Boosting Brain Health: Interventions for the Prevention and Treatment of Mild Cognitive Impairment and Early Neurodegenerative Disease.

Mild Cognitive Impairment (MCI) and dementia are becoming more common with an aging population, and the numbers are expected to rise. These conditions can have a significant impact on patients, family, and health care systems. Lifestyle changes including physical activity, nutrition, quality sleep, socialization, cognitive activity and mental stimulation, routine medical care, and mental health care have the potential to prevent cognitive and functional decline and optimize daily living in all individuals, including those with MCI and early neurodegenerative disease.

Effects of access condition on substance use disorder-like phenotypes in male and female rats self-administering MDPV or cocaine.

Substance use disorder (SUD) is a heterogeneous disorder, where severity, symptoms, and patterns of use vary across individuals. Yet, when rats self-administer cocaine under short-access conditions, their behavior tends to be well-regulated, though individual differences can emerge with long- or intermittent-access. In contrast, significant individual differences emerge when rats self-administer 3,4-methylenedioxypyrovalerone (MDPV), even under short-access conditions, wherein ~30 % of rats exhibit high levels of drug-taking.

Effects of access condition on substance use disorder-like phenotypes in male and female rats self-administering MDPV or cocaine.

Substance use disorder (SUD) is a heterogeneous disorder, where severity, symptoms, and patterns of substance use vary across individuals. Yet, when rats are allowed to self-administer drugs such as cocaine under short-access conditions, their behavior tends to be well-regulated and homogeneous in nature; though individual differences can emerge when rats are provided long- or intermittent-access to cocaine. In contrast to cocaine, significant individual differences emerge when rats are allowed to self-administer 3,4-methylenedioxypyrovalerone (MDPV), even under short-access conditions, wherein ~30% of rats rapidly transition to high levels of drug-taking.

International Association for the Study of Pain publications over the 50-year span.

The International Association for the Study of Pain (IASP) has a 50-year history of publishing educational and research materials, ranging from traditional print format books, journals, and other informational formats to online and electronic formats. Here we provide a historical overview of IASP publications and reflections from the perspective of 5 former or current Editors-in-Chief.

Biochemical and behavioral effects of decreasing dietary linoleic acid and increasing eicosapentaenoic acid and docosahexaenoic acid in a rat chronic monoarthrits model.

Clinical studies have demonstrated that decreasing linoleic acid (LA) while increasing eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in diets evokes an analgesic effect in headache sufferers. We utilized a rat chronic monoarthritis model to determine if these analgesic effects can be reproduced in rats and to and further probe potential analgesic mechanisms. We fed 8 rats a control diet (with fatty acid levels similar to standard US diets) and 8 rats a low LA diet with added EPA and DHA (H3L6 diet) and after 10 weeks, performed a unilateral intraarticular injection of Complete's Freund Adjuvant (CFA).
