Rabbit Anti-Human CFI Polyclonal Antibody

The results of studies on the frost resistance ofOlea europaeaL. varieties and its subspeciesO. europaeasubsp.cuspidata(Wall. and G. Don) Cif. under the conditions of the Southern Coast of Crimea (SCC), as well as the influence of temperature close to the absolute minimum value (-15 degrees C) on the state of the photosynthetic apparatus, catalase activity, polyphenol oxidase, and the content of proline and phenolic compounds, are shown. It was established that a relatively high frost resistance is characteristic of the Nikitskaya variety under the conditions of the SCC. Varieties Ascoliano, Coregiolo, and Razzo turned out to be slightly frost-resistant. Minimum resistance was detected in the subspeciesO. europaeasubsp.cuspidata. The temperature of -15 degrees C led to irreversible disruptions in the photosynthetic apparatus of weak varieties Razzo, Coregiolo andO. europaeasubsp.cuspidata, which manifested in a significant decrease in photosynthetic activity immediately after the end of low-temperature exposure (by 80.19, 50.0, and 89.78%, respectively) as well as a fluorescence decay coefficient below the vital norm. After 24 h, a slowdown in the decrease in the parameters of chlorophyll fluorescence induction (CFI) was noted in the Ascoliano and Nikitskaya varieties. It was revealed that negative temperatures contribute to a decrease in the activity of catalase in weakly resistantO. europaeagenotypes (by 40-60% on average) in contrast to the frost-resistant variety Nikitskaya, in which the activity of this enzyme remained almost unchanged. The change in polyphenol oxidase activity was multidirectional. In the Razzo and Coregiolo varieties, an increase in polyphenol oxidase activity was noted (19 and 24%, respectively). A decrease (by 8 and 37%, respectively) was noted in the subspeciesO. europaeasubsp.cuspidataand Nikitskaya variety. It was shown that, under the influence of negative temperatures, representatives ofO. europaeadecrease proline concentration in leaf tissues (by 17-55%). The most significant changes were detected in the variety Coregiolo (by 45.09%). The total content of phenolic compounds decreased in all weakly frost-resistant varieties andO. europaeasubsp.cuspidataby 7-42% and remained unchanged in the frost-resistant variety Nikitskaya. It has been established that negative temperatures cause irreversible changes in the photosynthetic apparatus in weakly resistant representatives ofO. europaea. The correlation of the degree of frost resistance of the studied genotypes with the activity of catalase and with the content of proline and phenolic compounds in leaf tissues was revealed.

Background: Body image shame considerably contributes to the development and persistence of eating and body image disorders. Objectives: The current study was done to determine the psychometric properties of the body image shame scale and introduce a suitable measure for researchers and therapists in the field of psychological health. Methods: In this study, 409 (136 men and 273 females) individuals who referred to cosmetic surgery clinics in Tehran were chosen. The construct validity of the body image shame was assessed using confirmatory factor analysis and divergent and convergent validity. To assess the divergent and convergent validity of the body compassion scale, appearance anxiety inventory, dysmorphic concern questionnaire and Forms of Self-Criticizing/Attacking and Self-Reassuring Scale were used. Internal Consistency and test-retest reliability (4 weeks' interval) were used to evaluate reliability. LISREL V8.80 and SSPS V20 were used for data analysis. Results: The results of confirmatory factor analysis showed that the two-factor model (internal and external body image shame) fitted the data (RMSEA = 0.07, NFI = 0.94, CFI = 0.92). Body image shame scale had a positive, significant correlation with dysmorphic concern, appearance anxiety, and self-criticism, and a negative, significant correlation with body compassion (P < 0.05). Also, Cronbach's alpha coefficient, for the whole of scale, internal body image shame, and external body image shame were 0.85, 0.79, and 0.82, respectively. Conclusions: Psychometric properties of the persian version of thebodyimageshamescale wereconfirmedin this study. Therefore, it can be used as a valid instrument in research and clinical works in populations with concerns about body image.
