Some new criteria for the oscillation of advanced functional differential equations of the form d dt ([ 1 an−1(t) d dt 1 an−2(t) d dt · · · 1 a1(t) d dt x(t) ]α) + δ q(t)f(x[g(t)]) = 0 are presented in this paper. A discussion of neutral equations will also be included.

We investigate the existence ofmultiple positive solutions for three-point boundary value problemof fractional differential equation with p-Laplacian operator −Dt β (φp(Dt α x))(t) = h(t)f(t, x(t)), t ∈ (0, 1), x(0) = 0,Dt γ x(1) = aDt γ x(ξ),Dt α x(0) = 0, where Dt β ,Dt α ,Dt γ are the standard Riemann-Liouville derivatives with 1 < α ≤ 2, 0 < β ≤ 1, 0 < γ ≤ 1, 0 ≤ α − γ − 1, ξ ∈ (0, 1) and t...

Dual-tasking (DT) is a measure to detect impairments in people with multiple sclerosis (MS). We compared three DT methods to determine whether cognitive (Montreal Cognitive Assessment (MoCA)) or physical disability (Expanded Disease Severity Scale; EDSS) was related to DT performance. We recruited MS participants with low disability (<3 EDSS, n = 13) and high disability (≥3 EDSS, n = 9) and mat...

We examined regional mechanics of the left ventricular free wall in naturally pumping dog hearts during beta-blockade. Local systolic wall force (F) and segment length (L) were obtained with an auxotonic force gauge and an ultrasonic dimension gauge, both inserted at the equatorial level of the wall to measure F and L in the circumferential direction. Shortening velocity (-dL/dt) was obtained b...

INTRODUCTION Desmoid tumors (DT) are rare benign tumors that do not metastasize, but tend to invade locally. DT are frequently seen in patients with familial adenomatous polyposis (FAP), and diagnosis and treatment are often difficult. METHOD The article presents the clinical picture, diagnosis and treatment of DT in patients registered in the Danish Polyposis Register by the end of 1999. R...

Students referred to treatment after violating campus drug policies represent a high-risk group. Identification of factors related to these students' cannabis use could inform prevention and treatment efforts. Distress tolerance (DT) is negatively related to substance-related behaviors and may be related to high-risk cannabis use vulnerability factors that can impact treatment outcome. Thus, th...

New equations for paralyzable, non paralyzable and hybrid DT models, valid for any time dependent sources are presented. We show how such new equations include the equations already used for constant rate sources, and how it's is possible to correct DT losses in the case of time dependent sources. Montecarlo simulations were performed to compare the equations behavior with the three DT models. ...

1H-1H and 31P-1H nuclear Overhauser effects and 31P NMR spin-lattice relaxation times were measured for a synthetic DNA poly(dA-dT).poly(dA-dT) in a low-salt aqueous solution. The results have shown that all bases in the double helix are anti-orientated with respect to deoxyribose residues and that the sugar-phosphate backbone has an alternating architecture.

Some new criteria for the oscillation of the fourth order functional differential equation d dt ( 1 a3(t) ( d dt 1 a2(t) ( d dt 1 a1(t) ( d dt x(t) )α1)α2)α3) + δq(t) f (x[g(t)]) = 0, where δ = ±1 are established. c © 2006 Elsevier Ltd. All rights reserved.

Tumor cells in hypoxic areas of solid tumors are resistant to conventional chemotherapy and radiotherapy and thus are obstacles of cancer therapy. We report here the feasibility of applying hypoxia-regulated expression of diphtheria toxin A (DT-A) for killing hypoxic tumor cells. The expression vector was constructed to express DT-A fused with hypoxia-inducible factor-1A (HIF-1A) oxygen-depende...
