Revista Latino-Americana de Enfermagem, 2008 This study aims to present reflections on the meaning of olfactory sensations and perceptions, as well as their relevance as a phenomenon present in Nursing practice. It stresses the importance of the smells' chemical language in the hospital environment,

The mereological theory of odors
, 2020 We propose the mereological theory of odors, according to which odors are proper parts of concrete objects. We distinguish between object solid core and gaseous periphery; the odor is the periphery and plays a role in olfactory perception similar to the ...

Pest Responses to Odors From Predators Fed a Diet of Target Species Conspecifics and Heterospecifics
, 2010 Research into the use of predator-odor-based repellents as a management tool has gained momentum during the past 30 years. Some studies have suggested that odors from a predator whose diet includes the target species are more effective than odors from a ...

Flies Avoid Current Atmospheric CO2 Concentrations
Frontiers in Physiology, 2021 CO2 differs from most other odors by being ubiquitously present in the air animals inhale. CO2 levels of the atmosphere, however, are subject to change. Depending on the landscape, temperature, and time of the year, CO2 levels can change even on shortest

Forensic Science International, 2012 This study, the third of a series on the odor signature of human decomposition, reports on the intermittent nature of chemical evolution from decomposing human remains, and focuses primarily on headspace analysis from soil associated with older human remains (10-60+ years) from different environments around the globe. Fifty grams of soil were collected

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Weight Status and Attentional Biases Toward Foods: Impact of Implicit Olfactory Priming
Frontiers in Psychology, 2019 Objective: Numerous studies highlight the involvement of cognitive factors in the development and maintenance of obesity. We aimed to measure attentional biases (AB) toward foods (i.e., the individual tendency to automatically orient one’s attention ...

Do fecal odors from native and non‐native predators cause a habitat shift among macropods?
, 2015 Predator-odor-based repellents have benefits as humane, non-lethal management tools that may reduce the need for lethal control in some areas. Macropods (such as kangaroos and wallabies) are iconic Australian native marsupials; however, some are ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.
