Anxiety Levels of Children with Primary Ciliary Dyskinesia and Their Mothers at the Beginning of the COVID-19 Pandemic and Change in the First Year

We aimed to assess anxiety of children with primary ciliary dyskinesia (PCD) and their primary caregivers at the beginning of Coronavirus disease-2019 (COVID-19) pandemic and change in levels of anxiety in first year with prolongation of pandemic. This was a two-step study; first step was questionnaire-based, conducted via teleconference. In first step, 29 patients and 105 healthy children and their mothers were participated; 25 children with PCD and their mothers were in second step. Demographic characteristics, clinical informations were recorded. Children’s and mothers’ state and trait anxiety levels were assessed and compared. Anxiety levels of mothers of patients were assessed according to clinical characteristics of children. Mothers’ knowledge of COVID-19 and effect of teleconference on their anxiety was evaluated. State anxiety levels in the first year of pandemic of children with PCD and their mothers were also compared. Compared to control group, state anxiety of children in 13-18 age group and trait anxiety of their mothers were lower (p<0.05). In both groups, trait and state anxiety of 13-18 years old children and mothers positively correlated. Trait anxiety of mothers of patients negatively correlated with patients’ FEV1 and MEF25-75. Patients’ mothers reported feeling less anxiety at the end of teleconference. Anxiety of mothers of patients (especially under 9 years old) had increased as pandemic continued. At the beginning of pandemic, children with PCD were less anxious than healthy children, and their mothers had lower trait anxiety than mothers of healthy children. Being followed for chronic disease and obtaining information about COVID-19 may have reduced anxiety of children with PCD and their mothers. However, as pandemic continues, need to protect their children with PCD from infection, especially of mothers with younger children, may have raised their concerns

Influence maximization in social networks under Deterministic Linear Threshold Model

Due to copyright restrictions, the access to the full text of this article is only available via subscription.We define the new Targeted and Budgeted Influence Maximization under Deterministic Linear Threshold Model problem and develop the novel and scalable TArgeted and BUdgeted Potential Greedy (TABU-PG) algorithm which allows for optional methods to solve this problem. It is an iterative and greedy algorithm that relies on investing in potential future gains when choosing seed nodes. We suggest new real-world mimicking techniques for generating influence weights, thresholds, profits, and costs. Extensive computational experiments on four real network (Epinions, Academia, Pokec and Inploid) show that our proposed heuristics perform significantly better than benchmarks. We equip TABU-PG with novel scalability methods which reduce runtime by limiting the seed node candidate pool, or by selecting more nodes at once, trading-off with spread performance.TÜBİTA

Bu çalışmanın amacı; kışlık kolzaya farklı zamanlarda ve değişik dozlarda humik asit uygulamalarının verim ve verim öğelerine etkilerini belirlemektir. Ankara koşullarında 2013-2014 yılında Tesadüf Bloklarında Bölünmüş Parseller deneme desenine göre üç tekerrürlü olarak kurulan denemede Bristol çeşidi kullanılmıştır. Humik asit dozları olarak (0, 250, 500, 1000 ml/da) 4 farklı doz uygulanmıştır. Humik asit uygulama zamanları olarak; çıkış, 6-8 yapraklı, sapa kalkma, çiçeklenme dönemleri belirlenmiştir. Araştırmada; bitki boyu, ana sapa bağlı yan dal sayısı, ana saptaki kapsül sayısı, kapsülde tohum sayısı, bin tohum ağırlığı ve tohum verimine ait ölçüm ve gözlemler yapılmıştır. Araştırmanın sonucunda ele alınan özelliklerin tamamında humik asit uygulama zamanları ve dozları arasındaki farklılıklar istatistiki açıdan önemli bulunmuştur. En yüksek değerler, bitki boyunda 118.60 cm ile 6-8 yapraklı dönemde ve 250 ml/da humik asit uygulamasından, ana saptaki kapsül sayısı 30.77 adet ile sapa kalkma ve 500 ml/da humik asit dozundan, bin tohum ağırlığı 3.68 g ile 6-8 yapraklı dönemde ile kontrol uygulamasından ve tohum verimi değeri de 238.40 kg/da ile 6-8 yapraklı dönemde ve 250 ml/da uygulamalarından elde edilmiştir. Bu çalışmada genel olarak, humik asit dozlarından 250 ve 500 ml/da uygulamalarının ve uygulama zamanı olarak da 6-8 yapraklı ve sapa kalkma dönemlerinin incelenen özellikler bakımından daha iyi sonuçlar verdiği gözlenmiştirThe purpose of this study was to evaluate effects of durations of different doses of humic acids on yield and yield components of winter rapeseed. The study was carried out at Ankara, the experiment was established as split block design with three replications during 2013-2014. Cv. Bristol was used in the experiment. Humic acid doses of 0, 250, 500, 1000 ml/da were applied. Humic acid was applied at 6-8 leaves stage, bolting and flowering stages. In the study; plant height, number of branches on main stem, number of capsules per main stem, number of seeds per capsule, one thousand seed weight and seed yield were the parameters for which observations were taken. In all of the parameters, discussed in the results of the study statistically significant differences were noted between humic acid application stages and dose. The maximum plant height of 118.60 cm was noted at humic acid application at 6-8 leaf stage using 250 ml/da. The maximum number of 30.77 capsules were noted on main stem at when humic acid was applied at bolting stage using 500 ml/da humic acid. Thousand seed weight of 3.68 g was noted at 6-8 leaf stage on control treatment. Maximum seed yield (238.40 kg/da was noted at 250 ml/da humic acid application at 6-8 leaf stage. Generally, humic acid doses of 250 and 500 ml/da were more productive on all traits after their application at 6-8 leaves stage and bolting stage that resulted in better yields

Factors affecting agricultural characteristics of camelina sativa (L.) crantz under dry-summer subtropical and warm temperate climates

Camelina sativa is one of the alternative plants that can be used to meet exponential growing vegetable oil deficit in Turkey. The purpose of this study was to establish factors affecting crop yield and yield components of the C. sativa using eight genotypes at Ankara (Csa type of climate) and Haymana location (Csb type of climate), Turkey which were separated by a distance of 110 km during 2014. The results of the study showed a significant interaction between C. sativa genotypes and locations for all studied variables. The maximum length of plants was established as 60.95 cm using the line Number 402; the maximum seed yield was determined as 1549.0 kg·ha-1 using the CS-CR1670 population; and the maximum crude oil percentage was established as 51.25% using the CR- 476/65 population at Ankara location. Whereas, at the Haymana location, the maximum plant height of 56.57 cm was noted using the CS-CR1676 population; the maximum seed yield was determined as 1481.0 kg·ha-1 using the CS-163-2073-72 population; and the maximum crude oil percentage was established as 51.42% using the CS-163-2073-72 population in terms of plant height, seed yield and crude oil percentage: CR-476/65, CS-163-2073-72, CS-CR1670 and CSCR1676, Giessen No.3 and NE2006-1 were the best genotypes. Comparing the two locations, maximum seed yield was noted at Ankara location. It was concluded that both locations with Csa and Csb types of climates were appropriate climates for the cultivation of C. sativa under Anatolian conditions. © 2018, Universidad del Zulia. All rights reserved.Camelina está incrementando su popularidad como una planta de materia prima de biocombustibles, debido a las altas grasas insaturadas y poliinsaturadas (54,3%) y al contenido de aceite (28-40%) (Moser y Vaughn, 2010) y a su temporada de desarrollo que es muy corta (Moser y Vaughn, 2010; Obour et al., 2015). Es un cultivo que se propaga en tierras marginales. Es bien sabido que el porcentaje de los ácidos grasos insaturados del aceite de C. sativa (como el oleico, el linoleico, entre otros) es el más alto en comparación con el porcentaje de los ácidos grasos insaturados comunes a otros aceites vegetales (Kurt y Seyis, 2008); por lo tanto, C. sativa es excelente opcion para la produccion de aceite de cocina de calidad y una buena materia prima de biodiesel

Kışlık kolza çeşidi olarak Capitol kullanılmış olup, 5 farklı ekim zamanında(2 Eylül, 16 Eylül, 30 Eylül, 14 Ekim, 28 Ekim) ekimler yapılmıştır. Araştırmada; bitki boyu, ana sapa bağlıyan dal sayısı, ana saptaki kapsül sayısı, kapsülde tohum sayısı, bin tane ağırlığı, tohum verimi, yağ oranıve yağ verimine ait gözlemler yapılmıştır. Araştırma sonucunda ele alınan özelliklerin tamamında ekimzamanları arasındaki farklılıklar istatistiki açıdan önemli bulunmuştur. Ortalama değerlere bakıldığında; enyüksek bitki boyu (158.2 cm), en fazla yan dal sayısı (6.73), en fazla ana saptaki kapsül sayısı (47.53),kapsülde tohum sayısı (29.03), bin tane ağırlığı (2.85 g), tohum verimi (246.70 kg da-1) ile en yüksek yağoranı (% 45.0) ve en yüksek yağ verimi (107.20 kg da-1) de en erken ekimden (2 Eylül) elde edilmiştir. Gecikenekimler tohumdaki yağ oranının azalmasına neden olmuştur. Araştırma sonucunda; Ankara koşullarında kışlıkkolza için en uygun ekim zamanının eylül ayı başı olması gerektiği belirlenmiştirThis research was conducted to find out the effects of different sowing time on yield and yield componentsfor winter rape during growing seasons of 2012 and 2013 (September 2012 - June 2013). The experimentwas designed in randomized complete block design with 3 replications and carried out in the experimentalplots of Field Crops Department of Agricultural Faculty of Ankara University. Winter rape variety Capitol wassown in five different sowing time (September 2, September 16, September 30, October 14 and October 28).Observations and measurements for plant height, lateral stem number, capsule number on main stem, seednumber per capsule, thousand seed weight, seed yield, oil ratio and oil yield were made. According to theresults of the study; the differences were statistically important for all characters in the experiment. The longestplant stem height (158.2 cm), the highest lateral branch number (6.73), capsule number in main stem (47.53),number of seed per capsule (29.03), thousand seed weight (2.85 g), seed yield (246.70 kg da-1) weredetermined in at the earliest sowing time. The highest oil ratio (45.0 %) and oil yield (107.20 kg da-1) weresimilarly obtained in the earliest sowing date (September 2). Delayed sowing resulted in decreasing of oilratio. The best sowing time for winter rapeseed was at the beginning of September under Ankara condition

Determining the age group-based cut-off values of serum anti-Mullerian hormone concentrations to diagnose polycystic ovary syndrome

Objective: To determine the cut-off values of the serum anti-Müllerian hormone (AMH) concentration for different age groups (21–25, 26–30, 31–35 years) to diagnose polycystic ovary syndrome (PCOS). Methods: In total, 187 women aged 21–35 years were included in this descriptive study. Patients diagnosed with PCOS according to the Rotterdam Criteria formed the PCOS group (n = 93), whereas those without symptoms related to PCOS formed the control group (n = 94). Follicular phase serum hormone concentrations were evaluated during the endocrinological assessment of patients with PCOS. Serum levels of estradiol, follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin, total testosterone, dehydroepiandrosterone sulfate, sex hormone-binding globulin, androstenedione, and AMH were measured. The free androgen index and LH/FSH ratio were calculated. Cut-off values of serum AMH concentrations for the age groups were measured using receiver operating characteristic curve analysis. Results: The prevalence rates of frank, ovulatory, normoandrogenic, and non-polycystic ovary PCOS were 69.9, 10.8, 10.8, and 8.6%, respectively. Serum AMH concentrations >5.56 ng/mL were associated with PCOS in the 21–25-year-old group. The cut-off value was 4.01 ng/mL in the 26–30-year-old group, whereas it was 3.42 ng/mL in the oldest age group. The correlation between the antral follicle count (AFC) and serum AMH level was strong for each age group. Conclusions: The serum AMH concentration is a valuable parameter for assessing patients with symptoms indicative of PCOS. We recommend measuring serum AMH levels to support the diagnosis or to use them instead of the AFC for the Rotterdam criteria
