Cryogenic, but not hypothermic, preservation disrupts the extracellular matrix of cell sheets.

Cell sheet (CS)-based approaches hold significant potential for tissue regeneration, relying on the extracellular matrix (ECM) for success. Like in native tissues, the ECM provides structural and biochemical support for cellular homeostasis and function. Effective preservation strategies that maintain ECM integrity are critical to enhance the therapeutic potential of CS-based approaches.

Treatment of Post-Septal Orbital Cellulitis due to Odontogenic Infection.

Orbital cellulitis happens when the region behind the orbital septum is affected. It consists an urgency because of its potential risks of complications, such as vision loss, cavernous sinus thrombosis, or Lemierre Syndrome. This article reports a case of a subperiosteal and orbital cellulitis, which had a periapical lesion in the left first molar as it´s focus.

Investigation of RNA Viruses in Latreille, 1809 (Diptera: Ceratopogonidae) in a Mining Complex in the Southeastern Region of the Brazilian Amazon.

The biting midges Latreille, 1809 (Diptera: Ceratopogonidae) is highly relevant to epidemiology and public health, as it includes species that are potential vectors of human and animal arboviruses. The aim of this study was to investigate the presence of RNA viruses in species of the genus collected in the Carajás mining complex in the state of Pará. The biting midges were collected in the municipalities of Canaã dos Carajás, Curionópolis and Marabá and morphologically identified.

Mapping Thrombosis Serum Markers by H-NMR Allied with Machine Learning Tools.

Machine learning and artificial intelligence tools were used to investigate the discriminatory potential of blood serum metabolites for thromboembolism and antiphospholipid syndrome (APS). H-NMR-based metabonomics data of the serum samples of patients with arterial or venous thromboembolism (VTE) without APS (n = 32), thrombotic primary APS patients (APS, n = 32), and healthy controls (HCs) (n = 32) were investigated. Unique metabolic profiles between VTE and HCs, APS and HCs, and between VTE and triple-positive APS groups were indicative of the significant alterations in the metabolic pathways of glycolysis, the TCA cycle, lipid metabolism, and branched-chain amino acid (BCAA) metabolism, and pointed to the complex pathogenesis mechanisms of APS and VTE.
