Scientists move closer to growing therapeutic brain cells in laboratory

Bethesda, MD-A group of really brainy scientists have moved closer to growing "therapeutic" brain cells in the laboratory that can be re-integrated back into patients' brains to treat a wide range of neurological conditions.

Liquid biopsy: New device could help doctors diagnose and treat cancers

A microfluidic chip developed at the University of Michigan is among the best at capturing elusive circulating tumor cells from blood-and it can support the cells' growth for further analysis.

Discoveries pave way for use of new therapies for advanced thyroid cancer

For many years, patients with advanced thyroid cancer faced bleak prospects and no viable treatment options. But now, building on recent discoveries about the genetics and cell signaling pathways of thyroid tumors, researchers are developing exciting new weapons against the disease, using kinase inhibitors that target tumor cell division and blood vessels.

Human breast tumors transplant could be valuable tools in search for better treatments

Breast cancer that spreads to other organs is extremely difficult to treat. Doctors can buy patients time, but a cure remains elusive. Now, researchers at Washington University School of Medicine in St. Louis have shown that human breast tumors transplanted into mice are excellent models of metastatic cancer and could be valuable tools in the search for better treatments.

Study: 4% of head-trauma scans in children have unexpected results that may need follow up

The largest study of computed tomographic scans taken in emergency departments across the country for children with head injuries describes the prevalence of "incidental findings" - results that were not expected from the injury - and categorizes them by urgency.

Study shows anorexia linked to how cholesterol processes

The largest DNA-sequencing study of anorexia nervosa has linked the eating disorder to variants in a gene coding for an enzyme that regulates cholesterol metabolism. The finding suggests that anorexia could be caused in part by a disruption in the normal processing of cholesterol, which may disrupt mood and eating behavior.

Genetic analysis of intestinal bacteria shows Danes have 40% less gut bacteria genes

All people have trillions of bacteria living in their intestines. If you place them on a scale, they weigh around 1.5 kg. Previously, a major part of these 'blind passengers' were unknown, as they are difficult or impossible to grow in laboratories.

Personality may be key to genetics of bipolar disorder

People with bipolar disorder vary significantly from their unaffected relatives, and from healthy controls, on several measures of personality, a study shows.

Study: Structural defect in skin cells can contribute to allergy development

In a new study published in Nature Genetics, Northwestern Medicine and Tel Aviv University scientists have found that a structural defect in skin cells can contribute to allergy development, including skin and food allergies, traditionally thought primarily to be a dysfunction of the immune system.

New test hints 3 sodas daily hurt lifespan, reproduction in mice

When mice ate a diet of 25 percent extra sugar - the mouse equivalent of a healthy human diet plus three cans of soda daily - females died at twice the normal rate and males were a quarter less likely to hold territory and reproduce, according to a toxicity test developed at the University of Utah.

Study: Strain of bacteria infections in humans originally come from cattle

A strain of bacteria that causes skin and soft tissue infections in humans originally came from cattle, according to a study to be published in mBio-, the online open-access journal of the American Society for Microbiology.

Study of childhood epilepsies links two new genes to severe forms of disease

A genetic study of childhood epilepsies has linked two new genes to severe forms of disease and provides a novel strategy for identifying therapy targets. This study used a cutting-edge genetic technique, called exome sequencing, to search for new mutations that are not inherited.

Study shows CMEs can predict risk of cancer in type 2 diabetes patients

Certain chromosomal abnormalities of the preleukemic type appear to be over-represented in patients with type 2 diabetes (T2D) who are suffering from vascular complications. This finding may provide a partial explanation for the higher rates of cancer-related mortality observed among patients with this type of diabetes.
