Silicone Oil-Functionalized Hydrophobic Nano Silica: A Floating Sorbent for Organic Pollutant Removal in Aquatic Systems.

Meso/microporous nano silica modified with macromolecular polymers produces attractive hybrids that repel water and have a hydrophobic surface, making them highly effective for targeting and eliminating organic contaminants in aquatic environments. In this study, nano silica was functionalized with silicone oil, an oligomeric siloxane derivative, to produce a hydrophobic silica nano hybrid characterized by a non-wetting water contact angle of 139°. This hydrophobic hybrid nano silica showed a sustainable floating nature on water even in turbulent streams.

Molecular cloning and heterologous expression of lipase gene from Pseudomonas aeruginosa in Escherichia coli.

Lipases, enzymes that perform the hydrolysis of triglycerides into fatty acids and glycerol, present a potential paradigm shift in the realms of food and detergent industries. Their enhanced efficiency, energy conservation and environmentally friendly attributes make them promising substitutes for chemical catalysts. Motivated by this prospect, this present study was targeted on the heterologous expression of a lipase gene, employing E.

Fluoride Induces Toxic Effects on the A549 Pulmonary Cell Line at Non-cytotoxic Concentrations.

Fluoride is emitted into the air not only through gas emissions but also from volcanic ash, leading to contact via inhalation. Therefore, the objective of the present study was to evaluate the cellular and biochemical responses in the A549 cell line after exposure to NaF (sodium fluoride) concentrations lower than those previously used in other studies to determine the impact on the lung epithelium. A549 cells were exposed to different concentrations (0.

Outcomes of Minimally Invasive Rectal Cancer Resection: Insights From a Resource-Limited Setting.

Background: Minimally invasive approaches for rectal cancer treatment are emerging as the standard of care. Robotic surgery is unfeasible across the country due to constrained resource allocation. This study aimed to assess the oncologic efficacy of laparoscopic resection for rectal cancer in a resource-limited setting.

Advances in diagnosis and prognosis of bacteraemia, bloodstream infection, and sepsis using machine learning: A comprehensive living literature review.

Background: Blood-related infections are a significant concern in healthcare. They can lead to serious medical complications and even death if not promptly diagnosed and treated. Throughout time, medical research has sought to identify clinical factors and strategies to improve the management of these conditions.
