Siderophile element systematics of IAB complex iron meteorites: New insights into the formation of an enigmatic group.

Geochim Cosmochim Acta 2016 Aug 21;188:261-283. Epub 2016 May 21.

Department of Geology, University of Maryland, College Park, MD 20742, USA.

Siderophile trace element abundances and the Re-Os isotopic systematics of the metal phases of 58 IAB complex iron meteorites were determined in order to investigate formation processes and how meteorites within chemical subgroups may be related. Close adherence of Re-Os isotopic data of most IAB iron meteorites to a primordial isochron indicates that the siderophile elements of most members of the complex remained closed to elemental disturbance soon after formation. Minor, presumably late-stage open-system behavior, however, is observed in some members of the sLM, sLH, sHL, and sHH subgroups. Read More

The The influence of high doses of α-tocopherol on the content of selected trace elements in the liver of developing chicken embryos in experimentally induced 2,3,7,8-tetrachlorodibenzo-p-dioxin intoxication.

Acta Biochim Pol 2019 Apr 13. Epub 2019 Apr 13.

Institute of Low Temperature and Structure Research, Polish Academy of Sciences, Wrocław, Poland.

A chicken embryo develops in ovo without access to a constant circulating maternal nutrient supply, and therefore all necessary nutrients are initially stored in the yolk, and with progressive development are transferred to the liver, where they are taken up in response to various needs. Fluctuations in hepatic trace elements correlate with their mobilization from egg stores. 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) intoxication causes liver damage by production of free radicals, while α-tocopherol is a well-known antioxidant and may play a protective role.

Entrepreneurial ecosystems: economic, technological, and societal impacts.

J Technol Transf 2019 15;44(2):313-325. Epub 2018 Sep 15.

5School of Economics and Business Administration, Friedrich Schiller University Jena, Carl-Zeiss-Str. 3, 07743 Jena, Germany.

Despite the overwhelming use of the metaphor 'ecosystem' in academia, industry, policy, and management, exact definitions of what 'ecosystems' really comprise are scarce and often inconsistent. Existing vague descriptions in the literature do not consider the boundaries of respective agglomerations, hence, they impede the evaluation of performance and outcome measures of respective ecosystems. This special issue is a first attempt to trace the 'ecosystem' discussion back to its roots-the ancient , coined by the Greek philosopher Hesiod (700 BC), and aims to critically reflect on the usage of the term 'ecosystem', briefly summarize the extant literature and grasp the main features of entrepreneurial ecosystems, namely the economic, technological, and societal dimensions of entrepreneurial ecosystems.

Environ Sci Pollut Res Int 2019 Apr 4. Epub 2019 Apr 4.

Center for Preventive Medical Sciences, Chiba University, Inage-ku Yayoi-cho 1-33, Chiba, Japan.

Maternal exposure to high levels of persistent organic pollutants (POPs) and trace elements is an important concern for fetal growth. In our previous study, we showed the polychlorinated biphenyl (PCB) levels in maternal serum from the Chiba Study of Mother and Child Health (C-MACH) cohort and their relationships between PCB levels in cord serum with birth weight of newborn. Various reports on the relationship between chemical exposure and birth status have been published; however, studies that analyze the effects of both PCB and metal exposure together in one cohort are still limited.

IntronDB: a database for eukaryotic intron features.

Authors:
Dapeng Wang

Bioinformatics 2019 Apr 5. Epub 2019 Apr 5.

Department of Plant Sciences, University of Oxford, S Parks Rd, Oxford OX1 3RB, UK.

Summary: The rate and extent of unbalanced eukaryotic intron changes exhibit dynamic patterns for different lineages of species or certain functional groups of genes with varied spatio-temporal expression modes affected by selective pressure. To date, only a few key conserved splicing signals or regulatory elements have been identified in introns and little is known about the remaining intronic regions. To trace the evolutionary trajectory of spliceosomal introns from available genomes under a unified framework, we present IntronDB, which catalogues approximately 50000000 introns from over 1000 genomes spanning the major eukaryotic clades in the tree of life.

The essential metals for humans: a brief overview.

J Inorg Biochem 2019 Mar 22;195:120-129. Epub 2019 Mar 22.

Department of Life and Environmental Sciences, University of Cagliari, Italy.

The human body needs about 20 essential elements in order to function properly and among them, for certain, 10 are metal elements, though for every metal we do need, there is another one in our body we could do without it. Until about 1950 poor attention was given to the so-called "inorganic elements" and while researches on "organic elements" (C, N, O and H) and organic compounds were given high priority, studies on essential inorganic elements were left aside. Base on current knowledge it is ascertained today that metals such as Na, K, Mg, Ca, Fe, Mn, Co, Cu, Zn and Mo are essential elements for life and our body must have appropriate amounts of them.
