Photoactive bacteria bait may help in fight against MRSA infections

12.10.2018 Health Problems

Purdue University researchers are testing whether a light-active version of heme, the molecule responsible for transporting oxygen in blood circulation, may help people infected with MRSA. The research was published in the American Chemical Society journal ACS Infectious Diseases in September. The World Health Organization identifies MRSA as one of about a dozen antibiotic “superbugs” that pose an enormous threat […]

Cells in ‘little brain’ have distinctive metabolic needs

11.10.2018 Health Problems

Cells’ metabolic needs are not uniform across the brain, researchers have learned. “Knocking out” an enzyme that regulates mitochondria, cells’ miniature power plants, specifically blocks the development of the mouse cerebellum more than the rest of the brain. The results are scheduled for publication in Science Advances. “This finding will be tremendously helpful in understanding the molecular mechanisms underlying developmental […]

Genetically engineered 3-D human muscle transplant in a murine model

10.10.2018 Health Problems

A growing need for tissues and organs in surgical reconstruction is addressed by the promising field of tissue engineering. For instance, muscle atrophy results from severe traumatic events including deep burns and cancer, requiring site/donor compatible surgical reconstruction. The existing ‘gold standard’ treatment in reconstructive surgery incorporates autologous flaps, although the technique is limited by low anatomical availability and donor […]

Bug that causes stomach cancer could play a role in colorectal cancer

10.10.2018 Health Problems

A bacterium known for causing stomach cancer might also increase the risk of certain colorectal cancers, particularly among African Americans, according to a study led by Duke Cancer Institute researchers. The finding, published online Oct. 5 in the journal Gastroenterology, describes an association between antibodies to H. pylori bacteria and an increased risk of colorectal cancers, although it does not […]

Protein has unique effects in neural connections related to information processing

09.10.2018 Health Problems

Our cognitive abilities come down to how well the connections, or synapses, between our brain cells transmit signals. A new study by researchers at MIT’s Picower Institute for Learning and Memory digs deep into the molecular mechanisms that enable synaptic transmission to show the distinct role of a protein that when mutated has been linked to causing intellectual disability. The […]

New discovery restores insulin cell function in type 2 diabetes

08.10.2018 Health Problems

By blocking a protein, VDAC1, in the insulin-producing beta cells, it is possible to restore their normal function in case of type 2 diabetes. In preclinical experiments, the researchers behind a new study have also shown that it is possible to prevent the development of the disease. The findings are published in the scientific journal Cell Metabolism. The researchers at […]

Liver transplant, weight-loss surgery combination benefits obese patients in long term

06.10.2018 Health Problems

Obese patients who underwent a life-saving liver transplant and weight-loss surgery at the same time were better able to keep the weight off long term and had fewer metabolic complications than those who lost weight on their own before undergoing a liver transplant, Mayo Clinic research shows. The findings were recently published in Hepatology. “This study shows that the combined […]

Alarm as Red Cross workers attacked in Congo Ebola efforts

06.10.2018 Health Problems

The international community is sounding new alarm after three Red Cross workers were attacked while trying to contain the latest deadly Ebola outbreak in Congo. The U.N. Security Council seeks an immediate end to hostilities as it leaves for a Congo visit Thursday. Human Rights Watch urges an investigation into massacres that have killed over 200 civilians this year in […]

Triple dual therapy significantly improves lung function, quality of life in COPD patients

06.10.2018 Health Problems

The InforMing the PAthway of COPD Treatment (IMPACT) study was conducted to assess the benefits of triple versus dual therapy in patients with COPD. In a study at CHEST, researchers found that regardless of baseline reversibility, the usage of triple dual therapies significantly reduced the annual rate and moderate-to-severe and severe exacerbations, improved lung function and overall quality of life […]

AI could predict cognitive decline leading to Alzheimer’s disease in the next five years

05.10.2018 Health Problems

A team of scientists has successfully trained a new artificial intelligence (AI) algorithm to make accurate predictions regarding cognitive decline leading to Alzheimer’s disease. Dr. Mallar Chakravarty, a computational neuroscientist at the Douglas Mental Health University Institute, and his colleagues from the University of Toronto and the Centre for Addiction and Mental Health, designed an algorithm that learns signatures from […]
