In blood vessel stents, innovative materials allow better control, delivery of gene therapy
Before gene therapy becomes practical for treating human diseases, researchers must master the details of safe and effective delivery. view more (2008-04-16)
HIV drug resistance is increasing in the UK
The prevalence of transmitted HIV drug resistance in the United Kingdom is increasing, according to a study in this week's BMJ. This finding emphasises the urgent need for new approaches to encourage safer sexual behaviour. A total of 69 patients infected with HIV between June 1994 and August 2000 were evaluated for resistance within 18 months of... view more... (2001-05-02)
Drug users unaware of memory problems
Ecstasy and cannabis do impair memory - but regular users don't think so. view more (1999-03-26)
Diabetics to benefit as clinical chemistry gets under the skin
Water makes up more than 70 percent of our bodies, and our skin works like an oily film providing an effective barrier to keep water and the other charged substances inside us. But skin is not an impermeable material, and charged substances from inside the body can be made to cross the skin barrier by applying an electric field. Iontophoresis is a... view more...

Nanotechnology holds promise for STD drug delivery
Yale researchers describe a breakthrough in safe and effective administration of potential antiviral drugs - small interfering RNA (siRNA) molecules that silence genes - the first step in development of a new kind of treatment for sexually transmitted diseases (STDs). view more (2009-05-04)
Prescription opioids the predominant choice among illicit opioid users
For almost a century, heroin addiction has been a core element of the illicit drug use problem in Canada. Recently, however, isolated reports have pointed to substantial increases in prescription opioid abuse. view more (2006-11-21)
New study shows epidural during birth may negatively affect breastfeeding
Epidurals given during labour and birth are associated with decreased rates of breastfeeding, both in the short and long term. view more (2006-12-11)
Random drug testing in schools is unworkable
Random drug testing in schools is unworkable because schools could not satisfy government criteria for introducing new screening programmes, claims a public health expert in this week's BMJ. The Department of Health has 19 criteria for introducing new screening programmes. At least 18 of these are not met for widespread drug urine analysis in... view more... (2004-03-10)
Gene therapy appears safe to regenerate gum tissue
Scientists at the University of Michigan have developed a method of gene delivery that appears safe for regenerating tooth-supporting gum tissue-a discovery that assuages one of the biggest safety concerns surrounding gene therapy research and tissue engineering. view more (2009-04-08)
UCSB researchers discover shape matters to macrophages
Researchers at UC Santa Barbara have made a surprising discovery: phagocytosis depends more on particle shape than size. view more (2006-03-22)
HIV drug resistance risk in mothers reduced by combination of common drugs
New research from the University of Alabama at Birmingham (UAB) shows that adding a single dose of two common anti-HIV drugs can prevent HIV-positive pregnant women from developing resistance to an entire class of drugs, potentially improving future treatment options. view more (2007-11-12)
Cell discovery opens new chapter in drug development
British scientists have uncovered new details about how the cells in our bodies communicate with each other and their environment: findings that are of fundamental importance to human biology. view more (2009-09-09)
Carbon nanotube membranes allow super-fast fluid flow
Membranes composed of manmade carbon nanotubes permit a fluid flow nearly 10,000 to 100,000 times faster than conventional fluid flow theory would predict because of the nanotubes' nearly friction-free surface. view more (2005-11-04)
Pairing Nanoparticles with Proteins
In groundbreaking research, scientists have demonstrated the ability to strategically attach gold nanoparticles - particles on the order of billionths of a meter - to proteins so as to form sheets of protein-gold arrays. view more (2007-06-28)
Weighting cancer drugs to make them hit tumors harder
Scientists have devised a blueprint for boosting anti-cancer drugs' effectiveness and lowering their toxicity by attaching the equivalent of a lead sinker onto the drugs. view more (2006-03-03)
U of M researchers discover new method to combat HIV
Researchers at the University of Minnesota's Center for Drug Design have developed a new method to combat HIV/AIDS, potentially replacing the traditional cocktail drug approach. view more (2007-07-24)
Garlic chemical tablet treats diabetes I and II
A drug based on a chemical found in garlic can treat diabetes types I and II when taken as a tablet, a study in the new Royal Society of Chemistry journal Metallomics says. view more (2008-11-20)
European Microbiologists to discuss Bioterrorism at the 1 st FEMS Congress in Slovenia
Whatever the outcome of the search for weapons of mass destruction in Iraq or elsewhere the use of biological agents as weapons of terrorist war will be an ever-present threat in the future. "Dealing with the threat from bioterrorism" is the title of one of the discussions to be held at the 1st FEMS Congress of European Microbiologists... view more... (2003-05-21)
New Hybrid Nanostructures Detect Nanoscale Magnetism
A key challenge of nanotechnology research is investigating how different materials behave at lengths of merely one-billionth of a meter. When shrunk to such tiny sizes, many everyday materials exhibit interesting and potentially beneficial new properties. view more (2008-12-09)
When antidepressant drugs stop working: A novel approach
Tolerance to antidepressant drug treatment is an important clinical problem (one third of cases). It may manifest as loss of clinical effect (an antidepressant drug which was working stops doing so) or resistance (a patient, after a drug-free period, fails to respond to an antidepressant drug which was effective before). There is no current... view more... (2003-05-06)
