This focal point article discusses the developments of biomedical Raman and infrared spectroscopy, and the recent strive towards being a recognised clinical tool for various applications. The promise of vibrational spectroscopy in the field of biomedical science, alongside the development of computational methods for spectral analysis, has driven a plethora of proof-of-concept studies which convey the potential of various spectroscopic approaches. Here we report a brief review of the literature published over the past few decades, with a focus on the current technical, clinical and economic barriers to translation, namely the limitations of many of these early studies, the lack of understanding of clinical pathways, health technology assessments, regulatory approval, clinical feasibility and funding applications. The field of biomedical vibrational spectroscopy must acknowledge and overcome these hurdles in order to achieve clinical efficacy. Current prospects have been overviewed with comment on the advised future direction of spectroscopic technologies, with the aspiration that many of these innovative approaches can ultimately reach the frontier of medical diagnostics and other clinical applications.

Thousands of people from more than eighty countries have traveled to China since 2001 to undergo fetal cell transplantation. Galvanized by the potential of stem and fetal cells to regenerate damaged neurons and restore lost bodily functions, people grappling with paralysis and neurodegenerative disorders have ignored the warnings of doctors and scientists back home in order to stake their futures on a Chinese experiment. This book looks at why and how these individuals have entrusted their lives to Chinese neurosurgeons operating at the forefront of experimental medicine, in a world where technologies and risks move faster than laws can keep pace. The book shows how cutting-edge medicine is not just about the latest advances in biomedical science but also encompasses transformations in online patient activism, surgical intervention, and borderline experiments in health care bureaucracy. The book opens up important theoretical and methodological horizons in the anthropology of science, technology, and medicine. It illuminates how poignant journeys in search of fetal cell cures become tangled in complex webs of digital mediation, the entrepreneurial logics of postsocialist medicine, and fraught debates about the ethics of clinical experimentation. Using innovative methods to track the border-crossing quests of Chinese clinicians and their patients from around the world, the book maps the transnational life of fetal cell therapies.

The present paper is interested in the study of compounds from the apatite family with the general formula Ca10 (PO4)6A2. It particularly brings to light the exploitation of the distinctive stereochemistries of two Ca positions in apatite. In fact, Gd-Bearing oxyapatiteCa8 Gd2 (PO4)6O2 has been synthesized by solid state reaction and characterized by X-ray powder diffraction. The site occupancies of substituents is0.3333 in Gd and 0.3333 for Ca in the Ca(1) position and 0. 5 for Gd in the Ca (2) position.  Besides, the observed frequencies in the Raman and infrared spectra were explained and discussed on the basis of unit-cell group analyses.
