The pyruvate generator is a common phenomenon in mitochondria from different rat and mouse brain regions

open access: yesFEBS Letters, EarlyView.
The pyruvate generator, which causes activation of respiration by extra‐mitochondrial Ca2+, is also present and functional in rat brainstem mitochondria, as it is in other brain regions. This finding is confirmed by experiments with a fully reconstituted malate–aspartate shuttle (MAS).

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Configuration Design for 6-DOF Master Manipulator and Research on Spatial Trajectory Planning Simulation

open access: yesJixie chuandong, 2021
The master manipulator is an important part for minimally invasive surgical (MIS)robot. It is used to receive the doctor action and control the slave operator to complete the surgical operation.

Master-slave teleoperation method of redundant manipulator

open access: yes, 2013
This paper introduces a master-slave control method of teleoperating a redundant manipulator with double handles. The master handles send motion commands in the form of increments. The mapping module transforms the commands into homogeneous matrices. And

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Kinematics and Workspace Analysis of an 8-DOF Space Manipulator

open access: yesJixie chuandong, 2021
An 8-DOF manipulator with prismatic pair is proposed for space environment, which can complete equipment maintenance and object grabbing in space environment. The pose transformation matrix and forward kinematics equation of 8-DOF manipulator are derived

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

open access: yesFEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.

A visual feedback system for micromanipulation with stereoscopic microscope

open access: yes, 1998
A stereoscopic microscope is widely used in a micromanipulation such as to operate genes and to inspect integration circuits. As in these tasks the micromanipulation is handled and makes too heavy burden to operators, it is desirable to perform the ...
