DNA isolated from formalin-fixed paraffin-embedded healthy tissue after 30 years of storage can be used for forensic studies.

Tissue formalin fixation and paraffin embedding (FFPE) is a standard method for long-term preservation and morphological and molecular analysis. The aim of this study was to analyze the effect of storage time on the integrity of DNA isolated from three different healthy FFPE tissues. DNA was isolated from FFPE heart, liver and brain tissues obtained from autopsy and archived from 1988 to 2017 using two different methods of DNA isolation: phenol-chloroform-isoamyl alcohol (PCI) and PureLink Genomic DNA Kit.

Genetic variant rs16944 in IL1B gene is a risk factor for early-onset sepsis susceptibility and outcome in preterm infants.

Objective: Interleukin-1-B (IL1B) is a proinflammatory cytokine that plays an important role in sepsis. The aim of this study was to evaluate the relationships between IL1B-511G/A polymorphism and susceptibility and outcome of early-onset sepsis (EOS) in preterm infants.

Methods: DNA was extracted from the buccal swabs of 471 (285 with EOS and 186 control) preterm infants.

Association between Tumor Necrosis Factor-α Promoter -308 G/A Polymorphism and Early Onset Sepsis in Preterm Infants.

Early-onset neonatal sepsis (EOS) is diagnosed during the first 7 days of neonatal life and is the major cause of morbidity and mortality among preterm infants. Genetic predisposition may have an impact on EOS susceptibility and outcome. The aim of our study was to explore the association between TNF-α -308 G/A or IL-6 -174 G/C gene polymorphism and the susceptibility and outcome of EOS in preterm infants.

Subtelomeric screening in Serbian children with dysmorphic features and unexplained developmental delay/intellectual disabilities.

Developmental delay and intellectual disabilities (DD/ID) are significant health problems affecting 3% of the human population. Submicroscopic chromosomal rearrangements involving subtelomeric regions are often considered to be the cause of unexplained DD/ID. Screening of subtelomeric regions was performed in 80 unrelated patients with DD/ID and normal GTG-banded chromosomes using the MLPA method with two kits (SALSA P070-B1 and P036-E1).

Divergent patrilineal signals in three Roma populations.

Previous studies have revealed that the European Roma share close genetic, linguistic and cultural similarities with Indian populations despite their disparate geographical locations and divergent demographic histories. In this study, we report for the first time Y-chromosome distributions in three Roma collections residing in Belgrade, Vojvodina and Kosovo. Eighty-eight Y-chromosomes were typed for 14 SNPs and 17 STRs.

Human Y-chromosome short tandem repeats: a tale of acculturation and migrations as mechanisms for the diffusion of agriculture in the Balkan Peninsula.

Southeastern Europe and, particularly, the Balkan Peninsula are especially useful when studying the mechanisms responsible for generating the current distribution of Paleolithic and Neolithic genetic signals observed throughout Europe. In this study, 404 individuals from Montenegro and 179 individuals from Serbia were typed for 17 Y-STR loci and compared across 9 Y-STR loci to geographically targeted previously published collections to ascertain the phylogenetic relationships of populations within the Balkan Peninsula and beyond. We aim to provide information on whether groups in the region represent an amalgamation of Paleolithic and Neolithic genetic substrata, or whether acculturation has played a critical role in the spread of agriculture.
