Effortless learning during sleep is everybody’s dream. Several studies found that presenting odor cues during learning and selectively during slow wave sleep increases learning success.. ..We (1) performed a field study of vocabulary-learning in a regular school setting, (2) stimulated with odor cues during the whole night without sleep monitoring, and (3) applied the odor… Continue reading How #odor cues help to optimize #learning during sleep in a real life-setting
#Eating Jet Lag: A Marker of the Variability in Meal Timing and Its Association with #Body Mass Index
The timing of food intake has been associated with obesity and adverse metabolic outcomes, independently of the amount or content of food intake and activity level. However, the impact of the variability in the timing of food intake between weekends and weekdays on BMI (body mass index) remains unexplored. To address that, we propose to… Continue reading #Eating Jet Lag: A Marker of the Variability in Meal Timing and Its Association with #Body Mass Index
High-#protein diets increase #cardiovascular risk by activating macrophage mTOR to suppress mitophagy
High-protein diets are commonly utilized for weight loss, yet they have been reported to raise cardiovascular risk. The mechanisms underlying this risk are unknown. Here, we show that dietary protein drives atherosclerosis and lesion complexity. Protein ingestion acutely elevates amino acid levels in blood and atherosclerotic plaques, stimulating macrophage mammalian target of rapamycin (mTOR) signalling.… Continue reading High-#protein diets increase #cardiovascular risk by activating macrophage mTOR to suppress mitophagy
Effects of #Caffeine and Acute Aerobic #Exercise on Working Memory and Caffeine Withdrawal
Studies show that a single bout of exercise confers cognitive benefits. However, many individuals use psychoactive substances such as caffeine to enhance cognitive performance.. The objectives of this study were to compare the effects of acute moderate intensity aerobic exercise to caffeine on working memory (WM) and caffeine withdrawal symptoms (CWS). In Phase I, non-caffeine… Continue reading Effects of #Caffeine and Acute Aerobic #Exercise on Working Memory and Caffeine Withdrawal
Behavioral effects of multiple-dose #oxytocin treatment in #autism: a randomized, placebo-controlled trial with long-term follow-up
Intranasal administration of the “prosocial” neuropeptide oxytocin is increasingly explored as a potential treatment for targeting the core characteristics of autism spectrum disorder (ASD).. ..Among the secondary outcome measures, treatment-specific improvements were identified in the Repetitive Behavior Scale and State Adult Attachment Measure, indicating reductions in self-reported repetitive behaviors (p = .04) and reduced feelings… Continue reading Behavioral effects of multiple-dose #oxytocin treatment in #autism: a randomized, placebo-controlled trial with long-term follow-up

Five-Year Outcomes of Transcatheter or Surgical #Aortic-Valve Replacement
..At 5 years, there was no significant difference in the incidence of death from any cause or disabling stroke between the TAVR group and the surgery group (47.9% and 43.4%, respectively; hazard ratio, 1.09; 95% confidence interval [CI], 0.95 to 1.25; P=0.21). Results were similar for the transfemoral-access cohort (44.5% and 42.0%, respectively; hazard ratio,… Continue reading Five-Year Outcomes of Transcatheter or Surgical #Aortic-Valve Replacement
Temporal Changes in Resting #Heart Rate, Left Ventricular Dysfunction, Heart #Failure and Cardiovascular Disease: CARDIA Study
..Higher alcohol consumption (β=0.03, p<0.001), lower physical activity (β=0.002,p=001), smoking (β=1.58, p<0.001), men (p<0.001), African-Americans (p<0.001), impaired left ventricular relaxation (e´,β=-0.13, p=0.002), and worse diastolic function (E/e´,β=0.1, p=0.01) were associated with longitudinal increases in resting heart rate. We observed 268 cardiovascular disease and 74 heart failure events over a median of 26 years. In Cox… Continue reading Temporal Changes in Resting #Heart Rate, Left Ventricular Dysfunction, Heart #Failure and Cardiovascular Disease: CARDIA Study
Vitamin #B6 Addiction in Acute Myeloid #Leukemia
Cancer cells rely on altered metabolism to support abnormal proliferation. We performed a CRISPR/Cas9 functional genomic screen targeting metabolic enzymes and identified PDXK—an enzyme that produces pyridoxal phosphate (PLP) from vitamin B6—as an acute myeloid leukemia (AML)-selective dependency.. PDXK kinase activity is required for PLP production and AML cell proliferation, and pharmacological blockade of the… Continue reading Vitamin #B6 Addiction in Acute Myeloid #Leukemia
