Researches as Malformations of cortical development in children with congenital cytomegalovirus infection - A study of nine children with proven congenital cytomegalovirus infection affirm that... “Congenital cytomegalovirus (CMV) infection is the most common vertically transmitted disease with the rate of the infection ranging from 0.2 to 2.4% in newborn infants”.
A chemical remedy had already been experimented inOral Hexadecyloxypropyl-Cidofovir Therapy in Pregnant Guinea Pigs Improves Outcome in the Congenital Model of Cytomegalovirus Infectionas an alternative orally supply analog of the existing drug, Cidofovir, against CMV
125 pregnant women tested, IgG antibody was found 84% (105 women) of the times, but IgM only on 7.2% (9 women)It means that they weren’t always present, signifying lack of antibody levels. Therefore, that can be reasoned that... (hypothesis)
Musmusculus, because:resemblance to human, able to be infected with CMV, more ethical to work with than humans, small sized, highly fertile, principally because isgraded as ideal for ‘in vivo’ hybridomasto produce continuous supply of antibody. Division:9 for each experimental group + 3 for the control group.Image Citometri = stores image data and the microscopic parameters describing the optics during the acquisition.
Dextran Leukocyte Separation Kit = isolation of the PMN by dextran separation PMN Polymorphonuclear leukocytes:CMV DNA can be detected in different fractions of leukocytes like this one during active infectionFormaldehyde-Noidet P-40=solution made of a simple Aldehyde and a detergent.MRI= Magnetic Resonance Image
Selective Optical Control of Synaptic Transmission in the Subcortical Visual Pathway by Activation of Viral Vector-Expressed Halorhodopsin.Anestethiaze with ketamineand xylazineInject mice with unilateral pressure injections of 1.0–1.5 µl of CMV vector solution (Recombinant CMV) into the body using a glass micropipette with a tip diameter of 20–30 µm.Place pipette for an 30 s and then slowly withdrawn.
IL 6 =B-cell stimulatory factorIL 28=inmune defense against virusIgG= battle bacterial and viral infectionsIgM= first reponse against antigen presenceEach will be for a complete of period fifteen days, because the sampling can be made days before the offspring born.
After fifteen days of gestation, the CVS (Chronic Villous Sampling) in order to analyze the placenta tissue. Placenta is the organ where the mother supplies the fetus important needs for the development as nutritional and respiratory.
