Research ArticleOpen accessIn the abstractGeographic Distribution and Genetic Analysis of Physiological Racesof Setosphaeria turcica in Northern ChinaJingao Dong, Yongshan Fan, Xiumei Gui et al.Five hundreds and forty-six isolates of Setosphaeria turcica, the causal agent of Northern Corn Leaf Blight, were collected in 61 corn-growing locations throughout six provinces of Northern China during 2000-2002, to determine their pathogenicity on two sets of host differentials: OH43/Huangzao4, OH43Ht1Huangzao4Ht1, OH43Ht2/Huangzao4Ht2, OH43Ht3/Huangzao4Ht3 and OH43HtN/Huangzao4HtN. The isolates were grouped into 13 different physiological races (0, 1, 12, 3, 13, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,806 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiochemical and Genetic Responses of Fungi to the Toxic Effect of Synthetic and Natural FungicidesMarÍa-Elena Báez-Flores, Rosalba Troncoso-Rojas, Martin-Ernesto Tiznado-HernándezThe objective of the present review is to analyze the molecular basis of fungicide resistance mechanism to both synthetic fungicides and the natural fungicides isothiocyanates. The review is focused mainly on Alternaria sp., but whenever available, similar studies in other fungi have been included. Fungal resistant strains to dicarboximide and phenylpyrrole fungicides have been found to contain mutations in one … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,118 accessesView PDFCite
Research ArticleOpen accessIn the abstractChromium Picolinate did not Effect on the Proliferation and Differentiation of MyoblastsM.C. Tsa, T.F. LienThis experiment is conducted in vitro to investigate trivalent chromium picolinate affects the proliferation and differentiation of myoblasts. A myoblasts cell line (C2C12) from rats was used in the experiment. These were randomly divided into the control group, the Pic group (50ppb picolinate) and the CrPic group (50ppb chromium picolinate). The differentiation of myoblasts reveals that the number of differentiated … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 6,414 accessesView PDFCite
Research ArticleOpen accessIn the abstractQTL Mapping Using Multiple Markers SimultaneouslyD. Kolbehdari, J.A.B. RobinsonMethods for detecting and locating a single QTL within a 10 cM region of DNA using 10 equally spaced SNP markers were compared. The QTL was assumed to be bi-allelic and located between markers 5 and 6. Monte Carlo simulation of a granddaughter design with 30 sires and 400 sons was used. Linear regression nested within sire using either two … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 7,110 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Heat Shock Transcription Factor Family in Entamoeba histolyticaConsuelo G. García, Ma. De la Luz Macias Argüelles, D. Guillermo P Ishiwara et al.The HSTF is a master molecule involved in the transcriptional control of several genes during different types of stress. This transcription factor is a very conserved protein identified in different organisms from bacterial to human. Entamoeba histolytica is the protozoan responsible for the human amoebiasis. This parasite is exposed to different kind of stress as changes in the pH, temperature, … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmetine produce Entamoeba histolytica Death by Inducing a Programmed Cell DeathJ.D. Villalba-Magdaleno, R. Rojas, C. Gómez et al.Amoebiasis is a major public health problem in tropical and subtropical countries. Although a number of antiamoebic agents are used for its treatment and the molecular targets of these drugs have been identified, the biochemical and physiological mechanisms that produce trophozoite death are little known. The present study dates the in vitro induction of programmed cell death (PCD) in E. … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,211 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevalence of Human Papillomavirus Types Among Mexican Women with Intraepithelial Lesions and Cervical Cancer: Detection with MY09/MY011 and GP5+/GP6+ Primer SystemsGloria Fernández-Tilapa, Berenice Illades-Aguiar, Dinorah Nashely Martínez-Carrillo et al.Squamous cervical carcinoma (SCC) is the most common cancer found in Mexican women. Human papillomavirus (HPV) infection is a prerequisite for this disease. In Mexico little is known about the prevalence of HPV-types and knowledge of the circulating genotypes by region is limited. The aim of this study was to determine the prevalence and genotypes of HPV in biopsies from … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractExpression of Toll-like Receptors (TLRs) and Nucleotide-binding Oligomerization Domain (NODs) in murine peritoneal macrophages on in vitro treatment with Thymosin α 1Shikha Tarang, Ajit SodhiThymosin α 1 (Tα1) treatment of murine peritoneal macrophages in vitro induces the expression of TLRs and Nod2 proteins. Enhanced expressions of TLR2, -4, -5, -6, -7, -8, -9 and Nod2 were observed by RT-PCR and western blotting. Expression of downstream signaling molecules - MyD88, IRAK1, TRAF6, IRF3 were also up regulated on treatment with Tα1. It was also observed … …American Journal of Immunology, Vol. 3, Issue 1 · 30 Jun 2007 · 7,150 accessesView PDFCite
Research ArticleOpen accessIn the abstractToll-Like Receptor (TLR) 2 and TLR4 Gene Expression in Canine HeartA. Linde, F. Blecha, T. MelgarejoToll-like receptors (TLRs) are archetypal pattern recognition receptors of immediate importance for an efficacious innate immune response. TLRs exhibit marked differential tissue activity and their levels within a discrete cell type can be highly dynamic. Of 13 known mammalian paralogues, three TLRs have been identified in the dog. Although cardiac TLR expression has been reported in other species, this study … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 6,921 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvidences of Apoptosis in Hepatitis C Virus-Infected Hepatocytes and Peripheral Blood Monocuclear Cells in the Absence of Liver InjuryViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.Understanding the mechanism of Hepatitis C Virus (HCV) pathogenesis is an important part of HCV research. In this study, the presence of apoptosis in HCV-infected liver and Peripheral Blood Mononuclear Cells (PBMC) from patients positive for anti-HCV antibodies and negative for serum HCV-RNA was investigated.
