Green Sol-Gel Synthesis of Iron Oxide Nanoparticles for Magnetic Hyperthermia Applications.

Background/objectives: The unique properties of iron oxide nanoparticles have attracted significant interest within the biomedical community, particularly for magnetic hyperthermia applications. Various synthesis methods have been developed to optimize these nanoparticles.

Methods: In this study, we employed a powdered coconut water (PCW)-assisted sol-gel method to produce magnetite nanoparticles for the first time.

Propagation of a Fatigue Crack Through a Hole.

The stop-hole technique is a well-known strategy to extend the fatigue life of cracked components. The ability to estimate fatigue life after the hole is important for safety reasons. The objective here is to develop strategies for the accurate prediction of initiation and propagation life ahead of the stop-hole.

Flies as Carriers of Gastrointestinal Protozoa of Interest in Public Health in the Northeast of Brazil.

Purpouse: This study aimed to assess the influence of the presence of synanthropic flies in food preparation environments on the transmission of potentially zoonotic gastrointestinal protozoa.

Methods: Flies were captured using a glass containing water, fruits, and pieces of protein.

Results: Approximately 260 flies from four different species were captured: Musca domestica (76.

Robotic Versus Thoracoscopic Minimally Invasive Mitral Valve Surgery: A Systematic Review and Meta-Analysis of Matched Studies.

Mitral regurgitation is the most prevalent form of valvular heart disease, impacting over 24 million people globally. Robotic and thoracoscopic minimally invasive mitral valve repair (MIMR) techniques have emerged as viable alternatives to traditional open-heart surgery. However, the comparative effectiveness and safety of these 2 approaches remain underexplored.

Proposals of indigenous peoples and local communities from Brazil for multilateral benefit-sharing from digital sequence information.

One of the main themes of the 16th Conference of the Parties to the Convention on Biological Diversity is Digital Sequence Information (DSI): genomic or related data deposited in publicly accessible databases in a digital language. These sequences are important for research in areas such as biodiversity conservation and bioprospecting. Some characteristics of organisms that stimulate the commercial use of biodiversity may have been developed by Indigenous Peoples and Local Communities, and therefore, they have associated traditional knowledge.
