Pollen morphology of Ebenus L., (Leguminosae : subfamily Papilionoideae) in Turkey

Pollen grams of 12 species and 3 varieties of the genus Ebenus L., Leguminosae subfamily papilionoideae have been examined using light microscopy (LM) and scanning electron microscopy (SEM). Pollen description of each taxon has been given Pollen grains of Ebenus L. species examined are radially symmetrical, isopolar, tricolpate, prolate rarely perprolate. Their ornamentations are reticulate. The exine structure are similar, ektexine thicker than endexine. The pollen morphology seems to be very similar to each other

Morphological, anatomical, palynological, karyological and autecological characters of Centaurea amaena Boiss. & Balansa [Sect. Phalolepis (Centaurea/Asteraceae)]

Centaurea amaena Boiss. & Balansa included in the Phalolepis section of the Compositae (Asteraceae) family is an endemic species that is under critical risk of extinction. The morphological, anatomical, palynological, karyological and autecological features have been studied in this study. In accordance with the new observations, additional information was added to the previous description of the species, and the description was edited. Moreover, threat category of C. amaena has been updated according to International Union for Conservation of Nature criterions as CR B2ab(i,iii) (previously EN). Pollen grains are symmetric and isopolar, tricolporate. The somatic chromosome number is determined as 2n = 18 in C. amaena. The karyotype formula of this species consists of three median chromosome pairs and six submedian chromosome pairs. The physical and chemical properties of the soil in which the plant grows are, sandy-loam, weak acid, high organic matter

Association between Polycystic Ovary Syndrome, Oral Microbiota and Systemic Antibody Responses

WOS: 000342921200079PubMed ID: 25232962Polycystic ovary syndrome (PCOS) is a hormonal disorder of women that not only is the leading cause of infertility but also shows a reciprocal link with oral health. This study aimed to investigate the hypothesis that the levels of putative periodontal pathogens in saliva and their antibody response in serum are elevated in PCOS, compared to systemic health. A total of 125 women were included in four groups; 45 women with PCOS and healthy periodontium, 35 women with PCOS and gingivitis, 25 systemically and periodontally healthy women, 20 systemically healthy women with gingivitis. Salivary levels of seven putative periodontal pathogens were analyzed by quantitative real-time polymerase chain reaction and serum antibody levels were analyzed by ELISA. In women with PCOS, salivary Porphyromonas gingivalis, Fusobacterium nucleatum, Streptococcus oralis and Tannerella forsythia levels were higher than matched systemically healthy women, particularly in the case of gingivitis. Aggregatibacter actinomycetemcomitans and Treponema denticola levels were similar among study groups. The presence of PCOS also enhanced P. gingivalis, Prevotella intermedia and S. oralis serum antibody levels, when gingivitis was also present. Gingival inflammation correlated positively with levels of the studied taxa in saliva, particularly in PCOS. The presence of P. gingivalis and F. nucleatum in saliva also exhibited a strong positive correlation with the corresponding serum antibody levels. In conclusion, as an underlying systemic endocrine condition, PCOS may quantitatively affect the composition of oral microbiota and the raised systemic response to selective members of this microbial community, exerting a confounding role in resultant gingival inflammation and periodontal health. The most consistent effect appeared to be exerted on P. gingivalis.Continental European Division of the International Association of Dental Research; Institute of Oral Biology, Center of Dental Medicine, University of ZurichThis study was supported by a Visiting Research Fellowship (AA) of the Continental European Division of the International Association of Dental Research, and the Institute of Oral Biology, Center of Dental Medicine, University of Zurich.

Turkish version of the Yale Food Addiction Scale

Background Yale Food Addiction Scale (YFAS) was established to identify individuals exhibiting signs of addiction towards certain types of food. This study aimed to develop a Turkish version of the Yale Food Addiction Scale and test its psychometric properties. Methods The backward translation techniques were used to develop Turkish versions of the YFAS, and its reproducibility was assessed. Turkish version of the YFAS was administered to a total of 1033 participants (439 men and 594 women), aged 19–65 years. Exploratory factor analysis and confirmatory factor analysis were used to examine the factorial structure of the tool. Construct validity was assessed by principal component factor analysis with varimax rotation. Reliabilities were estimated with Cronbach’s alpha coefficient. The criterion-related validity was tested by the administration of Eating Attitude Test-26 (EAT-26) to all participants. Results The primary factor loadings for seven items were ranged between 0.45 and 0.79, and no items cross-loaded onto other factors. The fit indices showed that eight items of the YFAS were a good representation of the item responses and each item loaded significantly on the specified factor (p < 0.001 for each). YFAS subscales had a high internal consistency and test–retest reliability. The criterion-related validity of the tool showed a positive relationship with scales of the EAT-26. Conclusion Current study suggested that the Turkish version of the YFAS is a reliable, valid, and useful tool for assessing the signs of food addiction in a non-clinical sample.PubMedWoSScopu
