background: analysis of many proteins produced during the transition into the stationary phase and under stress conditions (including starvation stress) demonstrated that a number of novel proteins were induced in common to each stress and could be the reason for cross-protection in bacterial cells. it is necessary to investigate the synthesis of these proteins during different stress condition...

Effects of mowing and grazing on a Leymus chinensis grassland in the Songnen plain of northeastern China were studied using eight replicates of four grazing and mowing treatments. Canopy cover and biomass of the dominant species (L. chinensis) were lower, and cover of the halophyte Suaeda corniculata higher, on grazed than ungrazed; ungrazed plots showed a response to mowing, but not grazing; s...

The antioxidant activity and phytoconstituents of the hydromethanolic extract of Litchi chinensis (HELC) fruit was explored in the present study. The antioxidant potential of extract has been evaluated using several antioxidant models and results were compared to standards. Fruit extract showed effective reducing power and free radical scavenging activity in a dose-dependent manner. In case o...

Effects of different dietary supplements of plant carotenoid sources on growth, coloration and behavioural activities of Trichogaster fasciata were carried out. Three groups of fish were fed with petal powder of rose (Rosa chinensis), China rose (Hibiscus rosasinensis) and marigold (Tagetes erecta) separately as carotenoid source along with the same basic ingredients for 90 days. The mean final...

Cis chinensis Lawrence (Coleoptera: Ciidae) is recorded for the first time from Brazil. The species has been previously recognized as pest of commercial dried fungi in China, Thailand and USA. The status of the species is discussed, and the Cis multidentatus species-group is delimited to encompass C. chinensis and the morphologically similar species C. aldabranus Scott, C. mikagensis Nobuchi & ...

Problem statement: In the current scenario, photo-aging is a major problem causing skin wrinkling and hyperpigmentation. Therefore, elastase and tyrosinase inhibitors play an important role in the treatment of skin aging and thus, gaining a special attention in cosmetic industries. Approach: In the screening of Korean medicinal plants to search the potent elastase and tyrosinase inhibitors, the...

The effect of colony size and age on growth and sexual reproduction was examined by taking small-sized fragments from large mature donor colonies of Goniastrea aspera and Favites chinensis. Both species are massive colonial corals in the family Faviidae. Monopolyp and oligopolyp (5 to 8 polyps) fragments were established. The fragments were cultured in running seawater aquaria for 22 mo, and gr...

The genus Rosa L. (Rosaceae) was recently treated floristically for North America, but range extensions and an additional taxon have been confirmed since then and are detailed here. These new reports document range extensions in the US and Canada of some native and introduced Rosa species, and new distributions and population data for several established Rosa hybrids (nothospecies). Some introd...

The Jaramillo Event was originally defined by Doell and Dalrymple in 1966 on the basis of K^Ar ages from sanidine in the normally, transitionally and reversely magnetized rhyolite domes named Cerro del Abrigo, Cerro Santa Rosa I and Cerro Santa Rosa II, respectively, that erupted following collapse of the archetypal Valles Caldera, New Mexico. We have collected new paleomagnetic data from the t...
