Isolation of genomic DNA is one of the basic steps in many different molecular analyses. There are a few reports on methods of DNA isolation from milk, but many of them are time consuming and expensive, and require relatively large volumes of raw milk. In this study a rapid, sensitive, and efficient method of DNA extraction from milk somatic cells of various mammals (cattle, sheep, goats, horses) is presented. It was found that milk is a good source of genomic DNA, and to obtain a sufficient amount and quality of DNA, suitable for molecular analysis such as PCR, 10 mL of raw milk is sufficient. Thanks to this method, stress in animals can be reduced during collection of researched material. Therefore, this method could be widely used in molecular analyses.

Background: The usefulness of circulating free DNA (cfDNA), nuclear DNA (nDNA) and mitochondrial DNA (mtDNA) as potential biomarkers in cancer remains controversial.
Objective: To determine the concentration of cfDNA and plasma nDNA and mtDNA levels in breast cancer (BC) patients.
Material And Methods: This study included a total of 86 women (69 patients with BC and 17 women as a control group).

Chloramphenicol (CAP) is widely used in treating bacteria infection in animals and humans. However, the accumulation of CAP in food and environment caused serious health risk to human. Consequently, sensitive and selective detection of CAP is of great importance in environmental monitoring and food safety.

Purpose: A first-in-human phase one study was conducted in nasopharyngeal carcinoma (NPC) patients to assess the safety and tolerability of VK-2019, a small molecule selective inhibitor of Epstein-Barr virus Nuclear Antigen 1 (EBNA1).
Patients And Methods: Pharmacokinetic and pharmacodynamic studies, including circulating tumor EBV DNA plasma levels, were performed. Twenty-three patients received VK-2019 orally once daily at doses ranging from 60 to 1800 mg using an accelerated titration design, with cohort expansion at 1800 mg.

Background: Skeletal dysplasia (SD) represents a series of highly heterogeneous congenital genetic diseases affecting the human skeletal system. Refined genetic diagnosis is helpful for the accurate diagnosis and prognosis evaluation of SDs.
Materials And Methods: In this study, we recruited 26 cases of SD and analyzed them with a designed sequential genetic detection.

The association between late replication timing and low transcription rates in eukaryotic heterochromatin is well known, yet the specific mechanisms underlying this link remain uncertain. In , the histone deacetylase Sir2 is required for both transcriptional silencing and late replication at the repetitive ribosomal DNA (rDNA) arrays. We have previously reported that in the absence of , a de-repressed RNA PolII repositions MCM replicative helicases from their loading site at the ribosomal origin, where they abut well-positioned, high-occupancy nucleosomes, to an adjacent region with lower nucleosome occupancy.
