Researchers adopt new approach to treating advanced prostate cancer

Scientists have proposed a new approach to preventing the proliferation of prostate tumor cells that are no longer responding to treatment. Prostate cancer can usually be cured via surgical removal of the tumor and/or the use of radiotherapy, but in one-fifth of cases, patients also require treatment with drugs to continue removing tumor cells. However, these drugs are only effective for up to three years, after which the cancer continues to develop.

Researchers discover new way to attack drug-resistant prostate cancer cells

In most cases, prostate cancer is cured by surgical removal of the tumor and/or by radiotherapy. However, 20% of patients will need treatment to remove tumor cells but this treatment ceases to be effective after two or three years and the cancer develops further.

Russian researchers create new approaches to prevention and treatment of diabetes

A team of scientists from the Ural Federal University and the Institute of Immunology and Physiology modeled type 1 diabetes in an experiment to study recovery processes in the pancreas.

Conventional sunscreens do not block skin damage caused by visible light

There is something wrong with people's exposure to sunlight. Despite rising worldwide consumption of sunscreens, the number of cases of skin cancer continues to grow. One of the reasons may be the action of visible light, which is also harmful to skin and is not blocked by conventional sunscreens.

Multiple sclerosis drug can beat obstinate bacteria

Encountering bacteria with innocent names such as Pseudomonas aeruginosa and Enterobacteriaceae can lead to hospitalization and - in a worst-case scenario - can also be life-threatening. The bacteria, which cause infections such as pneumonia, frequently develop multi-resistance towards classic antibiotics.

Diabetes patients’ immune system can regulate insulin production

Inflammation processes are responsible for the failure of insulin production in diabetes patients. The patients' own immune systems can contribute to treatment of this disease: researchers at the University of Basel and University Hospital Basel have found a feedback mechanism that could help maintain insulin production in overweight sufferers, as they report in the journal Immunity.

Scientists one step closer to solving puzzle of how nerves can self-heal

Monash University scientists are one step closer to solving the riddle of how nerves can self-heal. The scientists from the Biomedicine Discovery Institute (BDI) have found signals in the tiny transparent roundworm that control the mechanism by which severed nerves self-heal.

Researchers discover how traffic jam in intracellular sorting can cause tumor development

For tissues to cooperate and perform normal functions, cells need to know which way is up. When cells lose track of their orientation, they can start to grow out of control, and develop into cancer.

Canadian and Israeli researchers join forces for new research program

The Joint Canada-Israel Health Research Program is a seven-year, CA$35 million partnership between the Azrieli Foundation, Canada's International Development Research Centre, the Canadian Institutes of Health Research, and the Israel Science Foundation that draws on the scientific strengths of Canadian and Israeli researchers in the broad field of biomedicine.

Researchers produce 3D map of molecular 'scaffold' known to play key role in cancers

Researchers have produced the first three-dimensional (3D) map of a molecular 'scaffold' called SgK223, known to play a critical role in the development and spread of aggressive breast, colon, and pancreatic cancers.

Study demonstrates beneficial effects of calorie-restricted diet in mice

Caloric restriction diets have been associated with various health benefits, but their effects on the skin have not been previously demonstrated. Research conducted at the University of São Paulo (USP) in Brazil shows that controlling calories helps mice live longer, although it reduces the reserves of fat in adipose tissue needed to keep the body warm.

Newly identified microRNA impedes malignancy of tumor cells and metastasis

Cancer cells can reactivate a cellular process that is an essential part of embryonic development. This allows them to leave the primary tumor, penetrate the surrounding tissue and form metastases in peripheral organs.

CHOP researchers discover key differences among gene fusions in childhood brain tumors

Researchers investigating pediatric low-grade gliomas, the most common type of brain tumor in children, have discovered key biological differences in how mutated genes combine with other genes to drive this childhood cancer.

Blood samples may help identify most sensitive patients before radiation and chemotherapy

How much radiation or chemotherapy can a certain person handle? With help from blood or tissue testing, it may be possible to answer this question in advance, which in turn could improve treatment, as research at Sahlgrenska Academy shows.

UTHealth’s bioinformatician receives $5.8 CPRIT grant to sort out cancer data for finding cures

In keeping with the shift in cancer research from data generation to data analysis, bioinformatician W. Jim Zheng, Ph.D., of The University of Texas Health Science Center at Houston has been awarded a five-year, $5.8 million Cancer Prevention & Research Institute of Texas grant to sort out information that could lead to cancer cures.

Analytical Science in Precision Medicine

Pittcon is an analytical conference, so naturally my talk will be about analytical chemistry and how analytical chemistry will become increasingly important in delivering healthcare solutions, not only for rich people, but also, hopefully, for poor people across the world.
