Cardiac Organoid Model Inspired Micro‐Robot Smart Patch to Treat Myocardial Infarction
Advanced Materials, EarlyView.The heart organoid model exhibits the acidic microenvironment characteristic of myocardial infarction, which emerges as a pivotal force propelling the movement of micro‐robots. These micro‐robots, administered through microneedles, can penetrate deep into the tissue, effectively delivering therapeutic payloads to facilitate heart repair.

Positioning Crenarchaeal tRNA-Introns [PDF]
arXiv, 2005 We precisely position a noncanonical intron in the odd second copy of tRNAAsp(GTC) gene in the newly sequenced crenarchaea S.acidocaldarius. The uniform assortment of some features from normal aspartate tDNA and some from those corresponding to non-standard amino acids conduce us to conjecture it to be a novel tRNA gene, probably coding for a modified ...

Engineering Bacterial Secretion Systems for Enhanced Tumor Imaging and Surgical Guidance
Advanced Materials, EarlyView.This study presents a novel contrast agent platform, Streptavidin Associated Salmonella (SAS), for fluorescence image guided surgery. SAS selectively colonizes tumors and secretes streptavidin, enabling precise delineation of invasive tumor margins with prolonged signal retention.

The Biosynthetic Order of Amino Acid Addition to the Genetic Code [PDF]
arXiv, 2002 The previously formulated model for the evolution of the genetic code was shown to clarify why base triplets of some precursor amino acids differ by a single base from product amino acid codons, while others show less homology. First, the model indicated that the direction of code evolution changed on expansion from the N-fixers code (stage 2).

A Mathematical Description of Bacterial Chemotaxis in Response to Two Stimuli [PDF]
arXiv, 2020 Bacteria are often exposed to multiple stimuli in complex environments, and their efficient chemotactic decisions are critical to survive and grow in their native environments. Bacterial responses to the environmental stimuli depend on the ratio of their corresponding chemoreceptors.

Extending integrate-and-fire model neurons to account for the effects of weak electric fields and input filtering mediated by the dendrite [PDF]
, 2016 How extracellular electric fields, as generated endogenously or through transcranial brain stimulation, affect the dynamics of large neuronal populations is of great interest but not well understood. To study the collective dynamics of large populations single-compartment (point) model neurons have been proven very successful.
