BACKGROUND We have recently reported that the susceptibility vessel sign (SVS) at the proximal portion of the horizontal (M1) middle cerebral artery (MCA) on T2*-weighted MRI is a strong predictor for no early recanalization after intravenous recombinant tissue plasminogen activator (t-PA) therapy. However, it is unclear whether the presence of the SVS at other locations, such as distal M1, the...
We re ne a conjecture of M. O. Locks and J. M. Wilson [Reliability Engineering and System Safety 46 (1994), 283-286] regarding disjoint forms of the Abraham Reliability problem. We also present other examples of reliability problems with the interesting property that their minimal disjoint forms do not arise from the familiar tautologyM1+:::+Mn M1+(M2 M1)+(M3 M2 M1)+:::+(Mn Mn 1 ::: M1):
DB289 [2,5-bis(4-amidinophenyl)furan-bis-O-methylamidoxime] is biotransformed to the potent antiparasitic diamidine DB75 [2,5-bis(4-amidinophenyl) furan] by sequential oxidative O-demethylation and reductive N-dehydroxylation reactions. Previous work demonstrated that the N-dehydroxylation reactions are catalyzed by cytochrome b5/NADH-cytochrome b5 reductase. Enzymes responsible for catalyzing ...
OBJECTIVE Human macrophages can shift phenotype across the inflammatory M1 and reparative M2 spectrum in response to environmental challenges, but the mechanisms promoting inflammatory and cardiometabolic disease-associated M1 phenotypes remain incompletely understood. Alternative splicing (AS) is emerging as an important regulator of cellular function, yet its role in macrophage activation is ...
A peptide containing the CCHH motif, the putative zinc-binding sequence of influenza virus M1 protein, was found to bind zinc in a one-to-one complex with the characteristics of a typical zinc-binding peptide. Intact influenza virus also contained zinc and we show that this zinc is bound to the M1 protein in the virus. However, only a small proportion of M1 contained zinc: 4% in virus and 6 to ...
Acetylcholine serves an important modulatory role in the central nervous system. Pharmacological evidence has suggested that cholinergic activity can modulate central dopaminergic transmission; however, the nature of this interaction and the receptors involved remain undefined. In this study we have generated mice lacking the M1 muscarinic acetylcholine receptor and examined the effects of M1 d...
با استفاده از کشت برونتنی 24 ساعته میکروارگانیسمهای شکمبه، در این مطالعه تأثیر ظرفیت بافری 2 ترکیبات معدنی (m1=119.43 و m2=116.5 میلیاکیوالان در لیتر) را بر ارزش اسیدزایی شکمبهای (av)، ph، ناپدید شدن ماده خشک (ivdmd) و خروج متان در شرایط برونتنی جیرههای گاوهای شیری شیرده حاوی نسبتهای مختلف علوفه به کنسانتره 60:40 و 70:30 را در یک طرح کاملاً تصادفی بررسی شد. ترکیبات معدنی در جیرههای آزما...
