Background: Iron deficiency is the most common nutritional deficit in the world. More than 50% of anemia in pregnancy results from iron deficiency and it is suggested that it may be associated with negative pregnancy outcomes. Aim: The aim of this study was to evaluate the incidence of irony deficiency anemia in pregnancy in the East Marmara region of Turkey in order to determine its prevalence in the country along with the effects and associations of iron supplementation or iron status on maternal and neonatal outcomes. Study Design: The study was designed as a prospective, longitudinal qualitative study. Method: This study was conducted in six centers in three provinces of the East Marmara region(Turkey) and included a total of 1102 pregnant women. Blood samples were collected for hematological status and serum ferritin levels during pregnancy, and the adverse maternal and perinatal outcomes were determined. Results: The rate of anemia among the women included in the study was 19.8%, with 44% of them receiving iron supplementation. The maternal age was lower in the anemic group(26.5 vs. 27.7, p = 0.01). Selective iron use was more frequent in the anemic group, while routine iron use was more frequent in the non-anemic group(47.1% vs. 29.3%; p = 0.01). Conclusions: Iron deficiency anemia is a frequent problem in pregnancy. However, many anemic pregnant women do not receive iron therapy. Iron supplementation may have positive effects on some maternal and perinatal outcomes. In order to combat iron deficiency anemia in pregnancy, widespread use of iron supplements should be established.

This study was carried out to determine some yield characteristics of Hungarian vetch varieties and to evaluate them as bee pastures based on bee-plant relationship. Eight Hungarian vetch varieties were used in the study. In Bingöl province, where the research was carried out, flowering of Hungarian vetch started on April 18. Counts started on April 23 and ended on May 11. Hungarian vetch remained blooming for about three weeks in Bingöl province. An average of 14.9 bees per m2 visited the Hungarian vetch and the bees remained on the flower for an average of 9.0 seconds. It has been determined that Hungarian vetch has an average of 377 flowers per m2, the natural plant height is 38.7 cm, the fruit per plant is 21.3, the seed per fruit is 4.0, the seed yield is 22.5 kg/da, and the thousand-seed weight is 33.0 g. Also, it was observed that the Hungarian vetch reached the highest natural plant height by April 30, the number of bees visiting the plant was high on May 04-07, the bees stayed on flower for a long time when the plant bloomed the most. It was seen that Kansur and Efes varieties are distinguishable for the features such as the number of bees per m2, the duration of the bee staying on flower, and the number of flowers, while the features such as natural plant height, seed yield and thousand-seed weight, are distinguished in Akçalar, Efes and Tarm Beyazı varieties.

(Düzce Üniversitesi, 2010) Tütüncü, Yasemin Ateş; Berker, Dilek; Işık, Serhat; Özoğuz, Ufuk; Güler, Serdar; Aydın, Yusuf
Introduction: Preoperative treatment options in thyrotoxic patients are antithyroid drugs,potassium iodide, beta blockers and corticosteroids. Sometimes these treatment regimens havenot been so successful for the patients to make them ready for the operation. So we thought thatplasmapheresis (PP) could be an alternative to these treatments. Methods: Two thyrotoxic patients with Graves’ disease and one patient with toxic multinodulargoiter were included in the study. All patients were candidates to surgical operation due to thecontraindication of other medical treatment choices. On admission, all patients had severeuncontrolled hyperthyroidism. In order to prepare our patients to operation, all the patients weregiven beta blockers and inorganic potassium iodide and corticosteroid at first but disease controlcould not be achieved in terms of thyrotoxicosis. So PP was performed at an average of 3 to 5sessions. Results: After PP, all patients’ thyroid hormone concentrations were significantly reduced. Onepatient had an anaphylactic reaction during 3th session of PP. Total thyroidectomy wasperformed to all patients without any complications.Conclusions: We concluded that PP could be used as an alternative therapeutic option in thepreoperative management of severe thyrotoxic patients
Effect of vanillic acid against oxidative stress induced by glyphosate in Saccharomyces cerevisiae
(Ersin YÜCEL, 2019) Özcan, Gözde; Demir, Ersin; Yılmaz, Prof. Dr. Ökkeş; Erişir, Figen Erdem; Zengin, Hatayi
Glyphosate is a widely used broad-spectrum herbicide. Vanilic acid is a phenolic acid found naturally in many plants. In this study, the effect of vanilic acid against oxidative stress induced by glyphosate in Saccharomyces cerevisiae was investigated. S. cerevisiae was proliferated and developed in YEDP medium. Both glyphosate and vanilic acid were added to the development environment of Saccharomyces cerevisiae to be 200, 400 and 800 mg per liter. At the end of the experiment, Saccharomyces cerevisiae samples (Reduced glutathione (GSH), oxidized glutathione (GSSG), Malondialhedit (MDA), fatty acid, E, D, K vitamins and phytosterol) were analyzed in HPLC and GC devices. Antioxidant potential of vanillic acid was also identified. In this study, the effect of vanillic acid against oxidative stress and toxicity caused by glyphosate in S. cerevisiae was investigated for the first time. In S. cerevisiae administered glyphosate, there were statistically significant changes in MDA, GSH, GSSG, protein, fatty acid, E, D, K vitamins and phytosterol levels, but the vanilic acid applied was detected statistically significantly reduced the changes in these parameters. As a result of analysis by gas chromatography, the yeast cell of octanoic acid (8: 0), lauric acid (12: 0), myristic acid (14: 0), palmitic acid (16: 0), palmitoleic acid (16:1 n-7), stearic acid (18: 0), oleic acid (18:1 n-9) and linoleic acid (18:2 n-6) acids were observed. Vitamin D, E and K were analyzed with HPLC device. As a result of this analysis, molecules such as K2, ?-tocopherol, D2, D3, ?-tocopherol, ergosterol, K1, stigmasterol, ß-sitosterol were identified. Biochemical analysis showed that cell density in culture medium containing 800 mg per liter of glyphosate decreased. It was found that vanilic acid showed beneficial effects against oxidative stress caused by glyphosate in Saccharomyces cerevisiae.
Hemşirelik Öğrencilerinin Psikolojik Yardım Almaya Yönelik Tutumları: Kendini Damgalama ve Sosyal Damgalanmanın Rolü
(Aydın Adnan Menderes Üniversitesi, 2019) Daştan, Nihal Bostancı; Kaya, Fadime; Şık, Tuğçe
Giriş: Bu araştırmanın amacı, sosyal damgalanma ve kendini damgalamanın hemşirelik öğrencilerinin psikolojik yardım almaya yönelik tutumlarına etkisini incelemektir. Yöntem: Katılımcıları 2015-2016 eğitim öğretim yılında Kafkas Üniversitesi Sağlık Bilimleri Fakültesi’nin hemşirelik programındaki 398 öğrenci oluşturmuştur. Veriler Profesyonel Psikolojik Yardım Arama Tutum Ölçeği (PPYATÖ), Psikolojik Yardım Alma Nedeniyle Kendini Damgalama Ölçeği ve Psikolojik Yardım Alma Nedeniyle Sosyal Damgalanma Ölçeği ile toplanmıştır. Verilerin istatistiksel analizinde bağımsız gruplarda t testi, tek yönlü varyans analizi (ANOVA), pearson korelasyon analizi kullanılmıştır. Bulgular: Cinsiyet, kendinin ve aileden birinin psikolojik yardım alma öyküsü ile PPYATÖ Zorlanma, Danışmaya Olan İnanç, İhtiyaç Hissetme ve Sosyal Kabul alt-ölçek puanları arasında anlamlı ilişki bulunmuştur. Kendini Damgalama (KD) ve Sosyal Damgalanma (SD) Ölçekleri ile Kişilerarası Açıklık (KD: r=.299; p < 0.001; SD: r=.252; p < 0.001), İhtiyaç Hissetme (KD: r=.128; p < 0.05; SD: r=.229; p < 0.001) ve Sosyal Kabul (KD: r=.479; p < 0.001; SD: r=.187; p < 0.01) alt boyutları arasında pozitif yönde korelasyon; Zorlanma (r=.-430; p < 0.001) ve Danışmaya Olan İnanç (r=.-348; p < 0.001) alt boyutları ile sadece Kendini Damgalama (KD) arasında ise negatif yönde korelasyon belirlenmiştir. Sonuç: Hem kendini damgalama hem de sosyal damgalama, profesyonel psikolojik yardım arama tutumunu olumsuz yönde etkilemektedir.
