Preimplanted Genetic Screening Should Be Interpreted With Caution
..., we could elucidate the origin of the chromosomal aberrations
and follow different chromosomal modifications as they occurred during preimplantation period. The timing is significant because embryos used in IVF are normally transferred at between 3 and 5 days old, says Ms Frumkin. We found that embryos which ...
Soft Contacts Designed for Cone-Shaped Cornea
... surface profiles designed to correct for specific aberrations
of the cornea and crystalline lens. The scientists designed the front profiles by measuring with wavefront sensors exactly how light enters the subjects' eyes through the misshapen cornea. In collaboration with Bausch & Lomb, an oscillating tool lath...
The Story Behind the Shape of the Heart
...tures. Disruption of this balance may underlie the aberrations
observed in some types of heart disease. Source-Eurekalert...
Novel Test Identifies Leukemia Patients Likely to Respond to New Therapy
... immune-system cells that make antibodies. Genetic aberrations
can cause B cells to multiply uncontrollably, causing B cell lymphomas. Dr. Melnick’s study focused on a gene called BCL6. The protein it codes for is a transcriptional repressor, which means that it can shut off the functioning of genes in B cells...
Mutation In PALB2 Elevates Risk of Cancer
...first involved comprehensive screening for genetic aberrations
in 113 Finnish breast cancer families. The same constitutional mutation in PALB2 was observed in three families. It was later showed that the relevant mutant protein is deficient in its ability to support the kinds of DNA damage responses in which PA...
Simple Test Detects Genetic Signs of Lung Cancer in a Patient’s Sputu
...ngs, of course, but we have shown that the genetic aberrations
seen in sputum reflect the same genetic aberrations
found in lung tumors, and that these molecular changes occur before any morphological changes can be...
Culprit Gene Behind Childhood Kidney Cancer Discovered
...samples taken from 82 patients to evaluate genetic aberrations
that are connected to the disease. During the process, the mutation in WTX gene was identified, though the knowledge about the key purpose of the protein encoded by WTX still remains a mystery. Yet the position of the gene on the X chromosome has r...
Cardiac Patients Take Heart - PUFA is Here to Help You!
... PUFA helps to reduce the intensity of some of the aberrations
that are seen in cardiac function which usually reflects a bad prognosis, in those who have recently suffered from a Congestive Cardiac Failure (CCF) but have there after stabilized. Twenty five patients who had certain amount of damage done to the...
Hunt for Chromosomal Errors Which Cause Genetic Diseases
...r in one in 1,000 live births. Frequently the gene aberrations
harm multiple organ systems. For example, patients with chromosome 22q11.2 deletion syndrome may have heart defects, impaired immunity and developmental delay. Deletions of several genes in Prader-Willi syndrome may cause obesity and mental retardati...
Occupational Exposure To Radiation Causes Chromosome Aberrations
...tonium exposure and risk of developing Chromosomal aberrations

and disease condition which would be helpful in establishing diagnosis and better treatment. The res...
Study links Ritalin to Cancer
...w increase in chromosomal aberrations. Chromosomal aberrations
are often linked with increased cancer risk. The researchers are of the opinion that these findings need to be further investigated before use of Ritalin can be conclusively related to cancer. However, although the situation is not drastic, but s...
