2013
A whole-body nanoparticle aerosol inhalation exposure facility was constructed for nano-sized titanium dioxide (TiO2) inhalation toxicology studies. This system provides nano-TiO2 aerosol test atmospheres that have: 1) a steady mass concentration; 2) a homogenous composition free of contaminants; and 3) a stable particle size distribution during aerosol generation.

2018
Determining the fungal diversity within an environment is a method utilized in occupational health studies to identify health hazards. This protocol describes DNA extraction from occupational air samples for amplification and sequencing of fungal ITS regions. This approach detects many fungal species that can be overlooked by traditional assessment methods.

Methods to Investigate the Regulatory Role of Small RNAs and Ribosomal Occupancy of Plasmodium falciparum
0 Views •
2015
Human microRNAs translocate from host erythrocytes to Plasmodium falciparum parasites. Here, the techniques used to transfect synthetic microRNAs into host erythrocytes and isolate all RNAs from P. falciparum are described. In addition, this paper will detail a method of polysome isolation in P. falciparum to determine the ribosomal occupancy and translational potential of parasite transcripts.

In the current climate of scarce resources, new technologies are emerging that allow researchers to conduct studies cheaper, faster and with more precision. Here we describe the development of a bead-based salivary antibody multiplex immunoassay to measure human exposure to multiple environmental pathogens simultaneously.
FAQs
These factors determine how clinicians judge the significance of a workplace contact. Inhalation, skin or eye contact, ingestion, injection, and physical energy represent different routes, while intensity or dose and duration describe the exposure burden. Worker susceptibility adds individual context, helping clinicians prioritize evaluation, medical surveillance, and preventive measures.
A hazard’s potential effect depends not only on its category but also on how contact occurs and how much or how long the worker is exposed. Chemical, biological, physical, and ergonomic hazards may therefore require different assessment considerations. Identifying the hazard together with its route and exposure conditions supports more appropriate clinical interpretation.
A focused exposure history organizes the details needed to connect a health concern with workplace conditions. Clinicians can document the suspected hazard, route, intensity or dose, duration, and relevant worker susceptibility. This information supports recognition of work-related disease or injury and helps determine whether medical surveillance or post-exposure evaluation is appropriate.
Workplace controls and personal protective equipment provide prevention strategies after potential hazards have been identified. Controls address conditions in the work environment, while protective equipment helps limit worker contact with hazards. Applying these measures alongside exposure assessment can reduce risks to healthcare workers and support safer clinical care for patients.
Clinicians should consider workplace exposure when an injury, infection, illness, or other health effect may be related to work conditions. Reviewing the person’s occupational contact can reveal a relevant hazard and exposure pathway that might otherwise be missed. This perspective supports recognition of work-related disease, prevention planning, and timely post-exposure evaluation.
Medical surveillance provides an organized way to monitor workers in relation to occupational hazards, while post-exposure evaluation addresses a known or suspected contact in a timely manner. Together, they extend beyond identifying the hazard by supporting clinical follow-up, prevention decisions, and safer practices for workers and the patients they serve.
