Research ArticleOpen accessIn the abstractMeasures on the Quotient Spaces of the IntegersNorris Sookoo, Peter ChamiSK-partitions were introduced by Sharma and Kaushik, who defined distances (metrics) between vectors in terms of partitions of the alphabet set Fq , the set of the ring of integers modulo q. These distances were applied in Coding Theory. The research examined algebraic and topological aspects of SK-partitions and related sets of measures. A lattice of SK-partitions was introduced and … …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 7,009 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA New Algorithm for Subset Matching ProblemYangjun ChenThe subset matching problem is to find all occurrences of a pattern string p of length m in a text string t of length n, where each pattern and text position is a set of characters drawn from some alphabet ∑. The pattern is said to occur at text position i if the set p[j] is a subset of the … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 6,737 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Combined Phytohemagglutinin And α-Ketoglutarate Pharmacology Study of Gut Morphology and Growth in Older Adult RatsR. Filip, A. Harrison, S. G. PierzynowskiThis study has evaluated the effect of phytohaemagglutinin (PHA) in combination with alpha-ketoglutaric acid (AKG), on GI-tract morphology and N balance in adult rats. Rats, aged approx. 15 months, were assigned to one of four experimental groups, (1) Control group, (2) AKG group, (3) AKG+PHA 100% group and (4) AKG+PHA 1% group. AKG and AKG+PHA were administered via a stomach … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,082 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProbabilistic Artificial Neural Network For Recognizing the Arabic Hand Written CharactersKhalaf khatatneh, Ibrahiem M.M. El Emary, Basem Al-RifaiThe objective of this study was to present a new technique assists in developing a recognition system for handling the Arabic Hand Written text. The proposed system is called Arabic Hand Written Optical Character Recognition (AHOCR). AHOCR was concerned with recognition of hand written Alphanumeric Arabic characters. In the present work, extracted characters are represented by using geometric moment invariant … …Journal of Computer Science, Vol. 2, Issue 12 · 31 Dec 2006 · 6,911 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCortisol Response Mediates HIV-1-Related Cognitive Deficits Among Injecting Drug AbusersRaymond L. Ownby, Drenna Waldrop-Valverde, Adarsh M. Kumar et al.The cortisol response is an important measure of the endocrine activity to environmental challenges and has been related to cognitive function and mood. Previous studies have shown that the cortisol response to stress is dysregulated in persons with HIV-1 infection. Since cortisol is neurotoxic and its levels have been related to cognitive dysfunction in various disorders, it is possible that … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 6,759 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHeroin-Induces Differential Protein Expression by Normal Human Astrocytes (NHA)Jessica L. Reynolds, Supriya D. Mahajan, Donald Sykes, Madhavan P.N. NairHeroin use is postulated to act as a cofactor in the neuropathogenesis of human immunodeficiency virus (HIV-1) infection. Astrocytes, integral components of the CNS, are reported to be susceptible to HIV-1 infection. Upon activation, astrocytes release a number of immunoregulatory products or modulate the expression of a number of proteins that foster the immunopathogenesis of HIV-1 infection. However, the role … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 7,261 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssociation Between Circulating Early Endothelial Progenitors and CD4+CD25+ Regulatory T Cells: A Possible Cross-talk between Immunity and Angiogenesis?Shmuel Schwartzenberg, Adi Mor, Galia Luboshits et al.Regulatory T-cells (Treg) are a recently defined subset of CD4+ cells that can suppress inflammation and induce tolerance. Phenotypically, T-regs are characterized by a high level of expression of the IL-2 receptor alpha chain, CD25. Endothelial progenitor cells (EPCs) can transform into mature endothelial cells and promote vessel formation by inducing postnatal angiogenesis and vasculogenesis. Herein, we tested the hypothesis … …American Journal of Immunology, Vol. 1, Issue 4 · 31 Dec 2005 · 6,902 accessesView PDF Cite
