Address correspondence to [email protected] ABSTRACT A very simple strategy for preparing hierarchical inorganic nanostructures under ambient aqueous conditions is presented. The hierarchical inorganic nanomaterials were obtained by simply adding a highly concentrated solution of one reactant to a solution of another reactant with low concentration. No surface-capping molecules or structure-dire...

In the present study, the potency and immunogenicity of the inactivated bivalent vaccine of Newcastle disease (ND) and avian influenza (AI) produced by Razi institute in Iran were compared with a similar imported vaccine administered by standard methods to specific-pathogen-free (SPF) chicken. A total of 150 twenty-one-day-old SPF chickens were used for evaluating Razi and imported inactivated ...

Antigen and vaccine banks are stocks of immunogenic materials ready to be formulated into vaccines (bulk antigens) or ready to use (vaccines) in case of need by one or more of the parties of the bank. These stocks were primarily developed by foot and mouth disease [FMD] free European countries to control unexpected severe FMD episodes after the cessation of routine vaccination in the 1990s. For...

We show that differences in the quality of labor relations across countries can help to explain cross-country differences in ownership concentration. Controlling for minority shareholder protection, countries in which labor relations are hostile tend to have more concentrated ownership than countries in which labor relations are cooperative. Union strength, labor regulation, and the political o...

A stable B.C.G. vaccine, prepared and distributed in the freeze-dried form, is now accepted for use in many parts of the world. Recent trials (Medical Research Council, 1958, 1960; Griffiths and Gaisford, 1956) have confirmed that the freeze-dried vaccine induces a high degree of tuberculin sensitivity without untoward local reactions. From its stability the freeze-dried vaccine has undoubted a...

Introduction: Epidermal growth factor receptor (EGFR) has been shown to play a critical role in tumor cell growth and its overexpression has been observed in many epithelial tumors. In the field of cancer vaccine research, displaying the peptide mimotope on the surface of phage particles has shown promising results. Methods: In this study using m13-PVIII phage display system, two constructs we...

introduction: hepatitis c virus (hcv) is one of the major medical problems. human and chimpanzees are the only specific hosts which are naturally susceptible to hcv infection. mice and other common laboratory animals are resistant to the virus, hence hcv prophylactic and therapeutic researches are very difficult and challenging. hcv non-structural protein 3 (ns3) is one of the most attractive t...

Background: Immunization against diphtheria, tetanus and pertussis has been applied in Iran since 1950. WHO suggests periodical evaluation of effectiveness of the triple diphtheria-tetanus-whole cell pertussis (DTwP) vaccine, worldwide. Objectives: To determine the immunogenicity of locally manufactured DTwP vaccine administered to preschool children in a number of health centers of Tehran in 2...
