Health care politics: Perry's stem cell controversy, presidential contenders and health law; Biden Medicare fact check

Texas Gov. Rick Perry, who recently underwent an experimental injection of his own adult stem cells to relieve back pain, pushed a bill through the Legislature in June that paves the way for a company co-owned by his doctor to become the first state-approved "bank" to store and cultivate such cells for medical treatment that fact illustrates two aspects of his record that are drawing increasing attention as he pursues the presidency: his enthusiasm for ideas that are sometimes outside the scientific mainstream and what critics view as his willingness to use the levers of state government to benefit friends and political benefactors.

Jefferson's two-step bone marrow transplant procedure holds promise for cancer patients

Half-matched bone marrow or stem cell transplants for blood cancer patients have typically been associated with disappointing clinical outcomes. However, a clinical trial conducted at the Kimmel Cancer Center at Jefferson testing its unique, two-step half-match procedure has produced some promising results: the probability of overall survival was 45 percent in all patients after three years and 75 percent in patients who were in remission at the time of the transplant.

Alcohol reduces awareness of how much a person cares about making mistakes

Most people have witnessed otherwise intelligent people doing embarrassing or stupid things when they are intoxicated, but what specifically happens in the brain to cause such drunken actions? A new study testing alcohol's effects on brain activity from the University of Missouri says that alcohol dulls the brain "signal" that warns people when they are making a mistake, ultimately reducing self control.

New medicines to target LPA receptors may prevent serious developmental brain diseases

Examining brain damage that occurs when fetuses in the womb are deprived of oxygen, researchers at The Scripps Research Institute have discovered that damage does not occur randomly but is linked to the specific action of a naturally occurring fatty molecule called LPA, acting through a receptor that transfers information into young brain cells.

Researchers modify toxic chemical of marine cycyanobacteria to treat colon cancer

University of Florida researchers have modified a toxic chemical produced by tiny marine microbes and successfully deployed it against laboratory models of colon cancer.

Discovery in rare disease may shed light on common causes of blindness

In a rare eye disease, the retina degenerates because light-receiving cells fail to regenerate, research led by a student at Case Western Reserve University School of Medicine shows.

Microtubule stability linked to increased sensitivity to paclitaxel

SCIENTISTS have discovered how blocking key cell signalling proteins could help boost the success rate of the tumour-shrinking drug paclitaxel, according to a study published in the journal Cancer Research today.

Contraceptive pill prevents loss of eye sight

Scientists at University College Cork (UCC) have shown that the active component (Norgestrel) of the contraceptive 'Mini Pill' prevents the loss of sight in mice that have degenerative eye conditions that normally lead to blindness.

Blocked blood vessels linked to familiar signs of aging

Many common signs of aging, such as shaking hands, stooped posture and walking slower, may be due to tiny blocked vessels in the brain that can't be detected by current technology.

Chromatin might have another life as direct signaling molecule

Chromatin - the intertwined histone proteins and DNA that make up chromosomes - constantly receives messages that pour in from a cell's intricate signaling networks: Turn that gene on. Stifle that one. But chromatin also talks back, scientists at The University of Texas MD Anderson Cancer Center report today in the journal Cell, issuing orders affecting a protein that has nothing to do with chromatin's central role in gene transcription - the first step in protein formation.

New genetic screening program for families at high risk of colorectal cancer

UT Southwestern Medical Center has developed a new lifesaving genetic screening program for families at high risk of contracting colorectal cancer, a deadly yet highly preventable form of cancer.

Pemetrexed treatment produces better outcomes in ALK-translocated NSCLC patients

Patients with ALK-rearranged non-small cell lung cancer (NSCLC) responded significantly better to pemetrexed than patients whose cancer did not show ALK translocation, according to research published in the September issue of the Journal of Thoracic Oncology, the official publication of the International Association for the Study of Lung Cancer.

UVA researchers develop 3-D model to visualize early growth of human breast tissue

University of Virginia researchers have developed a revolutionary three-dimensional model that allows them to visualize how breast tissue grows in its earliest stages, giving them the closest look ever at the very beginnings of breast cancer.

Neutrophils linked to growth and spread of cancer

Scripps Research Professor James Quigley, Staff Scientist Elena Deryugina, and colleagues had previously demonstrated that white blood cells known as neutrophils—bone marrow-derived cells that function as "first responders" at sites of acute inflammation—promote the growth of new blood vessels in normal, healthy tissue.

UTHealth Phase I trial: Bone marrow stem cell therapy feasible, safe for acute stroke patients

Using a patient's own bone marrow stem cells to treat acute stroke is feasible and safe, according to the results of a ground-breaking Phase I trial at The University of Texas Health Science Center at Houston.

Ancient antibiotic resistance findings leads experts to stress need to use antibiotics sparingly

"An analysis of 30,000-year-old bacteria whose DNA has been recovered from the Yukon permafrost shows that they were able to resist antibiotics," providing "the first direct evidence that antibiotic resistance is a widespread natural phenomenon that preceded the modern medical use of antibiotics," according to a study in Thursday's issue of the journal Nature, the New York Times reports.

One third of patients with unexplained body malodor production test positive for TMAU

Scientists from the Monell Center report that approximately one third of patients with unexplained body malodor production test positive for the metabolic disorder trimethylaminuria.

Princeton researchers match images of brain activity with complex thought

In an effort to understand what happens in the brain when a person reads or considers such abstract ideas as love or justice, Princeton researchers have for the first time matched images of brain activity with categories of words related to the concepts a person is thinking about. The results could lead to a better understanding of how people consider meaning and context when reading or thinking.
