New method can detect and monitor pH changes in living brains

University of Iowa neuroscientist John Wemmie, M.D., Ph.D., is interested in the effect of acid in the brain. His studies suggest that increased acidity or low pH, in the brain is linked to panic disorders, anxiety, and depression. But his work also suggests that changes in acidity are important for normal brain activity too.

First study to compare complication rates after RAPN and LPN

Robot-assisted surgery has replaced another minimally invasive operation as the main procedure to treat kidney cancer while sparing part of the diseased organ, and with comparable results, according to a new research study by Henry Ford Hospital urologists.

Researchers identify over 2500 mRNA along dendrites and axons

How do we build a memory in the brain? It is well known that for animals (and humans) new proteins are needed to establish long-term memories. During learning information is stored at the synapses, the junctions connecting nerve cells.

IGABT effective at controlling return and spread of cervical cancer

Delivering radiotherapy directly to cancer of the cervix using 3-D imaging techniques is effective at controlling the return and spread of the disease and, in most cases, avoids the need for hysterectomies, according to research presented at the World Congress of Brachytherapy today.

Cellular-level images of the living eye

The same technology used by astronomers to obtain clear views of distant stars is now being used by optometrists to perform incredibly detailed examinations of the living eye.

Seed localization improves satisfaction of breast cancer patients

A cutting-edge procedure called seed localization is improving patient satisfaction at The Dubin Breast Center of the Tisch Cancer Institute at The Mount Sinai Medical Center. In patients undergoing lumpectomy for cancers that are small and cannot be felt in the breast, a tiny radioactive seed is guided into the breast and implanted at the site of the tumor.

Study shows how MRA and CTA are equivalent in delineating anatomy in living renal donors

A new study from UCLA shows how magnetic resonance angiography (MRA) and computed tomography angiography (CTA) are equivalent in delineating anatomy in living renal donors.

New studies on personalized lung cancer treatment presented at 3rd ELCC

Several new studies that may help doctors tailor lung cancer treatment to the characteristics of individual patients and of their tumors are being presented at the 3rd European Lung Cancer Conference in Geneva.

PDAD patients have much denser accumulations of striatal plaques in the brain

Dementia is a frequent complication of Parkinson's disease (PD), but it is clinically impossible to distinguish PD dementia (PDD), which develops from the progression of the Lewy body pathology that underlies PD, from PD with coexistent Alzheimer's disease.

Two research studies on genetic components of Alzheimer's

Two research studies, co-led by UC Davis neurologist Charles DeCarli and conducted by an international team that included more than 80 scientists at 71 institutions in eight countries, has advanced understanding of the genetic components of Alzheimer's disease and of brain development. Both studies appear in the April 15 edition of the journal Nature Genetics.

The key to treating AML may lie within FTL3 gene mutations

The key to treating one of the most common types of human leukemia may lie within mutations in a gene called FLT3, according to new research led by physician-scientists at the University of California, San Francisco (UCSF) Helen Diller Family Comprehensive Cancer Center.

Increasing pressure ejects surplus healthy cells from overcrowded tissues

Cancer Research UK scientists have shown that increasing pressure ejects surplus healthy cells from overcrowded tissues, revealing a possible link between this process and the spread of cancer, according to a study published in Nature.

Study examines potential impact of policies to reduce inappropriate imaging for prostate cancer

In the current hyper-charged United States healthcare debate, the focus on lowering cost without compromising quality of care remains a priority. But according to a new study by researchers at NYU Langone Medical Center and colleagues, one common approach may have serious unintended consequences.

Non-invasive and longitudinal assessment of fat in animal disease models

Researchers are increasingly aware that fat in some parts of the body is more harmful than fat in other places. To help determine how obesity works, scientists turn to animal models and now, they are able to visualize how much fat their lab rats are carrying and where they are storing it.

Deep brain stimulation has long-lasting effects in patients with severe depression

People with severe depression are constantly despondent, lacking in drive, withdrawn and no longer feel joy. Most suffer from anxiety and the desire to take their own life. Approximately one out of every five people in Germany suffers from depression in the course of his/her life - sometimes resulting in suicide. People with depression are frequently treated with psychotherapy and medication.

Scientists image process of consciousness after general anesthesia

Awakening from anesthesia is often associated with an initial phase of delirious struggle before the full restoration of awareness and orientation to one's surroundings. Scientists now know why this may occur: primitive consciousness emerges first. Using brain imaging techniques in healthy volunteers, a team of scientists led by Adjunct Professor Harry Scheinin, M.D. from the University of Turku, Turku, Finland in collaboration with investigators from the University of California, Irvine, USA, have now imaged the process of returning consciousness after general anesthesia.

Altered activity at different sites within brain network may be related to different features of depression

Depressed individuals with a tendency to ruminate on negative thoughts, i.e. to repeatedly think about particular negative thoughts or memories, show different patterns of brain network activation compared to healthy individuals, report scientists of a new study in Biological Psychiatry.

Neural imaging-maps of brain functions hope to transform lives of people with epilepsy

Neural imaging-maps of brain functions-is a primary tool used by researchers hoping to transform the lives of people living with chronic neurological conditions such as epilepsy. At present, researchers often require several different imaging techniques to fully map brain functions, making research and treatment of these conditions expensive and inefficient.

Mammograms may increase risk for ‘over-diagnosis’ of cancers: Study

According to a new study from Norway up to a fourth of breast cancers found through mammograms are harmless and would not cause noticeable disease during the women's lifetimes. Such women are said to be over-diagnosed, because their cancers would not have caused symptoms or death. Over-diagnosis is a problem because women may receive tests and treatment they did not actually need.
