TL;DR: It is revealed that ribosomal RNA 2′-O-methylation can be modulated in human ribosomes, including at key functional sites for translation, and that changes in the 2′'-O- methylation pattern control the intrinsic capabilities of ribosome to translate mRNAs.
Abstract: Ribosomal RNAs (rRNAs) are main effectors of messenger RNA (mRNA) decoding, peptide-bond formation, and ribosome dynamics during translation. Ribose 2′-O-methylation (2′-O-Me) is the most abundant rRNA chemical modification, and displays a complex pattern in rRNA. 2′-O-Me was shown to be essential for accurate and efficient protein synthesis in eukaryotic cells. However, whether rRNA 2′-O-Me is an adjustable feature of the human ribosome and a means of regulating ribosome function remains to be determined. Here we challenged rRNA 2′-O-Me globally by inhibiting the rRNA methyl-transferase fibrillarin in human cells. Using RiboMethSeq, a nonbiased quantitative mapping of 2′-O-Me, we identified a repertoire of 2′-O-Me sites subjected to variation and demonstrate that functional domains of ribosomes are targets of 2′-O-Me plasticity. Using the cricket paralysis virus internal ribosome entry site element, coupled to in vitro translation, we show that the intrinsic capability of ribosomes to translate mRNAs is modulated through a 2′-O-Me pattern and not by nonribosomal actors of the translational machinery. Our data establish rRNA 2′-O-Me plasticity as a mechanism providing functional specificity to human ribosomes.

TL;DR: In this article, the impact of unions on productivity was explored using meta-analysis and meta-regression analysis, and it was shown that most of the variation in published results is due to specification differences between studies.
Abstract: The impact of unions on productivity is explored using meta-analysis and meta-regression analysis. It is shown that most of the variation in published results is due to specification differences between studies. After controlling for differences between studies, a negative association between unions and productivity is established for the United Kingdom, whereas a positive association is established for the United States in general and for U.S. manufacturing.

TL;DR: In this paper, the authors highlight the recent findings (2010-2012) and mechanisms behind EDTA-enhanced (1) solubilization of heavy metals in soil, (2) mobilization/transport of soluble metals towards plant root zone, and (3) metal absorption by plant roots and translocation towar
Abstract: The increase in heavy metal terrestrial ecosystems’ contamination through anthropogenic activities is a widespread and serious global problem due to their various environmental and human implications. For these reasons, several techniques, including phytoremediation of heavy metals, have been extensively studied. In spite of significant recent advancement, ethylene diamine tetraacetic acid (EDTA)-enhanced heavy metal phytoextraction as well as related ecological risks are still topical and remain an important area of research. In fact, EDTA favors the solubilization of metals and metalloids in soils, and was therefore extensively studied during the last two decades in order to improve phytoextraction efficiency and reduce treatment duration. This review highlights the recent findings (2010–2012) and mechanisms behind EDTA-enhanced (1) solubilization of heavy metals in soil, (2) mobilization/transport of soluble metals towards plant root zone, and (3) metal absorption by plant roots and translocation towar...

TL;DR: Tannins as herbal extracts are a good alternative for green chemistry and are found aplenty in some plant species and can be extracted by simple methods as discussed by the authors, however, their main feature and advantage is their phenolic structure which is very similar to synthetic phenols.

TL;DR: In this paper, a joint experimental and theoretical study for the electronic structures of copper oxides including CuO, and the metastable mixed-valence oxide (MVO) was presented.
Abstract: A joint experimental and theoretical study is presented for the electronic structures of copper oxides including $\mathrm{C}{\mathrm{u}}_{2}\mathrm{O}$, CuO, and the metastable mixed-valence oxide $\mathrm{C}{\mathrm{u}}_{4}{\mathrm{O}}_{3}$. The optical band gap is determined by experimental optical absorption coefficient, and the electronic structure in valence and conduction bands is probed by photoemission and electron energy loss spectroscopies, respectively. The experimental results are compared with many-body $GW$ calculations utilizing an additional on-site potential for $d$-orbital energies that facilitates tractable and predictive computations. The side-by-side comparison between the three oxides, including a band insulator $(\mathrm{C}{\mathrm{u}}_{2}\mathrm{O})$ and two Mott/charge-transfer insulators (CuO, $\mathrm{C}{\mathrm{u}}_{4}{\mathrm{O}}_{3})$ leads to a consistent picture for the optical and band-structure properties of the Cu oxides, strongly supporting indirect band gaps of about 1.2 and 0.8 eV in CuO and $\mathrm{C}{\mathrm{u}}_{4}{\mathrm{O}}_{3}$, respectively. This comparison also points towards surface oxidation and reduction effects that can complicate the interpretation of the photoemission spectra.
