In the article by Deng et al, “miR-143 Activation Regulates Smooth Muscle and Endothelial Cell Crosstalk in Pulmonary Arterial Hypertension,” which published in the October 23, 2015 issue of the journal (Circ Res. 2015;117:870–883. doi: 10.1161/CIRCRESAHA.115.306806), the authors have requested a correction based on errors in data presentation and analysis discovered during the PhD thesis exami...

سابقه و هدف: در سال­ های اخیر روند رو به افزایش تخریب منابع آب، خاک محیط زیست اثر کاربرد بی رویه مواد شیمیایی موجب ترغیب پژوهشگران کشاورزی ارگانیک سال ­های شده است. با وجود همه اثرات مثبتی که ارتباط مصرف آلی بر روی ویژگی­ فیزیکی مطرح است، هنوز این رابطه نگرانی­ زیادی از نظر مسائل زیست­ محیطی، سلامت دارد. بسته منبع، اغلب دارای مقادیر نسبتا عناصر سنگین می باشند؛ بنابراین اندازه گیری دقیق میزان فل...

We derive a 3f +1 process Byzantine Paxos consensus algorithm by Byzantizing a variant of the ordinary Paxos algorithm—that is, by having 2f + 1 nonfaulty processes emulate the ordinary Paxos algorithm despite the presence of f malicious processes. We have written a formal, machine-checked proof that the Byzantized algorithm implements the ordinary Paxos consensus algorithm under a suitable ref...

(III) from (I) and of 21-norpregnan-20-als (IV) from (II) (Brooks & Norymberski, 1953). The last conversion was presumed; it is now established by the isolation of 3,-hydroxy-21-norpregn-5-en-20-al (VI) (as its acetate) from the reaction of pregn-5ene-3f:20fl:21-triol (V) with sodium bismuthate. Reduction with borohydride followed by oxidation with sodium bismuthate was expected to convert 20:2...
