Expression of key unfolded proteinresponse genes predicts patient survivaland an immunosuppressive microenvironmentin glioblastoma
(2024) [Artículo de periódico]Background Dysregulation of cellular processes related to protein folding and trafficking leads to the accumulation of misfolded proteins in the endoplasmic reticulum (ER), triggering ER stress. Cells cope with ER stress ... -
Spore wall cytochemistry and structure in five species of the liverwort Riccia (Ricciaceae)
(2024) [Artículo de periódico]The spore wall of Riccia plano-biconvexa, R. fruchartii, R. cavernosa, R. stenophylla, and R. curtisii was analyzed using light microscopy. The study involved cytochemical analysis to distinguish the different layers of ... -
Pollen morphology in the genus Dyckia (Bromeliaceae): endemic species from southern Brazil comprising the proposed infrageneric grouping “D. selloa complex”
(2024) [Artículo de periódico]Dyckia, belonging to the Bromeliaceae, consists of species that share several morphological similarities. Recently, a proposal has grouped 13 species of the genus into a “D. selloa complex” based on their limited geographical ... -

CD73 mitigates ZEB1 expression in papillary thyroid carcinoma
(2024) [Artículo de periódico]Background: ZEB1, a core transcription factor involved in epithelial-mesenchymal transition (EMT), is associated with aggressive cancer cell behavior, treatment resistance, and poor prognosis across various tumor types. ... -
Comparative microbiome analysis in cystic fbrosis and non-cystic fbrosis bronchiectasis
(2024) [Artículo de periódico]Background: Bronchiectasis is a condition characterized by abnormal and irreversible bronchial dilation resulting from lung tissue damage and can be categorized into two main groups: cystic fibrosis (CF) and non-CF ... -
Bovine alphaherpesvirus 1, bovine alphaherpesvirus 5 and bubaline alphaherpesvirus 1 in palatine tonsils from water buffaloes in Northern Brazil and possible links with the origin of bovine alphaherpesvirus type 5
(2024) [Artículo de periódico]Herpesviruses are significant pathogens of ruminants. In buffalo cattle, herpesviruses have not been thoroughly studied. The aim of this study was to investigate the occurrence of bubaline alphaherpesvirus 1 (BuAHV1), ... -
The osmoregulated metabolism of trehalose contributes to production of type 1 fimbriae and bladder colonization by extraintestinal Escherichia coli strain BEN2908
(2024) [Artículo de periódico]In Escherichia coli, the disaccharide trehalose can be metabolized as a carbon source or be accumulated as an osmoprotectant under osmotic stress. In hypertonic environments, E. coli accumulates trehalose in the cell by ... -
Função do ventrículo direito e estresse oxidativo melhoram com a administração de hormônios da tireoide e suco de uva em um modelo de hipertensão pulmonar
(2024) [Artículo de periódico]Fundamento: A remodelação adversa dos vasos pulmonares eleva a pressão pulmonar e provoca hipertensão arterial pulmonar (HAP). A HAP resulta em aumento da pós-carga do ventrículo direito (VD), causando hipertrofia ventricular ... -
