The forensic application of mitochondrial DNA (mtDNA) typing requires large and regionally well-defined databases. To expand the database for forensic identification purposes in Slovenia, the mtDNA control region sequences of the hypervariable regions HVI and HVII were determined in a population of 129 maternally unrelated Slovenians, using a fluorescent-based capillary electrophoresis sequencing method. A total of 111 different haplotypes resulting from 124 polymorphic positions (80 polymorphic positions in HVI and 44 in HVII) were found. Of these, 101 mtDNA types were unique, 6 haplotypes were shared by 2 individuals, 1 haplotype by 3 individuals, 2 haplotypes by 4 individuals, and the most common haplotype was found in 5 individuals. The most frequent haplotypes in the Slovenian population,263(G), 315.1(C) and 263(G), 309.1(C), 315.1(C) are also the most common in other European populations. The data support the concept that these haplotypes may represent a common European mtDNA sequence types. The sequence poymorphisms were compared to the databases of west Austria and central Italy and the HVI and HVII sequence matching probabilities within and between populations were calculated. It is 1.1-4.5 times more likely to find a sequence match in a random pair of Slovenians than in a random Slovenian-Italian pair and in a random Slovenian-Austrian pair. The length heteroplasmy in the homopolymeric C-stretch regions located at nucleotide positions 16184-16193 in HVI and at positions 303-315 in HVII was observed in 17% and 8% of individuals, respectively. A statistical estimate of the results for this population showed the random match probability and the genetic diversity of 1.16% and 0.996, respectively.
Measures of the predictive accuracy of regression models quantify the extent to which covariates determine an individual outcome. Explained variation measures the relative gains in predictive accuracy when prediction based on covariates replaces unconditional prediction. A unified concept of predictive accuracy and explained variation based on the absolute prediction error is presented for models with continuous, binary, polytomous and survival outcomes. The measures are given both in a model-based formulation and in a formulation directly contrasting observed and expected outcomes. Various aspects of application are demonstrated by examples from three forms of regression models. It is emphasized that the likely degree of absolute or relative predictive accuracy often is low even if there are highly significant and relatively strong covariates.
The Austrian Professor Erich Ruttin was appointed as the director of the Ear, Nose and Throat Department of Istanbul University at the beginning of September 1934. Leaving behind the directorship of the Ear, Nose and Throat Clinic of Rudolfspital in Wien, Ruttin no doubt tried to leave Austria due to the beginning of anti-semitic influences of the Nazi regime in Germany, which had lead him to sign a contract with the Istanbul University for a period of ten years. It is remarkable that despite this contract he stayed only one year in Turkey. This article presents his contributions in the field of otorhinolaryngology during his short stay in Turkey and explains the background of his early departure.
