Article Abstract
Our ability to maintain visuo-spatial information increases gradually through childhood and is highly variable across individuals, although the cognitive and neural mechanisms underpinning these differences in capacity are unknown. We presented participants with arrays of to-be-remembered items containing two targets, four targets, or two targets and two distracters. The participants were divided into three groups: (i) high-capacity adults; (ii) low-capacity adults; and (iii) typically developing children. In addition to our behavioral methods we used electrophysiological scalp recordings to contrast the immature VSTM capacity of the children with the deficient VSTM capacity of the low-capacity adults. We also observed a relative negativity in the maintenance delay, over scalp contralateral to the original locations of the memoranda. For the low-capacity adults, this negativity was similarly modulated by target and distracter items, indicative of poor selectivity. This was not the case for the high-capacity adults; the response to memory arrays containing two target items and two distracters was equivalent to the response elicited by arrays containing only two target items. Importantly, the pattern of results in the children's ERP data was equivalent to that of the high-capacity adults, rather than to the performance-matched low-capacity adults. In short, despite their obvious differences in capacity, children are not specifically impaired at filtering out distractors, as characteristic of low-capacity adults.

Lung cancer has the highest mortality rates worldwide, and Human Papillomavirus (HPV) has been associated with its carcinogenesis. In this study, HPV16 genes' expressions were investigated in patient samples, along with the immunological response promoted by lymphocytes and monocytes in A549 cells transfected with HPV oncogenes and co-cultured with PBMC. An increase in the expression of E5 was observed in the patients' samples.
Based on the Interaction of Person-Affect-Cognition-Execution model and the risk-buffering model, the current study explored how and when rumination increases problematic mobile phone use (PMPU) among Chinese female freshmen. Specifically, we investigated the underlying mechanism of PMPU by testing a moderated mediation model in which solitude capacity moderated the mediating role of fear of missing out (FoMO) in the relationship between rumination and PMPU. A sample of 1,389 female freshmen in China, with a mean age of 19.
Tubular adenomas (TA) are the most frequent of all colorectal adenomas. Current definitions of TA do not include the phenotype of the dysplastic crypts. We report a novel crypt phenotype characterized by dysplastic crypts with lateral buddings (DCLB).

Recent event-related potential (ERP) studies showed that individuals with low visual working memory (VWM) capacity are more susceptible to salience-driven attentional capture than high-capacity individuals are, with the latter being able to proactively suppress salient but irrelevant distractors. However, it remains unclear whether and how contingent attentional capture by distractors that possess a task-relevant (target) feature is related to VWM capacity. Here, we adopted a central focused-attention task that contained peripheral target-matching distractors to investigate this issue ( = 51 adults).
Sarcopenia screening tools have a low capacity to predict adverse outcomes that are consequences of sarcopenia in the elderly population. This study aimed to evaluate the ability of a new sarcopenia screening tool SARC-GLOBAL to predict negative clinical outcomes in the elderly. A total of 395 individuals were evaluated in a 42-month period.
