Researchers identify new mechanism that causes neurodegeneration

As we age, our body rhythms lose time before they finally stop. Breaking the body clock by genetically disrupting a core clock gene, Bmal1, in mice has long been known to accelerate aging , causing arthritis, hair loss, cataracts, and premature death.

Neuroscientists discover new role played by common but mysterious class of brain cells

Stanford University School of Medicine neuroscientists have discovered a new role played by a common but mysterious class of brain cells.

Researchers identify key immune cells that turn body's defenders against invading golden staph

When golden staph enters our skin it can identify the key immune cells and 'nuke' our body's immune response.

Research: Higher BMI liked with increased risk of hearing loss in women

According to the World Health Organization, 360 million people have disabling hearing loss, a condition that is often considered to be an unavoidable side effect of aging.

PCBs banned by the US 3 decades ago hurt seniors' cognitive performance

Although PCBs have been banned in the United States since 1979, University of Montreal and CHU Sainte-Justine researcher Maryse Bouchard has found that higher levels of the toxin was associated with lower cognitive performance in seniors.

Viewpoints: Opposition to Medicaid dooming the South; Obama's 'blank check' for insurers; one woman's quest for coverage

As inapt as those comparisons are, what is distressingly similar today is how the South is once again committed to taking a backward path. By refusing to expand health care for the working poor through Medicaid, which is paid for by the federal government under Obamacare, most of the old Confederacy is committed to keeping millions of its own fellow citizens in poverty and poor health. They are dooming themselves, further, as the Left-Behind States (Timothy Egan, 11/21).

New tool provides first comprehensive guide to optimize ostomy management

Nurses caring for ostomy patients will now be equipped with an essential new tool that provides them with the first comprehensive guide to optimize ostomy management and enhance patient safety.

Younger people with HIV feel more isolated and stressed than older people

Case Western Reserve University researchers were surprised to learn that people younger than 50 years old with HIV feel more isolated and stressed than older people with the disease. They expected their study to reveal just the opposite.

Unemployed men show signs of faster ageing in their DNA

Men who are unemployed for more than two years show signs of faster ageing in their DNA, a new study has found.

Brown University biologists find way to measure effects of aging

Biologists at Brown University have found a way to measure the effects of aging by watching the ebb and flow of chromatin, a structure along strands of DNA that either silences or permits gene expression. In several newly published experiments they show that gene silencing via chromatin in fruit flies declines with age.

Buck Institute research provides method to study sarcopenia

Our epigenome is a set of chemical switches that turn parts of our genome off and on at strategic times and locations. These switches help alter the way our cells act and are impacted by environmental factors including diet, exercise and stress. Research at the Buck Institute reveals that aging also effects the epigenome in human skeletal muscle. The study, appearing on line in Aging Cell, provides a method to study sarcopenia, the degenerative loss of muscle mass that begins in middle age.

Findings show how cancer and aging are tightly interconnected

Researchers from the Geisel School of Medicine at Dartmouth have found that epigenetic changes to DNA are associated with aging in disease-free breast tissues and are further altered in breast tumors. Epigenetic changes describe heritable alterations caused by mechanisms other than by changes in DNA sequence. The discovery, published in the February 2014 issue of Epigenetics, illustrates how cancer and aging are tightly interconnected processes by identifying epigenetic alterations present in the normal aging breast that may increase disease risk in cancer-free individuals.

Researchers discover new human enzyme that facilitates DNA repair during DNA copying process

Every day, the human body produces new cells to regenerate tissues and repair those that have suffered injury. Each time this happens, the cells make copies of their DNA that they will pass on to the resulting daughter cells. This process of copying the DNA, also called replication, is very delicate, given that it can generate severe alterations in the DNA that are associated with malignant transformation or ageing.

Study finds high rate of anisometropia in older adults

Follow-up in older adults shows a high rate of anisometropia, or differing levels of visual abnormalities between eyes, reports a study in Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

University of Sydney researchers identify new type of medication for osteoporosis

University of Sydney researchers have discovered a new and promising treatment for osteoporosis which is easily delivered in water soluble form.

Study shows cognitively impaired older adults released from hospital less likely to be rehospitalized

Cognitively impaired older adults released from the hospital are less likely to be rehospitalized within 30 days if they go to a nursing home than if they return to their own home or the home of a family member, according to an Indiana University and Regenstrief Institute study.

Study confirms therapeutic potential of inhibiting Aurora-A in cancer treatment

Aurora-A is a protein involved in the cell division process that is highly expressed or synthesised in a large number of human cancers, especially in those associated with a bad prognosis. Several pharmaceutical companies have recently developed these protein inhibitors, although the therapeutic and physiological effects that blocking Aurora-A might have on adult tissues are still unknown.

Young adults who had childhood cancer more likely to be frail than their peers

Young adults who survived childhood cancer are more likely than their peers to be frail, according to a St. Jude Children's Research Hospital study, which reported the condition is more common among female survivors than women decades older. The research appears in the November 18 online edition of the Journal of Clinical Oncology.

BIDMC pilot study shows promise for age-related cognitive disorders

It's well known that the brains of meditators change, but it's not entirely clear what those changes mean or how the changes might benefit the meditator. A new pilot study led by researchers at Beth Israel Deaconess Medical Center suggests that the brain changes associated with meditation and stress reduction may play an important role in slowing the progression of age-related cognitive disorders like Alzheimer's disease and other dementias.

Study evaluates effect of structured weight reduction program on atrial fibrillation symptoms

Hany S. Abed, B.Pharm., M.B.B.S., of the University of Adelaide and Royal Adelaide Hospital, Adelaide, Australia and colleagues evaluated the effect of a structured weight reduction program on atrial fibrillation symptoms.
