Tiny particles filled with a drug could be a new tool for treating cancer in the future. A new study published by Swedish scientists in Particle & Particle Systems Characterization shows how such nanoparticles can be combined to secure the effective delivery of cancer drugs to tumour cells – and how they can be given properties to make them visible in MR scanners and thus rendered trackable.

PASADENA, Calif., Feb. 27, 2013 – Patients with diabetes who undergo total knee replacement surgery do not have increased risk of surgical complications compared to those patients without diabetes, according to a Kaiser Permanente study published today in The Journal of Bone and Joint Surgery.
CSIC researcher Maxi San Miguel, director of the Institute for Cross-Disciplinary Physics and Complex Systems (IFISC), a joint research Institute of CSIC and the University of the Balearic Islands, explains: "We say there is a conflict when there is an unusual high number of editing and corrections in articles related to some topic or personage on which there are very divergent or polarised opinions.
At the Faculty of Pharmacy of the Basque Public University (UPV/EHU) the Pharmacokinetics, Nanotechnology and Gene Therapy research team is using nanotechnology to develop new formulations that can be applied to drugs and gene therapy.Specifically, they are using nanoparticles todesignsystems for delivering genes and drugs; this helps to get the genes and drugs to the point of action so that they can produce the desired effect.
Philadelphia, Pa. (February 28, 2013) – Performed an average of a decade after initial facelift surgery, a "secondary" facelift can achieve similarly lasting results with a low complication rate, according to a paper in the March issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).
Cockroaches (Blattodea) are an insect order remarkable in their biodiversity and distribution, with more than 4500 species known and great geographical reach. Cockroach fossils date back around 400 million years, which testifies to their great adaptability and endurance that puts them among the planet's great survivors.
A team of researchers has identified three new distinct overstretched deoxyribonucleic acid (DNA) structures caused by mechanical stretching. This discovery provides a clear answer to a long-running debate among scientists over the nature of DNA overstretching.
Debate on Possible DNA Structural Transitions
ROCHESTER, Minn. — Patients with pneumonia may spend fewer days in the hospital if they are given steroids along with antibiotics and supportive care. That's the finding of a Mayo Clinic analysis of eight randomized-controlled clinical trials involving more than 1,100 patients. The results appear in the March issue of the Journal of Hospital Medicine.
A European study published in the 'Cancer Epidemiology, Biomarkers & Prevention' journal has analysed the association between physical activities and in situ or non-invasive breast cancer, or, in other words, cancer that has not yet invaded cells within or outside of the breast.
Headed by researchers from ten European countries including Spain, the work carried out under the framework of the European Prospective Investigation into Cancer and Nutrition (EPIC) concludes that physical activity has no relation with the risk of developing this type of non-invasive cancer.
Strains of potentially deadly, antibiotic-resistant Staphylococcus aureus bacteria show seasonal infection preferences, putting children at greater risk in summer and seniors at greater risk in winter, according to results of a new nationwide study led by a Johns Hopkins researcher.
It's unclear why these seasonal and age preferences for infection with methicillin-resistant Staph aureus (MRSA) occur, says Eili Klein, Ph.D., lead author on the study and a researcher at the Johns Hopkins Center for Advanced Modeling in the Social, Behavioral and Health Sciences.
Bethesda, MD—Women who are pregnant or using synthetic progesterone birth control injections have a conspicuous vulnerability to certain infections including malaria, Listeria, HIV, and herpes simplex virus. A new research report appearing in the March 2013 issue of the Journal of Leukocyte Biology offers strong evidence for a possible explanation: the progesterone receptor, a pregnancy hormone sensor, targets a part of the immune system responsible for protection against these and other invaders.
Bethesda, MD—Earth Day may be more than a month away, but another, more personal, ecosystem has been shown to also be worth protecting—within our bodies are communities of microbes that affect the behavior of human cells hosting them. These communities, called the "microbiome," is so crucial to our health that some consider it to be a complex "second genome." Understanding the interaction of these microbes among one another and their human hosts has the potential to yield insights into numerous diseases and complex human disorders from obesity to susceptibility to infection.
The bacteria that cause acne live on everyone's skin, yet one in five people is lucky enough to develop only an occasional pimple over a lifetime. What's their secret?
In a boon for teenagers everywhere, a UCLA study conducted with researchers at Washington University in St. Louis and the Los Angeles Biomedical Research Institute has discovered that acne bacteria contain "bad" strains associated with pimples and "good" strains that may protect the skin.
Cincinnati, OH, February 28, 2013 -- Although the long-term consequences of childhood obesity are well documented, some school districts have reduced physical education classes to devote more time to the 3 Rs in education—reading, writing, and arithmetic. However, there is new evidence that leaving out an important fourth R—aerobics—could actually be counterproductive for increasing test scores.
