HIV in late childhood and adolescence a growing problem

Scientists have highlighted for the first time the plight of the growing number of older children and adolescents living with undiagnosed HIV and AIDS in Africa. In a study published today in Clinical Infectious Diseases, Wellcome Trust researchers claim that delay in recognising this problem means that the needs of this important group are not being met.

New guidelines on cultivating Artemisia plant used in anti-malaria medicines

The World Health Organization (WHO) has published guidelines for the cultivation and collection of Artemisia (Artemisia annua L., Asteraceae), known in the United States as sweet Annie or annual wormwood, a Chinese traditional medicinal plant which is the source of artemisinin, used to produce the most effective medicines for malaria.

Drug delivery system that consists of nanocrystals of a hydrophobic drug

The problem of efficiently delivering drugs, especially those that are hydrophobic or water-repellant, to tumors or other disease sites has long challenged scientists to develop innovative delivery systems that keep these drugs intact until reaching their targets.

Mayo Clinic tests engineered measles virus against multiple myeloma

Mayo Clinic Cancer Center has opened a new Phase I clinical trial testing an engineered measles virus against multiple myeloma, a cancer of the bone marrow that currently has no cure. This is the third of a series of molecular medicine studies in patients testing the potential of measles to kill cancer.

Translaminar technique reduces neck pain without significant risk of paralysis

In the largest series of patients to date, recent research shows that the translaminar approach to cervical spinal steroid injections can reduce neck pain in eighty-three percent of those treated.

Improvement of cancer-targeting therapy, using nanocarriers for intractable solid tumors by inhibition of TGF-beta signaling

Administering a small amount of a potent but potentially toxic anticancer agent along with nanoparticles loaded with a second anticancer agent produced a dramatic inhibition of tumor growth in normally intractable cancers. These findings suggest a new approach to treating malignancies such as pancreatic cancer and diffuse gastric cancer.

Targeted nanoparticles image early tumors

A well-established fact in cancer therapy is that early tumor detection improves the odds that a patient will survive the disease. Now, using nanoparticles targeted to the tiny blood vessels that surround even the smallest tumors, researchers at the Siteman Center for Cancer Nanotechnology Excellence (CCNE) have developed a radioactive imaging agent that was able to identify human tumors in rabbits.

Erectile dysfunction drugs may be better than nitroglycerin in protecting the heart after a severe heart attack

During a heart attack, the heart is deprived of oxygen, which can result in significant damage to heart muscle and tissue. After the attack, most patients require treatment to reduce and repair the damage and improve their chances of survival.

Surgery, shock waves both effective for removing kidney stones

Two common methods for removing kidney stones - surgery and shock wave treatments - are effective and safe, and neither is clearly superior to the other, researchers report in a new systematic review of studies. But these conclusions aren't based on particularly strong data, the researchers say.

Virtual Iraq to aid traumatised soldiers and military staff

The virtual Iraq simulation, developed at the University of Southern California (USC) but now being put into practice at Reading, is "fully-immersive" and designed as part of an exposure therapy programme which allows soldiers suffering post-traumatic stress disorder to relive and confront psychological trauma - and it has produced promising results for the first handful of patients treated.

Researchers wake up viruses inside tumors to image and then destroy cancers

They say this strategy could offer a novel way of treating many cancers associated with Epstein-Barr, including at least four different types of lymphoma and nasopharyngeal and gastric cancers.

Green tea and COX-2 inhibitors combine to slow growth of prostate cancer

Drinking a nice warm cup of green tea has long been touted for its healthful benefits, both real and anecdotal. But now researchers have found that a component of green tea, combined with low doses of a COX-2 inhibitor, could slow the spread of human prostate cancer.
