Can ‘toxic’ bilirubin treat a variety of illnesses?
Generations of medical and biology students have been instilled with a dim view of bilirubin. Spawned when the body trashes old red blood cells, the molecule is harmful refuse and a sign of illness. High blood levels cause jaundice, which turns the eyes and skin yellow and can signal liver trouble. Newborns can’t process the compound, and although high levels normally subside, a persistent surplus can cause brain damage.
Yet later this year up to 40 healthy Australian volunteers may begin receiving infusions of the supposedly good-for-nothing molecule. They will be participating in a phase 1 safety trial, sponsored ...

The final puff: Can New Zealand quit smoking for good?
Smoking kills. Ayesha Verrall has seen it up close. As a young resident physician in New Zealand’s public hospitals in the 2000s, Verrall watched smokers come into the emergency ward every night, struggling to breathe with their damaged lungs. Later, as an infectious disease specialist, she saw how smoking exacerbated illness in individuals diagnosed with tuberculosis and HIV/AIDS. She would tell them: “The best thing you can do to promote your health, other than take the pills, is to quit smoking.”
Verrall is still urging citizens to give up cigarettes—no longer just one by one, but by the thousands. As New...

Tissue plasminogen activator promotes white matter integrity and functional recovery in a murine model of traumatic brain injury Neuroscience
Recombinant tissue plasminogen activator (tPA) is a Food and Drug Administration-approved thrombolytic treatment for ischemic stroke. tPA is also naturally expressed in glial and neuronal cells of the brain, where it promotes axon outgrowth and synaptic plasticity. However, there are conflicting reports of harmful versus neuroprotective effects of tPA in...

Hope for reversing stroke-induced long-term disability
Permanent brain damage from a stroke may be reversible thanks to a developing therapeutic technique, a study has found. The novel approach combines transplanted human stem cells with a special protein that the US Food and Drug Administration already approved for clinical studies in new stroke patients. The researchers say they are the first to use 3K3A-APC to produce neurons from human stem cells grafted into the stroke-damaged mouse brain.

Ritalin Could Trigger Heart Problems In Children
Ritalin and similar forms of ADHD medication may trigger abnormal heart rhythms and increase heart attack risk in some children soon after they start taking the drug, according to a new study.
This connection was especially true for children who were born with heart disease.
According to the study, published in the British medical journal BMJ, kids had an increased risk of heart attack between eight and 56 days after starting methylphenidate, a stimulant most commonly sold as Ritalin, although this heightened risk didn’t reach statistical significance. The researchers could find no evidence of a heightened...

Stroke recovery in mice improved by Ambien, study shows
Mice that had strokes rebounded significantly faster if they received low doses of a popular sleeping aid, according to researchers. Zolpidem, better known by the trade name Ambien, has long been approved by the U.S. Food and Drug Administration for treating insomnia. But it has never before been definitively shown to enhance recovery from stroke.

Can You Think Yourself Into A Different Person?
For years she had tried to be the perfect wife and mother but now, divorced, with two sons, having gone through another break-up and in despair about her future, she felt as if she’d failed at it all, and she was tired of it. On 6 June 2007 Debbie Hampton, of Greensboro, North Carolina, took an overdose of more than 90 pills – a combination of ten different prescription drugs, some of which she’d stolen from a neighbor’s bedside cabinet. That afternoon, she’d written a note on her computer: “I’ve screwed up this life so bad that there is no place here for me and nothing I can contr...

Testosterone replacement products boost heart attack, stroke risk, FDA says
The Food and Drug Administration has ordered the makers of testosterone replacement products, which have been aggressively marketed to men with symptoms of low energy and libido, to bear a warning that there is a "possible increased risk of heart attack and strokes" in patients taking the...

Testosterone Drugs May Be Overused, FDA Warns
WASHINGTON (AP) — The Food and Drug Administration is warning doctors against over-prescribing testosterone-boosting drugs for men, saying the popular treatments have not been established as safe or effective for common age-related issues like low libido and fatigue.
The agency says drugmakers must clearly state in their labeling and promotions that the drugs, currently taken by millions of U.S. men, are only approved to treat low testosterone levels caused by disease or injury, not normal aging. Additionally, the FDA cautioned that the drugs may increase the risk of heart attack, stroke and other cardiovascular problem...

Development of the Trevo ProVue Retriever for intracranial clot removal in acute ischemic stroke
It is estimated that 15 million people worldwide have a stroke each year. Of the estimated 795,000 strokes that occur in the United States annually, the majority are ischemic strokes resulting from an obstruction within a vessel supplying blood to the brain. The treatment goal for these patients is to restore blood flow as quickly as possible. Increasingly, endovascular treatments that interact directly with the clot are being pursued as options. Receiving U.S. Food and Drug Administration clearance in 2012, the Trevo® Retriever is a stent‐like structure to be deployed at the site of an occlusion to allow the occluding ...

FDA approves many drugs that predictably increase heart, stroke risk
The agency charged to protect patients from dangerous drug side effects needs to be more vigilant when it comes to medications that affect blood pressure. A clinical professor of family medicine has issued this call to the Food and Drug Administration. At issue is the apparent disconnect between what patients and doctors might consider "clinically significant" risk and the standards that some FDA reviewers apply when evaluating the safety of new therapeutics.

Families face battle with GSK over dangerous diabetes drug
Exclusive: Pharmaceutical giant resists claims despite settlement with victims in USThousands of families in the UK could be deprived of compensation for the death or harm of a relative caused by the diabetes drug Avandia, even though the British maker has agreed to pay billions of dollars to settle similar claims in the US.The licence for Avandia was revoked in Europe, in September 2010, because of evidence that it could cause heart failure and heart attacks. The drug can still be prescribed in the US, but not to patients at risk of heart problems.A scientist with the Food and Drug Administration estimated that Avandia co...

Stem Cells for Cell-Based Therapies
The world of stem cells
We know the human body comprises many cell types (e.g., blood cells, skin cells, cervical cells), but we often forget to appreciate that all of these different cell types arose from a single cell—the fertilized egg. A host of sequential, awe-inspiring events occur between the fertilization of an egg and the formation of a new individual:
Embryonic stem (ES) cells are also called totipotent cells.
The first steps involve making more cells by simple cell division: one cell becomes two cells; two cells become four cells, etc.
Each cell of early development is undifferentiated; that is, it is...
