Buprestidae (Coleoptera) from Oaxaca State, Mexico.

A checklist with 246 species, three subspecies, 37 genera, 19 tribes, and four subfamilies of Buprestidae and their distribution in the state of Oaxaca is provided. Acmaeodera crossi Barr, 1992, Chrysobothris viridiimpressa Gory & Laporte, 1837 and Melanophila atra Gory, 1841 are recorded for the first time in the state. Leucaena esculenta (DC.

Direct visualization of emergent metastatic features within an ex vivo model of the tumor microenvironment.

Ischemic conditions such as hypoxia and nutrient starvation, together with interactions with stromal cells, are critical drivers of metastasis. These conditions arise deep within tumor tissues, and thus, observing nascent metastases is exceedingly challenging. We thus developed the 3MIC-an ex vivo model of the tumor microenvironment-to study the emergence of metastatic features in tumor cells in a 3-dimensional (3D) context.

Ionic Bent-Core Pillar[]arenes: From Liquid Crystals to Nanoaggregates and Functional Applications.

Herein, we report the first examples of supramolecular systems from bent-core-based pillar[]arenes through ionic bonds. These ionic materials have been prepared by the interaction of an amino-ended pillar[5]arene (P5N10) and three different carboxylic acids, including bent-core moieties. The bent-core units are based on ester, biphenyl, and azobenzene structures bearing two different flexible spacers between the carboxyl group and the central bent-core aromatic units.

Modulating the Conductivity of Light-Responsive Ionic Liquid Crystals.

In this work, we describe the phase behaviour and the dielectric and conductivity response of new light-responsive ionic liquid crystals, ILCs, which can be applied as controllable electrolytes. The materials include two different dicationic viologens, the asymmetric 6BP18 and the symmetric EV2ON(Tf), containing bistriflimide as the counterions, mixed with 5% and 50% molar, respectively, of one new photoresponsive mesogen called CNAzO14. These mixtures exhibit liquid crystal behaviour, light responsiveness through the - photoisomerisation of the azobenzene groups in CNAzO14, and strong dielectric responses.

Investigating the 2023 MOGAD Criteria in Children and Adults With MOG-Antibody Positivity Within and Outside Attacks.

Background And Objectives: The 2023 criteria for myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) perform well in adults but have not been assessed in children.

Methods: This prospective observational nationwide study includes children and adults with demyelinating syndromes or encephalitis, whose serum or CSF was found MOG-immunoglobulin G (IgG) positive at Institut d'Investigacions Biomèdiques August Pi i Sunyer-Hospital Clínic of Barcelona (Spain). Exclusion criteria were lack of clinical information and follow-up <1 year, and serum unavailable for antibody testing.
