Population Genetic Data of 30 Insertion-Deletion Markers in the Polish Population.

(1) Background: Insertion-deletion (InDel) markers show the advantages of both short tandem repeats (STRs) and single nucleotide polymorphisms (SNPs) and are considered alternative markers in forensic genetics. (2) Methods: Allelic frequencies and corresponding forensic efficiency parameters of 30 autosomal polymorphic InDel loci included in the Investigator DIPplex kit (Qiagen) were obtained in a sample of 631 unrelated Polish individuals. Allelic frequency data were compared with those reported for selected populations (3) Results: All the loci conformed with Hardy-Weinberg equilibrium after applying a Bonferroni correction and no pair-wise significant linkage disequilibrium was detected.

The rs2228145 polymorphism in the interleukin-6 receptor and its association with long-term prognosis after myocardial infarction in a pilot study.

Introduction: Interleukin-6 (IL-6) is a cytokine with a complex function that is described as both pro- and anti-inflammatory. One factor that influences its function is the rs2228145 A/C single nucleotide polymorphism (SNP) of the IL-6 receptor (IL6R) gene. C allele carriers have a decreased inflammatory response and decreased prevalence of ischemic heart disease.

The 9p21 polymorphism is linked with atrial fibrillation during acute phase of ST-segment elevation myocardial infarction.

The aim of the study was to find whether patients carrying polymorphic allele of the rs10757278 polymorphism from 9p21 locus have changed risk of arrhythmia (atrial fibrillation, AF; sustained ventricular tachycardia or ventricular fibrillation, sVT/VF) during acute phase of myocardial infarction. Retrospective analysis of data collected prospectively from two independent centers was performed. The clinical data were pooled from two independent cardiac registries: (1) the Warsaw ACS genetic registry (STEMI and NSTEMI/UA patients hospitalized in the years 2008-2011; only STEMI patients were analyzed); (2) the Bialystok STEMI genetic registry (STEMI patients hospitalized in years 2001-2005, who survived the first 48 h from hospital admission).

Typeability of DNA in Touch Traces Deposited on Paper and Optical Data Discs.

Background: Nucleated epithelial cells that are transferred by casual touching and handling of objects are the primary source of biological evidence that is found in high-volume crimes. Cellular material associated with touch traces usually contains low levels of DNA template making it challenging to acquire an informative profile.

Objectives: The main purpose of this study was to examine the efficacy of DNA typing in fingerprints deposited on optical data discs and the office paper.

Fatal drowning as a result of an airplane crash--case report.

An ULM (Ultra Light Motorized) plane Aeroprakt 22-L with two men on board dived unexpectedly into the Dworackie lake near the town of Olecko in Warmia and Mazury district, Northeastern Poland. The pilot and the passenger had multiorgan blunt injuries, including subdural and subarachnoid hemorrhage, fractured ribs, fractured thigh (in one of the deceased) and pulmonary contusions as a result of the impact with the lake. The multiorgan injuries and unconsciousness resulting from head trauma prevented the casualties from saving themselves.
