CLEARWATER, FL--(Marketwire -03/19/12)- Biostem U.S., Corporation (OTCQB: BOSM.PK - News) (Pinksheets: BOSM.PK - News) (Biostem, the Company), a fully reporting public company in the stem cell regenerative medicine sciences sector, announced today the addition of Perinatologist Sanford M. Lederman, MD to its Scientific and Medical Board of Advisors (SAMBA). As Chairman of the Department of Obstetrics and Gynecology at New York Methodist Hospital in Brooklyn, Dr. Lederman is consistently recognized by New Yorker Magazine's list of "Top Doctors" in New York. A specialist in high-risk pregnancy issues, Dr. Lederman has authored a number of scientific papers and is a highly regarded public speaker. He adds a very important dimension to the Biostem Scientific and Medical Board of Advisors by bringing specialized knowledge regarding the potential use of stem cell applications for the health of women and children. Biostem President Dwight Brunoehler said, "Dr. Lederman is one of the most highly respected Obstetric and Gynecological physicians in the country. Sandy and I have worked together very actively on stem cell projects for over 18 years, including setting up a cord blood stem cell national donation system where all expectant moms have a chance to donate their baby's cord blood to benefit … Continue reading →

ScienceDaily (Mar. 16, 2012) Researchers at the University of Pittsburgh School of Medicine have identified a cell-signaling pathway that plays a key role in increasing insulin secretion during pregnancy and, when blocked, leads to the development of gestational diabetes. Their findings are available online March 16 in Diabetes, one of the journals of the American Diabetes Association. During pregnancy, pancreatic beta cells should expand and produce more insulin to adapt to the needs of the growing baby, explained senior investigator Adolfo Garcia-Ocana, Ph.D., associate professor of medicine, Division of Endocrinology and Metabolism, Pitt School of Medicine. Newborns can suffer complications if the mother's blood glucose is abnormally high during pregnancy, a condition known as gestational diabetes. "Not much was known about the maternal mechanisms that lead to increased beta cell number and function during pregnancy," Dr. Garcia-Ocana said. "But research has shown that high blood glucose in pregnancy can have long-term health consequences for the child, as well as a greater risk of hypertension, type 2 diabetes, and high cholesterol for the mother." His team began studying a protein called hepatocyte growth factor (HGF), which was discovered by George K. Michalopoulos, M.D., Ph.D., professor and chair, Department of Pathology, Pitt … Continue reading →

LOS ANGELES, Calif. - The creation of California's stem cell agency in 2004 was greeted by scientists and patients as a turning point in a field mired in debates about the destruction of embryos and hampered by federal research restrictions. The taxpayer-funded institute wielded the extraordinary power to dole out $3 billion in bond proceeds to fund embryonic stem cell work with an eye toward treatments for a host of crippling diseases. Midway through its mission, with several high-tech labs constructed, but little to show on the medicine front beyond basic research, the California Institute for Regenerative Medicine faces an uncertain future. Is it still relevant nearly eight years later? And will it still exist when the money dries up? The answers could depend once again on voters and whether they're willing to extend the life of the agency. Several camps that support stem cell research think taxpayers should not pay another cent given the state's budget woes. "It would be so wrong to ask Californians to pony up more money," said Marcy Darnovsky of the Center for Genetics and Society, a pro-stem cell research group that opposed Proposition 71, the state ballot initiative that formed CIRM. Last December, CIRM's … Continue reading →

Washington, March 16 (IANS) Radiation from cell phone use during pregnancy could affect the brain of foetus, potentially leading to hyperactivity after birth. "This is the first experimental evidence that foetal exposure to radio frequency radiation from cellular telephones does in fact affect adult behaviou," said study co-author Hugh S. Taylor, professor of reproductive endocrinology and Infertility at Yale School of Medicine. Taylor and co-authors exposed pregnant mice to radiation from a muted and silenced cell phone positioned above the cage and placed on an active phone call for the duration of the trial, according the journal Scientific Reports. The team measured the brain electrical activity of adult mice that were exposed to radiation as foetuses, and conducted a battery of psychological and behavioral tests, according to a Yale statement. They found that the mice exposed to radiation tended to be more hyperactive and had reduced memory capacity. Taylor attributed the behavioural changes to an effect during pregnancy on the development of neurons in the prefrontal cortex region of the brain. Attention deficit hyperactivity disorder (ADHD), is a developmental disorder, characterized by inattention and hyperactivity. "We have shown that behavioral problems in mice that resemble ADHD are caused by cell … Continue reading →

March 16, 2012 Yale School of Medicine researchers have concluded that exposure to cell phones during pregnancy affects the brain development of the offspring and may cause hyperactivity. The researchers are drawing their conclusions based on studies conducted on mice. This is the first experimental evidence that fetal exposure to radio frequency radiation from cellular telephones does in fact affect adult behavior, said senior author Hugh S. Taylor, M.D., professor and chief of the Division of Reproductive Endocrinology and Infertility in the Department of Obstetrics, Gynecology & Reproductive Sciences. To conduct the study, the researchers exposed two groups of pregnant mice to different levels of radiation. The first group of pregnant mice was exposed to radiation from a muted and silenced cell phone placed on top of their cages. A call was placed and left active for the duration of the test, which lasted 17 days. The second group of mice acted as a control and were left in the same conditions but with the cell phone deactivated. According to the study, the mice were exposed to 800-1900 MHz frequency radiation. What is less clear, however, is whether or not the mice were exposed to the entire spectrum between 800 … Continue reading →
