Diploid and continuous cell lines are used to propagate viral vaccines. At Human Viral Vaccine Department of Razi Vaccine and Serum Research Institute, MRC5 diploid cell is used for the development of live attenuated measles, mumps, rubella, and three types of poliovirus vaccines.  Additionally, three continuous cell lines (i.e., RK13, HeLa, and Vero) are applied in quality control tests. Accor...

In-house cocoa flour RMs instead of CRMs were prepared and checked for its homogeneity and stability. Due to CRMs limited availability in terms of matrices of concern and high production cost when making in-house cocoa flour, RMs are alternatively used for daily quality control in the laboratory. The analysis method for reliable checking of homogeneity and stability of cadmium content in the in...

The aim of the study was to assess the level of air pollution by volatile organic compounds (VOCs) in a pig fattening house and in its vicinity. Air samples for chromatographic analysis were taken in the fattening house and in the vicinity of the farm. The air quality study shows that the level of organic gaseous pollutants was twice as high in the fattening house as in the atmospheric air. Alm...

the study was conducted to determine the effect of varying protein levels and preservation method on external egg qualities of japanese quails. a total of 180 birds were randomly allotted into three dietary treatments in a completely randomized design (crd) replicated six times. a factorial arrangement of 3 × 4 × 4 which involves 3 protein levels (15, 20 and 25% crude protein), 4 storage method...

BACKGROUND Although many patients with allergic rhinitis have symptoms due to sensitization to more than one kind of allergens, and mixed allergen extracts are widely used for immunotherapy, there are few published trials. OBJECTIVE Our study aimed to evaluate the effect of multiple-allergen immunotherapy on improving the symptoms and quality of life of allergic rhinitis patients. METHODS W...

ABSTRACT The proponents of digital cinema seek picture quality exceeding that of the best film-based presentation. Quantifying the performance of systems for the presentation of high quality imagery presents several challenges. For example, the dynamic range and the resolution may not be simply related to the nominal characteristics of bit-depth and pixel counts. We review some of the measureme...

As house size increases, resource use in buildings goes up, more land is occupied, increased impermeable surface results in more storm-water runoff, construction costs rise, and energy consumption increases. In new, single-family houses constructed in the United States, living area per family member has increased by a factor of 3 since the 1950s. In comparing the energy performance of compact (...

Quality has been a major driving factor for software consumption. This has been seriously compromised among software developers especially in small scale software outfits in developing countries such as Nigeria. The Software development process in these software houses needs to be re-engineered in order to improve the quality of software being produced and to meet the global demand on quality s...
