The objective of this study was to obtain a quantitative assessment of the monophyly of morning glory taxa, specifically the genus Ipomoea and the tribe Argyreieae. Previous systematic studies of morning glories intimated the paraphyly of Ipomoea by suggesting that the genera within the tribe Argyreieae are derived from within Ipomoea; however, no quantitative estimates of statistical support w...

Background: Peptic ulcers occur in that part of the gastrointestinal tract which is exposed to gastric acid and pepsin, i.e., the stomach and duodenum. Gastric and duodenal ulcers are common pathologies that may be induced by a variety of factors such as stress, smoking and noxious agents including non-steroidal anti-inflammatory drugs. Ipomoea batatas tubers (sweet potato) contain ample amount...

The theory of atherosclerosis based on the inflammation caused by endothelial dysfunction, lipid infiltration, free radicals and inflammatory processes immunologic. The activate NFkB and induces the formation of proteins that enhance the immune system in atherosclerosis progression. Prevention efforts done through drugs or fitofarmaka, one of the herbs that contain anthocyanins which act as ant...

Floral attributes evolve in response to frequent and efficient pollinators, which are potentially important drivers of floral diversification and reproductive isolation. In this context, we asked, how do flowers evolve in a bat-hummingbird pollination system? Hence, we investigated the pollination ecology of two co-flowering Ipomoea taxa (I. marcellia and I. aff. marcellia) pollinated by bats a...

Volatile fatty acids (VFAs), comprising mainly of acetic acid and lesser quantities of propionic and butyric acids, are generated when zoomass or phytomass is acted upon by acidogenic and acetogenic microorganisms. VFAs can be utilized by methanogens under anaerobic conditions to generate flammable methane-carbon dioxide mixtures known as 'biogas'. Acting on the premise that this manner of VFA ...

Plant transcription factors often contain domains that evolve very rapidly. Although it has been suggested that this rapid evolution may contribute substantially to phenotypic differentiation among species, this suggestion has seldom been tested explicitly. We tested the validity of this hypothesis by examining the rapidly evolving non-DNA-binding region of an R2R3-myb transcription factor that...

Three new species of Kerria Targioni-Tozzetti from India, namely Kerria pennyae Ahmad & Ramamurthy sp. nov. on Schleichera oleosa from Orissa, Kerria dubeyi Ahmad & Ramamurthy sp. nov. on Ficus bengalensis from Bangalore and Kerria varshneyi Ahmad & Ramamurthy sp. nov. on Ziziphus mauritiana from Punjab are described and illustrated, and a key is provided to species of Kerria known from India.

this study investigated the effects of the dietary supplementation of zizyphus mauritianaleaf meal (zlm) on the performance of yankasa lambs. twenty five lambs aged between 6 and 8 months were randomly divided into five groups of five animals each in a completely randomized design to receive supplementary diets containing 0, 10, 20, 30 and 40% zlm as replacement for cotton seed cake in concentr...

Two genes encoding protein components of the nuclear pore complex Nup160 and Nup96 cause lethality in F2-like hybrid genotypes between Drosophila simulans and Drosophila melanogaster. In particular, D. simulans Nup160 and Nup96 each cause inviability when hemizygous or homozygous in species hybrids that are also hemizygous (or homozygous) for the D. melanogaster X chromosome. The hybrid lethali...
