LOS ANGELES (Oct. 8, 2009) -- Premature aging of the immune system appears to play a role in the development of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, according to research scientists from the Maxine Dunitz Neurosurgical Institute at Cedars-Sinai Medical Center, the Weizmann Institute of Science in Israel, and Sheba Medical Center in Israel.
Individuals with ethanol in their bloodstreams appear less likely to die following a moderate to severe head injury, according to a report in the September issue of Archives of Surgery, one of the JAMA/Archives journals.
CORVALLIS, Ore. -- A new study has concluded that one key part of the immune system, the ability of vitamin D to regulate anti-bactericidal proteins, is so important that is has been conserved through almost 60 million years of evolution and is shared only by primates, including humans -- but no other known animal species.
LOS ANGELES (July 22, 2009) -- Cancer stem-like cells have been implicated in the genesis of a variety of malignant cancers. Research scientists at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute have isolated stem-like cells in benign (pituitary) tumors and used these "mother" cells to generate new tumors in laboratory mice.
June 26, 2009 - (BRONX, NY) - A variation in a gene that is active in the central nervous system is associated with increased risk for obesity, according to an international study in which Albert Einstein College of Medicine of Yeshiva University played a major role. The research adds to evidence that genes influence appetite and that the brain plays a key role in obesity.
TORONTO -- Combining high-definition positron emission tomography (PET) and "motion-frozen" technology provides enhanced cardiac images. The motion-frozen technology adds physiological details that were previously invisible to physicians, according to researchers at SNM's 56th Annual Meeting in Toronto.
CHICAGO, IL (June 2, 2009) -- Researchers will present the latest advances in a technology that continues to change the face of gastroenterology and surgery, known as Natural Orifice Translumenal Endoscopic Surgery®, or NOTES®, today at Digestive Disease Week® 2009 (DDW®).
Despite aggressive treatment, glioblastoma multiforme (GBM) ? the most common and deadly of brain cancers ? usually claims the lives of its victims within six to 12 months of diagnosis. This statistic has changed little over the years, largely because the cancer grows so quickly that neither surgery, radiation, or chemotherapy can stop it. Now, researchers at Cedars-Sinai Medical Center have found that a small protein called hsFlt3L delivered via a genetically engineered virus increased the number of immune cells in the brain and significantly slowed tumor growth, increasing the survival of laboratory rats in pre-clinical studies. The study, published in the December issue of the journal, Molecular Therapy, may lead to a new way to treat patients with GBM.
When molecules in cells are stimulated by light, they respond by becoming excited and re-emitting light of varying colors (fluorescence) that can be captured and measured by highly sensitive optical equipment. Now, researchers at Cedars-Sinai Medical Center and the University of Southern California are developing miniaturized spectroscopic instruments and computer software to take a real-time look at biochemical, functional and structural changes occurring within the cells and tissue of the brain. If the technology continues to progress as anticipated, neurosurgeons will be able to shine a light during surgery to diagnose brain tumors instantaneously and they will be able to discern the borders of tumors with greater precision than ever. Early studies appear to support these possibilities.
Baby fat may be cuddly to new parents but pediatricians are increasingly warning families about serious medical problems resulting from baby fat that never goes away. Type 2 diabetes is on the increase in overweight and obese children in America. According to Cedars-Sinai Medical Center pediatric endocrinologist David Geller, M.D., Ph.D. "Childhood obesity is the primary reason we are seeing such a huge increase in type 2 diabetes in kids today. Clearly there is an inexorable increase in body girth and body mass in our children which needs to be taken seriously in order to avoid a lifetime of physical and psychological problems."
Scientists at Cedars-Sinai Medical Center will work closely with clinicians to develop a new generation of minimally invasive tools and techniques at the hospital's newly created Minimally Invasive Surgical Technology Institute. The Institute was established through a $1 million grant awarded by the Office of Naval Research in November 2002 and internal contributions from Cedars-Sinai. Under the direction of biophysicist and Fulbright scholar Daniel L. Farkas, Ph.D., the Institute brings together a scientific research group, a pre-clinical facility and a clinical assessment team, all focusing collaboratively on the development, testing and introduction of noninvasive technologies into everyday surgical practice.
According to an article in the February 5 issue of the Journal of the American College of Cardiology, coronary artery disease in young women appears to be related to estrogen deficiency, and there may be a link to psychosocial stress. The findings are based on an analysis of statistics compiled from a major ongoing investigation of heart disease in women that is led by cardiac researchers in Los Angeles. "Although coronary artery disease is the leading killer of premenopausal women, taking even more lives than breast cancer does, most studies have focused on heart disease in older women. Our findings demonstrate for the first time that young women with low blood estrogen levels have a significantly greater prevalence of coronary artery disease," said C. Noel Bairey Merz, M.D., the article's first author.
When 29-year-old Eric Lange suddenly experienced several hours of mental confusion last July, physicians at Cedars-Sinai Medical Center naturally ordered brain scans and carotid artery studies in their first search for a cause. With the initial exams turning out OK, Eric's neurologist pursued other clues and ended up finding a heart defect called a patent foramen ovale, or PFO. A blood clot was believed to have slipped through the defect and out of the normal route of circulation that would have filtered it in the lungs. Instead, the clot traveled to Eric's brain and temporarily blocked the flow of blood, causing a transient ischemic attack, or TIA, which is similar to a stroke but it does not cause permanent brain damage.
Using a common diabetes drug, researchers in Los Angeles have successfully treated pituitary tumors that cause a potentially life-threatening condition known as Cushing's syndrome. The most common type of Cushing's syndrome is caused by prolonged high-level exposure of a hormone called ACTH (adrenocorticotropin), which is secreted in excess by tumors of the pituitary gland, situated at the base of the brain and, which controls growth, metabolism and reproduction. Although the disorder is rare, it affects more women than men by a ratio of 5:1. Symptoms include weight gain with rounding of the face; increased fat in the neck; thinning skin; excess hair growth on the face neck, chest abdomen and thighs; muscle weakness and bone loss (osteoporosis); high blood sugar; diabetes; and high blood pressure.
A disorder in which the body fails to make a particular enzyme --- leading to severe pain in the hands and feet, and eventual damage to internal organs --- has been successfully treated for the first time in Los Angeles.
