Researchers discover how diabetes affects specific brain area leading to memory loss

Badly controlled diabetes are known to affect the brain causing memory and learning problems and even an increased incidence of dementia, although how this occurs is not clear.

Automated way to record electrical activity inside neurons in the living brain

Gaining access to the inner workings of a neuron in the living brain offers a wealth of useful information: its patterns of electrical activity, its shape, even a profile of which genes are turned on at a given moment. However, achieving this entry is such a painstaking task that it is considered an art form; it is so difficult to learn that only a small number of labs in the world practice it.

Brain networks may avoid traffic jams by communicating on different frequencies

Brain networks may avoid traffic jams at their busiest intersections by communicating on different frequencies, researchers at Washington University School of Medicine in St. Louis, the University Medical Center at Hamburg-Eppendorf and the University of T-bingen have learned.

Cordoning off of lipids of the liver helps manage insulin resistance in the body

A Penn research team, led by Mitchell Lazar, MD, PhD, director of the Institute for Diabetes, Obesity, and Metabolism at the Perelman School of Medicine, University of Pennsylvania, reports in Nature Medicine that mice in which an enzyme called histone deacetylase 3 (HDAC3) was deleted had massively fatty livers, but lower blood sugar, and were thus protected from glucose intolerance and insulin resistance, the hallmark of diabetes.

Eye color linked to high-risk for skin conditions

Eye color may be an indicator of whether a person is high-risk for certain serious skin conditions. A study, led by the University of Colorado School of Medicine, shows people with blue eyes are less likely to have vitiligo.

Researchers make white fat take on characteristics of brown fat

Brown seems to be the color of choice when it comes to the types of fat cells in our bodies. Brown fat expends energy, while its counterpart, white fat stores it. The danger in white fat cells, along with the increased risk for diabetes and heart disease it poses, seems especially linked to visceral fat. Visceral fat is the build-up of fat around the organs in the belly.

Researchers separate low and high-PSA prostate cancer cells

Prostate cancer cells that defy treatment and display heightened tumor-generating capacity can be identified by levels of prostate specific antigen (PSA) expressed in the tumor cells, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports in the May 3 edition of Cell Stem Cell.

New study on curcumin for advanced bowel cancer

Compounds found in curry are being investigated as a way of improving drug response in patients with advanced bowel cancer in a new study launched on Monday.

Accentia, Johns Hopkins co-host meeting with prospective clinical trial investigators at AAN meeting

Accentia Biopharmaceuticals, Inc. today announced that the Company and leading physicians from Johns Hopkins University co-hosted a meeting with prospective clinical trial investigators at the recent American Academy of Neurology (AAN) Annual Meeting in New Orleans.

Human stem cells effective in treating muscular dystrophy

Researchers from the University of Minnesota's Lillehei Heart Institute have effectively treated muscular dystrophy in mice using human stem cells derived from a new process that - for the first time - makes the production of human muscle cells from stem cells efficient and effective.

New system measures strength of communication between muscle cells and motor neurons

In an effort to identify the underlying causes of neurological disorders that impair motor functions such as walking and breathing, UCLA researchers have developed a novel system to measure the communication between stem cell-derived motor neurons and muscle cells in a Petri dish.

Researchers identify new mechanism that causes choroidal neovascularization

Sloppy shipping of a donated human retina to an Indiana University researcher studying a leading cause of vision loss has inadvertently helped uncover a previously undetected mechanism causing the disease. The discovery has led researchers to urge review of how millions of dollars are spent investigating the cause of a type of age-related macular degeneration called choroidal neovascularization.

PDE4 enzyme regulates division of tumour cells and blood vessel growth in cancer tissue

Lung cancer is the leading cause of cancer death throughout the world. Standard treatment methods do not usually result in long-term recovery. In addition to the proliferation of the tumour cells, the growth of blood vessels controls tumors development. The blood vessel growth is controlled by several signalling molecules. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim and Justus Liebig University Giessen have discovered a molecule that plays a key role in this process. They succeeded in reducing tumour growth in their experiments by blocking the phosphodiesterase PDE4.

Inland Empire Stem Cell Consortium to enhance collaboration among three universities

Stem cell research laboratories at the University of California, Riverside, Loma Linda University and the California State University at San Bernardino have formed the "Inland Empire Stem Cell Consortium" to enhance collaboration among the three universities and bring focus to stem cell work being done in inland Southern California.

Research identifies molecular trigger of fibroid uterine tumors

Fibroid uterine tumors affect an estimated 15 million women in the United States, causing irregular bleeding, anemia, pain and infertility. Despite the high prevalence of the tumors, which occur in 60 percent of women by age 45, the molecular cause has been unknown.

Dilp8 provides an important signal to slow body growth and delay insect development

Two independent groups of researchers have identified a hormone that is responsible for keeping the growth and development of insects on track. The results, which are reported in the journal Science, suggest that Dilp8 provides an important signal to slow body growth and delay insect development.

MicroRNAs in breast cancer play a role in development of resistance to tamoxifen

Many breast cancer patients are treated with a drug called tamoxifen. The substance blocks the effect of estrogen and thus suppresses the growth signals of this hormone in cancer cells. When resistance to the drug develops, tumor cells change their growth program: They change their behavior and shape, become more mobile and also adopt the ability to invade surrounding tissue. Scientists working with PD (Associate Professor) Dr. Stefan Wiemann of the German Cancer Research Center (DKFZ) have now also observed these changes in tamoxifen resistant breast cancer cells.

Patterns of brain activity that play a role in recall of memories and decision-making

UCSF scientists have identified patterns of brain activity in the rat brain that play a role in the formation and recall of memories and decision-making. The discovery, which builds on the team's previous findings, offers a path for studying learning, decision-making and post-traumatic stress syndrome.

Awake mental replay essential for making informed choices

Awake mental replay of past experiences is essential for making informed choices, suggests a study in rats. Without it, the animals- memory-based decision-making faltered, say scientists funded by the National Institutes of Health. The researchers blocked learning from, and acting on, past experience by selectively suppressing replay - encoded as split-second bursts of neuronal activity in the memory hubs of rats performing a maze task.
