In the rapidly evolving field of personalized news recommendation, capturing and effectively utilizing user interests remains a significant challenge due to the vast diversity and dynamic nature of user interactions with news content. Existing recommendation models often fail to fully integrate candidate news items into user interest modeling, which can result in suboptimal recommendation accuracy and relevance. This limitation stems from their insufficient ability to jointly consider user history and the characteristics of candidate news items in the modeling process.

We aimed to provide a comprehensive variants profile of the ATXN1, ATXN2, and ATXN3 genes and examine the association of these variants with the risk and clinical characteristics of ALS. We screened and analyzed the rare variants in a cohort of 2220 ALS patients from Southwest China, using controls from the Genome Aggregation Database (gnomAD) and the China Metabolic Analytics Project (ChinaMAP).

Objective: To summarize the terms and definitions related to neurofibromatosis type 1 (NF1) with a view to standardizing and unifying the existing terminology system.
Methods: To review the research literature related to NF1 at home and abroad, and to summarize the expressions of the disease and related terms.
Results: There are still some limitations in the current knowledge of NF1, especially in the expression of the terminology, and there are discrepancies in the description and naming of NF1-related features in different medical literatures and clinical guides.
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by motor neuron degeneration. Dysregulation of long non-coding RNAs (lncRNAs) has been implicated in ALS pathogenesis but their roles remain unclear. Previous studies found lnc-ABCA12-3 was downregulated in ALS patients.

Methods: Utilizing data from the United Kingdom Biobank, we investigated the relationship between baseline levels of serum and urine albumin and the occurrence of common NDDs, including Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS) and dementia, employing Cox proportional hazards regression analysis.
Plexiform neurofibromas (PNFs) are a prevalent and severe phenotype associated with NF1, characterized by a high teratogenic rate and potential for malignant transformation. The growth and recurrence of PNFs are attributed to aberrant proliferation and migration of Nf1-deficient Schwann cells. Protein tyrosine phosphatase receptor S (PTPRS) is believed to modulate cell migration and invasion by inhibiting the EMT process in NF1-derived malignant peripheral nerve sheath tumors.

We sought to identify key genes modulating chronic pain risk by regulating brain protein expression. We integrated brain proteomic data with the largest genome-wide dataset for multisite chronic pain (N = 387,649) in a proteome-wide association study (PWAS) using discovery and confirmatory proteomic datasets (N = 376 and 152) from the dorsolateral prefrontal cortex.

Nevertheless, the influence of genetic variants in genes regulating DNA methylation on ALS patients is not well understood. Therefore, we aim to provide a comprehensive variant profile of genes related to DNA methylation (DNMT1, DNMT3A, DNMT3B, DNMT3L) and demethylation (TET1, TET2, TET3, TDG) and to investigate the association of these variants with ALS.

Methods: In order to investigate the potential causal association between AD and prevalent oral diseases, we conducted a bi-directional two-sample Mendelian randomization analysis based on summary statistics from genome-wide association studies of AD ( = 63,926), as well as mouth ulcer ( = 461,103), oral cavity cancer ( = 4,151), and periodontal disease ( = 527,652).
Background: The calcium channel has been considered to have great potential as a drug target for neuroprotective therapy in Parkinson's disease (PD), but previous studies yielded inconsistent results.
Objectives: This study aimed to conduct a systematic review and meta-analysis to assess the relationship between using calcium channel blockers (CCBs) and the risk and progression of PD.
Data Sources And Methods: The terms such as 'Parkinson's disease', 'PD', 'calcium channel blockers', and 'CCB' were used to search the literature published before 1 May 2023 in English databases, including PubMed, Embase, and Cochrane Library, for studies on CCB and PD.
Background: Alzheimer's disease (AD) is on the rise in our aging society, making it crucial to identify additional risk factors to mitigate its increasing incidence. This systematic review and meta-analysis aimed to provide updated evidence regarding the association between sleep and AD.
Methods: We conducted a comprehensive search of MEDLINE, EMBASE, and Web of Science databases from inception to July 2023 to identify longitudinal studies.
The prevalence of Alzheimer's disease (AD) is increasing as the population ages, and patients with AD have a poor prognosis. However, knowledge on factors for predicting the survival of AD remains sparse. Here, we aimed to systematically explore predictors of AD survival.

Numerous studies demonstrate abnormally elevated and active p53 in the central nervous system of ALS patients. Activation of p53-regulated pro-apoptotic signaling pathways may trigger motor neuron death.

In this study, we have designed, synthesized and tested three series of novel dihydropteridone derivatives possessing isoindolin-1-one or isoindoline moieties as potent inhibitors of PLK1/BRD4. Remarkably, most of the compounds showed preferable inhibitory activity against PLK1 and BRD4. Compound SC10 exhibited excellent inhibitory activity with IC values of 0.

To address this challenge, we developed a smart theranostic prodrug system that combines a fluorophore and an anticancer drug, specifically 6-diazo-5-oxo-l-norleucine (DON), using a thioketal linkage (TK). This system enables imaging, chemotherapy, photodynamic therapy, and on-demand drug release upon radiation exposure.
