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...

We have demonstrated recombination of bacteriophage T7 DNA in vitro. An extract of Escherichia coli B cells infected with wild-type T7(T7+) is incubated with mature DNA extracted from T7 phage. Packaging of the exogenous DNA within the phage head appears to be preceded by recombination of exogenously added DNA with DNA present in the extracts. In order to detect the recombination, we used an ex...

BACKGROUND Hepatocellular carcinoma (HCC) is a common malignancy in Egypt due to the high frequency of hepatitis C virus (HCV) infection among the general population. Circulating free DNA is a potential molecular marker for the diagnosis and prognosis of malignant tumors. DNA released from apoptotic cells usually consists of short uniform fragments while DNA released from cancer cells is longer...

The molecular variability of ten genotypes of Celosia argentea seeds collected from National Institute of Horticultural Research (NIHORT) and National Centre for Genetic Resources and Biotechnology (NACGRAB) germplasms were evaluated using the Amplified Fragment Length Polymorphism (AFLP) marker. The polymorphism of C. argentea was detected within the population using primer mix of AFLP EcoRI +...

background : hepatitis includes a wide range of clinical and pathological conditions. the beta-2 microglobulin (ãÿ2m), as part of thehla complex, is responsible for transmission of viral antigens on the surface of liver cells. the purpose of this study is to determine the concentration of salivary ãÿ2m as a marker of viral proliferation in subjects who are hbsag + , hbv dna pcr + compared with ...

Cell-free DNA has emerged as the most reliable, non-invasive prenatal screening tool for fetal aneuploidies. It come to replace previously widely used quadruple screen offered in second trimester of pregnancy. This change comes with improved detection aneuploidy but also presents potential gaps diagnosis including open defects and emerging data on prediction adverse pregnancy outcomes. review a...

Genetic diversity is a study undertaken to classify an individual or population compared to other individuals or populations. This is a relative measure, as the distance between any pair of entries in the study is greater or lesser depending on all pairwise comparisons that can be made in the study. However, genetic fingerprinting is the unambiguous identification of an individual (based on the...
