Update on Conventional Osteosarcoma.

Conventional osteosarcoma is a high-grade malignant tumor characterized by the production of osteoid matrix by malignant osteoblasts. It typically affects the long bones of children and adolescents. Treatment includes systemic chemotherapy and a local surgical approach with wide resection.

How does the tidal cycle influence the estuarine dynamics of microplastics?

Estuaries are the main pathway for the microplastics (MPs) to enter into the oceans. However, factors that drive river-sea transport of MPs are not yet fully understood. Therefore, our research investigated the influence of the tidal cycle on the abundance and characteristics of MPs in an urban estuary, through high-frequency sampling (every 2-3 h) using a plankton net (120 μm mesh size) in two seasons (rainy and dry seasons).

[Under a pestilent land of lies: misinformation and denialism in the smallpox epidemic in Ceará, Brazil, 1900-1905, and the covid-19 pandemic in Brazil, 2020-2022].

The article draws a parallel between two pathological phenomena with great social impact in different settings: the smallpox epidemic in Ceará, northeastern Brazil, between 1900 and 1905, and the covid-19 pandemic in Brazil between 2020 and 2022. Despite the historical and temporal distance between these two episodes, there are some significant similarities in the ways they were conducted politically, especially with regard to the use of fake news and misinformation on the emergency of implementing mass vaccination. The analysis makes extensive use of press reports concerning the covid-19 pandemic and writings by the pharmacist Rodolfo Teófilo, a key figure in the smallpox vaccination campaign in Ceará.

Nose-to-Brain Delivery of Biomimetic Nanoparticles for Glioblastoma Targeted Therapy.

Glioblastoma (GBM) is an extremely aggressive form of brain cancer that remains challenging to treat, especially owing to the lack of effective targeting and drug delivery concerns. Due to its anatomical advantages, the nose-to-brain strategy is an interesting route for drug delivery. Nanoengineering has provided technological tools and innovative strategies to overcome biotechnological limitations, which is promising for improving the effectiveness of conventional therapies.

Kolmogorov-Arnold Network in the Fault Diagnosis of Oil-Immersed Power Transformers.

Instabilities in energy supply caused by equipment failures, particularly in power transformers, can significantly impact efficiency and lead to shutdowns, which can affect the population. To address this, researchers have developed fault diagnosis strategies for oil-immersed power transformers using dissolved gas analysis (DGA) to enhance reliability and environmental responsibility. However, the fault diagnosis of oil-immersed power transformers has not been exhaustively investigated.
