Childhood cancer and its treatment puts survivors at risk of low working memory capacity. Working memory represents a core cognitive function, which is crucial in daily life and academic tasks. The aim of this functional MRI (fMRI) study was to examine the working memory network of survivors of childhood cancer without central nervous system (CNS) involvement and its relation to cognitive performance. Thirty survivors (aged 7-16 years, ≥ 1 year after cancer treatment) and 30 healthy controls performed a visuospatial working memory task during MRI, including a low- and a high-demand condition. Working memory performance was assessed using standardized tests outside the scanner. When cognitive demands increased, survivors performed worse than controls and showed evidence for slightly atypical working memory-related activation. The survivor group exhibited hyperactivation in the right-hemispheric superior parietal lobe (SPL) in the high- compared to the low-demand working memory condition, while maintaining their performance levels. Hyperactivation in the right SPL coincided with poorer working memory performance outside the scanner in survivors. fMRI: Functional magnetic resonance imaging; CNS: Central nervous system; MNI: Montreal Neurological Institute; SES: Socioeconomic status; SPL: Superior parietal lobe.

Visual search relies on the ability to use information about the target in working memory to guide attention and make target-match decisions. The 'attentional' or 'target' template is thought to be encoded within an inferior frontal junction (IFJ)-visual attentional network. While this template typically contains veridical target features, behavioral studies have shown that target-associated information, such as statistically co-occurring object pairs, can also guide attention.

Recent studies showed that the presence of the experimenter hinders executive functions. Belletier and Camos (2018) extended these findings to working memory, reporting a detrimental effect of the experimenter presence only when participants performed an aloud concurrent articulation during maintenance. Under such a condition, participants likely relied on an attentional maintenance mechanism rather that an articulatory mechanism, supporting the account of a capture of attention by the social presence.

Dengue virus remains a significant global health threat, imposing a substantial disease burden on nearly half of the world's population. The urgent need for effective antiviral therapeutics, including therapeutic peptides targeting the Dengue virus, is critical in the current healthcare landscape. However, the availability of anti-Dengue peptides (ADPs) data remains limited in existing data sets, posing a challenge for computational modeling and discovery.

Background: Obesity and hypertension are widespread health issues associated with changes in brain structure and cognitive function, especially in individuals who lead sedentary lifestyles. This research examines the connections between obesity, high blood pressure, brain structure, and cognitive abilities in people who lead a sedentary lifestyle.
Materials And Methods: The study involved 90 individuals aged between 18 and 35 years, who were categorized into three groups: control (n = 30), obese (n = 30), and hypertensive (n = 30).
