Strategies to Modulate the Redifferentiation of Chondrocytes [PDF]
Frontiers in Bioengineering and Biotechnology, 2021 Because of the low self-healing capacity of articular cartilage, cartilage injuries and degenerations triggered by various diseases are almost irreversible. Previous studies have suggested that human chondrocytes cultured in vitro tend to dedifferentiate during the cell-amplification phase and lose the physiological properties and functions of the ...

Hybrid Modulation Strategy for the Vienna Rectifier [PDF]
IEEE Transactions on Power Electronics, 2021 The Vienna rectifier can produce three voltage levels, however only the connection to the neutral-point is fully controllable using the bidirectional switches. When the neutral-point voltage is not imposed in a phase-leg, the polarity of the pulses generated depends on the diode that is conducting in that phase-leg, which is defined by the current ...

Vaccination Strategies and Immune Modulation of Atherosclerosis [PDF]
Circulation Research, 2020 Adaptive as well as innate immune responses contribute to the development of atherosclerosis. Studies performed in experimental animals have revealed that some of these immune responses are protective while others contribute to the progression of disease.

Modulation of Apoptosis As a Therapeutic Strategy [PDF]
The Scientific World Journal, 2001 Cell death is a contributing factor in many human diseases. A significant proportion of the cell loss that occurs in tissue or organ injury and disease is by programmed cell death, or apoptosis. Apoptosis is a genetically controlled form of cell suicide effected by specific gene products acting within dying cells.

TREM-1 Modulation Strategies for Sepsis
Frontiers in Immunology, 2022 The triggering receptor expressed on myeloid cells-1 (TREM-1) is a pattern recognition receptor, which can be upregulated in inflammatory diseases as an amplifier of immune responses. Once activated, TREM-1 induces the production and release of pro-inflammatory cytokines and chemokines, in addition to increasing its own expression and circulating ...

Gravity modulates behaviour control strategy [PDF]
Experimental Brain Research, 2019 Human behaviour is a trade-off between exploitation of familiar resources and exploration of new ones. In a challenging environment-such as outer space-making the correct decision is vital. On Earth, gravity is always there, and is an important reference for behaviour. Thus, altered gravitational signals may affect behaviour control strategies.

IEEE Access, 2020 As the grid-connected AC-DC converter is the key equipment that links the low voltage direct current (LVDC) microgrids and the utility grid, the safe and stable operation of the converter is of great significance to improve the reliability of the LVDC ...

Modulation Strategy for Suppressing Peak Voltage Spikes of SiC-MOSFETs During ANPC Commutation
IEEE Access, 2023 After active neutral point clamped(ANPC) adopts SiC-MOSFETs, SiC-MOSFETs are easily damaged due to the excessive peak voltage. This paper establishes a single-phase parasitic inductance model of ANPC based on the SiC-MOSFET half-bridge modules.

Modulating autophagy: a strategy for cancer therapy [PDF]
Chinese Journal of Cancer, 2011 Autophagy is a process in which long-lived proteins, damaged cell organelles, and other cellular particles are sequestered and degraded. This process is important for maintaining the cellular microenvironment when the cell is under stress. Many studies have shown that autophagy plays a complex role in human diseases, especially in cancer, where it is ...

Modulating Cell Fate as a Therapeutic Strategy [PDF]
Cell Stem Cell, 2018 In injured tissues, regeneration is often associated with cell fate plasticity, in that cells deviate from their normal lineage paths. It is becoming increasingly clear that this plasticity often creates alternative strategies to restore damaged or lost cells.
