Bifidobacterium Pseudolongum‐Derived Acetate Attenuates Acute Pancreatitis Through GPR43‐Mediated Suppression of M1 Macrophage Polarization

Advanced Science, EarlyView.
The severity of acute pancreatitis (AP) is linked to reduced abundance of Bifidobacterium pseudolongum (B. pseudolongum). Administration of B. pseudolongum or its key metabolite acetate alleviates pancreatic and systemic inflammation by suppressing M1 macrophage polarization.

SMAD4 Palmitoylation Drives a Metabolic‐Transcriptional Circuit to Promote Tumorigenesis and Confers Radiosensitivity in Pancreatic Cancer

Advanced Science, EarlyView.
This study identifies palmitoylation as a novel regulatory modification of SMAD4, mediated by ZDHHC22/APT2. It activates fatty acid synthesis, creating a self‐reinforcing SMAD4–FASN–palmitate feedback loop that drives pancreatic cancer growth and enhances radiotherapy sensitivity.

Robust Point Clouds Registration

, 2017
Point clouds registration is a very well studied problem, with many different and efficient solutions. Nevertheless, the approaches in the literature rely heavily on a good initialization and on a good set of parameters. These approaches could be roughly divided into two categories: those based on features and the so-called closest-point-based.
