21 Feb 2018 21 Feb 2018 A Measure of Cerebrospinal Fluid Flow Suggests that Brain Aging Commences Early Loading… Loading… There is a growing faction in the neurodegenerative research community whose members think it likely that rising levels of metabolic waste in brain, such as tau and amyloid aggregates, are due to failing drainage of…

This isn’t the first paper I’ve seen to argue the point that there should be a greater focus on tau aggregation in Alzheimer’s disease, and that tau may be more important to the progression of the condition. As I’m sure the readers here are aware, Alzheimer’s is characterized by the buildup of both amyloid-β and…

MINNEAPOLIS — February 21, 2018 — Results from a retrospective study of 1,629 patients with non-Hodgkin lymphoma (NHL) showed that survival at 4 years following allogeneic hematopoietic cell transplantation (HCT) for patients age 65 years and older is comparable to patients age 55 to 64 years. The study demonstrates that age alone should not be…

In 2011 a research group published the results from an animal study that demonstrated, in a way that couldn’t be ignored, that the accumulation of senescent cells is a significant cause of aging and age-related disease. In fact, the evidence for this to be the case had been compelling for a very long time –…

Researchers here report on their efforts to build a suitable structure to replace a trachea, starting with patient cells and artificial scaffolds. Since the trachea is a thin-walled pipe, engineered tissue can be constructed in this way without the need for complex blood vessel networks, as at no point is the tissue so thick as…

Astrocytes are one of the common types of support cell in the brain, performing a wide variety of tasks that range from repair to maintaining the balance of various signal and electrolyte molecules. Researchers find evidence to suggest that astrocytes shift into an inflammatory mode in large numbers with advancing age. Chronic inflammation is a…

An analysis of recent Medicare billing records for more than 3,000 hospitals across the United States shows that charges for outpatient oncology services such as chemo infusion or radiation treatment vary widely and exceed what Medicare will pay by twofold to sixfold. A report of the findings, published in the American Journal of Managed Care…

Several childhood cancer cell types show features of immature neural cells, and there is evidence suggesting that these tumors may arise from neural crest stem cells that underwent abnormal changes during embryonic development. One such cancer is Ewing sarcoma. Although combinatorial treatment protocols encompassing chemotherapy, surgery, and radiotherapy have improved outcomes, many patients still suffer…
