In a pair of landmark studies that exploit the genetic sequencing of the “missing link” cold virus, rhinovirus C, scientists have constructed a 3-D model of the pathogen that shows why there is no cure yet for the common cold.
Mice models of Alzheimer's treated with one abdominal injection of an antibody fragment designed by researchers showed, after only five days, improved memory and ability to learn as the result of less aggregated toxins and an increase in the number of neurons.
The considerable diversity of HIV worldwide represents a critical challenge for designing an effective HIV vaccine. Now, a scientific team has shown that bioinformatically optimized HIV vaccine antigens might be useful in the design of a global HIV vaccine.
A novel combination of two oral targeted drugs dramatically slowed the growth of glioblastoma brain tumors in mice and significantly extended the animals’ survival, scientists report.
Researchers have published the most comprehensive review of the benefits and risks of a daily dose of prophylactic aspirin and warn that greater understanding of side effects is needed.
A promising technique for treating human eye disease has proven effective in preclinical studies and may lead to new treatments to prevent blindness, according to new experiments.
To overcome triple negative breast cancer's eventual resistance to drugs, chemical engineers have designed nanoparticles that now only carry a cancer drug, but also carry short strands of RNA that can shut off one of the genes that cancer cells use to escape the drug.
Researchers have created a massive online database that matches thousands of genes linked to cancer and other diseases with various drugs that target those genes.
Scientists have identified a set of compounds that may be used to treat MS in a new way: by boosting a population of progenitor cells that can in turn repair MS-damaged nerve fibers.
Often deadly “triple-negative” breast cancers might be effectively treated in many cases with a drug that targets a previously unknown vulnerability in the tumors, according to a new study. Researchers found blocking cystine from entering triple-negative breast cancer cells can significantly inhibited their growth in culture and when the cancer cells were transplanted into mice.
Hold your nose and don't spit out your coffee: Doctors have found a way to put healthy people's poop into pills that can cure serious gut infections - a less yucky way to do "fecal transplants." Canadian researchers tried this on 27 patients and cured them all after strong antibiotics failed to help.
The longest, most comprehensive follow-up yet of women given hormone pills during landmark government research found many health risks faded and some unexpected benefits emerged, but advice remains unchanged: Use hormones only short term if needed to relieve hot flashes and other menopause symptoms.
Engineers have developed a new type of nanoparticle that protects a vaccine long enough to generate a strong immune response— not only in the lungs, but also in mucosal surfaces far from the vaccination site, such as the gastrointestinal and reproductive tracts.
Clinicians should be extra vigilant when prescribing antidepressants as they could pose a risk of type 2 diabetes, researchers have warned. A systematic review showed that people taking antidepressants are at a higher risk of type 2 diabetes.
Abiraterone acetate, a recently FDA-approved drug used to treat men with metastatic castration-resistant prostate cancer and marketed as Zytiga, significantly delays progression of pain and quality of life deterioration when taken in conjunction with prednisone. The design of the study emphasized the importance of patient reported-outcomes in evaluating new treatments.
Working with mice, researchers have discovered that weeks of treatment with a repurposed FDA-approved drug halted the growth of— and ultimately left no detectable trace of— brain tumor cells taken from adult human patients. The scientists targeted a mutation in the IDH1 gene first identified in human brain tumors called gliomas by a team cancer researchers in 2008.
Working with cells in test tubes and in mice, researchers have discovered that a chemical commonly used as a dog food preservative may prevent the kind of painful nerve damage found in the hands and feet of four out of five cancer patients taking the chemotherapy drug Taxol.
It happens too often: A doctor isn't sure what's causing someone's feverish illness but prescribes antibiotics just in case, drugs that don't work if a virus is the real culprit. Now, Duke University researchers are developing a blood test to more easily tell when a respiratory illness is due to a virus and not a bacterial infection, hoping to cut the dangerous overuse of antibiotics and speed the right diagnosis.
The top doctor for Green Berets and other elite Army commandos has told troops to immediately stop taking mefloquine, an anti-malaria drug found to cause permanent brain damage in rare cases. The ban among special operations forces is the latest development in a long-running controversy over over mefloquine.
A research team has shown scientifically what many women report anecdotally: that the breast cancer drug tamoxifen is toxic to cells of the brain and central nervous system, producing mental fogginess similar to “chemo brain.” The researchers also report they’ve discovered an existing drug compound that appears to counteract or rescue brain cells from the adverse effects of the breast cancer drug.
Scientists have found a way to make dramatic improvements to the cancer cell-killing power of vinblastine, one of the most successful chemotherapy drugs of the past few decades. The team’s modified versions of vinblastine showed 10 to 200 times greater potency than the clinical drug.
Researchers from Columbia University Medical Center, working with collaborators at the Hospital for Special Surgery, created a fleet of “nano-robots” that can home in on specific cells and mark them with a fluorescent tag for drug therapy or destruction.
For the first time, the government is estimating how many people die from drug-resistant bacteria each year - more than 23,000, or about as many as those killed annually by flu. The Centers for Disease Control and Prevention released the number to spotlight the growing threat of germs that are hard to treat because they've become resistant to drugs.
The reasons behind why it often takes people several weeks to feel the effect of newly prescribed antidepressants remains somewhat of a mystery– and likely, a frustration to both patients and physicians. Researchers have been working to find out why and if there is anything that can be done to shorten the time in which antidepressants kick in.
Using large and frequent doses of the painkiller codeine may actually produce heightened sensitivity to pain, without the same level of relief offered by morphine, according to new research. The study is believed to be the world's first experimental study comparing the pain relieving and pain worsening effects of both codeine and morphine.
