Rif Valley Fever Surveillance: Fao Animal Production and Health Manual No. 21
為了解決Livestock agent 的問題，作者 這樣論述：
This manual provides risk-based guidance for designing, planning and implementing effective participatory and syndromic surveillance of Rift Valley fever (RVF). It shows how to tailor this guidance to the epidemiological needs of individual countries, starting with setting appropriate objectives. RV
F virus, a mosquito-borne zoonotic agent, causes haemorrhagic fever in humans, and abortion and neonatal death in livestock. Outbreaks have caused national meat markets to collapse and have provoked regional trade embargoes. The geography of infection and clinical disease is expanding, also because
of climate change. This publication argues that effective surveillance is essential to mitigate the impact of RVF. For this reason, RVF surveillance objectives need to be in line with the country's risk category and economic goals. The manual suggests questions to help build a timely and sensitive s
urveillance system suited to national objectives and resources Founded in 1945, the Food and Agriculture Organization (FAO) leads international efforts to defeat hunger. Serving both developed and developing countries, FAO provides a neutral forum where all nations meet as equals to negotiate agre
ements and debate policy. The Organization publishes authoritative publications on agriculture, fisheries, forestry and nutrition.
萊克多巴胺對斑馬魚幼魚心血管、呼吸和運動生理的評價
為了解決Livestock agent 的問題，作者趙柏宇 這樣論述：
萊克多巴胺 (Ractopamine, RAC) 是一種 β-腎上腺素受體激動劑，用於促進牲畜的瘦肉和提高食物轉化效率。這種化合物被認為會導致家畜（如豬）的行為和生理發生改變。很少有研究探討 RAC 在水生動物中的潛在非目標效應。在本研究中，我們通過評估運動活力、耗氧量和心血管功能等多個參數，探索斑馬魚急性暴露RAC後的生理反應。斑馬魚幼魚在 0.1、1、2、4 或 8 ppm 的RAC 暴露 24 小時，並監測和量化相對應的心血管、呼吸和運動活力。此外，我們還對 RAC 與 10 種斑馬魚內源性 β-腎上腺素受體進行了分子對接，以闡明 RAC 的作用機制。結果表明，RAC 可以顯著提高運動
活力、心臟性能、耗氧量和血流量，但不會影響斑馬魚胚胎的心律規律。基於結構的分子對接，RAC 對所有 10 種內源性 β-腎上腺素受體亞型（從 adra1aa 到 adra2db）都表現出相似的結合親和力，與人類相同。這一結果表明 RAC 可作為高效、廣譜的 β-腎上腺素受體激動劑，促進斑馬魚的運動活力、心臟功能和耗氧量。為了驗證我們的結果，我們使用β-受體阻滯劑(Propranolol, PROP)與 RAC 共同培養。 PROP 暴露可以減少斑馬魚幼魚的運動過度活躍、高耗氧量和高心率。基於計算機結構的分子模擬和結合親和力測試表明，PROP 的結合親和力總體上低於 RAC。總之，我們的研究提供
了可靠的活體證據，支持 RAC可以調節斑馬魚的心血管、呼吸和運動生理。

為了解決Livestock agent 的問題，作者Mezrich, Ben 這樣論述：
A real-life mix of The X-Files and Close Encounters of the Third Kind, Mezrich "writes vividly and grippingly...A terrific story... that] will make a heck of a movie" (TheWashington Post). Here is the "fascinating" (Publishers Weekly) true story of a computer programmer who tracks paranormal events
in remote areas of the western United States and is drawn deeper and deeper into a mysterious conspiracy.Like Agent Mulder of The X-Files, microchip engineer and sheriff's deputy Chuck Zukowski is obsessed with tracking down UFO reports in Colorado. He even takes the family with him on weekend trip
s to look for evidence of aliens. But this innocent hobby takes on a sinister urgency when Zukowski learns of mutilated livestock--whose exsanguination is inexplicable by any known human or animal means. Along an expanse of land stretching across the southern borders of Utah, Colorado, and Kansas, Z
ukowski documents hundreds of bizarre incidences of mutilations, and discovers that they stretch through the heart of America. His pursuit of the truth draws him deeper into a vast conspiracy, and he journeys from Roswell and Area 51 to the Pentagon and beyond; from underground secret military caver
ns to Native American sacred sites; and to wilderness areas where strange, unexplained lights traverse the sky at extraordinary speeds. Inspiring and terrifying, Mezrich's "dramatic narrative...connects dots we didn't even know existed...Something's clearly happening out there in the high meadows an
d along desert highways" (Kirkus Reviews). The 37th Parallel will make you, too, wonder if we are really alone.
巴拉圭家飼動物外侵襲病媒蜱之蜱媒介病原體的分子檢測
為了解決Livestock agent 的問題，作者Cristell Janette Duarte Cheretti 這樣論述：
研究背景: 雖然已有許多研究報導有關南美洲國家之蜱媒介疾病，然而卻僅有極少數研究有關巴拉圭之蜱種分佈及病原體傳播。因而本研究將有貢獻於巴拉圭及南美洲之科學、醫學及獸醫界。研究目的: 我們的目的將運用蜱種形態特徵，以確認採集自巴拉圭四個省份之家飼動物外侵襲蜱種株，同時並使用巢式聚合酶鏈反應及定序分析技術，以檢測蜱隻感染立克次體菌狀況及確認其基因種。研究方法: 所有採集自家飼動物之蜱隻於2011年5至8月期間完成，並使用蜱隻移除鑷子自動物摘離後置於標示密封袋內於冰箱內保存，直至運抵實驗室後置入含75%酒精之離心管內，並使用立體解剖顯微鏡以鑑定其蜱屬及種株。每隻蜱隻於萃取核酸(DNA)前皆經超音波
震盪清洗，並針對邊蟲之16S rRNA基因進行巢式聚合酶鏈反應之檢測，檢測得之陽性樣本再續以基因定序處理。研究結果: 所有蜱隻採集自犬、貓、牛、馬及羊等31個宿主動物，共計採得來自巴拉圭四個省份之333蜱隻，蜱種鑑定顯示其中包含54.6%之微小牛蜱(Rhipicephalus microplus)、27.6%之褐黃狗蜱(Rhipicephalus sanguineus)、 14.1%之革蜱(Dermacentor nitens) 及 3.6%之五種花蜱(Amblyomma spp.)。而針對邊蟲16S rRNA基因進行邊蟲感染之分子檢測，則顯示採得蜱隻分別具有6.6% (22/333)及21.
3% (71/333) 之A. marginale 及A.centrale的陽性率，而陽性樣本之定序結果亦顯示與GenBank資料庫已知之A. marginale and A. centrale具有100%基因序列相似度。討論: 本研究顯示扇頭蜱屬(Rhipicephalus spp.)乃巴拉圭多數區域家飼動物之主要寄生蜱種，由於採集得花蜱數量較少，故而無法於本研究確認其實際盛行狀況。本研究結果證實A. marginale 及A. centrale兩種邊蟲存在於巴拉圭蜱隻，並分別具有6.6% 及21.3%之感染率。本結果亦建議有關蜱媒介邊蟲病之漠視及誤診，此狀況促使邊蟲感染成為巴拉圭公衛上被忽
略之重要動物疾病，並威脅人類健康。
