Exposure to pulmonary tuberculosis (PTB) culminates in heterogeneous outcomes, including variation in Mtb antigen-specific interferon-gamma (IFN-γ) T-cell responses. IFN-γ-independent cytokines, including tumor necrosis factor (TNF) and interleukin (IL-2), offer potential diagnostic improvements and insights into pathogenesis. We hypothesized that ESAT6/CFP10 TNF and IL-2 responses improve Mtb infection detection among exposed household contacts (HHCs) and are associated with index case Mtb aerosolization (i.

This study aims to identify key inflammatory mediators related to this clinically significant immunologic response.
Methods: Pediatric patients were enrolled in a single-arm prospective clinical study (NCT05154864) and received standard cardiac operation, CPB and subzero-balance ultrafiltration.
PIK-75 (F7) is a potent multikinase inhibitor that targets p110α, DNA-PK, and p38γ. PIK-75 has shown potential as a therapy in preclinical cancer models, but it has not been used in the clinic, at least in part, due to limited solubility. We therefore developed a nanoparticle to encapsulate PIK-75 and enable targeted cellular delivery.

For nitrate, which is subject to subsurface denitrification, it is therefore important to assess the spatial variability and temporal stability of groundwater redox conditions, as nitrate reduction typically occurs in reducing conditions. This paper presents a robust assessment of a large groundwater quality data set collected across New Zealand landscapes, develops methods to impute missing groundwater redox-sensitive variables and characterises the spatial variability and temporal stability of groundwater redox conditions against relevant landscape hydrogeochemical characteristics.
