Research ArticleOpen accessIn the abstractDetection and Localization of Anti and Pro-apoptotic mRNA Genes in Human Colorectal Cancer Using in situ RT-PCRMohd. Nazil Salleh, Boo Siaw Shi, Wan Khairuzzaman Wan Ramli et al.Problem statement: Recent studies using conventional Polymerase Chain Reaction have shown that anti-apoptotic (Cyclooxygenase-2, COX-2 and Nuclear Factor-κB, NF-κB) and proapoptotic mRNA (Bax and Bad) are involved in the tumorigenesis of colorectal cancer. The aim of this study was to localize the expression of anti and pro-apoptotic mRNA genes using Reverse Transcription in situ Polymerase Chain Reaction (RT in situ … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 7,441 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMutagenic Screening of Crude Oil Fractions Using Modified Ames Test and Allium cepa (Linn) AssayOlufunsho Awodele, Alade Akintonwa, Sunday O. Olayemi et al.Problem statement: Crude oil which may be broadly characterized as paraffinic or naphthenic is a complex mixture of alkanes, cycloalkanes and aromatic hydrocarbons. About 500,000 workers are employed in crude oil exploration and production worldwide. There have been reports of occupational exposure during drilling, pumping and transportation of crude oil, including maintenance of equipment used for these processes. Thus, skin … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 1 · 31 Jan 2010 · 8,629 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAutomated Breast Cancer Diagnosis based on GVF-Snake Segmentation, Wavelet Features Extraction and Neural Network ClassificationAbderrahim Sebri, Jihène Malek, Rached TourkiBreast cancer accounts for the second most cancer diagnoses among women and the second most cancer deaths in the world. In fact, more than 11000 women die each year, all over the world, because this disease. The automatic breast cancer diagnosis is a very important purpose of medical informatics researches. Some researches has been oriented to make automatic the diagnosis … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 7,407 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRole of AP-1 Antagonism in Growth Inhibition of Cervical Cancer Cell Lines by RetinoidsShennan Lu, Doris M. BenbrookRetinoid compounds induce multiple molecular effects that need to be taken into consideration in the development of theses agents as pharmaceuticals for cancer chemoprevention. Inhibition of cancer cell growth by retinoids is thought to occur through at least two mechanisms of transcriptional regulation resulting from direct binding of retinoids to nuclear retinoid receptors (RARs and RXR’s). First, the nuclear receptors … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 3 · 30 Sep 2006 · 7,477 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhysical Basis of Magnetic Resonance Spectroscopy and its Application to Central Nervous System DiseasesNicolás Fayed, Salvador Olmos, Humberto Morales, Pedro J. ModregoMagnetic Resonance Spectroscopy is based on the chemical shift property of the atom nuclei when a magnetic field is applied. This technique offers invaluable information about living tissues with special contribution to the diagnosis and prognosis of the central nervous system diseases. Concentration of several metabolites can be assessed in a reproducible manner by means of modern clinical scanners. N-acetyl-aspartate … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 7,851 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRole of Cytokines in the Regulation of Glioma Tumour Growth and AngiogenesisChristina Piperi, Athanasios Zisakis, Robert W. Lea, Anastasios KalofoutisMalignant glioblastomas are the most common type of primary brain tumors accounting for more than 50% of all intracranial gliomas. Due to their aggressive nature, recurrent growth, and their extremely poor prognosis for survival, research approaches have made little progress in advancing treatment of these tumours which have the ability of both modulating host immune function and neutralizing immune-based therapies. … …American Journal of Immunology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,868 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImmunofluorometrical Exploring of Cortisol Hormone Levels in the Serum of Patients with Histologically Verified Microcellular Lung CancerIvan MilosevicIt is already known in the science that the cells of microcellular lung cancer can produce ACTH. By following the levels of Cortisol as one consequence of ACTH producing, in the serum of microcellular lung cancer patients, we could make some statistical conclusions how significant these levels would be in eventual future early diagnostic procedures, besides already existing tumormarkers etc. … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,177 accessesView PDF Cite
