Experts issue 'blueprint for action' to combat shortages of life-saving drugs
- Details
- Category: Research
A group of prominent healthcare experts including bioethicists, pharmacists, policymakers and cancer specialists have proposed concrete steps for preventing and managing a nightmare scenario that is becoming all too common: shortages of life-saving drugs. In a consensus statement published in the journal Pediatrics, the experts say they sought to move away from the current strategy of reaction to shortages once they have occurred and focus instead on prevention.
Body kills 'spontaneous' blood cancers on a daily basis

- Category: Research
Immune cells undergo 'spontaneous' changes on a daily basis that could lead to cancers if not for the diligent surveillance of our immune system, Melbourne scientists have found. The research team from the Walter and Eliza Hall Institute found that the immune system was responsible for eliminating potentially cancerous immune B cells in their early stages, before they developed into B-cell lymphomas (also known as non-Hodgkin's lymphomas). The results of the study were published in the journal Nature Medicine.
Protein serves as a natural boost for immune system fight against tumors

Substances called adjuvants that enhance the body's immune response are critical to getting the most out of vaccines. These boosters stimulate the regular production of antibodies - caused by foreign substances in the body - toxins, bacteria, foreign blood cells, and the cells of transplanted organs.
Melatonin shows potential to slow tumor growth in certain breast cancers

- Category: Research
Silk and diamonds aren't just for ties and jewelry anymore. They're ingredients for a new kind of tiny glowing particle that could provide doctors and researchers with a novel technique for biological imaging and drug delivery. The new particles, just tens of nanometers across, are made of diamond and covered in silk.
All FDA drug approvals not created equal

- Category: Research
Many patients and physicians assume that the safety and effectiveness of newly approved drugs is well understood by the federal Food and Drug Administration (FDA) - but a new study by researchers at Yale School of Medicine shows that the clinical trials used by the FDA to approve new drugs between 2005 and 2012 vary widely in their thoroughness. Published in the Jan. 22/29 issue of JAMA, the study is the first systematic analysis of the standard used by the FDA in making drug approval decisions.
Researchers discover potential drug targets for early onset glaucoma
- Details
- Category: Research
Using a novel high-throughput screening process, scientists have for the first time identified molecules with the potential to block the accumulation of a toxic eye protein that can lead to early onset of glaucoma. Researchers have implicated a mutant form of a protein called myocilin as a possible root cause of this increased eye pressure. Mutant myocilin is toxic to the cells in the part of the eye that regulates pressure.
