Background: The success of in vitro-fertilization (IVF) cycles is determined large part by the quality embryo cleavage, which turn, dependent on culture media (CM). Many factors can influence CM, one levels Cell Free Deoxyribonucleic acid (DNA). Understanding association between Cell-free DNA CM and cleavage could help improve IVF techniques.
 Methods: This prospective study was conducted ...

Reactive oxygen species (ROS)plays an important role in sperm motility. The physiological generation at low concentration induces beneficial effects on sperm functions and plays a significant role in sperm metabolism. Meanwhile, the excessive generation of reactive oxygen species can overwhelm protective mechanism and triggers changes in lipid and protein layers of sperm plasma membrane, which ...

Background: Endometriosis is one of the most common benign gynecological diseases which is characterized by endometriallike tissue growing outside the uterine cavity. Although the pathology of endometriosis remains unknown, the genetic predisposition plays an apparent role. Several genes have been contributed to endometriosis, but it seems KRAS has a crucial role, because its activation results...

Abstract Objectives Free DNA is used as a cancer biomarker due to its low cost, high applicability, and fast, reliable results compared invasive methods. This study aimed evaluate the quantification of plasma-free after long-term storage conditions perform qualification through single nucleotide polymorphism (SNP) screening based on this DNA. Methods Plasma-free samples were quickly isolated fr...

We separate double stranded lambda phage DNA by applying a fixed force at a constant temperature ranging from 15 to 50 degrees C, and measure the minimum force required to separate the two strands. The measurements also offer information on the free energy of double stranded DNA (dsDNA) at temperatures where dsDNA does not thermally denature in the absence of force. While parts of the phase dia...

The aim of this work is to present the experimental results in form an algorithm for analyzing modification screen printed electrodes, including possibility its regeneration irreversibly oxidizing biologically active compounds (drugs, DNA and proteins). A protocol was developed quantitative analysis study mechanism drug-DNA interaction by differential pulse voltammetry, following parameters: co...
