Magnet guides iron-loaded cells to specific damaged sites in the heart

Optimal stem cell therapy delivery to damaged areas of the heart after myocardial infarction has been hampered by inefficient homing of cells to the damaged site. However, using rat models, researchers in France have used a magnet to guide cells loaded with iron oxide nanoparticles to key sites, enhancing the myocardial retention of intravascularly delivered endothelial progenitor cells.

DHA and curcumin help maintain neurological function after degenerative damage

UCLA researchers discovered that a diet enriched with a popular omega-3 fatty acid and an ingredient in curry spice preserved walking ability in rats with spinal-cord injury. Published June 26 in the Journal of Neurosurgery: Spine, the findings suggest that these dietary supplements help repair nerve cells and maintain neurological function after degenerative damage to the neck.

Gene transfer technique eliminates specific neural circuit linked to Parkinson's disease

In the brains of humans and non-human primates, over 100 billion nerve cells build up complicated neural circuits and produce higher brain functions. When an attempt is made to perform gene therapy for neurological diseases like Parkinson's disease, it is necessary to specify a responsible neural circuit out of many complicated circuits.

Diet enriched with curcumin and DHA can promote neuroprotection in chronic SCI

Researchers from the Department of Neurosurgery at the David Geffen School of Medicine and the Department of Integrative Biology and Physiology at UCLA have found that a diet enriched with docosahexaenoic acid (DHA), an omega-3 fatty acid, and curcumin, a component of the Indian spice turmeric, can protect the injured spinal cord and minimize the clinical and biochemical effects of spinal cord myelopathy in rats.

Scientists now have clues to how GATA4 gene mutation leads to septal defects in babies with CHD

Scientists now have clues to how a gene mutation discovered in families affected with congenital heart disease leads to underdevelopment of the walls that separate the heart into four chambers.

High-calorie food images stimulate brain's appetite control center

A picture may be worth a thousand calories, a new study suggests. Looking at images of high-calorie foods stimulates the brain's appetite control center and results in an increased desire for food, according to the study, which will be presented Monday at The Endocrine Society's 94th Annual Meeting in Houston.

New type of micromachine can penetrate tissue and overcome cellular barriers

Microscopically small submarines that can swim through our blood to clear out clogged arteries or destroy malignant tumors. This concept may sound utopian, but it isn’t. Various micro- and nanomachines have in fact already been developed.

Scientists discover serum biochemical signature that predicts Alzheimer's

Scientists from VTT Technical Research Centre of Finland in collaboration with the University of Eastern Finland have recently discovered a serum biochemical signature which predicts progression to Alzheimer's disease months or even years before the first symptoms of the disease occur. The goal of the new collaboration between VTT and GE Healthcare is to validate this biomarker in a large patient cohort as well as to discover novel biomarker candidates.

Obese children show greater exposure to phthalates

Obese children show greater exposure than nonobese children to a phthalate, a chemical used to soften plastics in some children's toys and many household products, according to a new study, which found that the obesity risk increases according to the level of the chemical found in the bloodstream.

Broken heart syndrome may protect the heart from adrenaline overload

A condition that temporarily causes heart failure in people who experience severe stress might actually protect the heart from very high levels of adrenaline, according to a new study published in the journal Circulation. The research provides the first physiological explanation for Takotsubo cardiomyopathy, also called "broken heart syndrome" because it affects people who suffer severe emotional stress after bereavement, and suggests guidance for treatment.

The Endocrine Society issues Statement of Principles on EDCs and public health protection

In a Statement of Principles unveiled today, The Endocrine Society proposes a streamlined definition for endocrine-disrupting chemicals (EDCs) and offers recommendations that will strengthen the ability of current screening programs to identify EDCs.

Researchers identify latest gene associated with typical late-onset Lewy body Parkinson's

An international team led by human genetic researchers at the University of British Columbia and Vancouver Coastal Health has identified the latest gene associated with typical late-onset Lewy body Parkinson's disease (PD), with the help of a Canadian Mennonite family of Dutch-German-Russian ancestry.

Scientists discover new flu-fighting role for IL-15 protein

University of Georgia scientists have discovered a new flu-fighting role for a well-known component of the immune system. Kimberly Klonowski, assistant professor of cellular biology in the UGA Franklin College of Arts and Sciences, and her colleagues found that administering a cell-signaling protein known as IL-15 to mice infected with influenza reduces their peak viral load by nearly three times.

ESCs and iPSCs demonstrate similar survival and neural differentiation capabilities

Researchers in Japan who evaluated the risks and efficacy of transplanting two varieties of stem cells into mouse cochlea have concluded that both adult-derived induced pluripotent stem (iPS) cells and mouse embryonic stem (ES) cells demonstrate similar survival and neural differentiation capabilities.

Study investigates how glucose metabolism affects biochemical signals in cancer cells

Compared to normal cells, cancer cells have a prodigious appetite for glucose, the result of a shift in cell metabolism known as aerobic glycolysis or the "Warburg effect." Researchers focusing on this effect as a possible target for cancer therapies have examined how biochemical signals present in cancer cells regulate the altered metabolic state.

Prenatal exposure to BPA appears to program uterine estrogen responsiveness in adulthood

Prenatal exposure to bisphenol A, or BPA, a chemical found in many common plastic household items, can cause numerous genes in the uterus to respond differently to estrogen in adulthood, according to a study using a mouse model. The results will be presented Tuesday at The Endocrine Society's 94th Annual Meeting in Houston.
