Weight Reduction Interventions Using Digital Health for Employees with Obesity: A Systematic Review.

Purpose: This study aimed to systematically review the literature on randomized controlled trials on weight reduction interventions using digital health for employees with obesity.

Methods: All relevant articles published until September 2021 were systematically identified from six electronic databases: MEDLINE, EMBASE, CINAHL, PsycINFO, RISS, and KISS. Data selection and extraction were independently performed by three researchers.

Demographic and Clinical Factors Associated With Anti-SARS-CoV-2 Antibody Levels After 2 BNT162b2 mRNA Vaccine Doses.

Importance: The factors associated with long-term serum levels of anti-SARS-CoV-2 antibodies after COVID-19 vaccination in healthy individuals have rarely been investigated.

Objective: To investigate factors associated with anti-SARS-CoV-2 antibody levels.

Design, Setting, And Participants: This prospective cohort study included health care workers at Kyungpook National University Chilgok Hospital (Daegu, Korea) with no history of SARS-CoV-2 infection who received 2 doses of the BNT162b2 mRNA COVID-19 vaccine (Pfizer/BioNTech; first dose, March 17-20, 2021; second dose, April 7-10, 2021).

Dopamine D2 receptor-mediated circuit from the central amygdala to the bed nucleus of the stria terminalis regulates impulsive behavior.

Impulsivity is closely associated with addictive disorders, and changes in the brain dopamine system have been proposed to affect impulse control in reward-related behaviors. However, the central neural pathways through which the dopamine system controls impulsive behavior are still unclear. We found that the absence of the D2 dopamine receptor (D2R) increased impulsive behavior in mice, whereas restoration of D2R expression specifically in the central amygdala (CeA) of D2R knockout mice ( normalized their enhanced impulsivity.

Temperature variable luminescence and color tuning of Eu2+/Mn2+-codoped strontium magnesium phosphates as promising red-emitting phosphors for light emitting diodes.

Eu(2+) and Mn(2+) codoped violet-/red-emitting strontium magnesium phosphates, SrMgP2O7, SrMg2P2O8 and Sr2Mg3P4O15, were prepared and their emission properties, especially for color tuning with temperature variable luminescence, were investigated. Simply by changing the host composition of the SrO-MgO-P2O5 ternary system, we can control the Eu(2+)-sensitized Mn(2+) emission efficiency as well as the thermal quenching of incorporated activators. We can realize that the overall luminescence behavior is induced by the Mn(2+) center positioned at different coordination states with intermixed Sr(2+)/Mg(2+) sites in various hosts, which resulted in widely tunable colors from violet-red through orange-red to pure red.
