Methods and systems for converting precursor cells into intestinal tissues through directed differentiation
The generation of complex organ tissues from human embryonic and pluripotent stem cells (PSCs) remains a major challenge for translational studies. It is shown that PSCs can be directed to differentiate into intestinal tissue in vitro by modulating the combinatorial activities of several signaling pathways in a step-wise fashion, effectively recapitulating in vivo fetal intestinal development. The resulting intestinal “organoids” were three-dimensional structures consisting of a polarized, columnar epithelium surrounded by mesenchyme that included a smooth muscle-like layer. The epithelium was patterned into crypt-like SOX9-positive proliferative zones and villus-like structures with all of the major functional cell types of the intestine. The culture system is used to demonstrate that expression of NEUROG3, a pro-endocrine transcription factor mutated in enteric anendocrinosis is sufficient to promote differentiation towards the enteroendocrine cell lineage. In conclusion, PSC-derived human intestinal tissue should allow for unprecedented studies of human intestinal development, homeostasis and disease. |

The input gear and output gear are both rotatable with the propeller input shaft. The brake shaft is coupled to, and is rotatable with, the output gear. The brake assembly is coupled to the brake shaft and is moveable between a disengaged position, in which the brake shaft may rotate whenever the output gear rotates, and an engaged position, in which the brake shaft is prevented from rotating, thereby preventing rotation of the output gear, the input gear, and the propeller input shaft. |

Low profile pass-through electrical connector
A low profile pass-through electrical connector is designed for aerospace applications. The connector allows voltage and current to pass-thru a conductive wing surface, while maintaining a low profile height for aerodynamic performance considerations. Examples of applications of the electrical connector include power for thin film heaters and communication antennae applications. |

Tray table with detent mechanism
A detent mechanism is provided for a tray table of an aircraft. The detent mechanism includes an actuator configured to move along with a table leaf of the tray table as the table leaf rotates between a stowed position and a deployed position of the table leaf. The detent mechanism includes a follower biased toward an open position of the follower. The follower is configured to be moved against the bias from the open position into a closed position of the follower by engagement of the actuator with the follower as the table leaf rotates from the stowed position into the deployed position. The follower includes a magnetic component configured to releasably hold the follower in the closed position. |

Floor dryer in an aircraft lavatory
A system to distribute air across a lavatory floor is disclosed herein. The system includes a dryer unit and at least one sensor in an aircraft lavatory coupled to a locking mechanism of the aircraft lavatory responsive to an action comprising an actuation of a slide switch to open the locking mechanism of a door of the aircraft lavatory wherein the dryer unit is electronically coupled to the at least one sensor. In response to a detection by at least one sensor of the actuation of the slide switch to open the locking mechanism of the door of the aircraft lavatory, the dryer unit is configured to receive a command from a processor communicatively coupled to the at least one sensor to cause the dryer unit to be activated. |
