Background: Although the use of brain health dietary supplements (brain DS) has increased, there is limited research on safety and risk of these products. Brain DS may be beneficial for improving memory, concentration, and focus but may also carry risks.
Objectives: To assess brain DS users' utilization experiences and identify factors associated with likelihood of brain DS use among nonusers.
Design: An internet-based cross-sectional survey study was conducted using a sample of middle-aged US adults. Respondents' sociodemographic characteristics and health beliefs regarding brain DS were collected. Brain DS users' utilization experiences such as negative side effects and spending were also collected.
Participants And Setting: Purposive sampling was utilized for users and nonusers sample recruitment.
Main Outcome Measures: Brain DS users' utilization experience and future likelihood of brain DS use among nonusers.
Statistical Analyses Performed: Descriptive statistics on brain DS users' utilization experiences were reported. Ordinal logistic regression with sociodemographic and belief characteristics as predictors was employed to identify factors associated with the likelihood of brain DS among nonusers.
Results: Five hundred twenty-five respondents (mean age = 43.8 ± 9.2 years) completed the survey. Among 260 users, primary reasons for use were enhancing memory (n = 136) and helping concentration and focus (n = 108). During the past year, 40% spent $50 to $200 (range = $0 to >$1,000) and 37% reported experiencing negative side effects. Among 265 nonusers, being female (odds ratio 2.04, 95% CI 1.21 to 3.45), perceived susceptibility to brain problems (odds ratio 1.90, 95% CI 1.28 to 2.83), recommendation from others (odds ratio 1.55, 95% CI 1.03 to 2.35) and perceived benefits of brain DS (odds ratio 2.82, 95% CI 1.60 to 4.96) were significantly associated with increased likelihood of future brain DS use.
Conclusions: Individual spending on brain DS varies and about 40% of users reported experiencing negative side effects. As individuals primarily rely on healthcare providers for recommendations, health care providers should be prepared to engage in discussions about brain DS with patients.

Background: Peripheral nerve sheath tumors (PNSTs) encompass entities with different cellular differentiation and degrees of malignancy. Spatial heterogeneity complicates diagnosis and grading of PNSTs in some cases. In malignant PNST (MPNST) for example, single cell sequencing data has shown dissimilar differentiation states of tumor cells.

Research on memristive devices to seamlessly integrate and replicate the dynamic behaviors of biological synapses will illuminate the mechanisms underlying parallel processing and information storage in the human brain, thereby affording novel insights for the advancement of artificial intelligence. Here, an artificial electric synapse is demonstrated on a one-step Mo-selenized MoSe memristor, having not only long-term stable resistive switching characteristics (reset 0.51 ± 0.

To regulate brain function, peripheral compounds must traverse the blood-brain barrier (BBB), an interface between the brain and the circulatory system. To determine whether specific transport mechanisms are relevant for sleep, we conducted a BBB-specific inducible RNAi knockdown (iKD) screen for genes affecting sleep in . We observed reduced sleep with knockdown of solute carrier , a carnitine transporter, as determined by isotope flux.

Sleep need accumulates during waking and dissipates during sleep to maintain sleep homeostasis (process S). Besides the regulation of daily (baseline) sleep amount, homeostatic sleep regulation commonly refers to the universal phenomenon that sleep deprivation (SD) causes an increase of sleep need, hence, the amount and intensity of subsequent recovery sleep. The central regulators and signaling pathways that govern the baseline and homeostatic sleep regulations in mammals remain unclear.
