Purinergic signalling in systemic sclerosis
Rheumatology, 2021 Abstract SSc is a chronic autoimmune rheumatic disease that involves numerous organs and presents major management challenges. The histopathologic hallmarks of SSc include vasculopathy, fibrosis and autoimmune phenomena involving both innate and adaptive immune systems.

Systems theory of Smad signalling [PDF]
IEE Proceedings - Systems Biology, 2006 Transforming Growth Factor-beta (TGF-beta) signalling is an important regulator of cellular growth and differentiation. The principal intracellular mediators of TGF-beta signalling are the Smad proteins, which upon TGF-beta stimulation accumulate in the nucleus and regulate transcription of target genes.

Full-Bridge Diode-Clamped Four-Level Symmetric Switching Converter
IEEE Access, 2023 In this paper, we propose a novel full-bridge (FB) diode-clamped four-level symmetric switching converter. Multi-neighboring reference vector discontinuous PWM (MNRV DPWM) for FB topology was implemented using a symmetric half-bridge (HB)-based control ...

Content in Simple Signalling Systems [PDF]
The British Journal for the Philosophy of Science, 2018 Our understanding of communication and its evolution has advanced significantly through the study of simple models involving interacting senders and receivers of signals. Many theorists have thought that the resources of mathematical information theory are all that are needed to capture the meaning or content that is being communicated in these systems.

Cold Signaling via the Two-Component Signaling System [PDF]
Molecular Plant, 2013 Two-component signal transduction is commonly used as a stimulus–response coupling mechanism to allow organisms such as eubacteria, archea, and a few eukaryotes to sense and respond to changes in many different environmental conditions (Stock et al., 2000).

Three-Phase Diode-Clamped Four-Level PWM Inverter With Offset Voltage Injection
IEEE AccessIn this paper, a three-phase diode-clamped four-level PWM inverter with offset voltage injection is proposed. The proposed inverter is based on multi-neighboring reference vector (discontinuous) pulse-width modulation (MNRV (D)PWM), where multiple ...

Modularity in signaling systems [PDF]
Physical Biology, 2012 Modularity is a property by which the behavior of a system does not change upon interconnection. It is crucial for understanding the behavior of a complex system from the behavior of the composing subsystems. Whether modularity holds in biology is an intriguing and largely debated question.

Bactericidal antibiotic treatment induces damaging inflammation via TLR9 sensing of bacterial DNA
Nature CommunicationsThe immunologic consequences of using bactericidal versus bacteriostatic antibiotic treatments are unclear. We observed a bacteriostatic (growth halting) treatment was more protective than a bactericidal (bacteria killing) treatment in a murine ...
