Robotic liver transplantation represents a cutting-edge technique that may surpass traditional open surgery. Nonetheless, it introduces unique anesthetic challenges, including extended pneumoperitoneum, restricted patient access, and a risk of undetected blood loss. This article describes an anesthetic approach and patient outcomes for the first four total robotic liver transplants performed at a tertiary university hospital in Portugal, along with inaugural procedures of their kind in Europe.

Delta-like ligand 3 (DLL3) landscape in pulmonary and extra-pulmonary neuroendocrine neoplasms.

Delta-like Ligand 3 (DLL3) targeting therapies are promising in small cell lung cancer (SCLC) treatment. However, DLL3 expression in SCLC and other neuroendocrine neoplasms (NEN) is heterogeneous and not well characterized. We describe the landscape of DLL3 at the mRNA and protein levels across SCLC, large cell neuroendocrine carcinoma (LCNEC), and non-small cell lung cancer.

Development of optimized standardized extracts of Echinodorus macrophyllus for arthritis management.

Ethnopharmacological Relevance: Echinodorus macrophyllus is a medicinal plant traditionally used in Brazil to treat rheumatic diseases. It is listed as a priority species for the development of herbal preparations for the Brazilian Unified Health System (SUS). Previous studies have demonstrated the anti-inflammatory and antiedematogenic properties of extracts and fractions from this species, but these preparations were neither standardized nor optimized for anti-arthritis effects.

Exploring biodegradable alternatives: microorganism-mediated plastic degradation and environmental policies for sustainable plastic management.

Plastics offer versatility, durability and low production costs, but they also pose environmental and health risks due to improper disposal, accumulation in water bodies, low recycling rates and temporal action that causes physicochemical changes in plastics and the release of toxic products to animal health and nature. Some microorganisms may play crucial roles in improving plastic waste management in the future. Cunningamella echinulata has been identified as a promising candidate that remains viable for long periods and produces a cutinase that is capable of degrading plastic.
