Biodegradable micro- and nanoparticles have the potential to reform the drug development landscape by improving drug solubility, changing undesirable pharmacokinetics, realizing the benefits of new molecules arising from genomic and proteomic research, and increasing drug localization in target organs and tissues; i.e., drug targeting. This review provides an overview of the in vivo fate of biodegradable particulate carriers following administration via several routes, as well as how the patient's health state, disease pathophysiology and particle physicochemical properties affect such fates. It also discusses some of the widely used biodegradable polymers, their in vivo biochemical degradation, methods of nanoparticle formulation from such polymers and finally, how such methods could be tailored to achieve targeted delivery to specified tissues both passively and actively.

The moderating and mediating role of the placenta in the association between prenatal exposure to air pollutants and birth weight: A twin study.
Environ Res

Prenatal exposure to air pollution has been linked to lower birth weight, yet the role of the placenta in this association is often overlooked. This study investigates whether placental characteristics act as moderators or mediators in the association between prenatal exposure to particulate matter (PM) and nitrogen dioxide (NO) and birth weight in twins. The study included 3340 twins (born 2002-2013) from the East Flanders Prospective Twin Survey.

This review explores the impact of various additives on the mechanical properties of polylactic acid (PLA) filaments used in Fused Deposition Modeling (FDM) 3D printing. While PLA is favored for its biodegradability and ease of use, its inherent limitations in strength and heat resistance necessitate enhancements through additives. The impact of natural and synthetic fibers, inorganic particles, and nanomaterials on the mechanical properties, printability, and overall functionality of PLA composites was examined, indicating that fiber reinforcements, such as carbon and glass fibers, significantly enhance tensile strength and stiffness, while natural fibers contribute to sustainability but may compromise mechanical stability.

Particulate matter (PM) is a major component of ambient air pollution. PM exposure is linked to numerous adverse health effects, including chronic lung diseases. Air quality guidelines designed to regulate levels of ambient PM are currently based on the mass concentration of different particle sizes, independent of their origin and chemical composition.

Background: Asthma is a common respiratory disease in children, and air pollution is a risk factor for pediatric asthma. However, how air pollution affects blood cells in pediatric patients with asthma remains unclear.
Methods: This retrospective observational study, performed in 2007-2018 at a medical center, enrolled non-trauma patients aged < 17 years who visited the emergency department and had asthma.
