PURPOSE Canine cone-rod dystrophy 1 (cord1) has been previously mapped to CFA15, and a homozygous 44-bp insertion in exon 2 (Ins44) of canine RPGRIP1 (cRPGRIP1(Ins/Ins)) has been associated with the disease. However, from the recent identification of a significant discordance in genotype-phenotype association, we have reexamined the role of cRPGRIP1 in cord1. METHODS Retinal structure and fun...
We recently showed that mutations in the CNGA3 gene encoding the alpha-subunit of the cone photoreceptor cGMP-gated channel cause autosomal recessive complete achromatopsia linked to chromosome 2q11. We now report the results of a first comprehensive screening for CNGA3 mutations in a cohort of 258 additional independent families with hereditary cone photoreceptor disorders. CNGA3 mutations wer...
در این رساله، طراحی، اجراء و مدلسازی فرآیند nano-edm مورد بررسی و تحقیق قرار گرفت. به منظور تولید نانو- ابزار مناسب برای فرآیند nano-edm یک دستگاه اتوماتیک طراحی و ساخته شد که با استفاده از آن، تاثیر متغیرهای فرآیند ساخت بر خصوصیات نانو- ابزار مورد تحقیق قرار گرفت. با شناسایی سطوح بهینه متغیرهای فرآیند ساخت به روش تاگوچی، نانو- ابزارهایی با شعاع نوک حدود 10 نانومتر و ضریب جانبی (نسبت طول به شعا...

Dihydrolipoamide acyltransferase (E2), a catalytic and structural component of the three functional classes of multienzyme complexes that catalyze the oxidative decarboxylation of alpha-keto acids, forms the central core to which the other components attach. We have determined the structures of the truncated 60-mer core dihydrolipoamide acetyltransferase (tE2) of the Saccharomyces cerevisiae py...
where S is the Landweber-Novikov algebra. S has the added advantage of being a cocommutative Hopf algebra over Z. This paper does not remove this difficulty, but we will show that the monoid of multiplicative operations in BP*BP, (i.e. those operations which induce ring endomorphisms on BP*X for any space X)9 which we will denote by Γ{BP), has a submonoid analogous to the monoid of multiplicati...
In this paper a stepwise compaction process of a ring semi-stiff polymer chain placed in a 3d conical nano-cavity and being under the action of the increasing external field is studied. Compaction from a circlelike shape to several toroidal-like loops for a three-dimensional system was observed. The thermodynamic stability of these toroidal-like structures was investigated by observing a hyster...
Abstract In this study, we investigated the mechanical properties and chloride ion permeation resistance of geopolymer mortars based on fly ash modified with nano-SiO 2 (NS) polyvinyl alcohol (PVA) fiber metakaolin (MK) at dose levels 0–1.2% for PVA 0–2.5% NS. The Levenberg–Marquardt (L–M) back propagation (BP) neural network, as well radial-based function (RBF) was used to predict compressive ...
Retinal bipolar (BP) cells mediate the earliest steps in image processing in the visual system, but the genetic pathways that regulate their development and function are incompletely known. We identified PRDI-BF1 and RIZ homology domain containing 8 (PRDM8) as a highly conserved transcription factor that is abundantly expressed in mouse retina. During development and in maturity, PRDM8 is expre...
