As Ti rich Ti-Al alloy shows ductile nature with the α2 + γ lamellar structure [1], the mechanism of microstructural evolution in Ti-Al alloys has attracted much interest. Since the lamellar structure is formed by the continuous cooling in industrial processes, cooling rate dependence of α → γ and α → α2 + γ transformations has been extensively studied by many researchers [2-5]. Wang et al. [2,...

previous in vitro work on rabbit knee joint vessels showed that vasoconstrictor effects of nerve stimulation and administration of α-adrenoceptor agonists were mediated predominantly by α1-adrenoceptors5,9 the present experiments were performed to assess the nature of α-adrenoceptor subtypes within these blood vessels in vivo. dose/response relationships for adrenaline and noradrenaline produce...

The Alexandrov–Fenchel inequality bounds from below the square of mixed volume V(K1,K2,K3,…,Kn) convex bodies K1,…,Kn in ℝn by product volumes V(K1,K1,K3,…,Kn) and V(K2,K2,K3,…,Kn). As a consequence, for integers α1,…,αm∈ℕ with α1+⋯+αm=n Vn(K1)α1n⋯Vn(Km)αmn suitable powers Vn(Ki) Ki, i=1,…,m, is lower bound V(K1[α1],…,Km[αm]), where αi multiplicity which Ki appears volume. It has been conjectur...

E. coli ribonucleotide reductase catalyzes the reduction of nucleoside 5′-diphosphates into 2′deoxynucleotides and is composed of two subunits: α2 and β2. During turnover, a stable tyrosyl radical (Y·) at Y122-β2 reversibly oxidizes C439 in the active site of α2. This radical propagation step is proposed to occur over 35 Å, to use specific redox-active tyrosines (Y122 and Y356 in β2, Y731 and Y...

Let C be a binary code of length n. For a four-tuple α = (α0, α1, α2, α3) of non-negative integers summing to n, let `α = ∣∣{(c, c) ∈ C × C : wt(c) = α2 + α3, ∂(c, c ) = α1 + α3,wt(c ) = α1 + α2 }∣∣ . We study the biweight enumerator WC(y0, y1, y2, y3) = ∑ α=(α0,α1,α2,α3) `α y α0 0 y α1 1 y α2 2 y α3 3 . For binary linear codes, MacWilliams identities for this enumerator were given by MacWillia...

BACKGROUND. Diabetic retinopathy (DR) is the leading cause of blindness in the world. Retinopathy can still progress despite optimal metabolic control. The aim of the study was to determine whether different degrees of DR (proliferative or nonproliferative) were associated with abnormally modulated hemostatic parameters in patients with T1DM. METHOD. 52 T1DM patients and 40 healthy controls wer...

GM (grey matter) changes of thalamus and basal ganglia have been demonstrated to be involved in AD (Alzheimer's disease). Moreover, the increase of a specific EEG (electroencephalogram) marker, α3/α2, have been associated with AD-converters subjects with MCI (mild cognitive impairment). To study the association of prognostic EEG markers with specific GM changes of thalamus and basal ganglia in ...

OBJECTIVE The purpose of the present study was to investigate the expression of the α2-integrin subunit and heat shock protein 47 (Hsp47) in two families with isolated gingival fibromatosis (GF) form and one family with GF associated with dental abnormalities and normal gingival (NG). STUDY DESIGN Immunohistochemistry was performed with antibodies against α2-integrin and Hsp47 in specimens fr...

Migraine is a complex brain disorder, and understanding the complexity of this prevalent disease could improve quality of life for millions of people. Familial Hemiplegic Migraine type 2 (FHM2) is a subtype of migraine with aura and co-morbidities like epilepsy/seizures, cognitive impairments and psychiatric manifestations, such as obsessive-compulsive disorder (OCD). FHM2 disease-mutations loc...
