Identifying the source of stem cells
When most animals begin life, cells immediately begin accepting assignments to become a head, tail or a vital organ. However, mammals, including humans, are special. The cells of mammalian embryos get to make a different first choice -- to become the protective placenta or to commit to forming the baby.

Study examines availability of tanning beds on and near college campuses
Among the top 125 colleges on a list compiled by US News & World Report, 48 percent have indoor tanning facilities either on campus or in off-campus housing despite evidence that tanning is a risk factor for skin cancer, according to a study published online by JAMA Dermatology.

Study sheds light on genetic architecture of kidney cancer
A new study on a large cohort of kidney cancer patients in Europe sheds light on the genetic architecture of the disease -- and reveals an apparent link between exposure to aristolochic acid and incidence of kidney cancer, particularly in Romania.

Kidney cancer in Central Europe
Large-scale DNA and RNA sequencing of renal cell carcinoma patients in Europe reveals primary causes of kidney cancer vary between populations. Findings provide insights into the genetic architecture of clear-cell renal-cell carcinoma. Association between cancer incidence and exposure to aristolochic acid -- an ingredient in some herbal remedies -- has implications for public health, particularly in Romania.

New molecular imaging technology could improve bladder-cancer detection
Researchers at the Stanford University School of Medicine have developed a new strategy that they say could detect bladder cancer with more accuracy and sensitivity than standard endoscopy methods. Endoscopy refers to a procedure in which surgeons use an instrument equipped with a lens to see inside the patient.

A new study has found that certain prostate cancer medications are linked with an increased risk of dying from heart-related causes in men with congestive heart failure or prior heart attacks. Published in BJU International, the findings will help doctors and patients weigh the benefits and risks of the drugs.

Scientists generate first human stomach tissue in lab with stem cells
Scientists used pluripotent stem cells to generate functional, three-dimensional human stomach tissue in a laboratory -- creating an unprecedented tool for researching the development and diseases of an organ central to several public health crises, ranging from cancer to diabetes. Scientists at Cincinnati Children's Hospital Medical Center report Oct. 29 in Nature they used human pluripotent stem cells -- which can become any cell type in the body -- to grow a miniature version of the stomach.

'Treasure in saliva' may reveal deadly diseases early enough to treat them
UCLA research could lead to a simple saliva test capable of diagnosing -- at an early stage -- diabetes and cancer, and perhaps neurological disorders and autoimmune diseases. The study, the most comprehensive analysis ever conducted of RNA molecules in human saliva, reveals that saliva contains many of the same disease-revealing molecules that are contained in blood.

New research presented at the Society for Integrative Oncology Conference in Houston, showed for the first time that it's possible to eliminate HPV infection in women using AHCC, a readily available nutritional supplement. Results, presented by Dr. Judith A. Smith, Pharm.D., associate professor, University of Texas Health Science Center at Houston Medical School, was selected for special research platform presentation as 'Best of SIO.' HPV is associated with 99 percent of cervical cancers.

First detailed picture of a cancer-related cell enzyme in action on a chromosome unit
New insight into the function of an enzyme related to the BRCA1 breast-cancer protein is published in this week's issue of Nature. The study produced the first detailed working image of an enzyme in a group that is associated with many types of cancer. The researchers obtained the first crystal structure of a gene-regulation enzyme working on a nucleosome. The image reveals previously unknown information about how the enzyme attaches to its nucleosome target.

New technology on the way to aid cancer suffers who lose their hair after chemotherapy
Cancer suffers who lose their hair as a consequence of chemotherapy will benefit from a major research project that will improve the scalp cooling technology that prevents hair loss. The research is being now underway and is being pioneered by global scalp cooling manufacturing company, Paxman Coolers, of Fenay Bridge, Huddersfield, in conjunction with the biology department of the University of Huddersfield.

Tea and citrus products could lower ovarian cancer risk, new UEA research finds
Tea and citrus fruits and juices are associated with a lower risk of developing ovarian cancer, according to new research from the University of East Anglia. The team found that those who consumed food and drinks high in flavonols -- found in tea, red wine, apples and grapes -- and flavanones -- found in citrus fruit and juices -- were less likely to develop the disease.

New findings show that different brain tumors have the same origin
Glioma is a common name for serious brain tumors. Different types of glioma are usually diagnosed as separate diseases and have been considered to arise from different cell types in the brain. Now researchers at Uppsala University have shown that one and the same cell of origin can give rise to different types of glioma. This is important for the basic understanding of how these tumors are formed and can contribute to the development of more efficient and specific glioma therapies.
