Research ArticleOpen accessIn the abstractIs Wright Test an Appropriate Screening Test for Diagnosis of Brucellosis?Behzad Mohsenpour, Shahla Afrasiabian, Katayoon Hajibagheri, Ebrahim GhaderiProblem statement: Diagnosis of brucellosis is generally based on culture, polymerase chain reaction and serology. The first two methods are not accessible in all parts of world and are expensive. The routine method for diagnosis of brucellosis is considering Wright test as the first screening test; if the results are Wright positive’ Wright would be the next choice otherwise 2ME … …American Journal of Infectious Diseases, Vol. 7, Issue 2 · 17 Sep 2011 · 16,762 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGenetic Polymorphism Exon 9-11 at the Leptin Gene Receptor in Breeder Hens of Mazandaran Native FowlsHossein Ali Abbasi, Shahabodin Gharavysi, Rohullah AbdullahpourProblem statement: Leptin a 16 kD protein synthesized by white adipose tissue and involved in regulation of feed intake, energy balance, fertility and immune function. In order to evaluate the leptin gene receptor polymorphism, we have used a Restriction Fragment Length Polymorphism (RFLP) method. Approach: Blood samples were collected from randomly chosen 100 native fowls breeding station of Mazandaran. The … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 17 Sep 2011 · 7,700 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSome Effects of Abiotic Stress on Infection of Dyer’s Woad (Isatis tinctoria L.) by Puccinia thlaspeos C. Schub.: Implications for Biological ControlElizabeth Thomas, Bradley Ray KroppProblem statement: The rust pathogen, Puccinia thlaspeos, is being studied as a potential biocontrol agent for the noxious weed dyer’s woad. Although its disease etiology is well understood, very little has been learned about the effect of environmental stresses on infection. Approach: Dyer’s woad plants were exposed to different levels of oxidative stress, salinity stress, osmotic stress, dehydration, and cold … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,715 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDNA Polymorphism of Bovine Pituitary-Specific Transcription Factor and Leptin Gene Between Iranian Bos indicus and Bos taurus CattleArash Javanmard, Nader Asadzadeh, Fatollah SarhadiProblem statement: Variations at DNA level contribute to the genetic characterization of livestock populations and this may help to identify possible hybridization events as well as past evolutionary trends. Approach: The leptin and Pit-1 are attractive candidate genes for production and reproduction traits in cattle. A total of 247 Animals from four breeds from two species of Iranian cattle populations … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,024 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTransgenic Indian Cotton (Gossypium hirsutum) Harboring Rice Chitinase Gene (Chi II) Confers Resistance to Two Fungal PathogensM. Ganesan, P. Bhanumathi, K. Ganesh Kumari et al.Problem statement: The present investigation described a simple and reproducible protocol for transgenic cotton regeneration and characterization of chitinase (Chi II) gene expression against two different fungal pathogens in cotton. Approach: Transgenic cotton (Gossypium hirsutum cv. SVPR2) plants were produced by pCambia-bar-Chi II (13.8 kb) under the control of the CaMV 35S promoter, harbored in the strain LBA 4404 Agrobacterium … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 2 · 30 Jun 2009 · 8,531 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGenetic Diversity of Red Chittagong Cattle Using Randomly Amplified Polymorphic DNA MarkersMohammad Masud Rana Mufti, Mst. Parvin Mostari, Gautam Kumar Deb et al.Problem statement: Red Chittagong Cattle (RCC) is a potential genetic resource in Bangladesh having dairy potentialities, high resistance to disease and survive harse environmental condition while require low input supply. This resource is now disappearing due to indiscriminate crossing with other local and exotic cattle. To conserve this resource, find out the genetic diversity of RCC is prime concern. Approach: … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 1 · 17 Mar 2009 · 8,680 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIdentification of Methicillin Resistant Staphylococcus aureus (MRSA) and Methicillin Resistant Coagulase-Negative Staphylococcus (CoNS) in Clinical SettingsM.A. Shorman, A.M. Atoom, N.M. Abuharfeil, A.M. Al-MajaliTo evaluate different methods for the identification of methicillin-resistant Staphylococci and their reliability, 112 Staphylococcal isolates (32 Staphylococcus aureus isolates and 80 coagulase negative Staphylococci isolates "CoNS") were collected from 118 nasal swab cultures and were subjected to three methods to detect oxacillin susceptibility of the isolates. The three methods were oxacillin disk diffusion method; the Epsilometer- test (E-test) and … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 7,972 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHIV-1 Infection and Central Monoamine NeurotransmittersAdarsh M. Kumar, J. B. Fernandez, Irina Borodowsky et al.Human immunodeficiency virus type 1 (HIV-1) enters the central nervous system (CNS) shortly after infection and gets localized in different brain regions, leading to various types of neuropathological problems. It has been hypothesized that HIV-1 infection mediated neuropathogenesis may also adversely affect the activity of the central monoamine neurotransmitters systems, such as dopamine (DA), and 5-hydroxytryptamine (5-HT, serotonin), resulting in … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,491 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPlatelet Derived Growth Factor-A mRNA Levels in Diabetic and Nondiabetic Subjects at Risk of Coronary Heart DiseaseSalman A.H. AlrokayanCoronary heart disease (CHD) is the number one cause of death in developed countries. We investigated the quantity of platelet derived growth factor-A mRNA (PDGF-A mRNA) among four different groups of diabetic and nondiabetic Saudi subjects (n = 40) at risk of CHD. Total RNA was derived from peripheral blood mononuclear cells (PBMN) and PDGF-A mRNA reverse transcribed into cDNA … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 6,676 accessesView PDF Cite
