As we age, our bodies change and degenerate over time in a process called senescence. Stem cells, which have the unique ability to change into other cell types, also experience senescence, which presents an issue when trying to maintain cell cultures for therapeutic use. While there are methods to remove older cells in a culture, […]
When COVID-19 began spreading across the globe in early 2020, physicians knew that the virus primarily infected cells in the respiratory tract. But as the case numbers began to grow, physicians were surprised to see that many patients were also developing injuries to their kidneys. The issue came to Samira Musah’s attention when she attended […]
Older people who have fluctuating levels of cholesterol and triglycerides may have a higher risk of Alzheimer’s disease and related dementias compared to people who have steady levels, according to new research published in the July 5, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. While the study found […]
Taking good care of your teeth may be linked to better brain health, according to a study published in the July 5, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study found that gum disease and tooth loss were linked to brain shrinkage in the hippocampus, which plays […]
PPIs are used to treat acid reflux, peptic ulcers, and indigestion. They are among the top 10 most commonly used drugs worldwide. In 2014, the global prevalence of type 2 diabetes was 8.5%, and the researchers wanted to find out if the widespread use of PPIs and the high prevalence of diabetes might be linked. […]
Researchers identified how genetic differences that alter a specific protein called ETS1 can affect our body’s response to allergies. They found that small changes in ETS1 in an animal model can lead to an increased likelihood for allergic reactions that cause inflammation. The United States Centers for Disease Control and Prevention reports that allergies rank […]
The Health Insurance Review & Assessment Service revealed that over the last year, more than 370,000 Koreans sought medical help for infertility or difficulties in conceiving. This represents a 4.7 percent increase in infertility-related treatments and a 16 percent rise in subfertility-related treatments compared to the 2018 data. Korea’s birth rate may be declining, but […]
A reduction in the amount of time spent physically active when adults are over sixty years old is linked to lower quality of life, a Cambridge study of almost 1,500 adults has shown. The same was also true for increases in the amount of sedentary time, such as watching TV or reading. The researchers say […]
In a new study, researchers in the UK and China found that 12 hours a week was the optimal amount of reading, and that this was linked to improved brain structure, which may help explain the findings. During childhood and adolescence, our brains develop, making this an important time in which to establish behaviors that […]
Multiple sclerosis (MS) is the result of the immune system mistakenly attacking the brain and the spinal cord, resulting in symptom flares known as relapses as well as longer-term degeneration known as progression. Despite the development of effective treatments for relapses, none can reliably prevent the accumulation of disability. A study of more than 22,000 […]
