This study investigates the impact of three different instructional models, direct model (DIM), experiential learning (ELM), and their combinations (DIM-ELM) on enhancing critical thinking, metacognition, conceptual understanding in an introductory physics course. The included 84 first-year pre-engineering students aged 18-24 years who were enrolled course at two public science technology unive...
Natural killer (NK) cells are circulating cytotoxic lymphocytes that exert potent and nonredundant antiviral activity and antitumoral activity in the mouse; however, their function in host defense in humans remains unclear. Here, we investigated 6 related patients with autosomal recessive growth retardation, adrenal insufficiency, and a selective NK cell deficiency characterized by a lack of th...
We report flow cytometric characterization of surface CD26 expression in 271 peripheral blood samples from 154 patients evaluated for the presence of a T-cell lymphoproliferative disorder, primarily mycosis fungoides/Sézary syndrome (MF/SS). The presence of morphologically identifiable tumor cells on peripheral blood smears was the criterion for lymphomatous involvement. In 66 of 69 samples fro...
We prove the long-standing Eckmann{Ruelle conjecture in dimension theory of smooth dynamical systems. We show that the pointwise dimension exists almost everywhere with respect to a compactly supported Borel probability measure with non-zero Lyapunov exponents, invariant under a C 1+ diieomorphism of a smooth Riemannian manifold. Let M be a smooth Riemannian manifold without boundary, and f : M...
Human CD56(bright) natural killer (NK) cells possess little or no killer immunoglobulin-like receptors (KIRs), high interferon-gamma (IFN-gamma) production, but little cytotoxicity. CD56(dim) NK cells have high KIR expression, produce little IFN-gamma, yet display high cytotoxicity. We hypothesized that, if human NK maturation progresses from a CD56(bright) to a CD56(dim) phenotype, an intermed...
The inductive dimension dim(G) of a finite undirected graph G is a rational number defined inductively as 1 plus the arithmetic mean of the dimensions of the unit spheres dim(S(x)) at vertices x primed by the requirement that the empty graph has dimension −1. We look at the distribution of the random variable dim on the Erdös-Rényi probability space G(n, p), where each of the n(n− 1)/2 edges ap...
Detailed analysis of peripheral blood natural killer (NK) cells in women with recurrent miscarriage.
BACKGROUND Increased peripheral blood natural killer (NK) cell activity has been associated with unexplained reproductive failure including recurrent (three or more) miscarriages (RM). Studies have reported abnormalities in both numbers (absolute and proportion) and activation. This study assessed numerous NK cell parameters to determine which (if any) are altered in women with RM compared with...
The dimension of a poset (X, P), denoted dim (A", P), is the minimum number of linear extensions of P whose intersection is P. It follows from Dilworth's decomposition theorem that dim (X, P)& width (X, P). Hiraguchi showed that dim(X, P)s \X\/Z In this paper, A denotes an antichain of (A", P) and E the set of maximal elements. We then prove that dim {X, P) s |X A\; dim(X, P) < 1 + width (X E);...
DIM (3,3'-di-indolylmethane), an abundant dietary component of cruciferous vegetables, exhibits a wide spectrum of pharmacological properties. In the present study, we show that DIM is a potent inhibitor of Leishmania donovani topoisomerase I with an IC50 of 1.2 microM. Equilibrium dialysis shows that DIM binds strongly to the free enzyme with a binding constant of 9.73x10(-9) M. The binding af...
