Appropriate tension sensitivity of α-catenin ensures rounding morphogenesis of epithelial spheroids
The adherens junction (AJ) is an actin filament-anchoring junction. It plays a central role in epithelial morphogenesis through cadherin-based recognition and adhesion among cells.

For the current goal of expanding into the solar system, environmental control and life support systems (ECLSS) are required for humans to survive the hostile environments of deep space. To support this goal, biological subsystems can produce food and close the carbon loop. These subsystems include algae, microbes and higher plants which can complement

Spacecraft Life Support Systems [PDF]
<div class="section abstract"> <div class="htmlview paragraph">A life support system (LSS) is usually defined as a system that provides elements necessary for maintaining human life and health in the state required for performing a prescribed mission. The LSS, depending upon specific design requirements, will provide pressure, temperature,

Meta-Analysis of Hypoxic Transcriptomes from Public Databases
Hypoxia is the insufficiency of oxygen in the cell, and hypoxia-inducible factors (HIFs) are central regulators of oxygen homeostasis. In order to obtain functional insights into the hypoxic response in a data-driven way, we attempted a meta-analysis of ...

Dynamic Considerations for Control of Closed Life Support Systems [PDF]
Reliability of closed life support systems depend on their ability to continue supplying the crew's needs during perturbations and equipment failures. The dynamic considerations interact with the basic static design through the sizing of storages, the ...

Novel Multi-Functional Life Support System
Concepts of cardiopulmonary support (CPS), extra-corporeal membrane oxygenation (ECMO), and ventricular support (VS) have been thoroughly studied and refined. These perfusion adjuncts often require multiple devices, skill sets, and significant financial burden to purchase, maintain, deploy, and use. We describe a novel system that is rapidly deployable,
