Chemists create 'Superbowl' molecule; May lead to better health
In a development that could one day score a touchdown for better health, chemists in Australia have created a "superbowl" molecule that shows promise for precision drug delivery, according to a recent study in the Journal of the American Chemical Society. Shaped like a miniature football stadium, the molecule is capable of delivering a wide range of drugs ?from painkillers to chemotherapy cocktai...Poor prenatal nutrition permanently damages function of insulin-producing cells in the pancreas
Scientists at Joslin Diabetes Center have discovered one reason why infants with low birth weight have a high potential of developing type 2 diabetes later in life. In studies of mice, the researchers found that poor prenatal nutrition impairs the pancreas's ability to later secrete enough insulin in response to blood glucose. "The bottom line is that if you don't have delivery of enough...Bound for destruction: Ubiquitination protects against improper Notch signaling
The is an important molecular signaling mechanism whose existence has beenknown, or at least hinted at, for nearly a century since theidentification of a mutant strain of Drosophila fruit flies with“notched?wings in Thomas Hunt Morgan’s lab in 1910. Later studiesrevealed that the Notch gene encodes a receptor protein tha...Sea skate experiment sheds light on human cell transport
Along with Mark Musch, a longtime University of Chicago collaborator, Goldstein conducted an experiment with the red blood cells of skates to understand how these skinny, graceful fish can swim from salt water to fresh water. For humans, such a drastic environmental change would prompt an equally drastic physiological change: Our cells would take in too much water, diluting blood and other body f...Experiments provide proof of how traveling in groups protects insects
Few events involving animals are more dramatic than when they band together and head out on the march cross-country. Among examples are the many thousands of wildebeests and other hoofed mammals that form herds and migrate across the African plains. and young locusts also sometimes unite with their...HybArray 12 DNA hybridization system from PerkinElmer

A minimally invasive direct coronary artery bypass (MIDCAB) procedure was performed at Pittsburgh while the patient was awake. The operation was done under thoracic epidural anesthesia. This approach may help in discharging the patient early from the hospital. Dr. Zenati from the team of doctors who performed the surgery said that patients who are operated in this way may not have to go t...PRIMARY PULMONARY HYPERTENSION GENE DISCOVERED
The discovery of the gene associated with the inherited form of primary pulmonary hypertension (PPH) by Drs. Jane H. Morse of Columbia University and James A. Knowles of the Columbia Genome Center is indeed a major breakthrough. Their study, funded in part by the National Heart, Lung, and Blood Institute at the National Institutes of Health and published in the September issue of th...Homeopathic preparation better than placebo in perennial allergic
A homeopathic preparation for perennial allergic rhinitis appears to be more effective than placebo. A multicenter team studied 50 patients with perennial allergic rhinitis. The subjects were randomized to receive either 30cc of a homeopathic preparation of principal inhalent allergen or placebo. In the third and fourth week after the start of treatment, the group compared changes in nasa...Sperm washing helps couples – Breakthrough in focu
In many unfortunate instances we see couples who are HIV sero discordant but who would like to have a baby. If the husband is HIV –1 positive and the wife is negative and they are planning to have a child the problem arises because sexual intercourse carries a 1 in 500 risk of transmitting the virus to the female partner and through her to the fetus. Sperm washing is a risk-reduction opti...Patient’s perception of health status helps in better recover
We always insist that we should feel healthy to actually live healthy. Doctors in England say that following a coronary bypass surgery; the patient’s attitude helps in an early recovery. To justify this argument the researchers conducted a health survey just before coronary bypass operations and assessed the patient’s own perception of his/her own health status. Following surgery those wh...Nagahara Nucleus Chopper - Left
