Fertility centers are able to screen for a growing number of genetically related conditions, but what should doctors do if no embryos without the targeted condition are available for transfer and the parents request that affected embryos should be transferred instead This question was posed to the 24th annual meeting of the European Society of Human...http://www.eurekalert.org/pub_releases/2008-07/esfh-sew070608.php Some antidepressants associated with gastrointestinal bleeding- July 7, 2008 A class of antidepressants known as selective serotonin reuptake inhibitors appear to be associated with bleeding in the upper gastrointestinal tract, according to a report in the July issue of Archives of General Psychiatry, one of the JAMAArchives journals. The effects appear increased when antidepressants are combined with other stomach-harming medications and decreased when acid-suppressing agents are used.http://www.eurekalert.org/pub_releases/2008-07/jaaj-saa070308.php New ovarian stimulation technique offers more cancer patients the chance to preserve their fertility- July 7, 2008 Researchers have shown for the first time that it is possible to stimulate a woman's ovaries to produce eggs for collection during the final phase of the menstrual cycle. The finding offers the chance for more women who have been diagnosed with cancer to restore their fertility following chemotherapy or radiotherapy -- cancer treatments that can seriously damage the ovaries, often permanently. The findings were presented at the 24th annual meeting of the European Society of Human Reproduction...http://www.eurekalert.org/pub_releases/2008-07/esfh-nos070608.php European league-tables for antibiotic resistance revealed- July 7, 2008 Tests of antibiotic resistance in cattle have revealed stark variation across thirteen European countries. The results, published today in BioMed Central's open-access journal Acta Veterinaria Scandinavica, show that major differences were apparent in the occurrence of resistance between countries and between the different antimicrobial agents tested.http://www.eurekalert.org/pub_releases/2008-07/bc-elf070308.php CO2 increase in the atmosphere augments tolerance of barley to salinity- July 7, 2008 In future, climate change will bring an increase in salty surfaces on the Earth and in the concentration of CO2 in the atmosphere. However, this higher CO2 has some positive effects on the physiology of barley plants and increases its tolerance to salinity. This is the conclusion of the Ph.D. thesis of Ms. Usue Prez-Lpez, defended at the University of the Basque Country.http://www.eurekalert.org/pub_releases/2008-07/ef-cii070708.php Lay your eggs here- July 7, 2008 North Carolina State University scientists have figured out one reason why pregnant yellow fever mosquitoes (Aedes aegypti), one of the most important disease transmitters worldwide, choose to lay their eggs in certain outdoor water containers while eschewing others.http://www.eurekalert.org/pub_releases/2008-07/ncsu-lye070308.php Protein thought to promote cancer instead functions as a tumor suppressor- July 7, 2008 A protein previously thought to promote colorectal cancer instead suppresses the growth of human cancer cells in culture, researchers at UT Southwestern Medical Center have found.http://www.eurekalert.org/pub_releases/2008-07/usmc-ptt070308.php Disruption of blood sugar levels after heart surgery is common- July 7, 2008 A study reveals today that inadequate blood sugar control in patients having heart surgery is associated with a four fold increase in post-surgery death and major complications -- and that the blood sugar disturbances occur in patients with and without diabetes.http://www.eurekalert.org/pub_releases/2008-07/uob-dob070708.php Stanford researchers find molecule that kills kidney cancer cells- July 7, 2008 Kidney cancer patients generally have one option for beating their disease: surgery to remove the organ. But that could change, thanks to a new molecule found by Stanford University School of Medicine researchers that kills kidney cancer cells.http://www.eurekalert.org/pub_releases/2008-07/sumc-srf070208.php Can recycling be used to treat cancer- July 7, 2008 We already know that recycling benefits our planet; and now new research suggests that the cellular version might be useful for battling cancer. Scientists at Stanford University have identified a molecule that uses this unexpected pathway to selectively kill cancer cells. The research, published by Cell Press in the July 8 issue of the journal Cancer Cell, may drive treatment strategies for cancer in an entirely new direction.http://www.eurekalert.org/pub_releases/2008-07/cp-crb062708.php |
