Background: Children with attention deficit hyperactivity disorder (ADHD) have a delayed development. Two main cognitive models of ADHD are executive (cold) and motivational (hot) models. In this study, we aimed to compare the development of hot and cold executive functions in children with and without ADHD.
Methods And Procedures: Forty-six children with ADHD symptoms (56% boys) and forty-four typically developing controls (54% boys), in three age groups of 6-8, 8-10 and 10-12 years, were participated in the study. Go/No-Go Task (GNGT), One-Back Test (OBT) and Shifting Attention Test (SAT), Delay Discounting Test (DDT) and Balloon Analogue Risk Task (BART) were used for assessment.
Outcomes And Results: Children with ADHD showed lower performance in GNG, OBT, SAT, and BART, but intact performance in DDT. The tasks' performance was significantly different between three age groups in GNG and SAT, but similar in OBT and BART. The interaction effect was significant only for the BART measures.
Conclusions And Implications: Children with ADHD compared to typically developing children, experience impaired hot and cold executive functions. The cognitive delay was found only in risky decision making as a hot executive function.

Colorectal cancer (CRC) is one of the most prevalent and deadly malignancies worldwide. Recently, ferroptosis, a novel form of regulated cell death characterized by iron dependency and lipid peroxidation, has garnered significant attention from researchers. The mechanisms underlying ferroptosis, including intracellular iron levels, lipid peroxidation, and antioxidant system regulation, offer new insights into cancer treatment strategies.

The study of transient and variable events, including novae, active galactic nuclei, and black hole binaries, has historically been a fruitful path for elucidating the evolutionary mechanisms of our universe. The study of such events in the millimeter and submillimeter is, however, still in its infancy. Submillimeter observations probe a variety of materials, such as optically thick dust, which are hard to study in other wavelengths.

Given the rising frequency of thermal extremes (heatwaves and cold snaps) due to climate change, comprehending how a plant's origin affects its thermal tolerance breadth (TTB) becomes vital. We studied juvenile plants from three biomes: temperate coastal rainforest, desert and alpine. In controlled settings, plants underwent hot days and cold nights in a factorial design to examine thermal tolerance acclimation.

Background: Kuwait, one of the world's hottest countries, faces increasing temperatures due to climate change. With a large migrant population predominantly employed in physically demanding jobs, the exact effects and burdens of temperature exposure on cardiovascular risk among this population remain unknown. This study aimed to investigate the relationship between temperature and myocardial infarction (MI) risk among migrants in Kuwait.

Increasing evidence has shown that physical exercise remarkably inhibits oncogenesis and progression of numerous cancers and exercise-responsive microRNAs (miRNAs) exert a marked role in exercise-mediated tumor suppression. In this research, expression and prognostic values of exercise-responsive miRNAs were examined in breast cancer (BRCA) and further pan-cancer types. In addition, multiple independent public and in-house cohorts, in vitro assays involving multiple, macrophages, fibroblasts, and tumor cells, and in vivo models were utilized to uncover the tumor-suppressive roles of miR-29a-3p in cancers.
