FEBS Open Bio, EarlyView.Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Evaluating the involvement of autolysosomes in the nuclear translocation of fluorescent proteins
FEBS Open Bio, EarlyView.Endogenously expressed fluorescent proteins can be degraded by autophagy and transported to cell nuclei via the nuclear pore complex. But in some cell lines, for example, HeLa cells which are positive for immunoreactivity of a receptor ligand, such as UCN I, in cell nuclei, fusion of autolysosome with the nuclear envelope is involved in the nuclear ...

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells
FEBS Open Bio, EarlyView.Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

The path followed by a robotic manipulator is often defined by a sequence of Cartesian knots, i.e., position and orientation (location) of the end effector and the corresponding linear and angular velocity (speed) at each knot. The path location and speed in the interval between knots are not specified.

Development of an End-Effector for Mitigation of Collisions
Volume 7: 17th IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications (MESA), 2021Abstract In robotics the risk of collisions is present both in industrial applications and in remote handling. If a collision occurs, the impact may damage both the robot and external equipment, which may result in successive imprecise robot tasks or line stops, reducing robot efficiency.

A medium-complexity compliant end effector
Proceedings. 1988 IEEE International Conference on Robotics and Automation, 2003The design of an end effector under development at Pennsylvania University is reported. The rationale supporting this mechanism is explored, its geometry is described and experimental results from the first prototype are presented. The gripper has three fingers, one fixed with respect to the palm and the other two able to rotate synchronously about ...

End-effector position-orientation measurement
IEEE Transactions on Robotics and Automation, 1999A low-cost device is presented for noncontact measurement of robot position and orientation. It consists of an optical sensor and three laser scanners. The sensor is attached to the end-effector while the laser scanners cast light planes to trace the sensor movement. The device measures equations of the light planes from which end-effector position and
