Effect of nitrogen on seed yield and content and quality of oil of winter grown sunflower (Helianthus annuus L.)

ABSTRACT     Field trials were carried out at Wad Medani and Sennar locations during season 2008 / 09 to investigate the effects of nitrogen levels on growth, seed yield, oil content and quality of two sunflower cultivars. The treatments consisted of three nitrogen levels (86.7, 108 and 129 kg N/ha, applied as urea) and two cultivars (Damazin and Hysun33). Nitrogen at the higher rate (129 kg N/ha) gave higher seed yield. The oil content ranged from 36.3 to 42.9 %. Nitrogen, cultivar and location had no significant effects on oil content. Oleic and linoleic acids were the most dominant fatty acids in the oil. It is recommended to apply 129 kg N/ha to winter grown sunflower to obtain high seed yield

Histopathologic Pattern of Thyroid Disease in 1351 Thyroidectomy Patients

Abstract Background Thyroid disease poses a major clinical problem. Knowledge of the pattern and distribution of thyroid disease is important to establish prevention and treatment protocols. This is hampered by lack of data. Methods This is a retrospective descriptive study of histopathology reports on thyroid tissue surgically excised from patients over a 10-year-period (from 2009-2020) at a major teaching hospital. Demographic data on patients included the age, gender, geographical location and ethnic origin. Results A total of 1351 histopathological reports on thyroid patients were studied. Twenty one patients (1.6Most of our patients come from Khartoum (76.3Simple multinodular goiter (SMNG) accounted for (78.6Conclusions The study identified the histopathological pattern of thyroid disease. SMNG was the commonest benign disease. Follicular and Hurtle cell carcinoma combined were almost as frequent as papillary carcinoma. Prevention of SMNG by iodinization, early detection of thyroid neoplasms, and studies on goitrogens should be activated
