Tunable Dynamics in a Multistrain Transcriptional Pulse Generator.

One challenge in synthetic biology is the tuning of regulatory components within gene circuits to elicit a specific behavior. This challenge becomes more difficult in synthetic microbial consortia since each strain's circuit must function at the intracellular level and their combination must operate at the population level. Here we demonstrate that circuit dynamics can be tuned in synthetic consortia through the manipulation of strain fractions within the community.

Infantile Respiratory Distress Syndrome and Its Probable Links With Parameters of the Maternal Patient History: A Forensic Case Report.

Respiratory distress syndrome (RDS) has a major contribution to neonatal mortality worldwide. Multiple factors associated with increased risk for RDS have been documented to effectively understand the emergence and progression of this disorder. A portion of these parameters has been broadly examined whereas the role of others, despite being clinically described, has not been fully evaluated.
