RESUMO
Clinical trials face many challenges with meeting projected enrollment and retention goals. A study's recruitment materials and messaging convey necessary key information and therefore serve as a critical first impression with potential participants. Yet study teams often lack the resources and skills needed to develop engaging, culturally tailored, and professional-looking recruitment materials. To address this gap, the Recruitment Innovation Center recently developed a Recruitment & Retention Materials Content and Design Toolkit, which offers research teams guidance, actionable tips, resources, and customizable templates for creating trial-specific study materials. This paper seeks to describe the creation and contents of this new toolkit.
RESUMO
This study provides a microanalytical characterization of pigment fragments from the painting "Allegory to the Arts" and two portraits, "Rubens" and "Tintoretto," by Léon Pallière. The fragments were surface-analyzed using several near-surface methods to acquire information on the materials and determine the painting techniques utilized before the restoration. Scanning electron microscopy/energy-dispersive X-ray spectrometry (SEM/EDS), Raman spectroscopy coupled to an optical microscope (Raman microprobe), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR) revealed organic materials, hydrocerussite (Pb3(CO3)2(OH)2), cerussite (PbCO3), zincite (ZnO), chalcopyrite (CuFeS2), nepheline (K(Na,K)3AlSi4O16), calcite (CaCO3), brookite (TiO2), kinoshitalite (Ba3(Si2Al2)O10(OH)2), hematite (Fe2O3), barium magnesium silicate (Ba2Mg(Si2O7)), and aluminosilicates. Also identified were vermilion/cinnabar (HgS), copper phthalocyanine blue (C32H16CuN8), and mendipite (Pb3Cl2O2), in addition to the use of gold leaf in one of the artworks. SEM/EDS provided information on the chemical composition and surface morphology of the fragments, and XRD revealed crystalline raw materials (minerals or their synthetic analogs) used in the paintings. Raman microprobe was particularly useful in identifying pigments, providing a uniquely specific and sensitive means of identifying inorganic and organic compounds.
RESUMO
Bones of human and ground sloth remains were analyzed for presence of Trypanosoma cruzi by conventional PCR using primers TC, TC1 and TC2. Sequence results amplified a fragment with the same product size as the primers (300 and 350pb). Amplified PCR product was sequenced and analyzed on GenBank, using Blast. Although these sequences did not match with these parasites they showed high amplification with species of bacteria. This article presents the methodology used and the alignment of the sequences. The display of this dataset will allow further analysis of our results and discussion presented in the manuscript "Finding the unexpected: a critical view on molecular diagnosis of infectious diseases in archaeological samples" (Pucu et al. 2017) [1].
