On–Off Switchable Micromotors for Use in Steerable Microvehicles
Advanced Robotics Research, EarlyView.Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Advanced Robotics Research, EarlyView.Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

In defense of the lung: surfactant protein A and surfactant protein D
Current Opinion in Pharmacology, 2006The lung is repeatedly exposed to inhaled particles and pathogens that are cleared by the actions of a multi-component innate host defense system. The pulmonary collectins--surfactant proteins A (SP-A) and D (SP-D)--play important roles in innate host defense by binding and clearing invading microbes from the lung.

Surfactant protein D is proatherogenic in mice
American Journal of Physiology-Heart and Circulatory Physiology, 2006Surfactant protein D (SP-D) is an important innate immune defense molecule that mediates clearance of pathogens and modulates the inflammatory response. Moreover, SP-D is involved in lipid homeostasis, and pulmonary accumulation of phospholipids has previously been observed in SP-D-deficient ( Spd−/−) mice. Atherogenesis involves both inflammation and

.The lipid and protein components of surfactant are syn thesized and secreted by the alveolar type II epithelial cell. Newly secreted surfactant adsorbs to the alveolar air-liquid interface, where it spreads as a monomolecular film that serves to reduce surface tension during expiration.

The collectins can be classed into two distinct group, with MBP and SP-A being hexamers and SP-D, conglutinin and collectin-43 (CL-43) being tetramers, with proteins in the latter group also having significantly larger dimensions with respect to the length of their collagen-like ‘stalks’ (Lu et al. 1993).

Degradation of surfactant protein D by alveolar macrophages
American Journal of Physiology-Lung Cellular and Molecular Physiology, 1998Surfactant protein (SP) D is a pulmonary surfactant-associated protein that may function in lung host defense. SP-D is produced by alveolar type II cells and nonciliated bronchiolar epithelial (Clara) cells of the airway and is secreted into the air space. Here we investigated whether alveolar macrophages degraded SP-D in vitro.

Surfactant protein D (SPD) is a member of the collectin family that lines the airway epithelial cells with host defense. However, the role of SPD in the pathogenesis of aspirin‐exacerbated respiratory disease (AERD) is still unclear.

The roles of surfactant proteins A and D in innate immunity
Immunological Reviews, 2000Summary: Research over the last decade on the surfactant proteins SP‐A and SP‐D suggests roles beyond surfactant lipid homeostasis, involving their participation in innate immune defence. SP‐A and SP‐D bind and agglutinate an impressive array of non‐self structures, ranging from bacteria and fungi to allergens and environmental inorganic substrates ...
