SoxT1A mutants are sulfur oxidation-negative despite high transcription levels of sulfur oxidation genes, showing that SoxT1A delivers sulfur to the cytoplasm for its further oxidation. SoxT1B serves as a signal transduction unit for the transcriptional repressor SoxR, as SoxT1B mutants are sulfur oxidation-negative due to low transcription unless SoxR is also absent.

This study aims to investigate the impact of poly(lactic-co-glycolic acid)/Bradykinin (PLGA/BK) microspheres on IVDD and its underlying mechanisms. We collected nucleus pulposus samples from both healthy and degenerated human intervertebral disks and conducted immunohistochemical analyses, revealing reduced BK expression in degenerated tissues. Subsequently, we used BK to treat nucleus pulposus cells and conducted Bulk RNA sequencing (RNA-seq), identifying BK's involvement in cellular senescence, extracellular matrix metabolism, and the PI3K signaling pathway. Further experiments using tert-butyl hydroperoxide (TBHP)-induced cell senescence showed that BK treatment reduced senescence, enhanced extracellular matrix synthesis, and inhibited degradation, along with activation of the PI3K pathway. These effects were mediated through B2R (BK receptor 2) and the downstream PI3K pathway. Following this, we developed sustained-release BK microspheres with an optimized manufacturing process. In vitro co-culture experiments showed no observable toxicity. We established an IVDD model in rat tail vertebrae through fine needle puncture, administering local injections of BK sustained-release microspheres. Using various experimental methods, including X-ray, MRI, histopathology, and immunohistochemistry, we found that these microspheres could slow the progression of IVDD.

We introduce an agent-based model that captures key data features. Specifically, in response to chasing, the sheep change their spatial relative positions less frequently and exhibit a transfer of directional information flow from front to back; this pattern disappears in the absence of chasing.

The process of wound healing requires strict regulation, and its disruption can lead to the formation of chronic wounds, which can have a significant impact on an individual's health as well as on worldwide healthcare expenditure. One essential aspect within the cellular and molecular regulation of wound healing pathogenesis is that of reactive oxygen species (ROS) and oxidative stress. Wounding significantly elevates levels of ROS, and an array of various reactive species are involved in modulating the wound healing process, such as through antimicrobial activities and signal transduction. However, as in many pathologies, ROS play an antagonistic pleiotropic role in wound healing, and can be a pathogenic factor in the formation of chronic wounds. Whilst advances in targeting ROS and oxidative stress have led to the development of novel pre-clinical therapeutic methods, due to the complex nature of ROS in wound healing, gaps in knowledge remain concerning the specific cellular and molecular functions of ROS in wound healing.

We investigated the impact of noise with different spectral compositions on the vibrational communication of the stink bug Nezara viridula, examining courtship behaviour and signal representation by sensory neurons. We found negative effects of vibrational noise regardless of spectral overlap, challenging common expectations. Noise impaired the ability of males to recognize the female signal and localise its source: overlapping noise decreased sensitivity of receptor neurons to the signal and disrupted signal frequency encoding by phase-locking units, while non-overlapping noise only affected frequency encoding. Modelling neuronal spike triggering in sensory neurons linked disrupted frequency encoding to interference-induced alterations of the signal waveform. These alterations also affected time delays between signal arrivals to different legs, crucial for localisation.
