(e.g. EDX) and empirical analyses, and with the help of the knowledge that the authors have about the biochemistry of the human body’s metabolic
activities, those structures can be assigned to a range of metabolic
processes (Figure 2). The energy-dispersive X-ray

The method
begins with the thermal disintegration of the blood sample. For that purpose the specimen is denatured into very small carbon chains and peroxides with the help of a standardised method. In the course of the subsequent
resuspension of the particles obtained, the small carbon chains can repolymerise and the electrolytes crystallise in a solid shape around the polymer structures previously formed. Their size is recorded using in-process control. The polymer solution is transferred to
object slides and therefore prepared for evaluation. The polymers are precipitated in the form of complexes by dehydrogenation. The resulting structures are analysed using
microscopy and electron microscopy, and then digitally documented (Figure 1). Through electron microscopic techniques, radiological measurements

spectroscopy (EDX) is a measuring method coming from materials analytics. This is a method belonging to X-ray spectroscopy. The atoms of the sample are stimulated by an electron beam of consistent energy. They then emit X-ray radiation with an energy that is specific for the individual element, so-called characteristic X-rays. This radiation provides information about the sample’s element composition. The allocation and evaluation of the structures obtained is accomplished using existing clinically-achieved
and endoscopic findings. Colonoscopy The endoscopic examination of the intestines
with flexible devices has been widely used as a safe method for a number of years. During colonoscopy the physician can view and evaluate the whole colon with an endoscope. Further to this evaluation, the examination allows the physician to take tissue samples from affected areas, and even to perform small operations. The examination hardly causes any pain. However, if requested, it can also be carried out under slightly sedative medication.
Preparation It is paramount to optimally cleanse the intestines before a colonoscopy. Only after all stool residues are irrigated completely can the examiner effectively recognise changes in the intestinal mucosa. Preparations were made according to the applicable guidelines21, 22
