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.

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.

Soy protein may reduce fat accumulation, triglycerides in the livers of obese persons

University of Illinois scientists report that soy protein may significantly reduce fat accumulation and triglycerides in the livers of obese persons. And they've discovered why it happens: soy restores partial function of that organ's key signaling pathway.

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.

Researchers identify molecular pathway that controls retention, release of the brain's stem cells

Researchers at Columbia University Medical Center (CUMC) have identified a molecular pathway that controls the retention and release of the brain's stem cells.

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.

Study shows how MRSA epidemics may emerge and spread at molecular level

National Institutes of Health (NIH) scientists and their colleagues in China have described a rapidly emerging Staphylococcus aureus gene, called sasX, which plays a pivotal role in establishing methicillin-resistant S. aureus (MRSA) epidemics in most of Asia.

Scientists identify link between different strains of malaria parasites

Scientists have identified a link between different strains of malaria parasites that cause severe disease, which could help develop vaccines or drugs against life-threatening cases of the infection.

Penn researchers continue efforts to differentiate Alzheimer's from FTLD

Teasing out the exact type or types of dementia someone suffers from is no easy task; neurodegenerative brain diseases share common pathology and often co-occur. Researchers from the Perelman School of Medicine at the University of Pennsylvania are continuing efforts to differentiate diseases, such as Alzheimer's disease (AD) from frontotemporal lobar degeneration (FTLD), as FTLD is often clinically difficult to distinguish from atypical presentations of AD.

Scripps Florida scientist to develop new tests for aging and stress-associated diseases

A scientist from the Florida campus of The Scripps Research Institute has been awarded just over $1 million from the National Institutes of Health to develop a range of new tests that could lead to new treatments for a number of stress-associated and degenerative disorders of advancing age.

Scientists discover tumor-targeting neural stem cells

Could engineered human stem cells hold the key to cancer survival? Scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have discovered that neural stem cells possess the innate ability to target tumor cells outside the central nervous system. This finding, which was demonstrated successfully on breast cancer cells, was recently published in leading peer reviewed journal, Stem Cells.
