A geometric morphometric approach to identify uncomplete snake vertebrae from raptor bird feeding remains
<p>The Hungarian meadow viper (<em>Vipera ursinii rakosiensis</em>) is an endangered subspecies of <em>Vipera ursinii</em>, which faces high predation pressure, partially due to avian species. To create a systematic method for estimating the measure of predation pressure, we developed a geometric morphometric approach to identify both undamaged and damaged vertebrae of snake species found in Hungarian meadow viper habitats from raptor feeding remains. We used linear discriminant analysis with a reference material of vertebrae from identified snake species as training data. We also tested its efficiency by predicting the identification results of different simulation levels based on vertebra completeness. We practiced this method on vertebrae of unknown species of snakes obtained from nests and pellets of short-toed snake eagles (<em>Circaetus gallicus</em>, n=9), common buzzards (<em>Buteo buteo</em>, n=14) and Montagu’s harriers (<em>Circus pygargus</em>, n=3). The identification approach showed high accuracy, even in the case of missing landmarks to some extent. We identified vertebrae remnants of <em>Natrix natrix</em> (n=172, 83.9%), <em>Coronella austriaca</em> (n=10, 4.9%) and <em>V. u. rakosiensis</em> (n=23, 11.2%). Both, the reptile specialist <em>C. gallicus</em> and<em> </em>the generalist<em> B. buteo</em> proved to be preying on <em>V. u. rakosiensis</em>, while samples of <em>C. pygargus</em> did not contain any snake remains despite of previous observations of <em>V. ursinii</em> predations. Our approach is applicable for other studies and taxa as well, therefore can be a practical tool for classification of incomplete vertebrae, which is otherwise hardly identifiable. Furthermore, it could be applied to help estimate predation pressure on endangered snake species.</p>

Segmented lordotic angles to assess lumbosacral transitional vertebra on EOS
<p><strong>Purpose: </strong>To test the vertical posterior vertebral angles (VPVA) of the most caudal lumbar segments measured on EOS to identify and classify the lumbosacral transitional vertebra (LSTV).</p> <p><strong>Methods: </strong>We reviewed the EOS examinations of 906 patients to measure the VPVA at the most caudal lumbar segment (cVPVA) and at the immediately proximal segment (pVPVA), with dVPVA being the result of their difference. Mann-Whitney, Chi-square, and ROC curve statistics were used.</p> <p><strong>Results: </strong>172/906 patients (19%) had LSTV (112 females, mean age: 43 ± 21 years), and 89/172 had type I LSTV (52%), 42/172 type II (24%), 33/172 type III (19%), and 8/172 type IV (5%). The cVPVA and dVPVA in non-articulated patients were significantly higher than those of patients with LSTV, patients with only accessory articulations, and patients with only bony fusion (all p < .001). The cVPVA and dVPVA in L5 sacralization were significantly higher than in S1 lumbarization (p < .001). The following optimal cutoff was found: cVPVA of 28.2° (AUC = 0.797) and dVPVA of 11.1° (AUC = 0.782) to identify LSTV; cVPVA of 28.2° (AUC = 0.665) and dVPVA of 8° (AUC = 0.718) to identify type II LSTV; cVPVA of 25.5° (AUC = 0.797) and dVPVA of - 7.5° (AUC = 0.831) to identify type III-IV LSTV; cVPVA of 20.4° (AUC = 0.693) and dVPVA of - 1.8° (AUC = 0.665) to differentiate type II from III-IV LSTV; cVPVA of 17.9° (AUC = 0.741) and dVPVA of - 4.5° (AUC = 0.774) to differentiate L5 sacralization from S1 lumbarization.</p> <p><strong>Conclusion: </strong>The cVPVA and dVPVA measured on EOS showed good diagnostic performance to identify LSTV, to correctly classify it, and to differentiate L5 sacralization from S1 lumbarization.</p>

Chemical evidence of preserved collagen in a 54-million-year-old fish vertebrae
<p>Collagens are the most abundant protein in the animal kingdom. <span>Collagens form </span><span>the structural framework of connective tissues such as bones, tendons and skin and play important biomechanical role in supporting tissue functions. The preservation of collagen in deep time is a topic of intense debate. Here we provide </span>indisputable evidence of the presence of collagen in Early Eocene fish vertebrae using online pyrolysis-comprehensive two dimensional gas chromatography-time-of-flight mass spectrometry and immunofluorescence studies. The presence of cyclic dipeptides such as <span>diketodipyrrole, </span>2,5-diketopiperazine of proline-proline and 2,5-diketopiperazine of proline-glycine along with other nitrogen-bearing molecules in the pyrolysis products of the studied fossils unequivocally demonstrate that collagen can withstand degradation and diagenetic alteration. Immunofluorescence study also confirms the presence of collagen-I in the fossilized fish vertebrae. The present findings suggest, contrary to common opinion, that the preservation of collagen in fossilized soft tissues is not rare. We propose that one of the essential factors controlling preservation of collagen is the establishment of a suitable microenvironment within the fossil inhibiting diagenetic alteration including microbial decay.</p>
