Protein 'Spat Out' By Cancer Cells: Promotes Tumor Growth

Prostate cancer cells change the behaviour of other cells around them; including normal cells, by ‘spitting out’ a protein from their nucleus; new research has found. The tiny pieces of protein are taken up by the other cells; provoking changes that promote tumour growth and; the researchers believe; help the cancer hide from the body’s…

New Treatment Using Smartphone For Virtual Reality

A fully self-guided treatment using virtual reality (VR) is effective in reducing fear of heights. A team of researchers from Vrije Universiteit Amsterdam. Current VR technology most commonly uses virtual reality headsets or multi-projected environments, sometimes in combination with physical environments or props, to generate realistic images, sounds and other sensations that simulate a user’s physical presence…

No Evidence That Calcium Increases Risk Of AMD

Eating a calcium-rich diet or taking calcium supplements does not appear to increase the risk of age-related macular degeneration (AMD); according to the findings of a study by scientists at the National Eye Institute (NEI). AMD is a leading cause of vision loss and blindness among people age 65 and older in the United States.…

Centre Notifies New Rules For Drugs, Clinical Trials

Clinical trials are experiments or observations done in clinical research. Such prospective biomedical or behavioral research studies on human participants are designed; to answer specific questions about biomedical or behavioral interventions; including new treatments (such as novel vaccines, drugs, dietary choices, dietary supplements, and medical devices); and known interventions that warrant further study and comparison.…

Blood Forming Stem Cells Facilitate Mobilization Procedures

Scientists at Winship Cancer Institute of Emory University, Children’s Healthcare of Atlanta and Georgia Tech have found that modulating blood-forming stem cells’ stiffness could possibly facilitate mobilization procedures used for stem cell-based transplants. Temporary squishiness could help drive blood forming stem cells out of the bone marrow and into the blood, but the cells need…

Palliative care

Early Palliative Care Give No Benefit For Mesothelioma Patients

Early specialist palliative care treatment does not improve the quality of life for patients diagnosed with the rare cancer mesothelioma when compared to standard care alone, new research led by Curtin University has found. The research, published in this month’s edition of Thorax, explored whether early specialist palliative care, which involves managing the physical, emotional and spiritual…

New Faster Diagnosis Standard for Cancer

GPs will have a pivotal role in ensuring the success of the new Faster Diagnosis Standard (FDS) for Cancer; new research from the University of Surrey finds. In the first study of its kind; published in the British Journal of General Practice and funded by Cancer Research UK;researchers investigated public attitudes towards the new FDS…

Medicaid Coverage For Lung Cancer Screening

State Medicaid programs must do more to make sure that people at high risk for lung cancer are screening for the deadly disease. Medicaid is the public assistance program offering health care coverage for low-income Americans. Medicaid coverage for screening high-risk people varies widely between states: 31 Medicaid fee-for-service programs cover screening; 12 programs do…

Red Yeast Rice Supplement Has The Potential To Cause Liver Damage

Red yeast rice supplement has the potential to cause liver damage; warn doctors in the journal BMJ Case Reports after a 64-year old woman developed acute liver injury after six weeks of taking the supplement. Red yeast rice is a supplement made by fermenting steamed rice with food fungus and is often using to lower…

Engineering Cellular Function Without Living Cells

Genes in living cells are activated — or not — by proteins called transcription factors. The mechanisms by which these proteins activate certain genes and deactivate others play a fundamental role in many biological processes. However, these mechanisms are extremely complex and scientists have been spending years trying to unlock their secrets. So, scientists usually…

Walking Downhill After Meals: Boosts Bone Health

Walking downhill after eating can reduce bone resorption, the process in which old bone is broken down and removed from the body, in postmenopausal women with diabetes, according to research to be presented at ENDO 2019, the annual meeting of the Endocrine Society, in New Orleans, La. Walking uphill does not have the same benefit,…

Cellular HIV-reservoirs To Self-destruction

While current therapies for HIV can successfully manage active infection, the virus can survive in tissue reservoirs, including macrophage cells, and remain a persistent problem. Now, Dr. David Russell, William Kaplan Professor of Infection Biology at Cornell University College of Veterinary Medicine, and his research team have pinpointed a novel angle of attack that could…
