Synthesis and characterisation of ionic liquid crystals based on substituted pyridinium cations

Andreia F. M. Santos, Carlos Cruz, Maria H. Godinho, Madalena Dionísio, João L. Figueirinhas & Luis C. Branco
Novel ionic liquid crystals based on pyridinium and methylpyridinium cations with a dodecyl chain and bromide as anion have been prepared and characterised. [C12Pyr][Br] and [C12-n-Pic][Br] (n = 2, 3 or 4) were studied in order to understand the influence of the methyl group position in the mesomorphic behaviour. Neat microwave-assisted reactions were carried out to synthesised [C12Pyr][Br], [C12-3-Pic][Br] and [C12-4-Pic][Br] as a sustainable approach, leading to significantly reduced reaction times (35 min vs. 48...

Etnoarqueología para el combate a la pobreza: la estrategia ignorada por el estado Mexicano

Sandra L. López Varela
pp. 195-211 Alexander von Humboldt (1988 [1811]) describes in his Essai Politique sur le Royaume de la Nouvelle Espagne, the landscape of social inequality that existed in New Spain in terms of the distribution of wealth, civilization and soil cultivation during the reign of Charles IV. For more than two centuries, the Mexican government has tried unsuccessfully to revert social end economic inequality through economic growth and development policies. In the following pages, I discuss...

Anti-inflammatory and anti-allodynic activities in mice of the essential oil and desmethylisoencecalin from Zinnia grandiflora Nuttall

Valeria Reyes-Pérez, Vinicio Granados-Soto, Edelmira Linares, Robert Bye, Rachel Mata & Myrna Deciga-Campos
Zinnia grandiflora (Asteraceae) is used to alleviate several painful disorders. The effects of an essential oil prepared by hydrodistillation from Z. grandiflora (EOZ) and its major compound on neuropathic pain, allodynia, and inflammation in mice were assessed. Headspace-solid phase microextraction analysis of an aqueous extract was also carried out. GC-MS analyses of all volatiles revealed that germacrene D (13.24%) and desmethylisoencecalin (DME) (13.24%) were the most abundant compounds. EOZ was effective in reducing inflammation and...

The resolution of fluorescence microscopy images is limited by the physical properties of light. In the last decade, numerous super-resolution microscopy (SRM) approaches have been proposed to deal with such hindrance. Here we present Mean-Shift Super Resolution (MSSR), a new SRM algorithm based on the Mean Shift theory, which extends spatial resolution of single fluorescence images beyond the diffraction limit of light. MSSR works on low and high fluorophore densities, is not limited by the...

Currently, there is scant information regarding the features associated to the persistence of post-COVID-19 syndrome, which is the main aim of the present study. A cohort study of 102 COVID-19 patients was conducted. The post-COVID-19 symptoms were assessed by a standardised questionnaire. Lymphocyte immunophenotyping was performed by flow cytometry and chemokines/cytokines, neutrophil extracellular traps, the tripartite motif 63, anti-cellular, and anti-SARS-CoV-2 IgG antibodies were addressed in serum. The primary outcome was the persistence of post-COVID-19...

Temperature and frequency-dependent magnetic susceptibility parameters: improving the reliability of archaeointensity in burnt clay ceramics

Arnaldo Hernández Cardona & Luis M. Alva Valdivia
Analysis of magnetic mineralogy alteration parameters has been used to understand mineralogy transformation at sample heating. While many studies used the reversibility of low-field magnetic susceptibility vs. temperature κ(T) curves in a qualitative sense to select material for paleomagnetic studies, few parameters have been developed to assess a quantitative description. This work aims to correlate the magnetic mineral properties deduced by susceptibility experiments of archaeological ceramics (burnt clay) during the heating steps of the Thellier-Thellier...

El Camino Tierra Adentro as a rural landscape

Graciela Mota, Pilar Rincón & Sara E. Narvaez Martínez
Camino Real de Tierra Adentro was the Royal Inland Road, also known as the Silver Route. The inscribed property consists of 55 sites and five existing World Heritage sites lying along a 1400 km section of this 2600 km route, that extends north from Mexico City to Texas and New Mexico, United States of America. The route was actively used as a trade route for 300 years, from the mid-16th to the 19th centuries, mainly...
