Decisions made over long time scales, such as life cycle decisions, require coordinated interplay between sensory perception and sustained gene expression. The dauer (or diapause) exit developmental decision requires sensory integration of population density and food availability to induce an all-or-nothing organismal-wide response, but the mechanism by which this occurs remains unknown. Here, we demonstrate how the Amphid Single Cilium J (ASJ) chemosensory neurons, known to be critical for dauer exit, perform sensory integration at both the levels of gene expression and calcium activity.

Background: The dynamicity and mobility of the population in a mass gathering setting pose a challenge to traditional disease surveillance methods and strain the local health services. Velankanni is one of the most sacred Christian pilgrimage places located in Nagapattinam, Tamil Nadu, India. We participated in the Velankanni festival to describe the public health preparedness, surveillance, and response activities carried out during the festival.

Introduction: Prosthetic rehabilitation with implants in the atrophic edentulous maxilla often requires a bone augmentation procedure to enable implant placement and integration. However, rigid anchorage can also be achieved using long zygomatic implants. The aim of this study was to evaluate the surgical outcomes of rehabilitation of atrophic posterior maxillary ridges with zygomatic implants using the zygomatic success code (ZSC) and derive the success grade for the procedure based on the observed results.
