background and purpose: water is the most important limiting factor of sustainable development. poor quality of water sources and lack of appropriate management in some regions are the main reasons of water crises in the country. this study was conducted to assess water sources quality and the trend of their change in rural area of sabzevar county in a five year period. materials and methods: i...

A total of 57 brands of commercially available hair and skin care cosmetics manufactured in Jordan were evaluated for their microbiological quality using standard procedures. Viable microorganisms were not recovered from 56.1% of the items tested and approximately 5.3% harbored less than 102 CFU g 1. Dominant bacterial isolates were Bacillus species, Pseudomonas spp., and coagulase-negative sta...

The introduction of 2-[18F] fluor-2-deoxy-D-glucose (18FDG) has provided a valuable tool for the study of glucose metabolism in both normal and diseased tissue in conjunction with positron emission tomography (PET). 18FDG is the most important radiopharmaceutical to be used in Nuclear Medicine for studying the brain, heart and tumor. The advancement in synthesis and quality control of 18FDG and...

The performance of a multispectral imaging system has been evaluated in monitoring aerobically packaged beef filet spoilage at different storage temperatures (0, 4, 8, 12, and 16°C). Spectral data in the visible and short wave near infrared area (405-970nm) were collected from the surface of meat samples and correlated with microbiological data (log counts), for total viable counts (TVCs), Pseu...

Diverse land use activities can elevate risk of microbiological contamination entering stream headwaters. Spatially distributed water quality monitoring carried out across a 17 km(2) agricultural catchment aimed to characterize microbiological contamination reaching surface water and investigate whether winter agricultural land use restrictions proved effective in addressing water quality degra...

Introduction It is nearly 30 years ago that the International Commission on Microbiological Specifications for Foods (ICMSF) provided urgently needed guidance on the use of sampling plans and microbiological criteria for foods in international trade. With publications like “Microorganisms in Foods 2: Sampling for Microbiological Analysis: Principles and Specific Applications” (1) and now “Micro...

According to the World Health Organization (WHO) guidelines, "safe drinking-water must not represent any significant risk to health over a lifetime of consumption, including different sensitivities that may occur between life stages". Traditional methods of water analysis are usually complex, time consuming and require an appropriately equipped laboratory, specialized personnel and expensive in...

  The effect of gamma radiation (1, 3 and 5 kGy) on microbial quality of farmed rainbow trout (Oncorhynchus mykiss) fillets which were stored under frozen conditions (-20° C) was studied by measuring microbiological changes in 5 months. Gamma irradiation and increasing of frozen storage time had significant effects (P<0.05) on the reduction of microorganism's population. The total count showed ...
