Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy
Advanced Science, EarlyView.Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.

C-Space Compression for Robots Motion Planning
International Journal of Advanced Robotic Systems, 2013 Exact motion planning for hyper-redundant robots under complex constraints is computationally intractable. This paper does not deal with the optimization of motion planning algorithms, but rather with the simplification of the configuration space ...

Advanced Science, EarlyView.This study employs sc‐RNA sequencing, genetics, and phenotyping to systematically map the cell‐type‐specific immune responses triggered by flg22. It reveals FLS2‐dependent transcriptional reprogramming in epidermal and mesophyll cells, and uncovers crosstalk between immune and hypoxia signaling pathways.

Advanced Science, EarlyView.ETV4 coordinates a dual transcriptional program by upregulating MET and asparagine synthetase (ASNS). The resulting asparagine (Asn) secretion acts as a metabolic signal, reprogramming hepatic stellate cells (HSCs) and primary cancer‐associated fibroblasts (CAFs) toward an inflammatory phenotype. These activated stromal cells release HGF to sustain the

Hyper-redundant robot mechanisms and their applications [PDF]
Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91, 2002 Hyper-redundant robots have a large or infinite number of degrees of freedom. Such robots are analogous to snakes or tentacles and are useful for operation in highly constrained environments and novel forms of locomotion. The paper reviews newly developed methods for the kinematic analysis of hyper-redundant manipulators.
