The Probability Distribution Of Distance Tss-Tls Is Organism Characteristic And Can Be Used For Promoter Prediction, Yun Dai, Ren Zhang, Yan-Xia Lin
Associate Professor Yan-Xia Lin
Transcription is a complicated process which involves the interactions of promoter cis-elements with multiple trans-protein factors. The specific interactions rely not only on the specific sequence recognition between the cis- and trans-factors but also on certain spatial arrangement of the factors in a complex. The relative positioning of involved cis-elements provides the framework for such a spatial arrangement. The distance distribution between gene transcription and translation start sites (TSS-TLS) is the subject of the present study to test an assumption that over evolution, the TSS-TLS distance becomes a distinct character for a given organism. Four representative organisms (Escherichia cloi, Saccharomyces …
Tissue Distribution Of Lignans In Rats In Response To Diet, Dose-Response, And Competition With Isoflavones, Timothy Murray, J. Kang, Lee Astheimer, William E. Price
Tissue Distribution Of Lignans In Rats In Response To Diet, Dose-Response, And Competition With Isoflavones, Timothy Murray, J. Kang, Lee Astheimer, William E. Price

This paper investigates the occurrence and distribution of the lignan metabolites enterodiol (END) and enterolactone (ENL) and the isoflavone daidzein (DAID) in rat tissues using liquid chromatography - electrospray ionisation mass spectrometry (LC – ESI/MSn) following a variety of dietary regimes. Further, we examined the dose-response and distribution of END and ENL in liver, testes, prostate and lung, and investigated the effects of competition between lignans and isoflavones on metabolite distribution. In liver, testes, prostate & lung tissue, dose related increases in END concentration were observed. In the testes, the co-administration of 60 mg/kg SDG with 60 mg/kg isoflavones produced …

Evidence For Specific Subunit Distribution And Interactions In The Quaternary Structure Of Α-Crystallin, Amie M. Morris, J Andrew Aquilina
Evidence For Specific Subunit Distribution And Interactions In The Quaternary Structure Of Α-Crystallin, Amie M. Morris, J Andrew Aquilina
J. A. Aquilina
The quaternary structure of alpha-crystallin is dynamic, a property which has thwarted crystallographic efforts towards structural characterization. In this study, we have used collision-induced dissociation mass spectrometry to examine the architecture of the polydisperse assemblies of alpha-crystallin. For total alpha-crystallin isolated directly from fetal calf lens using size-based chromatography, the alpha B-crystallin subunit was found to be preferentially dissociated from the oligomers, despite being significantly less abundant overall than the alpha A-crystallin subunits. Furthermore, upon mixing molar equivalents of purified alpha A- and alpha B-crystallin, the levels of their dissociation were found to decrease and increase, respectively, with time. Interestingly …

Ochotona Daurica Pallas, 1776: Modern And Past Distribution Area In Mongolia And The Transbaikal Region, M. A. Erbjeva, N. V. Alexeeva, T. V. Kisloschaeva
Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
Ochotona daurica Pallas, 1776 is one of the ancient species among modern taxa having an origination in Transbaikalia possible at the end of Pleistocene. Review on the Late Pleistocene- Holocene-Recent area of distribution of this species is given on the base of new evidences and detail analysis of the previous data.

With the involvement of the World Bank, Zoological Society of London, Dutch Government and National University of Mongolia, the volumes of Mongolian Red Lists of Fish, Amphibians and Reptiles, Birds and Mammals were completed, and Mongolia is now among the few nations that have up-to-date conservation assessments for all vertebrates. Of the 476 assessed native bird species of Mongolia, 10% were categorized as regionally threatened including Near Threatened. A further 0.6% were categorized as Critically Endangered (CR), 1.7% as Endangered (EN), 3.3% as Vulnerable (VU), and 4.4% as Near Threatened (NT). Almost 90% of Mongolian birds are categorized as Least …

Methods to incorporate spatial context into species distribution models (SDMs) are underutilised, with predictions usually based only on environmental space and ignoring geographic space. The goals of this study were to demonstrate a relatively simple post-hoc method to include spatial context in SDMs and to quantify the improvement over purely niche-based models. The method involved producing a standard niche-based model using established techniques, such as Maxent, and then calculating the neighbourhood average of the model output in geographic space. In effect, we tested whether the spatially averaged model output was better at predicting species distributions than the raw model output. …

The detailed analyses of the volatile essential oil and lipid profiles of the aerial parts from the blooming and fruit-forming stages of both ripe and unripe fruit of Lycopus europaeus (Lamiaceae) are presented. Both of these profiles are distinguished by components with a restricted occurrence in the Plant Kingdom. These rare compounds include (E)-hotrienol in the volatiles, numerous unusual fatty acids (such as very long chain, odd-numbered and branched-chain) in the bound lipids and a high amount of iso- and anteiso-alkanes in the epicuticular waxes. Furthermore, a Gaussian-like distribution of the relative amounts of the epicuticular wax alkanes was observed. …
