مقدمه: داروهای سیتوتوکسیک عواملی هستند که به طور مستقیم سلول را نابود می نمایند به طوری که بر مراحل مختلف سنتز و فعالیت اسیدهای نوکلئیک اثر می گذارند و تقسیم سلولی را مهار می کنند. بررسی اثرات سیتوتوکسیک عصاره های خام گیاهی به روش های in vitro هزینه کمتری داشته، حساسیت بیشتری دارا بوده و آزمایش در زمان کوتاه قابل انجام است از طرفی مقدار نمونه موردنیاز برای آزمایش نیز کمتر است. هدف: در این مطال...
Two skeletons of the large compsognathid Sinocalliopteryx gigas include intact abdominal contents. Both specimens come from the Jianshangou Beds of the lower Yixian Formation (Neocomian), Liaoning, China. The holotype of S. gigas preserves a partial dromaeosaurid leg in the abdominal cavity, here attributed to Sinornithosaurus. A second, newly-discovered specimen preserves the remains of at lea...
The larvae of the southern beet webworm Herpetogramma bipunctalis (Fabricius, 1794) damage the leaves of species in the plant genus Rubus. The present study investigated the biology of H. bipunctalis and developed a protocol for raising H. bipunctalis under laboratory conditions. On the basis of the biological data, we devised a life table. In order to develop the rearing procedures, we determi...
To develop new type of sponge cake, the effects of partial (0~40%) replacement with Rubus coreanus powder (RCP) on the quality characteristics of sponge cakes were investigated. The pH level and moisture content ranged from 4.05~8.23 and 28.49~36.59, respectively, and significantly decreased upon addition of RCP (P<0.05). Baking loss rate and cake firmness significantly increased with higher RC...
Young shoots of Rubus species have been used for healing of wounds, infected insect bites and pimples in folk medicine for ages. In order to evaluate the wound healing activity of Rubus sanctus, four different extracts were prepared from the whole aerial parts of the plant by using n-hexane, chloroform, ethyl acetate and methanol, respectively. Incision wound healing model by using tensiometer ...
In the present article, two new mitosporic spccies are introdued, namely: Cercospora fraxinicola Ershad, sp. nov. on Fraxinus rotundifolia and Ramularia rubicola Ershad, sp. nov. on Rubus caesicus.
جنس تمشک، از تیره Rosaceae، حدود 750 گونه در دنیا دارد که هشت گونه و پنج دورگه آن از ایران گزارش شده است. در پژوهش حاضر، صفات تشریحی ساقه، برگچه، دمبرگ، گوشوارک و دمگل در هفت گونه از جنس تمشک Rubus متعلق به زیرجنس Rubus شامل: R .caesius، R. discolor، R. dolichocarpus، R. hirtus، R. hyrcanus، R .persicus و R. sanctus بررسی شد. نمونههای گیاهی جمعآوری شده در محلول تثبیتکننده قرار گرفته، سپس برش...
There are several issues faced by a developer when holistic response-time analysis (HRTA) is implemented and integrated with a tool chain. The developer has to not only implement the analysis, but also extract unambiguous timing and tracing information from design model. We present an implementation of HRTA as a plug-in for an industrial tool suite Rubus-ICE that is used for component-based dev...
Several hydrolytic enzyme activities were detected in the wall of developing cells of Rubus fruticosus in suspension culture. The corresponding substrates of the enzymes are mostly polysaccharide wall constituents, except for chitinase activity. The activities measured when the enzymes were in the free state or wall-bound showed the positive influence of the cell wall micro-environment. Changes...
Rubus imperialis, Artemia salina, 3-O-methylellagic-4'-O-alpha-rhamnose Acid Screening of different extracts, fractions and compounds from Rubus imperialis Chum. Schl. (Rosaceae) has been conduced using the brine shrimp microwell cytotoxicity assay. Three parts of the plant (methanolic extract from leaves, roots and stems), three fractions from roots (hexane, ethyl acetate and butanol) and thre...
