McAllister, C., Navani, D. JoVE Monthly Highlights: January 2018. J. Vis. Exp. (132), e6020, (2018).
Here's a look at what is featured in the January 2018 issue of JoVE: The World's Premier Video Journal.
This month, JoVE Behavior really grabs our attention with a novel protocol to analyze reaching and grasping movements. Here, our authors used frame-by-frame video to study healthy adult subjects as they reach for a donut hole on a pedestal. This technique allows researchers to study these movements without specialized or expensive equipment.
From studying hands to extending one to communities in need, our authors in JoVE Behavior describe a strategy to directly engage women at high socio-demographic risk for preterm birth. The Research Prioritization by Affected Communities protocol represents big step forward in the involvement of patients and the public in setting research priorities.
Next, as athletes across the globe prepare to compete for Olympic gold, JoVE Bioengineering features a method to synthesize gold nanoparticles for use in targeted drug delivery. After synthesis and purification, these fluorescent nanoparticles can be visualized both in vitro and in vivo.
Finally, JoVE Bioengineering was honored to feature the work of a Nobel laureate and colleagues, who share their protocol to prepare and purify liposomes. Using these liposomes, researchers can answer key questions related to synthetic biology and the origin of life.

This manuscript describes the Research Prioritization by Affected Communities (RPAC) protocol and findings from its use with women at risk for preterm birth. Using the protocol, women identified and prioritized their unanswered questions about pregnancy, birth and neonatal care aimed at influencing research priority setting by funders and researchers.

This protocol describes how to use frame-by-frame video analysis to quantify idiosyncratic reach-to-grasp movements in humans. A comparative analysis of reaching in sighted versus unsighted healthy adults is used to demonstrate the technique, but the method can also be applied to the study of developmental and clinical populations.

We describe a method of synthesizing biocompatible 10-nm gold nanoparticles, functionalized by coating poly-ethylene glycol onto the surface. These particles can be used in vitro and in vivo for delivering therapeutics to nanoscale cellular and extracellular spaces that are difficult to access with conventional nanoparticle sizes.

Liposomes containing single-chain amphiphiles, particularly fatty acids, exhibit distinct properties compared to those containing diacylphospholipids due to the unique chemical properties of single chain amphiphiles. Here we describe techniques for the preparation, purification, and use of liposomes comprised in part or whole of these amphiphiles.
