The ice cream is consumed in abundance due to its high nutritional value and flavor, According to neutral pH and abundant nutrients, ice cream is a suitable environment for microbial growth. Some ice cream ingredients such as milk and egg can be contaminated with pathogenic microorganisms such as salmonella. Therefore ice cream consumption can cause food poisoning. The aim of this study was to determine the salmonella contamination of traditional ice creams in Zabol city. In this descriptive-analytical study in 2015 years , 90 traditional ice cream samples were collected from different shops of Zabol city and then in sterile conditions were transferred to food laboratory food and microbiological tests were performed on samples In this study, 62 samples (68.8%) of 90 collected ice cream samples, were found positive for Salmonella. Salmonella contamination is prevalent in ice creams in Zabol. Main causes of contamination are using of unpasteurized milk, lack of attention to hygienic issues and lack of proper washing of dishes.So more accurate monitoring of ice cream shops in Zabol are required.

Background and Objectives Snowball sampling is applied when samples with the target characteristics are not easily accessible. This research describes snowball sampling as a purposeful method of data collection in qualitative research. Methods This paper is a descriptive review of previous research papers. Data were gathered using English keywords, including “review,” “declaration,” “snowball,” and “chain referral,” as well as Persian keywords that are equivalents of the following: “purposeful sampling,” “snowball,” “qualitative research,” and “descriptive review.” The databases included Google Scholar, Scopus, Irandoc, ProQuest, Science Direct, SID, MagIran, Medline, and Cochrane. The search was limited to Persian and English articles written between 2005 and 2013. Results The preliminary search yielded 433 articles from PubMed, 88 articles from Scopus, 1 article from SID, and 18 articles from MagIran. Among 125 articles, methodological and non-research articles were omitted. Final...

Background & Objective: Lipoma (a benign tumor composed of adipose tissue) is the most common benign mesenchymal tumors in soft tissue but it is very rare in the parotid gland. Case: We reported a 54 years old man with parotid gland lipoma. Parotid gland lipoma usually originates from the superficial lobe. Superficial parotidectomy has been considered as the choice method of the treatment. Result: lipoma, as a prevalent tumor of the soft tissue, is rarely seen in salivary glands.

The recent availability of the complete genome sequences of a large number of model organisms, together with the immense amount of data being produced by the new high-throughput technologies, means that we can now begin comparative analyses to understand the mechanisms involved in the evolution of the genome and their consequences in the study of biological systems. Phylogenetic approaches provide a unique conceptual framework for performing comparative analyses of all this data, for propagating information between different systems and for predicting or inferring new knowledge. As a result, phylogeny-based inference systems are now playing an increasingly important role in most areas of high throughput genomics, including studies of promoters (phylogenetic footprinting), interactomes (based on the presence and degree of conservation of interacting proteins), and in comparisons of transcriptomes or proteomes (phylogenetic proximity and co-regulation/co-expression). Here we review th...
