Avocado oil protects against free radicals in mitochondria

Atmospheric oxygen facilitated the evolution and complexity of terrestrial organisms, including human beings, because it allowed nutrients to be used more efficiently by those organisms, which in turn were able to generate more energy. However, as we find out more about how oxygen molecules work inside the body, more attention is being paid to their not-so-good effects, and researchers are seeking ways to thwart them.

Preliminary data hint at how neem extracts may stop replication of HIV virus

Tall, with dark-green pointy leaves, the neem tree of India is known as the "village pharmacy." As a child growing up in metropolitan New Delhi, Sonia Arora recalls on visits to rural areas seeing villagers using neem bark to clean their teeth. Arora's childhood memories have developed into a scientific fascination with natural products and their power to cure illnesses.

APS honors MCW professor with Henry Pickering Bowditch Lecture Award

High blood pressure, or hypertension, is a major problem worldwide, with the latest estimates suggesting that a billion people across the globe may have this condition. Hypertension not only takes an enormous cost on health and wellbeing, but it also exacts an expensive financial toll. Complications from this condition including kidney disease, and its resulting treatments, such as long-term dialysis and kidney transplant, are some of the costliest conditions the American health care system must contend with.

Study shows how cocaine changes the shape and size of neuron rewards in mouse model

New research from Mount Sinai Medical Center in New York reveals that repeated exposure to cocaine decreases the activity of a protein necessary for normal functioning of the brain's reward system, thus enhancing the reward for cocaine use, which leads to addiction. Investigators were also able to block the ability of repeated cocaine exposure, to induce addiction.

Data from 2 new studies on RHD presented at World Congress of Cardiology

Widespread screening of children in poorer countries is now being studied and is resulting in the diagnosis of rheumatic heart disease (RHD) in patients that would likely have gone undetected under normal circumstances, according to two new studies carried out in Fiji and Uganda presented today at the World Congress of Cardiology.

Brain freeze may share common mechanism with other types of headaches

'Brain freeze' is a nearly universal experience—almost everyone has felt the near-instantaneous headache brought on by a bite of ice cream or slurp of ice-cold soda on the upper palate. However, scientists are still at a loss to explain this phenomenon. Since migraine sufferers are more likely to experience brain freeze than people who don't have this often-debilitating condition, brain freeze may share a common mechanism with other types of headaches, including those brought on by the trauma of blast-related combat injuries in soldiers.

Estrone provides anti-inflammatory and antioxidant capabilities after TBI

With more than 1.7 million people sustaining a traumatic brain injury each year, the need to identify processes to limit inflammation and subsequent damage is critical. Approximately 275,000 people are hospitalized annually with traumatic brain injury, leaving 85,000 with long-term disabilities and taking the lives of more than 50,000. More than 5 million people live with disabilities caused by traumatic brain injuries, often the result of car accidents and falls. Direct and indirect costs exceed $75 billion.

HBO2 therapy can reduce neuropathic pain

Chronic pain affects about 76 million people in the U.S. and carries an economic burden of nearly $100 billion annually. The most frequently used medications, narcotic and non-narcotic analgesic drugs (e.g., morphine, ibuprofen, etc.), do not provide complete or sustained relief of chronic pain. Scientists are currently seeking alternative solutions for chronic pain management.

SUMO protein regulates transfer of information between nerve cells in the brain

A key protein, which may be activated to protect nerve cells from damage during heart failure or epileptic seizure, has been found to regulate the transfer of information between nerve cells in the brain. The discovery, made by neuroscientists at the University of Bristol and published in Nature Neuroscience and PNAS, could lead to novel new therapies for stroke and epilepsy.

Orrin Hatch to face primary battle: Health care record on GOP voters' minds

Beating back a challenge from tea party activists, Sen. Orrin Hatch of Utah easily qualified for the Republican primary ballot in his quest for a seventh Senate term Saturday, but he fell just short of winning the GOP nomination outright. ... Mr. Hatch's vote total Saturday marked a stark contrast with the fate of his erstwhile Utah Republican colleague, former Sen. Robert Bennett. ... The senator Hatch also trained his fire on FreedomWorks, the small-government, conservative organization that organized opposition to the senator.
