Extracellular circulating miRNAs as stress-related signature to search and rescue dogs

This research explores serum extracellular circulating miRNAs (ecmiRNAs) involved in dog stress response immediately after the search and rescue (SAR) of missing people and reveals a functional role of let-7a andLet-7f in the p53 pathway to restore cellular homeostasis.

Hope for Ostomates: A Carbon and Zeolite Impregnated Polyester Fabric Inhibits Urine Odor in Cancer Patients: A Randomized Experimental Study

It is demonstrated that the carbon and zeolite containing polyester fabric did significantly interfere with the ability of the dogs to detect VOCs in urine of men with prostate cancer, and may show promise as a pouch cover in controlling offensive urine odor.

Metabolomics in the Diagnosis and Prognosis of COVID-19

Several metabolic pathways related to amino acid, lipid and energy metabolism were found to be affected by severe disease with COVID-19, suggesting the roles of several metabolites of this pathway such as tryptophan, kynurenine and 3-hydroxykynurenines as potential prognostic markers of the disease.

The Promise of Disease Detection Dogs in Pandemic Response: Lessons Learned From COVID-19

Evidence of disease detection dogs use in infectious and chronic diseases, the training, oversight, resources required, and potential uses in various settings are explored, and efforts are needed to ensure public and political support.

COVID‐19 sniffer dog experimental training: Which protocol and which implications for reliable sidentification?

This protocol could provide a useful tool for sniffer dogs' training and their introduction in a mass screening context, it could be cheaper and faster than a conventional testing method.

Biodetection dogs for COVID-19: an alternative diagnostic screening strategy

Diffusion Fails to Make a Stink

It is found that a purely diffusive model cannot simultaneously satisfy the tracking conditions when parameters are in the experimentally observed range, demonstrating the necessity of modelling odor dispersal with full fluid dynamics, where non-linear phenomena such as turbulence play a critical role.



Scent dog identification of samples from COVID-19 patients – a pilot study

Preliminary findings indicate that trained detection dogs can identify respiratory secretion samples from hospitalised and clinically diseased SARS-CoV-2 infected individuals by discriminating between samples from SATS infected patients and negative controls.

Detection dogs as a help in the detection of COVID-19 Can the dog alert on COVID-19 positive persons by sniffing axillary sweat samples ? Proof-of-concept study

There is a very high evidence that the armpits sweat odour of COVID-19+ persons is different, and that dogs can detect a person infected by the SARS-CoV-2 virus.

False-negative results of initial RT-PCR assays for COVID-19: A systematic review

The findings reinforce the need for repeated testing in patients with suspicion of SARS-Cov-2 infection given that up to 29% of patients could have an initial RT-PCR false-negative result.
