Environmental and biological measurements of the anesthetic isoflurane and its possible toxic effects in veterinarians.

We evaluated both environmental (workplace) and biological (urine) exposure to the anesthetic isoflurane concerning the effects of such exposure on the hematological, hepatic, and renal parameters in veterinarians. Samples were collected from exposed and nonexposed (volunteers) groups to assess hematological and several biochemical markers, and isoflurane was measured in the workplace air and veterinarian's urine. Isoflurane was detected at high levels in the air and urine.

From indoors to outdoors: Impact of waste anesthetic gases on occupationally exposed professionals and related environmental hazards - A narrative review and update.

Waste anesthetic gases (WAGs) are trace-concentration inhaled anesthetics that exist worldwide because they are released into the ambient air of operating rooms (ORs) and post-anesthesia care units. WAGs cause indoor contamination, especially in ORs lacking proper scavenging systems, and occupational exposure, while promoting climate change through greenhouse gas/ozone-depleting effects. Despite these controversial features, WAGs continue to pose occupational health hazards.

Genetic instability of a single exposure to sevoflurane at different concentrations in monitored mice.

Sevoflurane is an inhalation anesthetic widely used for general anesthesia, but its genotoxic potential is controversial in clinical studies. It is unknown whether the effects are due to surgery or the anesthetic. Thus, for the first time, the present study investigated genotoxicity in peripheral blood cells and in target organs (liver, lung, and kidney) and micronucleus (MN) in the bone marrow of a single exposure to sevoflurane at three different concentrations in monitored mice.

Microstate Analyses to Study face Processing in Healthy Individuals and Psychiatric Disorders: A Review of ERP Findings.

Microstates represent brief periods of quasi-stable electroencephalography (EEG) scalp topography, offering insights into dynamic fluctuations in event-related potential (ERP) topographies. Despite this, there is a lack of a comprehensive systematic overview of microstate findings concerning cognitive face processing. This review aims to summarize ERP findings on face processing using microstate analyses and assess their effectiveness in characterizing face-related neural representations.

Virulent shiga toxin-producing Escherichia coli (STEC) O157:H7 ST11 isolated from ground beef in Brazil.

In this study, a total of 248 ground beef samples were analyzed for the presence of Shiga toxin-producing Escherichia coli (STEC). Out of these samples, only one (0.4%) tested positive for STEC.
