An Efficient Method For DNA Extraction From Paraffin Wax Embedded Tissues For PCR Amplification Of Human And Viral DNA

  Background and Objective: Formalin-fixed paraffin-embedded tissues are a valuable source of DNA for molecular studies. We designed and optimized an efficient procedure for DNA extraction from formalin-fixed paraffin embedded tissues. Materials and Methods: Seventy three blocks of cervical paraffin-embedded tissues were investigated. DNA was extracted using 45 minutes boiling in alkaline sol...

Blood groups: In Health and Diseases

ABO blood type antigens are polymorphic, inherited structures presented on the surface of red blood cells. Although ABO blood group antigens is the most important antigens in transfusion medicine, its main role is not clearly clarified. Correlation between ABO blood group and susceptibility to certain infectious and non-infectious diseases is a controversial issue. Since, lack of blood type ant...

I-6: Remodelling Uterine Spiral Arteries inPregnancy

Background: During the first trimester of pregnancy the uterine spiral arteries that supply blood to the placenta are remodelled, creating heavily dilated conduits lacking maternal vasomotor control. To effect permanent vasodilatation, the internal elastic lamina and medial elastic fibres must be degraded. Failure of remodelling is a key characteristic of the pathological placenta and is though...

Production and functional characterization of human insulin-like growth factor 1

Insulin-like growth factor 1 (IGF-1) is a polypeptide hormone produced mainly by the liver in response to the endocrine growth hormone (GH) stimulus. This protein is involved in a wide range of cellular functions, including cellular differentiation, transformation, apoptosis suppression, migration and cell-cycle progression and other metabolic processes. In the current study, human heart cDNA w...

Radioadaptive Response in Human Lymphocyte Cells

The adaptive response (AR) is a phenomenon by which cells exposure to sublethal doses of DNA-damaging agents (non-mutagenic dose of chemical or radiation), known as conditioning treatment (CT), leads to increased resistance to a subsequent exposure to a higher dose of the same or other agents, known as challenge treatment (CR). The adaptive response (AR) induced by radiation in human lymphocyte...
