Collective oscillatory signaling in Dictyosteliumdiscoideum acts as a developmental timer initiated by weak coupling of a noisy pulsatile signal.

Oscillatory phenomena play widespread roles in the control of biological systems. In D. discoideum, oscillatory cyclic adenosine monophosphate (cAMP) signaling drives collective behavior and induces a temporal developmental gene expression program.

Barriers to Postdischarge Smartphone App Use Among Patients With Traumatic Rib Fractures.

Rib fractures commonly result from traumatic injury and often require hospitalization for pain control and supportive pulmonary care. Although the use of mobile health technology to share patient-generated health data has increased, it remains limited in patients with traumatic injuries. We sought to assess the feasibility of mobile health tracking in patients with rib fractures by using a smartphone app to monitor postdischarge recovery.

A novel class of insecticidal alkylsulfones are potent inhibitors of vesicular acetylcholine transport.

Pyridine alkylsulfone derivatives typified by oxazosulfyl (Sumitomo Chemical Company Ltd.) and compound A2 (Syngenta) represent a new class of insecticides, with potent activity against several insect orders. Whilst the MOA of this class has been attributed to interaction with the voltage-gated sodium channel (VGSC), here we present strong evidence that their toxicity to insects is mediated primarily through inhibition of the vesicular acetylcholine transporter (VAChT).

Barriers and facilitators to parents' engagement with and perceived impact of a childhood obesity app: A mixed-methods study.

Childhood obesity is a growing global health concern. Although mobile health apps have the potential to deliver behavioural interventions, their impact is commonly limited by a lack of sufficient engagement. The purpose of this study was to explore barriers and facilitators to engagement with a family-focused app and its perceived impact on motivation, self-efficacy, and behaviour.

Functional mechanism study of the allelochemical myrigalone A identifies a group of ultrapotent inhibitors of ethylene biosynthesis in plants.

Allelochemicals represent a class of natural products released by plants as root, leaf, and fruit exudates that interfere with the growth and survival of neighboring plants. Understanding how allelochemicals function to regulate plant responses may provide valuable new approaches to better control plant function. One such allelochemical, Myrigalone A (MyA) produced by Myrica gale, inhibits seed germination and seedling growth through an unknown mechanism.
