(Medical Xpress)—In the battle against aging and age-related neurological diseases such as Parkinson's and Alzheimer's, a key factor has long appeared to be the toxicity of proteins which tend to aggregate. Recently, scientists ...
A team of researchers including Jens Hansen, Rachel Sealfon, Rajastree Menon, and colleagues of the Kidney Precision Medicine Project, built on an existing specific human kidney tissue atlas relevant to health care at single-cell ...
(Medical Xpress)—Membrane fusion is a highly regulated event, both inside cells, and between them. From the moment a sperm first fuses with an egg, subsequent developmental events depend upon its proper control. Inside ...
An international team of scientists have identified for the first time a key factor responsible for declining muscle repair during ageing, and discovered how to halt the process in mice with a common drug. Although an early ...

Our genetic code includes more than 15,000 specific sections that can be made into molecules called lincRNAs. Some of these sections can occur in coiled-up sections of our genome called TADs. LincRNAs derived from TADs appear ...

Muscle (from Latin musculus, diminutive of mus "mouse") is the contractile tissue of the body and is derived from the mesodermal layer of embryonic germ cells. Muscle cells contain contractile filaments that move past each other and change the size of the cell. They are classified as skeletal, cardiac, or smooth muscles. Their function is to produce force and cause motion. Muscles can cause either locomotion of the organism itself or movement of internal organs. Cardiac and smooth muscle contraction occurs without conscious thought and is necessary for survival. Examples are the contraction of the heart and peristalsis which pushes food through the digestive system. Voluntary contraction of the skeletal muscles is used to move the body and can be finely controlled. Examples are movements of the eye, or gross movements like the quadriceps muscle of the thigh. There are two broad types of voluntary muscle fibers: slow twitch and fast twitch. Slow twitch fibers contract for long periods of time but with little force while fast twitch fibers contract quickly and powerfully but fatigue very rapidly.
