Effectiveness of intermittent cash incentives to increase step counts.

Only 25% of adults meet both aerobic and strength training recommendations for physical activity. Contingency management interventions have been used to increase physical activity; however, they may be cost prohibitive. Intermittently provided incentives lower costs and are effective for various health behaviors.

Escalating schedules of incentives increase physical activity with no differences between deposit and no-deposit groups: A systematic replication.

Physical inactivity has increasingly affected public health in the United States during the COVID-19 pandemic as it is associated with chronic diseases such as arthritis, cancer, and heart disease. Contingency management has been shown to increase physical activity. Therefore, the present study sought to evaluate the effects of an escalating schedule of monetary reinforcement with a reset contingency on physical activity, as compared between 2 counterbalanced groups in which a monetary deposit of $25 was either required (deposit group) or not (no-deposit group).

In vitro and in vivo inhibition of malaria parasite infection by monoclonal antibodies against Plasmodium falciparum circumsporozoite protein (CSP).

Plasmodium falciparum malaria contributes to a significant global disease burden. Circumsporozoite protein (CSP), the most abundant sporozoite stage antigen, is a prime vaccine candidate. Inhibitory monoclonal antibodies (mAbs) against CSP map to either a short junctional sequence or the central (NPNA) repeat region.
