Diagnosis by the smell of insects – healing practice

Breakthrough in cancer diagnosis achieved

It will be in the near future Diagnosis of insect cancer in humans? The latest research results suggest this, because it was possible with the help of the insect’s sense of smell and a special sensor different types of oral cancer to identify.

In a recent study by the experts of the Michigan State University investigated whether locusts can identify different types of cancer based on their sense of smell. The results can be found on the English language prepress server for life sciences “BioRxiv”.

Diagnosis of diseases by animals

In the past, animals were trained to detect certain diseases in humans. For example, dogs can smell cancer or COVID-19.

Can insects smell cancer?

Now there is one new approach to cancer diagnosis from insects. A so-called VOC sensor based on the neural circuit of the sense of smell of insects.

Evidence of cancer in the exhaled air

That the Metabolic processes in cancer cells are impairedit has already been clearly demonstrated, according to the researchers. This is reflected in the composition of the volatile organic compounds (VOC) in the exhaled air of those affected.

The researchers built a new VOC sensor for which an in vivo insect brain was initially combined with an electrophysiology platform. With this
For this, from the Composition of volatile organic compounds of individual cell cultures triggered neural olfactory reactions in the so-called Tarpaulins for antennas analyzed, an area of ​​the brain in insects.

Insects have smelled three types of oral cancer

On the one hand, it was possible three different types of cancer of the human oral cavity reliably distinguished from each other. On the other hand, the use of the sensor also allowed the three types of cancer to be one distinguish non-cancerous oral cell lineaccording to the team.

Oral cancer classification works reliably

By evaluating VOC-induced neuronal responses of cancer and non-cancer, we demonstrate that oral cancer classification based on olfactory neuron response is sensitive and reliable.‘the researchers report.

It took 250 ms to detect the cancer

Another benefit is this brain-based approach to identify cancer leads to results very quicklywith just the detection time according to the researchers 250 ms lies.

The team also showed that the new cancer diagnosis method is effective in changing chemical environments imitate natural conditions.

Our brain-based cancer detection system incorporates a new VOC detection method that will fuel the development of other advanced technologies for non-invasive cancer detection‘summarized the experts. (how)
