Class-A penicillin binding proteins do not contribute to cell shape but repair cell-wall defects

eLife, 2020
Cell shape and cell-envelope integrity of bacteria are determined by the peptidoglycan cell wall. In rod-shaped Escherichia coli, two conserved sets of machinery are essential for cell-wall insertion in the cylindrical part of the cell: the Rod complex ...

EpCAM in morphogenesis

Frontiers in Bioscience, 2008
Embryonic development is one of the most complex biological phenomena that involves the appropriate expression and synchronized interactions of a plethora of proteins, including cell adhesion molecules (CAMs). Many members of the diverse family of CAMs have been shown to be critically involved in the correct execution of embryonic development.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Discrimination of Brazilian propolis according to the seasoning using chemometrics and machine learning based on UV-Vis scanning data

Journal of Integrative Bioinformatics, 2015
Propolis is a chemically complex biomass produced by honeybees (Apis mellifera) from plant resins added of salivary enzymes, beeswax, and pollen. The biological activities described for propolis were also identified for donor plant’s resin, but a big ...

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications

Advanced Robotics Research, EarlyView.
Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

Magnetically Actuated Microrobot for Drug Delivery: Current Progress and Challenges

Advanced Robotics Research, EarlyView.
Magnetically actuated microrobots are reshaping targeted drug delivery through wireless propulsion, programmable materials, and localized therapeutic release. This review examines how fabrication, body material selection, structural architecture, loading mechanisms, and imaging‐guided control converge to enable microrobotic therapies while identifying ...

Characterisation of morphogenesis mutants in Arabidopsis [PDF]

, 1998
In this thesis is described the identification and characterisation of two morphogenesis mutants of Arabidopsis thaliana. One, vertically challenged (vch1) exhibits much reduced cellular elongation. The second, altered suspensor fate (asf1) is embryonic-

Charting Endocrine Progenitors Across Species and Organs

Advanced Science, EarlyView.
Endocrine progenitors give rise to the hormone‐producing cells of the pancreas and intestine. Using single‐cell multiomics and proteomics, this study compares these progenitors across species, systems, and organs, mapping the conserved and species‐specific gene regulatory networks that guide their formation.
