Researchers investigate unique features of arcuate neurons in the hypothalamus

Maintaining a healthy body weight may be difficult for many people, but it's reassuring to know that our brains and bodies are wired to work together to do just that-in essence, to achieve a phenomenon known as energy balance, a tight matching between the number of calories consumed versus those expended. This careful balance results from a complex interchange of neurobiological crosstalk within regions of the brain's hypothalamus, and when this "conversation" goes awry, obesity or anorexia can result.

Mouse model may provide clues on mechanism that links diabetes and aging to Alzheimer's

Growing evidence suggests that there may be a link between diabetes and Alzheimer's disease, but the physiological mechanisms by which diabetes impacts brain function and cognition are not fully understood. In a new study published in Aging Cell, researchers at the Salk Institute for Biological Studies show, for the first time, that diabetes enhances the development of aging features that may underlie early pathological events in Alzheimer's.

Pfizer receives FDA approval for Synribo to treat chronic myelogenous leukemia

The U.S. Food and Drug Administration today approved Synribo (omacetaxine mepesuccinate) to treat adults with chronic myelogenous leukemia (CML), a blood and bone marrow disease.

Study describes how Dbr1 gene halts toxic buildup of TDP-43-a protein

Scientists at the Gladstone Institutes and the Stanford University School of Medicine have discovered how modifying a gene halts the toxic buildup of a protein found in nerve cells. These findings point to a potential new tactic for treating a variety of neurodegenerative conditions, including amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease)-a fatal disease for which there is no cure.

Combined antimicrobial and light therapy effective for treating foot ulcers

Results from a phase II study show that antimicrobial photodynamic therapy is significantly more effective than placebo for treating patients with chronic leg ulcers.

Researchers figure out 3D shape of promising TB drug target

Researchers at Johns Hopkins have figured out the three-dimensional shape of the protein responsible for creating unique bonds within the cell wall of the bacteria that cause tuberculosis. The bonds make the bacteria resistant to currently available drug therapies, contributing to the alarming rise of these super-bacteria throughout the world.

Researchers identify genes that control regeneration of the intestine in planarian flatworms

Researchers report in the journal Developmental Cell that they have identified genes that control growth and regeneration of the intestine in the freshwater planarian Schmidtea mediterranea.

New federal funding enables researchers to unravel how humans develop cancers

A Simon Fraser University scientist working at one of Canada's first epigenomics mapping centres says new federal funding will accelerate researchers' ability to unravel how we develop some of the most common life threatening cancers.

Associated Press examines access to antiretroviral treatment in Myanmar

The Associated Press examines access to antiretroviral treatment in Myanmar, which "ranks among the world's hardest places to get HIV care, and health experts warn it will take years to prop up a broken health system hobbled by decades of neglect."

mTor molecule plays a significant role in myeloid differentiation

University of Illinois cell and developmental Biology professor Fei Wang and colleagues have created a new technique to study how myeloids, a type of blood stem cell, become the white blood cells important for immune system defense against infections and tissue damage.

Resveratrol does not appear to offer metabolic benefits in healthy women

Resveratrol, an ingredient in red wine thought to improve insulin sensitivity, reduce risk of heart disease and increase longevity, does not appear to offer these benefits in healthy women, new research at Washington University School of Medicine in St. Louis indicates.

NHCS researchers develop human heart cell model of ARVC

Researchers at the National Heart Centre Singapore (NHCS) have successfully created a human heart cell model of arrhythmogenic right ventricular cardiomyopathy (ARVC), an inherited heart muscle disorder which puts one at high risk of developing life-threatening arrhythmias and sudden cardiac death.

Human Gene Therapy articles describe two novel anti-tumor therapies

Targeted T-cells can seek out and destroy tumor cells that carry specific antigen markers. Two novel anti-tumor therapies that take advantage of this T-cell response are described in articles published in Human Gene Therapy, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Video-article details new laser-activated bio-adhesive polymer

A new video-article in JoVE, Journal of Visualized Experiments, details the use of a new laser-activated bio-adhesive polymer. The chitosan-based polymer, SurgiLux, was developed by scientists at the University of New South Wales.

CTCtrap can capture circulating tumour cells in cancer patients

The 7.5 millilitres of blood contained in a standard sample tube is not nearly enough to detect circulating tumour cells (CTCs) in the blood of patients with metastatic breast cancer, prostate cancer, or colorectal cancer with a high enough degree of reliability. These CTCs are the cause of metastases in cancer patients. If they can be effectively characterized, it is possible to arrive at a prognosis and to determine the most effective course of treatment.

CUMC researchers develop first true mouse model of typhoid infection

Columbia University Medical Center (CUMC) researchers have created the first true mouse model of typhoid infection. The development promises to advance the study of typhoid and the creation of new vaccines against the infection, which remains a major health threat in developing countries.

Study identifies essential mechanism that regulates calcium flow into mitochondria

Most healthy cells rely on a complicated process to produce the fuel ATP. Knowing how ATP is produced by the cell's energy storehouse - the mitochondria -- is important for understanding a cell's normal state, as well as what happens when things go wrong, for example in cancer, cardiovascular disease, neurodegeneration, and many rare disorders of the mitochondria.

Jefferson researchers to investigate mechanisms involved in nephrogenic systemic fibrosis

Researchers at the Jefferson Institute of Molecular Medicine were awarded almost $384,000 by the National Institutes of Health to investigate the mechanisms involved in the development of a serious and sometimes fatal disease, known as Nephrogenic Systemic Fibrosis, a rare skin disorder linked to Gadolinium-based contrast agents used in magnetic resonance (MRI and MRA) studies.

Artificial CSP proteins reduce S. pneumoniae competence y more than 90%

The bacterium Streptococcus pneumoniae - which can cause pneumonia, meningitis, bacteremia and sepsis - likes to share its antibiotic-defeating weaponry with its neighbors. Individual cells can pass resistance genes to one another through a process called horizontal gene transfer, or by "transformation," the uptake of DNA from the environment.

HCFC1 protein may cause intellectual disability

Genetics researchers at the University of Adelaide have solved a 40-year mystery for a family beset by a rare intellectual disability - and they've discovered something new about the causes of intellectual disability in the process.
