Research ArticleOpen accessIn the abstractRedox Sensing and Cardiac Myocyte Loss: Some Recent InsightsShyamal K. GoswamiGeneration of reactive oxygen-nitrogen species (ROS/RNS) has long been ascribed to pathophysiological conditions like ageing, neurodegenerative and cardiovascular disorders. However, more recent evidences suggest that while generation of ROS/RNS at a higher threshold is deleterious, at a lower dose these can act as second messengers, influencing specific cellular events like cell growth and differentiation, embryonic development, protection against ischemic injuries … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 6,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractPharmacophore Pattern Identification of Tachykinin Receptor Selective Peptide Agonists: Implications in Receptor SelectivityAnjali Dike, Indu R. Chandrashekaran, Anil K. Mantha et al.The mammalian tachykinin (TK) peptides and their three Neurokinin (NK1, NK2 and NK3) receptors represent an effector system with wide-ranging actions on neuronal, airway smooth muscle, mucosal, endothelial, immune, inflammatory and remodeling cell function. Recent clinical and preclinical data suggests the pathophysiological role of TKs in various diseases including asthma, emesis and depression. The TK-NK receptor interactions and overlapping functions … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 6,693 accessesView PDFCite
Research ArticleOpen accessIn the abstractFine Needle Aspiration Cytology Evaluation for Classifying Breast Cancer Using Artificial Neural NetworkNor Ashidi Mat Isa, Esugasini Subramaniam, Mohd Yusoff Mashor, Nor Hayati OthmanThirteen cytology of fine needle aspiration image (i.e. cellularity, background information, cohesiveness, significant stromal component, clump thickness, nuclear membrane, bare nuclei, normal nuclei, mitosis, nucleus stain, uniformity of cell, fragility and number of cells in cluster) are evaluated their possibility to be used as input data for artificial neural network in order to classify the breast precancerous cases into four … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 7,156 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Analysis of Death Using the National Longitudinal Mortality StudyMark GiusUsing an expansive survey of death that includes not only socioeconomic and demographic information on a deceased person, but also his or her cause of death, the present study attempts to examine the determinants of death. The present study uses the National Longitudinal Mortality Study, Public Use File (NMLS), which contains data on 370,930 individuals over the age of 24, … …Journal of Social Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,879 accessesView PDFCite
Research ArticleOpen accessIn the abstractFeature Selection in Data-Mining for Genetics Using Genetic AlgorithmV. N. Rajavarman, S. P. RajagopalanWe discovered genetic features and environmental factors which were involved in multifactorial diseases. To exploit the massive data obtained from the experiments conducted at the General Hospital, Chennai, data mining tools were required and we proposed a 2-Phase approach using a specific genetic algorithm. This heuristic approach had been chosen as the number of features to consider was large (upto … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,630 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vivo Anti-malarial Tests of Nigella sativa (Black Seed) Different ExtractsH.A.A. Abdulelah, B.A.H. Zainal-AbidinNigella sativa (black seed) seeds have been used as a traditional medicine for the treatment of a variety of sicknesses including parasitic diseases. Intraperitoneal and oral administrations of ethanol, chloroform and aqueous seed extracts (50, 100, 200 and 400 µL kg-1) of N. sativa, were screened in the 4-day suppressive assays for their anti-malarial properties against Plasmodium berghei in mice. … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 2 · 30 Jun 2007 · 8,499 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecent Advances in the Synthesis of Artificial Antigen and Its Application in the Detection of Pesticide ResidueTong Dewen, Hesheng Yang, Wang JinyiRecent advances in the research of artificial antigen have shown that artificial antigens can be valuable approach for the treatment of some diseases as well as the detection of pesticide residues. By directly/indirectly coupling hapten to an appropriated carrier (macromolecule), artificial antigen can induce animals to produce hapten-specific antibody. Based on this principle, various vaccines have been developed. More impotently, … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 7,617 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneration of Five New Musa Hybrids With Resistance To Black Sigatoka and High YieldRicardo Hernández, Teresa Ramírez, Juan Carlos Noa-Carrazana et al.The ability to identify genetic variation is indispensable to effective management and use of genetic resources. This work is the first approach concerning to generation and genetic differentiation of new Musa hybrid lines obtained in INIVIT (Cuba), crossing Musa acuminata male diploid (AA) x female triploid (ABB), genotypes selected by their resistant character to pests and diseases. From the obtained … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 8,813 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Ethanol Extract of Vinca rosea on Wound Healing in Diabetic RatsShivananda NayakVinca rosea (Catharanthus roseus L.) is native to the Caribbean Basin and has historically been used to treat a wide assortment of diseases. European herbalists used the plant for conditions as varied as headache to a folk remedy for diabetes. The objective of the study is to evaluate the diabetic wound healing activity of Vinca rosea using the excision wound … …OnLine Journal of Biological Sciences, Vol. 6, Issue 2 · 31 Dec 2006 · 7,422 accessesView PDFCite
Research ArticleOpen accessIn the abstractBehaviour Patterns of the Pine Processionary Moth (Thaumetopoea wilkinsoni Tams; Lepidoptera: Thaumetopoeidae)Ahmad Houri, Dany DoughanThaumetopoea wilkinsoni is a serious pest of pine trees, especially the wide-spread Pinus brutia. This infestation has a significant economic impact both in the loss of forest wood growth and in medical expenses for treating related human diseases. This paper presents a detailed study of the behaviour patterns of the moth stage in an attempt to identify best control methods. … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 1 · 31 Mar 2006 · 8,700 accessesView PDFCite
