The study of ante-mortem trauma is a popular and important aspect of palaeopathological analysis. The majority of publications focus on a particular assemblage, skeletal element or type of fracture, with case studies of single individuals with multiple/unusual traumata being much rarer in the literature. This paper presents the case of an adult male from the Bronze Age site of Sharakhalsun, Russia, buried, uniquely, in a sitting position on a fully assembled wagon, who displayed evidence for multiple healed ante-mortem fractures of the cranium, axial and appendicular skeleton. The mechanisms and likely etiologies of the fractures are presented, with reference to modern and 19th century clinical literature, and possible interpretations suggested: that the individual was involved in a severe accident involving a wagon or draft animals, or both, a number of years before his death. The suggestion is also made that the unique burial position of the individual was a form of commemoration by the community of the survival and recovery of the individual from such a serious incident. 相似文献

Evaluation of H2O2 and pH in exhaled breath condensate samples: methodical and physiological aspects
This veterinary study is aimed at further standardization of H2O2 and pH measurements in exhaled breath condensate (EBC). Data obtained in the study provide valuable information for many mammalian species including humans, and may help to avoid general pitfalls in interpretation of EBC data. EBC was sampled via the 'ECoScreen' in healthy calves (body weight 63-98 kg). Serum samples and condensates of ambient (indoor) air were collected in parallel. In the study on H2O2, concentrations of H2O2 in EBC, blood and ambient air were determined with the biosensor system 'ECoCheck'. In EBC, the concentration of H2O2 was found to be dependent on food intake and increased significantly in the course of the day. Physiologically, lowest H2O2 concentrations at 06:00 varied within the range 138-624 nmol l-1 EBC or 0.10-0.94 nmol per 100 l exhaled breath and individual concentrations were significantly different indicating a remarkable intersubject variability. Highly reproducible results were seen within each subject (three different days within 4 weeks). No correlation existed between H2O2 concentrations in EBC and blood, and EBC-H2O2 was not influenced by variables of spontaneous breathing. Further results confirmed that standardization of H2O2 measurements in EBC requires (1) the re-calculation of the concentration exhaled per 100 l exhaled breath (because the analyzed concentration in the liquid condensate underlies multiple methodological sources of variability given by the collection process), and (2) subtracting the concentration of inspired indoor H2O2. In the study on pH use of the ISFET electrode (Sentron, the Netherlands) and a blood gas analyzer ABL 550 (Radiometer, Denmark) led to comparable results for EBC-pH (r=0.89, R2=79.3%, p≤0.001). Physiological pH data in non-degassed EBC samples varied between 5.3 and 6.5, and were not significantly different between subjects, but were significantly higher in the evening compared with the morning. EBC-pH was not dependent on variables of spontaneous breathing pattern or ambient conditions, and no significant correlation was found between serum and EBC for pH. 相似文献

Two cloned fucosyltransferases, Fuc-t III and Fuc-t VI, are probed on a preparative scale with non-natural donor-substrates, in which the guanosine of the natural donor guanosine-diphosphate-fucose is replaced by other purines. Surprisingly, the novel purine-diphosphate-fucoses (PDP-Fuc) are recognized by both enzymes as donor-substrates. 相似文献

When experimental tumours are inoculated into a host animal, the tumour growth depends, among other things, on its vascular supply. This vascular supply has been shown to be initiated by substances released by the tumour tissue, and vascular sprouting towards implanted tumour substances has been extensively demonstrated in nonvascular tissue. Most tissues, however, already contain a vascular supply sufficient for their own needs. In such conditions, the host vascular system is probably incorporated into the tumour without much vascular sprouting. It is well known that, as a tumour grows larger, the center tends to become ischaemic and necrotic. It is not clear why the tumour vascularity does not respond to this development with reactive vascular proliferation, but increased interstitial tissue pressure and impaired fluid transport may be implicated. 相似文献
