Understanding dependence structure and relationship between two sets of variables is of main interest in statistics. When encountering two large sets of variables, a researcher can express the relationship between the two sets by extracting only finite linear combinations of the original variables that produce the largest CORRELATIONs with the second set of variables.When data are continuous functions of another variable (generally time), the methods of multivariate analysis cannot be applied to the data. Therefore, some theoretical justification is needed to provide the required definitions and concepts regarding the essential nature of the data. This leads to difining canonical CORRELATION for pairs of random functions called functional canonical CORRELATION (FCCA).If the data related to functional phenomena, are observed discretely, the first task is to convert these observations to appropriate curves. This is due to functional nature of the phenomena that the data related to. On the other hand, the functional quantity of interest may be measured with error. In such cases, we should first remove the observational error bay taking a smoothing procedure to account. In this paper, Iranian weather data, collected in 2006, are treated by using FCCA. The data set contains discret measurment’s of three phenomena: temperature, humidity and precipitation and was collected from 102 weather stations. we have fitted continuous curves to the original data, and then extrated the CORRELATION patterns between each pair of the three phenomena.

Based on the point of view of geometrical representation of an intuitionistic fuzzy set, we take into account all three parameters describing intuitionistic fuzzy set, propose a kind of new method to calculate CORRELATION and CORRELATION coefficient of intuitionistic fuzzy sets which is similar to the cosine of the intersectional angle in finite sets and probability space, respectively. Further, we discuss some of their properties and give three numerical examples to illustrate our proposed method reasonable.

Background & Objective: Thyroid hormones have an important role in the regulation of lipid metabolism. Subclinical hypothyroidism (SCH), defined as a mild increase in thyroid-stimulating hormone (TSH) and normal level of thyroxine (T4), could be associated with altered lipid profile. The current study aimed at assessing the association between SCH and changes in lipid profile.Methods: Data of 53 patients with SCH and 53 euthyroid cases were collected from Besat Hospital in Hamadan, Iran, in 2013. The age range of the cases was 18 to 60 years, and the groups were matched in terms of gender, age, and body mass index (BMI). SCH was defined as a TSH value of 4.2 to 10 mU/L, and normal T4 as 0.8 to 2.8 ng/dL. Control cases had a normal TSH ranging from 0.5 to 4.2 mU/L. The total serum cholesterol (TCHOL), high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride (TG) levels in both groups were examined and the results were recorded.Results: Participants with SCH had significantly higher LDL and lower HDL levels than the control group regardless of age group and gender (P-value<0.001), but there was no difference in TG and TCHOL levels (P-value<0.05). The prevalence of dyslipidemia and SCH was only significant in females (P-value=0.009). Totally, there was significant CORRELATION between the prevalence of dyslipidemia and SCH regardless of gender (P-value=0.04).Conclusion: SCH is associated with dyslipidemia, and biochemical screening for thyroid dysfunction is recommended in all patients with dyslipidemia.

Background: Preeclampsia is a disorder of pregnancy with increased maternal and perinatal morbidity and mortality. An imbalance between free radical induced lipid peroxidation and antioxidant system has been suggested as possible pathogenesis of preeclapsia. It has been shown CORRELATION of some serum antioxidant agents (for example ceruloplasmin) with preeclampsia and its severity. The purpose of this study was to evaluate of this CORRELATION.Methods: In a analytic case-control study, in clinic and delivery unit of Mirza Koochak Khan university hospital, Tehran, we evaluated 90 pregnant women of 19-38 years old with gestational age higher than 20 weeks in two groups, case (preeclampsia) and control (healty mother). Case group was devided into two groups; mild preeclampsia (n=30) and severe preeclampsia (n=30). Patients with preeclampsia (n=60) had either early (n=41) or late preeclampsia (n=19). Control group included 30 normotensive pregnant women. Serum Ceruroplasmin level was measured. Then relationship between this factor and preeclampsia was studied.Results: The mean level of serum ceruloplasmin in women with severe preeclampsia (390.83mg/dl) and mild preeclampsia (319.43mg/dl) was higher than control group (212.7mg/dl). Likewise it was significantly higher in severe preeclampsia than mild (P<0.001) and higher in early (373.28mg/dl) than late preeclampsi (298.34 mg/dl) (P<0.01).Conclusions: Our data suggest that serum ceruroplasmin level may predict preeclampsia occurrance and its severity. Likewise antioxidant theryapy before the onset of preeclampsia in an attempt to decrease its frequency should be considered.

Regarding discourse features, story-telling and way of thinking, Saadi's mind is of a symmetric nature. This, in itself, causes him to put his thoughts down clearly, logically, reasonably, and pleasurably. This article is about to examine dimensions of this subject in Saadi’s Gulistan. The symmetries we are studying include those symmetries available in the name of the chapters, the structure of the stories, the syntactic and semantic constituents, the characterizations, and finally the figures of speech such as antimetabole contrariety, meta-thesis, and simile. Based on the findings of this research, it is clarified that Saadi takes high advantage of different kinds of syntactic and semantic symmetries in the linguistic, semantic, stylistic and narrative level without letting it result in complexity. Saadi’s fervor for rhythmical and melodic prose could, also, be credited to his symmetrical mind. The subject at hand will be exemplified and clarified along this article through an optimal magnitude of examples extracted from Gulistan. It should be noted that except for some sporadic researches in this case, the subject hasn’t been directly come under the light of analysis so far. Consequently, there feels to be a critical must for further research on this case, as well.  

Background and Aim: One important function of leptin is the regulation of immune or inflammatory responses. Moreover, in a recent study no CORRELATION between leptin and periodontal diseases was found. Therefore the aim of this study is to determine the CORRELATION between leptin concentration and chronic periodontitis.Materials & Methods: In this analytical study, 20 healthy gingival tissue samples (control group) and 20 gingival tissues with advanced and moderate chronic periodontitis (case group) and 20 blood samples were taken from 20 patients. Patients were consisted of 55% females and 45% males with average age of 42. 25 yrs. Tissue samples were cultured for 72 hours. In the case of blood samples, the serum was immediately collected. Then ELISA was used for detecting of leptin and IL-6 in supernatant fluids of explant cultures and leptin in serum samples. Statistical analysis was made by Paired T-test and Wilcoxon signed Ranks test.Results: There was no leptin in gingival samples of both cases and control groups. The mean concentration of IL-6 in control and case groups was 81.08±36.72 and 90.35±29.71 pg/ml, respectively. Statistical analysis has shown no difference between case and control groups regarding IL-6 concentration.Conclusion: It is concluded that leptin does not have any role as an inflammatory protein in chronic periodontitis and regarding the absence of leptin in all of gingival samples, we could not consider gingiva as a possible source of leptin.
