P300 component of the event related potential (ERP) provides one neurophysiological index of cognitive dysfunction in depression. Forty subjects fulfilling DSM-III criteria for depression were compared to 40 age and sex matched normal controls. The P300 was recorded using the auditory odd-ball paradigm. Depressives had a significantly prolonged P300 latency and reduced P300 amplitude as compared to the controls. The P300 latency showed a significant positive correlation with age of the patient and severity of depression while P300 amplitude showed a significant negative correlation with age. The clinical subcategory of depression, duration of illness and sex did not show any relationship with P300 abnormality. Twelve out of 40 depressives (30%) had an abnormal P300. The mean Hamilton Rating Scale for Depression (HRSD) score was significantly high in those with an abnormal P300.

Background: Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are remarkably effective for treating EGFR-mutant non-small cell lung cancer (NSCLC). However, patients inevitably develop acquired drug resistance, resulting in recurrence or metastasis. It is important to identify novel effective therapeutic targets to reverse acquired TKI resistance.

Maternal exposure to a Western-type diet (WD) increases the susceptibility of adult offspring to atherosclerosis, partly because fetal endothelial cells (ECs) become dysfunctional and inflamed due to risk factors transmitted via maternal-fetal blood exchange. However, the underlying mechanisms remain unclear. Here we show that maternal WD accelerates atherogenesis in adult offspring mice by regulating chromatin dynamics through activator protein-1 (AP-1) in aortic ECs, inducing inflammatory memory at the chromatin level.

The continued influence effect of misinformation (CIE) occurs when misinformation affects memory and decision making even after correction. Here, we examined the neurocognitive processes underlying the correction and subsequent veracity judgements of misinformation. Employing electroencephalography (EEG), we examined event-related potentials (ERPs): the P300 during encoding of corrections, and the P300 and FN400 during subsequent veracity judgement.

Histone lysine succinylation, an emerging epigenetic marker, has been implicated in diverse cellular functions, yet its role in cancer drug resistance is not well understood. Here we investigated the genome-wide alterations in histone 3 lysine 23 succinylation (H3K23su) and its impact on gene expression in 5-fluorouracil (5-FU)-resistant HCT15 colon cancer cells. We utilized CUT&Tag assays to identify differentially enriched regions (DERs) of H3K23su in 5-FU-resistant HCT15 cells via integration with ATAC-seq and RNA sequencing data.

Background: Obesity is the most significant risk factor associated with primary hypertension. A high-fat diet may lead to obesity-related hypertension, with evidence indicating that individuals with this condition exhibit a diminished adenosine 3',5'-cyclic monophosphate (cAMP) signaling pathway, although the exact mechanisms remain unclear. This study aimed to investigate the regulatory role of the cAMP signaling pathway in obesity-related hypertension.
