同碳雙碳烯以非傳統的方法進行 非過渡金屬誘導化學合成

為了解決benz s class的問題，作者陳玉珍 這樣論述：

同碳雙碳烯 (carbodicarbene, CDC) 是一種電子贈與能力很強的零價碳配位基，由於中心碳上具有兩對孤對電子，因此在反應特性上與其他形式的配位基有很大的差異性。本論文的第一部分主要探討CDC中引入一個弱的布氏酸 (Brønsted acid) -苯甲醇做為共調節器，藉由兩者的結合使CDC具有極為類似受阻路易斯酸鹼對 (Frustrated Lewis Pair, FLP) 的反應性。利用DFT計算與實驗所得的結果可以證實，苯乙醇藉由氫鍵及-堆積作用與CDC結合形成弱的交互作用，這種協同效應大大的提升了CDC的催化能力，使其在異氰酸酯衍生物的環三聚合反應 (cyclotri

merization)、乳酸交酯 (L-lactide, LA) 的開環聚合反應、甲基丙烯酸甲酯 (methyl methacrylate, MMA) 的聚合反應及醇類化合物的去氫矽基化反應 (dehydrosilylation) 中得到了印證。在CDC分子中具有兩個相反的反應部位 (親核性及親電性)，此與傳統的氮異環碳烯 (N-heterocyclic carbene, NHC) 有明顯的差異性，因此在結合共調節劑或共催化劑後所產生的效應，可以提供更多樣化的FLP催化活性。本論文的第二部分探討具有自身氧化還原 (redox-noninnocence) 能力的CDC化合物，它可以提升醇類化合物

與活化(缺電子)的芳香環進行去硝基/去鹵素之 C-O鍵耦合反應的效率，並擁有優異的反應產率；由實驗的結果排除了典型的有機芳香族親核取代 (SNAr) 反應的機制，我們推測可能是藉由單電子轉移 (SET) 完成此反應。本論文的研究成果將會對未來產生下列幾種衝擊性: (1) CDC化合物作為有機催化劑的廣泛應用性；(2) 藉由添加具有可調控功能的分子來增加FLP反應性的多樣化；(3) 具有自身氧化還原能力的CDC形成陽離子自由基，能夠提升無過渡金屬催化的化學合成反應。

Formula 1: Car by Car: 1950-59

為了解決benz s class的問題，作者Higham, Peter 這樣論述：

The formative years of the 1950s are explored in this fourth installment of Evro's decade-by-decade series covering all Formula 1 cars and teams. When the World Championship was first held in 1950, red Italian cars predominated, from Alfa Romeo, Ferrari and Maserati, and continued to do so for much

of the period. But by the time the decade closed, green British cars were in their ascendancy, first Vanwall and then rear-engined Cooper playing the starring roles, and BRM and Lotus having walk-on parts. As for drivers, one stood out above the others, Argentine Juan Manuel Fangio, becoming World C

hampion five times. Much of the fascination of this era also lies in its numerous privateers and also-rans, all of which receive their due coverage in this complete work. Year-by-year treatment covers each season in fascinating depth, running through the teams -- and their various cars -- in order o

f importance. Alfa Romeo's supercharged 11/2-litre cars dominated the first two years, with titles won by Giuseppe Farina (1950) and Fangio (1951). The new marque of Ferrari steamrollered the opposition in two seasons run to Formula 2 rules (1952-53), Alberto Ascari becoming champion both times, and

the same manufacturer took two more crowns with Fangio (1956) and Mike Hawthorn (1958). Maserati's fabulous 250F, the decade's most significant racing car, propelled Fangio to two more of his five championships (1954 and 1957). German manufacturer Mercedes-Benz stepped briefly into Formula 1 (1954-

55) and won almost everything with Fangio and up-and-coming Stirling Moss. Green finally beat red when the Vanwalls, driven by Moss and Tony Brooks, won the inaugural constructors' title (1958). Then along came Cooper, rear-engine pioneers, to signpost Formula 1's future when Jack Brabham became Wor

ld Champion (1959). Peter Higham works in motor racing as a writer and project manager. For nearly 30 years he worked for Haymarket Consumer Media, publisher of motor racing magazines and websites, and for half of that period he was director of LAT Photographic (now Motorsport Images), the world’s

largest motor racing photo archive. A motor racing enthusiast since watching his first race in 1973, he has written seven books, including the acclaimed International Motor Racing Guide and World Encyclopaedia of Racing Drivers. He has been a columnist for Autosport and Motor Sport and was instrume

ntal in running the prestigious Autosport Awards for over 25 years. He lives in Twickenham, Middlesex.

Metformin一種降血糖biguanide衍生物在離體及活體實驗中對抗血小板所引起的動脈栓塞所扮演的新角色

為了解決benz s class的問題，作者許嘉元 這樣論述：

第二型糖尿病(Type 2 diabetes, T2D)是一種內分泌異常所導致的疾病，近年來已成為全球第九大死亡原因。T2D的患者常伴隨著許多併發症例如：慢性腎臟疾病 (chronic kidney diseases, CKDs)、心血管疾病 (cardiovascular diseases, CVDs)、高血壓及神經退化性疾病，其中造成T2D患者死亡的原因主要為CKDs及CVDs。Metformin目前是治療T2D的一線臨床用藥，許多研究證明了metformin可以改善CVDs及CKDs；研究顯示血小板 (platelet) 在CVDs和腦血管疾病 (cerebrovascular dis

eases) 中扮演著關鍵角色，對於止血和動脈血栓的形成亦至關重要的作用。根據研究指出metformin (1 mM) 可以透過活化protein kinase A顯著降低棕櫚酸 (palmitic acid) 刺激的人臍靜脈內皮細胞 (human umbilical vein endothelial cell, HUVEC) 功能障礙和抑制藉由ADP (adenosine diphosphate) 刺激大鼠的血小板活化及粒線體功能障礙 (mitochondrial dysfunction)，顯見metformin對於生物體內的抗血小板效果卓越；因此metformin可能是治療動脈血栓形成的潛

在藥物。然而，在過去的文獻中僅有一篇研究證實了metformin在動物體內的抗血小板作用，因此在本研究中我們將首度使用人類血小板確認metformin在血小板活化中的分子機制，並進一步評估其在動物小鼠體內的有效性。研究結果顯示，metformin (1.2 mM~1.8 mM) 抑制膠原蛋白 (collagen, 1 μg/ml) 所刺激的血小板凝集作用 (aggregation) 但對於花生四烯酸 (arachidonic acid, AA; 60 μM)、U46619 (1 μM) 和凝血酶 (thrombin, 0.05 U/ml) 刺激的血小板活化沒有顯著影響。此外，metformin

(1.2 mM和1.8 mM) 顯著抑制由collagen所刺激的 ATP (adenosine triphosphate) 和鈣離子釋放、P-selectin的表現以及降低phospholipase C (PLC)γ2、protein kinase C (PKC)、mitogen-activated protein kinase (MAPK)、PI3K (phosphoinositide 3-kinase)、Akt及glycogen synthase kinase-3β (GSK3β) 的蛋白磷酸化，但對於vasodilator-stimulated phosphoprotein (VAS

P) 蛋白磷酸化並無影響。另外，在動物研究中metformin (250 mg/kg; i.p.) 明顯降低了急性肺栓塞 (acute pulmonary thromboembolism) 的死亡率且並不會造成出血的副作用產生。綜上所述，此研究結果證實了metformin可以作為有效抑制DM相關的血小板活化之新一類抗血小板藥物。
