Unplanned extubation (UPE), defined as accidental removal of the endotracheal tube during mechanical ventilation or its replacement due to suspected obstruction or inadequate diameter, is considered the fourth most common adverse event in neonatal intensive care units (NICU). This study aimed to describe a systematic review and meta-analysis protocol that will identify and assess the effect of primary intervention measures designed to prevent UPE in NICU. A search will be carried out in the following databases: PubMed/Medline, EMBASE, Scopus, CINAHL, Cochrane Library, SciELO, and LILACS.

Copper is a vital trace element crucial for mediating interactions between and macrophages. Within these immune cells, copper modulates oxidative stress responses and signaling pathways, enhancing macrophage immune functions and facilitating clearance. Conversely, copper may promote escape from macrophages through various mechanisms: inhibiting macrophage activity, diminishing phagocytic and bactericidal capacities, and supporting survival and proliferation.

The enterobacterium present in the human gut can reduce trimethylamine N-oxide (TMAO) to trimethylamine during anaerobic respiration. The TMAO reductase TorA is a monomeric, bis-molybdopterin guanine dinucleotide (bis-MGD) cofactor-containing enzyme that belongs to the dimethyl sulfoxide reductase family of molybdoenzymes. TorA is anchored to the membrane via TorC, a pentahemic -type cytochrome which receives the electrons from the menaquinol pool.

The extracellular matrix (ECM) is a complex structure involved in many biological processes with collagen being the most abundant protein. Density of collagen fibers in the matrix is a factor influencing cell motility and migration speed. In cancer, this affects the ability of cells to migrate and invade distant tissues which is relevant for designing new therapies.

Article Synopsis
- Autophagy is vital for cellular balance and responds to different stimuli, but there's limited understanding of how it works under energy deprivation.
- Researchers are focused on how cells detect energy shortages and start autophagy, using various model organisms and mammalian cells.
- Key factors involved in this process include reactive oxygen species (ROS), the DNA damage sensor Mec1, and mitochondrial aerobic respiration.
