Chromosomal abnormalities in sperm higher after vasectomy reversal
Men who have had a vasectomy reversed have a very much greater rate of chromosomal abnormalities in their sperm than do normal fertile men, a scientist told the 22nd annual conference of the European Society of Human Reproduction and Embryology in Prague, Czech Republic on Wednesday 21 June 2006. Professor Nares Sukchareon, of the Department of Obstetrics and Gynaecology, Chulalongkorn Universi...Speeding the search for elusive chromosomal errors
A pediatric research team has used commercially available gene chips to scrutinize all of a patient's chromosomes to identify small defects that cause genetic diseases. Because currently used genetic tests usually cannot detect these abnormalities, the new research may lead to more accurate diagnosis of congenital diseases, including puzzling disorders that lead to mental retardation. "For...What controls stickiness of 'smart' chromosomal glue
Researchers have a new understanding of the process cells use to ensure that sperm and eggs begin life with exactly one copy of each chromosome ?a process that must be exquisitely regulated to prevent problems such as miscarriages and mental retardation. The new work reveals how gluelike protein complexes release pairs of chromosomes at precisely the moment of meiosis ?the specialized cell divisi...Chromosomal microarray analysis proves accurate
Two years and more than 2,000 samples after researchers at Baylor College of Medicine started to use a new gene-chip technology called chromosomal microarray analysis to look for potential genetic abnormalities in children, they find that it is remarkably sensitive in detecting abnormalities in individual chromosomes, according to a report that appears online today in the journal Public Library o...Chromosomal Grade Agarose from Bio-Rad
Description:Chromosomal Grade Agarose was developed specifically for pulsed field separations of DNA larger than 2 megabase pairs. This agarose has the highest gel strength of any electrophoresis agarose available, allowing preparation of very low percentage agarose gels. Megabase DNA separations done in Chromosomal Grade...Chromosomal Grade Agarose from Bio-Rad

According to a new study, researchers, suggest that, some women who develop gestational diabetes during pregnancy may be prone to have children with certain chromosomal abnormalities However, researchers stress, gestational diabetes is not itself a risk factor for these types of defects since they form in the early stages of pregnancy--well before gestational diabetes typically develops.// <br...Test for prenatal chromosomal abnormalities using cervical swab
Australian researchers have discovered a new method to test for prenatal chromosomal// abnormalities using cervical swabs. Testing fetus for chromosomal abnormalities are currently done through amniocentesis and other methods of screenings. In their new research, the scientists have been able to isolate single cells of the fetus from the cervical mucus of the pregnant woman with the he...Prenatal exposure to air pollution causes chromosomal damage
Pregnant mothers who are constantly exposed to air pollutions of big// cities may harm their unborn child by the air they inhale. Inhalation of polluted air of the metros can change the chromosomes of the fetus in womb. Pollutant particles emitted from the cars, trucks, buses, tobacco smoke, combustion etc can penetrate the placenta enough to harm the chromosome of the fetus....Hunt for Chromosomal Errors Which Cause Genetic Diseases
