.
    RESULTS: Here, we generated a high-quality chromosome-level genome of H. tibetana. The total size of the assembly genome is 917 Mb. The phylogenomic analysis of 1064 single-copy genes showed a divergence between 3.4 and 12.8 Mya for H. tibetana. Multiple gene families associated with DNA repair and disease resistance were significantly expanded in H. tibetana. We also identified many genes related to DNA repair with signs of positive selection. These results showed expansion and positive selection likely play important roles in H. tibetana\'s adaptation to comprehensive extreme environments in the QTP. A comprehensive genomic and transcriptomic analysis identified 49 genes involved in the flavonoid biosynthesis pathway in H. tibetana. We generated transgenic sea buckthorn hairy root producing high levels of flavonoid.
    CONCLUSIONS: Taken together, this H. tibetana high-quality genome provides insights into the plant adaptation mechanisms of plant under extreme environments and lay foundation for the functional genomic research and molecular breeding of H. tibetana.
