Failure to address the putative etiologic and pathophysiologic heterogeneity of the schizophrenia syndrome and problems in definitive assessment of human brain function have impaired progress in schizophrenia research. New approaches to psychopathology and converging evidence from antemortem and postmortem study can now result in more decisive study of the neuroanatomy and neuropathology of schizophrenia.

REEs in wetland sediments from the Oaxaca coast in southern Mexico were used to infer the sources and depositional processes by involving both the geochemical characteristics and geostatistical approaches. Statistically strong positive correlation between REEs confirmed similar origin in all the cores. Light REEs (LREEs) represented >84 % of ΣREE mean concentrations varies between 47.

Performing automatic and standardized 4D TEE segmentation and mitral valve analysis is challenging due to the limitations of echocardiography and the scarcity of manually annotated 4D images. This work proposes a semi-supervised training strategy using pseudo labelling for MV segmentation in 4D TEE; it employs a Teacher-Student framework to ensure reliable pseudo-label generation. 120 4D TEE recordings from 60 candidates for MV repair are used.

Prader-Willi syndrome (PWS) is a genetic disorder associated with baseline respiratory impairment caused by multiple contributing etiologies. While this may be expected to increase the risk of severe COVID-19 infections in PWS patients, survey studies have suggested paradoxically low disease severity. To better characterize the course of COVID-19 infection in patients with PWS, this study analyses the outcomes of hospitalizations for COVID-19 among patients with and without PWS.

is a rare Coffea species boasting a flavor profile comparable to Arabica coffee () and has a good adaptability to lowland tropical climates. This species faces increasing threats from climate change, deforestation, and habitat fragmentation in its West African homeland. Using 1037 novel SNP markers derived from Genotyping-by-Sequencing (GBS), we revealed the presence of three distinct natural populations (mean Fst = 0.

Medulloblastoma (MB) is an aggressive pediatric brain tumor with distinct molecular heterogeneity. Identifying subtype-specific signatures within Group 3 and Group 4 remains challenging due to shared cytogenetic alterations and limitations of conventional differential gene expression analysis. To uncover the underlying molecular signatures and hidden regulators, we used the Cavalli transcriptomic profile of 470 Group 3 and Group 4 MB patients to reconstruct subtype-specific regulatory networks.
