Comparative analysis of acute and chronic toxicological exposure effects of polystyrene nanoparticles on Macrobrachium rosenbergii: Implications for antioxidative defense and immunosuppression.

Global pollution by microplastics (MPs) and nano-plastics (NPs) disrupts aquatic ecosystems and compromises the health of aquatic animals. However, there is a significant gap in the literature regarding acute high-dose and chronic low-dose polystyrene nano-plastic (PS-NP) exposures that simulate point-source and non-point source pollution events, respectively. The PS-NP concentrations (10 mg/L for acute exposure and 1 mg/L for chronic exposure) were designed to simulate realistic environmental scenarios.

Maternal antibody transfer efficiency: The impact of M. bovis-BoHV-1 combined vaccine.

Bovine respiratory disease (BRD) is a complex and one of the most costly diseases caused by multiple bacterial and viral infections. Cattle of almost all ages are susceptible to BRD, with young day-old newborn calves being the most at risk. The ability of newborn calves to acquire passive immunity from milk, appears to be a critical issue in immunological evaluation.

Real-Time Open Source Kinematic Estimation with Wearable IMUs.

Despite the growing demand for healthcare services due to an aging population, patients may avoid traditional rehabilitation centers due to high costs, discomfort, and time constraints associated with in-person assessments.
