BEIJING, Nov. 9 /PRNewswire-Asia-FirstCall/ -- China Medical Technologies, Inc. (the "Company") (Nasdaq: CMED), a leading China-based medical device company that develops, manufactures and markets advanced in-vitro diagnostic products, today announced that the Company has received approval for its Leukemia BCR/ABL fusion gene detection FISH Probe (the "Leukemia BCR/ABL FISH Probe") from the State Food and Drug Administration of China (the "SFDA"). The Leukemia BCR/ABL FISH Probe is a...

Cornell researchers have discovered a genetic mechanism in fruit flies that prevents two closely related species from reproducing, a finding that offers clues to how species evolve. When two populations of a species become geographically isolated from each other, their genes diverge from one another over time. Eventually, when a male from one group mates with a female from the other group, the offspring will die or be born sterile, as crosses between horses and donkeys produce sterile mules....

Men that suffer from a rare disease where they are plagued with extra female genes can still produce children after having surgery that gathers their sperm, says a new study. Men with Klinefelter's syndrome have an extra X chromosome. Usually men have a single X and Y-chromosome, and women have two X chromosomes. Men with Klinefelter's syndrome have two X and one Y chromosome, which can affect their fertility. Dr. Ranjith Ramasamy at New York-Presbyterian Hospital employed a surgery that...

A Florida State University scientist says he's found the cause of chromosomal birth defects, such as Down, XYY, Edwards, Patau and Turner's syndromes. Using yeast genetics, Assistant Professor Hong-Guo Yu and colleagues selectively removed a single protein from the cell division process called meiosis and found that when the protein known as Pds5 is missing, chromosomes fail to segregate and pair up properly, and birth defects can result. Researchers said the study shines new light on the...

Using yeast genetics and a novel scheme to selectively remove a single protein from the cell division process called meiosis, a cell biologist at The Florida State University found that when a key molecular player known as Pds5 goes missing, chromosomes fail to segregate and pair up properly, and birth defects such as Down syndrome can result. That discovery is groundbreaking, but so, too, is what principal investigator Hong-Guo Yu calls the "genetics trick" performed by his research team...

New insights gained into how polyploidy and genomic change can lead to evolutionary change and plants' fitness and vigor An individual with Down syndrome and a male calico cat have one thing in common"”each has an extra chromosome. For animals, most instances of an extra chromosome result in birth defects or even death, but plants are another matter entirely. Many plants are able to survive the presence of an extra copy of their entire genome (known as polyploidy) and are often even...

New study proves that communication between male and female occurs in our innermost beings In the week that the University of Leicester celebrates the 25th anniversary of the discovery of DNA fingerprinting (Thursday September 10) new findings from the world-renowned University of Leicester Department of Genetics reveal for the first time that the male and female do truly communicate "“at least at the fundamental genetic level. The research counters scientific theory that the X and Y...

The unique mechanism behind the evolutionary survival of the human Y chromosome may also be responsible for a range of sex disorders, from failed sperm production to sex reversal to Turner Syndrome. Roughly six years ago, David Page's lab at Whitehead Institute for Biomedical Research reported the discovery of eight large areas of mirror-imaged genetic sequences, or palindromes, along the Y chromosome. Because the Y chromosome essentially has no partner with which to swap genes, a process...

Parents of healthy newborns often remark on the miracle of life. The joining of egg and sperm to create such delightful creatures can seem dazzlingly beautiful if the chromosome information from each parent has been translated properly into the embryo and newborn.The darker side is that when extra copies of chromosomes or fewer than the normal 46 (23 from each parent) are present, tragic birth defects can occur. Now, scientists at the University of Georgia have developed a model system for...
