Traditional lighting methods have environmental and efficiency drawbacks. These methods are gradually being overshadowed by light-emitting diodes (LEDs) because of their superior color rendering and energy efficiency. In this study, color-tunable NaBa(Ba/Sr/Ca)SiOF:Eu phosphors are successfully designed by modulating the local crystal field environment through homodominant-group cation substitution, thereby allowing for a spectral shift from blue to bright cyan.

Cerebral blood flow (CBF) dysfunction is an essential feature of AD, and the liver plays an important role in the pathogenesis of dementia. However, the associations of APOE4 with CBF and liver function markers in patients with cognitive impairment remains unclear.

Herein, we established a paradigm to achieve novel silicate BaYSiO (BYSO):Ce,Tb. The near-ultraviolet light efficiently excites the BYSO:Ce material, causing it to emit light at a wavelength of 408 nm.

However, the relevance of liver function alterations to cerebral blood flow (CBF) of patients with AD remains unclear.
Objective: We aimed to investigate the associations between liver function changes and CBF of patients with AD.
LncRNA MIR31HG is involved in many types of cancers, while its roles in breast cancer are still unknown. The current study aimed to explore the function of lncRNA MIR31HG in breast cancer and the underlying mechanisms. Stable expression cell lines were constructed by using lentivirus particles.

Thus, in this study, in addition to the effect of VIRMA on TNBC, the underlying mechanisms were also explored.
Methods: , VIRMA expression was detected by quantitative real-time polymerase chain reaction (qRT-PCR) and western blot; VIRMA lentiviral overexpression vector (LV-VIRMA) and lentiviral vector connected with the shRNA targeting VIRMA (LV-shVIRMA) were constructed to explore the functional role of VIRMA; RNA immunoprecipitation and qRT-PCR were performed to assess the relationship between VIRMA and kinesin family 15 (KIF15).
Objectives: To investigate the most discussed topics and possible new interests in dental implants among the public, as well as the public sentiments toward dental implants through topic and sentiment analysis of online comments.
Methods: Comments of the top 100 most viewed dental implant-related YouTube videos were studied. The comments were analyzed by topic analysis (LDA topic model, Word co-occurrence analysis) and sentiment analysis.
Using a meta-analysis approach, we conducted a comprehensive evaluation of the effect of neoadjuvant chemotherapy (NACT) on the incidence of surgical site wound infection during immediate breast reconstruction (IBR) following breast cancer. The aim was to provide evidence-based support for the prevention of wound surgical site infection during IBR after breast cancer surgery. Relevant literature on the effects of NACT on IBR in patients with breast cancer published up until May 2023, was retrieved from various databases, including PubMed, Cochrane Library, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang databases, and China Biology Medicine Database.

However, it remains unclear whether there is any relationship between lower liver function and cognitive impairment among the elderly.
Methods: From 2017 to 2018, we recruited 7,201 older people (over 60 years old) from 51 community health centers in the Luohu District of Shenzhen City.
Vocal learning is thought to have evolved in 3 orders of birds (songbirds, parrots, and hummingbirds), with each showing similar brain regions that have comparable gene expression specializations relative to the surrounding forebrain motor circuitry. Here, we searched for signatures of these same gene expression specializations in previously uncharacterized brains of 7 assumed vocal non-learning bird lineages across the early branches of the avian family tree. Our findings using a conserved marker for the song system found little evidence of specializations in these taxa, except for woodpeckers.

Materials And Methods: Cohort studies demonstrating the association between T/Gly index measured at the first trimester or before pregnancy and the subsequent incidence of GDM were identified by search of PubMed, Embase, China National Knowledge Infrastructure, and WanFang databases. A random-effect model incorporating the heterogeneity was applied to pool the results.
Background: Periodontitis is associated with the pathogenesis of atherosclerotic plaque, and hypersensitive C reactive protein (hs-CRP) and lipoprotein-associated phospholipase A2 (Lp-PLA2) are the serum biomarkers of the stability of atherosclerotic plaque. Whether periodontitis is associated with the serum level of hs-CRP and Lp-PLA2 of acute ischemic stroke remains unclear.
