Beta systematic risk的問題,我們搜遍了碩博士論文和台灣出版的書籍,推薦Ghayur, Khalid/ Heaney, Ronan G./ Komon, Stephen A./ Platt, Stev寫的 ActiveBeta Indexes: Capturing Systematic Sources of Active Equity Returns 可以從中找到所需的評價。

臺北醫學大學 醫學生物科技博士學位學程 林詠峯所指導 MONIKA的 阿滋海默症檢體中醛加合物對 β-類澱粉蛋白之產生、修飾和自體免疫的改變 (2021),提出Beta systematic risk關鍵因素是什麼,來自於β-澱粉樣蛋白 (Aβ)、阿滋海默症 (AD)、4-羥基壬烯醛 (HNE) 加合物、丙烯醛加合物、代謝症候群、自體抗體、轉譯後修飾。

而第二篇論文國立宜蘭大學 生物技術與動物科學系動物科學碩士班 游玉祥所指導 莊凱博的 靈芝水萃液於肉雞發炎模式下對生長性能、腸道型態及盲腸菌相之影響 (2021),提出因為有 肉雞、靈芝、免疫調節的重點而找出了 Beta systematic risk的解答。

接下來讓我們看這些論文和書籍都說些什麼吧:

阿滋海默症檢體中醛加合物對 β-類澱粉蛋白之產生、修飾和自體免疫的改變

為了解決Beta systematic risk的問題,作者MONIKA 這樣論述:

目的:阿滋海默症 (AD)好併發於多種疾病,包括代謝異常在內。代謝症候群 (MetS) 患者經常表現出高血糖和異常血脂,這會導致醛加合物,如丙烯醛和 4-羥基壬烯醛 (HNE) ,在血液和大腦中的胜肽上形成。不過,MetS與 AD 之間的病理生理學關聯仍不清楚。澱粉樣蛋白-β (Aβ) 是 AD 的標誌之一,其產生與由MetS引起的脂質過氧化導致丙烯醛和 HNE 加合物的形成相關。本研究的重點是想進一步了解 Aβ、醛加合物(丙烯醛和 HNE)和對應的自體抗體(IgG 和 IgM)在MetS和AD發展過程中的相互作用。方法:我們使用了在neuro-2a 細胞中表達的瑞典和印第安納澱粉樣前體蛋白

(APP-Swe/Ind) 突變的 AD 細胞模型和 3xTg-AD 小鼠模型。收集臨床數據和人血清(對照組和 AD組)樣本。根據對照組和AD組中是否有MetS,將人類樣本進一步分為四組。使用免疫熒光顯微鏡、組織化學、免疫沉澱、免疫墨點和/或 ELISA 檢查樣品以分析 APP、Aβ、丙烯醛和 HNE 加合物。丙烯醛和 HNE用於體外修飾合成的 Aβ1-16和 Aβ17-28 胜肽,並使用液相層析串聯質譜儀 (LC-MS/MS) 確認。使用天然的和醛修飾的(丙烯醛和 HNE)Aβ胜肽測定血清中特定自體抗體 IgG 和 IgM 的濃度。並分析了潛在生物標誌物之間的相關性和診斷能力。結果:與對照

組相比,AD 模型(細胞、小鼠和人類檢體)中的丙烯醛加合物濃度升高,而所有患病組的 HNE 加合物濃度增加。此外,在 3xTg-AD 小鼠血清、腦裂解物和人血清中發現 APP 羧端片段 (APP-CTF) 和 Aβ寡聚體具有丙烯醛加合物。丙烯醛和 HNE 加合物的含量與作為MetS指標的空腹三酸甘油酯和血糖呈正相關,與高密度脂蛋白膽固醇呈負相關。與對照組相比,代謝紊亂組的丙烯醛和 HNE 加合物含量顯著增加。一個有趣的發現是,AD-M 組的抗丙烯醛-Aβ自體抗體,尤其是 IgM,遠低於MetS組,這表明在從MetS到 AD 的發病過程中,針對丙烯醛加合物的特異性抗體可能會降低。相反,患病組的大

多數自體抗體含量較高,可識別天然的或 HNE 修飾的 Aβ。然而,對於高血糖和 AD,HNE 加合物在診斷能力方面優於 Aβ。此外,與高血糖組相比,高血糖 AD 組的 HNE-Aβ胜肽含量更高,對應的自體抗體(最顯著的是 IgM)更低,這表明從高血糖到 AD 的發病機制中存在免疫破壞。結論:丙烯醛和HNE的加合反應可能是代謝失衡引起的,但這種作用通常會被自體抗體中和。當這些自體抗體不足時,MetS可能導致 AD。根據數據,我們得出結論,血清中的丙烯醛加合物似乎比Aβ和 HNE等為更好追踪MetS和 AD 發病機制的生物標誌物。丙烯醛和 HNE 加合物與由此產生的自體抗體可能是 AD 免疫治療和

診斷的潛力生物標誌物,特別是當MetS是一種合併症時。

靈芝水萃液於肉雞發炎模式下對生長性能、腸道型態及盲腸菌相之影響

為了解決Beta systematic risk的問題,作者莊凱博 這樣論述:

靈芝(Ganoderma lucidum)在過去亞洲地區的傳統文化中就已經被當中藥材廣泛使用在治療或是預防疾病的發生,由於靈芝中的多醣體已被證實具有調節免疫力、抗發炎、抗氧化、抗癌和抗菌等功能,因此本試驗將探討靈芝水萃液作為肉雞抗發炎的飼料添加物之功效。本研究分為三個試驗,試驗一目的為測定靈芝的體外抗菌效果及生物活性成分的定量,試驗二是使用葡聚醣硫酸鈉(dextran sulfate sodium, DSS)作為肉雞促發炎藥物並測試靈芝水萃液對生長性能、腸道型態、抗發炎效果及腸道菌相的影響,試驗三使用脂多醣(lipopolysaccharide, LPS)誘導肉雞發炎並觀察靈芝水萃液對生長性

能、腸道型態、抗發炎效果及腸道菌相的功能。試驗結果顯示,靈芝水對金黃色葡萄球菌及大腸桿菌具有抑菌效果,此外,在兩種攻毒模式中靈芝水萃液都無法改善其生長性能,但在腸道的發炎基因(COX2、iNOS、IL-1β和IL-6) mRNA表現量皆有抑制的效果;在DSS攻毒的試驗中靈芝無法提高小腸的絨毛長度,但在LPS試驗中靈芝水萃液的高低劑量處理和對照組相比都顯著提高空腸和迴腸的絨毛長度;試驗二的腸道菌相豐富度會因為給予靈芝水萃液而顯著提高,並且抑制了變形菌門的比例,試驗三的結果則是可以發現給予高劑量靈芝水萃液處理會使alpha diversity中的simpson和shannon下降,腸道內乳酸桿菌的

數量相對上升,原本因為LPS攻毒而下降的糞桿菌也恢復成和對照組一樣的水平。綜合上述,靈芝水萃液無論是在DSS或是LPS攻毒皆具有抑制發炎反應的效果,並促進腸道內有益菌的含量,且幫助腸道菌群穩定,在LPS試驗中也能提高絨毛長度增加吸收面積,因此靈芝水萃液具有作為抗發炎飼料添加物的潛力。
