“…Previous studies have shown that numerous factors affect antler growth and properties (reviewed by Landete-Castillejos et al 2012). For our comparative study it was necessary to have similar conditions throughout the study (e.g.…”

Antlers are costly structures produced annually by male cervids using minerals obtained from their diet and from resorption of their skeleton. Availability and nutritive quality of food resources therefore have a great impact on the investment of males in these secondary sexual traits. We studied the structure, mineral composition and mechanical quality of antlers of the Siberian wapiti (Cervus canadensis sibiricus), Père David's deer (Elaphurus davidianus) and Vietnamese sika deer (Cervus nippon pseudaxis), three closely-related cervid species. The three herds investigated were maintained under the same feeding and management conditions (one male per herd) throughout a 3-year study period. We showed that there was no significant inter-specific difference in antler composition of the three species under the same feeding regime. However, mechanical properties varied between the Siberian wapiti and the other two species; and structural characteristics were different among all of them. Our results show that antler composition has a similar chemical profile across species when grown under the same feeding regime whereas the internal structure and mechanical properties appear to be species dependent.

“…El caso del potasio es un buen ejemplo de cómo un enfoque multidisciplinar, en donde participan profesionales de varias disciplinas, puede ayudar a producir hallazgos inesperados. Así, en un estudio en donde colaboraron ecólogos y expertos en anatomía patológica (Landete-Castillejos et al 2012a), se demostró que el potasio se encuentra en el andamiaje sobre el que crecen las osteonas, de modo que abunda más cuanto menos desarrolladas están éstas; y al madurar el tejido dicho andamiaje es sustituido parcialmente (Fig. 4).…”

For our study we can summarize that potential differences in photon migration properties between bulla and metacarpal are likely, to a large extent, attributable to differences in their mineralization while for the more porous antler bone the lower mineralization may not be the only contributing factor.…”

“…Firstly, the intensity of the bone phosphate band at 961 cm −1 divided by the intensity of the CH 2 deformation band at 1450 cm −1 (mineralization ratio), and secondly the intensity ratio of the bone phosphate band at 961 cm −1 to the bone carbonate band at 1071 cm −1 (carbonate substitution) were calculated. For comparison, also the density and porosity values of the bone specimens were compiled from the literature [30][31][32][33] and all results are shown in Table 1. As expected, 28 the bones showed pronounced differences with respect to their mineralization ratio and the antler had the lowest value.…”

The ability of Spatially Offset Raman Spectroscopy (SORS) to obtain chemically specific information from below the sample surface makes it a promising technique for non-invasive in vivo diagnosis of bone conditions by sampling bone through the skin. The depth below a surface interrogated by SORS depends on the system's optical properties and is difficult to estimate for complex bone material. This paper uses 830 nm laser excitation to investigate the influence of bone mineralization on photon migration properties in deer antler cortex, equine metacarpal cortex and whale tympanic bulla. Thin slices form each type of bone (thickness: 0.6-1.0 mm) were cut and put together on top of each other forming stacks with a total thickness of 4.1-4.7 mm. A 0.38 mm thin slice of polytetrafluoroethylene (PTFE) served as a test material for Raman signal recovery and was placed in between the individual bone slices within the stack. At SORS offsets of 8.0-9.5 mm Raman bands of materials not present in healthy bone (e.g. PTFE as an example) can be recovered through 4.4-4.7 mm of cortical bone tissue, depending on mineralization level and porosity. These findings significantly increase our understanding of SORS analysis through bones of different composition and provide information that is vital to determine the value of SORS as a medical diagnostic technique. The data serve to define which SORS offset is best deployed for the non-invasive detection of chemically specific markers associated with infection, degeneration and disease or cancer within bone.
