Alzheimer's disease, one of the neurodegenerative diseases, shows the progressive senescence of neural progenitor/stem cells. N-Stearoyl-L-tyrosine (NsTyr) showed neuroprotective effect against chronic brain ischemia in previous reports. In the present study, we find the antisenescent effects of NsTyr-2K in NSPCs induced by Aβ 1-42 in vitro. Cell viability of NSPCs was evaluated by CCK8 assay; ...

The immunogenicity of single, private H-2 specificities has been tested. In most cases, the specificity was known to be confined either to H-2K or to H-2D. This was accomplished by the appropriate choice, as donor and recipient, or parent of the F(1) hybrid recipient, of congenic strains differing at H-2 only, and of recombinant haplotypes in donor and/or recipient. By nearly all tests, the H-2...

We construct two families of orthogonal product quantum states that cannot be exactly distinguished by local operation and classical communication (LOCC) in the quantum system of (2k+i) ⊗ (2l+j) (i, j ∈ {0, 1} and i ≥ j ) and (3k+i) ⊗ (3l+j) (i, j ∈ {0, 1, 2}). And we also give the tiling structure of these two families of quantum product states where the quantum states are unextendible in the ...

This study compared the contractile responses elicited by angiotensin II (AII), arginine vasopressin (AVP), and 5-hydroxytryptamine (5-HT) in isolated occipital arteries (OAs) from sham-operated (SHAM) and 2-kidney, 1-clip (2K-1C) hypertensive rats. OAs were isolated and bisected into proximal segments (closer to the common carotid artery) and distal segments (closer to the nodose ganglion) and...

The problem was first proposed by Blum [1] and Blum and Langley [2]. Ever since, the first nontrivial algorithm was given by [4], which runs in time n0.7kpoly(log 1/δ, 2k, n), for general juntas and n 2 3 poly(log 1/δ, 2k, n) for symmetric juntas. We give an algorithm for symmetric juntas which runs in time nk/3(1+o(1))poly(log 1/δ, 2k, n). We further show that when k is bigger than some large ...

Recently Lin Xin gave an explicit formula for the integer part of reciprocals ∑k=n∞k−2. In this paper we extend result on k2 to (ak)2, where a is positive integer. We give formulas alternating sum and squares odd integers. Further, reciprocal sums (2k)4 (2k−1)4.

We survey combinatorial interpretations of some dozen identities for the double factorial such as, for instance, (2n− 2)!! + ∑n k=2 (2n−1)!!(2k−4)!! (2k−1)!! = (2n − 1)!!.

We show that a necessary and sufficient condition for the existence of a P2k-factorization of the complete bipartitemultigraph )"Km,n is m = n == 0 (mod k(2k l)/d), where d = gcd()", 2k 1).

The spontaneously hypertensive rat (SHR) exhibits angiotensin II (Ang II)-dependent oxidative stress and reduced efficiency of renal oxygen usage (QO2) for tubular sodium transport (TNa). We tested the hypothesis that oxidative stress determines the reduced TNa:QO2 ratio in the clipped kidney of the early 2-kidney, 1-clip (2K,1C) Ang II-dependent model. One week after sham operation (Sham) or c...

Previously, we demonstrated that adult blood pressure was increased in offspring of rabbit mothers with chronic secondary renal hypertension. Our study identified sex-specific differences in the programming of hypertension, with female, not male, offspring, having increased blood pressure at 30 wk of age. The aim of this study was to characterize the maternal hypertension during pregnancy to de...
