Abstract:
We studied the effectiveness of hydrogen peroxide in removing visible laser-induced photoluminescence from the Raman spectra of compact bone of mice. In testing various bone sample preparations, we found that hydrogen peroxide bleaching was most effective when applied directly to fresh or fresh-frozen bone samples. The extent of the reduction in photoluminescence in the peroxide-bleached bone was such that the Raman spectrum could be readily recorded with 532-nm laser excitation. A comparison of bone samples before and after hydrogen peroxide bleaching shows that the Raman shifts of all the collagen and bioapatite bands are unaffected by the peroxide bleach. Moreover, the low spectral backgrounds of the peroxide-treated bone samples permit the Raman spectra of these two major components of bone to be fully separated. The Raman spectrum of collagen-rich periosteum was subtracted from the Raman spectrum of compact bone, which isolated the Raman spectral signature of the bioapatite fraction of the bone. This derived spectrum of bioapatite was then used, through spectral subtraction, to generate the spectral signature of the collagen component of the bone. All the major and minor Raman bands of collagen and bioapatite can be identified in these separate spectra.

Abstract:
AbstractThe IR absorption spectra of subendothelial regions of the aortic valve cusps of a patient with calcified aortic stenosis diagnosis were measured by the attenuated total reflectance (ATR) spectroscopy technique in a frequency interval of 2500–3600 cm^–1 and analyzed in comparison to the spectra of healthy human tissues and reference spectra of a pig’s healthy bone and aortic valve. The IR absorption band structure in this spectral region was studied by means of expansion into Gaussian components. The energies of hydrogen bonds (H-bonds) involving O–H groups were estimated. It is established that, among all samples studied, the energy of H-bonds between hydroxyl groups reaches maximum in the bone tissue.

Abstract:
The Classical Least Square (CLS) fitting method was used to analyze the Raman spectra of living cells with the aim of identification of new phenotype-specific spectral markers for osteoblasts. The following chemicals were used for the CLS model: DNA, RNA, serum albumin, chymotrypsin and phosphatidyl choline. In this study we analyzed primary mature osteoblasts as well as two other cell types used as potential sources of osteoblasts: embryonic stem cells and fetal bone cells. The results obtained suggest that the Raman spectra of the cell types can be well approximated with a linear combination of the Raman spectra of the biopolymers used in the CLS model. The relative concentrations of the CLS components varied significantly between cell types, indicating that this analytical method could be used for phenotypic identification of osteoblasts.

Abstract:
By using photoacoustic (PA) spectroscopy it was performed a study about bone consolidation in fractures. It was obtained the optical absorption spectra of callus of male rat fractured bones at different consolidation times. From these spectra it was possible to observe the presence of alkaline phosphatase through their absorption peaks which were compared with characteristic peaks reported in the literature for this phosphatase. In this study we showed that alkaline phosphatase could be considered as an indicator of the repair process of bone fractures.

Abstract:
In this study, the feasibility of assessing the chemical composition in bone using the multi-wavelength photoacoustic analysis (MWPA) method was investigated. By illuminating a bone specimen using laser light with a wavelength tunable over an optical spectrum from 680 nm to 950 nm, the optical absorption spectrum of the bone was acquired. Then, with the optical absorption spectra of all the optically absorbing chemical components in the bone known, a spectral unmixing procedure was performed to quantitatively assess the relative content of each chemical component. The experimental results from porcine rib bones demonstrated that the contents of the chemical components, including not only non-organic materials such as minerals and water but also organic materials including oxygenated hemoglobin, deoxygenated hemoglobin, lipid, and collagen, can all be assessed by MWPA. As the chemical composition in the bone is directly associated with functional and metabolic activities, the finding from this study suggests that the MWPA method could offer a new diagnostic tool for the non-invasive evaluation of bone health.

Abstract:
Abstract The mineral content of stationary bone samples can be quantified by 31P nuclear magnetic resonance (NMR) spectroscopy. The assay can be performed in regions of the anatomy that pose problems for absorptiometric techniques, because the mineral content is measured within a selected volume without concern for the geometry of the bone. In vivo 31P NMR spectra of the bones in human fingers and wrist are reported. Soft tissue such as marrow and skeletal muscle contributes little to the 31P NMR spectra of human fingers and wrist and thus should not seriously affect the accuracy of the mineral assay. 31P NMR spectrometry should prove helpful for confirming rapid bone mineral loss in those at risk and for monitoring response to treatment.

Abstract. X-ray absorption near edge structure (XANES) studies on calcium phosphate species (Ca-P) deal with marginal differences among subtle spectral features despite a hitherto missing systematic breakdown of these differences. Related fingerprinting approaches depend, therefore, on spectral libraries that are not validated against each other, incomplete and scattered among publications. This study compiled a comprehensive spectral library from published reference compound libraries in order to establish more clear-cut criteria for Ca-P determination by distinctive phosphorus K-edge XANES features. A specifically developed normalization method identified diagnostic spectral features in the compiled library, e.g. by uniform calculation of ratios between white-line and secondary peak heights. Post-processing of the spectra (n = 81) verified distinguishability among most but not all phases, which included hydroxylapatite (HAP), poorly crystalline HAP, amorphous HAP, fluorapatite, carbonate fluorapatite (CFAP), carbonate hydroxylapatite, β-tricalcium phosphate, octacalcium phosphate (OCP), brushite, monetite, monocalcium phosphate, amorphous calcium phosphate (ACP), anapaite, herderite, scholzite, messelite, whiteite and P on CaCO3. Particularly, peak-height ratios significantly improved analyte specificity, e.g. by supplementary breakdown into OCP and ACP. The spectral analysis also revealed Ca-P standards that were rarely investigated or inappropriately synthesized, and thus provides a basis for standard selection and synthesis. The method developed and resulting breakdown by species were subsequently tested on Ca-P spectra from studies on bone and sediment. The test indicated that bone material likely comprises only poorly crystalline apatite, which confirms direct nucleation of apatite in bone. This biological apatite formation is likely opposed to that of sedimentary apatite, which apparently forms by both direct nucleation and successive crystallization. Application of the method to μXANES spectra of sediment particles indicated authigenic apatite formation by an OCP precursor.

Abstract:
The work presented in this thesis revolves around spectral inequalities and their applications in quantum mechanics. In Paper A, the ground state energy of an atom confined to two dimensions is analyzed in the limit when the charge of the nucleus Z becomes very large. The main result is a two-term asymptotic expansion of the ground state energy in terms of Z. Paper B deals with Hardy inequalities for the kinetic energy of a particle in the presence of an external magnetic field. If the magnetic field has a non-trivial radial component, we show that Hardy’s classical lower bound can be improved by an extra term depending on the magnetic field. In Paper C we study interacting Bose gases and prove Lieb-Thirring type estimates for several types of interaction potentials, such as the hard-sphere interaction in three dimensions, the hard-disk interaction in two dimensions as well as homogeneous potentials.

Abstract:
The release of No Time To Die in 2021 heralds the arrival of the twenty-fifth installment in the James Bond film series. Since the release of Dr. No in 1962, the cinematic James Bond has expedited the transformation of Ian Fleming's literary creation into an icon of western popular culture that has captivated audiences across the globe by transcending barriers of ideology, nation, empire, gender, race, ethnicity, and generation. The Cultural Life of James Bond: Specters of 007 untangles the seemingly perpetual allure of the Bond phenomenon by looking at the non-canonical texts and contexts that encompass the cultural life of James Bond. Chronicling the evolution of the British secret agent over half a century of political, social, and cultural permutations, the fifteen chapters examine the Bond-brand beyond the film series and across media platforms while understanding these ancillary texts and contexts as sites of negotiation with the Eon franchise.

Abstract:
AbstractFibro-osseous lesions have posed a diagnostic dilemma since the beginning when the first case was reported in the late nineteenth century. Since then, various lesions are included in this group, yet the understanding of the lesions remains obscure for the clinician/surgeon. The main reason for this is their histological resemblance with one another, where they all show varying degrees of healthy bone replaced by fibrous tissue and some amount of bone/cementum-like tissue intermingled in between. This chapter is written with the aim of simplifying these groups of bony lesions for its readers and highlighting the key idea of interdisciplinary approach in the management of these lesions where the oral pathologist along with radiologist and clinician plays a pivotal role in differentially diagnosing these lesions, for the maxillofacial surgeon to choose and perform her/his duty of managing them, rightfully, for their patients. The spectrum of these lesions has seen several changes during the course of history yet there is still ample scope for ambiguity in identification and classification of the lesions, hence the authors have chosen few most commonly encountered lesions in the Indian subcontinent, for the description and discussion.

Abstract:
Dentin and bone are formed when odontoblasts and osteoblasts synthesize and secrete collagen type I-rich extracellular matrix that mineralizes in a highly controlled manner. A wide spectrum of mouse and human disorders affecting tooth and bone biomineralization shows that dentin and bone formation are under strict genetic control. Although the controlling mechanisms of dentinogenesis and osteogenesis require further study, a large body of evidence points to the importance of the matrix metalloproteinases (MMPs) participate in a wide variety of extracellular matrix degradation. Detailed knowledge of MMPs may be important for understanding the pathogenesis of tooth development. Some researchers have pointed MMP-9 is an extracelluar proteinase that is highly expressed in osteoclasts and has been postulated to play an important role in their resorptive activity. Although MMP-9 has been reported to play a role in bone resorption, the association of this enzyme during deciduous tooth resorption has not yet been clarified. Based on accumulating evidence, we hypothesized that MMP-9 should play a role in teeth attrition. In this study, we have applied NMR relaxation technique to assess age-related MMP-9 KO tooth quality in vitro by quantifying changes in dentin and pulp simultaneously. The major hypothesis in this paper was that whether noninvasive NMR relaxation time measurements could be used to characterize MMP-9 KO changes in dentin and pulp, and to predict tooth quality. Specifically, we tested that age-related MMP-9 KO tooth changes result in an alteration of the NMR spin-spin (T2) relaxation time signal due to the structural changes in the tooth matrix. This signal can be further processed to produce a T2 relaxation distribution spectrum related to dentin and pulp, and their derived parameters can be used as descriptors of age-related MMP-9 KO tooth changes. In this study, the proton liquid-like NMR spin-spin (T2) relaxation decay signal was obtained from the Carr-Purcell-Meiboom-Gill (CPMG) NMR spin echo train method [1,2], then the relaxation decay signal was converted to T2 relaxation distribution spectra describing the size domain of dentin and pulp. Therefore, we can calibrate the intensities in NMR inversion T2 relaxation distribution spectra corresponding to the amount of dentin and pulp related to the structural changes. Here, we propose an NMR calibration method “NMR standard estimation” — the ratio of the amount of pulp to the amount of dentin obtained from NMR T2 distribution spectra that can be used to measure the age-related MMP-9 KO structural changes in teeth [3]. We are cognizant of the biological and physiological variability manifest in teeth size variations, but feel that this kind of NMR standard estimation — the ratio of amount of dentin to amount of pulp from the NMR T2 inversion spectrum can be used to determine age-related MMP-9 KO structural changes in teeth and eliminate any variations in size of teeth.

Abstract:
Compared to other contemporarily used non-destructive evaluation (NDE) techniques, resonance inspection (RI), which employs the natural vibrational frequency spectra shift induced by the damage to detect defects, is advantageous in many aspects such as low cost, high testing speed, and broad applicability to complex structures. However, the inability to provide damage details, i.e. location, dimension, or types, of the flaws severely hinders its wide spread applications and further development despite its early success in the automobile industry for quality inspections of safety critical parts. In this study, an inverse RI algorithm using a maximum correlation function as the filtering function is proposed to quantify the location and size of flaws for a discrepant part. The algorithm and the numerical schemes are validated using a dog-bone shaped stainless steel sample, while the spectrum data for the original part and flawed parts were generated by a commercial FEM package. The results show that multiple flaws can be accurately identified using the proposed RI inversion method. The study further showed that the reliability of the inversion method is sensitive to the spectrum range included in the correlation function computation. It is demonstrated that the frequency range required to provide accurate predictions is inversely correlated to the defect size. Large defects can be detected using lower frequency spectrum data only, while smaller defects require a higher frequency range.

Abstract:
The techniques of low-field pulsed proton nuclear magnetic resonance (NMR) spin relaxation and Micro-CT are described for assessment of structural changes of human cortical and trabecular bone in vitro. The technique involves spin-spin relaxation measurement and inversion spin-spin spectral analysis methods for NMR. From NMR measurement, the CPMG T2 relaxation data can be inverted to T2 relaxation distribution and this distribution then can be transformed to a pore size distribution with the longer relaxation times corresponding to larger pores. In Micro-CT measurement, each trabecular bone specimen was individually scanned using a micro-computed tomography (micro-CT) system and 12 micron dimensionally-isotropic voxels were reconstructed. Due to the resolution limitation, Micro-CT measurement on cortical bone was not success, however, NMR measurement was success for both cortical and trabecular bones.
