“…These studies were based on the property that skin fluoresces under ultraviolet light, 17 (Figure 8A). Interestingly, it was noted that similar to what was recently found with blood serum, 16 the fluorescence intensity of mouse tails increased after a brief exposure to heat (Figure 8A). Initially, the importance of moisture was examined, with dry mouse tails added to filter paper that was dry or very slightly dampened (see Materials and Methods for details).…”

The mechanism for creation of the faint ventral and dorsal images of a man on the Shroud of Turin is unknown. It has been suggested that image formation involves oxidation and dehydration of the cellulose present in the linen, or, alternatively, that a superficial residue on the surface of the cloth is responsible for creating colored products through the Maillard reaction. One of the major criticisms of the latter hypothesis is that gaseous diffusion is not sufficient to result in the detailed bodily structures present on the cloth. Recently, it was proposed that additional substrates might also participate in the Maillard reaction, specifically proteins and amino acids present in skin, helping to increase the detail of any image produced. Understanding more fully the properties of the Shroud image is important for the preservation of this cloth for future generations. In the current report the potential contribution of skin proteins and amino acids in the Maillard hypothesis of image formation was evaluated. Using a variety of systems, these data show that detailed imaging of skin imprints may be obtained through contact transfer and interaction with reducing sugars. These results importantly extend the scope of this hypothesis and provide additional, relevant information concerning possible mechanisms for the formation of the Shroud of Turin image.

Ultraviolet fluorescent detection of elevated bilirubin in dried blood serum

Increased levels of bilirubin in blood serum may result from numerous physical conditions including hepatitis, cirrhosis, enzyme deficiency, drug reactions, autoimmune disorders and physiological trauma. No presumptive test for high bilirubin levels in blood serum stains currently exists, which could prove useful in the assessment of crime scenes involving victims with one of the above disorders. Here, the use of ultraviolet 365 (UV 365) is described as a simple, nondestructive method for the detection of blood serum containing elevated levels of bilirubin.

The Effect of Humidity on Blood Serum Pattern Formation and Blood Transfer

A detailed knowledge of the drying properties of blood is important for a more complete understanding of the forensic information that may exist at a crime location. Although the effect of relative humidity on the general properties of blood drying has been evaluated, relatively little information exists regarding the alterations of blood serum distribution that may occur during the drying process. Moreover, the influence of humidity on the ability of dried blood drops to transfer from skin to absorbent material has never been studied. The data in the current report show that blood serum pattern formation is distinctly altered by increased humidity in drying drops of blood. In addition, these data document that high humidity conditions were sufficient to remoisten dried blood drops such that they were able to transfer to the absorbent material, with the original bloodstain pattern maintained.
