Comparison of Drought Tolerance of Some Wheat Varieties Grown in Turkey

The effect of drought stress on 21 wheat (Triticum aestivum L.) varieties were screened at the germination stage for drought tolerance. Four levels of osmotic stress was assessed by applying different polyethylene glycol (PEG-6000%253B 0%25, 10%25, 15%25 and 20%25 (w%252Fv)) concentrations. Germination rate, root-shoot length, total chlorophyll amount (SPAD), specific leaf area (SLA), relative water content (RWC), superoxide anion (O2.ˉ) and hydrogen peroxide (H2O2) accumulation were determined on the 8th day after sowing. The increased osmotic stress, significantly reduced germination rate, root-shoot length, SLA, chlorophyll amount and RWC in KateA-1, Gelibolu and Sultan-95 varieties. Pehlivan, Karahan-99 and Tekirdağ varieties were less affected by osmotic stress and these varieties were determined as drought tolerant varieties than other varieties

Reliability and Validity of Attentional Style Questionnaire: Turkish Form

Attention is an important part of cognitive and perceptual processes. Attention includes both external processes related to the environment and internal processes such as heredity. In addition, measuring attention processes, which have two dimensions, top-down and bottom-up, is important in terms of both learning processes and determining some psychopathologies. Based on this, it was aimed to adapt the Attention Style Questionnaire (ASQ) into Turkish in this study. The study group includes of 372 university students. Data collection materials included personal information form, Attention Styles Questionnaire and Control Dimension of Self-regulation Scale. Language validity and criterion-related validity analysis were performed for validity studies. Confirmatory factor analysis and test-retest analysis were utilized for reliability studies. The two-factor structure in the original structure of the scale was confirmed through confirmatory factor analysis results. Furthermore, the ASQ was found to be highly correlated with the Control Dimension of Self-regulation Scale. According to the findings obtained for reliability, Cronbach's alpha coefficients were found as .81 for the cognitive avoidance sub-dimension and .70 for the focusing sub-dimension. Test-retest correlation coefficients were determined as .76 for the cognitive avoidance sub-dimension and .75 for the focusing sub-dimension. Research results indicate that Attention Style Questionnaire is a reliable and valid measurement tool in determining the style of the attention to university students in Türkiye

Calprotectin levels in patients with rheumatoid arthritis to assess and association with exercise treatment

Rheumatoid arthritis (RA) is a chronic, inflammatory, and autoimmune disease that can cause permanent joint damage. In our study, we aim to analyze the change in calprotectin levels following the low-density exercise levels applied to the patients with RA. Twenty-eight patients with RA and 30 healthy controls were included in this study. To evaluate the activity of disease in RA, scores of disease activity that has increased (DAS-28) are figured. Calprotectin, nitric oxide (NO), white blood cell (WBC) count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and rheumatoid factor (RF) levels are tested as the laboratory evaluation. Calprotectin, NO, CRP, ESR, WBC, and RF levels were significantly higher in the patient group compared to the control group (p < 0.01, p < 0.001, p < 0.01, p < 0.01, p < 0.01, and p < 0.05, respectively). In correlation analysis applied to the patient group with RA, there has been determined a positive relation with calprotectin, and DAS-28, CRP, NO, RF, and WBC (p < 0.001, p < 0.05, p < 0.001, p < 0.05, and p < 0.05, respectively). In result of the low-density exercise treatment applied to patients with RA for 8 weeks, there has been determined a significant decrease in calprotectin, DAS-28, NO, CRP, ESR, and RF levels (p < 0.05, p < 0.001, p < 0.01, p < 0.05, p < 0.05, and p < 0.05, respectively). As a result, a significant relation is found between RA disease activity and calprotectin levels and other inflammatory parameters. At the same time, it shows that calprotectin which is a significant indicator of local inflammation can be used as a good identifier in following up exercise treatment

Contribution of spiral artery blood flow changes assessed by transvaginal color Doppler sonography for predicting endometrial pathologies

ive: To investigate the diagnostic value of blood flow measurements in spiral artery by transvaginal color Doppler sonography (CDS) in predicting endometrial pathologies.Methods: Ninety-seven patients presenting with abnormal uterine bleeding and requiring endometrial assessment were included in this prospective observational study. Endometrial thickness, structure and echogenicity were recorded. Pulsatility index (PI) and resistive index (RI) of the spiral artery were measured by transvaginal CDS. Endometrial sampling was performed for all subjects. Sonographic and hystopathologic findings were compared.Results: The histopathological diagnoses were as follows; 39 cases (40.2%) endometrial polyp, 9 cases (9.3%) endometrial hyperplasia, 10 cases (10.3) submucous myoma, 7 cases (7.2%) endometrium cancer, and 32 cases (33%) nonspecific findings. The spiral artery PI in endometrium cancer group was highly significantly lower than other groups (p<0.01). The spiral artery RI was also significantly lower in the patients with malignant histology (p<0.05). Conclusion: Endometrial pathologies are associated significantly with endometrial spiral artery Doppler changes.Key words: Spiral artery, Doppler ultrasonography, endometriu

Evaluation of dietary quality of adolescents using Healthy Eating Index

The aim of this study was to use the Healthy Eating Index-2005 (HEI-2005) to assess diet quality and determine the relationship between the HEI-2005 and the energy and nutrient intakes of adolescents. A cross-sectional study was conducted on 1,104 healthy adolescents, mean age of 15.8 ± 1.24 years. Dietary intake was measured with the 24-hour dietary recall method, and dietary quality was assessed by means of the HEI-2005. Diet quality scores ranged from 23.7 to 77.5. The mean score was found to be 51.5 ± 9.07 according to the HEI-2005. There were no differences according to gender; 42.8% had a poor diet and 57.2% had a diet that needs improvement. No subjects had a "good diet". Lower mean subgroup scores were found for whole grains, total vegetables, total fruits, dairy products, and meat and beans. Fruits and vegetables scores were significantly high in girls, whereas sodium, oil, and meat and beans scores were significantly high in boys. Total HEI-2005 scores were increasingly associated with parental education level when age and gender were adjusted. There was a negative correlation between HEI-2005 scores and age, total energy intake, and fat intake. Positive correlation was only observed in the HEI-2005 scores for protein and dietary fibre intakes. Consequently, the overall diet quality and nutritional habits of Turkish adolescents need modification and improvement. In the family, measures should be initiated by the government, including advertisements and campaigns
