cucumber mosaic virus (cmv) is one of widely-spread viruses of plants with the broadest host range encompassing over 1200 species. one major limiting factor for detection of the virus is unavailability of the virus-specific antibodies especially in developing countries. recombinant dna technology facilitates antibody preparation without requiring special equipment. in this study, coat protein (...

Six hundred and forty one-day-old Cobb male broilers were used to evaluate ornithine decarboxylase (ODC) expression in the mucosa of the small intestine. Birds were submitted to early feed restriction from 7 to 14 days of age. The provided feed was supplemented with glutamine. A completely randomized design with a 2 x 2 factorial arrangement was used (with or without glutamine, with or without ...

Background: Despite highly effective treatments to cure hepatitis C, almost 80% of chronically HCV-infected people are not treated, as they unaware their infection. Diagnostic rates and linkage care must be substantially improved reverse this situation. The HCV core antigen (HCVcAg) is a conserved protein that can detected in the blood patients indicates active Aim: To produce murine monoclonal...

The sensitivity of digoxigenin and biotin labelled DNA probes for the detection of human papillomavirus (HPV) by dot blotting and in situ hybridisation was compared in tissues from cervical, laryngeal, and anogenital neoplasia. Probes were either labelled with digoxigenin by the random primer technique and detected with anti-digoxigenin antibody, or labelled with biotin by nick translation and ...

We studied the presence of immunoglobulin G (IgG) in equid fossil bones from Venta Micena (Granada, Spain), dated at 1·6 Myr old, and from Atapuerca (Burgos, Spain) (0·12 Myr), and in ostensibly hominid fossils VM1960 and VM3691 (1·6 Myr) from Venta Micena and CV1 and CV2 (1·4 Myr) from Cueva Victoria (Murcia, Spain). Samples taken from the specimens were crushed to a fine powder and their mine...

Objective: To construct and identify recombinant expression of a therapeutic tumor vaccine with HBcAg as a vector. Methods: PCR primers were designed according to the gene sequences of restriction enzyme sites of recombinant pKK233.2-hepatitis B core antigen (HBcAg) and melanoma-associated antigen 3 (MAGE-A3: 112120aa). The target fragment of MAGE-A3 was synthesized and cloned to pKK233.2-HBcAg...

Monoclonal antibodies (MoAbs) were generated following immunization of Balb/C mice with adenovirus type 5 grown in Hep2 cell line. Six clones reactive to hexon antigen of the virus were stabilized, of which 4 had mu-heavy chain specificity and 2 were of gamma-heavy chain type. Three of the clones (ADV-1, ADV-3 and ADV-5) had a high ELISA reactivity to the hexon antigen but exhibited differentia...

Background & Aims: Toxoplasma gondii is an obligate, intracellular parasite, which is widely spread in the world. The parasite is able to infect all warm-blooded hosts including humans and farm animals. The infection in humans often occurs after the ingestion of raw or undercooked meat containing tissue cysts. Several methods have been applied to detect this parasite in contaminated foods. Reco...

BACKGROUND C-Phycocyanin (C-PC) from blue-green algae such as Spirulina has been reported to have various pharmacological characteristics, including anti-inflammatory and anti-tumor activities. Recombinant β-subunit of C-PC (C-PC/β) is an inhibitor of cell proliferation and an inducer of cancer cell apoptosis. OBJECTIVES Since C-PC/β has a big potential to be used as a promising cancer prevent...

Histological Analysis and Immunohistochemistry Renal sections (3 μm thick) were stained with periodic acid-Schiff (PAS) and examined under light microscopy. Glomerulosclerosis index was semiquantitatively graded as 0 to 4+; vascular injury score as 0 to 3+; and tubulointerstitial injury score as 0 to 5+, according to the criteria reported previously. Ultrastructure of glomerular podocytes was a...
