It is well known that there are different preferences in correlated color temperature of light sources for daily living activities or for viewing artistic paintings. There are also data relating the capacity of observers to make judgments on color differences with the spectral power distribution of the light source used. The present work describes a visual color discrimination experiment whose results confirm the existence of a relationship between the correlated color temperature of a light source and the color discrimination capacities of the observers.

Yellow seed coat color (SCC) is a valuable trait in , which is significantly correlated to high seed oil content (SOC) and low seed lignocellulose content (SLC). However, no dominant yellow SCC genes were identified in . In this study, a dominant yellow SCC N53-2 was verified, and then 58,981 eQTLs and 25 trans-eQTL hotspots were identified in a double haploid population derived from N53-2 and black SCC material Ken-C8.

Background: The immunoproteasome (IP) is the inducible form of the constitutive 20S proteasome upregulated in immune cells. The IP consists of 3 inducible β subunits (β1i - LMP2, β2i - MECL1, and β5i - LMP7), which generate MHC-I compatible peptides. IPs are induced by pro-inflammatory cytokine signaling, as well as oxidative stress signaling.

Background: Gait performance has been found to be an effective method for screening cognitive impairment in elderly. Nevertheless, the efficacy of utilizing gait speed as a marker for monitoring cognitive changes remains incompletely substantiated.
Method: From 2021 to 2023, we recruited 104 participants from the memory clinic of Cardinal Tien Hospital in Taipei, Taiwan.

Background: The effect of amyloid-b brain deposition on cognition is still debated, since it has been shown that its accumulation begins almost 15 years before cognitive symptoms' onset, then reaches a plateau while cognition continues to decline. We studied if there is a parallel between amyloid-b deposition and cognitive performances in young-onset Mild Cognitive Impairment (MCI) patients, and if it is associated to symptoms' duration.
Method: Subjects with a diagnosis of MCI and symptoms' onset ≤ 65 years underwent neuropsychological assessment, Magnetic Resonance Imaging, and (F)Flutemetamol-PET (amy-PET).

Background: Elderly people, especially those with mild cognitive impairment (MCI), are at heightened risk of developing dementia. In this study, we examined how well healthy young, normally aging and MCI participants performed in visual short-term memory (VSTM) binding, a cognitive process in which an item's different visual properties (e.g.
