Target identification is crucial for drug screening and development because it can reveal the mechanism of drug action and ensure the reliability and accuracy of the results. Chemical biology, an interdisciplinary field combining chemistry and biology, can assist in this process by studying the interactions between active molecular compounds and proteins and their physiological effects. It can also help predict potential drug targets or candidates, develop new biomarker assays and diagnostic reagents, and evaluate the selectivity and range of active compounds to reduce the risk of off-target effects.

In a preclinical rodent model of CHIP-related ataxia, we observed that CHIP mutations lead to increased levels of phosphodiesterase 9A (PDE9A), whose role in this context remains poorly understood. Here, we investigated the molecular mechanisms underlying the role of PDE9A in CHIP-related ataxia and demonstrated that CHIP binds to PDE9A, facilitating its polyubiquitination and autophagic degradation.

Repressor element-1 silencing transcription factor (REST) is a major regulator of oligodendrocyte differentiation, and the role of REST on DM remyelination remains to be investigated. Here, we investigated the effects of REST and DNA methylation on DM remyelination and explored the underlying mechanisms.

However, postoperative urinary tract infections (UTIs) are common and challenging. This retrospective cohort study aimed to identify UTI risk factors following an operation for paediatric hydronephrosis.

SERINE-RICH ENDOGENOUS PEPTIDEs (SCOOPs) mediate the complex formation of Arabidopsis RK MIK2 and co-receptor BAK1, triggering immune responses. Through structural, biochemical and genetic analyses, we demonstrate that SCOOPs use their SxS motif and adjacent residues to bind MIK2 and the carboxy-terminal GGR residues to link MIK2 to BAK1.

Methods: All studies that assessed the efficacy of MAO-B inhibitors in patients with early PD were searched. Publications were screened, and data were extracted according to predefined criteria.
Late-onset Pompe disease (LOPD) is caused by a genetic deficiency of the lysosomal enzyme acid alpha-glucosidase (GAA), leading to progressive limb-girdle weakness and respiratory impairment. The insidious onset of non-specific early symptoms often prohibits timely diagnosis. This study aimed to validate the high-risk screening criteria for LOPD in the Chinese population.

The aging global demographic and increased life expectancy have led to a rapid surge in PD cases, imposing a significant societal burden. PD along with other neurodegenerative diseases has garnered increasing attention from the scientific community.

Screw insertion torque is an objective index for evaluating screw-bone structural stability. Therefore, accurate prediction of screw insertion torque can improve the preoperative evaluation of patients, optimize the surgical plan, and improve the surgical effect.

Owing to the potential carbon emission in the preparation process of WEGs, whether WEG represents a clean electricity generation technology is open to question. Here, a brand-new strategy is proposed for manufacturing negative carbon emission WEG (CWEG).

There has been a gradual increase in the number of reported cases in recent years, with high morbidity and mortality rates. The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling pathway plays an important role in the innate immune defense activated by viral infection; however, the role of the cGAS-STING signaling pathway during SFTSV infection is still unclear.

As such, given the inconclusive results of extensive research on the association between IBD and PD, our study intends to examine this relationship further using the UK Biobank database.
Methods: We conducted a prospective cohort study using the Cox proportional hazards model, analyzing data from the UK Biobank to investigate the relationship between IBD and PD, following subjects until PD diagnosis, loss to follow up, death or study termination on 30 June, 2023.
Diabetes has been associated with an elevated risk of Parkinson's disease (PD), yet the relationship between prediabetes (PreD) and the incidence of PD in the adult population remains unclear. Therefore, a systematic review and meta-analysis was conducted to evaluate if PreD is also associated with a higher risk of PD. We conducted comprehensive searches of the PubMed, Embase, and Web of Science databases to identify relevant observational studies with longitudinal follow-up.

Objective: The coronavirus disease 2019 (COVID-19) is an acute respiratory infectious disease caused by the SARA-CoV-2, characterized by high infectivity and incidence. Clinical data indicates that COVID-19 significantly damages patients' perception, motor function, and cognitive function. However, the electrophysiological mechanism by which the disease affects the patient's nervous system is not yet clear.

Syllable frequency effects in spoken word production have been interpreted as evidence that speakers store syllable-sized motor programmes for phonetic encoding in alphabetic languages such as English or Dutch. However, the cognitive mechanism underlying the syllable frequency effect in Chinese spoken word production remains unknown. To investigate the locus of the syllable frequency effect in spoken Chinese, this study used a picture-word interference (PWI) task in which participants were asked to name the picture while ignoring the distractor word.

Methods: All patients diagnosed with clinical suspicion of SI were enrolled, and data were collected through a retrospective chart review of patient records. Biopsy specimens obtained from each patient were tested via mNGS and microbial culture.
Enterovirus D68 (EV-D68) can cause respiratory diseases and acute flaccid paralysis, posing a great threat to public health. Interferons are cytokines secreted by host cells that have broad-spectrum antiviral effects, inducing the expression of hundreds of interferon-stimulated genes (ISGs). EV-D68 activates ISG expression early in infection, but at a later stage, the virus suppresses ISG expression, a strategy evolved by EV-D68 to antagonize interferons.

Participants were asked to produce sentences with simple or complex initial phrase structures (IPS) in Experiment 1 while producing individual words in Experiment 2. Young and older speakers showed comparable speaking latencies in sentence production task, whereas older speakers showed longer latencies than young speakers in word production task.
