Objective(s): Ceftriaxone (Cef), a beta-lactam antibiotic, is accompanied by antioxidant and anti-inflammatory properties. It has been shown that Cef has beneficial effects on Alzheimer’s disease. In the current investigation, the effect of Cef in a mice model of aging was investigated. Materials and Methods: Forty male mice were equally...
در این مقاله برای گزینه نصب مولدهای تولید پراکنده در ایستگاه های سی ان جی، ظرفیت الکتریکی بهینه و پارامترهای اقتصادی متناظر، بر اساس حداکثر شدن ارزش فعلی خالص تعیین میگردند. همچنین حساسیت نسبت به پارامترهای مختلف، مورد ارزیابی قرار میگیرد. در این مطالعه علاوه بر قید حداکثر حجم سرمایه گذاری ممکن، قیود مربوط به نحوه صحیح پخش بار و سطح اتصال کوتاه مجاز در شبکه، نیز مورد ملاحظه قرار میگیرند. در مدل...
Dystroglycan (DG), a cell adhesion molecule well known to be essential for skeletal muscle integrity and formation of neuromuscular synapses, is also present at inhibitory synapses in the central nervous system. Mutations that affect DG function not only result in muscular dystrophies, but also in severe cognitive deficits and epilepsy. Here we demonstrate a role of DG during activity-dependent...
Two deoxyglucose (DG) derivatives, (α,β)-2-deoxy-2-amino(ethylcarbamate)-D-glucose (ECB-DG) and (α,β)-2-deoxy-2-amino(1,2-dihydroxypropyl)-D-glucose (DHP-DG), were synthesized and radiolabeled successfully with [(99m)Tc(H2O)3(CO)3](+) complex. [(99m)Tc]-ECB-DG and [(99m)Tc]-DHP-DG complexes were prepared (96% and 93% radiochemical purities respectively) by using 46 mCi of Na(99m)TcO4 in 1 mL sa...
Abstract. For a (molecular) graph G with vertex set V (G) and edge set E(G), the first and second Zagreb indices of G are defined as M1(G) = ∑ v∈V (G) dG(v) 2 and M2(G) = ∑ uv∈E(G) dG(u)dG(v), respectively, where dG(v) is the degree of vertex v in G. The alternative expression of M1(G) is ∑ uv∈E(G)(dG(u) + dG(v)). Recently Ashrafi, Došlić and Hamzeh introduced two related graphical invariants M...
In vertebrates, mutations in Protein O-mannosyltransferase1 (POMT1) or POMT2 are associated with muscular dystrophy due to a requirement for O-linked mannose glycans on the Dystroglycan (Dg) protein. In this study we examine larval body wall muscles of Drosophila mutant for Dg, or RNA interference knockdown for Dg and find defects in muscle attachment, altered muscle contraction, and a change i...
The concept of Koszul differential graded algebra (Koszul DG algebra) is introduced. Koszul DG algebras exist extensively, and have nice properties similar to the classic Koszul algebras. A DG version of the Koszul duality is proved. When the Koszul DG algebra A is AS-regular, the Ext-algebra E of A is Frobenius. In this case, similar to the classical BGG correspondence, there is an equivalence...
