Glioblastoma, the most common and deadly form of brain cancer, grows rapidly to invade and destroy healthy brain tissue. The tumor sends out cancerous tendrils into the brain that make surgical tumor removal extremely difficult or impossible. Now, scientists have found the immunotherapy treatment anti-CTLA-4 leads to considerably greater survival of mice with glioblastoma. Furthermore, […]
E-cigarettes and marijuana have similar harmful effects on the heart as tobacco cigarettes, opening the door to abnormal heart rhythms, reports a team of researchers at UC San Francisco. “We found that cigarettes, e-cigarettes, and marijuana greatly interfere with the electrical activity, structure, and neural regulation of the heart,” said lead author Huiliang Qiu, MD, […]
Over 20 years, a new research team examined people’s regular dietary intake, paying particular attention to non-nutritive sweeteners commonly found in artificial sweeteners. They found that long-term consumption of aspartame, saccharin and diet beverages were linked to increased fat stores in the abdomen and fat within muscle. “This study showed that habitual, long-term intake of […]
July 2023 was the hottest month on record, with cities like Phoenix experiencing record-breaking heat waves for weeks on end. A new study finds that ongoing extreme heat can worsen cognitive decline among vulnerable groups — particularly Black older adults and those living in poor neighborhoods. Extreme heat is the leading cause of weather-related deaths […]
Nanovesicles can be bioengineered to target cancer cells and deliver treatments directly, according to research at Binghamton University, State University of New York. Two unfortunate facts about chemotherapy: It can harm healthy cells as well as cancerous ones, and many therapeutic targets stay within cancer cells, making them harder to reach. Binghamton University biomedical engineers […]
Atherosclerosis is a disease in which fat, cholesterol, and other substances build up inside artery walls. This can lead to plaque formation, which can block arteries and cause heart attacks and strokes. Immune cells play a key role in cleaning the blood, by interacting with red blood cell extracellular vesicles (RBCEVs), which are nano-sized particles […]
Global prevalence of Spinal Cord InjuryI is estimated to be between 0.7 and 1.2 million cases per year, with falls and road accidents being the major causes. Despite incurring a cost of $4 billion per year in direct healthcare and indirect costs in the US alone, there are no licensed drugs that can tackle the […]
Older adults who play digital puzzle games have the same memory abilities as people in their 20s, a new study has shown. The study, from the University of York, also found that adults aged 60 and over who play digital puzzle games had a greater ability to ignore irrelevant distractions, but older adults who played […]
Arterial stiffness is a novel cause of premature heart damage among adolescents, according to a new follow-up study. The study was conducted in collaboration between Texas Children’s Hospital and Baylor College of Medicine in the US, the University of Bristol in the UK, the University of Exeter in the UK, and the University of Eastern […]
Antibiotics work by targeting specific parts of a bacteria cell, such as the cell wall or its DNA. Bacteria can become resistant to antibiotics in a number of ways, including by developing efflux pumps — proteins that are located on the surface of the bacteria cell. When an antibiotic enters the cell, the efflux pump […]
