“…Molybdenum is also very important for the normal metabolism of life as a necessary trace element of organisms . Furthermore, recent studies showed that molybdenum may be related to the growth of bone and tooth . Therefore, it may be very promising to investigate the molybdenum‐doped BGNs (Mo‐BGNs) as a bioactive material for regulating osteogenic differentiation of ADSCs.…”

Adipose‐derived stem cells (ADSCs) are considered to be ideal stem cell sources for bone‐tissue regeneration owing to their ease of collection and high activity. However, the regulation of osteogenic differentiation of ADSCs using biomaterials without adding growth factors is still not satisfactory. For the first time, molybdenum‐doped bioactive glass nanoparticles with a radial porous morphology (Mo‐rBGNs) are reported and their role in the osteogenic differentiation of ADSCs is investigated. The results show that Mo‐rBGNs exhibit radially porous and spherical morphology, relatively homogeneous particle size (200–400 nm), and excellent apatite‐forming bioactivity. They do not affect the proliferation of ADSCs, but significantly regulate their osteogenic differentiation and biomineralization. 5% Mo‐rBGNs significantly enhance the alkaline phosphatase activity and biomineralization ability and promote the osteogenic gene expressions of collagen I secretion and bone sialo protein in ADSCs. A reasonable and promising strategy for designing nanoscale bioactive materials with the excellent osteogenic ability for stem cell–based bone tissue regeneration is provided.

“…bones, teeth, soft tissues or body fluids) of a particular mammal species has been studied for a wide range of purposes, such as tissue structure1314, the role of elements in physiology151617, contamination by environmental pollution1819, and forensic science202122232425. Many techniques are used for element detection, such as inductively coupled plasma mass spectrometry (ICP-MS)26, atomic absorption spectroscopy (ASS)27 and X-ray fluorescence (XRF)2829; each technique has both advantages and disadvantages.…”

“…All samples used in this study were under the authority of museums or belonged to private owners who did not allow any destruction of the samples. HH-XRF has been shown to be an appropriate technique for detection of elements in animal tissues such as horn/antler24, bone212431 or teeth/tusks222325 for either biological or forensic purposes. For example, analysis of elemental data by discriminant analysis and logistic regression models has been successful in identifying the origin of elephant tusks, i.e.…”

In addition, analysis of the elemental composition by stepwise discriminant analysis could correctly discriminate between human and non-human teeth22.

“…molecular methods, including polymerase chain reaction (PCR) and sequencing that have been used for species identification3233 and sex determination of dugongs and other species3435 – they are time-consuming, expensive and require considerable technical expertise and laboratory facilities. Elemental analysis by HH-XRF is not only less time-consuming, but also does not involve destruction of the sample (invasive technique); moreover, no laboratory work is required, making it suitable for primary screening in a field study prior to further assessment by a more advanced technique22232529.…”

The elemental composition was investigated and applied for identifying the sex and habitat of dugongs, in addition to distinguishing dugong tusks and teeth from other animal wildlife materials such as Asian elephant (Elephas maximus) tusks and tiger (Panthera tigris tigris) canine teeth. A total of 43 dugong tusks, 60 dugong teeth, 40 dolphin teeth, 1 whale tooth, 40 Asian elephant tusks and 20 tiger canine teeth were included in the study. Elemental analyses were conducted using a handheld X-ray fluorescence analyzer (HH-XRF). There was no significant difference in the elemental composition of male and female dugong tusks, whereas the overall accuracy for identifying habitat (the Andaman Sea and the Gulf of Thailand) was high (88.1%). Dolphin teeth were able to be correctly predicted 100% of the time. Furthermore, we demonstrated a discrepancy in elemental composition among dugong tusks, Asian elephant tusks and tiger canine teeth, and provided a high correct prediction rate among these species of 98.2%. Here, we demonstrate the feasible use of HH-XRF for preliminary species classification and habitat determination prior to using more advanced techniques such as molecular biology.

The focus of this work is a comprehensive overview of analytical techniques for elemental and isotopic analyses applied in forensic science (i.e. linking crime scene evidence to a crime by applying analytical techniques). The article provides a short description of the spectroscopic techniques and an overview of selected applications. In addition to general forensics, applications in nuclear forensics, environmental forensics, and food forensics are covered. Selected applications are linked to reviews and selected publications, which should allow for an overview of the current approaches in forensic analytical chemistry. This is an update article of its first version published in 2014 by Prohaska and Draxler. 1
