From fertilisation to birth, an outline guide to a typical pregnancy and how the baby develops inside the womb.

A synthetic version of a naturally occurring peptide promoted the creation of new blood vessels and repaired damaged nerve cells in lab animals, according to researchers.

Researchers are developing new computer-derived models of drugs that might affect chronic pain -- such as pain from backaches, sore limbs and arthritis -- which are targeted for calcium channels.

Researchers have zeroed in on a protein that may play a role in the progression of Alzheimer's disease. The team found that increasing levels of the protein prevented the accumulation of an enzyme linked to Alzheimer's. The strategy may lead to new treatments for the neurodegenerative disease.

A defective, mutant strain of the bacterium that causes gum disease could provide a clue to potential treatments for Alzheimer's, Parkinson's and a number of other diseases.

Neurobiology researchers report they've identified a nervous system pathway that runs parallel to brainstem locomotion command circuitry in vertebrates. Biologists say the finding may suggest new ways for treating symptoms of Parkinson's disease.

Although caffeine is the most widely consumed psychoactive drug worldwide, its potential beneficial effect for maintenance of proper brain functioning has only recently begun to be adequately appreciated. Substantial evidence from epidemiological studies and fundamental research in animal models suggests that caffeine may be protective against the cognitive decline seen in dementia and Alzheimer's disease.

New findings reveal treatment of the most common heart rhythm disorder that affects more than two million Americans significantly reduces the risk of stroke, mortality, Alzheimer's disease and other forms of dementia.

Researchers have identified clinical characteristics associated with prescription drug use disorder in primary care patients with chronic pain. The study found that by identifying characteristics of prescription drug abuse, primary care clinicians can identify those at risk and provide appropriate treatment.

A telephone survey of more than 4,800 people in Michigan found that only a fraction of them would call 9-1-1 if they recognized symptoms of a stroke. Many people said they'd take patients to the hospital but wouldn't call 9-1-1, which is recommended by the American Stroke Association and other health agencies.
