The primary spermatocytes of Drosophila virilis have been shown to undergo an approximate 300-fold increase in volume and to possess an abundance of ribo somes in the cytoplasm (Ito 1960). These ribosomes are probably involved in the biosynthesis of the various materials needed for this tremendous volumetric increase. Olivieri and Olivieri (1965) have demonstrated that RNA synthesis occurs in s...
Transfusion therapy for inherited anemias and acquired refractory anemias both improves the quality of life and prolongs survival. A consequence of chronic transfusion therapy is secondary iron overload, which adversely affects the function of the heart, the liver and other organs. This session will review the use of iron chelating agents in the management of transfusion-induced secondary iron ...
به منظور بررسی ارتباط پوشش گیاهی با برخی عوامل اکولوژیک در منطقه فریدونشهر اصفهان و شناسایی مهم ترین عوامل موثر بر رشد و استقرار گیاهان، اقدام به استقرار یک ترانسکست در امتداد گرادیان شمال غربی- جنوب شرقی به طول تقریبی 100 کیلومتر گردید. در طول این ترانسکت با توجه خصوصیات پوشش گیاهی و توپوگرافی پنج مکان به عنوان مکان های مورد مطالعه انتخاب شدند. عوامل اقلیم (8عامل)، خاک (8عامل)، فیزیوگرافی (2عا...
We isolated 8 novel 28-noroleanane-derived spirocyclic triterpenoids with unusual skeleton structures, phlomisone (1), phlomistetraol A (2), phlomistetraol B (3), phlomistetraol C (4), phlomispentaol (5), phlomishexaol A (6), phlomishexaol B (7), and phlomisin (8), from the ethanol extract of Phlomis umbrosa rhizomes. Their structures were elucidated on the basis of spectroscopic methods, inclu...
تحقیق حاضر عدد کروموزومی هفت گونه متعلق به پنج خانواده از ایران را گزارش میکند. شمارش کروموزومی برای چهار گونه شامل: Tanacetum dumosum (2n=18), Phlomis elliptica (2n=20), Alcea aucheri (2n=42) و2n=20)) Phlomis aucheri برای اولین بار گزارش میشود. همچنین سطح تتراپلوییدی (2n=4x=32) برای گونه Fibigia umbellata نیز برای نخستین بار ارایه شده است. پارامترهای کروموزومی آنها بررسی شد و ایدیوگرا...
It has been recently shown that polysaccharides isolated from plants exhibit a number of beneficial therapeutic properties. Bauhinia championii (Benth.) Benth. has been widely used for the clinical treatment of knee osteoarthritis (OA) in China. However, the underlying molecular mechanisms of knee OA treatment have yet to be elucidated. In the present study, we investigated the effects of Bauhi...
A combined approach of subwindow factor analysis and spectral correlative chromatography was used to analyze the volatile components in Radix Flemingiae Macrophyllae and Flemingiae Latifolia Benth, one of its substitutes. After extraction by a water distillation method, the volatile components in Radix Flemingiae Macrophyllae and Flemingiae Latifolia Benth were detected by GC-MS. Then the quali...
Traditionally Thymus linearis Benth. have been used for treatment of various diseases including hypertension. The present study was conducted to evaluate the hypotensive and antihypertensive effect of aqueous methanolic extract of aerial parts of Thymus linearis Benth. in normotensive and hypertensive rats. Acute and subchronic studies were also conducted. The aqueous methanolic extract produce...
