Fruit quality and its appearance are very important from consumer’s view point. The fruits of ‘Moro’, ‘Tarocco’, ‘Sanguinello’, and ‘Sanguine’ blood orange cultivars were harvested at the stage of commercial maturity in Kotra (North) and Darab (South) counties in Iran. After harvesting, the fruits were analyzed for Hunter value, total soluble solids (TSS) content, titratable acidity (TA), and concentrations of anthocyanin and cyanidin 3-glucoside. ‘Tarroco’ fruits from Darab region showed high Hunter L value (70.3). The oranges harvested in Kotra had a hue angel value of more than 80. Chroma values were at the highest amount in ‘Tarocco’ with 70.6 values. Generally, TSS was higher in the cultivars grown in south than north. ‘Sanguinella’ and ‘Sanguine’ fruits had the highest TA in both regions. Cyanidin 3-glucoside contents of ‘Tarocco’ (South) and ‘Moro’ (North) were 368.2 and 196.05 ㎎ㆍL?¹, respectively, which were higher than the others. However, ‘Sanguinello’ and ‘Sanguine’ fruits grown in the southern region contained higher amount of cyanidin 3-glucoside than those in the northern area. In this experiment, we found that climate was the major influence on main component and anthocyanin of fruits. ‘Tarocco’ and ‘Moro’ fruits had high quality in south and north counties, respectively.

Genetic improvement of plants need a high genetic diversity and molecular markers offer a powerful tool for its assessment. Poa pratensis has extensive divergence in natural old turfs and pastures in temperate zones of Iran,being useful for breeding programs. In this research, RAPD markers were used to study the genetic diversity of 19turfgrass genotypes (including 16 genotypes of Poa pratensis along with one genotype from each of Lolium perenne,Cynodon dactylon and Festuca arundinacea species). After screening 100 random 10-mer RAPD primers, 17 primers were selected based on the clarity of their amplified fragments in PCR and the high reproducibility for scoring. From the 284 produced bands, 281 were polymorphic. Cluster analysis of RAPD data was performed using the UPGMA method based on Jaccard's similarity coefficients. Dendrogram at a similarity of 0.24 gave 5 main clusters. The correlation coefficient between the data matrix and the cophenetic matrix of cluster data was high (r = 0.99), indicating that the clustering dendrogram being highly fitted to similarity matrix. A relatively high genetic similarity was observed between some commercial cultivars and Iranian local genotypes. In addition, this research showed the high genetic diversity among studied genotypes as well as the high efficiency of RAPD markers for evaluation of genetic diversity among turfgrasses.

Background: HER2/neu, a member of EGFR family, is over expressed in some tumors. The purpose of this study was to determine the salivary level and tissue expression of HER2/neu in patients with head and neck squamous cell carcinoma (HNSCC) and any correlation with clinicopathologic parameters. Methods: An enzyme-linked immunosorbent assay (ELISA) was used to evaluate the salivary level and immunohistochemistry (IHC) to assess tissue expression of HER2/neu in 28 patients with HNSCC and 25 healthy controls. Results: The salivary levels of HER2/neu in HNSCC patients was not significantly higher than in the healthy controls (p>0.005). There was no apparent correlation in salivary HER2/neu level with clinicopathological features such as age, sex, grade, tumor size and nodal status. All HNSCC specimens were positive (membranous or/and cytoplasmic) for HER2/neu, except one sample. Only one HNSCC specimen was stained in cytoplasm purely. All control specimens were membranous and cytoplasmic positive for HER2/neu. There was a significant difference between cytoplasmic staining in case and control groups (p-value<0.05). Conclusion: In our cases, no overexpression of HER2/neu was observed. Thus, our findings suggested that the use of Her-2 as a salivary marker of HNSCC cannot be recommended.

Background: Head and neck SCC is a common cancer related to various factors. IL-10, a pleiotropic cytokine produced by macrophages, T-helper-2 cells, and B lymphocytes, is thought to play a potential pathogenetic or therapeutic role in a number of human conditions, such as inflammation, autoimmunity and cancer. The present study was designed to evaluate the relation between tissue expression, serum and salivary levels of IL-10 in head and neck squamous cell carcinomas (HNSCCs) and their correlation with clinicopathologic features. Materials and Methods: Samples were collected from 30 patients with HNSCCs and 24 healthy volunteers. IHC analysis was used to examine the tissue expression and ELISA was employed to measure serum and salivary levels. Results: Our study showed tissue expression of IL-10 to be significantily higher in patients (P: 0.001), but there was no relation between tissue expression, serum and salivary levels of the marker (P>0.05). Also except for a positive correlation between tissue expression of IL-10 and stage (P: 0.044), there was no relation between this marker and clinicopathologic features. There was no correlation between serum and salivary levels in either patients or controls. Conclusions: It seems there is no correlation between level of IL-10 in serum and saliva and this marker in saliva and serum does not reflect tissue expression.
