Building the evidence base for dengue vector control: searching for certainty in an uncertain world.

Pathog Glob Health 2018 Dec 6:1-9. Epub 2018 Dec 6.

a Heidelberg Institute of Global Health , University of Heidelberg , Germany.

This review discusses biological and chemical methods for dengue vector control, using recently emerging summary evidence, meta-analyses and systematic reviews to conclude on practical public health recommendations for Aedes control, which is increasingly relevant in an era of widespread Chikungunya, yellow feer and Zika outbreaks. The analysis follows an a priori framework of systematic reviews by the authors on vector control methods, distinguishing vector control methods into biological, chemical and environmental methods. Findings of each published systematic review by the authors, following each individual vector control method, are summarised and compared in the discussion against the findings of existing meta-analyses covering all vector control methods.

Reversible complexation of ammonia by breaking a manganese-manganese bond in a manganese carbonyl ethylenedithiolate complex: a theoretical study of an unusual type of Lewis acid.

Dalton Trans 2018 Dec 6. Epub 2018 Dec 6.

Department of Chemistry, University of Georgia, Athens, Georgia 30602, USA.

The reaction of Mn(CO)5Br with sodium ethylenedithiolate was reported in 1968 to give a dark red binuclear H2C2S2Mn2(CO)6 complex possessing the unusual property of complexing reversibly with ammonia to give a yellow H2C2S2Mn2(CO)6·NH3 adduct. In order to provide some insight into the nature of this adduct, density functional studies were performed on the H2C2S2Mn2(CO)n (n = 4 to 8) systems as well as their relevant ammonia and trimethylphosphine adducts. These theoretical studies support the structure of H2C2S2Mn2(CO)6 originally suggested 50 years ago involving the binding of the ethylenedithiolate C[double bond, length as m-dash]C double bond as well as the sulfur atoms to the Mn2 unit with a bonding Mn-Mn distance of ∼2.

Xanthommatin-Based Electrochromic Displays Inspired by Nature.

ACS Appl Mater Interfaces 2018 Dec 3. Epub 2018 Dec 3.

Department of Chemistry and Chemical Biology , Northeastern University , Boston , Massachusetts 02115 , United States.

Color is a signature visual feature in nature; however, the ability to trigger color change in the presence of different environmental stimuli is unique to only a handful of species in the animal kingdom. We exploit the natural color-changing properties of the predominant pigment in arthropods and cephalopods-xanthommatin (Xa)-and describe its utility as a new broad-spectrum electrochromic material. To accomplish this goal, we explored the spectroelectrochemical properties of Xa adsorbed to an indium-doped tin oxide-coated substrate chemically modified with poly(3,4-ethylene dioxythiophene) doped with poly(styrenesulfonate) (PEDOT:PSS).

Three Zn(II) complexes, [Zn(HL)(NO)]·HO (1), [(ZnL)(μ-OH)](NO)·0.5HO (2), and [(ZnL)( o-van)(μ-OCH)(μ-OH)](NO) (3), have been synthesized by exploiting the flexidentate nature of a multidentate Schiff base ligand, HL ( N, N'-bis(3-methoxysalicylidene)diethylenetriamine), by changing the reaction conditions and stoichiometry of the reactants. All three complexes are highly fluorescent in solution as well as in solid and have been used as luminescence sensors toward nitrophenol explosives in both the media. Read More

Hormetic effects of curcumin: What is the evidence?

J Cell Physiol 2018 Dec 4. Epub 2018 Dec 4.

Biotechnology Research Center, Pharmaceutical Technology Institute, Mashhad University of Medical Sciences, Mashhad, Iran.

Curcumin (diferuloylmethane), a component of the yellow powder prepared from the roots of Curcuma longa or Zingiberaceae (known as turmeric) is not only widely used to color and flavor food but also used as a pharmaceutical agent. Curcumin demonstrates anti-inflammatory, anticarcinogenic, antiaging, and antioxidant activity, as well as efficacy in wound healing. Notably, curcumin is a hormetic agent (hormetin), as it is stimulatory at low doses and inhibitory at high doses. Read More

Proliferation characteristics of cells cultured under periodic versus static conditions.

Cytotechnology 2018 Dec 4. Epub 2018 Dec 4.

Cellasys GmbH, Kronburg, Germany.

In vitro culture models have become an indispensable tool for assessing a vast variety of biological questions in many scientific fields. However, common in vitro cultures are maintained under static conditions, which do not reflect the in vivo situation and create a non-physiological environment. To assess whether the growth characteristics of cells cultured at pulsed-perfused versus static conditions differ, we observed the growth of differentially cultured cells in vitro by life-cell time-lapse imaging of recombinant HEK293 cells, stably expressing yellow fluorescent protein.

The proton and metal binding sites responsible for the pH-dependent green-red bioluminescence color tuning in firefly luciferases.

Sci Rep 2018 Dec 4;8(1):17594. Epub 2018 Dec 4.

Laboratório Nacional de Biociências (LNBio), Centro Nacional de Pesquisa em Energia e Materiais (CNPEM), Campinas, SP, Brazil.

Firefly luciferases produce yellow-green light under physiological and alkaline conditions, however at acidic pH, higher temperatures or in the presence of heavy metals the color changes to red, a property called pH-sensitivity. Despite many decades of studies, the proton and metal binding sites responsible for pH-sensitivity remain enigmatic. Previously we suggested that the salt bridge E311/R337 keeps a closed conformation of the luciferin phenolate binding site. Read More

Manufacture of Sustainable Clay Bricks Using Waste from Secondary Aluminum Recycling as Raw Material.

Materials (Basel) 2018 Dec 2;11(12). Epub 2018 Dec 2.

Department of Chemical, Environmental and Materials Engineering, Universidad de Jaén, Campus Las Lagunillas, s/n, 23071 Jaén, Spain.

The aluminum recycling industry produces aluminum filter dust (AFD), a waste byproduct of the aluminum recycling process composed mainly of aluminum oxide in a percentage between 60⁻70%, 8% calcium oxide, almost 15% sodium chloride, and between 5⁻10% potassium chloride. Due to its aluminum content, this waste can be used as a raw material in the manufacture of ceramic bricks, at the same time reducing the environmental impact produced in landfill. In this work, the partial substitution of a clay mixture (40% black, 30% red, and 30% yellow clay) by different proportions of AFD in the range 0⁻25 wt % for the production of fired clay brick was studied.
