Association of low-carbohydrate diet score and carbohydrate quality index with colorectal cancer risk: a large-scale case-control study.

Purpose: Carbohydrate intake has been linked to colorectal cancer (CRC) risk, with variations depending on the quantity and quality of carbohydrates consumed. This study aimed to investigate the association between carbohydrate quantity and quality, using the low-carbohydrate diet score (LCD) and carbohydrate quality index (CQI), and the risk of CRC in the Chinese population.

Methods: We conducted a case-control study in Guangzhou, China, with 2,799 CRC cases and an equal number of sex- and age-matched controls.

[Effect of post-annealing on the structure and fluorescence properties of YMnO3 thin films].

YMnO3 thin films deposited on Si (100) substrate by pulsed laser deposition at room temperature were annealed at different temperatures. The microstructure and fluorescent emission properties of these films were studied using XRD and UV-Vis spectroscopy. The results show that polycrystalline YMnO3 thin films can be obtained through post-annealing, in which hexagonal phase and orthorhombic phase coexist.
