This study shows that the fruit fly, Ceratitis rosa (Karsch), has a significantly longer life span than the medfly, C. capitata (Wiedemann); the species used as a model organism for the demographics of insect aging. This was somewhat surprising given that both have similar distributions and overlapping niches. We postulate that the greater longevity of C. rosa is related to the fact that it can...

Five known lignans, (+)-pinoresinol (1), (+)-8-hydroxypinoresinol (2), (-)-dehydrodiconiferyl alcohol (3), (+)-trans-dehydrodiconiferyl alcohol (4), and (-)-olivil (5), were isolated from the roots of Rosa multiflora for the first time. Their structures were determined using spectroscopic data.

We introduce a natural Hopf algebra structure on the space of noncommutative symmetric functions which was recently studied as a vector space by Rosas and Sagan [12]. The bases for this algebra are indexed by set partitions. We show that there exist a natural inclusion of the Hopf algebra of noncommutative symmetric functions studied in [17] in this larger space. We also consider this algebra a...

Earthworms were collected in forests, damp habitats, springs, orchards and agricultural fields of the Kohgiluyeh & Boyer Ahmad Province, Iran, from April 2009 to April 2010. Specimens were collected at 20 established stations by digging and by diluted formalin methods. Ten species belonging to family Lumbricidae were identified based on morphology: Aporrectodea caliginosa (Savigny, 1826), Ap. r...

The world we live in is a biosphere influenced by all organisms who inhabit it. It is also an ecology of genes, with some having rather startling effects. The premise put forth in this issue is cytochrome P450 is a significant player in the world around us. Life and the Earth itself would be visibly different and diminished without cytochrome P450s. The contributions to this issue range from ev...

Pollen quantity, viability and germination of four genotypes of Rosa dumalis and R. villosa were investigated. The number of anthers per flower were 90.3 in genotype 4 (Rosa villosa) and 116.4 in genotype 1 (Rosa dumalis). Genotype 1 showed the highest pollen viability on the basis of both TTC and IKI tests. Most of the rose species are diploid but there are several species with higher ploidy l...

The effects of dietary Rosa mosqueta (RM, Rosa rubiginosa) oil, rich in α-linolenic acid, in the prevention of liver steatosis were studied in mice fed a high fat diet (HFD). C57BL/6j mice were fed either a control diet or HFD with or without RM oil for 12 weeks. The results indicate that RM oil supplementation decreases fat infiltration of the liver from 43.8% to 6.2%, improving the hepatic ox...
