Women often opt to surgically remove their breasts, ovaries to reduce cancer risk

... counselors and women at risk for breast cancer. Questions to be raised should include how is the communication method occurring, are the doctors sympathetic and is there an ongoing dialogue? "Careful risk counseling does appear to influence women's decision for surgery although the effect is not ...

Researcher garners major award from NIH for further exploration into the mechanisms of obesity

... in the nerves of Siberian hamsters, they found that the brain uses part of the nervous system used to regulate body functions, called the sympathetic nervous system, to initiate fat burning and then sensory nerves, in turn, communicate back to the brain cells to continue or stop the fat burning ...

Medicare coding for maggots and maggot therapy

... difficulties getting reimbursed by insurance companies and Medicare subcontractors for their maggot therapy expenses. Medicare officials were quite sympathetic to the requests for better coding and processing of insurance claims for maggot therapy, explaining that product coding and reimbursement needed to ...

A double-barreled immune cell approach for neuroblastoma

... virus lasted as long as 18 months and at higher levels than the other cells. Neuroblastoma is a tumor of primitive cells that go on to form the sympathetic nervous system. Apart from brain tumors, it is the most common solid cancer of children, and accounts for 7 percent of the total. In two-thirds of ...

Tumor-targeting viral therapy slows neuroblastoma, malignant peripheral nerve sheath tumors

... in the restriction of new blood vessel growth that can feed tumors, Dr. Cripe said. Neuroblastoma is a solid tumor cancer that begins in the sympathetic nervous system and most often strikes children younger than 5 years old. For children younger than 2, or those with a single mass tumor, the ...

Nicotine may accelerate atherosclerosis, may be as dangerous as tar

... Surgery at Weill Cornell Medical College. Previous studies have suggested that nicotine in cigarettes can hurt the heart by activating the sympathetic nervous system and increasing the heart rate -- potentially leading to fatal arrhythmias. (Nicotine also affects most organ systems -- including the ...

How appetite-stimulating brain cells work overtime during fasting

... brown fat is the activation of mitochondrial uncoupling protein 1 (UCP1) by T3, the researchers said. The UCP1 activation, which is controlled by the sympathetic nervous system, also leads to an increase in the number of mitochondria. The role of the related protein, UCP2, which is present at high levels ...

Botox could help target resistant tumors for treatment

... acetylcholine and norepinephrine. Gallez and his colleagues hypothesized that since Botulinum toxin impeded neurotransmitter release in the sympathetic nervous system, it could prevent neuromuscular contractions of vessels in tumors. The inhibition of this contraction could literally open the gate to ...

Survival of heart patients on beta-blockers varies greatly with genetic variation

... of efficacy of beta-blockers in higher-risk patients or if genotype alone is responsible for a worse outcome." Beta-adrenergic receptors in the sympathetic nervous system respond to adrenaline, but beta-blocker drugs block this interaction, slowing the heartbeat and lowering blood pressure to relieve ...
