Biomechanical properties of the human tibia: fracture behavior and morphology [see comments]

Rabl,W.; Haid,C.; Krismer,M.; Standardized biomechanical dynamic load tests were performed to obtain fundamental information on the fracture behavior and morphology of the human tibia. After preparation, the specimens (n = 32) were loaded to breakage by ventral (one side alternately), dorsal, medial or lateral loading on a servo-hydraulic testing machine (Walter und Bai, Lohningen, Switzerland). Primary and secondary fracture lines and fissures were marked differently on the three surfaces of the tibia specimens. [Read More]

Cardiac troponin I in the diagnosis of myocardial injury and infarction

Mair,J.; Genser,N.; Morandell,D.; Maier,J.; Mair,P.; Lechleitner,P.; Calzolari,C.; Larue,C.; Ambach,E.; Dienstl,F.; Pau,B.; Puschendorf,B.; We used a cardiospecific enzymoimmunometric assay to measure cardiac troponin I (cTnI) in samples serially drawn from 78 patients with acute myocardial infarction (AMI), 7 patients with unstable angina (Braunwald class III), 22 multi-traumatized patients, and in 30 athletes after eccentric exercise, as well as in 101 non-traumatic chest pain patients on admission to the emergency department. cTnI assay crossreactivity with crude human skeletal muscle homogenates was < 0.

Fatal posture- and heroin-related intestinal infarction and leg muscle necrosis after snorting heroin. A case report

Rabl,W.; Markwalder,C.; We present a case of a male patient who spent several hours sitting with legs crossed and upper body bent forward after nasal insufflation of heroin (snorting). Death occurred 3 days later as a result of leg muscle necrosis and intestinal ileus with infarction. The autopsy findings, including microthrombi in small mesenteric vessels and necrosis of the leg muscles, were attributed to vascular compression due to the man’s position and to metabolic processes resulting from drug ingestion [Read More]

HLA-DQ alpha genotype and allele frequencies in an Austrian population

Ambach,E.; Zehethofer,K.; Scheithauer,R.; The HLA-DQ alpha system is used to an increasing degree in forensic serology, for stain investigations, and paternity cases. Therefore samples which were taken from 85 unrelated persons living in Austria were examined. DNA was analyzed by polymerase chain reaction (PCR) amplification followed by hybridization to allele-specific oligonucleotide probes in a reversed dot-blot technique after extraction with phenol/chloroform. HLA-DQ alpha allele frequencies of German, Finnish, Dutch, British, Italian, Caucasian/USA and of Austrian populations were compared. [Read More]
