Inclusion of Almonds in a Cholesterol-Lowering Diet Improves Plasma HDL Subspecies and Cholesterol Efflux to Serum in Normal-Weight Individuals with Elevated LDL Cholesterol. The Journal of Nutrition, 2017; 147 (8): 1517 DOI: 10.3945/jn.116.245126

Eating almonds regularly may help improve HDL cholesterol levels, functionality. Eating almonds on a regular basis may help boost levels of HDL cholesterol while simultaneously improving the way it removes cholesterol from the body. In a study, researchers compared the levels and function of high-density lipoprotein (HDL cholesterol) in people who ate almonds every day, to the HDL levels and function of the same group of people when they ate a muffin instead...

Researchers in China have engineered bendable batteries that can run on body-inspired liquids such as normal IV saline solution and cell-culture medium. In their work the authors designed alternatives to lithium-ion batteries by focusing on the mechanical-stress demands of wearable electronics such as smartwatches and the safety requirements of implantable electronics.

“Current batteries like the lithium-ion ones used in medical implants generally come in rigid shapes,” says Yonggang Wang, a chemistry professor at Fudan University and the C...

A new study by University of Kentucky Markey Cancer Center researchers shows that when therapy-sensitive cancer cells die, they release a “killer peptide” that can eliminate therapy-resistant cells. Tumor relapse is a common problem following cancer treatment, because primary tumor cells often contain therapy-resistance cancer cells that continue to proliferate after the therapy-sensitive cells have been eliminated.

In the new study, published in Cancer Research, Markey scientists identified a Par-4 amino-terminal fragment (PAF) that is released by diverse therapy-sensitive cancer cells following therapy-induced cleavage of the tumor suppressor Par-4 protein...
