SinEx DB 2.0 update 2020: database for eukaryotic single-exon coding sequences
(Oxford University Press, 2021-01-28)Single-exon coding sequences (CDSs), also known as 'single-exon genes' (SEGs), are defined as nuclear, protein-coding genes that lack introns in their CDSs. They have been studied not only to determine their origin and ... -
Sleep Quality in Chilean Professional Soccer Players
(MDPI, 2021-06)Recent research has shown that good sleep quality has a positive effect on physical performance. However, sleep quality in Chilean professional soccer players is unknown. The purpose of this study was to determine sleep ... -
