“…TEM varied from 0.39 (C4) to 1.51 (S4), and rTEM from 0.38% (S1) to 4.45% (C5) in the interobserver assessment. As expected, inter-observer error was greater than the intra-observer error, 48,58 and the clavicular measurements were relatively more prone to errors.…”

The estimation of biological sex is a critical step in the assessment of the biological profile of an anonymous skeletonized individual. In certain recovery circumstances, the most dimorphic skeletal areas, such as the pelvis, are absent or fragmented; in that case, other bones of the skeleton, including the clavicle and scapula, can be used to predict sex. The purpose of this research is to generate new models for the estimation of sex with clavicular and scapular measurements using a study-sample of 129 individuals with clavicle (65 males and 64 females) and 112 individuals with scapula (50 males and 62 females) from the Lisbon Identified Skeletal Collection (Portugal). A decision tree classifier (C4.5) and logistic regression (LR) were employed to create univariable and multivariable sex prediction models. Accuracy under cross-validation of the classification models is high (up to 93.8%), with minimal bias (<5%), particularly in the multivariable models. The proposed LR models facilitate the probabilistic estimation of biological sex, accounting for the significant overlap in the expression of sexual dimorphism.

“…Analysis of the XRD patterns of B-raw, HA-700, and HA-1000 samples was performed in the range 2 θ = 10°–80° with a step size of 0.05°. The standard diffraction data of the Joint Committee on Powder Diffraction Standards (JCPDS) reference 00-009-0432 for the HA phase was used for phase identification 28 , while the crystallite size ( X c , nm) of the HA samples was calculated using Scherrer’s equation: 29 where k is a constant equal to 0.9, λ is the X-ray wavelength (1.54 Å), β is the full width at half maximum (FWHM, radians), and θ is the diffraction angle of the reflection plane at [002].…”

“…A hand-held X-ray fluorescence (XRF) analyzer (Delta Premium, Olympus, Waltham, MA, USA), which can detect elements from 12 Mg through 83 Bi, was used to quantify elemental composition of B-raw buffalo femur bone, as previously described 23 , 27 – 29 . The XRF was calibrated with a standard reference material before any measurements were made, and quality control was monitored using software 28 .…”

Hydroxyapatite (HA) can be used in odontology and orthopedic grafts to restore damaged bone due to its stable chemical characteristics, composition, and crystal structural affinity for human bone. A three-step hydrothermal method was used for the extraction of biogenic calcined HA from the buffalo waste bones at 700 °C (HA-700) and 1000 °C (HA-1000). Extracts were analyzed by thermogravimetric analysis, differential scanning calorimetry, X-ray fluorescence, X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and in vivo examination of HA xenografts for femoral lesions in experimental rats. Crystallinity, purity, and morphology patterns showed that the HA main phase purity was 84.68% for HA-700 and 88.99% for HA-1000. Spherical HA nanoparticles were present for calcined HA-700 samples in the range 57–423 nm. Rats with critical bone lesions of 3 mm in diameter in the left femur treated with calcined HA-700 nanoparticles healed significantly (p < 0.001) faster than rats treated with HA-1000 or negative controls. These findings showed that spherical biogenic HA-700 NPs with a bud-like structure have the potential to stimulate both osteoconduction and bone remodeling, leading to greater bone formation potential in vivo. Thus, the calcined biogenic HA generated from buffalo waste bones may be a practical tool for biomedical applications.
